Hepatitis C viral infection occurs relatively low in Korea compared to hepatitis B. However, it progresses into chronic hepatitis and cirrhosis more frequently than HBV. It may be associated with cryoglobulinemia and glomerulonephritis, both in native and transplanted kidneys. We report three cases of membrano-proliferative glomerulonephritis type I in anti-HCV positive, but cryoglobulin-negati...

Amyloidosis is a disease characterized by the formation of extracellular amyloid deposits. Immunoglobulin light-chain amyloidosis can appear as a local disorder presenting with mild symptoms or as a life threatening systemic disease. The systemic form of immunoglobulin light-chain amyloidosis is the most common type of amyloidosis in western countries although it is a rare disease. Identificati...

The identification of geological and industrial types mineral deposits has an important theoretical applied significance for their prospecting, resource evaluation development. This problem transformed into independent branch science. It is shown by the example titanmagnetite-ilmenite type in stratified intrusions, where main useful elements are triad Fe, Ti V. geochemical, mineralogical, miner...

PURPOSE Sub-RPE deposits form in a variety of conditions most notably in age-related macular degeneration. The purpose of this study was to generate sub-RPE deposits in vitro and to test the hypotheses that high protein concentrations or retinal homogenate increase deposit formation and that a challenge with tumor necrosis factor (TNF)-alpha or metalloproteinase (MMP)-2 decreases such deposits....

The hand stencils of European Paleolithic art tend to be considered of pre-Magdalenian age and scholars have generally assigned them to the Gravettian period. At El Castillo Cave, application of U-series dating to calcite accretions has established a minimum age of 37,290 years for underlying red hand stencils, implying execution in the earlier part of the Aurignacian if not beforehand. Togethe...

Fracture models of vein formation can produce realistic training images (TIs) for use in multiple-point geostatistics. Vein formation is modeled by applying flow simulation to a fracture model to mimic the flow of an ore-bearing fluid through fractured rock. TIs are generated by assuming that veins form in areas of high flow where there would be preferential deposition of the mineral of interes...

Membranous lupus nephritis (MLN) and idiopathic membranous nephropathy (IMN) are kidney diseases with similar morphology, but distinct etiologies, both producing glomeruli with immune deposits. Immunoglobulins and complements, the main components of the deposits, can be detected by immunofluorescence (IF) microscopy. Previous researches characterized the immune deposits only individually, but n...

Isotopic composition of uranium has previously been used to infer the depositional redox environment ore concentrates and also provide a potential signature inform nuclear forensic investigations. This study evaluates diagnostic power U isotope by investigating (1) heterogeneity compositions in samples collected from same mine and/or vein, (2) influence processing on 238U/235U 234U/238U ratios....
