The Effect Of Dgat1 Polymorphism On Milk Production Traits In Dairycows Depending On Environmental Temperature, Jolanta Komisarek, Mateusz Kolenda

Turkish Journal of Veterinary & Animal Sciences

It has long been known that a hot environment negatively influences milk production in cattle. Although molecular mechanisms underlying this phenomenon to a great extent remain to be recognized, they include alterations in lipid metabolism. DGAT1 plays a key role in the synthesis of triacylglycerols and polymorphism of this gene has been proven to have a pronounced influence on milk production. The aim of this study was to establish if the effect of DGAT1:p.K232A on milk-related traits is dependent on environmental thermal conditions. The analysis, performed on 468 cows of the Polish Holstein-Friesian breed, showed that allele DGAT1:K232 significantly increased …

The limbs were in good alignment, the calves were fully weight-bearing, and client …

The Effect Of Yucca Schidigera Powder Added To Lamb Feed On Fatteningperformance, Some Blood Parameters, The Immune System, And Theantioxidative Metabolism Of The Hepatic Tissue, Recep Gümüş, Hali̇t İmi̇k

Turkish Journal of Veterinary & Animal Sciences

In this study, Yucca schidigera powder (YSP) added to lamb feed was investigated for its effects on performance, some blood parameters, the immune system, and the antioxidative metabolism of the hepatic tissue. Throughout a 10-week fattening period, twenty-four 2.5-month-old male Akkaraman lambs were used. Three groups were established, including a control group © and groups YSPI and YSPII, which received a basal ration alone, a basal ration + 100 ppm YSP, and a basal ration + 200 ppm YSP, respectively. The groups did not differ for performance parameters (P > 0.05). While 100 ppm YSP increased serum NH3 levels (P < 0.05), 200 ppm YSP significantly decreased serum cholesterol, HDL, LDL, and Mg levels (P < 0.05). The groups did not differ for antibody titers against the Brucella melitensis vaccine (Rev 1). In groups YSPI and YSPII, hepatic CAT activity and LPO levels were significantly lower than those of Group C (P < 0.01). While the GSH levels of group YSPI were significantly higher than those of groups C and YSPII, the SOD activity of group YSPII was significantly lower than those of groups C and YSPI (P < 0.01). As a result, while YSP did not affect the performance parameters or immune system, it significantly affected NH3 levels, lipid metabolism, and the antioxidant system.

Treatment with fermented barley and oats resulted in increased body weight at day 42. Treatment with fermented wheat and oats increased the percentage of carcass yield. Birds fed unfermented grains had highly viscous digesta, not seen among birds …

The Efficacy Of Kaolin Clay In Reducing The Duration And Severity Of `Heat' Diarrhea In Foals, Magdalena Pieszka, Jaroslaw Luszczynski, Magdalena Hedrzak, Katerina Goncharova, Stefan G. Pierzynowski

Turkish Journal of Veterinary & Animal Sciences

'Heat' diarrhea in foals is an onerous but not life-threatening ailment, which indicates that it may be of osmotic origin. This was confirmed by a successful attempt, presented in this paper, to alleviate the severity and duration of foal heat diarrhea with the use of a typical absorbent, kaolin clay, as a feed additive, usually applied in feed production as an anticaking agent. Based on the present results, it can be concluded that treatment of foals maintained on different stud farms with a kaolin paste reduced the duration of heat diarrhea and alleviated its severity (P < 0.05 and P = 0.001). The observed action of kaolin clay, an excellent absorbent, suggests that the so-called heat diarrhea can be caused by disturbances in the intestinal osmotic balance at this specific age of foals. The use of this preparation can reduce the risk of secondary pathological viral or bacterial diarrhea and the requirement for veterinary intervention in foal management. It can also shorten the care period and increase foal well-being, essential for the normal development of a young horse. In addition, prophylactic application of an antidiarrheal preparation based on an industrial by-product, i.e. A cheap component, will reduce the costs of foal care.

