This research has been done to study characteristic and biocompatible evaluation of a nano-biocompositeceramic with the bioglass (BG) as a first phase. In this regard, synthesis of S53P4 (53% SiO2, 4% P2O5,23% Na2O and 20% CaO) bioglass has been considered as the first phase and flourapatite (FA) consideredas the second phase. Afterwards, nanocomposite with the base of S53P4 b...

The development and optimization of an automated flow injection (FI) manifold coupled with a Fourier transform infrared (FT-IR) detector for the determination of toluene, ethyl benzene and o-xylene in an n-hexane matrix is described. FT-IR parameters optimized were resolution and number of co-added scans; FI parameters optimized were type of pump tubing, carrier flow rate and sample volume. ATR...

BACKGROUND Drugs designed to restore programmed cell death might be effective against many cancer. It was aimed to study the possible apoptotic-necrotic effects of the pyridinehalide complexes such as dichlorodipyridinepalla-dium(ll) (PdCl2L1(2)), dichlorodipyridinenickel(ll) (NiCl2L1(2)), dichlorodipyridinecopper(ll) (CuCl2L1(2)), dibromodipyridinecopper(ll) (CuBr2L1(2)) and dichlorobis-(2,4-d...

BACKGROUND Lower levels of cytosine methylation have been found in the liver cell DNA from non-obese diabetic (NOD) mice under hyperglycemic conditions. Because the Fourier transform-infrared (FT-IR) profiles of dry DNA samples are differently affected by DNA base composition, single-stranded form and histone binding, it is expected that the methylation status in the DNA could also affect its F...

BACKGROUND Glioma is the most common primary brain tumor with poor prognosis. Temozolomide (TMZ) has been used with irradiation (IR) to treat gliomas. The aim of the present study was to evaluate the cytotoxic and radiosensitizing effect of TMZ when combined with high-dose and high-dose rate of gamma irradiation in vitro. METHODS Two 'U87MG' cell lines and skin fibroblast were cultured and as...

Fourier transform infrared (FT-IR) spectroscopy combined with multivariate statistical analyses was investigated as a physicochemical tool for monitoring secreted recombinant antibody production in cultures of Chinese hamster ovary (CHO) and murine myeloma non-secreting 0 (NS0) cell lines. Medium samples were taken during culture of CHO and NS0 cells lines, which included both antibody-producin...

The application of single-pass attenuated total reflection Fourier transform infrared (ATR-FT-IR) microscopy was investigated for secondary structure analysis of 15 representative proteins in H2O solution. This is the first reported application of single-pass ATR-FT-IR for protein analysis; thus, the method was validated using transmission FT-IR and multipass ATR-FT-IR as referee methods. The s...
