    ITALIANO: Famosa per la rivolta del Tuchinaggio di fine Trecento, l’area del Canavese, nel Piemonte nord-occidentale, fornisce numerose informazioni relative al rapporto fra signori e sudditi su un arco cronologico molto più ampio. A partire dall’analisi di un ricco corpus di fonti (visite pastorali, cronache, fonti giudiziarie, notarili e statutarie), il saggio prende in esame la dialettica fra domini e homines nella prima metà del secolo XIV, individuando gradi differenti di consolidamento istituzionale comunitario nelle diverse vallate alpine del Canavese e collocando le vicende locali in un percorso di crescita delle comunità attestato in larga parte dell’arco alpino. / ENGLISH: Famous for the late 14th-century revolt known as Tuchinaggio, the Canavese area, in north-western Piedmont, provides significant information concerning the relationship between lords and subjects in a longer time span. By analysing a wide range of sources (pastoral visitations, chronicles, court and notarial records, statutes), the essay examines the domini-homines dialectic in the first half of the 14th century: in the Canavese Alpine valleys various degrees of institutional consolidation of communities can be outlined, identifying a process of growth common to communities in the entire Alpine Arc

    ITALIANO: Durante il Congresso che si tenne a Cividale in occasione dell’XI centenario della morte di Paolo Diacono, fu promossa la costituzione di una commissione che curasse la nuova edizione della sua opera omnia. Forti riserve su questa iniziativa espresse l’Istituto storico italiano perché riteneva fosse sua prerogativa la stampa delle principali opere di Paolo: la Historia Romana e la Historia Langobardorum. Di diverso parere era Carlo Cipolla, secondo cui l’edizione della Historia Langobardorum spettava alla Deputazione veneta di storia patria. La disputa si concluse con una sorta di compromesso: Amedeo Crivellucci avrebbe curato per conto dell’Istituto storico la stampa delle Historiae, ma si sarebbe associato nell’impresa Cipolla. Il saggio ricostruisce la vicenda che portò alla collaborazione tra i due eminenti studiosi, la segue sino alla brusca interruzione che risale al 1904, per poi soffermarsi sulle ricerche condotte dal solo Crivellucci sino al 1914. Sulla base della documentazione archivistica viene così ricostruita una pagina di storia della medievistica di primo Novecento di cui non rimangono quasi tracce nelle opere a stampa, ma che ha visto coinvolti alcuni dei principali studiosi attivi in quel periodo (Cipolla e Crivellucci, ma anche Villari e Schiaparelli). / ENGLISH: During the congress on Paolo Diacono held in Cividale del Friuli in 1899 (eleven centuries after Paolo’s death) a scientific committee decided to publish a new edition of Paolo’s opera omnia. A sort of scholar jealousy arised: the Istituto storico italiano thought that its own duty was to publish the Historia romana and the Historia Langobardorum, the main works written by Paolo. The eminent scholar Carlo Cipolla, on the contrary, believed that task was of the Deputazione veneta di storia patria. A compromise was signed: Amedeo Crivellucci (of the Istituto storico) invited Cipolla to collaborate on the edition of both Histories. The present essay recalls that collaboration (that unfortunately was interrupted in 1904) studying the correspondence between Cipolla, Crivellucci and other historians (Villari, Crivellucci) and reopening an unknown page of the history of Italian medievistic scholarship

    No full text
    Background. In chronic kidney disease, the activation of the renin-angiotensin–aldosterone system (RAAS) and renal inflammation stimulates renal fibrosis and the progression to endstage renal disease. The low levels of vitamin D receptor (VDR) and its activators (VDRAs) contribute to worsen secondary hyperparathyroidismand renal fibrosis. Methods. The 7/8 nephrectomy model of experimental chronic renal failure (CRF) was used to examine the anti-fibrotic effects of treatment with two VDRAs, paricalcitol and calcitriol, at equivalent doses (3/1 dose ratio) during 4 weeks. Results. CRF increased the activation of the RAAS, renal inflammation and interstitial fibrosis. Paricalcitol treatment reduced renal collagen I and renal interstitial fibrosis by decreasing the activation of the RAAS through renal changes in renin, angiotensin receptor 1 (ATR1) and ATR2 mRNAs levels and renal inflammation by decreasing renal inflammatory leucocytes (CD45), a desintegrin and metalloproteinase mRNA, transforming growth factor beta mRNA and protein, and maintaining E-cadherin mRNA levels. Calcitriol showed similar trends without significant changes in most of these biomarkers. Conclusions. Paricalcitol effectively attenuated the renal interstitial fibrosis induced by CRF through a combination of inhibitory actions on the RAAS, inflammation and epithelial/mesenchymal transition.This study was supported by Instituto de Salud Carlos III (ISCIII)—Fondo de Investigación Sanitaria (FIS07/0893, FIS10/00896; FIS13/00014, FIS16/00637, FIS17/00715 and FIS19/00532), Fondo Europeo de Desarrollo Regional (FEDER), Plan de Ciencia, Tecnología e Innovación 2013- 2017 y 2018-2022 del Principado de Asturias (GRUPIN14-028, IDI-2018-000152), Fundación Renal Ínigo Álvarez de Toledo (FRIAT) and Retic REDinREN from ISCIII (RD06/0016/1013, RD12/0021/0023, RD16/0009/0017, RD12/0021/0006 and RD16/0009/0018) and Abbott Pharmaceuticals (ACA-SPAI-08-22/2008).

