Prolactin Immunoreactivity in Rheumatoid Factor-Containing Specimens: Is it Prolactin, Macroprolactin or Assay Interference?
Specimens containing Rheumatoid factor (RF) were examined for possible interference in Prolactin (PRL) measurement. PRL levels following polyethylene glycol (PEG) treatment were significantly lower than in untreated RFpositive samples (p<0.001; n=43) and spurious hyperprolactinemia was indicated in 7 percent. Gel filtration chromatography suggested that the PRL-like immunoreactivity was from as...

one at the concentration of 7 pg/mg. This result was not challenged by the athlete. Nandrolone has also been identified by this laboratory in the hair of bodybuilders, in concentrations of 1–7 pg/mg (8 ). NA and noretiocholanolone were not detected in any hair. The sensitive, specific, and reproducible method developed appears to be suitable for the detection and quantification of 19-norsteroid...

was performed in 150 mL of a 1 g/L silver nitrate solution for 10 min at room temperature with gentle shaking. The gel was rinsed twice with distilled water to remove excess silver solution and was developed in a solution containing, per liter, 15g of NaOH, 0.1 g of NaBH4, and 0.48 g of formaldehyde. The gel was first washed in 150 mL of this solution (for ;30 s) to precipitate the excess silve...

در این رساله به بررسی رفتار جواب های رده ای از معادلات دیفرانسیل با مشتقات جزیی در دامنه های کراندار می پردازیم . این معادلات به فرم نیم-خطی و غیر خطی برای مسایل مستقیم و معکوس مورد مطالعه قرار می گیرند . به ویژه، تاثیر شرایط مختلف فیزیکی را در مساله، نظیر وجود موانع و منابع، پراکندگی و چسبندگی در معادلات موج و گرما بررسی می کنیم و به دنبال شرایطی می گردیم که متضمن وجود سراسری یا عدم وجود سراسر...
Acs:180 Results Obtained for Macroprolactinemic Samples Multiplexed Mutagenically Separated Pcr: Simulta- Neous Single-tube Detection of the Factor V R506q (g1691a), the Prothrombin G20210a, and the Methyl- Enetetrahydrofolate Reductase A223v (c677t) Variants
(range, 250% to 86%) indicates a highly variable, sampledependent response of the ACS:180 assay to macroprolactin. The great disparity of values observed when comparing results from macroprolactinemic samples measured by the Elecsys or the Immulite assay with the results obtained by a low-reading method such as ACS:180 may reflect variation in the structure of macroprolactin. Macroprolactin is ...
