Most abuse of boys done by parents … most frequently mothers
According to a study in the October 18 issue of the Annals of Internal Medicine, a history of childhood physical abuse may be common in men from urban settings, and these men with physical abuse histories may be more likely to commit domestic violence. The study found that the childhood abuse was primarily committed by parents, with mothers being the most frequent abusers.
“The results provide a circumstanti
New studies unveiled at bone marrow failure symposium
The following studies on bone marrow failure diseases will be presented at the Bone Marrow Failure Scientific Symposium Oct. 18-19, L’Enfant Plaza Hotel in Washington, DC. Organized by the Aplastic Anemia & MDS International Foundation, Inc. (AA&MDSIF), the symposium is sponsored by the National Institutes of Health, including the Office of Rare Diseases, the National Heart, Lung and Blood Institute and the National Cancer
Evolutionary Trade-Off Exists Between Advantage and Disadvantage
Some viruses’ ability to exploit the human body’s own defenses to increase their replication may be both a blessing and curse, according to the findings of a study conducted by researchers at the Johns Hopkins Bloomberg School of Public Health. The process is known as antibody-dependent enhancement. Scientists believe antibody-dependent enhancement may allow the dengue virus to grow more rapidly in people who we
Researchers at Fox Chase Cancer Center found no effects of type II diabetes on aggressiveness of prostate cancer but found that long-term survival is worse. The findings were presented today at the 47th Annual Meeting of the American Society for Therapeutic Radiology and Oncology in Denver, Colo.
Previous research suggests that insulin may spur the growth of prostate cancer cells. In type II diabetes, the body fails to properly use insulin, which can lead to an excessive amount of insulin
How we perceive another’s moral character can influence the nature of our economic decisions and the neural mechanisms underlying these choices, according to a new study by researchers at New York and Cornell universities. The findings, which appear in the latest issue of the journal Nature Neuroscience, run counter to the assumptions favored by many economists that individuals behave opportunistically.
The study’s researchers were Mauricio Delgado, a post-doctoral research
New data suggest that a home-based environmental intervention program is a cost-effective way to improve the health of inner-city children who have moderate to severe asthma. The program successfully decreased allergen levels in the home and reduced asthma symptoms. The data also show that the cost would be substantially lower if the interventions were implemented in a community setting, and that they would be as cost-effective as many drug interventions.

Scientists at the University of North Carolina at Chapel Hill School of Medicine have identified an elusive protein that performs a necessary step in the production of human chromosomes.
The new study appears in the most recent issue (Oct. 7) of the journal Cell.
The study found that a protein called CPSF73 acts like scissors to cut strands of histone messenger RNA (mRNA) in the cell nucleus. This cutting action produces the mRNA needed to create histone proteins that com
Ozone is being wrongly blamed for many of the deaths during hot weather spells, finds a new UCL (University College London) study. UCL scientists warn that amidst all the concerns over air pollution, the more basic health message of ‘staying cool when the weather is hot’ may be being forgotten.
The study, published online in the journal Environmental Research, modelled the daily mortality rate of people over 65 (who suffer most of the heat-related deaths) in Greater London from 1991
UCI study shows link between infant stress and later deficits in brain-cell communication for learning and memory function
Psychological stress during infancy has been found to cause early impaired memory and a decline in related cognitive abilities, according to a UC Irvine School of Medicine study. The study suggests that the emotional stress associated with parental loss, abuse or neglect may contribute to the type of memory loss during middle-age years that is normally seen in
Study of otherwise healthy men reveals indications of coronary artery disease
Erectile dysfunction may be a sign that coronary artery disease is developing, even in men without typical risk factors, according to a new study in the Oct. 18, 2005, issue of the Journal of the American College of Cardiology.
“We think that erectile dysfunction represents the ’tip of the iceberg’ of a systemic vascular disorder; thus potentially preceding severe cardiovascular event
Long-term tobacco use associated with dulled thinking and lower IQ, study finds
Smokers often say that smoking a cigarette helps them concentrate and feel more alert. But years of tobacco use may have the opposite effect, dimming the speed and accuracy of a person’s thinking ability and bringing down their IQ, according to a new study led by University of Michigan researchers.
The association between long-term smoking and diminished mental proficiency in 172 alcohol
Looking into our eyes may help doctors predict who is at risk for stroke. A new study found that people with changes in the small blood vessels in their eyes are more likely to later suffer a stroke than people without these signs.
The results held true even after researchers took into account traditional risk factors for stroke such as smoking and high blood pressure, according to the study published in the October 11, 2005 issue of Neurology, the scientific journal of the
A new study concludes that widespread screening for cardiovascular risk by measuring blood levels of C-reactive protein (CRP), a protein produced by the liver, should not be advocated. Researchers at the University of Maryland School of Medicine in Baltimore analyzed data from more than 15,000 adult men and women and found that CRP appears to be tightly linked to traditional risk factors for heart disease rather than being an independent risk factor. The study is published in the October 10, 2005
No good evidence exists that fossilized structures found in China and which some paleontologists claim are the earliest known rudimentary feathers were really feathers at all, a renowned ornithologist says. Instead, the fossilized patterns appear to be bits of decomposed skin and supporting tissues that just happen to resemble feathers to a modest degree.
Led by Dr. Alan Feduccia of the University of North Carolina at Chapel Hill, a team of scientists says that as a result of their
U.S. commercial building owners could save substantially on annual heating and cooling energy costs by improving airtightness of their buildings’ envelope, according to a recent National Institute of Standards and Technology (NIST) study. The research used simulation software to evaluate the energy impact of improved air barriers in three typical non-residential buildings in five cities, each in a different climate zone. The results predicted potential annual heating and cooling energy c
Researchers from the University of California, San Francisco and Georgia Institute of Technology have found a new way to kill cancer cells. Building on their previous work that used gold nanoparticles to detect cancer, they now are heating the particles and using them as agents to destroy malignant cells.
The researchers are a father and son, working together on opposite coasts. Their study findings are reported in the on-line edition of the journal Cancer Letters, found at Sci
