(Press-News.org) The prevalence of type 2 diabetes is dramatically increasing throughout the world. Insulin resistance is a hallmark of type 2 diabetes, and it most often precedes the onset of hyperglycemia and predicts development of type 2 diabetes. At present, thiazolidinediones (TZD), the agonists of the peroxisome proliferators-activated receptor γ, are the main agents to improve insulin sensitivity in the liver, adipose tissue, and skeletal muscle, thus improving glycaemic control in patients with type 2 diabetes. Despite the efficacy, some deleterious side effects of TZDs, including rosiglitazone and pioglitazone, have been noted, such as increasing body weight and aggravating heart failure through fluid retention. Therefore, development of new agents may be helpful in the treatment of type 2 diabetic patients with insulin resistance.
A research article published on February 28, 2011 in the World Journal of Gastroenterology addresses this question. The research team led by Professor Wen-Jian Wang from Institute of Chinese Integrative Medicine, Huashan Hospital of Fudan University investigated the effect of the Chinese herbal decoction, Yi-Qi-Zeng-Min-Tang (YQZMT), on insulin resistance in type 2 diabetic rats.
The results of this study indicated that YQZMT has beneficial effect in insulin resistance, glycaemic control, dyslipidemia, free fatty acids and adipocytokines, and does not cause any increase in body weight in high-fat diet and low-dose streptozotocin induced type 2 diabetic rats.
The findings demonstrate that YQZMT displays the insulin sensitization characteristic of rosiglitazone, but unlike rosiglitazone, does not cause any increase in body weight. Administration of YQZMT may be a suitable adjunct for the treatment of insulin resistance patients. Further studies will be required to identify the ingredients and chemicals in YQZMT responsible for the beneficial effects observed in the present study.

City-data.com is a website that lists statistics about American cities and towns. Recently, I spent some time looking at the numbers for Prescott and Prescott Valley. I can't really tell you why I decided to check up on Yavapai County, but I did and what I found out led me to some interesting thoughts regarding bankruptcy in Prescott. Whenever I look at bankruptcy in an area I start off by diving into the data relating to housing and income. Prescott has a fairly low median income for Arizona at $41,010 where as Arizona as a whole has a median income of $48,745. This in ...
Impairment of oral intake occurs in the majority of patients with head and neck cancer (HNC) receiving chemoradiotherapy. Placement of prophylactic percutaneous endoscopic gastrostomy (PEG) tube in asymptomatic newly diagnosed HNC before chemoradiation is a common practice in some centers. In some studies, PEG has been associated with a decrease in treatment related weight loss in patients with HNC, but no studies have examined the utilization rate.

Its head looks like a turkey's, its body resembles a chicken's – now scientists can explain why one of the poultry world's most curious specimens has developed such a distinctive look.
The Transylvanian naked neck chicken – once dubbed a Churkey or a Turken because of its hybrid appearance – has developed its defining feature because of a complex genetic mutation.
Researchers at The Roslin Institute at The University of Edinburgh found that a vitamin A-derived substance produced around the bird's neck enhanced the effects of the genetic mutation.
This causes a protein ...
Traditionally, both air and tap water have been used as oral contrast agents to achieve adequate gastric distension for preoperative computed tomography (CT) imaging in patients with early gastric cancer (EGC). Despite introduction of multi-detector row CT techniques and the use of multiplanar reconstruction (MPR) images, the detection rate of EGC on hydrostomach CT has still been unsatisfactory.
A research article published on February 28, 2011 in the World Journal of Gastroenterology addresses this question. The authors conducted a comparison study for the detection ...
Colonoscopy is considered a safe procedure, although complications can occur. The most dreaded of these is iatrogenic perforation. The literature reports perforation rates of 0.03%-0.8% for diagnostic procedures, and a rate of 0.15%-3% for therapeutic procedures. Mechanisms of perforation are the result of either mechanical disruption of the colonic wall (e.g. thermal injury, forced push into a diverticulum, or stretching of the bowel with loops or the slide-by technique) or excessive air insufflation. After perforation, prompt abdominal surgery is usually recommended, ...
In a unique collaboration between scientists from the UK, Ecuador and Réunion, a new species of yeast has been discovered growing on the fruit of an unidentified and innocuous bramble collected from the biodiversity-rich Maquipucuna cloud forest nature reserve, near Quito, in Ecuador.
"We are actively looking for new yeasts with the ability to ferment plant material to produce bio-energy," said Dr Steve James from the National Collection of Yeast Cultures at the Institute of Food Research in Norwich.
The collection of yeasts at the institute is already used for bread ...
University of Manchester scientists have led an international team to discover new treatments for a rare and potentially lethal childhood disease that is the clinical opposite of diabetes mellitus.
Congenital hyperinsulinism (CHI) is a condition where the body's pancreas produces too much insulin – rather than too little as in diabetes – so understanding the disease has led to breakthroughs in diabetes treatment.
This latest study, published in the journal Diabetes today (Wednesday), was carried out with clinical colleagues at hospitals throughout Europe and at the ...
Recently the West Valley View, the newspaper serving the communities of Avondale, Buckeye, Goodyear, Litchfield Park, and Tolleson ran an article on the tough economic times Arizona as a whole can look forward to over the next few years. Sadly, most Arizona residents had already come to this realization. The combination of the bursting of the massive housing bubble in Arizona and current rock-bottom housing values has left a look of people in a valueless house. Sprinkle in a dose of high unemployment and suddenly you have the making of a housing crisis.

INDIANAPOLIS – Stroke patients who are not successfully treated for depression are at higher risk of losing some of their capability to function normally, according to a study in the March 15, 2011 issue of the journal Neurology.
Although as many as a third of those who experience a stroke develop depression, a new study by researchers from the Regenstrief Institute, the schools of health and rehabilitation sciences and of medicine at Indiana University-Purdue University Indianapolis and the Richard L. Roudebush VA Medical Center is the first to look whether managing ...
It is difficult to write a letter on a driving bus, or to measure small distances on a vibrating plate – the vibrations simply interfere too much. Any small vibration coming from the floor is already too much if there is an increased requirement with respect to accuracy. They hamper high-resolution measurements of distance or roughness – as in scanning electron microscopy. They are also not desired in production if precision is a requirement. For this reason, the devices must be settled in such a manner that they are stable and quiet. Damping is necessary also when the ...
