Development and validation of a prediction model for heart failure in patients with heart valvular regurgitation.

Aims: Patients with heart valvular regurgitation is increasing; early screening of potential patients developing heart failure (HF) is crucial.

Methods: From 1 November 2019 to 31 October 2023, a total of 509 patients with heart valvular regurgitation hospitalized in the Department of Cardiovascular Disease of the First Affiliated Hospital of Guangzhou University of Traditional Medicine were enrolled. Three hundred fifty-six cases were selected as the training set for modelling, and 153 cases were selected as the validation set for the internal validation of the model.

Red meat consumption and risk for dyslipidaemia and inflammation: A systematic review and meta-analysis.

Aim: The study (PROSPERO: CRD42021240905) aims to reveal the relationships among red meat, serum lipids and inflammatory biomarkers.

Methods And Results: PubMed, EMBASE and the Cochrane databases were explored through December 2021 to identify 574 studies about red meat and serum lipids markers including total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), C-reactive protein (CRP) or hypersensitive-CRP (hs-CRP). Finally, 20 randomized controlled trials (RCTs) involving 1001 people were included, red meat and serum lipid markers and their relevant information was extracted.

A study on the enzymatic properties and reuse of cellulase immobilized with carbon nanotubes and sodium alginate.

Cellulase has many potential applications in ethanol production, extraction of medicinal ingredients, food, brewing, oil exploration, environmental protection. However, the widespread use of cellulase is limited by its relatively high production costs and low biological activity. Therefore, we studied the enzymatic properties and reusability of cellulase immobilized on multiwalled carbon nanotubes and sodium alginate for the first time.

Detection of bovine central nervous system tissue as bovine spongiform encephalopathy risk material by real-time reverse transcriptase-PCR in raw and cooked beef products.

There is increasing evidence of the association of the new variant of Creutzfeldt-Jacob disease (nvCJD) in humans with bovine spongiform encephalopathy (BSE) in cattle. Many countries established legislation of banning central nervous system (CNS) tissues, which are regarded as BSE-specified risk materials (SRM), in human food supply because of the potential transmission of BSE to humans. A real-time reverse transcriptase-PCR assay using the bovine glial fibrillary acidic protein (GFAP) mRNA template for the detection of CNS tissues in raw and cooked beef products was developed in this study.

[Detection of beef contaminated by bovine central nervous system tissue by enzyme immunoassay].

Objective: To study influencing factors of detection of bovine central nervous system (CNS) tissue contaminated beef by enzyme immunoassay (EIA), and the method was applied to the detection of imported beef and domestic beef of China.

Methods: Raw beef homogenates containing different concentrations of raw CNS tissue and the same samples which were heated were detected after different time by RIDASCREEN(r) Risk Material 10/5 and RIDASCREEN(r) Probennahme- zubehor Sampling tools kits. PBS suspension and sample dilution buffer (SDB) suspension of bovine brain tissue with the same concentration of the standard were detected.

Comparison study on clinical and neuropathological characteristics of hamsters inoculated with scrapie strain 263K in different challenging pathways.

Objective: To understand the infectious characteristics of a hamster-adapted scrapie strain 263K with five different routes of infection including intracerebral (i.c.), intraperitoneal (i.
