Electrosclerotherapy for capillary malformations: study protocol for a randomised within-patient controlled pilot trial.

Introduction: The current state-of-the-art treatment modality for hypertrophic capillary malformations (CMs), laser therapy, has a considerable rate of non-responders and recurrence. Intralesional bleomycin injections (or 'sclerotherapy') are commonly used to treat venous and lymphatic malformations with an excellent effect, but these intravascular injections are not possible in CMs due to the small diameter of the vessels. Electroporation-an electric field applied to the tissue-could increase the permeability of endothelial cells, which could theoretically facilitate targeted localised bleomycin delivery.

Repetitive freshwater diving: risk factors and prevalence of barotrauma.

Objective: The aim was to investigate the influence of repetitive scuba diving in fresh water on the middle ear mucosa. The prevalence of middle ear barotrauma (MEB) and risk factors for MEB were evaluated.

Study Design: Prospective cohort study, Level of evidence 1b.

Recurrent De Novo Mutations Disturbing the GTP/GDP Binding Pocket of RAB11B Cause Intellectual Disability and a Distinctive Brain Phenotype.

The Rab GTPase family comprises ∼70 GTP-binding proteins, functioning in vesicle formation, transport and fusion. They are activated by a conformational change induced by GTP-binding, allowing interactions with downstream effectors. Here, we report five individuals with two recurrent de novo missense mutations in RAB11B; c.

Stellarex drug-coated balloon for treatment of femoropopliteal arterial disease-The ILLUMENATE Global Study: 12-Month results from a prospective, multicenter, single-arm study.

Objectives: The purpose of this study was to assess the safety and performance of Stellarex Drug-coated balloon (DCB).

Background: DCB coatings differ in excipients, paclitaxel dose, and coating morphologies. Due to these differences, a class effect with DCBs has not been demonstrated.

Multidisciplinary Clinic Management of Head and Neck Cancer.

Importance: Contemporary management of head and neck cancer involves professionals from multiple specializations. Streamlined care that reduces delays yet allows for comprehensive evaluation is needed.

Objective: To evaluate a single-day, single-appointment, multidisciplinary head and neck clinic model for reduction in treatment delay and comprehensiveness of care.

Vessel diameter is related to amount and spatial arrangement of axial parenchyma in woody angiosperms.

Parenchyma represents a critically important living tissue in the sapwood of the secondary xylem of woody angiosperms. Considering various interactions between parenchyma and water transporting vessels, we hypothesize a structure-function relationship between both cell types. Through a generalized additive mixed model approach based on 2,332 woody angiosperm species derived from the literature, we explored the relationship between the proportion and spatial distribution of ray and axial parenchyma and vessel size, while controlling for maximum plant height and a range of climatic factors.

Plant water potential improves prediction of empirical stomatal models.

Climate change is expected to lead to increases in drought frequency and severity, with deleterious effects on many ecosystems. Stomatal responses to changing environmental conditions form the backbone of all ecosystem models, but are based on empirical relationships and are not well-tested during drought conditions. Here, we use a dataset of 34 woody plant species spanning global forest biomes to examine the effect of leaf water potential on stomatal conductance and test the predictive accuracy of three major stomatal models and a recently proposed model.

High Liver Enzyme Concentrations are Associated with Higher Glycemia, but not with Glycemic Variability, in Individuals without Diabetes Mellitus.

Background: Elevated concentrations of liver enzymes have been associated with an increased risk of developing type 2 diabetes mellitus. However, it remains unclear to which specific aspects of diurnal glucose metabolism these associate most. We aimed to investigate the associations between liver enzyme concentrations and 24 h-glucose trajectories in individuals without diabetes mellitus from three independent cohorts.

Detection and characterization of a novel rhabdovirus in Aedes cantans mosquitoes and evidence for a mosquito-associated new genus in the family Rhabdoviridae.

Thanks to recent advances in random amplification technologies, metagenomic surveillance expanded the number of novel, often unclassified viruses within the family Rhabdoviridae. Using a vector-enabled metagenomic (VEM) tool, we identified a novel rhabdovirus in Aedes cantans mosquitoes collected from Germany provisionally named Ohlsdorf virus (OHSDV). The OHSDV genome encodes the canonical rhabdovirus structural proteins (N, P, M, G and L) with alternative ORF in the P gene.

Methanogens predominate in natural corrosion protective layers on metal sheet piles.

Microorganisms are able to cause, but also to inhibit or protect against corrosion. Corrosion inhibition by microbial processes may be due to the formation of mineral deposition layers on metal objects. Such deposition layers have been found in archaeological studies on ancient metal objects, buried in soil, which were hardly corroded.

Paving the Rho in cancer metastasis: Rho GTPases and beyond.

Malignant carcinomas are often characterized by metastasis, the movement of carcinoma cells from a primary site to colonize distant organs. For metastasis to occur, carcinoma cells first must adopt a pro-migratory phenotype and move through the surrounding stroma towards a blood or lymphatic vessel. Currently, there are very limited possibilities to target these processes therapeutically.

Culex torrentium mosquitoes from Germany are negative for Wolbachia.

Wolbachia (Rickettsiales: Anaplasmataceae) infects a wide range of arthropods, including several mosquito species. The bacterium is known to induce a plethora of phenotypes in its host, examples being the reproductive phenotype cytoplasmic incompatibility or resistance against infection with arboviruses. The latter is especially relevant when assessing the vector competence of mosquito species for emerging arboviruses.

