The authors examined group differences in memories for hearing the news of and reactions to the September 11 attacks in 2001. They measured memory for reception context (immediate memory for the circumstances in which people first heard the news) and 11 predictors of the consistency of memory for reception context over time (flashbulb memory). Shortly after 9/11, a questionnaire was distributed...
PURPOSE Copper chelation reduces the secretion of many angiogenic factors and reduces tumor growth and microvascular density in animal models. ATN-224 is a second-generation analogue of ammonium tetrathiomolybdate. The aim of our phase I study was to reduce serum copper levels, as measured by ceruloplasmin, to 5 to 15 mg/dL (normal 16-60) in 14 to 21 days, to determine the pharmacokinetic profi...
In vitro screening of thiacetazone derivatives indicated that two derivatives, SRI-286 and SRI-224, inhibited a panel of 25 Mycobacterium avium complex (MAC) isolates at concentrations of 2 micro g/ml or lower. In mice, SRI-224 and thiacetazone had no significant activity against the MAC in livers and spleens, but treatment with SRI-286 resulted in significant reduction of bacterial loads in li...
MicroRNAs (miRNAs) have been improved to regulate oocyte development in a cell- or stage-specific manner. In this study, we aimed to clarify microRNA-224's (miR-224) role in cumulus cells (CCs), to find out whether a change level of miR-224 in CCs could influence the maturation of oocyte. We found that overexpression of miR-224 of CCs led to the impairment of cell expansion, along with a decrea...
AIMS This study was designed to identify novel microRNAs (miRNAs) in plasma for detecting and monitoring hepatocellular carcinoma (HCC), independent of hepatic function and background liver diseases with different etiologies. RESULTS (1) Four oncogenic miRNAs (miR-151, 155, 191 and 224) with high expression in HCC tissues were selected as candidates. (2) Quantitative RT-PCR using plasma sampl...
L’espace extra-atmosphérique n’a pas attendu le conflit en Ukraine pour être inclus dans champ de bataille. Ainsi, les mois qui suivent 24 février 2022, deux coalitions spatiales, mêlant moyens publics et privés, se font peu à face, faisant ce milieu contesté un potentiel théâtre d’affrontements.
Abstract The “powder sandwich” method was adapted to the measuring equipment at Laboratory of Radiometric Expertise, IFJ PAN (Kraków, Poland). versatility has been confirmed. values thoron emanation coefficients (f) for 16 materials have determined. It found that value coefficient is not directly dependent on concentration 224 Ra, other factors are also important, e.g. size grains, inter-grain ...
MicroRNAs (miRs) play a key role in the control of gene expression in a wide array of tissue systems, where their functions include the regulation of self-renewal, cellular differentiation, proliferation and apoptosis. However, the function and mechanisms of individual miRs in regulating spermatogonial stem cell (SSC) homeostasis remain unclear. In the present study, we report for the first tim...
