In 1988 and 1990 screening for HbAlc and albumin excretion rate (AER) in diabetic children was carried out throughout Denmark. Each study included about 1,000 diabetic patients and found HbAlc and insulin requirements increased during maturation in both sexes. No significant differences in HbAlc were seen among adolescents treated with two, three or more daily insulin injections. The prevalence...

During the pubertal years the overnight urinary excretion rate of growth hormone (hGHu) increases to three to four times the prepubertal rate, reaching a peak in girls at 13 years and in boys at 15 years. After puberty the mean rate of overnight hGHu is twice that before puberty.

A drop has been observed in the renal threshold for hemoglobin in dogs, of over 60 per cent, following repeated injections daily. It was not associated with a cessation of tubular reabsorption. Hemoglobin excretion rate curves, obtained initially and after lowering the threshold, have proved to be parallel lines originating at the respective levels. Hemoglobin containing radio-active iron has b...

A completely randomized experimental design was conducted to estimate ammonia excretion rate by red tilapia (Oreochromis sp.) during different stages of its growth in recirculating water system units typically designed to meet the experiment purposes. Eight weight groups each containing 75individuals of 20, 30, 40, 60, 80, 120, 180 and 200g average weight were considered as treatments in duplic...

We studied the effect of protein and protein-free energy intake on the degradation rate of myofibrillar protein in preruminant calves in two experiments. Both experiments were similar in design but were performed with two live weight ranges: 80 to 160 kg (Exp. 1) and 160 to 240 kg (Exp. 2). In each experiment, calves were allocated to either an initial slaughter group or to one of 12 treatments...

BACKGROUND Assessment of human exposure to non-persistent pesticides such as pyrethroids is often based on urinary biomarker measurements. Urinary metabolite levels of these pesticides are usually reported in volume-weighted concentrations or creatinine-adjusted concentrations measured in spot urine samples. It is known that these units are subject to intra- and inter-individual variations. Thi...

a study was designed to evaluate the normal value of 24 hr urinary calcium levels in the city of yazd. the average urinary excretion of calcium in a sample of 329 persons randomly selected was 232 mg/day, while patients with a history of recurrent urolithiasis excreted 20x mg/day. there is evidence which shows that more important factors than the amount of urinary calcium exist which influence ...

In many contexts, nutrient excretion by consumers can impact ecosystems by altering the availability of limiting nutrients. Variation in nutrient excretion can be predicted by mass balance models, most of which are premised on two key ideas: (1) consumers maintain fixed whole-body nutrient content (i.e., %N and %P), so-called fixed homeostasis; (2) if dietary nutrients are not matched to whole-...

First, multiple reports focus on the pharmacokinetics, excretion, metabolism, and distribution characteristics of drugs to contribute clinical translation or rational drug use. Li et al reported a body-protective compound 157 (BPC157) in rats dogs. The results revealed that main excretion pathways BPC157 involved urine bile. These target compound. A study by Shen
