Phenotypic advantages and improved genomic stability following selection in advanced selfing-generations of Brassica allohexaploids.

Allopolyploids often exhibit advantages in vigor and adaptability compared to diploids. A long-term goal in the economically important Brassica genus has been to develop a new allohexaploid crop type (AABBCC) by combining different diploid and allotetraploid crop species. However, early-generation allohexaploids often face challenges like unstable meiosis and low fertility, and the phenotypic performance of these synthetic lines has rarely been assessed.

Factors influencing open gingival embrasures in orthodontic treatment: a retrospective clinical study.

Objective: This study aims to evaluate the incidence of open gingival embrasures (OGES) after orthodontic treatment and analyze its correlation with various clinical and radiographic parameters.

Methods: We retrospectively analyzed 330 orthodontic patients at West China Hospital of Stomatology from 2016 to 2023, categorizing them into Non-OGES (200) and OGES (130) groups based on post-treatment OGES presence in the central incisor area. Basic information of patients, pre- and post-treatment lateral cephalometric radiographs, and cone-beam computed tomography (CBCT) data were collected.

Genome-wide identification and characterization of transcription factors involved in defense responses against Sclerotinia sclerotiorum in Brassica juncea.

Sclerotinia sclerotiorum could cause significant yield losses of up to 70% in rapeseed cultivation. Nevertheless, the availability of immune or highly resistant germplasm and mechanisms to combat S. sclerotiorum, particularly in B.

Exploration of the molecular mechanism behind a novel natural genic male-sterile mutation of 1205A in Brassica napus.

The use of a male sterility hybrid seed production system has resulted in a significant increase in rapeseed yields by over 20%. Nevertheless, the mechanisms underlying male sterility remain largely unexamined. This study presents a spontaneous recessive genic male-sterile (RGMS) mutant of 1205A, which was employed to establish two two-line hybrid production systems: 1205AB and NT7G132AB.

Dynamics of chemical profile and microbial community in 3 consecutive years reveal Rhodococcus and Apiotrichum are potential microbes contributing to quality formation of Guang Chenpi.

Currently, there remains a debate regarding the functional microorganisms responsible for the quality formation of Guang Chenpi (GCP). Thus, the metabolite profiles and microbial diversity of GCP samples subjected to natural treatment versus those sterilized via electron beam irradiation were investigated over a three-year period. It was found the main constituents of GCP were influenced both by spontaneous changes and microbial activity.

Genetically and chemically intraspecific variations of Ficus hirta provide novel insights into its protection and utilization.

Background: Radix Fici Hirtae, the dry root of Ficus hirta, is a famous ethnomedicine and food that has been widely used by Yao and Zhuang nationalities in southern China for its potent antitumor, antifungal, and hepatoprotective effects. Recently, owing to over-exploitation and habitat destruction, F. hirta has been pushed to the brink of depletion.

Molecular and cellular morphology of placenta unveils new mechanisms of reproductive immunology.

Introduction: Despite of numerous studies of the placenta, some molecular and cellular characteristics, particularly the relationship among different cell types, have not been well understood. We aim to investigate the basic and intricate details of cellular and molecular elements in early and late phase placentas to gain better understanding of the immune regulation of human reproductive process.

Methods: A novel combination of techniques of spatial transcriptomics(ST), multiple immunohistochemistry, and a dual labeling combining immunohistochemistry and (fluorescence in situ hybridization) FISH on normal and ectopic pregnancy and animal models was employed to investigate the placenta at tissue, cell, protein and molecular levels and to trace the fetal and maternal origin of every cell in early and late placentas.

Triple circularly polarized luminescence of phenylalanine-based supramolecular gels regulated by kinetic and thermodynamic assembly pathways.

A single phenylalanine-based gelator can self-assemble into various chiral nanostructures with triple circularly polarized luminescence (CPL). Its supramolecular assembly and CPL emission are found to be dependent on the kinetic and thermodynamic pathways. This work provides new insight into the regulation of CPL-active functional materials.

Human iPSC-derived microglial cells protect neurons from neurodegeneration in long-term cultured adhesion brain organoids.

Brain organoid models have greatly facilitated our understanding of human brain development and disease. However, key brain cell types, such as microglia, are lacking in most brain organoid models. Because microglia have been shown to play important roles in brain development and pathologies, attempts have been made to add microglia to brain organoids through co-culture.

A Rare Q-Fever Infection Diagnosed Using Metagenomic Next-Generation Sequencing in Liver Transplantation Patient: A Case Report and Literature Review.

Q fever is a zoonotic disease caused by the Gram-negative bacterium , typically transmitted through exposure to infected animal secretions. As the clinical signs of Q-fever are largely non-specific in humans, a definitive diagnosis can often be overlooked, particularly when physicians fail to consider on the list of differentials. This case report describes Q-fever in a male patient who had previously undergone orthotopic liver transplantation.

Comprehensive review on neprilysin (NEP) inhibitors: design, structure-activity relationships, and clinical applications.

Neprilysin (NEP), a zinc-dependent membrane-bound metallopeptidase, regulates various bioactive peptides, particularly in kidneys, vascular endothelium, and the central nervous system. NEP's involvement in metabolizing natriuretic peptides, insulin, and enkephalins makes it a promising target for treating cardiovascular and Alzheimer's diseases. Several NEP inhibitors, such as sacubitril and omapatrilat, have been approved for clinical use, which inhibit NEP activity to prolong the bioactivity of beneficial peptides, thereby exerting therapeutic effects.

TAX1BP1 regulates the apoptosis of renal tubular epithelial cells in ischemia/reperfusion injury via the NF-kB/PMAIP1 signaling pathway.

Background: The pathogenesis of acute kidney injury (AKI) is not fully understood. Tax1-binding protein 1 (TAX1BP1) modulates inflammation and apoptosis through the NF-kB signaling pathway, however, its specific role in ischemic AKI remains unclear.

Methods: We injected a TAX1BP1 overexpression plasmid into the tail vein of male C57BL/6 mice, followed by clamping the bilateral renal arteries to induce AKI.

White circularly polarized luminescence from a dual-component emitter induced by FRET between tetraphenylene and PDI derivatives.

A chiral agent, TPE-ASP, incorporating aspartic acid as the chiral source and tetraphenylene derivatives as chromophores, was designed and synthesized. The chiral agent was self-assembled into regular spherical nanoparticles with a maximum luminescence asymmetry factor of |2.41 × 10| at 460 nm which is attributed to TPE-ASP.

Eimeria: Navigating complex intestinal ecosystems.

Eimeria is an intracellular obligate apicomplexan parasite that parasitizes the intestinal epithelial cells of livestock and poultry, exhibiting strong host and tissue tropism. Parasite-host interactions involve complex networks and vary as the parasites develop in the host. However, understanding the underlying mechanisms remains a challenge.

Molybdenum interferes with MMPs/TIMPs expression to reduce the receptivity of porcine endometrial epithelial cells.

To investigate the effect of trace element molybdenum (Mo) on the receptivity of porcine endometrial epithelial cells (PEECs) and evaluate Mo toxicity and its potential molecular mechanisms, Mo-treated PEECs models were established by incubating the cells with various concentrations of medium containing Mo (0, 0.005, 0.020, 0.
