The editorial, which ties in with a seminar on hypertension, says: “Despite very effective and cost-effective treatments, target blood pressure levels are very rarely reached, even in countries where cost of medication is not an issue. Many patients still believe that hypertension is a disease that can be cured, and ...
Green and colleagues tested whether doctors showed unconscious race bias and whether the scale of such bias predicted recommendations for medical intervention to dissolve clots (thrombolysis) for black and white patients with acute coronary conditions. A total of 220 doctors from four academic medical centres in Atlanta and Boston were ...
The nanoparticle polymer is made of peroxalate esters. A fluorescent dye (pentacene) is then encapsulated into the polymer. When the nano particles bump into hydrogen peroxide, they excite the dye, which then emits photons (or light) that can be detected (Credit: Image courtesy ...
Researchers from Vanderbilt University Medical Center and UCLA tested blood from 1,400 pregnant women in a Danish birth registry and found that babies of women with high perfluorooctanoate (PFOA) levels were 175 grams lighter than those born to mothers in the lowest exposure level. Animal tests ...
“We hypothesized that people living to 100 and beyond must be buffered by genes that interact with disease-causing genes to negate their effects,” says Dr. Aviv Bergman, a professor in the departments of pathology and neuroscience at Einstein and senior author of the study, which appears in the August 31 ...
A study into the frontal cortex, the key region of the brain involved in decision making, has shown that drug users have to place much greater demand on the brain to control impulses. The two year study was conducted by researchers Dr Murat Yücel and Dr Dan Lubman of the ORYGEN ...
Adult obesity rates rose in 31 states last year, according to the fourth annual F as in Fat: How Obesity Policies are Failing in America, 2007 report from the Trust for America’s Health (TFAH). Twenty-two states experienced an increase for the second year in a row; no states decreased. A ...
Prof. Michael Belkin (Credit: Image courtesy of Tel Aviv University) If your child is born in the winter or fall, it will have better long-range eyesight throughout its lifetime and less chance of requiring thick corrective glasses, predicts a Tel Aviv University investigation led by ...
This finding, published in the journal Experimental Eye Research, might be particularly important because zinc supplements are widely given to patients to help boost weak immune systems. In addition, a 2001 study from the National Eye Institute found that high doses of zinc supplements, combined with antioxidants, may postpone the ...
Plaques comprised of amyloid-beta are the hallmark pathology of Alzheimer’s disease. In this study, the scientists used an amyloid-degrading enzyme to clear these amyloid cobwebs from the brain - as illustrated in these treated (below) versus untreated (above) brain images.

The psychological elements of distress and dissatisfaction may account for the traditional view of PE as a psychological condition. It has recently been suggested that PE might be associated with perturbations in serotonergic 5-hydroxytrptamine (5-HT) neurotransmission. This had led to the development of targeted therapies for PE that might alter ...
Now an interdisciplinary team led by researchers from Rensselaer Polytechnic Institute has found a key link that causes malarial infection in both humans and mosquitoes. If this link in the chain of infection can be broken at its source ...
The method is not just a bonus for translational research, but also has made it possible to determine that genes long associated only with cancer are also expressed in chronic wounds. The team of scientists, based at Ohio State University Medical Center, is using laser capture microdissection to pluck blood vessels, ...
Schliekelman used mathematical models to calculate the possible effect of “kin selection” on natural evolution. “Natural selection is typically seen as ‘survival of the fittest’, but in this case it might be more accurate to say ‘survival of the fittest families,’” says Schliekelman. His research led to the following conclusions: ...
The study involved male mice that were fed a plant compound found in red wine called resveratrol, which has shown anti-oxidant and anti-cancer properties. Other sources of resveratrol in the diet include grapes, raspberries, peanuts and blueberries. In the study resveratrol-fed mice showed an 87 percent reduction in their risk of ...
The study examines the factors that led to the adoption of Quebec’s drug policy in 1997 and of the MMA in 2003, finding that both programs were developed in response to popular discontent, pressure from the pharmaceutical industry, and the determination of the government of the day to leave its ...
A study this year found no association between childhood obesity and 100 percent fruit juice with no sugar added. “That’s big news, and it’s made a difference in what I tell my patients,” says Rockwell, D.O., assistant professor in the Department of Family Medicine at the University of Michigan ...
By wearing this small, wireless device being developed by scientists in Rensselaer’s Lighting Research Center, users can monitor their daily rest and activity pattern as well as exposure to circadian light. The tool will have the capacity to communicate with the user in ...
Chun-che Tsai of Kent State (above), along with fellow researchers Jim Jamison of Summa Health System and Tom Miller of IC-MedTech Inc., have developed a new paradigm in drug discovery based on the pharmacologic properties of liquid crystals. (Credit: Image courtesy of Kent ...
The researchers looked at men and women sleeping less than or equal 5 hours a night to see if their risk of having hypertension was any higher than men and women getting the recommended 7 hours or more of sleep a night. Among other problems increased hypertension does increase the ...
The report from CDC’s National Center for Health Statistics (NCHS) is based on approximately 99 percent of death records reported in all 50 states and the District of Columbia for 2005 and documents the latest trends in the leading causes of death and infant mortality. The increase ...
They range from problems such as government corruption to complex questions surrounding community and public engagement, cultural acceptability and gender. The study, conducted by an international team of bioethics experts from the McLaughlin-Rotman Centre for Global Health in Toronto (MRC), was supported by the Grand Challenges in Global Health (GCGH) initiative, ...

Dr Joanna Scurr, in red, with one of the 70 women in her study. The woman has eight sensors placed on her body – on her shoulders, collarbone, nipples and hips. As she runs the sensors reveal her breasts move in a figure ...
The team will also work to enhance the security of the systems used in the process, thereby reducing the possibility of identity theft and cyber-terrorism. The effort is being supported by a $400,000 grant from the National Science Foundation’s Cyber Trust Program. Hu, the principal investigator, will collaborate with Yang ...
Professor David Gunnell of the University’s Department of Social Medicine and colleagues from the South Asian Clinical Toxicology Research Collaboration in Sri Lanka found that Sri Lanka’s import restrictions on the most toxic pesticides were followed by marked reductions in suicide. Between 1950 and 1995 suicide rates in Sri Lanka ...
“Only in recent times have women acquired significant control over their own fertility, and many are preferring not to be saddled with the burden of raising children," says Lonnie Aarssen, a Biology professor who specializes in reproductive ecology. "The question is whether this is just a result of economic factors ...
In research to be presented to the British Sleep Society, Professor Francesco Cappuccio from the University of Warwick’s Warwick Medical School will show the results of a study of how sleep patterns affected the mortality of 10,308 civil servants in the “Whitehall II study.” Amongst other things the data they ...
