The construction of a smooth muscle layer for blood vessel through electrospinning method plays a key role in vascular tissue engineering. However, smooth muscle cells (SMCs) penetration into the electrospun graft to form a smooth muscle layer is limited due to the dense packing of fibers and lack of inducing factors. In this paper, silk fibroin/poly (L-lactide-ε-caplacton) (SF/PLLA-CL) vascula...

The mechanical behavior of aortic stent grafts plays an important role in the success of endovascular surgery for aneurysms. In this study, finite element analysis was carried out to simulate the expansion of five marketed stent graft iliac limbs and to evaluate quantitatively their mechanical performances. The deployment was modeled in a simplified manner according to the following steps: (i) ...

BACKGROUND Burns are among the most devastating forms of injury. Nowadays the standard treatment for deep partial thickness and full-thickness burn is early excision and grafting, but this technique is not always feasible; and this leads to chronicity and microbial colonization of burn wounds. Interesting properties of human amniotic membrane made us use it in management of chronic infected bur...

OBJECTIVE To compare the 3-year incidence of de novo ocular hypertension (OHT) after Descemet stripping automated endothelial keratoplasty (DSAEK) and penetrating keratoplasty (PK). For DSAEK, to evaluate predictors for OHT and 2-year outcomes after OHT development. METHODS This was a review of the prospective Singapore Corneal Transplant Study at a single tertiary referral center. Consecutiv...

Several researches have shown that negative-pressure wound dressings can secure split-thickness skin grafts and improve graft survival. However, in anatomically difficult body regions such as the perineum it is questionable whether these dressings have similar beneficial effects. In this study, we evaluated the effects of negative-pressure wound dressings on split-thickness skin grafts in the p...

Abstract Background This study aims to compare the graft uptake rate and hearing improvement of fat versus inlay butterfly tragal cartilage in repair perforations chronic otitis media mucosal adults. In this retrospective study, twenty-eight patients were included with small dry anteroinferior tympanic membrane (less than 1/3 membrane). The age range was 18 44 years old. Myringoplasty done unde...

The success of coronary artery bypass grafting (CABG) surgery mainly depends on the pa‐ tency of graft vessels. The predominant mechanism of early graft failure after coronary sur‐ gery is associated with antiplatelet treatment using drungs such as acetylsalicylic acid (ASA). Prevention using oral ASA in the early postoperative phase in patients with vascular disease is associated with a 25% to...

Technical and secure information on the production of quality atemoya seedlings (Annona squamosa L. x Annona cherimola Mill.) are paramount importance due to growing interest in this crop. This study aimed assess formation propagated by grafting methods cultivars using araticum sylvatica) rootstocks. The experiment was carried out a screened environment at Western Paraná State University (Unioe...

Common carotid artery (CCA) pseudoaneurysms are rare and potentially lethal, and adequate treatment is warranted in order to prevent rupture or neurologic sequelae. The causes of CCA pseudoaneurysm include blunt or penetrating trauma, infection, and vasculitis, as well as iatrogenic and unknown causes. Previously, surgery was the standard treatment for pseudoaneurysm. However, endovascular surg...

The effect of HLA matching on cadaver kidney graft survival was analysed in over 9000 transplants. Matching for HLA-A and -B accounted for an improvement of 8% in the one-year survival rate, matching for HLA-DR for 10%, and matching for HLA-B + DR for 19%. The matching effect of the HLA-B and HLA-DR loci was additive. Patients without pre-transplant transfusions had lower graft survival rates t...
