Carbon nanotubes
(Journal of the Serbian Chemical Society, 2008)
Nanotubes, the last in the focus of scientists in a series of all carbon materials discovered over the last several decades arc the most interesting and have the greatest potential. This review aims at presenting in a ...
Comparative analysis of tryptophan oxygenase activity and glucocorticoid receptor under the influence of insulin
(Physiological Research, 2008)
This investigation addresses the interaction of insulin (INS) and glucocorticoid (GC) signaling in the hepatic regulation of tryptophan oxygenase (TO) enzyme activity in the rat. Male Wistar rats (200-250 g b.w) received ...
The brightness of the galactic radio loops at 1420 MHz: Some indications for the existence of Loops V and VI
(Astronomische Nachrichten, 2008)
In this article we use 1420 MHz data to demonstrate the likely reality of Galactic radio Loops V and VI. We further estimate distances and spectral indices for both these and the four main radio loops. In the cases of Loops ...
Molecular characteristics and prognostic significance of bcl-2/IgH gene rearrangement in Serbian follicular lymphoma patients
(Neoplasma, 2008)
Follicular lymphoma (FL) is characterized by the presence of a t(14; 18) chromosomal translocation that results in overexpression of bcl-2 protein. Bcl-2/IgH gene rearrangement is detected in 80-90% of follicular lymphomas ...
Early effects of gamma rays and protons on human melanoma cell viability and morphology
(Journal of Microscopy, Oxford, 2008)
The effects of irradiation with gamma rays and protons on HTB140 human melanoma cell morphology and viability were analyzed. Exponentially growing cells were irradiated close to the Bragg peak maximum of the 62-MeV proton ...
Gel combustion synthesis of transition metal ions doped Zn2SiO4 powder
(Journal of Optoelectronics and Advanced Materials, 2008)
We present here the synthesis procedure for obtaining Zn2SiO4:M2+ (M = Mn, Ni, Co) powder based on the combination of so-gel and combustion methods. Combustion is performed both in a conventional furnace and in a microwave ...
A kinetic study of the thermal decomposition process of potassium metabisulfite: Estimation of distributed reactivity model
(Journal of Physics and Chemistry of Solids, 2008)
The thermal decomposition kinetics of potassium metabisulfite was studied by thermogravimetric (TG) and differential thermogravimetric (DTG) techniques using non-isothermal experiments. The apparent activation energy (E-a) ...
Nanoparticle shape and configuration analysis by transmission electron tomography
(Journal of Microscopy, Oxford, 2008)
Tomographic reconstruction by transmission electron microscopy is used to reveal three-dimensional nanoparticle shapes and the stacking configurations of nanoparticle ensembles. Reconstructions are generated from bright-field ...
Preparation of biomorphic SiC ceramics
(Science of Sintering, 2008)
This paper deals with a new method for producing non-oxide ceramic using wood as a template. SiC with a woodlike microstructure has been prepared by carbothermal reduction reactions of Tilia wood/TEOS composite at 1873K. ...
Particle size analysis: (90)Y and (99m)Tc-labelled colloids
(Journal of Microscopy, Oxford, 2008)
Colloidal particle size is an important characteristic to consider when choosing a radiopharmaceutical for diagnosis and therapeutic purposes in nuclear medicine. Photon correlation spectroscopy (PCS) and transmission ...
