New materials of emerging technological importance are single-walled carbon nanotubes (SWCNTs). Because SWCNTs will be used in commercial products in huge amounts, their effects on human health and the environment have been addressed in several studies. Inhalation studies in vivo and submerse applications in vitro have been described with diverging results. Why some indicate a strong cytotoxici...

Background and Objective: Free radicals cause many diseases in human and their neutralizing by antioxidants reduces risk of cancers. Salvia Officinalis from Lamiaceae family is one of the valuable plants in traditional medicine. The present study aimed to evaluate the antioxidative and cytotoxic properties of ethanolic extract of the aerial parts of this plant on human prostate and cervical can...

The aim of this investigation was to design and develop nanoemulsions as novel delivery systems for rapamycin. Phase behavior of quaternary systems composed of Traicetin (as oil), various surfactants and co-surfactants and water at different surfactant/co-surfactant weight ratios were investigated by the construction of phase diagrams. Formulations were taken from the o/w NE region of the phase...

Background & Aim:Cervical cancer is the most common   female genital cancer and the second most common cancer in women in the   world. Since the herbal ingredients have been used for centuries to treat   cancer, purpose of the present study was to determine the cytotoxic   effect of hydroalcoholic extract from Satureja bachtiarica Bungeon   Hela cancer cells line. ...

The functionalized graphene/montmorillonite (FG/MTT) nanosheet was synthesized through chemical bonding by a simple, green method, which had remarkable dispersion stability in oil and its lubricating performance evaluated four-ball tribometer. test results showed that FG/MTT preeminent lubricant property when the concentration 0.4 mg/ml. Compared with bare sample, average friction coefficient (...

The MTT (3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyltetrazolium bromide) assay is a classical method for screening cytotoxic anti-cancer agents. Candidate drugs from the MTT assay need in vivo models to test their efficiency and to assess the absorption, distribution, metabolism, excretion, and toxicity of the drugs. An in vivo screening model could increase the rate of development of anti-cancer...

OBJECTIVE To examine the use of the term 'metric' in health and social sciences' literature, focusing on the interval scale implication of the term in Modern Test Theory (MTT). MATERIALS AND METHODS A systematic search and review on MTT studies including 'metric' or 'interval scale' was performed in the health and social sciences literature. The search was restricted to 2001-2005 and 2011-201...
