Treball Final de Grau en Medicina. Codi: MD1158. Curs acadèmic: 2020/2021 Antecedentes y Objetivos La pandemia por COVID-19 ha supuesto un gran impacto social, económico, psicológico y sanitario. Conocer los determinantes de salud nos ayuda a mejorar las estrategias de detección y control del virus, con el que podemos garantizar la salud pública. El objetivo de este estudio ecológico es describir la distribución del Sars-CoV2 en función de la edad, sexo, y tamaño municipal, en los departamentos de Castellón y la Plana, durante la segunda y tercera onda epidémicas. Métodos Se ha utilizado la base de datos sistema de Vigilancia Epidemiológica, Enfermedades de declaración obligatoria: COVID-19, de donde hemos sustraído los casos positivos desde el 10/05/2020 hasta el 6/03/2021 de los departamentos de Castellón y la Plana. Los indicadores epidemiológicos que se han utilizado han sido el número de casos, la Incidencia Acumulada (IA) semanal y total y la tasa de incidencia por persona/año. Todos los datos han sido segmentados y comparados por departamento y onda. Resultados La tercera onda ha tenido una tasa de incidencia 4.5 y 6.9 veces superior en el departamento de Castellón y en la Plana, respectivamente. Entre departamentos, la incidencia ha sido mayor en el departamento de Castellón en la segunda onda, y en el departamento de la Plana en la tercera. Los positivos se han concentrado en el grupo de edad de 40-49 años, con ligero predominio en el sexo femenino, aunque sin diferencias significativas entre ambos sexos. En cuanto al tamaño municipal, no existe un claro patrón de relación lineal entre las IA y el tamaño poblacional. Conclusiones La pandemia por Sars-CoV-2 ha afectado de forma diferente entre los determinantes epidemiológicos: En tiempo, la tercera onda ha tenido mayor impacto que la segunda; en persona, los positivos se han focalizado en el grupo de 40-49 sin diferencias significativas entre sexos; y en espacio, las incidencias han predominado en el departamento de Castellón en la segunda onda y en la Plana, en la tercera, sin un claro patrón lineal entre el tamaño poblacional y la Incidencia Acumulada. Background The COVID-19 pandemic has had a great social, economic, psychological and health impact. Knowledge of health determinants helps us to improve the detection and develop control strategies of the virus, with which we can guarantee public health. The objective of this ecological study is to describe the distribution of Sars-CoV-2 according to age, sex, and municipal size, in the departments of Castellón and La Plana, during the second and third pandemic waves. Methods We have used the Epidemiological Surveillance System, Mandatory Notifiable Diseases: COVID-19 database, from which we have subtracted positive cases 05/10/2020 to 03/06/2021, from the departments of Castellón and La Plana. The epidemiological indicators what we have used are the number of cases, the weekly and total Cumulative Incidence (CI) and the incidence rate per person / year. We have segmented and compared all data by department and wave. Results The third wave has had an impact 4.5 and 7 times higher in the department of Castellón and in La Plana, respectively. Between departments, the CI has been higher in the department of Castellón in the second wave, and in the department of La Plana in the third. The positives have been concentrated in the age group of 40-49 years, with a slight predominance in the female sex, although without significant differences between both sexes. As to municipal size, there is no clear linear relationship pattern between AI and population size. Conclusions The covid pandemic has affected differently according to epidemiological determinants person, time, and space. In time, the third wave has had a greater impact than the second; in person, the positives have focused on the 40-49 group without significant differences between the sexes; and in space, the incidences have predominated in the department of Castellón in the second wave and in the Plana, in the third wave, without a clear linear pattern between the population size and the Accumulated Incidence.

