Dr. Jeff Ondrak, associate professor at the Great Plains Veterinary Educational Center, will present "Measurement of temperatures in veterinary practice vehicles and evaluation of impact on pharmaceutical concentrations" Feb. 26 in VBS 145 at 4 p.m.

Abstract
The most common upper limits of storage temperatures for U.S.-approved non-refrigerated drugs are 77°F or 86°F. Because ambient temperatures in many locations in the U.S. exceed these temperatures in summer, our objective was to measure storage area temperatures in large animal veterinary practice vehicles to evaluate the extent to which manufacturers’ recommended storage temperatures are exceeded and then determine the effect on the active ingredient concentrations of drug products exposed to these elevated temperatures. Temperatures in storage units in participating veterinary practice vehicles exceeded labelled drug storage temperatures a significant portion of the duration of the trial. No significant impact of elevated storage temperatures on product active ingredient was found in this study. However, the only outcome tested was active ingredient concentration on a limited number of products for 120 days, so practitioners are advised to protect all pharmaceuticals from elevated storage temperatures.

Dr. Chris Martyniuk, associate scientist, Center for Environmental and Human Toxicology and Department of Physiological Sciences, College of Veterinary Medicine, University of Florida, will present the seminar "Molecular pathways underlying mitochondrial dysfunction in dopamine cells: A pesticide perspective," Jan. 29, 2018, in VBS 145 at 4 p.m.

Abstract

Pesticides are ubiquitous on a global scale. Epidemiological and experimental data suggest that long-term pesticide exposure may be associated with neurodegenerative diseases such as Alzheimer’s and Parkinson’s disease (PD). Mechanisms by which pesticides affect the central nervous system are many, and include neuroinflammation, disruptions in neurotransmitters, and mitochondrial dysfunction which can lead to energy deficits with the cell, oxidative stress, and apoptosis. Our research measures metabolic responses in dopamine cells and whole animal models in response to pesticides that are concerns for environmental exposures and PD. We show that these pesticides impair oxidative phosphorylation of dopamine cells and that endoplasmic stress may be involved in the response. A quantitative proteomics approach also reveals that protein networks related to oxidative stress and Parkinson’s disease are perturbed in dopamine cells by paraquat. Lastly, the use of the zebrafish model for pesticide-induced neurological dysfunction will be presented. As an example, our data indicate that paraquat results in hyperactivity and increases the abundance of transcripts related to the dopamine system. The overarching goal is to elucidate how pesticides that are linked to PD affect mitochondrial bioenergetics at the mechanistic level.

Gentry Lewis, laboratory manager in the School of Veterinary Medicine and Biomedical Sciences, received an IANR 2017 Outstanding Employee Award at a luncheon in the Nebraska East Union on Dec. 1, 2017.

The award recognizes individuals who go above and beyond their job responsibilities and demonstrate an excellent work ethic, produce high quality work and have an extraordinary impact within their department.

Gentry has been lab manager for Dr. Rodney Moxley since 2009. She supervises technicians, teaches graduate and undergraduate students laboratory techniques and methods, and “displays an outstanding level of knowledge, technical expertise, intellect and experience,” according to a nomination letter. Another nominator noted that Gentry can be counted on to find the answer to questions “whether it is regarding the operations of the lab, personnel issues, maintenance issues, unknown bills, or vending machines.” It also was noted that Gentry is "kind, courteous, thoughtful and professional, and displays 'common sense.' She has also demonstrated patience and grace in dealing with other employees and graduate students."

OEA recipients receive a cash award and certificate. Congratulations on this well-deserved award, Gentry!

A seven-year national research project led by Nebraska scientists received the Partnership Award from the National Institute of Food and Agriculture, the research arm of the U.S. Department of Agriculture.

The Coordinated Agricultural Project (CAP) on E. coli was recognized for efforts to reduce food-borne illness caused by Shiga toxin-producing E. coli. The award, in the mission integration category, honors the E. coli project for integrating research, education and extension for the benefit of agriculture, the environment, communities or people. Dr. Rodney Moxley, Charles Bessey Professor of Veterinary Medicine and Biomedical Sciences serves as the project director. Read more.

Richard Randle, veterinarian and associate professor in the School of Veterinary Medicine and Biomedical Sciences (SVMBS), was recognized by Nebraska State Fair Board for six years of service managing the Livestock Birthing Pavilion at the Nebraska State Fair. The birthing pavilion provides the opportunity for visitors to witness animal births during the course of the two-week fair. Piglets, dairy and beef calves, ewes and chicks are born under the supervision of veterinarians and other trained professionals from SVMBS and the Nebraska Veterinary Medical Association.

This was Dr. Randle's last year managing the Birthing Pavilion; he will retire this fall.

Dr. Randle joined the University of Nebraska-Lincoln Department of Veterinary and Biomedical Sciences in 2007 as the extension beef cattle veterinarian. He specializes in beef cow/calf production management, and his research interests include young stock management, disease monitoring and quality assurance.
