spinal cord injury (sci) in humans remains a devastating and incurable disorder. a very important obstacle in axonal regeneration after spinal cord injury is astroglial scaring. the use of self-assembling peptide nanofiber, a hydrogel mimicking extracellular matrix, has been suggested as a scaffold for spinal cord regeneration and inhibition of astrogliosis. however, neurogenesis potential of l...
background: spermatogonial stem cells are subpopulation of spermatogonial cells in testis tissue that support beginning and maintenance of spermatogenesis. ubiquitin carboxy-terminal hydrolase l1 (uchl1) could be a specific marker for identification of spermatogonial stem cells including spermatogonial sperm cells (sscs) in testis tissue and during the culture; therefore we undertook this study...
Laminin-2 promotes basement membrane assembly and peripheral myelinogenesis; however, a receptor-binding motif within laminin-2 and the downstream signaling pathways for motif-mediated cell adhesion have not been fully established. The human laminin-2 alpha2 chain cDNAs cloned from human keratinocytes and fibroblasts correspond to the laminin alpha2 chain variant sequence from the human brain. ...
Lu/BCAM (Lutheran/basal cell-adhesion molecule) is a laminin 511/521 receptor expressed in erythroid and endothelial cells, and in epithelial tissues. The RK573-574 (Arg573-Lys574) motif of the Lu/BCAM cytoplasmic domain interacts with αI-spectrin, the main component of the membrane skeleton in red blood cells. In the present paper we report that Lu/BCAM binds to the non-erythroid αII-spectrin ...
abstract the purpose of this study is twofold: on the one hand, it is intended to see what kind of noticing-the –gap activity (teacher generated vs. learner generated) is more efficient in teaching l2 grammar in classroom language learning. on the other hand, it is an attempt to determine which approach of the noticing-the-gap- activity is more effective in the long- term retention of grammar...
Mutations in the laminin-332 (α3Aβ3γ2) genes cause junctional epidermolysis bullosa (JEB), a recessively inherited disease characterized by blistering and altered wound repair. In addition, specific mutations that affect the N-terminus of the α3A chain cause a JEB-related non-blistering condition characterized by chronic production of granulation tissue, suggesting a critical role of this regio...

abstract this study aimed at investigating the impact of etymology strategy instruction on the development of vocabulary of iranian intermediate efl learners. etymology, knowledge of origin of words, roots, and affixes, has proved to be a controversial issue and a question of long debate with regard to its impact on the process of vocabulary learning. this study employed etymology strategy in ...
ساخت یک نانوزیست حسگر بر پایه i-motif (ساختار چهار رشته ای غنی از سیتوزین) و بررسی برهمکنش آن با تعدادی از ترکیبات ضدسرطان زعفران بود. برای ساخت این نانوزیست حسگر ابتدا سطح الکترود با ترکیبات نانولوله های کربنی اصلاح شد اصلاح سطح الکترود بستر مناسبی را برای تثبیت i-motif فراهم می کند. در این راستا i-motif در حضور nhs edc/ بر روی سطح الکترود اصلاح شده با نانولوله های کربنی از طریق واکنش بین عامل...
