1. Expression of Osteopontin mRNA During Periodontal Healing Following Scaling and Root Planing
Abstract Objective: To analyze osteopontin mRNA expression levels in subjects with periodontitis prior to (baseline) and 7, 14, and 28 days following scaling and root planing (SRP). Material and Methods: Gingival crevicular fluid was collected as clinical samples from four subjects with periodontitis (pocket depth, 4-5 mm) aged 35-54 years old as well as f

2. Comparison of apical periodontitis repair in endodontic treatment with calcium hydroxide-dressing and aPDT
Abstract This study evaluated the effect of antimicrobial photodynamic therapy (aPDT) on the endodontic treatment of apical periodontitis (AP). AP was induced in 48 premolars of 6 dogs. After biomechanical preparation, the teeth were divided into 4 groups: Calcium-Hydroxide (CH)/120d and CH/180d: root canals filled with CH-based dressing for 15 days before o

3. The influence of Aloe vera with mesenchymal stem cells from dental pulp on bone regeneration: characterization and treatment of non-critical defects of the tibia in rats
Abstract Objective This study aimed to evaluate the inflammatory effect and bone formation in sterile surgical failures after implantation of a collagen sponge with mesenchymal stem cells from human dental pulp (hDPSCs) and Aloe vera. Material and Methods Rattus norvegicus (n=75) were divided into five experimental groups according to treatment: G1) contr

5. Effect of low power laser in biomodulation of cultured osteoblastic cells of Wistar rats
Abstract Purpose: To analyze aspects of the biomodulating effect of light in biological tissues, bone cells from surgical explants of the femur of rats were irradiated with low intensity laser. Methods: Bone cells were cultured and irradiated with LASER light (GaAlAs). Growth, cell viability, mineralized matrix formation, total protein dosage, immunostim

6. Effects of the photobiomodulation using different energy densities on the periodontal tissues under orthodontic force in rats with type 2 diabetes mellitus
Abstract To evaluate the impact of the GaAlAs diode laser with energy densities of 160 J/cm2, 320 J/cm2, and 640 J/cm2 on the periodontal tissues under continuous orthodontic force application and on the rate of orthodontic tooth movement in rats with type-2 diabetes mellitus. The intensity of primary alveolar bone formation was also investigated through the

7. Combined effects of melatonin and FGF-2 on mouse preosteoblast behavior within interconnected porous hydroxyapatite ceramics - in vitro analysis
ABSTRACT Objective Biocompatible materials such as interconnected porous hydroxyapatite ceramics (IP-CHA) loaded with osteogenic cells and bioactive agents are part of an evolving concept for overcoming craniofacial defects by use of artificial bone tissue regeneration. Amongst the bioactive agents, melatonin (MEL) and basic fibroblast growth factor (FGF-2

8. Nefropatia crônica por ciclosporina : papel do ácido úrico e do sistema renina angiotensina aldosterona como mediadores de disfunção endotelial, inflamação e vasculopatia / Cyclosporine nephropathy : effect of uric acid and the renin angiotensin aldosterone system as mediators of endothelial dysfunction, inflammation vasculopathy
Chronic allograft nephropathy is characterized by stripped tubular atrophy and interstitial fibrosis, in presence of arteriolar hyalinosis, resembling an ischemic pattern of chronic kidney disease. Chronic ischemia is associated with reduced glomerular filtration rate, and increase in serum uric acid levels. Cyclosporine per se also has a direct effect on tu

9. Oxidative nanopatterning of titanium surfaces promotes production and extracellular accumulation of osteopontin
A interface osso-implante é caracterizada pela presença de uma camada de matriz extracellular (MEC) afibrilar rica em proteínas não-colágenas, incluindo osteopontina (OPN), cujas funções no tecido ósseo estão relacionadas à adesão celular e ao controle do processo de mineralização da MEC (crescimento de cristais). Aspectos físicos e químicos d

10. Polymorphisms in MUC1 and osteopontin genes in Nelore heifers / Polimorfismos dos genes MUC1 e Osteopontina em novilhas da raça Nelore (Bos taurus indicus)
MUC1 (MUC1) and osteopontin (SPP1) are glycoproteins expressed in the uterine luminal surface with predict functions in protection and cell adhesion. MUC1 has anti-adhesive role and osteopontin has adhesive role. The expression of both molecules is regulated by the steroid hormone, progesterone. During the receptive period for embryo implantation in the uter

11. Osteopontin is produced by rat cardiac fibroblasts and mediates A(II)-induced DNA synthesis and collagen gel contraction.
Angiotensin II (AII) is a critical factor in cardiac remodeling which involves hypertrophy, fibroblast proliferation, and extracellular matrix production. However, little is known about the mechanism by which AII accelerates these responses. Osteopontin is an acidic phosphoprotein with RGD (arginine-glycine-aspartate) sequences that are involved in the vascu

12. Diffuse calcification in human coronary arteries. Association of osteopontin with atherosclerosis.
Coronary atherosclerosis is frequently associated with calcification of arterial plaque. To understand the mechanisms responsible for the formation of atherosclerotic calcification, we examined human coronary arteries for the presence and extent of mineral. In sections stained specifically for mineral, staining was diffuse and present in all atherosclerotic
