Effects of Transcranial Direct Current Stimulation on Baseline and Slope of Prefrontal Cortex Hemodynamics During a Spatial Working Memory Task
2020
Background: Transcranial direct current stimulation (tDCS) has been shown to be an inexpensive, safe, and effective way of augmenting a variety of cognitive abilities. Relatively recent advances in neuroimaging technology have provided the ability to measure brain activity concurrently during active brain stimulation rather than after stimulation. The effects on brain activity elicited by tDCS during active tDCS reported by initial studies have been somewhat conflicted and seemingly dependent on whether a behavioral improvement was observed. Objective: The current study set out to address questions regarding behavioral change, within and between-participant designs as well as differentiatin…
Mobile phone use before and during the COVID-19 pandemic : a panel study of older adults in seven countries
2023
The aim of this study was to investigate the changes in older adults’ mobile phone use from before to during the COVID-19 pandemic. The media displacement and digital divide approaches served as the theoretical frameworks of the study. The data were drawn from the 2018 and 2020 waves of the Aging + Communication + Technology cross-national longitudinal panel study. The sample consisted of older Internet users, aged 62 to 96 (in 2018), from Austria, Canada, Finland, Israel, the Netherlands, Romania, and Spain, who participated in both waves (N = 4,398). Latent class analysis and latent transition analysis with multinomial regression models were the main methods applied to the data. With rega…
Social features, Spatial features, Time features: An urban archaeological data model
2007
http://proceedings.caaconference.org/files/2007/64_Rodier_Saligny_CAA2007.pdf; International audience; The use of GIS to study the spatial evolution of pre-industrial cities over the "longue durée" requires rigorous formalisation of heterogeneous data from different sources into robust entities. An initial model using the HBDS (Hypergraph Based Data Structure) method enabled us to distinguish social and spatial features. In this paper, we develop a specific model for the temporal dimension. The definition of urban objects using social, spatial and temporal features enhances the study of urban dynamics and of change over the "longue durée".
The Role of Fc Receptors on the Effectiveness of Therapeutic Monoclonal Antibodies.
2021
Since the approval of the first monoclonal antibody (mAb) in 1986, a huge effort has been made to guarantee safety and efficacy of therapeutic mAbs. As of July 2021, 118 mAbs are approved for the European market for a broad range of clinical indications. In order to ensure clinical efficacy and safety aspects, (pre-)clinical experimental approaches evaluate the respective modes of action (MoA). In addition to antigen-specificity including binding affinity and -avidity, MoA comprise Fc-mediated effector functions such as antibody dependent cellular cytotoxicity (ADCC) and the closely related antibody dependent cellular phagocytosis (ADCP). For this reason, a variety of cell-based assays have…
Structural and functional salivary disorders in type 2 diabetic patients
2006
La diabetes mellitus tipo 2 es el desorden metabólico más frecuente, siendo además causante de una importante morbi-mortalidad. En estos pacientes se han descrito alteraciones estructurales de la parotida (sialosis) que podrían comportar modificaciones en la composición salivar, así como un incremento de patología dental y periodontal. Objetivos: establecer las alteraciones bioquímicas de la saliva y su posible correlación con los hallazgos morfológicos. Diseño del estudio: se realizo un estudio clínico de 33 pacientes, 17 de ellos con diabetes tipo 2. Se recogieron muestras de saliva para análisis bioquímico y suero para control metabólico. Resultados: en la saliva de los pacientes diabéti…
Realizacja funkcji kapłańskiej w małżeństwie sakramentalnym
2019
Małżeństwo sakramentalne dzięki włączeniu w misterium paschalne Chrystusa uczestniczy w dziele zbawczym Kościoła powszechnego, realizując funkcję prorocką, kapłańską i królewską. Przedmiotem artykułu jest funkcja kapłańska realizowana przez małżonków dzięki Eucharystii, sakramentowi pokuty i nawrócenia oraz modlitwie. Uświęcenie małżonków, ich rodzin, Kościoła i całego świata dokonuje się poprzez ich sakramentalne wszczepienie w mękę, śmierć krzyżową i zmartwychwstanie Jezusa. Sprawowanie funkcji kapłańskiej w małżeństwie – co do swej istoty – jest powiązane ze zdolnością do składania duchowych ofiar dnia codziennego. Taka dyspozycja jest oznaką dojrzałości osobowej i religijnej. Świadome r…
Enhancing Light Emission in Interface Engineered Spin-OLEDs through Spin-Polarized Injection at High Voltages
2019
The quest for a spin-polarized organic light-emitting diode (spin-OLED) is a common goal in the emerging fields of molecular electronics and spintronics. In this device, two ferromagnetic (FM) electrodes are used to enhance the electroluminescence intensity of the OLED through a magnetic control of the spin polarization of the injected carriers. The major difficulty is that the driving voltage of an OLED device exceeds a few volts, while spin injection in organic materials is only efficient at low voltages. The fabrication of a spin-OLED that uses a conjugated polymer as bipolar spin collector layer and ferromagnetic electrodes is reported here. Through a careful engineering of the organic/…
Functional Extrapolations to Tame Unbound Anions in Density-Functional Theory Calculations
2019
Standard flavors of density-functional theory (DFT) calculations are known to fail in describing anions, due to large self-interaction errors. The problem may be circumvented using localized basis sets of reduced size, leaving no variational flexibility for the extra electron to delocalize. Alternatively, a recent approach exploiting DFT evaluations of total energies on electronic densities optimized at the Hartree-Fock (HF) level has been reported, showing that the self-interaction-free HF densities are able to lead to an improved description of the additional electron, returning affinities in close agreement with the experiments. Nonetheless, such an approach can fail when the HF densitie…
Effects of assisted training with neurofeedback on EEG measures, executive function and mood in a healthy sample
2015
The training in neurofeedback (NF) consists of teaching individuals to modify, adjust and enhance their brain activity pattern. The aim of our research was to evaluate the effect of training on cognitive processes, specifically executive function, and mood in a non-clinical sample. A sample of 30 female college students were assigned to three groups: RH: right hemisphere (n = 10), LH: left hemisphere (n = 10) and control (n = 10). The dominance pattern of beta and the inhibition of the theta pattern were trained in a single session. Measures of executive function (Iowa Gambling Test) and questionnaires of mood were taken pre and post training. We found that NF training produced significant …
