Eje somatotrópico y marcadores moleculares del metabolismo mineral en niños en diálisis

Rev. chil. pediatr; 88 (1), 2017
El retraso del crecimiento de los niños con enfermedad renal crónica es de origen multifactorial, incluyendo la resistencia a hormona de crecimiento (GH) y alteraciones en el metabolismo mineral óseo. Objetivos: 1) Caracterizar marcadores del metabolismo mineral: FGF23-Klotho y del eje somatotrópico:...

Ghrelin plasma levels, gastric ghrelin cell density and bone mineral density in women with rheumatoid arthritis

Braz. j. med. biol. res; 50 (6), 2017
Generalized bone loss can be considered an extra-articular manifestation of rheumatoid arthritis (RA) that may lead to the occurrence of fractures, resulting in decreased quality of life and increased healthcare costs. The peptide ghrelin has demonstrated to positively affect osteoblasts in vitro and has...

Relationship between glycemic control and OPG gene polymorphisms with lower bone mineral density in patients with type 1 Diabetes mellitus

ABSTRACT The aim of the present study was to investigate the bone mineral density (BMD) of patients with type 1 Diabetes mellitus (T1DM). We also assessed the association between osteoprotegerin (OPG) genetic polymorphisms and BMD. Genotyping was performed for 1181G>C and 163A>G OPG polymorphisms b...

Ganho de densidade mineral óssea relacionado à prática de basquetebol em meninos: estudo de coorte

INTRODUCTION: In recent decades, the prevalence of osteoporosis has significantly increased, impacting in a significant manner on health care costs worldwide. OBJECTIVE: To analyze the impact of basketball practice on bone mineral density of male adolescents. METHODS: 9 - month cohort study carried out w...

Tridax procumbens flavonoids: a prospective bioactive compound increased osteoblast differentiation and trabecular bone formation

Biol. Res; 50 (), 2017
BACKGROUND: The Tridax procumbens extracts (TPE) are known for their ethno-medicinal properties to increase osteogenic functioning in mesenchymal stem cells. Recently, we found that the T. procumbens flavonoids (TPF) significantly suppressed the RANKL-induced osteoclasts differentiation and bone resorpti...

Ensayo estructural no destructivo utilizando microtomografía de rayos X para estimación de diferencias de densidad másica en muestras óseas de conejo

Int. j. morphol; 34 (4), 2016
Al realizarse estudios sobre muestras óseas para analizar características como dureza, densidad y salud, se suelen utilizar equipamientos que permiten la cuantificación de la densidad electrónica, proporcional a la densidad másica, que se relaciona directamente con la densidad mineral ósea. El test...

Correlation between ultrasound velocity and densitometry in fresh and demineralized cortical bone

Clinics; 71 (11), 2016
OBJECTIVE: To compare ultrasound propagation velocity with densitometry in the diaphyseal compact cortical bone of whole sheep metatarsals. METHODS: The transverse ultrasound velocity and bone mineral density of 5-cm-long diaphyseal bone segments were first measured. The bone segments were then divided ...

Low-level laser therapy associated to a resistance training protocol on bone tissue in diabetic rats

ABSTRACT Objective The present study aimed to evaluate the in vivo response of a resistance training and low-level laser therapy (LLLT) on tibias and femurs of rats with diabetes mellitus (DM). Materials and methods Forty male Wistar rats were randomly distributed into four experimental groups: contr...

Excesivo rastreo de osteoporosis en mujeres menores de 65 años: estudio de corte transversal

Salud colect; 12 (3), 2016
RESUMEN El rastreo de osteoporosis en mujeres con bajo riesgo de fractura (sobreuso) puede conducir a sobrediagnóstico, tratamiento inapropiado y medicalización. El objetivo de este trabajo fue determinar la proporción de mujeres de 45 a 64 años afiliadas a un plan de medicina prepaga de Buenos Aires...

Salud ósea en pacientes sometidos a trasplante de precursores hematopoyéticos: un nuevo problema a considerar

Rev. méd. Chile; 144 (9), 2016
Background: Patients undergoing hematopoietic cell transplantation (HCT) are at increased risk of developing osteoporosis. Aim: To determine the frequency and severity of Vitamin D deficiency, secondary hyperparathyroidism and low bone mass in patients undergoing HCT. Patients and Methods: Analysis of th...
