1. Controversies in the treatment of postmenopausal osteoporosis: How long to treat with bisphosphonates?
ABSTRACT Osteoporosis is a systemic skeletal disease characterized by reduced bone mass and deterioration of bone tissue microarchitecture leading to an increased risk of fractures. Fragility fractures, especially hip fractures, are associated with a significant reduction in the physical function and quality of life of affected patients, as well as increased

3. Investigation of chromosomal alterations in patients with Alzheimer's disease in the state of Amazonas, Brazil
RESUMO Doença de Alzheimer (DA) tem como principal característica a deterioração das funções cerebrais. Quanto a sua etiologia ainda é complexa e indefinida, apesar do progresso alcançado na compreensão de seus mecanismos neurológicos, infecciosos, bioquímicos, genéticos e citogenéticos. Considerando isto, nós investigamos a presença de altera

4. The natural history of solitary post-nephrectomy kidney in a pediatric population
ABSTRACT Introduction: Children with a solitary post-nephrectomy kidney (SNK) are at potential risk of developing kidney disease later in life. In response to the global decline in the number of nephrons, adaptive mechanisms lead to renal injury. The aim of this study was to determine the prevalence and time of onset of high blood pressure (HBP), proteinuri

5. Investigating the Effect of Curing in the Chloride Diffusion Coefficient of Conventional Concrete
Concrete is the most used material in the construction industry worldwide. Built concrete infrastructure is exposed to specific environments conditions during the asset’s life, which impose chemical and physical actions that may lead to premature deterioration. Poor concrete durability and corrosion of reinforcement bars are the primary cause of structural

6. Mechanical and Durability Performance of Polyacrylonitrile Fiber Reinforced Concrete
In this paper, the impact toughness, autogenous shrinkage, chloride penetration resistance, permeability resistance and abrasion resistance performance of prepared concrete reinforced with Polyacrylonitrile fiber (PAN fiber) were researched. The PAN fiber volume concentration percentages of cement were 0, 0.5%, 1.0%, 1.5% and 2.0%, respectively. The results

8. Effect of different durations of overdistention on rat bladder function and morphology
We investigated the contribution of the duration of overdistention (DOD) to rat bladder function and morphology and explored its possible molecular mechanisms. Bladder overdistention was induced in male Sprague-Dawley rats (200-250 g) by an infusion of saline. Forty rats were divided into 5 groups submitted to different DOD, i.e., 1, 2, 4, and 8 h, and contr

9. Microbial deterioration of vacuum-packaged chilled beef cuts and techniques for microbiota detection and characterization: a review
Gas production from microbial deterioration in vacuum-packs of chilled meat leads to pack distension, which is commonly referred as blown pack. This phenomenon is attributed to some psychrophilic and psychrotrophic Clostridium species, as well as Enterobacteria. The ability of these microorganisms to grow at refrigeration temperatures makes the control by th

12. Avaliação do impacto da redução de pressão nas perdas reais em setor de distribuição de água do municipio de Campo Grande MS / Impact of reduction of pressure losses in real sector of water supply of the municipality of Campo Grande MS
The losses in a system of water supply may represent a large percentage of the total water supplied, depending on age, the applied pressure and the deterioration of the system. This paper presents the water losses occurring in water supplies and various control mechanisms available to avoid them. The aim is to correlate the loss of a real system and the same
