Ginger helps reduce nausea from chemotherapy
Ginger helped prevent or reduce chemotherapy-induced nausea when taken with traditional anti-nausea drugs by patients with cancer, researchers have found. The results are from a randomized, double-blind, placebo-controlled clinical trial, the largest study to examine the potential effects of ginger on chemotherapy-related nausea.
Sentinel lymph node biopsy suitable for staging penile carcinoma
A new study led by the Netherlands Cancer Institute (NKI) and published online May 4 in the Journal of Clinical Oncology confirms that sentinel lymph node biopsy (SLNB) is a valid staging option for men with early stage penile cancer. more
Three genes help breast cancer invade the brain
Breast cancer can appear in the brain years after a tumor in the breast has been removed. This, researchers say, suggests that breast cancer cells must acquire special abilities in order to metastasize to the brain, possibly through the activation of certain genes. Three genes involved in this process in mice have now been identified by Dr. Joan Massagué of Memorial Sloan-Kettering Cancer Center (MSKCC) and his colleagues, according to a study published online in Nature on May 6. more
DEAR1 gene may help drive early-onset breast cancer
In a new study led by researchers at the University of Texas M.D. Anderson Cancer Center, a gene has been identified that regulates the development of the cells that form milk-secreting glands in the breast. The gene, called DEAR1, is mutated or not expressed in many cases of early-onset breast cancer, and it may also serve as a biomarker for identifying patients at high risk of local recurrence. more
Formaldehyde may cause some blood cancers, but risk drops over time
Follow-up data from an ongoing study of U.S. industrial plant workers exposed to formaldehyde support previous findings of a possible link between formaldehyde exposure and risk of death from cancers of the blood and lymphatic system. The latest report by NCI researchers, which appeared online May 12 in the Journal of the National Cancer Institute, includes data through 2004, extending the previous observation period by 10 years.
Opposites attract -- how genetics influences humans to choose their mates
New light has been thrown on how humans choose their partners, a scientist will tell the annual conference of the European Society of Human Genetics today (Monday May 25). Professor Maria da Graça Bicalho, head of the Immunogenetics and Histocompatibility Laboratory at the University of Parana, Brazil, says that her research had shown that people with diverse major histocompatibility complexes (MHCs) were more likely to choose each other as mates than those whose MHCs were similar, and that this was likely to be an evolutionary strategy to ensure healthy reproduction. more
An advance in solving the mysterious machine-workers' disease
Scientists in Ohio are reporting a long-awaited advance toward making the workplace safer for more than one million machinists in the United States who may be exposed to disease-causing bacteria in contaminated metalworking fluids. Those fluids become airborne during machining of metal parts. The study appears in the current edition of ACS' monthly Journal of Proteome Research. more
