Abstract: El objetivo de este estudio fue evaluar la densidad mineral ósea (DMO) y el contenido mineral óseo (CMO) de los segmentos corporales durante un periodo de entrenamiento de seis meses. Se evaluaron a 41 futbolistas juveniles profesionales en dos momentos, una al comienzo (TI) y otra al final (TF) de la intervención con el equipo de absorciometría dual de rayos X (DEXA). Se lograron aumentos significativos en la DMO en los segmentos corporales de la cadera, columna lumbar, triangulo de Ward, tronco y del cuerpo total (p<0.05). También se obtuvo un incremento significativo del CMO en la cadera, columna lumbar, pierna, tronco y costillas (p<0.05). El entrenamiento de futbol fortaleció el CMO y la DMO del hueso de la extremidad inferior y de la caja torácica, con lo cual el fútbol podría ser una actividad útil para la mejorar la mineralización y fortalecimiento del hueso, para prevenir lesiones y fracturas

The objective of this study was to assess bone mineral density (BMD) and bone mineral content (BMC) of body segments for a six months training period. 41 professional youth players were evaluated in two moments, one at the beginning (TI) and another at the end (TF) of the intervention with the dual energy x-ray absorptiometry equipment (DEXA). Significant increases in BMD were achieved in the body segments of the hip, lumbar spine, ward triangle, trunk and total body (p <0.05). There was also a significant increase in BMC in the hip, lumbar spine, leg, trunk and ribs (p <0.05). Soccer training strengthened the BMC and BMD of the lower limb bone and the rib cage, which could be a useful activity to improve bone mineralization and strengthening, to prevent injuries and fractures

Title: Silver-loaded nanoparticles affect ex-vivo mechanical behavior and mineralization of dentin
Source: Med. oral patol. oral cir. bucal (Internet);24(2):e156-e164, mar. 2019. tab, ilus, graf.
Language: en.
Abstract: Background: The aim was to evaluate the effect of silver loaded nanoparticles (NPs) application on the triboscopic, crystallographic and viscoelastic properties of demineralized dentin. Polymethylmetacrylate-based NPs and Ag loaded NPs were applied on demineralized dentin. Material and Methods: Treated and untreated surfaces were probed by a nanoindenter to test viscoelasticity, and by atomic force microscopy to test nanoroughness and collagen fibril diameter. X-ray diffraction and transmission electron microscopy through selected area diffraction and bright-field imaging were also used. Results: Dentin treated with Ag-NPs attained the lowest complex modulus, and the highest tan delta values after 7 days of storage. Dentin treated with undoped-NPs achieved the lowest nanoroughness and the greatest collagen bandwidths among groups. Crystals were identified as hydroxyapatite with the highest crystallographic maturity and crystallite size in dentin treated with undoped-NPs. Texture increased in all samples from 24 h to 7 d, except in dentin surfaces treated with Ag-NPs at 310 plane. Polyhedral, block-like, hexagonal or plate-like shaped apatite crystals constituted the bulk of minerals in dentin treated with Ag-NPs, after 7 d. Polyhedral or rounded/drop-like, and polymorphic in strata crystal apatite characterized the minerals when undoped-NPs were used, with more crystalline characteristics after 7 d than that found when Ag-NPs were applied. Ag-NPs application did not improve the mechanical performance of dentin and did not produce dentin remineralization. However, energy was dissipated through the dentin without showing stress concentration; contrary was occurring at dentin treated with undoped- NPs, that provoked bridge-like mineral deposits at the dentin surface. Conclusions: Ag-NPs application did not enhance the mechanical properties of cervical dentin, though the energy dissipation did not damage the dentin structure. Remineralization at dentin was not produced after Ag-NPs appli-cation, though improved crystallinity may lead to increase stability of the apatite that was generated at the dentin surface

