OHSU researcher’s discovery paves way for improved treatments for hearing-impaired

A team led by Lina A.J. Reiss, Ph.D., assistant professor in the OHSU School of Medicine’s Otolaryngology – Head & Neck Surgery Department, has discovered that as many as half of individuals wearing bilateral hearing devices experience abnormal processing of sounds that worsens their auditory perception, particularly speech recognition. Much progress has been made in the treatment of hearing loss with the development of hearing aids (HA) and more recently, cochlear implants (CI). In particular, combining acoustic and electric hearing from … Read More

Newgard paper is AEM editor-in-chief pick for May 2016

Craig Newgard, M.D., M.P.H., director of OHSU’s Center for Policy and Research in Emergency Medicine, was recently recognized by Academic Emergency Medicine (AEM) for his research on gun violence mapping. Newgard et al.’s paper, “A geospatial analysis of severe firearm injuries compared to other injury mechanisms: Event characteristics, location, timing, and outcomes,” was chosen by AEM’s Editor-in-Chief Jeffrey Kline, M.D., as May’s feature. In this study, Newgard and his team performed a secondary analysis of … Read More

Eric Gouaux’s serotonin transporter research featured by NIH

Recent findings by Vollum Institute senior scientist, Eric Gouaux, Ph.D., and team that reveal the molecular structure of the human serotonin transporter, are getting a lot of attention from the biomedical community and the media. Gouaux’s study was featured in NIH Research Matters, the online publication that highlights groundbreaking NIH-funded discoveries. The article, “Serotonin transporter structure revealed,” discusses the innovative technique developed by the team that allowed them to use X-ray crystallography to capture a 3-D image of the … Read More

Study confirms mitochondrial mutations increase with age, impact stem cell treatments

A team led by Shoukhrat Mitalipov, Ph.D., director of the Center for Embryonic Cell and Gene Therapy at OHSU, has confirmed that mutations in mitochondrial DNA accumulate with age and can limit cells’ ability to create energy and function properly. The study examined induced pluripotent stem (iPS) cells derived from patients’ skin or blood cells and identified faulty DNA, with each cell having potentially different types and percentages of mutations. These defects could undermine the … Read More

Researchers demonstrate the impact of obesity on emergency contraception

OHSU clinical researchers Alison Edelman, M.D., M.P.H., and Jeffrey Jensen, M.D., M.P.H., published a study that examined why emergency contraception isn’t as effective in obese women, and how to potentially increase its effectiveness in this population. The findings, published March 19 in the journal Contraception, show how obesity adversely impacts circulating levels of emergency contraception, and that doubling the dose appears to correct obesity-related interference in the drug’s efficacy. Roughly half of all pregnancies in the U.S. are unintended. Single-dose emergency … Read More

Gouaux lab researchers visualize serotonin transporter structure, create platform for antidepressant drug design

Researchers at OHSU’s Vollum Institute have revealed the molecular structure of the serotonin transporter (SERT), providing new insight into the mechanism of antidepressant action of two widely prescribed selective serotonin reuptake inhibitors (SSRIs) commonly used to treat depression. In their paper, “X-ray structures and mechanism of the human serotonin transporter,” published Apr. 6, in the journal Nature, authors Jonathan Coleman, Ph.D., Eric Gouaux, Ph.D., and Evan Green, describe their use of X-ray crystallography to capture … Read More

TTBD Startup Spotlight: ReelDx, Inc.

ReelDx, Inc. is an OHSU startup company developing secure, HIPAA-compliant medical video platforms for educational and clinical use. Launched in 2013, the company’s initial goal was to improve medical instruction by creating ReelDx Education, a video library of case studies to broaden medical student’s experiences in real-world health care settings. The company has since expanded to incorporate an additional video platform, called medvid.io. This video platform is aimed at improving the patient and physician relationship … Read More

Hessell and ONPRC team discovers antibody treatment that halts SHIV infection in infant macaques

This post has been updated with proper author attribution. OHSU researchers at the Oregon National Primate Research Center have shown that early short-term treatment with human anti-HIV1-1 monoclonal antibodies halts simian HIV infection, a chimeric virus that shares key properties with HIV,  in infant macaques. The study, published March 21 in Nature Medicine, shows that antibodies given to a baby macaque within 24 hours after being exposed to simian HIV can clear the virus completely, … Read More

TTBD Innovator Spotlight: Xiangshu Xiao, PhD

Xiangshu Xiao, Ph.D., associate professor of physiology and pharmacology in OHSU’s School of Medicine, has been at the forefront in the field of cancer chemical biology. The goal of his research is to develop novel cancer therapeutics, using a combination of chemistry and biology, to create new compounds that target deregulated proteins in cancer cells. In his two main cancer-related projects, Dr. Xiao has developed first-in-class compounds that show significant anti-cancer effects in various preclinical … Read More
