Since there have been no published molecular studies of Pneumocystis jirovecii isolates from Iranian patients, we investigated the genotypes of such isolates recovered from HIV-infected patients, those undergoing cancer chemotherapy and patients with chronic obstructive pulmonary disease (COPD). P. jirovecii typing, based on ITS1 and ITS2 sequence analysis, was performed on 34 isolates from Ira...

One of the major mechanisms involved in acetaminophen (APAP)induced hepatotoxicity is hepatocyte nuclear factor 4a (HNF4a)mediated activation of pregnane X receptor (PXR) and constitutive androstane receptor (CAR). In the present study, we investigated the role of miR-561 and its target gene DAX-1 encoding a corepressor of HNF4a in the process of APAP-induced hepatotoxicity. We used both human ...

FRAMEWORK AND ANALYSIS Most randomized incremental algorithms in the literature follow the framework sketched here for the computation of the trapezoidal map: the structure to be computed is maintained while the objects defining it are inserted in random order. To insert a new object, one first has to find a “conflict” of that object (the location step), then local updates in the structure are ...
