In the micropropagation of difficult-to-root plants, low rates rooting cause high economic losses. The local apple (Malus domestica Borkh.) cultivar #67, which is highly resistant to fire blight disease, has been shown have success. Nanoparticles loaded with auxins could increase success their physicochemical properties. To percentage, effects zinc oxide nanoparticles (nZnO), nZnO indole-3-acet...

objective: nano components are today’s new wonder material. however, the safety or toxicity of these components in humans is not yet clear. in a previous study we indicated that nano zno (nzno) has a stronger anxiolytic effect compared to the conventional zno (czno). the present study was designed to evaluate the intraperitoneal administration of an opioidergic receptor agonist and antagonist o...

The toxicity effects of silver (nAg) and zinc oxide (nZnO) engineered nanoparticles (ENPs) on the duckweed Spirodela punctuta were studied to investigate the potential risks posed by these ENPs towards higher aquatic plants. The influence of media abiotic factors on the stability of the ENPs was also evaluated. Marked agglomeration of ENPs was observed after introduction into testing media wher...

Introduction: Today Nano-medicine tries to produce new drugs to reduce the dosage and side effects of their conventional forms. According to the interaction between zinc and opioidergic system activity, this study has investigated the effect of new kind of zinc supplement, nano zinc oxide (nZnO), in compared to its conventional form (cZnO), in presence and absence of opioidergic system activity...

Phytotoxicity is an important consideration to understand the potential environmental impacts of manufactured nanomaterials. Here, we report on the effects of four metal oxide nanoparticles, aluminum oxide (nAl(2)O(3)), silicon dioxide (nSiO(2)), magnetite (nFe(3)O(4)), and zinc oxide (nZnO), on the development of Arabidopsis thaliana (Mouse-ear cress). Three toxicity indicators (seed germinati...

In this study, the phytotoxicity of seven metal oxide nanoparticles(NPs)-titanium dioxide (nTiO₂), silicon dioxide (nSiO₂), cerium dioxide (nCeO₂), magnetite (nFe₃O₄), aluminum oxide (nAl₂O₃), zinc oxide (nZnO) and copper oxide (nCuO)-was assessed on two agriculturally significant crop plants (maize and rice). The results showed that seed germination was not affected by any of the seven metal o...

BACKGROUND Doxorubicin (DOX), an anthracycline antibiotic, is a widely used anticancer agent. In spite of its high antitumor efficacy, the use of DOX in clinical chemotherapy is limited due to diverse toxicities, including gonadotoxicity. OBJECTIVE We investigated the protective effect of nano-zinc oxide (nZnO) as an established antioxidant on DOX-induced testicular disorders. MATERIALS AND...

INTRODUCTION Preventive resin restorations (PRR) are the conservative choice for the most common carious lesions in children. Thus, new age flowable resin composites with higher filler content are readily used. The aim of this study was to evaluate the microshear bond strength and microleakage of two flowable resin composites containing different percentages of nano zinc oxide (NZnO) particles,...
