Genome-wide identification of the LEA gene family in Panax ginseng: Evidence for the role of PgLEA2-50 in plant abiotic stress response.

Ginseng frequently encounters environmental stress during its growth and development. Late Embryogenesis Abundant (LEA) proteins play a crucial role in combating adversity stress, particularly against abiotic challenges In this study, 107 LEA genes from ginseng, spanning eight subfamilies, were identified, demonstrating significant evolutionary conservation, with the LEA2 subfamily being most prominent. Gene duplication events, primarily segmental duplications, have played a major role in the expansion of the LEA gene family, which has undergone strong purifying selection.

Molecular analysis of the genes in and their responses to heat stress.

Background: is a perennial and semi-shady herb with tremendous medicinal value. Due to its unique botanical characteristics, ginseng is vulnerable to various abiotic factors during its growth and development, especially in high temperatures. Proteins encoded by genes form a highly conserved protein family that widely exists in eukaryotes.

Safety and efficacy of 0.02% and 0.01% atropine on controlling myopia progression: a 2-year clinical trial.

Four hundred myopic children randomly received atropine 0.02% (n = 138) or 0.01% (n = 142) in both eyes once-nightly or only wore single-vision spectacles (control group) (n = 120) for 2 years.

A Good Way to Reduce Screening for Retinopathy of Prematurity: Development of the ROP Model in a China Preterm Population.

Retinopathy of prematurity (ROP) is a preventable cause of blindness in children. Without treatment, more than 45% of eyes may suffer permanent vision loss. Current ROP screening guidelines, which include a range of birth weights (BWs) and gestational ages (GAs), may require screening many low-risk preemies who might develop severe ROP.

Effect of regulation of the NRG1/ErbB4 signaling pathway on the visual cortex synaptic plasticity of amblyopic adult rats.

This study aimed to investigate the effect of the neuregulin-1/epidermal growth factor 4 (NRG1/ErbB4) signaling pathway on visual cortex synaptic plasticity in adult amblyopic rats with monocular deprivation (MD). Compared with the control group, the P wave latency and amplitude of the MD group were prolonged and low, respectively, with reduced synaptic plasticity-related protein expression, lower number of visual cortex neurons, and increased apoptosis of visual cortex neurons. Recombinant neuregulin-1 (rNRG1) administration activated the NRG1/ErbB4 signaling pathway and improved the visual cortex synaptic plasticity in MD amblyopic rats.

microRNA-362-3p targets USP22 to retard retinoblastoma growth via reducing deubiquitination of LSD1.

Accumulating evidence has reported the role of microRNA (miR) in retinoblastoma (RB). Therefore, the objective was to discuss how miR-362-3p exerted its function in RB cell progression via regulating ubiquitin-specific protease 2 (USP22) and lysine-specific histone demethylase 1 (LSD1). MiR-362-3p, USP22 and LSD1 expression in RB cells and tissues were tested.

Effects of orthokeratology lens on axial length elongation in unilateral myopia and bilateral myopia with anisometropia children.

Purpose: To investigate the effect of orthokeratology (OK) lens on axial length (AL) elongation in unilateral myopia and bilateral myopia with anisometropia children.

Methods: Twenty-seven unilateral myopia (group 1) and 25 bilateral myopia with anisometropia children (group 2) were involved in this 1-year retrospective study. The eyes with higher spherical equivalent refractive error (SER) were assigned to the H eyes subgroup and the fellow eyes with lower SER to the L eyes subgroup in the two groups.

Comparison of botulinum toxin with surgery for the treatment of acute acquired comitant esotropia and its clinical characteristics.

We compared the therapeutic effects between botulinum toxin and surgery for acute acquired comitant esotropia (AACE) and analyze its clinical characteristics. The data of the 29 cases, who received treatment for AACE in the Ophthalmic Center of the First Affiliated Hospital of Zhengzhou University and Henan Provincial Ophthalmology Hospital between January 2016 and January 2017, were collected. The 29 cases with AACE were followed for 6 months or more, and received either botulinum toxin injection (group A with 13 cases) or squint correction (group B with 16 cases).

Protein kinase B (akt) promotes pathological angiogenesis in murine model of oxygen-induced retinopathy.

Akt, or protein kinase B, is an important signaling molecule that modulates many cellular processes such as cell growth, survival, and metabolism. However, the vivo roles and effectors of Akt in retinal angiogenesis are not explicitly clear. We therefore detected the expression of Akt using Western blotting or RT-PCR technologies in an animal model of oxygen-induced retinopathy, and investigated the effects of recombinant Akt on inhibiting vessels loss and Akt inhibitor on suppressing experimental retinal neovascularization in this model.

Effect of all-trans retinoic acid on the barrier function in human retinal pigment epithelial cells.

To investigate the effects of all-trans retinoic acid (atRA) on the barrier function in human retinal pigment epithelial cells, ARPE-19 cells were cultured on the filters as monolayer with atRA being added in the apical side. The change of epithelial permeability was observed from the measurement of transepithelial electrical resistance (TER), permeability assay, and Western Blot analysis. We discovered that atRA promoted the epithelial barrier function in vitro, and its bioavailability regulates the epithelial barrier, which is accompanied by altering expression of tight junctions (TJ)-associated proteins.
