A revolutionary discovery regarding motile cancer cells made by research scientists at VTT Technical Research Centre of Finland and the University of Turku is challenging previous conceptions. The results have been published on July 25, 2011 in the Journal of Cell Biology, one of the most renowned journals in the field.
Finnish researchers found a new mechanism inhibiting the spread and growth of cancer found in motile cells
In a summer with unprecedented weather events, from tornados, floods, fires and hurricanes, researchers at the University of Pennsylvania School of Nursing found that physiological changes associated with aging and the presence of chronic illness make older adults more susceptible to illness or injury, even death, during a disaster.
Research led by St. Jude Children's Research Hospital scientists advances a strategy for taming the side effects and enhancing the therapeutic benefits of steroids and other medications that work by disrupting the activity of certain hormones.
The approach relies on a small molecule developed at St. Jude. In this study, scientists showed that a compound known as SJ-AK selectively blocked the activity of genes in a cell signaling pathway regulated by thyroid hormone.
PITTSBURGH, Oct. 20 – Exceptional cognitive and physical function in old age leaves a tell-tale immunologic fingerprint, say researchers at the University of Pittsburgh and Children's Hospital of Pittsburgh of UPMC. Likewise, older adults who have mild impairments bear a distinct immunologic pattern, too, according to findings published today in the Public Library of Science: One.
(New York City, October 20, 2011) In the October 20th edition of the journal Cell Host and Microbe, Drs. Claudia Plottel and Martin J. Blaser of the Departments of Medicine and Microbiology at NYU Langone Medical Center, and the Department of Biology at New York University, present a model for understanding how cancer evolves in humans based on an understanding of the bacteria living in our body, the microbiome.
Professor Qin Wenbin from BaoTou Medical College first identified the hemoglobin (Hb) A2 phenomenon 30 years ago. His first paper on this phenomenon was published in Acta Biochimica et Biophysica Sinica, in Chinese, in 1981. Subsequent research investigating its mechanism was published in Chinese in the Chinese Biochemical Journal and Progress in Biochemistry and Biophysics in 1991 and more recently in Electrophoresis, in 2010.
MARSABIT, KENYA (21 October 2011) – In the midst of a drought-induced food crisis affecting millions in the Horn of Africa, an innovative insurance program for poor livestock keepers is making its first payouts today, providing compensation for some 650 insured herders in northern Kenya's vast Marsabit District who have lost up to a third of their animals.
Vancouver − Health prevention strategies to help Canadians achieve their optimal health potential could add a decade or more of healthy years to the average lifespan and save the economy billions of dollars as a result of reduced cardiovascular disease, says noted cardiologist Dr. Clyde Yancy.
Post-menopausal women with high levels of hormones such as estrogen or testosterone are known to have a higher risk of breast cancer. New research published in BioMed Central's open access journal Breast Cancer Research looked at eight different sex and growth hormones and found that the risk of breast cancer increased with the number of elevated hormones - each additional elevated hormone level increased risk by 16%.
The condition tuberous sclerosis, due to mutation in one of two tumor suppressor genes, TSC1 or TSC2, causes the growth of non-malignant tumors throughout the body and skin. These tumors can be unsightly and cause serious damage to organs. Growth of tumors in the brain may cause seizures and in the kidney, liver or heart, tumors can disrupt normal function, to the extent of causing the organ to fail.
There is no link between long-term use of mobile phones and tumours of the brain or central nervous system, finds new research published on bmj.com today.
In what is described as the largest study on the subject to date, Danish researchers found no evidence that the risk of brain tumours was raised among 358,403 mobile phone subscribers over an 18-year period.
Reasoning used in many highly cited cancer publications to support the relevance of animal and test tube experiments to human cancer is questionable, according to a study by researchers from Université Libre de Bruxelles published in the open-access journal PLoS Computational Biology on October 20th 2011.
A team of international researchers has discovered a new Ebola-like virus – Lloviu virus -- in bats from northern Spain. Lloviu virus is the first known filovirus native to Europe, they report in a study published in the journal PLOS Pathogens on Octobr 20th.
