Tuberculosis: The bacillus takes refuge in adipose cells

...ogist from Hôpital Européen Georges Pompidou. They raise questions of considerable importance in the fight against tuberculosis. Tuberculosis kills almost two million people worldwide every year and is considered by the World Health Organisation to represent a global health emergency. However, the bacill...

Renewed dolphin slaughter prompts new campaign

New biochip helps study living cells, may speed drug development

...ll to determine the most efficient. Then you could raise the one that needed the least fertilizer, rather than putting a lot of different genes into hundreds of plants and waiting for them to grow, as is currently done." In addition to the potential savings in time and money, Porterfield said the chip h...

Age-related changes in DNA repair illuminate the connection between age and genetic damage

...at make use of a matching template. These findings raise the question of whether the rapid but risky methods of DNA repair used by cells of young individuals contribute to the accumulation of genetic damage, and perhaps to the aging process itself. Older cells may use the safer repair methods, but they sti...

A giant among minnows: Giant danio can keep growing

... danios, members of the minnow family, are easy to raise and are popular inhabitants of home aquariums. The...a staple of genetic research because it is easy to raise and maintain. But the fish is too tiny for physiological research. So the researchers were intereste...

UCSD study reveals how plants respond to elevated carbon dioxide

...edition of PNAS. "As human activity continues to raise atmospheric carbon dioxide levels, a better understanding of how plants respond to carbon dioxide is becoming imperative," said Julian Schroeder, a professor of biology at UCSD who directed the project. "Our results provide new insights into how an i...

Worm links cancer risk to ageing

...ours when the proteins are defective ?the findings raise the question of whether genetic variations in these proteins in humans places some individuals at risk of cancer. "Conversely, the checkpoint proteins may set a genetic course for a shorter life but one that is free from cancer." Dr Dale Bredesen, ...

The launch of AEY 2006 aims to raise people's awareness of the region's rich biodiversity, and strengthen regional cooperation and implementation of actions on environmental conservation. It supports ASEAN's commitment to achieve the goals of sustainable development envisaged in ASEAN V...

New study reveals structure of E. coli multidrug transporter protein

... expel." Multidrug resistant bacterial infections raise the cost of medical treatment and are far more expensive than treating normal infections. Treating drug-resistant tuberculosis, for example, requires so-called second-line drugs if standard treatment fails. According to the Centers for Disease Contro...

Pure novelty spurs the brain

...hey concluded. Finally, they said their findings raise the possibility that selective brain injury to the hippocampus could eliminate the positive effects of novelty in such patients and constitute one source of reduction in recognition memory in the patients. ...

One therapeutic dose of radiation causes 30 percent spongy bone loss in mice

...lose bone after radiation exposure, so the results raise a red flag. Bateman noted that a recent clinical study of 6,000 cancer patients reported in the Journal of the American Medical Association found that post-menopausal women who received pelvic radiation for cervical and colorectal cancer increased th...

HIV-1's high virulence might be an accident of evolution

...the host," the researchers said. The results also raise the possibility that treatments that could carefully limit the immune system in infected humans--mimicking the tight balance maintained in the other primates--might offer a new approach to HIV therapy, Kirchhoff said. "A strong immune response can b...

Brain enzyme treatment relieves memory lapse in Alzheimer's mice

..."By injecting what is essentially a Uch-L1 drug to raise its levels in the brain, we were able to restore a great deal of brain activity in a transgenic mouse model of Alzheimer's disease," said Michael Shelanski of Columbia University. "While amyloid beta is certainly a key player in Alzheimer's disease...

Study shows hope for ridding lakes of clawed invader

...compete with native invertebrates and, in general, raise havoc with the near-shore community of a lake," says Stephen Carpenter, a UW-Madison professor of limnology and zoology involved in the study on Sparkling Lake in Vilas County, Wis. Supported by the National Science Foundation (NSF), the long-term...

'Scent of a woman' tells male redback spiders to find a mate

...en think finding a nice partner to settle down and raise children with is tough, consider the plight of the male Australian redback spider. Instead of personality conflicts, spats over in-laws and financial worries, imagine that immediately after the first time you have sex, your partner -- who is 100 to 2...

Most human-chimp differences due to gene regulation ?not genes

This is a very efficient way to make big changes with very little effort, according to Gilad. By altering transcription...

For the first time: Longevity modulated without disrupting life-sustaining function

...oss many species, including humans, these findings raise the prospect that one day it might be possible to medically tweak this pathway to slow aging and improve the quality of life without harmful consequences to the body. In humans and other mammals this signaling cascade is known as the insulin/IGF-1 ...

Genetic mutation linked to West Nile virus infection

... mechanism is at play in humans. This study might raise a red flag for the use of CCR5 inhibitors in HIV-infected patients -- at least in areas endemic for WNV -- as such inhibitors might increase the recipients' vulnerability to severe WNV infection. ...
