SIVIM Deciduous Forests - Database of deciduous forests from the Iberian Peninsula

'SIVIM Deciduous Forests' is a thematic database established in 2015, focused on forest vegetation from the Iberian Peninsula and southern France. It was registered in the Global Index of Vegetation Databases (GIVD ID: EU-00-023) in January 2016. All types of temperate and submediterranean non-riparian deciduous forests of the phytosociological classes Carpino-Fagetea sylvaticae, Quercetea pubescentis and Quercetea robori-petraeae (formerly combined in the class Querco-Fagetea) are represented in the database. Currently, it contains 6,642 published vegetation plots of beech, birch, ash, lime and other deciduous mixed forests, as well as forests dominated by different species of deciduous and marcescent oaks, 100% of them classified at association level. Data are stored in TURBOVEG format, and are available upon request from the international vegetation-plot databases EVA and sPlot in semi-restricted regime. The relevés have also been included in SIVIM database, and thus they are freely available online. However, in SIVIM Deciduous Forests geolocation accuracy has been improved and the taxonomy and syntaxonomy unified. Plot size is available for 73% of the relevés, of which 82% are between 100 and 400 m2. Plant taxonomy is standardized to Flora iberica. During the last four years, data of SIVIM Deciduous Forests were requested via EVA and sPlot for different projects, and have been used for several studies with various objectives, from floristic, vegetation and habitat-related topics to macroecological studies, and from local to global scales

Maxillary dentigerous cyst and supernumerary tooth. Is it a frequent association?

Dentigerous cysts, also known as follicular cysts, are a relatively common pathology in our field. They are associated with unerupted or semi-erupted teeth and are usually not related to supernumerary teeth. OBJECTIVE: To describe a dentigerous cyst case associated to a supernumerary tooth. CASE-REPORT: A large-sized dentigerous cyst is described, associated with a supernumerary tooth, affecting the whole maxillary anterior area. Appropriate treatment consists of performing root canals and a Partsch II procedure with a cystectomy, extracting the unerupted teeth, carrying out an apicoectomy and retro-filling the affected teeth. The defect is filled with a bone xenograft. Possible therapeutic alternatives and the connection between the dentigerous cysts and supernumerary teeth are considered in the discussion

Kinetico-mechanistic study on the C-H bond activation of primary benzylamines; cooperative and solid-state cyclopalladation on dimeric complexesss

The cyclometallation reactions of dinuclear μ-acetato complexes of the type [Pd(AcO)(μ-AcO)L]2 (L = 4-RC6H4CH2NH2, R = H, Cl, F, CF3), a process found to occur readily even in the solid state, have been studied from a kinetico-mechanistic perspective. Data indicate that the dinuclear acetato bridged derivatives are excellent starting materials to activate carbon-hydrogen bonds in a facile way. In all cases the established concerted ambiphilic proton abstraction by a coordinated acetato ligand has been proved. The metallation has also been found to occur in a cooperative manner, with the metallation of the first palladium unit of the dimeric complex being rate determining; no intermediate mono-metallated compounds are observed in any of the processes. The kinetically favoured bis-cyclopalladated compound obtained after complete C-H bond activation does not correspond to the final isolated XRD-characterized complexes. This species, bearing the classical open-book dimeric form, has a much more complex structure than the final isolated compound, with different types of acetato ligand

Masters of Wine on Twitter: presence, activity, impact and community structure

[EN] Globalisation, the Internet and social media have changed the kind of actors with influence in the wine industry and the way these actors create signals to communicate credible information about experience and trust attributes. Among the most prestigious experts in the world of wine are the Masters of Wine (MW). Although initially devoted to international trade, they have spread their activities and their opinion is more and more appreciated by producers and consumers. The main objective of this article is to determine this community of experts¿ behaviour on Twitter. In order to do so, four factors (presence, activity, impact and community) have been considered. All Twitter profiles belonging to users awarded with the MW qualification were identified and analysed. In addition, a set of 35,653 tweets published by the MWs were retrieved and analysed through descriptive statistics. The results show MWs on Twitter as high attractors (number of followers), moderate publishers (original contents published), moderate influencers (number of likes and retweets), and low interactors (number of friends and mentions to other users). These findings reveal that the MW community is not using Twitter to gain or reinforce their reputation as an accredited expert in the wine industry, giving more influential space on Twitter to consumers and amateurs.This work has been supported by the eMarketwine project (CS02016-78775-R), funded by the Ministry of Economy and Competitiveness (MINECO) in Spain. The authors sincerely appreciate the work carried out by the two anonymous reviewers, who have helped to improve the manuscript in a remarkable way.Orduña Malea, E.; Font-Julian, CI.; Ontalba Ruipérez, JA.; Compes López, R.

