¿Puede establecerse hoy un valor de fosfatemia como indicador de calidad del tratamiento dialítico?

INTRODUCCIÓN: El trastorno del metabolismo óseo y mineral constituye una grave complicación de la IRC. Respecto al fósforo, las nuevas Guías KDIGO sugieren disminuirla hiperfosfatemia, sin recomendar un valor determinado. Sin embargo, en Argentina se continúa utilizando como indicador de calidad d...

Hipofosfemia en recién nacidos prematuros: un trastorno bimodal

Rev. chil. pediatr; 89 (1), 2018
Las estrategias nutricionales para prematuros extremos con alto aporte de proteínas, han mostrado alteraciones metabólicas con hipofosfemia precoz, especialmente en el grupo de pacientes con restricción de crecimiento intrauterino (Rein). También se presenta hipofosfemia tardía, característica de l...

Nitrogen and phosphorus flux from the production of Nile tilapia through the application of environmental indicators

Braz. j. biol; 78 (1), 2018
Abstract We aimed in this study utilize environmental indicators as a quantitative method to evaluate and discuss the nitrogen (TN) and phosphorus (TP) flux by a production stage grow-out (termination) of Nile tilapia (Oreochromis niloticus) in fishpond. The TN and TP load, the mass balance, the input of...

Combined application of bio-organic phosphate and phosphorus solubilizing bacteria (Bacillus strain MWT 14) improve the performance of bread wheat with low fertilizer input under an arid climate

Braz. j. microbiol; 49 (supl.1), 2018
Abstract This study was aimed to investigate the effect of bio-organic phosphate either alone or in combination with phosphorus solubilizing bacteria strain (Bacillus MWT-14) on the growth and productivity of two wheat cultivars (Galaxy-2013 and Punjab-2011) along with recommended (150-100 NP kg ha−...

Valores de referencia de oxalato, calcio, citrato, ácido úrico, fósforo, magnesio, sulfato y sodio urinarios en alumnos de la carrera de bioquímica de la Universidad Nacional del Litoral, Argentina

INTRODUCCIÓN: La urolitiasis (UL) es una alteración frecuente, cuya incidencia ha aumentado en el último cuarto del siglo XX. Para su diagnóstico se realizan estudios metabólicos para lo cual es necesario contar con valores de referencia (VR) establecidos para la población en cuestión. OBJETIVO: E...

Effects of nutritional conditions on lipid production by cyanobacteria

An. acad. bras. ciênc; 89 (3,supl), 2017
ABSTRACT The present study evaluated the effects of the culturing media and the levels of nitrogen and phosphorus on the growth, biomass productivity and lipid production of four species of Microcystis (M. novacekii, M. aeruginosa, M panniformis and M. protocystis). The lipid extract was obtained by refl...

Thermostable chitinase from Cohnella sp. A01: isolation and product optimization

Braz. j. microbiol; 47 (4), 2016
Abstract Twelve bacterial strains isolated from shrimp farming ponds were screened for their growth activity on chitin as the sole carbon source. The highly chitinolytic bacterial strain was detected by qualitative cup plate assay and tentatively identified to be Cohnella sp. A01 based on 16S rDNA sequen...

Biomethane production from vinasse in upflow anaerobic sludge blanket reactors inoculated with granular sludge

Braz. j. microbiol; 47 (3), 2016
ABSTRACT The main objective of this study was to evaluate the anaerobic conversion of vinasse into biomethane with gradual increase in organic loading rate (OLR) in two upflow anaerobic sludge blanket (UASB) reactors, R1 and R2, with volumes of 40.5 and 21.5 L in the mesophilic temperature range. The UAS...

Biomass allocation and nutrients balance related to the concentration of Nitrogen and Phosphorus in Salvinia auriculata (Salviniaceae)

Braz. j. biol; 76 (2), 2016
Abstract Aquatic plants can use differential allocation (trade-off) of carbon among their structures depending on the nutrition concentration. Given that N and P are limiting in the growth of plants, our questions were: Are the N and P concentrations in S. auriculata related to the biomass allocation to ...

Extratemporal abnormalities in phosphorus magnetic resonance spectroscopy of patients with mesial temporal sclerosis

Arq. neuropsiquiatr; 74 (2), 2016
ABSTRACT Objective We evaluated extratemporal metabolic changes with phosphorus magnetic resonance spectroscopy (31P-MRS) in patients with unilateral mesial temporal sclerosis (MTS). Method 31P-MRS of 33 patients with unilateral MTS was compared with 31 controls. The voxels were selected in the anterior,...
