PublicationOpen AccessArteterapia en Europa. Breve recorrido desde sus orígenes. Fundamentos y corrientes.(Ediciones Complutense, 0027-05-27) López Martínez, María Dolores; Expresión Plástica, Musical y Dinámica; Facultades de la UMUEl presente capítulo ofrece una visión panorámica del desarrollo histórico, disciplinar y profesional de la arteterapia en Europa, desde sus orígenes hasta su consolidación actual. Se identifican los principales hitos que han marcado su evolución, desde las primeras manifestaciones del valor terapéutico del arte hasta la configuración contemporánea de la disciplina. El artículo se estructura en cuatro apartados que abordan: los antecedentes del uso del arte con fines terapéuticos, la institucionalización de la arteterapia como práctica diferenciada, su expansión y consolidación en el ámbito europeo y los desafíos actuales en los campos profesional, formativo y de investigación. Las conclusiones destacan el notable crecimiento de la arteterapia en las últimas décadas, tanto en su reconocimiento académico y científico como en su aplicación en contextos sociales, educativos y clínico-sanitarios. Se subraya su carácter multidisciplinar, su valor integrador y el impacto positivo evidenciado en numerosos estudios. No obstante, se señala la necesidad de fortalecer la coordinación entre entidades europeas, fomentar la inserción laboral de los profesionales, avanzar en la acreditación y homologación de programas formativos y asegurar un mayor respaldo institucional y financiero. En síntesis, la arteterapia en Europa constituye hoy un campo en expansión, con una presencia creciente en la educación superior, la práctica profesional y la investigación científica, contribuyendo de manera significativa al bienestar físico, emocional y social.Palabras clave: Arteterapia, terapias creativas, historia, Europa, regulación profesional.- PublicationOpen AccessEffect of different enamel preconditioning protocols on the adhesion of ceramic brackets(0028-05-26) Lara Cendán; Luis-Alberto Bravo-González; Bravo González, Luis Alberto; Ortiz Ruiz, Antonio José; Martínez Beneyto, Yolanda; Vicente Hernández, Ascensión; Dermatología, Estomatología, Radiología y Medicina Física; Facultades de la UMU::Facultad de MedicinaThis study aimed to compare the adhesion of Clarity Advanced ceramic brackets bonded with APC Flash Free (APC FF) and Transbond XT (TXT) using different enamel conditioning protocols. Brackets were bonded to extracted bovine incisors, which were divided into 6 groups: 1)Transbond Plus Self Etching Primer (TSEP)/APC FF, 2)Etching/TSEP/APC FF, 3)Polishing/TSEP/APC FF, 4) TSEP/TXT, 5)Etching/TSEP/TXT and 6)Polishing/TSEP/TXT. Shear bond strength was measured using a universal testing machine. After debonding, each tooth was assigned an Adhesive Remnant Index (ARI) score. The enamel was observed using a scanning electron microscope (SEM). The penetrability of TSEP and composites was determined using confocal microscopy. The bond strength of Etching/TSEP/TXT and Polishing/TSEP/TXT groups was significantly higher than that of the remaining groups, with Etching/TSEP/TXT being significantly higher than Polishing/TSEP/TXT (p<0.05). With APC FF, there was a tendency for an increase in residual adhesive when etching and with TXT when polishing. SEM showed that etching produced the most porous enamel surface. For both APC FF and TXT bonded brackets, TSEP penetration was similar and significantly higher after etching (p=0.000). APC FF and TXT had similar and significantly higher penetration in the etched groups (p=0.000). Ceramic brackets bonded with TXT pre-etching the enamel before applying TSEP showed the most favourable adhesive characteristics.
