Fas Ligand Expression In The Porcine Oviduct, Paisan Tienthai, Yumi Hoshino Mar 2005

Fas Ligand Expression In The Porcine Oviduct, Paisan Tienthai, Yumi Hoshino

The Thai Journal of Veterinary Medicine

The expression of Fas/Fas Ligand (FasL) is thought to be involved in the immune privileged status of the testis, cornea and the placenta. The objective of this study was to see whether FasL mRNA was expressed in the epithelium of the porcine oviduct, where spermatozoa, oocytes and developing embryos avoid elimination by the female immune system during the estrous cycle. The distribution of Fas/FasL might provide information about immune privileged sites in the pig oviduct. The gene expression of FasL was detected in the uterotubal junction (UTJ), isthmus and ampulla of the pig oviductal epithelium, during both pre- and post-ovulatory …

5-Ht1b Receptor-Mediated Presynaptic Inhibition Of Gaba Release In The Suprachiasmatic Nucleus, Jayne R. Bramley, Patricia J. Sollars, Gary E. Pickard, F. Edward Dudek Feb 2005

5-Ht1b Receptor-Mediated Presynaptic Inhibition Of Gaba Release In The Suprachiasmatic Nucleus, Jayne R. Bramley, Patricia J. Sollars, Gary E. Pickard, F. Edward Dudek

School of Veterinary and Biomedical Sciences: Faculty Publications

The suprachiasmatic nucleus (SCN) receives a dense serotonergic innervation that modulates photic input to the SCN via serotonin 1B (5-HT1B) presynaptic receptors on retinal glutamatergic terminals. However, the majority of 5-HT1B binding sites in the SCN are located on nonretinal terminals and most axonal terminals in the SCN are GABAergic. We therefore tested the hypothesis that 5-HT1B receptors might also be located on SCN GABAergic terminals by examining the effects of the highly selective 5-HT1B receptor agonist CP-93,129 on SCN miniature inhibitory postsynaptic currents (mIPSCs). Whole cell patch-clamp recordings of mIPSCs were obtained from rat …

Zoonotics and Wildlife Disease: Publications

Scrapie is one of several transmissible spongiform encephalopathies of livestock. Disease susceptibility is linked to polymorphisms in the normal prion protein gene that encodes the mammalian prion precursor. Codon 171 of this gene is a major determinant of scrapie susceptibility. Selection for arginine (R) at codon 171 is encouraged by the USDA to decrease the incidence of scrapie. Objectives of this study were to determine the frequency of R allele variants at codon 171 in a sample of sheep from five breeds (Columbia, Hampshire, Rambouillet, Suffolk, and Targhee) and western white-faced commercial ewes and to determine whether the R allele …

Jenny, Katherine I. O'Rourke, Ermais D. Belay, Lawrence B. Schonberger, Robert B. Pertersen, Man-Sun Sy, Shu G. Chen, Pierluigi Gambetti

Zoonotics and Wildlife Disease: Publications

Chronic wasting disease (CWD), a prion disease affecting free-ranging and captive cervids (deer and elk), is widespread in the United States and parts of Canada. The large cervid population, the popularity of venison consumption, and the apparent spread of the CWD epidemic are likely resulting in increased human exposure to CWD in the United States. Whether CWDis transmissible to humans, as has been shown for bovine spongiform encephalopathy (the prion disease of cattle), is unknown. We generated transgenic mice expressing the elk or human prion protein (PrP) in a PrP-null background. After intracerebral inoculation with elk CWD prion, two lines …

Predictive Spatial Dynamics And Strategic Planning For Raccoon Rabies Emergence In Ohio, James E. Childs, David L. Smith, Colin A. Russell, Leslie A. Real Jan 2005

Predictive Spatial Dynamics And Strategic Planning For Raccoon Rabies Emergence In Ohio, James E. Childs, David L. Smith, Colin A. Russell, Leslie A. Real

Zoonotics and Wildlife Disease: Publications

Rabies is an important public health concern in North America because of recent epidemics of a rabies virus variant associated with raccoons. The costs associated with surveillance, diagnostic testing, and post-exposure treatment of humans exposed to rabies have fostered coordinated efforts to control rabies spread by distributing an oral rabies vaccine to wild raccoons. Authorities have tried to contain westward expansion of the epidemic front of raccoonassociated rabies via a vaccine corridor established in counties of eastern Ohio, western Pennsylvania, and West Virginia. Although sporadic cases of rabies have been identified in Ohio since oral rabies vaccine distribution in 1998, …

Spatial Management Of Wildlife Disease, Richard Horan, Christopher Wolf, Eli P. Fenichel, Kenneth H. Mathews, Jr. Jan 2005

Spatial Management Of Wildlife Disease, Richard Horan, Christopher Wolf, Eli P. Fenichel, Kenneth H. Mathews, Jr.

