Study of the interactions between Broad bean wilt virus 1 and its host plants

Broad bean wilt virus 1 (BBWV-1) is the type member of the Fabavirus genus, in the Secoviridae family. BBWV-1 is worldwide distributed and infects important horticultural and ornamental crops causing considerable economic losses. However, information about the biological and molecular characteristics of BBWV-1 isolates is scarce. BBWV-1 is composed of two molecules of positive single-stranded RNA (ssRNA+) that are separately encapsidated in virions of icosahedral morphology. Each ssRNA+ encodes polyproteins which are processed by proteolytic cleavage into functional peptides. RNA1 (~ 5.8 kb) encodes for one polyprotein that renders proteins involved in viral replication: a protease cofactor…

Iron and virulence in the zoonotic pathogen Vibrio vulnificus

2014

Vibrio vulnificus es un patógeno humano emergente que es autóctono de ecosistemas acuáticos salobres de climas templados, tropicales y subtropicales. La especie se subdivide en 3 biotipos (Bt), de los cuales el Bt2 contiene un grupo de cepas que, además de poder infectar al hombre, pueden causar infecciones en peces. Este grupo es un complejo clonal serológicamente homogéneo que denominamos serovar E o serovar zoonótica (VvBt2SerE). Como patógeno humano, VvBt2SerE causa casos esporádicos de infecciones graves en heridas que pueden derivar en septicemia secundaria en pacientes inmunocomprometidos y como patógeno de peces, brotes o epizootias de una septicemia hemorrágica conocida como vibrio…

IgA-Dominant Infection-Associated Glomerulonephritis Following SARS-CoV-2 Infection

2021

The renal involvement of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been reported. The etiology of kidney injury appears to be tubular, mainly due to the expression of angiotensin-converting enzyme 2, the key joint receptor for SARS-CoV-2; however, cases with glomerular implication have also been documented. The multifactorial origin of this renal involvement could include virus-mediated injury, cytokine storm, angiotensin II pathway activation, complement dysregulation, hyper-coagulation, and microangiopathy. We present the renal histological findings from a patient who developed acute kidney injury and de novo nephrotic syndrome, highly suggestive of acute IgA-domina…

Regional Farmers’ Perception and Societal Issues in Vineyards Affected by High Erosion Rates

2021

We explore the current situation in a viticultural region in Eastern Spain from a holistic and multifaceted research approach, which allowed us to understand the biophysical conditions, economic cost, social impact, and perception of the farmers’ community to the use of catch crops. A survey of the perception of the farmers, and an assessment of the biophysical impact of catch crops (CC) and tillage (C = Control plot) on soil organic matter, bulk density, infiltration capacity (single ring infiltrometer), and runoff generation and soil erosion (rainfall simulation experiments) was carried out. Two representative fields as study sites were selected in Les Alcusses valley, within Els Alforins…

VIOLENZA DI PROSSIMITÀ. CURA PASTORALE E VULNERABILITÀ SOCIALE

2022

Nel capitolo introduttivo vendono spiegate le ragioni scientifiche che collegano il paradigma della violenza di prossimità alle rappresentazioni culturali che orientano comportamenti proattivi e, allo stesso tempo, alle dinamiche relazionali che marginalizzano i soggetti più vulnerabili.

Challenging Transmission Modes of Teaching in Science Classrooms : Enhancing Learner-Centredness through Dialogicity

2017

There is an ongoing reform towards more inquiry-based teaching in school curriculum policy in South Africa. Reform towards more inquiry-based approaches is already integrated in pre-service teacher education programmes. As inquiry-based approaches have been gaining momentum worldwide, there is an increasing concern that dialogic interaction in classroom communication is being neglected. This is especially within teacher-orchestrated classroom interactions that should foster greater learner centredness and thus authentic scientific inquiry. In learner-centred teaching approaches, student contributions should be explicitly taken into account as part of classroom interactions in science. Learn…

Perceived status and value

2017

This article examines how students in a multidisciplinary project-based learning course involving real customers perceive their interactions with their customers. The authors conducted a qualitative study and analysed students’ learning reports by means of a thematic network analysis. The analysis shows how students perceive their status in relation to their customers and how their perceptions of their work affect how they see the value of the projects. The authors consider their empirical findings in the context of the existing literature on university–industry collaboration and thereby summarize different scenarios of the contrasting working practices and priorities in academia and indus…
