CoO NPs@N-PC nano-architecture has high specific surface areas (250 m g) and is a non-toxic, effective and stable PMS activator.

Given their dimensions, these materials have considerable surface/volume ratios, and hence, specific characteristics. Nowadays, environmentally friendly procedures are being proposed for fabrication of Fe nanoparticles because a large amount of poisonous chemicals and unfavorable conditions are needed to prepare them.

During the past years, titanium dioxide nano-architectures (TiO NAs) have been widely used in water purification applications with photocatalytic degradation processes under Uv/Vis light illumination. Photocatalysis process with nano-architectural design of TiO is viewed as an efficient procedure for directly channeling solar energy into water treatment reactions.

The preparation of a magnetic three-dimensional (3D) spongin scaffold with nano-sized FeO cores is reported here for the first time. The formation of this magnetic spongin-FeO composite was characterized by X-ray diffraction (XRD), thermogravimetric analysis (TGA), differential thermal analysis (DTA) (TGA-DTA), vibrating sample magnetometer (VSM), Fourier-transform infrared spectroscopy (FTIR), and zeta potential analyses.

In comparison to bare ZnFeO and ZnO, the ZnFeO-ZnO@N/B/RGO and ZnFeO@ZnO-CN ternary products showed highly improved photocatalytic properties in the degradation of methyl orange (MO) under ultra-violet (UV) and visible light irradiation. Various physicochemical properties of the photocatalysts were evaluated through field emission scanning electron microscopy (FESEM), energy-dispersive X-ray (EDX) analysis, X-ray diffraction (XRD), UV-visible diffuse reflectance spectroscopy (DRS), Fourier transform infrared spectroscopy (FT-IR), and vibrating sample magnetometer (VSM) techniques.

It is known as "drug of aggression" because of its very strong and long-lasting effects on the central nervous system. The sedative influence of flunitrazepam drug increases with alcohol drinking, which causes mental and motor disorders and causes the victim to become silent.

In the present study, we will assess chronic and occult HBV and isolated anti-Hepatitis B core antigen whose screening and evaluation is not routine in different populations.
Materials And Methods: This descriptive analytical study was conducted on 213 patients undergoing chemotherapy - radiotherapy referred to the hematology - oncology clinics of Isfahan, Iran in 2012.
Background: Immunodeficiency is a heterogenous group of diseases affecting different components of the immune system. Patterns of infection, etiology and organ involvement are not similar in this risky population. This study was conducted to determine the prevalence of congenital and acquiring immunodeficiencies and also recognizing the most common infections and affected organs.

Since rates of hospitalization and mortality due to the disease have varied widely in different countries, we described the clinical, radiologic, and demographic features of H1N1 hospitalized patients in a hospital in Isfahan.
Methods: This cross-sectional study was conducted in Alzahra Hospital during September 2009 to February 2010.
Background: Nowadays, coronary artery bypass graft (CABG) is a frequent surgery in treatment of coronary artery disease. According to high expense of this surgery and its important role in patients' quality of life, high survival rate of patients and success of surgery are necessary. The aim of this study was the evaluation of fever incidence (febrile events) due to incidence of pneumonia, wound infection, bacteremia, urinary tract infection and inflammatory response without infection after CABG.
