Nitric Oxide Levels In Brain Indicate Sleep

...decline. Rosenberg had been studying how the brain regulates the accumulation of adenosine in the brain for over 10 years, and, in 2000, he and his colleagues demonstrated in brain cells from rats that adenosine's release is stimulated by nitric oxide. The two teams decided to collaborate. Studying mildly sl...

Study States That CNS Could Regulate Arthritis

...ed p38 MAP kinase throughout the body. This enzyme regulates cytokines proteins released in response to stress that regulate inflammation in patients with arthritis. p38 is known to regulate production of a one particular cytokine called TNF??, and inhibitors of this cytokine are effective therapies for rheuma...

Drugs Activating PXR May Help In Treating Niemann-Pick type C disease

...e X receptor (PXR). Found in the cell nucleus, PXR regulates the activity of a cluster of genes that helps the body get rid of toxins. NPC affects approximately one in every 100,000 children. Affected individuals typically present in early childhood with gait disturbance and progressive impairment of motor ...

Committee Set Up to Review Safety of CT Scans

...due to report in 2007." She also said that "DoH regulates medical exposures to ionizing radiation, such as x-rays or CT scans, to ensure that the long-term benefits to the individual outweigh possible risks associated with radiation." The medical fraternity is divided about the issue with some doctors sa...

Processed foods – "the" cause of obesity!

...tion, which in turn floods the hypothalamus, which regulates energy use in the body.In this way, insulin blocks the path of another hormone, leptin, which tells the brain about the energy requirement. This ends up in the body going into starvation mode -- the brain thinks it isn't getting enough energy, so it ...

Wear and Tear of Stress: The Psychoneurobiology of Aging

...speaking or perceptions of social status) and then regulates the behavioral and physiological responses through the autonomic, immune and neuroendocrine systems. If the brain is under too much stress for too long, said McEwen, “we can see structural and functional remodeling changes that affect how it function...

Surgeries Performed In The Morning Have Less Post-Op Complications

...ough a drop in its natural circadian rhythm, which regulates sleep, brain wave activity and other bodily functions. The researchers also stated that they were planning to conduct another study to compare steps in the delivery of care for patients having surgery during two time periods - 9am to noon and 3pm t...

CLA Compounds Fight Diabetes

... of the protein, which then interacts with DNA and regulates gene expression. This increases the enzymes that process fatty acids and also increases the tissues' sensitivity to insulin. "We wondered if CLA was using the same mechanism, in which case it could be used as an anti-diabetes drug," Vanden Heuvel s...

Obsessive-Compulsive Disorder Is Familial

...A1. The gene encodes a protein called EAAC1 that regulates the flow of a substance called glutamate in and out of brain cells. So, variations in the gene might lead to alterations in that flow, perhaps putting a person at increased risk of developing OCD. The new findings are especially important not only ...

Atherosclerosis and its Mechanics

...mining the role of JNK in many diseases because it regulates the expression of genes involved in programmed cell death, tumor genesis, and other stress responses. Atherosclerosis, the collection of deposits such as cholesterol along artery walls, accounts for nearly 75 percent of deaths from cardiovascular d...

Study Says - Blocking 'aP2' Protein Prevents Airway Diseases

...ng protein in human airway epithelial cells// that regulates the allergic airway inflammation. The researchers had explained in their study that the adipocyte/macrophage fatty acid–binding protein aP2, which is known to regulate the uptake by fat cells of fatty acids and has been previously linked to insul...

Same Genes Act Differently in Males and Females

...e genetic code, but our findings imply that gender regulates how quickly the body can convert DNA to proteins," said Yang. "This suggests that gender influences how disease develops." The gender differences in gene expression also varied by tissue. Affected genes were typically those most involved in the org...

Genetic Mutation in Mice Suggests Extinct Mammoth Had Light and Dark Fur

...ation in the melanocortin-1 receptor, a gene which regulates the pigmentation of hair color. In laboratory mating of the different subspecies to produce genetic crosses, the UCSD scientists report in their paper that the variations of this gene account as much as 36 percent of the color variation in Gulf Coa...

Britain Gets Wonder Drug That Busts Fats

... obesity medications. The endocannabinoid system regulates the appetite and Rimonabant works by blocking molecular receptors, which on activation, can trigger a cascade of biological events affecting food intake and energy use, as well as fat and glucose metabolism. Dr Haslam, a GP from Hertfordshire said,...

Growth Hormone Stimulants help to Combat Aging Symptoms

...ect physical function throughout our lives, and it regulates metabolism and body composition. As adults move into middle age, growth hormone production begins to taper off. Many of the effects of aging – increased abdominal fat, reduced muscle mass, and decreased physical function – look very similar to the sy...

Antibacterial Products Ensure Food Safety and Health

...true genetic mutation. Withdrawal time – The FDA regulates the period of time in which an antibiotic cannot be administered to animals prior to milk or egg collection or slaughter of the animal for human consumption. Withdrawal times are designed to ensure that no unsafe concentration of drug residue is pres...

Fat Cell Hormone Could Trigger Diabetes, Heart Disease

...lar risk factors. ADIPO is known as a hormone that regulates the metabolism of lipids and glucose. It influences how the body responds to insulin and it also has antiinflammatory effects on the cells lining the walls of blood vessels. While high blood levels of adiponectin have been associated with reduced ri...

Repeated Liver Cell Proliferation, a Cause for Liver Cancer

...ancer is known to involve the NF-kB pathway, which regulates gene expression. In research published in the journal Cell in 2005, Karin and his colleagues at UCSD implicated the pathway's activator, IKK , in chemically induced liver cancer. However, the surprising outcome of those studies was the finding that w...

Schizophrenia Complicates With Altered Receptor Activity

... Thus found a link between 2 receptor groups, that regulates a mechanism for decreased NMDA receptor function usually seen in schizophrenic patients. Schizophrenia, a mental disorder afflicting approximately one percent of the world population, is characterized by a variety of symptoms such as: hallucination...
