A natural chemical found in strawberries boosts memory in healthy mice

...by Alzheimer's disease and other forms of dementia continues to rise. "Since the development of a basic understanding of the biochemical pathways involved in memory formation, the holy grail of CNS research in the pharmaceutical industry is the identification of a safe, orally active drug that activates memo...

HIV exploits competition among T-cells

...utates fast enough to escape initial detection and continues to mutate over time. The third phase, AIDS, occurs when the virus has changed so much that the body's T cells are no longer effective at keeping it in check. Deem and Wang's computer model accurately describes all three phases of HIV infection by i...

New HIV statistics indicate increasing toll of AIDS on African American community

...hose living with and dying from AIDS. The disease continues to affect African-Americans more than any other racial/ethnic group in the United States. Today, African Americans comprise only 13% of the U.S. population but account for over half of all new HIV/AIDS diagnoses. Over 200,000 African-Americans have...

New engineered drug may offer prolonged arthritis relief

..., adding that as the average age of the population continues to rise, the incidence of osteoarthritis will increase. Osteoarthritis had been attributed primarily to the gradual wear and tear of joint surfaces. More recently, however, scientists have discovered that inflammation sparked by the immune system a...

Did 'ABCs' cause Uganda's fall in HIV rates?

...e much-publicized "ABC" approach to HIV prevention continues to be mired in controversy, partly because of its focus on abstinence-only sex education programs over condom promotion, a focus that pits political and religious conservatives against their liberal counterparts. Nevertheless, the ABC approach is so...

'Best of both worlds' -- Targeting a single gene could inhibit bone decay and stimulate bone growth

...ill only become a bigger problem as the population continues to age. "The main challenge is how to prevent bone decay while also encouraging bone growth," said Choi. The basic principles behind bone metabolism are largely understood, hence a handful of drugs treating osteoporosis are available. Most dr...

Siberian lakes burp 'time-bomb' greenhouse gas

...rost is like a time bomb waiting to go off - as it continues to thaw, tens of thousands of teragrams of methane can be released to the atmosphere enhancing climate warming," Walter said. "This newly recognized source of methane is so far not included in climate models." Using remote sensing, aerial surveys an...

Transmission of antibiotic-resistant bacteria linked to previous intensive care unit room occupants

... as the prevalence of treatment-resistant bacteria continues to rise. "Additional data are needed to determine whether more intensive cleaning practices can reduce the risk further and, if so, whether this is worthwhile in a resource-limited system," the authors conclude....

Malaria may fuel spread of HIV in sub-Saharan Africa

...berculosis," Abu-Raddad said. "As long as HIV/AIDS continues to spread, it will aggravate the difficulties we face with these other diseases and may contribute to the emergence of more lethal or drug-resistant strains of these infections," Kublin added. ...

Environmental toxins may cause body's defenses to worsen lung disease

...ecognizes the tissue, Borchers explains, it simply continues its survey for problems. But if the cell receives a signal that the tissue is infected, it will automatically destroy it to protect the body from disease. "The immune system thinks it's eradicating disease from the body when it destroys cells that h...

In a project that continues to build on this line of work, Hakansson is collaborating with U-M Health System cancer surgeon Diane Simeone to investigate sugars attached to proteins in the membranes of pancreatic cancer cells. "The work is in very early stages, but we hope th...

Fungal factories may save hemlock forests

...ng hemlock for the tanning industry is over, there continues to be use of the tree for fiber and construction, and commercial forest owners have something to lose with the demise of the hemlock.

How fish conquered the ocean

...ommon knowledge that water is essential for life," continues Dr. Finn, "so it seems a surprising paradox that fishes that live in water should have a problem acquiring it. Yet it was this paradox that provided the trail of clues for us to follow". "The physiological problems of reverting from a fresh water ...

Satellites shed light on global warming

As climate change continues to make headlines across the world, participants at the 2007 Envisat Symposium this week are hearing how Earth observation satellites allow scientists to better understand the parameters involved in global warming and how this is impacting the planet...

Biologists produce global map of plant biodiversity

...ng among ecologists about this striking difference continues to be very limited. "Given that we are far off from knowing the individual distributions of the world's 300,000 odd plant species," says Jetz. "Holger Kreft and I investigated how well the richness of plants can be predicted from environmental con...

Lead with a poisonous electron shield
