Human serum albumin (HSA) is an abundant, multifunctional and nonglycosylated negatively charged plasma protein. HSA ascribed ligand-binding and transport properties, antioxidant functions and enzymatic activities. In the present study, the interaction and side effects of a new designed anti-cancer compound (1,10-phenanthroline butyl dithiocarbamato palladium(II) nitrate) on HSA have been inves...

The objective of this work was to investigate the potential of three different kinds of Iranian peat and swamp soils as sources of organic matter (OM) in the Golestan Province, Northern Iran. Comparison of the peats was done in terms of the degree of humification on the von Post scale. Moreover, the X-ray fluorescence, X-Ray Diffractometry, and Fourier transform infra-red (FT-IR) techniques wer...

In this paper synthesis and characterization of a bioactive calcium phosphate glass-ceramic is presented, synthesized using a facile method. The glass-ceramic samples are synthesized with heat treating the parent glass at appropriate temperatures, where different calcium phosphate crystalline phases are grown in the parent glass samples during the heat treatment. The amounts of elements a...

Scintillation single crystal fibers (SCFs) have great potential applications in the new generation of high-energy ray and particle detectors due to their morphological advantages. In this work; Ce:LuAG SCFs with a diameter 1 mm were grown along direction [111] by laser-heated pedestal growth (LHPG) method using transparent ceramic as source rod; doping concentration was 0.1 at%, 0.3 respectivel...

Dyes are an important class of pollutants which when discharged into water resources can be toxic to the aquatic environment and cause serious problems for public health. Various treatment technologies such as adsorption are in use. For this reason, clinoptilolite was used as a low-cost adsorbent to remove color from aqueous solution. Clinoptilolite was modified with sulfuric and phosphoric aci...

a reconnaissance study has been made on the distribution of 238u, 232th, 40k, 137cs andgeochemical features in soil and sediment samples at various locations on the coast of bushehr in the persiangulf. in this study a gamma-ray spectrometer based on a high purity germanium detector and a pc basedmca and x-ray fluorescence (xrf) method were used. estimation of the measured radionuclide contentha...

Six fluorescent compounds were isolated and characterized in rhizomorph of A. mellea and were presented first as: F , F , F , MF , MF and MF . These compounds differed by Rf on chromatoplaque, max in UV spectra and ex, em and max in fluorescence spectra. Their GC-MS analysis indicated that F has a phenolic moiety and the other five are the benzenic derivatives. F compound was more f...

We present a method based on photon migration of extracting intrinsic fluorescence spectra from turbid media, using concomitantly measured fluorescence and reflectance. Intrinsic fluorescence is defined as fluorescence that is due only to fluorophores, without interference from the absorbers and scatterers that are present. Application to fluorescence spectra taken with tissue phantoms and huma...

In a recent letter, Bokarev et al. [1] create a general relationship between state-dependent fluorescence yield and electron delocalization in L-edge x-ray absorption spectra based on 2p core-electron excitations into eg and t2g orbitals for three aqueous ionic species. In this Comment, we show that Bokarev et al. do not account for previous findings and that their claims are unsubstantiated. T...
