- Cheetah Medical Inc. Introduces New System to Measure Accurately, and Non-invasively Patients' Cardiac Output and Other Hemodynamic Parameters

Cheetah Medical Inc. announces the U.S. Food and Drug Administration (FDA) approved for marketing the Reliant, a highly accurate, portable cardiac output monitor which provides a noninvasive window to cardiac and hemodynamic function. The Reliant monitor is powered by Cheetah's unique, patented BIOREACTANCE(R) Technology, which has been used effectively in over 1,000 patients in various clinical settings including hemodynamic monitoring, heart failure, perioperative care, hemodialysis and stress testing.

About the Reliant Technology

Researchers from the University of Granada have for the first time analyzed the antioxidant properties of olive oil, a product rich in polyphenols. The Environmental, Biochemical and Nutritional Analytical-Control Research Group had already carried out the polyphenolic characterization of food products, such as honey and beer.

In the 1960s, Ancer Keys, a US expert on nutrition, studied the health benefits of the Mediterranean diet for the first time. Since then many studies on the benefits of olive oil have been conducted.

Loneliness is commonly regarded as a social phenomenon in which individual personality differences contribute to its severity. Some people enjoy solitude, for example, because they never feel lonely, while people with high degrees of loneliness have shorter life expectancies than people who never feel lonely.

There may be more to it than that. Recent research shows that the gene expression in the immune cells of people with chronically high levels of loneliness is different than people who do not feel lonely. Even more telling, some genes were underexpressed in the same subjects, including those in antibody production.

A 53-page study designed to provide a comparison between the KC-767 Advanced Tanker (AT), based on the 767, and its major competitor in the U.S. Air Force's KC-135 Tanker Replacement Program states that a commercial 767 airplane is substantially more fuel efficient than the larger Airbus 330 - the 767 fleet burned 24 percent less fuel than the A-330s and would save approximately $14.6 billion in fuel costs.

That number is significant since the Air Force spent approximately $6.6 billion on aviation fuel costs in 2006.

The study used published data to calculate the fuel consumption of flying a fleet of 179 767-200ER and Airbus 330-200 airplanes over a 40-year service life.

In studies involving more than 35,000 people and a survey across the entire human genome, an international team supported in part by the National Institutes of Health (NIH) has found evidence that common genetic variants recently linked to osteoarthritis may also play a minor role in human height. The findings were released in Nature Genetics.

The variants most strongly associated with height in the new genome-wide association study lie in a region of the human genome thought to influence expression of a gene for growth differentiation factor 5 (GDF5), which is a protein involved in the development of cartilage in the legs and other long bones.

A team of researchers at Penn Sate has used an animal model to reveal, for the first time, a physiological basis for the effect of alcohol on male sexual behavior, including increased sexual arousal and decreased sexual inhibition.

The research in PLoS ONE resulted in four novel findings with broad importance for further addiction research. It is the first study to characterize the effects of chronic alcohol exposure in fruit flies. "Physiological evidence supporting various theories about the effect of alcoholic drinks has been lacking, so our now having a suitable animal model makes it possible to conduct much-needed laboratory research on this issue," explains research-team-leader Kyung-An Han, associate professor of biology and a neuroscientist at Penn State.

It's good news that we are living longer, but bad news that the longer we live, the better our odds of developing late-onset Alzheimer's disease.

Alzheimer's is a debilitating neurodegenerative disease that causes memory loss, dementia, personality change and ultimately death. The national Alzheimer's Association estimates that 5.1 million Americans are currently afflicted with the disease and predicts that the number may increase to between 11 million and 16 million people by the year 2050.

Many Alzheimer's researchers have long touted fish oil, by pill or diet, as an accessible and inexpensive "weapon" that may delay or prevent this debilitating disease.

The melodious sound of a songbird may appear effortless, but his elocutions are actually the result of rigorous training undergone in youth and maintained throughout adulthood. His tune has virtually “crystallized” by maturity. The same control is seen in the motor performance of top athletes and musicians. Yet, subtle variations in highly practiced skills persist in both songbirds and humans. Now, scientists think they know why.

Their finding, reported in the current issue of “Nature,” suggests that natural variation is a built-in mechanism designed to allow the nervous system to explore various subtle options aimed at maintaining and optimizing motor skills in the face of such variables as aging and injury.

Did you know even bacteria get old? Scientists traditionally assumed that bacteria were immortal, since these single-celled organisms split into two apparently identical daughter cells, which in turn divide, and so on. We now believe that this is not true. Eric Stewart of Northeastern University, and his colleagues took fluorescent images of individual E. coli cells over ten generations. Each generation the E. coli cells divide down the middle, giving each daughter cell one new tip and an old tip from its mother, or grandmother, or some older ancestor.
