...he virus that causes AIDS, fails. The test, which detects genetic changes, or mutations, in HIV, also may help scientists understand how the constantly evolving virus develops drug resistance, Gao said. He said such knowledge ultimately may result in the development of new treatments designed to evade resis...Small molecule offers big hope against cancer
...sts like PET (positron emission tomography), which detects the unique metabolic profile of cancer compared to normal cells," added Michelakis, the Canada Research Chair in Pulmonary Hypertension. Another encouraging thing about DCA is that, being so small, it is easily absorbed in the body, and, after oral ...New miniaturized device for lab-on-a-chip separations
...ts begin to move. A sensor placed over the channel detects each new component as it arrives, GEMBE is ideally suited for use in microfluidic "lab-on-a-chip" devices. Components are selected by buffer flow-rate rather than distance, so the channel can be very short--less than a centimeter in NIST prototypes...Male sweat boosts women's hormone levels
...nose resembling the vomeronasal organ in rats that detects pheromones, it appears to be vestigial, with no nerve connection to the brain.

When AMPK detects low levels of ATP in the cell, it works through a different mechanism to increase how much glucose the cell takes in and uses to create ATP. Research in rodent models has shown that AMPK activators can lessen the pathologies associated with diabetes......ost, SCP-MAC utilizes 'low-power listening,' which detects channel activity very quickly.

Southwick's team used an unusual approach to tease out the anthrax toxin's effects on cell migration: They allowed the immune cells to be hijacked by another bacterium, Listeria ...Blood test may help signal tumor's remission, return in throat cancer patients
A blood test that detects proteins commonly released by a growing tumor could one day become a useful tool for monitoring the effectiveness of chemotherapy and radiation treatment in people with advanced throat cancer, according to a study published in the June 1, 2007, issue...Menthol receptor also important in detecting cold temperatures
