Reproducing subgroups of Sp(2,R)Sp(2,\mathbb{R}). Part I: algebraic classification

We classify the connected Lie subgroups of the symplectic group $Sp(2,\mathbb{R})$ whose elements are matrices in block lower triangular form. The classification is up to conjugation within $Sp(2,\mathbb{R})$. Their study is motivated by the need of a unified approach to continuous 2D signal analyses, as those provided by wavelets and shearlets.Comment: 26 page

Effect of dietary supplementation with ultramicronized palmitoylethanolamide in maintaining remission in cats with nonflea hypersensitivity dermatitis: a double-blind, multicentre, randomized, placebo-controlled study

Background Feline nonflea hypersensitivity dermatitis (NFHD) is a frequent cause of over-grooming, scratching and skin lesions. Multimodal therapy often is necessary. Hypothesis/Objectives To investigate the efficacy of ultramicronized palmitoylethanolamide (PEA-um) in maintaining methylprednisolone-induced remission in NFHD cats. Animals Fifty-seven NFHD cats with nonseasonal pruritus were enrolled originally, of which 25 completed all study requirements to be eligible for analysis. Methods and materials Cats were randomly assigned to PEA-um (15 mg/kg per os, once daily; n = 29) or placebo (n = 28) while receiving a 28 day tapering methylprednisolone course. Cats responding favourably to methylprednisolone were then administered only PEA-um (n = 21) or placebo (n = 23) for another eight weeks, followed by a four week long treatment-free period. Cats were maintained in the study until relapse or study end, whichever came first. Primary outcome was time to relapse. Secondary outcomes were pruritus Visual Analog Scale (pVAS), SCORing Feline Allergic Dermatitis scale (SCORFAD) and owner Global Assessment Score (GAS). Results Mean relapse time was 40.5 days (+/- 7.8 SE) in PEA-um treated cats (n = 13) and 22.2 days (+/- 3.7 SE) for placebo (n = 12; P = 0.04). On Day 28, the severity of pruritus was lower in the PEA-um treated cats compared to placebo (P = 0.03). Mean worsening of pruritus at the final study day was lower in the PEA-um group compared to placebo (P = 0.04), whereas SCORFAD was not different between groups. Mean owner GAS at the final study day was better in the PEA-um than the placebo-treated group (P = 0.05). Conclusion and clinical importance Ultramicronized palmitoylethanolamide could represent an effective and safe option to delay relapse in NFHD cats

Società europea, regimi normativi e tutele "occupazionali"

In mancanza di indicazioni specifiche del legislatore comunitario risulta problematica l'individuazione del regime normativo giuslavoristico e previdenziale delle relazioni individuali di lavoro nell'ambito di una Società europea. A fronte del criterio di massima della prevalenza, in caso di diversa previsione, della legislazione dello Stato membro della sede sociale della Società europea, rilevano infatti il principio della cd. «territorialità» della normativa giuslavoristica, e la sua inderogabilità, nonché i connessi profili di ordine previdenziale. Snodo esemplare della questione è rappresentato dalle fattispecie implicanti una contrazione degli standard occupazionali: ove, ferma l'esigenza di individuazione della normativa nazionale «giuslavoristica» cui riportare concretamente l'esplicazione del potere datoriale in relazione ai dipendenti della Società europea dislocati in diverse realtà nazionali, si tratta altresì di stabilire i corrispondenti trattamenti previdenziali di tutela «occupazionale» fruibili dai medesimi lavoratori, in termini che rendono prospettabile l'operare di più regimi normativi nazionali concorrent
