This research is devoted to studying the radiation-protecting characteristics of calcium titanate (CaTiO3) perovskite-based ceramic material. The ceramics were made by solid-state reaction method (SSRM) and treated at temperatures 1300 °C, 1200 1100 °C. structural analyzed XRD FT-IR. results indicated a CaTiO3 phase formation with an orthorhombic structure. size crystallites was in range 27–36 ...

h. pylori  is a human pathogen that colonizes the epithelium of the stomach. the host immune response may influence the disease process, where cytokines play important roles in the development of disease. in this study, the concentrations of selected cytokines in the gastric antrum and stomach body mucosa and also in the serum were evaluated. eighty patients according to their rapid urease test...

objective: some evidence suggests that chronic uptake of estragole and methyl-eugenol, found in the essential oil of artemisia dracunculus (tarragon), may be associated with an increased risk of hepato-carcinogenicity. the present study was conducted to investigate the immumodulatory and anti-inflammatory potentials of estragole and methyl-eugenol free extract of tarragon. materials and methods...

Abstract PLA and its nanocomposite containing 3% chitosan nanoparticles (PLA-3CsNP) were studied to see how γ -irradiation affected their characteristics. Different doses of applied the investigated materials under inquiry (5–40 kGy) using 60 Co at ambient conditions. The irradiation characterized by FT-IR, GPC, mechanical tensile test, DSC, XRD, TGA in solid chloroform solutions. molecular wei...

The effect of medium doses of γ-irradiation (1-10 kGy) on total phenolic and tannin contents, lipid peroxidation, protein oxidation intensity and soluble protein content of soybean seeds, (genotype Ana), was investigated. Screening for antioxidant ability was performed using FRAP and DPPH methods. Total phenolic and tannin contents and DPPH scavenger activity were increased, while protein oxida...

background: tuberculosis is a disease with high morbidity, caused mainly by mycobaterium tuberculosis (m.tb.). dna vaccines show a promising future due to their unique advantages over conventional methods. the early-secreted antigen target (esat)-6 and culture filtrate protein (cfp)-10 of m.tb. antigens have been identified as vaccine candidates against mycobacteria and used as subunit vaccines...

Peroxisome proliferator-activated receptor-γ (PPAR-γ) is important in tumor differentiation, proliferation and apoptosis. However, the effect and mechanism of PPAR-γ on the promotion of cisplatin sensitivity in glioma cells remain to be elucidated. The present study established cisplatin-resistant U-87 MG/CDDP cell lines and U-87 MG/CDDP cell lines overexpressing PPAR-γ. With upregulated expres...

PURPOSE Specific oral immunotherapy (SOIT) using interferon-γ (IFN-γ) has been successful as a food allergy treatment. Interleukin-10 (IL-10)-producing regulatory B cells (Br1s) play a role in immune tolerance to food allergens. In addition, IFN-γ shows tolerogenic effects on allergen-induced Br1 responses. METHODS Eleven patients that were allergic to cow's milk and 12 milk-tolerant subjects...
