Synthesis and Structure Elucidation of Novel Spirooxindole Linked to Ferrocene and Triazole Systems via [3 + 2] Cycloaddition Reaction

2022

In the present work, a novel heterocyclic hybrid of a spirooxindole system was synthesized via the attachment of ferrocene and triazole motifs into an azomethine ylide by [3 + 2] cycloaddition reaction protocol. The X-ray structure of the heterocyclic hybrid (1″R,2″S,3R)-2″-(1-(3-chloro-4-fluorophenyl)-5-methyl-1H-1,2,3-triazole-4-carbonyl)-5-methyl-1″-(ferrocin-2-yl)-1″,2″,5″,6″,7″,7a″-hexahydrospiro[indoline-3,3″-pyrrolizin]-2-one revealed very well the expected structure, by using different analytical tools (FTIR and NMR spectroscopy). It crystallized in the triclinic-crystal system and the P-1-space group. The unit cell p…

Social psychological aspects of ACL injury prevention and rehabilitation: An integrated model for behavioral adherence

2017

Managing rehabilitation for ACL injury is dependent on uptake of, and compliance with, medical and safety recommendations. In this paper, we propose a multi-theory model that integrates self-determination theory and the theory of planned behavior to identify the motivational determinants ACL injury prevention and management behaviors and the processes involved. nonPeerReviewed

Il ruolo della corteccia prefrontale dorsolaterale nella memoria di riconoscimento: uso dellla Stimolazione Magnetica Transcranica per il trattamento…

Il ruolo della corteccia prefrontale dorsolaterale (DLPFC) in compiti di memoria è stato largamente documentato. Una questione ancora molto dibattuta è il grado di lateralizzazione anatomica-funzionale dei processi di controllo esecutivo della DLPFC coinvolti nella memoria di riconoscimento. Il lavoro di tesi indaga le connessioni tra DLPFC e ippocampo mediante l’applicazione di tecniche di neuromodulazione dell’eccitabilità della DLPFC che consentano di accrescere l’attività ippocampale durante compiti di memoria di riconoscimento. I primi tre studi valutano gli effetti inibitori ed eccitatori della rTMS applicata alla DLPFC sulla performance in compiti di memoria di riconoscimento, in div…

I nomi del male e i segni dell'eredità. Pensare, nominare e curare la malattia "genetica" dai Greci a noi

2019

Il volume indaga le radici storiche delle malattie che oggi definiamo genetiche e/o ereditarie, ponendo le premesse terminologiche e scientifiche che stanno a fondamento della riflessione moderna e contemporanea sulla malattia genetica, qui animata dal filo della continuità e della pur forte discontinuità con il pensiero antico. In tal senso, si presenta una retrospettiva storico-critica che, affondando le proprie radici nell’indagine lessicografica dei termini fondanti il pensiero embriogenetico moderno, interroga la validità storica ed epistemica di alcuni concetti e parole-chiave dell’era post-genomica, tra cui quello di causalità, o il rapporto tra natura e cultura, per toccare il nucle…

Straw as a contemporary biomaterial: energetic efficiency and enviromental sustanaibility

2016

Questo studio ha lo scopo di segnalare ricerche e applicazioni in ambito costruttivo europeo e non solo della paglia, con particolare attenzione all'efficienza energetica e al comfort abitativo. Il riciclo e riutilizzo dei materiali naturali sono gli obiettivi principali nella scelta di paglia come materiale da costruzione, consentendo di adottare un approccio metodologico complessivo, che potrebbe prendere in considerazione l'intero edificio del ciclo di vita. Partendo dalla storia dell'utilizzo di paglia nella costruzione edilizia, saranno riportati molti esempi di edifici che utilizzano tale materiale all'interno del loro involucro e struttura. Le caratteristiche principali della paglia …

Compared Binding Properties between Resveratrol and Other Polyphenols to Plasmatic Albumin: Consequences for the Health Protecting Effect of Dietary …

2014

International audience; Phytophenols are considered to have beneficial effects towards human physiology. They are food microcomponents with potent chemopreventive properties towards the most three frequent contemporary human diseases, e.g., cardiovascular alterations, cancer and neurodegenerative pathologies. Related to this, the plasmatic form and plasmatic level of plant polyphenols in the body circulation are crucial for their efficiency. Thus, determinations of the binding process of resveratrol and of common flavonoids produced by major edible plants, berries and fruits to plasma proteins are essential. The interactions between resveratrol and albumin, a major plasma protein, were comp…

Crystal structure and Hirshfeld surface analysis of [N(CH3)4][2,2′-Fe(1,7-closo-C2B9H11)2]

2017

Abstract This work investigates the meta -ferrabis(dicarbollide) anion that was isolated as salt of tetramethylammonium. The structure of the obtained crystal consisted of discrete [2,2′-Fe(1,7- closo -C 2 B 9 H 11 ) 2 ] − anions and disordered [N(CH 3 ) 4 ] + cations. The anion had a considerable chemical stability ensured by ionic and Van der Waals interactions. Thus, Hirshfeld surfaces and fingerprint plot were used to visualize, explore, and quantify intermolecular interactions in the crystal lattice of the title compound. This investigation proved that close contacts were dominated by H⋯H interactions.

Fanonian analysis of racism and postcolonial structures of othering

2023

The paper explores how boundaries affect the search for identity in the context of racism and colonialism. Colonized individuals often experience a sense of alienation and inferiority caused by the limitations imposed by colonial power structures, leading to a quest for personal identity. However, the binary division between the colonizer and colonized affects everyone involved, making searching for personal identity more complex and reinforcing systemic racism. The first section of the article examines how race, a socially constructed concept, plays a crucial role in defining the difference between oneself and others, impo-sing structures of othering based on Fanonian analysis. The second …

Classical and reverse substituent effects in meta- and para-substituted nitrobenzene derivatives

2017

Electron-accepting properties of the nitro group were studied in a series of meta- and para-X-substituted nitrobenzene derivatives (X = NMe2, NH2, OH, OMe, CH3, H, F, Cl, CF3, CN, CHO, COMe, CONH2, COOH, COCl, NO2, NO). For this purpose Hammett-like approaches were applied based on quantum chemistry modeling; the B3LYP/6-311++ G(d,p) method was used. The substituent effect (SE) was characterized by the mutually interrelated descriptors: the charge of the substituent active region, cSAR(X), and substituent effect stabilization energy, SESE, as well as substituent constants, σ. Classical SE is realized by dependences of the structural parameters of the nitro group (ONO angle and NO bond lengt…

Titanocene Selenide Sulfides Revisited: Formation, Stabilities, and NMR Spectroscopic Properties

2019

[TiCp2S5] (phase A), [TiCp2Se5] (phase F), and five solid solutions of mixed titanocene selenide sulfides [TiCp2SexS5−x] (Cp = C5H5−) with the initial Se:S ranging from 1:4 to 4:1 (phases B–E) were prepared by reduction of elemental sulfur or selenium or their mixtures by lithium triethylhydridoborate in thf followed by the treatment with titanocene dichloride [TiCp2Cl2]. Their 77Se and 13C NMR spectra were recorded from the CS2 solution. The definite assignment of the 77Se NMR spectra was based on the PBE0/def2-TZVPP calculations of the 77Se chemical shifts and is supported by 13C NMR spectra of the samples. The following complexes in varying ratios were identified in the CS2 solutions of …