    The effect of pasteurization in the expression of bovine milk microRNA

    No full text
    The edaphoclimatic conditions in Asturias (northwest Spain) enable the presence of milk production systems oscillating between farms based on grazing and low consumption of conserved feed and forages as well as a low density of animals per surface, and intensive farms with confined animals, with a higher density, and higher consumption of conserved feed and forages. Identifying milk according to its origin is a useful way to highlight the positive effects of grazing farms on the environment, milk quality, animal welfare, and social aspects. MicroRNAs (miRNAs) are 21-25-nucleotide small RNAs that perform various functions within cells, including gene expression regulation. They can be profiled through microarray, quantitative real-time Polymerase Chain Reaction (RT-qPCR), or sequencing. Their expressions vary according to the genetic context and external factors to the animal (feeding, handling, etc.). Besides, these molecules are resistant to adverse physicochemical conditions, which make them potential biomarkers. In previous studies, a set of miRNAs from raw milk with differential expression according to some ingredients of the diet were determined. However, it is important to evaluate the effect of technological treatments, in milk factories,(pasteurization, fermentation, sterilization, etc.) on these miRNAs. Furthermore, taking into account the potential bioactivity of milk according to its miRNAs content, it is important to assess miRNAs milk content intended for human consumption. In the present study, we analysed the effect of pasteurization on the miRNAs determined as biomarkers. For that purpose, the expression of nine miRNAs was analysed in the same volume of twenty tank milk samples before and after pasteurization. The expression analysis of the different biomarkers in pasteurized and non-pasteurized milk showed that the expression of most miRNAs was lower after pasteurization, although without significant differences (P<0.05). Moreover, pasteurization of raw milk affects differently fat and cell fraction. These results suggest that miRNAs are quite resistant to pasteurization.- L.

    BACKGROUND: In Chronic Kidney Disease serum phosphorus elevations stimulate PTH production causing severe alterations in bone-vasculature axis. PTH is the main regulator of Receptor activator of NFKB (RANK)/RANK ligand (RANKL)/osteoprotegerin (OPG) system, essential for bone maintenance, which also plays an important role in vascular smooth muscle cells (VSMCs) calcification. The discovery of a new RANKL receptor, leucine-rich repeat-containing G-protein-coupled receptor 4 (LGR4), important for osteoblast differentiation but with unknown role in VC, led us to examine LGR4 contribution in high P/high PTH-driven vascular calcification (VC). METHODS: In vivo studies were conducted in subtotally nephrectomized rats fed normal or high phosphorus diet, with and without parathyroidectomy. Parathyroidectomized rat were supplemented with PTH 1-34 to achieve physiological serum PTH levels). In vitro studies were performed in rat aortic VSMCs cultured in control medium, calcifying medium (CM) or CM plus 10-7 vs 10-9M PTH. RESULTS: Rats fed high phosphorus, significantly increased aortic calcium content. Similarly, calcium deposition was higher in VSMCs exposed to CM. Both conditions were associated with increased RANKL and LGR4 and decreased OPG aorta expression, and exacerbated by high PTH. Silencing of LGR4 or PTH1R attenuated the high PTH-driven increases in calcium deposition. Furthermore, PTH1R silencing and pharmacological inhibition of protein kinase (PK) A, but not of PKC, prevented the increases in RANKL and LGR4 and decreased OPG. Treatment with PKA agonist corroborated that LGR4 regulation is a PTH/PKA-driven process. CONCLUSIONS: High PTH increases LGR4 and RANKL and decreases OPG expression in aorta, thereby favoring vascular calcification. The hormone's direct pro-calcifying actions involve PTH1R binding and PKA activation.The study was supported by Instituto de Salud Carlos III (ISCIII) - Fondo de Investigación Sanitaria (FIS 17/00715, FIS16/ 00637 and FIS 10/00896), Fondo Europeo de Desarrollo Regional (FEDER), Plan de Ciencia, Tecnología e Innovación 2013-2017 y 2018-2022 del Principado de Asturias (GRUPIN14-028, IDI-2018-000152), Fundación Renal Íñigo Álvarez de Toledo (FRIAT) and ISCIII Retic REDinREN (RD06/0016/1013, RD12/0021/1023 and RD16/0009/0017 and RD16/0009/0007).

    Markovnikov Wacker-Tsuji Oxidation of Allyl(hetero)arenes and Application in a One-Pot Photo-Metal-Biocatalytic Approach to Enantioenriched Amines and Alcohols

    No full text
    The Wacker-Tsuji aerobic oxidation of various allyl(hetero)arenes under photocatalytic conditions to form the corresponding methyl ketones is presented. By using a palladium complex [PdCl2(MeCN)2] and the photosensitizer [Acr-Mes]ClO4 in aqueous medium and at room temperature, and by simple irradiation with blue led light, the desired carbonyl compounds were synthesized with high conversions (>80%) and excellent selectivities (>90%). The key process was the transient formation of Pd nanoparticles that can activate oxygen, thus recycling the Pd(II) species necessary in the Wacker oxidative reaction. While light irradiation was strictly mandatory, the addition of the photocatalyst improved the reaction selectivity, due to the formation of the starting allyl(hetero)arene from some of the obtained byproducts, thus entering back in the Wacker-Tsuji catalytic cycle. Once optimized, the oxidation reaction was combined in a one-pot two-step sequential protocol with an enzymatic transformation. Depending on the biocatalyst employed, i.e. an amine transaminase or an alcohol dehydrogenase, the corresponding (R)- and (S)-1-arylpropan-2-amines or 1-arylpropan-2-ols, respectively, could be synthesized in most cases with high yields (>70%) and in enantiopure form. Finally, an application of this photo-metal-biocatalytic strategy has been demonstrated in order to get access in a straightforward manner to selegiline, an anti-Parkinson drug
