Domest Anim Endocrinol 2021 Mar 23;76:106625. Epub 2021 Mar 23.

Department of Animal Reproduction, School of Veterinary Medicine and Animal Science, University of São Paulo, Pirassununga, São Paulo, Brazil. Electronic address:

The effects of 17β-estradiol (E2) or estradiol benzoate (EB) on PGF2α release were studied in bred-non-pregnant and pregnant Nelore beef heifers. The day of timed artificial insemination (TAI) was designated day 0 (D0), and a single treatment was given on D14. All heifers also received an intravaginal P4 device on D14, and were randomly assigned to three groups: Control (C, P4 device only, n = 12); E2 (1 mg E2 + 9 mg P4, n = 10); or EB (1 mg, n = 10).

Dietary Choline Supplements, but Not Eggs, Raise Fasting TMAO Levels in Participants with Normal Renal Function: A Randomized Clinical Trial.

Am J Med 2021 Apr 16. Epub 2021 Apr 16.

Department of Cardiovascular and Metabolic Sciences, Lerner Research Institute, Cleveland Clinic, Cleveland, OH; Department of Cardiovascular Medicine, Heart and Vascular Institute, Cleveland Clinic, Cleveland OH; Center for Microbiome and Human Health, Cleveland Clinic, Cleveland OH.

Exploring the utility of a novel point-of-care whole blood thrombin generation assay following trauma: A pilot study.

Res Pract Thromb Haemost 2021 Mar 8;5(3):395-402. Epub 2021 Mar 8.

Mayo Clinic Rochester MN USA.

Introduction: Plasma thrombin generation kinetics as measured by the calibrated automated thrombogram (CAT) assay is a predictor of symptomatic venous thromboembolism after trauma. We hypothesized that data from a new prototype assay for measurement of thrombin generation kinetics in fresh whole blood (near patient testing of thrombin generation), will correlate with the standard CAT assay in the same patients, making it a potential tool in the future care of trauma patients.

Methods: Patients were enrolled from June 2018 to February 2020. Read More
