A new study by researchers at Montefiore Medical Center reveals that the incidence of anal carcinoma (AC) is increasing among HIV-positive women. The study entitled "High Prevalence of High Grade Anal Intraepithelial Neoplasia in HIV-Infected Women Screened for Anal Cancer" will appear in the Journal of Aids on May 1st, and was conducted from March 2008 to December 2010. Mark H. Einstein, M.D., M.S., Director of Clinical Research, Division of Gynecologic Oncology at Montefiore Medical Center and Professor at Albert Einstein College of Medicine, explained: "Anal cancer was widely associated with HIV-Infected men who have sex with men. But now, this study reveals anal precancerous disease in a high proportion of women with HIV ." The researchers examined 715 asymptomatic HIV-Infected women and found that 10.
A study in the April issue of Archives of Surgery, demonstrates that in comparison with laparoscopic surgery, open surgery seems to be linked to a higher risk of small-bowel obstruction (SBO). The researchers state in their study background that SBO is a common reason for emergency admission. One of SBO's major causes are intraperitoneal or abdominal adhesions, which can develop from peritoneal trauma, for instance before abdominal surgery and develop within days of a surgical procedure. The researchers state: "Laparoscopic surgery is considered to be associated with less surgical trauma, implying a reduction of adhesions", but point out that study literature on the clinical effect of laparoscopy on adhesion-related morbidity has not been convincing. In a population-based register study, which included procedures from January 2002 to December 2004, using the Swedish National Board of Health and Welfare's Inpatient Register, Eva Angenete, M.
New research findings show how it may be possible to render cancer tumours harmless without affecting the other cells and tissues in the body. The findings apply to cancers including breast, lung and bowel cancer. The study was carried out at Lund University in Sweden. Many of the most common chemotherapy drugs used to treat cancer have serious side effects because they not only affect the cells in the cancer tumour, but also the cells in the rest of the body. Researchers at Lund University have now found a connection between two proteins that in different ways control cell division and the possibilities for a cancer tumour to develop. The retinoblastoma protein obstructs cell division and is absent in most types of cancer tumour. The new findings show that its absence leads to an increase in another protein, gamma-tubulin, which, when present in high levels, encourages the development of cancer tumours.
We are surrounded by a constantly changing magnetic field, be it the Earth's or those emanating from devices, such as cell phones. Carlos Martino, an assistant professor at the University of Nevada, Reno, is interested in understanding how these magnetic-field fluctuations change biochemical reactions inside us. Martino explains that the subject is controversial. "Our research shows that exposure to different types of magnetic fields affect biological response, " he says. "More importantly, the exposure levels are well below the standard levels" approved by the World Health Organization. "This raises the concern of safety issues, " he adds. Martino presented some of his work at the Experimental Biology 2012 meeting in San Diego, California. Magnetic fields come in different types. There are static fields, like those around permanent magnets.
Protection Against Many Cancers Provided By Vitamin E In Diet But Not The Form Commonly Used In Supplements
Next time you need to choose between vegetable oil and margarine in that favorite recipe, think about your health and reach for the oil. While the question of whether vitamin E prevents or promotes cancer has been widely debated in scientific journals and in the news media, scientists at the Center for Cancer Prevention Research, at Rutgers Ernest Mario School of Pharmacy, and the Cancer Institute of New Jersey, believe that two forms of vitamin E - gamma and delta-tocopherols - found in soybean, canola and corn oils as well as nuts do prevent colon, lung, breast and prostate cancers. "There are studies suggesting that vitamin E actually increases the risk of cancer and decreases bone density, " says Chung S. Yang, director of the center. "Our message is that the vitamin E form of gamma-tocopherols, the most abundant form of vitamin E in the American diet, and delta-tocopherols, also found in vegetable oils, are beneficial in preventing cancers while the form of vitamin E, alpha- tocopherol, the most commonly used in vitamin E supplements, has no such benefit.
