Opposites don't always attract. A study from North Carolina State University shows that participants are happier – and perform better – when the electronic helpers used in online training programs resemble the participants themselves. "It is important that the people who design online training programs understand that one size does not fit all," says Dr. Lori Foster Thompson, an associate professor of psychology at NC State and co-author of the study. "Efforts to program helper agents that may be tailored to individuals can yield very positive results for the people taking ...

Manipulation of cells by a new microfluidic device may help clinicians improve a promising cancer therapy that harnesses the body's own immune cells to fight such diseases as metastatic melanoma, non-Hodgkin's lymphoma, chronic lymphocytic leukemia and neuroblastoma. The therapy, known as adoptive T cell transfer, has shown encouraging results in clinical trials. This treatment involves removing disease-fighting immune cells called T cells from a cancer patient, multiplying them in the laboratory and then infusing them back into the patient's body to attack the cancer. ...

New research, funded by the Biotechnology and Biological Sciences Research Council (BBSRC) has shown that nematode worms have to trade-off resistance to different diseases, gaining resistance to one microbe at the expense of becoming more vulnerable to another. This finding, published in PLoS ONE today (2 March 2011), reveals that the worms, called C. elegans, have a much more complex immune system than was previously thought and shows how important such trade-offs are across the animal kingdom. Dr Robin May from the University of Birmingham's School of Biosciences who ...

MedReturn LLC has been researching, developing, and testing a safe and secure method to collect expired prescription medication for the past three years. The effort culminated with development of a unique metal enclosure that is currently being placed in police departments and sheriff's offices across the country.

It makes it possible ...

Boston, MA - Melatonin is known to have cancer-protective properties, and shift work can induce desynchrony of the circadian system, reducing melatonin production. Shift work has been thought to have important health impacts, with evidence linking shift work to an increased risk of several cancers including breast, endometrial, prostate, and colorectal, and non-Hodgkin lymphoma. In a recent study, researchers at Brigham and Women's Hospital (BWH) found that shift work may be associated with a reduced risk of skin cancer in women. These findings are published online in ...

Not all the terrain of the same vineyard has the same properties. Research undertaken by Neiker-Tecnalia (the Basque Institute for Agricultural Research and Development) confirmed that, over the same zone of cultivated land, there are plots with soils of different characteristics, a fact which gives rise to significant differences in the production of the grape and in the quality of the must. Knowing these differences enables the winegrowers to carry out zoning on their vineyards with the goal of better adapting to the needs of fertilisation, irrigation and treatment of ...

German researchers have found a significant association of IL28B genotypes to interferon-based antiviral treatment outcome, and to graft inflammation caused by hepatitis C virus (HCV). The study determined that the presence of G-allele serves as a marker for severe HCV-induced graft inflammation, as well as a predictor for unsuccessful treatment. Study findings—the largest to report on the role IL28B variants in a transplant cohort with recurrent HCV—are published in the March issue of Liver Transplantation, a journal of the American Association for the Study of Liver Diseases. The ...

Turmeric, a bright yellow spice from south Asia belonging to the ginger family, is the main ingredient in curries — and ancient wisdom suggests that it's also good for your health. Taking this wisdom to the laboratory, Tel Aviv University researchers have discovered that turmeric's active ingredient called curcumin amplifies the therapeutic activity of highly toxic anti-inflammatory drugs used to fight colon cancer when used at high doses. Dr. Shahar Lev-Ari of Tel Aviv University's School of Public Health at the Sackler Faculty of Medicine and his colleagues have found ...

Fire, cattle and even prairie dogs all could play a role in sustaining the biodiversity of the western Great Plains, according to a U.S. Department of Agriculture (USDA) researcher. As large grazers, cattle now perform the historical role of buffalo on the Great Plains. Ecologist David Augustine and his colleagues-in collaboration with state, federal, and university researchers-have results from several studies over the past 13 years showing that fire, cattle and prairie dogs together maintain a mosaic of diverse vegetation, with varying vegetation heights, that supports ...

COLLEGE STATION — Researchers have come closer to understanding how a common fungus "makes its living in the soil," which could lead to its possible "career change" as a therapeutic agent for plant and human health. That's according to Dr. Charles Kenerley, Texas AgriLife Research plant pathologist, and a team of scientists from the U.S., India and France, whose study on Trichoderma virens is in February's Journal of Biological Chemistry. T. virens already enjoy a good reputation in the plant world. The fungi is found throughout the world in all types of soil, Kenerley ...

A team of scientists has described two cladocerous crustaceans, which could be endemic to the Iberian Peninsula, and which were found in two lagoons, one in the lower basin of the Guadalquivir river, and the other in the grasslands of Extremadura. Both of these arthropods may today inhabit more areas in the Mediterranean region. "These two new crustaceans (Leydigia) are a species of living fossil and are very powerful bio-geographic and historical indicators", Miguel Alonso, one of the authors of the study, and a researcher in the Department of Ecology of the University ...

For the first time, quantitative—not qualitative—data analysis has demonstrated that time-of-flight (TOF) positron emission tomography (PET) scans can improve cancer detection. Research published in the March issue of the Journal of Nuclear Medicine shows that oncologic TOF fluorodeoxyglucose (FDG) PET scans yielded significant improvements in lesion detection of lung and liver cancers over all contrasts and body mass indexes. Conventional PET scans create images by detecting gamma rays produced by radioisotopes that are injected into the body. Although these conventional ...

To determine if a tissue biopsy reveals the presence of cancer, a histologist often screens for cells with an abnormal appearance or a specific visible trait such as a larger-than-usual nucleus. However, by the time a cancer is physically noticeable, the disease may be in its later stages and more difficult to treat. In an effort to identify the earlier-onset, more subtle chemical changes occurring in a cell heading toward malignancy, researchers at the National Institute of Standards and Technology (NIST) and the National Cancer Institute (NCI) have developed a technique ...

The current edition of JAMIA, today's top-ranked journal in biomedical and health informatics, features new scientific research—in print and online—on some of healthcare's most hotly discussed HIT-related topics, written by prominent experts working in health and biomedicine: "The case for randomized controlled trials to assess the impact of clinical information systems" Joseph L.
