Objective(s): Electrospun nanofibrous mats of poly(lactic acid) (PLA) and nanohydroxyapatite (nano-HA) were prepared and proliferation and differentiation of mesenchymal stem cells on the prepared nanofibers were investigated in this study. Materials and Methods: PLA/nano-HA nanofibers were prepared by electrospinning. The effects of process parameters, such as nano-HA concentration, distance, ...

The sustainability of the built environment is increasingly coming to the forefront of infrastructure design and maintenance decisions. To address this, development of a new class of more sustainable cement-based materials is needed. Fiber reinforced self-consolidating mortar (FRSCM) was developed by optimizing the micromechanical parameters, which control composite properties in the hardened s...

Background and Objectives: Increased consumption of fiber in the diet of diabetic patients is usually recommended for better diabetes control. Trans-theoretical model of health behavior has had positive results in diabetes consultations on healthcare and adherence to healthy eating. The present study aimed to investigate the relationship between the stages of change based on fiber consumption a...

A model has been formulated for analyzing the influence of fiber inclination angle on its rupture load in fiber reinforced cementitious composite. As a stiff fiber is pulled with an angle to the direction of pulling, the fiber rupture load decreases compared to the case with zero inclination angles. This phenomenon is called fiber apparent strength (defined as rupture load divided by fiber cros...

the purpose of this ex- vivo study was to evaluate the fracture resistance of simulated immature teeth, obturated with gutta-percha or resilon and reinforced by either composite resin or fiber post.eighty-four human maxillary incisors were divided into seven groups (n=12). teeth in all groups were prepared until peeso #5 (1.5mm) could be passed through the apex. root ends received 4mm of mta pl...

objective: there is no definitive data on the strength of glass fiber and cast posts with different length. this in vitro study was designed to investigate and compare the effect of length on the retentive strength of glass fiber and cast posts. materials and methods: sixty recently extracted intact maxillary canine teeth were cut 1mm above the cej. the specimens were endodontically treated and...

Lignin fibers typically influence the mixture performance of stone matrix asphalt (SMA), such as strength, stability, durability, noise level, rutting resistance, fatigue life, and water sensitivity. However, limited studies were conducted to analyze the influence of fibers on the percent voids in mineral aggregate in bituminous mixture (VMA) during the mixture design. This study analyzed the e...

introduction: the aim of the present study was to evaluate the effect of high fiber diet on lipid profile of obese adolescent girls. methods: this randomized cross over clinical trial was conducted in southern iran. a total of 56 patients were randomly assigned into two groups. in the first phase, the experiment group had a high fiber diet while the control group consumed their usual diet for 2...
