Analysis of bacterial communities of infected primary teeth in a Mexican population
2020
Background The objective of this study was to describe the bacterial communities associated with pediatric patients with endodontic infections of temporal teeth by targeting the 16S rRNA gene using pyrosequencing. Material and Methods Microbiological samples were obtained from the lower primary molars of thirteen 13 pediatric patients with dental infections. An aspiration method for microbiological sampling was used. The identification of microbiota employing the pyrosequencing method by targeting the 16S gene was performed. Results Ribosomal 16S RNA gene sequences were amplified, obtaining a total of 16,182 sequences from 13 primary infected molars (13 different individuals) by pyrosequenc…
The coffee-machine bacteriome: biodiversity and colonisation of the wasted coffee tray leach
2015
AbstractMicrobial communities are ubiquitous in both natural and artificial environments. However, microbial diversity is usually reduced under strong selection pressures, such as those present in habitats rich in recalcitrant or toxic compounds displaying antimicrobial properties. Caffeine is a natural alkaloid present in coffee, tea and soft drinks with well-known antibacterial properties. Here we present the first systematic analysis of coffee machine-associated bacteria. We sampled the coffee waste reservoir of ten different Nespresso machines and conducted a dynamic monitoring of the colonization process in a new machine. Our results reveal the existence of a varied bacterial community…
A uniform quantificational logic for algebraic notions ofcontext
2002
A quantificational framework of formal reasoning is proposed, which emphasises the pattern of entering and exiting context. Contexts are modelled by an algebraic structure which reflects the order and manner in which context is entered into and exited from. The equations of the algebra partitions context terms into equivalence classes. A formal semantics is defined, containing models that map equivalence classes of certain context terms to sets of first order structures. The corresponding Hilbert system incorporates the algebraic equations as axioms asserted in context. In this way a uniform logic for arbitrary algebras of context is obtained. Soundness and completeness are proved. In semig…

Insects’ potential: Understanding the functional role of their gut microbiome
2021
The study of insect-associated microbial communities is a field of great importance in agriculture, principally because of the role insects play as pests. In addition, there is a recent focus on the potential of the insect gut microbiome in areas such as biotechnology, given some microorganisms produce molecules with biotechnological and industrial applications, and also in biomedicine, since some bacteria and fungi are a reservoir of antibiotic resistance genes (ARGs). To date, most studies aiming to characterize the role of the gut microbiome of insects have been based on high-throughput sequencing of the 16S rRNA gene and/or metagenomics. However, recently functional approaches such as m…
IL VICERÉ GARÇIA DE TOLEDO E I CANTIERI REALI. UN LOGGIATO “ALLA GENOVESE” PER PALERMO
2014
The State Archive of Genoa keeps one of the few drawings related to the reconfiguration projects of the Royal Palace of Palermo in modern age. It's a pen drawing, partly in watercolor, depicting partially the front and the pavement of a long open gallery to be realized in the new eastern façade of the palace; the plan is attached to the contract, signed March 14th 1567 in Genoa, where the sculptors Giacomo Guidetti and Antonio Carabio were commissioned to supply all the necessary marbles and floor surfaces to realize the loggia.
IL SERVIZIO DI DISTRIBUZIONE DEL GAS TRA REGOLAZIONE STATALE E REGIONALE DOPO LA SENTENZA DELLA CORTE COSTITUZIONALE N.16 DEL 2020
2021
Lo studio tratta la complessa evoluzione normativa del mercato del gas naturale che ha imposto, dopo vari rinvii, alle amministrazioni comunali l’obbligo di assumere, in tempi brevi, decisioni e provvedimenti con forte impatto sulla futura organizzazione del servizio di distribuzione del gas e sugli interessi degli utenti. In particolare si approfondisce la disciplina statale, quella regionale siciliana, con riguardo alla sentenza della Corte Costituzionale n. 16 del 2020 con la quale si è ritenuto che sebbene alla Regione Siciliana sia attribuita, ai sensi dello Statuto di autonomia, la competenza legislativa concorrente in materia di servizi pubblici di prevalente interesse regionale, tal…
Novel Probiotic Bifidobacterium bifidum CECT 7366 Strain Active against the Pathogenic Bacterium Helicobacter pylori▿
2010
ABSTRACT Helicobacter pylori is considered one of the major risk factors underlying the development of gastritis and gastric and duodenal ulcers. Moreover, 50% of the population carries this bacterium, and consequently, when it is detected, eradication of H. pylori is strongly recommended. Regarding the use of probiotics as functional agents, several studies have shown that there is a direct relationship between the addition of certain probiotic bacteria and in vitro inhibition of H. pylori ; however, in vivo studies showing bifidobacterial activity against H. pylori remain scarce. In this study, a Bifidobacterium bifidum strain which proved active in vitro against H. pylori has been isolat…
A study on Pomatoschistus tortonesei Miller 1968 (Perciformes, Gobiidae) reveals the Siculo-Tunisian Strait (STS) as a breakpoint to gene flow in the…
2009
The current genetic structure of P. tortonesei, exclusively inhabiting lagoons, may reflect a Plio-Pleistocene colonisation of an ancestor line which has undergone phases of population decline and expansion, following alternate cooling phases. Regarding the calculation of divergence time, it has been estimated that P. tortonesei seems to be the most recent species within the Pomatoschistus genus. It appears also that the discrepancy of P. tortonesei into two distinct phyletic lineages occurred 0.1 Mya. Recurring shifts in sea level and sea surface temperatures of Mediterranean Sea caused the desiccation of shallower lagoons and the consequent bottleneck phenomena of the brackish populations…
Fundamental isomorphism theorems for quantum groups
2017
The lattice of subgroups of a group is the subject of numerous results revolving around the central theme of decomposing the group into "chunks" (subquotients) that can then be compared to one another in various ways. Examples of results in this class would be the Noether isomorphism theorems, Zassenhaus' butterfly lemma, the Schreier refinement theorem for subnormal series of subgroups, the Dedekind modularity law, and last but not least the Jordan-H\"older theorem. We discuss analogues of the above-mentioned results in the context of locally compact quantum groups and linearly reductive quantum groups. The nature of the two cases is different: the former is operator algebraic and the latt…
