Faecal Carriage Of Listeria Monocytogenes In Stray Dogs In Bursa Province, Turkey, A. Levent Kocabiyik, Cengi̇z Çeti̇n, Cüneyt Özakin

Turkish Journal of Veterinary & Animal Sciences

The faecal carriage rate of Listeria monocytogenes in stray dogs in Bursa province, Turkey, was determined from 82 faecal samples by bacteriological methods. L. monocytogenes was isolated from only one (1.22%) of the samples examined. The isolate was serotyped as 1/2b. It was concluded that stray dogs could be a reservoir of the organism as well as a source of human listeriosis in Turkey. This is the first report on the isolation of L. monocytogenes from a dog in this country.

Accumulation Of Retinol In The Liver After Prolonged Hyporetinolemia In The Vitamin A-Sufficient Rat, Sin Gieng, Jens Raila, Francisco Rosales

Faculty Publications

We assessed the effects of prolonged reduction of plasma retinol concentrations (hyporetinolemia) on the distribution of tissue vitamin A (VA) and of its active compounds using a model of continuous recombinant human interleukin-6 (rhIL-6) infusion via osmotic minipumps in VA-sufficient male rats. Plasma retinol and retinol-binding protein (RBP) concentrations remained decreased and lower in rhIL-6-treated rats compared with controls from 7.5 h throughout 7 days of infusion (P < 0.001). This reduction was accompanied by a 68% increase in hepatic retinol concentration by 7 days (P < 0.05). Hepatic and renal retinyl palmitate and retinoic acid concentrations did not change, and renal megalin content remained unchanged; hepatic RBP concentrations were 41% lower in rhIL-6-treated rats compared with controls (P < 0.05). These results indicate that instead of being lost, retinol accumulated in the liver during inflammation and that hyporetinolemia was attributable to a decrease in the availability of hepatic RBP. A plausible consequence of the effect of rhIL-6-induced hyporetinolemia is that by 7 days tissues that are dependent on plasma retinol may become deprived of VA.These results have important implications in understanding the mechanism by which measles infection induces hyporetinolemia and VA deficiency of extrahepatic tissues.

Vaccine-Associated Feline Sarcoma (Vafs) With Multiple Recurrences In A Turkish Van Cat, Yilmaz Aydin, Babür Bi̇li̇r

Turkish Journal of Veterinary & Animal Sciences

Vaccine-associated feline sarcoma (VAFS) with multiple recurrences was diagnosed in the specimens at the injection site of a Turkish Van cat that had been vaccinated four months previously. The original tumor consisted of two compartments each 2.5 cm and 3.5 cm in diameter. It recurred five times following surgery and local recurrences necessitated five more radical resections within two years. Euthanasia was performed when pleural effusion developed, but evidence of metastatic disease was not observed. This article reports the first case of a vaccine-associated feline sarcoma in a Turkish Van cat clinically diagnosed as prominent evidence of postvaccinal sarcoma from …

The Evidence For A Nascent Biotechnology Cluster In Cork, John W. Hobbs

Theses

Over the past 30 years, encouraged by Ireland’s low rate of corporation tax (currently 12.5 %), and active promotion of FDI by the IDA, foreign owned pharmaceutical plants have set up and multiplied in the Cork area. To Ireland’s advantages of a low tax rate, an English speaking population, a pro-business environment and membership of EU, Cork offered the added attractions of a deepwater port and large natural harbour, good freight connections, an international airport, an educated workforce and excellent sporting and leisure facilities for sailing, golf, etc. (Pfizer, Eli Lilly, Novartis, GlaxoSmithKline, Johnson & Johnson and Schering Plough have …

Development, Evaluation And Characterization Of Protein-Isoflavone Enriched Soymilk, Janette Ethel-Pessi Saidu

LSU Doctoral Dissertations

Adequate provision of soy isoflavone and protein in soybean products is essential in meeting the soy health claim and the promotion of a healthy product. Commercial soymilks contain inadequate amounts of protein and isoflavone to meet the FDA recommended 25g and 40-50mg/day level, respectively, in 1-2 servings. This research study set out to investigate the possibility of producing a protein-isoflavone enriched (PIE) soymilk by incorporating soy germ in soymilk to provide the recommended FDA level in 1-2 servings. Three PIE soymilks containing 25 (SG25), 30 (SG30), and 35% (SG35) germ were prepared and compared to 100% whole soybean milk (WSB-control) …

Regulation Of Glucose Metabolism In Dairy Cattle, Christie Cheatham Stanley

LSU Doctoral Dissertations

The experiments described herein are designed to elucidate many metabolic changes that occur to regulate the partitioning of nutrients between production and animal maintenance with particular regard to glucose metabolism and insulin sensitivity. The onset of milk production and parturition causes dramatic stress to the cow. The challenge of improving metabolism during this period is being addressed by nutritional management with the possibility of the addition of supplements. The use of Ca-propionate as a supplement did not affect glucose metabolism in transition cows. The data revealed that insulin sensitivity was low during the transition period, but the tissue responses to …

Predicting Student Performance In A Statistics Course Using The Mathematics And Statistics Perception Scale (Mpsp), Isabelle D. Cherney, Ramie R. Cooney

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Students tend to have higher apprehension for a statistics class than for other psychology classes. Because anxiety can impair the performance in a class, and ultimately the mastery of the subject matter, the Mathematics and Statistic Perception Scale (MSPS) was designed to assess students' perceptions of anxiety and attitudes toward statistics as well as provide a tool that could be used in classroom settings. The 22-item scale with three subscales (mathematics perceptions, statistics perceptions, and perceptions of relevance) was administered to 154 undergraduates and showed that over the course of a semester, perceptions of mathematics anxiety tended to decrease and …