Review of aspirin and clopidogrel resistance in peripheral arterial disease.

Objective: Aspirin resistance (AR) and clopidogrel resistance (CR) are terms used to describe a reduction in the medication's efficacy in inhibiting platelet aggregation despite regular dosing. This review gives context to the clinical role and implications of antiplatelet resistance in peripheral arterial disease (PAD).

Methods: A review of English-language literature on AR and CR in PAD involving human subjects using PubMed and MEDLINE databases was performed in April 2017.

Conformational dynamics are a key factor in signaling mediated by the receiver domain of a sensor histidine kinase from .

Multistep phosphorelay (MSP) cascades mediate responses to a wide spectrum of stimuli, including plant hormonal signaling, but several aspects of MSP await elucidation. Here, we provide first insight into the key step of MSP-mediated phosphotransfer in a eukaryotic system, the phosphorylation of the receiver domain of the histidine kinase CYTOKININ-INDEPENDENT 1 (CKI1) from We observed that the crystal structures of free, Mg-bound, and beryllofluoridated CKI1 (a stable analogue of the labile phosphorylated form) were identical and similar to the active state of receiver domains of bacterial response regulators. However, the three CKI1 variants exhibited different conformational dynamics in solution.

Thirty Minutes of Hypobaric Hypoxia Provokes Alterations of Immune Response, Haemostasis, and Metabolism Proteins in Human Serum.

Hypobaric hypoxia (HH) during airline travel induces several (patho-) physiological reactions in the human body. Whereas severe hypoxia is investigated thoroughly, very little is known about effects of moderate or short-term hypoxia, e.g.

Acute Global Testicular Infarction Post-EVAR from Cholesterol Embolisation can be Mistaken for Torsion.

Introduction: Endovascular aneurysm repair (EVAR) is the most commonly used approach for treatment of abdominal aortic aneurysms (AAA). Testicular infarction is a rare complication of EVAR. A novel case of acute global testicular infarction post-EVAR from cholesterol embolisation mimicking torsion is presented.

New trend in colorectal cancer in Germany: are young patients at increased risk for advanced colorectal cancer?

Background: The role of colonoscopy in the screening of colorectal cancer (CRC) has been unequivocally established. In Germany, screening colonoscopy with full insurance reimbursement is available for individuals aged 55 and above, and/or for persons with well-known risk factors for CRC. However, advanced CRC is not uncommon in individuals below 55 years.

Applicability of quantitative optical imaging techniques for intraoperative perfusion diagnostics: a comparison of laser speckle contrast imaging, sidestream dark-field microscopy, and optical coherence tomography.

Patient morbidity and mortality due to hemodynamic complications are a major problem in surgery. Optical techniques can image blood flow in real-time and high-resolution, thereby enabling perfusion monitoring intraoperatively. We tested the feasibility and validity of laser speckle contrast imaging (LSCI), optical coherence tomography (OCT), and sidestream dark-field microscopy (SDF) for perfusion diagnostics in a phantom model using whole blood.

Tissue sublimation follow transarterial embolization of a follicular nodular hyperplasia of the liver-report of a case.

Background: Follicular nodular hyperplasia (FNH) is a common benign liver tumor for which conservative management is indicated. Surgical or interventional management is indicated in symptomatic cases. Transarterial embolization (TAE) has been extensively used to manage unresectable liver tumors.

Bordered pits in xylem of vesselless angiosperms and their possible misinterpretation as perforation plates.

Vesselless wood represents a rare phenomenon within the angiosperms, characterizing Amborellaceae, Trochodendraceae and Winteraceae. Anatomical observations of bordered pits and their pit membranes based on light, scanning and transmission electron microscopy (SEM and TEM) are required to understand functional questions surrounding vesselless angiosperms and the potential occurrence of cryptic vessels. Interconduit pit membranes in 11 vesselless species showed a similar ultrastructure as mesophytic vessel-bearing angiosperms, with a mean thickness of 245 nm (± 53, SD; n = six species).

Determinants of lifestyle behavior change to prevent type 2 diabetes in high-risk individuals.

Background: Although there are many effective lifestyle interventions for type 2 diabetes (T2DM) prevention, insight into effective intervention pathways, especially of long-term interventions, is often lacking. This study aims to provide insight into the effective intervention pathways of the SLIMMER diabetes prevention intervention using mediation analyses.

Methods: In total, 240 participants at increased risk of T2DM were included in the analyses over 18 months.

Phenotypes and genotypes in individuals with SMC1A variants.

SMC1A encodes one of the proteins of the cohesin complex. SMC1A variants are known to cause a phenotype resembling Cornelia de Lange syndrome (CdLS). Exome sequencing has allowed recognizing SMC1A variants in individuals with encephalopathy with epilepsy who do not resemble CdLS.

Is the success of the SLIMMER diabetes prevention intervention modified by socioeconomic status? A randomised controlled trial.

Aim: To explore the role of socioeconomic status (SES) in participation, programme attendance, programme acceptability, adherence to lifestyle guidelines, drop-out, and effectiveness in the SLIMMER diabetes prevention intervention.

Methods: SLIMMER was a randomised controlled intervention, carried out in a real-world setting, targeting 40- to 70-year-old adults at increased risk of developing type 2 diabetes (n=316). The intervention group participated in a 10-month combined dietary and physical activity programme.
