The disorder Maedi-Visna that is detected in sheep affects on mammary gland. As it says in the source language, Icelander, it affects lungs and nervous system. The disorder is produced by the lentivirus Maedi-Visna, which belongs to the family of Aids. This virus infects sheep, and until now, there is no evidence of the transmission to humans. This virus, which is known since many years, causes a very slow evolution of the disorder. Therefore, shepherds often do not detect the infection, because shee

Deguelin may inhibit growth of Akt, an essential molecule in the promotion of precancer

The use of deguelin, a natural plant extract most commonly used as an insecticide in Africa and South American, inhibits the growth of precancerous and cancerous lung cells, with no toxic effects on normal cells, according to a study presented today at the first annual Frontiers in Cancer Prevention Research meeting convened by the American Association for Cancer Research. The role of deguelin as a

Researchers have found that immediately treating people who have early stage glaucoma can delay progression of the disease. This finding supports the medical community’s emerging consensus that treatment to lower pressure inside the eye can slow glaucoma damage and subsequent vision loss. These results are reported in the October 2002 issue of Archives of Ophthalmology.

Scientists found that immediate treatment of newly-discovered primary open-angle glaucoma, the most common form of glaucoma

In a discovery with implications for treatment of anxiety disorders, UCLA Neuropsychiatric Institute investigators have identified a distinct molecular process in the brain involved in overcoming fear. The findings will be published in the Oct. 15 edition of the Journal of Neuroscience .

The study of how mice acquire, express and extinguish conditional fear shows for the first time that L-type voltage-gated calcium channels (LVGCCs) — one of hundreds of

Findings are cover story of Oct. 15 issue of Cancer Research

Researchers at Cedars-Sinai Medical Center’s Maxine Dunitz Neurosurgical Institute have successfully tested a new treatment for brain cancer by utilizing neural stem cells to track and destroy cancer cells within the brain. Scientists hope the encouraging results may eventually lead to an effective treatment for glioma, the most aggressive form of primary brain tumor in humans. The study, conducted in mice with experime

A theory that suggests the aging process might be safely slowed by targeting genes that are quiet early but threaten damage later in life has gotten a boost from new findings from the University of Illinois at Urbana-Champaign.

The researchers don’t promote such tinkering in their paper, which appears online this week in advance of publication by the Proceedings of the National Academy of Sciences. Rather they detail their tests, based on models of mathematical prediction, of the two l
