Cloning Efficiency Of Canine Mesenchymal Stem Cells Isolated From Bone Marrow Of Femoral Head And Subcutaneous Adipose Tissue, Nada Tanamai, Sirirak Chantakru, Monchanok Vijarnsorn

The Thai Journal of Veterinary Medicine

Most recently, adipose tissue (AD) has become an alternative source for mesenchymal stem cells (MSCs) instead of the invasive method of bone marrow (BM) aspiration both in human and canine. In this study, we compared MSCs derived from adipose tissue (AD-MSCs) and bone marrow (BM-MSCs) regarding morphology and cell yield for instant usage by using the standard protocol of counting colony forming unit-fibroblast (CFU-F). MSCs from both sources showed fibroblast-like morphology and formed colonies termed as CFU-F after culturing in plastic surface for 10 days. The colony number per mononuclear cells (MNCs) and the colony number per adherent cells derived …

Mediating Trophoblast Uptake Of Methylaminoisobutyric Acid And Glutamine By Absence Of Extra- Or Intracellular Glutamine, Boonrit Thongsong

The Thai Journal of Veterinary Medicine

Glutamine is known to modulate the uptake activity of nutrient transporters in mammalian cells. The aim of the study was to elucidate the influence of absence of extra- or intracellular glutamine on the uptake activity of the amino acid transport system A in placental BeWo cells. Extracellular glutamine was absent by culturing the cells in regular medium without glutamine. Intracellular glutamine was depleted by culturing the cells in regular medium without glutamine and by treating the cells for 16 hours with methionine sulfoximine (MSX), an inhibitor of glutamine synthetase. When BeWo cells were treated with glutamine-free culture medium for 1-30 …

Role Of An Iron-Dependent Transcriptional Regulator In The Pathogenesis And Host Response To Infection With Streptococcus Pneumoniae., Radha Gupta, Minny Bhatty, Edwin Swiatlo, Bindu Nanduri

CVM Publications

Iron is a critical cofactor for many enzymes and is known to regulate gene expression in many bacterial pathogens. Streptococcus pneumoniae normally inhabits the upper respiratory mucosa but can also invade and replicate in lungs and blood. These anatomic sites vary considerably in both the quantity and form of available iron. The genome of serotype 4 pneumococcal strain TIGR4 encodes a putative iron-dependent transcriptional regulator (IDTR). A mutant deleted at idtr (?idtr) exhibited growth kinetics similar to parent strain TIGR4 in vitro and in mouse blood for up to 48 hours following infection. However, ?idtr was significantly attenuated in a …

Neutering Dogs: Effects On Joint Disorders And Cancers In Golden Retrievers, Gretel Torres De La Riva, Benjamin L. Hart, Thomas B. Farver, Anita M. Oberbauer, Locksley L. Mcv Messam, Neil H. Willits, Lynette A. Hart

Endocrinology Collection

In contrast to European countries, the overwhelming majority of dogs in the U.S. are neutered (including spaying), usually done before one year of age. Given the importance of gonadal hormones in growth and development, this cultural contrast invites an analysis of the multiple organ systems that may be adversely affected by neutering. Using a single breed-specific dataset, the objective was to examine the variables of gender and age at the time of neutering versus leaving dogs gonadally intact, on all diseases occurring with sufficient frequency for statistical analyses. Given its popularity and vulnerability to various cancers and joint disorders, the …

The Herpesvirus Vp1/2 Protein Is An Effector Of Dynein-Mediated Capsid Transport And Neuroinvasion, Sofia V. Zaichick, Kevin P. Bohannon, Ami Hughes, Patricia J. Sollars, Gary E. Pickard, Gregory A. Smith

School of Veterinary and Biomedical Sciences: Faculty Publications

Microtubule transport of herpesvirus capsids from the cell periphery to the nucleus is imperative for viral replication and, in the case of many alphaherpesviruses, transmission into the nervous system. Using the neuroinvasive herpesvirus, pseudorabies virus (PRV), we show that the viral protein 1/2 (VP1/2) tegument protein associates with the dynein/dynactin microtubule motor complex and promotes retrograde microtubule transport of PRV capsids. Functional activation of VP1/2 requires binding to the capsid protein pUL25 or removal of the capsid-binding domain. A proline-rich sequence within VP1/2 is required for the efficient interaction with the dynein/ dynactin microtubule motor complex as well as for …

Mature mammalian sperm contain a complex population of RNAs some of which might regulate spermatogenesis while others probably play a role in fertilization and early development. Due to this limited knowledge, the biological functions of sperm RNAs remain enigmatic. Here we report the first characterization of the global transcriptome of the sperm of fertile stallions. The findings improved understanding of the biological significance of sperm RNAs which in turn will allow the discovery of sperm-based biomarkers for stallion fertility. The stallion sperm transcriptome was interrogated by analyzing sperm and testes RNA on a 21,000-element equine whole-genome oligoarray and by RNA-seq. …

Of the Orthomyxoviridae family of viruses, only influenza A viruses are thought to exist as multiple subtypes and has nonhuman maintenance hosts. In April 2011, nasal swabs were collected for virus isolation from pigs exhibiting influenza-like illness. Subsequent electron microscopic, biochemical, and genetic studies identified an orthomyxovirus with seven RNA segments exhibiting approximately 50% overall amino acid identity to human influenza C virus. Based on its genetic organizational similarities to influenza C viruses this virus has been provisionally designated C/Oklahoma/1334/2011 (C/OK). Phylogenetic analysis of the predicted viral proteins found that the divergence between C/OK and human influenza C viruses was …

