Chocolate, wine, spicy foods may be OK for heartburn, Stanford study finds

...days that's usually a proton pump inhibitor, which reduces the amount of acid secreted in the stomach. Gerson said that for the most part, medication alone is adequate to treat the symptoms of heartburn. "The main reason they probably have heartburn is that their sphincter muscle is relaxing too much and ta...

Study finds how organs monitor themselves during early development

...rm cells. "But if there is very little Spitz, that reduces the number of intermingled cells and thus the number of germ cells will rise," Dr. Gilboa says. This feedback loop acts as a sensor that ensures there are sufficient primordial germ cells in the ovary at the end of larval development. The level of...

Survival of the selfless - scientists find cheats don't always prosper

...n for the individual, it is a wasteful method that reduces resources available for the group as a whole. The researchers were surprised to find that in a well-mixed population the cooperators were not excluded by the cheats. Further experiments and mathematical modelling established that this is because ch...

Parkinson's disease mechanism discovered

...-synuclein accumulation. The death of such neurons reduces brain dopamine levels, causing the tremors and other symptoms of Parkinson's disease. Dopamine is one of many types of neurotransmitter -- chemical signals that one neuron launches at its neighbor to trigger a nerve impulse. "Of all the neurotransmi...

Sandia work launched on space shuttle shows live cells influence growth of nanostructures

...nization and the form of the silica nanostructure, reduces stress, and ultimately improves the living conditions of the ensconced cellular tenants. The work was initially funded by Sandia's Laboratory Directed Research and Development (LDRD) office, and then by DOE's Basic Energy Sciences group for its fun...

Long-term changes in experience cause neurons to sprout new long-lasting connections

... to adapt to loss of the whiskers ?a strategy that reduces dependence on lost whiskers and enhances input from intact whiskers. "We knew from previous work that a subpopulation of dendritic spines appears and disappears over time, but we didn't know the biological meaning of this process," said Svoboda. "In...

NASA technology helping injured US troops

... legs cannot support their body weight." Using SAM reduces the pressure on the legs, and allows them a chance for increased exercise until they are strong enough to stand on their own. "SAM helps us to help them strengthen their whole lower body. The technology has a lot of promise," said Castleberry. "It'...

Researchers develop flood-tolerant California rice

...more than four days. Water covering the rice plant reduces the plant's oxygen and carbon dioxide supplies, affecting photosynthesis and respiration. Submerged, the plants lack the gases needed to produce sugar for cellular energy, resulting in death if submergence persists beyond four days. Bailey-Serres ...

Magnetism and mimicry of nature hold hope for better medicine, environmental safety

...ire much larger amounts of fluid for testing. This reduces the expense of testing because you don't need large amounts of very expensive chemicals to do the analyses." Perhaps the most critically important thing the method will help save is time, especially in medical diagnoses. "You might be able to get ...

Bird flu study highlights need to vaccinate flocks effectively

...Centre for Infectious Diseases, said: "Vaccination reduces the chance of birds becoming infected and reduces the amount of virus they shed and the time over which they shed it. If vaccination is to be used it ...

Tropical forest CO2 emissions tied to nutrient increases

...le slash-and-burn agriculture in the tropics often reduces soil phosphorus in the long run, the practice can initially make more phosphorus available to tropical soil microbes, increasing their metabolism and the amounts of CO2 they emit, he said. Phosphorus and many other nutrients are regularly transporte...

Natural pine bark extract relieves muscle cramp and pain in athletes and diabetics

...cipants demonstrated that Pycnogenol significantly reduces muscular pain and cramps in athletes and healthy, normal individuals. "With the millions of athletes worldwide, this truly is a profound breakthrough and extremely significant for all individuals interested in muscle cramp and pain relief with a na...

Dominant meerkats render rivals infertile

... hormones and a collapse in fertility. This tactic reduces conception rates and increases abortion rates among the evicted subordinates, who are only allowed to return to the group after the dominant female has given birth. The dominant female benefits in two ways from reducing the fertility of her subor...

Meth promotes spread of virus in HIV-infected users

... in the September issue of the journal. "Meth reduces inhibitions, thus increasing the likelihood of risky sexual behavior and the potential to introduce the virus into the body, and at the same time allows more virus to get into the cell," said Nair, professor of medicine and a specialist in immunology...

Drug dials down the energy within cells, UM researchers find

...In previous work, Glick's group showed that Bz-423 reduces effects of arthritis and the autoimmune disease lupus in mice and may be useful in treating psoriasis. Unlike conventional drugs for these conditions, which can't discriminate between healthy and disease-causing cells, Bz-423 is highly selective, hom...

Pollutant haze heats the Arctic

...louds more effective at reflecting sunlight, which reduces surface temperatures. So the newly discovered effect is a surprise. "What we found is an opposing effect where particulate pollution changes clouds so they warm the surface," Garrett says. "This effect is most pronounced in Arctic winter when it is...

Research offers new hope for preterm babies

...eterm babies suffer from low blood pressure, which reduces the oxygen supply to their brain," said neonataologist and MIMR PhD student, Dr Flora Wong. "This makes them much more vulnerable to a range of neurological problems such as cerebral palsy, blindness, deafness, low IQ levels and hyperactivity." "In ...

K-Staters design and build a low-cost remote sensing tool for environmental studies

...compromise the data collection systems and greatly reduces vibration." According to Schinstock, the remote sensing tool will meet a need shared by thousands of environmental scientists worldwide. For just a few thousand dollars, researchers will have a way to collect data for small ecosystem sites at low al...

EGCG also reduces the amount of platelet aggregation, regulates lipids, and promotes proliferation and migration of smooth muscle cells, which are all factors in reducing cardiovascular disease, he said. Sumpio said other reports show that EGCG prevents growth of ce...
