The effect of 4-nitroquinoline 1-oxide on the cell-mediated immune response was tested in C57BL/6 female mice. The carcinogen was administered s.c. either 30 days before or just prior to grafting the female recipients with C57BL/6 male skin. Skin graft survival times were noticeably prolonged in mice that received the carcinogen 30 days before grafting. Administration of 4-nitroquinoline 1-oxid...

It becomes obvious that fat tissue is not just storage of excess carbohydrate. It is a regenerative complex supporting from the skin surface to deeper organs comprising adult stem cells as well as high energy resource related with tissue repair and regeneration. Fat grafting technique, which has been performed for more than hundred years, is utilized to improve defects of facial contour, fat at...

Macroporous polyacrylamide-grafted-chitosan scaffolds for neural tissue engineering were fabricated with varied synthetic and viscosity profiles. A novel approach and mechanism was utilized for polyacrylamide grafting onto chitosan using potassium persulfate (KPS) mediated degradation of both polymers under a thermally controlled environment. Commercially available high molecular mass polyacryl...

abstract background and objectives: patients are oriented towards spirituality after coronary artery bypass grafting (cabg). the aim of this study was to explore the patients’ spiritual experiences after cabg. methods: this qualitative study was conducted using hermeneutic phenomenology. 11 participants (7 males and 4 females) were interviewed in tehran heart center hospital in 2013 using maxim...

Protein adsorption and reversible cell attachment are investigated as a function of the grafting density of poly( Nisopropyl acrylamide) (PNIPAM) brushes. Prior studies demonstrated that the thermally driven collapse of grafted PNIPAM above the lower critical solution temperature of 32 ° C is not required for protein adsorption. Here, the dependence of reversible, proteinmediated cell adhesion ...

BACKGROUND Since spermatogonial stem cell transplantation (SSCT) and testicular tissue grafting (TTG) may have important clinical applications, the safety of these promising techniques has to be proved. This study was designed to characterize epigenetic modifications in prepubertal and adult mouse germ cells and to study these epigenetic mechanisms after SSCT and TTG. METHODS Testicular cell ...

BACKGROUND Cell-assisted lipotransfer is a novel technique for fat grafting. This study aimed to investigate the clinical efficacy of cell-assisted lipotransfer technology compared with conventional fat grafting. METHODS According to PRISMA guidelines, related articles in PubMed, Embase and Cochrane library were systematically searched. Studies focusing on fat survival rate and/or patient sat...
