Study Says Stem Cell ‘Fusion’ Occurs In Tumors May 8, 2006
Oregon Health & Science University research is adding credence to an increasingly popular theory that fusion is what bonds stem cells with bone marrow cells to regenerate organ tissue. Scientists found transplanted cells derived from adult bone marrow fuse with intestinal stem cells of both normal and diseased tissue comprising the cellular lining of intestinal walls. The findings point to bone marrow-derived cells’ role in not only regeneration of damaged tissue, but also disease progression.
Nature Vs Nintendo: Video Games Or National Parks
Are future national park trips for America’s youth likely to be on-line virtual experiences rather than the real thing? A University of Illinois at Chicago ecologist says there may be cause for concern.
White Blood Cells From Cancer-resistant Mice Cure Cancers In Ordinary Mice
White blood cells from a strain of cancer-resistant mice cured advanced cancers in ordinary laboratory mice, researchers at Wake Forest University School of Medicine reported today.
Study Identifies Substances In Grapefruit Juice That Interact Dangerously With Some Drugs
New research from the University of North Carolina at Chapel Hill has identified and established the substance in grapefruit juice that causes potentially dangerous interactions with certain medications.
Venus Express Has Reached Final Orbit
Less than one month after insertion into orbit, and after sixteen loops around the planet Venus, ESA’s Venus Express spacecraft has reached its final operational orbit.
Women With Lung Cancer Have Better Lung Function Than Men
New research in the journal Chest shows that many women recently diagnosed with lung cancer have normal lung function and perform better on lung function tests compared with their male counterparts.
NYU Algorithm Enhances Ability To Detect Cancer Genes
Researchers at New York University’s Courant Institute of Mathematical Sciences have developed a new algorithm that enhances the ability to detect a cancer gene, and have applied their algorithm to map the set of tumor-suppressor genes involved in lung cancer. The algorithm uses data from Affymetrix’s gene-chips that can scan hundreds of patients’ genomes to find gains and losses in gene-copies. The findings will appear in the July issue of the American Journal of Human Genetics.
Copying Nature Could Save Us Energy, Study Shows
New technologies that mimic the way insects, plants and animals overcome engineering problems could help reduce our dependence on energy, according to new research published in the Royal Society journal Interface.
Newly Discovered Dendritic Cells Generate Crucial Cells Of The Immune System
A new type of cell that generates crucial cells of the immune system has been discovered at The Walter and Eliza Hall Institute. With this new knowledge, medical researchers can begin to consider the development of
customized immune therapies using this new cell to target specific infections such as HIV, malaria and influenza; certain cancers; and even autoimmune diseases.
Long-term Estrogen Therapy Linked To Breast Cancer Risk
Long-term estrogen therapy may be related to a higher risk of breast cancer among postmenopausal women who have had a hysterectomy, according to an article in the May 8 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.
