background barrett’s oesophagus is a pre-malignant condition at gastroesophageal junction in which normal squamous epithelium is replaced by columnar shape epithelium, which predisposes oesophageal adenocarcinoma. it is known that barrett’s oesophagus evolves as a consequence of chronic gastro-oesophageal reflux disease. although progression of barrett’s oesophagus to adenocarcinoma is still un...

As the public becomes more knowledgeable about environmental concerns and health risks, the issue of public participation will become more challenging. The field of risk communication is a key element in environmental clean-up programs and continues to grow rapidly. Waste management organizations must move beyond past practices of simply reassuring the public and instead work to educate and act...

aqueous polyurethane dispersions (puds) have recently emerged as important alternatives to their solvent-based counterparts for various applications due to increasing health and environmental awareness (green chemistry). anionic polyester-polyurethane dispersions were synthesized by three steps. in the first step, macromonomer diisocyanate having carboxylic acid was prepared by isophorone diiso...

sperm is produced by the testis and mature in the epididymis. for having a successful conception, the fertilizing sperm should have functional competent membranes, intact acrosome, functional mitochondria and an intact haploid genome. the effects of genetic and environmental factors result in sperm vulnerability to damage in the process of spermatogenesis and maturation. in recent years, the fe...

This paper analyzes the effect of systems to manage environmental aspects on environmental performance at individual polluting facilities. Regulated polluting facilities are increasingly embracing pollution minimization strategies that involve the adoption of broadly defined systems to manage environmental aspects. Despite a meaningful empirical literature, whether or not these systems lead to ...

Environmental stress factors, including temperature, modify the severity of hypertension, a genetic disease. Hypertensive animals and humans respond abnormally to heat exposure, and this abnormality is reflected at the cellular level by an increment in a major stress (heat-shock) gene expression. The present studies demonstrate that increased hsp70 gene expression is due to its heightened trans...
