Parathyroid carcinoma is very rare, with only a few documented cases. Hence, metastatic lesions are infrequently documented on scintigraphic imaging. We present a case of a 63-year-old female presenting with elevated serum levels of ionized calcium and parathyroid hormone (PTH) who was referred to our department for a parathyroid scan with SPECT/ CT. Parathyroid scintigraphy showed a focus of i...
Stunting is a linear growth failure as an indicator of malnutrition status which identified by comparing the height children with normal according to same age and sex. Children are categorized stunting if child`s shorter than average sex has standard deviation below minus 2 who. The cause multifactorial, including disruption hormone function, one parathyroid hormone. Parathyroid Hormone-related...
In mammals, phosphocalcic and bone metabolisms are mainly regulated by parathyroid hormone, parathyroid hormone-related peptide (PTHrP) and 1α,25-dihydroxyvitamin D or calcitriol. In camels, circulating levels of calcitriol are 10 times higher than those determined in other ruminants and further increase during early lactation. Calcitriol and parathyroid-related peptide stimulate intestinal abs...
We used RNA interference, which causes sequence-specific degradation of target mRNAs to suppress the production of parathyroid hormone by cells of patients with secondary hyperparathyroidism in vitro and in vivo. Transfection of small interfering RNA (siRNA) against human parathyroid hormone into monolayers of parathyroid cells cultured from these patients caused a dose-dependent decrease of se...
The response of normal bovine parathyroid glands to hypercalcemia was assessed in vivo by radioimmunoassay of immunoreactive parathyroid hormone concentrations in parathyroid effluent blood obtained by surgical cannulation of both anesthetized and nonanesthetized calves. Hypercalcemia was induced for periods of 0.3-35 h by intravenous infusion of a solution of calcium chloride. Assessment of im...
A synthetic analog of bovine parathyroid hormone (bPTH), [tyrosine-34] bPTH-(7-34)NH2, was found to inhibit parathyroid hormone action in vivo. When the analog and parathyroid hormone were infused simultaneously to rats at a molar ratio of 200 to 1, the analog inhibited the excretion of urinary phosphate and adenosine 3',5'-monophosphate. When infused alone at the same dose rate, the analog was...
Bovine parathyroid hormone has been isolated in homogeneous form, and its complete amino acid sequence determined. The bovine hormone is a single chain, 84 amino acids long. It contains amino-terminal alanine, and carboxyl-terminal glutamine. The bovine parathyroid hormone is approximately three times the length of the newly discovered hormone, thyrocalcitonin, whose action is reciprocal to par...
conclusions radiofrequency ablation may be used successfully in the treatment of parathyroid adenoma when a patient cannot tolerate surgery. case presentation a 47-year-old patient was referred to our hospital (namazi hospital, shiraz, iran) in april, 2015 with intracranial hemorrhage, as well as high serum calcium and pth (parathyroid hormone) levels (12.1 mg/dl and 1062 pg/ml, respectively), ...