Michigan Bovine Tuberculosis Bibliography and Database

The spread of wildlife diseases is a major threat to livestock, human health, resource-based recreation, and biodiversity conservation (Cleaveland, Laurenson, and Taylor). The development of economically sound wildlife disease-management strategies requires an understanding of the links between ecological functions (e.g., disease transmission and wildlife dispersal) and economic choices, and the associated tradeoffs. Spatial linkages are particularly relevant. Yet while ecologists have long-argued that space is important (Hudson et al.), prior economic work has largely ignored spatial issues.

For instance, Horan and Wolf analyzed a case study of bovine tuberculosis (bTB) in Michigan deer, a problem where the disease appears to …

Relationships Between Milk Yield And Udder Measurements In Brown Swiss Cows, Muammer Ti̇lki̇, Şeref İnal, Mehmet Çolak, Mustafa Gari̇p

Turkish Journal of Veterinary & Animal Sciences

The effects of udder and teat measurements on milk yield in Brown Swiss Cows were studied. The differences among the means for front and rear teat length, front and rear teat diameter, front and rear udder height, distance between front teats and mammary type scores in different lactation numbers were statistically significant (P < 0.001). Front and rear teat length, and front and rear udder height after milking were higher than before milking. Front and rear teat diameter, distance between front teats, distance between rear teats and distance between front and rear teats after milking were lower than before milking. Furthermore, 305-day milk yield and milk yield per milking were significantly positively correlated with distance between front and rear teats and mammary type scores before milking (P < 0.001). The mean values before milking for front and rear teat length, front and rear teat diameter, front and rear teat udder height, distance between front teats, distance between rear teats, distance between front and rear teats and mammary type scores at general lactation were 59.45 and 49.72 mm, 22.14 and 21.53 mm, 47.96 and 47.59 cm, 12.29 cm, 7.76 cm, 9.58 cm and 23.65, respectively. In conclusion, teat and udder measurements and mammary type scores significantly affected milk yield.

The Effect Of Mad Cow (Bse) Scare On Beef Demand And Sales Loss: The Case Of İzmir, Bülent Mi̇ran, Sedef Akgüngör Jan 2005

The Effect Of Mad Cow (Bse) Scare On Beef Demand And Sales Loss: The Case Of İzmir, Bülent Mi̇ran, Sedef Akgüngör

Turkish Journal of Veterinary & Animal Sciences

This paper investigates the effect of the BSE scare on beef consumption due to the intense media coverage. Using monthly data, a beef demand model for January 1995-February 1997 period is estimated for İzmir Province. Beef sales dropped immediately after the media coverage on BSE in April 1996 and continued through June 1996 when the intense media coverage stopped. The econometric model reveals that beef sales in İzmir would have been 36.4% higher if the BSE crisis never occurred. The annual individual willingness to pay is $0.5224 per year to avoid consuming BSE contaminated meat.

Evaluation Of The Photocopy Method For Counting Puntius Conchonius’S Eggs, Şehri̇ban Çek, Mahmut Ali̇ Gökçe

Turkish Journal of Veterinary & Animal Sciences

The photocopy technique was developed to count fish eggs. Fecundity of the rosy barb Puntius conchonius was determined by both actual counts and the photocopy method. Egg stripping and fertilisation were performed manually. After fertilisation, water-hardened eggs were photocopied. White circles were counted and recorded as viable eggs and dark dots counted as dead eggs. Egg numbers estimated by this technique were significantly correlated with those estimated by actual counting (r = 0.999; P < 0.05). The advantage of the photocopy method is that it is a relatively fast method without significant loss in accuracy and it is cheaper than the other currently used methods.
