We determine here the functional integrity of auxiliary livers in containers fashioned from the small intestine. Liver microfragments from dipeptidyl peptidase 4 (DPP4)-deficient rats were transplanted into syngeneic normal animals with isolated intestinal segments characterized by mucosal denudation but intact vascular supply. Transplanted liver fragments(More)
This study evaluated the potential of vascularized small intestinal segments for pancreatic islet transplantation. Islets isolated from Lewis rats were transplanted into diabetic syngeneic recipients. Segments of small intestine were prepared by denudation of the mucosal layer prior to implantation of pancreatic islets into the segments. Animal groups were(More)
BACKGROUND Development of an auxiliary liver is of interest for treating several conditions. To examine whether an isolated intestinal segment will support development of a heterotopic auxiliary liver, we studied the fate of liver microfragments in rats. METHODS Small intestinal segments with intact circulation were created, and the small intestinal(More)
BACKGROUND Transplanting pancreatic islets is of significant interest for type 1 diabetes mellitus. After intraportal injection of islets, inferior engraftment and eventual loss of transplanted islets constitute major limitations. Therefore, alternative approaches will be helpful. Here, we evaluated in animals whether an isolated venous sac would support(More)
Introduction. A total of 18 patients, with complete motor deficits and paraplegia caused by thoracic and lumbar spine trauma without muscle atrophy or psychiatric problems, were included into this study. Materials and Methods. The bone marrow was aspirated from the anterior iliac crest under local anesthesia and the mononuclear fraction was isolated by(More)
Transplantation of mature islets into portal vein has been most effective thus far, although attrition of transplanted islets constitutes a major limitation, and alternative approaches are required. We analyzed the mechanisms by which islets engrafted, vascularized and functioned over the long term in the small intestinal submucosa. To determine(More)
The purpose of our study was to reveal the possibility of cervical-to-petrous carotid artery in situ bypass with maximum preservation of cranial nerves. Four human cadavers prepared in formalin were investigated. Eight surgical approaches were used (bilateral exposure on each cadaver). The skin incision started from the level of the temporomandibular joint.(More)
This study was conducted to evaluate the usefulness of decellularized and lyophilized extracellular matrix, which was acquired from human amniotic membrane, for surgical closure of the mucogingival defects. Preliminarily, to create a gingival recession defect, silk ligature was applied on the gingival part of the upper incisor in the first (experimental)(More)
BACKGROUND AND OBJECTIVES Squamous cell carcinoma is the most common pathological type among the cancers of the larynx. Standard treatment for squamous cell carcinoma of the larynx is the combination of chemotherapy, radiotherapy, and laryngectomy. Pharyngocutaneous fistula is a common complication of laryngectomy. We hypothesized that decellularized and(More)
The aim of this review is to summarize recent developments in research on the characteristics of bone marrow-derived mesenchymal stem cell plasticity. Stem cells are uncommitted entities capable of both self-renewal and differentiation into multiple cell lineages. In general, there are certain types of stem cell populations that are identified from(More)
