Rates of Conception by Artificial Insemination of Dairy Cattle

open access: yesJournal of Dairy Science, 1981
Over 41 mo, 1004 first and second service inseminations were evaluated in Holstein cows and heifers of breeding age. Cattle were inseminated either at the end of the heat check in which they were observed in heat (0 h) or at the end of the next heat check (12 h).

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

open access: yesFEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

ABL kinase‐dependent phosphorylation of SH proteins promotes their direct interaction with CRK family SH2 domains

open access: yesFEBS Letters, EarlyView.
CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.

Influence of pH Vaginal Mucosa When Artifical Insemination of Non Return Rate (NRR) and Conception Rate (CR) on Dairy Cow in KSU Tunas Setia Baru Pasuruan East Java [PDF]

open access: yes, 2017
This study aims to find out the vaginal mucosa during artificial insemination against Non Return Rate (NRR) and Conception Rate (CR) in the highlands. Sixty female dairy cows were used as samples in this study. The pH of the vaginal mucosa is measured by

Effects of use of conventional and sexed semen on the conception rate in heifers : A comparison study [PDF]

open access: yes, 2019
Conception rate with the use of sexed semen is lower than that with the use of conventional semen, posing a major problem in the dairy industry. The aim of this study was to understand the risk factors that affect the conception rate after artificial ...
