BACKGROUND The shortage of donor hearts has made use of non-beating hearts as cardiac grafts an attractive possibility for heart transplant candidates. The purpose of this study was to evaluate the utility of leukocyte-depleted hot shot cardioplegia for resuscitation of non-beating hearts obtained from asphyxiated dogs via an autoperfusing heart-lung circuit. METHODS Mongrel dogs were divided...

(continued on page 2) Trade winds generally blow to the west across the equatorial Pacific Ocean, piling up warm surface water in the west. In addition, there is a divergence of surface water at the equator due to Ekman transport away from this region. These forces set up a strong upwelling zone that extends westward from the coast of South America. This upwelling zone eventually encounters a l...

BACKGROUND Pre-cooling is known to enhance exercise performance in soccer players. However, little information currently exists regarding precooling effects in Iranian young soccer players. OBJECTIVES The aim of this study was to assess the effect of precooling (water immersion) on exhaustive performance in the heat ( temperature = 32 - 34°C, humidity = 50%). PATIENTS AND METHODS Sixteen yo...

[1] Satellite observations and chemistry-climate model experiments are used to understand the zonal structure of tropical lower stratospheric temperature, water vapor, and ozone trends. The warming in the tropical upper troposphere over the past 30 years is strongest near the Indo-Pacific warm pool, while the warming trend in the western and central Pacific is much weaker. In the lower stratosp...

Biological responses to warming are presently based on the assumption that species will remain within their bioclimatic envelope as environmental conditions change. As a result, changes in the relative abundance of several marine species have been documented over the last decades. This suggests that warming may drive novel interspecific interactions to occur (i.e. invasive vs. native species) o...

Two well established experimental stressors, hand immersion in cold water, and mental stimulation with dichotomous listening, were applied to 37 normal subjects after the ingestion of a standard meal. Orocaecal transit was measured by serial exhaled breath hydrogen sampling. Cold water significantly delayed transit compared with warm water control (warm water 71.8 +/- 3.6 mins v cold water 93.2...

Change in oceanographic conditions causes structural alterations in marine fish communities, but this effect may go undetected as most monitoring programs until recently mainly have focused on oceanography and commercial species rather than on whole ecosystems. In this paper, the objective is to describe the spatial and temporal changes in the Barents Sea fish community in the period 1992-2004 ...

CO 2 forcing is defined as the initial change in heating rate, with no feedbacks included, that is the direct response to an increase in the CO2 concentration in the atmosphere. We have conducted a study of the effects of surface temperature and clouds on the CO2 forcing, based on use of the Colorado State University general circulation model. We report results from a pair of perpetual July sim...
