This paper is concerned with the development of a piezoelectric d15 shear-induced torsion actuator made of a lead-free piezoceramic material exhibiting giant piezoelectric shear stress coefficient (e15) and piezoelectric transverse shear actuation force comparable to that of lead-based shear-mode piezoceramics. The Mn-modified 0.93(Na0.5Bi0.5TiO3)-0.07BaTiO3 (NBT-BT-Mn) composition exhibited ex...

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.

Cerebral superoxide anion generation during bicuculline-induced seizures was measured in newborn pigs. Using two closed cranial windows inserted over the parietal cortices, superoxide dismutase (SOD)-inhibitable nitroblue tetrazolium (NBT) reduction was determined during 20 min of seizure activity induced by bicuculline, 5 mg/kg i.v. A modest increase in SOD-inhibitable NBT reduction was observ...

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.

dear editor,   the o 2 -generating enzyme nadph oxidase, plays a crucial role in host defense against microbial infection through the production of reactive oxygen species (ros). 1 the multisubunit nadph oxidase complex can be detected in vitro by the nitroblue tetrazolium test (nbt). 2 the nbt test is used for the diagnosis of chronic granulomatous disease. 3 however, several factors, such as ...

This study determined whether nociceptin/orphanin FQ (NOC/oFQ) generates superoxide anion (O(2)(-)) in a protein kinase C (PKC)-dependent manner and whether such production contributes to hypoxic-ischemic (H-I) impairment of N-methyl-D-aspartate (NMDA)-induced pial artery dilation in newborn pigs equipped with closed cranial windows. Superoxide dismutase (SOD)-inhibitable nitroblue tetrazolium ...

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 ...
