The current study demonstrated that the prevalence of metabolic syndrome was dramatically high in hypertensive women, even in the rural areas of China. Further, our study indicated that remarkable ethnic differences exist in the prevalence of metabolic syndrome. Obese and moderate levels of physical activity were a modifiable risk factor.

Developing high-active and low-cost bifunctional materials for catalyzing the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) holds a pivotal role in water splitting. Therefore, we present a new strategy to form NiS/NiP heterostructures. The as-obtained NiS/NiP/carbon cloth (CC) requires overpotentials of 111 mV for the HER and 265 mV for the OER to reach a current density of 20 mA cm, outperforming their counterparts such as NiS and NiP under the same conditions. Additionally, the NiS/NiP/CC electrode requires a 1.67 V cell voltage to deliver 10 mA cm in a two-electrode electrolysis system, which is comparable to the cell using the benchmark Pt/C||RuO electrode. Detailed characterizations reveal that strong electronic interactions between NiS and NiP, abundant active sites, and smaller charge-transfer resistance contribute to the improved HER and OER activity.

Early life-cycle events play critical roles in determining the population and community dynamics of plants. The ecology of seeds and their germination patterns can determine range limits, adaptation to environmental variation, species diversity, and community responses to climate change. Understanding the adaptive consequences and environmental filtering of such functional traits will allow us to explain and predict ecological dynamics. Here we quantify key functional aspects of germination physiology and relate them to an existing functional ecology framework to explain long-term population dynamics for 13 species of desert annuals near Tucson, Arizona, USA. Our goal was to assess the extent to which germination functional biology contributes to long-term population processes in nature. Some of the species differences in base, optimum, and maximum temperatures for germination, thermal times to germination, and base water potentials for germination were strongly related to 20-yr mean germination fractions, 25-yr average germination dates, seed size, and long-term demographic variation. Comparisons of germination fraction, survival, and fecundity vs. yearly changes in population size found significant roles for all three factors, although in varying proportions for different species. Relationships between species' germination physiologies and relative germination fractions varied across years, with fast-germinating species being favored in years with warm temperatures during rainfall events in the germination season. Species with low germination fractions and high demographic variance have low integrated water-use efficiency, higher vegetative growth rates, and smaller, slower-germinating seeds. We have identified and quantified a number of functional traits associated with germination biology that play critical roles in ecological population dynamics.
