Quenching has been established as a viable method to increase the depolarization temperature in (100-x) Na1/2Bi1/2TiO3–xBaTiO3 (NBT–xBT). The proposed hypothesis of stabilized ferroelectric order would entail changes polarized volume. To this end, air-quenched and furnace cooled samples four compositions NBT–xBT with x = 3, 6, 9, 12 mol. % BT were studied. Upon quenching, all demonstrate an rel...

Mesenteric arteries supplying an intestinal segment were occluded for 5 minutes and then released. During reperfusion, two series of measurements were made with various substances topically applied to the extraluminal surface. In the first series, reduced nitro blue tetrazolium (NBT) was extracted from tissue and measured spectrophotometrically, as an index of oxidative damage. In the second se...

Background: Persistently infected cells by herpesvirus (HSV, CMV, EBV) and their dysfunction are associated with different disorders. The immune and endocrine systems are involved in pathogenesis of herpesvirus infection. Changes of IFN-γ, IL-4, DHEAS and cortisol level are a part of the regulatory mechanisms of the immune and endocrine system responses in persistent herpesvirus infection. Obje...

Evidence confirms that nature-based therapy (NBT) has a positive effect on people with mental illnesses. However, there is a lack of evidence on the meaning of NBT for specific patient groups. The Nacadia® Therapy Garden was designed according to an evidence-based design process, and an NBT programme was developed. The aim of the study was to illuminate the phenomenon of participants' lived exp...

In vitro studies were conducted to determine whether conditioned medium from rat fetal urogenital sinus explants would affect phenotypic characteristics of NBT-II urinary bladder carcinoma cells in culture. NBT-II cells were exposed to medium (30%, v/v) conditioned for 48 h by intact urogenital sinus explants derived from 18-day fetal rats. Upon exposure for 23 h the [3H]thymidine incorporation...

Leucocyte function was evaluated by mobilisation to skin windows with chambers and by the chemotactic, phagocytic, and nitro blue tetrazolium (NBT) reducing activity of circulating leucocytes in vitro in 20 patients with Crohn's disease, 21 healthy volunteers, and nine patients with sarcoidosis or tuberculosis. Leucocytes had been mobilised in significantly reduced numbers at 12, 24, 36, and 48...

In order to meet the urgent need for high temperature piezoelectric materials with a Curie over 400 °C, Mn/Nb co-doped strategy has been proposed improve weak performance of Aurivillius-type Na0.5Bi4.5Ti4O15 (NBT) ceramics. this paper, crystal structure, electrical properties, and thermal stability B-site Na0.5Bi4.5Ti4-x(Mn1/3Nb2/3)xO15 (NBT-100x) ceramics were systematically investigated by co...
