Gastroduodenal stenting using self-expandable metallic stents (SEMSs) represents a viable endoscopic option for palliative treatment of gastric outlet obstruction (GOO), less invasive relative to surgical and/or endoscopic ultrasound-guided gastroenterostomy (EUS-GE). Nevertheless, high rates of stent dysfunction remain a significant Achilles' heel of the procedure. Endoscopic removal of a distally migrated gastroduodenal stent remains challenging with single-channel techniques, calling for individually tailored solutions vis-à-vis the inevitable upstream stricture...

Here we choose a dihydronaphthyl-functionalized C60 fullerene as a building block and utilize a novel solvent knitting strategy based on Friedel-Crafts alkylation reaction to construct two kinds of novel porous materials by using dichloromethane (DCM) and 1,2-dichloroethane (DCE) as solvents and external crosslinkers. The resulting porous materials show relatively high apparent BET surface areas and gas uptake abilities.

Hypercrosslinked polymers (HCPs) are currently receiving great attention due to their unique characteristics and potential uses in diverse areas. However, the field of HCPs for open-tubular capillary electrochromatography (OT-CEC) separations has not been explored. Here, a knitted aromatic polymer (KAP) was in-situ grown on the inner wall of the capillary column for OT-CEC for the first time. The silylating reagent containing phenyl was served as monomer, immobilized on the inner wall of the capillary column, and then KAPs-modified capillary column was prepared through in-situ hypercrosslinking reaction...

Fiber shaped strain sensors with great flexibility and knittability have been tremendously concerned due to the wide applications in health manager devices, especially in human motion detection and physicalogical signal monitoring. Herein, a novel fiber shaped strain sensor has been designed and prepared by interpenetrating AgNWs into POE nanofibrous yarn. The easy-to-obtain structure and simple roll-to-roll process make the continuous large-scale production of nanofibrous composite yarn possible. The continuous and alternating stretching and releasing reversibly change the contact probability between AgNWs in this interpenetrating networks, leading to the variations of electrical resistance of the sensor...

A new and more alarming source of marine contamination has been recently identified in micro and nanosized plastic fragments. Microplastics are difficult to see with the naked eye and to biodegrade in marine environment, representing a problem since they can be ingested by plankton or other marine organisms, potentially entering the food web. An important source of microplastics appears to be through sewage contaminated by synthetic fibres from washing clothes. Since this phenomenon still lacks of a comprehensive analysis, the objective of this contribution was to investigate the role of washing processes of synthetic textiles on microplastic release...

CONTEXT:   The National Athletic Trainers' Association recommends using onsite wet-bulb globe temperature (WBGT) measurement to determine whether to modify or cancel physical activity. However, not all practitioners do so and instead they may rely on the National Weather Service (NWS) to monitor weather conditions. OBJECTIVE:   To compare regional NWS WBGT estimates with local athletic-surface readings and compare WBGT measurements among various local athletic surfaces...

Behçet's disease (BD) is a chronic relapsing vasculitis that affects vessels of all types and sizes with a broad spectrum of phenotypic heterogeneity and complex immunopathogenesis. Efforts by the scientific community to resolve the unmet needs of BD and gaps in our knowledge have been hampered by considerable challenges that primarily relate to the rare nature of the disease in many parts of the world and its heterogeneity. Controversies remain in many aspects of the disease including the diagnostic criteria, immunopathogenesis and biomarker discovery, geographical variation, and therapeutic considerations...

Microplastics in the environment are a subject of intense research as they pose a potential threat to marine organisms. Plastic fibers from textiles have been indicated as a major source of this type of contaminant, entering the oceans via wastewater and diverse non-point sources. Their presence is also documented in terrestrial samples. In this study, the amount of microfibers shedding from synthetic textiles was measured for three materials (acrylic, nylon, polyester), knit using different gauges and techniques...

Currently, no published standard and research work have addressed the basic requirements on knitted fabric 'skin' on sweating manikins. In this study, we performed 252 experiments to investigate the influence of fabric thickness and material on the apparent 'wet' conductive (or effective) thermal resistance of the fabric 'skin' using a 'Newton' manikin. Four types of cotton fabric 'skin' (fabric thickness: 0.38, 0.54, 0.92 and 1.43mm) and three types of polyester fabric 'skin' (fabric thickness: 0.41, 0.54 and 1...

Today, intellectual property (IP) scholars accept that IP as an approach to information production has serious limits. But what lies beyond IP? A new literature on "intellectual production without IP" (or "IP without IP") has emerged to explore this question, but its examples and explanations have yet to convince skeptics. This Article reorients this new literature via a study of a hard case: a global influenza virus-sharing network that has for decades produced critically important information goods, at significant expense, and in a loose-knit group--all without recourse to IP...

Hierarchical porous polymers with more than one pore size distributions can effectively support noble metal catalysts and circumvent the limitation of the diffusion of the reactants, and thus exhibit both excellent catalytic activity and superior diffusive properties. Herein, we report a simple one-step Friedel-Crafts reaction to knit a series of benzene heterocycle monomers, such as indane, indoline, indole and tetrahydronaphthalene to obtain hierarchical porous polymers with high surface areas and/or abundant N sites...

This review provides a historical overview of the inception and development of bioinformatics research in the Netherlands. Rooted in theoretical biology by foundational figures such as Paulien Hogeweg (at Utrecht University since the 1970s), the developments leading to organizational structures supporting a relatively large Dutch bioinformatics community will be reviewed. We will show that the most valuable resource that we have built over these years is the close-knit national expert community that is well engaged in basic and translational life science research programmes...

Lymphoedema results from a failure of the lymphatic system. The consequences are swelling, skin and tissue changes and predisposition to infection. Lipoedema, however, results from the predisposition of an excessive number of fat cells in the lower limbs, typically from the ankle to the waist. Management for lymphoedema consists of volume reduction, reduction in shape distortion and improvement of skin condition. Treatment consists of a two-phase approach including an intensive and maintenance phase. The maintenance stage of treatment or self-care consists of skin care, exercise and compression garments...

Lymphoedema is a chronic disease affecting the patients' quality of life (QoL) especially with regard to mobility and daily activities. Lymphoedema cannot be cured but symptoms can effectively be improved by a comprehensive approach and the continuous use of compression therapy. An appropriate fitted compression garment is essential for compliance and thus a prerequisite for successful lymphoedema management. Compression garments with bulky seams are not only uncomfortable they also can lead to severe pressure marks or even reduce the mobility and function of the affected limb, which may negatively impact the already reduced QoL of lymphoedema patients...
