#1
Sun Yihan, Liu Mingming, Zhiguang Guo
Herein, a catalytic mesh with unique wettability, high oil-water separation efficiency and excellent catalytic performance towards aromatic dyes was fabricated. Polypyrrole (PPy) was firstly pre-coated on pristine stainless-steel mesh (SSM) surface via cyclic voltammetry approach. Subsequently, a simple electrodeposition process was performed to prepare and anchor Ag nanoparticles (AgNPs) onto the PPy-coated SSM surface. The PPy-coated mesh with anchored AgNPs was denoted as PPy/AgNPs-coated SSM. The obtained PPy/AgNPs-coated SSM exhibited dual superlyophobic properties and were able to achieve on-demand separation to deal with various of light oil (ρoil  < ρwater ) and heavy oil (ρoil  > ρwater )-water mixtures...

California faces significant energy and water infrastructure planning challenges in response to a changing climate. Immediately following the most severe recorded drought, the state experienced one of its wettest water years in recorded history. Despite the recent severe wet weather, much of the state's critical groundwater systems have not recovered from the drought. The recent Sustainable Groundwater Management Act (SGMA) aims to eliminate future depletion risks, but may force California basins to seek alternative water sources by limiting groundwater withdrawals during droughts...

Surgical resection of the esophagus requires sacrificing a long portion of it. Its replacement by the demanding gastric pull-up or colonic interposition techniques may be avoided by using short biologic scaffolds composed of decellularized matrix (DM). The aim of this study was to prepare, characterize, and assess the in vivo remodeling of DM and its clinical impact in a preclinical model. A dynamic chemical and enzymatic decellularization protocol of porcine esophagus was set up and optimized. The resulting DM was mechanically and biologically characterized by DNA quantification, histology, and histomorphometry techniques...

Releasing greenhouse gases into the atmosphere because of widespread use of fossil fuels by humankind has resulted in raising the earth's temperature during the past few decades. Known as global warming, increasing the earth's temperature may in turn endanger civilization on the earth by starting a cycle of environmental changes including climate change and sea level rise. Therefore, replacing fossil fuels with more sustainable energy resources has been considered as one of the main strategies to tackle the global warming crisis...

The purpose of this study was to describe the mechanical characteristics of a trampoline circus act and its individual tracks performed in training and shows using a tri-axial accelerometer. A track is an artist's specific role within a choreographed act. Seven male acrobats performed their trampoline act during training and shows while wearing a triaxial accelerometer and reported ratings of perceived exertion (RPE) after each trial. Average acceleration (AVG), root mean square (RMS), root mean to the fourth (RM4), time spent in specific acceleration ranges and RPE were measured/recorded from training and show acts...

As the most consumed shrimp variety, white-leg shrimp (Litopenaeus vannamei) owns a high market demand in Korea. This study sought to screen the frozen white-leg shrimp for Aeromonas spp. harboring antimicrobial and heavy metal resistance characteristics. A total of 44 Aeromonas spp. strains were isolated and tested for antibiotic susceptibility and heavy metal tolerance followed by PCR-based detection of resistance genes and integrons. It was observed that resistance to ampicillin and oxacillin was 100% among isolates...

It is well established that test anxiety is negatively related to examination performance. Based on attentional control theory, the aim of this study was to examine whether increased effort can protect against performance debilitating test anxiety. Four hundred and sixty-six participants (male = 228; 48.9%; White = 346, 74.3%; mean age = 15.7 years) completed self-report measures of test anxiety and effort that were matched to performance on a high-stakes secondary school examination. The worry and bodily symptoms components of test anxiety were negatively, and effort, positively related to examination performance...

Psychologists have studied small-group and team effectiveness for decades, and although there has been considerable progress, there remain significant challenges. Meta-analyses and systematic research have provided solid evidence for core team cognitive, motivational, affective, and behavioral processes that contribute to team effectiveness and empirical support for interventions that enhance team processes (e.g., team design, composition, training, and leadership); there has been substantial evidence for a science of team effectiveness...

