Washington, Oct 29 : Lung regeneration – an advance that could effectively treat millions of people suffering from respiratory disorders – could soon be a reality, thanks to a new discovery by researchers at Weill Cornell Medical College.
The research team said that they have uncovered the biochemical signals in mice that trigger generation of new lung alveoli, the numerous, tiny, grape-like sacs within the lung where oxygen exchange takes place.
Specifically, the regenerative signals originate from the specialized endothelial cells that line the interior of blood vessels in the lung.
Washington, Oct 25 : Taking blood pressure pills at bedtime not only controls blood pressure more efficiently but also lowers the risk of heart problems, a new study has suggested.
The results indicate that heart conditions such as strokes and heart attacks can be drastically reduced in patients with hypertension with no extra effort or cost.
Ramon Hermida, PhD (University of Vigo, in Spain) and his colleagues studied the impact of taking blood pressure medications at different times of the day, on health, in a group of 661 patients who had chronic kidney disease and hypertension.
Washington, Oct 24 : Women who do shift work may be at increased risk of heart disease, according to a new study.
Women hospital staff working night shifts may be compromising their own health as they try to improve the health of patients, said Dr. Joan Tranme who investigated the connection between shift work and risk factors for heart disease in female hospital employees, who worked both shift and non-shift rotations.
Washington, Oct 24 : A new study has found that postmenopausal women who used nonsteroidal anti-inflammatory drugs for at least 10 years had a lower risk for death from colorectal cancer compared with women who do not these drugs.
“Our results suggest that nonsteroidal anti-inflammatory drug (NSAID) use is associated with lower colorectal cancer mortality among postmenopausal women who use these medications more consistently and for longer periods of time,” said Anna E. Coghill, M. P. H., a doctoral student in Epidemiology at the University of Washington and Fred Hutchinson Cancer Research Centre.
Washington, Oct 24 : Researchers have revealed that an antiparasitic agent used to treat African sleeping sickness might someday be used to prevent nonmelanoma skin cancers.
They found that DFMO, or a-difluoromethylornithine, continue to protect against nonmelanoma skin cancers years after people stopped taking the drug.
In this follow-up study, researchers evaluated prolonged evidence of a protective effect of DFMO among 209 people who had participated in an earlier study.
Washington, Oct 24 : Heavy alcohol consumption may increase the risk of developing lung cancer, while higher BMI and increased consumption of black tea and fruit could reduce the risk of the deadly disease, a new research has suggested.
The researchers studied 126,293 people who provided baseline data from 1978 to1985 and followed them until 2008 to determine their risk for developing lung cancer in relation to cigarette smoking, alcohol consumption, gender, ethnicity, BMI, and level of education.
Washington, Oct 24 : Sleeping less than 8 hours a night may be lead to weight gain in teens, a new study led by an Indian-origin researcher has found.
Furthermore, obesity is linked to short sleep duration in teenage boys, with the fewest hours slept linked to the highest BMI levels, the report said.
“Sleep is food for the brain. When teens do not get enough sleep, they fall asleep in class, struggle to concentrate, look and feel stressed, get sick more often, and do not meet their obligations due to tiredness,” said study author Lata Casturi, MA, RPSGT, Baylor College of Medicine Sleep Center in Houston, Texas.
Washington, Oct 24 : An Indian study has found that a new treatment that includes playing video games along with standard therapy could help correct amblyopia, also called “lazy eye” in older children.
Dr. Somen Ghosh found that his new approaches allowed about a third of the study participants, who were between 10 and 18 years old, achieved significant vision gains.
By the end of the one-year study conducted in an eye clinic in India, nearly 30 percent of the 100 participants achieved significant vision gains.
About 60 percent showed at least some improvement.
Washington, Oct 24 : Changing your diet might actually do a better job to lower your cholesterol than cholesterol-lowering drugs called statins, which can sap your energy and cause problems for your sex life, according to a new study.
A nutrient-poor diet filled with added sugars and unhealthy trans fats is understood to cause high cholesterol, so healthy food, like fruits, vegetables and nuts might help better fix the problem, the study said.
The researchers followed 345 people with high cholesterol who were placed on one of two vegetarians, low-cholesterol diets for six months.
Washington, Oct 24 : Use of a special femtosecond laser can make cataract surgery safer and more efficient than today’s standard procedure, a new study has suggested.
The release relates to research reported by William J. Culbertson, MD, of the University of Miami, and Mark Parker, MD, of Oregon Health and Sciences University, at the annual meeting of the AAO.
Culbertson’s team studied how pre-treating cataracts with the femtosecond laser affected the level of ultrasound energy needed to soften the cataracts.
Washington, Oct 24 : Postmenopausal women who gain weight during adulthood are at an increased risk for endometrial cancer compared with women who maintain a stable weight, according to a new study.
Victoria L. Stevens, Ph. D., strategic director of laboratory services at the National Home Office of the American Cancer Society in Atlanta, and colleagues investigated whether adulthood weight gain and/or weight cycling, defined as the number of times a woman purposefully lost 10 pounds or more and then later regained the weight, increased the risk for endometrial cancer in postmenopausal women, independent of body mass index (BMI).
Washington, Oct 21 : Researchers at UCLA have, for the first time, found that the connections between brain regions that are important for language and social skills, grow much more slowly in boys with autism than in non-autistic children - a possible explanation for why autistic children act and think differently than their peers.
They found aberrant growth rates in areas of the brain implicated in the social impairment, communication deficits and repetitive behaviours that characterize autism.
Normally, as children grow into teenagers, the brain undergoes major changes.
Washington, Oct 21 : Men who experience persistently moderate or high levels of stressful life events over a number of years have a 50 percent higher mortality rate, according to a new study.
In general, the researchers found only a few protective factors against these higher levels of stress – people who self-reported that they had good health tended to live longer and married men also fared better.
Moderate drinkers also lived longer than non-drinkers.
Washington, Oct 21 - If you want to live longer, keep your stress to a minimum, get married and have a glass of wine every night, new research says.
Researchers found that people who self-reported that they had good health tended to live longer. Moderate drinkers also lived longer than non-drinkers.
"Being a teetotaller and a smoker were risk factors for mortality," said Carolyn Aldwin, professor of human development and family sciences at Oregon State University, who led the study.
Men who experience moderate or high levels of stress over a number of years have a 50 percent higher mortality rate, the Journal of Aging Research reports.
Washington, Oct 21 : Danish scientists have claimed that prolonged usage of mobile phones is not linked with the risk of brain tumours and have clearly contradicted many of the studies on the same subject published earlier.
In what is described as the largest study on the subject till date, Danish researchers found no evidence that the risk of brain tumours was raised among 358,403 mobile phone subscribers over an 18-year period.
