A new study has shown that adding boron-nitride nanotubes to the surface of cancer cells can double the effectiveness of Irreversible Electroporation, a minimally invasive treatment for soft tissue tumors in the liver, lung, prostate, head and neck, kidney and pancreas. Although this research is in the very early stages, it could one day lead to better therapies for cancer. The study was carried out by researchers in Italy at the Institute of Life Sciences, Scuola Superiore Sant'Anna in Pisa with BNNTs provided by researchers at NASA's Langley Research Center, the Department of Energy's Thomas Jefferson National Accelerator Facility and the National Institute of Aerospace. Irreversible Electroporation is a new therapy for difficult-to-treat cancers in soft tissues. It is offered in many cancer treatment centers across the United States, and is being studied for effectiveness on a wide variety of specific cancers.
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 team of American researchers have created a portable, miniature microscope in the hope of reducing the time taken to diagnose oral cancer. The probe, which is around 20 cm long and 1 cm wide at its tip, could be used by doctors to diagnose oral cancer in real-time or as a surgical guidance tool; dentists could also use it to screen for early-stage cancer cells. The probe has been presented in IOP Publishing's Journal of Micromechanics and Microengineering, and has shown good agreement with images of oral cancers obtained using conventional, much slower techniques at the University of Texas Health Science Centre at San Antonio, TX. Historically, the death rate associated with oral cancer is particularly high; not because it is hard to discover or diagnose, but due to the cancer being routinely discovered late in its development.
According to a study in the April 25 issue of the Journal of the National Cancer Institute, genotype rs1051730-rs16969968 and objective measures of tobacco exposure are associated with each other. The link indicates that the risk of developing lung cancer is mostly, if not completely, caused by the level of tobacco exposure. Scientists are aware of the link between the rs1051730-rs16969968 genotype and heaviness of smoking, an individual's risk of lung cancer and other smoking-related outcomes. Previous research was generally based on participants' self-reported smoking habits, however, this could have led to underestimating certain links and obscured the contribution of how heavy a person smokes by potentially upsetting the balance between the link to lung cancer and other health outcomes.
Brain scans of a small group of people can predict the actions of entire populations, according to a new study by researchers from the University of Michigan, the University of Oregon and the University of California at Los Angeles. The findings are relevant to political advertising, commercial market research and public health campaigns, and broaden the use of brain imaging from a diagnostic to a predictive tool. As opposed to the wisdom of the crowd, the study suggests that the neurological reactions of a few - reactions that people are not even consciously aware of and that differ from the opinions they express - can predict the responses of many other people to ad campaigns promoting specific behaviors. "Brain responses to ads forecasted the ads' success when other predictors failed, " said Emily Falk, director of the U-M Communication Neuroscience Lab and lead author of the study, which appears online in Psychological Science.
