Leaders Of The Pack: Women And The Future Of Veterinary Medicine, Julie Kumble, Donald F. Smith

Purdue University Press Book Previews

Veterinary medicine has undergone sweeping changes in the last few decades. Women now account for 55 percent of the active veterinarians in the field, and nearly 80 percent of veterinary students are women. However, average salaries have dropped as this shift has occurred, and even with women in the vast majority, only 25 percent of leadership roles are held by women.

These trends point to gender-based inequality that veterinary medicine, a profession that tilts so heavily toward women, is struggling to address. How will the profession respond? What will this mean for our students and schools? What will it mean …

Effects Of Temperature And Diet In Stable Fly (Diptera: Muscidae) Development, Melina Florez-Cuadros

Department of Entomology: Dissertations, Theses, and Student Research

Stable flies are among the most important blood feeding ectoparasites of cattle worldwide. The livestock industry is losing more than $2 billion dollar annually in the United States alone. Moist decaying vegetative material with bacteria supports larval development. Temperature and diet quality are important factors for stable fly development, affecting development rates, adult survival, and size, but how temperature affects adult size and interacts with nutrition is unknown. This study characterizes the relationship of temperature and diet quality in the development of stable flies. Two statistical models were used to analyze the effect of temperature alone (Lysyk, 1998) and temperature-diet …

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. …

The Thai Journal of Veterinary Medicine

Bovine endometritis is one of the most common reproductive diseases and causes important economic losses. Lipopolysaccharide (LPS) from Gram-negative bacteria is recognized by Toll-like receptor 4 (TLR4). Binding of LPS and TLR4 mediates the expression of proinflammatory cytokines and chemokines. This study aimed to access the effect of TLR4 antagonist (RsLPS) on the immune responses of bovine endometrial cells. Primary culture of bovine endometrial cells were challenged with LPS (100 ng/ml) after treated with and without RsLPS (5000 ng/ml). Endometrial cells without RsLPS and LPS treatment served as control. The mRNA expression of TLR4, CD14, TNF, IL1B and IL8 were …

Elephant endotheliotropic herpesviruses (EEHVs) can cause fatal hemorrhagic disease in elephants, especially young captive Asian elephants (Elephas maximus). Currently, seven EEHV types have been reported. In this study, EEHVs were examined in whole-blood samples derived from 56 captive Asian elephants from eight provinces in Thailand by nested PCR using primers specific to the viral DNA polymerase gene in an attempt to monitor EEHV elephant cases. After EEHV testing, one sample (1.78%) was positive and found to be closely related to EEHV4 with 99% amino acid identity. This sample was from a three-year-old female Asian elephant with no clinical signs. These …

Reproductive Control In Elephant: A Tool For Population And Aggression Management, Chaleamchat Somgird, Janine L. Brown, Chatchote Thitaram

The Thai Journal of Veterinary Medicine

Although Asian elephant is listed among the endangered species, the number of populations is over the carrying capacity in some areas, resulting in human-elephant conflict, as well as African elephants. High aggression associated with musth and female reproductive pathology are observed in captive elephants. Thus, population and aggression management through reproductive control is an alternative method for mitigating these problems. This article reviews methods of reproductive control in both Asian and African elephants with an overview of male and female reproductive physiology. Hormonal control and immunocontraception, i.e. porcine zona pellucida and gonadotropin releasing hormone (GnRH), are described for the control …

Antiviral Activity Of Thymus Vulgaris And Nepeta Cataria Hydrosols Against Porcine Reproductive And Respiratory Syndrome Virus, Kraijak Kaewprom, Yu-Hsin Chen, Chuen-Fu Lin, Ming-Tang Chiou, Chao-Nan Lin

The Thai Journal of Veterinary Medicine

Porcine reproductive and respiratory syndrome (PRRS) is characterized by reproductive failure of sows and respiratory problems of nursery and growing pigs. Current management strategies mainly focus on preventing PRRS virus (PRRSV) infection through vaccination. However, the currently available modified live vaccines are not sufficient to eradicate the virus and do not provide complete immunity from infection. In search of agents that may be proven clinically effective against North American PRRSV (NA-PRRSV or US-PRRSV) infection, 42 natural herb hydrosols were purified and subjected to screening of their antiviral activity against two US-PRRSV strains in MARC-145 cells. Based on results obtained from …
