The aim of this study was to evaluate and compare the cytotoxicity induced by two resin-based sealers, 2Seal and AH Plus, in two osteoblast-like cell lines, MG-63 and Saos-2. Using sterile discs of both sealers in complete media, 24- and 72-h extracts were prepared. The extracts were exchanged with Saos-2 or MG-63 cell culture media at 75% confluence, and after 24 h incubation, cell viability t...

Glyoxal (CHOCHO) is an atmospheric trace gas produced by the radical-initiated oxidation of hydrocarbons. High resolution measurements of the glyoxal absorption spectrum in the visible wavelength range are needed as reference spectra to calibrate optical spectroscopic measurements of this gas. The UV-vis absorption spectra of C13-disubstituted glyoxal and ambient (C12) glyoxal were collected at...

inflation forecasting has been one of the requirements for the implementation of monetary policy in countries which their monetary authorities are pursuing inflation targeting regime. however, owing to central bank independence in one hand and as well as the lagged effects of monetary policies on inflation in the other, the monetary authorities should have the sound perspective about the future...

Cisplatin is a common chemotherapeutic agent that used for treatment of many solid cancers. Rapid identification of chemotherapy resistance is very important and may lead to effective treatment plan. Spectroscopy techniques, such as infrared spectroscopy, which are sensitive to biochemical composition of samples, have shown potentials to discriminate tissues. Developing in Fourier transform inf...

Thirty group covariance data have been produced from ENDF/B VIII.0 MF 33 for H1, H2, He4, Li6, Li7, Be9, B10, B11, C12, C13, N15, O16, the JENDL O16 and F19. Multi-group cross section was by NJOY routine ERRORR. Negative eigenvalues were found only F19, but constraints required condition of sum partial sections being equal to resultant total be incorrect O16. An easy correction is suggested Li6...

1. Starch, containing 7.05 atom per cent C(13) excess has been produced in the mesophyll cells of bean leaves, starting with C(13)O(2) containing 7.26 atom per cent C(13) excess. Approximately 67 per cent of the C(13) taken up by the leaves was determined in the starch fraction. 2. The soluble carbohydrate, containing 6.72 atom per cent C(13) excess, accounts for approximately 23 per cent of th...

Immunoglobulin from goat antiserum directed against purified surface membranes from transformed BHK21/C13 cells (anti-M) has been shown to cause both control and transformed hamster cells to round and detach from the substrate (see accompanying paper). This paper documents the effects of the antiserum on the cytoskeletal organization and cell surface morphology of control BHK21/C13 cells examin...

zn (ii) is an important regulator of caspase-3, as well as an antioxidant, microtubule stabilizer, growth cofactor, and anti-inflammatory agent. over the past 30 years, many researchers have demonstrated the important role of zn (ii) in a variety of physiological processes, including growth and development, maintenance and priming of the immune system, and in tissue repair and regeneration. in ...

we investigated the effects of 25 mg-porphyrin-fullerene nanoparticles, ( 25 mgpmc16) smart ferroporphyrin nanoparticles, on pc12 cells exposed to oxygen-glucose deprivation/reperfusion. in order to explore its effect on cells under oxygen-glucose deprivation conditions, the cultures were pretreated with 25 mgpmc16 24 hours prior to oxygen-glucose deprivation/reperfusion. to initiate the oxygen...

objective(s) this study was carried out in order to evaluate the effects of electrochemotherapy, electrical pulses and chemotherapeutic drugs on the killing of cancerous cells and their probable synergistic effects. materials and methods electrochemotherapy treatments conducted on mcf-7 cell line derived from human breast adenocarcinoma tumor using four chemotherapeutic drugs including bleomyci...
