                    <description><![CDATA[<p>My mind has been on over-drive, for several possible reasons (no particular order):</p><ul><li>meeting interesting people</li><li>delirium of sickness<br /></li><li>pseudoephedrine + paracetamol + codeine (a.k.a. the double-edged sword that is Coldral)<br /></li><li>reading interesting stuff</li></ul>So, things I have been thinking about and trying to find more information on:<br /><ul><li>paradoxes (e.g. <a href="http://en.wikipedia.org/wiki/Achilles_and_the_turtle">Achilles and the turtle</a>)</li><li>the origin of the <a href="http://en.wikipedia.org/wiki/The_wheel">wheel</a> (i.e. Mesopotamia - ah, good ol' 3rd form history)</li><li><a href="http://www.celsias.com/">www.celsias.com</a>, sustainability and climate change</li><li>how to train people</li><li>Web 2.0 and semantic web (e.g. <a href="http://en.wikipedia.org/wiki/FOAF_%28software%29">FOAF</a>) and trends</li><li>compartmentalisation of online identities</li><li>various projects on my mind</li><li>Africa (e.g. <a href="http://en.wikipedia.org/wiki/Rwandan_Genocide">Rwandan Genocide</a>)<br /></li><li>the <a href="http://en.wikipedia.org/wiki/History_of_the_People%27s_Republic_of_China_%281949%E2%80%931976%29">Cultural Revolution of the Mao Era</a></li><li><a href="http://en.wikipedia.org/wiki/2008_unrest_in_Tibet">Tibet</a></li><li>also reading <a href="http://en.wikipedia.org/wiki/2008_unrest_in_Tibet">The God Delusion</a> by Richard Dawkins, I want to read <a href="http://en.wikipedia.org/wiki/2008_unrest_in_Tibet">A Blank Slate</a> (Pinker) and <a href="http://en.wikipedia.org/wiki/A_clockwork_orange">A Clockwork Orange</a> (Burgess) and a whole bunch of other books I spotted at the library</li><li>teenage violence</li><li>role models/leadership in NZ and around the world</li></ul>I would comment on them, but I'm actually very tired and still sick! Actually, on the topic of pseudoephedrine - it had the craziest effects on me and markedly increased my heart-rate, blood pressure (adrenergic receptors) and I suspect, my cerebral blood flow leading to inability to sleep and hyperactivity in thinking. It was good at the time, but coming down off the pseudoephedrine also led to unwanted side-effects. I stand by my observation that I lack the active allele that converts codeine to morphine. I never benefit from "plus" medications.<br /><span"font-size:78%;"><br /></span><div><span"font-size:78%;">Technorati Tags : <a href="http://www.technorati.com/tag/Cherrieland" rel="tag">Cherrieland</a>,  <a href="http://www.technorati.com/tag/Life" rel="tag">Life</a>,  <a href="http://www.technorati.com/tag/Pseudoephedrine" rel="tag">Pseudoephedrine</a></span></div><div>From <a href="http://cherrieland.blogspot.com">cherrieland.blogspot.com</a></div><img src="http://feeds.feedburner.com/~r/Cherrieland/~4/260434622" height="1" width="1"/>]]></description>

                    <description><![CDATA[<table><tbody><tr><td><span"font-weight: bold;font-size:130%;" >OCT</span><br /><br /><a href="http://bp1.blogger.com/_2YHl26D-n84/R8KGwF-5ZkI/AAAAAAAACkc/yke6BlzrRE4/s1600-h/oct_01_sm.jpg"><img src="http://bp1.blogger.com/_2YHl26D-n84/R8KGwF-5ZkI/AAAAAAAACkc/yke6BlzrRE4/s320/oct_01_sm.jpg" alt="" border="0" /></a>I was fortunate enough to have a look at the software, hardware of an OCT system today, as well as have my left retina scanned (click image to enlarge)!!! Thanks to Dr. NA, colleagues and also AC, I was able to have this opportunity. Anyway, I remember wondering back during the imaging course why ultrasound was limited to ultrasound - why not shorter wavelengths - and I guess this is the answer. I don't really remembering thinking about it much more than a ponder. I don't really understand the <a href="http://en.wikipedia.org/wiki/Optical_coherence_tomography">explanation given in Wikipedia</a>, but I'll try again at some point. Anyway, it was uber exciting to see this new machine and what it can do - and v. cool I got to go on it!!!<br /></td></tr><tr><td><p><span"font-weight: bold;font-size:130%;" ><br /></span></p><p><span"font-weight: bold;font-size:130%;" >Resources</span><br /></p><p>In other news, I just discovered some cool books/resources in my house I'm going to have to make time to get through. Some of the <span>coolest</span> ones include "Understanding the Universe" , "Land of the Pyramids" and "Mozart" booklets/DVDs. They're aimed at primary school children, but hey - gotta start somewhere, right! I'm v. excited. Well, if you're wondering what 'serious' books I'm reading, I've started <a href="http://www.amazon.co.uk/London-Edward-Rutherfurd/dp/0099201917">London</a> and I need to finish <a href="http://www.amazon.co.uk/Wild-Swans-Three-Daughters-China/dp/0007176155/ref=sr_1_1?ie=UTF8amp;s=booksamp;qid=1203931232amp;sr=1-1">Wild Swans</a>, which I started a millennium ago. Been meaning to go to the library to pick up some books I thought about at <a href="http://cherrieland.blogspot.com/2008/02/long-beach-california.html">LB</a>.<br /></p></td></tr><tr><td><br /><span"font-weight: bold;font-size:130%;" >National Library<br /></span><br />I forgot to mention that there was this little interview thing that happened last Wed at the <a href="http://www.natlib.govt.nz/">Nat Lib</a> about digitisation of national collections. It goes without saying, but the peeps were v. nice and v. interesting. But agreeing to the whole thing made me a bit nervous, because I don't want to be one of those people who seem like they want to get their name/face on everything and really have very little substance. Anyway, all I can do is try my best to be honest and clear about the things I care about.<br /><span"font-size:78%;"><br /></span><div><span"font-size:78%;">Technorati Tags : <a href="http://www.technorati.com/tag/Books" rel="tag">Books</a>,  <a href="http://www.technorati.com/tag/Cherrieland" rel="tag">Cherrieland</a>,  <a href="http://www.technorati.com/tag/Eye" rel="tag">Eye</a>,  <a href="http://www.technorati.com/tag/Life" rel="tag">Life</a>,  <a href="http://www.technorati.com/tag/NationalLibraryofNewZealand" rel="tag">National Library of New Zealand</a>,  <a href="http://www.technorati.com/tag/Opthalmology" rel="tag">Opthalmology</a>,  <a href="http://www.technorati.com/tag/Optical+Coherence+Tomography" rel="tag">Optical Coherence Tomography</a>,  <a href="http://www.technorati.com/tag/Reading" rel="tag">Reading</a></span></div></td></tr></tbody></table><div>From <a href="http://cherrieland.blogspot.com">cherrieland.blogspot.com</a></div><img src="http://feeds.feedburner.com/~r/Cherrieland/~4/240779483" height="1" width="1"/>]]></description>

Wondering why I'm doing these interviews and presentations and trying to change the world and I imagine myself saying, "I'm done."</p><p>...alone, can't sleep, but so tired... felt compelled to have a few drinks, so I did.

