Here, we describe the mechanisms underlying the regulation of mitochondrial functions during apoptosis by TRAP1.”
“Lymphomatoid granulomatosis (LYG) of the lung is an extremely rare, Epstain-Barr virus-related lymphoproliferative
AL3818 mouse disease. We report a case of pulmonary LYG that presented as a large necrotic mass.”
“Human kidneys produce more than 4 million litres of virtually protein-free primary urine in a lifetime. In healthy individuals, the sieving process is accomplished by the glomerular filter without the smallest sign of clogging, even in old age. How nature accomplishes this extraordinary task is a mystery, but unravelling the functioning of the glomerular filter is important. The basic principles that govern glomerular filtration are probably
also true for peripheral filtering by fenestrated capillaries. In addition, understanding the sieving process is a prerequisite to understanding the pathogenesis of proteinuria (that is, the leakage of plasma proteins into the urine). Proteinuria is the hallmark of glomerular disease and a major risk factor for systemic cardiovascular LY2157299 concentration complications, a fact that emphasizes the relationship between the glomerular and peripheral filtering capillaries. In this Review, we briefly summarize the major models that have been proposed for the mechanisms of glomerular filtration and discuss their strengths and limitations. A special emphasis is placed on the ‘electrokinetic model’ that we have proposed, a model that could potentially resolve many of the seemingly strange characteristics of the glomerular filtration barrier.

“The cytochrome P450 (P450, CYP) enzyme superfamily is associated with the metabolism of drugs, environmental pollutants and endogenous substrates with broad overlapping substrate specificities. In addition, species differences between experimental animals and humans in the roles of P450 enzymes in drug metabolism are determinant factors in the drug discovery
process. The CX-6258 induction and inhibition of P450-dependent metabolism, especially in the case of P450 3A enzyems, can cause serious problems in clinical practice and in the attrition of drug candidates because of adverse toxicology or pharmacokinetics. Recently, chimeric mice whose livers have been replaced to a level of 80% or more with human hepatocytes were established using urokinase-type plasminogen activator transgenic/severe combined immunodeficiency (uPA/SCID) mice. In the livers of these chimeric mice, hepatic cords and sinusoid-like structures were observed. Moreover, bile canaliculi associated with human hepatocytes were also detected. The mRNA expressions derived from humans of 52 phase I and 26 phase II enzymes (including 20 P450s) and 21 transporters were ascertained in the chimeric mice liver.
