Can teenagers' relationship with their mother protect them from the negative effects that television has on their sexual attitudes? It depends on their gender, according to a new study by Laura Vandenbosch and Steven Eggermont, from Katholieke Universiteit Leuven in Belgium. For girls, a good relationship with mom is protective. For boys, however, a strong attachment to mom increases the likelihood that they will have stereotypical sexual attitudes, as portrayed on television. The work is published online in Springer's journal Sex Roles.

Scientists from the Faculty of Biology and Biotechnology at the RUB have published a report in the Journal of Biological Chemistry explaining why enzymes used for the production of hydrogen are so sensitive to oxygen. In collaboration with researchers from Berlin, they used spectroscopic methods to investigate the time course of the processes that lead to the inactivation of the enzyme's iron center.
Bethesda, MD—If you smoke cigarettes, you have more in common with someone who has cystic fibrosis than you think. A new research report appearing online in the FASEB Journal (http://www.fasebj.org) shows that smoking cigarettes affects the lungs in a way that is very similar to cystic fibrosis, a life threatening disease affecting the lungs and other organs.
Bethesda, MD -- Why are some people prone to severe infections, while others handle them with less difficulty? A new research report appearing online in the FASEB Journal (http://www.fasebj.org) attempts to answer this question by shedding light on the genetic differences that influence our ability to fight off bacterial infections.
Scientists are reporting development of the first fast and reliable scientific method to determine the age and authenticity of priceless silk tapestries and other treasures -- such as Civil War General Phillip Sheridan's famous red-and-white battle flag -- in museums and other collections around the world. A report on their work appears in ACS' journal Analytical Chemistry.
A new University of British Columbia study finds that Black Canadians with darker skin are more likely to report poorer health than Black Canadians with lighter skin. The study also suggests that a mismatched racial identity can negatively affect health.
The study, published online in the current issue of Social Science & Medicine journal, provides the first Canadian evidence of the health effects of "colourism," discrimination targeted more strongly at darker-skinned than lighter-skinned people of colour, says the author.
In a literal walk through time along the Ucayali River near Contamana, Peru, a team of researchers found rodent fossils at least 41 million years old – by far the oldest on the South American continent.
The remains – teeth – showed these mouse- and rat-size animals are most closely related to African rodents, confirming the hypothesis that early rodents of South America had origins in Africa, said Darin Croft, an anatomy professor at the Case Western Reserve University School of Medicine and member of the research team.
The prevalence and under-reporting of conflicts of interest by members of guideline panels in the United States and Canada are high, finds a study published in BMJ today. The study exposes the problem of incomplete disclosure and highlights the important relationship between sponsorship of guidelines and presence of conflict of interest.
The prevalence of conflict of interest (COI) between clinicians and industry has been a topic of concern for the medical profession for more than two decades.
Researchers at Mount Sinai School of Medicine have found that conflicts of interest (COI) are prevalent and potentially underreported among individuals participating in the development of clinical practice guidelines, which inform standards of patient care. The findings provide further evidence of the potential influence of industry on medical practice recommendations. The study is published online Oct. 12 in BMJ: The British Medical Journal.
Hospital associated infections (HAI) are often in the headlines, but what is the burden of mortality, morbidity and costs due to HAIs? In this week's PLoS Medicine, Marlieke de Kraker, Peter Davey and Hajo Grundmann, on behalf of the BURDEN (Burden of resistance and disease in European nations) study group, report the results of a prospective clinical investigation into the societal burden of HAIs from 31 European countries.
In this week's PLoS Medicine, James C. Engert of McGill University, Montreal, Canada, and Sonia S. Anand, of McMaster University, Hamilton, Canada and colleagues, on behalf of the INTERHEART investigators, show that the genetic risk for cardiovascular disease conferred by several single nucleotide polymorphisms in the Chromosome 9p21 region may be decreased in individuals who consume a diet high in raw fruits and vegetables.
Rewrite the textbooks and revisit old experiments, because there's a new cog in our cellular machinery that has been discovered by researchers from the University of Alberta and the University of Cambridge Institute for Medical Research.
Hamilton, ON -- A long-held mantra suggests that you can't change your family, the genes they pass on, or the effect of these genes. Now, an international team of scientists, led by researchers at McMaster and McGill universities, is attacking that belief.
The researchers discovered the gene that is the strongest marker for heart disease can actually be modified by generous amounts of fruit and raw vegetables. The results of their study are published in the current issue of the journal PLoS Medicine.
CHICAGO -- In a trial that included about 35,000 men, those who were randomized to receive daily supplementation with vitamin E had a significantly increased risk of prostate cancer, according to a study in the October 12 issue of JAMA.
CHICAGO -- Use of folic acid supplements by women in Norway in the period 4 weeks before to 8 weeks after conception was associated with a reduced risk of the child having severe language delay at age 3 years, according to a study in the October 12 issue of JAMA.
