Interspecies interactions mediated by conductive minerals in the sediments of the ferruginous Lake La Cruz, Spain
2018
AbstractLake La Cruz is considered a biogeochemical analogue to early Earth marine environments because its water column is depleted in sulfate, but rich in methane and iron, similar to conditions envisaged for much of the Precambrian. In this early Earth analogue environment, we show that conductive particles establish a tight metabolic coupling between electroactive microbial clades. We propose that mineral-based syntrophy is of potential relevance for the evolution of Earth’s earliest complex life forms. We show that the anoxic sediment of Lake La Cruz, which is rich in biogeochemically ‘reactive’ iron minerals, harbors known electroactive species such asGeobacterandMethanothrix,in addit…
Brevi note comparatistiche in tema di suicidio assistito
2019
The essay focuses on the legitimacy of assisted suicide in Italy and in England and Wales, particularly with regard to patients suffering from severe pain from incurable or terminal illnesses. In two recent cases (Cappato and Nicklinson), both Italian and English judges suggested to the Parliament to modify the current state of the law, without making a declaration of incompatibility with Article 8 of the Convention. The paper compares the approach of Corte Costituzionale and UK Supreme Court to the issue, revealing the ambiguity hidden behind those common decisions.
Il fine vita e il legislatore pensante. Il punto di vista dei comparatisti - Parte II
2021
The essay deals with the theme of the end of life within the Italian legal system in comparison with that of other foreign legal systems. In particular, the research addresses the issue of the precautionary tools that the civil process offers to those who ask to end their own life, in the absence of intervention by the competent authorities.
Il fine vita e il legislatore pensante: I minori e la volontà di farla finita
2021
The essay explores the possibility that, in the future, Italian law might consider children and adolescents as subjects eligible to controversial practices such as euthanasia or assisted suicide, widening the limits drawn by the Constitutional Court in the sentence n. 242/2019. The national and European legal frameworks allow estimating, under a comparative perspective, the low probability that such legislation will be enacted in Italy
Biological indices applied to benthic macroinvertebrates at reference conditions of mountain streams in two ecoregions (Poland, the Slovak Republic)
2013
The study was carried out from 2007 to 2010 in two ecoregions: the Carpathians and the Central Highlands. The objectives of our survey were to test the existing biological index metric based on benthic macroinvertebrates at reference conditions in the high- and mid-altitude mountain streams of two ecoregions according to the requirements of the EU WFD and to determine which environmental factors influence the distribution of benthic macroinvertebrates. Our results revealed statistically significant differences in the values of the physical and chemical parameters of water as well as the mean values of metrics between the types of streams at the sampling sites. RDA analysis showed that the t…
Directionnalité graphique et dominance manuelle : une perspective développementale et interculturelle
2012
In the present work, we try to provide some understanding about the factors underlying the directional tendencies, by examining the impact of biomechanical constraints and cultural habits on directionality in graphic movements. French and Syrian subjects, children and adults, were compared in six experiments in order, to put in evidence the cognitive and psychomotor differences caused by the fact that the Eastern and Western cultures oppose on the directionality of writing and reading habits, and that the two hands are opposite in the directionality by adopting movements determined by biomechanical constraints. Likewise, this comparison allowed us to determine the relative strength of these…
Monofunctional pyrenes at carbon nanotube electrodes for direct electron transfer H2O2 reduction with HRP and HRP-bacterial nanocellulose
2021
Abstract The non-covalent modification of carbon nanotube electrodes with pyrene derivatives is a versatile approach to enhance the electrical wiring of enzymes for biosensors and biofuel cells. We report here a comparative study of five pyrene derivatives adsorbed at multi-walled carbon nanotube electrodes to shed light on their ability to promote direct electron transfer with horseradish peroxidase (HRP) for H2O2 reduction. In all cases, pyrene-modified electrodes enhanced catalytic reduction compared to the unmodified electrodes. The pyrene N-hydroxysuccinimide (NHS) ester derivative provided access to the highest catalytic current of 1.4 mA cm−2 at 6 mmol L−1 H2O2, high onset potential …
Electrochemical probe for the monitoring of DNA-protein interactions.
2010
Self-assembly of thiol-terminated oligonucleotides on gold substrates provides a convenient way for DNA-functionalized surfaces. Here we describe the development of an electrochemical assay for the detection of DNA-protein interactions based on the modification of the electrochemical response of methylene blue (MB) intercalated in the DNA strands. Using a functionalized electrode with double stranded DNA carrying T3 RNA polymerase binding sequence, we show a substantial attenuation of the current upon the DNA-protein interaction. Moreover, a Langmuir binding isotherm for T3 RNA polymerase (T3 Pol) gives a dissociation constant K(D) equal to 0.46+/-0.23 microM. Such value is 100 times lower …