                    <link>http://www.tigblog.org/group/health/post/335837</link> 
                    <description><![CDATA[<table><tbody><tr><td>Alright, there are several topics to update you on and they are:<br /><br /><span"font-weight: bold;font-size:130%;" >Speak: Computer Clubhouse Meeting<br /></span><span>Wellington City Council</span><br /><br />Short presentation on <a href="http://www.takingitglobal.org/">TakingITGlobal.org</a> today - mainly about how to engage young people in this 'modern age'... i.e. how to inspire, inform, involve. =) Think it went pretty well in terms of promoting the power of young people and TIG, but did virtually no good for my own promotion - which is fine and something I'm trying to practise. At first, I wasn't sure what to feel coming in between these two other speakers who are pretty awesome and spoke of their own stories. But hopefully, diverting the attention away from personal achievements brought in the wider picture of engaging young people as a whole. I'm not saying the TC and TM did not have a lot to offer - for sure they did and did a wonderful job of showcasing what young people think about and can do - I'm just saying that I'm learning to complement that sort of achievement by bringing a wider picture message when I see fit, even when I had the urge to try and stand up as tall as those guys could and say, "hey!! I did stuff, too!" Again, NO I'M NOT TRYING TO COMPARE MYSELF TO THEM, I'm just saying, I'm learning other things now. Actually, I was pretty impressed by them, which is cool.<br /></td></tr><tr><td><br /><span"font-weight: bold;font-size:130%;" >Yell: CE 'Red Rocket' Dragonboating</span><br /><span>Wellington Harbour</span><br /><br /><a href="http://bp0.blogger.com/_2YHl26D-n84/R7lXPF-5ZjI/AAAAAAAACkU/gOc_ZSxv-7Q/s1600-h/IMG_0158.JPG"><img src="http://bp0.blogger.com/_2YHl26D-n84/R7lXPF-5ZjI/AAAAAAAACkU/gOc_ZSxv-7Q/s320/IMG_0158.JPG" alt="" border="0" /></a>Dragonboating practises have been great! I really enjoy being the drummer - yelling is doing something good to my soul... or whatever. It's just pretty fun feeling the wind in your face and the water drenching you every couple of minutes. I feel so proud of the team working so hard to increase their stamina and timing... sometimes I feel a bit bad being one who doesn't paddle, but I guess I have my role, too. And I am slowly learning that.  The team is pretty cool and the coach is super awesome. Also, yelling is really opening up my voice and I'm noticing that in my "singing" (if it can even be called that). =P<br /></td></tr><tr><td><br /><span"font-weight: bold;font-size:130%;" >Run: Wellington Round The Bays</span><br /><span>Wellington Bays (Frank Kitts Park - Kilbirnie Park)</span><br /><br /><a href="http://admin.eventdirector.net/RESOURCES/SPWEL/SITES/191/ZUSER/map_web.jpg"><img src="http://admin.eventdirector.net/RESOURCES/SPWEL/SITES/191/ZUSER/map_web.jpg" alt="" border="0" /></a>Round the Wellington Bays, which are apparently worth $6 more than the Auckland ones. To be fair, there are probably fewer participants (to recoup costs) and a different sponsor. This one is a shorter race - 7 km compared to Auckland's 8.4 km. But a much nicer race, as it is not so blazing hot and there is some good wind in some patches.<br /><br />I had a good time doing it, though there were times when I wanted to stop! I managed NOT to stop, so am quite happy about that and added to the fact I finished in 35: 45, meaning I improved my speed (if at same speed as <a href="http://cherrieland.blogspot.com/2007/10/auckland-quarter-marathon.html">Auckland Quarter Marathon</a>, would expect ~ 40 min). So, yay! I'm a bit sore today though.<br /></td></tr><tr><td><br /><span"font-size:130%;"><span"font-weight: bold;font-size:130%;" >Also 1: Work</span> </span>I had a much better day at work today - I'm always happier when I have adequate feedback and know what I'm supposed to be doing. :)<br /><br /><span"font-weight: bold;font-size:130%;" >Also 2: Family </span>Molestor 2008 moved out yesterday, so that now it's sort of quiet around the house. Whose groin do I kick now? (private joke, don't ask and no, it's not what you think)</td></tr></tbody></table><br /><span"font-size:78%;"><br /></span><div><span"font-size:78%;">Technorati Tags : <a href="http://www.technorati.com/tag/Cherrieland" rel="tag">Cherrieland</a>,  <a href="http://www.technorati.com/tag/Dragonboating" rel="tag">Dragonboating</a>,  <a href="http://www.technorati.com/tag/Life" rel="tag">Life</a>,  <a href="http://www.technorati.com/tag/Running" rel="tag">Running</a>,  <a href="http://www.technorati.com/tag/Work" rel="tag">Work</a></span></div><div>From <a href="http://cherrieland.blogspot.com">cherrieland.blogspot.com</a></div><img src="http://feeds.feedburner.com/~r/Cherrieland/~4/236901060" height="1" width="1"/>]]></description>

                    <description><![CDATA[<p>Crap-doozles, I just had a quick squiz over my 2008 postings and boy have they been dense. Sorry, mates - must have been a bit too absorbed in the mind. WHY DIDN'T YOU WARN ME!!!! =P Anyway, onto the LB of the CA, the B-phys for the scien-tists... I should be a rapper. I'm finding it hard to filter at the moment, so I'll just do a mind-dump and try highlight the more interesting parts. Anyway, for those who don't know or can't remember - the <a href="http://www.biophysics.org/">Biophysical Society</a> has an annual meeting for biophysicists around the world to communicate their research. This year, I was lucky enough to be sponsored by my lab group (warm fuzzies) to go present the research I did last year. Yes, "research I did" still cracks me up.</p><span"font-weight: bold;font-size:180%;" >I. Anticipating</span><br /><p><span><span"font-size:130%;">Waiting and Delays</span><br /></span></p><p><a href="http://bp0.blogger.com/_2YHl26D-n84/R67XK1-5ZiI/AAAAAAAACkM/0U5QRDkORgE/s1600-h/02012007.jpg"><img src="http://bp0.blogger.com/_2YHl26D-n84/R67XK1-5ZiI/AAAAAAAACkM/0U5QRDkORgE/s320/02012007.jpg" alt="" border="0" /></a>Arriving monstrously early at Wlg airport means spending a monstrous number of hours in a place with nothing to do. Fortunately, I was in an extremely agreeable mood, so I thought nothing of it. I don't mind delays, either, as long as they don't interfere with my schedule. I can entertain myself just fine, thank you.<br /></p><p>What <span>did</span> touch a few nerves was <span>"we are late for departure due to the plane's late arrival."</span> What does that statement even achieve except for try to blame someone else? Weird.<br /></p><p><span"font-weight: bold;font-size:130%;" >The Walk</span></p><p><a href="http://en.wikipedia.org/wiki/The_World_According_To_Clarkson">Jeremy Clarkson</a> does not speak highly of the walk between Auckland domestic and international airports. His description would have me think that someone was forcing him to run a marathon with his luggage... uphill... and on one leg. It was actually very short, very easy and very bland. Poor Clarkson. I'll still read his books though, coz he's damn funny.</p><p><span"font-size:130%;"><span>To Gate 10 and a little Paranoid Story</span></span><br /></p><p><a href="http://bp2.blogger.com/_2YHl26D-n84/R65G_V-5ZeI/AAAAAAAACjs/_-UOrVGLii4/s1600-h/FD_paranoid.jpg"><img src="http://bp2.blogger.com/_2YHl26D-n84/R65G_V-5ZeI/AAAAAAAACjs/_-UOrVGLii4/s320/FD_paranoid.jpg" alt="" border="0" /></a>Barely able to contain the excitement bubbling just under my skin, I made a beeline for Gate 10 (AKL --> LAX), where MC was already. At first I couldn't find him, so that entertained the idea that <span>the entire conference-poster-paper thing is a conspiracy</span> to bring me down before I can build on a reputation and/or career. Similar to my work scenario right now, where giving me huge responsibility and potential to direct change is just a setup to <span>watch me crash and burn</span>. No matter, because I get kicks from a huge potential fall and I don't really think these people are hating on me. =P It's just me self-doubting - <span>why me? Why would they want me?