Resistant HIV quickly hides in infants' cells

... those five, four were resistant to non-nucleoside reverse transcriptase inhibitors (NNRTIs), a common class of antiretroviral drug used to treat HIV infection and to prevent mother-to-child transmission. All had uncommon drug-resistance mutations that some resistance tests would miss. Earlier studies lo...

Technique monitors thousands of molecules simultaneously

...electrodes. "What electrochemistry does best is to reverse the polarity of things," Moeller said. "It takes things that are electron-poor and makes them electron-rich and vice versa; it can take an oxidant and turn it into a reductant; a reductant into an oxidant; a base into an acid and an acid into a base;...

Invasion of the island bats

...al independent bat groups, this article shows that reverse colonization is a feature of the entire Caribbean bat community, encompassing groups of bats as different from each other as aerial insectivores, nectarivores, and frugivores. The evolution of Caribbean bats suggests that far from being isolated ...

UCLA AIDS Institute researchers find a peptide that encourages HIV infection

Hives ferment a yeasty brew, attract beetle pest

...ood, reproduce and multiply. "If beekeepers can reverse the trend and eliminate the beetles, the hive can be saved," says Tumlinson. "If they can stop the beetles and remove eggs in the hive, the hive recovers." Honeybees are of major economic importance in agriculture as the major pollinating force for ...

NIH researchers discover protein that appears to regulate bone mass loss, the cause of osteoporosis

...deficiency of X-linked Hyper IgM Syndrome can also reverse the bone loss. If so, the knowledge gained from these studies may benefit people at risk of developing osteoporosis. ...

New success in engineering plant oils

...ts that the genetic manipulation could work in the reverse to allow scientists to engineer more heart-healthy food oils. "Scientists have known for a long time that the ratio of saturated to unsaturated fatty acids plays a key role in plants' ability to adapt to different climates, but to change this rati...

2 brains -- 1 thought

... its function. Memmesheimer and Timme now took the reverse perspective. "For some simple networks we know the activity dynamics, that is, their function, but not their exact structure," explains Memmesheimer. "Any given dynamics can normally be created by a variety of different networks. We have developed a ...

Glucose triggers brain cell death in rats after hypoglycemic coma

...ancisco. "It was only when we gave them glucose to reverse the hypoglycemia that the oxidative stress occurred. This was a real surprise." The researchers then discovered that oxidative stress and neuron death were prevented when the rats were given an inhibitor of NADPH oxidase, indicating a key role fo...

Study shows isolation of stem cells may lead to a treatment for hearing loss

... research is a major step in devising a therapy to reverse permanent hearing loss because it may lead to the activation of cochlear stem cells in the inner ear to regenerate new hair cells. “Clearly we have miles to go before we reach our end goal, but the exciting part is now we can test compounds that cou...

First-degree fetal heart block may be reversible

.... They also explored whether early treatment would reverse the problems. The team found that while first-degree fetal heart block may be reversible with the steroid drug dexamethasone, the condition could advance within as little as one week to a third-degree block, which is irreversible even with furthe...

Putting an old drug to a new use

...s frequently used to treat high blood pressure can reverse iron overload in mouse models and has the potential to treat similar conditions in humans. Our body needs most of its iron to make red blood cells. A lack of the metal can lead to dangerous anemias, but also too much iron can be detrimental as iron ...

Scripps research team discovers a chemical pathway that causes mice to overeat and gain weight
