Abstract This research introduced a new poly-ether-ether-ketone calcium hydroxyapatite (PEEK-cHAp) composite for convenient, fast, and inexpensive femur bone-implant scaffold with different lattice structures to mimic natural bone structure. Fused deposition modelling (FDM) was used print hybrid PEEK-based filament-bearing bioactive material suited developing cHAp. Using FDM, the same PEEK will...
The development of three-dimensional (3D) microenvironments that mimic the role native extracellular matrix (ECM) components is very crucial. Self-assembling peptide (SAP) hydrogels have been utilized as scaffolds for encapsulation, 3D culture, proliferation, and differentiation cells also repairing defects in cartilage tissue. SAPs can be biofunctionalized with short epitopes to form biomimeti...
in the present study, anti-anaphylactic, anti-inflammatory and membrane stabilizing properties of a lupine alkaloid plumerianine (compound 1), isolated from the root bark of plumeria acutifolia poir were investigated in animal models. the anti-anaphylactic activity of compound 1 (10, 25 and 50 mg/kg) was studied by using models such as passive cutaneous anaphylaxis, passive paw anaphylaxis and ...
bioactive glasses are silicate-based and can form a strong chemical bond with the tissues. these biomaterials are highly biocompatible and can form a hydroxyapatite layer when implanted in the body or soaked in the simulated body fluid. due to several disadvantages, conventional glass processing method including melting of glass components, is replaced by sol-gel method with a large number of b...
Books and topics of traditional arts (especially hand-made carpet) have not been compiled based on scientific methods. For years, the literature of carpet design and motif is strangely non-structural and full of deficiencies; even the major writers of the field follow in others’ footsteps. This article tries to prepare the ground for a different viewpoint: a better understanding and class...
Ilkhanid, after Iran occupation, achieved Seljuq art and done some changes on it that improved Iran Islamic Art. One of the arts that considerate a lot in architecture was Stucco decoration. These stucco decoration are not identified as well as they are. Approximately the whole stucco are identified by archaeologists, they describe about relation between stucco place and architecture and the ti...
p. atlantica subsp. kurdica, with the local name of baneh, is a wild medicinal plant which grows in kurdistan, iran. the identification of resistance gene analogs holds great promise for the development of resistant cultivars. a pcr approach with degenerate primers designed according to conserved nbs-lrr (nucleotide binding site-leucine rich repeat) regions of known disease-resistance (r) gene...
تهیه، مشخصهیابی و ارزیابی مقایسهای زیست فعالی سه نوع نانو پودر شیشه زیست فعال برای کاربردهای پزشکی
Fabrication of biomaterials with ability to form a bond with bone tissue for bone skeletal system repair is one of the biomaterial science aims. Bioactive glasses containing CaO-SiO2-P2O5 are among the most important groups used in biomedicine and dentistry such as bone defect repair and maxillo-facial reconstruction. The aim of this work was preparation and characterization of nano particle b...
Ceramide is an important lipid signaling molecule and a key intermediate in sphingolipid biosynthesis. Recent studies have implied a previously unappreciated role for the ceramide N-acyl chain length, inasmuch as ceramides containing specific fatty acids appear to play defined roles in cell physiology. The discovery of a family of mammalian ceramide synthases (CerS), each of which utilizes a re...
