Na1/2Bi1/2TiO3-based relaxor ferroelectrics are extensively investigated for use in transduction applications because of their relatively large electromechanical properties. Integration these materials into devices, however, requires better temperature stability addition to This work demonstrates a novel approach enhance the long-range ferroelectric order as well properties non-ergodic 0.93(Na1...

The local symmetry of (1-x)Na0.5Bi0.5TiO3-xKNbO3 (NBT-xKN, x = 0.01−0.07) ceramics was thoroughly examined using high-energy synchrotron x-ray scattering and analysed the pair distribution function (PDF) method. At room temperature, structure NBT-xKN (x best refined monoclinic C1c1 structures within local-range (r<22 Å) rhombohedral R3c medium-range (22 Å <r <52 Å). Furthermore, exists from tem...

Recombinant intetferon-y (rlFN-y) therapy has become an effective form of prophylaxis for patients with chronic granulomatous disease (CGD). Preliminary studies with CGD suggested that r1FN-y treatment enhanced phagocyte oxidase activity and increased superoxide (O,-) production. We evaluated several aspects of neutrophil NADPH oxidase activity in 19 CGD patients (representing all four known ty...

Two tubeless tests of exocrine pancreatic function, the NBT-PABA test and faecal chymotrypsin (FCT) assay were compared. Thirteen patients with Fibrocalculous Pancreatic Diabetes (FCPD), 12 patients with Insulin Dependent Diabetes Mellitus (IDDM) and 13 control subjects were studied. Using a PABA excretion value < 43%, 100% of FCPD patients and 58.3% of IDDM patients had abnormal exocrine pancr...

PURPOSE To assess the safety and usefulness of neutron brachytherapy (NBT) as an adjuvant in the treatment of patients with gastroesophageal junction adenocarcinoma (GEJAC) with external beam radiation (EBRT), with or without chemotherapy. METHODS AND MATERIALS In total, 197 patients with localized, advanced GEJAC received EBRT and NBT with or without chemotherapy. Radiotherapy consisted of e...

BACKGROUND Pressure ulcer (PU) is common in immobile elderly patients, and there are some research works to investigate a preventive and curative method, but not to find sufficient effectiveness. The aim of this study is to clarify the clinical effectiveness on wound healing in patients with PU by hydrogen-dissolved water (HW) intake via tube-feeding (TF). Furthermore, normal human dermal fibro...

A study of leucocyte response to infection, polymorphonuclear leucocyte chemotaxis and bactericidal activity, and nitroblue tetrazolium (NBT) reduction in children with kwashiorkor was undertaken and compared with a control group. The results show that total leucocyte counts were depressed in children with kwashiorkor, and lymphopenia was not infrequent. NBT reduction was normal. Abnormal polym...

The nitroblue tétrazolium (N B T ) test is most useful for the diagnosis of chronic granulomatous disease and a few other rare metabolic abnormalities of neutrophils. It may be helpful in suggesting the presence of infection when values of both percentage of N BT positive neutrophils and total number of N BT positive neutrophils are markedly increased. Each patient must be inter­ preted with ca...

This paper deals with an in-depth analysis on the role of microstructure phase titanium dioxide (TiO2) precursor in sodium bismuth titanate (Na0.5Bi0.5TiO3, hereafter represented as NBT) ceramics prepared through hydrothermal method. The comparison grain size, microstructure, crystal structure, and electrical properties NBT is carried out using anatase rutile TiO2. TiO2 (denoted by NBTA) displa...

Major bacterial infections are most commonly associated with agranulocytosis or an abnormality of immunoglobulins or complement. Occasionally, repeated infections cannot be attributed to these relatively common causes. In such cases, a quantitative abnormality in neutrophil function should be sought. Complete evaluation of neutrophil function, including: chemotaxis, adhesion, aggregation, phago...
