Drug resistant avian influenza viruses more common in Southeast Asia than North America

...nsmission was reported in Vietnam. This has so far prevented H5N1 from becoming a major threat to humans. "However, if H5N1 variants acquire the capacity for sustained human-to-human transmission, the world will face the threat of a serious pandemic," said Robert G. Webster, Ph.D., a member of the Infectious ...

Updated data on novel HPV vaccine confirms efficacy in large population

...otocol (e.g. by missing visits, etc.), the vaccine prevented 99 percent of HPV 16 or 18-related high-grade cervical pre-cancers (1 of 9,342 pts versus 81 of 9,400 in the placebo group) with an average follow up of 25 months. The vaccine was generally well tolerated, and the most common adverse event report...

Researcher at UGA College of Veterinary Medicine identifies new way of combating viral diseases

...for viruses to reproduce in a cell.Disrupting Rab9 prevented the replication of four different viruses ?Marburg, Ebola, HIV-1, and measles viruses. "We believe that interfering with the Rab9 pathway interferes with the ability of the viruses to exit the cell, thereby dramatically decreasing the ability of the...

Corn grain mould used as pesticide

...lds with mould, it is claimed. "It can scarcely be prevented that maize or nuts will be infected to a certain extent with brown mould," Sebastian Kiewnick emphasises. "We can only influence which strain of aspergillus grows on it: a dangerous producer of toxins ?or the non-toxic variant." ...

Experimental shingles vaccine proves effective in nationwide study

...rimental vaccine against shingles (zoster vaccine) prevented about half of cases of shingles--a painful nerve and skin infection--and dramatically reduced its severity and complications in vaccinated persons who got the disease. The findings appear in the June 2 issue of The New England Journal of Medicine. T...

Hurricane aftermath: Infectious disease threats from common, not exotic, diseases

...tic diseases. These common infections can often be prevented using simple hygiene measures and a little common sense. "Deadly diseases, such as typhoid or cholera, are unlikely to break out after hurricanes and floods in areas where these diseases do not already naturally occur," says Ruth Berkelman, MD, Chai...

Opiate cocktail may spare cells from morphine's dark side

...combination of morphine with the methadone mixture prevented the activation of cellular signaling pathways associated with morphine tolerance and dependence. They also showed, perhaps most importantly, that whereas rats receiving only morphine develop tolerance to the drug, those rats receiving the morphine/me...

Newly Discovered Role for Heart Response Enzyme May Yield Better Heart Failure Therapy

...of tropomyosin by PI(3)K in cells, the researchers prevented heart receptors from leaving the cell surface, thereby blocking the initial step that occurs during heart failure. Also, the researchers reported, when they eliminated tropomyosin activity altogether, they also maintained heart receptors. "These stu...

Hormones and growth: The control of body size and developmental growth rate in fruit flies

... contrast, inhibiting Ras in the prothoracic gland prevented ecdysone release and delayed development, creating flies that are much larger than normal. On the basis of their findings, the investigators conclude that Ras activity in the prothoracic gland regulates body size and developmental rate by regulating ...

Hopkins scientists uncover 'tags' that force proteins to cell surface

The application of these surface tags to force protein transportation to the cell surface is the subject of a Patent Cooperation Treaty (PCT) patent application submitted by The Johns Hopk...

Unexpected lock and key mechanism found for the assembly of tumor blood vessels

...t inhibit either the integrin or the VCAM molecule prevented intact blood vessels from forming. "When the integrin meets with VCAM, both cell types receive survival signals at this active stage of blood vessel development, which occurs mainly in tumors in adults," said Varner. "This was a chance discovery, wh...

Study shows humans have ability to track odors, much like bloodhounds

"We think that most people failed to replicate his results for that reason, that is, the extent to which they enabled natural behavior, specifically sniffing," Sobel said. "In some studies subjects asked to localize an odor w...
