Knowledge on the biosynthetic pathways of the monoter­pene alkaloids is enormous, but little is known about their mechanism of transporting system from the plant cell. There is not concrete evi­dence confirming the role of ABC transporters in the secretion of monoterpene indole alkaloids (MIAs) in Catharanthus roseus. There­fore, in order to determine the role of different transporting systemsinvolved in the MIAs translocation, we employed…

Diabetes mellitus represents a serious public health problem owing to its global prevalence in the last decade. The causes of this metabolic disease include dysfunction and/or insufficient number of b cells. Existing diabetes mellitus treatments do not reverse or control…

A total of 297 bacterial strains were isolated from five Antarctic sponge species and tested by agarose gel electrophoresis for the presence of plasmid molecules. At least one kind of plasmid was carried by 69 isolates (about 23%). The disc…

The aim of this study was to gain some fundamental knowledge on the thermal degradation pathways of poly(N-vinyl pyrrolidone) using Thermogravimetry coupled with Fourier Transform Infrared Spectroscopy (TG–FTIR) in addition to IR and 1H NMR spectroscopic studies of the partially…

The Caribbean Basin has complex biogeographical and cultural histories that have shaped its highly diverse botanical and cultural landscapes. As a result, the current ethnic composition of the Basin is a heterogeneous mixture including Amerindian, Afrocaribbean and a wide range…

NAC proteins constitute one of the largest groups of plant-specific transcription factors and are known to play essential roles in various developmental processes. They are also important in plant responses to stresses such as drought, soil salinity, cold, and heat,…

Esta investigación enfatiza la importancia del conocimiento matemático del profesorado para garantizar una educación matemática continua. Desde esta perspectiva de continuidad se explora el papel del docente de matemáticas en la transición de primaria a secundaria, un contexto especialmente adecuado…

This essay argues that intellectual historians have overlooked the significance of the return of Euclid’s geometric thought to early-modern Europe. Looking at the period between 1400 and 1800, this essay shows how geometric thought not only penetrated into fundamental areas…

La Gestión del Conocimiento Matemático es una rama de las Ciencias de la Computación cuyo principal objetivo consiste en desarrollar asistentes para…

Nowadays large systems are viewed in terms of the services that they offer and the entities that interact to provide or consume these services. Open multi-agent systems, where agents can enter or leave the system, interact and dynamically form groups…
