Serum Cr and BUN concentrations have been determined by enzymatic colorimetric techniques. The reference intervals for blood hemoglobin (8.six to 16.0 g/dL), serum sodium (146 to 160 mmol/L), serum Cr (0.6 to 2.0 mg/dL), and serum BUN (18.0 to 36.0 mg/dL) in adult cats have been previously established. Serum SDMA concentrations had been determined applying liquidPLOS A single | DOI:10.1371/journal.pone.0153654 April 14,five /Impact of Eating plan on SDMA and Cr in Geriatric Catschromatography-mass spectrometry as previously described [3]. The reference interval for serum SDMA was determined by a industrial laboratory (IDEXX Laboratories, Westbrook, ME) in healthier cats using the upper two.4-Bromo-1,2,3,5,6,7-hexahydro-s-indacene Purity 5 quartile getting the upper limit from the reference range, i.Buy1-Bromo-3,4-difluoro-2-methoxybenzene e., 14 g/dL. All serum SDMA concentrations had been determined retrospectively following the feeding trial ended from serum stored in serum banks. Urine certain gravity was determined using a refractometer. Urine Cr concentration was used as an internal reference and measured using the identical assay as serum Cr. Urine protein concentrations have been determined applying urine supernatant (benzethonium chloride turbidometric system).PMID:24179643 Urine protein to Cr (UPC) ratio calculations are reported as mg/dL protein: mg/dL Cr.Statistical analysesStatistical analyses had been performed utilizing Statistical Analysis Software program version 9.two (SAS Institute, Cary, NC). Response variables had been tested for normality by the Shapiro-Wilk test. To establish the effect of meals, data from cats were analyzed as repeated-measures-in-time, randomized design and style working with common linear models in PROC MIXED and also the Satterthwaite approximation to identify the denominator degrees of freedom for the tests of fixed effects. Animal was deemed the experiment unit. The variance-covariance structure of repeated measures of your same animal across time was modeled making use of an unstructured variance-covariance matrix, which was essentially the most parsimonious model based on the Aikaike Details Criterion. Fixed effects in the model have been treatment group (owner’s-choice foods, test food), time (0, 3, and six months), and t.
