Scratch no more: Gene for itch sensation discovered

...n given itchy stimuli. The laboratory experiments confirmed the connection between GRPR and 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 ...

Cellular message movement captured on video

...eton. Even without video evidence, scientists have confirmed over the past 10 years that higher organisms use paxillin as a transmitter of locomotion and gene-expression signals from several classes of growth-factor receptors to the nucleus. Cancer researchers are eager to understand paxillin’s many interac...

Research team identifies new Alzheimer's gene

...ce, the study included more than 1000 brain donors confirmed to either have Alzheimer’s disease or be free of the disorder at autopsy. This study resulted in a comprehensive set of high-quality data to be made publicly available to the research community. The researchers believe that deposition of this data se...

Massive herds of animals found to still exist in Southern Sudan

...1 and 2002 of the wildlife populations in Boma and confirmed the presence of white-eared kob in considerable numbers. At the time, aerial surveys could not be conducted due to the ongoing war. “We were amazed to see these large numbers of white-eared kob in Southern Sudan,” said Marjan. “Most people assumed we...

First confirmed common genetic risk factors for breast cancer

...cancer research, because these genes are the first confirmed common genetic risk factors for breast cancer," said Dr. Liu. As common genetic risk factors, these genes likely have more impact than the previously identified risk genes on disease prevalence across a large population of women. However, Dr. Liu ...

Detecting cold, feeling pain: Study reveals why menthol feels fresh

...ned this theory. In the current study, the team confirmed their hypothesis by "knocking out" the gene that synthesizes the receptor, both in sensory neurons in cell culture and in mice. The cells in culture were unresponsive to cooling agents, including menthol. The genetically engineered mice did not discr...

Statin treatment improves spatial memory in mouse models of Alzheimer's

...cology and Experimental Therapeutics. The study confirmed the Morcos laboratory’s earlier findings of improved memory in this mouse model of Alzheimer’s and discovered new information about the neurochemical basis of the beneficial effects. Various studies have found evidence of a strong relationship betwee...

Early exposure to indoor fungus molecules may protect infants against future allergies

...at the University of Cincinnati (UC) say they have confirmed what other scientists have only suspected: early-life exposure to certain indoor fungal components (molecules) can help build stronger immune systems, and may protect against future allergies. The UC team found that infants who were exposed to hig...

'Personality-gene' makes songbirds curious

... The results from the group of selected birds were confirmed with data from free-living, unselected great tits. In the forest-living birds, the scientists also found a significant association between the SNP830-genotypes of individuals and variation in their level of curiosity. "The personality trait can be...

Global survey of lizards reveals greater abundance of animals on islands than on mainland ecosystems

... survey of lizards on islands around the world has confirmed what island biologists and seafaring explorers hav...igh densities. In their study, Jetz and Buckley confirmed that reduced numbers of predators and competitors accompany high lizard densities on islands across ...

Nitric oxide: Key to cardiovascular and pulmonary function and drug effectiveness

... drugs. The researchers said these findings, if confirmed in humans, open up new avenues for the development of non-desensitizing drugs not only for heart failure and asthma but also for other conditions such as pain and high blood pressure. "We demonstrated that when one of the systems goes awry, so doe...

Maggots rid patients of MRSA

...iminate MRSA infection of diabetic foot ulcers. If confirmed in a randomized controlled trial, larval treatment would offer the first non-invasive and risk-free treatment of this increasing problem and a safe and cost-effective treatment in contrast to the expensive and potentially toxic antibiotic remedies." ...

New Brandeis research sheds light on memory by erasing it

...lead author John Lisman. "With this study, we have confirmed CaMKII as a memory molecule." The research involved electrically stimulating neuronal synapses to strengthen them, a process known as long-term potentiation (LTP). This process has served as a model system for studying memory. CaMKII has been a le...

New bacteria test could improve quality of fruit and vegetable juice

...cult to distinguish visibly until test results are confirmed or after juice products have been opened and tasted by consumers. In addition to agitating taste buds, the latter can affect consumer confidence. Lin's technique is significant because it identifies the organism quickly ?in a matter of...

WHO data confirms low level of resistance to Tamiflu

...blished by the World Health Organisation (WHO) has confirmed a low frequency of resistance to Tamiflu (oseltamivir) over 3 influenza seasons (2003 ?2006)1. The information, published by the Neuraminidase Inhibitor Susceptibility Network in the WHO’s Weekly Epidemiological Record, has shown that resistance ...

Parasites' impact goes beyond host to affect ecosystem

...ould also be prevalent. A laboratory experiment confirmed Wood’s and Byers?hypothesis: snails infected with the parasite ate 40 percent less macroalgae than uninfected snails. In the field, where researchers measured the macroalgae in three types of bottomless cages -- with no snails (control), uninfected s...

The quest for an effective HIV vaccine presents new possibilities, challenges

...r immunity. Numerous animal and human studies have confirmed how important cellular immunity is in the early and later stages of HIV infection, even though the virus is never completely eliminated. Vaccines that induce strong cellular immune responses may have some benefits, say the authors. In non-human prima...

Growing nerve cells in 3-D dramatically affects gene expression

...cifically linked to cell growth. Those experiments confirmed the differences in gene activity. Hoffman-Kim and her team deployed high-powered microscopes to detect other differences. Cells cultured in 3-D had a rounder, more realistic shape, and their neurites ?spindly projections sprouting from the cell bo...

Discovery of new cave millipedes casts light on Arizona cave ecology

... this new genus of cave-limited millipede has been confirmed by Bill Shear, a leading millipede expert at Hampd...orthern Arizona University." This new genus was confirmed by analysis of the eighth pair of legs (or gonopods) on the male specimens. Gonopods are highly modi...

Brain's reward circuit activity ebbs and flows with a woman's hormonal cycle

...the post-ovulatory phase. The researchers also confirmed that the reward-related brain activity was directly linked to levels of sex hormones. Activity in the amygdala and hippocampus was in lockstep with estrogen levels regardless of cycle phase; activity in these areas was also triggered by progesterone ...
