Radical prostatectomy continues to play a central role in the management of localized prostate cancer. The majority of patients diagnosed with prostate cancer will undergo radical prostatectomy. A decrease in the morbidity of this surgical procedure has been accomplished through an improved understanding of pelvic anatomy and a greater understanding of the natural history of prostate cancer. Re...

The essential catalytic radical of Class-I ribonucleotide reductase is generated and delivered by protein R2, carrying a dinuclear metal cofactor. A new R2 subclass, R2c, prototyped by the Chlamydia trachomatis protein was recently discovered. This protein carries an oxygen-activating heterodinuclear Mn(II)/Fe(II) metal cofactor and generates a radical-equivalent Mn(IV)/Fe(III) oxidation state ...

Background & Aim: Medicinal plants can be a good replacement for common cancer treatment including chemotherapy, radiation therapy and surgery because they don’t have many side effects. The aim of this study was to investigate the effect of temperature on the free radical scavenging in the presence of medicinal plants. Experimental: For determination of free radical scavenging activity was use...

Let  be a commutative ring and  be a unitary  module. We define a semi prime sub module of a module and consider various properties of it. Also we define semi-radical of a sub module of a module and give a number of its properties. We define modules which satisfy the semi-radical formula and present the existence of such a module.

During the last years there has been a high interest in the development of new purelyorganic single-component conductors. Very recently, we have reported a new neutral radical conductor based on the perchlorotriphenylmethyl (PTM) radical moiety linked to a monopyrrolotetrathiafulvalene (MPTTF) unit by a π-conjugated bridge (1). Interestingly, this system behaves as a semiconductor with high con...

Background: Free radicals and reactive oxygen species(ROS) are the most important factors in formation of oxidative stress reaction. Now, radical damage has been suggested to contribute to a wide variety of diseases such as Alzheimer, atherosclerosis and cancer. Transition metal ions in the presence of the various biomolecules produce these active compounds. The aim of this study is introducing...

Double-strand breaks are widely accepted to be the most toxic form of DNA damage. Molecules that produce double-strand breaks via a single chemical event are typically very cytotoxic and far less common than those that form single-strand breaks. It was recently reported that a commonly formed C4'-radical produces double-strand breaks under aerobic conditions. Experiments described herein indica...

in order to optimization of protein hydrolysis condition (including enzyme to substrate ratio (e/s), temperature and time) for achieving the highest antioxidant activity, the green tiger prawn (p. semisulcatus) mince was tested via commercial protease (alcalase® 2.4l) based on the response surface designed method in 18 treatments and then dried to obtain powder in freeze dryer. the antioxidant ...
