Electrochemical behaviors of epinephrine and acetylcholine were investigated, using cyclic voltammetry, on the Ag-ZnO modified screen-printed electrode (Ag-ZnO/SPE). Ag-ZnO nanoplates showed excellent electrocatalytic activity toward the oxidation of epinephrine and acetylcholine compared with bare SPE in 0.1 M PBS. Under the optimized experimental conditions, a linear response obtained in the range of 0.13 to 450.00 μM with detection limit of 0.04 μM for epinephrine. Ag-ZnO/SPE exhibits good stability, reproducibility and repeatability, and the method has been successfully applied for detection of epinephrine and acetylcholine in their pharmaceutical and biological samples with satisfactory recovery.

Electronic band structures, the total density of state, the partial density of state, and optical properties were investigated using first principle method for SrPbO<sub>3</sub> though Generalized Gradient Approximation (GGA) based on the Perdew–Burke–Ernzerhof (PBE0). The band gap was recorded at 0.768 eV. The electron doping happens between similar electronic localized states of atoms in crystals where the section of the quality edge and electron quality of that is with thermally activated. The density of state and partial density of state were simulated for evaluating the nature of 5s, 4d for Sr, 6s, 4f, 5d, 6p for Pb and 2s, 2p for O atom for SrPbO<sub>3 </sub>orbital travelling with the maximum valance band (MVB) to the minimum conduction band (MCB) to explain the transition of electrons due to hybridization. The optical properties, for instance, absorption, reflection, refractive index, conductivity, dielectric function, and loss function, were calculated, which can account for the superior absorption of the visible light. The key point of this research is to determine the activity on electronics structure and optical properties for Fe doped by 6%. From the band gap and optical properties, SrPb<sub>0.94</sub>Fe<sub>0.06</sub>O<sub>3 </sub>can give more conductivity than that of SrPbO<sub>3, </sub>showing as a superconductor.

The new findings concerning synthesis of some 2, 4, 5-triaryl-<em>1H</em>-imidazoles is disclosed in the absence of any catalyst. Results indicated that by enhancing the amount of ammonium acetate, an obvious acceleration can be observed in the reaction progress. It is believed that ammonium acetate should be converted to ammonia and acetic acid during the reaction and the produced acid can catalyze the reaction progress. We believe that the observed efficiency for the previously reported catalytic systems has been mainly due to the presence of high molar ratio of ammonium acetate in the reaction medium and presence of auxiliary catalyst only improved the yield%.

The tripodalheptadentate Schiff base ligand, C<sub>21</sub>H<sub>27</sub>N<sub>7</sub>, was derived from pyrrole-2-carboxaldehyde with tris(2-aminoethyl)amine (tren) and its complexes with Cd(II), Co(II), Mn(II) and Ni(II) metal ions have been synthesized. The Schiff base and its metal complexes have been identified by IR, UV-Vis, <sup>1</sup>H-NMR, <sup>13</sup>C-NMR spectroscopy, elemental analysis and thermo gravimetric analysis (TGA). According to the spectroscopic and elemental analyses data, it was found that the Schiff base was coordinated to the metal ions as a potentially heptadentate ligand. All compounds showed antibacterial properties against the gram-positive bacteria; Bacillus cereus, Staphylococcus aureus, and gram-negative bacteria; Pseudomonas aeruginosa, Escherichia coli by using disc diffusion and micro-broth dilution methods. Also, the metal complexes showed a greater inhibitory effect than their individual ligand. Bacillus cereus was the most susceptible bacterial species to Co(II) complex while Escherichia coli required a relatively higher minimum inhibition concentration of Mn(II) complex.

The present study aimed to assess the adsorption of Lomustin on the single-walled carbon nanotube which has been examined using Density Functional Theory (DFT), agent in a solvent phase (water) at the B3LYP/6-31G (d) theoretical level. Initially, the structures of Lomustin, carbon nanotube, and Lomustin complexes with carbon nanotubes were designed in Gauss View in three different conformers and were optimized geometrically, on which IR and frontier molecular orbital computations were carried out. Adsorption energy values, Gibbs free energy changes (ΔG<sub>ad</sub>), adsorption enthalpy changes (ΔH<sub>ad</sub>), and equilibrium thermodynamic constants were estimated. The results showed that adsorption process was spontaneous, exothermic and non-equilibrium. The values of specific heat capacity and adsorption enthalpy indicate that this nanostructure can be used to build new thermal sensors to measure Lomustin. The results of molecule orbitals estimations showed that energy gap, after drug absorption on the nanotube surface, decreased significantly and the values of chemical hardness and dipole moment were studied after the interaction of drug with adsorbent and the results showed that drug solubility and reactivity, after adsorption on carbon nanotubes, increased significantly. According to the obtained results for adsorption of Lomustin, this nanostructure can be used as a sensing material in building new electrochemical sensors to measure this drug.

