Antiproliferative activities of resveratrol and related compounds in human hepatocyte derived HepG2 cells are associated with biochemical cell distur…
2008
International audience; Resveratrol is a well known polyphenol largely produced in grapevine. It is a strong antioxidant and a free radical scavenger. It exhibits several beneficial effects for health including cancer. Resveratrol antioxidant activity is essential in the prevention of chemical-induced cancer by inhibiting initiation step of carcinogenesis process but it is also considered to inhibit cancer promotion and progression steps. While the effects of resveratrol on cancer cells are widely described, the data available on the antiproliferative potential of resveratrol derivatives remain weak. Nevertheless, resveratrol analogs could exhibit stronger potentials than the parent molecul…
Study on the sensitive and selective adsorption voltammetry of vanadium with antipyrylazo III (APA III)
1994
The sensitive and selective adsorption voltammetric determination of the vanadium(V)-antipyrylazoIII complex in HAc-NaAc solution is investigated. The V-complex is strongly adsorbed onto a stationary Hg-electrode and is reduced at a potential more negative than that corresponding to the reduction of its ligand. The conditions for determining vanadium are investigated and the mechanism of the reduction peak of the vanadium complex is discussed, as also the influence of foreign ions on the determination of vanadium. An at least 20-fold excess of foreign ions does not cause any interference. The detection limit is 4×10−10 mol/l V with 3 min enrichment time.

Sievietes militārajā dienestā: Dienējošu sieviešu pieredze vīriešu dominējošā vidē
2021
Militārā joma vēsturiski un sociāli tiek definēta kā tradicionāli vīrišķīga – tā ir, iespējams, viena no arhetipiski vīrišķīgākajām sociālajām struktūrām Rietumu sabiedrībā (Segal 1995). Taču militārajā dienestā un karadarbībā tik un tā sastopamas arī sievietes. Šajā bakalaura darbā pētīta 23 sieviešu pieredze, kuras visas dienē vai dienējušas Kanādas Bruņotajos spēkos (KBS) pēdējo četrdesmit gadu laikā. Šo sieviešu pieredze apkopota daļēji strukturētās intervijās, kas veiktas gan klātienē, gan rakstiskā formātā. Izmantojot Pjēra Burdjē teoriju par maskulīno dominanci un Reivinas Konelas koncepciju par maskulīno hegemoniju, darbā esmu pētījusi, kā sievietes pieredz militāro vidi caur dzimtē…
Internet Related Technologies in the auditing profession: A WOS bibliometric review of the past three decades and conceptual structure mapping
2022
Research on Internet-Related Technologies in the auditing profession has grown substantially over the past three decades; however, it is very fragmented. This study seeks to synthesize and provide a comprehensive overview of the literature. Using bibliometric techniques and content analysis, this study provides an exhaustive overview of the research on Internet-Related Technologies in the auditing profession. The study utilized bibliography from the Web of Science database spanning for three decades from 1990 to 2019. A total of 236 academic documents, written by 478 authors from 102 sources was retrieved and used for the analysis. HistCite and Biblioshiny in R were used to run the citation…
Análisis de señales biomédicas para aplicación de terapias en la fibrilación ventricular cardiaca
2017
La muerte súbita es una muerte natural, inesperada y rápida en un tiempo límite de 24 horas después del comienzo de un proceso patológico. Las causas más comunes de la muerte súbita son las enfermedades Cardiovasculares (ECV) que resultan estar entre las principales causas de muerte en todo el mundo. En 2012, la Organización Mundial de la Salud (OMS) registró 17,5 millones de muertes por ECV, que representan el 31 % de todas las muertes registradas en el mundo . Una de las enfermedades cardiovasculares con mayor mortalidad es la Fibrilación Ventricular (FV), que es una arritmia cardíaca producida por una actividad eléctrica desorganizada del corazón. Durante la FV, los ventrículos se contra…
Acute aortic dissection type A
2012
Abstract Background Acute aortic dissection type A (AADA) is a life-threatening vascular emergency. Clinical presentation ranges from pain related to the acute event, collapse due to aortic rupture or pericardial tamponade, or manifestations of organ or limb ischaemia. The purpose of this review was to clarify important clinical issues of AADA management, with a focus on diagnostic and therapeutic challenges. Methods Based on a MEDLINE search the latest literature on this topic was reviewed. Results from the German Registry for Acute Aortic Dissection Type A (GERAADA) are also described. Results Currently, the perioperative mortality rate of AADA is below 20 per cent, the rate of definitive…
Temporal Trends in Transcatheter Aortic Valve Replacement in France
2017
Background - Transcatheter aortic valve replacement (TAVR) is standard therapy for patients with severe aortic stenosis who are at high surgical risk. However, national data regarding procedural characteristics and clinical outcomes over time are limited. Objectives - The aim of this study was to assess nationwide performance trends and clinical outcomes of TAVR during a 6-year period. Methods - TAVRs performed in 48 centers across France between January 2013 and December 2015 were prospectively included in the FRANCE TAVI (French Transcatheter Aortic Valve Implantation) registry. Findings were further compared with those reported from the FRANCE 2 (French Aortic National CoreValve and Edwa…
