'Nanospheres' that block pain of sensitive teeth

...article for filling these channels and reducing or preventing the pain caused by sensitive teeth". The next stage of their research will be to work out how to synthesize nanospheres of hydroyapatite or a combination of hydroxyapatite and fluorine which would fill the holes and encourage re-mineralization at th...

Natural compound from 'pond scum' shows potential activity against Alzheimer's

...rase inhibitors have shown promise for delaying or preventing the symptoms of mild to moderate forms of the disease, experts say. The newly isolated compound, nostocarboline, was shown to be a potent inhibitor of cholinesterase -- a brain chemical thought to be important for memory and thinking -- whose breakdo...

Researchers identify molecular anchor that allows bacterial invasion of central nervous system

... surface could become new a therapeutic target for preventing bacterial meningitis." Doran and Nizet noted that the study focused on how bacteria can begin the invasion process, and that additional Streptococcus toxins and the body's own immune response also contribute to the development of meningitis. In the...

Scientists determine structure of enzyme that disrupts bacterial virulence

...onal structure of an enzyme that may be pivotal in preventing certain bacterial infections in plants, animals and humans, according to a study published in the Proceedings of the National Academy of Sciences. The enzyme had already been shown in previous studies to significantly decrease soft rot in potato pl...

Anti-cancer drugs may hold promise for premature aging disorder

...suspected, it enmeshed other scaffolding proteins, preventing their proper integration into the lamina. If progerin's tendency to stick to the inner nuclear membrane is indeed the culprit in nuclear blebbing and the root of the progeria defect, Capell and his colleagues reasoned that they could prevent these de...

New study expands understanding of the role of RNA editing in gene control

...atopoietic tissues. This editing had the effect of preventing a key miRNA processing enzyme called Drosha from cutting the precursor miRNA molecule at a critical step in that process. Looking downstream along the miRNA processing pathway, the scientists also discovered that a molecular complex called RISC play...

New technique multiplies life span in simple organisms

..., Longo is studying the feasibility of reducing or preventing the age-dependent DNA mutations that cause cancer. Longo and his collaborators began studying SIR2 in 2000, soon after a well-known set of experiments by Leonard Guarente at the Massachusetts Institute of Technology. Guarente was the first to show t...

MUHC investigators search for the root of sexual pain in women

... sexual intercourse) and vaginismus (vaginal spasm preventing intercourse). These conditions, which were previously considered sexual dysfunctions, are now increasingly understood as pain disorders as a result of previous research by this team. "Approaching this problem in the context of pain is a more accurate...

Bats use touch receptors on wings to fly, catch prey, study finds

...em when their wing position or curve is incorrect, preventing the creatures from stalling in midair. "It's like a sail or a plane. When you change the curve of a wing a little bit, you get improved lift. But if you curve it too much, the bat ?or plane ?may suddenly lose lift, hitting a stall point and falling ...

Research: Snails were overlooked contributors to marsh destruction

...thy marsh, then enclosed the plots with wire mesh, preventing snails from reaching the grass. They put enclosures in the path of expanding die offs, as well as in remnants of healthy marsh. After 14 months, the patches were "robust and green" compared with denuded areas where snails moved through. ...

In studies at the University of California's Bodega Marine Reserve, a 362-acre preserve located about 60 miles north of the UC Berkeley campus, Simms and her colleagues set out to test some of ...

Performing monkeys in Asia carry viruses that could jump species to humans

Such precautions can help reduce the risk of bites and scratches from the monkeys. This study included researchers at Bogor Agricultural University in Bogor, Indonesia, a...

'Computer-chemistry' yields new insight into a puzzle of cell division

...us cancers. Anti-cancer drugs that jam the enzyme, preventing its docking with the kinase, could halt cell over proliferation to treat such cancers. However, developing such drugs has been hampered by lack of detailed understanding of how the Cdc25s fit with their associated kinases. "To me this is the culmin...

New maps reveal true extent of human footprint on Earth

To better understand that crucial trade-off, Ramankutty and other SAGE researchers are tracking the changing patterns of agricultural land use around the w...

Scientists directly view immune cells interacting to avert autoimmunity

...ype -- the antigen-presenting dendritic cell -- in preventing autoimmune attacks of healthy tissue has been a focus of intense research over the last 15 years. The new study supports one contending hypothesis: It is not the interaction between the two types of T cells, but rather the interaction of each with th...
