In this work, Scanning Electron Microscopy (SEM) has been used to determine the size and morphology of bone mineral crystals obtained from hydrazine-deproteinated parietal bone and femur of Wistar rats aged 15 days, 1 month and 1 year. Apart from the Scanning Electron Microscopy study, crystal size was also determined by X-ray diffractometry, using the Debye- Scherrer equation. Analyzing the results obtained and those reported in the literature for isolated crystals, it is possible to evaluate… Expand

Effect of hydrazine deproteination on bone mineral phase: a critical view.
TLDR
The experimental results obtained in this work, even when compared to the results in the literature, show that most widespread criticism to the hydrazine deproteination process is not completely justified. Expand
Characterization of powdered fish heads for bone graft biomaterial applications.
TLDR
The microstructure of Powder A was mainly composed of different sizes and tubular shape, whereas Powder B showed agglomerated particles, which can be considered as bone graft after transformation to hydroxyapatite phase. Expand
Local electronic structure and nanolevel hierarchical organization of bone tissue: theory and NEXAFS study.
TLDR
The NEXAFS analysis has demonstrated the essential hierarchy induced HAP- to-bone red shifts of the Ca and P 2p-to-valence transitions and described the mechanisms ensuring the link of the hierarchical organization with the electronic structure of the mineralized phase in bone. Expand
Synthesis of Hydroxyapatite-Nanorods with the Effect of Non-Ionic Surfactant as a Drug Carrier for the Treatment of Bone Infections
Hydroxyapatite (HAP) was synthesized using wet chemical method through surfactant assisted route. Microstructural features such as size and morphology of the resulting HAP were studied using Field… Expand

Electrospun fibrous scaffolds combined with nanoscale hydroxyapatite induce osteogenic differentiation of human periodontal ligament cells
TLDR
In this study, COL/PCL/nHA-SBF produced by electrospinning followed by biomimetic mineralization had combined electrospun fibers with nHA in it, indicating that this scaffold had the ability to induce osteogenic differentiation of periodontal ligament cells. Expand
Enhancing the Solubility of Calcium Phosphate Ceramics by Calcium Salt Infiltration for the Purpose of Hematopoietic Stem Cell Culturing
The hematopoietic stem cells (HSCs) have been unquestionably important to therapies that involve blood and immune system replacement. However, the in-vitro culture and the expansion of HSCs inhibit… Expand
Mineralogical transformation during hydroxyapatite dissolution in simple aqueous solutions
Abstract Hydroxyapatite (HAP) is considered to be a stable mineral under surface Earth conditions and adopted as a proxy for paleo-environmental reconstructions and in choice of remediation… Expand

Chemical and structural characterization of the mineral phase from cortical and trabecular bone.
TLDR
X-ray diffraction, infrared spectroscopy and chemical investigations have been carried out on the inorganic phases from rat cortical and trabecular bone, finding differences can be related to the different extents of collagen posttranslational modifications exhibited by the two types of bone, in agreement with their different biological functions. Expand
TEM analysis of the nanostructure of normal and osteoporotic human trabecular bone.
TLDR
It was found that crystals were of platelet shape with irregular edges and that there was no substantial difference in crystal length or crystal thickness between normal and osteoporotic trabecular bone. Expand
Shape and size of isolated bone mineralites measured using atomic force microscopy
TLDR
Using atomic force microscopy, direct three‐dimensional visual evidence is obtained of the size and shape of native protein‐free mineralites isolated from mature bovine bone, providing more accurate inputs to molecular‐scale models aimed at predicting the physiological and mechanical behavior of bone. Expand
Age changes in the crystallinity of bone mineral and in the disorder of its crystal.
TLDR
It is suggested that lattice imperfections of the first kind more largely contributes to the disorder of bone mineral crystals than those of the second kind. Expand
Normal maturational changes in bone matrix, mineral, and crystal size in the rat
TLDR
Normal rat bone maturation has been studied using biochemical methods and hydrazine separation of matrix and mineral for X-ray diffraction and growth in mean crystal size appears to be the determinant of the changing ratios of calcium, magnesium, carbonate, and phosphorus. Expand
Organization of apatite crystals in human woven bone.
TLDR
Characteristics of apatite crystals in woven bone provide insight into the spatial and temporal relation between collagen and mineral that is the basis for the structure and organization of the mineral comprising human woven bone. Expand
Size and Shape of Mineralites in Young Bovine Bone Measured by Atomic Force Microscopy
TLDR
New AFM data supporting this claim is consistent with findings obtained by electron microscopy and low-angle x-ray and neutron diffraction that mineralites formed within collagen fibrils during initial stages of calcification occur within the hole zone region. Expand
Hydrazine-deproteinated bone mineral
TLDR
Physicochemical data are presented demonstrating that although rat bone crystals more closely resemble synthetic controls made in carbonate-rather than hydroxide-rich media, rat bone apatite cannot be interpreted in terms of known or postulated crystal models in any meaningful fashion. Expand
High-resolution AFM imaging of intact and fractured trabecular bone.
TLDR
Fractured samples, rinsed to remove mineral plates, reveal separated collagen fibrils on the fractured surfaces, providing important insights into the nanostructured architecture of this complex biocomposite. Expand
Aspects of mineral structure in normally calcifying avian tendon.
TLDR
These data provide the first visual evidence supporting the concept that larger plates form from parallel association of smaller ones, and the data fill a gap in knowledge between macromolecular- and anatomic-scale studies of the mineralization of avian tendon and connective tissues in general.
