As a burnable absorber, gadolinium oxide (Gd2O3) is widely used in light water reactors due to the high neutron absorption cross section of several isotopes and its good solid solubility UO2. However, some natural Gd cause residual reactivity suppression, while are not efficient absorbers, reducing efficiency absorber when implemented. In this study, fuel assemblies utilizing enriched with 157G...

Background. The effects of smoking, alcohol consumption, obesity, and a sedentary lifestyle on endothelial function (EF) have only been examined separately. The relative contributions of these behaviours on EF have therefore not been compared. Purpose. To compare the relative associations between these four risk factors and brachial artery reactivity in the same sample. Methods. 328 patients re...

a b s t r a c tintroduction: craving to methamphetamine is a significant health concern and exposure to methamphetamine cues in laboratory can induce craving. in this study, a task designing procedure for evaluating methamphetamine cue-induced craving in laboratory conditions is examined. methods: first a series of visual cues which could induce craving was identified by 5 discussion sessions b...

The present research describes the synthesis of novel 5-benzoyl-N-substituted-amino- and 5-benzoyl-N-sulfonylamino-4-alkylsulfanyl-2-pyridones 5a-c and 6a-c via the reaction of 2-benzoyl-3,3-bis(alkylthio)acrylonitriles 2a-c with N-cyanoacetohydrazide 3 and cyanoaceto-N-phenylsulfonylhydrazide 4, respectively. Also, the reactivity of the compounds 5a-c toward hydrazine hydrate to give product 1...

Immunohistochemical reactivity with OKT9 (antitransferrin receptor) monoclonal antibody was studied in 58 surgically resected adenocarcinomas of the lung. The cell surface and cytoplasm of the tumor cells were stained in 44 cases (76 percent). The expression of the transferrin receptor (TrfR) in tumor cells was compared with histopathologic prognostic factors, such as TNM factors, degree of his...

We have compared the nuclear reactions of the alkylating agents chlorambucil, melphalan, and cyclophosphamide used alone, with those produced when the same drugs were used in combination with the corticosteroid prednisolone. Studies were performed in vivo in Wistar rats bearing ascites forms of either the Yoshida sarcoma or the Walker carcinosarcoma. Strains of both tumor lines, which were sens...

UNLABELLED THE AIM of our study was to evaluate the prognostic significance of p53 protein immunoreactivity for prostate cancer and to determine whether p53 immunoreactivity correlates with the Gleason tumor grade in primary adenocarcinoma. Prostate fragments were fixed in 10% formalin, paraffin-embedded, sectioned and standard Hematoxylin-Eosin stained, then examined using histological grade (...

PURPOSE To determine whether, by employing recent advances in immunocytochemical technique, it is possible to identify reliably the product of the retinoblastoma (RB) susceptibility gene, p110RB1, in formalin-fixed, paraffin-embedded eyes with commercially available primary antibodies. If so, the authors sought to determine the distribution of p110RB1 in normal human eyes and retinoblastomas in...

The cross-reaction of IgM-rheumatoid factors (IgM-RF) with a cell nuclear antigen has been further investigated by immunofluorescence procedures. This reaction appears to be optimal at pH 8-9, and fails to occur at pH 6.5. No evidence was obtained by immunofluorescence that IgM-RF bound to the cell nuclear antigen fixes complement. It would appear that the nuclear reactivity of IgM-RF may be of...
