New Microbial Strains In the Human Fecal Microbiota After Obesity Surgery

Using a unique bioinformatics technique, researchers have detected the emergence of new strains of microbes in the human fecal microbiota after obesity surgery. These new strains emerged after surgical disruption of the stomach and upper small intestine. In contrast, the found that strains of the human gut fecal microbiota resembled those found pre-surgery following surgery in the colon.

New Materials Function To ‘Drive Wound Healing’ Naturally

Researchers have developed new bioinspired material that interacts with surrounding tissues to promote healing . Materials are used to heal wounds: Collagen sponges help treat burns and pressure sores, and scaffold-like implants are used to repair bones. Now scientists are developing biomaterials that interact with tissues as healing takes place.

Essential Nutrient Might Be Treatment In Alzheimer's Disease

In a new study, researchers at the Biodesign Institute explore a safe and simple treatment for one of the most devastating and perplexing afflictions: Alzheimer's disease (AD). Lead authors Ramon Velazquez and Salvatore Oddo, along with their colleagues in the ASU-Banner Neurodegenerative Disease Research Center (NDRC), investigate the effects of choline, an essential nutrient that may hold promise in the war against the memory-stealing disorder.

Depression Symptoms And Treatment For Insufficient Responders

Adolescents with depression who were treated with interpersonal psychotherapy (IPT-A) had significantly better outcomes when their therapists prescribed assessed symptoms and augmented treatment for insufficient responders after four weeks of therapy rather than waiting until Week 8, reports  to study  published in the January 2019 issue of the  Journal of the American Academy of Child and Adolescent Psyc hiatry (JAACAP) . 

Role of Lysophospholipid in the Treatment of Alzheimer’s Disease

Researchers report that adding to the lysophospholipid form of EPA (LPC-EPA) to increase dietary levels of EPA in the brain 100-fold in mice. Getting enough of the omega 3 fatty acids DHA and EPA into the brain to study its effects on conditions like Alzheimer's and depression which they have been shown to help – is no easy task. While these are fatty acids, there is scant evidence that these supplements actually increase DHA or EPA in the brain.

A Wireless, Battery-free, Biodegradable Blood Flow Sensor Created

Transforming super-sensitive touch sensors, engineers and medical researchers build a way to wirelessly monitor blood flow after surgery.  A new device developed by Stanford University researchers could make it easier for doctors to monitor the success of blood vessel surgery. The sensor, detailed in a paper published in Nature Biomedical Engineering, monitors the flow of blood through an artery. It is biodegradable, battery-free and wireless, so it is compact and doesn't need to be removed and it can warn a patient's doctor if there is a blockage.
