Minable rock phosphate is a finite resource. Replacing mineral phosphorus (P) fertilizer with P-rich secondary resources is one way to manage P more efficiently, but the importance of physicochemical and microbial soil processes induced by secondary resources for plant P uptake is still poorly understood. Using radioactive-labeling techniques, the fertilization effects of dairy manure, fish slu...

Introduction P-15 a fifteen residue synthetic peptide (GTPGPQGIAGQRGVV), is a structural analogue of the cell binding domain of Type 1 collagen [1]. P-15 adsorbed on anorganic bovine mineral (ABM-P15) scaffolds has been shown to enhance bone marrow stromal cell growth [2]. This study aimed to investigate the osteogenic potential of human dental pulp stromal cells (HDPSCs) in monolayer culture c...

Tibia segmental defect healing in sheep were clinically, radiographically and histologically evaluated. Twelve young sheep aged four to five months were divided into two groups, G1 and G2. A 3.5 cm long segmental defect was created in the right tibial diaphysis with maintenance of the periosteum. The bone defects in both groups were stabilized with a bone plate combined with a titanium cage. In...

Aim: The study aimed to evaluate the clinical outcomes of bone augmentation with a mixture cortico-cancellous allograft and xenograft collagen membrane in horizontal knife-edge alveolar crests.
 Material Method: Patients ridge thickness less than 4 mm by preoperative tomography were included study. Twelve patients (10 Female, 2 Male) treated Cortico-Cancellous Allograft Bovine Bone Mineral...

Inorganic-organic hybrid materials designed to facilitate bone tissue regeneration use a calcium phosphate mineral layer to encourage cell adhesion, proliferation, and osteogenic differentiation. Mineral formed on porous materials is often discontinuous through the thickness of the scaffold. This study aimed to uniformly coat the pores of three-dimensional (3D) porous, polymer scaffolds with a ...

Hydroxyapatite is chemically related to the inorganic component of bone matrix as a complex structure with the formula of Ca10(OH)2(PO4)6. Previous studies have reported the application of microsized hydroxyapatite to bone regeneration, but the result is not satisfied. The limitation comes from the size of hydroxyapatite. In addition, the duration of treatment is very long. The advantages of hy...

BACKGROUND Hoof lesions in sows have been associated with lameness and poor hoof horn quality. The mechanical strength and quality of hoof horn is determined by the density and diameter of horn tubules, which were recently associated with the severity of lesions on the hoof wall of sows. Histologic changes that have previously been described in cases of bovine laminitis, have also been observed...

The aim of this study was to evaluate the effect of platelet rich plasma (PRP) associated to bovine inorganic bone (Bio-Oss(®); Geistlich) or bioactive glass (Bio-Gran(®); Orthovita, Implant Innovations) on bone healing. Bone cavities were prepared in both sides of the mandible of 4 adult male dogs. The cavities were divided into 4 groups according to the filling material as follows: control, P...

osteoporosis is a major health problem because of the large health care costs associated with its clinical consequences. it is therefore of great importance to identify modifiable risk factors. we investigated association between fruit and vegetables intake and bone mineral density in rural population of tehran surroundings. subjects were a subgroup of a large study on prevalence and causes of ...
