Pulpal revascularization is commonly used in the dental clinic to obtain apical closure of immature permanent teeth with thin dentinal walls. Although sometimes successful, stimulating bleeding from the periapical area of the tooth can be challenging and in turn may deleteriously affect tooth root maturation. Our objective here was to define reliable methods to regenerate pulp-like tissues in tooth root segments (RSs). G1 RSs were injected with human dental pulp stem cells (hDPSCs) and human umbilical vein endothelial cells (HUVECs) encapsulated in 5% gelatin methacrylate (GelMA) hydrogel...

INTRODUCTION: Minimal evidence exists to guide the surgeon on the risk of complications when performing abdominal wall reconstruction (AWR) in the presence of active infection, contamination or enterocutaneous fistula. This study aims to establish the outcomes of contaminated complex AWR. METHODS: Analysis was conducted according to PRISMA guidelines. Systematic search of the MEDLINE, EMBASE and Pubmed databases was performed. Studies reporting exclusively on single-staged repair of contaminated complex AWR were included...

Exotic domain morphologies in ferroic materials are an exciting avenue for the development of novel nanoelectronics. In this work we have used large scale molecular dynamics to construct a strain-temperature phase diagram of the domain morphology of PbTiO3 ultrathin films. Sampling a wide interval of strain values over a temperature range up to the Curie temperature Tc, we found that epitaxial strain induces the formation of a variety of closure- and in-plane domain morphologies. The local strain and ferroelectric-antiferrodistortive coupling at the film surface vary for the strain mediated transition sequence and this could offer a route for experimental observation of the morphologies...

INTRODUCTION: Open abdomen management has become a well-established strategy in the treatment of serious intra-abdominal pathologies. Key objectives are fistula prevention and high fascial closure rates. The current level of evidence on laparostoma is insufficient. This is due to the rareness of laparostomas, the heterogeneity of study cohorts, and broad diversity of techniques. Collecting data in a standardised, multicentre registry is necessary to draw up evidence-based guidelines. MATERIALS AND METHODS: In order to improve the level of evidence on laparostomy, CAMIN (surgical working group for military and emergency surgery) of DGAV (German Society for General and Visceral Surgery), initiated the implementation of a laparostomy registry...

Cardiac rupture (CR) is one of the most serious and life-threatening complications of blunt chest trauma (BCT) usually associated with high mortality. Moreover, its diagnosis and treatment strategies may be extremely challenging for clinicians due to various anatomical localisations of the tear. Whereas most injuries fall under the category of right atrial ruptures, left ventricular lesions represent a rare type of this injury, with greater mortality, particularly in cases of multi-chamber injuries. However, not only cardiac chamber or great vessel ruptures may occur as a result of BCT; a growing number of reports also describe BCT-induced isolated coronary artery injuries, including ruptures...

BACKGROUND: Congenital cranial bone defects predispose to herniation of meninges, sometimes with brain tissue involvement, to form a cerebrospinal fluid (CSF)-filled cyst in the head. Such defects mainly results from focal failure of neural tube closure during fetal development and has been reported in various species of domestic mammals. CASE PRESENTATION: A one week old Ayrshire calf with a fluctuant swelling on parieto-occipital region of the head was referred to the faculty...

Anoscrotal fistula is an extremely rare condition involving an epithelialised tract between the anal canal and scrotal wall. It is more commonly seen as a congenital phenomenon in the paediatric population, and has not previously been described in the literature in adults. We present the case of a man aged 52 years who developed a complex anoscrotal fistula after a radical inguinal orchidectomy for an intratesticular seminoma. A postsurgical wound-site infection developed into a chronically discharging wound refractory to antibiotic treatment prompting further investigation...

Cardiac muscle stiffness can potentially be estimated non-invasively with shear wave elastography. Shear waves are present on the septal wall after mitral and aortic valve closure, thus providing an opportunity to assess stiffness in early systole and early diastole. We report on the shear wave recordings of 22 minipigs with high-frame-rate echocardiography. The waves were captured with 4000 frames/s using a programmable commercial ultrasound machine. The wave pattern was extracted from the data through a local tissue velocity estimator based on one-lag autocorrelation...

Stereotactic radiosurgery (SRS) is an established treatment for brain arteriovenous malformations (AVMs) that drives blood vessel closure through cellular proliferation, thrombosis and fibrosis, but is limited by a delay to occlusion of 2-3 years and a maximum treatable size of 3 cm. In this current study we used SRS as a priming tool to elicit novel protein expression on the endothelium of irradiated AVM vessels, and these proteins were then targeted with prothrombotic conjugates to induce rapid thrombosis and vessel closure...

OBJECTIVES: We aimed to develop a simple, reliable, and timesaving technique for the therapy of thoracoabdominal aortic (TAA) aneurysms that are not suitable for endovascular repair. METHODS: In this pilot study, we sought to combine the advantages of classic open vascular procedure with the use of endoscopic surgical tools and small skin incisions to develop a minimally invasive approach for TAA replacement. The following procedures were used: endoscopic exposure and closure of the lower intercostal arteries; small posterolateral thoracotomy and left retroperitoneal incisions to expose the anastomotic regions of the aorta; partial anticoagulation; passive bypass and sequential aortic clamping; tunnelling of the graft through the native aortic lumen (endoaneurysmorrhaphy) and open performance of vascular anastomosis...

BACKGROUND: Most skin defects that require reconstruction with a local skin flap have a circular- or oval-shaped pattern. The majority of the skin flaps are planned in an angled shape. Therefore, it may be necessary to modify the shape of the defect or the distal flap border to minimize tissue distortion. We have designed a circular-shaped advancement flap to be compatible with the circular defect. METHODS: Eighteen cases of reconstruction of skin defects in the face, chest wall, hand and buttock area were performed using the omega advancement flap between 2010 and 2014...

INTRODUCTION: Gastroschisis (GS) is a common abdominal wall defect necessitating neonatal surgery and intensive care. We hypothesized that inborn patients had improved outcomes compared to patients born at an outside hospital (outborn) and transferred for definitive treatment. METHODS: A single center, retrospective chart review at a pediatric tertiary care center was performed from 2010 to 2015. All patients whose primary surgical treatment of GS was performed at this center were included...

Peptidoglycan (PG), an essential stress-bearing component of the bacterial cell wall, is synthesised by penicillin binding proteins (PBPs). PG synthesis at the cell division septum is necessary for constructing new poles of progeny cells, and cells cannot elongate without inserting new PG in the side-wall. The cell division regulator GpsB appears to co-ordinate PG synthesis at the septum during division and at the side-wall during elongation in rod-shaped and ovococcoid Gram-positive bacteria. How the control over PG synthesis is exerted is unknown...

GpsB regulatory protein and StkP protein kinase have been proposed as molecular switches that balance septal and peripheral (side-wall like) peptidoglycan (PG) synthesis in Streptococcus pneumoniae (pneumococcus); yet, mechanisms of this switching remain unknown. We report that ΔdivIVA mutations are not epistatic to ΔgpsB division-protein mutations in progenitor D39 and related genetic backgrounds; nor is GpsB required for StkP localization or FDAA labeling at septal division rings. However, we confirm that reduction of GpsB amount leads to decreased protein phosphorylation by StkP and report that the essentiality of ΔgpsB mutations is suppressed by inactivation of PhpP protein phosphatase, which concomitantly restores protein phosphorylation levels...
