Objective: Depression affects people living with HIV(PLWH) compliance leading to poor control *** observational studies showed an anti-depression effect of green tea extract(GTE). The therapeutic effect of GTE on depression were investigated in PLWH receiving antiretroviral therapy(ART).Methods: Fifty PLWH on ART with diagnose of mild to moderate of depression, participated in a doubleblind, placebo-controlled trial and underwent 12 weeks of treatment with either 400 mg GTE capsules or placebo twice daily. The Hamilton depression scale of patients was measured before, 6 weeks and 12 weeks after treatment in two groups. The primary outcome measure was performed to evaluate the efficacy of GTE in improving depressive ***: The mean of Hamilton score showed a significant difference between the two groups after 12 weeks(P = 0.035). Repeated measures ANOVA test showed a significant effect for time ? treatment interaction on the Hamilton mean score between the two groups(P = 0.000).Conclusion: It seems the use of GTE capsules in PLWH on ART is safe and could lead to greater and more rapid improvement in depressive symptoms than placebo. Thus it can be considered as an alternative therapy for mild to moderate depression. Further studies with higher sample size and longer followup and comparisons with other antidepressive drugs are warranted.

Influence of Specimen Geometry of Hot Torsion Test on Temperature Distribution During Reheating Treatment of API-X70

引用

Journal of Iron and Steel Research International 2010年第3期17卷 34-39页

作者： Bahman Mirzakhani Shahin Khoddam Hossein Arabi mohammad Taghi salehi Seyed Hossein Seyedein mohammad reza Aboutalebi Faculty of Engineering Arak University Department of Mechanical Engineering Monash UniversityClayton Campus Department of Materials and Metallurgical Engineering Iran University of Science and Technology

The commercial finite element package ANSYSTM was utilized for prediction of temperature distribution during reheating treatment of hot torsion test （HTT） samples with different geometries for API-X70 microalloyed steel. Simulation results show that an inappropriate choice of test specimen geometry and reheating conditions before deformation could lead to non-uniform temperature distribution within the gauge section of specimen. Therefore, assumptions of isothermal experimental conditions and zero temperature gradient within the specimen cross section appear unjustified and led to uncertainties of flow curve obtained. Recommendations on finding proper specimen geometry for reducing temperature gradient along the gauge part of specimen will be given to create homogeneous initial microstructure as much as possible before deformation in order to avoid uncertainty in consequent results of HTT.

Electrooxidation of hydroquinone on simply prepared Au-Pt bimetallic nanoparticles

引用

Science China Chemistry 2013年第6期56卷 746-754页

作者： ETESAMI mohammad KAROONIAN Fatemeh salehi MOHAMED Norita School of Chemical Sciences Universiti Sains Malaysia (USM)

A facile method was used to prepare gold-platinum （Au-Pt） catalysts by direct electrodeposition via cyclic voltammetry in an acidic medium. Various parameters that affect the properties of electrodeposited catalysts were investigated such as initial ap- plied potential, scan rate and deposition time. Initial applied potential plays a more important role in the preparation of bime- tallic nanoparticles （AuPtNPs） since the kinetics of electrodeposition is in competition with the rate of hydrogen evolution. The AuPtNPs electrodeposited on pencil graphite （PG） were used to study the electrooxidation of hydroquinone. Various parame- ters such as pH, scan rate, concentration of hydroquinone and temperature were studied in the electrooxidation process. Ap- parent activation energy （Ea） for the electrooxidation of hydroquinone, calculated from the Arrhenius plot, shows that AuPtNPs catalysts （electrodeposited on the PG） offer less activation energy （ca. 9.500 kJ mo1-1） than the bare PG （ca. 10.345 kJ mol-1）. The AuPtNPs/PG shows better catalytic performance than the PG electrode due to the greater surface area it provides, thus re- sulting in more active sites available for adsorption of hydroquinone molecules on the surface of the catalyst.
