Background: A paradoxical profile of greater elevated sympathetic vasoconstriction (increased total peripheral resistance, TPR) and increased vagally-mediated heart rate variability (HRV) -the so-called Cardiovascular Conundrum- has been reported in African Americans (AAs) both at rest and in response to orthostasis.Whereas some authors have attrib
Analytical solutions for a one-line model for shoreline changes are employed to investigate the formation of two wave-dominated river delta coastlines, along with a small-scale laboratory experiment.Since the present analytical solution can be applied only to a river delta with infinite shorelines, a new analytical solution was developed to conside
Meiosis is a complex type of cell division that involves homologous chromosome pairing, synapsis, recombination, and segregation.When any of these processes is altered, cellular checkpoints arrest meiosis progression and induce cell elimination.Meiotic impairment is particularly frequent in organisms bearing chromosomal translocations.When chromoso
In France, two years after the catastrophic industrial accident of Toulouse, a new law was introduced on July 30, Pet Shirt 2003 which created the Technological Risk Prevention Plan (PPRT in French, standing for Plan de Prevention des Risques Technologiques).The aim of the PPRT is to protect people by action on the existing urbanization and by cont
Tropical deforestation is leading to a loss of economically productive timber concessions, as well as areas with important environmental or socio-cultural values.To counteract this threat in Southeast Asia, sustainable forest management (SFM) practices are becoming increasingly important.We assess the tools and guidelines that have been developed t
