BACKGROUND: The apoptosis of mature adipocytes after fat grafting can result in chronic inflammation, absorption, and fibrosis, leading to unpredictable outcomes. Selective elimination of mature adipocytes may result in better outcomes and a different underlying retention mode. We previously developed a mature-adipocyte-free product, SVF-gel, derived from lipoaspirate, which eliminates adipocytes while preserving the stromal vascular fraction. This study investigated the retention and regeneration mode of SVF-gel grafting...

INTRODUCTION: In live donor liver transplantation (LDLT) portal flush only of the graft is done on the bench. There is no data on antegrade arterial flush along with portal flush of the graft. METHODS: Consecutive patients undergoing elective right lobe LDLT were block-randomized to receive either portal flush only or both portal and antegrade arterial flush. The primary objectives were safety, rate of early allograft dysfunction (EAD), and impact on vascular and biliary complications RESULTS: After randomization there were 40 patients in each group...

We evaluated the effect of resveratrol (RSV) on graft survival after islet transplantation (ITx) in diabetic mice. Isolated islets from Balb/c mice (200 IEQ) were transplanted under the kidney capsule of diabetic Balb/c mice. Vehicle or RSV (200 mg/kg/day, orally) was given for 14 days after ITx. Two more control groups [STZ-treated (No-ITx-Control) and STZ+RSV-treated (No-ITx-RSV) mice without ITx] were added. Glucose tolerance tests (GTT) was performed at 14 days after ITx. In vitro, isolated islets pretreated with vehicle or RSV (1 μM) were incubated in a hypoxic chamber (O2 1%, 1hr)...

Angiotensin II type 1 receptor (AT1R) antibody, a non-HLA antibody, has been found to have a detrimental effect on kidney allografts. Similarly to HLA antibodies, recipients who have AT1R antibodies are at risk for allograft rejection and poor long-term graft outcome. Besides mediating allograft rejections via direct effects on endothelial and vascular smooth muscle without complement activation, AT1R antibodies may lead to accelerated hypertension via the renin-angiotensin pathway. There has been no definite level of AT1R antibody that predicts allograft rejection...

A 67-year-old man who presented with a bloody stool was diagnosed with ascending colon cancer. He had previously experienced thoracic and abdominal aortic dissections, which were treated with thoracic and abdominal aortic grafts and superior mesenteric artery revascularization. We performed a laparoscopic right hemicolectomy with a D3 lymph node dissection. During the laparotomy, we identified the superior mesenteric artery and an enlarged anterior superior pancreaticoduodenal artery. Injury to the latter artery could lead to severe ischemia in multiple organs; therefore, it was crucial to identify the primary feeding artery and vascular anatomy before and during surgery...

The endothelial glycocalyx (EG), a sugar-rich layer that lines the luminal surface of blood vessels, is an important constituent of the vascular system. Although the chemical composition of the EG is fairly well known, there is no consensus regarding its ultrastructure. While previous experiments probed the properties of the layer at the continuum level, they did not provide sufficient insight into its molecular organisation. In this work, we investigate the EG mechanics using two simple brush and bush-like simulation models, and use these models to describe its molecular structure and elastic response to indentation...

Mesenchymal stem cell therapy is a promising treatment for perianal Crohn's fistulas refractory to conventional therapy, which are an extremely morbid complication and a true therapeutic challenge. Autologous adipose-derived stromal vascular fraction (ADSVF) is an easily accessible source of cells with angiogenic, anti-inflammatory, immunomodulatory, and regenerative properties. Here, we describe a case involving a patient with severe perianal Crohn's fistulas refractory to the best medical and surgical practices who received local treatment with ADSVF and microfat...

The Lando® dermal scaffold is a newly developed, tissue-engineered dermal scaffold material. This study sought to observe its vascularization in an acute full-thickness skin-defect porcine model. There were eight Tibetan pigs in this research. Six 5 × 5 cm full-thickness skin-defect wounds were prepared on the dorsal area of each pig, which were divided into two groups. The experimental group wounds were covered by Lando® dermal scaffolds, while the other received Vaseline gauzes as blank control. At day 3, 7, 14 and 21 after injury, the general condition of wounds was observed, and wound specimens were obtained for HE staining, Masson staining and the expression of CD31, α-SMA and VEGF, which were examined by immunohistochemistry...

Background: Gastrointestinal acute graft-versus-host disease (GI aGVHD) is a lethal complication following allogeneic hematopoietic stem cell transplantation (HSCT). However, it is still very difficult to make a diagnosis of GI aGVHD in practice. To date, no consensus plasma biomarker of GI aGVHD can be used to help make a diagnosis. Here, we attempted to identify GI aGVHD associated plasma proteins in murine model, which can help make a diagnosis of GI aGVHD. Methods: We used 8-plex isobaric tags for relative and absolute quantitation (8-plex iTRAQ) to screen out proteins in plasma samples taken from murine models before and after allogeneic HSCT...

The cornea is the most commonly transplanted tissue in the body. Corneal grafts in low-risk recipients enjoy high success rates, yet over 50% of high-risk grafts (with inflamed and vascularized host beds) are rejected. As our understanding of the cellular and molecular pathways that mediate rejection has deepened, a number of novel therapeutic strategies have been unveiled. This manuscript reviews therapeutic approaches to promote corneal transplant survival through targeting (1) corneal lymphangiogenesis and hemangiogenesis, (2) antigen presenting cells, (3) effector and regulatory T cells, and (4) mesenchymal stem cells...

Because of problems with vaginal meshes and high rate recurrences of native tissue repair, more and more surgeons treat pelvic organ prolapse performing laparoscopic sacrocolpopexy. This surgery requires skilled surgeons. The first step of sacrocolpopexy is the dissection of tissues in front of the sacral promontory to reach the anterior longitudinal ligament. Some complications can occur during this dissection and the attachment of the mesh. This place is dangerous for surgeons because of the proximity of vessels, nerves and ureters...
