Zinc can halt the growth of cancer cells, study says Zinc supplements can significantly inhibit the proliferation of esophageal cancer cells, according to a new study co-authored by a University of Texas at Arlington researcher. Previous studies had shown that zinc is essential for maintaining human health and protects the esophagus from cancer. However, it has never been fully understood why zinc has the ability to prevent cancer in the esophagus. In this study, a team led by Zui Pan, an associate professor of nursing at UTA's College of Nursing and Health Innovation and a noted esophageal cancer researcher, discovered that zinc selectively halts the growth of cancer cells but not normal esophageal epithelial cells. The finding was published this month in The FASEB Journal , the official journal of the Federation of American Societies for Experimental Biology. Esophageal cancer is the sixth leading cause of human cancer deaths around the world, according to the Nation...

Vitamin C Can Reduce High Blood Pressure, Study Finds CORVALLIS, Ore. - Researchers have discovered that a 500 milligram daily supplement of vitamin C can significantly reduce high blood pressure in hypertensive patients. The study, published this month in the medical journal Lancet, was done by scientists at the Boston University School of Medicine and the Linus Pauling Institute at Oregon State University. It was supported by the National Heart, Lung and Blood Institute of the National Institutes of Health. "Hypertension is a serious health problem in much of the world," said Balz Frei, professor and director of the Linus Pauling Institute, and a co-author of the research along with principal investigator Dr. Joseph Vita at Boston University. "It's a key risk factor in heart disease and strokes." "We believe this is a significant finding that may be of considerable value to patients who have moderately elevated blood pressure," Frei s...
Fatty acid increases performance of cellular powerhouse Mitochondria are essential to all higher forms of life. Every animal and plant depends on these small intracellular structures. Mitochondria have multiple tasks: Since they generate most of the cell's biochemical energy, they are referred to as the powerhouses of the cell. In addition, they are responsible for producing and breaking down amino acids and fats. They also regulate cellular death, called apoptosis. As a result, the spectrum of diseases that are linked to mitochondrial defects is wide, ranging from severe muscular and nervous disorders to neurodegenerative diseases as well as all symptoms of aging. "It was by pure chance that we discovered this completely new control mechanism of mitochondrial function," says first author Deniz Senyilmaz, who works in Aurelio Teleman's group at the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ). In collaboration with colleagues fr...
