Evaluation of a commercial automated assay for rapid serum progesterone determination in cattle, sheep and goats

Veterinary Record, EarlyView.
Abstract Background In ruminants, information on serum progesterone concentrations can be important in monitoring the oestrous cycle for pregnancy testing and the detection of endocrine disorders. We aimed to evaluate the suitability of a commercial enzyme‐linked fluorescence assay (ELFA), the MINI VIDAS (bioMérieux, Nürtingen), for measuring ...

Fractionation of human serum lipoproteins by single-spin gradient ultracentrifugation: quantification of apolipoproteins B and A-I and lipid components

Journal of Lipid Research, 1977
A sensitive and reproducible method has been developed for separation of the major serum lipoproteins from 1 ml or less of human serum by isopycnic density gradient ultracentrifugation.

Plasma testosterone and 11-ketotestosterone levels of male pacu Piaractus mesopotamicus (Cypriniformes, Characidae)

Brazilian Journal of Medical and Biological Research, 1997
The levels of testosterone (T) and 11-ketotestosterone (11-KT) of the South American pacu Piaractus mesopotamicus were determined by radioimmunoassay during two stages of the reproductive cycle, i.e., resting and maturation, and the gonadosomatic index ...

Quantification of steroid hormones in free‐ranging Apennine wolf Canis lupus italicus hair samples collected post‐mortem

Wildlife Biology, EarlyView.
After decades of dramatic reductions in their populations, Italian wolves have begun recolonizing parts of their historic range. This growth in populations can lead to potential conflicts with human activities, which remain the main cause of wolf mortality.

Development and validation of a solid phase radioimmunoassay system for the determination of pregnancy-associated glycoproteins in bovine serum [PDF]

Kafkas Universitesi Veteriner Fakültesi Dergisi
The Pregnancy-Associated Glycoproteins (PAGs) belong to aspartic protease family and are synthesized by trophoblast cells of ruminant placenta and secreted into maternal blood and milk.

First Non‐Invasive Monitoring of Fecal Steroids in Greater Caribbean Manatees (Trichechus manatus manatus)

Zoo Biology, EarlyView.
This study established the first fecal hormonal reference values (P4/E2) for the Greater Caribbean manatee. Using non‐invasive ELISA, the authors found no significant differences between mature and immature females, highlighting that long‐term monitoring and ultrasounds are essential to fully understand their complex reproductive cycles.

Rapid hormonal rise in honey bees due to heat‐shock is mitigated by a primer pheromone

Insect Science, EarlyView.
We show that honey bee foragers increased juvenile hormone (JH) titers significantly after heat‐shocked for 1 h at 40 °C, but this increase is dependent on social conditions. Increase of JH titers only happened when bees were isolated (one worker bee per vial) but not in groups.

Adrenal venous sampling criteria for chemiluminescent enzyme immunoassay as a preferable alternative to radioimmunoassay in primary aldosteronism

Endocrine Journal
Plasma aldosterone concentration (PAC) was routinely measured using radioimmunoassay (RIA); however, the RIA kit was discontinued in March 2021 in Japan.

Dendrimeric Antigens for Passive Mast Cell Activation in the Evaluation of Amoxicillin Allergy

Allergy, EarlyView.
DeAns with defined nanoscale structure reveal that conjugate size and determinant density govern IgE‐mediated effector‐cell activation in AX allergy. All DeAn generations bind to sIgE in inhibition immunoassay, but only larger DeAns trigger FcεRI‐dependent responses in mouse MC, huRBL‐2H3, and LUVA cells.
