In this work, we demonstrated a nano-decorated porous impedance electrode sensor for efficient capture, rapid killing and ultrasensitive detection of bacteria. The multi-functional sensor was prepared by a facile sonochemical method via in situ deposition of antibacterial prickly Zn-CuO nanoparticles and graphene oxide (GO) nanosheets on a Ni porous electrode. Due to the surface burr-like nanostructures, the nano-decorated impedance sensor exhibited very good bacterial-capture efficiency (70 - 80% in 20min) even at a low concentration of 50 CFU mL(-1), rapid antibacterial rate (100% killing in 30min) and high detection sensitivity (as low as 10 CFU mL(-1))...

The design and operation of ITER experimental fusion reactor requires the development of neutron measurement techniques and numerical tools to derive the fusion power and the radiation field in the device and in the surrounding areas. Nuclear analyses provide essential input to the conceptual design, optimisation, engineering and safety case in ITER and power plant studies. The required radiation transport calculations are extremely challenging because of the large physical extent of the reactor plant, the complexity of the geometry, and the combination of deep penetration and streaming paths...

The age of patients presenting with complex arrhythmias is increasing. Frailty is a multifaceted syndrome characterized by an increased vulnerability to stressors and a decreased ability to maintain homeostasis. The prevalence of frailty is associated with age. The aims of this European Heart Rhythm Association (EHRA) EP Wire survey were to evaluate the proportion of patients with frailty and its influence on the clinical management of arrhythmias. A total of 41 centres-members of the EHRA Electrophysiology Research Network-in 14 European countries completed the web-based questionnaire in June 2017...

Motivation: Sputum in the trachea is hard to expectorate and detect directly for the patients who are unconscious, especially those in Intensive Care Unit (ICU). Medical staff should always check the condition of sputum in the trachea. This is time-consuming and the necessary skills are difficult to acquire. Currently, there are few automatic approaches to serve as alternatives to this manual approach. Results: We develop an automatic approach to diagnose the condition of the sputum...

Nonsurgical vulvovaginal rejuvenation (NVR) is growing in popularity as a treatment for restoration of youthful female genitalia. Numerous radiofrequency (RF) and laser devices have entered the market claiming improvement in vaginal laxity and genitourinary syndrome of menopause. There is a paucity of evidence existing concerning the effectiveness of these devices for both pre- and postmenopausal women with laxity and/or atrophy at the histologic and clinical level. Therefore, the goal of this review is to scrutinize the peer-reviewed data on NVR with RF and laser devices, identify gaps in existing literature, and propose opportunities for further investigation...

Liquid crystal shells have attracted considerable attention in recent years. In such systems, a combination of confinement and curvature generates topological defect structures that do not exist in the bulk. Past studies, however, have largely focused on perfectly spherical shells, and little attention has been devoted to the impact of core geometry on the configuration and arrangement of topological defects. In this work, a microfluidic glass capillary device is used to encapsulate spherical and prolate ellipsoidal particles in nematic liquid crystal (LC) droplets dispersed in aqueous media...

BACKGROUND: Transpulmonary thermodilution (TPTD) is used to derive cardiac output CO, global end-diastolic volume GEDV and extravascular lung water EVLW. To facilitate interpretation of these data, several ratios have been developed, including pulmonary vascular permeability index (defined as EVLW/(0.25*GEDV)) and global ejection fraction ((4*stroke volume)/GEDV). PVPI and GEF have been associated to the aetiology of pulmonary oedema and systolic cardiac function, respectively. Several studies demonstrated that the use of femoral venous access results in a marked overestimation of GEDV...

Intertrochanteric femur fractures are common injuries associated with significant patient morbidity and mortality and high societal costs. Although intramedullary devices have shown promise for treating a wide range of intertrochanteric femur fractures, improper technique can lead to malalignment, fracture displacement and/or iatrogenic fractures. In particular, a "wedge effect" has been described, in which the passage of conical reamers and the intramedullary nail itself results in distraction of intertrochanteric fragments with lateralization of the shaft from the femoral neck and varus malalignment...

PURPOSE: Increased resting muscle sympathetic nerve activity (MSNA) and lower forearm blood flow (FBF) were observed in young men who use anabolic androgenic steroids (AAS). However, the response of MSNA and FBF in AAS users triggered by muscle mechanoreflex and central command has never been tested. Additionally, we evaluated the blood pressure (BP) and heart rate (HR) responses during these maneuvers. METHODS: Nineteen AAS users (AASU) aged 31±6 yr and 18 AAS nonusers (AASNU) aged 29±4 yr were recruited...

Treatment of unicoronal craniosynostosis is a surgically challenging problem, due to the involvement of coronal suture and cranial base, with complex asymmetries of the calvarium and orbit. Several techniques for correction have been described, including surgical bony remodeling, early strip craniotomy with orthotic helmet remodeling and distraction. Current distraction devices provide unidirectional forces and have had very limited success. Nitinol is a shape memory alloy that can be programmed to the shape of a patient-specific anatomy by means of thermal treatment...

Recently, arsenene a monolayer structure of the arsenic with two phases has semiconducting behavior. We have symmetrically investigated the electronic and optical properties of single-layer of arsenene with two types of functionalized organic molecules an electrophilic molecule [tetracyanoquinodimethane (TCNQ)] and a nucleophilic molecule [tetrathiafulvalene (TTF)], as an electron acceptor and electron donor, respectively. The interfacial charge transfer between arsenene monolayer and TCNQ/TTF molecules extensively reduces the band gap of arsenene and accordingly results in a p- or n-type semiconducting behavior, respectively...