Pyogenic granuloma/Peripheral giant-cell granuloma associated with implants

Introduction: pyogenic granuloma (PG) and peripheral giant-cell granuloma (PGCG) are two of the most common inflammatory lesions associated with implants; however, there is no established pathway for treatment of these conditions. This paper aims to illustrate the successful treatment of PG and PGCG and also report a systematic review of the literature regarding the various treatments proposed. Methods: to collect relevant information about previous treatments for PG and PGCG involving implants we carried out electronic searches of publications with the key words 'granuloma', 'oral', and 'implants' from the last 15 years on the databases Pubmed, National Library of Medicine's Medline, Scielo, Scopus, and Cochrane Library. Results: from the electronic search 16 case reports were found showing excision and curettage as the main successful treatment. As no clinical trials or observational studies were identified the authors agreed to present results from a review perspective. Conclusion: this is the largest analysis of PG and PGCG associated with implants published to date. Our review would suggest that PGCG associated with implants appears to have a more aggressive nature; however the level of evidence is very limited. Further cohort studies with representative sample sizes and standard outcome measures are necessary for better understanding of these conditions

Magnetic behavior of heterometallic wheels having a [MnIV6M2O9]10+ core with M = Ca2+ and Sr2+

Two new heterometallic MnIV−M2+ compounds with formula [Mn6M2O9(4-tBuC6H4COO)10(4-tBuC6H4COOH)5] (M = Ca2+ (1), Sr2+ (2)) have been crystallized. The core of both compounds consists of a planar Mn6 ring, where the MnIV ions are alternatively bridged by (μ3-O)2(μ-RCOO) and (μ4-O)(μ-RCOO)2 ligands, and the two alkaline earth ions are located to both sides of the wheel, linked to the oxo bridges, generating three fused [Mn2M2O4]4+ cuboids. These compounds show a net antiferromagnetic behavior, more important for 2 (Sr2+) than for 1 (Ca2+). The fitting of the experimental data was performed with the support of DFT calculations, considering four different exchange pathways: two between adjacent MnIV ions (J1 and J2) and two between nonadjacent MnIV ions (J3 and J4). The results of the analysis show that J1 and J2 are of the opposite sign, the ferromagnetic contribution corresponding to the [Mn2(μ4- O)(μ-RCOO)2]4+ unit (J2). The influence of the M2+ ions in the magnetic behavior is analyzed for 1 and 2 and for three hypothetical models with the structural parameters of 1 containing Mg2+, Sr2+ or without the M2+ ions. In spite of the diamagnetic character of the alkaline earth ions, their influence on the magnetic behavior has been evidenced and correlated with their polarizing effect. Moreover, the magnetic interactions between nonadjacent ions are non-negligible

Polymorphism of Cocrystals: The Promiscuous Behavior of Agomelatine

It has been traditionally suggested that polymorphism of cocrystals is a phenomenon seen less frequently than in monocomponent crystals. However, since the research on cocrystals has recently experienced a big growth, the number of solved structures of polymorphic cocrystals in the Cambridge Structural Database has increased, which can help to understand better whether a lower impact of this phenomenon exists or not in multicomponent crystals. In this paper we describe the cocrystal landscape of agomelatine, a particularly promiscuous drug able to cocrystallize with up to nine different coformers. Interestingly, two of those coformers have produced polymorphic cocrystals during the screening, which converts agomelatine into a new example that questions the traditional belief of the lesser impact of polymorphism in cocrystals and highlights the importance of polymorphism studies in cocrystal screening. Our work is completed with the determination of the crystal structures of the new forms from combined single crystal/laboratory X-ray powder diffraction data

Expanding the Crystal Form Landscape of the Antiviral Drug Adefovir Dipivoxil

The solid state of adefovir dipivoxil (AD) has been revisited. In the present article we extend the knowledge about the solid state of this pharmaceutical prodrug. The stability landscape of the amorphous form with respect to the anhydrous and hydrate crystalline forms has been studied, and the use of an antiplasticizing agent to increase its Tg is described. The crystal structure of the elusive anhydrous form I has been determined from laboratory powder X-ray diffraction data by means of direct space methods using the computing program FOX. In addition, three new isostructural solvates of AD (methanol, ethylenglycol, and methylethylketone) have been discovered and structurally characterized by single cristal X-ray diffraction

Heterodi- (Fe, Pd/Pt) and heterotrimetallic (Fe2, Pd) complexes derived from 4-(ferrocenylmethyl)-N-(2-methoxyethyl)-3,5-diphenylpyrazole as potential antitumoral agents

The study of the reactivity of the pyrazole derivative 1-[MeO-(CH2)2]-3,5-Ph2-4-(CH2Fc) (C3N2) (1, Fc = ferrocenyl) with Na2[PdCl4], Pd(OAc)2, and [MCl2(dmso)2] (M = Pd or Pt,dmso = dimethyl sulfoxide) has allowed us to isolate trans-[Pd{κ-N-(1-{MeO(CH2)2}-3,5-Ph2-4-{CH2Fc} {C3N2})}2Cl2] (2), [Pd{κ2-C,N(1-{MeO(CH2)2}-3-{C6H4}-5-Ph-{C3N2})}{κ-N-(1-{MeO(CH2)2}-3,5-Ph2-4-{CH2Fc} {C3N2})}Cl] (3), [Pd{κ2-C,N(1-{MeO(CH2)2}-3-{C6H4}-4-{CH2Fc}-5-Ph-{C3N2})}Cl-(PPh3)] (4), and the trans (5) and cis (6) isomers of [Pt{κ-N-(1-{MeO(CH2)2}-3,5-Ph24-{CH2Fc} {C3N2})}Cl2(dmso)]. Compound 1 acts as a N (in 2, 5, and 6) or (C,N) donor ligand (in 4) and shows both binding modes in 3. The cytotoxic assessment of 1 6 against MCF7, MDA-MB231 (breast), and HCT-116 (colon) cancer cell lines reveal that (1) 1 is more potent than 1-[MeO(CH2)2]-3,5-Ph2-(C3HN2) (V), (2) 2 6 have cytotoxic activity, (3) 2 and 3 are less active than 4 6, and (4) 6 is the most potent compound against the three cancer cell lines
