1. In a series of non-nephritic individuals the total non-protein nitrogen of the blood, determined by Folin's method, was found to lie between 15 and 43 milligrams per 100 cubic centimeters. From 50 to 60 per cent. of this was in the ammonia-urea fraction. 2. In cardiovascular disease with renal congestion, but without other renal lesion, there was no evidence of increase of non-protein nitrog...

The use of three herbal/nutritional products over a period of two months normalized blood urea nitrogen (BUN), serum creatinine, and creatinine clearance in a case of early functional kidney impairment. Although previous use of intravenous EDTA resolved Raynaud's syndrome symptoms, it provided little improvement to abnormal creatinine clearance.

BACKGROUND The aim of the present study was to investigate the impact of the Great East Japan Earthquake on laboratory findings in chronic hemodialysis (HD) patients in Fukushima. METHODS Changes in laboratory findings and cardiothoracic ratio (CTR) between before and after the earthquake were retrospectively analyzed in 90 adult HD patients with end-stage renal disease (ESRD). Two hospitals ...

The apparatus invented by Dr. Luigj Benusi in 1943, in Tirana, was a practical application of the Kowarsky technique and Ambard laws, helping in determining blood urea levels and very important to a variety of diseases, mainly kidney disorders. The apparatus was invented and prepared from very simple laboratory materials, such as glasses, test tubes, corks and volumetric cylinders. Technologica...

This study was conducted to investigate alterations in excretion of urea and total nitrogen after6-8 weeks of daily exercise and to establish if the capacity for amino acid oxidation in muscle is influenced by endurance training. Urea nitrogen excretion was increased in trained compared with untrained rats and nitrogen balance was less positive in trained than in untrained rats. Increased [14C]...

tions a constant (1). If now these conditions are all complied with, but in addition some new factor is introduced, the effect on the rate of urea excretion can be measured by the deviation of the ratio from its constant value. Most of the experiments given in this paper were carried out on the two subjects, Add. and Dru., whose ratios under standard conditions are given in Paper V of this seri...

We developed a new urea sensor for the on-line monitoring of hemodialysis adequacy. The biosensor consisted of an immobilized urease cartridge placed between magnetoinductive conductivity cells. The biosensor output was taken as the conductivity difference between these cells. The device was placed on the ultrafiltrate line of a paired filtration dialysis system. The amount of urease present in...

Nitrogen (N2) fixation is a major source of available N in ecosystems that receive low amounts of atmospheric N deposition. In boreal forest and subarctic tundra, the feather moss Hylocomium splendens is colonized by N2 fixing cyanobacteria that could contribute fundamentally to increase the N pool in these ecosystems. However, N2 fixation in mosses is inhibited by N input. Although this has be...

Under high pressure, triply bonded molecular nitrogen dissociates into singly bonded polymeric nitrogen, a potential high-energy-density material. The discovery of stable high-pressure forms of polymeric nitrogen is of great interest. We report the striking stabilization of cagelike diamondoid nitrogen at high pressures predicted by first-principles structural searches. The diamondoid structure...
