Putting nurses in charge of colorectal cancer surveillance instead of doctors has shown to reduce the number of unnecessary colonoscopies and the number of cases progressing to cancer. The South Australian audit of 732 colonoscopies over three months in 2015 found that 97 per cent of procedures adhered to Australian guidelines in the nurse-led model while compliance was just 83 […]

A simple scrape or sore might not cause alarm for most people. But for diabetic patients, an untreated scratch can turn into an open wound that could potentially lead to a limb amputation or even death. A Northwestern University team has developed a new device, called a regenerative bandage, that quickly heals these painful, hard-to-treat sores without using drugs. During […]

One of the most severe outcomes of spinal cord injury from car accidents, sports impacts, or other neck trauma, is losing the ability to control breathing, with patients often requiring artificial ventilation for the rest of their lives. Researchers at Jefferson (Philadelphia University + Thomas Jefferson University) recently tested a hydrogel that releases a nerve-protecting agent at the site of […]

In the current issue of Cardiovascular Innovations and Applications , Angeline D. Opina and Wayne J. Franklin from the Baylor College of Medicine and Texas Children’s Hospital, Houston, TX, USA consider the D-transposition of the great arteries. D-transposition of the great arteries (d-TGA) is the second most common cyanotic congenital heart disease (CHD) lesion, accounting for 3-5% of all CHD, […]

During a depressive episode, the ability of the brain to form new brain cells is reduced. Scientists of the Ruhr-Universität Bochum examined how this affects the memory with a computational model. It was previously known that people in an acute depressive episode were less likely to remember current events. The computational model however suggests that older memories were affected as […]

An international team of researchers including USC scientists has found scores of new genetic markers in DNA code that increase prostate cancer risk—powerful knowledge likely to prove useful to detect and prevent the disease. Focusing on DNA of more than 140,000 men worldwide, researchers were able to identify 63 new genetic markers associated with prostate cancer risk. That greatly increases […]

An experimental drug has shown promise as a potential therapy for spinal cord injuries in animal studies. The compound, 4-aminopyridine-3-methanol, works in a similar way as a drug previously developed at Purdue, 4-aminopyridine (4-AP), which has been approved by the U.S. Food and Drug Administration to treat multiple sclerosis. Dr. Riyi Shi, professor in the Department of Basic Medical Sciences, […]

The clear, colorful rays of light characteristic of precious metals and jewels give us a rich sense of their quality. This is due to our ability to perceive materials, which provides an estimate of the surface condition and material of objects. Humans tend to attribute value to the phenomenon of light reflecting from or passing through the surface of an […]

What makes someone go from simply being hungry to full-on “hangry”? More than just a simple drop in blood sugar, this combination of hunger and anger may be a complicated emotional response involving an interplay of biology, personality and environmental cues, according to research published by the American Psychological Association. “We all know that hunger can sometimes affect our emotions […]

Researchers from the Emory Antibiotic Resistance Center describe the first strain of carbapenem-resistant, hypermucoviscous Klebsiella pneumoniae exhibiting colistin heteroresistance and enhanced virulence isolated from a patient in the United States. The research is presented at ASM Microbe, the annual meeting of the American Society for Microbiology, held from June 7th to 11th, in Atlanta, Georgia. “The problem of antibiotic resistance […]
