In recent years, Hyperthermia has been used as an emerging technique for cancer treatment, especially for localized tumors. One of the promising cancer treatment approaches is magnetic nanoparticle (MNPs) Hyperthermia. In this theoretical work, the temperature distribution of a common tumor over the different sizes of Fe3O4 magnetic nanoparticles, namely 25, 50, 100, and 200 nm, was stud...

The aim of this research is to elucidate the size effect of magnetic nanoparticles on the resultant magneto-dielectric properties of polymer nanocomposites at radio frequencies. The block copolymer of [styrene-b-ethylene/butylene-b-styrene] (SEBS) was utilized as a matrix for the templating of magnetic nanoparticles. Surfactant-modified iron oxide (Fe3O4) nanoparticles of various sizes were suc...

Nitric oxide (NO) has been implicated in large number of pathologies ad in normal physiological function of the brain. The aim of this study was to recognize the effect of Nitro-L-Arginine Methyl Ester mHC1 (NAME) and L-Arginine Ethyl Ester.HC1 (ARGININE) on reactivity of the central DA Dg receptor to agonist (Quinpirole) in rats. For this reason we have been used specific behavioural procedure...

background: role of nitric oxide (no) on expression of morphine conditioning using a solely classic task has been proposed previously. in this work, the involvement of no on the expression of opioid-induced conditioning in the task paired with an injection of naloxone was investigated. methods: conditioning was established in adult male wistar rats (weighing 200-250 g) using an unbiased procedu...

objective: tthe objective of this study was to assess the efficacy and safety of sx (combination of yohimbine and l-arginine) in the treatment of erectile dysfunction (ed) methods: this trial was a 4-week, double blind study of parallel groups of patients with mild to moderate ed. forty married male patients with ed of mild-to-moderate severity were screened for the study entry;among them, thos...

Among a variety of hyperthermia methods, magnetic nanoparticle hyperthermia is a highly promising approach for its confined heating within the tumour. In this study we perform in vivo animal experiments on implanted prostatic tumours in mice to measure temperature distribution in the tumour during magnetic nanoparticle hyperthermia. Temperature elevations are induced by a commercially available...

We have developed a novel, highly sensitive, biosensing system for detecting methicillin-resistant Staphylococcus aureus (MRSA). The system employs gold nanoparticles (AuNPs), magnetic nanoparticles (mNPs), and an electrochemical detection method. We have designed and synthesized ferrocene- and single-stranded DNA-conjugated nanoparticles that hybridize to MRSA DNA. Hybridized complexes are eas...

An impedimetric biosensor based on PEGylated arginine functionalized magnetic nanoparticles for early detection of cervical cancer is reported. The cervical cancer cells could be selectively and sensitively detected down to 10 cells mL(-1) on the modified electrode, which is promising for advancement in clinical diagnosis and monitoring of tumors.
