Multi-Omics Sequencing Dissects the Atlas of Seminal Plasma Exosomes from Semen Containing Low or High Rates of Sperm with Cytoplasmic Droplets.

Sperm cytoplasmic droplets (CDs) are remnants of cytoplasm that can cause a number of problems if it not shed from the sperm after ejaculation. Exosomes can rapidly bind to sperm, but it is not clear whether exosomes can affect the migration and shedding of CDs. We first extracted and characterized seminal plasma exosomes from boar semen containing sperm with low or high rates of CDs.

Alleviating heat stress-induced immune organ damage in ducks: Role of melittin.

Heat stress, one of the major challenges facing the global livestock industry, can adversely affect the immune system. The present study explored the mechanisms by which melittin alleviates heat stress-induced immune organ damage. Three hundred 20-day-old male Huainan sheldrakes were randomly assigned to four groups: heat stress group (basal diet), heat stress + melittin group (I, II, III group, basal diet + 0.

In-situ engineering of centralized mesopores and edge nitrogen for porous carbons toward zinc ion hybrid capacitors.

Porous carbons with large surface area (>3000 m/g) and heteroatom dopants have shown great promise as electrode materials for zinc ion hybrid capacitors. Centralized mesopores are effective to accelerate kinetics, and edge nitrogen can efficiently enhance pseudocapacitive capability. It is a great challenge to engineer centralized mesopores and edge nitrogen in large-surface-area porous carbons.

A SYBR green I-based multiplex real-time PCR for simultaneous detection of pseudorabies virus, porcine circovirus 3 and porcine parvovirus.

Background: Pseudorabies virus (PRV), porcine parvovirus (PPV) and porcine circovirus 3 (PCV3) are common in swine farms in China. Single infection or co-infection with PRV, PPV and/or PCV3 was difficult to distinguish between their clinical symptoms and pathological changes. Therefore, a quick and accurate detection method is needed for epidemiological surveillance, disease management, import and export control.

Enhanced tetracycline degradation using carbonized PEI-grafted lignin microspheres supported Fe-loading catalyst across a wide pH range in Fenton-like reactions.

Traditional homogeneous Fenton systems face limitations, including a narrow pH range, potential secondary pollution, and poor repeatability. In this study, these bottlenecks in tetracycline wastewater treatment were addressed with using carbonized porous polyethyleneimine-grafted lignin microspheres (PLMs) supported Fe-loading catalysts (PLMs/Fe-C). An optimized PLMs/Fe-C catalyst under specific conditions (carbonization temperature: 350 °C, PLMs: Fe = 1:1, and alkali lignin: PEI = 1:4) was developed, which proved to be an efficient Fenton-like catalyst for tetracycline (TC) degradation.

Prediction and analysis of the tumor invasiveness of pulmonary ground-glass nodules based on metabolomics.

In recent years, the incidence of ground-glass nodular lung adenocarcinoma has gradually increased. Preoperative evaluation of the tumor invasiveness is very important, but there is a lack of effective methods. Plasma samples of ground-glass nodular lung adenocarcinoma and healthy volunteers were collected.

Thermoresponsive lignin-based polyelectrolyte complexes for the preparation of spherical nanoparticles: Application in pesticide encapsulation.

Lignin-based nanoparticles hold tremendous potential for various applications. This study proposes an innovative and straightforward method for the synthesis of spherical hybrid lignin nanoparticles (hy-LNPs) with a tunable pore structure. The approach involves blending lignin with 20 wt% polyamide-epichlorohydrin, resulting in the formation of thermoresponsive lignin-based polyelectrolyte complexes.

The influence of host genotype and gut microbial interactions on feed efficiency traits in pigs.

Feed efficiency and growth performance are economically important traits in pigs. Precious studies have been revealed that both genetics and gut microbes could influence host phenotypes, however, the mechanisms by which they affect pig growth and feed efficiency remain poorly understood. In this study, 361 crossbred Duroc × (Landrace × Yorkshire) commercial pigs were genotyped using GeneSeek Porcine SNP50K BeadChip, and the microbiotas from fecal samples were acquired using microbial 16S rRNA gene sequencing technology to investigate the impact of host genetics and gut microorganisms on growth and feed efficiency.

Occurrence and Genotypic Identification of spp. and in Bamaxiang Pigs in Bama Yao Autonomous County of Guangxi Province, China.

spp. and are common intestinal pathogens capable of infecting both humans and animals, which lead to severe diarrhea and other intestinal diseases, posing a threat to public health. The Bamaxiang pig, a specialty of Bama Yao Autonomous County in Guangxi Province, China, is an important local breed in the regional pork market and an excellent model animal for biomedical research.

Nearly 30a shrub introduction in desert steppes has led to an increase in saprotrophic fungi, accelerating the degradation of carbon compounds and nitrate reduction.

Clarifying how soil microbial communities respond to shrub introduction after overgrazing in desert steppe and their potential functions is crucial for understanding the biogeochemical processes involved in vegetation transformation and sustainability of desert grasslands. However, the dynamics of microbial communities remain poorly understood. We selected enclosed grasslands (20a), overgrazed grasslands, and shrublands (6a, 15a, and 25a) to explore how shrubs introduced influence soil microbial structure and functional groups over the long term after desert grassland degradation.

Acrylate-Based PEG Hydrogels with Ultrafast Biodegradability for 3D Cell Culture.

Poly(ethylene glycol) (PEG)-based hydrogels are particularly challenging to degrade, which hinders efficient cell harvesting within the gel matrix. Here, highly branched copolymers of PEG methyl ether acrylate (PEGMA) and disulfide diacrylate (DSDA) (PEG-DS) with short primary chains and multiple pendent vinyl groups were synthesized by a "vinyl oligomer combination" approach. PEG-DS readily cross-links with thiolated gelatin (Gel-SH) to form hydrogels.

DDX5 deficiency drives non-canonical NF-κB activation and NRF2 expression, influencing sorafenib response and hepatocellular carcinoma progression.

In advanced hepatocellular carcinoma (HCC), RNA helicase DDX5 regulates the Wnt/β-catenin-ferroptosis axis, influencing the efficacy of the multi-tyrosine kinase inhibitor (mTKI) sorafenib. DDX5 inhibits Wnt/β-catenin signaling, preventing sorafenib-induced ferroptosis escape. Sorafenib/mTKIs reduce DDX5 expression, correlating with poor patient survival post-sorafenib treatment.

Structural changes and grading mechanism of lignin during solid alkali-active oxygen extraction and grading.