</span></p><p>It was cool to see MC, although I was quite aware that I would have to be very careful about how annoying I am!!! TK is always kindly reminding me of how annoying I am from HK to AKL. Thanks. I don't personally think I'm <span>that </span>annoying, but hey I respect the opinions of others and I <span>don't</span> want to annoy MC.<br /></p><p><span"font-weight: bold;font-size:130%;" >Boarding and Flying</span></p><p><span> </span>Board! Board! Board! So excited. MC recommended <a href="http://www.imdb.com/title/tt0109045/">The Adventures of Priscilla Queen of the Desert</a>. Quite funny, cool costumes and soundtrack. Actually, it was <span>much</span> funnier than I expected. Heh. Some good quotes from there, methinks. I also watched <a href="http://www.imdb.com/title/tt0866437/">The Jane Austin Book Club</a>, which was a chicky flick so you need a bit of patience. A few cutesy, funny bits though. </p><p>On the way back, I watched <a href="http://www.lovehkfilm.com/reviews_2/magic_boy.htm">Magic Boy</a>, which was pretty crap but I enjoyed the HK-flavoured cutesy things. I understand those social things more than any social thing I gather in NZ. Even though I have spent a larger portion of my life here. I also watched most of <a href="http://en.wikipedia.org/wiki/Transformers_%28film%29">Transformers</a>. I will have to watch the ending some time, since I fell asleep. But it totally wasn't what I expected. The whole film is just silly-humour, which I don't mind except that it danced dangerously-close to stupid-humour, like the type you find in teen movies or when some drunk guy pees in a bottle and that's supposed to be funny.</p><p>I sped-listened to a few albums, but I'm still really feeling <a href="http://en.wikipedia.org/wiki/Alicia_Keys">Alicia Keys</a>' <a href="http://en.wikipedia.org/wiki/As_I_Am">As I Am</a>. Note to self, I have to get some in-ear earphones.<br /></p><p><span"font-weight: bold;font-size:130%;" >Arrival</span><br /></p><p><a href="http://bp1.blogger.com/_2YHl26D-n84/R65mvF-5ZfI/AAAAAAAACj0/sFl5sv06wKY/s1600-h/06022008.jpg"><img src="http://bp1.blogger.com/_2YHl26D-n84/R65mvF-5ZfI/AAAAAAAACj0/sFl5sv06wKY/s320/06022008.jpg" alt="" border="0" /></a> AAAAARRRRRRRRRGHH!!! WOW - in L.A.!!! LOS ANGELES. Sweet! All of the excitement over what lies just beyond the known mixing with memories from the <a href="http://cherrieland.blogspot.com/2005/06/akl-la-chicago-philly_27.html">first time</a>. So thrilling to be knocked slightly off axle - not completely sure how things work, where things are...<br /></p><p>As we waited for the shuttle to come, I was amazed by the fact I was in another country again. I was amazed by the different cars, buildings, trees and people... almost a different sky even though I know it is not... I was humbled by the look on people's faces when you give them a genuine smile, <span>as if for a moment they have come out of their own skin</span>. I also marvelled at the length, yet uniformity of a set of false eyelashes the shuttle organiser had on. I wondered whether she had preened herself for work or whether she was meeting someone.<br /></p><p>I think I slept through most of the ride to Long Beach. But as we arrived, I recognised the streets and buildings that I had semi-explored using <a href="http://maps.google.com/maps/ms?ie=UTF8amp;hl=enamp;msa=0amp;msid=114230059218049035123.00044460815c72cbbf8daamp;ll=33.765957,-118.189609amp;spn=0.004237,0.010042amp;t=hamp;z=17amp;om=0">Google Maps</a>. I like having the water nearby because it gives me a reference point and I feel more ready to explore. It's a good feeling.</p><p>We checked into the hotel and it was good to have a few hours just to recharge. I unpacked into roomy drawers and cupboard, then discovered a shower with <span>two</span> shower-heads and a double-lined curtain, hair conditioner that actually works and thick, semi-soft towels and most importantly, a soft yet firm bed with endless pillows, thick yet semi-light duvet and crisp sheets. So heavenly. Although it still doesn't really compare to my own bed. =P<br /></p><span"font-weight: bold;font-size:180%;" >II. There<br /></span><p><span"font-size:130%;"><span>The First Time</span></span><br /></p><p>We registered/picked up stuff and went to talks in the <span>Membrane Biophysics Subgroup (Channel Gating Modifiers and Modulators)</span>. Getting back into the language of science was much easier than I thought and already I was taking comfort in the fact I could communicate with MC without first having to think, "now, how would a business person interpret this?" Likewise, when we met up with CS at the <span>Opening Mixer</span>, it was good to be able to talk as I have talked for a year. I am still quite shocked at why this is so. I also wonder how much CE has changed me and how much more it will. <span>I am still learning to talk two decades after my first word.</span></p><p>I saw MC and CS talk with various colleagues and people introducing themselves to talk of potential connections and collaborations. It was exciting and amusing... I guess you could say that at that stage I hadn't even realised I was overwhelmed - but I was and I'm glad I had those two there.</p><p><span"font-size:130%;"><span>Subsequent Times and Tomorrow<br /></span></span></p><p><span"font-size:100%;">As I attended more sessions and looked at more posters, I began to paint a picture of what Biophysics was all about. I tried to engage in others' research for the subject itself, but also for ideas that may be translated to 'my own' (having 'my own' research still feels weird to me). I was more attracted to methodology and motivation as opposed to the actual conclusions. I wondered whether this reflected the ambiguity and often meaninglessness of conclusions or whether it revealed something about my interest in knowledge and science. <span>Do I like science</span> or do I like knowledge? I think I like science - building knowledge and what it can be used for. In any case, I saw a few projects that made me think about my future project in new ways. They also made me think about problem-solving in a slightly different way.<br /></span></p><p><span"font-size:100%;">I was very aware that I found it difficult to understand a lot of people's work. Again, I didn't know whether it was because they sucked or I sucked. Probably a bit of both, since I am not that familiar with the wide-range of techniques and approaches to problem-solving. I mean, I guess that is why I am here. But I have to admit I am a little disappointed that international level scientists are not better or more attentive towards the <span>communication of their research</span>. Again, people who do not put this effort in can simply not have the right to complain they are misunderstood in their institutions, let alone the general public. I'm not saying that it doesn't take two to tango though. Still, even if people aren't interested in communication for communication's sake (I can't really understand that), then they must still be interested in funding. And funding is so dependent on public pressure, as well as society's value on intellect and Education.