Soap and water work best in ridding hands of disease viruses
The largest, most comprehensive study ever done comparing the effectiveness of hand hygiene products shows that nothing works better in getting rid of disease-causing viruses than simply washing one's hands with good old-fashioned soap and water.  more

Tumor-targeted immune cells cure prostate cancer in mice without causing systemic immune suppression
In a major breakthrough in cancer gene therapy, a Northwestern University researcher has endowed immune cells with the ability to specifically target metastatic prostate cancer in mice without causing the toxic immune suppression that has been associated with earlier forms of cancer gene therapy.  more

Radiography used to identify teens with sleep apnea
Fifteen percent of all teenagers in the United States undergo orthodontic treatment. Craniofacial Risk Index (CRI) scores, calculated from the radiographs routinely obtained on all orthodontic patients, correctly classified 80% of apneic and 78% of non-apneic adult snorers into high- and low-Respiratory Disturbance Index (RDI) groups. (Sleep apnea is a temporary suspension of breathing during sleep, with potentially serious consequences.) Researchers at Case Western Reserve University (Cleveland, OH) wondered whether similar radiographic use could identify adolescent orthodontic patients with high RDI scores.  more

The case: Preventable rash
This case highlights the danger of inadequate follow-up of outpatient tests and the challenges in the recognition and diagnosis of syphilis and other sexually transmitted diseases (STDs). Just as important, given a potentially transmissible disease, the case provides an opportunity to examine the process of reporting diseases to public health entities and the associated pitfalls.  more

Brain imaging suggests how higher education helps to buffer older adults from cognitive decline
College seems to pay off well into retirement. A new study from the University of Toronto sheds light on why higher education seems to buffer people from cognitive declines as they age. Brain imaging showed that in older adults taking memory tests, more years of education were associated with more active frontal lobes – the opposite of what happened in young adults. It appears possible that education strengthens the ability to "call in the reserves" of mental prowess found in that part of the brain.  more

Silence the gene, save the cell: RNA interference as promising therapy for ALS
Scientists at the Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland have used RNA interference in transgenic mice to silence a mutated gene that causes inherited cases of amytrophic lateral sclerosis (ALS), substantially delaying both the onset and the progression rate of the fatal motor neuron disease. Their results will be published in the April issue of Nature Medicine, and in the journal's advanced online publication 13 March. more
