Breeding by Design for Functional Rice with Genome Editing Technologies.

The conventional approaches to crop breeding, which rely predominantly on time-consuming and labor-intensive methods such as traditional hybridization and mutation breeding, face challenges in efficiently introducing targeted traits and generating diverse plant populations. Conversely, the emergence of genome editing technologies has ushered in a paradigm shift, enabling the precise and expedited manipulation of plant genomes to intentionally introduce desired characteristics. One of the most widespread editing tools is the CRISPR/Cas system, which has been used by researchers to study important biology-related problems.

Innocuous solvent-based, low-temperature curable, and highly transparent photosensitive polyimides developed using soluble polyimides containing bio-based magnolol moieties.

Traditional photosensitive polyimide (PSPI) materials require a high curing temperature and exhibit low transparency, limiting their applications in thermally sensitive optical devices. To overcome this challenge, soluble photosensitive polyimide resins were synthesized based on the structural design of a bio-based magnolol monomer. It is noteworthy that the PI photoresist, developed by using the as-prepared polyimides and non-toxic solvents (2-acetoxy-1-methoxypropane, PGEMA) and other additives, demonstrated an impressive low-temperature curing performance (180 °C).

Synergistic high-entropy phosphides with phosphorus vacancies as robust bifunctional catalysts for efficient water splitting.

High-entropy phosphides (HEPs) have garnered increasing interest as innovative electrocatalysts for water splitting, highlighted by their distinctive catalytic activity, elemental synergy, and tunable electronic configuration. Herein, a novel electrode comprising CoNiCuZnFeP nanocubes with rich phosphorus vacancies was fabricated through coprecipitation and phosphorization two-step method. The synergistic interaction among metal elements and the modulation of the electronic configuration by phosphorus vacancies augmentation enhance the catalytic performance for both the oxygen evolution reaction (OER) and hydrogen evolution reaction (HER).

Central venous pressure as a method of optimising atrio-ventricular delay after cardiac surgery.

Introduction: Haemodynamic atrioventricular delay (AVD) optimisation has primarily focussed on signals that are not easy to acquire from a pacing system itself, such as invasive left ventricular catheterisation or arterial blood pressure (ABP). In this study, standard clinical central venous pressure (CVP) signals are tested as a potential alternative.

Methods: Sixteen patients with a temporary pacemaker after cardiac surgery were studied.

Measurement of lacrimal gland tissue stiffness for the diagnosis of visual display terminal-associated dry eye disease using shear wave elastography.

Objective: This study aimed to evaluate whether lacrimal gland tissue stiffness can aid in diagnosing dry eye disease (DED) using shear wave elastography (SWE). We also aimed to assess the correlation between the subjective symptoms of ocular strain, SWE values, and other ocular examination findings (Schirmer's test and tear film breakup time [TBUT]) contributing to the diagnosis of DED.

Methods: This cross-sectional study recruited 300 participants who were engaged in video display terminal (VDT) work and had been diagnosed with DED by an ophthalmologist for more than one year, and 100 healthy participants without DED symptoms, from August 2020 to December 2021.
