A true moderniser of equine practice.

recently celebrated his 90th birthday. Tim Greet describes the career of this pioneering equine vet.

An Account of 'Life after Guantánamo': a rehabilitation project for former Guantánamo detainees across continents.

This paper describes a project established in 2009 by the human rights charity, Reprieve, to coordinate rehabilitation for men who have been released from long-term detention at the US military base of Guantánamo Bay. The majority of the men referred to the project were deemed unable to return to their home country because of the risk they faced of torture or other persecution and were therefore resettled in a third country. This paper also refers to Tunisian former Guantánamo detainees with whom Reprieve worked, who had initially been resettled in a third country but then following the Jasmine Revolution and the fall of the Ben Ali regime, were able to return to their home country.

Fifty years of the British Equine Veterinary Association as a facilitator of progress in equine clinical science.

The British Equine Veterinary Association (BEVA) was established in 1961 and launched the Equine Veterinary Journal (EVJ) in 1968. This review outlines some of the major advances in equine science and practice that have occurred in that time and the role played by the Journal in facilitating those developments.

Development of baroreflex and endocrine responses to hypotensive stress in newborn foals and lambs.

Objective: The aims of this study were to compare and contrast the development of the cardiac baroreflex and endocrine responses to acute hypotensive stress in healthy newborn pony foals and lambs during the first two weeks of postnatal life.

Methods: Under general anaesthesia, seven Welsh pony foals and six Welsh Mountain lambs were catheterised with hind limb artery and vein catheters. Following post-surgical recovery, at 1 week and 2 weeks of age, blood pressures of the animals were raised and lowered acutely by intravenous infusion of phenylephrine and sodium nitroprusside, respectively.

Progestagen profiles during the last trimester of gestation in Thoroughbred mares with normal or compromised pregnancies.

Progesterone (P4), pregnenolone (P5) and their metabolites are present in maternal plasma in pregnant mares. It is believed that one of these progestagens may maintain myometrial quiescence. The aims of this study were to identify specific progestagens in pregnant mares' plasma and determine whether these differed between mares with healthy or compromised pregnancies.

Effects of manipulating intrauterine growth on post natal adrenocortical development and other parameters of maturity in neonatal foals.

Reasons For Performing Study: Intrauterine growth retardation (IUGR) impairs post natal adaptive responses and is associated with increased adrenocortical activity in many species.

Objectives: To determine whether a restricted or enhanced intrauterine environment affects neonatal adaptation and adrenocortical function in horses.

Methods: Embryos from large (577 kg) Thoroughbred (TB) mares were transferred to smaller (343 kg) pony (P) mares and vice versa, to create a restricted (TB-in-P, n = 11) or enhanced (P-in-TB, n = 8) intrauterine environment.

Ontogeny of uteroplacental progestagen production in pregnant mares during the second half of gestation.

In pregnant mares during late gestation, little, if any, progesterone (P4) is found in the maternal circulation. Hence, quiescence of the equine uterus is believed to be maintained by metabolites of pregnenolone and P4 known as progestagens, which are produced by the uteroplacental tissues. However, little is known about the ontogeny, distribution, or actual rates of uteroplacental progestagen production in pregnant mares and their fetuses during the second half of pregnancy.

Influence of maternal size on placental, fetal and postnatal growth in the horse. I. Development in utero.

The interacting influences of maternal size and fetal genotype on placental and fetal development in the mare were assessed by comparing conventional within-breed Thoroughbred (Tb-in-Tb, n = 7) and Pony (P-in-P, n = 7) control pregnancies established by artificial insemination (AI) with between-breed (Tb-in-P, n = 8; deprived in utero condition and P-in-Tb, n = 7; luxurious in utero condition) experimental pregnancies established by embryo transfer. All foals were born spontaneously and the mean (+/- SEM) duration of gestation in the two groups of control mares was significantly different (P < 0.001) at 325 +/- 3.
