In this study, we present a novel self-cleaning, photoresponsive membrane that is capable of removing pre-deposited foulant layers upon changes in surface morphology in response to UV or visible light irradiation while maintaining stable pore size and water permeance. These membranes were prepared by creating thin film composite (TFC) membranes by coating a porous support membrane with a thin layer of novel comb-shaped graft copolymers at two side-chain lengths featuring polyacrylonitrile (PAN) backbones and photoreactive side-chains, synthesized by atom transfer radical polymerization (ATRP)...

BACKGROUND: Functional recovery monitoring after total hip arthroplasty (THA) and total knee arthroplasty (TKA) is often limited to surgeon-based assessment and patient self-reporting rather than objective measures. However, traditional outcomes may not reliably gauge return of function. The goal of this study was to evaluate and compare an objective measure of postoperative recovery, daily step-count, with patient self-reported outcomes. METHODS: Prospectively, 589 patients used a mobile step-tracking application to record daily steps...

The popularity of capillary electrochromatography (CEC) has led to an increasing number of studies on the development and evaluation of enantioselective CEC systems. Herein, a novel, simple, and economical method for the preparation of chiral stationary phases for enantioselective open tubular capillary electrochromatography (OTCEC) was reported for the first time. This novel capillary column was fabricated through layer-by-layer self-assembly of GNPs on a 3-mercaptopropyl-trimethoxysilane (MPTMS)-modified fused-silica capillary and subsequent surface functionalization of the GNPs through self-assembly of thiols β-cyclodextrin (SH-β-CD)...

BACKGROUND: Family-focused practice (FFP) is an effective approach to supporting individuals with mental illness. 'Recovery' is also central to contemporary mental health care. However, there is a dearth of evidence about how the two concepts are related and subsequently implemented in practice. The aim of this study was to explore practitioners' understandings and practices of FFP within a recovery framework. METHODS: Purposive/snowball sampling was used to recruit and conduct qualitative interviews with 11 mental health practitioners in rural Australia...

BACKGROUND: Patients with myalgic encephalomyelitis / chronic fatigue syndrome (ME/CFS) are unable to activate brain-orchestrated endogenous analgesia (or descending inhibition) in response to exercise. This physiological impairment is currently regarded as one factor explaining post-exertional malaise in these patients. Autonomic dysfunction is also a feature of ME/CFS. OBJECTIVES: This study aims to examine the role of the autonomic nervous system in exercise-induced analgesia in healthy people and those with ME/CFS, by studying the recovery of autonomic parameters following aerobic exercise and the relation to changes in self-reported pain intensity...

Background: Despite the steadily escalating psychological and economic burden of depression, there is a lack of evidence for the effectiveness of available interventions on functioning areas beyond symptomatology. Therefore, the main objective of this study was to give an insight into the current measurement of treatment effectiveness in depression and to provide recommendations for its improvement. Materials and Methods: The study was based on a multi-informant approach, comparing data from a systematic literature review, an expert survey with representatives from clinical practice (130), and qualitative interviews with patients (11) experiencing depression...

The ability of the parasympathetic nervous system to flexibly adapt to changes in environmental context is thought to serve as a physiological indicator of self-regulatory capacity, and deficits in parasympathetic flexibility appear to characterize affective disorders such as depression. However, whether parasympathetic flexibility (vagal withdrawal to emotional or environmental challenges such as sadness, and vagal augmentation during recovery from sadness) could facilitate the effectiveness of adaptive affect regulation strategies is not known...

BACKGROUND: Spontaneous pneumomediastinum is defined as the presence of free air in the mediastinum without any apparent concomitant factors or disease. It is uncommon but usually benign and self-limiting. Generally, patients with spontaneous pneumomediastinum are admitted to hospital, and occasionally, prophylactic antibiotics are administered to prevent mediastinitis. The purpose of this study was to describe practices concerning the feasibility of outpatient treatment and follow-up of spontaneous pneumomediastinum and the necessity of prophylactic antibiotics...

Japan's earthquake, tsunami, and subsequent Fukushima nuclear power plant accident in March 2011 forced the evacuation of 185 000 residents. Psychological and social impacts exacerbated by long-term evacuation and widespread rumors have influenced residents' physical and mental health, despite the fact that no direct fatalities occurred from radiation exposure. However, during the 5 years following the accident, steady recovery in industrial and economic activity has lessened previously widespread, deeply rooted stigma and self-stigma among a significant number of affected victims...

Activatable photosensitizers that can be activated by cancer-associated stimuli have drawn increasing attention for simultaneous fluorescence imaging and photodynamic ablation of cancer cells. Here, we developed a cancer-cell specific photosensitizer nano-delivery system by synthesizing protoporphyrin IX (PpIX)-conjugated pullulan (P) with reducible disulfide bonds. The amphiphilic P-s-s-PpIX conjugate self-assembled in aqueous condition to form core-shell structured nanoparticles (P-s-s-PpIX NPs) with average size of 166nm, showing reduction-controllable stability...

Cortical neurons remap their receptive fields and rescale sensitivity to spared peripheral inputs following sensory nerve damage. To address how these plasticity processes are coordinated over the course of functional recovery, we tracked receptive field reorganization, spontaneous activity, and response gain from individual principal neurons in the adult mouse auditory cortex over a 50-day period surrounding either moderate or massive auditory nerve damage. We related the day-by-day recovery of sound processing to dynamic changes in the strength of intracortical inhibition from parvalbumin-expressing (PV) inhibitory neurons...

Fulminant myocarditis is a highly mortal syndrome. Meanwhile, the clinical course in surviving patients is generally self-limiting. This is a rare case of fulminant myocarditis with prolonged lymphocytic infiltration after hemodynamic recovery. A 64-year-old man was diagnosed with fulminant myocarditis and required intensive care with veno-arterial extracorporeal membrane oxygenation. Left ventricular function gradually improved but complete atrioventricular block (CAVB) persisted. Follow-up endomyocardial biopsies (EMBs) showed prolonged active infiltration of lymphocytes along with (18)F-FDG uptake in (18)F-FDG PET/CT until about 70 days after the onset...
