Adenosine deaminase acting on tRNAs (ADAT) is a eukaryotic heterodimer, composed by ADAT2 and ADAT3, that catalyses the deamination of adenosine-to-inosine in the anticodon loop of tRNAs. ADAT proteins are essential for ...
[eng] We investigated the structure function relationship of PorX by combined biophysical experiments and enzymatic assays. As a regulator of the type 9 secretion system (T9SS) of the human pathogen Porphyromonas gingivalis ...
The mitochondrial transcription factor A, TFAM, has a dual function in the organelle: it activates mitochondrial DNA transcription by binding to the HSP and LSP promoters, while in higher concentrations compacts the mtDNA. ...
This thesis is focused on the implication of de dynamics of clusters on the HI content of galaxies. Target of this study has been the Virgo cluster region.<br/><br/>We have first inferred the three-dimensional galaxy ...
This thesis presents a collection of four papers published in peer-reviewed scientific journals plus a manuscript yet to be submitted, all of them in the field of low temperature physics and quantum fluids. Each of these ...
The role of natural biofilms affecting the water quality in rivers has been the main theme in this study. Firstly, the study developed the capacity of biofilms in retention and/or production of DOC. Secondly, the study ...
[eng] The emergence and spread of antibiotic resistance among bacteria has become an undisputed global problem and one of the greatest threats to public health in the 21st century. The widespread, excessive and uncontrolled ...
Studies of mountain belts worldwide show that along-strike changes are common in their foreland fold-and-thrust belts. These are typically caused by processes related to fault reactivation and/or fault focusing along changes ...
Gamma-ray binaries are extreme systems that produce non-thermal emission from radio to very-high-energy (above TeV) gamma rays, with the energy output in the spectral energy distribution (SED) dominated by the MeV–GeV ...
The main objective of this Ph. D. Thesis work was to study the physicochemical properties of the inner membrane of mitochondria and the interaction of "cyt c" with model membranes. Suitable techniques were used to accomplish ...
In a time when large amounts of data about social, economical, technological, and biological systems are produced in a daily bases, complex networks have become a powerful tool to represent the structure of complex systems. ...
In this report novel materials for advanced applications are studied by means of the latest microscopy technologies and methodologies which have had a dramatic impact on progress of materials science. The aim was to study ...
The thesis research concerned evolutionary ecology and community ecology of amphibians in two different areas of a Mediterranean region. The goal of the research was to test how anuran species coexist along a lentic ...
The study of chromatin structure in several simple sperm models of increasing complexity was performed. Species demonstrating different types of sperm nuclear protein transitions and structural changes in spermatic chromatin ...
From the fundamental point of view, NPs formed by MFe2O4 with (M= Co, Fe) are ideal system models to study the new magnetic phenomena associated with the so-called particle-like behaviour, which emerges from the size ...
The common scope of this thesis is the application of structural biology and biophysics to obtain novel data on nuclear proteins that modulate DNA transcription. The proper regulation and functioning of these elements are ...
Prostate cancer (PCa) is the second most common cancer in men after lung cancer. Around 1.1 million men worldwide were diagnosed with PCa in 2012. PCa depends essentially on androgen stimulation for growth and cell survival. ...
Viruses are submicroscopic biological entities that need to infect a host cell in order to replicate. In their simplest form viruses are constituted by an infective genetic material and a protein shell (the capsid) that ...
Molt is the process of plumage renewal by which birds maintain and adjust its functionality throughout their lifecycle. Multiple elements have been tackled in bird molt research (timing, duration, sequence, intensity, ...
The herpesvirus diseases are increasing in importance as a public health problem throughout the world. Members of the human herpesvirus family are global in distribution and infect 60-95% of the world's population, both ...
