the aim of our work was to compare cytotoxic and membrane-damaging effects of o. majorana l. essential oil and linalool on hep g2 and to investigate their possible protective (antioxidant) effects against h2o2 induced membrane damage. the oils were investigated by gc and gc-ms and antioxidant activity was evaluated by dpph and -carotene–linoleic acid assays. assessment of cell viability was ma...

aquaporins are integral membrane proteins from a larger family of major intrinsic proteins that formpores in the membrane of biological cells. aquaporins form tetramers in the cell membrane with eachmonomer acting as a water channel.in this research, the aqp4 tetramer was modeled from its pdbstructure file, then, we have performed the intraction of aquaporin4 in different temperatures (298k,300...

the past decade has witnessed the revival of amniotic membrane transplantation (amt) in ophthalmology. the importance of amt is due to its ability to reduce scarring and inflammation and to enhance wound healing and epithelialization, and also its anti-microbial properties. amniotic membrane has recently been used as a substrate for culturing limbal stem cells for transplantation. it has been u...

Objective(s):One of the major challenges in the field of vaccine design is choosing immunogenic antigens which can induce a proper immune response against complex targets like malignant cells or recondite diseases caused by protozoan parasites such as leishmaniasis. The aim of this study was to find a way to construct artificial liposome-based cells containing fragments of target’s cell membran...

Abstract Intensive development of systemic biology involves intensification such branches as proteomics and lipidomics, which are valid for plants. This trend is obvious due to the rapidly growing number publications on proteomes lipidomes plant cells, tissues, whole organs. Particulars nuclei, mitochondria, chloroplasts have been rather well detailed in this regard. However, these data scarce ...

3450 bovine from different breeds and ages were clinically examined for the presence of arthritis. 120 cases showed macroscopic evidences of arthritis. Mycoplasma spp were isolated from synovial fluid of 21 affected animals. In addition to Mycoplasma spp. Arcanobacterium pyogenes and Staphylococcus epidermidis were isolated from 2 cases. The synovial fluid was markedly increased, straw color, t...

Although proton-exchange membrane fuel cells (PEMFC) are considered as a safe and clean energy technology, aging phenomena of the membrane-electrode assembly (MEA), more particularly membrane, still restrict PEMFC lifetime. In this paper, ex-situ accelerated chemical degradation – via Fenton's reagents exposure reinforced Nafion™ XL is performed in order to investigate impact on structure prope...

Objective(s): The purpose of this study was to investigate cytotoxicity and membrane toxicity effects induced by Mesobuthus eupeus venom (MEV) on the HT-29 cell line. Materials and Methods: To determine the in vitro cytotoxicity via MTT assays, HT-29 (as cancer cell line) and Hek-293T (as normal cell) were treated through different conce...
