Oxidative Stress is a condition in which antioxidant levels are lower than normal. Antioxidant levels are usually measured in blood plasma.

Increasing age, male sex and adiposity risk factors for metabolic syndrome in children

Metabolic syndrome is more likely to affect children who are obese than overweight or non-overweight and who have other characteristics associated with the disorder, such as high blood pressure or insulin resistance. A new comprehensive and systematic review of the medical literature on metabolic syndrome in children that probed deeper to evaluate the risk associated with gender, ethnicity, and geography was published in Metabolic Syndrome and Related Disorders, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers.

SOD1 enzyme protects cells by regulating cell energy and metabolism

Just like a comic book super hero, you could say that the enzyme superoxide dismutase (SOD1) has a secret identity. Since its discovery in 1969, scientists believed SOD1's only role was to protect living cells against damage from free radicals. Now, researchers at the Johns Hopkins Bloomberg School of Public Health have discovered that SOD1 protects cells by regulating cell energy and metabolism. The results of their research were published January 17, 2013, in the journal Cell.

Consuming carotenoid-rich foods may help prevent or delay onset of amyotrophic lateral sclerosis

New research suggests that increased consumption of foods containing colorful carotenoids, particularly beta-carotene and lutein, may prevent or delay the onset of amyotrophic lateral sclerosis (ALS).

Regular deep-fried food consumption may increase risk of prostate cancer

Regular consumption of deep-fried foods such as French fries, fried chicken and doughnuts is associated with an increased risk of prostate cancer, and the effect appears to be slightly stronger with regard to more aggressive forms of the disease, according to a study by investigators at Fred Hutchinson Cancer Research Center.

Stage IV cancer cells even more susceptible to grape seed extract than stage II

When the going gets tough, grape seed extract gets going: A University of Colorado Cancer Center study recently published in the journal Cancer Letters shows that the more advanced are colorectal cancer cells, the more GSE inhibits their growth and survival. On the other end of the disease spectrum, GSE leaves healthy cells alone entirely.

Scientists identify new mechanism for schistosomiasis-bladder cancer connection

About 200 million people across 75 of the poorest countries in the world are now infected by the blood parasite Schistosoma haematobium (S. haematobium). The infection causes severe urogenital disease, but also causes bladder cancer in a number of patients and why this occurs is not clear.

Blocking interaction of JNK enzyme may counteract neuron destruction

Oxidative stress is a primary villain in a host of diseases that range from cancer and heart failure to Alzheimer's disease, Amyotrophic Lateral Sclerosis and Parkinson's disease.

Ebselen effectively inhibits thioredoxin reductase system in H. pylori, M. tuberculosis

A drug currently being used to treat ischemic strokes may prove to be a significant advance in the treatment of tuberculosis and ulcers. In a new research report appearing online in The FASEB Journal, a compound called ebselen effectively inhibits the thioredoxin reductase system in a wide variety of bacteria, including Helicobacter pylori which causes gastric ulcers and Mycobacterium tuberculosis which causes tuberculosis.

Study investigates muscle weakness in mouse model of Down syndrome

It is well known that people with Down syndrome (DS) suffer from marked muscle weakness. Even the simple tasks of independent living, such as getting out of a chair or climbing a flight of stairs, can become major obstacles. This can reduce the quality of life for those with DS and lead to a loss of independence. Now, a new study sheds light on some of the suspected causes of muscle weakness.

Arginase, IDO could hold clues to help 79 million Americans with prediabetes

Two enzymes that are elevated in prediabetes could hold clues to helping the 79 million Americans with the condition avoid serious vascular complications and maybe even identify those most at risk for full-blown diabetes, researchers say.

Oncogene-induced senescence could play a key role in future cancer therapy

Cell aging, or cellular senescence, has an important role in the natural physiological response to tumor development. Activated oncogenes are able to induce senescence, and recent findings have suggested that oncogene-induced senescence (OIS) could play a key role in future cancer therapy.
