Lab Grows Bladder From Patients' Own Cells
Scientists report in an online publication of the Lancet the successful growth of human bladders from live tissue taken from 7 young patients. Until now, only simpler tissue, such as skin, bone, and cartilage, have been grown in the lab. "This suggests that tissue engineering may one day be a solution to the shortage of donor organs in this country for those needing transplants," said Dr. Anthony Atala, the lead researcher of a team of physicians who performed the transplants at Children's Hospital in Boston. Contact-Lens Infection Rising: CDC
The Centers for Disease Control and Prevention are monitoring reports of an increase in a fungal infection involving patients who wear contact lenses. The fungus, called fusarium, is commonly found in plants and soil in tropical and subtropical areas. Without eye-drop treatment the infection can scar the cornea and blind its victims. Researchers are trying to determine what's causing the increase. The only common denominators are that most patients wore contact lenses and lived in a warm climate where the fungus can grow abundantly. Girls More Easily Addicted to Drugs, Alcohol
A new book, "Women Under The Influence," published by the National Center on Addiction and Substance Abuse at Columbia University, finds that girls have a much higher risk of developing addiction to tobacco, alcohol, and drugs than boys of the same age. According to the authors, part of the reason is the physiological make-up of girls' bodies, which contain more fat and less water than boys, allowing them to retain alcohol and other chemicals longer. BBQ Linked with Prostate Cancer: Study
A compound, PhIP, formed when meat is charred at very high temperatures both initiates and promotes the growth of prostate cancer cells in rats, a new study finds. "For humans, the biggest problem is that it's extremely difficult to tell how much PhIP you've ingested, since different amounts are formed depending on cooking conditions," said Dr. Angelo De Marzo who conducted the study at John's Hopkins University in Baltimore. Menopause Trigger Linked to Depression
Two separate studies that measured hormonal levels of women over an extended period found that women's chances of developing depression grew as they aged. One study reported that women with a history of PMS, were more likely to experience depression in menopause. Dr. Lee Cohen of Harvard University Medical School said women and their doctors should not discount a disabling depression during the transition from normal menstrual cycles to the time when a woman's periods cease.
