Stem cells bring fast direct improvement, without differentiation, in acute renal failure

...pe after being cultured, the researchers routinely tested whether their characteristic potential to differentiate into fat and bone cells was preserved. The researchers conceded that it "is surprising that the very transient presence of MSC in the injured kidney, as we document, is sufficient to greatly am...

Gene for immune deficiency syndromes found

...nts with IgA deficiency. None of 50 healthy people tested had a TACI mutation. Four of the 5 patients with TACI mutations were studied further, and all 4 had relatives with the same mutations. Eleven of the 12 identified relatives with TACI or IgA deficiency reported a history of recurrent infections and we...

Researchers Create DNA-Based Sensors for Nano-Tongues and Nano-Noses

... on New Years' Eve. In the report, the researchers tested the nanosensors on five different chemical odorants, including methanol and dinitrotoluene, or DNT, a common chemical that is also frequently a component of military-grade explosives. The nanosensors could sniff molecules out of the air or taste them...

Computers close in on protein structure prediction

...es, such as a mouse or fly. The protocol was first tested on a blind annual prediction test considered to be the highest standard for removing bias from protein structure prediction models. "We can't compute the energies perfectly, but the biggest problem is the search through possible shapes," Baker said....

Computer modeling reveals hidden conversations within cells

...As they were developing the model, they repeatedly tested and refined it by comparing the model's predictions with the results of experiments with living cells. "The beauty of this kind of interdisciplinary work is the almost circular way the model's predictions drive the design of new experiments, and the...

How HIV disables the cells' call for help

...diseases? To check their theory, the research team tested FP on rats suffering from an autoimmune syndrome similar to human rheumatoid arthritis, and on cultured human T cells. As they predicted, the rats treated with FP showed a significant reduction in joint swelling and other symptoms of arthritis. Shai...

Study charts origins of fear

...found they were less hesitant to avoid shocks. "We tested the animals using both spatial and auditory cues," Zhuo says. "In one experiment, the mice received small shocks when entering a chamber and they developed fear memory. In another experiment, we used sound tones to be associated with shocks. When NR2...

Molecular mechanism of feather formation found

...ing of barbs in feather development. The team then tested whether such interactions truly exist in the developing feather. In the first steps of feather development, cells exposed to essentially the same levels of Bmp2 and Shh grow from a small bud to form a uniform ring. Shh then is expressed in specific s...

Breast tumors in mice eradicated using cancer vaccine

...e very excited to see the technology finally being tested in cancer patients. The dream of the cancer immunotherapist is to provide an alternative and more humane way of controlling metastatic disease than current chemotherapies." The Listeria vector is currently being prepared for a clinical trial targeti...

Exercise aside, genes may ultimately dictate seniors' mobility

... a quarter mile or up 10 stairs. Researchers also tested the blood of each study subject to identify which version of a gene long associated with exercise performance they had. About a third of the population possesses the DD genotype of the gene, named for the angiotensin-converting enzyme, or ACE. The re...

LIAI scientists make major finding on potential smallpox treatment

...he smallpox virus," he said. The researchers then tested their findings by creating a batch of the anti-H3 protein antibodies, which they injected into mice. "We were able to protect them from a strain of vaccinia pox virus that is very similar to smallpox and which is lethal to mice." The National Insti...

Hurricane aftermath: Infectious disease threats from common, not exotic, diseases

...rinking only bottled water unless authorities have tested the water now being piped into some facilities and have declared it safe to drink," says Berkelman. "To also prevent risk of infection, people should practice basic hygiene, frequently washing their hands with soap and clean water or disinfecting ha...

Experimental shingles vaccine proves effective in nationwide study

... researchers emphasize that the zoster vaccine was tested only as a preventive therapy and is not intended as a treatment for those who already have shingles or postherpetic neuralgia. On April 25, Merck announced that it had submitted a license application to the Food and Drug Administration for the zoster...

Survey Uncovers Surprising Attitudes Towards HIV Vaccine Research

...her or incorrectly believe that the vaccines being tested can cause HIV infection. Only 24 percent of the general population responded comparably. * Among men who have sex with men, 77 percent cited HIV/AIDS as the most urgent health problem. Only a small percentage of the other groups surveyed, however...
