STAT4, which plays a pivotal role in Th1 immune responses, enhances IFN-gamma transcription in response to the interaction of IL-12 with the IL-12R. Mice deficient in STAT4 lack IL-12-induced IFN-gamma production and Th1 differentiation and display a predominantly Th2 phenotype. Although these findings indicate that STAT4 expression levels are important for(More)
Early diabetic nephropathy is characterized by glomerular hyperpermeability as a result of impaired glomerular filtration structure caused by hyperglycemia, glycated proteins or irreversible advanced glycosylation endproducts (AGE). To investigate the effect of ginseng total saponin (GTS) on the pathologic changes of podocyte ZO (zonula occludens)-1 protein(More)
To simulate the functionalities of the real cash, one of the important requirements of electronic cash systems is the anonymity of users. Unconditional anonymity, however, is also very well suited to support criminals in blackmailing. Recently Kügler and Vogt [6] proposed a payment system based on the blind undeniable signature that protects the privacy of(More)
Proteinuric conditions demonstrate structural and compositional changes of the foot processes and slit diaphragms between podocytes. p130Cas in podocytes serves as an adapter protein anchoring glomerular basement membrane to actin filaments of podocyte cytoskeleton. To investigate the effect of ginseng total saponin (GTS) on the pathologic changes of(More)
PURPOSE Puromycin aminonucleoside (PAN) specifically injures podocytes, leading to foot process effacement, actin cytoskeleton disorganization, and abnormal distribution of slit diaphragm proteins. p130Cas is a docking protein connecting F-actin fibers to the glomerular basement membrane (GBM) and adapter proteins in glomerular epithelial cells (GEpCs;(More)
BACKGROUND Adenosine monophosphate-activated protein kinases (AMPKs), as a sensor of cellular energy status, have been known to play an important role in the pathophysiology of diabetes and its complications. Because AMPKs are known to be expressed in podocytes, it is possible that podocyte AMPKs could be an important contributing factor in the development(More)
OBJECTIVE This study aims to compare liver function indices (aspartate aminotransferase [AST], alanine aminotransferase [ALT], and gamma glutamyl transferase [GGT]) among males who work with lead, organic solvents, or both lead and organic solvents, under the permissible exposure limit (PEL). METHODS A total of 593 (out of 2,218) male workers who agreed(More)
Angiotensin II (Ang II) induces the pathological process of vascular structures, including renal glomeruli by hemodynamic and nonhemodynamic direct effects. In kidneys, Ang II plays an important role in the development of proteinuria by the modification of podocyte molecules. We have previously found that Ang II suppressed podocyte AMP-activated protein(More)
BACKGROUND The actin cytoskeleton in podocytes is essential for the maintenance of its normal structure and function. Its disruption is a feature of podocyte foot-process effacement and is associated with proteinuria. α-Actinin-4 in podocytes serves as a linker protein binding the actin filaments of the cytoskeleton. METHODS To investigate the effect of(More)
With the rapid growth of ubiquitous computing, it is possible to collect various kinds of information related to the cities from heterogeneous ubiquitous devices like RFID (Radio Frequency Identification) tags, CCTV (closed-circuit television) and sensors. In addition, information from existing legacy systems (e.g. Intelligent Transport System, Urban(More)
