In this work, a review about the applicability of eutectic solvents, mainly deep solvents (DES) and natural (NADES), for extraction bioactive compounds from products has been carried out. These alternative have shown not only to high yields but also be environmentally friendly, exhibiting very low or almost no toxicity, compared conventional organic solvents. The last trends main methods that m...

objective(s):according to the prevalence of neoplastic diseases, there is a deep necessity for discovery of novel anticancer drugs in the field of medicinal chemistry. in the current study, a new series ofphenylthiazole derivatives(compounds 4a-4f) was synthesizedand theiranticancer activity was assessed in vitro. materials and methods:all synthesized derivatives were evaluated towards three hu...

b ackgro un d : the antimicrobial activity of silver nanoparticles has been investigated in medical fields in recent years, but there are few studies regarding its effect on oral microorganisms. the aim of the present study was to evaluate the in vitro antimicrobial and toxicity properties of nanosilver against two dental plaque microorganisms  and human gingival fibroblast (hgf) cell line. me ...

objective(s): the aim of this study was to determine cytotoxic effect of nanoliposomal form of lyophilized aqueous extract of ecballium elaterium fruit on gastric cell line (ags) using cell viability tests. methods: an aqueous extract of the fruits of ecballium elaterium was prepared. nanoliposomal form was also prepared by thin-film hydration method and stability size was determined by sem. th...

The corrosion resistance and biocompatibility of a novel Fe50Cr18Mo10C20Si2 metallic glass (Fe–MG), are studied by electrochemical measurements indirect contacting cytotoxicity assays for biomedical applications. In Hank’s solution, the Fe–MG shows better than SS316L, evidenced larger polarization in potentiodynamic impedance spectroscopy (EIS) tests, lower amounts released ions during immersio...

The CD33/CD3-bispecific T-cell engaging (BiTE) antibody construct, AMG 330, potently lyses CD33+ leukemic cells in vitro. Using specimens from 41 patients with acute myeloid leukemia (AML), we studied the factors that might contribute to clinical response or resistance. For this purpose, thawed aliquots of primary AML samples were immunophenotypically characterized and subjected to various dose...

Assessment of C(60) nanotoxicity requires a variety of strategies for dispersing it into biological systems. Our objective was to determine organic solvent/surfactant combinations suitable for this purpose. We used Escherichia coli (ATCC# 25254) to determine the cytotoxicity of C(60) in solvents at concentrations up to 100 ppm. In this preliminary study we hypothesized that C(60) toxicity is di...

In the recent years, the use of nanomaterials has increased exponentially. In spite of the extensive research in this field, some areas are not completely understood, one of them being nanosafety. Because of their size and shapes, these nanomaterials have the ability to be easily absorbed in the biological and the ecological systems and interfere with them by hampering smooth functioning. In th...
