"Osteopathic medicine is one of the fastest-growing segments of the health care professions in the U.S.," said Dr. Baker. "As our profession grows younger and move diverse, we need their voices to help lead us into what is clearly a very bright future for our distinct philosophy of medicine." Dr. Baker is a clinical associate professor at the University of North Texas Health Science Center, Texas College of Osteopathic Medicine (UNTHSC/TCOM), where he previously served as acting chair and course director for the Department of Radiology and as a member of the teaching faculty for the Department of Gross Anatomy. A graduate of UNTHSC/TCOM, Dr. Baker completed a residency in diagnostic radiology at Fort Worth Osteopathic Medical Center and has served as president of the Texas Osteopathic Medical Association. He is also a member of the American Osteopathic College of Radiology. Also Saturday, delegates named AOA Trustee William S. Mayo, DO, president-elect of the AOA.  Dr. Mayo is a board-certified ophthalmologist practicing in Oxford, Tennessee and is a clinical instructor at the William Carey University College of Osteopathic Medicine.  His term will begin in July 2018. The American Osteopathic Association (AOA) represents more than 129,000 osteopathic physicians (DOs) and osteopathic medical students; promotes public health; encourages scientific research; serves as the primary certifying body for DOs; and is the accrediting agency for osteopathic medical schools.

About the AOA House of Delegates The AOA's House of Delegates, comprised of more than 500 delegates representing osteopathic state medical associations, specialty societies, interns, residents and students from throughout the country, meets annually in July to set organizational policies and elect new officers.

The results show that the OMT protocol employed in the present study improved the postural stability of healthy elderly patients as measured by the force platform in the AP and ML directions. The reduction in AP direction sway, is particularly important because of the greater likelihood of falls associated with AP instability. However, further study is required to demonstrate the correlation between OMT reduced sway observed in this study and fewer falls in the elderly. Nevertheless, it is promising that in both AP and ML directions, the OMT group showed changes in a short 4 week time period towards decreased sway (positive changes from week 1) and therefore towards improved balance and posture. Improved postural stability in elderly patients may have a significant impact in healthcare and the economy because of a reduction in the morbidity and mortality associated with falls in the elderly.

Oxidative stress-induced retinal pigment epithelial (RPE) cell damage is an important factor in the pathogenesis of age-related macular degeneration (AMD). Previous studies have shown that RTA 408, a synthetic triterpenoid compound, potently activates Nrf2. This study aimed to investigate the protective effects of RTA 408 in cultured RPE cells during oxidative stress and to determine the effects of RTA 408 on Nrf2 and its downstream target genes. Primary human RPE cells were pretreated with RTA 408 and then incubated in 200μM H2O2 for 6h. Cell viability was measured with the WST-8 assay. Apoptosis was quantitatively measured by annexin V/propidium iodide (PI) double staining and Hoechst 33342 fluorescent staining. Reduced (GSH) and oxidized glutathione (GSSG) were measured using colorimetric assays. Nrf2 activation and its downstream effects on phase II enzymes were examined by Western blot. Treatment of RPE cells with nanomolar ranges (10 and 100nM) of RTA 408 markedly attenuated H2O2-induced viability loss and apoptosis. RTA 408 pretreatment significantly protected cells from oxidative stress-induced GSH loss, GSSG formation and decreased ROS production. RTA 408 activated Nrf2 and increased the expression of its downstream genes, such as HO-1, NQO1, SOD2, catalase, Grx1, and Trx1. Consequently, the enzyme activities of NQO1, Grx1, and Trx1 were fully protected by RTA 408 pretreatment under oxidative stress. Moreover, knockdown of Nrf2 by siRNA significantly reduced the cytoprotective effects of RTA 408. In conclusion, our data suggest that RTA 408 protect primary human RPE cells from oxidative stress-induced damage by activating Nrf2 and its downstream genes. © 2015.

Metal-enhanced fluorescence (MEF) increased total photon emission of Cy3- and Cy5-labeled ribosomal initiation complexes near 50 nm silver particles 4- and 5.5-fold, respectively. Fluorescence intensity fluctuations above shot noise, at 0.1-5 Hz, were greater on silver particles. Overall signal-to-noise ratio was similar or slightly improved near the particles. Proximity to silver particles did not compromise ribosome function, as measured by codon-dependent binding of fluorescent tRNA, dynamics of fluorescence resonance energy transfer between adjacent tRNAs in the ribosome, and tRNA translocation induced by elongation factor G. © 2011 American Chemical Society.

Shoulder-related pain in the general adult population has been estimated to be between 6.9 and 26% (potentially 1 in 4 people will experience shoulder dysfunction in their lifetime). Thirty age and gender matched subjects were tested using a specially designed device to measure torque during internal/external shoulder rotation. Subjects with shoulder pain had a decreased shoulder range of motion and increased torque at full internal and external rotation. This device was able to objectively distinguish the amount of stiffness between two populations of subjects. Copyright © 2013 by ASME.

Alzheimer disease is a devastating neurodegenerative disorder affecting millions of Americans. It reduces the ability of the individual to remain independent, places a burden on caregivers, and substantially increases healthcare costs. New treatments are being tested in numerous clinical trials with the goal of preventing or delaying the onset of Alzheimer disease, slowing or modifying the disease's course, or finding a cure for patients with the disease. Alzheimer disease research can successfully proceed only if individuals who have this illness are willing to participate in clinical trials. However, recruitment and retention of subjects in clinical trials for Alzheimer disease is a challenging task. Furthermore, because of reductions in decision making capacities of individuals with Alzheimer disease, clinical trials also need to involve caregivers. The present article delineates unique hurdles encountered in the recruitment process for Alzheimer disease clinical trials. The article also identifies strategies for effective recruitment of subjects in Alzheimer disease clinical trials, including guidelines to help principal investigators and clinical research coordinators reach recruitment goals.
