Researchers Find Cancer Cell Weakness, A Breakthrough In The Battle Against Leukemia
3/15/2013
Scientists at Griffith University's Institute for Glycomics and The Saban Research Institute of Children's Hospital Los Angeles have discovered a critical weakness in leukaemic cells, which may pave the way to new treatments. The research team has demonstrated that leukaemic cells can be eradicated by removing a carbohydrate modification displayed on the cell's surface...
A seemingly obscure gene in the female fruit fly that is only active in cells that will become eggs has led researchers at the Stowers Institute for Medical Research to the discovery of a atypical protein that lures, traps, and inactivates the powerful Polo kinase, widely considered the master regulator of cell division...
Blocking Immune Response May Enhance Viral Therapy Against Solid Tumors
3/15/2013
Following several years of study, investigators have found more evidence that viral therapy to treat solid tumors can be enhanced by blocking the body's natural immune response. Oncolytic viruses have shown promise as anticancer agents, with variations of the herpes simplex virus (HSV) among the most commonly used...
Hyper And Micro-Gravity Affect Processes Involved In Reproduction, Brain Diseases And Cancer
3/15/2013
University of Montreal researchers found that changes in gravity affect the reproductive process in plants. Gravity modulates traffic on the intracellular "highways" that ensure the growth and functionality of the male reproductive organ in plants, the pollen tube. "Just like during human reproduction, the sperm cells in plants are delivered to the egg by a cylindrical tool...
Early Identification Of Disease Via New MRI Fingerprint Method
3/15/2013
A new method of magnetic resonance imaging (MRI) could routinely spot specific cancers, multiple sclerosis, heart disease and other maladies early, when they're most treatable, researchers at Case Western Reserve University and University Hospitals (UH) Case Medical Center suggest in the journal Nature...
Rate Of Brain Hemorrhage In Stroke Patients Given TPA Isn't Meaningfully Higher
3/15/2013
Millions of Americans take aspirin or other drugs every day to reduce their risk of heart attacks or other problems caused by blood clots. But when one of them suffers a stroke caused by a clot in their brain, some emergency teams might hesitate to give a powerful clot-busting medication called tPA -- for fear that the combination of drugs might cause dangerous brain bleeding...
Night Shifts May Be Linked To Increased Ovarian Cancer Risk
3/15/2013
Some evidence that risk may be lower for "owls" than "larks" Working night shifts might increase the risk of developing ovarian cancer, indicates research published in Occupational and Environmental Medicine. The risk may be lower for night types ("owls") than for morning types ("larks"), the findings suggest (see accompanying commentary)...
Genital Warts In Young Girls Reduced By Early HPV Vaccination
3/15/2013
The incidence of genital warts, or condylomata, declined by 93 per cent in girls given the HPV vaccine before the age of 14, according to a Swedish national registry study. The study was carried out by researchers at Karolinska Institutet in Sweden, and published in Journal of the National Cancer Institute...
No Clear Evidence That Decline In HRT Use Linked To Fall In Breast Cancer
3/15/2013
Time trends and stats neither support nor refute this claim, say researchers There is no clear evidence that the decline in the use of hormone replacement therapy (HRT) is linked to a reported fall in the numbers of new cases of breast cancer, as has been claimed, suggests a study in the Journal of Family Planning and Reproductive Health Care...
Radiation Raises Breast Cancer Survivors' Risk Of Heart Disease Slightly
3/14/2013
Breast cancer patients who undergo radiation therapy have a slightly increased risk of ischemic heart disease within five years, and the risk persists for at least twenty years, researchers from Oxford University, England, the Karolinska Institute, Sweden, and Copenhagen University Hospital, Denmark, reported in NEJM (New England Journal of Medicine)...
