An in vitro cultivation method for spleen and head kidney organ section were used to investigate the eff ects of levamisole on the immune response. After 10 days of culture with 10 μg/ml, 50 μg/ml and 100 μg/ml or no levamisole in the culture media, the non specific defense reaction were measured by glass-adherent NBT (nitroblue tetrazolium) positive cells activation and phagocytic activity. El...

Quenching relaxor ferroelectric 0.94(Na1/2Bi1/2)TiO3–0.06BaTiO3 (NBT-6BT) enhances the depolarization temperature (Td), linked to stabilization of order. The thermal evolution domain structure and phase assemblage provides insights about onset order in quenched materials. Unpoled furnace cooled NBT-6BT ceramics were studied using situ temperature-dependent transmission electron microscopy. rhom...

A new acetylenic alkaloid was isolated from the sponge Leucetta sp. The structure was established by analyzing spectroscopic data. The alkaloid showed cytotoxicity IC₅₀ 2.5 μg/mL against NBT-T2 cells.

A comparison between the NBT-PABA/14C-PABA test (NBT-PABA, n-benzoyl-tyrosyl para-aminobenzoic acid) using the PABA excretion index (PEI) and serum PABA estimation at 90 minutes has been made in 42 consecutive subjects attending for investigation of possible pancreatic disease to a District General Hospital (DGH). The PEI was unobtainable or incorrect on 38% of occasions compared with 9% for th...

Multiple effects of ozone are a prerequisite for its use in the complex therapy inflammatory bowel diseases. Our aim was to analyze and 5-aminosalicylic acid (5-ASA) oxazolone-induced colitis (OIC) upon innate immunity functions.
 OIC modeled 72 male Wistar rats weighing 24020 g by two-stage application oxazolone solution. Ozone at dose 0.05 mg/kg, as part ozone-oxygen mixture, injected in...

The aim of this study was to evaluate the oxidative stress in ovaries and corpus luteum (CL) Bos taurus indicus females oxidant effect CL ovarian tissues regions near, intermediate, or distant from it. Ovaries (n=12) Nelore heifers (n=6) were collected a slaughterhouse fragmented. Experiment 1, each ovary obtained three fragments, resulting 18 fragments with (OV+CL) another without (OV-CL). Thr...

In this work, the dependency of polarization (P) - electric field (E) loop area A lead free ferroelectrics Na0.5Bi0.5TiO3 (NBT), K0.5Bi0.5TiO3 (KBT), and Na0.25K0.25Bi0.5TiO3 (NKBT) on amplitude (E0) is studied. Based nature hysteresis with increasing E0, lnA versus lnE0 graph divided into three stages scaling exponents each stage are estimated. third stage, NBT, KBT, NKBT show different shapes...

Enhanced pyroelectric response is achieved via domain engineering from [001] grain-oriented, tetragonal-phase, lead-free 0.2(2/3K0.5Bi0.5TiO3-1/3BaTiO3)-0.8Na0.5Bi0.5TiO3 (KBT-BT-NBT) ceramics prepared by a templated grain growth method. The crystallographic orientation leads to large polarization in tetragonal symmetry; therefore, texturing along this direction employed enhance the pyroelectri...

In the course of screening for antioxidant compounds by measuring the radical scavenging effect on DPPH (1,1-diphenyl2-picrylhydrazyl), a total extract of the twigs of Vitex rotundifolia (Verbenaceae) was found to show potent antioxidant activity. Subsequent activity-guided fractionation of the methanolic extract led to the isolation of three iridoid compounds, 10-O-vanilloylaucubin (1), 10-O-p...
