Despite the pervasive use of social media by young adults, there is comparatively little known about whether, and how, engagement in social media influences this group's drinking patterns and risk of alcohol-related problems. We examined the relations between young adults' alcohol-related social media engagement (defined as the posting, liking, commenting, and viewing of alcohol-related social media content) and their drinking behavior and problems. We conducted a systematic review and meta-analysis of studies evaluating the association of alcohol consumption and alcohol-related problems with alcohol-related social media engagement...

Ammonia is recognised as a major pollutant worldwide, originating from natural and anthropogenic sources. Studies have reported that freshwater mussels are amongst the most sensitive taxa to ammonia, but there is a lack of data available on ammonia toxicity for the early life stages of freshwater mussels from tropical regions. This paper reports the modification of a 24-h acute toxicity test protocol for tropical freshwater mussels and application of the test using ammonia. Velesunio spp. from three different sites were used to assess the toxicity of ammonia at a targeted pH of 6...

BACKGROUND: An intraocular lens (IOL) is a synthetic lens that is surgically implanted within the eye following removal of the crystalline lens, during cataract surgery. While all modern IOLs attenuate the transmission of ultra-violet (UV) light, some IOLs, called blue-blocking or blue-light filtering IOLs, also reduce short-wavelength visible light transmission. The rationale for blue-light filtering IOLs derives primarily from cell culture and animal studies, which suggest that short-wavelength visible light can induce retinal photoxicity...

Traumatic axonal injury (TAI) contributes significantly to mortality and morbidity after traumatic brain injury (TBI) but its identification is still a diagnostic challenge because of the limitations of conventional imaging techniques to characterized it. Diffusion tensor imaging (DTI) can indirectly identify areas of damaged white matter (WM) integrity by detecting water molecules diffusion alterations. Therefore, DTI may improve detection and description of TAI lesions after TBI. We have obtained DTI data from 217 patients with moderate to severe TBI acquired at median 19 days after TBI were and patient DTI metrics were compared with data obtained from 58 age-matched healthy controls...

Mild traumatic brain injury (mTBI) is an important public health problem. Although conventional medical imaging techniques can detect moderate-to-severe injuries, they are relatively insensitive to mTBI. In this study, we used hybrid diffusion imaging (HYDI) to detect white-matter alterations in nineteen patients with mTBI and 23 other trauma-control patients. Within 15 days (SD=10) of brain injury, all subjects underwent magnetic-resonance HYDI and were assessed with battery of neuropsychological tests of sustained attention, memory, and executive function...

This paper reports a new method for the generation of substituted 1,3-enynes, whose synthesis by other methods could be a challenge. The dehydrative decarboxylative cascade coupling reaction of propargyl alcohol with alkyl peroxides is enabled by an iron catalyst and alkylating reagents. Primary, secondary, and tertiary alkyl groups can be introduced into 1,3-enynes, affording various substituted 1,3-enynes in moderate to good yields. Mechanistic studies suggest the involvement of a radical-polar crossover pathway...

The first oxidative C(sp3)-H phosphonylation of tertiary aliphatic amines has been developed. The use of cobalt acetate as catalyst, N-hydroxyphthalimide as co-catalyst, and air as oxidant enabled the conversion of tertiary aromatic and aliphatic amines into α-aminophosphonates in moderate to excellent yields under mild conditions via a cross dehydrogenative coupling reaction.

Block copolymer materials have been considered as promising candidates to fabricate gas separation membranes. This microphase separation affects the polymer chain packing density and molecular separation efficiency. Here we demonstrate a method to template microphase separation within a thin composite Pebax membrane, through the controllable self-assembly of one-dimensional halloysite nanotubes (HNTs) within the thin film via solution casting technique. Crystallisation of the polyamide component is induced at the HNT surface, guiding subsequent crystal growth around the tubular structure...

BACKGROUND: Many patients with tetralogy of Fallot (TOF) who underwent surgical correction of their congenital cardiac malformation during infancy develop right ventricular dysfunction and exercise intolerance in the long term. The right ventricle (RV) dilates due to the development of severe pulmonary regurgitation (and secondary tricuspid insufficiency). To reduce RV dilation and improve exercise tolerance pulmonary valve replacement (PVR) is the common therapeutic strategy. Whether concomitant tricuspid valve repair (TVR) is beneficial in these pure volume-overload conditions is still unknown...

BACKGROUND: Endovascular treatment offers an alternative less-invasive approach to open repair for subclavian artery atherosclerotic disease (SAAD). However, only few studies compared the outcomes of both strategies in the long run. This study reports on the performance of endovascular and surgical revascularization for SAAD. METHODS: A retrospective review was conducted on patients treated for SAAD at two institutions between January 1998 and December 2015. Primary outcome of this study was the composite endpoint of re-intervention-free survival (RFS) defined as time to re-intervention and/or death from any cause...
