Avoid sudden death by quick cooling

...ser the chances are for the patient to survive. In laboratory studies, Becker has demonstrated that the actual act of restarting the heart can cause significant damage. Therefore, he proposes giving the heart a rest by cooling the organ along with the brain before restarting it, so that the heart's cells can d...

Helping stroke patients to recover balance

...ilkete and her colleagues at the Lyon neurological laboratory of INSERM the French medical research agency, gave wedge shaped spectacles with prismatic lenses to patients with postural problems. These made objects appear 10 degrees farther to the right or the left than they were. As expected, when the patient...

Avacado a day

...an. Researchers fed avocado and 22 other fruits to laboratory rats. The rats were then given D-galactosamine, a substance that causes liver damage by interfering with cell synthesis and results in cell death. The rats fed the avocado obtained the least amount of liver damage.// The Researchers discovered three...

Recouping blood flow after a stroke

... speech and movement in many cases. Now a study in laboratory rats reveals that the blood supply of the brain can respond to stroke damage. Researchers at the Harvard University School of Medicine in the US simulated a minor stroke in a group of rats, by constricting the blood vessels in their brains.// When ...

Helping the neurology of kidney failure

... the neurological problems in kidney failure using laboratory rats. They find that nitric oxide - a molecule which acts as a chemical signal - interacts with free radicals so creating a condition called oxidative stress, which damages brain cells. However, if rats with kidney failure are treated with an antioxi...

The new compounds seem to be very interesting for the treatment of these tumors. // Previous drugs derived from hydroxyurea were extremely active in blocking the same cell targets as hydroxyurea, but had serio...

Research of Ritalin

...expression of a gene involved in brain function in laboratory rats. The same gene is known to be affected in humans by other psychoactive drugs, such as amphetamines and cocaine.// The research was presented this week at the annual meeting of the US Society for Neuroscience."Children have been given Ritalin d...

Syphilis uncovered

... the bacterium which causes syphilis, alive in the laboratory long enough to work on a vaccine or better treatments. Dr George Weinstock, who led the gene mapping study, said: "The genome sequence represents an encyclopedia of information on this elusive bacterium."We can now figure out ways to disarm its defe...

A novel augmentation

...tually allow whole human organs to be grown in the laboratory for transplant. Such transplants would be engendered by cloning from a patient's own cells and would therefore have no problems of negation. Makoto Asashima, who led the team, said the technology could provide an option to donor transplants. His te...

Broccoli's role against cancer

Scientists at two Italian universities conducted laboratory tests that showed coffee molecules prevent adhesion of S. mutans on tooth enamel. “All coffee solutions have high antiadhesive properties due to naturally ocurring and roasting-induced molecules,” says the lead author, Gabriella Gazzani, of Pavia ...

The route to fertilization

... in the Pacific Ocean just a few yards from Epel's laboratory on California's Monterey Bay. Experiments reveal that normal sea urchin sperm contains an enzyme called nitric oxide synthase, which remains inactive until a few seconds before fertilisation. "As the sperm approaches the egg," notes Epel, "the enzy...

Effective And Economical Agent For Anthrax
