We have observed several IR bands of CH3CN-BF3 in neon and nitrogen matrices. For the 11B isotopomer in neon matrices, we observed the BF3 symmetric deformation band (nu7) as a doublet at 600 and 603 cm(-1), the BF3 symmetric stretching band (nu6) as a doublet at 833 and 838 cm(-1), the BF3 asymmetric stretching mode (nu13) at 1281 cm(-1) (partially obscured), and the C-N stretching mode (nu2) ...
BACKGROUND Safety of heparin bridging therapy for transrectal ultrasound-guided prostate (TRUS) biopsy in patients requiring temporary discontinuation of antithrombotic therapy is unknown. This study aimed to assess the relationship between heparin bridging therapy and the incidence of complications after TRUS biopsy. METHODS From January 2005 to November 2015, we performed 1307 consecutive T...
The (2;5)(p23;q35) translocation which results in the fusion of the NPM (nucleophosmin) gene on chromosome 5q35 with the novel ALK (anaplastic lymphoma kinase) gene on chromosome 2p23 [S.W. Morris et al., Science (Washington DC), 263: 1281-1284, 1994] is associated with Ki-1 (CD30)-positive anaplastic large cell lymphomas (ALCL); a group of morphologically and immunophenotypically heterogenous ...

OBJECTIVES We examined the effectiveness of risk reduction counseling and the role of on-site HIV testing in drug treatment. METHODS Between January and May 2009, we randomized 1281 HIV-negative (or status unknown) adults who reported no past-year HIV testing to (1) referral for off-site HIV testing, (2) HIV risk-reduction counseling with on-site rapid HIV testing, or (3) verbal information a...
Calcium transients are known to control several transition points in the eukaryotic cell cycle. For example, we have previously shown that a coordinate elevation in the intracellular free calcium ion concentration is required for G1to S-phase cell cycle progression in vascular smooth muscle cells (VSMC). However, the molecular basis for this Ca sensitivity was not known. Using buffers with diff...
The anti-diabetic drug metformin is endowed with anti-cancer properties. Epidemiological and experimental studies, however, did not provide univocal results regarding its role in pulmonary carcinogenesis. We used Swiss H mice of both genders in order to detect early molecular alterations and tumors induced by mainstream cigarette smoke. Based on a subchronic toxicity study, oral metformin was u...
Separate pathways have recently been proposed for ‘‘fast’’ and ‘‘slow’’ motion, whose properties differ in the way that color contrast is processed [see Nature (London) 367, 268 (1994); Trends Neurosci. 19, 394 (1966); and Vision Res. 36, 1281 (1996) and 35, 1547 (1995)]. One reported difference is that for slow motion the direction of chromatic stimuli cannot be determined at detection thresho...
We review the class of partial-propensity exact stochastic simulation algorithms (SSA) for chemical reaction networks. We show which modules partial-propensity SSAs are composed of and how partial-propensity variants of known SSAs can be constructed by adjusting the sampling strategy used. We demonstrate this on the example of two instances, namely the partial-propensity variant of Gillespie’s ...
The DMA content of murine fibrosarcoma cell lines of various metastatic potential was the subject of the current investigation. The cell lines were derived from methylcholanthrene-induced tumors as described previously (J. Varani ef al., J. Nati. Cancer Inst., 71: 1281-1287,1983). Cells were maintained in vitro and used for DNA studies no more than 48 h after passage. DNA staining was accomplis...