</span></p><hr /><span"font-size:130%;">BOX 1: Science, The Unsung Hero</span><br />I find the continuing disinterest in science and <span>thought</span> particularly alarming in the US. I am told that many people in the US do not understand the concept of science, let alone trust it or even know what it has founded. The debate with evolution and intelligent design is huge, feeding growing concern about the quality of education their children are getting.  This is on top of the fact that the US is split into 15,000 individual school districts.<br /><br />In a conversation with someone I highly respect, the frustration was evident when describing society's apparent aversion from anything hard. I guess it's about finding a way to engage students long enough so that they are able to get closer to achievement. Once you feel what it means to achieve something, or get through something hard, you never look back. Psychologists say that lack of motivation can be due to lack of self-esteem. Or is it that people are not understanding integrity? Going all the way with a string of thoughts in life is just as important as following through in a netball game.<br /><br />I'm going to have to carry on with this box in another post, with a brainstorm of things that I/you can do to help the case of science...no, <span>thinking</span>.<br /><p><span><hr /></span><span><span><span"font-size:100%;">There were a few talks that got me really excited about being a part of science and being part of a group that is so complementary to my values. A lot of my skills are just seeds if anything at all and I am just so excited to see what I can make of them. The learning and teaching, thinking and sharing, knowing and feeling, testing and observing - all seem to describe myself as well as science.  I guess my work right now tests whether I can feel this affinity for something else. Is what I feel with the lab group true? Actually, for a moment I thought perhaps that this group was unique and when I leave for another, I wouldn't care for 'science' as much. I don't know, but I am pretty confident that if that happens, <span>I will still have direction in my life</span>, as I always have.</span></span></span><span><span><span"font-size:100%;"><br /></span></span></span></p><p><span"font-size:100%;">Anyway, I wrote several things down that I need to look up and several things I need to do. Am I good enough? Will I be able to improve? I just heard <a href="http://www.facebook.com/share_redirect.php?h=b1bd9dacbc74b8b6e6bc3decf6787986amp;url=http%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3Dji5_MqicxSoamp;sid=10313166602">Professor Randy Pausch</a> say that you have to cherish feedback and critique because it's when you know you've done something mediocre/pathetic and no-one is telling you that you should worry - <span>because they have given up</span>. I completely agree and it is something I worry about a lot.</span><span><br /></span></p><p><span"font-size:130%;"><span>The Poster and a Starstruck Story<br /></span></span></p><p>My poster was a Sunday poster and I stood by it from 2:45 to 4:30 PM. I don't know how many people saw it and I don't remember how many people asked me questions, but <span>whatever it was, I wanted more</span>. But I think I became a bit too preoccupied with this task, because I didn't get a lot of time to examine the other posters in my category. That's a bit annoying because that would have been the section that I had the highest chances of understanding.<br /></p><p>I did get a chance to scope out some of the people whose names I recognise. That was pretty cool, though I can say that it doesn't compare to the first time I found a paper by CS and noted (I know, I am so observant) that he was <span>just</span> down the hall. I remember telling him this soon after and he seemed sort of surprised/amused at my reaction - I guess he hadn't been aware how ignorant I was regarding how science actually worked. I often wonder whether my ignorance was on par with the average second year undergraduate.</p><p>Anyway, poster day was a bit too stimulating for me - I'd talked a lot, met a lot of people and learnt a lot of things I never imagined knowing. So I ended up in bed by 9 PM - counting sit ups (100, 101...) and kicks, thinking about the day, feeling anxious and excited and realising that I hadn't eaten  since 6:30 PM the night before. Not that I was missing much in terms of great tastes.<br /></p><p>All I have to say is, <span>everyday I realise I am changing</span>. In ways I can hardly predict.<br /></p><p><span"font-weight: bold;font-size:130%;" >Food and Dinners</span><br /></p>Food in the US is notoriously large in portions and high in fat. Yes, yes. All I taste is grease. Oh sorry, yes, also sugar and salt. Did I mention grease? Oh, well you can taste it by smell even if you try to avoid eating it. The trouble with grease is that it makes you want more grease and honestly, a good yoghurt doesn't really compare to a juicy burger. But it's not like I'm going to let a few days in the US ruin my new self-body-image and -esteem. Self-control is key.<br /><p>Dinners in the US were great! I enjoyed all the conversations and laughs... am especially appreciative of the company. It's just that people don't <span>have</span> to be nice to me (or anyone), spend time with me, help me... and yet they do, you know? I'm very grateful for that and very aware of what it takes to get along with me. At the same time (and sort of unrelated to this trip, but nonetheless it's brought up now), I realise that some people associate with me for their own benefits. I am still unsure how to deal with this, as I am still going through the motions of being hurt and embarrassed. I don't even know that I need to be more protective, as that type of change would be an insult to my own integrity. Do you think? I am unsure. I had a few good conversations with MC and CS (separately) and I often wonder what they think. Maybe the day I figure this out will be the day I know I'm ready to graduate. Or something.<br /></p><p>I went to the Graduate Breakfast, which was ok but I thought it was not very well organised. Met some nice people, though not as many as I had expected. Some people were more friendly than others.<br /></p><span"font-weight: bold;font-size:130%;" ><span"font-size:180%;">III. Coming Down</span><br /></span><p><a href="http://bp1.blogger.com/_2YHl26D-n84/R67ClF-5ZgI/AAAAAAAACj8/GcqzhwbhjXg/s1600-h/DSC03704.JPG"><img src="http://bp1.blogger.com/_2YHl26D-n84/R67ClF-5ZgI/AAAAAAAACj8/GcqzhwbhjXg/s320/DSC03704.JPG" alt="" border="0" /></a><span"font-size:130%;">Aquarium of the Pacific</span><br /></p><p>So the <a href="http://www.aquariumofpacific.org/">aquarium</a> is NOT the gigantic structure with sea-life painted all over it. No, it is the <span>other</span> building, three blocks away, that has no animals printed on it whatsoever. Brilliant. Anyway, I really like museums, galleries and collections of that nature, so I was quite enthusiastic about this visit and especially with MC there, who would know lots of izzle to complement the sights. Anyway, the aquarium was very pretty I admit, but lacking in information associated with the displays. That is also ok I guess, since I can look up information later.</p><p></p><hr /><p></p><p><span"font-weight: bold;font-size:130%;" >BOX 2: I'm Creature, I'm Earth, My Mother, My Birth</span><br /></p><p>What really got to me was learning about the distress of the animals, the damage that is brought down upon their habitats and how little anyone cares. Here are beautiful creatures and plants - silent against a backdrop of screaming children running around teachers who seem nonchalant about enriching their students' minds, let alone bringing forth a sense of social and environmental responsibility. There is a curiosity in living things, in our surroundings and how it all works that is crushed by peer pressure.