Mycoflora And Chemotype Characterization Of Fusarium Graminearum Isolatesobtained From Corn And Barley Used As Feedstuffs In The Northeast Of Iran, Abdollah Salehi, Roya Rezaeian Doloei

Turkish Journal of Veterinary & Animal Sciences

This study aimed to investigate the mycoflora and chemotyping of Fusarium graminearum isolates in corn and barley used in industrial dairy farms in Khorasan-Razavi Province, northeastern Iran. For this purpose, a total of 128 corn and barley samples were collected from 16 different large industrial dairy farms. Mean moisture of the samples collected in different seasons of the year was significantly different (P < 0.05). The most prevalent fungi isolated from corn samples were Penicillium spp. (90.62%) and Aspergillus spp. (82.81%), and that of barley samples was Penicillium spp. (89.06%). Frequency of Fusarium spp. İn corn and barley samples was 85.93% and 26.56%, respectively. All isolates (100%) were confirmed as Fusarium using an ITS primer. Eight (11.11%) out of 72 Fusarium spp. İsolates were confirmed as F. Graminearum using species-specific primers. Five out of 8 F. Graminearum isolates were positive in terms of the presence of the trichothecene-producing gene using a Tri5-specific primer. Three and 2 out of 5 toxin-producing F. Graminearum isolates were positive using Tri13DON- and Tri13NIV-specific primers, respectively. In conclusion, the presence of toxigenic Fusarium in corn and barley samples used in feedstuffs in Iran is a potential risk to animal and human health.

The activity of enzymes that digest carbohydrates at various points in the gastrointestinal tract of sheep was examined. In addition, weight and contents of digestive tract segments were examined. The experiment was performed on six adult ewes fed an 85% hay diet. The morphometric measurements revealed that the alimentary tract constituted 32% of the sheep's body mass and wet rumen contents constituted 70% of wet mass of the total digestive tract content. The protozoal population in the rumen varied from 37.2 × 104 to 54.0 × 104/mL rumen fluid. In the examined samples, ciliates were identified as belonging to the …

Appraisal Of The Impact Of Aluminosilicate Use On The Health And Performance Of Poultry, Ali Gilani, Hassan Kermanshahi, Abolghasem Golian, Saeed Seifi

Turkish Journal of Veterinary & Animal Sciences

Aluminosilicates are feed additives used for multiple purposes in the poultry industry. Bentonites, zeolites, and kaolins are types of aluminosilicate compounds that appear in the marketplace due to their capabilities as mycotoxin adsorbents and other qualifications. While there are some differences among their efficacies, anecdotal evidence confirms that these additives ameliorate aflatoxicosis and manure ammonia emission, and improve the durability of pelleted diets. Furthermore, these supplements are safe at 0.2%-1% inclusion levels in the commercial diet of broilers and layers and did not have any adverse effects on productive indices, and even promoted birds' performance. Nevertheless, their upper levels, especially …

Novel Spoxazomicins Derived From Streptomyces Sp. Rm-14−6 Attenuate Ethanol Induced Cytotoxicity In Vitro, Meredith A. Saunders

Theses and Dissertations--Psychology

An estimated 13.9% of Americans currently meet criteria for an alcohol use disorder. Ultimately, chronic alcohol use may result in neurological deficits, with up to 85% of alcoholics exhibiting signs of cognitive decline. However, biochemical and behavioral factors contributing to this decline have remained elusive. Our ongoing research program encompasses a multi-tiered screening of a natural product library and validation process to provide novel information about mechanisms underlying these deficits and to identify novel chemical scaffolds to be exploited in the development of pharmacological treatments for alcohol use disorders in a rodent organotypic hippocampal slice culture mode. Experiment 1 sought …

Loss Aversion In Cocaine Users: Influence Of Risk And Commodity Type, Justin Charles Strickland

