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.

Washington, Nov 4: Smaller mosquitoes are more likely to be infected with viruses that cause diseases in humans, according to a new study.

For the study, Barry Alto, Ph. D., Director of the Medical Entomology Program at the Illinois Natural History Survey, along with Assistant Professor Michael Reiskind of Oklahoma State University and Professor L. Philip Lounibos of the University of Florida fed mosquitoes blood with dengue virus and later tested them for infection.

The study was conducted at the Florida Medical Entomology Laboratory.

Mumbai, Nov 4 : The police have arrested three more suspects related to Malegaon blast which claimed six lives, officials said on Monday.

Ajay Eknath Rahirkar, Jagdish Chintamani Mhatre and Rakesh Dattaram Dhawade were arrested by the Anti-Terrorism Squad (ATS) on Sunday.

Earlier the ATS had arrested five people including god woman Pragya Singh and two retired army officials for their suspected involvement in the September 29 Malegaon blast in Maharashtra.

They were produced before a local court in Nasik on Monday.

"The three were produced in the Nasik court today and they have been granted police custody till November 10," Hemant Karkare, ATS chief, told reporters in Mumbai.

Washington, November 4 : A team of Italian and British researchers has found that nervousness, social isolation, or anxiousness during childhood protect young men from becoming criminal offenders until they enter adulthood.

Dr. Georgia Zara of the University of Turin and Dr. David Farrington of the University of Cambridge say that the protective effect seems to wear off after the age of 21.

Their findings are based on a study, published online in Springer’s Journal of Youth and Adolescence, which explored whether or not certain childhood factors delay the onset of criminal behaviour until adulthood.
