Stress substantially slows human body's ability to heal

...r minor wounds says that wound-healing is a really sensitive process." Glaser added, "This supports our long-held contention that even small changes in cytokine levels will have a marked effect on health."

Scythe balances life and death during development

... put Scythe genes back into the cells, they became sensitive to these treatments and underwent apoptosis. "These chemicals affect the movement of calcium inside a special structure where proteins are made," McKinnon said. "This showed that Scythe helps trigger apoptosis in specific circumstances. Further stud...

National study improves outcome for pediatric AML

... of failure, and guided by the results of a highly sensitive technique for identifying leukemic cells, yielded one-year survival rates of almost 90 percent, according to investigators at St. Jude Children's Research Hospital and a national consortium of research institutes. The ongoing clinical trial, called ...

Parents of children with cancer suffer post-traumatic stress symptoms, both immediate and lingering

The Children's Hospital researchers recently published two studies of posttraumatic stress (PTS) symptoms in mothers and fathers of children with cancer. ...

Evidence links cocaine abuse and Parkinson's disease

...aine altered the nigrostriatal system so it became sensitive to MPTP. Exposure to cocaine did not affect the number of cells in the SNpc of adult and fetal models but did make them more susceptible to damage from MPTP, the researchers reported. Furthermore, in both the adult and fetal models, cocaine exposure...

Blood test can accurately diagnose heart failure in patients with kidney dysfunction

...ear, the PRIDE study showed NT-proBNP to be highly sensitive and specific for the diagnosis of acute heart failure in patients with shortness of breath and to strongly predict patient deaths. A major concern about the widespread use of the marker had been previous assertions that kidney disease very common i...

...ter cells which can result in a cancer that is not sensitive to treatment, Wei says. If you think of a chromosome as walls that hold up the house, which is the cell, and DNA as individual bricks, then in common squamous and basal cell carcinoma, UV in sunlight knocks down the walls, and usually these cells d...

Raising alcohol prices can lead to more drinking instead of less

...sales will be large. Policy makers should be very sensitive to the manner in which alcohol distributors can pass a tax on to consumers. This study shows that the manner in which a tax is passed on to the consumer can be the primary determinant of its effects on use and problems." Gruenewald cautioned, ho...

New technology developed at Barrow Neurological Institute enhances MRI capabilities

...d "Diffusion Weighted Imaging (DWI)," is extremely sensitive to even minute motion in a patient. Prior to PROPELLER, DWI images suffered in quality because the methods used to reduce this motion sensitivity also reduced image quality. With PROPELLER DWI, small strokes are much easier to detect, grade and follo...

Soy diet worsens heart disease

...circulating levels of estrogen compounds, are less sensitive than males to the change in estrogen level as a result of the soy diet. Interestingly, the authors observed a significant improvement in cardiac growth and function when the animals were switched to a soy-free diet. The new data provide a strong link...

In addition to Harris and Gordon-Larsen, other authors are Kim Chantala, research associate at the Carolina Population Center; and D...

Point-of-care test proves more effective for recurrent bladder cancer than conventional lab test

...rs. In this case, the NMP22 was significantly more sensitive than urine cytology, which only detected three of these cases. While Grossman is optimistic about the benefits of the NMP22 assay, he cautions it still should be performed in conjunction with a cystoscopy, which is considered the "gold standard" for ...
