At this short review, different chemical production of 3D graphene biocatalysts and developing of its characters by new substituted for using in enzymatic fuel cells are investigated. Also, the current ways of production of 3D Graphene Biocatalysts, different types of substitutes, the best methods for having the highest efficiency, the physical, chemical and biological characters of new biocata...
nitric oxide (no) is a simple ubiquitous signaling molecule and plays important roles in almost every biological system. recent evidences suggest that no may act as an endocrine molecule. the aim of this review is considering available literature on endocrine roles of no and/or its metabolites, i.e. nitrite and nitrate. existing data suggest the idea that no is a hormone that after production i...
application of nanotechnology in medicinal and biological fields has attracted a great interest in the recent yeras. in this paper the cell membrane leakage induced by iron nanoparticles (fe-np) against pc12 cell line which is known as a model of nervous system cell line was investigated by the lactate dehydrogenase (ldh) test. therefore, pc12 cells were incubated with different concentration o...
objective: because of the therapeutic application of stem cells (scs), isolation and characterization of different types of scs, especially mesenchymal stem cells (mscs), have gained considerable attention in recent studies. adipose tissue is an abundant and accessible source of mscs which can be used for tissue engineering and in particular for treatment of musculoskeletal disorders. this stud...
multiple sclerosis is an inflammatory disease of the central nervous system in which t cells experience a second phase of activation, which ultimately leads to axonal demyelination and neurological disability. the recent advances in stem cell therapies may serve as potential treatments for neurological disorders. there are broad types of stem cells such as neural, embryonic, mesenchymal and hem...
objective: the number of new cancer cases with considerable mortality is increasing worldwide. since the inability of current therapies in treatment of patients and prevention the progress of tumors with fewer side effects, implementation of new methods is needed. gene therapy has widespread systemic cytotoxic effects against tumor cells. rotavirus nsp4 has been shown to elicit extensive cytoto...
hepatitis b virus (hbv) is considered as a global health concern and hepatitis b surface antigen (hbsag) is the most immunogenic protein of hbv. the purpose of this study was to evaluate the expression of hbsag on the cell surface of human embryonic kidney cell line (hek293t). after transformation of expression vector pcdna/hbsag to e.coli top10f’, plasmid was extracted and digested with bglii....
background: natural medicines have been recently considered more reasonable for human use most notably due to their safety and tolerance. hesa-a is a marine-originated herbal medicine with a variety of healing effects. however, its exact biological mechanism is not clear. the pre-sent study aimed at the evaluation of the hesa-a antioxidant effect. methods: chinese hamster ovary (cho) and human ...
Cancerous human fibrosarcoma cells undergo collective migration at the edge of their colony by combining mesoscale self-organization and intrinsic handedness, showing how physical interactions alone can lead to biological functionality.
Lipid membranes envelope live cells and mediate vital biological functions through regulated spatiotemporal dynamics. This review highlights the role of neutron scattering, among other approaches, in uncovering dynamic properties lipid membranes.
