Comparison Of Sevoflurane And Isoflurane Effects On Cardiovascular Andrespiratory System During Spontaneous Ventilation In Angora Goats, Ali̇ Kumandaş, Ertuğrul Elma

Turkish Journal of Veterinary & Animal Sciences

Seven healthy Angora goats were used to compare the effects of isoflurane and sevoflurane on the cardiovascular and respiratory systems during anesthesia periods. Once anesthesia was induced with propofol at 5.1 ± 0.9 mg/kg, it was maintained with isoflurane at 1%-3% in the first treatment period and sevoflurane at 2%-4% in the second treatment period after a 15-day interval. Heart rates measured immediately after anesthesia induction and 5 min later were found to be statistically significant between anesthetic groups (P < 0.05). Mean blood pressure in the isoflurane group decreased (75.7 ± 7.2 to 59.8 ± 9.8 mmHg) (P < 0.05) throughout the anesthesia period. It was determined that respiratory rate in sevoflurane treatment was lower than that in isoflurane treatment. In terms of time to stand up, sevoflurane-administered animals recovered significantly faster than animals intubated with isoflurane anesthesia (13.1 ± 4.4 and 25.0 ± 8.6 min) (P < 0.05). According to cardiopulmonary values, the respiratory rate was lower in the sevoflurane-applied animals compared to that of those receiving isoflurane anesthesia, although the difference was not statistically significant, and hypercapnia were not observed in either group. Consequently, it was determined that in the Angora goat, propofol-sevoflurane anesthesia exerts lower pressure on the cardiovascular system than isoflurane anesthesia. At the same time, recovery from sevoflurane anesthesia was shorter, and therefore it can be preferred to other anesthesia agents for routine anesthesia.

Polymorphisms Of Ovine Prion Protein (Prp) Gene In Pramenka Sheepbreed Population In Bosnia And Herzegovina, Ervin Zecevic, Admir Dokso, Amra Kazic, Muhamed Brka

Turkish Journal of Veterinary & Animal Sciences

Transmissible spongiform encephalopathies (TSEs) are a group of diseases that affect the nervous system and lead to death. The putative infectious agent is the host-encoded prion protein (PrP) and it appears that the development of scrapie in sheep is closely related to polymorphisms in the host PrP gene. The aim of this study was to investigate three well-known polymorphisms in exon 3 of the PrP gene (at codons 136, 154, and 171) that have a clear and significant effect on scrapie in sheep. Four other polymorphisms (at codons 145, 185, 231, and 237) that are yet undefined were also investigated. …

Analysis Of Acid?Base Disorders In Calves With Lactic Acidosis Using Aclassic Model And Strong Ion Approach, Michal Bednarski, Robert Kupczynski

Turkish Journal of Veterinary & Animal Sciences

The objective of this study was to analyze the disorders of acid-base balance in calves with lactic acidosis using the classic model and the strong ion approach. The study included 40 calves: group I was the control group (n = 20) and group II consisted of calves with diarrhea and lactic acidosis (n = 20). The highest lactate concentration (5.49 ± 2.58 mmol/L) was documented in diarrheic calves. The diarrheic calves presented with significantly lower pH, pCO2, and concentrations of HCO3- (P < 0.01), and with higher anion gap (AG), strong ion difference (SID3, SID7), and strong ion gap (SIG) (P < 0.01) than the controls. In the group of diarrheic calves lactic acid correlated with AG (r = 0.684, P < 0.01), SID3 (r = 0.718, P < 0.01), SID7 (r = 0.494, P = 0.03), and SIG (r = 0.561, P = 0.01). There was a negative correlation between lactate and effective SID (SIDEff) (r = -0.499, P = 0.02), and total plasma concentration of nonvolatile buffers (ATot ) (r = -0.361, P = 0.04). The results indicated that in lactic acidosis there were specific disturbances with an increased concentration of unmeasured strong ions.

Evaluation Of The Genetic Resistance Status To Classical And Atypicalscrapie In Karacabey Merino Rams, Yalçin Yaman, Mehmet İhsan Soysal, Cemal Ün

Turkish Journal of Veterinary & Animal Sciences

Scrapie, the oldest prion disease of sheep, has two types: classical and atypical scrapie. It was determined that some nucleotide polymorphisms in the PrP coding gene have affected classical and atypical scrapie susceptibility. Consequently, EU member states have established breeding programs aiming to increase genetic resistance of their flocks to classical scrapie. These breeding programs have primarily been implemented in economically important breeds. Thus, we investigated classical and atypical scrapie related PrP genotypes of the Karacabey merino breed, which is of great economic importance in western regions of Turkey. In relation to classical scrapie, three alleles (ARR, ARQ, and VRQ) …

Hitchhiking Bats On The Great Lakes Of North America, Saska E.H. Lohi

Dissertations, Master's Theses and Master's Reports

Bats can act as potential vectors for various zoonotic diseases and other pathogens. Therefore their interactions with people should be examined to mitigate potential risks. Bats are small flying mammals and hide in small crevices during daylight hours, making them difficult to observe. Consequently, they have a capacity to “hitchhike” on ships to be dispersed over large distances.

This study focused on anthropogenic unintentional bat translocations, i.e. hitchhiking bats. The study area is the Great Lakes region in North America. Using a web-based questionnaire survey, I asked the public about the frequency of bat-human encounters on ships, their nature, and …

Climatic Preferences And Distribution Of 6 Evolutionary Lineages Oftyphlops Vermicularis Merrem, 1820 In Turkey Using Ecological Niche Modeling, Serkan Gül, Yusuf Kumlutaş, Çeti̇n Ilgaz

Turkish Journal of Zoology

According to evolutionary biologists, ecology is a very important factor in speciation. Ecology may be effective at driving adaptive divergence between lineages in different environments and climatic conditions. Because Anatolia has major mountain belts, paleogeographic characteristics, and unique climatic traits, it plays an important role in speciation and shows a barrier effect for many terrestrial species. In this study, we investigated the climatic preferences of 6 isolated evolutionary lineages of Typhlops vermicularis in Anatolia using ecological niche modeling. Our results revealed that both glacial (Last Glacial Maximum) and interglacial (Last Interglacial) modeling, as well as current modeling, showed the most …
