Golden Membranes Pave The Way For A Better Understanding Of Cancer And The Immune System
11/02/2011
Football has often been called "a game of inches," but biology is a game of nanometers, where spatial differences of only a few nanometers can determine the fate of a cell - whether it lives or dies, remains normal or turns cancerous. Scientists with the U.S...
Misshapen Red Blood Cells Detected Using Math And Light
11/02/2011
Misshapen red blood cells (RBCs) are a sign of serious illnesses, such as malaria and sickle cell anemia. Until recently, the only way to assess whether a person's RBCs were the correct shape was to look at them individually under a microscope - a time-consuming process for pathologists...
Regulatory T-Cell Clue May Help Prevent Graft-Versus-Host Disease
11/02/2011
Graft-versus-host disease (GVHD) is a serious risk in many kinds of cell transplants, including for stem cell transplants carried out when stem cells are partially depleted of conventional T cells, which play an important role in the immune system. Now, researchers at Moffitt Cancer Center have tested a process by which T regulatory cells (Tregs) can be "expanded" to help prevent GVHD...
Age No Longer Should Be A Barrier To Stem Cell Transplantation For Older Patients With Blood Cancers
11/02/2011
Age alone no longer should be considered a defining factor when determining whether an older patient with blood cancer is a candidate for stem cell transplantation...
Recipients Of Organ Transplants At Increased Risk For Broad Range Of Cancers
11/02/2011
Patients who have received a solid organ transplant, such as kidney, liver, heart or lung, have an overall cancer risk that is double that of the general population, with an increased risk for many different types of malignancies, according to a study in the November 2 issue of JAMA...
Warwick Scientists Uncover Key Element Of Cell Division
11/02/2011
Scientists at Warwick Medical School have uncovered the molecular process of how cells are by-passing the body's inbuilt 'health checkpoint' with cells that carry unequal numbers of chromosomes that have a higher risk of developing cancer. Studying simple yeast cells, scientists now understand the mechanism by which cells ensure their daughter cells receive the correct number of chromosomes...
Low Levels Of Alcohol Consumption Associated With Small Increased Risk Of Breast Cancer
11/02/2011
Consumption of 3 to 6 alcoholic drinks per week is associated with a small increase in the risk of breast cancer, and consumption in both earlier and later adult life is also associated with an increased risk, according to a study in the November 2 issue of JAMA. "In many studies, higher consumption of alcohol has been associated with an increased risk of breast cancer...
Regimen May Improve Cell Transplantation Outcomes For Older Adults With Blood, Bone Marrow Cancers
11/02/2011
Older patients with advanced hematologic malignancies, such as leukemia and lymphoma, who received a conditioning regimen that included minimal-intensity radiation therapy prior to allogeneic (genetically different) hematopoietic cell transplantation (HCT; receipt of bone marrow or stem cells transplant) had survival and progression-free survival outcomes suggesting that this t...
Risk Of Suicide In Men With Prostate Cancer Could Be Lowered By New Findings
11/02/2011
Men with prostate cancer are twice as likely to commit suicide, but a method where they put intrusive thoughts into words may reduce this risk, reveals research at the Sahlgrenska Academy at the University of Gothenburg, Sweden. In a study at the University of Gothenburg's Sahlgrenska Academy, researchers surveyed the thoughts of 833 Swedish men before and after surgery for prostate cancer...
Cigarette smoking appears to impair pancreatic duct cell function -- even for those who quit --putting all smokers at risk of compromised digestive function regardless of age, gender and alcohol intake, according to the results of a study unveiled at the American College of Gastroenterology's (ACG) 76th Annual Scientific meeting in Washington, DC...
