Eletrólitos séricos e prognóstico em doentes submetidos a gastrostomia endoscópica

Arq. gastroenterol; 55 (1), 2018
ABSTRACT BACKGROUND: Percutaneous endoscopic gastrostomy (PEG) is a gold standard for long term enteral feeding. Neurologic dysphagia and head/neck cancer are the most common indications for PEG as they can lead to protein-energy malnutrition and serum electrolyte abnormalities, with potential negative...

Influence of nutritional status, laboratory parameters and dietary patterns upon urinary acid excretion in calcium stone formers

J. bras. nefrol; 40 (1), 2018
ABSTRACT Introduction: Obesity and Metabolic Syndrome (MS) are associated with low urinary pH and represent risk factors for nephrolithiasis, especially composed by uric acid. Acidogenic diets may also contribute to a reduction of urinary pH. Propensity for calcium oxalate precipitation has been shown t...

Índice calcio-creatinina en una muestra matutina de orina para la estimación de hipercalciuria asociada con hematuria no glomerular observada en las edades infanto-juveniles

Resumen Introducción: La hipercalciuria suele revelarse durante el diagnóstico diferencial de la hematuria que acompaña a la litiasis renal. La exactitud diagnóstica de la excreción urinaria de calcio puede afectarse por las insuficiencias asociadas con la colección de orina de 24 horas. En este ...

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...

Efeito do trimetafosfato de sódio, associado ou não ao fluoreto, na biomassa e fluido do biofilme misto contendo Streptococcus mutans e Candida albicans

O presente estudo teve por objetivo verificar o efeito do trimetafosfato de sódio (TMP), associado ou não ao fluoreto (F), sobre células cultiváveis, biomassa total, atividade metabólica e composição da matriz extracelular de biofilmes mistos de S. mutans e C. albicans, bem como sobre as concentra...

The aminoglycoside antibiotic gentamicin is able to alter metabolic activity and morphology of MDCK-C11 cells: a cell model of intercalated cells

Braz. j. med. biol. res; 51 (10), 2018
It is well known that the aminoglycoside antibiotic gentamicin is capable of causing damage to kidney cells. Given the known involvement of Ca2+ in the nephrotoxic action of gentamicin, the purpose of this study was to establish a relationship between the concentration of intracellular Ca2+ ([Ca2+]i) and...

Comparative study of oral and salivary parameters in patients with and without loss of bone mass

Abstract Osteoporosis is an insidious and increasingly prevalent disease that can cause fractures and affect patients' quality of life. The current study comparatively evaluates patients with and without loss of bone mass in terms of salivary calcium, viscosity, and pH. A controlled cross-sectional study...

Extracellular calcium increases fibroblast growth factor 2 gene expression via extracellular signal-regulated kinase 1/2 and protein kinase A signaling in mouse dental papilla cells

J. appl. oral sci; 26 (), 2018
Abstract We previously reported that elevated extracellular calcium (Ca2+) levels increase bone morphogenetic protein 2 expression in human dental pulp (hDP) cells. However, it is unknown whether extracellular Ca2+ affects the expression of other growth factors such as fibroblast growth factor 2 (FGF2). ...

Physicochemical properties of calcium silicate-based formulations MTA Repair HP and MTA Vitalcem

J. appl. oral sci; 26 (), 2018
Abstract Objective This study aimed to analyze the following physicochemical properties: radiopacity, final setting time, calcium release, pH change, solubility, water sorption, porosity, surface morphology, and apatite-forming ability of two calcium silicate-based materials. Material and methods We te...

Demetallization of Enterococcus faecalis biofilm: a preliminary study
