Radioimmunoassay of Sisomicin [PDF]

Antimicrobial Agents and Chemotherapy, 1976
An antibody induced in rabbits against a gentamicin-bovine serum albumin conjugate cross-reacted with the chemically related aminoglycoside, sisomicin, facilitating the development of a sisomicin radioimmunoassay. Sisomicin was labeled with 125 I using an acylating agent [3-(4-hydroxyphenyl)propionic acid-

Rate of erythropoietin formation in humans in response to acute hypobaric hypoxia [PDF]

, 1989
This study was carried out to investigate the early changes in erythropoietin (EPO) formation in humans in response to hypoxia. Six volunteers were exposed to simulated altitudes of 3,000 and 4,000 m in a decompression chamber for 5.5 h. EPO was measured

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 ...

Assessment of postpartum uterine involution and progesterone profile in Nubian goats (Capra hircus)

Journal of Advanced Veterinary and Animal Research, 2014
A total number of 12 postpartum (pp) Nubian goats were included in the study to measure the uterine involution by ultrasonography from day 3 to 31 pp. Coinciding with ultrasonography, blood samples were collected at every 3 days to monitor the ovarian ...

Radioimmunoassay for circulating human guanylin [PDF]

, 1994
A highly specific and sensitive radioimmunoassay for circulating human guanylin (guanylin-22–115) has been developed. Antibodies were raised against the amino-terminus (positions 4–16) of the peptide.

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.

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 ...

Evaluation of a new immunoassay for measuring equine serum insulin and plasma adrenocorticotrophic hormone: A method comparison study

Equine Veterinary Journal, EarlyView.
Abstract Background Insulin dysregulation (ID) and pituitary pars intermedia dysfunction (PPID) are common equine endocrinopathies detected by measurement of circulating insulin and adrenocorticotrophic hormone (ACTH) concentrations. Different assays may yield variable results, limiting comparability.

Effect of Intraduodenal Bile and Na-Taurodeoxycholate on Exocrine Pancreatic Secretion and on Plasma Levels of Secretin, Pancreatic Polypeptide, and Gastrin in Man [PDF]

, 1990
The effect of intraduodenally administered cattle bile (CB) and Na-taurodeoxycholate (TDC) on basal pancreatic secretion and plasma levels of secretin, pancreatic polypeptide (PP), and gastrin were investigated on two separate days in 10 fasting ...