- PublicationOpen AccessSynthesis, Luminescence, and Electrochemistry of Tris-Chelate Platinum(IV) Complexes with Cyclometalated N-Heterocyclic Carbene Ligands and Aromatic Diimines(ACS Publications, 2024-12-19) Serrano Guarinos, José; Jiménez García, Adrián; Bautista, Delia; González Herrero, Pablo; Vivancos Ureña, Ángela; Química Inorgánica; Facultades de la UMU::Facultad de QuímicaDicationic, C2-symmetrical, tris-chelate Pt(IV) com plexes of general formula [Pt(trz)2(N∧N)](OTf)2, bearing two cyclometalated 4-butyl-3-methyl-1-phenyl-1H-1,2,3-triazol-5-yli- dene (trz) ligands and one aromatic diimine [N∧N = 2,2′- bipyridine (bpy, 2), 4,4′-di-tert-butyl-2,2′-bipyridine (dbbpy, 3), 4,4′-dimethoxi-2,2′-bipyridine (dMeO-bpy, 4), 1,10-phenanthro- line (phen, 5), 4,7-diphenyl-1,10-phenanthroline (bphen, 6), dipyrido[3,2-a:2′,3′-c]phenazine (dppz, 7), or 2,3- diphenylpyrazino[2,3-f ][1,10]phenanthroline (dpprzphen, 8)] are obtained through chloride abstraction from [PtCl2(trz)2] (1) using AgOTf in the presence of the corresponding diimine. Complexes 2−4 show long-lived phosphorescence from 3LC excited states involving the diimine ligand, with quantum yields that reach 0.18 in solution and 0.58 in the solid matrix at room temperature for 3. Derivatives with more extended aromatic systems show dual phosphorescent/fluorescent emissions (5, 6) or mainly fluorescence (7, 8) in solution. Comparisons with similar complexes bearing cyclometalated 2-arylpyridines instead of aryl-N-heterocyclic carbenes indicate that the {Pt(trz)2} subunit is crucial to enable efficient emissions from diimine-centered excited states. It is also shown that the introduction of protective bulky substituents on the diimine, such as the tert-butyl groups in 3, is a key strategy to reach higher emission efficiencies. The new compounds represent rare examples of luminescent Pt(IV) complexes that show quasi-reversible one-electron reductions, indicating an unusually high redox stability.

- PublicationOpen AccessPhotoinduced Reductive C−O Couplings from Unsymmetrical Bis-Cyclometalated Pt(IV) Dicarboxylato Complexes(American Chemical Society, 2024-12-27) López López, Juan Carlos; Bautista, Delia; González Herrero, Pablo; Química Inorgánica; Facultades de la UMU::Facultad de QuímicaUnsymmetrical bis-cyclometalated dicarboxylato complexes (OC-6-32)-[Pt(tpy)2(O2CR)2] [tpy = cyclometalated 2-(ptolyl) pyridine, R = t-Bu (1), Me (2), Ph (3), CF3 (4)], are obtained from the reaction of cis-[Pt(tpy)2] with the appropriate PhI(O2CR)2 reagent. Treatment of complexes of this type with different carboxylates (R’CO2 −) results in the formation of mixed-carboxylato derivatives, namely (OC-6-43)-[Pt(tpy)2(O2CMe)(O2CR′)] [R′ = t- Bu (5), CF3 (6), Ph (7)], (OC-6-34)-[Pt(tpy)2(O2CCF3)(O2CR′)] [R′ = t-Bu (8), Me (9), Ph (10)], and (OC-6-34)-[Pt(tpy)2(O2C-t- Bu)(O2CMe)] (11). Irradiation of 1−3 and 5−11 with UV light (365 nm) in MeCN gives 5-methyl-2-(2-pyridyl)phenyl pivalate (12), 5-methyl-2-(2-pyridyl)phenyl acetate (13) or 5-methyl-2-(2- pyridyl)phenyl benzoate (14) as the major photoproduct from most complexes, resulting from a reductive C−O coupling between a tpy ligand and a carboxylato ligand. Cyclometalation of 12−14 at the ensuing Pt(II) species to produce cis-[Pt(tpy)(tpyO2CR/R′)], reduction to cis-[Pt(tpy)2] and isomerization to (OC-6-33)- [Pt(tpy)2(O2CR/R′)2] are identified as secondary processes in most cases. In contrast, complex 4 exclusively photoisomerizes to (OC-6-33)-[Pt(tpy)2(O2CCF3)2] (4′). The C−O couplings are favored for the most electron-rich carboxylato ligands and occur predominantly from the carboxylato trans to N. Consistent with this, a computational study reveals that the lowest singlet and triplet LMCT excited states result from electronic transitions to a dσ* orbital distributed along the N−Pt−O axis, which would trigger the observed processes.
