    Several studies show the correlation between thyroid function and reproductive activity in horses, but no data are available in donkeys. The aim of this study was to determine physiological thyroid changes occurring in 10 pregnant and 14 barren donkeys over a period of 12 months. Blood samples were collected monthly from the jugular vein of pregnant and barren donkeys from June 2008 to June 2009. No significant differences (P 4) and free triiodothyronine (fT3) patterns remained unmodified, regardless of physiological state, with the lowest T4 levels at September and the highest at February, and the lowest fT3 levels at June and the highest at July, in both pregnant and barren donkeys. Ranges of total triiodothyronine (T3) concentrations in pregnant donkeys over a 12 months period ranged from 1.57 to 2.90 nmol/l, T4 from 31.01 to 63.67 nmol/l, fT3 from 3.15 to 15.52 pmol/l and free thyroxine (fT4) from 22.47 to 33.69 pmol/l. Mean T3 concentrations in barren donkeys over a 12 months period ranged from 1.64 to 3.37 nmol/l, T4 from 42.95 nmol/l and 61.90 nmol/l, fT3 from 3.15 to 11.19 pmol/l and fT4 from 25.46 to 35.06 pmol/l. This is the first study that provided a seasonal thyroid hormonal profile in healthy barren and pregnant donkeys

    Shared research resource facilities, also known as core laboratories (Cores), are responsible for generating a significant and growing portion of the research data in academic biomedical research institutions. Cores represent a central repository for institutional knowledge management, with deep expertise in the strengths and limitations of technology and its applications. They inherently support transparency and scientific reproducibility by protecting against cognitive bias in research design and data analysis, and thedy have institutional responsibility for the conduct of research (research ethics, regulatory compliance, and financial accountability) performed in their Cores. The Association of Biomolecular Resource Facilities (ABRF) is a FASEB-member scientific society whose members are scientists and administrators that manage or support Cores. The ABRF Research Groups (RGs), representing expertise for an array of cutting-edge and established technology platforms, perform multicenter research studies to determine and communicate best practices and community-based standards. This review provides a summary of the contributions of the ABRF RGs to promote scientific rigor and reproducibility in Cores from the published literature, ABRF meetings, and ABRF RGs communications
