Background: The spread of pathogenic microorganisms in food and beverage and their resistance to antibiotics have raised major concerns for public health. The aim of this study was to investigate the antimicrobial activity of various metal oxide nanoparticles (NPs) including zinc oxide (ZnO), magnesium oxide (MgO), and iron oxide (Fe2O3) NPs against Staphylococcus aureus (S. aureus) and Esch...

INTRODUCTION Eosinophilic and noneosinophilic Nasal polyps (NPs) are different subtypes of NPs and require different treatment methods. OBJECTIVE To compare the histologic characteristics, mRNA and protein expression between Nasal Polyps with and without eosinophilia. METHODS NPs tissues were obtained from eighty-six NPs patients during surgery. Eosinophilic and noneosinophilic NPs were dis...

Patients with metastatic castration-resistant prostate cancer (mCRPC) have poor outcomes. Docetaxel (DTX)-based therapy is a current standard treatment for patients with mCRPC. Approaches combining conventional chemotherapeutic agents and nanoparticles (NPs), particularly iron oxide NPs, may overcome the serious side effects and drug resistance, resulting in the establishment of new therapeutic...

Nanomaterials have an advantage in "personalized" therapy, which is the ultimate goal of tumor treatment. In order to investigate the potential ability of FePt nanoparticles (NPs) in the diagnosis and chemoradiotherapy treatment of malignant tumors, superparamagnetic, monodispersed FePt (~3 nm) alloy NPs were synthesized, using cysteamine as a capping agent. The NPs were characterized by means ...

background; in recent years, nanoparticles have been increasingly used in industries. however, there is a serious lack of information concerning their impact on human health and the environment. this study was investigated the effect of moo3 nps on thyroid hormones in female rats. methods; in this study, 21 female wistar rats were selected and divided into three groups of untreated control, sha...

Nanotechnology has advanced at an extremely rapid pace over the past several years in numerous fields of research. However, the uptake of nanoparticles (NPs) into the body after administration through various routes may pose a risk to human health. In this study, we investigated the potential ocular toxicity of 20-nm, negatively- charged zinc oxide (ZnO) NPs in rats using micro-computed tomogra...

We report the synthesis of smart nanoparticles (NPs) that generate heat in response to an alternating current magnetic field (ACMF) and that sequentially release an anticancer drug (doxorubicin, DOX). We further study the in vivo therapeutic efficacy of the combination of magnetic hyperthermia (MHT) and chemotherapy using the smart NPs for the treatment of multiple myeloma. The smart NPs are co...

objective(s): silver nanoparticles (ag-nps) are one of the most widely used nanomaterials recently. despite the wide application of nanomaterials, there is limited information concerning their impact on human health and the environment. this study aimed to find the effects of ag-nps (40 nm) on blood serum, liver and kidney tissues of homing pigeons (columbia livia).materials and methods: columb...

Zinc oxide (ZnO) nanoparticles (NPs) are used in diverse applications ranging from paints and cosmetics to biomedicine and food. Although micron-sized ZnO is a traditional food supplement, ZnO NPs are an unknown public health risk because of their unique physicochemical properties. Herein, we studied the 13-week subchronic toxicity of ZnO NPs administered via the oral route according to Organiz...

Purpose Erlotinib (ETB) is a well-established therapeutic for non-small-cell lung cancer (NSCLC). To overcome drug resistance and severe toxicities in the clinical application, redox-responsive and pH-sensitive nanoparticle drug delivery systems were designed for the encapsulation of ETB. Methods Poly(acrylic acid)-cystamine-oleic acid (PAA-ss-OA) was synthesized. PAA-ss-OA-modified ETB-loade...
