...ting specific groups, using antiviral medications, restricting travel or implementing other public health measures," said Irene Eckstrand, Ph.D., MIDAS program officer at NIGMS. "Computer models let us envisage the impact of these decisions in a variety of scenarios." The ultimate goal of the project, added Eck...New tumor-suppressor gene discovered
...ants may regulate cell number and tissue growth by restricting the proliferation of cells and promoting their timely death," Lai says. This is the first time that any gene in the large superfamily to which the mats gene belongs has been shown to play a critical role in growth inhibition. The scientists began...World's largest rainforest drying experiment completes first phase
...ir leaves become clogged with water vapor bubbles, restricting their growth for years to come? These are just some of the questions that will be explored during the final two years of this experiment. Collaborating organizations in this effort include IPAM (Instituto de Pesquisa Ambiental da Amazonia), EMBRAPA ...Muscle-targeted gene therapy reverses rare muscular dystrophy in mice
...ght Koeberl, M.D., senior author of the study. "By restricting the expression of introduced genes to muscle, the immune response can be prevented or attenuated." The muscle-targeted gene therapy might therefore apply to other forms of muscular dystrophy, they added. Muscular dystrophies include many genetic dise...Newly discovered genetic disease sheds light on body's water balance
... adults retain too much water we can treat them by restricting fluid intake," he said. "We can't do that with infants -- almost all of their nutrition comes in liquid form." The physicians were reluctant to use other medications that generate increased water loss in the kidneys, as these can have side effects or...Study: Plants use dual defense system to fight pathogens
...hese kinds of responses are extremely important in restricting the growth of many pathogens." The other pathway uses disease-resistant proteins, or R-proteins, which can detect certain molecules, called effectors, that are secreted by pathogens. This pathway produces a stronger immune response than the PAMP pat...Rare chalk grassland takes 50 years to recover from military use

Although the longevity phenomenon was well documented in laboratory animals, researchers remained unsure about how it happened. Now, the experiments by Kaeber......Medicine, "everyone lost someweight as a result of restricting calories, but people who had highlevels of insulin secretion and ate a diet with a low glycemic load lostthe most weight."
