background: saffron, the dried stigmas of crocus sativus, is the world's most expensive spice which has been used as food additive and flavoring agent. the aim of the present study has been to investigate the combination effects of gamma irradiation and silver nano particles packing on the chemical properties of saffron during storage time. a combination of hurdles can ensure stability and...

Introduction: Nowadays, the main focus of dental studies is on adhesive dental materials; since clinical long-term success of bonded restorations depended more on marginal microleakage minimization. So, the aim of this study was Evaluation of Diode laser irradiation effect on microleakage in class V composite restoration before and after adhesive application. Materials and methods: In this in v...

Objective(s): Curcumin, a natural plant product, is commonly known as wonder drug of life, but the poor bioavailability of its free form has hindered its clinical development. The aim of the present study was to investigate the radioprotective effect of nanocurcumin on survival of mice under whole body X-ray irradiation. Materials and Methods: The Naval Medical Research Institute (NMRI) mice ra...

The effect of post-irradiation annealing on the microstructures and mechanical properties of V-4Cr-4Ti alloys was studied. Helium-hydrogen-irradiated sequentially V-4Cr-4Ti alloys at room temperature (RT) were undergone post-irradiation annealing at 450 °C over periods of up to 30 h. These samples were carried out by high-resolution transmission electron microscopy (HRTEM) observation and nanoi...

intravenous laser blood irradiation was first introduced into therapy by the soviet scientists en.meschalkin and vs.sergiewski in 1981. originally this method was developed for the treatment of cardiovascular diseases. improvement of rheologic properties of the blood as well as improvement of microcirculation and reduction of the area of infarction has been proved. further, reduction of dysrhyt...

in the present study, aminoazines were prepared from the reaction of amidrazone hydroiodide with various aromatic aldehydes in the presence of a solid base under microwave irradiation with power level of 850 w for 2-7 min in high yields. the amidrazone hydroiodide can also be prepared by the reaction of s-methyl isothiobenzamide hydroiodide and hydrazine in methanol under nitrogen gas. all synt...

Radiotherapy is a common and effective treatment for many cancers. For most cancers, however, normal tissues are inevitably co-irradiated. This may lead to severe toxicity. For tumours in e.g. the thoracic region, this limits treatment dose and efficacy. Therefore, development of particle therapy aimed at minimizing dose and volume to which the normal tissues are irradiated. Particles such as c...

The effect of ultraviolet irradiation on fluorinated graphene (FG) dispersed in toluene was investigated for the first time. The chemical and physical characteristics of FG before and after ultraviolet irradiation were analyzed by UV-vis, FTIR, XPS,EDS, oxygen flask combustion (OFC), XRD, TGA, Raman, SEM, TEM and fluorescence spectroscopy. It is found that the F/C ratio initially decreases rapi...

The effect of kalonji (Nigella sativa) extract (NSE) was studied on dermal excision wound of mice whole body exposed to different doses of γ-radiation. The optimum dose was selected by administering mice with different doses of NSE for five consecutive days before whole-body exposure to 6 Gy γ-radiation and creating a full thickness deep dermal wound of 15 mm diameter on the dorsum of mice afte...

BACKGROUND AND PURPOSE Pneumonitis and fibrosis constitute dose-limiting side effects of thorax or total body irradiation. An improved understanding of the underlying mechanisms is a prerequisite for the development of effective radioprotective strategies. Here we characterized the behavior of resident and immune cells in a murine model of radiation-induced pneumopathy. MATERIALS AND METHODS ...
