UW launches study testing adult stem cells for heart damage repair

...icine and Public Health is among the first medical centers in the country taking part in a novel clinical trial investigating if a subject's own stem cells can treat a form of severe coronary artery disease. The trial, just underway at UW Hospital and Clinics, is enrolling subjects in the Autologous Cellula...

Vasectomy may put men at risk for type of dementia

...in the frontal lobes; in PPA, it's in the language centers of the left hemisphere of the brain. Weintraub theorizes a vasectomy may raise the risk of PPA (and possibly FTD) because the surgery breeches the protective barrier between the blood and the testes, called the blood-testis barrier. Certain ...

Chemo combination improves survival in asbestos-related cancer

...xamined data from a clinical trial of 20 treatment centers in Europe, the Americas, Australia and Asia. Eighty-one percent of the patients were men, with an average age of 61. Patients who received the combination treatment survived an average 2.8 months longer. Patients receiving both medications also r...

Analysis of rhesus monkey genome uncovers genetic differences with humans, chimps

...a were carried out at each of the three sequencing centers using different and complementary approaches and then combined into a single "melded assembly." In their analysis, scientists from 35 institutions compared this melded assembly to the reference sequence of the human genome, a newer unpublished draft ...

ConocoPhillips establishes $22.5M biofuels research program at Iowa State

...th ties to 18 academic departments and 19 research centers and institutes across campus. Those researchers have attracted more than $57 million in sponsored research funding since 2002. The ConocoPhillips research program will add to that total. "Iowa State University, with its central location in the agr...

Study examines risk of soft tissue sarcomas in hereditary retinoblastoma survivors

...ts were diagnosed between 1914 and 1984 at medical centers in New York and Boston and were followed for an average of 25.2 years. More than half of the patients were younger than 1 year old when diagnosed, and most (88.2 percent) of the patients were treated with radiation. A total of 69 soft tissue sarc...

In obesity, brain becomes 'unaware' of fat

... to control animals. Their brains?appetite control centers also regained sensitivity to leptin. “That was a surprise, a nice surprise,?Cowley said. “We had thought it might be more irreversible than that.? However, Cowley cautioned, previous studies in humans haven’t always supported the idea that reduc...

Mechanism of nicotine's learning effects explored

...he neurons of the prefrontal cortex, which contain centers for learning and memory. Researchers had known that nicotine enhances learning by activating receptors for the neurotransmitter acetylcholine. Such neurotransmitters are the chemical signals that one neuron launches at another to trigger a nerve i...

NIAID expands capability for influenza research and surveillance

Researchers develop way to calculate speed of bacterial sex

...unknown. The study of conjugative gene transfer centers on biofilms, a coat formed by colonizing bacterial cells. "While scientists have studied [conjugation] in the lab, and wondered about its impact in nature, current computer models of conjugation were pretty basic," said Ginn. UC-Davis researche...

Study shows continued success for new HPV vaccine against virus responsible for cervical cancer

...archers at more than a dozen international medical centers evaluated the efficacy of quadrivalent vaccine targeting HPV types 6, 11, 16, 18 in more than 12,000 women ages 15 to 26 in 13 countries for nearly three years. They found a near 100 percent efficacy rate in prevention of HPV types 16 and 18. "...

Traumas like Sept. 11 make brains more reactive to fear

...een found to make the brain's emotional processing centers -- particularly the amygdalae, the parts of the brain that judge emotional intensity and make emotional memories -- more sensitive in cases of PTSD. The findings suggest that events that trigger shock, fear and horror that are within a normal range...

Human stem cell treatment restores motor function in paralyzed rats

...,” said Marsala. “The spinal cord and brain motor centers are still partially connected, but there has been a selective loss of inhibitory neurons in the spinal cord. Since these cells are necessary for coordinated motor activity, our research aims to replace these lost neurons by grafting new spinal stem ...

Gene expression patterns predict rapid decline in idiopathic pulmonary fibrosis patients

...itical for patients with the disease to be seen in centers that are actively involved in IPF research, so we can help them better decide a course of action." These findings also highlight the variability in the progression and outcome of IPF and may explain, in part, the difficulty in obtaining significan...

Extra-aggressive form of idiopathic pulmonary fibrosis identified

...itical for patients with the disease to be seen in centers that are actively involved in IPF research." Better identification and understanding of these differences may provide insights into the pathogenesis of IPF and assist in the development of therapeutic interventions for this devastating lung diseas...

Putting feelings into words produces therapeutic effects in the brain

...eswell said. “We also saw activation in widespread centers of the prefrontal cortex for people who are high in mindfulness. This suggests people who are more mindful bring all sorts of prefrontal resources to turn down the amygdala. These findings may help explain the beneficial health effects of mindfulness...

Research shows cord blood comparable to matched bone marrow
