InfoFaunaFVG: a novel progressive web application for wildlife surveillance
The Department of Agricultural, Food, Environmental and Animal Sciences (DI4A) at the University of Udine, in collaboration with Friuli Venezia Giulia regional authorities, within northeastern Italy, set up a wildlife monitoring and surveillance regional network, named InfoFaunaFVG. Here we describe the development and application of this data repository system based on a novel progressive web application, and report the data gathered in the first two and a half years of its use. InfoFaunaFVG is made of a Web Database and an integrated WebGIS system. In particular, the following open source softwares are used: Apache HTTP Server, Oracle MySQL, Symfony, Apache Tomcat, GeoServer, OpenLayers. The web app can be accessed from any web browser or by installing the progressive web application in the desktop or mobile devices. In short, operating from November 2019, InfoFaunaFVG currently (April 2022) contains a total of 40,175 records, from 300 different users, from 16 institutions. Among all species recorded, mammals were 40% (16,018) of the total, whereas avian species represented 59% (23,741), and others (reptiles and amphibians) 1% (416), respectively. Two hundred twenty-six different species (175 avian and 51 mammals) were recorded. Details about causes of death and live animal rescue were reported. To date, InfoFaunaFVG has proven to be a successful wildlife data repository system providing high quality consistent, accurate and traceable data. These had a considerable impact on regional wildlife governance. In the authorsâ knowledge, InfoFaunaFVG is the first example described in literature of such a progressive web application, coordinated on an institutional level, and not based on voluntary-citizen observations. InfoFaunaFVG has the potential to become the largest wildlife monitoring and surveillance data repository system on a national level
The effects of the ketogenic diet in refractory partial seizures with reference to tuberous sclerosis.
Valproic acid and phenobarbital blood levels during the first month of treatment with the ketogenic diet.
Objective â The aim of this study was to assess how the ketogenic diet
influences the blood levels of antiepileptic drugs in the first month of
treatment in a pediatric population with drug-resistant epilepsy. Methods
â The plasma concentrations of antiepileptic drugs were investigated in
an open study on 36 consecutive children and adolescents (20 males),
aged between 6 months and 16 years (mean age 4.7 years), who were
put on the ketogenic diet because of medically refractory epilepsy. The
plasma levels of antiepileptic drugs were determined 30 days and
immediately before the diet and on days 8, 15, 22 and 29 after the start
of the diet. The daily dose of each drug was not changed during the
first month of treatment, while the daily dose of benzodiazepines was
reduced by up to 30% if excessive sedation or drowsiness
occurred. Results â While plasma concentrations of phenobarbital did
not change in the first month on the ketogenic diet (mean increase of
2.3 mg â l 1.0), valproic acid showed a slight but not significant
decrease (mean decresase of 6.7 mg â l 3.2), 2 weeks after the start of
the diet. Conclusions â Adjustments in the daily dose of either drug
before the start of the diet do not however appear to be justified
Morphological and Chemical Investigation of Ovarian Structures in a Bovine Model by Contrast-Enhanced X-ray Imaging and Microscopy
An improved understanding of an ovaryâs structures is highly desirable to support advances in folliculogenesis knowledge and reproductive medicine, with particular attention to fertility preservation options for prepubertal girls with malignant tumors. Although currently the golden standard for structural analysis is provided by combining histological sections, staining, and visible 2D microscopic inspection, synchrotron radiation phase-contrast microtomography is becoming a new challenge for three-dimensional studies at micrometric resolution. To this aim, the proper use of contrast agents can improve the visualization of internal structures in ovary tissues, which normally present a low radiopacity. In this study, we report a comparison of four staining protocols, based on iodine or tungsten containing agents, applied to bovine ovarian tissues fixed in Bouinâs solution. The microtomography (microCT) analyses at two synchrotron facilities under different set-ups were performed at different energies in order to maximize the image contrast. While tungsten-based agents allow large structures to be well identified, Iodine ones better highlight smaller features, especially when acquired above the K-edge energy of the specific metal. Further scans performed at lower energy where the setup was optimized for overall quality and sensitivity from phase-contrast still provided highly resolved visualization of follicular and intrafollicular structures at different maturation stages, independent of the staining protocol. The analyses were complemented by X-ray Fluorescence mapping on 2D sections, showing that the tungsten-based agent has a higher penetration in this type of tissues
Rufinamide in refractory childhood epileptic encephalopathies other than Lennox-Gastaut syndrome.
