Effects of biotin and coated cobalamin on lactation performance, nutrient digestion and rumen fermentation in Holstein dairy cows.

Biotin (BI) and cobalamin (CA) are essential for rumen propionate production and hepatic gluconeogenesis. The study evaluated the influence of BI or/and coated CA (CCA) on milk performance and nutrient digestion in cows. Sixty Holstein dairy cows were assigned in a 2 × 2 factorial arrangement and randomised block design to four groups.

Effects of dietary folic acid supplementation on lactation performance and mammary epithelial cell development of dairy cows and its regulatory mechanism.

The experiment investigated the impacts of FA on the proliferation of bovine mammary gland epithelial cells (BMECs) and to investigate the underlying mechanisms. Supplementation of 10 µM FA elevated the mRNA expression of proliferating cell nuclear antigen (PCNA), cyclin A2 and cyclin D1, and protein expression of PCNA and Cyclin A1. The mRNA and protein expression of B-cell lymphoma-2 () and the to BCL2 associated X 4 () ratio elevated, while that of , Caspase-3 and Caspase-9 reduced by FA.

[Determination of complexation ability of rhubarb with copper ions by ultra-high performance liquid chromatography].

Gandou decoction (GDD) is a traditional Chinese medicine prescription that has been widely used to treat copper metabolism disorders in China with remarkable clinical effect and lower toxicity. However, evaluation of the complexation ability of copper ions is challenging, which hinders screening and discovery of coordinate active ingredients in GDD. An analytical method is needed to determinate the complexation ability of chemical constituents with copper ions.

Cell death-inducing DFFA-like effector C/CIDEC gene silencing alleviates diabetic cardiomyopathy via upregulating AMPKa phosphorylation.

Cell death-inducing DFFA-like effector C (CIDEC) is responsible for metabolic disturbance and insulin resistance, which are considered to be important triggers in the development of diabetic cardiomyopathy (DCM). To investigate whether CIDEC plays a critical role in DCM, DCM rat model was induced by a high-fat diet and a single injection of low-dose streptozotocin (27.5 mg/kg).

CIDEC silencing attenuates diabetic nephropathy via inhibiting apoptosis and promoting autophagy.

Objective: The role of cell death-inducing DFF45-like effector C (CIDEC) in insulin resistance has been established, and it is considered to be an important trigger factor for the progression of diabetic nephropathy (DN). We intend to explore whether CIDEC plays an important role in the regulation of DN and its potential mechanism.

Methods: High-fat diet and low dose streptozotocin were used to establish type 2 diabetic rat model.

Hepcidin gene silencing ameliorated inflammation and insulin resistance in adipose tissue of db/db mice via inhibiting METs formation.

As a major feature of diabetes, inflammation is closely related to macrophage extracellular traps and the expression of hepcidin upregulated by diabetes is reportedly involved in chronic inflammation. Therefore, we aimed to explore whether hepcidin could be implicated in inflammation and macrophage extracellular traps (METs) formation. The diabetic db/db mouse model was established exhibiting insulin resistance (IR), inflammation, macrophages infiltration and higher expression of hepcidin, where samples were obtained from epididymal adipose tissue.

Testosterone ameliorates vascular aging via the Gas6/Axl signaling pathway.

Low serum testosterone level is associated with aging-related vascular stiffness, but the underlying mechanism is unclear. The Growth arrest-specific protein 6 (Gas6) /Axl pathway has been proved to play important roles in cell senescence. In this study, we intend to explore whether Gas6/Axl is involved in the effect of testosterone on vascular aging amelioration.

Antitumor activity of ginsenoside Rd in gastric cancer via up-regulation of Caspase-3 and Caspase-9.

Ginsenoside Rd (GS-Rd), isolated from the Chinese traditional herbal medicine , is used for the treatment of cardiovascular diseases, inflammation, different body pains, and trauma. Caspase-3 and Caspase-9 belong to cysteine aspartic acid specific protease (Caspase) family that plays an important role in apoptosis progression of cancers. In the present study, we investigated the anti-tumor effect of GS-Rd by MTT assay, colony formation assessment, flow cytometry, and Western blotting.

