Abstract:

The aim of this thesis is to bring together and summarize the results of twenty-five years of active research into the immunology and physiology of the mammalian lymphoid system using the sheep as the model species. For this work I have exploited the cannulation of peripheral lymphatics, which enables the monitoring of lymph, lymphocytes and dendritic cells that are constantly trafficking from the skin or from lymph nodes. The use of this technique in the sheep permits access to large numbers of lymph-borne cells over extensive periods and in a form far closer to their <i>in vivo</i> non-activ

Abstract:

Bibliography: leaves 172-214. Interleukin-12 (IL-12) is a heterodimeric cytokine composed of two disulphide-linked subunits, p35 and p40, which form biologically active p70. IL-12 is able to induce IFN-y production from T and NK cells, and promote the proliferation of mitogen-activated T cells. It is thought that IL-12 may be an important cytokine in the initiation and progression of allograft destruction. This thesis describes the characterisation of ovine IL-12.

Abstract:

Spring-born ram lambs were used to examine: (1) sexual maturational changes in LH, FSH and prolactin (PRL) secretion, testicular gonadotropin receptors, and testicular size and function; (2) predictability of yearling ram reproductive function from juvenile testicular size and reproductive hormone measurements. Despite continuous increases in testis size, serum LH-profile characteristics became greatest between 2 and 4 months and declined thereafter. However, LH-peak frequency increased by about 2-fold between 6 and 7 months; this was associated with marked increases in testosterone (T) secret

Abstract:

Reproductive physiology in production animals is a key economic component of longevity and profitability of animal farming. There are several components that can benefit or compromise adequate pregnancy periods. Sheep production is not only a very important economic activity for farmers around the United States, but sheep are also an important medical and surgical model to study human diseases. Our findings suggest that estradiol-17 beta could be involved in acute increased plasma volume early in gestation which can benefit overall gestation. We report that umbilical blood flow decreases upon

This phenomenon occurs early in the cycle before the embryo’s can be collected and is a major contributor to failure in embryo transfer programs. This research was done to understand the physiological mechanisms involved.

Abstract:

Preimplantation sheep embryos were collected during the initial period of embryogenesis by flushing the uteri of ewes in situ at 13, 15, 17 and 19 days after mating. The embryos and associated embryonic structures (trophoblast, yolk sac and allantois) present at each age were separated for further investigation. An initial study established the lyophylised weight of embryonic structures present at each stage of development. These values were used as a basis for later comparison of the metabolism of these structures. Changes in the pool sizes of the macromolecules, glycogen, protein, DNA and RN

The term conjugated linoleic acid (CLA) refers to a range of geometric and positional isomers of linoleic acid. Recent research suggests a variety of potential health benefits with consumption of dietary CLA. These include a reduction in body fat deposition that has been demonstrated in a number of monogastric species including the mouse, rat, hamster and pig. This thesis describes the effects of CLA on lipid metabolism in sheep, where CLA may be useful in reducing carcass fat and improving fatty acid profile. The results are contrasted with those in the hamster, a model monogastric species, p

Abstract:

Adipose tissue is found in two main forms: white (WAT), which stores energy; and brown (BAT), which dissipates energy as heat by means of a unique mitochondrial protein, UCP1. In large mammals, BAT is rapidly replaced by WAT after birth, but it has recently been found that functional BAT is present in human adults, which raises the possibility that it could be manipulated to burn off excess fat. The main aim of this thesis was to investigate, using sheep as a model, the effect of early nutritional interventions on fat mass and on the expression in adipose tissue of genes involved in adipogenes

Decompression sickness (DCS) results from a sudden decrease in ambient pressure leading to super-saturation of tissues with inert gas and subsequent bubble formation within both tissues and blood.

PFC emulsions reduce both morbidity and mortality of DCS, but the mechanism of this protective effect has not yet been demonstrated.

Le Bisphénol A (BPA) est un perturbateur endocrinien dont les effets développementaux observés chez les rongeurs soulèvent la question du risque pour la santé humaine relatif à une exposition fœtale au BPA. L’objectif de cette thèse est de déterminer les mécanismes toxicocinétiques impliqués dans l’exposition fœtale au BPA. La caractérisation in vivo dans un modèle intégratif ovin des expositions maternelles et fœtales au BPA et à ses métabolites ont permis d’identifier le transfert placentaire et le métabolisme fœto-placentaire comme les déterminants majeurs de l’exposition fœtale au BPA.

Abstract:

L'utilisation d'antiserums reconnaissant la serotonine et les enzymes de synthese des catecholamines a permis la mise en evidence, par immunocytochimie, des structures serotoninergiques et catecholaminergiques dans le snc du mouton. Des investigations identiques faites chez le foetus ont permis de montrer une apparition tres precoce de ces amines dans le snc. Le developpement des structures serotoninergiques est precoce et rapide, plus que celui des structures catecholaminergiques