- Abstract
Despite the abundant literature on the adverse effects of Bisphenol A (BPA) as endocrine disruptor, its toxicity mechanisms are still poorly understood. We present here a study of its effects on the zebrafish eleutheroembryo transcriptome at concentrations ranging from 0.1 to 4 mg L−1, this latter representing the lowest observed effect concentration (LOEC) found in our study at three different macroscopical endpoints (survival, hatching and swim bladder inflation). Multivariate data analysis methods identified both monotonic and bi-phasic patterns of dose-dependent responses. Functional analyses of genes affected by BPA exposure suggest an interaction of BPA with different signaling pathways, being the estrogenic and retinoid receptors two likely targets. In addition, we identified an apparently unrelated inhibitory effect on, among others, visual function genes. We interpret our data as the result of a sum of underlying, independent molecular mechanisms occurring simultaneously at the exposed animals, well below the macroscopic LOEC, but related to at least some of the observed morphological alterations, particularly in eye size and yolk sac resorption. Our data supports the idea that the physiological effects of BPA cannot be only explained by its rather weak interaction with the estrogen receptor, and that multivariate analyses are required to analyze the effects of toxicants like BPA, which interact with different cellular targets producing complex phenotypes.

Objetivo: Describir los resultados obtenidos en el uso de nab-paclitaxel y gemcitabina en el tratamiento de pacientes con adenocarcinoma de páncreas metastático. Material y métodos: Estudio observacional retrospectivo. Se seleccionaron pacientes en tratamiento con nab-paclitaxel asociado a gemcitabina entre enero 2013 y enero 2014. Se recogieron datos demográficos y clínicos. Resultados: Se incluyeron 15 pacientes (edad media: 59,4 ± 10,3 años). Todos ellos recibieron la combinación de nab-paclitaxel y gemcitabina en primera línea para la enfermedad metastásica. Nueve recibieron tratamiento adyuvante antes de que la enfermedad fuera metastásica, siendo la media de líneas de tratamiento previamente al uso de la combinación de 1,1. La mediana de supervivencia libre de progresión fue de 5,6 meses (IC 95%: 4,44 - 8,03). Sólo dos pacientes suspendieron el tratamiento por toxicidad. Conclusiones: El tratamiento con nab-paclitaxel y gemcitabina en nuestros pacientes ha resultado en una supervivencia libre de progresión similar a la de los ensayos clínicos publicados, presentando además una buena tolerancia Objective: To evaluate the results obtained with the combined use of nab-paclitaxel and gemcitabine in the treatment of patients with metastatic pancreatic adenocarcinoma. Materials and methods: Retrospective observational study. Patients treated with nab-paclitaxel and gemcitabine between January of 2013 and January of 2014 were selected. Demographical and clinical data were gathered. Results: 15 patients (mean age 59,4 ± 10,3 years) were included. All patients received the combination of nab-paclitaxel and gemcitabine in first-line metastatic disease. Nine received adjuvant treatment before the disease was metastatic. The median progression-free survival rate with combined nab-paclitaxel and gemcitabine was 5,6 months (95% CI: 4,44 - 8,03). In two patients the treatment was stopped due to toxicity. Conclusions: The treatment with nab-paclitaxel and gemcitabine in our patients resulted in progression-free survival rates similar to those published in clinical trials with good treatment tolerability.

