Nitensidine A, a guanidine alkaloid from Pterogyne nitens, is a novel substrate for human ABC transporter ABCB1.

2014

The Pterogyne nitens (Fabaceae) tree, native to South America, has been found to produce guanidine alkaloids as well as bioactive flavonols such as kaempferol, quercetin, and rutin. In the present study, we examined the possibility of interaction between human ATP-binding cassette (ABC) transporter ABCB1 and four guanidine alkaloids isolated from P. nitens (i.e., galegine, nitensidine A, pterogynidine, and pterogynine) using human T cell lymphoblast-like leukemia cell line CCRF-CEM and its multi-drug resistant (MDR) counterpart CEM/ADR5000. In XTT assays, CEM/ADR5000 cells were resistant to the four guanidine alkaloids compared to CCRF-CEM cells, although the four guanidine alkaloids exhibi…

Cytotoxicity of the indole alkaloid reserpine from Rauwolfia serpentina against drug-resistant tumor cells.

2015

Abstract Background: The antihypertensive reserpine is an indole alkaloid from Rauwolfia serpentina and exerts also profound activity against cancer cells in vitro and in vivo. The present investigation was undertaken to investigate possible modes of action to explain its activity toward drug-resistant tumor cells. Material and methods: Sensitive and drug-resistant tumor cell lines overexpressing P-glycoprotein (ABCB1/MDR1), breast cancer resistance protein (ABCG2/BCRP), mutation-activated epidermal growth factor receptor (EGFR), wild-type and p53-knockout cells as well as the NCI panel of cell lines from different tumor origin were analyzed. Reserpine's cytotoxicity was investigated by res…

Cytotoxicity of cucurbitacin E from Citrullus colocynthis against multidrug-resistant cancer cells

2019

Abstract Background Cucurbitacin E (CuE) is an oxygenated tetracyclic triterpenoid isolated from the fruits of Citrullus colocynthis (L.) Schrad. Purpose This study outlines CuE's cytotoxic activity against drug-resistant tumor cell lines. Three members of ABC transporters superfamily, P-glycoprotein (P-gp), breast cancer resistance protein (BCRP) and ABCB5 were investigated, whose overexpression in tumors is tightly linked to multidrug resistance. Further factors of drug resistance studied were the tumor suppressor TP53 and the epidermal growth factor receptor (EGFR). Methods Cytotoxicity assays (resazurin assays) were used to investigate the activity of Citrullus colocynthis and CuE towar…

Ricerche in tema di società questuarie

2019

Intorno al regime delle società di tipo questuario – riconducibili agli schemi teorici della societas universorum quae ex quaestu veniunt – e delle società unius alicuius negotiationis e unius rei, si profusero gli sforzi interpretativi dei giuristi romani, fin dalla fine dell’età repubblicana. La monografia scientifica ripercorre le tracce della individuazione della nozione stessa di quaestus (guadagno), con particolare riferimento alla inclusione al suo interno delle donazioni cd. remuneratorie; ancora, ricostruisce il dibattito giurisprudenziale sorto intorno alla questione se i soci – nella determinazione delle quote – dovessero rispettare una proporzione rispetto ai conferimenti, con u…

About the regulations of the societas quaestus - referable to the societas universorum quae ex quaestu veniunt and to the societas unius alicuius negotiationis and unius rei - the interpretative efforts of the Roman jurists were given profusely since the end of the republican age. The scientific monograph puts itself on the traces of identifying the notion of quaestus (gain) with particular reference to the inclusion within it of the so-called remuneration gifts. Furthermore it reconstructs the jurisprudential debate that aroses around the question of whether the socii - in the determination of the shares - had to respect a proportion with the contributions and in this sense with an attempt to explain the existing contrast between a passage from the Digest and one of the Iustiniani Institutiones. Moreover always with specific reference to the societas quaestus the monograph investigates the setting-up of the intempestiva renuntiatio supporting its origin out of the contrast between Proculiani and Sabiniani so far postulated in doctrine. Finally the book closes with a chapter dedicated to the genesis of the term egestas which appears in a fragment of Modestinus (D. 17.2.4.1) dedicated to the causes of dissolution of the societas consensu contractaSettore IUS/18 - Diritto Romano E Diritti Dell'Antichita'

Plan S: challenges and opportunities in Spain

2019

Spain is one of the most active European countries in the open access (OA) movement. Although the gold route has scarcely been used, the green route has been intensively implemented through fulfilment of European and national mandates and the development of institutional policies. Plan S is becoming a disruptive element in the context of scientific communication, and Spain’s possible adherence to Plan S could imply technical challenges in journals and repositories, additional costs that are difficult to estimate, or refusal to accept the Plan on the part of researchers (based on the loss of freedom to choose the journal in which to publish). However, the implementation of Plan S in Spain wo…

The value of accessibility in the culturalandcreative industries Translation-driven settings

2020

The accessibility of Cultural Creative Industries(CCI) has grown exponentially in different parts of the globe and has increasingly become part of projects of significant importance in contemporary societies that rely on informational, global, and networked systems of communication, i.e., developed countries. CCI exist within public-domain areas and are stimulated by the critical rethinking of the means which can be used to support cultural development. CCI are in fact driven by structures of the knowledge-based economy, where information, originality, and creativity contribute to providing stimuli to their rise. Their emergence is the result of advances in cultural spheres and movements, a…

Attitudes of elementary school teachers towards inclusive education in Ecuador

2020

Resumen Las actitudes de los docentes hacia la inclusión son un factor relevante para permitir que las políticas educativas inclusivas puedan materializarse verdaderamente en prácticas inclusivas. Estas actitudes se ven influenciadas por diferentes variables, entre las que se encuentran la formación y experiencia en el ámbito de la inclusión y las condiciones y recursos disponibles para llevar a cabo prácticas educativas. El objetivo del presente trabajo es analizar las actitudes hacia la inclusión educativa en una muestra de 66 docentes de 15 centros educativos de la ciudad de Cuenca (Ecuador), mediante una escala tipo Likert de 23 ítems. Los resultados muestran que los docentes presentan …
