Bidirectional multi-beam with multi-polarizations tensor holographic metasurface using bilayer anisotropic elements.

In this paper, we present and design a tensor holographic metasurface (THMS) capable of radiating multiple beams with different polarizations in both forward and backward directions. The proposed THMS manipulates the fundamental TE mode surface waves (SWs) to produce bidirectional leaky-wave radiation using bilayer anisotropic metal patches. To achieve the independent control of the direction and polarization of bidirectional beams, the nature of the capacitive impedance element supporting TE mode SWs is exploited.

Using RNA-Seq Analysis to Select Key Genes Related to Seed Dormancy in ALS-Inhibiting Resistant with Pro-197-Thr Mutation.

In the present study, a resistant population with a Pro-197-Thr mutation of acetolactate synthetase (ALS) was found to have a resistance index of 457.

Diverse ALS mutations and cross-and multiple-resistance to ALS and EPSPS inhibitors in flucarbazone‑sodium-resistant Bromus japonicus populations from Hebei province, China.

Japanese brome (Bromus japonicus) has become one of the main weeds in wheat fields in Hebei province of China and causes a large decrease of wheat production. A total of 44 putative resistant and 2 susceptible Japanese brome populations were collected in the 2021/2022 crop season from Hebei province of China to determine resistance levels to flucarbazone‑sodium and to investigate the diversity of acetolactate synthase (ALS) mutations, as well as to confirm the cross-and multiple-resistance levels to ALS and EPSPS (5-enolpyruvate shikimate-3-phosphate synthetase) inhibitors. Whole plant bioassay results showed that 15 out of 44 populations tested or 34% were resistant to flucarbazone‑sodium.

Cholesterol metabolism: physiological regulation and diseases.

Cholesterol homeostasis is crucial for cellular and systemic function. The disorder of cholesterol metabolism not only accelerates the onset of cardiovascular disease (CVD) but is also the fundamental cause of other ailments. The regulation of cholesterol metabolism in the human is an extremely complex process.

Cataract-related variant R114C increases βA3-crystallin susceptibility to environmental stresses by disrupting the protein senior structure.

Congenital cataract is a major cause of childhood blindness worldwide, with crystallin mutations accounting for over 40 % of gene-mutation-related cases. Our research focused on a novel R114C mutation in a Chinese family, resulting in bilateral coronary cataract with blue punctate opacity. Spectroscopic experiments revealed that βA3-R114C significantly altered the senior structure, exhibiting aggregation, and reduced solubility at physiological temperature.

Kaempferol ameliorated alcoholic liver disease through inhibiting hepatic bile acid synthesis by targeting intestinal FXR-FGF15 signaling.

Background: Alcoholic liver disease (ALD) is characterized by the disturbance of bile acids homeostasis, which further deteriorates ALD. Bile acid metabolism and its related signal molecules have become new therapeutic targets for alcoholic liver disease. This study aimed to investigate the impact of kaempferol (KAE) on ALD and elucidate its underlying mechanisms.

Non-typical persistent hyperplastic primary vitreous: a rare case report and review of the literature.

Background: Persistent hyperplastic primary vitreous (PHPV), also known as persistent fetal vasculature (PFV), is a clinical entity that traditionally presents with leukocoria, microphthalmia, retinal dysplasia, or eyeball shrinkage which is associated with poor vision. However, there is a dearth of literature on cases of PHPV in adulthood or with asymptomatic occurrence. This report presents the clinical and pathological findings of a non-typical PHPV case and discuss the current knowledge for this condition.

Insight into Pathogenic Mechanism Underlying the Hereditary Cataract Caused by βB2-G149V Mutation.

Congenital cataracts account for approximately 5-20% of childhood blindness worldwide and 22-30% of childhood blindness in developing countries. Genetic disorders are the primary cause of congenital cataracts. In this work, we investigated the underlying molecular mechanism of G149V point missense mutation in βB2-crystallin, which was first identified in a three-generation Chinese family with two affected members diagnosed with congenital cataracts.

Thioredoxin-1 regulates the autophagy induced by oxidative stress through LC3-II in human lens epithelial cells.

Oxidative stress plays a major role in age-related cataract development. The cellular antioxidant protein thioredoxin-1 (Trx-1) and its negative regulator, thioredoxin binding protein-2 (TBP-2), are pivotal in the cellular redox balance during oxidative stress. The aim of this study is to investigate the effect of Trx-1 and TBP-2 on LC3 I/LC3 II in oxidative stress-induced autophagy in human lens epithelial cells (LECs).

The Prediction Models for High-Risk Population of Stroke Based on Logistic Regressive Analysis and Lightgbm Algorithm Separately.

Background: We aimed to investigate the high-risk factors of stroke through logistic regressive analysis and using LightGBM algorithm separately. The results of the two models were compared for instructing the prevention of stroke.

Methods: Samples of residents older than 40 years of age were collected from two medical examination centers in Jiaxing, China from 2018 to 2019.

Noncoding RNAs in cataract formation: Star molecules emerge in an endless stream.

For decades, research on the pathological mechanism of cataracts has usually focused on the abnormal protein changes caused by a series of risk factors. However, an entire class of molecules, termed non-coding RNA (ncRNA), was discovered in recent years and proven to be heavily involved in cataract formation. Recent studies have recognized the key regulatory roles of ncRNAs in cataracts by shaping cellular activities such as proliferation, apoptosis, migration and epithelial-mesenchymal transition (EMT).

Research Progress Concerning a Novel Intraocular Lens for the Prevention of Posterior Capsular Opacification.

Posterior capsular opacification (PCO) is the most common complication resulting from cataract surgery and limits the long-term postoperative visual outcome. Using Nd:YAG laser-assisted posterior capsulotomy for the clinical treatment of symptomatic PCO increases the risks of complications, such as glaucoma, retinal diseases, uveitis, and intraocular lens (IOL) pitting. Therefore, finding how to prevent PCO development is the subject of active investigations.

Thin film nanoarchitectonics of layer-by-layer assembly with reduced graphene oxide on intraocular lens for photothermal therapy of posterior capsular opacification.

Due to development of surgical techniques and intraocular lens (IOL) implants, vision can often be restored in cataracts patients. However, posterior capsular opacification (PCO) has become the most common and challenging complication in cataracts surgery. While various approaches such as surface modification and drug prophylaxis have been investigated to prevent PCO development, there is no standard treatment that is sufficiently safe and effective to meet clinical demands.

Selection of relatively exact reference genes for gene expression studies in flixweed (Descurainia sophia) by quantitative real-time polymerase chain reaction.

The reliable gene expression analysis of a reverse transcription quantitative polymerase chain reaction (qRT-PCR) mainly depends on selecting suitable reference genes that can express stably under different experimental conditions. Thus far, no reference genes have been identified in flixweed. In this paper, 7 supposed reference genes were selected to evaluate their expression stabilities by qRT-PCR in flixweed under three conditions including different sampling times after tribenuron treatment, different organs, and different growth stages using geNorm, NormFinder, and BestKeeper statistical algorithms.
