Patterned functional network disruption in amyotrophic lateral sclerosis
2019
Abstract Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease primarily affecting motor function, with additional evidence of extensive nonmotor involvement. Despite increasing recognition of the disease as a multisystem network disorder characterised by impaired connectivity, the precise neuroelectric characteristics of impaired cortical communication remain to be fully elucidated. Here, we characterise changes in functional connectivity using beamformer source analysis on resting‐state electroencephalography recordings from 74 ALS patients and 47 age‐matched healthy controls. Spatiospectral characteristics of network changes in the ALS patient group were quantifi…
Molecular Electron Density Theory: A Modern View of Reactivity in Organic Chemistry
2016
A new theory for the study of the reactivity in Organic Chemistry, named Molecular Electron Density Theory (MEDT), is proposed herein. MEDT is based on the idea that while the electron density distribution at the ground state is responsible for physical and chemical molecular properties, as proposed by the Density Functional Theory (DFT), the capability for changes in electron density is responsible for molecular reactivity. Within MEDT, the reactivity in Organic Chemistry is studied through a rigorous quantum chemical analysis of the changes of the electron density as well as the energies associated with these changes along the reaction path in order to understand experimental outcomes. St…
La diffusion des NTIC au sein du réseau urbain français et le rôle des acteurs publics
2001
The study deals with the ways in which the general public and the government make use of new information and communication technologies. We analyze the physical locations of Internet sites with “fr” as their domain names. The data were provided by the French NIC center (AFNIC). Using this sample (a quarter of all French sites), we find a rather even distribution of French sites in the Paris area plus the other main French cities, and the remainder of France. In addition, we try to enumerate the initiatives of the public actors responsible for the regional planning of the new information and communication technologies. Firstly, we clarify the economic and legal framework in which public acto…
Les modernes religioses valencianes: entrebancs d’una recerca textual
2013
Resum: El catàleg titulat Lletraferides modernes. Catàleg de les escriptores valencianes dels segles XVI-XVIII (Herrero 2009) suposava un punt de partida en la compilació de «lletraferides» valencianes de l’Edat Moderna. Aquest ajudà a rescatar els seus noms, però el major handicap radica en la diversitat en la localització física dels textos. A través d’una visió dels diferents gèneres que empraren aquestes escriptores, en especial les religioses (poesia, mística, auto/biografia espiritual…), avancem algunes conclusions que permetran una anàlisi sociolingu?ística, literària i de gènere d’eixes obres.Paraules clau: Catàleg, Localizació textual, Autores religioses, Valencianes, Modernes.Abs…
Exploring translation strategies in video game localization
2012
This paper addresses the issue of video game localisation focusing on the different strategies to be used from the point of view of Translation Studies. More precisely, the article explores the possible relation between the translation approaches used in the field and the different genres or textual typologies of video games. As the narrative techniques and the story lines of video games have become more complex and well-developed, the adaptation of games entails a serious challenge for translators. Video games have evolved into multimodal and multidimensional products and new approaches and insights are required when studying the adaptation of games into different cultures. Electronic ente…
Dysfunction of attention switching networks in amyotrophic lateral sclerosis
2019
Objective To localise and characterise changes in cognitive networks in Amyotrophic Lateral Sclerosis (ALS) using source analysis of mismatch negativity (MMN) waveforms. Rationale The MMN waveform has an increased average delay in ALS. MMN has been attributed to change detection and involuntary attention switching. This therefore indicates pathological impairment of the neural network components which generate these functions. Source localisation can mitigate the poor spatial resolution of sensor-level EEG analysis by associating the sensor-level signals to the contributing brain sources. The functional activity in each generating source can therefore be individually measured and investigat…
Co-localisation of hypoxia and perfusion markers with parameters of glucose metabolism in human squamous cell carcinoma (hSCC) xenografts
2009
Purpose: To examine relationships between tumour hypoxia, perfusion and metabolic microenvironment at themicroregional level in three different human squamous cell carcinomas (hSCC). Materials and methods: Nude mice bearing FaDu, UT-SCC-15, and UT-SCC-5 hSCC were injected with pimonidazole hypoxia and Hoechst perfusion markers. Bioluminescence imaging was used to determine spatial distribution of glucose and lactate content in serial tumour sections. Metabolite levels were grouped in 10 concentration ranges. Images were co-registered and at each concentration range the proportion of area stained for pimonidazole and Hoechst was determinedin 1113 tumours per tumour line. Results: The spatia…
A Molecular Electron Density Theory Study of the Reactivity of Azomethine Imine in [3+2] Cycloaddition Reactions
2017
The electronic structure and the participation of the simplest azomethine imine (AI) in [3+2] cycloaddition (32CA) reactions have been analysed within the Molecular Electron Density Theory (MEDT) using DFT calculations at the MPWB1K/6-311G(d) level. Electron localisation function (ELF) topological analysis reveals that AI has a pseudoradical structure, while the conceptual DFT reactivity indices characterise this TAC as a moderate electrophile and a good nucleophile. The non-polar 32CA reaction of AI with ethylene takes place through a one-step mechanism with low activation energy, 5.3 kcal/mol-1. A bonding evolution theory (BET) study indicates that this reaction takes place through a non-…
DIFFERENT LOCATIONS OF ENDOMETRIOSIS IN 86 PATIENTS: A SINGLE- CENTRE STUDY.
2015
Endometriosis is an important gynecologic disorder defined as the presence of functional endometrial glands and stroma outside the uterine cavity. Prevalence of endometriosis is 6-10% in the general population, but rises to 35-50% in women with pelvic pain or infertility or both. The aim of this study was to retrospectively review the different locations of pelvic and extrapelvic endometriosis occurred in our Department during last 3 years.
Patterns of oncogene co-expression at single cell resolution in cancer influence survival
2020
AbstractBackgroundCancers often overexpress multiple clinically relevant oncogenes. However, it is not known if multiple oncogenes within a cancer combine uniquely in specific cellular sub-populations to influence clinical outcome. We studied this phenomenon using the prognostically relevant oncogenes MYC, BCL2 and BCL6 in Diffuse Large B-Cell Lymphoma (DLBCL).MethodsQuantitative multispectral imaging simultaneously measured oncogene co-expression at single-cell resolution in reactive lymphoid tissue (n=12) and four independent cohorts (n=409) of DLBCL. Mathematically derived co-expression phenotypes were evaluated in DLBCLs with immunohistochemistry (n=316) and eight DLBCL cohorts with gen…
