Fibro-Adipogenic Progenitor-Derived Pentraxin 3 Promotes Porcine Slow-Twitch Myofiber Formation by Suppressing the TLR4/TGFβ/SMAD2/3 Signaling Pathway

Abstract Skeletal muscle fiber-type composition is a critical factor influencing pork quality. However, the key proteins governing muscle fiber-type transformation remain largely unclear. Here, we define the secreted protein landscape underlying muscle fiber-type transformation r...

Extracellular Vesicle‐Encapsulated Small RNAs From Clostridium Butyricum Modulate Host Intestinal Lipid Metabolism

ABSTRACT The gut microbiota plays a critical role in regulating intestinal lipid metabolism, yet the mechanisms governing microbiota–host interactions during lipid uptake remain unclear. Here, we examined the relationship between fat digestibility and gut microbial composition, a...

Where does the eroded sediment from hillslopes go in small karst watersheds?

The transport mechanisms of eroded sediment in watersheds have long been a focal point and challenge in the field of eco-hydrology, especially in the context of increasingly frequent extreme climate events globally. However, few studies have focused on the hillslope to watershed...

Mechanisms of enhancing soil fertility without obviously elevating global warming potential under an optimal rice straw incorporation rate in a paddy soil

The utility of rice straw as an organic fertilizer has been widely recognized as a promising approach to enhancing soil fertility. However, straw return is currently in a dilemma, as it may also provoke greenhouse gas (GHG) emissions, leading to serious environmental consequences...

Aptamer-Based Sensing with Fluorescent Light-Up DNA

Abstract DNA aptamers are widely used in the construction of fluorescent sensors, typically employing labelled fluorophores as signaling indicators. However, this covalent labeling approach suffers from several limitations, including complex and costly chemical modification, inco...

Construction of composite biological soil crusts accelerates early-stage soil restoration in karst rocky desertification areas

Karst rocky desertification (KRD) represents one of the most severe forms of land degradation globally. Soils in these regions are characterized by structural instability, severe nutrient depletion, and fragmented microbial networks, all of which collectively impose formidable co...

Supplementation with Agrobacterium sp. FN01-Derived Crude Product Dominated by L-β-Galactoglucan Enhances Growth Performance and Nutrient Utilization and Modulates Intestinal Microbiota in Pigs

Polysaccharides are well known for their immunomodulatory properties and gut microbiota-regulating functions; however, their digestive stability and structure-dependent biological mechanisms remain poorly understood. This study investigated the in vitro enzymatic resistance and i...

Optimal standardized ileal digestible lysine levels in low-protein diets: Effects on performance of lactating sows and their offspring.

> 0.05). A nonlinear fitting of sensitive indicators with linear and quadratic effects was conducted to estimate optimal SID Lys requirements for lactating sow. Breakpoints for 14 d SUN, maximizing piglet benefits (weaning litter weight and individual weight), and sow BW loss wer...

Mannooligosaccharides modulate mucin O-glycan–gut microbe interactions and preserve the intestinal barrier in weaned piglets

Abstract Background The intestinal microbiota and mucosal barrier are closely intertwined, with mucin O-glycans playing a key role in maintaining intestinal homeostasis. However, how nutrition regulates mucin O-glycans remains poorly understood. This study investigated the regula...

Effects of Dietary Rumen-Undegradable Protein and Protein Levels on Growth Performance, Fermentation Parameters, Slaughter Performance, and Meat Quality on Fattening Hu Sheep

Optimizing protein nutrition in ruminants is vital for enhancing growth performance, meat quality, and overall production efficiency. However, the precise protein requirement for ruminants remains unclear. Two experimental trials were conducted to investigate the impact of varyin...
