...ed by transplanted dura mater. It is the outermost membrane covering the brain and spinal cord, which is used by surgeons to repair the skull and spine and to reinforce tendons and ligaments. Richard Knight and his colleagues of the National CJD Surveillance Unit at Western General Hospital, Edinburgh, publ...

Progression Of ALS May Be Prevented By A High Caloric Diet

...etones promote mitochondrial energy production and membrane stabilization. Mitochondiral membrane dysfunction, loss of oxidative stress control, generation of excessive free radicals, neurofilament ...

Lactic acid a potent energy giver if used properly!

...ere lactate is produced, through the mitochondrial membrane into the interior of the mitochondria, where lactate is burned. "This experiment is the clincher, proving that lactate is the link between glycolytic metabolism, which breaks down carbohydrates, and oxidative metabolism, which uses oxygen to break ...

Bicycle-Powered Portable Water Filter System For Disaster Zones

... of a bicycle coupled with a mechanical pump and a membrane module to filter the water. Believed to be the world's first, NTU experts said it is an improvement on the hand-cranked model made for Indonesia's tsunami-stricken Aceh Province in January last year. As an aftermath of the Dec 26, 2004 disaster, ...

Promise for Soya Allergy Sufferers

...ction. Seeds were crushed, treated and placed on a membrane for screening. A second screening using stronger antibodies and protein gels was done to confirm the absence of P34 in the two domestic lines, Joseph said. After the two lines were isolated, seeds were sent to the Danforth Center for additional mo...

Heparin Based Nanoscale Materials Developed For Dialysis Treatment

...The researchers demonstrated the composite heparin membrane with nanopores could work as an artificial kidney, or dialyzer, by filtering the blood and maintaining its flow. The presence of this blood-compatible dialyzer could potentially eliminate the need for systemic administration of heparin to the patient...

Autoimmune Diseases – Newer Preventive Measure

...thyroid, yeast infection of the skin and/or mucous membrane and adrenal gland insufficiency, two will result in a condition called APS1 (Mutation in the Aire gene) and nearly about 16 autoimmune diseases in a lifetime. The same mutation causes a defect in iNKT cells, a type of regulatory cell that helps the...

Reports Characterize Fungal Eye Infections Among Soft Contact Lens Wearers

...s, or swelling and inflammation of the transparent membrane known as the cornea, has been associated with wearing soft contact lenses, but such infections usually have not been caused by fungi. At the authors' institution in south Florida, only three cases of fungal keratitis associated with contact lenses w...

Anti-Glycolytic Therapy Proved to be Effective Against Tumors

Prion Disease Agent Causes Heart Damage

...o acids at the COOH end of the protein-between the membrane of cells and the prion protein. By taking off this anchor, the researchers showed that the prion protein still folded but was no longer able to attach in normal amounts onto the surface of cells. In contrast to scrapie-infected wild mice, which typic...