Theses and Dissertations--Psychology

Numerous studies in behavioral economics have demonstrated that individuals are more sensitive to the prospect of a loss than a gain (i.e., loss aversion). Although loss aversion has been well described in healthy populations, little research exists in individuals with substance use disorders. The purpose of this study was to comprehensively evaluate loss aversion in cocaine users. Participants completed measures designed to assess loss aversion for drug and non-drug commodities under varying risk conditions. Cocaine demand was determined using a cocaine purchase task. Cocaine users showed a loss aversion score that was consistent across commodity and risk conditions. Compared to …

Decision-Making Processes, Driving Performance, And Acute Responses To Alcohol In Dui Offenders, Walter Roberts

Theses and Dissertations--Psychology

Alcohol-impaired driving is a major cause of motor vehicle accident and death in the United States. People who are arrested for DUI (Driving under the Influence) are at high risk to reoffend; approximately one in three of these individuals will commit another DUI offense in the three years following their first conviction (Nochajski & Stasiewicz, 2006). This high risk for recidivism in these individuals suggests that cognitive characteristics may contribute to a pattern of pathological decision making leading to impaired driving. Indeed, individuals with a history of DUI report higher rates of impulsiveness and behavioral dysregulation compared to their nonoffending …

Burnout And Depression In Psychiatric Residents, Irvin Sam Schonfeld, Eric Laurent, Pierre Vandel, Renzo Bianchi

Publications and Research

Kealy et al. (2016) found that 21% of psychiatric residents were suffering symptoms of burnout. A number of problems call that finding into question. First, the writers used a one-item measure to assess burnout. Second, mounting evidence suggests that burnout is a depressive syndrome. Third, unresolvable job stress is related to depression. Given burnout's overlap with depression and the diagnostic blur around burnout, research on the impact of job stress should connect with depression, which is nosologically well characterized and diagnosable using clinically validated instruments.

Burnout And Depression: Label-Related Stigma, Help-Seeking, And Syndrome Overlap, Renzo Bianchi, Jay Verkuilen, Romain Brisson, Irvin Sam Schonfeld, Eric Laurent

Publications and Research

We investigated whether burnout and depression differed in terms of public stigma and help-seeking attitudes and behaviors. Secondarily, we examined the overlap of burnout and depressive symptoms. A total of 1046 French schoolteachers responded to an Internet survey in November–December 2015. The survey included measures of public stigma, help-seeking attitudes and behaviors, burnout and depressive symptoms, self-rated health, neuroticism, extraversion, history of anxiety or depressive disorder, social desirability, and socio-demographic variables. The burnout label appeared to be less stigmatizing than the depression label. In either case, however, fewer than 1% of the participants exhibited …

The advancements in wearable technology, where embedded accelerometers, gyroscopes and other sensors enable the users to actively monitor their activity have made it easier for individuals to pursue a healthy lifestyle. However, most of the existing applications expect continuous commitment from the end users, who need to proactively interact with the application in order to connect with friends and attain their goals. These applications fail to engage and motivate users who have busy schedules, or are not as committed and self-motivated. In this work, we present PRO-Fit, a personalized fitness assistant application that employs machine learning and recommendation algorithms in …

The Identification Of The Direct And Indirect Pathways Through Which Leptin Facilitates Synaptic Plasticity In The Hippocampus, Catherine Van Doorn

Theses and Dissertations

Leptin, a peptide synthesized by adipocytes in the periphery, has been shown to play significant roles in feeding and energy expenditure mediated by the hypothalamus. Growing evidence supports the role of leptin in influencing synaptic plasticity in the hippocampus in that leptin dose-dependently enhances LTP, alters morphology and neurogenesis, facilitates spatial learning and memory, as well as memory retention. Models of leptin deficiency and resistance have further supported the importance of leptin in synaptic plasticity by exhibiting deficits in electrophysiological, morphological and behavioral tests that are improved after leptin restoration. The effects of leptin when applied directly into the hippocampus …