Background: To report on the first multicenter Italian experience with rufinamide as
adjunctive drug in children, adolescents and young adults with refractory childhoodonset
epileptic encephalopathies other than LennoxâGastaut syndrome.
Methods: Thirty-eight patients (19 males, 19 females), aged between 4 and 34 (mean
13.7 ± 8.3, median 12.5), all affected by different types of childhood-onset refractory
epileptic encephalopathies other than LennoxâGastaut syndrome, were treated with
rufinamide as adjunctive drug for a mean period of 11.4 months (range 3â26 months).
Results: Fifteen of 38 patients (39.5%) had a âĄ50% seizure reduction in countable
seizures. Complete seizure freedom was achieved in one of these patients (2.6%).
Three patients (7.9%) had a 25â49% seizure reduction, whilst seizure frequency
remained unchanged in 15 (39.5%) and increased in five patients (13.1%). Eleven
patients (28.9%) reported adverse side effects. Vomiting was reported in five patients
(13.1%); drowsiness, decreased appetite and irritability with migraine manifested in
other four patients. They were transient and mild in all cases.
Conclusion: Rufinamide may be an effective and well-tolerated adjunctive drug for
the treatment of refractory childhood-onset epileptic encephalopathies other than
LennoxâGastaut syndrome. Rufinamide was most effective in patients with dropattacks
and (bi)frontal spikeâwave discharges.
Introduction
Rufinamide is a structurally triazole-derivative (1-[2,6-
difluorophenyl)methyl]-1hydro-1,2,3-triazole-carboxamide)
novel antiepileptic drug, structurally unrelated to
the existing antiepileptic drugs, and approved by the
Food and Drug Administration for the treatment of
LennoxâGastaut syndrome in patients aged 4 and over,
and for the treatment of partial seizures in adults and
adolescents.
The proposed mechanism of action is the limitation

Candidate biomarkers from the integration of methylation and gene expression in discordant autistic sibling pairs
While the genetics of autism spectrum disorders (ASD) has been intensively studied, resulting in the identification of over 100 putative risk genes, the epigenetics of ASD has received less attention, and results have been inconsistent across studies. We aimed to investigate the contribution of DNA methylation (DNAm) to the risk of ASD and identify candidate biomarkers arising from the interaction of epigenetic mechanisms with genotype, gene expression, and cellular proportions. We performed DNAm differential analysis using whole blood samples from 75 discordant sibling pairs of the Italian Autism Network collection and estimated their cellular composition. We studied the correlation between DNAm and gene expression accounting for the potential effects of different genotypes on DNAm. We showed that the proportion of NK cells was significantly reduced in ASD siblings suggesting an imbalance in their immune system. We identified differentially methylated regions (DMRs) involved in neurogenesis and synaptic organization. Among candidate loci for ASD, we detected a DMR mapping to CLEC11A (neighboring SHANK1) where DNAm and gene expression were significantly and negatively correlated, independently from genotype effects. As reported in previous studies, we confirmed the involvement of immune functions in the pathophysiology of ASD. Notwithstanding the complexity of the disorder, suitable biomarkers such as CLEC11A and its neighbor SHANK1 can be discovered using integrative analyses even with peripheral tissues

Encephalomyocarditis virus infection in an Italian zoo
A fatal Encephalomyocarditis virus (EMCV) infection epidemic involving fifteen primates occurred between October 2006 and February 2007 at the Natura Viva Zoo. This large open-field zoo park located near Lake Garda in Northern Italy hosts one thousand animals belonging to one hundred and fifty different species, including various lemur species. This lemur collection is the most relevant and rich in Italy. A second outbreak between September and November 2008 involved three lemurs. In all cases, the clinical signs were sudden deaths generally without any evident symptoms or only with mild unspecific clinical signs. Gross pathologic changes were characterized by myocarditis (diffuse or focal pallor of the myocardium), pulmonary congestion, emphysema, oedema and thoracic fluid. The EMCV was isolated and recognized as the causative agent of both outbreaks. The first outbreak in particular was associated with a rodent plague, confirming that rats are an important risk factor for the occurrence of the EMCV infection
