...e, a collection of five indicators, as a marker to differentiate women who were at a higher risk for subsequent cardiovascular disease." In this study, Dr. Nicklas and her colleagues examined 58 obese, postmenopausal women, one-half of whom had metabolic syndrome, to determine whether four factors: aerobic fitnes...Circumcised newborns respond best to anesthetic relief
...ition of pain, and in general, the reports did not differentiate between the painful versus the distressing/stressful aspects of the circumcision procedure," she says. However, that should not deter doctors from using anesthetics, she says. "The results of this review show that dorsal penile nerve block and ring b...Promise of stem cells amplified
...ted the cells with a mix of nutrients to help them differentiate into neurons. They used a tiny electrode designed to measure the electrical activity of individual neurons. This technique, called patch-clamp electrophysiology, revealed that the cells indeed fired action potentials, a neuron's electrical signature...Longterm immune memory cells cells do not develop during chronic viral infections
... the virus with antigen is eliminated, these cells differentiate into memory T cells. A recent study of HIV infect... infection seems to be necessary if T cells are to differentiate into long-term antigen-independent memory T cells," Dr. Ahmed says. "Therapeutic vaccine approaches...MRI technique for measuring blood volume helps distinguish between abscesses and tumors in the brain
...eptibility contrast (DSC) MRI allows physicians to differentiate between cerebral abscesses--inflamed areas in the brain caused by infection--and malignant brain tumors without surgery, says a new preliminary study by researchers from Duke University Medical Center in Durham, NC. For the study, the researchers ana...Initiative yields effective methods for anthrax detection; RAMP and MIDI, Inc., methods approved
...and of related strains to determine its ability to differentiate among them. The 11 laboratories involved in the study reported an acceptable overall sensitivity for B. anthracis identification of 96.3 percent....Skeletal muscle cells could be source of stem cells for regenerating nerve tissue

Arm-muscle cells were obtained from 12 patients undergoing coronary arter...Study may lead to new means of increasing effectiveness of existing cancer treatments
... When activated the Wnt pathway tells cells not to differentiate allowing them to grow unchecked, which can lead to development of a cancer. Drs. Anna Bafico, Stuart Aaronson and colleagues at Mount Sinai School of Medicine discovered that in some breast, ovarian and colon cancer cells this pathway becomes active ...Transplanted bone marrow cells reduce liver fibrosis in mice
...ious reports have shown that bone marrow cells can differentiate into a number of other types of cells, including liver cells, which could help patients with liver cirrhosis and chronic liver failure. To study this possibility, researchers, led by Isao Sakaida, M.D. of Japan's Yamaguchi University, studied the eff...Baby talk: Infants have much to say if adults will only listen
...stimuli, researchers are able to evaluate how they differentiate and respond to sounds and learn language. Much of the response is based on when or how long the child looks at a particular object. The testing appears simple; a parent and child sit in a small, darkened room facing a large-screen television set. Hi...Stem cells given in minimally invasive procedure improve heart function
...ully understand how these cells work, whether they differentiate to become heart muscle cells or cells that promote vessel growth, or whether they serve as homing signals to other cells and substances that help with repair," explained Dr. Patel. The study took place at centers in South America. The research team ......," says Zhang. "Otherwise, it just won't work." To differentiate into a functional spinal motor neuron, the stem ce...onstrates that human stem cells do not necessarily differentiate in linear fashion, as scientists always believed.
