Background Despite successful cloning of many mammalian species, the cloning efficiency is extremely low compared to that of IVF raising the possibility of the existence of epigenetic barrier preventing successful cloning. MaterialsAndMethods Using comparative transcriptome analysis comparing transcriptomes of IVF and SCNT embryos and that of donor cells, we identified epigenetic barrier and fi...

the aim of this study was to investigate the barrier properties of cellulose nanocrystals-pvananocomposites. nanocomposite films with different filler loading levels (3, 6, 9 and 12% by wt) weredeveloped by solvent casting method. the effect of cellulose nanocrystals on the barrier properties ofthe nanocomposites was studied. to this end, moisture absorption, water vapor permeability (wvp),oxyg...

one of the quranic concepts concerning the hereafter is the lofty barrier (araf) and their men regarding which the words of revelation of 46-49 in araf surah in the holy quran have pointed this concept. there are different viewpoints among commentators concerning what and where the lofty barrier is, and also who the men of the lofty barrier are. regarding this, different viewpoints have been ta...

in this paper, using a one-dimensional simulation model, the reforming process of sour gas, i.e. ch4, co2, and h2s, to the various charged particles and syngas in a dielectric barrier discharge (dbd) reactor is studied. an electric field is applied across the reactor radius, and thus a non-thermal plasma discharge is formed within the reactor. based on the space-time coupled finite element meth...

since nox family, one of the most important causes of air pollution, is the primary source of acid rains, ozone layer depletion, and breathing disorders, mitigation of these pollutants is now a global concern. in the off-gases of internal combustion engines running with oxygen excess, non-thermal plasmas (ntps) have an oxidative potential, which results in an effective conversion of no to no2. ...

cell based therapeutics is one of the most rapidly advancing medical fields, bringing together a range of fields including transplantation, tissue engineering and regeneration, biomaterials and stem cell biology. however, traditional cell-based therapeutics have many limitations, one of which is their harmful effects exhibited on healthy body cells due to their lack of specificity. nanomedicine...

context this article reviews the available evidence about the barrier membranes utilized in guided tissue regeneration process to prevent the migration of unfavorable cells to the wound area. evidence acquisition available evidence about membranes properties and their different uses were reviewed, and the results of clinical and animal studies and systematic reviews were gathered. results a lar...

background: caring is the essence of nursing. since care is influenced by cultural, economic, and social factors, various diverse barriers exist in the realization of care. the aim of the study was to clarify barriers to caring in emergency patients based on experiences of nurses and patients and their relatives. materials and methods: a qualitative design of content analysis was used to identi...

blood brain barrier (bbb) is a specialized non fenestrate barrier that formation by the endothelial cells and controls the transportation of the cells and molecules in to the brain. reducing in function of bbb is one of disruptions in neurological diseases like multiple sclerosis. endothelial progenitor cell (epc) help to the bbb to control the diapedesis of inflammatory cells & molecules in to...
