School of Veterinary and Biomedical Sciences: Faculty Publications

Nonalcoholic steatohepatitis (NASH) patients have elevated plasma saturated free fatty acid levels. These toxic fatty acids can induce liver cell death and our recent results demonstrated that the biliary epithelium may be susceptible to lipotoxicity. Here, we explored the molecular mechanisms of cholangiocyte lipoapoptosis in cell culture and in an animal model of NASH. Treatment of cholangiocytes with palmitate (PA) showed increased caspase 3/7 activity and increased levels of cleaved poly (ADP-ribose) polymerase and cleaved caspase 3, demonstrating cholangiocyte lipoapoptosis. Interestingly, treatment with PA significantly increased the levels of microRNA miR-34a, a pro-apoptotic microRNA known to be elevated in NASH. …

Israel : Translocation Of Rabies, Sarah Baker Jan 2017

Israel : Translocation Of Rabies, Sarah Baker

Global Public Health

Israel is now faced with a steady growing public health threat as canine rabies has reemerged in the northern region of Israel. While the steady increase in cases is of notable alarm, moreover the close contact most often shared between dog and human populations is of much more concern from a public health prospective. Rabies is a vaccine-preventable disease. Vaccinating dogs has proven to be the most cost-effective strategy for preventing rabies in people. Additionally, education on bite prevention and rabid animal behaviors for both children and adults is an essential extension of the long term rabies vaccination program that …

Relationship Between Dietary Total Digestible Nutrients And Digestible Organic Matter In Beef Cattle Finishing And Growing Diets With Or Without Distillers Grains, Hannah C. Hamilton, Jana L. Gramkow, Jim C. Macdonald Donald, Galen E. Erickson, Andrea K. Watson, Terry J. Klopfenstein

Nebraska Beef Cattle Reports

The relationship between organic matter digestibility and total digestible nutrients is unestablished for diets containing distillers grains. Three cattle digestion studies were used to evaluate the relationship between total digestible nutrients and digestible organic matter. Results suggest digestible organic matter is consistent relative to total digestible nutrients content for traditional, corn based diets. In finishing and growing diets containing distillers grains additional digestible energy supplied by distillers grains is not accounted for when evaluating only digestible organic matter. Measuring digestible energy content of diets used in digestion trials is essential.

Effect Of Salt Reduction On The Quality And Shelf Life Characteristics Of Deli-Style Roast Beef, Chad G. Bower, Regan E. Stanley, Samodha Fernando Fernando, Gary A. Sullivan Jan 2017

Effect Of Salt Reduction On The Quality And Shelf Life Characteristics Of Deli-Style Roast Beef, Chad G. Bower, Regan E. Stanley, Samodha Fernando Fernando, Gary A. Sullivan

Nebraska Beef Cattle Reports

Concerns with excessive sodium intake have led to increased pressure on meat processors to reduce added salt in meat products. Quality characteristics and microbial growth were evaluated on deli- style roast beef slices formulated to contain varying concentrations of added salt. Salt concentration had no effect on microbial community composition, however increasing salt slowed microbial growth over time. Increasing salt increased cooking yield and decreased water activity. Salt reduction negatively impacts the texture, yield, and shelf life of deli- style roast beef, however salt concentrations within this range do not significantly alter spoilage flora community composition.

Organic Acids And Applications Used For Reduction Of E. Coli On Beef Shoulder Clods Used For Ground Beef, Kelly A. Mccarty, Gary A. Sullivan, Dennis E. Burson Burson Jan 2017

Organic Acids And Applications Used For Reduction Of E. Coli On Beef Shoulder Clods Used For Ground Beef, Kelly A. Mccarty, Gary A. Sullivan, Dennis E. Burson Burson

Nebraska Beef Cattle Reports

Small processors normally grind beef shoulder clods for ground beef that have not been previously tested for shiga toxin-producing E. coli. Three antimicrobial solutions were applied using three application methods to beef sub-primals to evaluate the effectiveness of reducing E. coli and the effects on quality attributes. Antimicrobials effectively reduced Rifampicin resistant E. coli. However, none of the treatments changed color attributes or total plate counts compared to a control. These results suggest that an appropriate antimicrobial solution and application method can be selected for use by small meat processors without affecting quality attributes.

The Influence Of Diet And Oxidation On Calcium Retention Of The Mitochondria In Fresh Beef, Emery K. Kunze, Nicolas J. Herrera, Katherine I. Domenech-Perez Perez, Michael D. Chao, Chris R. Calkins

Nebraska Beef Cattle Reports

Feeding dried distillers grains (DG) may influence calcium flux postmortem by disrupting the stability of the sarcoplasmic reticulum (SR) membrane, thus leading to a higher post- rigor calcium leakage, resulting in greater activation of calpains and improved tenderness. Mitochondria provide the opportunity to study calcium flux in a controlled, tightly defined environment as a model system for the SR. Cattle were finished on diets containing either 0% DG or 50% DG. Feeding DG increased proportions of PUFA in the SR and mitochondrial membrane. Oxidized mitochondria retained less calcium than non- oxidized mitochondria. Mitochondria from cattle finished on corn tended to …

Comparison Of Diets Collected From Esophageally Fistulated Cows To Forage Quality Estimated From Fecal Analysis, Bethany M. Johnston, Jay D. Jenkins, Jacqueline A. Musgrave Musgrave, L. A. Stalker, Mitchell B. Stephenson

Nebraska Beef Cattle Reports

Differences in forage quality (crude protein and energy) were analyzed between esophageally fistulated diets, analysis of fecal samples with Nutrition Balance Analyzer (NUTBAL) analysis, and analysis of handclipped forage samples. On upland range sites, hand- clipped samples provided forage quality estimates that were closer to esophageally fistulated diets than samples analyzed with the NUTBAL analysis. Aft er one year of data collection, it appears that there may be some inconstancies with the NUTBAL analysis for estimates on rangeland forage quality in the Nebraska Sandhills. More data is needed to verify these results; however, making management supplementations decisions solely on the …

Evaluation Of Plant- Waxes To Estimate Forage Intake In Grazing Cattle, Hannah C. Hamilton, Jerry D. Volesky, Robert M. Lewis Lewis Jan 2017

Evaluation Of Plant- Waxes To Estimate Forage Intake In Grazing Cattle, Hannah C. Hamilton, Jerry D. Volesky, Robert M. Lewis Lewis

Nebraska Beef Cattle Reports

Although key to the efficiency of a cattle operation, feed intake is challenging to evaluate in a grazing setting. However, even within forage- based systems, plant- wax markers may be used to predict dietary choices and feed intake. Plant- waxes are a complex mixture of lipids found on the surface of plants. When sufficiently unique among plants, the composition of diets can be determined from the pattern of these compounds in the forages ingested. These markers were used to delineate the parts of the corn plant and, separately, 8 western rangeland grasses and legumes. Using plant waxes, the components of …
