Neuromuscular and hormonal adaptations to resistance training : special effects of time of day of training
2009
The majority of the processes in human physiology and behaviour exhibit daily variation. Neuromuscular performance has been repeatedly shown to be lower in the morning hours compared to the rest of the day. However, the scientific data available provide somewhat conflicting results on the origin and mechanisms of diurnal variation in maximum strength and power. In addition, very limited scientific evidence exists as to whether this diurnal variation can be diminished by time-of-day-specific resistance training.The present study was designed to obtain more information on the mechanisms behind both diurnal variation in muscle strength and power, and the mechanisms behind adaptations to time-o…
Drought Stress Study on Nicotiana tabacum L., “Baladi”, an In Vitro Experimental Model
2021
Crops drought tolerance is a trait of outmost importance for agriculture especially today when climate change is affecting more the production for food and feed. The scope of this article is to evaluate in vitro drought stress response of Nicotiana tabacum L., “Baladi”. The experiment was set up for four successive stages starting with in vitro seedling development, hypocotyl cultivation, three generations of micropropagation, pre-acclimatization and acclimatization. The effect of abscisic acid (ABA) and/or polyethylene-glycol 6000 (PEG) on tobacco hypocotyl caulogenesis and micropropagation were investigated. Superoxide-dismutases (SODs) and peroxidases (POXs) are more active and different…
La federazione italiana gioco calcio è un organismo di diritto pubblico? Il vaglio della Corte di giustizia
2021
l presente contributo affronta il tema della inquadrabilità della Federazione Italiana Gioco Calcio nell’ambito della figura dell’organismo di diritto pubblico, prendendo spunto da una recente sentenza della Corte di giustizia e dai quesiti ad essa posti dalle ordinanze di rinvio del Consiglio di Stato. Tra ordinanze di rinvio, Conclusioni dell’Avvocato generale e giudizio della Corte emergono i tratti essenziali del particolare rapporto tra federazioni sportive e CONI, oltre che importanti precisazioni su ciò che debba essere inteso per vigilanza sulla gestione delle federazioni (vigilanza come controllo attivo, idoneo a influire sulle decisioni delle federazioni stesse in materia di appal…

Palliative Care and End-of-Life Issues in Patients with Brain Cancer Admitted to ICU
2023
Background and Objectives: Palliative care is an interdisciplinary medical specialty focused on improving the quality of life of critically ill patients, including those with frailty, during their illness. Materials and Methods: We conducted an extensive literature review on Pubmed focusing on palliative care in neuro-oncology patients admitted to intensive care units (ICUs). Results: We identified 967 articles and, after excluding 952 articles in accordance with the PRISMA flow chart, we included a total of 15 articles in the final selection. The potential role of palliative care in neuro-oncology appears necessary to ensure comprehensive end-of-life patient care. However, this seems under…
Chirality selective spin interactions mediated by the moving superconducting condensate
2018
We show that superconducting correlations in the presence of nonzero condensate velocity can mediate the peculiar interaction between localized spins that breaks the global inversion symmetry of magnetic moments. The proposed interaction mechanism is capable of removing fundamental degeneracies between topologically distinct magnetic textures. For the generic system of three magnetic impurities in the current-carrying superconductor, we find the energy term proportional to spin chirality. In realistic superconductor/ferromagnetic/superconductor setups we reveal significant energy differences between various magnetic textures with opposite chiralities. We calculate Josephson energies of junc…
Field dependence of the vortex-core sizes in dirty two-band superconductors
2019
We study the structure of Abrikosov vortices in two-band superconductors for different external magnetic fields and different parameters of the bands. The vortex core size determined by the coherence lengths are found to have qualitatively different behaviour from that determined by the quasiparticle density of states spatial variation. These different vortex core length scales coincide near the upper critical field, while the discrepancy between them becomes quite significant at lower fields. Within the diffusive approximation we demonstrate several generic regimes in the field dependence of the vortex core sizes determined by the disparity of diffusion constants in the two bands.

Influencing the self‐sorting behavior of [2.2]paracyclophane based ligands by introducing isostructural binding motifs
2020
Two isostructural ligands with either nitrile ( L nit ) or isonitrile ( L iso ) moieties directly connected to a [2.2]paracyclophane backbone with pseudo‐meta substitution pattern have been synthesized. The ligand itself ( L nit ) or its precursors ( L iso ) were resolved via HPLC on a chiral stationary phase and the absolute configuration of the isolated enantiomers was assigned by XRD analysis and/or by comparison of quantum‐chemical simulated and experimental ECD‐spectra. Surprisingly, the resulting metallosupramolecular aggregates formed in solution upon coordination of [(dppp)Pd(OTf) 2 ] differ in their composition: whereas L nit forms dinuclear complexes L iso exclusively forms trinuc…
