There were differences (false discovery rate, FDR 0.05) between the 2 genetic strains. Selenomonas bovis (12.6%) and Bacteroides plebeius (12.3%) were the top 2 predominant bacteria in the ceca of WB birds; however, the relative abundances of these 2 bacteria were only 5.1% and 1.2% in NB birds, respectively. Function analysis predicted that the metabolic activities differed (q less then 0.05) only between phenotypes. The microbiota of WB birds was characterized as reduced glycolysis and urea cycle but increased tricarboxylic acid (TCA) cycles, sugar degradation, and purine and pyrimidine nucleotides biosynthesis. Further studies are needed to investigate if WB incidence could be reduced by regulating gut microbiota and the potential mechanism that leads to decreased WB incidence.Nuclear magnetic resonance (NMR) has long been instrumental in the characterization of intrinsically disordered proteins (IDPs) and intrinsically disordered regions (IDRs). This method continues to offer rich insights into the nature of IDPs in solution, especially in combination with other biophysical methods such as small-angle scattering, single-molecule fluorescence, electron paramagnetic resonance (EPR), and mass spectrometry. Substantial advances have been made in recent years in studies of proteins containing both ordered and disordered domains and in the characterization of problematic sequences containing repeated tracts of a single or a few amino acids. These sequences are relevant to disease states such as Alzheimer's, Parkinson's, and Huntington's diseases, where disordered proteins misfold into harmful amyloid. Innovative applications of NMR are providing novel insights into mechanisms of protein aggregation and the complexity of IDP interactions with their targets. As a basis for understanding the solution structural ensembles, dynamic behavior, and functional mechanisms of IDPs and IDRs, NMR continues to prove invaluable.The SCN5A gene, located on chromosome 3p21, has 28 exons and is a member of the human voltage-gated sodium channel gene family. Genetic variation in SCN5A is associated with a diverse range of phenotypes. Due to incomplete penetrance, delayed expression, inherent low signal-to-noise ratio, and marked phenotypic heterogeneity, rare novel variants in SCN5A could be misinterpreted. Hence, defining the phenotypic characteristics of these rare SCN5A variants in humans is of importance. We describe the phenotypic heterogeneity noted in 4 familial carriers of a rare, previously unreported, large deletion in exon 20 of SCN5A (c.3667-?_c.3840C +?del) and discuss the mechanisms that underlie this heterogeneity.

To perform a systematic review on the research on the application of artificial intelligence (AI) to imaging published in Italy and identify its fields of application, methods and results.

A Pubmed search was conducted using terms Artificial Intelligence, Machine Learning, Deep learning, imaging, and Italy as affiliation, excluding reviews and papers outside time interval 2015-2020. In a second phase, participants of the working group AI4MP on Artificial Intelligence of the Italian Association of Physics in Medicine (AIFM) searched for papers on AI in imaging.

The Pubmed search produced 794 results. 168 studies were selected, of which 122 were from Pubmed search and 46 from the working group. The most used imaging modality was MRI (44%) followed by CT(12%) ad radiography/mammography (11%). The most common clinical indication were neurological diseases (29%) and diagnosis of cancer (25%). Classification was the most common task for AI (57%) followed by segmentation (16%). 65% of studies used machine learning and 35% used deep learning. We observed a rapid increase of research in Italy on artificial intelligence in the last 5years, peaking at 155% from 2018 to 2019.

We are witnessing an unprecedented interest in AI applied to imaging in Italy, in a diversity of fields and imaging techniques. Further initiatives are needed to build common frameworks and databases, collaborations among different types of institutions, and guidelines for research on AI.

Initial clinical manifestations of NMOSD may rarely overlap with MS. GI254023X in vivo Fingolimod may trigger severe attacks in patients with NMOSD previously misdiagnosed as MS. These cases are rare and their pathophysiology remains elusive.

We recruited all NMOSD patients treated by fingolimod in a single-center cohort of Afro-Caribbean neuro-inflammatory patients in Fort-de-France (French West Indies). Six patients were collected from the literature.

Among 622 patients followed locally for MS, 101 received fingolimod and two suffered severe attacks revealing a typical NMOSD presentation. These two patients were found to have AQP4-IgG. The risk of misdiagnosed NMOSD in MS in our high-risk Afro-Caribbean patients was estimated to be 1.9% (0 to 4.7%). Among the whole cohort, relapses occurred within a month after fingolimod initiation in five patients. All attacks were severe and contrasted with previously benign attacks, suggesting a shift to a more severe disorder. An unusual finding in these patients was large brain lesions.

AQP4-IgG should be obtained before initiation of fingolimod in high-risk patients, especially in those from areas of high NMOSD prevalence.

Currently, there is no pharmacotherapy approved for treating AMPH or other psychostimulant drug addiction. Different studies have shown promising properties of cannabidiol (CBD) for treating many neurological and psychiatric diseases, and recently, CBD is being considered a potential strategy for the treatment of drug addiction disorders. Thus, we investigated possible CBD beneficial effects on relapse symptoms following AMPH re-exposure considering drug relapse is the most difficult clinical factor to control during addiction treatment. Rats received d,l-AMPH (4 mg/kg, i.p.) or vehicle in the conditioned place preference (CPP) paradigm (8 days), when each experimental group was re-assigned to receive CBD at two different doses (5 or 10 mg/kg, i.p) or control, for 5 days. Subsequently, animals were re-exposed to AMPH-CPP (4 mg/kg, i.p.) for 3 additional days to assess relapse behavior.
