To defeat an enemy, you must first understand it, or so the saying goes. And for nearly every teenager and young adult, acne is a formidable foe, causing damage to their skin and their self-image that can leave long-lasting physical and emotional scars.
But University of Michigan researchers are working to defeat acne by understanding it better on a molecular level, and testing new ideas about how to treat it. They’ve enlisted armies of volunteers in their efforts to explore acne’s
Omega-3 fatty acid may prevent Alzheimer’s disease and slow its progression
UCLA neuroscientists have shown for the first time that a diet high in the omega-3 fatty acid DHA helps protect the brain against the memory loss and cell damage caused by Alzheimer’s disease. The new research suggests that a DHA-rich diet may lower one’s risk of Alzheimer’s disease and may help slow progression of the disorder in its later stages. The journal Neuron reported the findings
Implantable contact lens (ICL) to correct myopia, are safe, effective and have predictable results for correcting moderate to high myopia or nearsightedness. These are the conclusions discussed in an article published in the September issue of Ophthalmology, the clinical journal of the American Academy of Ophthalmology.
The article provided an update to the U.S. Food and Drug Administration’s long-term, follow-up multi-center STAAR Myopic Implantable Contact Lens (ICL) clinical i
Though many issues need to be addressed
A future trends report published today in the American Gastroenterological Association’s journal Gastroenterology, concludes that CT colonography (often referred to as “virtual colonoscopy”) has significant promise. However, the technology is still evolving and the results of CT colonography for screening are variable.
Guidelines of multiple agencies and professional societies underscore the importance of screening for all individ
A lack of correlation between quantitative sonography and dual-energy X-ray absorptiometry (DXA) in detecting osteoporosis makes quantitative sonography impractical for routine diagnostic use, despite it being able to evaluate bone fracture risk without the use of ionizing radiation, say researchers from the University of Vienna in Austria.
Both quantitative sonography and DXA are imaging methods used to measure bone density and quality, with the former using sound waves and the latter X-r
Dental experts have developed a new sedation procedure which could relieve pressure on hospitals and allow patients to avoid potentially risky general anaesthetics. Clinical trials on more than 600 children with extreme dental problems who would usually attend hospital for a general anaesthetic (GA) for dental treatment, found the new procedure was completely successful in 93 per cent of cases.
Researchers at the UK’s University of Newcastle upon Tyne carried out the Government-fun
Though picking up a Salmonella infection abroad could ruin your holiday, reporting it to your doctor could help detect emerging infections in tourist destinations, according to an article published today in BMC Medicine. A comprehensive database containing details of the infections that travellers pick up could help inform countries that have limited surveillance systems about possible disease outbreaks.
In Sweden, all reported cases of Salmonella infection must be entered into th
A tiny capsule containing tissue that secretes a cocktail of brain-nourishing neurotrophic factors may one day help reduce the damage and disability of stroke, according to research published in the September issue of Stroke.
Choroid plexus tissue has innate roles in developing and protecting the brain and when additional tissue is transplanted into an animal model of stroke, it reduces stroke size by about 65 percent, Medical College of Georgia researchers report. “What we have see
Treating heart-attack patients earlier with a more aggressive regimen of cholesterol-lowering medicines may help diminish their chances of sustaining more complications later or dying after their heart attack, researchers at UT Southwestern Medical Center at Dallas have found.
The findings, published online today by The Journal of the American Medical Association, show benefits of treating patients who have recently suffered acute coronary syndromes with higher doses of the choleste
The study of 1,821 patients from Olmsted County, Minn., who had heart attacks between 1982 and 1998 and survived to go home from the hospital, found that nearly half (48 percent) of the deaths within three years of hospital discharge were attributable to not participating in cardiac rehabilitation.
“On average, for patients who participated in cardiac rehab, it was almost as if the heart attack never had happened. They had the same three-year survival as what would be expected fr
For years researchers have tried to determine why the French have such a lower rate of cardiovascular disease, given the amount of fat consumed in their diets. Red wine has been identified as one of the suspects in maintaining a healthy heart, but now a University of Missouri-Columbia researcher has found that alcohol, in moderation, from any source not only maintains a healthy heart, but can reduce the damage to affected tissue following a heart attack.
When a heart attack occurs
A study carried out by the Heart and Lung Centre at Ullevaal Hospital in Oslo has demonstrated that domesticated salmon fed with fish oil containing a large amount of omega-3 fatty acids is better for cardiac patients than salmon fed with vegetable oil (rapeseed oil).
“Cardiac patients who ate domesticated salmon fed with a large amount of omega-3 fatty acids showed reduced risk for further development of the disease,” says professor Harald Arnesen at Ullevaal Hospital. “These pat
Reptiles can make great pets—they’re quiet and they don’t leave fur on the furniture and floors. However, whether wild-caught or store-bought, reptiles often carry salmonella. These bacteria can cause diarrhea, and young children are at particular risk, according to a study in the September 1 issue of Clinical Infectious Diseases, now available online.
Diet, susceptibility, and the lower amount of bacteria needed to infect a child may all contribute to the likelihood of children les
A significant association was found between hypothyroidism and open-angle glaucoma, according to a study appearing in the September issue of Ophthalmology, the clinical journal of the American Academy of Ophthalmology. The relationship between the two has been disputed in prior studies.
Glaucoma, a leading cause of blindness in the United States, is a condition in which the optic nerve is damaged. It can be associated with elevated pressure inside the eye and can lead to vision loss
Bone marrow derived stem cells can give rise to heart muscle cells. This plasticity concept – the ability of bone marrow cell to transdifferentiate into heart muscle cell – is supported by experimental and clinical data. Another possibility is to replace the missing function by causing transdifferentiation of existing cells. Transdifferentiation means converting one sort of cell, e.g. fibroblast, into another, e.g. muscle cell. There is real hope that we may be able to control this unique phenomenon
Myocardial infarction, caused by coronary artery occlusion, can lead up to loss of muscle tissue of the heart and functional detriment, even at times where rapid reperfusion strategies like PTCA or thrombolysis are at hand. In the study presented here, we investigated embryonic endothelial progenitor cells as therapy for ischemia reperfusion injury in a large animal model (pig). This model, which induces an infarct of predictable size in a pig heart, was used to test the cardioprotective potential
