The type I collagen was studied in samples of two types osteoplastic materials produced the Biotech Research Institute Samara State Medical University using immunoblotting. demineralized used work were compact bone powder and crushed material human cancellous tissue. Collagen its polypeptides separated a 5% polyacrylamide gel with 3.6 M urea according to method Hayashi Nagai (1979). advantage i...

Collagen model peptides (CMPs) consisting of proline-(2S,4R)-hydroxyproline-glycine (POG) repeats have provided a breadth knowledge the triple helical structure collagen, most abundant protein in mammals. Predictive tools for helix stability have, however, lagged behind since effect CMPs with different frames ([POG]n, [OGP]n, or [GPO]n) and capped uncapped termini so far been underestimated. He...

Objective- The aim of this study was to evaluate possible beneficial effect of tricalcium phosphate/collagen (TCP/collagene) nanocomposite scaffold on bone healing in rabbits using biochemical assessmentsDesign- Experimental studyAnimals- Twelve healthy male white New Zealand rabbitsProcedures- The rabbits wer...

Objectives: To evaluate the physico-chemical and functional characteristics of stinging catfish muscle tissue during storage time 18 hours following death fish. Methods: In present study, were collected from paddy fields streams near Tiruvalla Kerala. Fish slaughtered immediately analyzed for changes in pH value, cook loss, expressible water content, holding capacity, sensory demerit score valu...

background: nanosized ceramics may represent a promising class of bone graft substitutes due to their improved osseointegrative properties. nanocrystalline hydroxyapatite (ncha) bind to bone and stimulate bone healing by stimulation of osteoblast activity. the present study aims to explore the clinical and radiographical outcome of ncha bonegraft (sybograf®) with collagen membrane (periocol®), ...

objective: spermatogonial stem cells (sscs) are the only cell type that can restore fertility to an infertile recipient following transplantation. much effort has been made to develop a protocol for differentiating isolated sscs in vitro. recently, three-dimensional (3d) culture system has been introduced as an appropriate microenvironment for clonal expansion and differentiation of sscs. this ...
