Determination of Reference Intervals for Selected Liver Biomarkers With Focus on Pre‐ and Postanalytical Factors in Lactating Dairy Cattle

open access: yesVeterinary Clinical Pathology, EarlyView.
ABSTRACT Background Measurement of liver enzymes and metabolites for both clinically healthy and sick cattle is a routine part of dairy herd management. Reference intervals (RIs) are influenced by many variables, including pregnancy, breeding, and geographical variables, and can shift over time.

Reference Intervals of Selected Serum and Plasma Biochemical Analytes in Clinically Healthy Multiparous Holstein Cows During the Periparturient Period

open access: yesVeterinary Clinical Pathology, EarlyView.
ABSTRACT Background Monitoring the metabolic changes during the periparturient period is crucial. Objective We aimed to establish reference intervals (RIs) of several serum and plasma biochemical variables in multiparous periparturient Holstein dairy cows. Methods A total of 238 multiparous dry cows from six commercial dairy farms were enrolled.

Split red blood cell units contain defined extracellular K+ levels, which are improved by a washing procedure

open access: yesVox Sanguinis, EarlyView.
Abstract Background and Objectives We should control free K+ during massive transfusion (>80 mL/kg) of red blood cells (RBCs) in small children. To manage this, several national and international guidelines recommend using RBCs stored only up to 7 days.

Reduced osmoresponsiveness in magnocellular neuroendocrine neurones during chronic salt‐loading

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend We conducted a large systematic survey of the physiological and electrophysiological characteristics of the magnocellular neurosecretory neurones of the supraoptic nucleus in euhydrated and salt‐loaded conditions. Our in vivo electrophysiological recordings show that, after 7 days of salt‐loading, the neuronal responsiveness to ...

Affordable phenomics: Expanding access to enhancing genetic gain in plant breeding

open access: yesThe Plant Phenome Journal, Volume 8, Issue 1, December 2025.
Abstract Plant breeders need to evaluate large breeding populations rapidly and accurately to identify and assess genetic variation responsible for many traits, including yield, quality, resistance, and climate resilience. Although advanced molecular tools, including marker‐assisted selection, genomic selection, and gene editing, are being used to ...
