1. Prevalence and clinical characteristics of X-linked hypophosphatemia in Paraná, southern Brazil
ABSTRACT Objective: The aim of this cross-sectional study was to estimate the prevalence of XLH in Paraná, a state in southern Brazil, and report the clinical features and complications of the disease. Materials and methods: We invited all endocrinologists (n = 205), nephrologists (n = 221), orthopedic surgeons (n = 1020), and pediatricians (n = 1000) in

2. Updating the role of matrix metalloproteinases in mineralized tissue and related diseases
Abstract Bone development and healing processes involve a complex cascade of biological events requiring well-orchestrated synergism with bone cells, growth factors, and other trophic signaling molecules and cellular structures. Beyond health processes, MMPs play several key roles in the installation of heart and blood vessel related diseases and cancer, ran

3. Ultrasound of entheses in ankylosing spondylitis patients: The importance of the calcaneal and quadriceps entheses for differentiating patients from healthy individuals
OBJECTIVES: To compare the ultrasonographic findings of entheses in ankylosing spondylitis (AS) patients with those of healthy control individuals and to assess the ability of ultrasound (US) to identify aspects related to the disease. METHODS: A cross-sectional study involving 50 patients with AS and 30 healthy controls was performed. Clinical assessment

4. Root perforations: a review of diagnosis, prognosis and materials
Abstract: Root perforation results in the communication between root canal walls and periodontal space (external tooth surface). It is commonly caused by an operative procedural accident or pathological alteration (such as extensive dental caries, and external or internal inflammatory root resorption). Different factors may predispose to this communication,

5. Elevated levels of plasma osteoprotegerin are associated with all-cause mortality risk and atherosclerosis in patients with stages 3 to 5 chronic kidney disease
Osteoprotegerin (OPG) regulates bone mass by inhibiting osteoclast differentiation and activation, and plays a role in vascular calcification. We evaluated the relationship between osteoprotegerin levels and inflammatory markers, atherosclerosis, and mortality in patients with stages 3-5 chronic kidney disease. A total of 145 subjects (median age 61 years, 6

6. Calcification in vitro of biomineralizated nanohydroxyapatite/superydrophilic vertically aligned multiwalled carbon nanotube scaffolds
Nanocomposites based on superhydrophilic vertically aligned multi-walled carbon nanotubes (VAMWCNT-O2) and nanohydroxyapatite (nHAp) are of great interest in bone regenerative medicine. The biomineralization using simulated body fluid (SBF) has been extensively studied to evaluate the bioactivity of biomaterials. Thus, the combination of nHAp and VAMWCNT-O2

7. Tissue transglutaminase (TG2) activity regulates osteoblast differentiation and mineralization in the SAOS-2 cell line
Tissue transglutaminase (type II, TG2) has long been postulated to directly promote skeletal matrix calcification and play an important role in ossification. However, limited information is available on the expression, function and modulating mechanism of TG2 during osteoblast differentiation and mineralization. To address these issues, we cultured the well-

8. Avaliação de calcificação vascular e osteoporose em uma população de indivíduos com 65 anos ou mais na área do Butantã / Assessment of vascular calcification and osteoporosis in a population of individuals aged 65 years or more in Butantã
O objetivo deste trabalho foi avaliar a associação de calcificação da aorta abdominal (CAA) com marcadores do metabolismo ósseo: densidade mineral óssea (DMO), dados laboratoriais (cálcio, fósforo, 25OH-vitamina D, PTH) e clínicos em uma população brasileira de idosos. Este foi um estudo de corte transversal onde foram incluídos 815 indivíduos c

9. Clinical and radiographic study of the morphology of the stylohyoid complex in patients with Temporomandibular Disorders and Orofacial Pain. / Estudo clínico e radiográfico dos aspectos morfológicos da cadeia estilo-hióidea em sujeitos com disfunção temporomandibular e dor orofacial
The relationship between temporomandibular disorders and Eagle\ s syndrome occurs due to the similarity of symptoms. The knowledge gained about the Eagle\ s syndrome shows that its symptoms can be very easily confused with other types of craniomandibular disorders and numerous other diseases found in regions of the skull, face and neck. The lack of informati

10. Proteoliposomes as matrix vesicles' biomimetics to study the initiation of skeletal mineralization
During the process of endochondral bone formation, chondrocytes and osteoblasts mineralize their extracellular matrix by promoting the formation of hydroxyapatite (HA) seed crystals in the sheltered interior of membrane-limited matrix vesicles (MVs). Ion transporters control the availability of phosphate and calcium needed for HA deposition. The lipidic micr

11. Associated factors to occurrence of pulp necrosis in traumatized primary incisors / Fatores relacionados à ocorrência de necrose pulpar em incisivos decíduos traumatizados
The purpose of this historical cohort study was to assess dental trauma in primary upper incisors and factors associated with the occurrence of pulp necrosis in traumatized primary upper central incisors. Data was collected by a single examiner through the analysis of photographs, radiographs, and information contained in the clinical files of patients who a

12. Petroleum ether extract of Cissus quadrangularis (Linn.) enhances bone marrow mesenchymal stem cell proliferation and facilitates osteoblastogenesis
OBJECTIVE: To evaluate the effects of the petroleum ether extract of Cissus quadrangularis on the proliferation rate of bone marrow mesenchymal stem cells, the differentiation of marrow mesenchymal stem cells into osteoblasts (osteoblastogenesis) and extracellular matrix calcification. This study also aimed to determine the additive effect of osteogenic medi
