Historical perspectives In this issue of the JCI, the elegant publication by Hoff and colleagues (1), by serendipity or on purpose, falls on the 40th anniversary of the discovery of calcitonin (CT) as a hypocalcemic principle from the parathyroid gland (2). The parathyroid origin of calcitonin was revisited shortly thereafter, and a thyroid C cell origin was firmly established (3, 4). Calcitoni...
abstract the third millennium has started, but the world is facing with serious challenges in achieving international security and peace. various human rights violations have lead the states to find means to protect human rights. also article 55 of the united nations charter introduces the respect to human rights and fundamental freedom as the most suitable ways to realize peace and security. ...
Background and purpose: Osteoporosis is a general skeletal disease characterized by decreased bone mass over the years, bone fractures, decreased bone strength, and consequently increased bone fragility and fracture susceptibility. There is paucity of information about the effect of calcitonin on osteoporosis in Iran. The current study aimed at investigating the relationship between serum calci...
introduction : osteon® is an alloplastic material containing 70% hydroxyapatite and 30% β-tcp. calcitonin, a hormone produced by the thyroid gland, not only prevents bone resorption by reducing both the number and the activity of osteoclasts, but also stimulates bone formation. considering the favorable effects of calcitonin on bone formation, we hypothesized that the addition of calcitonin to ...
Several factors which affect the sensitivity of calcitonin bioassay were investigated. As to the assay animals, Sprague-Dawley and Holtzman rats were more sensitive than Wistar rats. In mice, C3H III strain gave better response to calcitonin than CF 1 and ddN strains. In each strain, younger rats were more sensitive than older ones. It was also demonstrated that the longer was the period of low...
Immunohistological methods were used to investigate the presence of carcinoembryonic antigen, beta 1 pregnancy specific glycoprotein, beta subunit of human chorionic gonadotrophin, human placental lactogen, calcitonin, and keratin in formalin fixed tissue from 29 malignant mesotheliomas and 27 pulmonary adenocarcinomas. Malignant mesotheliomas were negative for tumour markers except for the bet...
Therapeutic agents that block the calcitonin gene-related peptide (CGRP) signaling pathway are a highly anticipated and promising new drug class for migraine therapy, especially after reports that small-molecule CGRP-receptor antagonists are efficacious for both acute migraine treatment and migraine prevention. Using XenoMouse technology, we successfully generated AMG 334, a fully human monoclo...
Immunohistological methods were used to investigate the presence of calcitonin, thyrotrophin, carcinoembryonic antigen, beta pregnancy specific glycoprotein, human placental lactogen, and the beta subunit of human chorionic gonadotrophin in formalin fixed lung tumour tissue sections. Carcinoembryonic antigen was observed in 71% of 101 tumours studied (70%), beta 1 pregnancy specific glycoprotei...
