New research indicates a 'troubled' greenhouse is brewing

...ness are less likely to be in our future than heat stroke and malaria," Retallack asserts. "Mint julep, anyone?" Buried soils have long been known as sources of evidence of past rainfall, but Retallack says they also can be used to determine the seasonality of rainfall as well as the amount of rainfall bec...

UF Researchers Map Bacterial Proteins That Cause Tooth Loss

... periodontal disease also are at increased risk of stroke and heart attack, and the disease makes it difficult to control blood sugar levels in people with diabetes. If that’s not bad enough, pregnant women with periodontal disease are seven times more likely to deliver low-birth-weight, preterm babies. Pro...

Antibiotic might fight HIV-induced neurological problems

...myotrophic lateral sclerosis, Alzheimer's disease, stroke and more. The drug is being tested in early clinical trials for some non-HIV-related conditions. "Last year we discovered that SIV triggers some of the same biological pathways of cell death and inflammation as these other diseases," says Sheila Bar...

Multi-purpose protein regulates new protein synthesis and immune cell development

...ctivated in many diseases from viral infections to stroke to Alzheimer's disease," says Kezhong Zhang, Ph.D., a senior research associate in biological chemistry and first author of the paper. "All these things disrupt protein folding and put stress on the cell. By doing so, they activate the UPR." Several...

Brain-injury rehabilitation depends on acetylcholine circuitry

...bility of the brain to recover from such injury as stroke or trauma depends on a particular circuitry of neurons that "talk" to one another using the brain chemical acetylcholine, researchers led by James Conner and Mark Tuszynski in the Neural repair Group at UCSD have discovered. Their finding in rats cou...

Newer imaging techniques may lead to over-treatment

... study found a 10 times higher risk of hemorrhagic stroke in patients receiving oral anticoagulant therapy when compared to the general population," Dr. Prologo said. It is imperative that "clinicians consider the risk-benefit ratio of therapy in patients with previously undetectable small clots in the peri...

Researchers discover stem cell 'guide' that may be key for targeting neural stem cell treatments

... diseases like Alzheimer's and Parkinson's, or for stroke and other brain injuries." While all neurons are originally born and differentiated from their stem cell progenitors during development, the adult brain maintains at least some regions where neural stem cells create new neurons to replace old and dy...

Researchers grow stem cells from human skin

...inal cord injuries, diabetes, Alzheimer's disease, stroke and burns. Most scientists believe that stem cells from human embryos are the most versatile type of stem cell because they have the potential to form any cell or tissue in the body. But they are also exploring the potential of stem cells from adult...

OHSU researchers discover potential mechanism to repair brain damage linked to Multiple Sclerosis

...a wide range of patients from premature infants to stroke victims to those suffering from debilitating neurological diseases such as MS where repair of damaged myelin does not occur." Sherman shares this hope. "This discovery has revealed a target for therapies and opens the door to the exciting possibilit...

Molecular Partners Required For Appropriate Neuronal Gene Repression

Sherman shares this hope. "This discovery has revealed a target for therapies and opens the door to the exciting possibilit...

Biotechnology's newest chemical tool

...ludes sensors for tension, force, joint angle, end stroke and contact in the final prototype. This prototype uses Longitudinal IntraFascicular Electrodes (LIFEs) to connect the hand to the nervous system. Within the CYBERHAND project, in addition to traditional wire LIFEs, a new type of electrode has been ...

Anti-cancer drugs may hold promise for premature aging disorder

...sues, typically causing death from heart attack or stroke at about the age of 12. "Our findings show that FTIs, originally developed for cancer, are capable of reversing the dramatic nuclear structure abnormalities that are the hallmark of cells from children with progeria. This is a stunning surprise, rat...