The Unionid Mussels (Mollusca: Bivalvia: Unionidae) Of The Big Blue River Basin Of Northeastern Kansas And Southeastern Nebraska, Ellet Hoke

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

A survey of 96 locales in the Big Blue River and its minor tributaries supplemented by museum vouchers documented the presence or former presence of 25 native unionid mollusk species and one introduced bivalve. Including the previously reported Little Blue Basin, the total documented unionid inventory ofthe Big Blue Basin consists of twenty-six species. Over a third of these species may have been extirpated from the basin, and many of the surviving species appear to have experienced significant range reductions. Habitat in the region is adversely impacted by surface and subsurface water withdrawals, erosion/siltation, and grazing. Chemicals and other pollutants …

The Degree Of Chlmpanzee Theory Of Mind And The Evolution Of Modularity, Benjamin Grant Purzycki

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Whether or not chimpanzees have the ability to mentally represent others' mental states or theory of mind (ToM) has yet to be definitively established. This results from three problems. First, modular theory of mind accounts lead researchers to adopt an either/or approach to psychological faculties which obfuscates both within- and across-species variability. Second, present research continues to rely on the continued trend to polarize nature and nurture. Third, the bulk of the work compares humans with chimpanzees rather than looking at the entire range of primate species. I propose "degree approach" by way of the Integrated Causal Model which particularizes …

Trehalose Loading Through The Mitochondrial Permeability Transition Pore Enhances Desiccation Tolerance In Rat Liver Mitochondria., Xiang-Hong Liu, Alptekin Aksan, Michael Menze, Steven Hand, Mehmet Toner

Faculty and Staff Scholarship

Trehalose has extensively been used to improve the desiccation tolerance of mammalian cells. To test whether trehalose improves desiccation tolerance of mammalian mitochondria, we introduced trehalose into the matrix of isolated rat liver mitochondria by reversibly permeabilizing the inner membrane using the mitochondrial permeability transition pore (MPTP). Measurement of the trehalose concentration inside mitochondria using high perfOrmance liquid chromatography showed that the sugar permeated rapidly into the matrix upon opening the MPTP. The concentration of intra matrix trehalose reached 0.29 mmoVmg protein (-190 mM) in 5 min. Mitochondria, with and without trehalose loaded into the matrix, were desiccated in a …

Allosteric Models For Multimeric Proteins : Oxygen-Linked Effector Binding In Hemocyanin., Michael Menze, Nadja Hellman, Heinz Decker, Manfred Grieshaber

Faculty and Staff Scholarship

In many crustaceans, changing concentrations of several low molecular weight compounds modulates hemocyanin oxygen binding, resulting in lower or higher oxygen affinities of the pigment. The nonphysiological effector caffeine and the physiological modulator urate, the latter accumulating in the hemolymph of the lobster Homarus Vulgaris during hypoxia, increase hemocyanin oxygen affinity and decrease cooperativity of oxygen binding. To derive a model that describes the mechanism of allosteric interaction between hemocyanin and oxygen in the presence of urate or caffeine, studies of oxygen, urate, and caffeine binding to hemocyanin were performed. Exposure of lobster hemocyanin to various pH values between 7.25 …

Cryopreservation Of Human Hematopoietic Stem And Progenitor Cells Loaded With Trehalose : Transient Permeabilization Via The Adenosine Triphosphate-Dependent P2z Receptor Channel., Sandhya S. Buchanan, Michael A. Menze, Steven C. Hand, David W. Pyatt, John F. Carpenter

Faculty and Staff Scholarship

Hematopoietic stem and progenitor cells (HPCs) are a heterogenic population of cells used to treat a number of human diseases. Multilineage differentiation is a required function in successful hematopoietic reconstitution after transplantation of cryopreserved grafts. Conventional use of the cryoprotectant dimethyl sulfoxide (DMSO) has resulted in some reports of infusion related toxicity attributed to DMSO and/or damage to cells during freezethawing procedures. The purpose of this study was to explore the use of trehalose, a nontoxic disaccharide of glucose, as an alternative cryoprotectant. Trehalose was introduced into HPCs using the P2Z receptor, known to form nonselective pores in the presence …

The Challenge Of Environmental Protection, Jennifer Mattei

Biology Faculty Publications

Connecticut is in the midst of a demographic transition to a period of lower population growth. These demographic changes will help check the pressures exerted on the state's natural resources by population growth. Water, air, soil, energy sources, food, fisheries, forests, and biodiversity are common pool resources upon which we depend in ways that transcend political boundaries. Those governing Connecticut should help turn the state into a model of how to manage natural resources by halting forest fragmentation, reducing pollution, and promoting environmental science education.

Effect Of Dietary Fatty Acid Composition On Depot Fat And Exercise Performance In A Migrating Songbird, The Red-Eyed Vireo, Barbara J. Pierce, Scott R. Mcwilliams, Timothy P. O'Connor, Allen R. Place, Christopher G. Guglielmo

Biology Faculty Publications

Most migrating birds accumulate lipid stores as their primary source of energy for fueling long distance flights. Lipid stores of birds during migration are composed of mostly unsaturated fatty acids; whether such a fatty acid composition enhances exercise performance of birds is unknown. We tested this hypothesis by measuring metabolic rate at rest and during intense exercise in two groups of red-eyed vireos, a long-distance migratory passerine, fed either a diet containing 82% unsaturated fat (82%U), or one containing 58% unsaturated fat (58%U). Vireos fed the 82%U diet had fat stores containing (77%) unsaturated fatty acids, whereas vireos fed the …
