Statin treatment improves spatial memory in mouse models of Alzheimer's

... genes, were acclimated for one week, with as much food and water as they wished, then divided into four groups. Half the “Alzheimer’s mice?and half the normal mice received 10 mg/kg Simvastatin for seven days, while half of each group only received saline. Each day the mice had two swimming trials in the...

Early exposure to indoor fungus molecules may protect infants against future allergies

...y visible mold and water damage. Environmental and food allergy development was monitored through annual skin prick tests. Scientists say early-life exposure to common microbial components—like bacterial endotoxins and fungal glucans—can stimulate the body’s immune system to produce infection- and alle...

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

...protective effects from antioxidant-rich foods and food extracts is a promising area of research, says Bolling, who is the Gayle Halperin Kahn Professor of Integrative Medicine, a professor of cardiac surgery, co-director of U-M Integrative Medicine and member of the U-M Cardiovascular Center.

Hearts of male and female rainbow trout are different

... the Pacific Northwest and beloved as a sport- and food fish, requires dynamic and sustained cardiac function to maintain its health and swimming activity. Previous studies of trout cardiac performance and energy metabolism have been conducted under hypoxic (oxygen shortage) conditions, but gender was ...

Global survey of lizards reveals greater abundance of animals on islands than on mainland ecosystems

...llion people depend on island ecosystems for their food and livelihoods.? The study suggests that islands are particularly sensitive to the loss and gain of species. Species introductions have had dramatic consequences for islands. Introduced mongooses have devastated island populations of lizards and ...

Keeping the immune system from starting a 'food fight'

...sposition to obesity due to other factors. When food enters the system, STAMP2 normally keeps the immunity response "button" from getting pushed, Hotamisligil said. "We suggest that, over time, the accumulation of small cellular stresses due to daily changes and fluctuations in nutrients in STAMP2-d...

New knowledge improves rice quality

The quality rice network ?which was formed electronically in 2006 ?met for the first time last month during a three-day workshop entitled "Clearing Old Hurdles with New Science: Improving Rice Grain Quality" at IRRI. The even...

Healthy coral reefs hit hard by warmer temperatures

...t live in the polyps. The algae supply much of the food coral need to survive. When disease or stressful environmental conditions strike a coral colony, the polyps expel their algae. This algae loss makes the coral appear pale. "We're left with a big question. Can corals and other marine species suc...

New bacteria test could improve quality of fruit and vegetable juice

Increasingly, consumer products, especially food and beverage products, are being scrutinized for b...quality. At the University of Missouri-Columbia, a food science expert has developed a rapid, reliable and efficient technique to ensure fruit and vegetable...

DNA repair proteins monitored at double-strand break

...anded DNA caused by radiation, natural oxidants in food or the body and other toxins that can cause disease and aging. "Prior to this work, there was no practical and efficient way to find and study the DNA repair proteins that organize themselves on and around a double-strand break in human cells," sa...

Survival of the rarest: Fruit flies shed light on the evolution of behavior

...eding and they are also more likely to explore new food patches than sitters. The researchers explored the evolutionary mechanism that favours the persistence of both of these types in nature. Doctoral student Mark Fitzpatrick raised colonies of flies with different ratios of rovers to sitters and diff...

Parasites' impact goes beyond host to affect ecosystem

Over the three-and-a-half-week field experiment, ephemeral algae increased 186 percent in the no-snails control cage and 59 percent in the cage of infected snails; it decreased by six percent in the un...

100 percent of pregnant women have at least one kind of pesticide in their placenta

Study warns deep-sea mining may pose serious threat to fragile marine ecosystems

...these nutrients could drift widely, disrupting the food chain and potentially damaging ecosystems that lie within other countries?economic zones or in international waters. This poses additional problems, because while a state has the right to exploit its own resources, international environmental law dec...

A new portable biosensor detects traces of contaminants in food more quickly and cheaply

Fish extinctions alter critical nutrients in water, study shows

...other species rely on. Algae, at the base of the food chain, for example, rely on fish to cycle back into the water such nutrients as nitrogen and phosphorus, which are otherwise locked up in animal or plant cells. Fish excrete dissolved nutrients back into the water, making them available to algae, whi...
