Genomic Analysis Uncovers New Targets for HIV Vaccine

...r HIV vaccines. In the new analysis, patients with specific gene variants in key immune system cells appear to be much better at controlling the proliferation of the virus after infection. These gene variants are known as polymorphisms. "These results not only approximately double our understanding of the fa...

Scratch no more: Gene for itch sensation discovered

...itching, offering the first evidence of a receptor specific for the itch sensation in the central nervous system. The findings are reported this week in Nature through advance online publication. Chronic itching is a widespread problem. It can be caused by skin disorders like eczema, or it can stem from a de...

Innovative smallpox vaccine research study to be conducted at Case Medical Center

...e face and body of an infected person. There is no specific treatment for smallpox disease, and the only prevention is vaccination. The World Health Organization declared the disease eradicated in 1980 with the success of a worldwide vaccination program. Routine vaccination against smallpox among the general ...

Cigarette smoke alters DNA in sperm, genetic damage could pass to offspring

...ither six or 12 weeks to look for alterations in a specific stretch of repeated portions of DNA, called Ms6-hm, which does not contain any known genes. The “smoking” mice were exposed to two cigarettes per day, the equivalent – based on blood levels of tobacco by-products – of an average human smoker, accordi...

New study reports hotel guests at risk from carbon monoxide poisoning

...risk in that industry. The AH&LA study made no specific recommendations regarding prevention of CO poisoning to guests, and concluded, ‘AH&LA will continue to monitor industry-related carbon monoxide issues.’ Until CO alarms are installed in hotels, motels, and resorts, guests should consider carrying...

Hormone helps mice 'hibernate,' survive starvation

...bolism. FGF21, triggered in starving mice by a specific cellular receptor that controls the use of fat as energy, spurs a metabolic shift to burning stored fats instead of carbohydrates and induces a hibernation-like state of decreased body temperature and physical activity, all geared to promote survival...

Research team identifies new Alzheimer's gene

...pace by enabling scientists to better identify the specific genetic variations associated with complex diseases,” said Kevin King, President of Life Sciences Business and Executive Vice President at Affymetrix. In addition to surveying an unprecedented number of genetic markers in each person’s DNA, the re...

Loss of stem cells correlates with premature aging in animal study

... to renew itself, most tissues have a reservoir of specific adult stem cells. These stem cells don’t divide as frequently as other cell types since they need to maintain the integrity of their DNA, and multiple divisions lead to natural breaks in DNA. But when these stem cells are needed, their progeny can ra...

Pesticides choke pathway for nature to produce nitrogen for crops

...hat agrichemicals bind to and block connections to specific receptors (NodD) inside rhizobia bacteria living in root nodules in the soil. Rotation legume crops such as alfalfa and soybeans require such interaction to naturally replace nitrogen levels that, in turn, benefit primary market crops like corn grown...

Study shows big power of small RNAs, not just proteins, in halting cancer

...tween changes in the p53 pathway and the loss of a specific family of miRNAs, known as miR-34. The fact that p53 uses miRNAs to stop tumor cell growth reveals a completely new dimension of this critical cancer fighting pathway and its ability to trigger the genetic death of cancer cells. “Our findings cert...

Columbine flowers develop long nectar spurs in response to pollinators

... a stop-and-go pattern--one in which adaptation to specific pollinators occurs very rapidly, followed by periods of no further evolution until another pollinator shift occurs, according to William Zamer, deputy director of NSF's division of integrative organismal systems. "In the case of these flowers, cha...

New study finds genetically engineered crops could play a role in sustainable agriculture

...antages or disadvantages of GM crops depend on the specific goals and vision for agroecosystems. As NCEAS Director, Jim Reichman explains, “This important study by an interdisciplinary research team reveals how an in-depth analysis of large quantities of existing data from many individual experiments can...

Newly found sensing system enables certain bacteria to resist human immune defenses

...phylococcus epidermidis to study its response to a specific human AMP, human beta defensin 3. S. epidermidis is one of several hard-to-treat infectious agents that can be transmitted to patients in hospitals via contaminated medical implants. Findings by Dr. Otto’s research group are published in the May 29 i...

Brightening prospects of using fluorescent nanotubes in medical applications

An example of the possible medical applications of nanotube fluorescence is a collaboration that Hertel and Associate Professor of Biom...

New collaborative research reveals chimpanzees can sustain multiple-tradition cultures

In this study, members of the international collaborative research team taught forms of tool use and food extraction techniques...

Sun exposure early in life linked to specific skin cancer gene mutation

Researchers interviewed 214 melanoma patients in North Carolina about their risk factors for melanoma and about the various places they had lived. Each patient's UV sun exposure was estimated from their residential history a...

All in all its an exciting time for eye research and a very promising one for people with these conditions. This new result is another important step in the right direction and Yorkshire Eye Research is ve...

U-M researchers discover gene switched off in cancer can be turned on
