Membranoproliferative glomerulonephritis (MPGN) type 2 is characterized by electron-dense deposits in the glomerular basement membrane and drusen-like deposits in Bruch's membrane. Over time, atrophic changes in the retina and retinal pigment epithelium occur, which can progress to choroidal neovascularization (CNV). This report describes a patient with MPGN type 2 who developed progressive los...

Abstract The western North American Great Basin's Carlin-type deposits represent the largest accumulation of gold in Northern Hemisphere. controversy over their origins echoes debate between Neptunists and Plutonists at birth modern geology: were causative processes meteoric or magmatic? Sulfur isotopes have long been considered key to decoding metal cycling Earth's crust, but previous studies ...

Post-mineralization activities may cause difficulties in the process of ore modeling in porphyry deposits. Sungun, NW Iran, is one of the porphyry copper deposits, in which dyke intrusions have made ore modeling more complicated than expected. Among different kinds of dykes, two types were chosen and the consequent geostatistical analyses were applied on. In this study, simple directional vario...

Introduction . The study of the conditions for development discontinuous disturbances makes it possible to draw conclusions that in formation and destruction various deposits, they are connected by discontinuities different mechanism their formation. lithological composition rocks contact with has a certain significance assessing these gaps relation or disbandment deposits. main role here is pl...

In 1965, it was observed that patients with glomerulonephritis with persistently low serum concentrations of C3 evolved to have similar glomerular morphologic characteristics, particularly recognizable in biopsy specimens stained by the Jones methenamine silver technique [1]. Subsequent observations have indicated that although long-standing hypocomplementemia is commonly observed and is unique...
