diopside  has  been  successfully  prepared  by  a  modified  sol-gel method.optimization  in calcination temperature and mechanical ball milling  resulted  in  a  pure  and  nano-sized  powder  which characterized by means of scanning electron microscopy (sem), x-ray diffraction (xrd), transmission electron microscopy (tem) and fourier  transform  infrared  spectroscopy  (ft–ir). we  hypothesi...

background : in recent years tissue engineering developed to replace or repair damaged tissues using cell and biomaterial. one of the most important fields of tissue engineering is simulation of in vivo micro environment of body tissues. this study aimed to develop culture chamber and cell biomaterial sheet engineering for the reconstruction of cartilage tissue. methods : stainless steel cultur...

A biomaterial derived from porcine intestinal submucosa has been used in the development of a new biologic wound matrix. This review describes the origin of the wound matrix device, including the discovery of the biomaterial and its properties, to the development of the commercial product currently in clinical use. The composition and structure of this biomaterial are described and considered a...

The purpose of the present study was to formulate and evaluate donepezil loaded bio-nanoparticles for effective treatment of Alzheimer’s disease. For the preparation of bio-nanoparticles biomaterial was isolated from fruits of Carica papaya by an economic method. The biomaterial recovered from the concentrate was subjected for various physicochemical properties like color, solubility, ...

The formation and physico-chemical properties of biomaterial, based on double-stranded (ds) DNA molecules and bearing high concentration of gadolinium, is described. This “rigid” biomaterial demonstrate a few unique properties: 1) the ds DNA molecules forming complexes with gadolinium are fixed in the spatial structure of “rigid” particles, 2) an abnormal negative band in the circular dichroism...
