The impact of the composition of blends comprising low‐density polyethylene(LDPE),isotactic polypropylene(PP)and a styrenic copolymer additive on the thermomechanical properties as well as the direct‐current(DC)electrical and thermal conductivity is *** presence of 5 weight percent(wt%)of the styrenic copolymer strongly reduces the amount of PP that is needed to enhance the storage modulus above the melting temperature of LDPE from 40 to 24 wt%.At the same time,the copolymer improves the consistency of the thermomechanical properties of the resulting ternary *** both the DC electrical and thermal conductivity strongly decrease with PP content,the addition of the styrenic copolymer appears to have little influence on either ***,PP in combination with small amounts of a styrenic copolymer not only allows to reinforce LDPE at elevated temperatures but also functions as an electrical conductivity‐reducing additive,which makes such thermoplastic ternary formulations possible candidates for the insulation of high‐voltage power cables.

We report a 14-year-old patient with recurrent pulmonary embolism due to catastrophic antiphospholipid syndrome (APS) with severe pulmonary inflammation. We considered elevated antibodies against cardiolipin and anti-beta2-glycoprotein-1, but no clinical nor laboratory manifestations of systemic lupus erythematosus (SLE). Pulmonary embolism had been the first manifestation of catastrophic APS in this patient. We prescribed warfarin and systemic corticosteroids. A second embolism appeared during anticoagulation with warfarin. This event led to a marked decrease of his physical performance due to his obstructive and restrictive lung disease. Anticoagulation was changed from enteral warfarin to subcutaneous enoxaparine. We also prescribed inhaled corticosteroid which led to an improvement of his respiratory symptoms and overall poor physical condition.

The long-term effects of physical activity （PA） or sedentary behavior on cardiovascular health in young people are not well understood. In this study, we use a narrative format to review the evidence for a prospective association with adiposity and other well-established biological cardiovascular risk factors in healthy young people, considering only studies with at least 2 years of follow-up. PA appears to elicit a long-term beneficial effect on adiposity and particularly markers of cardiovascular health. With adiposity, however, a few studies also reported that higher levels of PA were associated with higher levels of adiposity. Time spent sedentary does not appear to be related to adiposity or markers of cardiovascular health independent of PA. We then discuss the uncertainties in the underlying causal chain and consider a number of alternative modeling strategies, which could improve our understanding of the relationship in future studies. Finally, we consider the current methodology for assessing PA and sedentary time.

Triazaphospholes(TAPs) as a fascinating class of low-coordinate phosphourus heterocycle compounds, containing a conjugated π system with high degree of aromaticity and a rather high π density at the phosphorus atom have also attracted much interest over the past decades. 3 H-1,2,3,4-triazaphospholes as phosphorus analogues of the well-documented 1,2,3-triazoles, first reported by Regitz et al. in 1984, were prepared by a [3+2] cycloaddition reaction of phosphaalkynes with azides in the absence of the requirement of a catalyst. Until now, mainly TAPs with electron donating substituents have been extensively investigated. In order to gain further insight into the scope of TAPs, we start to explore the reactivity and coordination chemistry of the TAPs containing an electron-withdrawing tosyl group. Herein we report on the synthesis and characterization of the tosyl-substituted 3 H-1,2,3,4-triazaphospholes(1 a, b) and their gold(I) complexes(2 a, b) based on cyclo-1,3-diphospha-2,4-diazanes, which confirmed by single crystal X-ray crystallography analyses. By investigation the proposed mechanism of the reaction, it is notable that the tert-butyl group were converted into the iso-pentenyl substituents by methyl migration besides obvious spontaneous nitrogen extrusion which monitored by GC-TCD. The phosphorus atoms were coordinated with gold(I) precursor, respectively. The trapping experiments also showed that a key intermediate iminophosphine was confirmed by ESI-mS.
