NON-RADIOMETRIC IMMUNOASSAYS [FLUOROIMMUNOASSAY (FIA) AND FLUOROMETRIC ENZYME IMMUNOASSAY (FEIA)] WITH RADIOIMMUNOASSAY (RIA) FOR EVALUATION OF ADRENAL FUNCTION IN NORMAL AND HYPERCORTISOLEMIC DOGS [PDF]

Ciência Rural, 2002
Non-radiometric immunoassays offer many advantages over radiometric assays, such as higher stability of kit compounds and absence of potential hazardous effects for users and environment. The comparison of cortisol measurements by fluoroimmunoassay (FIA)

Exploring Cerumen as an Alternative Matrix for Drug Detection and Quantification: Method Development and Application in Clinical Samples

Drug Testing and Analysis, EarlyView.
An LC–MS/MS method was developed for the detection of 33 psychoactive medications in cerumen (earwax) and applied to the samples of 60 psychiatric inpatient volunteers. The findings highlighted the utility of cerumen as an innovative biospecimen in clinical toxicological analysis.

Commonalities of platelet dysfunction in heart failure with preserved ejection fraction and underlying comorbidities

ESC Heart Failure, Volume 12, Issue 2, Page 1013-1028, April 2025.
Abstract Heart failure with preserved ejection fraction (HFpEF) is characterized by a lack of a specific targeted treatment and a complex, partially unexplored pathophysiology. Common comorbidities associated with HFpEF are hypertension, atrial fibrillation, obesity and diabetes.

Hair Testosterone and Cortisol Concentrations in Pre- and Post-Rut Roe Deer Bucks: Correlations with Blood Levels and Testicular Morphometric Parameters

Animals, 2018
The roe deer is a seasonally breeding species with a reproductive cycle regulated by endogenous rhythms and photoperiod-sensitivity. Sexually mature bucks show hormonal and testicular activation during the reproductive season, with a peak in the rut ...

Prevalence of insulin dysregulation in a sport horse population as determined by traditional and stall‐side testing

Equine Veterinary Journal, EarlyView.
Abstract Background The prevalence of insulin dysregulation (ID) has not been investigated in sport horses. Stall‐side insulin assays offer convenience but need further validation. Objectives To determine the prevalence of and risk factors for ID in a sport horse population using an oral sugar test (OST) and assess agreement between stall‐side and ...

Radioimmunoassay for calcitonin.

Clinical 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 ...

Corticosterone and Mitochondrial Efficiency Are Associated With Changes in DNA Oxidative Damage During an Acute Stress Response in Leach's Storm‐Petrels (Hydrobates leucorhous)

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT The ability of organisms to effectively respond to challenges is critical for survival. We investigated how an acute stressor affected corticosterone, mitochondrial function, and DNA oxidative damage in a wild population of Leach's storm‐petrels (Hydrobates leucorhous).

Assessing cortisol concentration in different matrices: predictive potential and relationship with production levels, lactation stage and parity in dairy buffaloes

Italian Journal of Animal Science
Cortisol is the primary biomarker associated with the hypothalamic–pituitary–adrenal (HPA) axis. This research aimed at assessing the predictive potential and the relationship of cortisol concentrations in four media (blood, milk, whey and hair) with ...

Clinical Characteristics and Treatment Management of Seronegative Myasthenia Gravis: A Systematic Review of the Literature

Muscle &Nerve, EarlyView.
ABSTRACT Seronegative myasthenia gravis (SNMG) is characterized by the absence of detectable autoantibodies against known MG targets, despite clinical and electrophysiological evidence of a postsynaptic neuromuscular junction disorder. The aim of this systematic review was to better define clinical features, diagnostic clues and treatment outcome of ...
