Brain-computer link lets paralyzed patients convert thoughts into actions

...als, effectively restoring brain-to-muscle control via a physical nervous system." "Our researchers initiated the clinical trial with the hope of being able to develop a non-obtrusive system that would one day provide more freedom to those with severe paralysis," said Timothy Surgenor, president and C...

Sleep deprivation doubles risks of obesity in both children and adults

...ay lead to obesity through an increase of appetite via hormonal changes caused by the sleep deprivation. Lack of sleep produces Ghrelin which, among other effects, stimulates appetite and creates less leptin which, among other effects, suppresses appetite. However he says more research is needed to under...

Gene screen for breast cancer better than pathologist's 'eye'

...ough a process called ductal lavage, a saline wash via a catheter threaded through openings in the nipple leading to the vast network of breast ducts. Cytopathologists correctly identified seven of 21 (33 percent) fluid samples containing cancer, and ruled out the disease in nearly all cases negative f...

UC Davis researchers reveal apples' protective ways

...ally triggers cell death and promotes inflammation via a mechanism called the "nuclear factor (NF) kappa B pathway." This pathway involves chemical signaling between cells. The apple extract was able to protect the cells from the normal lethal effects of TNF. "Our study showed that the flavonoids in ap...

MIT 'seeing machine' offers hope to blind

... which represented the inside of an MIT building - via a joystick that allowed them to move forward, backward and sideways. All of the participants reported that the machine "may have the potential to assist their mobility in unfamiliar environments," according to the Optometry article. Concluded Goldri...

Key stress protein linked to toxicities responsible for Parkinson's, Alzheimer's

... levels in neurodegenerative diseases, attacks PDI via a chemical S-nitroyslation reaction, altering PDI's structure and blocking its normal neuroprotective function, which ultimately leads to nerve cell injury and even death. These new results also show that this altered form of PDI is present in eleva...

Cell phone emissions excite the brain cortex

...y & Sons. The article is also available online via Wiley Interscience (www.interscience.wiley.com/journal/ana). More than 500 million people in the world use cell phones which emit electromagnetic fields (EMFs). Though many studies have looked at the effects of EMFs on the body, few have focused on ...

Stanford snake venom study shows that certain cells may eliminate poison

...oxin 6b," said Metz. The mast cells were activated via a particular receptor they had on the cell surface and released the appropriate proteins, which, Metz said, went on to "degrade and thus eliminate the venom, or at least make it less toxic." The wild-type mice were able to withstand 10 times the do...

Microscopic scaffolding offers a 'simple' solution to treating skin injuries

...d over a wound, the patient's skin cells (obtained via a biopsy*) are introduced and attach themselves to the scaffold, multiplying until they eventually grow over it. When placed over the wound, the scaffold dissolves harmlessly over 6 to 8 weeks, leaving the patient's skin cells behind. This new app...

Honey helps problem wounds

... immune system. If a germ enters their bloodstream via a wound, the result may be a fatal case of blood poisoning. For several years now Bonn paediatricians have been pioneering the use in Germany of medihoney in treating wounds. Medihoney bears the CE seal for medical products; its quality is regularly...

New pathways for autoimmune treatment identified

...KT cells also go through a development process but via a somewhat different path than that of other T cells. MCG researchers have learned medullary epithelial cells in the thymus are critical to proper i NKT cell development. A defective Aire gene disrupts this natural nurturing relationship by disrupti...

Brittle prions are more infectious

...roteins that transmit their unique characteristics via interactions in which an abnormally shaped prion protein influences a normal protein to assume an abnormal shape. In mammalian prion infections, these abnormal shapes trigger protein clumping that can kill brain cells. In yeast cells, the insoluble p...

Bi-directional cellular communication is integral to both cancer progression and embryological development. The significance of the research team...

Rice scientists make first nanoscale pH meter