[cat] L’aplicació de tecnologies transcriptòmiques i metabolòmiques en estudis no dirigits té com a principal objectiu la caracterització global (funcional i estructural) dels transcrits de mRNA i dels metabòlits, respectivament, que conformen els sistemes biològics. En el camp mediambiental, aquestes dues aproximacions òmiques permeten avaluar i comparar els nivells d’aquestes molècules en els organismes vius en resposta a diferents estímuls o variacions en les condicions ambientals. D’aquesta manera, ambdues ciències proporcionen coneixement de les interaccions dels sistemes biològics amb el seu entorn a nivell molecular. En els estudis òmics no dirigits són imprescindibles les tècniques analítiques d’alt rendiment com la seqüenciació de RNA (RNA-Seq) i les tècniques de separació acoblades a l’espectrometria de masses, com per exemple la cromatografia de líquids i l’electroforesi capil·lar acoblades a l’espectrometria de masses (LC-MS i CE-MS, respectivament). Ara bé, els grans conjunts de dades generats en aquests estudis són complexos i fan necessari el desenvolupament i l’aplicació de mètodes estadístics i quimiomètrics multivariants d’anàlisi de dades, els quals permetin extreure la informació biològica rellevant i facilitar-ne la seva interpretació. Aquesta Tesi s’ha centrat especialment en el desenvolupament de mètodes analítics i quimiomètrics que puguin ser útils en aquests tipus estudis i en la seva aplicació en diversos casos d’interès ambiental i toxicològic on es pren el peix zebra com a organisme model. D’una banda, s’ha treballat en el desenvolupament i optimització de mètodes analítics de LC-MS i CE-MS i de tractament de dades multivariants per a estudis de metabolòmica no dirigida. S’ha avaluat la influència de diferents factors experimentals en la separació de metabòlits mitjançant la cromatografia de líquids d'interacció hidrofílica (HILIC) (per exemple, la fase estacionària, el pH, la força iònica i el modificador orgànic). També, s’han optimitzat les condicions experimentals per a l’anàlisi metabolòmica no dirigida mitjançant la tècnica de CE-MS. D’altra banda, s’han presentat diferents estratègies de tractament de dades metabolòmiques no dirigides basades en la resolució multivariant de corbes per mínims quadrats alternats (MCR-ALS), les quals permeten la detecció i la identificació dels metabòlits de les dades de LC-MS i CE-MS. Finalment, s’ha aplicat la compressió de les dades de cerca de regions d’interès (ROI) i la resolució per MCR-ALS (mètode ROIMCR) per a l’estudi simultani o fusió de conjunts de dades que provenen de diferents plataformes de MS. La idoneïtat de totes aquestes metodologies analítiques i quimiomètriques s’ha demostrat en estudis comparatius dels perfils metabòlics de mostres de llevat (Saccharomyces cerevisiae) en diferents condicions de creixement estressants. Un segon aspecte d’aquesta Tesi ha estat l’aplicació de les metodologies prèviament proposades en la investigació dels possibles efectes de diferents compostos disruptors endocrins, com ara el bisfenol A (BPA), el sulfonat de perfluorooctà (PFOS) i el tributilestany (TBT), en embrions de peix zebra (Danio rerio). En concret, s’ha detectat que els tres contaminants produeixen importants alteracions en el metabolisme dels embrions, produint efectes tòxics, estrès oxidatiu i alteracions en la proliferació cel·lular, a més d’efectes específics en vies de senyalització. Addicionalment, s’han postulat noves hipòtesis sobre els efectes toxicològics i morfològics adversos d’aquests compostos químics. En el cas del BPA s’ha realitzat, a més, un estudi transcriptòmic no dirigit de seqüenciació de RNA (RNA-Seq), que ha permès obtenir informació addicional a l’extreta a nivell metabolòmic, la qual cosa permet una comprensió més global i conjunta del mecanisme d’acció del BPA en el metabolisme dels embrions., [eng] The application of transcriptomic and metabolomic technologies in non-targeted studies is primarily based on the global (functional and structural) characterization of mRNA transcripts and metabolites, respectively, in biological systems. In the environmental field, these two omic approaches aim at the evaluation and comparison of the abundances of these molecules in biological organisms in response to external stimuli. In this way, both omic sciences provide knowledge about the interactions of