Selenium is a trace element crucial to life - too little or too much of it is fatal. In the July 17 issue of the journal Science, researchers at Yale University and University of Illinois at Chicago detail the molecular mechanisms that govern its metabolism in the human body.
CHICAGO -- Patients who have a heart defect known as patent foramen ovale incidentally discovered and repaired during surgery for a different condition may have an increased odds of postoperative stroke, along with no clear benefit on short-term outcomes or long-term survival, according to a study in the July 15 issue of JAMA.
CHICAGO -- The brain tumor afflicting Sen. Edward Kennedy -- a glioblastoma -- is the most aggressive and wily form of brain cancer. It has foiled researchers' decades-long efforts to thwart its explosive growth in the brain. The lethal tumor ? the most common brain tumor in humans -- nimbly alters its genes like a quick-change artist to elude treatments to destroy it.
CHICAGO (July 14, 2009) -- New research published in the July issue of the Journal of the American College of Surgeons reveals that African Americans with gastrointestinal stromal tumors (GIST), a rare cancer that begins in the wall of the gastrointestinal tract, now have survival rates equivalent to those of Caucasians.
CHICAGO (July 14, 2009) -- Results of a survey published in the July issue of the Journal of the American College of Surgeons show that a large subset of surgical residents consider duty hour regulations (DHR) a significant barrier to their surgical education and express a desire for flexibility to work longer hours than current restrictions allow.
CHICAGO -- The tiny translucent egg nestled in the special laboratory gel was a mere 30 days old, but its four-week birthday caused researchers to quietly celebrate. This was the first time anyone had successfully grown a woman's immature egg cells, contained in a tiny sac called a follicle, to a healthy and nearly mature egg in the laboratory.
MAYWOOD -- Adverse work conditions may be to blame for the decline in the number of primary care physicians nationwide, according to a study published in the latest issue of the Annals of Internal Medicine.
CHICAGO --- John Csernansky wants to take your measurements. Not the circumference of your chest, waist and hips. No, this doctor wants to stretch a tape measure around your hippocampus, thalamus and prefrontal cortex.
Where the first Americans came from, when they arrived and how they got here is as lively a debate as ever, only most of the research to date has focused on dry land excavations. But, last summer's pivotal underwater exploration in the Gulf of Mexico led by Mercyhurst College archaeologist Dr.
Chemists at the California Institute of Technology (Caltech) and the Scripps Research Institute have developed an innovative technique to create cheap but highly stable chemicals that have the potential to take the place of the antibodies used in many standard medical diagnostic tests.
U.S. municipal governments are showing leadership by voluntarily accounting for and reducing greenhouse gas emissions resulting from their operations. They also recognize the huge potential to influence long-term reductions from the residents and businesses in their communities, according to a new report.
CHICAGO -- The American Dietetic Association has released an updated position paper on vegetarian diets that concludes such diets, if well-planned, are healthful and nutritious for adults, infants, children and adolescents and can help prevent and treat chronic diseases including heart disease, cancer, obesity and diabetes.
MAYWOOD, Il. -- If a lump is found in the breast of an adolescent girl, she often will undergo an excisional biopsy.
However, breast cancer is rare in adolescents, and the vast majority of teenage breast lumps turn out to be benign masses that are related to hormones.
Water forms droplets because attractive interactions between molecules produce surface tension. If macroscopic objects -- say, grains of sand -- replace the molecules, the relative strength of this attraction would dramatically drop. What vestiges of liquid behavior remain in such ultra-low surface tension limit?
NEW YORK (June 22, 2009) -- New research shows that physicians failed to report clinically significant abnormal test results to patients -- or to document that they had informed them -- in one out of every 14 cases of abnormal results. In some medical groups, the failure rate is close to zero; in others it is as high as one in four abnormal results.
