Increase In Visceral Fat During Menopause Linked With Testosterone
http://www.sciencedaily.com/releases/2009/08/090820161144.htm
In middle-aged women, visceral fat, more commonly called belly fat, is known to be a significant risk factor for cardiovascular disease, but what causes visceral fat to accumulate?
The culprit is likely not age, as is commonly believed, but the change in hormone balance that occurs during the menopause transition, according to researchers at Rush University Medical Center.
"Of all the factors we analyzed that could possibly account for the increase in visceral fat during this period in a woman's lifetime, levels of active testosterone proved to be the one most closely linked with abdominal fat," said Imke Janssen, PhD, assistant professor of preventive medicine and the study's lead investigator.
The study, which has been published early online in the medical journal Obesity, included 359 women in menopausal transition, ages 42 to 60, about half black and half white. Fat in the abdominal cavity was measured with CT scans, a more precise measurement than waist size. Blood tests were used to assess levels of testosterone and estradiol (the main form of estrogen). Medical histories covered other health factors possibly linked with an increase in visceral fat.

Screening of herbal extracts for activation of the human peroxisome proliferator-activated receptor

The peroxisome proliferator-activated receptors play a pivotal role in metazoan lipid and glucose homeostasis. Synthetic activators of PPARalpha (fibrates) and PPARgamma (glitazones) are therefore widely used for treatment of dislipidemia and diabetes, respectively. There is growing evidence for herbal compounds to influence nuclear receptor signalling e.g. the PPARs. We recently reported carnosic acid and carnosol, both being diterpenes found in the labiate herbs sage and rosemary, to be activators of PPARgamma. The subsequent screening of a variety of ethanolic extracts, obtained from traditionally used herbs, for PPAR activation, led to an exceptionally high hit rate. Among 52 extracts nearly the half significantly activated PPARgamma and 14 activated PPARalpha in addition, whereas three of them were pan-PPAR activators, which also activated PPARdelta. The most active extracts, for which a concentration dependent effect could be shown, were the extracts of Alisma plantago aquatica (ze xie/european waterplantain), Catharanthus roseus (madagascar periwinkle), Acorus calamus (sweet calamus), Euphorbia balsamifera (balsam spurge), Jatropha curcas (barbados nut), Origanum majorana (marjoram), Zea mays (corn silk), Capsicum frutescens (chilli) and Urtica dioica (stinging nettle). The results of the present study provide a possible rationale for the traditional use of many herbs as antidiabetics.

Anti-diabetic medication
Drugs used in diabetes treat diabetes mellitus by lowering glucose levels in the blood. With the exceptions of insulin, exenatide, liraglutide and pramlintide, all are administered orally and are thus also called oral hypoglycemic agents or oral antihyperglycemic agents. There are different classes of anti-diabetic drugs, and their selection depends on the nature of the diabetes, age and situation of the person, as well as other factors.
Diabetes mellitus type 1 is a disease caused by the lack of insulin. Insulin must be used in Type I, which must be injected.
Diabetes mellitus type 2 is a disease of insulin resistance by cells. Type 2 diabetes mellitus is the most common type of diabetes. Treatments include (1) agents that increase the amount of insulin secreted by the pancreas, (2) agents that increase the sensitivity of target organs to insulin, and (3) agents that decrease the rate at which glucose is absorbed from the gastrointestinal tract.
Several groups of drugs, mostly given by mouth, are effective in Type II, often in combination. The therapeutic combination in Type II may include insulin, not necessarily because oral agents have failed completely, but in search of a desired combination of effects. The great advantage of injected insulin in Type II is that a well-educated patient can adjust the dose, or even take additional doses, when blood glucose levels measured by the patient, usually with a simple meter, as needed by the measured amount of sugar in the blood.
