Coronary perforation is a potential complication of chronic total occlusion (CTO) percutaneous coronary intervention (PCI). We analyzed 2,097 CTO PCIs performed in 2,049 patients from 2012 to 2017. Patient age was 65 ± 10 years, 85% were men, and 36% had prior coronary artery bypass graft surgery. Technical and procedural success were 88% and 87%, respectively. A major periprocedural adverse cardiovascular event occurred in 2.6%. Coronary perforation occurred in 85 patients (4.1%); The frequency of Ellis class 1, 2, and 3 perforations was 21%, 26%, and 52%, respectively...

The RNA chaperone Hfq is an Sm protein that facilitates base pairing between bacterial small RNAs (sRNAs) and mRNAs involved in stress response and pathogenesis. Hfq possesses an intrinsically disordered C-terminal domain (CTD) that may tune the function of the Sm domain in different organisms. In Escherichia coli, the Hfq CTD increases kinetic competition between sRNAs and recycles Hfq from the sRNA-mRNA duplex. Here, de novo Rosetta modeling and competitive binding experiments show that the acidic tip of the E...

Sphingosine kinase 1 (SphK1), the enzyme that produces the bioactive sphingolipid metabolite, sphingosine-1-phosphate, is a promising new molecular target for therapeutic intervention in cancer and inflammatory diseases. In view of its importance, the main objective of this work was to find new and more potent inhibitors for this enzyme possessing different structural scaffolds than those of the known inhibitors. Our theoretical and experimental study has allowed us to identify two new structural scaffolds (three new compounds), which could be used as starting structures for the design and then the development of new inhibitors of SphK1...

A library of 29 homologous Ru-based olefin metathesis catalysts has been tested for ethenolysis of cyclic olefins towards the goal of selectively forming α,ω-diene using cis-cyclooctene as a prototypical substrate. Dissymmetry at the N-heterocyclic carbene (NHC) ligand was identified as a key parameter for controlling the selectivity. The best-performing catalyst bearing an N-CF3 group significantly outperformed the benchmark second-generation Grubbs catalyst in the ethenolysis of cis-cycloctene. Application of this optimal catalyst to the ethenolysis of various norbornenes allows the efficient synthesis of valuable diene intermediates in good yields...

Recent findings suggest that treatment with 11β-HSD1 inhibitors provides a novel approach to deal with age-related cognitive dysfunctions, including Alzheimer's disease. In this work we report potent 11β-HSD1 inhibitors featuring unexplored pyrrolidine-based polycyclic substituents. A selected candidate administered to 12-month-old SAMP8 mice for four weeks prevented memory deficits and displayed a neuroprotective action. This is the first time that 11β-HSD1 inhibitors have been studied in this broadly-used mouse model of accelerated senescence and late-onset Alzheimer's disease...

Assessments of vulnerability to climate change are a key element to inform climate policy and research. Assessments based on the aggregation of indicators have a strong appeal for their simplicity but are at risk of over-simplification and uncertainty. This paper explores the non-robustness of indicators-based assessments to changes in assumptions on the degree of substitution or compensation between indicators. Our case study is a nationwide assessment for New Zealand. We found that the ranking of geographic areas is sensitive to different parameterisations of the aggregation function, that is, areas that are categorised as highly vulnerable may switch to the least vulnerable category even with respect to the same climate hazards and population groups...

The mitochondrial genome is present at variable copy number between individuals. Mitochondria are vulnerable to oxidative stress, and their dysfunction may be associated with cardiovascular disease. The association of mitochondrial DNA copy number with cardiometabolic risk factors (lipids, glycaemic traits, inflammatory markers, anthropometry and blood pressure) was assessed in two independent cohorts of European origin women, one in whom outcomes were measured at mean (SD) age 30 (4.3) years (N=2278) and the second at 69...

