Scratch no more: Gene for itch sensation discovered

...ified the first gene for the itch sensation in the central nervous system. The discovery could rapidly lead t... a receptor specific for the itch sensation in the central nervous system. The findings are reported this week in Nature through advance online publication. C...

Identified main genetic variants involved in response to HIV

...mitted to deduct main genetic variations playing a central role in the control of viral infection. Results point to two gene variants related to the immune system. More precisely, these variations are in a genetic region responsible for the determination of immune response capacity against a number of infe...

Undergraduate research shows leaderless honeybee organizing

...direct and coordinate complex operations without a central controlling intelligence. Pierce’s finding is part of an ongoing research effort in Schneider’s lab aimed at understanding the mechanisms of leaderless societal management – in particular, the importance of two communication-related behaviors known ...

Progress toward an antitumor vaccine

...anes. They are glycoproteins—macromolecules with a central protein chain and long side chains made of polysaccharides. The modified MUC1 would be a good target molecule (antigen) for antibodies in immunological antitumor therapy. The difficulty with this approach is that such sugar-containing compounds ar...

UCF nanoparticle offers promise for treating glaucoma

...e activity of an enzyme (hCAII) believed to play a central role in causing glaucoma. The disease involves abnormally high pressure of the fluid inside the eye, which, if left untreated, can result in damage to the optic nerve and vision loss. High pressure occurs, in part, because of a buildup of carbon ...

Researchers identify protein pathway involved in Parkinson disease development

...arkinson disease is a degenerative disorder of the central nervous system resulting from the loss of neurons in the brain that produce dopamine. This lowering of dopamine leads to decreased stimulation of the brain's motor cortex. Although scientists have not known the exact cause of the loss of these dopa...

Surprising origin of cell's internal highways

...e distant tissues. Because microtubules play a central role in cell division, cancer drugs like colchicine, vincristine and paclitaxel (Taxol) can block cell division by altering microtubule dynamics. "Many classic chemotherapy strategies affect microtubules, although it's not quite clear how these d...

Experimental gene therapy 'abolishes' arthritis pain and lessens joint damage

...hat arthritis in one joint can spread, through the central nervous system (CNS), to other joints. Worse yet, joint arthritis may export inflammation to the brain, where it plays a role in neurological conditions (e.g. Alzheimer’s disease, dementia and multiple sclerosis). While the just published study ...

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

Does amateur boxing cause brain damage?

...d hits to the head are potentially damaging to the central nervous system, and our results suggest CSF-analysis could be used for medical counseling of athletes after boxing or head injury," said Hietala. The study was extended to soccer players heading the ball repeatedly from long and high goal kicks. N...

Climate change impacts stream life

... Now a twenty-five year study at Llyn Brianne in central Wales, led by Professor Steve Ormerod and Dr Isabelle Durance of the Cardiff School of Biosciences, has examined for the first time the effects of climate change on stream species. The study looked at the effects of climate change on stream mac...

Diminishing dinosaur steps saved by laser and laptop

The Fumanya site, in the Bergueda region of central Catalonia, is so delicate that experts cannot get physically close enough to the tracks to examine them. In the years since the tracks were discovered they have been exposed to the elements, and as a result are severely weathered and eroding at a ra...

'Short-circuit' found in ocean circulation

...d nutrients around the globe and therefore plays a central role in regulating Earth's climate. The findings show that much of the overturning circulation - how water moves and mixes vertically - around Antarctica takes place just around the tip of South America and in the small region in the Atlantic sou...

Sleepless for science: Flies show link between sleep, immune system in Stanford study

...y for sure say whether a disruption of the brain's central clock, which is the area of the fly brain that exhibits circadian gene activity, was responsible for the changes seen in the sick flies. But the behavior of the ill flies looked a lot like that of flies known to have disruptions in their genes contro...

Herpes infection may be symbiotic, help beat back some bacteria

...a minor cause of food poisoning and can infect the central nervous system. Many aspects of Listeria infection in mice are also similar to those that occur in humans infected with tuberculsis. They found that when mice had a latent herpes infection, the bacteria replicated more slowly and were less likely to ...

Revealing the machinery underlying the 'plastic' juvenile brain

Among the central mysteries of neurobiology is what properties of th... differences in genetic activity that appear to be central to this plasticity. Tommaso Pizzorusso and colleagues published their findings in the March 1, 20...

Proteasome activator enhances survival of Huntington's disease neuronal model cells

...arily of huntingtin. One cellular organelle with a central role of clearing such protein build up in the cell is the ubiquitin proteasome system (UPS). In Huntington's disease (HD) brains and other tissues, UPS activity is inhibited and intraneuronal nuclear protein aggregates of mutant huntingtin in HD bra...

In Iran, cheetahs collared for the first time

...Area, Yazd Province, in the south-west area of the central Iranian plateau, where they were tranquilized, and fitted with compact GPS collars weighing 350 grams- only 1% of the cheetahs' weight. It is the first time the species has been handled by a scientific team in Iran and represents a unique new phase ...
