We sought to further elucidate signal transduction pathways for the I1-imidazoline receptor in PC12 cells by testing involvement of protein kinase C (PKC) isoforms (betaII, epsilon, zeta), and the mitogen-activated protein kinases (MAPK) ERK and JNK. Stimulation of I1-imidazoline receptor with moxonidine increased enzymatic activity of the classical betaII(More)
Mitochondria mediate dual metabolic and Ca(2+) shuttling activities. While the former is required for Ca(2+) signalling linked to insulin secretion, the role of the latter in β cell function has not been well understood, primarily because the molecular identity of the mitochondrial Ca(2+) transporters were elusive and the selectivity of their inhibitors was(More)
Prostate Zn(2+) concentrations are among the highest in the body, and a marked decrease in the level of this ion is observed in prostate cancer. Extracellular Zn(2+) is known to regulate cell survival and proliferation in numerous tissues. In spite of this, a signaling role for extracellular Zn(2+) in prostate cancer has not been established. In the present(More)
BACKGROUND In several case-control and prospective studies, tubal ligation has been associated with a decreased risk of invasive epithelial ovarian cancer. We aimed to assess the potential of tubal ligation in reducing the risk of ovarian cancer in women who carry predisposing mutations in the BRCA1 or BRCA2 genes. METHODS We did a matched case-control(More)
The current research investigates the interaction between thought suppression and individuals' explicit awareness of their thoughts. Participants in three experiments attempted to suppress thoughts of a prior romantic relationship and their success at doing so was measured using a combination of self-catching and experience-sampling. In addition to thoughts(More)
Recent reports demonstrated that neovasculature of certain murine tumours inhibits migration of lymphocytes to malignant tissues. We examined the possible existence of this phenomenon in human prostate adenocarcinoma by relating extent, patterns and composition of leucocyte infiltrates in adenocarcinoma specimens (N=28) to microvessel density and(More)

Overview Research in automated deduction arose in the 1950's and 1960's with the development of high speed electronic computers. It explores methods of knowledge representation and logical deduction that can be efficiently implemented on computers. In this respect, the field is similar to programming languages research, where high-level programming(More)
