The basement rocks encountered in exploratory boreholes drilled for exploration and evaluation of coal deposits in Thar Parkar district, Sindh Pakistan have formed the basis for present studies. The basement complex was penetrated through eighteen boreholes at drill depth range from 112 to 279 meters. These rocks were identified in field as Pink and Grey Granites.. The basement rocks are of Ign...

Basement membranes were separated from rat glomeruli and purified by mild procedures, which led to a highly enriched basement membrane fraction. Here, the production and characterization of five monoclonal antibodies against tubular and glomerular basement membranes are described. These antibodies were analyzed immunohistochemically on frozen sections of rat, bovine, and human kidneys as well a...

Basement membranes (BMs) are thin, dense sheets of specialized, self-assembled extracellular matrix that surround most animal tissues (Figure 1, top). The emergence of BMs coincided with the origin of multicellularity in animals, suggesting that they were essential for the formation of tissues. Their sheet-like structure derives from two independent polymeric networks - one of laminin and one o...

We have isolated a unique, basement membrane proteoglycan from the Engelbreth-Holm-Swarm (EHS) sarcoma. This proteoglycan, estimated to be 0.75 X 10(6) daltons, was found to contain about equal amounts of protein and covalently linked heparan sulfate. Antibody prepared against this proteoglycan reacts with the basement membrane matrix in the tumor and with the basement membranes in skin, kidney...

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...

A parietal yolk sac carcinoma of the mouse that secretes large quantities of basement membrane-like material has been used to study the formation of basement membranes. Suitably characterized fluorescein-labeled antibodies against this material stained basement membranes of epithelial structures and vessels, as well as reticulin. When absorbed with reticulin and vascular basement membranes of t...

objective(s) extracellular matrix (ecm) and basement membrane (bm) play important roles in many developmental processes during development and after birth. among the components of the bm, collagen fibers specially type iv are the most important parts. the aim of this study was to determine the time when collagen type iv appears in the bm of lens structure during mouse embryonic development. mat...

abstract basement membrane of glomerular mesangium (bmg) is a thin membrane which helps to support the capillary loops in a renal glomerulus and type iv collagen is require for complete bm formation during glomerulogenesis. in this investigation specific antibody of type iv collagen has been used in light microscopy to study development of bmg of the embryonic and postnatal mouse glomerular mes...

A geophysical method of investigation has been deployed in order to give a quick overview the nature and rapidly changing subsurface lithologies that characterized Yikpata, Share, Kwara State, Nigeria. total nine (9) vertical electrical soundings (VES), using Schlumberger Array uniformly divided into three groups: basement, basement/sedimentary boundary sedimentary terrain, horizontal profiling...
