Neuropathy and other nerve problems during cancer treatment

submitted by: mdanderson
Download from iTunes: During cancer treatment, adverse nerve and muscular side effects are common. Unfortunately, there is no treatment that will prevent these conditions, but there are therapies to help relieve these side effects. Ivo Tremont, M.D., and Karin Woodman, M.D., both assistant professors in Neuro-Oncology at MD Anderson Cancer Center, discuss some of the common neurologic and muscular disorders that...

Headset uses ear muscle signals for hands-free control – CES 2015

submitted by: nsf
Can you wiggle your ears? If so, you're a prime candidate to try out a new headset from Reach Bionics. The small business has created technology that harnesses EMG signals from ear muscles. The creators demonstrated the device at the 2015 International CES Eureka Park. Even if you're not an obvious ear-wiggler, the hands-free controller can respond to muscle signals to control a computer cursor, motorized wheelchair or video game. Learn more:

Making Muscle: Tissue Engineering in MUSC's Department of Surgery

submitted by: mcgheek
Samir Fakhry, M.D., Chief of MUSC's Division of General Surgery, and Michael Yost, PhD, Associate Chair of Research in MUSC's Department of Surgery, discuss the promise of engineered tissues for the treatment of surgical and trauma patients. Engineered tissue can instruct the body to regenerate native tissue instead of generating scar, improving cosmetic and functional outcomes. Bioprinters, 3D printers for living tissue, will help realize the promise of engineered tissue for clinical care.k

Dietary Selenium Deficiency Partially Rescues Type 2 Diabetes–Like Phenotypes of Glutathione Peroxidase-1–Overexpressing Male Mice

submitted by: xlei
This study was conducted to determine whether dietary Se deficiency precluded overproduction of glutathione peroxidase-1 (GPX1) activity in mice overexpressing (OE) this gene and thus rescued their type 2 diabetes–like phenotypes. A total of 20 male OE and wild-type (WT) mice were fed an Se-deficient (<0.02 mg/kg) diet or an Se-supplemented (0.3 mg/kg as sodium selenite) diet from 1 to 5 mo of age. Dietary Se deficiency eliminated or attenuated (P < 0.05) genotype differences in...

Octanoate and Nonanoate Oxidation Increases 50-80% Over the First Two Days of Life in Piglet Triceps Brachii and Gracilis Muscle Strips

submitted by: Thomas D. Crenshaw
An in vitro muscle strip incubation system was developed to measure the rate of catabolism of 1 mmol/L [1-14C]octanoate, 1 mmol/L [1-14C]nonanoate, 1mmol/L [9-14C]nonanoate and 10 mmol/L [U-14C]glucose by measuring the recovery of 14CO2. Muscle strips (13 mm?1.5 mm ~50 mg) were isolated from triceps brachii and gracilis muscles of newborn and 2 d old, small (<950 g) and large (>1450 g) piglets. The position of the 14C label in the substrate affected the rate and amount of recovery in...

The R403Q Myosin Mutation Implicated in Familial Hypertrophic Cardiomyopathy Causes Disorder at the Actomyosin Interface

submitted by: apryl
Background Mutations in virtually all of the proteins comprising the cardiac muscle sarcomere have been implicated in causing Familial Hypertrophic Cardiomyopathy (FHC). Mutations in the β-myosin heavy chain (MHC) remain among the most common causes of FHC, with the widely studied R403Q mutation resulting in an especially severe clinical prognosis. In vitro functional studies of cardiac myosin containing the R403Q mutation have revealed significant changes in enzymatic and...
