In this study, biofunctionalized globular or oval shaped silver nanoparticles were obtained by using aqueous extract of lemon peel (Citrus limon) via microwave-accelerated heating system. While UV−visible spectroscopy, FTIR and XRD analyses applied to recognize the formation nano-silver, TEM Zeta analysis employed reveal their morphological features. UV–vis spectrum fabricated AgNPs indicated i...

Bioincompatibility of conventional glucose-based peritoneal dialysis fluids (PDF) has been partially attributed to the presence of glucose degradation products (GDP) generated during heat sterilization of PDF. Most previous studies on GDP toxicity were performed on animal and/or transformed cell lines, and the impact of GDP on peritoneal cells remains obscure. The short-term effects of six iden...

The growth of Rickettsia prowazekii Madrid E was monitored in mouse L929 cells subcultured for several weeks in the presence of gamma interferon (IFN-gamma) to determine whether the rickettsiae would be eliminated from or would persist in these cultures. R. prowazekii exhibited two distinct patterns in these IFN-gamma-treated cultures. In some cases, IFN-gamma-induced inhibition of rickettsial ...

There are a number of reports of the plasma membrane transport of Ca2+ in biological systems being enhanced by low frequency electromagnetic fields (EMF), including reports that the enhancement involves a resonance-type response at the cyclotron frequency for Ca2+ ions for geomagnetic values of the magnetic field. Using the fluorescent probe fura2, we find no evidence for changes in cytosolic c...

Commercially available calf serum did not supply the cultured murine fibroblast cell line L929 with amounts of selenium and alpha-tocopherol sufficient to protect against peroxide damage. Supplementation of the culture medium with 30 microM alpha-tocopherol or 50 nM sodium selenite led to a substantial increase of cellular alpha-tocopherol concentrations from 18 +/- 3.0 to 3179 +/- 93.0 pmol/10...

Low back pain is one of the most reported medical conditions associated to intervertebral disc (IVD) degeneration. Nucleus pulposus (NP) is often regarded as the structure where IVD degeneration begins. Gellan gum (GG)-based hydrogels for acellular and cellular tissue engineering strategies have been developed for finding applications as NP substitutes. The innovative strategy is based on the r...

Objective(s): Polyethylenimine (PEI) is one of the most widely used polymers in gene delivery. The aim of this study was to modify PEI by replacing some of its primary amines with Brevinin 2R (BR-2R) peptide in order to increase the efficiency of gene delivery.Materials and Methods: Polyethylenimine was modified by BR-2R peptide by two d...
