A NII-led team has unravelled how C. elegans exposed to early-life, moderate stress in the form of dietary restriction are able to better handle chronic stress that comes with ageing and thereby increase longevity. The small stress also helps delaying certain age-onset diseases such as Huntington’s and Alzheimer’s. The role of dietary restriction in delaying … Continue reading NII unravels how diet restriction delays ageing, increases lifespan

Cow dung makes cows susceptible to diseases and infection, leading to stress
Old, non-lactating cows housed in traditional cow shelters tend to have higher stress when among other factors there is cow dung in places where the cows lie down and there is no access to open yards. The study says cow dung makes cows dirtier, and susceptible to diseases and infection, leading to stress. CCMB team … Continue reading Cow dung makes cows susceptible to diseases and infection, leading to stress
Human disturbances stress Indian tigers, may reduce fertility
CCMB researchers in collaboration with a Russian team have found that Bengal tigers in three India tiger reserves are 20% more stressed. The stress is caused due to higher anthropogenic disturbances from tourists and visitors and higher population density. Elevated stress in tigers can negatively impact reproductive hormones leading to reduced fertility and reproductive failure. … Continue reading Human disturbances stress Indian tigers, may reduce fertility
IICB team deciphers the molecular mechanism of stress-induced gastric ulcer
Researchers at Kolkata’s IICB have for the first time identified the molecular mechanism by which acute mental stress affects the stomach causing gastric ulcer or stress-related mucosal disease. Since acute mental stress damages the mitochondria of the stomach causing tissue injury and haemorrhage, two drugs that target the mitochondria were able to prevent damage thus avoiding … Continue reading IICB team deciphers the molecular mechanism of stress-induced gastric ulcer
Improving access to mental health services in remote areas
While about 10% of the population in India suffers from common mental disorders, only about 15-25% of this receives mental health care. But a small-scale study carried out on approximately 5,000 people living in 30 tribal villages in West Godavari district of Andhra Pradesh was able to improve the practice of seeking out mental health … Continue reading Improving access to mental health services in remote areas
Iceland knows how to stop teen substance abuse but the rest of the world isn’t listening
In Iceland, teenage smoking, drinking and drug use have been radically cut in the past 20 years. Emma Young finds out how they did it, and why other countries won’t follow suit. It’s a little before three on a sunny Friday afternoon and Laugardalur Park, near central Reykjavik, looks practically deserted. There’s an occasional adult … Continue reading Iceland knows how to stop teen substance abuse but the rest of the world isn’t listening
NCBS researchers find a biomarker for stress-induced memory loss
Timely intervention to prevent or delay hippocampus-linked memory loss that occurs as a result of chronic stress may now be possible, thanks to the discovery of a biomarker — a reduction in hippocampal volume at an early time point after the onset of chronic stress. The reduction in the hippocampal volume is not only linked … Continue reading NCBS researchers find a biomarker for stress-induced memory loss
Cardiovascular risk factors low but mortality high in India
People living in low-income countries like India, Pakistan, Bangladesh and Zimbabwe have the lowest risk factors for cardiovascular diseases (CVD) compared with those living in high-income countries like Canada, Sweden and the United Arab Emirates. Yet, the rate of deaths from CVD is highest in the low-income countries, not in the high-income countries. The risk … Continue reading Cardiovascular risk factors low but mortality high in India
Even lower stress levels can increase risk of cardiovascular deaths, says study
Published in The Hind on August 1, 2012 People suffering from even low, subclinical levels of psychological stress are at an increased risk of death from external causes and cardiovascular diseases, says a study published today (August 1) in the British Medical Journal (BMJ). The increased risk of death from both external causes and cardiovascular … Continue reading Even lower stress levels can increase risk of cardiovascular deaths, says study
