Insights into the Mechanism of Anodic N–N Bond Formation by Dehydrogenative Coupling
2017
The electrochemical synthesis of pyrazolidine-3,5-diones and benzoxazoles by N-N bond formation and C,O linkage, respectively, represents an easy access to medicinally relevant structures. Electrochemistry as a key technology ensures a safe and sustainable approach. We gained insights in the mechanism of these reactions by combining cyclovoltammetric and synthetic studies. The electron-transfer behavior of anilides and dianilides was studied and led to the following conclusion: The N-N bond formation involves a diradical as intermediate, whereas the benzoxazole formation is based on a cationic mechanism. Besides these studies, we developed a synthetic route to mixed dianilides as starting m…
Prospective Image Quality and Lesion Assessment in the Setting of MR-Guided Radiation Therapy of Prostate Cancer on an MR-Linac at 1.5 T: A Compariso…
2021
The objective of this study is to conduct a qualitative and a quantitative image quality and lesion evaluation in patients undergoing MR-guided radiation therapy (MRgRT) for prostate cancer on a hybrid magnetic resonance imaging and linear accelerator system (MR-Linac or MRL) at 1.5 Tesla. This prospective study was approved by the institutional review board. A total of 13 consecutive patients with biopsy-confirmed prostate cancer and an indication for MRgRT were included. Prior to radiation therapy, each patient underwent an MR-examination on an MRL and on a standard MRI scanner at 3 Tesla (MRI3T). Three readers (two radiologists and a radiation oncologist) conducted an independent qualita…
Inflammatory Response Mechanisms of the Dentine–Pulp Complex and the Periapical Tissues
2021
The macroscopic and microscopic anatomy of the oral cavity is complex and unique in the human body. Soft-tissue structures are in close interaction with mineralized bone, but also dentine, cementum and enamel of our teeth. These are exposed to intense mechanical and chemical stress as well as to dense microbiologic colonization. Teeth are susceptible to damage, most commonly to caries, where microorganisms from the oral cavity degrade the mineralized tissues of enamel and dentine and invade the soft connective tissue at the core, the dental pulp. However, the pulp is well-equipped to sense and fend off bacteria and their products and mounts various and intricate defense mechanisms. The fron…
Identification and Quantification of Valuable Compounds in Red Grape Seeds
2021
Grape seeds are a by-product of the wine industry. They represent 38–52% of grape pomace and about 5% of the weight of grapes. The main objective of this study is to establish some important characteristics of grape seeds from red varieties cultivated in Romania. The analyzed grape varieties were Cabernet Sauvignon, Merlot, Pinot noir, Burgund Mare, Cadarcă, Syrah, Novac. The grape seeds were dried and ground and the following determinations were made: determination of total polyphenol content, antioxidant capacity, antiradical capacity and determination of phenolic compounds. The analyses were performed on the first day after obtaining the grape extract, on the 14th day and the 30th day. T…
Health coverage for a retreating army: a Medical Captain’s action during the Maestrazgo campaign (April-July 1938).
2012
espanolAntecedentes y objetivos: Tras la entrada definitiva de las tropas del general Franco en la ciudad de Teruel en febrero de 1938 se inicio la retirada progresiva del Ejercito de Maniobra de la republica. El rapido avance de las fuerzas nacionales hacia el Mediterraneo marco las caracteristicas de la cobertura sanitaria militar. El objetivo de este trabajo es realizar una aproximacion a la Sanidad del Ejercito republicano durante su retirada por el Maestrazgo castellonense, que tuvo lugar entre abril y julio de 1938 en el contexto de la Guerra Civil Espanola (1936-1939). Material y metodos: Hemos utilizado una fuente de gran valor historico, como es el testimonio oral de un Capitan Med…
La puissance du regard chez Marie-Claire Blais: de la honte à l’affirmation de soi
2009
-Eva.Pich@uv.es In Marie-Claire Blais’ first novels, the images of eyes and glances acquire a great significance. They highlight the character’s relationships, conformism or rebelliousness. The other’s constant gaze arouses feelings of shame and remorse in the character which is being observed. This article will illustrate how Marie-Claire Blais’ portrayals of eyes and glances allow her to draw attention to the character’s relationships and to denounce the dramatic consequences the notions of guilt and shame have in the search of individual identity. En las primeras novelas de Marie Claire Blais, la mirada adquiere una importancia esencial y pone de relieve las relaciones entre los personaj…
Tras la constitución de 2019 : ¿albores de la responsabilidad parental en cuba?
2021
Tras la Constitución de 2019 se avizora un nuevo horizonte de la responsabilidad parental en Cuba, que nace entre la constitucionalización de los derechos familiares y el reconocimiento constitucional de las garantías procesales como expresión de cambios sociales y corolario del influjo de la internacionalización de las relaciones familiares. A raíz de todo lo cual surge un programa de reformas de las instituciones sustantivas y procesales, que inspirado en el interés superior del niño debe integrar, en modo coherente y sistemático, las orientaciones que descienden del sistema convencional y la axiología que pauta el actual texto constitucional.
Ar amīniem modificētu 1,4-dihidropiridīna atvasinājumu sintēze un īpašību pētījumi
2016
Sintezēts nekomerciāli pieejamais didodecil 2,6-bis(brometil)-4-fenil-1,4-dihidropiridīna-3,5-dikarboksilāts. Tam veikta broma aizvietošana 2,6-vietās ar dažādiem amīniem, iegūstot desmit jaunus oriģinālus savienojumus. Dots jaunsintezēto savienojumu fiziko-ķīmisko īpašību raksturojums, noteikta sintezēto savienojumu reducējošās kapacitātes aktivitāte, izmantojot fosformolibdēna kompleksa metodi, veikta antiradikālās aktivitātes noteikšana ar 1,1-difenil-2-pikrilhidrazil brīvo radikāļu metodi. Noskaidrots, ka no visiem jaunsintezētajiem savienojumiem, visaktīvākais ir didodecil 2,6-bis[(5-fluoro-2,6-diokso-3-tetrahidrofurān-2-il-pirimidīn-1-il)metil]-4-fenil-1,4-dihidropiridīna-3,5-dikarbok…
