Salivary and plasmatic oxytocin are not reliable trait markers of the physiology of the oxytocin system in humans

open access: yeseLife, 2020
Single measurements of salivary and plasmatic oxytocin are used as indicators of the physiology of the oxytocin system. However, questions remain about whether they are sufficiently stable to provide valid trait markers of the physiology of the oxytocin ...

Radioimmunoassay for calcitonin.

open access: yesClinical Chemistry, 1982
Calcitonin (CT) is one of the most recently discovered calcium-regulating hormones; the first brief allusion to its existence appeared in 1961.1 The first assays for CT were based on its hypocalcemic property upon injection into rats.2,3 Radioimmunoassays for animal calcitonins soon followed, but the availability of sensitive radioimmunoassays for ...

Glucocorticoid regulation of diurnal spine plasticity in the murine ventromedial prefrontal cortex

open access: yesJournal of Neuroendocrinology, Volume 34, Issue 12, December 2022., 2022
In mice, the core clock gene Per1 is expressed rhythmically within the ventromedial prefrontal cortex (vmPFC). Deep layer pyramidal neurons within the vmPFC exhibit a diurnal rhythm of dendritic spine density. Both Per1 expression and dendritic spine density are increased during the active phase along with the diurnal peak of glucocorticoid (GC ...

Diagnostic efficacy of chemiluminescence immunoassay versus radioimmunoassay in screening primary aldosteronism

open access: yesDi-san junyi daxue xuebao, 2019
Objective To compare the sensitivity and specificity of chemiluminescence immunoassay (CLIA) and radioimmunoassay (RIA) in detection of aldosterone and renin, and to explore the optional detection methods and indicators for screening primary ...

Utilization of Polyspecific Antiserum for Specific Radioimmunoassays: Radioimmunoassays for Rat Fetuin and Bikunin Were Developed by Using Antiserum Against Total Rat Serum Proteins [PDF]

open access: yes, 1993
Polyspecific antiserum against total rat serum proteins was used to develop specific and sensitive radioimmunoassays for fetuin and bikunin, two minor protein components of rat plasma. The radioimmunoassays proved to be highly useful to trace bikunin and

Nomogram model of serum thymidine kinase 1 combined with ultrasonography for prediction of central lymph node metastasis risk in patients with papillary thyroid carcinoma pre-surgery

open access: yesFrontiers in Endocrinology
ObjectiveThe aim of this study was to develop a nomogram, using serum thymidine kinase 1 protein (STK1p) combined with ultrasonography parameters, to early predict central lymph node metastasis (CLNM) in patients with papillary thyroid carcinoma (PTC ...

In Vivo Level of Poly(ADP-ribose)

open access: yesChallenges, 2018
PolyADP-ribosylation is a post-translational modification that plays key roles in cellular physiological functions and DNA damage responses. PolyADP-ribosylation is finely and dynamically regulated by various enzymes and factors involved in the synthesis

The hypothalamic‐pituitary‐adrenal axis response to ovine corticotropin‐releasing‐hormone stimulation tests in healthy and hospitalized foals

open access: yesJournal of Veterinary Internal Medicine, Volume 37, Issue 1, Page 292-301, January/February 2023., 2023
Abstract Background The hypothalamic‐pituitary‐adrenocortical axis (HPAA) response to sepsis can be impaired in critical illness. Corticotropin‐releasing hormone (CRH) stimulation test might assess HPAA function in foals. Objective To evaluate plasma cortisol, ACTH, arginine vasopressin (AVP), and endogenous CRH (eCRH) response to different doses of ...

Reference intervals for plasma, urinary, and salivary concentrations of free metanephrines in dogs: Relevance to the diagnosis of pheochromocytoma

open access: yesJournal of Veterinary Internal Medicine, Volume 37, Issue 1, Page 173-183, January/February 2023., 2023
Abstract Background Measurement of free metanephrines is recommended for screening of pheochromocytoma (PCC) but requires appropriate reference intervals (RIs). Hypothesis/Objectives To report RIs for plasma, urinary and salivary concentrations of free metanephrines and to determine the diagnostic performance of plasma free normetanephrine (pNMN) and ...
