Healthcare providers must carefully consider the unique risk factors related to severe obesity in patients undergoing all types of surgery, according to an American Heart Association scientific advisory published in Circulation: Journal of the American Heart Association.
Heart problems in particular are often underestimated during a physical examination in the severely obese patient, according to the advisory.
The skin disease psoriasis is associated with atherosclerosis (a buildup of plaque in the arteries) characterized by an increased prevalence of ischemic heart disease, cerebrovascular disease, peripheral artery disease and an increased risk of death, according to a report in the June issue of Archives of Dermatology, one of the JAMA/Archives journals.
Topical application of the chemotherapy medication fluorouracil appears to reduce potentially precancerous skin patches and improve the appearance of sun-damaged skin, according to a report in the June issue of Archives of Dermatology, one of the JAMA/Archives journals.
Surgical gloves that develop holes or leaks during a procedure appear to increase the risk of infection at the surgical site among patients who are not given antibiotics beforehand, according to a report in the June issue of Archives of Surgery, one of the JAMA/Archives journals.
Rhinosinusitis (infection and inflammation in the sinus passages surrounding the nose) appears to be a primary factor in about one-fifth of toxic shock syndrome cases in children, according to a report in the June issue of Archives of Otolaryngology–Head & Neck Surgery, one of the JAMA/Archives journals.
Adding an antiviral agent to corticosteroids for treatment of Bell's palsy (a condition characterized by partial facial paralysis) is not associated with improved recovery of facial movement function, according to a meta-analysis of previously published studies in the June issue of Archives of Otolaryngology–Head & Neck Surgery, one of the JAMA/Archives journals.
Scientists from A*STAR's Institute of Materials Research andEngineering (IMRE), led by Professor Christian Joachim1, have scored abreakthrough in nanotechnology by becoming the first in the world to invent amolecular gear of the size of 1.2nm whose rotation can be deliberatelycontrolled. This achievement marks a radical shift in the scientific progress ofmolecular machines and is published on 15 June 20092 in Nature Materials3 ,one of the most prestigious journals in materials science.
WEST LAFAYETTE, Ind. - There may be thousands of things large and small that can be done to better control pollution on even the smallest waterways, and a new tool developed at Purdue University may help sort out how to choose the best ones.
SAN FRANCISCO (June 15, 2009) - It's two inches long, grows on wood, and is shaped like a phallus. A new species of stinkhorn mushroom, Phallus drewesii, has been discovered on the African island of Sao Tome and graces the upcoming cover of the journal Mycologia. The mushroom is named after Robert Drewes, Curator of Herpetology at the California Academy of Sciences, and is described in the July/August issue by Professor Dennis Desjardin and Brian Perry of San Francisco State University.
RICHLAND, Wash. -- DNA might be the blueprint for living things, but proteins are the builders. Researchers trying to understand how and which proteins work together have developed a new crosslinking tool that is small and unobtrusive enough to use in live cells. Using the new tool, the scientists have discovered new details about a well-studied complex of proteins known as RNA polymerase. The results suggest the method might uncover collaborations between proteins that are too brief for other techniques to pinpoint.
The vast majority of cancer deaths are due to metastasis, the spread of cancer cells from its primary site to other parts of the body. These metastatic cells tend to move more than their non-metastatic variants but this movement is poorly understood. Scientists are studying cancer cells intently with the hope they can learn to control the movements of the dangerous cells.
TORONTO—A new study shows that an alpha-particle emitting radiopeptide—radioactive material bound to a synthetic peptide, a component of protein—is effective for treating prostate cancer in mice, according to researchers at SNM's 56th Annual Meeting in Toronto. The results could eventually result in a significant breakthrough in prostate cancer treatment, especially for patients whose cancer recurs after the prostate is removed.
Montreal, June 15, 2009 – Recent epidemiological studies have revealed an increase in the frequency of genital malformations in male newborns (e.g., un-descended testes) and a decrease in male fertility.
The role played by the growing presence in our environment of contaminants that reduce male hormone action could explain this phenomenon.
CHICAGO—Possessing a greater purpose in life is associated with lower mortality rates among older adults according to a new study by researchers at Rush University Medical Center. The study, published in the June 15 issue of the journal, Psychosomatic Medicine, is available online at www.psychosomaticmedicine.org.
The Dietary Guidelines for Americans (DGA) provide guidance to promote health and reduce risk of chronic diseases. However, what evidence is there that following the DGA optimizes health? Is this advice useful for individuals already in poor health? To study these questions, researchers at the USDA Human Nutrition Research Center on Aging at Tufts University and Wake Forest University devised a statistical model that assessed adherence to the DGA and then related it to progression of atherosclerosis in women.
