Mesoporous silica coated SPIONs containing curcumin and silymarin intended for breast cancer therapy.

Introduction: Super-paramagnetic iron oxide nanoparticles (SPIONs) are known as promising theranostic nano-drug carriers with magnetic resonance imaging (MRI) properties. Applying the herbaceous components with cytotoxic effects as cargos can suggest a new approach in the field of cancer-therapy. In this study mesoporous silica coated SPIONs (mSiO2@SPIONs) containing curcumin (CUR) and silymarin (SIL) were prepared and evaluated on breast cancer cell line, MCF-7.

Effects of Ellagic Acid on Oxidative Stress Index, Inflammatory Markers and Quality of Life in Patients With Irritable Bowel Syndrome: Randomized Double-blind Clinical Trial.

Unlabelled: Irritable bowel syndrome (IBS) is a common disorder that affects the large intestine. Oxidative stress and inflammation play a major role in IBS. Considering the antioxidant properties of ellagic acid (EA), this study was designed to evaluate the effect of EA on oxidative stress index, inflammatory markers, and quality of life in patients with IBS.

Improving Effect of Ellagic Acid on Sleep Quality and Gastrointestinal Symptoms in Patient With Irritable Bowel Syndrome: Randomized Double-Blind Clinical Trial.

Background: The quality of sleep in people with irritable bowel syndrome (IBS) is reduced by increased oxidative stress and clinical problems. Assessing the effects of ellagic acid (EA) on sleep quality and gastrointestinal symptoms in patients with IBS was the aim of this study.

Methods: In this research that was conducted as a randomized, double-blind, placebo-controlled clinical trial, 44 patients with IBS were enlisted.

The Drug Release Kinetics and Anticancer Activity of the GO/PVA-Curcumin Nanostructures: The Effects of the Preparation Method and the GO Amount.

The Graphene Oxide (GO) incorporated polyvinyl alcohol/sodium alginate (PVA-SA) composites with curcumin were prepared by the solvent casting and electro-spinning techniques. The GO was incorporated into PVA-SA nano-fiber and film matrixes, and the performance of these nano-composites as drug carriers was investigated. The effects of production method (film or mat) and GO amount on the water absorption properties and delivery of curcumin behaviors were investigated.

Pegylated magnetic mesoporous silica nanoparticles decorated with AS1411 Aptamer as a targeting delivery system for cytotoxic agents.

Fulfilling the purpose of developing a NP with theragnostic capabilities, the current study describes the synthesis of an aptamer-functionalized PEG-coated SPION/mesoporous silica core-shell nanoparticle for concurrent cancer targeted therapy and magnetic resonance imaging. SPIONs were synthesized according to a thermal decomposition method and served as cores for SPION/mesoporous silica core/shell nanoparticles (MMSNs). Doxorubicin was then successfully loaded in MMSNs which were then coated with di-carboxylic acid functionalized polyethylene glycol (PEG-MMSNs).

Design and fabrication of dual-targeted delivery system based on gemcitabine-conjugated human serum albumin nanoparticles.

Dual-targeted drug delivery system has established their reputation as potent vehicles for cancer chemotherapies. Herein, gemcitabine (Gem) was conjugated to human serum albumin (HSA) via dithiodipropionic anhydride to fabricate Gem-HSA nanoparticles. It was hypothesized that this system can enhance the low stability of Gem and can improve its intracellular delivery.

Formulation and in vitro evaluation of curcumin-lactoferrin conjugated nanostructures for cancerous cells.

Curcumin, a natural polyphenol, exhibits anti-oxidant, anti-inflammatory, anti-neoplastic and chemopreventive properties. In fact, targeting of this natural anticancer agent has received a great deal of attention during the recent years. In this study, we proposed that curcumin conjugation with lactoferrin molecules may lead to a potential drug delivery system targeted toward cancerous cells through both active and passive targeting.

Formulation and evaluation of targeted nanoparticles for breast cancer theranostic system.

Theranostic polymeric NPs developed for both cancer diagnosis and cancer therapy. This multifunctional polymeric vehicle was prepared by a single emulsion evaporation method, using carboxyl-terminated PLGA. LHRH as a targeting moiety, was conjugated to the surface of polymeric carrier by applying polyethylene glycol.

Docetaxel-Chitosan nanoparticles for breast cancer treatment: cell viability and gene expression study.

Docetaxel acts through the inhibition of tubulin polymerization and reduction in the expression of BCL-2 gene. In this study, nanoparticles containing Docetaxel were prepared and their effects on the gene expression levels of BCL-2 and BAX genes were investigated. The drug was first conjugated to chitosan, and the nanoparticles were assembled in the presence of hyaluronic acid.

Protein corona hampers targeting potential of MUC1 aptamer functionalized SN-38 core-shell nanoparticles.

Nanoparticles have been considered to improve delivery and physicochemical characteristics of bioactive agents in recent years. In this study, a core-shell chitosan nanoparticulate system was prepared for the targeted delivery of SN-38. SN-38, an active metabolite of camptothecin, conjugated to hyaluronic acid (HA) was used as the shell of chitosan nanoparticles decorated with MUC1 aptamer.
