Indulgence in a high-fat diet can not only lead to overweight because of excessive calorie intake, but also can affect the balance of circadian rhythms – everyone's 24-hour biological clock, Hebrew University of Jerusalem researchers have shown. 

The biological clock regulates the expression and/or activity of enzymes and hormones involved in metabolism, and disturbance of the clock can lead to such phenomena as hormone imbalance, obesity, psychological and sleep disorders and cancer. 

Back pain costs more than $100 billion annually in the U.S. but is the surgery to offset it cost effective?  Obviously to people suffering any cost might be worth it but since most people today have health insurance, and the government is likely to institute some form of mandatory health care for those who don't, cost versus actual achieved benefit is an issue. 

Agricultural crop production relies on composted waste materials and byproducts, such as animal manure, municipal solid waste composts, and sewage sludge, as a necessary nutrient source.

Some studies have shown that human hair, which is readily available as waste generated from barbershops and hair salons, combined with additional compost, could be an additional nutrient source for crops. Although human hair has become commercially available to crop producers in the past couple years, it has not been proven to be an exclusive source of nutrients in greenhouse container production.

Contact with nature has long been believed to increase positive feelings, reduce stress and provide distraction from the pain associated with hospital stays and researchers now say they have confirmed the beneficial effects of plants and flowers for patients recovering from abdominal surgery. A recent study by Seong-Hyun Park and Richard H. Mattson, researchers from the Department of Horticulture, Recreation and Forestry at Kansas State University, provides evidence that contact with plants is directly beneficial to a hospital patient's health. Using various medical and psychological measurements, the study set out to evaluate if plants in hospital rooms have therapeutic influences.

Scientists at the Hebrew University of Jerusalem have succeeded in reversing brain birth defects in animal models, using stem cells to replace defective brain cells. 

Neural and behavioral birth defects, such as learning disabilities, are particularly difficult to treat, compared to defects with known cause factors such as Parkinson’s or Alzheimer’s disease, because the prenatal teratogen – the substances that cause the abnormalities -- act diffusely in the fetal brain, resulting in multiple defects. 

University of Cincinnati researchers say they have discovered a new therapy for transplant patients; targeting the antibody-producing plasma cells that can cause organ rejection.  Steve Woodle, MD, and colleagues found that a cancer drug. bortezomib, that is used to treat multiple myeloma, or cancer of the plasma cells, is also effective in treating rejection episodes caused by antibodies that target transplanted kidneys and reversing rejection episodes that did not respond to standard therapies.

B-lymphocytes, or B cells, play a large role in the humoral immune response by making immune proteins that attack transplanted organs.
