Periodic lateralized epileptiform discharges as manifestation of pneumococcal meningoencephalitis

Periodic Lateralized Epileptiform Discharges (PLEDs) are usually seen in the context of destructive structural lesions of the cortex, more frequently in acute ischemic stroke and less common in tumours and meningoencephalitis, specially herpes simplex virus. Its origin and prognosis are uncertain but it is known that PLEDs are linked to epilectic seizures, including status epilepticus

Density, structure and dynamics of water: the effect of Van der Waals interactions

It is known that ab initio molecular dynamics (AIMD) simulations of liquid water, based on the generalized gradient approximation (GGA) to density functional theory (DFT), yield structural and diffusive properties in reasonable agreement with experiment only if artificially high temperatures are used in the simulations. The equilibrium density, at normal conditions, of DFT water has been recently shown by Schmidt et al. [J. Phys. chem. B, 113, 11959 (2009)] to be underestimated by different GGA functionals for exchange and correlation, and corrected by the addition of interatomic pair potentials to describe van derWaals (vdW) interactions. In this contribution we present a DFTAIMD study of liquid water using several GGA functionals as well as the van der Waals density functional (vdW-DF) of Dion et al. [Phys. Rev. Lett. 92, 246401(2004)]. As expected, we find that the density of water is grossly underestimated by GGA functionals. When a vdW-DF is used, the density improves drastically and the experimental diffusivity is reproduced without the need of thermal corrections. We analyze the origin of the density differences between all the functionals. We show that the vdW-DF increases the population of non-H-bonded interstitial sites, at distances between the first and second coordination shells. However, it excessively weakens the H-bond network, collapsing the second coordination shell. This structural problem is partially associated to the choice of GGA exchange in the vdW-DF. We show that a different choice for the exchange functional is enough to achieve an overall improvement both in structure and diffusivity.Comment: 11 pages, 9 figures, submitted. Revised versio

The relationship between organizational commitment and intention to leave: A model of.

The aim of this article is to provide empirical evidence on two questions belonging to the research agenda of organizational commitment research: the possible existence of several facets of continuance commitment, and of non-linear relationships between organizational commitment and various organizational behaviors and their predictors, such as turnover and intention to leave the organization. An empirical research through a survey with 241 respondents has been carried out, and hypotheses have been tested through hierarchic linear regression. The results obtained confirm the relationship between affective commitment and intention to leave found in previous research, and the existence of two distinct components of continuance commitment. There have not been found non-linear relationships between organizational commitment and the intention to leave the organization. One of the most important managerial implications of this research is that in order to reduce turnover, human resource managers should foster affective and continuance organizational commitment among the employees.Organizational commitment; affective commitment; continuance commitment; work attitud

Héðinsdalsjökull, northern Iceland: geomorphology recording the recent complex evolution of a glacier

The objective of this work is to conduct a detailed mapping of the Héðinsdalsjökull foreland, northern Iceland (65°39′N, 18°55′W). This cirque currently shows a variety of glacial and periglacial landforms derived from a complex deglaciation. Mapping was performed combining traditional hand-drawn and digital mapping. A hand-drawn sketch was georeferenced in ArcMap 10.7.1, supported on an aerial photograph (year 2000). Its vectorization, symbolization and final design were done in the computer-aided design (CAD) software MicroStation Connect. Complementary high-resolution Digital Surface Models were obtained from historical aerial photographs and ground-view field photographs through the application of Structure from Motion (SfM) photogrammetry. To improve the topographic expression of the geomorphological map, a photorealistic 3D view has been generated. The final map highlights the complexity of the foreland and the coexistence existence of a range of different units and landforms. The map will ease future studies on the transformation of receding glaciers.info:eu-repo/semantics/publishedVersio

Publisher Copyright: © 2024 by the authors.Bimetallic nanomaterials have generated significant interest across diverse scientific disciplines, due to their unique and tunable properties arising from the synergistic combination of two distinct metallic elements. This study presents a novel approach for synthesizing branched gold–platinum nanoparticles by utilizing poly(allylamine hydrochloride) (PAH)-stabilized branched gold nanoparticles, with a localized surface plasmon resonance (LSPR) response of around 1000 nm, as a template for platinum deposition. This approach allows precise control over nanoparticle size, the LSPR band, and the branching degree at an ambient temperature, without the need for high temperatures or organic solvents. The resulting AuPt branched nanoparticles not only demonstrate optical activity but also enhanced catalytic properties. To evaluate their catalytic potential, we compared the enzymatic capabilities of gold and gold–platinum nanoparticles by examining their peroxidase-like activity in the oxidation of 3,3′,5,5′-tetramethylbenzidine (TMB). Our findings revealed that the incorporation of platinum onto the gold surface substantially enhanced the catalytic efficiency, highlighting the potential of these bimetallic nanoparticles in catalytic applications.publishersversionpublishe

Lived experiences and opinions of women of sub-Saharan origin on female genital mutilation: A phenomenological study

Aims and objectives: This study aimed to describe and understand the lived experi-ences and opinions of sub-Saharan women living in Spain in relation to female genital mutilation.Background: Female genital mutilation is a bloody procedure with serious conse-quences for the health of women and girls. Understanding mutilated women's lived experiences plays a crucial role in the management of health consequences and could help healthcare professionals to provide assistance to these women.Design: A descriptive phenomenological study was carried out. The COREQ checklist was followed as guidance to write the manuscript.Methods: A total of 12 in-depth interviews were conducted. Interviews were re-corded, transcribed and analysed using ATLAS.ti 9.0.Results: Two themes with four subthemes were identified from the data analysis: 1) ‘The traumatic experience of female circumcision’ with the subthemes ‘Female muti-lation is a physical and psychological torture procedure’ and ‘recognising and coping with negative emotions’; 2) ‘The fight for the eradication of female genital mutilation’ which contains the subthemes ‘the need for a real sociocultural change at the origin’ and ‘“I want to be the last”: Personal development leads to sociocultural change’.Conclusions: Female genital mutilation was experienced by women as a very aggres-sive and traumatic event. It causes considerable negative emotions that last over time. Although there is a tendency to reject the practice, in women's countries of origin, there is social pressure for girls to be mutilated.Relevance to clinical practice: Caring for women who have suffered from female genital mutilation requires awareness of the traumatic experience they underwent when they were girls. Healthcare professionals play a crucial role in eradicating female genital mutilation. Apart from education, preventive measures may include specific recommendations when girls are travelling to the country of origin and participatory action research
