Impact of the transition from radioimmunoassay (RIA) to chemiluminescent enzyme immunoassay (CLEIA) for the measurement of plasma aldosterone concentration (PAC) on the diagnosis of primary aldosteronism (PA) via retrospective analyses in Okinawa, Japan

Endocrine Journal
In Japan, the traditional method for measuring plasma aldosterone concentration (PAC) was radioimmunoassay (RIA), which had several challenges, including poor traceability of certified reference materials and reduced detection sensitivity at low ...

Terminal deoxynucleotidyltransferase. Serological studies and radioimmunoassay [PDF]

, 1976
Mouse antisera against calf terminal deoxynucleotidyltransferase (terminal transferase) have been prepared. The sera have been used to characterize terminal transferase both by studying inhibition of enzyme activity and by developing a competition ...

Serum parathyroid hormone levels and renal handling of phosphorus in patients with chronic renal disease [PDF]

, 1972
In eight patients with advanced renal insufficiency (inulin clearance 1.4-9.1 ml/min), concentrations of serum calcium (S[Ca]) and phosphorus (S[P]) were maintained normal (S[Ca] > 9.0 mg/100 ml, (S[P] < 3.5 mg/100 ml) for at least 20 consecutive days ...

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 ...

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.

Comparison of Enzyme‐Linked Immunosorbent Assay and Lateral Flow Assay to Measure Thyroid‐Stimulating Hormone and Free T4 in Human Serum

Journal of Clinical Laboratory Analysis, EarlyView.
TSH and fT4 measured by EIA and EFL were evaluated by two regression models: Deming and Passing Bablok. The Deming regression for TSH shows that the mean levels obtained by both methods do not present significant differences; however, the Passin‐Bablok regression identifies significant bias between both methods in the range of concentrations studied ...

Hypocretin Levels in Sporadic and Familial Cases of Canine Narcolepsy

Neurobiology of Disease, 2001
Familial and sporadic forms of narcolepsy exist in both humans and canines. Mutations in the hypocretin receptor 2 gene (Hcrtr 2) cause canine familial narcolepsy.

Perfil hormonal de Progesterona durante o ciclo Estral em novilhas Nelore confinadas com Diferentes Ondas de Crescimento Folicular Plasma Progesterone Level during the Estrous Cycle in Nelore Heifers Confined with Two, Three and Four Waves of Follicular Growth

Revista Brasileira de Zootecnia, 2001
Efetuaram-se coletas diárias de sangue, de 16 novilhas Nelore confinadas, para análise de progesterona plasmática pelo método de radioimunoensaio (RIA). Os dias analisados para progesterona foram o dia zero (estro) e a cada três dias até o dia -1 e o dia

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).
