human adipose tissue represents an abundant, practical and appealing source of donor tissue for autologous cell replacement. recent findings have shown that stem cells within the stromalvascular fraction of adipose tissue display a multilineage developmental potential. adipose tissue-derived stem cells can be differentiated towards adipogenic, osteogenic, chondrogenic,myogenic and neurogenic li...

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 and aims. furcally-involved teeth present unique challenges to the success of periodontal therapy and influence treatment outcomes. this study aimed to assess to compare use of adm and connective tissue membrane in class ii furcation defect regeneration. materials and methods. 10 patient with 2 bilaterally class ii furcation defects in first and/or second maxilla or man-dibular molar...

context periodontal plastic surgery can help people improve their lives by addressing aesthetic parameters of their smile. much of what comprises a beautiful and appealing smile is influenced by emotion and personality; however, many structural elements of a smile can be improved through surgical intervention. evidence acquisition the end result often lends significant support to people who wis...

background: since the treatments of long tracheal leisions are associated with some limitations, tissue enginered trachea is considered as an alternative option. this study aimed at preparing a composite scaffold, based on natural and synthetic materials for tracheal tissue engineering. methods: nine chitosan silk-based scaffolds were fabricated using three freezing rates (0.5, 1, and 2°c/min) ...

abstract this experiment was conducted for optimizing a suitable medium for callus induction, regeneration and rooting of anthurium. leaf and petiol explants of antadra and casino varieties were used for callus production. ms medium was supplied with growth regulators (naa, ba, kin and iba). a complete randomized design with 3 replication was used in this expriment. result indicates that variet...

background and aims. connective tissue grafts with and without periosteum is used in regenerative treatments of bone and has demonstrated successful outcomes in previous investigations. the aim of present study was to evaluate the effectiveness of connective tissue graft with and without periosteum in regeneration of intrabony defects. materials and methods. in this single-blind randomized spli...

background nicotinamide (na), the active form of vitamin-b3, is hypothesized to have positive effects on the process of wound healing; it has anti-inflammatory, antioxidant, and immunomodulatory properties, as well as an epithelization inducing action. objectives in the present study, we aimed to determine the effects of topical administration of na on skin wounds, based on histomorphometrical ...

who recommends artemisinin-based combination therapies (acts) as the most effective choice to treat malaria. for developing transgenic plants with high accumulation of artemisinin (by introducing genes encoding enzymes which regulate the biosynthetic pathway of artemisinin), an efficient protocol for tissue culture and plant regeneration is necessary. in the present study, leaf explants of arte...
