    This is the first post in a new series.  Each Friday, students volunteer to submit a podcast summarizing what we did in class.  Thanks to Aurora, Deirdre, and Monica for bravely volunteering to submit the first podcast! This week’s update discusses why cells are small, cancer cells, and the controversy over HeLa cells.

  • Is yoga safe for people with heart failure?

    Updated: 2011-01-30 03:58:24
    Apparently so, according to researchers at the University of California, in San Francisco. And, others agree. First, the details. 12 adults with stable heart failure completed 8 weeks of yoga classes. 3 out of 4 patients were Caucasian. The following outcomes were measured. Safety (cardiac and orthopedic adverse events) Physical function (strength, balance, endurance, flexibility) Psychological function (quality of life, depression scores, mindfulness) And, [...]

  • Cognitive behavioral therapy for ADHD

    Updated: 2011-01-30 03:58:23
    Researchers at Massachusetts General Hospital, in Boston, tested cognitive behavioral therapy in adults who were also treated with drugs but still experiencing significant symptoms. First, the details. 86 symptomatic adults with ADHD being treated with medication were randomly assigned to a treatment group for 12 individual sessions. Cognitive behavioral therapy Relaxation + educational support ADHD symptoms were rated (ADHD rating [...]

  • CBT and the risk for heart disease

    Updated: 2011-01-29 19:58:06
    Psychosocial factors are associated with increased risk of cardiovascular disease morbidity and mortality, but the effects of psychosocial factor treatment on heart disease are uncertain. Researchers at Uppsala University Hospital, in Sweden, studied the effects of cognitive behavioral therapy (CBT) on the recurrence of cardiovascular disease. First, the details. 362 women and men who were discharged from the [...]

  • Black tea, green tea, and the risk of heart disease

    Updated: 2011-01-29 19:58:05
    Researchers at the First Affiliated Hospital of Nanjing Medical University, in China, reviewed the association between tea consumption and the risk of coronary artery disease (narrowing of the small blood vessels that supply blood and oxygen to the heart). First, the details. Data from 18 studies were included in this meta-analysis: 13 studies on black tea and [...]

  • Biomarkers of poor outcomes in preemies

    Updated: 2011-01-28 13:40:51
    Scientists at Cincinnati Children's Hospital Medical Center have identified biomarkers of poor outcomes in preterm infants that may help identify new approaches to prevention. Ardythe Morrow, PhD, a researcher at the Cincinnati Children's Perinatal Institute, has identified a polymorphism � a variant in a particular DNA sequence � in a gene important to the development of the immune system. She observed that this polymorphism raises the risk of bad outcomes in preterm infants, including death; necrotizing enterocolitis, which is the death of intestinal tissue; and gram negative sepsis, an overwhelming infection........

  • Impact of Trauma on patients taking warfarin

    Updated: 2011-01-18 13:48:18
    Warfarin use appears to be linked to a significant increase in the risk of death after traumatic injuries, as per a report posted online today that will appear in the May print issue of Archives of Surgery, one of the JAMA/Archives journals. "The prevalence of warfarin use in the United States is unknown, but the Food and Drug Administration estimates that more than 31 million prescriptions for warfarin were written in 2004," as per background information in the article. "Warfarin is a usually used anticoagulant [prevents the formation of blood clots] for the long-term management and prevention of thromboembolic (blood clot formed in one vessel carried by the blood stream to occlude another vessel) events linked to atrial fibrillation (abnormal heart rhythm), mechanical heart valves, deep venous thrombosis (clot formed in a vein deep in the body), pulmonary embolism (clot that causes blockage of a blood vessel in the lung), the antiphospholipid syndrome (condition that increases the risk of blood clot formation) and occasionally, myocardial infarction (heart attack)." ........

  • New Tool for Cell Research

    Updated: 2011-01-17 11:00:06
    Advancements in understanding rotational motion in living cells may help scientists shed light on the causes of deadly diseases, such as Alzheimer's, as per Ning Fang, an associate scientist at the U.S. Department of Energy's Ames Laboratory and faculty member at Iowa State University. In an article entitled "Resolving Rotational Motions of Nano-objects in Engineered Environments and Live Cells with Gold Nanorods and Differential Interference Contrast Microscopy" reported in the November 2 issue of the Journal of the American Chemical Society, and an article in press in ACS Nano, Fang and his research team write about the influence of differential interference contrast Microscopy on revealing nanoparticle movement in living cells........

  • Blood pressure control system found in nephron

    Updated: 2011-01-17 02:59:37
    The kidney is made up of roughly 1 million working units called nephrons. These basic structural units remove waste products from the blood, recycle some substances to be reused and eliminate what is left as urine. The end segment of nephrons, called the distal nephron, helps set blood pressure by controlling the amount of sodium in our blood........

  • Geography plays key role in colon cancer screening

    Updated: 2011-01-11 02:28:03
    New research from UC Davis Cancer Center has observed that whether a person gets screened for colon cancer often depends on where they live in addition to their race or ethnicity. It has long been known that racial minorities have lower colorectal screening rates than whites, presumably because of differences in socioeconomic status, access to care and cultural issues. What hasn't been known, until now, is whether these differences also vary across geographic regions........

  • Thinking about weight loss surgery?

    Updated: 2011-01-07 05:10:07
    gastric band can be helpful in reducing the amount of food someone eats, thereby contributing significantly to weight loss. The procedure is normally carried out using keyhole surgery, with a band (or belt) being placed around the top portion of your stomach. This means you feel “full” after eating only a small portion of food. .......
