TL;DR: In girls, prevalence estimates increased significantly with age; furthermore, living with a single parent, low level of maternal education, and low family income were associated with a higher likelihood of suffering from emotional or behavioral problems.
Abstract: While in the last 5 years several studies have been conducted in Italy on the prevalence of mental disorders in adults, to date no epidemiological study has been targeted on mental disorders in adolescents. A two-phase study was conducted on 3,418 participants using the child behavior checklist/6–18 (CBCL) and the development and well-being assessment (DAWBA), a structured interview with verbatim reports reviewed by clinicians. The prevalence of CBCL caseness and DSM-IV disorders was 9.8% (CI 8.8–10.8%) and 8.2% (CI 4.2–12.3%), respectively. DSM-IV Emotional disorders were more frequently observed (6.5% CI 2.2–10.8%) than externalizing disorders (1.2% CI 0.2–2.3%). In girls, prevalence estimates increased significantly with age; furthermore, living with a single parent, low level of maternal education, and low family income were associated with a higher likelihood of suffering from emotional or behavioral problems. Approximately one in ten adolescents has psychological problems. Teachers and clinicians should focus on boys and girls living with a single parent and/or in disadvantaged socioeconomic conditions.

TL;DR: Introduction of two methyl groups at positions 3 and 5 of the phenyl ring of 2 furnished derivatives showed very potent and selective anti-HIV-1 activity not only against the wt strain, but also against mutants carrying NNRTI-resistant mutations at positions 103 and 181 of the reverse transcriptase gene.
Abstract: The potent anti-HIV-1 activities of L-737,126 (2) and PAS sulfones prompted us to design and test against HIV-1 in acutely infected MT-4 cells a number of novel 1- and 3-benzenesulfonylindoles. Indoles belonging to the 1-benzenesulfonyl series were found poorly or totally inactive. On the contrary, some of the 3-benzenesulfonyl derivatives turned out to be as potent as 2, being endowed with potencies in the low nanomolar concentration range. In particular, (2-methylphenyl)sulfonyl (72) and (3-methylphenyl)sulfonyl (73) derivatives showed EC(50) values of 1 nM. Introduction of two methyl groups at positions 3 and 5 of the phenyl ring of 2 furnished derivatives (80 and 83) which showed very potent and selective anti-HIV-1 activity not only against the wt strain, but also against mutants carrying NNRTI-resistant mutations at positions 103 and 181 of the reverse transcriptase gene.

TL;DR: The data suggest a mechanistic link between hyperactivation of the innate immune system and chronic airway inflammation and indicate IRAK-M as a potential target for therapeutic intervention against asthma.
Abstract: Asthma is a multifactorial disease influenced by genetic and environmental factors In the past decade, several loci and >100 genes have been found to be associated with the disease in at least one population Among these loci, region 12q13-24 has been implicated in asthma etiology in multiple populations, suggesting that it harbors one or more asthma susceptibility genes We performed linkage and association analyses by transmission/disequilibrium test and case-control analysis in the candidate region 12q13-24, using the Sardinian founder population, in which limited heterogeneity of pathogenetic alleles for monogenic and complex disorders as well as of environmental conditions should facilitate the study of multifactorial traits We analyzed our cohort, using a cutoff age of 13 years at asthma onset, and detected significant linkage to a portion of 12q13-24 We identified IRAK-M as the gene contributing to the linkage and showed that it is associated with early-onset persistent asthma We defined protective and predisposing SNP haplotypes and replicated associations in an outbred Italian population Sequence analysis in patients found mutations, including inactivating lesions, in the IRAK-M coding region Immunohistochemistry of lung biopsies showed that IRAK-M is highly expressed in epithelial cells We report that IRAK-M is involved in the pathogenesis of early-onset persistent asthma IRAK-M, a negative regulator of the Toll-like receptor/IL-1R pathways, is a master regulator of NF-κB and inflammation Our data suggest a mechanistic link between hyperactivation of the innate immune system and chronic airway inflammation and indicate IRAK-M as a potential target for therapeutic intervention against asthma

TL;DR: The results suggest that endogenous adenosine acting on A2a receptors can exert an inhibitory influence on the functional expression of D1‐mediated responses in dopamine‐denervated rats, and propose new possible therapeutic approaches in the treatment of Parkinson's disease.
Abstract: In rats with unilateral 6-hydroxydopamine lesions of the dopaminergic nigrostriatal pathway, administration of the A2a adenosine antagonist SCH 58261 alone did not induce any motor asymmetry but strongly potentiated the contralateral turning behaviour induced by the dopamine D1 agonist SKF 38393. SCH 58261 also increased the number of Fos-like positive nuclei induced by SKF 38393 in the 6-hydroxydopamine-lesioned striatum. Intense potentiation of D1-dependent turning behaviour and c-Fos expression was also observed after administration of the A2a/A1 antagonist CGS 15943. Administration of the A1 adenosine receptor antagonist DPCPX induced a small potentiation of D1-mediated contralateral turning while c-Fos expression induced by SKF 38393 was not modified. The results suggest that endogenous adenosine acting on A2a receptors can exert an inhibitory influence on the functional expression of D1-mediated responses in dopamine-denervated rats, and propose new possible therapeutic approaches in the treatment of Parkinson's disease.

TL;DR: It is suggested that 5-HT3 receptor activation plays a permissive role in alcohol preference and inhibited ethanol consumption during the 6 days of treatment by 25%, 50% and 75%, respectively, without modifying total fluid intake.
Abstract: The effect of the selective 5-HT3 receptor antagonist MDL 72222 on voluntary ethanol consumption was examined in Sardinian ethanol-preferring (SP) rats in a free choice (10% ethanol and water) experiment. SP rats consumed 8.1 ± 1.1 g/kg ethanol daily. MDL 72222 treatment (3.0, 5.0 and 7.0 mg/kg i.p. 3 times daily for 6 days) inhibited ethanol consumption during the 6 days of treatment by 25%, 50% and 75%, respectively, without modifying total fluid intake. We suggest that 5-HT3 receptor activation plays a permissive role in alcohol preference.
