Curry pigment prevents alcohol-related liver disease in rats

Researchers have found that the yellow substance found in the pigment for curry prevents activation of a genetic factor leading to liver inflammation and necrosis. Despite numerous public education initiatives, alcohol abuse remains a leading cause of morbidity and mortality throughout the world. It is estimated that in the United States as many as 10 percent of men and three percent of women may suffer from persistent problems related to the use of alcohol. Alcohol affects many organ systems of the body, but perhaps most affected are the central nervous system and the liver. Almost all ingested alcohol is metabolized in the liver and excessive alcohol use can lead to acute and chronic liver disease.

Cell Density Determines Extent Of Damage Caused By Cigarette Smoke

First- or second-hand exposure to cigarettes can lead to a variety of diseases, including tissue destruction found in pulmonary emphysema and osteoporosis. Also included among cigarette smoking-induced diseases are disorders in which an excessive deposition of fibrotic scar occurs, such as with atherosclerosis and idiopathic pulmonary fibrosis. Collagen is the major protein of the white fibers found in connective tissue, cartilage, and bone.

Female Hormones Found To Protect Against Harmful Effects Of Fructose

A new study in female mice links estrogen, lower blood pressure, and insulin resistance, despite a high fructose diet. The experiments demonstrate that the effects of a fructose diet on metabolism and blood pressure are dependent on sex gender. Female rats are protected against fructose-induced hypertension, unlike their male counterparts, and the mechanisms responsible for this protection appear to be related to female sex hormones. Furthermore, there appears to be a sex difference in the vascular actions of insulin, which may also be involved in the mechanisms responsible for the sex differences observed in this experiment. The results of these experiments represent a novel finding into the interrelationship among hyperinsulinemia, insulin resistance, and hypertension. The potential existence of sex differences in this intriguing association might help elucidate the mechanisms involved and are worthy of further investigation.
