OBJECTIVES We assessed the agreement of body fat and fat-free mass measured by simpler methods against the four-compartment model (4C). METHODS In 60 obese schoolchildren (body mass index ≥95th percentile) between the ages of 8 and 13 y who were recruited from one school in Chile, multicompartmental body composition was estimated with the use of isotopic dilution, plethysmography (BodPod), ra...

Introdução: Os desportos de combate referem-se a um conjunto modalidades individuais grande relevância no cenário desportivo mundial. A maioria dos é classificado por categorias peso, como tal, os atletas tendem reduzir ao máximo sua massa gorda e mesmo corporal para competir nas peso mais baixas. Objetivos: Compreender importância da DEXA na avaliação composição em combate. Metodologia: Foi re...

BACKGROUND Dunnigan type Familial Partial Lipodystrophy (FPLD) is characterized by loss of subcutaneous fat from the limbs and excessive accumulation on the visceral adipose tissue (VAT). Affected individuals have insulin resistance (IR), diabetes, dyslipidemia and early cardiovascular (CV) events, due to their imbalanced distribution of total body fat (TBF). Epicardial adipose tissue (EAT) is ...

introduction: mandibular fracture is the most common facial bone fracture due to facial trauma. a variety of imagings have been used for diagnosis of mandibular fractures. however, the choice of imaging for diagnosis of mandibular fractures is controversial.present study compares the accuracy of the three most common imaging methods in mandibular fracture diagnosis panoramic radiography, corona...

Dual-energy X-ray absorptiometry (DXA) in single energy mode has been shown to permit the visualisation of bone and soft tissue, such as patellar tendon through two-dimensional sagittal imaging. However, there is no validated DXA-based measurement Achilles moment arm (dAT). The aims this study were: 1) compare vivo DXA derived measurements dAT at rest against two previously methods: excursion (...

The aim of this study was to further explore the use of magnetic resonance imaging (MRI), magnetic resonance angiography (MRA), and dual-energy X-ray absorptiometry (DEXA) to assess bone formation and blood circulation in a pedicled bone graft substitute. In 14 Wistar rats, initially 10 weeks old, heterogeneous demineralized femur bone matrix implants were wrapped in pedicled adductor thigh mus...

In the rat, urinary concentrating ability develops progressively during the third postnatal (P) week and nearly reaches adult level at weaning (P21) governed by a rise in circulating glucocorticoid. Elevated extracellular osmolality can lead to growth arrest of epithelial cells. We tested the hypothesis that supranormal exposure of rat pups to glucocorticoid before the endogenous surge enhances...

We developed and tested a novel method for perfusing parts of human liver to study uptake and handling of drug-targeting preparations. These preparations, designed for the treatment of liver fibrosis in man, have been extensively studied in animals, but little is known about the uptake and handling by human livers. Human liver tissue was obtained from livers procured from multiorgan donors and ...
