OBJECTIVE The purpose of this study was to identify values for net acid base excretion (NABE) which are significant indicators of the acid-base equilibrium in pregnant and young ewes and to show its relationship with other parameters (base, acid, ammonium [NH4], base-acid quotient, sodium [Na], potassium [K], calcium [Ca]) in ovine urine. In contrast to dairy cows, data are rare on these parame...

Methods Urine obtained from healthy volunteers was pooled and sterile filtered. Microdilution tests were performed with Escherichia coli ATCC 25922 in MHB and human urine. The pH of urine was adjusted to values ranging from 5 to 8. For simulating different glucose levels in urine of diabetic patients, urine was adjusted to glucose levels of 100 and 1000 mg/dL. Bacterial growth in different medi...

OBJECTIVE (i) To examine the usefulness of urinary net charge (UNa + UK - UCl) in the evaluation of hyperchloremic metabolic acidosis secondary to diarrhea, distal RTA and proximal RTA and (ii) To characterize the type of distal RTA on the basis of the underlying defect. SETTING Pediatrics division of a tertiary referral center. SUBJECTS Thirty four children with hyperchloremic metabolic ac...

Ammonia oxidation decreases the pH in wastewaters where alkalinity is limited relative to total ammonia. The activity of ammonia oxidizing bacteria (AOB), however, typically decreases with pH and often ceases completely in slightly acidic wastewaters. Nevertheless, nitrification at low pH has been reported in reactors treating human urine, but it has been unclear which organisms are involved. I...

BACKGROUND Primary Sjögren's syndrome is a connective tissue disorder affecting primarily the lacrimal and salivary glands, resulting in xerophtalmia and xerostomia. Extraglandular manifestations are frequent and may include renal involvement. METHODS We studied the prevalence and nature of kidney involvement in 60 Italian patients with primary Sjögren's syndrome, diagnosed according to the E...

PURPOSE To investigate the accuracy of laboratory results of urine samples collected from cotton balls as compared with paired samples collected from catheterization, Preemie Pampers, and Newborn Pampers. METHOD Urine samples were collected from 30 infants by aspirating urine from a cotton ball placed over the meatus. An additional urine sample was obtained from the same infants by aspiration...

Wood, Chris M., C. Louise Milligan, and Patrick J. Walsh. Renal responses of trout to chronic respiratory and metabolic acidoses and metabolic alkalosis. Am. J. Physiol. 277 (Regulatory Integrative Comp. Physiol. 46): R482–R492, 1999.—Exposure to hyperoxia (500–600 torr) or low pH (4.5) for 72 h or NaHCO3 infusion for 48 h were used to create chronic respiratory (RA) or metabolic acidosis (MA) ...

In October, 1931, Helmholtz' published results of the treatment of pyuria in children by means of the ketogenic diet. This form of treatment was suggested to him by the observation that the urine of a patient being treated for epilepsy by ketogenic diet remained free of bacterial cloudiness after being kept for a week. He quotes Neilson2, who in 1920 gave cream to patients with urinary infectio...

BACKGROUND Urine is potentially a rich source of peptide biomarkers, but reproducible, high-throughput peptidomic analysis is often hampered by the inherent variability in factors such as pH and salt concentration. Our goal was to develop a generally applicable, rapid, and robust method for screening large numbers of urine samples, resulting in a broad spectrum of native peptides, as a tool to ...