the biological systems with their environments at the molecular level. Non-targeted transcriptomics and metabolomics have progressed due to advances in high-performance analytical techniques, such as RNA-sequencing (RNA-Seq) and separation techniques coupled with mass spectrometry (e.g., liquid chromatography-mass spectrometry, LC-MS; and capillary electrophoresis-mass spectrometry, CE- MS). However, datasets generated in these studies are large and complex. Therefore, the development and application of multivariate chemometric data analysis methods are mandatory to extract the relevant information and achieve a reliable biological interpretation. The first half of this thesis focuses on the development and optimization of LC-MS and CE-MS methodologies in combination with advanced chemometric tools for non-targeted metabolomic studies. Firstly, the influence of different experimental factors in the separation of metabolites by hydrophilic interaction liquid chromatography (HILIC), such as the type of stationary phase, the organic modifier and the pH and the ionic strength of the mobile phase, was evaluated. Also, the experimental conditions for a non-targeted metabolomic analysis using CE-MS technique were optimized. Secondly, different data treatment strategies based on the use of multivariate curve resolution by alternating least squares (MCR-ALS) for the detection and identification of the metabolites from non-targeted LC-MS and CE-MS metabolomics data were presented. Finally, the search of the regions of interest (ROI) data compression in combination with MCR-ALS resolution (so-called ROIMCR method) was applied for the simultaneous study or fusion of datasets from different MS platforms. The suitability of all these analytical and chemometric methodologies was shown in comparative studies of the metabolic profiles of yeast (Saccharomyces cerevisiae) samples under different growth stressors. The second half of this thesis deals with the application of the previously proposed methodologies in the investigation of the effects of different endocrine disrupting compounds (e.g., bisphenol A, BPA; perfluorooctane sulfonate, PFOS; and tributyltin, TBT) on zebrafish (Danio rerio) embryos. These three pollutants produced important alterations on embryo metabolism, causing toxic effects, oxidative stress and alterations in cell proliferation, as well as specific effects in signaling pathways. Additionally, new hypotheses were postulated on the adverse toxicological and morphological effects of these chemical compounds. In order to extract more information about BPA effects on the exposed embryos, a non-targeted transcriptomic approach based on RNA-Seq was performed. Overall, the combination of the knowledge coming from both omic levels allowed a global understanding of the mechanism of action of BPA on embryo metabolism.

- Abstract
Bisphenol A (BPA), perfluorooctane sulfonate (PFOS), and tributyltin (TBT) are emerging endocrine disruptors (EDCs) with still poorly defined mechanisms of toxicity and metabolic effects in aquatic organisms. We used an untargeted liquid chromatography-high resolution mass spectrometry (LC-HRMS) metabolomic approach to study the effects of sub-lethal doses of these three EDCs on the metabolic profiles of zebrafish embryos exposed from 48 to 120 hpf (hours post fertilization). Advanced chemometric data analysis methods were used to reveal effects on the subjacent regulatory pathways. EDC treatments induced changes in concentrations of about 50 metabolites for TBT and BPA, and of 25 metabolites for PFOS. The analysis of the corresponding metabolic changes suggested the presence of similar underlying zebrafish responses to BPA, TBT and PFOS affecting the metabolism of glycerophospholipids, amino acids, purines and 2-oxocarboxylic acids. We related the changes in glycerophospholipid metabolism to alterations in absorption of the yolk sack, the main source of nutrients (including lipids) for the developing embryo, linking the molecular markers with adverse phenotypic effects. We propose a general mode of action for all three chemical compounds, probably related to their already described interaction with the PPAR/RXR complex, combined with specific effects on different signaling pathways resulting in particular alterations in the zebrafish embryos metabolism. © 2018 Elsevier B.V.

