orthoeffect on the nitrosation of the 2,3-diphenyl-5(2-methoxyphenyl)pyrrole

1990

A comparison of the behaviour on the nitrosation of the isomers 5-(2-methoxyphenyl)- (1a) 5-(3-methoxyphenyl)- (1b) and 5-(4-methoxyphenyl)2,3-diphenylpyrroles (1c) carried out in the usual way with iso-amyl nitrite in a solution of sodium ethoxide in ethanol evidences that 1a is dramatically less reactive with respect to 1b and 1c. The different reactivity was ascribed to the occurrence of a strong hydrogen bond involving pyrrole NH and the ortho-methoxy group.

Involvement of Peroxynitrite on the Early Loss of P450 in Short-Term Hepatocyte Cultures

2001

The biological chemistry of nitric oxide (NO) in the oxygenated cellular environment is extremely complex. It involves the direct interaction of NO with specific biomolecules and the so-called indirect effects, due to secondary more potent oxidant species derived from NO which are also able to react with DNA, lipids, thiols and transition metals (Wink et al. 1996; Nathan, 1992). In addition to its regulatory role as a signalling molecule (Nathan, 1992; Moncada and Palmer, 1991) it has become evident that NO (or NO-derived species) is a critical factor involved in various toxicological mechanisms (Wink et al. 1996; Wang et al. 1998; Estevez et al. 1999; Wink et al. 1999). Some controversy ex…

Synthesis of new 2,2′-disubstituted 5,5′-dimethyl-4,4′-bitriazoles and 2-(4-Triazolyl)quinoxalines

2000

Thermal rearrangement of 3-acylisoxazole arylhydrazones allowed facile preparation of 2H-1,2,3-triazoles which were firstly reacted with isoamyl nitrite and then with an opportune arylhydrazine to produce the corresponding α-hydroxyiminohydrazones 8a-h. The reaction of compounds 8a-h with phosphorus pentachloride afforded the desired 4,4′-bitriazoles 1a-h. The α-hydroxyiminoketone derivative 7 or the α-diketone 14 reacted easily with 1,2-phenylenediamine to afford 1,2,3-triazoles 2a-c bearing the quinoxaline moiety at position 4. Improved yields of the quinoxalines 2a-c were obtained when 1,2-phenylenediamine was reacted with the dioxime 15.

Photocatalytic oxidation of cyanide in aqueous TiO2 suspensions irradiated by sunlight in mild and strong oxidant conditions

1999

Abstract The photocatalytic oxidation of free cyanide ions was carried out in aqueous aerated suspensions containing polycrystalline TiO2 (anatase) irradiated by sunlight. The influence of the presence of an organic compound (phenol) or of a strong oxidant (H2O2) on the photoprocess was also studied. The dependence of cyanide photo-oxidation rate on the following parameters: (1) cyanide concentration; (2) catalyst amount; and (3) phenol concentration was investigated. At the used experimental conditions, the kinetics of cyanide photo-oxidation is independent of the initial cyanide concentration and of the catalyst amount while it is affected by the phenol concentration and by the presence o…

Polymerisation von acrylnitril, methylmethacrylat und einigen substituierten acrylnitrilen mit anorganischen nitraten. Zur polymerisation von acryini…

1968

Die radikalische Polymerisation von Acrylnitril (AN), Methacrylnitril, α-Chloracrylnitril, Crotonsaurenitril und Methylmethacrylat wird unter Bestrahlung bei 60°C in An wesenheit von AgNo3 untersucht, und die Polymerisationsgeschwindigkeiten werden verglichen. Unterschiede in der Polymerisationsfahigkeit einzelner Monomerer lassen sich teilweise auf Komplexbildung mit AgNO3 zurackfahren. Es werden einige andere anorganische Nitrate als Initiatoren eingesetzt; ihre Aktivitat entspricht der Stellung der Kationen in der Spannungsreihe. Als Teil der Initiierungsreaktion wird eine Reduktion des Metallions angenommen; daher kann eine Abnahme der Kationenkonzentration bei AgNO3 und besonders bei C…

This record contains data related to article “Chronic inflammatory demyelinating polyradiculoneuropathy: can a diagnosis be made in patients not fulfilling electrodiagnostic criteria?" Abstract Background and purpose: The aim was to identify the clinical and diagnostic investigations that may help to support a diagnosis of chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) in patients not fulfilling the European Federation of Neurological Societies and Peripheral Nerve Society (EFNS/PNS) electrodiagnostic criteria. Methods: The data from patients with a clinical diagnosis of CIDP included in a national database were retrospectively reviewed. Results: In all, 535 p…

Kompensācija cietušajam par nodarīto kaitējumu kriminālprocesā

2015

Mūsdienās aizvien ir aktuāla morālā kaitējuma kompensācijas noteikšana kriminālprocesā, it sevišķi tāpēc, ka morālam kaitējumam nepastāv precīzi nosakāms naudas ekvivalents. Darba mērķis ir izveidot universālu, ilgspējīgu morālā kaitējuma noteikšanas koncepciju, skaidri noteikt kritērijus, kuri tiesnešiem jāņem vērā, lemjot par kaitējuma kompensācijas apmēru, turklāt izpētīt arī praktiskos jautājumus, kas saistās ar kompensācijas pieteikšanu. Pētījuma rezultātā izstrādāta ilgspējīga morālā kaitējuma koncepcija, kurā noteikti rekomendējoši, taču aptuveni kompensācijas piešķiršanas apmēri, kā arī piedāvāti vairāki Kriminālprocesa likuma grozījumi.

La catena del valore nelle organizzazioni produttive di servizi. Il capitale sociale della città

2005

The urban unity-difference, formed of the social community interacting with the human, natural and constructed environments, produces private and social values or benefits. Interactions among the "services supplying urban firm" and the social, economic and natural environments produce value flows that dinamically form and exchange in the value chain. The New Economics approach is used to analyze the functioning principles of such a kind of value chain. Moreover, the application of a multicriterial operational model for the valuation of variations of social capital produced by every kind of private o public "firm-market system" is outlined. The subject is rilevant: in the public decisional c…

Nonverbal synchrony in couple therapy linked to clients’ well-being and the therapeutic alliance

2021

Nonverbal synchrony between individuals has a robust relation to the positive aspects of relationships. In psychotherapy, where talking is the cure, nonverbal synchrony has been related to a positive outcome of therapy and to a stronger therapeutic alliance between therapist and client in dyadic settings. Only a few studies have focused on nonverbal synchrony in multi-actor therapy conversations. Here, we studied the synchrony of head and body movements in couple therapy, with four participants present (spouses and two therapists). We analyzed more than 2000min of couple therapy videos from 11 couple therapy cases using Motion Energy Analysis and a Surrogate Synchrony (SUSY), a procedure us…
