Genomic Analysis Uncovers New Targets for HIV Vaccine

... levels off, a period during which patients do not exhibit symptoms of their disease. The viral load during this leveling out is an indication of how well the patients' own immune system is battling the virus, and this is the point in the infection's natural history that the researchers studied. The CHAVI i...

Art and music for the birds

...gh Wednesday, Nov. 21. Visitors of the interactive exhibit receive a schedule of songs emitting from each station, which will repeat approximately five songs each. Birds can tune in to classics like Vivaldi’s “Concert in D Major,” Miles Davis’s “Blue and Green,” and Led Zepplin’s “Kasmir.” They may also he...

Blood test may help signal tumor's remission, return in throat cancer patients

...ge increases in protein levels were more likely to exhibit a return of the cancer or to die from it. For example, large increases in IL-6, VEGF, and HGF concentrations over time yielded a 3.8-fold, 3.0-fold, and 2.9-fold higher risk of dying of throat cancer, respectively. Patients with an increase in three ...

Dual-imaging technique useful before -- and during -- brain surgery

... this preliminary research in a special scientific exhibit at the American Society of Neuroradiology’s annual meeting, June 9–13 in Chicago. To combine both functional MRI and diffusion tensor tractography images in the operating room, Leach and his colleagues use a high-tech surgical navigation system k...

University of Pittsburgh School of Medicine researchers develop 'off-the-shelf' vascular grafts

Puzzling plankton yield secrets to role in evolution/global photosynthesis

...synthetic activity. These "picophytoplankton" also exhibit great diversity that contrasts sharply with the dearth of ecological niches available to them in aquatic ecosystems. This observation, known as the "paradox of the plankton," has long puzzled biologists. Plumbing the depths of molecular-level inf...

Cornell lab confirms deadly fish virus spreading to new species

...ehaves abnormally. Not all infected fish, however, exhibit symptoms. Some may be carriers, and visible signs of the disease may vary from species to species. Containing the spread of the virus in New York will require restrictions on the movement of live fish, testing fish and surveillance. For instance, ...

Flies don't buzz about aimlessly!

The next step will be toward integrating these results with the neurobiology of fly flight to better understand how these tiny animals are so successful at crashing our dinner parties. The research will appear in the April 4th...

Researchers identify gene involved in dog size

... breeding by humans throughout history, dogs today exhibit an extremely wide range of body types and behaviors. In fact, dogs exhibit the greatest diversity in body size of any mammalian species. In their study, researchers explore...

Study shows hope for early diagnosis of Alzheimer's

...eople with dementia, particularly Alzheimer’s, may exhibit that peak much later than 300 milliseconds, show a much weaker peak or have no peak at all, according to Polikar. Kounios said the P300 signal is generated by areas of the brain that seem to be attacked at an early phase of Alzheimer’s disease, but t...

Ancient amphibians evolved a bite before migrating to dry land

...likely deformed as the animals ate. Living fish exhibit an incredible array of tooth and jaw shapes, suggesting that, ironically, direct analysis of fossil jaws would be a less precise means of determining the feeding methods of extinct species, Markey says. "Analysis of the sutures of the early amphi...

New cell type identified in cancer development

...markers most of the cancer cells had, but they did exhibit stem-like structure. The researchers suspected these unusual cells might be precancerous stems cells and designed several tests and experiments to find out more about them. They selected three pCSC lines and injected them subcutaneously, intraper...

Gene that makes people 'early to bed and early to rise' demystified

...hat it takes just one copy of the abnormal gene to exhibit symptoms. The UCSF group had earlier discovered a variant of the human Per2 gene that causes FASPS. They also showed that the so-called "S662G" variant, in which the serine building block normally present at position 662 is replaced by glycine, pre...

However, the standard treatments for ADHD -- Ritalin and other stimulants -- are not always effective in these children. Studying the effect...

Erectile dysfunction in diabetes is due to selective defect in the brain

...zotocin (STZ) to induce diabetes were used as they exhibit sexual and behavioral symptoms similar to those found in diabetic men with sexual dysfunction. The researchers focused on the paraventricular nucleus (PVN) of the hypothalamus, located in the brain, an integration center between the central and p...

Parasite infection may benefit MS patients

...lanation for the mechanism by which infected hosts exhibit an altered immune response that affects a secondary antigen, as was the case in the current study. "Thus, parasites may lead to increased regulatory T cell numbers or activity, either by generating new cells or by activating/expanding existing cells,...

Drug treatment improves learning in mice with Down syndrome symptoms, Stanford/Packard study shows

Fernandez gave low daily doses of PTZ and investigated the animals?responses to unfamiliar objects and a T-shaped maze. In the first example, he allowed the animals to explo...

Scientists identify a candidate gene for osteoporosis
