Dartmouth Medical School cardiology researchers have discovered a new mechanism for what drives the growth of muscle tissue in the lining of injured heart vessels that can eventually lead to blockage. Their study, reported in the October 19 issue of the journal Circulation, raises important questions about the use of drugs that promote or prevent angiogenesis – the formation of blood vessels – to treat the condition.
Normal heart arteries have a muscle tissue layer inside their

To the surprise of many people, the loss of fat and sun exposure play a bigger role than gravity in aging the face, according to a study presented today at the American Society of Plastic Surgeons (ASPS) Plastic Surgery 2004 conference in Philadelphia.
“People make assumptions about how the face ages because when they pull up on their facial skin, they look better,” said Val Lambros, MD, A
Children prenatally exposed to pollutants, such as motor vehicle exhaust, and postnatally exposed to environmental tobacco smoke (ETS) may be more likely to suffer from asthma and related symptoms early in life. A new study in the October issue of CHEST, the peer-reviewed journal of the American College of Chest Physicians, shows that young children who are exposed to these pollutants may be significantly more likely to develop respiratory conditions at ages 12 and 24 months.

A study published in the October issue of the American Journal of Psychiatry by an Italian group of investigators headed by Professor Giovanni A. Fava (University of Bologna) suggests, that with appropriate psychosocial interventions, half of the patients with recurrent depression could be still well and drug free six years after termination of treatment, instead of being linked to long term drug treatment.
A number of controlled trials have suggested that cognitive behavior st
Research in monkeys suggests that the type of progestin in hormone therapy could dramatically affect heart attack severity. The study, by a Wake Forest University Baptist Medical Center researcher and colleagues, was reported today at the annual meeting of the North American Menopause Society in Washington, D.C.
“One type of hormone therapy limited heart muscle damage to only 5 percent while another resulted in permanent damage to 35 percent of muscle,” said J. Koudy Williams, P
As interactions of cellular proteins increasingly take center stage in basic biomedical research, studies are revealing a complex molecular choreography with implications for human health and disease.
In a report currently appearing in the online issue of the journal Nature Cell Biology, scientists at the University of North Carolina at Chapel Hill School of Medicine and the UNC Lineberger Comprehensive Cancer Center describe – for the first time – how some proteins interact to ens
A new study finds support groups can relieve the anxiety and depression associated with carrying BRCA1 or 2 gene mutations, the so-called “cancer genes.” The results of the first study to investigate a support-group model intervention for women at high risk of breast cancer will be published in the November 15, 2004 issue of CANCER, a peer-reviewed journal of the American Cancer Society. A free abstract of this article will be available via the CANCER News Room upon online publication.
The treatment of obesity has proven that it can reduce the onset of lifestyle diseases such as hypertension, high cholesterol levels, diabetes mellitus, and even erectile dysfunction.
And according to the University of Adelaide’s Associate Professor Gary Wittert, who is championing The Florey Adelaide Male Ageing Study, there is a compelling argument for an aggressive intervention program given the high prevalence of obesity and the relationship to the aforementioned health problems
Doctors and other health-care professionals should be more aware of the association between infant crying and potentially abusive parental behaviour, conclude authors of a research letter in this week’s issue of THE LANCET.
Child abuse and neglect are important causes of child illness and death. An estimated 6 young infants per 100,000 die from the effects of child abuse each year; non-fatal infant morbidity could be up to 2000 times greater than this annual death rate. Sijmen A Reij
Researchers from the University of Edinburgh are launching a new two-year study aimed at improving treatment for three of Scotland’s most common life-threatening diseases: heart disease, stroke and diabetes. The study will recruit 1,000 adults from one of the remotest parts of the UK– the North Isles of Orkney. The islands have been chosen for the project because the people living there are isolated geographically, which means they share a more similar environment: there is less variety in
The best approach for repairing breaks in the thin bone that separates the brain from the nasal cavity is through the nasal cavity, according to an analysis of 92 patients who had this increasingly common approach to treating a fortunately rare problem.
The intranasal endoscopic approach is the best way to treat a potentially very bad problem,” says Dr. Stilianos E. Kountakis, vice chair of the Medical College of Georgia Department of Otolaryngology-Head and Neck Surgery and princi
For people who buy clothing on television shopping channels, the hosts of the programs may play a significant role in leading them to make purchases.
A new study found that television shoppers who developed one-sided relationships with hosts of apparel programs were also more likely to buy clothing impulsively from these shows than were other shoppers. “Some viewers regard the hosts of shopping programs almost as being friends, and they develop a pseudo-relationship over time,” said S
Researchers in the Department of Psychology at Carnegie Mellon University have completed a study challenging a popular theory that claims bodily states can guide decision-making when conscious knowledge isn’t available. The paper, written by doctoral student Tiago V. Maia and James L. McClelland, the Walter Van Dyke Bingham Professor of Psychology and Cognitive Neuroscience, will be published online next week in the Proceedings of the National Academy of Sciences.

Rheumatoid arthritis (RA), like many chronic diseases of the immune system, likely results from a combination of genetic susceptibility and environmental triggers. Recently, a team of researchers in Sweden set out to investigate the interaction of two specific risk factors: the presence of a gene encoding protein sequence called the shared epitope (SE), the major genetic risk factor so far defined for RA, and cigarette smoking. The results, published in the October 2004 issue of Arthritis & Rheumati
A review of published medical literature shows that a common sinus surgery can help people suffering from chronic fatigue caused by sinusitis. The results were presented today at the seventh International Conference on Chronic Fatigue in Madison, Wisconsin.
“The entire body of available medical literature points to the same conclusion: functional endoscopic sinus surgery reduces the chronic fatigue of sinusitis,” said Alexander C. Chester, MD, clinical professor of medicine at Geor
Hormone deprivation unnecessary with high-dose radiation, Fox Chase Cancer Center study finds
Men with prostate cancer who do not have a high risk of recurrence or disease progression do not need to have long-term hormone therapy in addition to external-beam radiation therapy if they receive high radiation doses. That is the finding of a Fox Chase Cancer Center study presented today at the 46th Annual Meeting of the American Society for Therapeutic Radiology and Oncology in Atlanta,
