MS researchers find well-being differs with age in multiple sclerosis
(Kessler Foundation) The oldest group reported the lowest levels of depressive symptoms and the highest levels of Physical QOL. 'These results were unexpected,' said Dr. Strober, 'given the functional limitations, disease progression, and neurological lesions seen in the aging MS population. Contrary to our hypothesis, the trend by age paralleled the general population. Younger individuals with MS are at greater risk for depression and poor QOL. If confirmed, targeted screening for depression by age may be warranted in this population.'

UMN researchers discover influenza virus doesn't replicate equally in all cells
(University of Minnesota Medical School) The seasonal flu is caused by different subtypes of Influenza A virus and typically leads to the death of half a million people each year. In order to better understand this virus and how it spreads, University of Minnesota Medical School researchers took a closer look at the cells inside the lungs. What they discovered is not only is the immune system response tuned to the amount of virus replication, it's also tuned to the viral spread.

Researchers develop microbubble scrubber to destroy dangerous biofilms
(University of Illinois at Urbana-Champaign) Stiff microbial films often coat medical devices, household items and infrastructure such as the inside of water supply pipes, and can lead to dangerous infections. Researchers have developed a system that harnesses the power of bubbles to propel tiny particles through the surfaces of these tough films and deliver an antiseptic deathblow to the microbes living inside.

Viral RNA sensing
(Wiley) Even tiny amounts of viruses can have disastrous consequences. RNA identification can reveal the type of virus present. A fast and sensitive technique based on optical detection has now been outlined in the journal Angewandte Chemie. Scientists from Germany and Finland have demonstrated the binding of an RNA target to a probe made of gold nanorods and a DNA origami structure. Chirality switches triggered by binding can be measured by circular dichroism spectroscopy.

Newborn opioid withdrawal requires a 'cascade of care,' study suggests
(Wolters Kluwer Health) Effective management of neonatal abstinence syndrome (NAS) -- withdrawal symptoms occurring in infants exposed to opioids in utero -- requires a coordinated 'cascade of care' from prevention through long-term follow-up, reports a study in Advances in Neonatal Care, official journal of the National Association of Neonatal Nurses. The journal is published in the Lippincott portfolio by Wolters Kluwer.

New insight into aging
(McGill University) Researchers at the Montreal Neurological Institute and Hospital (The Neuro) of McGill University examined the effects of aging on neuroplasticity in the primary auditory cortex, the part of the brain that processes auditory information. Neuroplasticity refers to the brain's ability to modify its connections and function in response to environmental demands, an important process in learning.

Anti-inflammatory protein promotes healthy gut bacteria to curb obesity
(University of North Carolina Health Care) Scientists from the UNC School of Medicine discovered that the anti-inflammatory protein NLRP12 normally helps protect mice against obesity and insulin resistance when they are fed a high-fat diet. The researchers also reported that the NLRP12 gene is underactive in people who are obese, making it a potential therapeutic target for treating obesity and diabetes, both of which are risk factors for cardiovascular disease and other serious conditions.
