Roa Rovira, Joan Josep (Date of defense: 2010-04-16)
The nanoindentation or indenter testing technique (ITT) is a functional and fast technique that can give us a lot of information about the mechanical properties of different materials at nanometric scale, from soft to ...
Morais Leitão de Almeida, Bruno Alexandre (Date of defense: 2022-05-26)
[eng] INTRODUCTION: Peri-implantitis is an inflammatory condition that affects soft and hard tissues around dental implants and that can lead to implant failure. Implantoplasty is a procedure that allows implant surface ...
Tsioutsios, Ioannis (Date of defense: 2016-07-26)
Los resonadores mecánicos basados en grafeno y nanotubos de carbono han atraído recientemente una considerable atención, debido a la gran variedad de propiedades extraordinarias que exhiben. La reducida dimensión intrínseca ...
Marín Llauradó, Ariadna (Date of defense: 2022-01-27)
GENERAL AIM: The general aim of this thesis is to understand how mechanical stress depends on pressure, size and shape in fluid-filled curved epithelial sheets. SPECIFIC AIMS: This general aim can be divided ...
Hernández Vega, Amayra Noemi (Date of defense: 2015-10-05)
Epithelial layers constitute the skeleton of early embryos and most tissues and organs and their remodelling during development is essential for reshaping the embryo and for tissue architecture. Epithelial expansion in ...
Rodríguez Franco, Pilar (Date of defense: 2017-01-20)
For an organism to develop and maintain homeostasis, cell types with distinct functions must often be separated by physical boundaries. The formation and maintenance of such boundaries is commonly attributed to local ...
Chahare, Nimesh Ramesh (Date of defense: 2023-06-20)
(English) Epithelial sheets form specialized 3D structures suited to their physiological roles, such as branched alveoli in the lungs, tubes in the kidney, and villi in the intestine. To generate and maintain these structures, ...
Kłosin, Adam (Date of defense: 2015-11-09)
Desde Darwin y Lamarck, a los biólogos les ha intrigado la posibilidad de que rasgos adquiridos debido al ambiente pudieran ser heredados. Se han descrito muchos ejemplos de este tipo debidos a perturbaciones del ambiente ...
Comolli, Alessandro (Date of defense: 2018-06-14)
Solute transport in heterogeneous porous media in general exhibits anomalous behaviors, in the sense that it is characterized by features that cannot be explained in terms of traditional models based on the advection-dispersion ...
Díaz i Cirac, Anna (Date of defense: 2011-07-01)
This PhD thesis is the result of the combination of experimental and computational techniques with the aim of understanding the mechanism of action of de novo cyclic decapeptides with high antimicrobial activity. By ...
Scrofani, Jacopo (Date of defense: 2014-10-10)
During mitosis, spindle assembly involves different sources of microtubules including centrosomes and chromosomes. While the role of centrosomes has been extensively studied, we still do not fully understand how chromosomes ...
Macías Ribela, Sara (Date of defense: 2008-06-13)
The mechanisms of pre-mRNA splicing regulation are poorly understood. Here we dissect how the Saccharomyces cerevisiae ribosomal L30 protein blocks splicing of its pre-mRNA upon binding a kink-turn structure including the ...
González del Solar Sarría, Rafael (Date of defense: 2016-01-25)
La ecología es una ciencia importante, tanto desde el punto de vista práctico como desde el teórico, que recientemente a comenzado a atraer la atención de los filósofos profesionales. Con todo, la investigación sobre los ...
Venturini, Valeria (Date of defense: 2022-04-08)
Living tissues are crowded and dynamic environments, in which signalling molecules and physical forces constantly act on single cells. To ensure correct tissue development and homeostasis, cells function like small processors: ...
Barbero Castillo, Almudena (Date of defense: 2020-07-17)
Throughout various brain states, billions of neurons interact resulting in a variety of cortical rhythms accompanied by switches between behavioral states (Gervasoni et al., 2004). As a result of the specific (1) ...
Mateu Jiménez, Mercè (Date of defense: 2017-12-18)
Chronic respiratory diseases, especially chronic obstructive pulmonary disease (COPD), and several molecular mechanisms may predispose to lung cancer (LC) development. Hypothesis: We hypothesized that different biological ...
Bernadó Morales, Cristina (Date of defense: 2015-04-23)
In response to oncogenic stresses cells activate two different tumor suppressor mechanisms: Oncogene-induced senescence (OIS), a terminal cell proliferation arrest, or oncogene-induced apoptosis (OIA), which leads to cell ...
Banakar, Raviraj (Date of defense: 2016-02-05)
L’arròs es un cultiu bàsic, consumit per mes de 3 billons de persones. Es una font pobra en ferro (Fe) i zinc (Zn) per la qual cosa les poblacions pobres que depenen de l’arros per a la seva supervivència, sofreixen d’anèmia ...
Souza, Vitor Barbosa Carlos de (Date of defense: 2018-01-10)
Albeit several IoT applications have been recently deployed in several fields, including environment and industry monitoring, Smart Home, Smart Hospital and Smart Agriculture, current deployments are mostly host-oriented, ...
Tanovic, Adnan (Date of defense: 2003-06-13)
El objetivo de este estudio es evaluar los mecanismos neurales y musculares implicados en la contracción y la relajación del músculo longitudinal del intestino delgado de rata en condiciones control y tras la infestación ...
