Correlation among 25-hydroxy-vitamin D assays.
CONTEXT Measurement of circulating 25-hydroxy-vitamin D [25(OH)D]) is the accepted clinical indicator of vitamin D status. However, between-laboratory differences in measurement of this analyte exist, which may confound clinical care. OBJECTIVES We investigated the current agreement of 25(OH)D measurement in clinical laboratories and explored the possibility that simple calibration would impr...
متن کامل25-Hydroxy- and 1α,25-Dihydroxycholecalciferol Have Greater Potencies than 25-Hydroxy- and 1α,25-Dihydroxyergocalciferol in Modulating Cultured Human and Mouse Osteoblast Activities
Despite differences in the phamacokinetics of 25-hydroxycholecalciferol (25(OH)D3) and 25-hydroxyergocalciferol (25(OH)D2) in man, the effects of these and their 1α-hydroxylated forms (1,25(OH)2D3 and 1,25(OH)2D2) on cellular activity of vitamin D-responsive cells have hardly been compared. We studied differences in the effects of these metabolites on cell number, gene transcription, protein ex...
متن کاملN-(4-Fluorobenzoyl)-2-hydroxy-4-methylbenzohydrazide
In the title compound, C(15)H(13)FN(2)O(3), the aromatic rings are aligned at an angle of 10.15 (3)°. The mol-ecules are packed with π-π stacking inter-actions [mean inter-planar distances of 3.339 (2) and 3.357 (3) Å] and the crystal structure is stabilized by inter-molecular N-H⋯O and O-H⋯O hydrogen bonds. An intramolecular N-H⋯O interaction also occurs.
متن کامل4-Hydroxy-2,2,6,6-tetramethylpiperidinium trifluoroacetate
The title compound, C(9)H(20)NO(+)·C(2)F(3)O(2) (-), is an important inter-mediate in the synthesis of hindered light stabilizers. The piperidinium ring adopts a chair conformation with the hydroxyl group in an equatorial position. The crystal packing is stabilized by O-H⋯O and N-H⋯O hydrogen bonds. The CF(3) group is disordered over two positions with almost equal site occupancy factors.
متن کاملNefro - 25-4 - MIOLO.indd
We present the case of a fourteen-year-old girl who complained of depression, weight gain and hirsutism. She was obese, apathetic and had poverty of movements. She had anaemia, deteriorated renal function and elevated hepatic enzymes. Free T3 was <0.19 pg/mL and TSH 276 UI/mL. Antithyroglobulin and antimicrosome antibodies were positive, and the thyroid ultrasonography revealed thyroiditis. She...
