Repair of Bone Defects with Chitosan-Collagen Biomembrane and Scaffold Containing Calcium Aluminate Cement

Braz. dent. j; 28 (3), 2017
Abstract Innovative biomaterials can provide a promising new direction for the treatment of bone defects, stimulating a proper repair process, with no damage to adjacent tissues. The purpose of this in vivo study was to evaluate the biocompatibility and the osteoinductive capacity of chitosan-collagen bi...

Somatic maturation and the relationship between bone mineral variables and types of sports among adolescents: cross-sectional study

Säo Paulo med. j; 135 (3), 2017
ABSTRACT CONTEXT AND OBJECTIVE: Peak height velocity (PHV) is an important maturational event during adolescence that affects skeleton size. The objective here was to compare bone variables in adolescents who practiced different types of sports, and to identify whether differences in bone variables att...

Reassessment and Relationships of Scutatuspinosus itapagipensis (Teleostei, Clupeomorpha, Ellimmichthyiformes) from the Neocomian of Recôncavo Basin, Northeastern Brazil

An. acad. bras. ciênc; 89 (2), 2017
ABSTRACT Clupeomorphs are found in many assemblages of the northeastern Brazil, whose ages range from the Neocomian to Paleogene. Ten species were described. Among them †Scutatuspinosus itapagipensis, a torpedo-like fish found in shales of the Marfim Formation from Bahia, remains poorly known. At f...

Effects of the use of growth hormone in children and adolescents with juvenile idiopathic arthritis: a systematic review

Rev. bras. reumatol; 57 (2), 2017
Abstract Introduction: Children with juvenile idiopathic arthritis (JIA) often have impaired growth and short stature. There is evidence that the therapeutic use of growth hormone (GH) is useful and safe in these patients. Objective: To analyze the effects of GH use in patients with JIA. Method: A sys...

Hepatic Osteodystrophy: The Mechanism of Bone Loss in Hepatocellular Disease and the Effects of Pamidronate Treatment

Clinics; 72 (4), 2017
OBJECTIVES: The present study was designed to evaluate the bone phenotypes and mechanisms involved in bone disorders associated with hepatic osteodystrophy. Hepatocellular disease was induced by carbon tetrachloride (CCl4). In addition, the effects of disodium pamidronate on bone tissue were evaluated. ...

Lamivudine, Entecavir, or Tenofovir Treatment of Hepatitis B Infection: Effects on Calcium, Phosphate, FGF23 and Indicators of Bone Metabolism

Ann. hepatol; 16 (2), 2017
ABSTRACT Background. Patients with chronic hepatitis B virus (HBV) are often treated with nucleoside/nucleotide antiviral agents and metabolic bone toxicity is a possible concern. Objective. To determine the relationships between fibroblast growth factor 23 (FGF23), a phosphaturic hormone, bone miner...

Osteosíntesis mínimamente invasiva con tornillos centromedulares canulados para fracturas de metacarpianos

Acta ortop. mex; 31 (2), 2017
Resumen: Antecedentes: Las fracturas de los metacarpianos comprenden de 18 a 44% de las fracturas de la mano. La mayoría de las fracturas simples de cuello y transversales diafisiarias de metacarpianos pueden ser tratadas de manera conservadora con buenos resultados. Sin embargo, en el caso de fractur...

Marcadores de formación y resorción ósea y su utilidad para determinar el final del periodo de aposición ósea
Bone formation and resorption markers to evaluate the end of bone apposition

Actual. osteol; 13 (1), 2017
El pico de masa ósea (PMO) se alcanza entre los 20 y 35 años, pero la aposición ósea continúa hasta alcanzar el pico de fortaleza ósea (PFO). Se crea así una ventana entre ambos picos que podría ser evaluada mediante marcadores bioquímicos de recambio óseo, ya que durante dicho período la dens...

Osseointegration of titanium implants anodized with and without fluoride in the electrolyte: a study in rats

Actual. osteol; 13 (1), 2017
Based on the hypothesis that fluoride acts as a bone anabolic agent, the aim of this study was to measure in rats the osseointegration of implants (grade II titanium wire, 1 mm diameter, 4 mm long) submitted to anodic oxidation in 2 M phosphoric acid solution (control implants) or b) in 2 M phosphoric ac...
