The quadratus plantae (QP) is a highly variable structure. A number of partly inexact descriptions of this entity have been provided in textbooks of anatomy. Although several authors have examined the QP, its exact site of origin and type of insertion have hitherto not been specified. The aim of this study has been to provide detailed qualitative and quantitative data about the number of heads, points of origin, and type of insertion of the QP. The QP in both feet of 50 formalin-fixed specimens of body donors (25 men and women) were analyzed by gross anatomical dissection...

The spinal accessory nerve (SAN) or XI cranial nerve is frequently encountered during neck surgery, and as such is at risk of iatrogenic injury, resulting in "shoulder syndrome". Modified neck dissection (MND) with preservation of the SAN is based on desire to minimise the functional deformity associated with section of the eleventh nerve. The aim of this study was to analyse the intra-operative variations of the spinal accessory nerve pathway and to evaluate shoulder dysfunction postoperatively. The cross-sectional demonstration analysis was created through the medical records retrospectively of 165 consecutive patients who underwent neck dissections at our institution in the past 5 years with attention to ultrasound and MRI preoperative findings, type of neck dissection, type of identification and dissection of SAN, postoperative morbidity and survival rate...

PURPOSE: Endovascular repair of true visceral artery aneurysms (VAAs) and pseudoaneurysms (VAPAs) with stent-grafting (SG) can simultaneously allow aneurysm exclusion and vessel preservation, minimizing the risk of ischemic complications. Our aim was to report a single-center experience on SG of visceral aneurysms, focusing on technical aspects, clinical outcome and mid-term patency. MATERIALS AND METHODS: Consecutive patients affected by VAAs-VAPAs and submitted to endovascular treatment were retrospectively reviewed, and SG cases with the self-expandable peripheral Viabahn stent-graft were analyzed (2003-2017)...

Periodontitis is a chronic inflammatory response to a microbial biofilm that destroys bone and soft tissues supporting the teeth. Murine models of periodontitis based on Porphyromonas gingivalis (Pg) colonization have shown that extravasation of leukocytes into oral tissue is critical to driving alveolar bone destruction. Identifying interstitial leukocytes is key to understanding the immunopathogenesis of periodontitis. Here, we describe a robust flow cytometry assay based on intravenous FITC-conjugated anti-mouse CD45 mAb that distinguishes interstitial leukocytes in the oral mucosa of mice from those circulating within the vasculature or in post-dissection contaminating blood...

OBJECTIVES: The best surgical strategy for acute Stanford Type A aortic dissection (aTAAD) involving the arch remains controversial. Here, we report on the satisfactory results following aTAAD repair using a novel arch fenestrated stent graft. METHODS: From December 2014 to December 2015, 42 aTAAD patients (27 male and 15 female) underwent ascending aorta replacement and fenestrated stent graft implantation. The fenestrated stent graft was implanted into the true lumen of the aortic arch and proximal descending aorta, with the fenestration opening located at the ostia of 3 head vessels in the arch...

BACKGROUND: Open surgical repair remains the "gold standard" treatment for chronic type B aortic dissection (cTBD) with aneurysm. Thoracic endovascular aortic repair (TEVAR) has gained popularity in recent years for the treatment of thoracic aortic diseases, including cTBD. We assessed the effectiveness of TEVAR in the treatment of cTBD using the Vascular Quality Initiative (VQI) database. METHODS: The VQI registry identified 4713 patients treated with TEVAR from July 2010 to November 2015, including 125 repairs for cTBD...

OBJECTIVES: Type 1a endoleak is one of the most severe complications after thoracic endovascular aortic repair (TEVAR), because it carries the risk of aortic rupture. The association between bird-beak configuration and Type 1a endoleak remains unclear. The purpose of this study was to analyse the predictors of Type 1a endoleak following Zone 1 and Zone 2 TEVAR, with a particular focus on the effect of bird-beak configuration. METHODS: From April 2008 to July 2015, 105 patients (mean age 68...

A 45-year-old man with acute Type A aortic dissection underwent the ascending aorta replacement with BioGlue (CryoLife Europa, Guildford, Surrey, UK) for anastomotic reinforcement. Postoperatively, he developed descending aortic dilation, a giant mediastinal cyst, Henoch-Schonlein purpura and an anastomotic-site pseudoaneurysm rupture. A BioGlue-induced inflammatory reaction was likely, according to a positive patch test (delayed allergic reaction).

