background: an explosion of research has been done in discovering how human health is affected by environmental factors. i will discuss the impacts of environmental cancer causing factors and how they continue to cause multiple disruptions in cellular networking. some risk factors may not cause cancer. other factors initiate consecutive genetic mutations that would eventually alter the normal p...

The environmental quality of destination has become a tool that hotels have to hold the tourism demand. In this paper we are going to present a model of vertical differentiation in the accommodation industry, where differentiation is associated with quality. Additionally, we assume the existence of a lump sum tax in the accommodation industry. Two are the main results which will be proved in th...

In this paper, we construct a political-economy model of international noncooperative environmental policymaking, and examine the strategic incentives for voters to elect an environmental policymaker in open economies. We show that under several circumstances, citizens have an incentive to deliberately vote for a candidate whose environmental preferences differ from their own. Further, the stra...

Evidence from a number of studies (e.g. Holtzer, 1964; Coon & Cahn, 1966; Konigsberg, 1963) has suggested that the differentiation of some types of cells in vitro may be influenced by environmental factors. Culture conditions can permit or prevent the phenotypic expression of characteristics already determined in the cells. The length of time involved in the stabilization of differentiation app...

A growing number of environmental toxicants found in pesticides, herbicides, and industrial solvents are believed to have deleterious effects on development by disrupting hormone-sensitive processes. We exposed Xenopus laevis embryos at early gastrula to the commonly encountered environmental estrogens nonylphenol, octylphenol, and methoxychlor, the antiandrogen, p,p-DDE, or the synthetic andro...

Introduction In vitro expansion and differentiation of mesenchymal stem cells (MSCs) rely on specific environmental conditions. One crucial factor is the oxygen tension. Low oxygen tension improves MSC expansion in vitro. Moreover, it accelerates the induction of a chondrogenic phenotype in subsequent 3D differentiation cultures. However, clones of MSCs from the same donor often differ in their...

Data from 183 animals raised in 61 flocks were collected to investigate the morphological characteristics of the Northern Morocco goat. Nine zoometric measures and seven combined indices were obtained. Three zones were defined  based on geo-climatic characteristics and environmental influences: Mediterranean, Atlantic and Dual. The morphological variables showed the absence of sexual dimorphism...