BACKGROUND: Moniliophthora perniciosa is a phytopathogenic fungus responsible for witches' broom disease of cacao trees (Theobroma cacao L.). Understanding the molecular events during germination of the pathogen may enable the development of strategies for disease control in these economically important plants. In this study, we determined a comparative proteomic profile of M. perniciosa basidiospores during germination by two-dimensional SDS-PAGE and mass spectrometry. RESULTS: A total of 316 proteins were identified...

Asthma is a common disease in both high and lower income countries that starts early and persists often for life. A correct and accurate diagnosis, treatment and follow-up during childhood are essential for a better understanding of adult asthma and avoiding over- or under-treatment. Th2 inflammation in children with asthma symptoms is usually assessed by measuring with serum total IgE, blood eosinophilia and FeNO levels that may help to predict asthma, particularly in those infants and young children in whom lung function tests are difficult to perform...

The response of drylands to environmental gradients can be abrupt rather than gradual. These shifts largely occur unannounced and are difficult to reverse once they happen; their prompt detection is of crucial importance. The distribution of vegetation patch sizes may indicate the proximity to these shifts, but the use of this metric is hampered by a lack of large-scale studies relating these distributions to the provision of multiple ecosystem functions (multifunctionality) and comparing them to other ecosystem attributes, such as total plant cover...

Employees working in the hospitality industry are constantly exposed to occupational stressors that may lead employees into experiencing the burnout syndrome. Research addressing the interactive effects of control, community and value congruence, to alleviate the impact of workplace demands on experiencing burnout is relatively limited. The present study examined relationships among control, community and value congruence, and workplace demands and the three components of burnout. A sample of 418 employees working in a variety of hospitality associations including restaurants and hotels in Spain were recruited...

This article traces the historical evolution of ongoing theoretical debates in psychology in France from the 1940s until today. Its aim is to show how the conjunction of certain conditions was determinant for a rapid expansion of American-derived mainstream health psychology during the 1980s. The authors describe the French context in the post-World War II period that made possible the introduction of psychology courses at the university, which included the tensions between two epistemological orientations: experimental psychology and clinical psychology, the latter partly inspired by Politzer's concrete psychology...

The purpose of this study was to evaluate the psychometric properties of the Spanish version of the Fear of Pain Questionnaire-III. The original three-factor structure of the Fear of Pain Questionnaire-III was confirmed and indicated a good to excellent level of internal consistency. Criterion validity was supported by positive significant correlations between the Fear of Pain Questionnaire-III scores and measures of pain catastrophizing and anxiety sensitivity; discriminant validity was supported by non-significant correlations between the Fear of Pain Questionnaire-III scores and measures of pain intensity and depressive symptomatology...

In patients with home ventilation, there is a markedly higher probability for lower respiratory infections or pneumonia and severe courses due to comorbidity. Tracheobronchitis and pneumonia are often difficult to distinguish. Tracheobronchitis with pronounced secretion which can't be controlled otherwise can be an indication for antimicrobial therapy.There are no data available in order to establish a recommendation for the initial empiric calculated antimicrobial therapy in patients with home ventilation...

Patterns of genomic evolution between primary and metastatic breast cancer have not been studied in large numbers, despite patients with metastatic breast cancer having dismal survival. We sequenced whole genomes or a panel of 365 genes on 299 samples from 170 patients with locally relapsed or metastatic breast cancer. Several lines of analysis indicate that clones seeding metastasis or relapse disseminate late from primary tumors, but continue to acquire mutations, mostly accessing the same mutational processes active in the primary tumor...

In the last few decades, dye-sensitized solar cell (DSC) technology has been demonstrated to be a promising candidate for low cost energy production due to cost-effective materials and fabrication processes. Arguably, DSC stability is the biggest challenge for making this technology appealing for industrial exploitation. This work provides further insight into the stability of DSCs by considering specific dye-electrolyte systems characterized by Raman and impedance spectroscopy analysis. In particular, two ruthenium-based dyes, Z907 and Ru505, and two commercially available electrolytes, namely, the high stability electrolyte (HSE) and solvent-free Livion 12 (L-12), were tested...
