The TiO 2 polymorph has a dramatic impact on the electrical conductivity and conduction mechanisms of nominally stoichiometric NBT ceramics prepared by solid-state reaction.

Abstract The effect of electrical poling on the room temperature structural, dielectric and photoluminescence properties small concentration (i.e. 0.5 mole%) Ho +3 substituted sodium bismuth titanate ferroelectric material (Na Bi 0.495 0.005 TiO 3 abbreviated as NBT-0.5Ho) has been investigated. Its crystal structure was found to be mixture two phases rhombohedral (R3c) monoclinic (Cc) in which...

Summary. Aim. The determination of the impact developed complex treatment patients with peritonitis on functional state effector cells antimicrobial resistance during course disease.
 Materials and methods. study included toxic terminal stages (124 patients), who were treated in 2022. They divided into 3 groups. Group I (main) 39 (31.4 %) whose cytochrome C. II 41 (33.1 C Tivorel. comparis...

The present study evaluated the assay to quantify the respiratory burst activity of blood leukocytes of pacu as an indicator of the innate immune system, using the reduction of nitroblue tetrazolium (NBT) to formazan as a measure of the production of reactive oxygen species (ROS). In order to assess the accuracy of the assay, fish were challenged by Aeromonas hydrophila and sampled one week aft...

BACKGROUND This study investigated whether myocardial protection by inhibition of Na(+)/H(+) exchange (NHE) occurs during ischemia and/or during reperfusion. METHODS AND RESULTS The left anterior descending coronary artery was occluded in 32 pigs for 60 minutes and then reperfused for 24 hours. Infarct sizes (nitroblue tetrazolium [NBT] stain, histology) were determined at the end of the expe...

Cell dissociation and cell migration are the two main components of epithelium-mesenchyme transitions (EMT). We previously demonstrated that Ras is required for the accomplishment of both of these processes during the EGF-induced EMT of the NBT-II rat carcinoma cell line in vitro. In this study, we examined the downstream targets of Ras that are responsible for the dissociation and motility of ...

Promyelocytic NB4 leukemia cells undergo differentiation to granulocytes following retinoic acid treatment. Here we report that tissue transglutaminase (TG2), a protein cross-linking enzyme, was induced, then partially translocated into the nucleus, and became strongly associated with the chromatin during the differentiation process. The transglutaminase-catalyzed cross-link content of both the...

Epithelial-mesenchymal transition (EMT) is an essential morphogenetic process during embryonic development. It can be induced in vitro by hepatocyte growth factor/scatter factor (HGF/SF), or by FGF-1 in our NBT-II cell model for EMT. We tested for a central role in EMT of a zinc-finger protein called Slug. Slug mRNA and protein levels were increased transiently in FGF-1-treated NBT-II cells. Tr...

Abstract Background Different trials showed that patients treated with blood transfusion (BT) have unfavorable prognosis regarding outcomes and mortality. Nevertheless, in BT hospitalized a contemporary tertiary intensive cardiac care unit (ICCU) is limited. Objective To determine mortality rate ICCU. Methods A prospective single center study to evaluate short- long-term of between January 2020...