Nervous system development involves a sequential series of events that are coordinated by several signaling pathways and regulatory networks. Many of the proteins involved in these pathways are evolutionarily conserved between mammals and other eukaryotes, such as the fruit fly Drosophila melanogaster, suggesting that similar organizing principles exist during the development of these organisms. Importantly, Drosophila has been used extensively to identify cellular and molecular mechanisms regulating processes that are required in mammals including neurogenesis, differentiation, axonal guidance, and synaptogenesis...

In operations for acute Stanford type A aortic dissection, several cannulation options are available for cardiopulmonary bypass arterial perfusion. These are femoral, axillary, Seldinger ascending aortic, transapical, and transatrial, each of which has advantages and drawbacks. We describe our surgical technique of direct true lumen cannulation ("Samurai" cannulation), which represents an easy, safe, and practical option in operations for acute type A aortic dissection.

A 72-year-old man previously treated for an abdominal aortic aneurysm (AAA) was diagnosed with the 70-mm-sized type IIIb aortic dissection. Endovascular repair was considered, but there was no stent graft passing through the 8-mm iliac graft that was used for open repair of the AAA. We sealed the 5-mm-sized intimal tear site, using an Amplatzer Vascular Plug, which successfully repaired. The patient was discharged and had no complications. Serial follow-up computerized tomography scans showed that the vascular plug was positioned without migration, and the size of the aorta decreased...

INTRODUCTION: The persistence of dentin-bound lipopolysaccharides (LPS) in disinfected root canals impedes treatment outcomes of endodontic procedures. This study assessed the effects of photoactivated rose bengal-functionalized chitosan nanoparticles (CSRBnps) on LPS-contaminated root dentin in vivo using an intraosseous implantation model and neotissue formation as a marker. METHODS: Fifty human, 3-mm-long root segments with a 1.2-mm canal lumen were divided into 5 groups (n = 10): group 1, canals not contaminated; group 2, canals contaminated with Pseudomonas aeruginosa LPS; group 3, canals contaminated and disinfected with sodium hypochlorite (NaOCl); group 4, canals contaminated and disinfected with NaOCl and calcium hydroxide; and group 5, canals contaminated and disinfected with NaOCl and CSRBnps (300 μg/mL) with photoactivation (λ = 540 nm, 40 J/cm(2))...

BACKGROUND: Current treatment options and outcomes for acute uncomplicated thoracic Type-B aortic dissection (TBAD) remain unclear between medical management (MED) and thoracic endovascular aortic repair (TEVAR). In this study we aim to compare both strategies in terms of all-cause mortality, aortic dilation, and aortic rupture. METHODS: MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials were queried from January 1990 through March 2017. Only studies comparing TEVAR to MED for acute uncomplicated TBAD were included...

Cell metabolism is a key determinant factor for the pluripotency and fate commitment of Stem Cells (SCs) during development, ageing, pathological onset and progression. We derived and cultured selected subpopulations of rodent fetal, postnatal, adult Neural SCs (NSCs) and postnatal glial progenitors, Olfactory Ensheathing Cells (OECs), respectively from the subventricular zone (SVZ) and the olfactory bulb (OB). Cell lysates were analyzed by proton Nuclear Magnetic Resonance ((1)H-NMR) spectroscopy leading to metabolites identification and quantitation...

Membrane-assisted amyloid formation is implicated in human diseases, and many of the aggregating species accelerate amyloid formation and induce cell death. While structures of membrane-associated intermediates would provide tremendous insights into the pathology and aid in the design of compounds to potentially treat the diseases, it has not been feasible to overcome the challenges posed by the cell membrane. Here we use NMR experimental constraints to solve the structure of a type-2 diabetes related human islet amyloid polypeptide intermediate stabilized in nanodiscs...

Traditionally, the surgical management of acute type B aortic dissections was reserved for patients with signs of malperfusion, rapid expansion, retrograde dissection or rupture. The adjunct of endovascular techniques has brought a paradigm shift, leaning towards preventing long term dissection complications. Multiple risk factors have been proposed to identify patients at risk for long term aortic complications. The patients, who are offered a prophylactic endovascular therapy for uncomplicated aortic dissection, should be selected carefully, and offered intervention by an experienced team in a high-volume center...