<br /></p><p>Ashamedly, I do recall that I used to be very passionate about my dolphins, whales and environment (I was never into horses, excuse me =P). But somehow that got lost. Maybe it was because I made that speech about the environment that was 2 minutes too long and everyone rolled their eyes at me. Maybe it was because I moved onto college and school-work took over my life. Maybe I just cared less. I don't know. I still have my posters, drawings and books. Hm. Sometimes I feel so apathetic. Am I? Have I become what I promised myself not to become?</p><p>Anyway, I need a few days to downsize a few videos I took. They will be posted soon.</p><p></p><hr /><p></p><p><a href="http://bp1.blogger.com/_2YHl26D-n84/R67DGF-5ZhI/AAAAAAAACkE/xx24AYeDcLU/s1600-h/06022008%28002%29.jpg"><img src="http://bp1.blogger.com/_2YHl26D-n84/R67DGF-5ZhI/AAAAAAAACkE/xx24AYeDcLU/s320/06022008%28002%29.jpg" alt="" border="0" /></a><span"font-weight: bold;font-size:130%;" >Shoreline Village</span></p><p>There was a free afternoon on Wednesday that I spent walking along the waterfront. I like doing that and it feels familiar to me, like the waterfront in Wellington or Auckland. I walked as far as the beach and turned into the city. Again, a stranger nodded hello and walked on by. I am not sure why I am seeing a more friendly side of Long Beach than people have been telling me. That's my shadow in the photo there. </p><p>I also managed to see <a href="http://www.shorelinevillage.com/">Shoreline Village</a> at night later on and that was really cool. I love roaming around, seeing and trying new things, talking to locals, breathing the air... And at night, it's a totally different experience.<br /></p><span"font-weight: bold;font-size:130%;" >The Way Back</span><br /><br />I guess I was sorta sad and very tired on the flight back. I guess it ended too soon, but I feel motivated, inspired and very much grateful and humbled over where I am and what I have.<br /><p><span"font-weight: bold;font-size:180%;" >IV. Summary</span><br /></p>I'm back on Earth, but maybe I have changed again. I have a warm feeling in my stomach that rises up suddenly like bubbles and I can't help but smile. Sometimes it's released as a giggle or even a laugh, but who cares what other people think? I am grateful for the people I have around me and the opportunities I have. There is still uncertainty over what I can do, what will become of me, but I have a much stronger sense of who I am now. I feel so ready to step up and I think I have made that mental move. A little more focussed, a little more alive.<br /><br /><br />Oh, I've started reading "<a href="http://en.wikipedia.org/wiki/The_Lovely_Bones">The Lovely Bones</a>" by Alice Sebold. :) I have recently read "<a href="http://www.amazon.com/Chinese-Room-Vivian-Connell/dp/1419124285/ref=sr_1_2?ie=UTF8amp;s=booksamp;qid=1202640008amp;sr=1-2">The Chinese Room</a>" by Vivian Connell, which I thought was pretty good. I don't know if I mentioned, but I also read "<a href="http://www.amazon.com/As-You-Thinketh-James-Allen/dp/1560871474">As You Thinketh</a>" by James Allen and "<a href="http://books.google.com/books?hl=enamp;id=wXOEiYrR7RACamp;dq=concepts+of+the+selfamp;printsec=frontcoveramp;source=webamp;ots=Mjq-nMtYtYamp;sig=TCDMitNbhMHav8_DIdO5pPeE2mQ">Concepts of the Self</a>" by Anthony Elliot. The latter was pretty good. The former, not so good. I've also read this paper produced by HP regarding the use of Facebook. Ok to dull paper. Been thinking about ICTs in the workplace and society. Have downloaded some papers on science and education, research-related stuff. I want to hit the ground running.  But I have to remember why I am here. I need to learn to drive!!!<br /><span"font-size:78%;"><br /></span><div><span"font-size:78%;">Image Source : <a href="http://www.funkydory.com/FD_paranoid.jpg">www.funkydory.com</a></span><br /><span"font-size:78%;">Technorati Tags : <a href="http://www.technorati.com/tag/Books" rel="tag">Books</a>, <a href="http://www.technorati.com/tag/Biophysics2008" rel="tag">Biophysics2008</a>,  <a href="http://www.technorati.com/tag/Cherrieland" rel="tag">Cherrieland</a>,  <a href="http://www.technorati.com/tag/Conferences" rel="tag">Conferences</a>,  <a href="http://www.technorati.com/tag/Lab" rel="tag">Lab</a>,  <a href="http://www.technorati.com/tag/Life" rel="tag">Life</a>,  <a href="http://www.technorati.com/tag/LongBeach" rel="tag">Long Beach</a>,  <a href="http://www.technorati.com/tag/Science" rel="tag">Science</a></span></div><div>From <a href="http://cherrieland.blogspot.com">cherrieland.blogspot.com</a></div><img src="http://feeds.feedburner.com/~r/Cherrieland/~4/232564388" height="1" width="1"/>]]></description>

                    <title>World Diabetes Day / اليوم العالمي لداء السكري</title> 
                    <link>http://www.tigblog.org/group/health/post/66131</link> 
                    <description><![CDATA[(Arabic Translation follows)<br />
<br />
Today, November 14th, is the World Diabetes Day, which commemorates the discovery of Insulin on 14th November 1921 by Panting and Best. In this day the world brings into focus diabetes which affects some 230 millions and which is the fourth leading cause of death in the whole world. In this day we celebrate the ongoing efforts to control the disease by providing education and awareness to diabetics and giving advice to healthy people on how to protect themselves from the disease and how to discover its occurrence as soon as possible and how to prevent its awful complications.<br />
If you want to know more about this day you can visit its site: www.worlddiabetesday.org <br />
<br />
As long as it's a serious disease, we're going to have a look about it.<br />
Diabetes (mellitus) is a Greek name meaning honey urine denoting that a diabetic patient has sugar in his urine.<br />
The cause of all problems of diabetes is related to Insulin, where there's either a decreased amount or the body isn't responding to it properly. <br />
To understand mechanism of development of the disease, we should know what the insulin does.<br />
 <br />
If you remember your Chemistry classes, you'll recall that there are 3 groups in which different foods are classified; carbohydrates (sugars), proteins and fats. These 3 types are all controlled by insulin. Insulin is a hormone secreted by the pancreas in after meals. It tells the body what to do with the absorbed food with its different types, the most important of which is the sugar represented by glucose. Insulin acts exactly as a passport for glucose and this means that no cell (except for few tissues including liver and intestines) can get glucose without insulin. And for your knowledge, glucose is the most important and most efficient source of energy. As for proteins, insulin stimulates cells to synthesize proteins from the building blocks absorbed from food and this is very important for growth in children which explains why diabetic children has retarded body growth. Insulin decreases the utilization of fats by cells and enhances its storage.<br />
<br />
This tremendously vital action of insulin is impaired in diabetes either due to deficient amount or cells not responding to it. This will lead to:<br />
•	Increased level of glucose in blood despite the starving cells for insulin (they don't have a passport; insulin)<br />
•	Utilization of fats for energy instead of glucose which harms the liver and lead to the release of acidic substances called ketone bodies <br />
•	Impaired protein synthesis which leads to stunted growth in children<br />
