Curcumin entrapped into lipid nanosystems inhibits neuroblastoma cancer cell growth and activates Hsp70 protein

2010

Curcumin is a natural anti-cancer compound utilized on a wide variety of human cancer cell lines and animal carcinogenesis models. However, its clinical application has been limited for its minimal systemic bioavailability. Nanoparticle-based drug delivery approaches have the potential for rendering hydrophobic molecules such as curcumin dispersible in aqueous media, thus overtaking the limits of its poor solubility. In this paper, we reported the preparation and chemical-physical characterization of Nanostructured Lipid Carriers (NLC) containing curcumin, based on Imwitor, Compritol or Precirol as lipid matrix. By in vitro experiments, we have demonstrated that these nano-systems are able …

2021

Measurement has always been a tool by which we can observe the world around us. This concept was once again confirmed during the 24th IMEKO Technical Committee 4 (TC4) International Symposium, which showed how topics related to the world of measurement range across many fields of knowledge. The IMEKO TC4 International Symposium is one of the most important events in the fields concerned with the theoretical and practical aspects of the measurement of electrical quantities and related instrumentation. It involves institutions and academia in a discussion of the state of the art and issues that require a joint approach by engineers, academics and other experts of measurement, instrumentation,…

How Circular Dichroism in Time- and Angle-Resolved Photoemission Can Be Used to Spectroscopically Detect Transient Topological States in Graphene

2020

Pumping graphene with circularly polarized light is the archetype of light-tailoring topological bands. Realizing the induced Floquet-Chern-insulator state and demonstrating clear experimental evidence for its topological nature has been a challenge, and it has become clear that scattering effects play a crucial role. We tackle this gap between theory and experiment by employing microscopic quantum kinetic calculations including realistic electron-electron and electron-phonon scattering. Our theory provides a direct link to the build up of the Floquet-Chern-insulator state in light-driven graphene and its detection in time- and angle-resolved photoemission spectroscopy (ARPES). This approac…

Entrepreneurship in the Middle East and North Africa: A Bibliometric Analysis

2018

Bibliometrics is an important field of information science that enables bibliographic material to be studied quantitatively. Using bibliometric techniques, this chapter offers an overview of entrepreneurship research in the Middle East and North Africa. Using the Web of Science and Scopus databases, we identify the most relevant research in this field, classified by the most influential authors and the top papers, journals and countries. The sample includes 657 articles published from 1963 to 2016, from 387 different sources. The findings show that studies addressing this topic have been published mainly in non-JCR-indexed journals. In contrast, it is important to note that the top papers (…

Relevance of Big Data for Business and Management. Exploratory Insights (Part I)

2018

Abstract Over the last few decades Big Data has impetuously penetrated almost every domain of human interest/action and it has (more or less consciously) become a ubiquitous presence of day to day life. The main questions this exploratory paper seeks to address (throughout its two parts) are the following: What is the (actual) impact of Big Data on Business & Management and How can businesses (through their management) leverage the potential of Big Data to their benefit? A gradual, step by step approach (based on literature review and a variety of secondary data) will guide the paper in search for answers to the abovementioned questions: starting with a concise history of the topic Big …

Scientific production in bioethics in Spain through MEDLINE

2007

Fundamento: Describir la producción científica española en bioética entre 1966 y 2003. Métodos: Se seleccionaron los documentos publicados por autores españoles y recogidos en la base de datos MEDLINE, mediante el cruce de las palabras bioética con otras diversas del mismo ámbito. Resultados: Se estudiaron 858 documentos, de los cuales 78 (9,1%) se publicaron entre 1966 y 1983, 163 (19%) entre 1984 y 1993, y 617 (71,9%) entre 1994 y 2003. Los principales temas publicados fueron: legislación y derechos (15,4%) e investigación y comités de ética (13,1%). En el último período se ha observado un aumento significativo de las publicaciones sobre genética y clonación y un descenso sobre las de abo…

National e-resources of Shakespeare translations in Europe: (Dis)assembling the black box

2019

This article discusses the construction, operation and scholarly usefulness of electronic resources of Shakespeare translations. In particular, it offers an overview of several existing European digital resources of Shakespeare translations by singling out trends, challenges and new vistas of research; describing the content, editing policies and functionalities of selected European projects, already in operation or currently assembled; and discussing the aims and major difficulties faced by the researchers, the choice of navigation and search tools, the possibilities of integrating national repositories with other resources and the relation of translation e-resources to adjacent disciplin…
