1. Association between bone mineral density and content and physical growth parameters among children and adolescents diagnosed with HIV: a cross-sectional study
ABSTRACT BACKGROUND: During childhood and adolescence, there are significant increases in bone mineral content (BMC) and bone mineral density (BMD). OBJECTIVE: To investigate physical growth parameters associated with BMD and BMC among children and adolescents diagnosed with human immunodeficiency virus (HIV). DESIGN AND SETTING: Cross-sectional study con

2. Celiac disease and bone
Abstract Celiac disease (CD) is an autoimmune disorder characterized by small intestinal inflammation triggered by gluten ingestion in genetically-predisposed individuals. A frequent extra-intestinal manifestation of CD is metabolic bone disease which contributes to an increased risk of fracture. The mechanisms underlying bone disease in CD remain incomplete

3. Association between handgrip strength and bone mass parameters in HIV-infected children and adolescents. A cross-sectional study
ABSTRACT BACKGROUND: Low bone mineral content (BMC) and bone mineral density (BMD) have been identified in human immunodeficiency virus (HIV)-infected children and adolescents. The direct adverse effects of HIV infection and combined antiretroviral therapy (ART) negatively contribute to bone metabolism. A direct relationship between muscle strength levels a

4. Osteopenia and osteoporosis among treatment-experienced people living with HIV
Abstract Introduction Life expectancy of people living with human immunodeficiency (PLHIV) has increased mainly due to the accessibility and effectiveness of antiretroviral therapy (ART). However, adverse effects from long-term use of antiretrovirals, and the physiological changes associated with aging, may compromise the quality of life of PLHIV, in additi

5. Modeling and prediction of sulfuric acid digestion analyses data from PXRF spectrometry in tropical soils
ABSTRACT Sulfuric acid digestion analyses (SAD) provide useful information to environmental studies, in terms of the geochemical balance of nutrients, parent material uniformity, nutrient reserves for perennial crops, and mineralogical composition of the soil clay fraction. Yet, these analyses are costly, time consuming, and generate chemical waste. This wor

6. Milk consumption, dietary calcium intake and nutrient patterns from adolescence to early adulthood and its effect on bone mass: the 1993 Pelotas (Brazil) birth cohort
O estudo teve como objetivo avaliar o consumo de leite, a ingestão dietética de cálcio e os padrões de nutrientes (favoráveis e desfavoráveis à saúde óssea) do final da adolescência até o início da idade adulta sobre a massa óssea aos 22 anos de idade. Foram realizadas análises transversais em 3.109 participantes da coorte de nascimentos de 199

7. The influence of nitrogen to hydrogen ratio and temperature on thickness and phase composition in plasma nitrided Ti-6Al-4V
ABSTRACT Ti-6Al-4V was plasma nitrided using several N2/H2 ratios and substrate temperatures. In order to investigate the combined influence of these parameters on phase composition and thickness of the coatings, the phases in the as received, annealed, and nitrided Ti-6Al-4V samples were identified with Rietveld refinement. In the as-received and annealed s

8. PREVALENCE OF EARLY SPINAL DEFORMITY IN CHILDREN WITH GMFCS V CEREBRAL PALSY
RESUMO Objetivo: A Paralisia Cerebral espástica (PCe) é uma das causa de escoliose precoce,, embora não existam dados da prevalência. Nosso objetivo foi determinar a prevalência das deformidades espinhais (DE) neuromusculares de início precoce em crianças PCe severamente comprometidas. Métodos: Estudo quantitativo transversal, exploratório e descr

9. Can heat-pressed feldspathic ceramic be submitted to multiple heat-pressing?
Abstract The aim of this study was to determine if multiple processing (heat-pressing) of a dental ceramic influences flexural strength, hardness, and microstructure. Ninety bar-shaped specimens (15 mm × 4 mm × 2 mm) of a pressed ceramic (Vita PM9) were fabricated and randomly divided into 6 groups (n = 15) according to the factors “number of pressings�

10. Synthesis and characterization of lithiated nanostructures
ABSTRACT Regardless of the simple accumulation of ions in the crystal insertion sites, nanomaterials offer a new storage mechanism of lithium ions (Li+), these storage mechanisms are formed in the interfaces and inside of the nanopores. Such kinds of storage mechanisms have no effect on the structure of the electrode material. Consequently, the charge-discha

11. Dislocation Density and Texture in Copper Deformed by Cold Rolling and Ecap
Analysis of dislocation density in metallic materials has been pursued with great interest for many years because dislocations are closely associated with plastic deformation and thus exert a deep effect on the mechanical properties of any material. Crystallographic texture has also a decisive influence in some properties. In this work, the dislocation densi

12. Confocal Fluorescence Microscopy and Kinetics of the Cr 3+-Chromate Ion Oxidation Equilibria at the Solid Liquid Interface
Silica-borax pearl samples impregnated with 0.17 and 0.64% Cr3+ were characterized by specific surface area measurements, UV-Vis spectroscopy, energy-dispersive X-ray fluorescence and laser-scanning confocal microscopy. Pearl stability against oxidizing conditions was tested by adding samples to an aqueous hydrogen peroxide solution. The reaction was examine