Towards Improving The Evaluation Of Speech Production Deficits In Chronic Stroke, Artemis Alexandra Basilakos

Theses and Dissertations

One of the most devastating consequences of stroke is aphasia - a disorder that impairs communication across the domains of expressive and receptive language. In addition to language difficulties, stroke survivors may struggle with disruptions in speech motor planning and/or execution processes (i.e., a motor speech disorder, MSD). The clinical management of MSDs has been challenged by debates regarding their theoretical nature and clinical manifestations. This is especially true for differentiating speech production errors that can be attributed to aphasia (i.e., phonemic paraphasias) from lower-level motor planning/programming impairments (i.e., articulation errors that occur in apraxia of speech; AOS). Therefore, the …

Neural And Behavioral Correlates Of Planning During Vocal Motor Control, Stacey Jean Sangtian

Theses and Dissertations

Speech is a goal-directed movement developed to serve the purpose of human communication. During speech, the brain simultaneously coordinates complex motor behavior and sensory information for planning, execution and online monitoring for error correction in order to ensure accurate delivery of the vocal messages. Models of speech production and voice motor control have adapted the principles of the internal forward model to explain that speech sound production is controlled by comparison of internal predictions with sensory feedback. Growing evidence from studies conducted in speech and limb motor movement indicate that these sensory predictions and responsive commands are loaded in anticipation …

Depression Among Pregnant Latinas In South Carolina, Andrew Fogner

Theses and Dissertations

The aim of the study was to determine the prevalence of depression among pregnant Latinas. To bring to light the importance of prenatal depression prevention, we assessed the effect of the quality of healthcare providers among South Carolina Latinas (n=171). Women answered a validated CES-D and were categorized as depressed (score >16). In multivariate analyses, good perception of quality of healthcare was more likely among women who were not depressed; adjusted odds ratio of 0.75, 95% confidence interval 0.37 – 1.55. The findings show the need for tailoring healthcare to Latinas with prenatal depression prevention. It is imperative to understand …

The Influence Of Fine Particulate Matter On Inflammatory Bowel Disease In South Carolina: An Ecological Analysis, Joshua Eric Sellner

In recent years, both conditions have become much more prevalent and recognized as major public health issues. Environmental factors have become the focus of recent research around the cause of these diseases. Although shown to have detrimental effects on diseases similar to that of the Inflammatory Bowel Diseases, fine particulate matter’s role in these diseases has not been adequately investigated.

Aim. The purpose of this study was to test the relation of fine particulate matter with hospitalizations attributable to …

A Qualitative Study Of How Communities Think About And Act Upon Hunger In The Presence Of A Food Banking System, Eliza Miriam Fishbein

Theses and Dissertations

Hunger is often addressed by providing food directly to those experiencing symptoms of food insecurity and hunger. Even with the availability of government food assistance programs, food insecurity and hunger rates continue to rise. Many local community organizations (e.g., small food banks, faith-based organizations, schools) across the country have come together to create and implement a variety of nongovernment food programs. Although there is no evidence these programs lower food insecurity and hunger rates, community organizations appear to be strongly committed to sustaining these programs. Little is known about the basis for this commitment, i.e., “ the will to act …

Implementation Processes And Impacts Of School Store Policies In South Korea, Seul Ki Choi

Theses and Dissertations

With the concern of unhealthy school food environments, the South Korean government enacted two school nutrition policies to reduce unhealthy foods in school stores. The first policy banned on soft drinks sales in school stores enacted in 2007. The second policy restricted energy-dense nutrient-poor (EDNP) food sales in school stores enacted in 2009. This study aims to examine the changes in adolescents’ food intake and foods sold in school stores due to the two policies and to understand the policy implementation processes.

The Korea National Health and Nutrition Examination Surveys were used to examine trends in adolescents’ energy intake from …
