RIVERSIDE, Calif. – Typically, tobacco companies market harm-reduction cigarettes as being safer than traditional "full-flavored" brands, leading many smokers to conclude that the use of harm-reduction brands lowers their exposure to toxicants.
But a UC Riverside study now shows that smoke from these "light" or "low-yield" harm-reduction cigarettes retains toxicity and that this toxicity can affect prenatal development.
CHICAGO (December 8, 2008) – New research published in the December issue of the Journal of the American College of Surgeons (JACS) suggests that surgical procedures that are shorter in duration and the use of fewer blood transfusions characterize hospitals that have a lower incidence of surgical site infections (SSI). Furthermore, the study concludes that strategies to reduce the length of operations and the number of blood transfusions should complement basic aseptic techniques in the operating room.
Cells are filled with membrane-bound organelles like the nucleus, mitochondria and endoplasmic reticula. Over the years, scientists have made much progress in understanding the biomolecular details of how these organelles function within cells, but understanding the actual physical forces that maintain the structures of these organelles' membranes continues to be a challenge.
Pregnancy and surgery patients with a serious blood disorder that causes excessive clotting have responded well to treatment with a man-made anti-clotting protein. Results from a study by researchers at Yale School of Medicine and other institutions were presented December 6 at the Annual Meeting of the American Society of Hematology (ASH) in San Francisco.
WEST LAFAYETTE, Ind. - Purdue University scientists found that mice raised in cages may relieve stress with behaviors associated with mice in the wild. And for researchers using lab mice, this may mean that by allowing mice to express these behaviors they can conduct research with animals that act and respond more naturally, hopefully making research data more reliable.
Laboratory mice live in sterile environments controlled by humans. Joseph Garner, assistant professor of animal sciences, said that can be stressful for the animals because they do not have much control.
SAN FRANCISCO - Taking blood stem cells collected from an umbilical cord into the lab and expanding their number before transplanting them to replace a patient's blood supply is as safe as a standard cord blood transplant, researchers reported today at the 50th Annual Meeting of the American Society of Hematology.
Annie knocks Melissa to the floor to get her doll. Alexis screams at the kid who grabbed his toy truck. Every day, in daycares across Quebec, similar scenes are witnessed by early childhood educators who try to foster calm by encouraging kids to express their anger and frustration in more contructive ways.
Childhood sexual abuse victims with a strong religious upbringing often report feeling terrible guilt about their assault, which doesn't surprise Jean-Guy Nadon. A professor of theology and religious sciences at the Université de Montréal, Nadon has conducted dozens of interviews with women who were sexually abused as children and found the impact of religious beliefs can produce varying reactions.
WEST LAFAYETTE, Ind. - Researchers from Purdue and Stony Brook universities have determined the precise atomic-scale structure of the poliovirus attached to key receptor molecules in human host cells and also have taken a vital snapshot of processes leading to infection.
The virus binds to a receptor on the cell to form a single complex.
Having kids believe there's a jolly man in a red suit who visits on Christmas Eve isn't detrimental, although some parents can feel they're outright lying to their children, according to a new analysis by Serge Larivée.
"When they learn the truth, children accept the rules of the game and even go along with their parents in having younger children believe in Santa," says Larivée, a psycho-education professor at the Université de Montréal. "It becomes a rite of passage in that they know they are no longer babies."
A new study by researchers at The Medical College of Wisconsin Cancer Center Milwaukee, has found that African Americans and whites have identical survival rates after undergoing autologous (self donor) bone marrow transplant treatment for a common cancer of the bone marrow (multiple myeloma). However, in a previous study the researchers showed that African Americans were only half as likely as whites to actually receive a bone marrow transplant, the well-established life-prolonging treatment for the disease.
A team of researchers from Penn State University and the University of Chicago has uncovered clues that may explain how and why a particular virus, called N4, injects an unusual substance -- an RNA polymerase protein -- into an E. coli bacterial cell. The results, which are published in the current issue of the journal Molecular Cell, contribute to improved understanding of the infection strategies used by viruses that attack bacterial cells. Such viruses are known as bacteriophages, or phages.

UCB today announced new findings from analyses of pooled Vimpat(r)(lacosamide) clinical trial data, demonstrating that the newantiepileptic drug (AED) starts working during the first week oftreatment and across doses in a challenging patient population, whenadministered as adjunctive therapy. The analyses also showed thatVimpat(r) provides consistent seizure reduction versus placebo, whenadded to concomitant AEDs, and that it is generally well-tolerated.These data were presented at the 62nd annual meeting of the AmericanEpilepsy Society in Seattle.
