OBJECTIVE: To investigate the reliability and validity of refractometry, hydrometry, and reagent strips in assessing urine specific gravity in collegiate wrestlers. DESIGN AND SETTING: We assessed the reliability of refractometry, hydrometry, and reagent strips between 2 trials and among 4 testers. The validity of hydrometry and reagent strips was assessed by comparison with refractometry, the ...

The performance of a prototype instrument, “CLINILAB Automated Urine Analyzer,” for automation and mechanization of urinalysis, was studied. Results of the chemical tests for which the instrument is used-pH, glucose, protein, ketone, bilirubin, and occult blood-were compared to those obtained on the same urine specimens by using “‘Bili-Labstix’ Reagent Strips.” Results for specific gravity obta...

objective due to the high prevalence of syndrome of inappropriate antidiuretic hormone secretion (siadh). this study was carried out to evaluate the prevalence and relevant parameters of siadh in children with septic and aseptic memingitis hospitalized at kashan shahid beheshti hospital between 1996 and 2006. materials & methods this descriptive study was conducted on 230 patients with meningit...

BACKGROUND Microalbuminuria is known to be a harbinger of serious complications in type 2 diabetes mellitus. Since medical intervention at the onset of microalbuminuria can be critical in reducing these adverse outcomes, it is widely agreed that type 2 diabetic patients should be screened for microalbuminuria. The purpose of the present study is to evaluate Micral test strips in conjunction wit...

The effects of density and food on remating were investigated using Drosophila melanogaster. The frequency of remating was unaffected by density for some combinations of fly strains but was reduced at low relative densities for other combinations. Until females had used most of their stored sperm, remating was less likely when food was absent or contact with food was prevented. Food availabilit...

In fact, we suspect that much more is true: we conjecture that this relative density does not change after restriction to any set of primes defined by a Cebatorevstyle Frobenius condition; that is, we expect that the sets (0.1) yield sets of primes of positive density which are quite different from those sets determined by Galois theoretic conditions. See Conjecture 1.2 for a precise statement....
