The mChip, as it is called, is the size of a credit card and replicates all steps of an ELISA test, at a lower total material cost and within 20 minutes. After application of a blood sample, the chip is inserted into a $100 battery-powered handheld analyzer. It needs only 1 μl of unprocessed whole blood and does not require any user interpretation of the signal, providing a clear-cut yes or no result. Right now, HIV testing in developing countries either relies on expensive laboratory testing taking a long time, or uses cheaper methods based on lateral flow, which, although very rapid, do not provide very reli...

It is estimated that 50 to 100 million people in more than 100 countries are infected each year with dengue viruses. There are four different types of dengue virus, and there is no cross-immunity, so a person may be stricken with dengue fever four times in his life. The most active feeding times for dengue vector mosquitoes is for a few hours after daybreak and in the afternoon for a few hours just after dark (dusk). As opposed to the night-feeding mosquitoes that transmit malaria, these species tend to be “urban,” may also feed during daylight hours (also indoors, in the shade, and during overcast weather), and are known to bite below the waist. Dengue fever is seen chiefly in...

This method, which does not require fractionation of the sample by gel electrophoresisis, is based on the property of proteins to readily bind to a plastic surface. To detect viral proteins in serum or clinical samples, a capture antibody, directed against the protein, is linked to a solid support such as a plastic 96 well microtiter plate, or a bead. The clinical specimen is added, and if viral antigens are present, they will be captured by the bound antibody. The bound viral antigen is then detected by using a second antibody linked to an enzyme. A chromogenic molecule – one that is converted by the enzyme to an easily ... virology blog blogs http://www.medworm.com/rss/comments.php?id=3946234 Fri, 16 Jul 2010 16:28:49 +0100 3946234 http://www.medworm.com/index.php?rid=2970436&cid=t_104928_167_f&fid=38271&url=http%3A%2F%2Frebeccascritchfield.wordpress.com%2F2009%2F11%2F07%2Fyou-can-count-on-nutrition-at-your-fingertips-for-food-advice%2F Everybody eats.

Recently I met this guy I really like. It’s nothing like dating or relationship, more like a sexual friendship, a step up from f.buddy, but a step down from dating. Something in between in that no strings kind of connection. He is negative, and in the past has taken such extreme risks. Today he sent me a text from Hassle Free Clinic to say his test came back negative. Since we’ve met, despite his avserion to condoms, nonetheless, we have used them everytime time. After having posted a sure to be controverial post on GayGuideToronto.Com last week about guys having condomless sex, with a few sites targeting those guys, I want to make it clear I am not into bar... acidrefluxweb.com blogs http://www.medworm.com/rss/comments.php?id=2890884 Tue, 13 Oct 2009 16:19:37 +0100 2890884 http://www.medworm.com/index.php?rid=486670&cid=t_104928_105_f&fid=35048&url=http%3A%2F%2Ffeeds.feedburner.com%2F%7Er%2FMedicineAndMan%2F%7E3%2F42826835%2F I recently saw a patient who came in for follow up after being treated for sexually transmitted disease. He wanted copies of his medical records - more importantly he wanted a copy of his HIV status!! This guy who I will call Mr. X had had multiple sexual partners in the past few months and wanted the HIV medical report because he was HIV negative. On inquiring, Mr. X revealed that he wanted to “prove” to his girl friends that he was HIV negative so that he could have unprotected intercourse. I spent about 1 hour explaining to him the limitations of the HIV test and his chances of re-infection after unprotected sex. I hope he understood. This encounter set me thinking. How many people are there in the world who use the “No HIV certificate” as proof of not having AIDS and thus runn...
