Experts predict Tamiflu could halve the pandemic influenza death toll versus no intervention

...ut their effectiveness would be dependent upon how well the vaccine was matched to the virus.1 “The World Health Organisation provides a strong recommendation for the use of Tamiflu for the prevention of avian flu in people who have been in contact with someone who is known, or suspected of being infec...

Experimental gene therapy 'abolishes' arthritis pain and lessens joint damage

...develop the disease, the authors said. If all goes well with a follow-up study currently underway, researchers will apply to the U.S. Food and Drug Administration for permission to begin human trials next year. Nearly everyone aged 65 or older suffers from the pain, swelling and permanent joint damage of...

Ants show us how to make super-highways

...izes of hole into the army ants’ trails to see how well different sizes of ant matched different sizes of pot hole. Indeed, they fit beautifully", explained Franks. Overall, this behaviour results in an increase in the average speed of prey-laden traffic. Moreover, calculations suggest that under a ra...

Researchers use MRI to predict recovery after spinal cord injury

...to determine the degree of neurological damage, as well as a possible prognosis. MRI findings may include cord hemorrhage, swelling, soft tissue and ligament injury, blood clots or herniated discs. Dr. Fehlings’ study included 100 patients with traumatic cervical SCI. The group consisted of 79 men and ...

HIV and malaria combine to adversely affect pregnant women and their infants

...ected samples from women in the first pregnancy as well as from women in their subsequent ones living in the Kenyan region where malaria is common. The researchers demonstrated that protection to PAM is mediated by a special type of antibody that allows women to preferentially clear the parasites in their...

First confirmed common genetic risk factors for breast cancer

...00 women -- including those with breast cancer as well as those without the disease – has uncovered five ...ific institutions in other countries of Europe, as well as the U.S., and Australia. ...

Cytomegalovirus exacerbates atherosclerosis through an autoimmune mechanism

...lso recognises a genetic influence. However, it is well known that acute cardiovascular events may happen without the presence of the mentioned common risk factors. Recently inflammation and infectious agents have been shown to play an important role in the onset of acute cardiovascular events. The o...

Want to save polar bears? Follow the ice

...to form a picture of polar bear habitat history as well as where this habitat most likely remain in the future under global warming projections. When combined with meteorological data, the researchers hope to distinguish short-term, seasonal effects and large scale phenomena such as the Arctic and North A...

For many insects, winter survival is in the genes

...stress proteins during times of low temperature as well as during exposure to high levels of toxic chemicals, dehydration and even desiccation," Denlinger said. He and his colleagues first figured out how many genes were turned on only during the flesh fly's dormant state. The researchers extracted and...

Moths mimic sounds to survive

...lso recorded the sounds emitted from each moth, as well as the sounds made by the bats. All the bats quickly learned to avoid the noxious moths first offered to them, associating the warning sounds with bad taste. They then avoided a second sound-producing species even though it was not chemically pr...

HIVMA opposes The Gambia's unproven AIDS remedy

HIVMA joins its colleagues in the International AIDS Society and the Society for AIDS in Africa in expressing great concern regarding this practice....

Arctic ice retreating more quickly than computer models project

...IPCC- projected timeframe of any time from 2050 to well beyond 2100. The authors speculate that the computer models may fail to capture the full impact of increased carbon dioxide and other greenhouse gases in the atmosphere. Whereas the models indicate that about half of the ice loss from 1979 to 2006...

Puzzling plankton yield secrets to role in evolution/global photosynthesis

...mely small eukaryote to thrive in nature—which may well find applications in bioengineering," said Palenik. "It was particularly interesting to see the predicted use of selenium-containing enzymes as one of the tricks to maintain such tiny cells. There are many mechanisms that can account for species for...

Salk scientists hammer out a pathway that promotes muscle cell survival in mice

... different conditions, such as during exercise, as well as what part it plays in maintaining cell survival in other tissue types and in other species." Indeed, all mammals have SIK1, not just mice, and even worms and fruit flies use variations of the enzyme. And as Montminy adds, "Application of this ...

A cherry on top: Tart cherries may alter heart/diabetes factors

... tart cherries, which are used in pies and jams as well as juice. They are different from the sweet Bing cherries that are often eaten raw, and have higher concentrations of antioxidant anthocyanins than sweet cherries. By the end of the study, the rats that received the 1-percent cherry diet had tota...
