Mitochonic Acid 5 (MA-5), a Derivative of the Plant Hormone Indole-3-Acetic Acid, Improves Survival of Fibroblasts from Patients with Mitochondrial Diseases. Tohoku J Exp Med. 2015;236(3):225-32 Authors: Suzuki T, Yamaguchi H, Kikusato M, Matsuhashi T, Matsuo A, Sato T, Oba Y, Watanabe S, Minaki D, Saigusa D, Shimbo H, Mori N, Mishima E, Shima H, Akiyama Y, Takeuchi Y, Yuri A, Kikuchi K, Toyohara T, Suzuki C, Kohzuki M, Anzai J, Mano N, Kure S, Yanagisawa T, Tomioka Y, Toyomizu M, Ito S, Osaka H, Hayashi K, Abe T Abstract Mitochondria are key organelles implicated in a variety of processes related to energy and free radical generation, the regulation of apoptosis, and various signaling pathways. Mitochondrial dysfunction increases cellular oxidative stress and depletes ATP in a variety of inherited mitochondrial diseases and also in many other metabolic and neurodegenerative diseases. Mitochondrial diseases are characterized by the dysfunction of the mitochondrial respiratory chain, caused by mutations in the genes encoded by either nuclear DNA or mitochondrial DNA. We have hypothesized that chemicals that increase the cellular ATP levels may ameliorate the mitochondrial dysfunction seen in mitochondrial diseases. To search for the potential drugs for mitochondrial diseases, we screened an in-house chemical library of indole-3-acetic-acid analogs by measuring the cellular ATP levels in Hep3B human hepatocellular carcinoma cells. We have thus identified m...

The American Congress of Rehabilitation Medicine (ACRM) offers an opportunity for members to be the guest editor of a Supplement to its journal, the Archives of Physical Medicine and Rehabilitation (Archives). The goal of the ACRM supplements is to publish high quality scientific manuscripts, which are thematically organized and of interest to ACRM members and to the general readership of the Archives. We are interested in proposals in all fields of rehabilitation, but especially those of interest to the ACRM membership as indicated by the existence of special interest and networking groups for brain injury, spinal cord in...

Publication date: Available online 24 February 2020Source: Biochimica et Biophysica Acta (BBA) - Molecular and Cell Biology of LipidsAuthor(s): Maya W. Haaker, Arie B. Vaandrager, J. Bernd HelmsAbstractVitamin A (retinol) is important for normal growth, vision and reproduction. It has a role in the immune response and the development of metabolic syndrome. Most of the retinol present in the body is stored as retinyl esters within lipid droplets in hepatic stellate cells (HSCs). In case of liver damage, HSCs release large amounts of stored retinol, which is partially converted to retinoic acid (RA). This surge of RA can med...

Abstract The National Institutes of Health Stroke Scale (NIHSS) is considered the standard for assessing neurologic status after an acute stroke. Currently, there is no guideline for when this assessment should be completed, nor is there consensus on how frequently or for how long.We initiated a quality improvement project that sought first to determine when and how often nurses at a variety of institutions in our multisite health care system completed the NIHSS assessment and then to identify the minimum frequency at which nurses should complete the assessment. After reviewing the literature and current practices...
