among the low–dimensional allotropes of carbon, nanotubes and graphene have attracted very much attention from nano–science and nanotechnology specialists. they have been proposed as building blocks in nanometer device engineering. however, these structures are not defect–free. in this thesis, we focused on defective carbon nanotubes and graphene, and studied the effect of couple of very common...
The interaction of hepatocytes with the basement membrane glycoprotein laminin was studied using synthetic peptides derived from laminin sequences. Rat hepatocytes bind to laminin and three different sites within the A and B1 chains of laminin were identified. Active laminin peptides include the PA22-2 peptide (close to the carboxyl end of the long arm in the A chain), the RGD-containing peptid...
Degenerate primers-based polymerase chain reaction (PCR) are commonly used for isolation of unidentified gene sequences in related organisms. For designing the degenerate primers, we propose the use of local alignment search method for searching the conserved regions long enough to design an acceptable primer pair. To test this method, a WD40 repeat-containing domain protein from Beauveria bass...
Recent work suggests that the dissemination of tumor cells may occur in parallel with, and even preceed, tumor growth. The mechanism for this early invasion is largely unknown. Here, we find that mammary epithelial cells (MECs) induce neighboring breast carcinoma cells (BCCs) to cross the basement membrane by secreting soluble laminin. Laminin continuously produced by MECs induce long membrane ...
Kerman nomadic hand-woven carpets, woven without a detailed advance plan, is today one of the less discussed issues in the industry. Rafsanjan, Raviz carpet is among hundreds of nomadic carpets with significant authenticity and different motifs, including tree, mecca, flower pot, boteh, brick, medalion. The tree motif is one of the most beautiful features mainly seen in carpets woven in this ar...
The aim of this study was to analyze the expression extracellular matrix (ECM) proteins in human endoneurium during aging. We harvested 15 cadaveric sural nerves, distributed 3 age groups (I: 25-44, II: 45-64, III: 65-86 years old). Histological sections were stained immunohistochemically for presence collagen type I, IV and laminin, ImageJ processing program used morphometrical analysis determ...
The long arm of laminin, which binds heparin and cells, consists of three polypeptides (A, B1, and B2) joined in a coiled-coil rod attached to a terminal A chain globule (G). Previously, we found that recombinant globular domain (rG) supported heparin and myoblast binding (Yurchenco, P. D., U. Sung, M. D. Ward, Y. Yamada, and J. J. O'Rear. 1993. J. Biol. Chem. 268:8356-8365). To further analyze...
in the area of vocabulary teaching and learning although much research has been done, only some of it has led to effective techniques of vocabulary teaching and many language learners still have problem learning vocabulary. the urge behind this study was to investigate three methods of teaching words. the first one was teaching words in context based on a traditional method of teaching that is,...
It can be said that a part of our cultural-artistic identity and even national identity is interwoven with carpet. Persian carpet history has been glorious and brilliant,and the artisans of the field, relying on rich and prolific past and the road which has been taken, can inspire innovation to keep it alive. Thus, one of the tasks of the researchers in this context is introducing the rich past...
Thin and ultrathin cryosections of mouse cornea were labeled with affinity-purified antibodies directed against either laminin, its central segments (domain 1), the end of its long arm (domain 3), the end of one of its short arms (domain 4), nidogen, or low density heparan sulfate proteoglycan. All basement membrane proteins are detected by indirect immunofluorescence exclusively in the epithel...
