DNAzyme-Based Dissipative DNA Strand Displacement for Constructing Temporal Logic Gates.

Toehold-mediated DNA strand displacement is the foundation of dynamic DNA nanotechnology, encompassing a wide range of tools with diverse functions, dynamics, and thermodynamic properties. However, a majority of these tools are limited to unidirectional reactions driven by thermodynamics. In response to the growing field of dissipative DNA nanotechnology, we present an approach: DNAzyme-based dissipative DNA strand displacement (D-DSD), which combines the principles of dynamic DNA nanotechnology and dissipative DNA nanotechnology.

Safety and efficacy of ultrasonography of tension after zone II flexor tendon repair: A randomized controlled trial.

Background: Primary flexor tendon repairs of lacerations in zone II of the hand are fraught with problems. Traditionally, exercise (active and passive), orthoses, and physical agents are common interventions for the rehabilitation of patients experiencing these issues. One area of focus in this field is how to safely utilize tension to lengthen gliding distance following zone II injury.

Research trends on digital flexor tendon: A bibliometric analysis based on CiteSpace.

Background: A host of experts have shown interest in the digital flexor tendon. However, few have conducted a bibliometric analysis of this field.

Purpose: This study aimed to carry out comprehensive and practical research on the academic status and the development trend in this area.

How to design high quality acupuncture trials-a consensus informed by evidence.

An international panel including patients, clinicians, researchers, acupuncture and surgery trialists, statisticians, and experts in clinical epidemiology and methodology have developed new guidance for randomised controlled trials in acupuncture. It addresses the most prevalent and critical concerns of current acupuncture trials and will help funding agencies, trial registers, and journal editors to evaluate the relevance, importance, and quality of submitted trial proposals and completed trials

Pivotal factors concerned in design of acupuncture clinical research: From two articles in JAMA.

Two randomized controlled trials of acupuncture concerning polycystic ovary syndrome (PCOS) and stress urinary incontinence (SUI) were published simultaneously in the 24th issue, 2017 of The Journal of the American Medical Association (JAMA). A trial involving PCOS indicated that active acupuncture did not increase live birth compared with sham acupuncture; meanwhile, another trial referring to SUI showed that electroacupuncture resulted in less urine leakage compared with sham electroacupuncture. With an eye to the negative and positive results of acupuncture, three pivotal factors should be contemplated: (1) proper illness for acupuncture, that is, a problem need to be solved in current medical science, and acupuncture may really work for it; (2) proper pre-studied primary outcome, which is better be objective and repeatedly measurable to reveal the therapeutic effect of acupuncture truly and objectively; (3) proper sham control, which can blind the patients to the upmost extent with minimal biological effects.

A High-Density Genetic Linkage Map for Cucumber (Cucumis sativus L.): Based on Specific Length Amplified Fragment (SLAF) Sequencing and QTL Analysis of Fruit Traits in Cucumber.

High-density genetic linkage map plays an important role in genome assembly and quantitative trait loci (QTL) fine mapping. Since the coming of next-generation sequencing, makes the structure of high-density linkage maps much more convenient and practical, which simplifies SNP discovery and high-throughput genotyping. In this research, a high-density linkage map of cucumber was structured using specific length amplified fragment sequencing, using 153 F2 populations of S1000 × S1002.

[Segmental meshing of brain tissues and simulation of soft tissue deformation].

Virtual surgery provides important assistance in preoperative planning of brain surgeries. A virtual surgery system essentially consists of visualization and modeling of the medical data and deformation simulation of human organs (mainly soft tissues). We used the hybrid level set theory, threshold segmentation, and morphological methods to segment the human head MRI volumetric data into five parts, namely the outline of the head, gray matter, white matter, cerebrospinal fluid and ventricles.