Major emergencies are extreme team decision making environments. They are complex, dynamic, high-stakes and fast paced events, wherein successful resolution is contingent upon effective teamwork. Not only do emergency teams coordinate at the intrateam level (e.g., police team), but they are increasingly required to operate at the interteam level (e.g., police, fire and ambulance teams). This is in response to the desire for networked and cost-effective practice and due to the evolving nature of modern threats, such as extreme weather events and terrorist attacks, which require a multi- rather than single-agency response...

Few industries match the scale of health care. In the United States alone, an estimated 85% of the population has at least 1 health care encounter annually and at least one quarter of these people experience 4 to 9 encounters annually. A single visit requires collaboration among a multidisciplinary group of clinicians, administrative staff, patients, and their loved ones. Multiple visits often occur across different clinicians working in different organizations. Ineffective care coordination and the underlying suboptimal teamwork processes are a public health issue...

Ebola virus (EBOV) disease is a complex zoonosis that is highly virulent in humans, and has caused many deaths. Highly sensitive detection of EBOV is of great importance to early-stage diagnosis for increasing the probability of survival. Herein, we established a cellular beacon-mediated counting strategy for ultrasensitive EBOV assay on a micromagnetic platform. The detection platform that was assisted by on-demand magnetic field manipulation showed high integration, and enhanced complex sample pretreatment ability by magnetophoretic separation and continuous flow washing...

BACKGROUND: Multiple sclerosis (MS) is a non-curable chronic inflammatory disease of the central nervous system that affects more than 2 million people worldwide. MS-related symptoms impact negatively on the quality of life of persons with MS, who need to be active in the management of their health. mHealth apps could support these patient groups by offering useful tools, providing reliable information, and monitoring symptoms. A previous study from this group identified needs, barriers, and facilitators for the use of mHealth solutions among persons with MS...

Trunk postural control (TPC) has been investigated in several populations and tasks. Previous work observed targeted training of TPC via isolated trunk control tasks may improve performance in other activities (e.g., walking). However, the nature of this relationship remains unknown. We therefore investigated the relationship between TPC, at both the global (i.e., response to finite perturbations) and local (i.e., resistance to continuous perturbations) levels, during walking and unstable sitting, both at varying levels of task demand...

The emergence of designer drugs as substances of abuse has seen a dramatic increase over the last few years. Customs officials are responsible for the control of products entering the European Union (EU) market. This control applies to chemicals in general, pharmaceutical products and medicines. Numerous products imported from non-EU countries, often -declared as 'bath salts' or 'fertilizers', may in fact contain new psychoactive substance (NPS). These are not necessarily controlled under international law, but are subject to monitoring in agreement with EU legislation...

Epilepsy is a complex neurological disease characterized by spontaneous episodes of abnormal, simultaneous firing of a neuronal population and disturbances of consciousness (so-called seizures) of unknown cause. Antiepileptic drugs are only symptomatic treatment, and there is a strong demand for the search of an alternative treatment of epilepsy. For this purpose, animal models of epilepsy are an important prerequisite. There are various animal models with chronic brain dysfunctions thought to reflect the processes underlying human epilepsy...

Climbers often train on indoor climbing walls, which are modifiable to simulate features of outdoor climbing environments at different levels of difficulty. The aim of this study was to evaluate the influence of regularity of climbing holds on emergent perceptual-motor behaviours. Skilled climbers performed six repetitions of two topographically similar routes on an indoor climbing wall. One route was composed of 18 different types of hand holds (irregular route), whereas the other route had only two types of hand holds (regular route)...

According to the United Nations Refugee Agency (UNHCR), 65.6 million people have been forcibly displaced worldwide. Several factors have a major influence on asylum seekers' health; so, their health profile is markedly different from that of the population in the country of asylum. The aim of this study is to review the major issues physicians need to be aware of when treating asylum seekers, with a special focus on the neurological problems of asylum seekers and refugees. The major impact factors on refugees' health are linked to experiences and exposure (1) in the country of origin, (2) in refugee camps and en route to Europe, and (3) in the process of immigration into the host country and living in European asylum centers...
