Analysis of vitamin B6 vitamers in plasma by cation-exchange high-performance liquid chromatography
The aims of the present study were to evaluate the cation-exchange HPLC assay published by Coburn and Mahuren using 4'-deoxypyridoxine 5'-phosphate as an internal standard, to compare the accuracy of this method of pyridoxal ...
Comparative analysis of in vitro fertilization methods for establishing successful embryo transfer clinics
A review of the laboratory methods and embryo transfer procedures used by seven of the foremost clinics in the world is discussed and evaluated in this article. Based on these facts an in vitro fertilization clinic was ...

Circulating acute phase reactive proteins as indicators of infection in poorly controlled diabetes mellitus
Serum levels of six acute phase proteins (APP) - C-reactive protein (CRP), serum amyloid A (SAA), α1-antitrypsin, haptoglobin and complement fractions C3 and C4 - were serially studied in 24 patients with poorly controlled ...
Plasma vitamin A analysis by liquid chromatography: Probucol interference
The analysis of plasma retinol by high-performance liquid chromatography (HPLC) has recently become a widely accepted routine method. Many of the published reports involve reverse phase separations using methanol or ...
Ventilation-perfusion imaging in evaluating regional lung function in nonpenetrating injury to the chest
The extent of chest wall and lung injury after nonpenetrating injury to the chest (NIC) determine how aggressive and invasive management modalities should be. We investigated the value of ventilation (133Xe) and perfusion ...
Cardiac output during exercise in patients with COPD
Cardiac output response was examined to determine its relationship to exercise and arterial hypoxia, pulmonary hemodynamics, and the clinical/lung mechanics profile of patients with chronic obstructive pulmonary disease ...
Tuberculosis presenting in the neonatal periodd
Tuberculosis presenting during the neonatal period is uncommon, but does occur and may prove fatal if not diagnosed in a timely manner. We describe four such cases and draw attention to urogenital tuberculosis in the mother ...
