Experience in real clinical practice with ceftazidime/avibactam is limited, and there are even fewer data on infections due to OXA-48-producing Enterobacteriaceae. We designed an observational study of a prospectively collected cohort of adult patients receiving ceftazidime/avibactam in our centre. Only the first treatment course of each patient was analysed. Efficacy and safety were evaluated as 14 and 30 day mortality, recurrence rate at 90 days, resistance development and occurrence of adverse ...

Abstract Aim The landscape of the Neotropical region has undergone dynamic evolution throughout the Miocene, with the extensive Pebas wetland occupying western Amazonia between 23 and c . 10 Ma and the continuous uplift of the Andes mountains. The complex interaction between the Andes and Amazonia probably influenced the trajectory of Neotropical biodiversity, but evidence from time‐calibrated phylogenies of groups that diversified during this period is lacking. We investigate the role of these landscape ...

The cost of obtaining large volumes of bridge data with technologies like laser scanners hinders the training of deep learning models. To address this, this paper introduces a new method for creating synthetic point clouds of truss bridges and demonstrates the effectiveness of a deep learning approach for semantic and instance segmentation of these point clouds. The method generates point clouds by specifying the dimensions and components of the bridge, resulting in high variability in the generated ...

Several methods have been developed for the semantic segmentation of reinforced concrete bridges, however, there is a gap for truss bridges. Therefore, in this study a state-of-the-art methodology for the instance and semantic segmentation of point clouds of truss bridges for modelling purposes is presented, which, to the best of the authors' knowledge, is the first such methodology. This algorithm segments each truss element and classifies them as a chord, diagonal, vertical post, interior lateral ...

Lidocaine is a commonly used local anaesthetic that, besides blocking voltage-dependent Na(+) channels, has multiple inhibitory effects on muscle-type nicotinic acetylcholine (ACh) receptors (nAChRs). In the present study, we have investigated the effects of lidocaine on ACh-elicited currents (IAChs) from cultured mouse superior cervical ganglion (SCG) neurons, which mainly express heteromeric α3β4 nAChRs. Neurons were voltage-clamped by using the perforated-patch method and IAChs were elicited by fast ...

Background: In recent years, several scores and algorithms have been developed in order to guide empirical antibiotic treatment in patients with gram-negative bacilli (GNB) bacteraemia according to the risk of extended-spectrum β-lactamase (BL) producing. Some of these algorithms do not have easy applicability or present some limitations in their validation. The aim of our study was to validate a recently designed decision tree in our prospective cohort of bacteraemia due to gram-negative bacilli. ...

Abstract The male genitalic characters of Hexapoda are well known for their great taxonomic and systematic value. Despite insect male genitalia displaying large diversity, variation, and modification across orders, some structures are consistently present, and such characters can serve as the basis for discussion regarding homology. In the order Lepidoptera, a male genitalic structure widely known as the ‘juxta’ is present in many taxa and absence or modification of this character can be phylogenetically ...

The insulin-like growth factor II (IGF-II) is involved in embryonic growth. Modifications of its expression might play a role in the development of primary liver cancer in humans and woodchucks. In the liver, little information is available on the cell types involved in its synthesis. We have investigated the expression of IGF-II as well as IGF-II, IGF-I and insulin receptor mRNAs in non parenchymal liver cell preparations in rats of various ages. The results indicate that Kupffer cells, endothelial ...

It has reported that many environmental compounds may display estrogenic actions and these findings led to researchers to associate breast cancer risk with the use of some pesticides. The aim of this work was to investigate the effect of chlorpyrifos (CPF) on cell proliferation and the ERα-dependence of this action employing MCF-7 and MDA-MB-231 breast cancer cell lines. We have also analyzed CPF action on the cell cycle distribution and the cyclins that are implicated in G1-S and intra-S checkpoints. ...

Euptychia saltuensis Hayward, 1962, new synonym, currently regarded as a nomen dubium and possibly a junior subjective synonym of Yphthimoides manasses (C. Felder & R. Felder, 1867), is here treated as a junior subjective synonym of Yphthimoides patricia (Hayward, 1957), based on morphological characters of the male genitalia and the DNA barcode. The taxonomic status of Y. patricia is re-examined, and a detailed redescription of the adult morphology, including the male genitalia, is presented. Information ...

In this work, we report on the evaluation of a superconducting fault current limiter (SFCL). It is consisted of a modular superconducting device combined with a short-circuited transformer with a primary copper winding connected in series to the power line and the secondary side short-circuited by the superconducting device. The basic idea is adding a magnetic component to contribute to the current limitation by the impedance reflected to the line after transition of the superconducting device. The ...
