Many studies have shown that microRNA expression in cancer may be regulated by epigenetic events. Recently, we found that in lung cancer miR-212 was strongly down-regulated. However, mechanisms involved in the regulation of miR-212 expression are unknown. Therefore, we addressed this point by investigating the molecular mechanisms of miR-212 silencing in lung cancer. We identified histone modif...

PURPOSE Recent studies from this laboratory with (212)Pb-trastuzumab have shown the feasibility of targeted therapy for the treatment of disseminated peritoneal disease using (212)Pb as an in vivo generator of (212)Bi. The objective of the studies presented here was improvement of the efficacy of alpha-particle radioimmunotherapy using a chemotherapeutic agent. EXPERIMENTAL DESIGN In a series...

Trigger capability for dimuon events is discussed. The acceptance and low momentum reach are calculated. The rates of muon trigger caused by prompt muons, hadron decays and hadronic punchthrough are examined. A trigger strategy for Pb-Pb collision is proposed to ensure high efficiency for the signal and acceptable background rates. Possible modifications for lighter ions are briefly discussed. ...

The most abundant components of primitive meteorites (chondrites) are millimeter-sized glassy spherical chondrules formed by transient melting events in the solar protoplanetary disk. Using Pb-Pb dates of 22 individual chondrules, we show that primary production of chondrules in the early solar system was restricted to the first million years after the formation of the Sun and that these existi...

This study was aimed at assessing prevalence, circumstance, and management of acute pesticide poisoning in hospitals in Kampala. It was a retrospective cross-sectional study that involved reviewing of 739 poisoning patient records from 5 hospitals in Kampala. Of the 739 patients, 212 were due to pesticide poisoning resulting in a prevalence of 28.8%. About 91.4% (191/210) of the cases were due ...

MK-212 (1 x 10(-7)M -- 1 x 10(-5)M) produced dose-dependent contractions of guinea pig ileum, taenia coil and rat fundus strip. The responses to MK-212 in all three preparations were blocked competitively by cyproheptadine (1 x 10(-8)M) a 5-HT receptor antagonist. Mepyramine (1 x 10(-8)M)-H1 receptor antagonist also inhibited competitively the responses of guinea pig ileum and taenia coli to MK...

Non-alcoholic fatty liver disease (NAFLD) is associated with obesity and lifestyle, while exercise is beneficial for NAFLD. Dysregulated microRNAs (miRs) control the pathogenesis of NAFLD. However, whether exercise could prevent NAFLD via targeting microRNA is unknown. In this study, normal or high-fat diet (HF) mice were either subjected to a 16-week running program or kept sedentary. Exercise...
