End-of-life care can be improved

... Palliative and end-of-life care in the ICU is an appropriate and under-developed area for quality assessment and improvement, according to Richard Mularski, M.D., M.S.H.S., from the Veterans Affairs Greater Los Angeles Healthcare System. Dr. Mularski and a number of the other contributors to this supplement c...

Free drug samples influence prescribing, say one in three doctors

Chronic pain up almost 40 percent among US workers in past decade

...nd work with their healthcare provider to identify appropriate treatment options." Chronic pain, defined in the survey as pain that lasts for at least six months, was more common in the workplace in 2006 than it was in 1996 (26 percent vs. 19 percent). Today, almost nine in 10 employees with chronic pain (...

NYU scientists identify how development of different species uses same genes with distinct features

...nderstood by biologists and therefore serves as an appropriate focus for genetic analyses. In this study, the researchers sought to explore the generality of developmental mechanisms by comparing Drosophila with Nasonia, a distant species that diverged over 250 million years ago but one that presents many morpho...

She adds that appropriate amounts of juices should be included in the diet of both children and adults, following guidelines established by leading health authorities. Taylor also points to a large epidemiological study, published in the September 2006 issue of the Journal...

Groundbreaking Canadian asthma study

...cognized that this procedure might therefore be an appropriate treatment for people with asthma." "I’m quite pleased to say that our experience suggests that the Bronchial Thermoplasty procedure is quite well-tolerated, and it holds considerable promise for patients with asthma." Asthma is a common diseas...

...ty to develop into different types of cells in the appropriate environment. One donation can produce billions of MSCs. The cells can be stored for years in a frozen state, ready to be used when they are needed." Adult stem cells are designed by nature to perform tissue repair in a mature adult. It is believed...

Tissue engineering for craniofacial reconstruction

...-engineering paradigm combines isolated cells with appropriate bioactive agents in a biomaterial scaffold. It is widely recognized that scaffold architecture can profoundly influence the behavior of cells on tissue-engineering constructs. Today, during the 85th General Session of the International Association f...

Scientists re-grow dental enamel from cultured cells

...namel, as long as they were later provided with an appropriate environment. The idea for the culturing technique originates from 1975, when Dr. J.G. Rheinwald and Dr. H. Green of Harvard Medical School reported the use of feeder layers for culturing epithelial cells from the skin (the 3T3-J2 cells used in the...

Scientists produce neurons from human skin

...rate and differentiate in vitro when placed in the appropriate environment. They progressively took on the oblong shape typical of neurons. At the biochemical level, researchers discovered that in the days following the start of the experiment, the cells began producing markers and molecules associated with the ...

Holzapfel, researchers in the department of biology and members of the UO Center for Ecology and Evolutionary Biology. "For the first time, we are moving down the track to identify genes that ani...

Freeze! Scientists film proteins at work by freezing them at different states

...them with strong evidence that the states were the appropriate ones by showing them the chemical bonds in each stage of the reaction. Once they had identified the right states, they studied the sample with synchrotron x-rays. “We expect this new methodology to be of use for many researchers in the field? Bourgeo...

Hofmeyr skull supports the 'Out of Africa' theory

...n Eurasia. Until now, the lack of human fossils of appropriate antiquity from sub-Saharan Africa has meant that these competing genetic models of human evolution could not be tested by paleontological evidence. The skull from Hofmeyr has changed that. The surprising similarity between a fossil skull from the s...

Bacteria control how infectious they become, study finds

...ed,?Svetlov said. It's only when RfaH finds the appropriate target sequence on a bacterium's DNA that this small portion of the protein is unmasked and can then turn on a select group of genes. These genes let disease-causing bacteria infect their host while at the same time protecting the bacteria from the h...