La poliposis adenomatosa familiar (PAF) es la forma más frecuente y conocida de poliposis. Se trata de una enfermedad hereditaria autosómica dominante caracterizada por el desarrollo de múltiples pólipos adenomatosos, principalmente en el colon y recto. La prevalencia de esta enfermedad es de aproximadamente 1 de cada 10.000-20.000 individuos. La aparición de los pólipos suele iniciarse a una edad temprana, con un riesgo de casi el 100% de desarrollo de cáncer colorrectal (CCR) si el paciente no recibe tratamiento de forma precoz. Las lesiones suelen desarrollarse en la segunda y la tercera década de la vida: el 15% a los 10 años de edad, el 50% de los pacientes sobre los 15 años y un 95% a los 35 años. Este artículo tiene como objetivo presentar la evolución clínica y nutricional de una paciente de 54 años de edad diagnosticada de PAF que precisa nutrición parenteral complementaria (NPC) domiciliaria, así como evaluar los resultados clínicos de esta paciente. A través de la revisión de la historia clínica, se estudió la evolución de los datos antropométricos (peso y talla), así como los parámetros analíticos para su valoración. Paciente de 54 años de edad diagnosticada de PAF que acudió a nuestro hospital tras trasladarse temporalmente de ciudad para recibir soporte nutricional. El artículo describe la composición de la NPC recibida durante los 90 días de seguimiento. La NPC en este tipo de pacientes es importante, ya que presentan una insuficiencia del tracto gastrointestinal irreversible que les impide la absorción de nutrientes apropiados para mantener una adecuada calidad de vida. Familial adenomatous polyposis (FAP) is the most common known form of polyposis. It is an autosomal dominant inherited disease characterized by the development of multiple adenomatous polyps mainly in the colon and rectum. The prevalence of this disease is approximately about 1 in every 10,000-20,000 people. The appearance of the polyps usually starts at an early age with a 100% risk of developing colorectal cancer (CRC) if the patient does not receive early treatment. These lesions usually manifest during the second and third decades of life: 15% at the age of 10, 50% around 15 years of age and 95% at the age of 35. This article aims to present the clinical and nutritional evolution of a 54 years old patient diagnosed with FAP who requires complementary home parenteral nutrition (CPN), and the evaluation of these patient clinical outcomes. The evolution of anthropometric data (weight and height) and the results of laboratory parameters were followed and studied by review of medical records. The patient diagnosed with FAP was referred to our hospital after a temporary city transfer to receive nutritional support. This article describes the composition of the CPN received during the 90 days of follow up. CPN in these patients is important because of the irreversible gastrointestinal tract failure that prevents them from absorbing sufficient nutrients to maintain an adequate quality of life.

Introducción: La enfermedad de Hirschsprung (EH) o megacolon agangliónico es un trastorno congénito que se caracteriza por la ausencia de células ganglionares intramurales de los plexos mioentéricos submucosos (de Auerbach y Meissner, respectivamente) en tramos distales del intestino, debido al fracaso de la migración de los precursores de estas células desde la cresta neural durante el desarrollo embrionario y asociada a otras anomalías en el 18% restante de los casos, en ocasiones formando parte de síndromes polimalformativos específicos. Objetivo: Este artículo tiene como objetivo presentar la evolución clínica y nutricional de un paciente pediátrico de 14 meses diagnosticado de EH al nacer asociado a MWS, así como evaluar los resultados clínicos de este paciente. Métodos: A través de la revisión de la historia clínica, se estudió la evolución de los datos antropométricos (peso y talla) así como los parámetros analíticos para su valoración. Adicionalmente, se evaluaron las complicaciones asociadas al soporte nutricional y la estrategia terapéutica en el contexto multidisciplinar. Resultados: Paciente de 14 meses, sexo masculino, hijo de padres sanos no consanguíneos inmigrantes de Colombia acude al servicio de urgencias de nuestro hospital por presentar distensión abdominal y vómitos con ausencia de deposiciones espontáneas. Descripción de la composición de la nutrición parenteral recibida durante los 28 días que duró su ingreso hospitalario. Conclusión: La asociación de la enfermedad de Hirschsprung y el síndrome de Mowat-Wilson puede conducir a la necesidad de nutrición parenteral de manera prolongada y presentar con mayor frecuencia desvío del estoma produciéndose un mayor número de complicaciones postoperatorias en estos pacientes, tal y como es el caso de nuestro paciente. Introduction: Hirschsprung's disease (HD) or aganglionic megacolon is a congenital disorder characterized by the absence of ganglion intramural cells of the submucosal myenteric plexus (namely Auerbach and Meissner, respectively) in distal sections of the intestine. This is due to a failure in the migration of the precursors of these cells from the neural chalk during the embryonic development and also due to other abnormalities associated (18 % of cases), in some cases involving specific polymalformation syndromes. Objectives: The aim of the work is to present the clinical and nutritional evolution of a 14 months aged pediatric patient who was diagnosed with HD since was born associated with Mowat- Wilson syndrome (MWS). In addition, it is also targeted to evaluate the clinical results from this patient. Methods: Reviewing the medical history of the patient, the evolution of the anthropometric data (weight and height) as well as the analytical parameters for further studies were carried out. In addition, the upcoming issues associated with nutritional support and therapeutic strategies in the multidisciplinary context were evaluated. Results: A male, 14 months aged patient, son of not consanguineous healthy immigrants parents from Colombia went to the emergency department of our hospital suffering abdominal distension and vomiting with no spontaneous bowels. A detailed description of the composition of parenteral nutrition administered within the period of 28 days of hospital admission. Conclusion: As observed in this patient, the association of HD and MWS can lead to the need of prolonged parenteral nutrition and frequently present diverting stoma leading to a greater number of postoperative complications in this population.

