the study was conducted to evaluate the effect of thermal stress on expression profile of genes related to apoptosis in peripartum sahiwal cows. for this, twelve pregnant dry sahiwal cows were selected from livestock research centre at national dairy research institute, karnal. the cows were divided into two groups consisting of six sahiwal cows each. cows of group i calved during thermoneutral...

One of the great challenges that the dairy industry faces, especially during the summer month, is heat stress. Increase in temperature, together with an increase in humidity, results in a decrease in milk production, feed intake, feed efficiency and even reduced growth rate in heifers (West, 1999). Reproduction and health are also negatively affected by heat stress (St Pierre et al., 2003). Dif...

This special issue reports the findings of a specialist workshop held in the summer of 2000, in Ann Arbor, Michigan. This introduction provides background information on HSRH imagery, briefly describes the major ways in which remote sensing data have been used previously for exposure assessment, presents the salient findings of the workshop, and places the papers resulting from the workshop wit...

I have been fortunate to have bad the opportunity to be associated with the TIPSTER Text Program since its inception in 1989. Preliminary discussions among government researchers who were interested in establishing a major, new interagency text handling, processing, and exploitation program began in the Summer of that year and continued in earnest during the months that followed. Most of our fr...

The sea cucumber Apostichopus japonicus is exploited as a commercial species owing to their high nutritive and medicinal value. Recent high summer temperatures have caused high mortality rates in A. japonicus. In this study, we applied the isobaric tag for relative and absolute quantitation (iTRAQ) technique to investigate the global protein expression profile under an acute short-term (48 h) h...

Recent investigations by the Australian Department of Agriculture, Fisheries and Forestry into high mortalities on live export voyages from Australia to the Middle East during the Northern hemisphere summer suggest that animal welfare may be compromised by heat stress. The live export industry has generated a computer model that aims to assess the risk of heat stress and to contain mortality le...

1. Summer drought stress is considered the primary constraint to plant performance in Mediterranean ecosystems. However, little is known about the implications of summer stress for plant reproduction under real field conditions and, particularly, for the regulatory mechanisms of maternal investment in reproduction. 2. The relationship between plant physiological status at different reproductive...

BACKGROUND & OBJECTIVES Immune activation and inflammation play critical roles in the stressful environmental conditions like high altitude, extreme cold, etc. Human leukocyte antigen-G (HLA-G) is a non classical major histocompatiblity complex class I (MHC class- I) protein, upregulated in the context of transplantation, malignancy and inflammation. We hypothesized serum HLA-G as a possible st...

We examined recruitment, survival, life cycle and fecundity of two metallicolous (M, on metalliferous calamine soils) and two non-metallicolous (NM, on normal soils) populations of Thlaspi caerulescens in Belgium and Luxemburg. In each population, permanent plots were monitored over two reproductive seasons. In M populations, plots were located in two contrasting environments (grass versus grov...
