Observation of the moon shadow using a new reconstruction technique in the CLUE experiment
The CLUE experiment, located in La Palma island at 2200 m a.s.l., is an array of 3×3 telescope, detecting the UV
(190–230 nm) ˇCerenkov light produced by atmospheric showers. Due to the higher atmospheric absorption in the UV range than in the visible one, CLUE cannot apply existing algorithms normally used in IACT experiments to determine primary cosmic ray direction. In this paper we present a new method developed by CLUE. The algorithm performances were evaluated using simulated showers. CLUE experiment collected data in the last two years pointing to AGN sources and to Moon. The preliminary results obtained using the new technique on Crab Nebula and on Markarian 421 were presented in a previous paper. Here, we present the preliminary observation of Moon Shadow employing the new method. As described in the paper, we expect in a near future improvements on AGN sources and on Moon Shadow measurement

Poly(amidoamine) conjugated with disulphide linked cholesterol pendant self-assembling into redox-sensitive nanoparticles
Poly(amidoamine) (PAA) networks that are obtained by the use of cystamine as a cross-linking agent in the
reaction with 2,2\u2032-dithiodipyridine turn into linear PAAs with dithiopyridyl side groups that easily undergo an
exchange reaction with thiocholesterol. The resultant products represent the first examples of amphiphilic
PAA-cholesterol conjugates in which lipophilic cholesterol moieties are linked to the hydrophilic PAA chain by
S-S bonds that are stable in blood but cleavable inside cells. In aqueous media, these conjugates self-assemble
into nanoaggregates whose inner cores consist of lipophilic cholesterol domains. A series of PAA-cholesterol
conjugates that are derived from two different bis-acrylamides, namely 2,2-bis(acrylamido)acetic acid and 1,4-
bis(acryloyl)piperazine, and that have different cholesterol contents were obtained. All products were characterized
by 1H and 13C NMR spectroscopy, and the average molecular weights of the soluble polymers were determined
by size exclusion chromatography. In all instances, the segregation of cholesterol residues from the aqueous
medium was revealed by the comparison of their NMR spectra in CDCl3 and D2O, respectively. The TEM analysis
of the PAA-cholesterol aggregates in aqueous buffers revealed homogeneous round nanospheres whose dimensions and dimension distributions were determined by DLS. Preliminary cytocompatibility tests demonstrated that all prepared PAA-cholesterol samples are cytocompatible and thus show potential for biotechnological applications

Effect of enzyme inducing anticonvulsants on ethosuximide pharmacokinetics in epileptic patients
1To assess the effect of enzyme inducing anticonvulsants on ethosuximide pharmacokinetics, plasma ethosuximide concentrations after a single oral dose (500 mg) of the drug were compared in 12 healthy control subjects and 10 epileptic patients receiving chronic therapy with phenobarbitone, phenytoin and/or carbamazepine

Comorbidity prevalence and treatment outcome in children and adolescents with ADHD
Although ADHD comorbidity has been widely studied, some issues remain unsolved. This multicenter observational study aims to examine comorbid psychiatric disorders in a clinical sample of newly diagnosed, treatment na\uefve children and adolescents with and without ADHD and, to compare treatment efficacy based on the type of comorbidity. We performed an analysis of the medical records of patients identified from the Regional ADHD Registry database, enrolled in 18 ADHD centers in the 2011-2016 period. 1919 of 2861 subjects evaluated (67%) met the diagnostic criteria for ADHD: 650 (34%) had only ADHD, while 1269 (66%) had at least one comorbid psychiatric disorder (learning disorders, 56%; sleep disorders, 23%; oppositional defiant disorder, 20%; anxiety disorders, 12%). Patients with ADHD of combined type and with severe impairment (CGI-S 655) were more likely to present comorbidity. 382 of 724 (53%) followed up patients improved after 1\ua0year of treatment. ADHD with comorbidity showed greater improvement when treated with combined interventions or methylphenidate alone. Specifically, combined treatment showed significant superiority for ADHD with learning disorders (ES 0.66) and ODD (ES 0.98), lower for ADHD with sleep or anxiety disorders. Training intervention alone showed only medium efficacy (ES 0.50) for ADHD and learning disorders. This study was the first describing comorbidity patterns of ADHD in Italy, confirming, in a multicenter clinical setting, that ADHD is more often a complex disorder. Findings highlight important diagnostic, therapeutic, and service organization aspects that should be broadly extended to ensure an appropriate and homogenous ADHD management