<br />
The increased level of glucose in the blood is the most prominent of all the problems. The normal level is between 70-120 mg/dl. When the level reaches 180 mg, glucose appears in urine. This leads to increase in the volume of urine (because of osmotic pressure created by glucose) and the diseased person urinates more frequently than normal. This followed by increased thirst to compensate for the lost water. Also a brain deprived of glucose will be starving which will reflect itself as abnormal hunger which makes the patient always wanting to eat which causes him to be obese. <br />
If the diabetes is left uncontrolled, complications develop, and these are really nasty and leave almost no organ unaffected.<br />
<br />
Eye is very commonly affected…in severe cases it could lead to blindness, and diabetes is the leading cause of blindness in the developed countries.<br />
 <br />
Diabetes predisposes to atherosclerosis (hardening of the wall of arteries) and this paves the way for chronic heart diseases; the leading cause of death in developed countries.<br />
<br />
Another very serious complication is the increased probability of gangrene in foot which is only treated by amputation. This is due to decreased sensation in feet which could be injured easily and thus infected. Also the circulation in extremities is very poor due to affection of the minute vessels there, thus an infection brought by a wound will proceed to a gangrene without any immunity (which is carried out by blood cells) intervening.<br />
<br />
This seems really horrible and this is why diabetics should control their disease by taking medications and improving their life style to guard against the complications. And even better, protect other people from getting diabetes, but how?<br />
<br />
Let's see how the disease starts. We know that the problem is in resistance to insulin or in a decreased amount of it. It goes as follows…<br />
The disease has a very strong genetic predisposition. So if you don't have the disease and have a close relative who's diabetic, be ware that you are in danger of getting the disease. <br />
So an eligible candidate leads a very unhealthy life style eating junky food rich in sugars and fats as he wants and drinks only Pepsi or Coca-Cola. He imposes burden on his pancreas that's always secreting large of insulin. This leads to development of resistance to insulin and cells can no more respond to it properly. If this continues the pancreas will be burned out and will lose the ability to secrete insulin and the patient will be dependant on insulin injection all his life.<br />
There's now overwhelming evidence that having a healthy lifestyle will protect a person from diabetes even if he has many close relatives suffering from the disease.<br />
<br />
<bold>Bottom line:</bold>   <br />
You can protect yourself if you follow healthy lifestyle. Exercise every day, eat a lot of vegetables and don't eat a lot of sugary and fatty staff.<br />
Be ware of your health. If you notice increased frequency of urination with no obvious cause, you should consult a doctor as this is the earliest sign of diabetes.<br />
If you're diabetic, you need to follow your medication schedule strictly.<br />

يحتفل العالم اليوم 14 من نوفمبر باليوم العالمي لداء السكري و هو اليوم الذي يوافق اكتشاف الإنسولين بواسطة بانتينج و بيست  عام  1921. في هذا اليوم يلقي العالم الضوء على السكري (أو السكر كما يسميه الناس في مصر)  و هو مرض يصيب حوالي 230 شخص حول العالم و يعد رابع أهم سبب للوفاة عالميا. ونحتفي في هذا اليوم بالجهود المتواصلة لمحاربة هذا المرض و لنشر الوعي بخطورته و أهمية الوقاية منه و الكشف المبكر عن المصابين به و رعايتهم بصورة لائقة.  و للمزيد عن هذا اليوم يمكنك زيارة الموقع الرسمي: <br />
www.worlddiabetesday.org <br />
<br />
بما أن السكري مرض خطير فسنلقي بعض الضوء عليه و مما يزيد من أهمية مناقشة هذا الموضوع، أن المنطقة العربية تعد من أكثر أماكن العالم من حيث انتشار المرض حيث تبلغ نسبة المصابين به في دول مثل البحرين و الإمارات حوالي 30% من السكان.<br />
ترجع مشاكل السكري كلها إلى سبب واحد هو الإنسولين. و يكون ذلك إما بسبب نقص كمية إفرازه أو مقاومة الجسم له و لنفهم كيف يسبب ذلك مرضا، علينا أن نعرف وظيفة الإنسولين الطبيعية.<br />
<br />
يتحكم الإنسولين في التمثيل الغذائي للمجماميع الغذائية الثلاثة؛ السكريات و الدهون و البروتينات. و الإنسولين هو هرمون يفرزه البنكرياس بعد أي وجبة. و يخبر هذا الهرمون الجسم بما يفعله مع الغذاء الذي تم امتصاصه بمختلف أنواعه و بالخصوص مع السكريات المتمثلة في الجلوكوز. يعمل الإنسولين كتأشيرة دخول للجلوكوز داخل أي خلية و هذا يعني أنأي خلية لن تحصل علي الجلوكوز بدون أن يحمل الجلوكوز تأشيرة الدخول لها. و للعلم، يعد الجلوكوز أهم مصدر للطاقة في الجسم. ينظم الإنسولين أيضا التمثيل الفدائي للبروتينات و الدهون بطرق مختلفة. <br />
<br />
عندما تعتل هذه الوظيفة الحيوية إما بسبب نقص كمية الإنسولين أو مقاومة الجسم له، يعاني من ارتفاع نسبة الجلوكوز في الدم – أكثر من 120 مجم لكل 100مل -  رغم عدم تمكن الخلايا من الإستفادة من هذا الجلوكوز لعدم وجود تأشيرة الدخول. هذا الجلوكوز تخرجه الكلى في البول مما يزيد كمية البول و لذلك يتردد مريض السكري على دورة المياه أكثر من المعتاد. و تبع ذلك زيادة في الإحساس بالعطش لتعويض المياه المفقودة في البول. أيضا يشعر مريض السكري بالجوعدائما  و ذلك لعدم دخول الجلوكوز إلى المخ و المخ لا يستطيع استخدام أي مصدر للطاقو غير الجلوكوز. هذا الجوع يؤدي زيادة في الاكل و البدانة.<br />
<br />
إذا ترك المرض بدون علاج، تظهر المضاعفات، و هي مضاعفات سيئة جدا و هي لا تترك أي عضو في حاله.<br />
<br />
تتأثر العين بأشكال متعددة قد تصل إلى فقدان البصر في الحالات الشديدة. و يعد السكري السبب الأول لفقدان البصر في الدول المتقدمة. أيضا تتأثر الكلى بشدة لدرجة تصل إلى الفشل الكلوي.<br />
<br />
يزيد السكري من نسب حدوث تصلب الشرايين و ذلك يمهد الطريق لأمراض القلب المزمنة و ارتفاع ضغط الدم.<br />
<br />
واحدة من أهم  مضاعفات السكري هي زيادة إحتمالية حدوث الغنغرينا في القدم و لا تعالج إلا بالبتر. سبب ذلك هو تردي الإحساس في الأطراف بسبب تأثير زيادة الجلوكوز على الأعصاب. . عدم الإحساس يؤدي إلى جروح كثيرة في القدم مما يؤدي إلى انتقال العدوي بمختلف الميكروبات. أيضا تكون الدورة الدموية متباطأة و ذلك يمنع وصول خلايا المناعة للجرح الملوث و ينتهي ذلك بالغنغرينا و البتر.<br />
<br />
طبعا، نحن في غنى عن القول أن هذه المضاعفات سيئة للغاية لذلك يجب أن يحافظ مريض السكري على نظامه الدوائي و يحسنوا من أسلوب حياتهم. و الأفضل من ذلك هو الوقاية من المرض.<br />
<br />
يعد من السكري أكثر الأمراض التي لها علاقة وراثية حيث ينتشر المرض في عائلات بعينها و ذلك لأنه يتأثر بجينات بعيمها. لذلك عليك أن تأخذ حذرك أكثر إذا كان أحد أقربائك مصابين بالمرض.  <br />
يحث المرض كالتالي...شخص لديه جينات المرض و يعيش بطريقة غير صحية، لا يمارس الرياضة و يكثر من المشروبات الغازية و الأغذية الدهنية. يمثل ذلك عبئا على البنكرياس الذي يزيد من إفراز الإنسولين. هذا يسبب مقاومة الخلايا للإنسولين و يصبح كأنه غير موجود. إذا استمر الوضع لفترة طويلة، تُنهك خلايا البنكرياس و تتوقف عن إفراز أي إنسولين و يعتمد المريض على حقن الإنسولين مدى الحياة.<br />
<br />
يوجد حاليا دليل دامغ على أن اتباع حياة صحي يحمي الانسان من السكري حتى مع وجو الجينات المسببة للمرض.<br />
<br />
للإختصار:<br />
يمكنك أن تحمي نفسك باتباع اسلوب حياة صحي. مارس رياضة يوميا، أكثر من الخضروات و أقلل من المأكولات الدهنية و السكرية.<br />
اهتم بصحتك. لو لاحظت زيادة في معدل التبول بدون سبب ظاهر، يجب أن تستشير طبيب عن ذلك.<br />
لو كنت مصاب بالسكري عليك باتباع النظام الدوائي بانتظام لتقي نفسك من مضاعفات المرض.<br />
<br />

<br />
As we are approaching winter (in the Northern hemisphere), we are about to hear about people catching the flu. And of course with influenza being discussed, we all remember the Avian Flu that has scared the whole world in 2005 and early 2006.<br />
<br />
