In a previous paper,3) a colorimetric method for the determination of urea nitrogen in blood and urine was presented on the basis of a color reaction of urea with diacetyl monoxime (DAM) in phosphoric acid solution in the presence of D-glucuronolactone (GL), which served to produce a photo-stable color and eliminate the sigmoidal nature of calibration curve observed usually in the DAM method.4)...

acquired color deficiency in the tritan axis in parkinson’s disease has already been reported, manifesting itself as impaired performance in various visual tasks. however, its clinical significance has always been controversial. in this study we evaluated the performance of parkinson s disease patients in lanthony 15-desaturated clinical test and for the first time, compared it with the standar...

A method for the determination of protein in urine by means of the biuret reaction was described by Hiller (1) and by Hiller, McIntosh, and Van Slyke (2), in which pure biuret prepared by Kahlbaum was used as a standard for visual calorimetry. Since Hiller (1) the biuret method has been used for the determination of urinary proteins by Price (3) and by Lehmann (4), and has been widely used in m...

Magnetic lateral flow strip (MLFS) based on magnetic bead (MB) and smart phone camera has been developed for quantitative detection of cocaine (CC) in urine samples. CC and CC-bovine serum albumin (CC-BSA) could competitively react with MB-antibody (MB-Ab) of CC on the surface of test line of MLFS. The color of MB-Ab conjugate on the test line relates to the concentration of target in the compe...

This study investigated the relationship between changes in upon-waking body mass (BM) and changes in urine specific gravity (U(sg)) and urine color (U(col)) from 1 day to the next. Throughout the 5-day investigation, healthy adolescent Singaporean athletes (n = 66) had their upon-waking, bladder-voided BM measured. A small aliquot of the first bladder void each day was collected and analyzed f...

objective(s): in recent years, there has been an increasing amount of study on early diagnosis of kidney injury through sensitive and specific biomarkers. we examined the practical applicability of the urinary levels of nag (n-acetyl-β-d-glucosaminidase), ap (alkaline phosphatase), and ldh (lactate dehydrogenase) as renal dysfunction screening biomarkers in full and pre-term newborns treated wi...

background maintenance of the adequate intraoperative renal perfusion is very important during orthotopic liver transplantation (olt) to prevent acute renal failure. objectives for the first time, this study was designed to survey the effects of octreotide on urine output during anesthesia for olt and early postoperative renal function. patients and methods in this randomized double-blind place...

there are several problems associated with the use of indwelling urethra catheters, including urinary tract infections and mechanical problems. infections have been well researched but mechanical problems associated with blockage, leakage of urine and general discomfort have been less investigated. although education of patients and carers on the use of catheters has been recommended, in practi...

BACKGROUND Workers laboring in steel industries in tropical settings with high ambient temperatures are subjected to thermally stressful environments that can create well-known risks of heat-related illnesses and limit workers' productivity. METHODS A cross-sectional study undertaken in a steel industry in a city nicknamed "Steel City" in Southern India assessed thermal stress by wet bulb glo...
