Bone marrow stem cells attracted to the site of a cancerous growth frequently take on the outward appearance of the malignant cells around them, University of Florida researchers report in a paper to be published in the August issue of Stem Cells.
New evidence indicates that small pieces of noncoding genetic material known as microRNAs (miRNAs) might influence cancer susceptibility. Differences in certain miRNAs may predispose some individuals to develop cancer, say researchers collaborating in a joint study at the Kimmel Cancer Center at Jefferson in Philadelphia, Ohio State University Medical Center in Columbus and Roswell Park Cancer Institute in Buffalo.
Two genes important for human development and implicated in cancer and schizophrenia also help keep a healthy balance between excitation and inhibition of brain cells, researchers say.
Conducted by the Woolcock Institute of Medical Research, the research found that vacuum cleaning was an ineffective allergy avoidance measure because it removed dust mite allergen from carpets in an inconsistent and incomplete manner.
Asthmatx, Inc., a medical device company that has developed a catheter-based procedure for the treatment of asthma, announced today that positive results from the Research in Severe Asthma (RISA) Trial were reported today at the annual scientific assembly of the American Thoracic Society (ATS) by Neil Thomson, MD, Professor of Respiratory Medicine, University of Glasgow, Glasgow, Scotland.
Could the food we eat be contributing to the continuing rise of antibiotic-resistant infections? Harmless and even beneficial bacteria that exist in our food supply may also be carrying genes that code for antibiotic resistance. Once in our bodies, could they transmit the resistance genes to disease-causing bacteria?
The British Medical Association in Northern Ireland has welcomed the early debate by the NI Assembly on junior doctors’ training.
Researchers from the University of Pennsylvania School of Medicine found in a database study of women heart patients that COX inhibitors such as traditional nonsteroidal anti-inflammatory drugs (NSAIDs) may undermine any purported protection against heart disease in participants taking estrogen therapy. The results were described this week in PLoS Medicine.
Richard Idro, M.M.E.D., of the Kenya Medical Research Institute, Kilifi, Kenya and colleagues conducted a study to determine the incidence and neurological involvement of African children with acute falciparum malaria (a severe type of malaria).
Despite improvements in the ability to diagnose malaria, these diagnostic tests are often underused in Zambia, and patients with negative test results are often prescribed anti-malaria medications, according to a study in the May 23/30 issue of JAMA, a theme issue on malaria.
