Comparative Analysis of Liquid Chromatography-Tandem Mass Spectrometry and Radioimmunoassay in Determining Plasma Aldosterone Concentration and Plasma Renin Activity for Primary Aldosteronism Screening [PDF]
Endocrinology and MetabolismLiquid chromatography-tandem mass spectrometry (LC-MS/MS) accurately measures plasma aldosterone concentration (PAC), but its correlation with radioimmunoassay (RIA), equivalent RIA levels, and optimal cutoff for PAC and aldosterone-to-renin ratio (ARR ...

PREDICT‐GTN 1: Can we improve the FIGO scoring system in gestational trophoblastic neoplasia?
International Journal of Cancer, Volume 152, Issue 5, Page 986-997, 1 March 2023., 2023 What's new? The International Federation of Gynaecology and Obstetrics (FIGO) scoring system is used to predict resistance to first‐line single‐agent chemotherapy in gestational trophoblastic neoplasia (GTN) patients. HoweThis system is imperfect, however—one‐third of low‐risk patients develop resistance, and resistance rates increase with FIGO score ...

Journal of Bone and Mineral Research, Volume 38, Issue 1, Page 131-143, January 2023., 2023 ABSTRACT Hyperthyroidism causes secondary osteoporosis through favoring bone resorption over bone formation, leading to bone loss with elevated bone fragility. Osteocytes that reside within lacunae inside the mineralized bone matrix orchestrate the process of bone remodeling and can themselves actively resorb bone upon certain stimuli.

A radioimmunoassay for erythropoietin [PDF]
Blood, 1979 Abstract We describe the development of a radioimmunoassay (RIA) for erythropoietin. Antisera were raised in rabbits with an impure human urinary erythropoietin preparation used as immunogen, but with pure human erytropoietin serving as the labeled antigen in the RIA and as a primary standard.

Frontiers in Endocrinology, 2023 ContextThe 250µg-cosyntropin stimulation test (CST) is used to diagnose non-classic congenital adrenal hyperplasia (NCCAH). The current recommendation is to perform CST when follicular 17-hydroxyprogesterone (17OHP) is 6-30 nmol/L, a cutoff derived from ...

Veterinary Medicine and Science, Volume 9, Issue 1, Page 191-202, January 2023., 2023 In this study, we supplemented the diet of breeding sows either with omega‐6 (control) or omega‐3 (experimental) polyunsaturated fatty acids and examined their effects on the antioxidant system and hormone levels of the animals. In the blood levels of molecules indicating oxidative stress we experienced slight changes, but the feeding of omega‐3 fatty ...

Markers for internal neoplasia in the horse
Veterinary Medicine and Science, Volume 9, Issue 1, Page 132-143, January 2023., 2023 The measurement of tumour markers in horses should be performed only in risk groups or in patients with suspicious clinical/laboratory findings (paraneoplastic syndromes). The results should be interpreted with caution as many factors (e.g., young age, pregnancy and inflammation) affect their concentration or activity.

Veterinary Sciences, 2023 Previously, radioimmunoassay (RIA) has been the only assay to measure insulin-like growth factor-1 (IGF-1) to diagnose hypersomatotropism (HS). Due to radiation concerns, availability, and the cost of IGF-1 RIA, validation of assays for automated ...

Current Advances in Immunoassays for the Detection of β2-Agonists
Foods, 2022 β2-agonists are a group of synthetic phenylethanolamine compounds which are traditionally used for treating bronchospasm. These compounds can also increase skeletal muscle mass and decrease body fat.

Basic &Clinical Pharmacology &Toxicology, Volume 132, Issue 1, Page 21-32, January 2023., 2023 Abstract Uric acid has promoted renal fibrosis and inflammation in experimental studies, but some studies have shown nephroprotective effects due to alleviated oxidative stress. We studied the influence of experimental hyperuricaemia in surgically 5/6 nephrectomized rats. Three weeks after subtotal nephrectomy or sham operation, the rats were allocated
