From stem cells to cancer: novel methods for tracking clonal behavior and tumour heterogeneity
[eng] Hematopoietic stem and progenitor cells serve as a cornerstone of tissue homeostasis, enabling the generation of diverse blood cell types and immune responses. However, aberrations in their clonal dynamics and ...
Deciphering the role of the Arabidopsis thaliana METACASPASE I (AtMC1) as a stress granule protein in proteotoxic stress responses
[eng] Rising temperatures pose a significant challenge for plant growth, metabolism, and productivity worldwide. One of the most detrimental consequences of heat stress is the accumulation of misfolded proteins into ...
Impacte de les condicions preanalítiques en la determinació immunohistoquímica del marcador PD-L1
[cat] INTRODUCCIÓ: El PD-L1 és una molècula de superfície que poden expressar determinades cèl·lules tumorals per eludir el control immune de l’organisme. S'han desenvolupat fàrmacs que tenen PD-L1 com a diana terapèutica, ...
Análisis de las Características Multidimensionales de los Pacientes Crónicos Complejos y sus Cuidadores Principales Informales en Atención Primaria.
[spa] Según la Organización Mundial de la Salud (OMS), las enfermedades crónicas son la principal causa de muerte a nivel mundial. Estas enfermedades son de larga duración y generalmente de progresión lenta; además, comportan ...
Research and development of a new biocontrol agent against the foliar diseases downy and powdery mildews in cucurbit crops
[eng] This doctoral thesis explores the initial phases of the development of a new phytosanitary product aimed at combating fungal diseases mildew (Pseudoperonospora cubensis) and powdery mildew (Podosphaera fusca) in ...
Mecanismos de aclimatación a la sequía extrema en especies tolerantes al estrés
[spa] La sequía ejerce un estrés abiótico en las plantas, causando un déficit hídrico que, de ser severo y/o prolongado, puede comprometer su estado fisiológico. Por lo tanto, la aclimatación a la sequía es esencial para ...
Advanced Transition Metal Oxide Nanomaterials for Energy Technologies
[eng] Transition metal oxides (TMOs) are compounds formed from transition metals and oxygen, known for their complex and versatile structures, including diverse crystal forms and multiple oxidation states. This versatility ...
Few Interacting Particles in Low-Dimensional Quantum Systems: From Harmonic Oscillators to Fractal Lattices
[eng] Quantum mechanics is a fascinating field to explore, where its effects are usually non- trivial and counterintuitive. In this Thesis, we focus on systems with a small number of particles in low dimensions, where the ...
Enhanced Optical Response in Arrays of Multifunctional Plasmonic Nanostructures
[eng] This thesis is devoted to the study of two plasmonic nanostructures that present a 3-fold symmetry, namely, inverted honeycomb lattices of bars and twisted stacks of triskelion nanostructures. These systems are ...
Directed cell migration: forces, shapes, and fluctuations in tissues. From active hydrodynamics to experiments
[eng] This thesis investigates collective cell migration in epithelial tissues, under the framework of active soft matter physics. We model epithelial tissues as active polar fluids, since their components, the cells, have ...
Development of a Neurovascular Microfluidic Model with an Endothelial Barrier-Integrity Sensor for Pharmaceutical Innovation in Neurodegenerative Diseases
[eng] Neurodegenerative diseases represent a significant health challenge, as no cure is currently available. The unique anatomy of the blood-brain barrier, which limits drug delivery to the brain, as well as the lack of ...
High Entropy Materials as Air Cathodes for Robust Zinc-Air Batteries
[eng] This thesis focuses on the development of high-entropy materials (HEMs) as advanced bifunctional catalysts for oxygen evolution reaction (OER) and oxygen reduction reaction (ORR). The study systematically investigates ...
Mathematical determination of nonlinear rheology of biofluids
[eng] Blood viscosity plays a critical role in cardiovascular health, influencing hemodynamic processes and disease states. Accurate and rapid measurement of blood rheological properties is essential for diagnostic and ...
Effective field theory methods at high temperature and chemical potential
[eng] This thesis applies and develops effective field theory methods for the study of plasmas at high temperature and/or density. In the 90s, the theoretical frameworks necessary to study quantum electrodynamics (QED) and ...
Study of DNA-Ion interactions using nanopore translocation and optical tweezers
[eng] This thesis uses two complementary single-molecule techniques, nanopipette microscopy and optical tweezers, to investigate the impact of various monovalent salts at high concentrations in DNA. The thesis begins by ...
New experimental techniques for axion searches in the RADES and BabyIAXO experiments
[eng] Initially proposed as part of the solution to the strong CP problem of the Standard Model of particle physics, axions and axion-like particles appear on several Beyond Standard Model extensions. These pseudoscalar ...
A Comparative Study of Football Disputes Legal Procedure in Spain and Iran
[eng] Sports law encompasses a broad array of legal disciplines that impact the sports industry. It addresses issues pertaining to professional and Olympic athletes, as well as those involving youth and amateur sports. The ...
La Asegurabilidad y el Aseguramiento de la responsabilidad por déficit concursal mediante el seguro de D&O
[spa] Legalmente, y de forma progresiva, se han ido ampliando los supuestos de responsabilidad de los administradores, configurando regímenes especiales tan relevantes como el de la responsabilidad por déficit concursal, ...
