Structure and function of basement membrane.
Progress has been made in identifying and characterizing basement membrane macromolecules, including type IV collagen, laminin, a heparan sulfate proteoglycan and bullous pemphigoid antigen. Basement membrane contains a unique collagen, type IV collagen, which is formed of pro alpha 1(IV) (Mr = 185,000) and pro alpha 2(IV) (Mr = 170,000) chains. As opposed to the fibrillar pattern seen with oth...
متن کامل[Structure and function of glomerular basement membrane].
The glomerular basement membrane (GBM) is thin extracellular matrices which separate the visceral epithelium of the glomerulus from the capillary endothelium and serves as a filter for blood molecules. GBMs are composed of type IV collagen, laminin, heparan sulfate proteoglycan, entactin/nidogen, fibronectin and other minor glycoproteins which are not characterized. Recent technological advance...

هدف از انجام این تخقیق بررسی رابطه احتمالی بین سطح مهارت زبان خارجی (foreign language proficiency) و ساختار مهارت زبان خارجی بود. تعداد 314 زبان آموز مونث و مذکر که عمدتا دانشجویان رشته های زبان انگلیسی در سطوح کارشناسی و کارشناسی ارشد بودند در این تحقیق شرکت کردند. از لحاظ سطح مهارت زبان خارجی شرکت کنندگان بسیار با هم متفاوت بودند، (75 نفر سطح پیشرفته، 113 نفر سطح متوسط، 126 سطح مقدماتی). کلا ...

An understanding of the biochemical basis of membrane function is an important goal of present day biology. In this paper, a biochemical approach to the problem of the specific transport of sugars across the membrane of Escherichia coli is discussed. A new biochemical model for lactose transport system in this organism is presented, in which a specific membrane protein (M protein) plays the rol...
متن کاملBasement membrane.
Basement membrane has attracted less attention than the other components of connective tissue. But, like the other extracellular fibres and matrix materials, it can profoundly influence both the structure and function of advanced life forms. Usually taking the shape of thin, structureless cementing material between epithelial and connective tissue, basement membranes are widely distributed thro...
