THE REDUCTION in metabolic rate effected by hypothermia constitutes the central tenet of traditional organ preservation. The antithesis of this approach is to provide for metabolic demand during normothermic preservation. This latter strategy has two potential benefits. First, if metabolic requirements are met during preservation, then longer preservation with better posttransplant function may...

Understanding rumen–reticulum fill dynamics gives us insight into how environmental conditions influence animal behaviors that affect when animals access forage. We examined whether there were daytime declines in rumen–reticulum fill in response to high ambient temperatures in free-ranging white-tailed deer (Odocoileus virginianus (Zimmermann, 1780)) on a diurnal scale. We hypothesized that to ...

Case Description- A 1-year-old female Domestic Shorthair cat weighing 2.5 kg with one week history of protruding mass from the vulva was admitted. Clinical Findings- The prolapse was complete involving both horns protruding from the vulva and a soft bulging mass was palpable inside the prolapsed uterus. Treatment and Outcome- The prolapsed organ was irrigated with warm saline soluti...

Investigators have expressed interest in the associations between resting energy expenditure (REE) and body mass for over a century. Traditionally, descriptive models using regression analysis are applied, linking REE with metabolically active compartments such as body cell mass (BCM) and fat-free body mass (FFM). Recently developed whole body magnetic resonance imaging (MRI) and echocardiograp...

The purpose of this study was to determine whether overfeeding and high-intensity physical training increase organ mass. We examined this question using cross-sectional and longitudinal studies in which we measured collegiate male American football players. Freshman (n = 10) and senior players in their second and third years of college (n = 17) participated in the cross-sectional study. The sam...

Hypoxia inhibits vertebrate development, but the magnitude and timing of organ-specific effects are poorly understood. Chick embryos were exposed continuously to hypoxia (15% O2) throughout Days 1-6, 6-12, 12-18 or Days 1-18 of development, followed by morphometric measurements of major organ systems. Early hypoxic exposure reduced eye mass and beak length when measured in middle development. L...

BACKGROUND Most preclinical studies are carried out on mice. For internal dose assessment of a mouse, specific absorbed fraction (SAF) values play an important role. In most studies, SAF values are estimated using older standard human organ compositions and values for limited source target pairs. OBJECTIVE SAF values for monoenergetic photons of energies 15, 50, 100, 500, 1000 and 4000 keV we...

introduction: the purpose of this study was to compare estimation of radiation absorbed doses to patients following bone scans with technetium-99m-labeled methylene diphosphonate (mdp) with the estimates given in mirdose software. methods: in this study, each patient was injected 25 mci of 99m tc-mdp. whole-body images from thirty patients were acquired by gamma camera at 10, 60, 90, 180 minute...

The potential complications associated with an adnexal mass discovered during early pregnancy call for surgical treatment. Ideally, surgery is performed after gestational week 12, but uterine expansion after the first trimester makes surgery difficult. We report two pregnancies complicated by adnexal masses for which we used an organ fixation device for safe performance of single-site umbilical...
