1. Modelling collective movement and transport network formation in living systems
Abstract : The emergence of collective patterns from repeated local interactions between individuals is a common feature to most living systems, spanning a variety of scales from cells to animals and humans. Subjects of this thesis are two aspects of emergent complexity in living systems: collective movement and transport network formation. READ MORE

2. The γ-aminobutyric acid and proton signaling systems in the zebrafish brain : Characterization and effect of stress
Abstract : The central nervous system of vertebrates is continuously processing sensory information relayed from the periphery, integrating it and producing outputs transmitted to efferents. In the brain, neurons employ an array of messenger molecules to filter afferent information and finely regulate synaptic transmission. READ MORE

3. Theoretical studies of mononuclear non-heme iron active sites
Abstract : The quantum chemical investigations presented in this thesis use hybrid density functional theory to shed light on the catalytic mechanisms of mononuclear non-heme iron oxygenases, accommodating a ferrous ion in their active sites. More specifically, the dioxygen activation process and the subsequent oxidative reactions in the following enzymes were studied: tetrahydrobiopterin-dependent hydroxylases, naphthalene 1,2-dioxygenase and α-ketoglutarate-dependent enzymes.

4. A Divided Old Age through Research on Digital Technologies
Abstract : This thesis aims at contributing to the understanding of digital inequalities among older people, by studying the involvement of older people in research on digital technologies. Some mechanisms driving old age digital inequalities are well known. READ MORE

5. Pathophysiological effects of alpha-synuclein on SNARE complex proteins in models of alpha-synucleinopathies
Abstract : Accumulation and spread of alpha-synuclein (α-syn) aggregates are central to the disease pathogenesis of Parkinson’s disease and dementia with Lewy bodies, collectively known as α-synucleinopathies. Native α-syn is a monomeric presynaptic protein that can act as a molecular chaperone for the soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) complex assembly. READ MORE
