Wear behaviors of silane coated silica (SiO2) nanoparticle-filled glass fiber reinforced polymer composites were investigated depending on the type coating (KH550: -Aminopropyl-triethoxy-silane and KH570: -Methacryloxypropyl-trimethoxy-silane) nanoparticle percentages within matrix. Unlike cases given in most research studies, silanized nanoparticles used as received. Therefore, synergistic ...

Objective: The most essential requirement of a provisional crown is an adequate marginal fit which necessary for maintaining optimal periodontal health and protect the tooth from physical, chemical, thermal, bacterial injuries. purpose this in vitro study was to evaluate compare vertical accuracy materials using four different material systems (Autopolymerized PMMA powder-liquid system, light-a...

This study aimed to explore the histomorphology of pancreatic tissue medaka fish develop as a diabetic animal model. Adult were obtained with body length 2.53±0.22 cm and weight 265.8±25 g. Medaka fixed using Boiun's fixative solution. Macro anatomical observations pancreas conducted stereomicroscope. Histological preparations made according Hematoxylin-eosin staining standard procedure. Pancre...

Microplastics (MPs) affect plankton (a basis of the trophic chain) and planktivorous fish can ingest them through food confusion or by transmission. Consensus to determine MPs in is lacking and, so, three digestion treatments were evaluated: Alkaline (potassium hydroxide) enzymatic (protease plus lipase) digestions, both combined with a hydrogen peroxide stage; an oxidative method using surfact...

Introduction. Molar-incisor hypomineralization (MIH) is a developmental defect of dental enamel that affects one to all four first permanent molars (FPM) and frequently incisors. Enamel aberrations are observed as demarcated opacities different colors (from white brown) posteruptive breakdown. Clinically similar pathological signs can also be present in deciduous molars. Case outline. Histology...

This paper presents an analysis of the morphological and anatomical characteristics aboveground parts (herba) clary sage (Salvia sclarea L.), with emphasis on investigation its surface structures. After procedure primary processing drying plant material, it was determined that composition crushed herbal drug Salviae sclareae herba showed presence leaves, bracts, flowers axis inflorescence, stem...

With its four species, Anchusa is one of the weedy genera of Boraginaceae in Iran. Its species are distributed in different habitats. In this study, the fruit morphological and micro-morphological features of the Anchusa taxa have been considered, so as to evaluate their diagnostic value. Eight qualitative and quantitative fruit features from 12 accessions of A. italica, A. strigosa, A. arvensi...

A study was undertaken to evaluate the effect of artificial aging through steam and thermal treatment as influencing the shear bond strength between three different commercially available zirconia core materials, namely, Upcera, Ziecon, and Cercon, layered with VITA VM9 veneering ceramic using Universal Testing Machine. The mode of failure between zirconia and ceramic was further analyzed as ad...
