Linkers for bioconjugation
Cancer is a heterogeneous disease that represents one of the principal causes of mortality in developed countries. Due to the social and economic implications of this pathology, tremendous efforts have been making over the ...
Linking cell dynamics with coexpression networks to characterize key events in chronic virus infection
The host immune response against infection requires the coordinated action of many diverse cell subsets that dynamically adapt to a pathogen threat. Due to the complexity of such a response, most immunological studies have ...
Linking ecology and Environmental chemistry: pelagic seabirds as indicators of marine contamination = Entre la ecología y la química ambiental: Las aves pelágicas como indicadores de la contaminación marina
Exposure to contaminants, such as Persistent Organic Pollutants (POPs), is currently considered a serious anthropogenic threat to marine predators and their food webs. Exposure to contaminants by marine wildlife is mainly ...
Linking hydrodynamic and biological processes in a shallow and micro tidal estuary : the case of Fangar bay (Ebro delta)
This thesis analyses the relationships between hydrodynamics (and their forcings) and biological variables in Fangar Bay based on in situ observations, numerical models and satellite data. Fangar Bay is a relatively small, ...
Linking institutions, entrepreneurship, and economic development: An international study
Hi ha un consens que considera a l'emprenedoria un element important que explica el procés de desenvolupament econòmic dels països. Entre altres raons, els acadèmics i els creadors de política s'han interessat en els factors ...
Linking movement ecology with ecosystem services in Pyrenean scavenger populations. An innovative approach for the avian scavenger conservation
Investigacions recents han demostrat com el consum de carronya representa un procés fonamental en el funcionament dels ecosistemes, jugant aquest un paper clau en l'ecologia de la xarxa tròfica, ecologia de poblacions i ...
Linking river sediment physical properties to biofilm biomass and activity
River sediments are composed by a variety of grain sizes which determine their permeability and biogeochemistry. The aim of this thesis was to test whether differences in river sediment physical characteristics generate ...
Linking Well-being, Nature and Tourism: A participatory approach
Aquesta tesi doctoral aprofundeix en la relació entre el benestar, la natura i el turisme des d'una perspectiva teòrica i metodològica. L’objectiu principal és entendre i demostrar la important contribució de la natura ...
Links between chromatin structure and regulation of alternative pre-mRNA splicing in mammalian cells
Intron removal is a necessary step for expression of most genes in higher eukaryotes, and alternative splice selection is a highly regulated mechanism that endows a single gene with the possibility to codify for multiple ...
Links Between Dimethylated Sulfur and Phytoplankton Photophysiology in the Surface Ocean Geographical Paterns and Short-Term Variability = Relación entre el Dimetilsulfuro y la Fotofsiología del Fitoplancton en la Superfcie del Océano. Patrones Geográfcos y Variabilidad a Corto Plazo
Dimethylsulfide (DMS) and its algal metabolite precursor, dimethylsulfoproprionate (DMSP), are major players in the oceanic and atmospheric sulfur cycle. DMS is the most abundant volatile organic sulfur compound in the ...
The links between global climatic cycles and the diversification and migration of Arctic shorebirds = La relación entre los ciclos climáticos y la diversificación y migración de las aves limícolas árticas
In this thesis we studied how the changes in the climate determine the distribution, diversity and conservation of a very representative group of the Arctic avifauna, the shorebirds. In the first chapter we explored the ...
Liouville-Weyl derivatives, best approximations, and moduli of smoothness
En aquest treball estudiem les propietats d'aproximació i de suavitat de les derivades de Liouville-Weyl generalitzades. Els tres problemes que tractem són els següents: Primer, obtenim fites superiors i inferiors per a ...
Lipid droplet biogenesis: a novel process of self-digestion as a strategy of survival to stress
Las gotas lipídicas (lipid droplets, LD) son orgánulos presentes en la mayor parte de las células eucarióticas. Están compuestas por un núcleo hidrofóbico de triacilglicéridos y ésteres de colesterol, rodeado por una ...
Lipid droplet regulation by the differentially spliced proteins Osw5L and Osw5S
Epithelial tissues undergo extensive remodeling during embryonic development. Recent studies have revealed that, in a number of developmental processes, epithelial remodeling is associated with pulsations of individual ...
Lipid raft association and subcellular localization of UNC5 Netrin-1 receptors = Associació als lípids raft i localització subcel·lular de la familia de receptors de la Netrina-1 UNC5
During brain development, UNC5 receptors play a key role in controlling axonal extension through their sensing of the guidance molecule Netrin-1. The correct positioning of receptors into specific cholesterol-enriched ...
Lipidomics by 1H-NMR of non-LDL atherogenic lipoproteins in patients with dyslipidemia. Impact on vascular and metabolic complications
Les lipoproteïnes riques en triglicèrids (LRT) representen un important factor patogènic en el context dels trasntorns lipídics. L'augment de LRT s'associa a un major risc cardiovascular degut, en part, a la seva capacitat ...
Lipidomics studies of recombinant Pichia pastoris for improved recombinant protein secretion through cell engineering
L’ús cada cop més extensiu de plataformes “òmiques” per a l’estudi de llevats ha generat grans quantitats d’informació relativa a la fisiologia cel·lular sota diferents condicions de cultiu, la qual pot ser utilitzada per ...
The lipin protein family in human adipocytes: lipid metabolism and obesity
Les lipins són una família conservada evolutivament de fosfatases de fosfatidat (PAP1) dependents de Mg2+, que generen diacilglicerol per a la síntesi de fosfolípids i triacilglicerol. En mamífers, la família consta de ...
Lipodistròfia en pacients infectats pel vih tractats amb fàrmacs antiretrovirals: determinants genètics i moleculars.
La lipodistròfia és un canvi en la distribució del greix corporal. És un efecte advers freqüent en pacients amb infecció pel VIH i s’ha relacionat amb els fàrmacs antiretrovirals, el propi VIH i una susceptibilitat genètica. ...
Lipopolysaccharide (LPS) core biosynthesis in "Proteus mirabilis" / Estudio de la biosíntesis del núcleo de lipopolisacarido (LPS) en "Proteus mirabilis"
Urinary tract infection (UTIs) is an extremely common disease. Proteus mirabilis is a common cause of UTI in individuals with functional or structural abnormalities or with long-term catheterization, it forms bladder and ...
