Use Of Gis To Evaluate Livestock-Wildlife Interactions Relative To Tuberculosis Spread On Molokai Island, Hawaii, Stephanie Bany, Jerome Freier Jan 2000

Use Of Gis To Evaluate Livestock-Wildlife Interactions Relative To Tuberculosis Spread On Molokai Island, Hawaii, Stephanie Bany, Jerome Freier

Michigan Bovine Tuberculosis Bibliography and Database

Historically, bovine tuberculosis has occurred and been eradicated several times on the Hawaiian island of Molokai. After the most recent depopulation of cattle, TB was again identified in an adult cow in 1997, thus continuing the investigation into why bovine tuberculosis is reoccurring on the island. The Centers for Epidemiology and Animal Health (CEAH) have implemented spatial analysis using ArcView software that, along with epidemiological investigations, attempts to identify the environmental factors responsible for maintaining this disease in natural foci. To examine the ecological aspects of tuberculosis transmission from wildlife to livestock, and to identify the foci of infection, we …

Quantitative Image Analysis Of Simian Immunodeficiency Virus Replication In Macrophages Coinfected With Mycobacterium Avium Complex, Qingsheng Li, Keith G. Mansfield, Andrew Lackner, Ashley T. Haase

Qingsheng Li Publications

Mycobacterium avium is the most frequent cause of disseminated bacterial infection in patients with human immunodeficiency virus type 1 infection and in rhesus macaques with simian immunodeficiency virus (SIV) infection. This animal model of AIDS was used to test the hypothesis that this frequent association is the result of reciprocal enhancement of replication of both microorganisms. The replication of M. avium and SIV was analyzed in lymphatic tissues obtained from rhesus macaques experimentally inoculated with SIVmac who developed or remained free of overt M. avium infection. In situ hybridization, quantitative image analysis, and staining of M. avium and of macrophages …

Remifentanil (4-methoxycarbonyl-4-[(1-oxopropyl)phyenylamino]-1- piperidinepropionic acid methyl ester) is a μ-opioid receptor agonist with considerable abuse potential in racing horses. The identification of its major equine urinary metabolite, 4-methoxycarbonyl-4-[(1- oxopropyl)phenylamino]-1-piperidinepropionic acid, an ester hydrolysis product of remifentanil is reported. Administration of remifentanil HCl (5 mg, intravenous) produced clear-cut locomotor responses, establishing the clinical efficacy of this dose. ELISA analysis of postadministration urine samples readily detected fentanyl equivalents in these samples. Mass spectrometric analysis, using solid-phase extraction and trimethylsilyl (TMS) derivatization, showed the urine samples contained parent remifentanil in low concentrations, peaking at 1 h. More significantly, a major peak was identified as …

The tests evaluated were routine histopathology, acid-fast staining, detection of acid-fast bacilli in culture, and an M. tuberculosis group-specific genetic probe applied to pure cultures. Each of these techniques were compared with a reference or “gold standard” of mycobacterial culture and identification. Histopathology, the most rapid form of testing for M. bovis infection in white-tailed deer samples, had a sensitivity of 98% and a specificity of 87%, resulting in a …


Isovolumic Regulation In Nervous Tissue: A Novel Mechanism Of Cell Volume Regulation, O. Quesada, R. Franco, K. Hernandez-Fonseca, K. Tuz Jan 2000

Isovolumic Regulation In Nervous Tissue: A Novel Mechanism Of Cell Volume Regulation, O. Quesada, R. Franco, K. Hernandez-Fonseca, K. Tuz

School of Veterinary and Biomedical Sciences: Faculty Publications

Cell volume regulation is a property present in most animal cell lineages that allows them to recover their original volume after events of swelling or shrinkage. Such events can be caused by changes in external osmolarity or to osmotic gradients generated during normal cell functioning.4,6 The mechanism of cell volume regulation involves transmembrane fluxes of osmotically active solutes in the necessary direction to counteract the net gain or loss of intracellular water.9 The process through which cells recover their normal volume after swelling is named Regulatory Volume Decrease (RVD). This consists of the efflux of inorganic osmolytes, such as K …

Effects Of Bac On The Innervation Of Stomach, Berri̇n Gençer Tarakçi Jan 2000

Effects Of Bac On The Innervation Of Stomach, Berri̇n Gençer Tarakçi

Turkish Journal of Veterinary & Animal Sciences

Serosal application of BAC (benzalkonium chloride) to the pyloric antrum of the rat led to a complete loss of the intrinsic innervation of the treated region and also extensive loss of extrinsic sensory projections in the treated and untreated regions of the stomach. However, no changes were seen in the numbers of primary afferents projecting to the stomach, or expression of neuropeptides or neuronal proteins in the neurons. This finding is in marked contrast to the changes reported in sensory cell bodies after sectioning of the sciatic nerve, and suggested that visceral and somatic afferents may respond differently to axonal …
