Polysaccharides Attenuate Cardiac Injury by Inhibiting CaMKII-Mediated P38/NF-[Formula: see text]B/NLRP3 Signaling Pathway to Reduce Sepsis-Induced Apoptosis and Inflammation.

Sepsis is a life-threatening condition characterized by systemic inflammatory response syndrome, and often results in cardiac damage and poor prognosis. This study aimed to explore the protective effects of polysaccharides (PCP) on sepsis-induced cardiac injury and elucidate the underlying molecular mechanisms. An sepsis model was established, and an myocardial cell model was induced using lipopolysaccharide (LPS) to mimic a sepsis environment.

Catestatin alleviates PASMC phenotypic switching-mediated pulmonary arterial remodeling in a rat model of MCT-induced pulmonary arterial hypertension by promoting endothelium-derived no synthesis.

Background: Enhancing the nitric oxide (NO) signaling pathway is an effective strategy for treating pulmonary arterial hypertension (PAH). Previous research has found that Catestatin (CST) exerts a negative inotropic effect by upregulating NO production. However, the effect of CST on PAH remains unclear.

Mild Chronic Colitis Exacerbates Intracerebral Inflammation in Mice with Parkinson's Disease Through LRRK2-Mediated Regulation of NF-κB Activation and Inhibition of Nrf2.

Background And Objective: Inflammatory bowel disease (IBD) is a known risk factor for Parkinson's disease (PD). Leucine-rich repeat kinase 2 (LRRK2), a protein associated with both disease, regulates inflammation in the colon and brain. However, the precise mechanism by which LRRK2 mediates the crosstalk between intestinal inflammation and PD neuropathology remains unclear.

Condensed tannin ameliorates intestinal damage and mitochondrial dysfunction induced by high-fat diets in largemouth bass (Micropterus salmoides).

This study investigated the effects of condensed tannin (CT) supplementation on the intestinal health and mitochondrial function in largemouth bass (Micropterus salmoides) fed a high-fat diet. Six experimental diets were formulated, comprising three lipid levels in the diets (10 %, 15 %, and 20 %) with or without 3.75 g/kg CT supplementation.

From feed formulation to frozen flesh: Hydrolysable tannin mitigates high-fat diet-induced quality deterioration in flesh of largemouth bass (Micropterus salmoides) through enhancing antioxidant capacity, optimizing nutrient composition, and textural characteristics.

This study aimed to systematically evaluate the impact of adding hydrolysable tannin (HT, 1.25 g/kg) to a high-fat diet on the flesh quality of fish (Micropterus salmoides) after 12 weeks rearing. Results showed that high-fat diet supplemented with HT increased the content of crude protein and n-3 polyunsaturated fatty acids and optimized the amino acid composition of flesh.

Serinc2 antagonizes pressure overload-induced cardiac hypertrophy via regulating the amino acid/mTORC1 signaling pathway.

Background: Cardiac hypertrophy is characterized by the upregulation of fetal genes, increased protein synthesis, and enlargement of cardiac myocytes. The mechanistic target of rapamycin complex 1 (mTORC1), which responds to fluctuations in cellular nutrient and energy levels, plays a pivotal role in regulating protein synthesis and cellular growth. While attempts to inhibit mTORC1 activity, such as through the application of rapamycin and its analogs, have demonstrated limited efficacy, further investigation is warranted.

Condensed tannin improves growth and alleviates intestinal inflammation of juvenile largemouth bass (Micropterus salmoides) fed with high cottonseed protein concentrate diet.

The objective of this study was to examine the potential of condensed tannin (CT) in mitigating the adverse effects on growth and intestinal health induced by high cottonseed concentrate protein (CPC) diets in juvenile largemouth bass (Micropterus salmoides). Largemouth bass were respectively fed with the basic diet, the high CPC diet, and the CPC + CT diet (incorporated 3.75 g/kg CT into the high CPC diet) for a duration of 8 weeks.

Research on the Cell Wall Breaking and Subcritical Extraction of Astaxanthin from .

This study focused on developing an effective cell wall-breaking method for , followed by utilizing subcritical fluid extraction to isolate, extract, and concentrate astaxanthin from the complex fermentation products of . A comprehensive comparison of seven distinct methods for disrupting cell walls, including dimethyl sulfoxide treatment, lactic acid treatment, sodium hydroxide treatment, -glucanase enzymatic digestion, -mannanase enzymatic digestion, and a combined enzymatic treatment involving both -mannanase and -glucanase was conducted. The results identified the lactic acid method as the most effective in disrupting the cell walls of .

Efficient conversion of distillers grains as feed ingredient by synergy of probiotics and enzymes.

The direct feeding value of distillers grains is low due to the presence of higher cellulose, lignin and anti-nutritional factors such as mannan and xylan. In this study, complex enzymes and probiotic flora based on "probiotic enzyme synergy" technology were used to produce fermented distillers grains. The optimal substrate ratio, moisture content, fermentation time and temperature were determined.

Hydrolysable tannin improves growth performance and liver health of largemouth bass (Micropterus salmoides) fed high soybean meal diets.

This study provided evidence that the inclusion of hydrolysable tannin (HT) in high soybean meal (SBM) diets improved growth performance and glycolipid metabolism of largemouth bass (Micropterus salmoides). In vivo, various levels of HT were added to high SBM diets and fed to largemouth bass (initial weight: 6.00 ± 0.

Alterations of Myocardial Mitochondrial Morphology and Function in a Canine Model of Premature Ventricular Contractions-Induced Cardiomyopathy.

Aims: Changes in myocardial mitochondrial morphology and function in premature ventricular contractions (PVCs)-induced cardiomyopathy (PVCCM) remain poorly studied. Here, we investigated the effects of PVCs with different coupling intervals (CIs) on myocardial mitochondrial remodelling in a canine model of PVCCM.

Methods And Results: Twenty-one beagles underwent pacemaker implantation and were randomised into the sham (n = 7), short-coupled PVCs (SCP, n = 7), and long-coupled PVCs (LCP, n = 7) groups.

Exploiting synthetic biology platforms for enhanced biosynthesis of natural products in Yarrowia lipolytica.

With the rapid development of synthetic biology, researchers can design, modify, or even synthesize microorganisms de novo, and microorganisms endowed with unnatural functions can be considered "artificial life" and facilitate the development of functional products. Based on this concept, researchers can solve critical problems related to the insufficient supply of natural products, such as low yields, long production cycles, and cumbersome procedures. Due to its superior performance and unique physiological and biochemical characteristics, Yarrowia lipolytica is a favorable chassis cell used for green biomanufacturing by numerous researchers.

Serinc2 deficiency exacerbates sepsis-induced cardiomyopathy by enhancing necroptosis and apoptosis.

In critical care medicine, sepsis is a potentially fatal syndrome characterized by multi-organ dysfunction and eventual failure. Sepsis-induced cardiomyopathy (SIC) is characterized by decreased venstricular contractility. Serine incorporator 2 (Serinc2) is a protein involved in phosphatidylserine biosynthesis and membrane incorporation.

Effect of SH2B1 on glucose metabolism during pressure overload-induced cardiac hypertrophy and cardiac dysfunction.

This study mainly explored the effect and mechanism of Src homology 2 (SH2) B adaptor protein 1 (SH2B1) on cardiac glucose metabolism during pressure overload-induced cardiac hypertrophy and dysfunction. A pressure-overloaded cardiac hypertrophy model was constructed, and SH2B1-siRNA was injected through the tail vein. Haematoxylin and eosin (H&E) staining was used to detect myocardial morphology.
