Safety of mannitol use in bowel preparation: a prospective assessment of intestinal methane (CH4) levels during colonoscopy after mannitol and sodium phosphate (NaP) bowel cleansing

Arq. gastroenterol; 53 (3), 2016
ABSTRACT Background - Adequate bowel preparation is critical for the quality of colonoscopy. Despite reported occurrence of colonic explosion due to methane and hydrogen production by bacterial fermentation during colonoscopy, gas exchange during the procedure is believed to be effective in lowering ex...

Buffering action of acetate on hydrogen production by Ethanoligenens harbinense B49

Electron. j. biotechnol; 19 (5), 2016
The buffering effect of acetate on hydrogen production during glucose fermentation by Ethanoligenens harbinense B49 was investigated compared to phosphate, a widely used fermentative hydrogen production buffer. Specific concentrations of sodium acetate or phosphate were added to batch cultures, and the e...

Requests of laboratory tests for the diagnosis and management of calcium-phosphate disorders in Spain

Rev. méd. Chile; 144 (8), 2016
Background: Knowledge about the variability in the request of calcium-phosphate metabolism laboratory tests in primary care is important to design strategies to improve health system efficiency. Aim: To compare the inter-practice variability in calcium-phosphate metabolism laboratory tests requested by g...

The hardness and chemical changes in demineralized primary dentin treated by fluoride and glass ionomer cement

Background: Fluoride plays an important role in the control of dental caries. Aim: To evaluate the chemical exchange between restoration of glass ionomer cement of high viscosity (GIC) and primary dentin with application of sodium fluoride (NaF) 2% through changes in hardness from uptake of calcium, phos...

Avaliação da obliteração de túbulos dentinários, concentração mineral e permeabilidade dentinária após o uso de dentifrícios contendo trimetafosfato de sódio microparticulado e nanoparticulado: estudo in vitro

O objetivo deste trabalho foi avaliar in vitro a ação do trimetafosfato de sódio microparticulado (TMPm) ou nanoparticulado (TMPn) associado ao fluoreto (F) em formulações de dentifrícios na obliteração dos túbulos dentinários (TD), concentração mineral e condutância hidráulica. Blocos de d...

La diabetes mellitus experimental produce aumento en la expresión de iNOS y altera la vía paracelular de la absorción intestinal de calcio
Experimental diabetes mellitus produces increased iNOS expression and alters the paracellular pathway of intestinal calcium absorption

Actual. osteol; 12 (2), 2016
Previamente hemos demostrado que la diabetes mellitus tipo 1 experimental (D.m.1) inducida por estreptozotocina (STZ) produce estrés oxidativo intestinal en las primeras etapas de la enfermedad, lo que conduce a la inhibición de la absorción intestinal de Ca+2, alterando la vía transcelular del trans...

Efecto de la suplementación con vitamina D en monodosis en niños con parálisis cerebral: Estudio preliminar controlado y aleatorizado

Rev. chil. pediatr; 86 (6), 2015
Introducción: Los niños con parálisis cerebral (PC) tienen mayor riesgo de deficiencia de vitamina D (VD). Aunque existen bastantes estudios sobre VD en PC, hay limitada información sobre suplementación con VD en estos pacientes. Objetivo: Evaluar el efecto de la suplementación con VD en monodosis ...

Necessity to review the Brazilian regulation about fluoride toothpastes

The aim of this study was to evaluate the adequacy of the Brazilian legislation about fluoride toothpaste. A search was conducted in LILACS, Medline and SciELO databases about the fluoride concentration found in Brazilians toothpastes, using descriptors on health. Publications since 1981 have shown that ...

Vitamin D deficiency in risk groups living in tropical curaçao

West Indian med. j; 62 (3), 2013
OBJECTIVE: Curaçao (12 degrees 10N, 69 degrees 0W) is characterized by whole year abundant sunshine (8-10 hours/day). We challenged the automatic assumption that people living in tropical countries do not have a high risk of vitamin D deficiency, and investigated the vitamin D status in a tropical envir...
