Abstract
Plenty of reports focus on the effects of low-dose radiation (LDR) on peripheral blood lymphocytes in radiation workers. However, studies on red blood cells (RBCs) in radiation workers are rarely reported. Many studies focused on investigate the hemogram of radiation staffs without detecting other components of RBCs. To explore the potential effect of LDR on RBCs, we detected the level of RBC count, hemoglobin, 2,3-disphosphoglycerate (2,3-DPG), and glutathione (GSH), and then analyzed the factors on these indices in 106 medical radiation workers. As a result, RBC count was affected by sex, age, type of work, length of service (only for females), and annual effective dose (only for males). Hemoglobin status was affected by sex, type of work, and annual effective dose (only for males). Sex, age, and type of work had no effects on the concentration of 2,3-DPG and GSH. Length of service affected 2,3-DPG concentration, and annual effective dose affected GSH level. In conclusion, chronic occupational LDR exposure may have an effect on RBC count, hemoglobin status, and the concentration of 2,3-DPG and GSH in radiation workers to some extent. However, it is still unknown how this kind of influence affects the health of radiation workers.

Abstract
Silver ions (Ag+) can be released by silver nanoparticles (AgNPs) which are widely used in diverse fields. Ag+ can exist inside cells to produce cytotoxicity. This report uses spectroscopic methods to reveal the interactions between Ag+ and bovine hemoglobin (BHb). The results of the quenching rate constant (Kq) and the fluorescence lifetime detection showed that the quenching mechanism of BHb by Ag+ was static. Thermodynamic investigations indicated that Ag+ can interact with BHb with one binding site to form complex mainly through van der Waals interactions and hydrogen bonds. The UV-vis absorption and synchronous fluorescence spectra showed that Ag+ changed the conformation of BHb, which may affect protein functions. This research is favorable for understanding the molecular toxic mechanism of Ag+ in vivo.

Abstract
Eu(3+) doped CdS nanocrystals (CdS:Eu NCs) were synthesized via a co-precipitation method. The doping of Eu(3+) ions caused a 4-fold enhancement in electrochemiluminescence (ECL) intensity and more stable cathodic signals compared to pure CdS NCs. Such enhancement was mostly ascribed to doping-induced improvement in the stability of reduced NCs. A new emission peak around 620 nm was observed in ECL spectra of the doped NCs, which belongeded to the (5)D(0)→(7)F(2) transition of Eu(3+) ions in CdS NCs. Correspondingly, a pair of oxidation and reduction peaks occurred at +1.01 V and +0.61 V because of the formation of Eu(3+)-surface states complex when the CdS:Eu NCs solution underwent cyclic voltammogram scanning. Benefiting from the strong ECL emission of the doped NCs and high affinity of the doped Eu(3+) ions to oxygen, the CdS:Eu NCs film showed a great oxygen-sensitivity. The intense red luminescence of the characteristic transitions of Eu(3+) in CdS:Eu NCs would also have enormous potential in bioanlytical systems.

Abstract
The binding reaction between docetaxel (DTX) and human hemoglobin (HHb) was investigated systematically with various spectroscopic methods including fluorescence quenching technique, ultraviolet (UV)-vis absorption, synchronous fluorescence, circular dichroism (CD) and Fourier transform infrared (FT-IR) spectroscopy. Analysis of fluorescence data showed that the quenching mechanism was the dynamic quenching and each protein had only one binding site for the drug. Two thermodynamic parameters, the enthalpy change and the entropy change were calculated to be 9.18 kJ mol(-1) and 116J mol(-1) K(-1), respectively, which suggested that hydrophobic interaction played a major role in the binding reaction. The results from different spectroscopic methods also showed that DTX could induce conformational changes of HHb. The molecular docking simulation demonstrated that DTX was located in the central cavity of HHb.

Abstract
The spectroscopic properties of interactions involving horseradish peroxidase (HRP) and Tb3+ in the simulated physiological solution was investigated with some electrochemical and spectroscopic methods, such as cyclic voltammetry (CV), circular dichroism (CD), X-ray photoelectron spectroscopy (XPS) and synchronous fluorescence (SF). It was found that Tb3+ can coordinate with oxygen atoms in carbonyl groups in the peptide chain of HRP, form the complex of Tb3+ and HRP (Tb-HRP), and then lead to the conformation change of HRP. The increase in the random coil content of HRP can disturb the microstructure of the heme active center of HRP, in which the planarity of the porphyrin cycle in the heme group is increased and then the exposure extent of the electrochemical active center is decreased. Thus Tb3+ can inhibit the electrochemical reaction of HRP and its electrocatalytic activity for the reduction of H2O2 at the Au/Cys/GC electrode. The changes in the microstructure of HRP obstructed the electron transfer of Fe(III) in the porphyrin cycle of the heme group, thus HRP catalytic activity is inhibited. The inhibition effect of Tb3+ on HRP catalytic activity is increased with the increasing of Tb3+ concentration. This study would provide some references for better understanding the rare earth elements and heavy metals on peroxidase toxicity in living organisms.

Abstract
The interaction between human adult hemoglobin (Hb) and bare CdS quantum dots (QDs) was investigated by fluorescence, synchronous fluorescence, circular dichroism (CD), and Raman spectroscopic techniques under physiological pH 7.43. The intrinsic fluorescence of Hb is statically quenched by CdS QDs. The quenching obeys the Stern-Volmer equation, with an order of magnitude of binding constant (K) of 10(7). The electrostatic adsorption of Hb on the cationic CdS QDs surface is energetically favorable (DeltaS(0)=70.22 Jmol(-1)K(-1), DeltaH(0)=-23.11 kJmol(-1)). The red shift of synchronous fluorescence spectra revealed that the microenvironments of tryptophan and tyrosine residues at the alpha(1)beta(2) interface of Hb are disturbed by CdS QDs, which are induced from hydrophobic cavities to a more exposed or hydrophilic surrounding. The secondary structure of the adsorbed Hb has a loose or extended conformation for which the content of alpha-helix has decreased from 72.5 to 60.8%. Moreover, Raman spectra results indicated that the sulfur atoms of the cysteine residues form direct chemical bonds on the surface of the CdS QDs. The binding does not significantly affect the spin state of the heme iron, and deoxidation is not expected to take place on the coated oxyhemoglobin. The change of orientation of heme vinyl groups was also detected.