Abstract: Background: The purpose of this study was to evaluate nanohardness and viscoelastic behavior of dentin surfaces treated with two canal sealer cements for dentin remineralization. Material and Methods: Dentin surfaces were subjected to: I) 37% phosphoric acid (PA) or II) 0.5 M ethylenediaminetetraacetic acid (EDTA) conditioning prior to the application of two experimental hydroxyapatite-based cements, containing sodium hydroxide (calcypatite) or zinc oxide (oxipatite), respectively. Samples were stored in simulated body fluid during 24 h or 21 d. The intertubular and peritubular dentin were evaluated using a nanoindenter to assess nanohardness (Hi). The load/displacement responses were used for the nano-dynamic mechanical analysis to estimate complex modulus (E*) and tan delta (δ). The modulus mapping was obtained by imposing a quasistatic force setpoint to which a sinusoidal force was superimposed. AFM imaging and FESEM analysis were performed. Results: After 21 d of storage, dentin surfaces treated with EDTA+calcypatite, PA+calcypatite and EDTA+oxipatite showed viscoelastic discrepancies between peritubular and intertubular dentin, meaning a risk for cracking and breakdown of the surface. At both 24 h and 21 d, tan δ values at intertubular dentin treated with the four treatments performed similar. At 21 d time point, intertubular dentin treated with PA+oxipatite achieved the highest complex modulus and nanohardness, i.e., highest resistance to deformation and functional mineralization, among groups. Conclusions: Intertubular and peritubular dentin treated with PA+oxipatite showed similar values of tan δ after 21 d of storage. This produced a favorable dissipation of energy with minimal energy concentration, preserving the structural integrity at the dentin surface

Title: Aterosclerosis y hematopoyesis clonal: un nuevo factor de riesgo / Atherosclerosis and clonal hematopoyesis: A new risk factor

Abstract: Investigaciones realizadas en los últimos años han demostrado que la hematopoyesis clonal de potencial indeterminado (CHIP), resultado de mutaciones somáticas en células madre, no es solo un proceso relacionado con la edad y un estado premaligno, sino una condición que predispone al desarrollo de enfermedades cardiovasculares. La presencia de mutaciones DNMT3A, TET-2 y ASXL1 en células hematopoyéticas se ha asociado con un riesgo elevado de cardiopatía e ictus isquémicos, así como con elevada calcificación coronaria. CHIP emerge como un nuevo factor de riesgo de enfermedad aterosclerótica y su detección puede tener importantes implicaciones terapéuticas para modificar la historia natural de la enfermedad

Recent research has revealed that clonal hematopoyesis of indeterminate potential (CHIP) characterized by the acquisition of somatic mutations in hematopoietic stem cells, is not only a common age-related disorder and a premalignant condition, but it is also associated with the development of atherosclerotic vascular diseases. Mutations in DNMT3A, TET2 and ASXL1 were each individually associated with coronary heart disease, stroke and coronary calcification. Therefore, CHIP emerges as a new risk factor for atherosclerotic vascular pathologies and its detection may be relevant as a new therapeutic target in order to modify the natural course of the disease

Abstract: Introduction: intake of diets with high saturated fat may produce deleterious effects on bone mineralization. Lifestyle changes help reduce the bone loss observed in osteoporosis. Resveratrol, present in grape juice and red wine, has osteogenic and osteoinductive effects, being potentially beneficial for bone health. Objective: to evaluate the effects of red grape juice, red wine and resveratrol consumption on bone parameters in Wistar rats submitted to a high-fat diet and physical training. Method: female Wistar rats, with 90 days of age, were divided into five groups and followed up for 60 days: a) control group; b) high-fat group; c) grape juice group; d) red wine group; and e) resveratrol group. The different groups of animals performed a physical training protocol. Animal's weight and consumption were monitored weekly. After 60 days, femoral dimensions, bone mineral density (BMD) and bone mineral content (BMC) were evaluated. Results: there was no difference in body mass; however, all groups consuming the high-fat diet had higher consumption (p < 0.05). RWG presented a greater distance between the epiphyses, femoral mass and BMC (p < 0.05). RWG and RG presented greater mean diaphysis point width and BMD (p < 0.05). Conclusion: the results suggest that the bioactive compounds present in red wine and resveratrol solution together with regular exercise were able to promote beneficial effects on bone health, even when associated with a high saturated fat diet

