Washington, Nov 4: While hip resurfacing is considered to be the modern day alternative for total hip replacement, researchers at Rush University Medical Center have suggested that the procedure is not ideal for everyone - and a patient''s age and gender is the key to the operation''s success.

For the study, the scientists examined data for 537 hip resurfacing surgeries performed in the U. S. using a hip resurfacing device, called the Birmingham Hip Resurfacing implant, recently approved by the Food and Drug Administration (FDA),

They found that the majority of serious complications occurred in women of all ages and men over the age of 55.

Lahore, Nov 4: Former Pakistan cricket captain Aamir Sohail is soon likely to take over as the Chief Selector of the national cricket team, reliable PCB sources have stated.

The current selection committee, under the lead of Saleem Jafar which had the responsibility to select players of Abu Dhabi series, was temporary and would be dissolved after the series against West Indies, The News quoted the sources as saying.

Former captain Aamir Sohail is a strong frontrunner for the post, the sources said and added that he has been offered the post by PCB.

Meanwhile, if he takes up the new job, Sohail would have to bid fare well to commentary assignments.

Washington, Nov 4: A new study by researchers at the University of California San Diego, La Jolla, has revealed that brains of individuals with major depressive disorder appear to react more strongly when anticipating pain and also display altered functioning of the neural network that modifies pain sensitivity.

"Chronic pain and depression are common and often overlapping syndromes," the authors said.

Washington, Nov 4 : A new study has found that kids and adults living with adult smokers appear less likely to have daily access to enough healthy food compared with those living with non-smoking adults,

Previous studies have shown that food insecurity is strongly linked to household income.

Since families with at least one smoker spend 2 percent to 20 percent of their income on tobacco, it is likely that smokers are affecting the financial resources needed to provide adequate food.

Washington, Nov 4: A single allele of tumour suppressor genes is enough to put a person at risk of cancer, according to a new study.

In the study focussing on SMAD4, a tumour suppressor gene implicated in pancreatic and colorectal cancer, the researchers found that such genes don’t really need both alleles to be knocked out before disease phenotypes are expressed.

Led by Riccardo Fodde from Erasmus MC, Rotterdam, the researchers found that only one allele of SMAD4 has to be damaged to put a person at risk of pancreatic and colorectal cancer.

They found that having one mutated SMAD4 allele was associated with the development of gastrointestinal polyps.

Washington, Nov 4 : Researchers at the University of Cincinnati (UC) have discovered a gene that helps control the secretion of acid in the stomach.

According to researchers, this information could one day aid scientists in creating more efficient treatment options for conditions such as acid reflux or peptic ulcers.

During the study, UC professor Manoocher Soleimani, MD, and colleagues found that when transporter Slc26a9 – the gene responsible for the production of chloride in the stomach – is eliminated from the mouse model''s system, acid secretion in the stomach stops.

Gastric acid, comprised mainly of hydrochloric acid (HCL), is the main secretion in the stomach and helps the body to break down and digest food.
