This paper provides an overview of how the surface properties of ferromagnetic nanoparticles dispersed in fluids is modified by natural and biocompatible polymers. Among common magnetic nanoparticles, magnetite (Fe3O4) and maghemite (g-Fe203) are popular candidates because of their biocompatibility. Natural polymeric coating materials are the most commonly used biocompatible magnetic nanopartic...
An ideal carrier that delivers small interfering RNA (siRNA) should be designed based on two criteria: cellular-mediated internalization and endosomal escape. Poly(histidine-arginine)6(H6R6) peptide was introduced into chitosan (CS) to create a new CS derivative for siRNA delivery, 6-polyarginine (R6) as cell-penetrating peptides facilitated nanoparticle cellular internalization has been proved...
Background: Heavy metals, even at low concentrations, are harmful to human health and environment. Cadmium as a heavy metal is highly toxic and can cause serious threat to living organisms. This research was designed to evaluate the adsorption potential of modified magnetic iron nanoparticles by 2-(5-bromo-2-pyridylazo)-5-diethylaminophenol ligand for the removal of cadmium ions from water solu...
the discharge of lead containing effluents into the environment and water bodies is harmful for the human, animals, aquatic flora and fauna. herein, a novel surface engineered magnetic nanoparticle for removing pb2+ ions was studied. after surface modification of the magnetite by 3-amino-propyltriethoxysilane (aptes) magnetic nanoparticles with covalently linked porphyrins were synthesized. two...
in the present investigation, a novel adsorbent, ionic liquid modified magnetic nanoparticles (il-fe3o4), was successfully synthesized and characterized by ft-ir spectroscopy, thermogravimetric analysis (tga), xrd analysis, scanning electron microscopy (sem) and theory of brunauer, emmett, and teller (bet) for removal of reactive orange 122 (ro-122) from aqueous solutions. the effects of variou...
BACKGROUND The purpose of this study was to develop intraperitoneal hyperthermic therapy based on magnetic fluid hyperthermia, nanoparticle-wrapped cisplatin chemotherapy, and magnetic particles of albumin. In addition, to combine the multiple-killing effects of hyperthermal targeting therapy, chemotherapy, and radiotherapy, the albumin-nanoparticle surfaces were linked with radionuclide (188)R...
نیتریک اکساید از l-arginine و توسط ایزوآنزیم های مختلف nitric oxide synthase و در بافت های مختلف تولید میشود.مطالعات مختلفی مبنی بر نقش نیتریک اکساید در سیستم عصبی و در التهاب و سپسیس انجام شده است.در این مطالعه به بررسی نقش سیستم نیتررژیک در تغییرات آستانه تشنجات کلونیک ناشی از تزریق وریدی پنتیلن تترازول در موش های سوری نر که با متد clp به سیس مبتلا شده اند پرداخته شده است.از مدل cecal ligatio...
cyanide is one of the major environmental pollutants in industrial wastewater. entrance of it to existence environmental contains very health hazardous. the cyanide can be removed from aqueous solutions in many ways, but most of these methods are expensive. in the present study, novel magnetic nanoparticle modified with a polydentate ligand is used to remove cyanide. the procedure is efficient ...
در سیستم nitric-oxide از l-arginine به عنوان پروکورسور و از l-name به عنوان مهارکننده می توان نام برد. پژوهشگران نشان داده اند که تزریق نیتروپروساید سدبم (در محیطی بیولوژیکی سریعا به no تبدیل می شود) در محیط کشت در رشد و تکامل اختلال می نماید و وفتی مهارکننده سیستم no به آن محیط اضافه می شود، نه تنها از میزان ناهنجاری زائی کاسته نمی شود، بلکه خود ایجاد ناهنجاری های متفاوت می کند. (28) با توجه ب...
