HIV's secret life in gut revealed

One of the first things HIV does when it first enters the body is mess up the gut. Now, the open access journal PLOS Pathogens reports the first 3D ultra-structural study of the human immunodeficiency virus in a live host.The human gut has the highest concentration of HIV target immune cells, most of which the virus destroys within days of infection.

Antioxidants may speed up lung cancer progression

Numerous studies have shown that antioxidants may halt cancer progression. But a new study from researchers at the Sahlgrenska Academy at the University of Gothenburg in Sweden has found that antioxidants may actually speed up the progression of lung cancer.The findings are published in the journal Science Translational Medicine.

Thirdhand smoke linked to liver, lung and skin problems

While the physical evidence of secondhand smoke can be seen wafting through the air, thirdhand smoke is a more clandestine health threat. The invisible remnant of tobacco smoke that clings to surfaces and even dust, thirdhand smoke is linked to several adverse health effects in a new study published in PLOS ONE.

Stem cell source found in tissue discarded in hip replacements

Tissue that is typically discarded in routine hip replacement operations may offer a rich untapped source of stem cells that could be banked for later use in regenerative medicine, where patients' own cells are used to treat disease or repair failing organs.

Vodka confirmed as major factor in early death of Russian men

A large study shows that alcohol - and, in particular, vodka - is responsible for Russia's high and sharply fluctuating death rates. Russia currently has an abnormally high early death rate in men - 25% of all Russian men will die before the age of 55.One of the authors of the new study, Prof.

Obesity starts in kindergarten, study suggests

Researchers from Emory University in Atlanta, GA, conducted a study that suggests children who are overweight or obese by kindergarten are four times more likely to be obese in eighth grade, compared with their normal-weight counterparts. Focusing obesity-prevention efforts on younger children may be important, the team says.Led by Solveig A.

Metabolic syndrome linked to poor breakfast habits in childhood

Researchers in Sweden report a link between incidence of metabolic syndrome in adults and the kind of breakfasts those adults ate as children.There is a lot of evidence that breakfast really is "the most important meal of the day.

New study finds link between slow reaction time and early death

A new study, published in the journal PLOS ONE, has found that adults who have slow reaction times have a higher risk of an early death.Reaction time was studied because it reflects how well the central nervous system is working. It also reflects basic mental skills, such as how quickly a person is able to process information.

Exposure to peanuts builds immunity in allergic children

With the caveat that this should not be tried at home, researchers conducting a study in children with peanut allergies found that the participants could build up a tolerance by consuming increasingly larger amounts of peanut protein on a regular basis.The technique, called oral immunotherapy (OIT), was used as part of the STOP II trial, results of which are published in The Lancet.

Vitamin D supplements: are they really good for our health?

There is no doubt that our bodies need vitamin D. It helps regulate the absorption of calcium and phosphorus in our bones, helps our cells to communicate with each other, and helps strengthen our immune system. But can vitamin D supplementation really offer additional health benefits?Previous research suggests it can.

Stress reduces when shared

Diabetes and high estrogen levels raise dementia risk for women

New research suggests that older women who have both high estrogen levels and diabetes have a significantly higher risk of dementia, compared with older women who do not have these combined conditions. This is according to a study published online in Neurology.

Popularity of indoor tanning among younger people 'alarming'

New research analyzing the prevalence of indoor tanning has revealed the activity is very common in Western countries, particularly among young people. Because the use of tanning beds has been associated with a higher risk of skin cancers, researchers say its popularity is a public health risk.Indoor tanning exposes the user to ultraviolet (UV) radiation.

Breakthrough: Scientists create embryonic stem cells without embryos

Researchers from Brigham and Women's Hospital, in collaboration with researchers from Japan, have discovered a way of changing adult stem cells back to their original embryonic state by exposing them to low oxygen and acidic environments. This is according to a study recently published in the journal Nature.The research team, including senior author Dr.

Adrenal tumors: hormone secretion linked to cardiovascular events

New research suggests that patients with adrenal tumors that secrete a hormone called cortisol are at higher risk of suffering cardiovascular events and increased mortality. Investigators say their findings may lead to better clinical management of patients with these tumors.This is according to a new study published in The Lancet Diabetes & Endocrinology.