Horses were domesticated from the Eurasian steppes 5,000-6,000 years ago. Since then, the use of horses for transportation, warfare, and agriculture, as well as selection for desired traits and fitness, has resulted in diverse populations distributed across the world, many of which have become or are in the process of becoming formally organized into closed, breeding populations (breeds). This report describes the use of a genome-wide set of autosomal SNPs and 814 horses from 36 breeds to provide the first detailed description of equine breed diversity. F(ST) calculations, parsimony, and distance analysis demonstrated relationships among the breeds that largely reflect …

Effects Of Housing System, Slaughter Age, And Sex On Slaughter And Carcass Traits Of Native Turkish Ducks, Mehmet Sari, Kadi̇r Önk, Serpi̇l Işik, Muammer Ti̇lki̇, Tuncay Tufan Jan 2013

Effects Of Housing System, Slaughter Age, And Sex On Slaughter And Carcass Traits Of Native Turkish Ducks, Mehmet Sari, Kadi̇r Önk, Serpi̇l Işik, Muammer Ti̇lki̇, Tuncay Tufan

Turkish Journal of Veterinary & Animal Sciences

The purpose of this study was to determine the effects of different housing systems, slaughter age, and sex on slaughter and carcass traits of native Turkish ducks. A total of 133 ducklings were used. One-day-old ducklings were divided into 2 housing groups, a cage system and a deep litter floor system, under uniform conditions. Housing system significantly affected hot carcass, cold carcass, breast, wing, neck, and back percentages (P < 0.05, P < 0.01, and P < 0.001). The results of the current study showed the influence of housing system, sex, and slaughter age on slaughter and carcass traits. The slaughter and carcass traits and feed conversion efficiency were higher in the deep litter floor system than in the cage system for native Turkish ducks. The slaughter and carcass traits of male ducks were higher than those of female ducks. The ideal slaughter weight for native Turkish ducks was reached at 8 weeks, whereas the results for hot carcass weight, cold carcass weight, hot carcass percentage, and cold carcass percentage were better at 10 weeks of age. Therefore, it seems most appropriate to slaughter native Turkish ducks at 10 weeks of age.

Heifers With Low Antral Follicle Counts Have Low Birth Weights And Produce Progeny With Low Birth Weights, Adam F. Summers, Robert A. Cushman, Karl Moline Moline, Jeff Bergman, Andrea S. Cupp Jan 2013

Heifers With Low Antral Follicle Counts Have Low Birth Weights And Produce Progeny With Low Birth Weights, Adam F. Summers, Robert A. Cushman, Karl Moline Moline, Jeff Bergman, Andrea S. Cupp

Nebraska Beef Cattle Reports

To determine the relationship of antral follicle count and heifer BW, reproductive tract characteristics, and first-calf performance, Red Angus-composite heifers were used over three years. High antral follicle count heifers had greater BW from birth through pre-breeding. Progeny birth BW was greater for calves born to high antral follicle count heifers compared to low antral follicle count heifers. Taken together these data indicate a relationship between antral follicle counts and BW through the first breeding season and corresponding progeny, and continues to support a possible link between genes that influence growth and development and establishment of ovarian reserve.

Two experiments evaluated the feeding value of grass hay bales previously treated with CCDS in growing cattle diets. In Experiment 1, heifers fed bales treated with 20% CCDS (DM) gained less than those fed an equal level of dried distillers grains plus solubles and nontreated hay. In Experiment 2, ADG and F:G linearly improved with increasing CCDS levels. Furthermore, supplementing cattle to meet metabolizable protein requirements when fed diets of CCDS and hay did not improve ADG at levels greater than 15% CCDS. Data indicate hay bales previously treated with CCDS are adequate for use in growing diets, confirming that …

Economic Analysis Update: Supplementing Distillers Grains To Grazing Yearling Steers, Stephanie K. Moore, Andrea K. Watson, Terry Klopfenstein Klopfenstein, Galen E. Erickson, Walter H. Schacht

Nebraska Beef Cattle Reports

A seven-year study from 2005-2011 was conducted to evaluate four grazing management strategies for backgrounding yearling steers on smooth bromegrass pastures. Economic budgets were used to calculate profit differences with current (April 2012) market prices. Overall, cattle receiving supplement had greater net returns, lower cost of gain, and lower breakeven prices. In recent years fertilizer prices have increased at a greater rate than land costs in Nebraska, making it more economical to use a lower stocking rate instead of fertilizing pastures. As land prices increase, the incentive to use either N fertilizer or DDGS supplementation increases.

Corn residue is used for forage and feed, but residue removal effects on soil properties and yield is a concern. Residue removal effects on corn yields and soil organic carbon is site specific. Removing 50% of the residue from rain fed sites reduced corn yield by 1.9 bu/ac, whereas removing 40% of the residue from irrigated sites increased corn yield by 15.4 bu/ac. However, removing 53% of the residue increased soil erosion by 30%. Agronomic practices such as reduced tillage, cover crops, or manure may offset residue removal impacts. Residue removal should be based on site-specific characteristics and management, but …

Ongoing research has found body weight (BW) gains of steers supplemented with corn dried distillers grains plus solubles (DDGS) on unfertilized smooth bromegrass pasture (SUPP) to be greater than unsupplemented steers on N fertilized (FERT) and unfertilized, control (CONT) smooth bromegrass pasture. In the seventh year of the study, annual weeds increased to 20%, 9%, and 2% of relative cover within CONT, SUPP, and FERT pastures, respectively. Supplementation of DDGS on unfertilized pastures improves steer BW gains and reduces N inputs while providing intermediate resistance to annual weed invasion. AnnualN fertilization maximizes forage yield and minimizes annual weeds in pasture.
