Silicon Nanowire Field-Effect Transistor as Label-Free Detection of Hepatitis B Virus Proteins with Opposite Net Charges.

The prevalence of hepatitis B virus (HBV) is a global healthcare threat, particularly chronic hepatitis B (CHB) that might lead to hepatocellular carcinoma (HCC) should not be neglected. Although many types of HBV diagnosis detection methods are available, some technical challenges, such as the high cost or lack of practical feasibility, need to be overcome. In this study, the polycrystalline silicon nanowire field-effect transistors (pSiNWFETs) were fabricated through commercial process technology and then chemically functionalized for sensing hepatitis B virus surface antigen (HBsAg) and hepatitis B virus X protein (HBx) at the femto-molar level.

Effect of Comprehensive Postural Instructions and Range of Motion Exercises Via Educational Videos on Motor Function and Shoulder Injury in Stroke Patients With Hemiplegia: A Preliminary Study.

Objective: The purpose of this study was to investigate the effect of comprehensive postural instructions and range of motion (ROM) exercises via educational videos for shoulder injury prevention and functional improvement of the hemiplegic shoulder after acute stroke.

Methods: In this prospective cohort study, 48 subacute stroke patients with hemiplegia were enrolled and divided into 2 groups (23 in experimental group and 25 in control group). In the control group (n = 25), the patients performed conventional rehabilitation for 5 days per week.

Effectiveness of ultrasound-guided vs direct approach corticosteroid injections for carpal tunnel syndrome: A double-blind randomized controlled trial.

Objective: To compare the outcomes of ultrasound-guided vs direct approach corticosteroid injection in patients with idiopathic carpal tunnel syndrome.

Methods: A double-blind randomized controlled study. Wrists affected by carpal tunnel syndrome were randomized to the ultrasound-guided (n = 22 wrists) or direct approach injection group (n = 17 wrists) before receiving 1 ml Betamethasone.

Dual displacement resolution encoder by integrating single holographic grating sensor and heterodyne interferometry.

A novel encoder with dual displacement resolution is developed by integrating a multiple-grating-scale holographic displacement sensor and a heterodyne interferometer. With suitable arrangement of the measurement system, two effective grating pitches (0.41 μm and 10.

The effect of home-based program and outpatient physical therapy in patients with head and neck cancer: A randomized, controlled trial.

Objectives: Physical therapy improves outcomes for patients with head and neck cancer (HNC) but home-based program (HBP) has not yet been investigated thoroughly. This study compared a HBP with outpatient physical therapy (OPT).

Methods: This trial categorized patients with primary HNC into OPT and HBP groups.

Tunneling-injection in vertical quasi-2D heterojunctions enabled efficient and adjustable optoelectronic conversion.

The advent of 2D materials integration has enabled novel heterojunctions where carrier transport proceeds thrsough different ultrathin layers. We here demonstrate the potential of such heterojunctions on a graphene/dielectric/semiconductor vertical stack that combines several enabling features for optoelectronic devices. Efficient and stable light emission was achieved through carrier tunneling from the graphene injector into prominent states of a luminescent material.

Highly Stretchable and Sensitive Photodetectors Based on Hybrid Graphene and Graphene Quantum Dots.

Stretchable devices possess great potential in a wide range of applications, such as biomedical and wearable gadgets and smart skin, which can be integrated with the human body. Because of their excellent flexibility, two-dimensional (2D) materials are expected to play an important role in the fabrication of stretchable devices. However, only a limited number of reports have been devoted to investigating stretchable devices based on 2D materials, and the stretchabilities were restricted in a very small strain.

Stretchable Random Lasers with Tunable Coherent Loops.

Stretchability represents a key feature for the emerging world of realistic applications in areas, including wearable gadgets, health monitors, and robotic skins. Many optical and electronic technologies that can respond to large strain deformations have been developed. Laser plays a very important role in our daily life since it was discovered, which is highly desirable for the development of stretchable devices.
