The aim of the present work was to prepare and characterize biopolymer nanocarriers and evaluate their suitability in possible oral delivery of insulin. The egg albumin biopolymer was used to prepare nanoparticles which were further characterized by Fourier transformed Infrared spectroscopy (FTIR), transmission electron microscopy (TEM), scanning electron microscopy (SEM), zeta potential, Dynam...

Abstract With the long-term goal of developing an ultra-sensitive microcantilever-based biosensor for versatile biomarker detection, new controlled bioreceptor-analytes systems are being explored to overcome disadvantages conventional ones. Gold (Au) microwires have been used as a probe tolerance problem that occurs in response changes environmental conditions. However, cytotoxicity Au is still...

Abstract This paper aimed to investigate the selected physicochemical and biological properties of titanium dioxide thin films deposited by atomic layer deposition on 316LVM stainless steel dedicated for cardiovascular implants. The main challenge in surface modification these implants is complexity processes taking place circulatory system. was carried out a number cycles 500 temperature 200 °...

The synthesis by transmetallation and in-depth characterisation IR spectroscopy of five half-sandwich ruthenium osmium dithiocarbamato isonipecotamide glycoconjugate complexes are presented herein. evaluation their in vitro cytotoxicity the zinc precursors’ towards ovarian cancer (A2780 A2780cisR) normal prostate (PNT2) cells is reported. While compounds rather limited, some selectivity observed.

background: based on recent studies, there are controversial reports on the ca-pacity of tissue cyst forming of toxoplasma gondii rh strain. in this study, the capac-ity was evaluated by in vivo and in vitro experiments. methods : rh strain was subcutaneously inoculated to ten wistar rats. after one month, their blood, brain, tongue and diaphragm were collected and evaluated by mat, pcr, pathol...

The effects of different concentrations of the hydroalcoholic extract of dried powdered leaves of Cichorium intybus L., on CCl4-induced hepatotoxicity in vivo in rats and CCl4-induced cytotoxicity in isolated rat hepatocytes were investigated. Rats received different concentrations of the extract by i.p. injection for 3 consecutive days before the injection of (3ml/kg) CCl4 (i.p.). Twenty four ...

Cultured spleen cells from normal or MOPC-315 tumor-bearing BALB/c mice that were pretreated in vivo with Bacillus Calmette-Guérin (BCG) exhibited in vitro cytotoxicity against MOPC-315 plasmacytoma. In vitro education of BALB/c spleen cells from normal or tumor-bearing mice by cocultivation with mitomycin C-treated MOPC-315 stimulator cells also resulted in antitumor cytotoxicity. The combinat...

this study was conducted to determine the chemical composition, digestibility, degradability and nutritive value of madder, rubia tinctorum l.  and alfalfa medicago sativa. using in vitro and in situ measurements. the mean values for om, cp, ndf, adf and ee were 892.5, 172.0, 306.5, 219.4 and 16.0 g/kg dm for madder hay, and 921.3, 141.4, 482.0, 361.1 and 6.50 g/kg dm for alfalfa hay, respectiv...
