The invention discloses an unpowered water purification system for a riverfront landscape constructed wetland, comprising a riparian wetland constructed along a lake-land ecotone of a river, lake-pond. The riparian wetland comprises a plurality of alternatively arranged wetland islands and watercourses formed between them. The bottom surface of the riparian wetland is lower than the normal water level of the river, lake-pond, and the upper surface of the wetlands is flush with the normal water level of the river, lake-pond. Plants are planted on the wetlands. A revetment is constructed between the riparian wetland and the river, lake-pond, and its upper surface is between the bottom surface of the riparian wetland and the upper surface of the wetlands. The invention achieves good purification and landscape effects. The purification system has some advantages such as good landscape effects, simple management without energy and power consumption, and thus is durable and stable.

Zinc-air is a century-old battery technology but has attracted revived interest recently. With larger storage capacity at a fraction of the cost compared to lithium-ion, zinc-air batteries clearly represent one of the most viable future options to powering electric vehicles. However, some technical problems associated with them have yet to be resolved. In this review, we present the fundamentals, challenges and latest exciting advances related to zinc-air research. Detailed discussion will be organized around the individual components of the system-from zinc electrodes, electrolytes, and separators to air electrodes and oxygen electrocatalysts in sequential order for both primary and electrically/mechanically rechargeable types. The detrimental effect of CO2 on battery performance is also emphasized, and possible solutions summarized. Finally, other metal-air batteries are briefly overviewed and compared in favor of zinc-air. This journal is © the Partner Organisations 2014.

Previous studies suggest obstructive sleep apnea (OSA) may increase cardiovascular risk, but the results are inconclusive due to various limitations. We aimed to systematically evaluate the effect of OSA on the incidence of cardiovascular events by a meta-analysis of prospective cohort studies. We searched multiple electronic databases for studies that examined the prospective relationship between OSA and incidence of coronary heart disease (CHD), stroke, or total cardiovascular diseases (CVD) among adults. Either fixed- or random-effects models were used to calculate the pooled risk estimates. Sensitivity analysis was conducted to examine the robustness of pooled outcomes. Of 17 studies included, 9 reported results on total CVD, 7 reported on fatal or non-fatal CHD, and 10 reported on fatal or non-fatal stroke. The pooled relative risks (95% confidence interval) for individuals with moderate-severe OSA compared with the reference group were 2.48 (1.98-3.10) for total CVD, 1.37 (0.95-1.98) for CHD, and 2.02 (1.40-2.90) for stroke. These results did not materially change in the sensitivity analyses according to various inclusion criteria. In conclusion, findings from this meta-analysis supported that moderate-severe OSA significantly increased cardiovascular risk, in particular stroke risk. Copyright © 2013 Elsevier Ireland Ltd.

Semaphorin 4D (Sema4D) is a transmembrane protein that supports contact-dependent amplification of platelet activation by collagen before being gradually cleaved by the metalloprotease ADAM17, as we have previously shown. Cleavage releases a soluble 120-kDa exodomain fragment for which receptors exist on platelets and endothelial cells. Here we have examined the mechanism that regulates Sema4D exodomain cleavage. The results show that the membrane-proximal cytoplasmic domain of Sema4D contains a binding site for calmodulin within the polybasic region Arg762-Lys779. Coprecipitation studies show that Sema4D and calmodulin are associated in resting platelets, forming a complex that dissociates upon platelet activation by the agonists that trigger Sema4D cleavage. Inhibiting calmodulin with W7 or introducing a membrane-permeable peptide corresponding to the calmodulin-binding site is sufficient to trigger the dissociation of Sema4D from calmodulin and initiate cleavage. Conversely, deletion of the calmodulin-binding site causes constitutive shedding of Sema4D. These results show that (1) Sema4D is a calmodulin-binding protein with a site of interaction in its membrane-proximal cytoplasmic domain, (2) platelet agonists cause dissociation of the calmodulin-Sema4D complex, and (3) dissociation of the complex is sufficient to trigger ADAM17-dependent cleavage of Sema4D, releasing a bioactive fragment.

Ag@C core-shell nano-composites have been prepared by a simple one-step hydrothermal method and are further explored for protein immobilization and bio-sensing. The electrochemical behavior of immobilized horseradish peroxidase (HRP) on Ag@C modified indium-tin-oxide (ITO) electrode and its application as H2O2 sensor are investigated. Electrochemical and UV-vis spectroscopic measurements demonstrated that Ag@C nano-composites provide excellent matrixes for the adsorption of HRP and the entrapped HRP retains its bioactivities. It is found that on the HRP-Ag@C/ITO electrode, HRP exhibited a fast electron transfer process and good electrocatalytic reduction toward H2O2. Under optimum experimental conditions the biosensor linearly responds to H2O2 concentration in the range of 5.0×10-7-1.4×10-4 M with a detection limit of 2.0×10-7 M (S/N=3). The apparent Michaelis-Menten constant (K(app)(M)) of the biosensor is calculated to be 3.75×10-5 M, suggesting high enzymatic activity and affinity toward H2O2. In addition, the HRP-Ag@C/ITO bio-electrode shows good reproducibility and long-term stability. Thus, the core-shell structured Ag@C is an attractive material for application in the fabrication of biosensors due to its direct electrochemistry and functionalized surface for efficient immobilization of bio-molecules.
