Effects Of Streptozotocin-Induced Diabetes On Gene And Protein Expression In Sinoatrial Node Of Rat Heart, Zannatul Ferdous May 2016

Effects Of Streptozotocin-Induced Diabetes On Gene And Protein Expression In Sinoatrial Node Of Rat Heart, Zannatul Ferdous

Theses

Diabetes mellitus is one of the most common endocrine disorders and its global prevalence is increasing at an alarming rate. Cardiovascular disease is the major cause of morbidity and mortality among diabetic patients. In addition to defects in contraction, the diabetic heart also frequently suffers from disturbances to the electrical conduction system. This study investigates the effects of diabetes on the sinoatrial node (SAN) of the rat heart. Previous in vivo and in vitro experiments have demonstrated reduced heart rate, longer SAN action potential duration, prolonged pacemaker cycle length and Sino-atrial conduction time in streptozotocin (STZ) - induced diabetic rat …


Evaluation Of Reproductive Strategies In Captive California Yellowtail (Seriola Dorsalis) Using Genetic Parentage Analyses, Elizabeth K. Smith, Mark Drawbridge Ms, John Hyde Phd, Geoffrey Morse Phd Sep 2015

Evaluation Of Reproductive Strategies In Captive California Yellowtail (Seriola Dorsalis) Using Genetic Parentage Analyses, Elizabeth K. Smith, Mark Drawbridge Ms, John Hyde Phd, Geoffrey Morse Phd

Theses

A good understanding of spawning dynamics of species in aquaculture is vital in order to maximize egg production and quality as well as efficient allocation of food and space resources. The breeding program of California yellowtail (CYT; Seriola dorsalis previously Seriola lalandi) at Hubbs-SeaWorld Research Institute (HSWRI) is set up such that up to 30 wild caught brood fish can broadcast spawn in a group setting, just as CYT reproduce in the wild. The population of brood fish were originally caught offshore from Southern California, and are maintained under ambient sea water and natural lighting conditions. The spawning season …


Identification And Characterization Of Equine Rotaviruses In Southern Ireland, Crystal Cronin Jan 2011

Identification And Characterization Of Equine Rotaviruses In Southern Ireland, Crystal Cronin

Theses

Group A Rotaviruses(GARVs) are enteric pathogens which induce acute gastroenteritis in infants, neonates and the young of many animal species. During a 4 year study (2005-2009), 64 fecal samples from symptomatic foals, from several counties, in the south of Ireland, were molecularly characterized to determine the VP& (G type), VP4 (P type), and NSP4 antigenic specificities. Globally, G3 [P12] and G14[P12] are recognized as the predominant equine GARV strains. Twenty-two samples (34.38%) were found to contain G3 viruses, while 21 samples (32.81%) contained G14 viruses. In this study, there was a distinct increase in the incidence of mixed infections circulating …


Molecular Epidemiology Of Antibiotic Resistant Salmonella Enterica Strains From Different Animal And Human Sources In Ireland, David George Lee Jan 2006

Molecular Epidemiology Of Antibiotic Resistant Salmonella Enterica Strains From Different Animal And Human Sources In Ireland, David George Lee

Theses

In this study, 176 isolates of Salmonella were collected from different laboratories in Ireland. All isolates were confirmed to be of the genus Salmonella by performing bacteriological and biochemical tests. Briefly, all isolates were cultured onto XLD agar after which pure cultures were verified and stocked at this institute. Definitive identification was carried out using the API 20-E system and a separate urease test was also performed on all isolates. After confirmation of the genus, all isolates were prepared for antibiotic susceptibility testing and r-types were determined using sixteen antibiotics. Depending on the antibiotic resistance profiles, isolates were selected for …
