We introduce an innovative specimen preparation method employing the selectivity of a wet-chemical etching step to improve data quality and success rates in the atom probe analysis of contemporary semiconductor devices. Firstly, on the example of an SiGe fin embedded in SiO2 we demonstrate how the selective removal of SiO2 from the final APT specimen significantly improves accuracy and reliability of the reconstructed data. With the oxide removal, we eliminate the origin of shape artefacts, i.e. the formation of a non-hemispherical tip shape, that are typically observed in the reconstructed volume of complex systems...

Struvite (MgNH4PO4·6H2O) forms in aqueous systems with high ammonia and phosphate concentrations. However, conditions that result into struvite formation are highly dependent on the ionic compositions, temperature, pH, and ion speciation characteristics. The primary ions involved in struvite formation have complex interactions and can form different crystals depending on the ionic levels, pH and temperature. Struvite as well as struvite analogues (with substitution of monovalent cations for NH4+ or divalent cations for Mg2+) as well as other crystals can form simultaneously and result in changes in crystal morphology during crystal growth...

Influenza pathogenesis comprises a complex cascade of impaired cellular processes resulting from the viral replication and exaggerated immune response accompanied by reactive oxygen species (ROS) burst and oxidative stress, destructing membranous structures and tissues. By classical virological and biochemical methods we compared and evaluated the therapeutic effects of 2.5mg/kg/day of the antiviral drug - oseltamivir (OS), 500mg/kg/day of the immune modulator - isoprinosine (IP) and 500mg/kg/day of the antioxidant agent ellagic acid (EA) with a focus on their combined activities in influenza H3N2 virus-infected mice...

Fatty-acid binding proteins (FABP) and myeloperoxidases (MPO) are associated with many chronic conditions in humans and considered to be important biomarkers for diagnosis of cardiac diseases. Here we assemble a new electrical biosensor platform based on graphene-coated interdigitated electrode arrays (IDE-arrays) towards ultrafast, label-free screening of heart type-FABP and MPO. Arrays of nanoscale (nanoIDE) and microscale (microIDE) electrode-arrays were fabricated on wafer-scale by combining nanoimprint and photolithography processes...

Sports medical examinations of juvenile athletes provide an opportunity for preventive measures against sports-related diseases. Determining the leg axis deviation as a risk factor for future constraints may offer approaches for such measures. Data were obtained from 789 youth athletes: 166 with coronal plane knee misalignment and 623 without. After a seven-year period, 64 participants (m: 33, f: 31) from both groups were reassessed for the incidence of nonspecific chronic low back pain (CLBP). To distinguish participants with increased risk for CLBP, contingency tables for comparison of expected and joint frequency distribution testing and receivers operating characteristic (ROC) analyses for the weekly training time were conducted...

Hexopyranose side chains populate three staggered conformations, whose proportions can be determined from the three sets of ideal limiting 3JH5,H6R and 3JH5,H6S coupling constants in combination with the time-averaged experimental coupling constants. Literature values for the limiting coupling constants, obtained by the study of model compounds, the use of the Haasnoot-Altona and related equations, or quantum mechanical computations, can result in computed negative populations of one of the three ideal conformations...

Fluorogenic bioorthogonal probe is ideal for fluorescent imaging in live cell condition. By taking advantage of dual functionality of tetrazine (Tz), bioorthogonal reaction unit as well as fluorescence quencher, fluorophore-Tz conjugate (FLTz) has been utilized for fluorescent live cell imaging via inverse electron-demand Diels-Alder (iEDDA) type bioorthogonal reaction. However, most of FLTz strategies rely on donor-acceptor type energy transfer mechanism which limits red-shifting of probes' emission wavelength without deterioration of fluorescent turn-on/off ratio...

BACKGROUND: Common genetic polymorphisms at chromosome 4q25 were associated with increased susceptibility to atrial fibrillation (AF). However, it remained controversial whether these variants could be used as risk predictors for AF recurrence after catheter ablation. We therefore performed a meta-analysis to quantify the association between rs2200733 C>T/rs10033464 G>T and AF recurrence. METHODS: Relevant studies were systematically retrieved from PubMed, Web of science, Elsevier database and Cochrane library through November 2016...

