Adipogenesis is accompanied by differentiation of adipose tissuederived stem cells to adipocytes. As part of this differentiation, biogenesis of the oxidative phosphorylation system occurs. Many chemical compounds used in medicine, agriculture or other human activities affect oxidative phosphorylation function. Therefore, these xenobiotics could alter adipogenesis. We have analyzed the effects ...

background: in the field of cellular therapy, the impact of confluence degree to harvest or differentiate bmmscs and the effect of cell-to-cell contact remains controversial. therefore, the effect of confluence on bmmscs properties was studied and confluence-associated osteogenic differentiation efficiency was identified. materials and methods: the impact of confluences at 20, 50, 70, 80 and 10...

The aryl hydrocarbon receptor (AHR) is an environmental sensor and ligand-activated transcription factor that involved in epithelial homeostasis barrier development of the skin. Through genome-wide transcriptomic epigenomic analyses human primary keratinocytes upon AHR activation using TCDD we identified early late responsive genes. genes were enriched for canonical factors known to promote ker...

Cavity ring-down (CRD) is a sensitive variant of traditional absorption spectroscopy that has found increasing use in a number of chemical measurement applications. This review focuses on applications of cavity ring-down spectroscopy that will be of interest to environmental chemists and analytical chemists working on environmental problems. The applications are classified into direct monitorin...

This article uses adopts a revised version of the concept techno-environmental habitus to investigate and make sense differentiation among digital technology users’ attitudes towards environment in England. Digital–environmental refers combination structural determinants (existing background) metabolised increased use technologies people’s everyday life that also interacts with individual envir...

Specific environmental taxes are minor in relation to fuel excise duty, road tolls and annual taxes on the ownership or use of vehicles, in terms of their cost to transport operators and users (see the OECD environmental tax data base). Although differentiation of general transport taxes on the basis of environmental performance is quite widely used to leverage vehicle purchase decisions, this ...

objective(s): throughout evolution, mammalians have increasingly lost their ability to regenerate structures however rabbits are exceptional since they develop a blastema in their ear wound for regeneration purposes. blastema consists of a group of undifferentiated cells capable of dividing and differentiating into the ear tissue. the objective of the present study is to isolate, culture expand...

Sexual reproduction in an environmental pathogen helps maximize its lineage fitness to changing environment and the host. For the fungal pathogen Cryptococcus neoformans, sexual reproduction is proposed to have yielded hyper virulent and drug resistant variants. The life cycle of this pathogen commences with mating, followed by the yeast-hypha transition and hyphal growth, and it concludes with...

There is increasing evidence that species can evolve rapidly in response to environmental change. However, although land use is one of the key drivers of current environmental change, studies of its evolutionary consequences are still fairly scarce, in particular studies that examine land-use effects across large numbers of populations, and discriminate between different aspects of land use. He...

In mammals, germ cell differentiation is initiated in the Primordial Germ Cells (PGCs) during fetal development. Prenatal exposure to environmental toxicants such as endocrine disruptors may alter PGC differentiation, development of the male germline and induce transgenerational epigenetic disorders. The anti-androgenic compound vinclozolin represents a paradigmatic example of molecule causing ...
