Chitosan, Polyethylene Glycol and Polyvinyl Alcohol Modified MgFe2O4 Ferrite Magnetic Nanoparticles in Doxorubicin Delivery: A Comparative Study In Vitro

Surface Adsorption of Polyethylene Glycol and Polyvinyl Alcohol with Variable Molecular Weights on Zinc Oxide Nanoparticles

a comparative study of the relationship between self-, peer-, and teacher-assessments in productive skills

تمایل به ارزیابی جایگزین و تعویض آن با آزمون سنتی مداد و کاغذ در سالهای اخیر افزایش یافته است. اکثر زبان آموزان در کلاس های زبان از نمره نهایی که استاد تعیین میکند ناراضی اند. این تحقیق جهت بررسی ارزیابی در کلاس های زبان انگلیسی به هدف رضایتمندی زبان آموزان از نمره هایشان انجام گرفته است که در آن نمرات ارائه شده توسط سه گروه ارزیاب (ارزیابی خود دانشجو، همسالان واستاد) در مهارت های تولید (تکل...

Glycol chitosan nanoparticles as specialized cancer therapeutic vehicles: Sequential delivery of doxorubicin and Bcl-2 siRNA

Conventional chemotherapy is plagued with adverse side effects because cancer treatments are subject to numerous variations, most predominantly from drug resistance. Accordingly, multiple or multistage chemotherapeutic regimens are often performed, combining two or more drugs with orthogonal and possibly synergistic mechanisms. In this respect, glycol chitosan (GC)-based nanoparticles (CNPs) se...

Preparation of modified magnetic nanoparticles for in vitro delivery of ceftriaxone

In this research, a novel method is reported for the surface grafting of n-vinylcaprolactam as a thermosensitive agent and 3-allyloxy-1,2-propandiol with an affinity toward ceftriaxone onto modified magnetic nanoparticles by 3-mercaptopropyltrimethoxysilane. The grafted nanoparticles were characterized by Fourier Transform Infrared Spectroscopy, Elemental Analysis, and Vibrating Sample Magnetom...

Comparative Study of the Antitumor Activity of Free Doxorubicin and Polyethylene Glycol-coated Liposomal Doxorubicin in a Mouse Lymphoma Model1

Here, we investigate various factors affecting the therapeutic efficacy of free doxorubicin (Free-Dox) and polyethylene glycol (PEG)-coated (PEGylated) liposomal doxorubicm (referred to as Doxil) in the ascitic J6456 lymphoma model of BALB/c mice. Free drug and liposomal drug were affected differently by the tumor burden and route of treatment administration. A delay in start of treatment from ...