Sarcopenia is attenuated by TRB3 knockout in aging mice via the alleviation of atrophy and fibrosis of skeletal muscles.

Background: Sarcopenia causes several adverse events in elderly people. Muscle fibre atrophy and interstitial fibrosis are the main histopathological changes in sarcopenia and account for decreased muscle function. Tribbles homologue 3 (TRB3) was previously reported to exhibit age-related expression and play a vital role in cell proliferation, differentiation, and fibrosis.

L-Carnitine inhibits the senescence-associated secretory phenotype of aging adipose tissue by JNK/p53 pathway.

Senescence-associated secretory phenotype (SASP) plays a role in aging adipose tissue dysfunction by directly promoting chronic inflammation. The JNK/p53 pathway was reported as a potential mechanism that mediates SASP. In this study, we investigated the effects of L-carnitine, an inhibitor of the JNK/p53 pathway in adipose tissue SASP and dysfunction.

[Knowledge, attitude and practice (KAP) of foodborne parasitic diseases among middle school students in Xuzhou City].

Objective: To investigate the status of knowledge, attitude and practice (KAP) of foodborne parasitic diseases among middle school students in Xuzhou City, so as to provide a reference to the health education.

Methods: A total of four middle schools were selected and their students were investigated with the basic information questionnaire and questions of foodborne parasitic diseases.

Results: The awareness rates of parasitic diseases, hazards and transmission were 56.

gen. nov., sp. nov., a haloalkalitolerant bacterium of the family isolated from a haloalkaline lake.

A novel haloalkalitolerant, rod-shaped bacterium, designated strain YIM 4-4, was isolated from the surface water of the Dugerno lake, a haloalkaline lake in Inner Mongolia. The taxonomy of strain YIM 4-4 was investigated by a polyphasic approach. Strain YIM 4-4 was Gram-stain-negative, strictly aerobic, non-motile and formed red colonies.

Identification of susceptibility genes in non-syndromic cleft lip with or without cleft palate using whole-exome sequencing.

Background: Non-syndromic cleft lip with or without cleft palate (NSCL/P) is among the most common congenital malformations. The etiology of NSCL/P remains poorly characterized owing to its complex genetic heterogeneity. The objective of this study was to identify genetic variants that increase susceptibility to NSCL/P.

A Case-control Study of Environmental Risk Factors for Nonsyndromic Cleft of the Lip and/or Palate in Xuzhou, China.

In this study, we sought to determine the association between environmental factors and nonsyndromic cleft of the lip and/or palate (NSCLP) to understand the etiology of the disease. A total of 200 NSCLP cases and 327 controls were recruited at the Maternal and Child Health Hospital of Xuzhou City. We conducted face-to-face interviews with the mothers of both cases and controls.

Anti-androgen effects of the pyrethroid pesticide cypermethrin on interactions of androgen receptor with corepressors.

To clarify whether the mechanism of androgen receptor (AR) antagonism of the pyrethroid pesticide cypermethrin associates with the interactions between the AR and corepressors silencing mediator for thyroid hormone receptors (SMRT) and nuclear receptor corepressor (NCoR), we have developed the mammalian two-hybrid assays. The AR N-terminal domain 1-660 amino acid residues were subcloned into the plasmid pVP16 to construct VP16-ARNTD. The C-terminal receptor interaction domains (RIDs) of SMRT and NCoR were used to construct pM-SMRT and pM-NCoR.

The pyrethroid insecticide, cypermethrin has been considered as an environmental anti-androgen by interfering with the androgen receptor (AR) transactivation. In order to clarify the effects of cypermethrin on the ligand-independent interaction between the AR and SRC-1, the mammalian two-hybrid assay has been developed in the study. The AR N-terminal domain 1-660 amino acid residues were subcloned into the plasmid pVP16 to construct the vector pVP16-ARNTD.
