A survey of nearly 700 surgical residents in 17 U.S. medical centers finds that more than half failed to report needle-stick injuries involving patients whose blood could be a source of HIV, hepatitis and other infections.
Most young Singaporean students who will be traveling next week and during July will be vacationing, relaxing and sightseeing. But not 18-year old Nicholas Tan Xue-Wei, who will soon depart for the U.S. to attend ? and present a research paper ? at The 2007 World Congress in Computer Science, Computer Engineering, and Applied Computing (WORLDCOMP’07), June 25 to 28, in Las Vegas.
A research team has identified a new biological function for a soccer ball-shaped nanoparticle called a buckyball ? the ability to block allergic response, setting the stage for the development of new therapies for allergy.
New research, revealing the true extent of abuse suffered by older people in the UK, was released today by Comic Relief, Chief Executive, Kevin Cahill and Health Minster, Ivan Lewis.
University of Pittsburgh School of Medicine investigators have engineered artificial blood vessels from muscle-derived stem cells (MDSCs) and a biodegradable polymer that exhibit extensive remodeling and remain free of blockages when grafted into rats.
Genes account for only 2.5 percent of DNA in the human genetic blueprint, yet diseases can result not only from mutant genes, but from mutations of other DNA that controls genes. University of Utah researchers report in the journal Nature Genetics that they have developed a faster, less expensive technique for mutating those large, non-gene stretches of DNA.
Researchers at the University of Pittsburgh School of Medicine have successfully isolated and cultured human hematopoietic stem cells from fat, or adipose, tissue, suggesting that they have found another important source of cells for reconstituting the bone marrow of patients undergoing intensive radiation therapy for blood cancers.
In a survey of 401 oncology registrars, 102 scored above the threshold for possible psychiatric morbidity and more than one in ten showed clinically important levels of depression. The main reasons cited include being over-stretched, keeping up-to-date with knowledge, fear of making mistakes, talking with distressed relatives, and poor senior support and team relations.
Ram Devireddy, assistant professor of mechanical engineering at LSU, recently co-authored an article with Todd Monroe, assistant professor of biological and agricultural engineering, investigating the complex effects of nanoparticles on cell freezing. The report was published in the prestigious journal Nanotechnology.
The researcher analysed more than 1,500 people between the ages of 18 and 80 and a similar number of men and women. The study concludes that there are no universally good or bad jokes for both women and men, and points out that women have changed their humorous preferences.