Background and purpose: Renal colic (RC) is observed in the urinary system and known with sudden and serious pain. Various analgesics are usually used for alleviating pain in the emergency department. This study compared the effect of Propofol with Fentanyl in controlling acute RC of patients admitted to the hospital. Methods: In this study, 150 patients referred to Shahid Mohammadi Hospital (Bandar Abbas-Iran) for the treatment of RC were selected. The basal pain values of the patients were investigated by the Visual Analogue Scale (VAS) that were in range from 0 up to 10 at the 0th, (immediately before drug administration), 15<sup>th</sup>, and 30<sup>th </sup>minutes. The zero value shows lack of pain and highest value (10) means the severe pain. Results: The results showed that VAS value was significantly higher in VAS0 compared to VAS10 and VAS30 for all the groups (<em>P</em><0.05). The results also showed a significant difference between Morphine, Propofol and Fentanyl for VAS10 and VAS30 (<em>P</em><0.05). The results showed that values for VAS were 3.66, 1.19 and 5.05 for Morphine, Fentanyl and Propofol groups, respectively. The values for VAS30 were 2.85, 1.19 and 3.52 for Morphine, Fentanyl and Propofol groups, respectively. The lowest value was observed for Fentanyl and the highest value was observed in Propofol group for VAS10 and VAS30. Conclusion: The best response was observed in Fentanyl group and it can be recommended using Fentanyl for controlling acute renal colic and its hydronephrosis in patients admitted to the hospital.

The present study designed an electro-chemical instrument with high sensitivity and selectivity on the basis of a SPE modified with La<sup>+3</sup>/Co<sub>3</sub>O<sub>4</sub> nano-cubes in order to analyze vitamin B<sub>9</sub>. It was confirmed that this sensor possesses very good electron-moderating behaviors to oxidize vitamin B<sub>9</sub> in a 0.1 M phosphate buffer solution (PBS) (pH=7.0). In addition, according to optimal conditions (pH=7.0), a potential around 110 mV less positive than the one in the un-modified electrodes is required for vitamin B<sub>9</sub> oxidation at this electrode surface. This technique limit of determination for vitamin B<sub>9</sub> has been estimated to be 0.3 μM (S/N = 3). Responses have been linear in concentrations range between 1.0 and 600.0 μM. The modified electrode has been applied to detect vitamin B<sub>9</sub> in real specimens, which was accompanied by acceptable outputs. Experiments showed that La<sup>+3</sup>/Co<sub>3</sub>O<sub>4</sub> nano-cubes will be valuable electrode materials providing a high ratio of surface to volume that enhances sensitivity. The study introduces a novel sensor with simpleness, quickness, sensitivity, and affordability features to quantify vitamin B<sub>9</sub>.

The aim of the study is to investigate sweeting process of sour gas by dynamic simulation of monoethanolamine (MEA) molecule. In the present paper using molecular dynamic simulation, the interaction of sour gas mixture included methane, ethane and H<sub>2</sub>S with MEA as absorption was also investigated the quantum method DFT B3LYP 6-311 (+) G** was used for electric charge calculation. The simulation results confirmed that the tendency of the H<sub>2</sub>S molecule is to be absorbed to amine nitrogen and oxygen hydroxyl group in MEA. No tendency for strong interaction between sulfur atoms of H<sub>2</sub>S molecule and hydrogen of amine or hydroxyl groups was observed. The investigation of changing distance between the hydrogen of H<sub>2</sub>S and nitrogen/oxygen of MEA confirmed a stable between hydrogen atoms of H<sub>2</sub>S and nitrogen/oxygen atoms in MEA. Also the investigation of distance changing show movement of hydrogen atoms of H<sub>2</sub>S molecule which interacted with MEA molecule in the time frame of the simulation. This study was observed that after absorption of H<sub>2</sub>S molecule by MEA molecules sour of them made the bridge for connection of MEA molecules with each other. Actually H<sub>2</sub>S molecules after interact with MEA molecules used addition their free hydrogen forinteraction and Making Bridge. Finally a structure of some MEA molecules are joined together, which are stable up to end of the simulation.
