Candida parapsilosis is an opportunistic human fungal pathogen that poses a serious threat to low birth weight neonates, particularly at intensive care units. In premature infants, the distinct immune responses to Candida infections are not well understood. Although several in vivo models exist to study systemic candidiasis, only a few are available to investigate dissemination in newborns. In addition, the majority of related studies apply intraperitoneal infection rather than intravenous inoculation of murine infants that may be less efficient when studying systemic invasion...

INTRODUCTION: The supracricoid partial laryngectomy has been described for the treatment of T3 laryngeal glottic and supraglottic tumors as well as upfront and salvage surgery. Good oncological and functional outcomes are expected, while the post-operative rehabilitation can be quite difficult for the patient. Early and late complications can occur especially in salvage surgery. Neck dissection according to the T stage is often associated with the resection of the primary tumor. OBJECTIVE: To verify the feasibility of a minimally invasive procedure for supracricoid partial laryngectomy by adopting the lateral cervical approach...

Efforts to increase the dismal deceased renal transplantation (DRT): live renal transplantation (LRT) ratio in our country have gathered momentum recently, with governmental and non-governmental projects focussing on building public awareness and capacity-building, and appropriate legislation. Worldwide, efforts at increasing the number of organs from the deceased pool have focussed on the use of 'expanded criteria donors', including deceased cardiac donors (DCD). 'Reuse' transplant, where an organ is transplanted after removal from the first recipient, is a rare strategy, used more commonly in liver than in kidney transplantation...

BACKGROUND: The endogenously produced gaseous molecule carbon monoxide is able to promote organ protection after ischemia-reperfusion injuries (IRI). The impact of carbon monoxide releasing molecules (CORM) regarding inflammation in neuronal tissues has not been studied in detail. In this investigation, we aimed to analyze the effects of the CORM ALF-186 on neuro-inflammation and hypothesized that the soluble guanylate cyclase (sGC) is playing a decisive role. METHODS: Retinal ischemia-reperfusion injury was performed for 60 min in Sprague-Dawley rats...

BACKGROUND: Less-than-optimal long-term patency of the saphenous vein is one of the main obstacles for the success of coronary artery bypass grafting (CABG). Results from the IMPROVE-CABG trial has shown that harvesting the saphenous vein with a pedicle of perivascular tissue less than 5 mm while using manual distention provides comparable occlusion rates but significantly less intimal hyperplasia at early follow-up. The impact of pedicled veins on duration of operations, leg wound infections, and postoperative bleeding is unknown...

Background -Current consensus statements maintain that endoscopic vein harvesting (EVH) should be standard care in coronary artery bypass surgery (CABG) but vein quality and clinical outcomes have been questioned. The Vein Integrity and Clinical Outcome (VICO) trial was designed to assess the impact of different vein harvesting methods on vessel damage and if this contributes to clinical outcomes following CABG. Methods -A single centre, randomised clinical trial of patients undergoing CABG with an internal mammary artery, and with one to four vein grafts were recruited...

Duplicated inferior vena cava (IVC) is a rare congenital anomaly. We describe the utility of a new graft from the left IVC in a patient with duplicated IVC for reconstructing the middle hepatic vein (MHV) after partial hepatectomy with MHV resection. A 67-year-old woman with hepatitis C was found to have a liver tumor. Magnetic resonance imaging confirmed that the tumor, which was attached to the MHV, was hepatocellular carcinoma. Central bisectionectomy (S4, S5, and S8 resection) could not be tolerated because of poor liver function and a low future liver remnant volume...

This study aimed to develop a methodology for eliminating cassava frogskin disease (CFSD) from in vitro shoot tip culture by associating thermotherapy and tetracycline. Cuttings from different accessions (BGM0232, BGM0315, BGM0464, BGM584, BGM0841, and BGM1342), infected with CFSD according to visual inspection of the disease symptoms, were used for cleaning. To verify the absence of other diseases, the plants were indexed for Cassava common mosaic virus - CsCMV (by ELISA) and Cassava vein mosaic virus - CsVMV (by polymerase chain reaction, PCR), proving that the accessions were free of these viruses, except for BGM0315 and BGM0464, which were infected with CsVMV...

BACKGROUND: In the field of experimental facial vascularized composite tissue allotransplantation (VCA), a human auricular subunit model, pedicled on both superficial temporal (STA) and posterior auricular (PAA) arteries was described. Clinical cases of extensive auricular replantation however, suggested that a single artery could perfuse the entire flap. In our study, variants of this single pedicle approach have been studied, aiming to develop a more versatile replantation technique, in which the question of venous drainage has also been addressed...

Using transcriptional profiling of platelets from patients presenting with acute myocardial infarction, we identified myeloid-related protein-14 (MRP-14, also known as S100A9) as an acute myocardial infarction gene and reported that platelet MRP-14 binding to platelet CD36 regulates arterial thrombosis. However, whether MRP-14 plays a role in venous thrombosis is unknown. We subjected WT and Mrp-14-deficient (Mrp-14-/-) mice to experimental models of deep vein thrombosis (DVT) by stasis ligation or partial flow restriction (stenosis) of the inferior vena cava...

PURPOSE: We previously showed that intravitreal injection of the sFLT morpholino-oligomer (FLT-MO) suppresses laser-induced choroidal neovascularization (CNV) in mice by decreasing the membrane bound form of Flt-1 while increasing the soluble form of Flt-1 via alternative splicing shift. In this study, we examined whether cyclic RGD peptide (cRGD) can promote morpholino-oligomer accumulation in CNV following tail vein injection, and whether systemic cRGD conjugated FLT-MO (cRGD-FLT-MO) suppresses CNV growth...

BACKGROUND: Neointimal hyperplasia, which is caused by dysfunction of vascular smooth muscle cells and vascular endothelial cells (VECs), is a foundation for later development of vein grafted occlusion. This study investigates whether neointimal hyperplasia could be prevented by the application of paeonol, a phenolic compound having functions of anti-inflammatory, anti-oxidant, and anti-proliferative. METHODS: Autologous jugular veins, which engrafted to carotid arteries in rabbits, were enveloped with paeonol or left untreated...

BACKGROUND: Deep wound infections in the groin region can result in an acute or life-threatening condition. Especially, when there is no suitable vein available because of many reasons (e.g., previous bypass surgery, small vessel diameter). Synthetic prosthesis is not always the "first-choice technique" because of contamination or infection. It was ad hoc hypothesized in an acute setting that a segment of an occluded superficial femoral artery (SFA) could be used as a conduit in combination with eversion technique, known from carotid surgery...