In urban and suburban areas larvae of the pine processionary moth, Thaumetopoea pityocampa (Denis and Schiffermüller), cause serious defoliation to Cedrus, Pinus, and Pseudotsuga trees and health problems to humans and domestic or farm animals by their urticating setae. In this study, we present the results of biennial trials (2015-2016) on the management of T. pityocampa infestations using commercial or LIFE-PISA prototype trunk barrier and adhesive trap devices in Greece (Attica and Volos), Spain (Valencia), and Italy (Molise)...

OBJECTIVES: Pulmonary sarcomatoid carcinoma (PSC) is a rare malignant neoplasm that accounts for a small percentage of non-small-cell lung carcinoma (NSCLC). At least 10% of PSCs has a spindle and/or giant cell component, which is often associated with a poor prognosis. We reviewed the Surveillance, Epidemiology, and End Results (SEER) database for the clinicopathological characteristics and surgical outcomes of PSCs. METHODS: The SEER database (1973-2013) was queried for PSC...

Background and Aims: There is a lack in the literature about prepouch ileitis [PI], in particular regarding risk factors associated with failure of the medical treatment. Aim of the study is to analyse the characteristics of PI patients and to compare those who required surgery with those who were successfully treated with conservative therapy. Methods: All cases presenting a diagnosis of PI were included and analysed. Patients eventually requiring surgery were compared with those who were managed conservatively, for symptoms of presentation, endoscopic characteristics, and rate of response to medical treatment...

Anthropometric data collected in clinics and surveys are often inaccurate and unreliable due to measurement error. The Body Imaging for Nutritional Assessment Study (BINA) evaluated the ability of 3D imaging to correctly measure stature, head circumference (HC) and arm circumference (MUAC) for children under five years of age. This paper describes the protocol for and the quality of manual anthropometric measurements in BINA, a study conducted in 2016-17 in Atlanta, USA. Quality was evaluated by examining digit preference, biological plausibility of z-scores, z-score standard deviations, and reliability...

Dilated cardiomyopathy (DCM) is the major cause of heart failure affecting both women and men. Limited clinical studies show conflicting data in sex-related differences in the progression of dilated cardiomyopathy and heart failure (HF) outcomes. We examined the comparative sex-related progression of cardiomyopathy and the development of HF (at 4, 7, 13 weeks of age) in a well-established, transgenic mouse model of DCM that recapitulates the progressive stages of human HF. By 13 weeks of age, female mice with DCM had more severe left ventricular systolic dysfunction, left ventricular dilation and wall thinning (P<0...

INTRODUCTION: Neisseria gonorrhoeae (NG) antimicrobial susceptibility trends to azithromycin, cefixime and ceftriaxone were analyzed, from 2009 to 2016, to monitor changing antimicrobial susceptibility concomitant with the change in prescribing practice in 2012 from cefixime, or ceftriaxone, to ceftriaxone plus azithromycin. Patient characteristics predictive to be infected by antibiotic resistant N. gonorrhoeae were estimated. Finally, the protocol for the treatment of gonorrhoea, in comparison with the international guidelines, was also evaluated...

The "number sense" describes the intuitive ability to quantify without counting. Single neuron recordings in non-human primates and functional imaging in humans suggest the intraparietal sulcus is an important neuroanatomical locus of numerical estimation. Other lines of inquiry implicate the IPS in numerous other functions, including attention and decision making. Here we provide a direct test of whether IPS has functional specificity for numerosity judgments. We used muscimol to reversibly and independently inactivate the ventral and lateral intraparietal areas in two monkeys performing a numerical discrimination task and a color discrimination task, roughly equilibrated for difficulty...

Xinxin Wang, Anders E Carlsson
We present a Master Equation approach to calculating polymerization dynamics and force generation by branched actin networks at membranes. The method treats the time evolution of the F-actin distribution in three dimensions, with branching included as a directional spreading term. It is validated by comparison with stochastic simulations of force generation by actin polymerization at obstacles coated with actin "nucleation promoting factors" (NPFs). The method is then used to treat the dynamics of actin polymerization and force generation during endocytosis in yeast, using a model in which NPFs form a ring around the endocytic site, centered by a spot of molecules attaching the actin network strongly to the membrane...
