Several studies suggest that genetic variants that influence the onset, maintenance and resolution of the immune response might be fundamental in predicting the evolution of COVID-19. In the present paper, we analysed the distribution of GM allotypes (the genetic markers of immunoglobulin γ chains) in symptomatic and asymptomatic COVID-19 patients and in healthy controls, all born and residing in Sicily. Indeed, the role played by GM allotypes in immune responses and infection control is well known. Our findings show that the GM23 allotype is significantly reduced in healthy controls. Interestingly, in a previous study, Sicilians carrying the GM23 allotype were associated with the risk of developing a symptomatic Human Cytomegalovirus infection. However, a note of caution should be considered, due to the small sample size of patients and controls.

Background: Intestinal cells receive incoming signals from neighboring cells and microbial communities. Upstream signaling pathways transduce these signals to reach transcription factors (TFs) that regulate gene expression. In inflammatory bowel disease (IBD), most single nucleotide polymorphisms (SNPs) are in non-coding genomic regions containing TF binding sites.

Disrupted gamma-aminobutyric acid (GABA) neurotransmission may contribute to the pathophysiology of schizophrenia. Reductions in hippocampal GABAergic neurons have been found in schizophrenia, and increased hippocampal perfusion has been described in schizophrenia and in people at clinical high-risk for psychosis (CHRp). We have also found decreases in hippocampal GABA receptors containing the α5 subunit (GABARα5) in a well-validated neurodevelopmental rat model of relevance for schizophrenia.

Introduction And Objectives: Obesity has been considered the pandemic of the 21st century due to its high prevalence and the significant morbidity and mortality it entails. The aim of this study is to assess the prevalence of obesity in two occupational sectors and to determine the variables associated with it.
Methodology: This is a cross-sectional and descriptive study involving 56,856 workers from the commerce and industrial sectors.

Objective: To compare brain activity before voluntary movement and before the same movement when it was released from suppression. This study examined the Bereitschaftspotential (BP) and beta band event-related desynchronization (bERD) during active blink suppression, contrasting these with voluntary blinking, where these EEG correlates of motor preparation are well-established.
Methods: Fifteen healthy adults performed voluntary blink and blink suppression-release tasks with EEG recording.

Background: Age-related declines in dynamic balance and cognitive control increase fall risk in older adults (OA). Non-invasive brain stimulation, such as anodal transcranial direct current stimulation (a-tDCS), may enhance training outcomes. However, it remains unclear whether stimulation over motor or prefrontal regions is more effective for improving dynamic balance training (DBT) in OA.
