Research on nerve cell circuitry reveals clue about schizophrenia
...gues injected the RGS4 protein in a nerve cell and measured "calcium current," a marker for the levels of neurotransmitters released by nerve cells. They found that the protein increased levels of neurotransmitter, suggesting that RGS4 helps nerve cells communicate better with each other. Their study of nerve...Location of body fat important in predicting heart attack risk
...g. At the beginning of the study, the researchers measured total body fat as well as fat distribution (waist-to-thigh ratio, waist circumference, and intra-abdominal or visceral fat). Participants were contacted every six months for the next 4 years to collect data about hospitalizations or major outpatient ...Exercise for special populations, sensory research, factors impacting rehabilitation top issues

Although prosthetic gait with the prototype showed no significant variation in individuals at different speeds, volunteers had increased stability and ease of swing with the prototype.

While the training input arrives simultaneously from the glove and the muscles, the "self-learning" computer integrates this informati...Marijuana-like compounds may aid array of debiliating conditions ranging from Parkinson's to pain
...lowing the onset of disease signs. The researchers measured disease progression by testing how long the mice could stand on a slowly rotating rod. The more severe their nerve cell degeneration, the less time the mice can balance on the rod. In addition, two conditions of ALS, the loss of movement ability and ...New insights into hormone therapy highlight when estrogen best aids brain

Because mice have a natural tendency to explore novel objects, mice with good memory for the original objects should spend more time examining the new object. Again, mice in the control and continuous...Sleep disorders often indicate multiple health conditions

Following treatment with continuous positive airway pressure (CPAP), the average ESS score for patients with sleep apnea improved significantly, from 11.6 to 2.7, and th......fficacy of only 10%. However, the immune response, measured one week after the third vaccination, was 80 times higher in the DNA/MVA vaccine group than in the rabies vaccine group.

The investigators then measured levels of CREB phosphorylation, a measure of cellular tolerance to stress and of the ability to generate memory under situations of hypoxia, in different brain region.

In addition, the researchers say, they found that as dietary fat intake increased in the women studied, so did the hormone levels.