Let's first see what the word influenza means because it's interesting. The name comes from Italian and it means 'influence' because it was thought in the past that the disease was caused or "influenced" by stars. Anyway, the disease is caused by a virus and I guess everybody knows that. But why do you think you get influenza several times in your life and there's no such thing as permanent immunity against it? And why does the virus get monstrous sometimes and cause pandemics (appears in several countries simultaneously)?<br />
<br />
The answer to that lies in the unique structure that this organism has which enables it to shift and drift. But what does that mean?<br />
<br />
First let's see what "shifting" is but before that we need to know one thing or two about that virus.<br />
Each virus is an entity by itself, so it has to do its life on its own. Have you ever wondered how a virus can "see" its host from the trillions of other cells it comes across. Each virus 'sees' around by what's called receptors, and in case of influenza, the 2 important types are called H and N (of course!). These receptors are the sensors of any cell in all God's creatures and they act like eyes and ears (in humans an estimated 100,000,000 receptors on average are to be found on each cell!!). A close-up to the virus would look a ball with plenty of protrusion coming out of it.<br />
And the importance of presence of these receptor on a virus to the host, be it man, birds or any animal, is that they are what the immunity recognises and builds defenses against. (You can think of immunity's work as blinding the virus).<br />
<br />
So, what does that all mean? It has been found that receptor type H isn't one shape (about 15) and N too isn't (about 9) and the combination of one type of H and another of N makes a 'strain' of virus. Again, so what? Well, the virus has a very special feature that makes this work in a nasty way. Imagine that there's a bird that has flu from type H5N3. Nearby, there's a man who has flu from type H2N1. Neither of both can transmit its virus to the other species. Here comes the role of pigs. Sometimes they call pigs "mixing vessels" as they can catch the flu from both humans and birds and then the magic starts. Influenza virus (as all viruses and even bacteria) has small amount of genetic material, so typically, this amount just form a single lump in the middle of a virus or bacteria. But the flu isn't so. It kinda mimics higher animals by having its genes divided into 8 separate segments (as if they're chromosomes). And the very important part is that the gene for making H lies in a separate segment from that making N and this makes a problem!<br />
Let's get back to the pig thing we mentioned a while ago. So, a man has an "animal farm" where pigs are raised close to chicks. The man has H2N1 flu and the chick has H5N3. A pig catches the flu from both and viruses from both types infect the same cell (remember - mixing vessels). This all that should have happened to have H5N1 emerging as the rest of the process is completed by the normal life style of the virus. <br />
<br />
We said that a cell is infected by 2 types of flu. As we know, viruses get their genome inside a cell and starts dividing (refer to earlier posts in the group if you wish to know more about the life cycle). And each virus has 8 pieces of DNA so a sort of mix-up occurs and scientists have coined a name for that (and boy they like to do that) they called it "genetic reassortment". So after a mix-up happens new viruses emerge. And from the example we said we could get H5N1 or H2N3 or whatever other combination.<br />
This process is how pandemics occur in influenza. Every 20 or 30 years a new - completely new- strain comes up infecting thousands of people worldwide. And this is why it's called 'shifting' as if a virus is shifting to a whole new set of weapons. The last of these pandemics was the Avian Flu or H5N1 that emerged in Hong Kong in 1997. <br />
<br />
And now let's shift to drifting (which mean slow and gradual moving). The virus's genetic code has a feature that makes the code changeable. In almost all living things (except for few viruses) there are 2 copies of their code in each cell which preserves the code unchanged, but with influenza virus the case is different. There's only one copy in each virus. In addition, influenza viruses are lousy copiers, that's to say, they often make mistakes in copying their code during division or multiplication. "So what?", you say. "Their code gets distorted each time a virus divide, so they get weaker by the time, that's awesome!" In fact, the absolute opposite happens as they kinda change their skin (or weapons) so that they evade your immunity. So the nice work of your immunity during your last influenza infection gets useless as your are now virtually facing a new enemy. And from here comes the name, drifting..the virus always drift from its original shape to another for the sake of it livelihood. This drifting still enable the cell to recognise their preys but immunity does not which means you'll have to suffer from the flu till your immunity tailors a new plan to face the danger.<br />
<br />
Hope you enjoyed it!<br />

                    <title>Viruses…more about the damages</title> 
                    <link>http://www.tigblog.org/group/health/post/32927</link> 
                    <description><![CDATA[Today I'll be completing what I've started in my last blog in the group about viruses, their general characteristics and how they're harmful. It would be preferable that you have read the first blog as there will be several points in my talk today that depend on what was mentioned.<br />
<br />
Before getting to new stuff, I'd like to stress an important point regarding the structure of the coat covering the virus. I said that it could be a protein coat only or a protein coat and a fatty envelope. In either cases, this outer sheath be it the protein one or the fatty one, there are protrusions that appear on its surface. They're called surface receptors or surface 'antigens'. These are extremely important structures as they determine the type of cells the virus will attack. As I said they're like a key and the key hole is present on the surface of the attacked cells and the virus will only be able to invade a cell if it has the key that matches the cell key hole. <br />
These particles are also important because the cells of the attacked organisms will recognise that it's a virus through them and can tell exactly which virus it is and thus can elicit a proper immune response. Cells of humans, animals, plants, fungi...etc have similar structures that serve similar function.<br />
 <br />
Now we shall continue the answer of the question: how are viruses harmful?<br />
<br />
At the end of the previous blog we saw, generally, how viruses destroy their target cells. But now we shall see more specific examples of the viral damages:<br />
<br />
•	Viruses can inhibit the formation of protein and DNA in host cells which leads eventually to cell death<br />
<br />
•	Some viral proteins are inserted in the membrane of invaded cells which causes disruption of the membrane and consequently destruction of the whole cell<br />
<br />
•	These proteins that are inserted on host's cell membrane will make the cell seen by the immunity system as foreign and it will be attacked<br />
<br />
•	Viruses may cause damage to cells involved in antimicrobial defense thus paving the way to several infections. The classical example in HIV which depletes CD4+ cells which open the door for a hell of infections<br />
<br />
•	Virus killing of one cell type may lead to death of another type like in poliomyelitis where nerve cells are destroyed and thence muscle cells which aren't used at all die too<br />
<br />
