Study supports activity of GEMZAR in the treatment of early-stage breast cancer
...ponent of the study. Patients received a first sequence
of epirubicin and cyclophosphamide (90/600 mg/m2) for three cycles followed by a second sequence

Mercury's link to heart disease begins in blood vessel walls
... The activation of the enzyme involves a complex sequence
of events in the cell membranes that in turn releases phosphatidic acid, which can damage cells in the vessel lining called endothelial cells and is believed to contribute to vascular disorders. To further test the enzyme's role in blood vessel ...

New study in Sleep finds a high level of negativity towards judicial sleepiness
...ny and legal arguments. The Daily Telegraph, in a sequence
of investigative articles, reported a lengthy list of Judge Dodds sleep episodes between 2002-2004 that appeared to affect court proceedings. In late 2004, Judge Dodd obtained a medical consultation regarding his sleepiness, was diagnosed with obstr...
Green tea compound suppresses factors causing cartilage, bone destruction in arthritis
... When untreated cells were stimulated with IL-1, a sequence
of molecular events occurred that resulted in production of the bone-destructive molecules. But the scientists found that pre-incubation with EGCG was capable of blocking the production of these molecules in a dose-dependent manner. Furthermore, EGCG...
Green tea compound may be a therapy for people with rheumatoid arthritis
... When untreated cells were stimulated with IL-1, a sequence
of molecular events occurred that resulted in production of the bone-destructive molecules. But the scientists found that pre-incubation with EGCG was capable of inhibiting the production of these molecules. EGCG also inhibited the production of pros...
Scientists find missing link to understand how plants make vitamin C

Wired for sound: How the brain senses visual illusions
...de is that the illusion depends on a rapidly timed sequence
of interactions between the auditory and visual cortical areas." "This is part of a set of new findings by scientists in the field that show how integration of multiple sensations can happen much more rapidly than we thought before," said Mishra. ...

Research agreement to advance new imaging technology
...nd PET scanners reconstruct images by converting a sequence
of two-dimensional images which are captured by a receptor as it rotates around the patient into a three dimensional image. While these technologies have provided doctors an invaluable view into the human body, the images often contain flaws. Ra...
