Editorial: epilepsy and neurodevelopmental diseases
The association between epilepsy and neurodevelopmental diseases is well-recognized and has gained significant attention in the field of neuroscience in recent years. One of the main reasons for this interest is the need for a better understanding of the events that lead to the development and maturation of the CNS. This is a fundamental and necessary basis for potential breakthrough strategies that could guide novel and more effective disease-modifying therapeutic approaches to neurodevelopmental syndromes that are frequently characterized by severe and
drug-resistant epilepsy. The perspective of such new therapeutic strategies is very promising. At the state-of-theart, patients afflicted by these rare neurodevelopmental disorders mostly rely on “symptomatic” approaches that mitigate seizures and other major symptoms but do not target the underlying biological causes of the disease.
The study of this vast field of research is extremely complex and requires a multidisciplinary approach, from neuropathological to molecular and functional studies since even “simple” triggering events (e.g., a genetic mutation) during critical periods of brain development can lead to widespread effects on brain morphological and functional features
Self-Reported Long COVID in the General Population: Sociodemographic and Health Correlates in a Cross-National Sample.
We aimed to gain knowledge of possible sociodemographic predictors of long COVID and whether long COVID was associated with health outcomes almost two years after the pandemic outbreak. There were 1649 adults who participated in the study by completing a cross-sectional online survey disseminated openly in Norway, the UK, the USA, and Australia between November 2021 and January 2022. Participants were defined as having long COVID based on self-reports that they had been infected by COVID-19 and were experiencing long-lasting COVID symptoms. Logistic regression analyses were used to examine possible sociodemographic predictors, and multivariate analysis of variance was used to examine whether long COVID status was associated with health outcomes. None of the sociodemographic variables was significantly associated with reporting long COVID. Having long COVID was associated with higher levels of psychological distress, fatigue, and perceived stress. The effect of long COVID on health outcomes was greater among men than among women. In conclusion, long COVID appeared across sociodemographic groups. People with long COVID reported worsened health outcomes compared to those who had had COVID-19 but without long-term symptoms. Men experiencing long COVID appear to be particularly vulnerable to experiencing poorer health outcomes; health services may pay extra attention to potentially unnoticed needs for support among men experiencing long COVID
Phytocannabinoids in Neurological Diseases:Could They Restore a Physiological GABAergic Transmission?
Kolmogorov-Sinai entropy in field line diffusion by anisotropic magnetic turbulence
The Kolmogorov-Sinai (KS) entropy in turbulent diffusion of magnetic field
lines is analyzed on the basis of a numerical simulation model and theoretical
investigations. In the parameter range of strongly anisotropic magnetic
turbulence the KS entropy is shown to deviate considerably from the earlier
predicted scaling relations [Rev. Mod. Phys. {\bf 64}, 961 (1992)]. In
particular, a slowing down logarithmic behavior versus the so-called Kubo
number (, where is the ratio of the rms magnetic fluctuation field to the magnetic field
strength, and and are the correlation lengths in respective
dimensions) is found instead of a power-law dependence. These discrepancies are
explained from general principles of Hamiltonian dynamics. We discuss the
implication of Hamiltonian properties in governing the paradigmatic
"percolation" transport, characterized by , associating it with the
concept of pseudochaos (random non-chaotic dynamics with zero Lyapunov
exponents). Applications of this study pertain to both fusion and astrophysical
plasma and by mathematical analogy to problems outside the plasma physics.
This research article is dedicated to the memory of Professor George M.

Advanced mortar coatings for cultural heritage protection : Durability towards prolonged UV and outdoor exposure
In the present work, two kinds of hybrid polymeric\u2013inorganic coatings containing TiO2 or SiO2 particles and prepared starting from two commercial resins (Alpha\uaeSI30 and Bluesil\uaeBP9710) were developed and applied to two kinds of mortars (an air-hardening calcic lime mortar [ALM] and a natural hydraulic lime mortar [HLM]) to achieve better performances in terms of water repellence and consequently damage resistance. The two pure commercial resins were also applied for comparison purposes. Properties of the coated materials and their performance were studied using different techniques such as contact angle measurements, capillary absorption test, mercury intrusion porosimetry, surface free energy, colorimetric measurements and water vapour permeability tests. Tests were also performed to determine the weathering effects on both the commercial and the hybrid coatings in order to study their durability. Thus, exposures to UV radiation, to UV radiation/condensed water cycles and to a real polluted atmospheric environment have been performed. The effectiveness of the hybrid SiO2 based coating was demonstrated, especially in the case of the HLM mortar
Archaeometric approach for the study of mortars from the underwater archaeological site of Baia (Naples) Italy: Preliminary results
This work was aimed to evaluate the features of mortar samples taken from the underwater
archaeological area of Baia (Naples, Italy), an important site, where the remains of the
ancient Roman city of Baiae and Portus Iulius are submerged after bradyseism events, started
from 4th century AD. Several architectural structures are still preserved into the submerged
environment, such as: luxurious maritime villas, imperial buildings, private houses, thermae,
tabernae and warehouses. In particular, some samples were collected from the masonry walls
belonging to a building of the underwater area called Villa a Protiro. A first archaeometric
approach has been applied to analyse twelve archaeological mortars samples in order to define:
textural features, chemical composition and raw materials used for their production. For
this purpose different analytical methods were used, such as, polarizing optical microscope
(POM) and scanning electron microscopy (SEM-EDS).This work was financially supported by
national national research project “COMAS”
(Planned COnservation, “in situ”, of underwater
archaeological artifacts), funded by the Italian
Ministry of Education, Universities and
Research (MIUR).Peer reviewe