•	A viruses can infect bacteria and doesn't form hundreds of copies of itself, but rather insert itself in the genome of the bacterium thus causing some characteristic changes in the bacterial cells. This causes harm in a remarkably interesting manner (of course interesting in an academic sense). An example will make this clear. Diphtheria bacteria are known to cause disease that could be fatal if untreated. The nasty effects of the infection are caused by a toxin the bacterium produces. It was found that only the bacteria that have viruses inserted in their genome secrete the toxin and the information for synthesizing that toxin is found on the genome of the inserted virus. Diphtheria bacteria that are virus-free  were found completely harmless<br />
<br />
•	CANCER<br />
<br />
Viruses are, almost, the only organism that has been found to have definitive role in the causation of cancer. The way through which they do so is mostly understood. <br />
The mechanism has some resemblance to what we have seen in the interaction between the diphtheria bacteria and viruses. Some types of human viruses, instead of taking the usual path and forming multiple of copies of themselves, they tend to insert themselves in the genome of the cell and settle their. In the bacteria, it wasn't a big deal and it didn't interfere with the host well-being. In case of human cells, the situation is completely different and this is logical because the human structure is radically different. Cells are governed by strict rules posed by the nervous system, hormones and many other local factors.<br />
Upon the insertion of the virus in the human cell genome, all these rules will be disobeyed. The cause is that the genome is a perfect code that guides a cell to its role and addition of foreign letters inside the code will disrupt it. So the affected cells obey no rules and divide endlessly leading to the infamous disease. It would be improper to say that any virus that takes this path will cause cancer. In some cases, the insertion of the viral genome amongst the human code causes intolerable changes that are incompetent with cell life. For a virus to cause cancer, it has to be implanted in very special sites that code for enzymes that regulate cell division and prevent cancer development. In such a case, the enzymes will be defective or not formed at all opening the gates for cancer.<br />
Few types of viruses have the ability to put themselves in these sites and they're known causes for cancer and here are some examples:<br />
<br />
1.	Human T-cell leukaemia virus type 1 (HTLV-1) which is associated with leukaemia/lymphoma<br />
<br />
2.	Human papilloma virus that has been implicated in the causation of squamous cell carcinoma of the cervix of uterus<br />
<br />
3.	Epstein-Barr Virus which has been described to be causative for some types of lymphomas…and there're other examples<br />
<br />
I think this is enough for now. In the next post we will see a very interesting issue; that is how the immunity reacts to viral infection. I hope to see some comments coz this means that someone has read the post!   <br />

                    <description><![CDATA[I'll be talking about viruses in this blog and may be one or two others to answer some of Cherry's questions and discuss other points too. Please feel free to comment on any thing you read in the blog.<br />
<br />
So what are viruses? The word "virus" itself is Latin and means poison.<br />
<br />
Viruses are ultra-microscopic micro-organisms, obligate intracellular parasites that can infect wide variety of living organisms starting from humans till bacteria. <br />
<br />
Size of virus:<br />
Viruses are measured in nanometres (a metre is a billion nanometres) and they vary from 20-400 nms. Bacteria, on the other hand, along with higher organisms' cells are measured in micrometres which is a millionth of a metre.<br />
In order to imagine the relative sizes of these cells you can say that a virus, a bacterium and a human cell put side by side are like a mouse, an elephant and a blue whale standing next to each others. (not very accurate but quite useful)<br />
<br />
This is regarding the size which makes viruses the smallest creatures known, and this isn't the only special thing about them, there're some other aspects and we'll see that as we talk about the structure of viruses.<br />
<br />
Viruses have very simple conformation. A typical virus or a "virion" will be containing:<br />
A- Genetic material, not a nucleus or chromosomes but a small piece of nucleic acid. In all living cells other than viruses, the genetic material is made exclusively of DNA and they posses similar molecules named RNA which are, very simply, like an apparatus reading the code written in DNA language and transforming it to usable information ( sure we will discuss their mechanisms in other times).<br />
In case of viruses, the genetic material could be made of DNA (like pox viruses) or RNA (like HIV)<br />
B- A Coat made of protein which is a shell carrying the genome. It has another feature that its surface isn't smooth but rather carry some particles with specific shapes that help them recognise similar structures on their target cell (like a key and a key hole).<br />
C- An Envelope made of fats and it isn't present in all viruses. Unlike what you might think the envelope doesn't give its viruses extra protection but it rather renders them more fragile as the fatty material of the envelope could be dissolved by any fat solvent like ether which leads to viral disruption. <br />
<br />
From the structure of the viruses we can deduce their important classifications. They could be classified as: enveloped and non-enveloped viruses by the virtue that not all viruses posses enveloped. Also they could be classified into: RNA and DNA viruses according to the type of their genetic material.<br />
<br />
There's another feature that is strange about viruses besides their very simple structure, very minute size and their peculiar genetic material. This feature is that a virus is only active inside living cells. That's to say, it doesn't perform any metabolism or multiply except inside cells and it's completely inert outside living cells. For instance, HIV (the virus causing AIDS) is transmitted from one to another carried inside white blood cells of the patient. This feature made some scientist call viruses semi-living aorganisms; that are only active iintracellular and are mere macro-protein particles outside living entities.<br />
<br />
One last question I shall discuss..how are viruses harmful?<br />
As we saw, viruses only exhibit life inside the cell of their victims. And what is their main goal? To make as many copies of itself as possible.. So a virus enters a cell be it a bacterium ,plant cell or whatever and uses all the resources, machinery and food of the cell to build hundreds or may be thousands of copies of itself which leads to depletion of the resources of a cell and its exhaustion. Now, the colony of viruses inside the cell can find no use of it so they destroy it to go outside and each one searches for another cell to build copies of itself and the cycle goes on and on... We can see one last peculiarity to viruses from their way of life. Their multiplication doesn't occur in the classical way as in animals or plants nor by simple fission as in bacteria and other unicellular creatures but rather by "replication".<br />
<br />
That's all for now. In the next time we will see how the invaded organisms interact with viruses, how viruses can cause cancer and may be one thing or two about influenza viruses. Again, please feel free to comment or ask about any thing that has been mentioned in the blog.  <br />
