Genetic Parameters for Age at First Calving and First Calving Interval of Beef Cattle.

Animals (Basel)

Department of Genetics and Breeding of Farm Animals, Institute of Animal Science, 104 01 Prague, Czech Republic.

Published: November 2020

The objective of this study was to estimate genetic parameters for age at first calving (AFC) and first calving interval (FCI) for the entire beef cattle population and separately for the Charolais (CH) and Aberdeen Angus (AA) breeds in the Czech Republic. The database of performance testing between the years 1991 and 2019 was used. The total number of cows was 83,788 from 11 breeds. After editing, the data set contained 33,533 cows, including 9321 and 4419 CH and AA cows, respectively. The relationship matrix included 85,842 animals for the entire beef population and 24,248 and 11,406 animals for the CH and AA breeds, respectively. A multibreed multitrait animal model was applied. The estimated heritability was low to moderate. Genetic correlations between AFC and FCI varied depending on the breeds from positive to negative. Differences between variance components suggest that differences between breeds should be considered before selection and breeding strategy should be developed within a breed.

Ensuring boar sperm quality before insemination is crucial for maximizing field fertility and efficient pig production. The computer-assisted sperm analysis (CASA) and fluorescence probes combined with flow cytometry (FC) are commonly used techniques for evaluating sperm kinematics and functions, closely related to animal fertility. However, their high cost and complex operations make it challenging to apply them in laboratories or pig breeding farms with limited resources.

Insulin Resistance Mediates the Association Between Vitamin D and Non-Alcoholic Fatty Liver Disease.

Int J Prev Med

December 2024

Department of Endocrinology, Xuzhou Central Hospital, Xuzhou Clinical School of Xuzhou Medical University, Affiliated Hospital of Southeast University, Xuzhou Clinical School of Nanjing Medical University, Xuzhou, Jiangsu, China.

Background: Vitamin D (VD) deficiency and insulin resistance (IR) increase the risk of non-alcoholic fatty liver disease (NAFLD), but few studies have explored the potential mechanisms by which IR mediates the association between VD and the pathogenesis of NAFLD at the genetic level using publicly available databases.

Methods: This is a cross-sectional study, and we utilized the National Health and Nutrition Examination Survey (NHANES) dataset, as well as data from GSE200765 obtained from the Gene Expression Omnibus (GEO) website. A total of 723 individuals who had completed liver ultrasound examination and the detection of VD levels were included in the final analysis.

Background: The management of acute myeloid leukemia (AML) is hindered by treatment-related toxicities and complications, particularly cytopenia, which remains a leading cause of mortality. Given the pivotal role of the gut microbiota (GM) in hemopoiesis and immune regulation, we investigated its impact on hematologic recovery during AML induction therapy.

Methods: We profiled the GM of 27 newly diagnosed adult AML patients using 16S rRNA amplicon sequencing and correlated it with key clinical parameters before and after induction therapy.

Clinical Significance and Pathogenic Mechanisms of Long Non-Coding RNA TRPM2-AS in Cancers.

Technol Cancer Res Treat

January 2025

School of Basic Medical Sciences, Chengdu Medical College, 783 Xindu Avenue, Chengdu, 610500, Sichuan, China.

Long non-coding RNAs (lncRNAs) are known to play vital roles in human cancers. LncRNA TRPM2-AS has been found to be upregulated in various types of cancers. The elevated levels of TRPM2-AS are associated with important clinicopathological parameters such as tumor size, tumor stage, and lymph node metastasis, revealing that TRPM2-AS could be a potential target for cancer diagnosis, prognosis and treatment.

Plant secondary metabolites (PSMs) may improve gastrointestinal health by exerting immunomodulatory, anti-inflammatory and/or antiparasitic effects. Bark extracts from coniferous tree species have previously been shown to reduce the burden of a range of parasite species in the gastrointestinal tract, with condensed tannins as the potential active compounds. In the present study, the impact of an acetone extract of pine bark () on the resistance, performance and tolerance of genetically diverse mice () was assessed.
