What's the difference between iodide and periodide?
Iodide
Definition:
(n.) A binary compound of iodine, or one which may be regarded as binary; as, potassium iodide.
Example Sentences:
(1) Oral potassium iodide therapy resulted in complete cure.
(2) The staining method consisted of sequential treatment of slides with crest serum, fluorosceinated goat-antihuman and swine-antigoat antibodies, and propidium iodide.
(3) Marked resistance to lung damage by toxic thioureas could be induced in older, mature rats by pretreatment with the toxic agent itself (tachyphylaxis), with other toxic and non-toxic antithyroid drugs or with iodine or iodide--even if the rats were pretreated at an early age before susceptibility to the agent developed.
(4) The characteristics of the iodide-induced inhibition of cyclic AMP accumulation in dog thyroid slices have been previously described [Van Sande, J., Cochaux, P. and Dumont, J. E. (1985) Mol.
(5) A nicotine agonist, 11C-labeled (S)-nicotine, was synthesized by N-methylation of (S)-nornicotine with [11C]-methyl iodide in dimethylformamide-dimethylsulfoxide in order to study nicotinic receptors in the human brain by positron emission tomography.
(6) Kinetic analysis of residue and outflow curves of gamma-emitting indicators such as chromium-51-EDTA and iodide-131-thalamate from skeletal muscle gives the possibility to determine the extraction fraction and the plasma flow, and from these two values the capillary diffusion capacity can be calculated (Sejrsen 1970, preliminary report).
(7) Especially a total iodide transport defect can easily be misclassified as thyroid agenesis, since radionuclide imaging cannot visualize the thyroid.
(8) The DNA and protein contents of isolated basal cells were stained with propidium iodide and fluorescein isothiocyanate, respectively, and analysed by flow cytometry using the total protein fluorescence as an estimate of cell size and the DNA fluorescence pulse width as an estimate of nuclear size.
(9) Both of the alpha and beta subunits of intact human follitropin (FSH) were radioiodinated with 125I-sodium iodide and chloramine-T and could be resolved on sodium dodecyl sulfate-polyacrylamide gels.
(10) Accessibility to iodide was much lower, as was the rate of quenching by iodide, adding support to the conclusions from acrylamide quenching.
(11) By contrast, treatment with methyl iodide in dimethylsulphoxide led exclusively to the 3-methyl derivatives in much better yeilds.
(12) The relative standard deviations for bromide at 10(-7) M and for iodide at 10(-8) M concentration were 1.9% and 3.0%, respectively, using a 10-mL sample for the determination without preconcentration.
(13) When [3',5'-125I] T4 was used as a tracer, major labeled products of T4 degradation were inorganic iodide and ethanol-unextracted fraction and no detectable labeled 3,5,3'-triiodothyronine (T3) or 3,3',5'-triiodothyronine (rT3) was generated.
(14) These effects were suppressed by methimazole an inhibitor of iodide oxidation.
(15) A linear correlation was also observed between the iodide concentrations of 24 h collected urine and those of single morning urine (r = 0.91).
(16) Presynaptic motor nerve terminals and their underlying acetylcholine receptors were stained in living animals with the fluorescent dye 4-(4-diethylaminostyryl)-N-methylpyridinium iodide) and tetramethylrhodamine isothiocyanate-conjugated alpha-bungarotoxin (R alpha BTX), respectively, and visualized by video-enhanced fluorescence microscopy.
(17) 1 The actions of 2-n-propyl-4-p-tolylamino-1,2,3-benzotriazinium iodide (TnPBI) and quinidine were compared on guinea-pig heart preparations.
(18) From the results of potassium iodide quenching of fluorescence from the tryptophans, and from attempts to react the native lac repressor with dimethyl(2-hydroxy-5-nitrobenzyl) sulfonium bromide and 2-hydroxy-5-nitrobenzyl bromide, we propose that tryptophan residue 209 is involved in a conformational change of the protein upon binding of inducer, but does not come in direct contact with inducer.
(19) We have developed a methodology that, employing an IgGH + L as a second antibody and side scatter instead of propidium iodide fluorescence, allows a better discrimination of BudR+ cells.
(20) A substantial increase in the dietary iodide intake in many communities has caused a major increase in the total iodide pool in the body and a consequent decrease in the normal thyroid radioiodine uptake.
Periodide
Definition:
(n.) An iodide containing a higher proportion of iodine than any other iodide of the same substance or series.
Example Sentences:
(1) The method makes use of the enzyme acid phosphatase to liberate choline from phosphorylcholine and incorporates the ability of choline to react with potassium triiodide to yield choline periodide for the measurement of choline and phosphorylcholine in liver.
(2) A chemiluminescent assay coupled to a periodide extraction method is described for the measurement of acetylcholine release from the vascular perfused rat phrenic nerve-hemidiaphragm preparation.
(3) The precipitate of betaine periodide is dissolved in ethylene dichloride and measured spectrophotometrically.
(4) Betaine is reacted with potassium triiodide to form betaine periodide, which is selectively precipitated via pH adjustment.
(5) After external radiolabelling by periodide-borotritide and neuraminidase-galactose oxidase-borotritide treatment, only some quantitative changes can be observed.
