Purpose: To investigate the cytotoxic and antioxidant activities of the fruit and fruit waste (residue and marc) extracts of Antidesma thwaitesianum Müll. Arg., known as mamao in Thai, using chemical and cell-based assays. Methods: The cytotoxicity of mamao fruit and fruit waste extracts obtained by expression, maceration and decoction against a panel of six human cancer cell lines (COR-L23, A5...

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...

Storage of granulocytes for transfusion has not showed no functional impairment after 24 hr of been practical because it has been considered storage at 4#{176}C. With further storage, all granuthat granulocyte function in bank blood is relocytes showed a loss of NBT activity. Howtamed for only a few hours after collection. In ever, after 48 and 72 hr. granulocytes from the present study, granul...

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...

BACKGROUND AND THE PURPOSE OF THE STUDY Gnidilatimonoein (Gn), a new diterpene ester from Daphne mucronata, possesses strong anti-metastasis and anti-tumor activities. In this study, its apoptosis and differentiation capabilities were evaluated by using the leukemia HL-60 cell line. MATERIAL AND METHODS Cell prolifaration inhibition was estimated by MTT assay. The occurrence of apoptosis was ...

Leishmania parasites determine the outcome of the infection by inducing inflammatory response that suppresses macrophage's activation. Defense against Leishmania is dependent on Th1 inflammatory response by turning off macrophages' microbicidal property by upregulation of COX-2, as well as immunosuppressive PGE-2 production. To understand the role of L. donovani secretory serine protease (pSP) ...

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...
