Rhesus monkeys in Nepal may provide new alternative for HIV/AIDS research

...ny instances of local people seeking to solve this problem by chasing or killing macaques. "One of the goals of our international program is to assist our collaborators in creating the first primate research center in Nepal and to help address some of Nepal's most pressing health concerns that include HIV, ...

Genetic 'roadmap' charts links between drugs and human disease

...cular basis for such drugs' effects. To solve this problem systematically, the scientists described the effects of drugs and diseases in the common language of "genomic signatures," meaning the full complement of genes that the drugs turn on and off. To create a first-generation Connectivity Map, the scie...

MRSA vaccine shows promise in mouse study

...lococcus aureus (MRSA) infections have long been a problem in hospitals, nursing homes and dialysis centers, more and more healthy people with no apparent risk factors have been turning up in emergency rooms with virulent S. aureus infections acquired from community rather than health care related sources. ...

Electric fish in Africa could be example of evolution in action

...ible," Arnegard said. "But it could be a detection problem because speciation occurs over so many generations." These Gabon fishes' impulses, however, can change very quickly in comparison. So Arnegard suspects that the different shapes of the electric impulses from these mormyrids might be a first step in s...

The secret lives of sea slugs

Tests may help answer questions about GMOs and allergies

...rotein cause an allergic reaction in animals?' The problem is that there has been no good animal model available to test this." Gangur and students in his lab have developed a mouse model ?the first of its kind ?to test the allergy-causing potential of genetically engineered foods. He'll use the EPA grant t...

New study reveals structure of E. coli multidrug transporter protein

The study is being published in ScienceXpress, an advance online edition of the journal Science, on May 5. "The development of antibiotics to treat infectious disease is b...

Newborn screening can cause unnecessary parental stress

... they were told they wouldn't be notified unless a problem was found, and 24 percent were required to ask their pediatrician for the test results. "A few parents didn't even know they'd had a repeat test," Waisbren says. Sixty-one percent of parents felt a need for more information about newborn screening...

Orange, grapefruit juice for breakfast builds bones in rats

...rone is known to reduce antioxidants. "This is a problem with aging men, because, the level of testosterone decreases as men age," said Deyhim, adding a similar study on female rats has begun. Deyhim said fresh grapefruit or orange juice - mixed with sodium bicarbonate to neutralize acidity - was given to...

...is region and serve an important purpose." The problem now, he said, is any resistance breaks down in high temperatures. And not enough is known about the wheat curl mite to tellproducers when or what to spray. "There are big gaps in our knowledge," Rush said. "But we are making progress and have thi...

Producing bio-ethanol from agricultural waste a step closer

...petition with food supplies. Until recently, the problem was that the complex mixture of sugars that makes up these leftover materials could not be efficiently converted into ethanol by the baker's yeast. Delft University of Technology, however, has recently devised a solution for this, which is achieved b...

K-Staters design and build a low-cost remote sensing tool for environmental studies

...the pens at a feedlot; or checking crop fields for problem areas, for example. "We keep thinking of new civilian uses for it," Ham said. He also said it will help his own research, which focuses on measuring the movement of gases between the prairie and the atmosphere. Ham collects data via a mini-network ...

Diabetes research takes wing thanks to long-lived fruit fly

.... "It's a huge health issue. Many people have this problem ?it's not going away anytime soon. "This research isn't so much about making people to live to 120 as it is about preventing diseases like diabetes, heart disease, or Alzheimer's. We're trying to identify the mechanisms that cause damage to our body...

Bone marrow may restore cells lost in vision diseases

...ors like smoking and diet also come into play. The problem is without these cells, the rods and cones - our primary cells for vision - die. If we can regenerate the retinal pigment epithelium, it could make a big difference in our visual health." Scientists were able to detect that RPE cells indeed appear t...

Drug dials down the energy within cells, UM researchers find

...yme, there might be therapeutic potential. But the problem is, if you inhibit the enzyme in the way most powerful drugs do, turning it off, you deplete the cell of ATP, and that's fatal," Glick said. "Our new work reveals the mechanism by which Bz-423 inhibits the enzyme while still allowing it to function. ...

New treatment for food poisoning

...s work brings some optimism to the highly worrying problem of the increasing resistance to antibiotics." The Listeria bacteria causes the food-borne disease, listeriosis. It often triggers a brain infection and kills up to 30% of those affected. To test whether antibiotics are effective, bacteria are take...

Mice learn tasks that may help treat human psychiatric disorders