Introducción: el consumo de dietas ricas en grasas saturadas puede producir efectos nocivos sobre la mineralización ósea. Los cambios en el estilo de vida ayudan en la reducción de la pérdida ósea que se produce en la osteoporosis. El resveratrol, presente en el zumo de uva y el vino tinto, tiene efectos osteogénicos y osteoinductores, y es potencialmente beneficioso para la salud ósea. Objetivo: evaluar los efectos del consumo de zumo de uva roja, vino tinto y resveratrol sobre los parámetros óseos en ratas sometidas a una dieta alta en grasa y entrenamiento físico. Métodos: ratas Wistar, hembras, con 90 días, fueron divididas en cinco grupos y monitorizadas durante 60 días: a) grupo de control; b) grupo hiperlipidemia; c) grupo zumo de uva roja; d) grupo de vino tinto; y e) grupo de resveratrol. Los distintos grupos de animales fueron sometidos a un protocolo de entrenamiento físico. El peso y el consumo de los animales se monitorizaron semanalmente. Después de 60 días, se evaluaron el tamaño del fémur, la densidad mineral ósea (DMO) y el contenido mineral óseo (CMO). Resultados: no hubo diferencias en el consumo, sin embargo, todos los grupos que consumieron la dieta rica en grasas tenían un mayor consumo (p < 0,05). GV tenía una mayor distancia entre las epífisis, mayor tamaño del fémur y un mayor CMO (p < 0,05). SGS y GR tenía mayor anchura media de diáfisis y una mayor DMO (p < 0,05). Conclusión: Los resultados sugieren que los compuestos bioactivos presentes en el vino tinto y la solución de resveratrol, combinados con el ejercicio físico regular, fueron capaces de promover efectos beneficiosos sobre la salud ósea, incluso cuando se asocian con una dieta alta en grasas saturadas

Title: Production of bone mineral material and BMP-2 in osteoblasts cultured on double acid-etched titanium
Source: Med. oral patol. oral cir. bucal (Internet);22(5):e651-e659, sept. 2017. ilus, tab.
Language: en.
Abstract: Background: The study of osteoblasts and their osteogenic functions is essential in order to understand them and their applications in implantology. In this sense, this study try to study BMP-2 production and bone matrix deposition, in addition to other biological variables, in osteoblasts cultured on a rough double acid-etched titanium surface (Osseotite®, Biomet 3i, Palm Beach Garden, Florida, USA) in comparison to a smooth titanium surface (machined) and a control Petri dish. Material and Methods: An in vitro prospective study. NHOst human osteoblasts from the femur were cultured on three different surfaces: Control group: 25-mm methacrylate dish (n = 6); Machined group: titanium discs with machined surface (n = 6) and Experimental group: titanium discs with a double acid-etched nitric and hydrofluoric Osseotite® acid surface (n = 6). A quantification of the mitochondrial membrane potential, and studies of apoptosis, mobility and adhesion, bone productivity (BMP-2) and cellular bone synthesis were carried out after culturing the three groups for forty-eight hours. Results: A statistically significant difference was observed in the production of BMP-2 between the experimental group and the other two groups (22.33% ± 11.06 vs. 13.10% ± 5.51 in the machined group and 3.88% ± 3.43 in the control group). Differences in cellular bone synthesis were also observed between the groups (28.34% ± 14.4% in the experimental group vs. 20.03% ± 6.79 in the machined group and 19.34% ± 15.93% in the control group). Conclusions: In comparison with machined surfaces, Osseotite® surfaces favor BMP-2 production and bone synthesis as a result of the osteoblasts in contact with it (AU)
