A fixed procedure of strain gauge plethysmography in a control population aged between 20-30 years allows normal values for venous parameters (venous distensibility, emptying, and resistance) and capillary filtration coefficient, to be determined. High speed recording reveals two phases in venous emptying, one passive, purely elastic, and a second active phase, resulting from venous constriction.

The St. Lawrence Estuary (SLE) beluga () population in Canada is Endangered, and endocrine disrupting contaminants, such as polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), and other halogenated flame retardants, have been identified as a threat to the recovery of this population. Here, potential impacts of these contaminants on SLE beluga were evaluated by comparing skin transcriptome profiles and biological pathways between this population and a population less exposed to contaminants (Eastern Beaufort Sea) used as a reference.

Background: Previous studies have reported normative data for sagittal spinal alignment in asymptomatic adults. The sagittal spinal alignment change in European children was recently reported. However, there is a lack of studies on the normative reference values of sagittal spinal and pelvic alignment and how these parameters change at different growth stages in Chinese children.

Ecological ditches serve as one of the important measures for the concentrated infiltration of stormwater in the construction process of sponge cities. Prolonged concentrated infiltration of stormwater can lead to the accumulation of pollutants and pollution risks in the substrate of ecological ditches. In this study, two different substrate ecological ditches were constructed, namely, a combined substrate ecological ditch with zeolite + ceramsite (EA), and a biological substrate ecological ditch (EB).
