Ischemic stroke and sarcopenia have an asymmetric bidirectional relationship based on a two-sample Mendelian randomization study.

Background: We investigated the potential relationship between age-related conditions, particularly sarcopenia and ischemic stroke (IS), through a two-sample Mendelian randomization (MR) study.

Methods: We conducted a two-sample bidirectional MR study to investigate the relationship between sarcopenia and stroke. Genetic instruments for sarcopenia were derived from the UK Biobank, while data on IS and its subtypes were obtained from the MEGASTROKE consortium.

Correlation of TyG-BMI and TyG-WC with severity and short-term outcome in new-onset acute ischemic stroke.

Objectives: To research the connection between the indexes of the indexes of triglyceride-glucose (TyG) combined with obesity indices and the initial neurological severity and short-term outcome of new-onset acute ischemic stroke.

Methods: Data of patients with acute ischemic stroke admitted to the Stroke Ward of the Affiliated Hospital of Beihua University from November 2021 to October 2023, were collected. The two indexes were calculated by combining TyG and obesity indices: TyG-body mass index (TyG-BMI) and TyG-waist circumference (TyG-WC).

Single-cell transcriptome and metagenome profiling reveals the genetic basis of rumen functions and convergent developmental patterns in ruminants.

The rumen undergoes developmental changes during maturation. To characterize this understudied dynamic process, we profiled single-cell transcriptomes of about 308,000 cells from the rumen tissues of sheep and goats at 17 time points. We built comprehensive transcriptome and metagenome atlases from early embryonic to rumination stages, and recapitulated histomorphometric and transcriptional features of the rumen, revealing key transitional signatures associated with the development of ruminal cells, microbiota, and core transcriptional regulatory networks.

Transcatheter Arterial Chemoembolization With Gelatin Sponge Microparticles Treated for BCLC Stage B Hepatocellular Carcinoma: A Single Center Retrospective Study.

Gelatin sponge particles are commonly used in the conventional transarterial chemoembolization (c-TACE) as an adjuvant embolizing agent for hepatocellular carcinoma (HCC). However, there are few reports regarding the clinical applications of gelatin sponge microparticles (GSMs) as a main embolizing agent in the treatment of HCC. This retrospective study aim to evaluate the efficacy and safety of patients with Barcelona Clinic Liver Cancer (BCLC) stage B HCC treated with intra-arterial injection of 350 to 560 μm GSMs mixed with anticancer agents.

HMGB1 Promotes Mitochondrial Dysfunction-Triggered Striatal Neurodegeneration via Autophagy and Apoptosis Activation.

Impairments in mitochondrial energy metabolism are thought to be involved in many neurodegenerative diseases. The mitochondrial inhibitor 3-nitropropionic acid (3-NP) induces striatal pathology mimicking neurodegeneration in vivo. Previous studies showed that 3-NP also triggered autophagy activation and apoptosis.

Anti-tumor and macrophage activation induced by alkali-extracted polysaccharide from Pleurotus ostreatus.

Pleurotus ostreatus is popularly consumed as traditional medicine and health food for enhancing immune function in China. Polysaccharides from mushroom have been demonstrated to possess a wide range of health beneficial properties. This study was carried out to elucidate the immunomodulating effects and molecular mechanism involved in the in vivo and in vitro anti-tumor activities of alkali-extracted polysaccharide (WPOP-N1) from the fruiting bodies of P.

Imprinting analysis of porcine DIO3 gene in two fetal stages and association analysis with carcass and meat quality traits.

Imprinted genes play important roles in mammalian growth, development and behavior. In this study, we obtained 1568 bp mRNA sequence of porcine DIO3 (deiodinase, iodothyronine, type III), and also identified its imprinting status during porcine fetal development. The complete open reading frame (ORF) encoding 278 amino acids.

The lecithin cholesterol acyltransferase gene (LCAT) plays an important role in lipoprotein metabolism, especially in the process termed 'reverse cholesterol transport'. In this study, we obtained the 1,434 bp mRNA sequence of porcine LCAT including the full coding region and encoding a protein of 472 amino acids. The sequence was deposited into the GenBank under the accession no.

Knockdown of endogenous SKIP gene enhanced insulin-induced glycogen synthesis signaling in differentiating C2C12 myoblasts.

PI(3,4,5)P(3) produced by the activated PI3-kinase is a key lipid second messenger in cell signaling downstream of insulin. Skeletal muscle and kidney-enriched inositol phosphatase (SKIP) identified as a 5'-inositol phosphatase that hydrolyzes PI(3,4,5) P(3) to PI(3,4)P(2), negatively regulates the insulin-induced glycogen synthesis in skeletal muscle. However the mechanism by which this occurs remains unclear.

Identification of a differentially expressed gene, ACL, between Meishan x Large White and Large White x Meishan F1 hybrids and their parents.

ATP-citrate lyase (ACL), one of the lipogenic enzymes, catalyses the formation of acetyl-coenzyme A (CoA) involved in the synthesis of fatty acid and cholesterol. In pig, very little is known about the ACL gene. In this work, the mRNA differential display technique was used to analyse the differences in gene expression between Meishan and Large White pigs and the F1 hybrids of both direct and reciprocal crosses.

Association of MYF5 and MYOD1 gene polymorphisms and meat quality traits in Large White x Meishan F2 pig populations.

MYF5 and MYOD1 belong to the myogenic regulatory factor (MRF) gene family. They code for the basic helix-loop-helix transcription factors that play key regulatory roles in the initiation and development of skeletal muscle and the maintenance of its phenotype. In this work three single nucleotide polymorphisms (SNPs) in porcine MYF5 and one in porcine MYOD1 were detected in three pig breeds (Large White, Landrace, and Meishan) by means of a PCR-RFLP protocol.

Using RNA interference to identify the different roles of SMAD2 and SMAD3 in NIH/3T3 fibroblast cells.

Smad proteins are principal intracellular signaling mediators of transforming growth factor beta (TGF-beta) that regulate a wide range of biological processes. However, the identities of Smad partners mediating TGF-beta signaling are not fully understood. We firstly examined the expression of Smad2 and Smad3 induced by TGF-beta 1 in normal NIH/3T3 cells.

Quantitative trait loci for carcass traits on pig chromosomes 4, 6, 7, 8 and 13.

For 22 carcass traits, we identified 16 QTLs (based on data for pig resource population no. 214, including 180 F2 hybrids of 3 Yorkshire boars and 8 Meishan sows) and mapped them with the use of 39 microsatellite marker loci on chromosomes 4, 6, 7, 8 and 13. Five QTLs were highly significant (P < or = 0.

NNAT and DIRAS3 genes are paternally expressed in pigs.

Although expression and epigenetic differences of imprinted genes have been extensively characterised in man and the mouse, little is known on livestock species. In this study, the polymorphism-based approach was used to detect the imprinting status of NNAT and DIRAS3 genes in five heterozygous pigs (based on SNP) of Large White and Meishan F(1) hybrids. The results show that both genes were paternally expressed in all the tested tissues (heart, liver, spleen, lung, kidney, stomach, small intestine, skeletal muscle, fat, uterus, ovary and pituitary).