- Abstract
In this work, two knowledge integration strategies based on multivariate curve resolution alternating least squares (MCR-ALS) were used for the simultaneous analysis of data from two metabolomic platforms. The benefits and the suitability of these integration strategies were demonstrated in a comparative study of the metabolite profiles from yeast (Saccharomyces cerevisiae) samples grown in non-fermentable (acetate) and fermentable (glucose) carbon source. Untargeted metabolomics data acquired by capillary electrophoresis-mass spectrometry (CE-MS) and liquid chromatography-mass spectrometry (LC-MS) were jointly analysed. On the one hand, features obtained by independent MCR-ALS analysis of each dataset were joined to obtain a biological interpretation based on the combined metabolic network visualization. On the other hand, taking advantage of the common spectral mode, a low-level data fusion strategy was proposed merging CE-MS and LC-MS data before the MCR-ALS analysis to extract the most relevant features for further biological interpretation. Then, results obtained by the two presented methods were compared. Overall, the study highlights the ability of MCR-ALS to be used in any of both knowledge integration strategies for untargeted metabolomics. Furthermore, enhanced metabolite identification and differential carbon source response detection were achieved when considering a combination of LC-MS and CE-MS based platforms. © 2017 Elsevier B.V.

- Abstract
Metabolomics is a powerful and widely used approach that aims to screen endogenous small molecules (metabolites) of different families present in biological samples. The large variety of compounds to be determined and their wide diversity of physical and chemical properties have promoted the development of different types of hydrophilic interaction liquid chromatography (HILIC) stationary phases. However, the selection of the most suitable HILIC stationary phase is not straightforward. In this work, four different HILIC stationary phases have been compared to evaluate their potential application for the analysis of a complex mixture of metabolites, a situation similar to that found in non-targeted metabolomics studies. The obtained chromatographic data were analyzed by different chemometric methods to explore the behavior of the considered stationary phases. ANOVA-simultaneous component analysis (ASCA), principal component analysis (PCA) and partial least squares regression (PLS) were used to explore the experimental factors affecting the stationary phase performance, the main similarities and differences among chromatographic conditions used (stationary phase and pH) and the molecular descriptors most useful to understand the behavior of each stationary phase.

- Abstract
Different hydrophilic interaction liquid chromatography (HILIC) stationary phases have been evaluated using different chemometric methods with the aim of their application in metabolomics studies. Experimental factors, such as the type of HILIC stationary phase (i.e. amide, amine, zwitterionic and diol) and the mobile phase conditions (organic co-solvent, pH and ionic strength) were assessed using a full factorial experimental design. A test sample mixture of metabolites with diverse physicochemical properties (amino acids, nucleotides, nucleosides, and sugars among others) was analyzed by liquid chromatography with a diode array detector (LC-DAD) using five different HILIC columns. Application of multivariate curve resolution alternating least squares (MCR-ALS) method, allowed the full chromatographic peak resolution of all mixture constituents. This approach was particularly helpful in the case of methanol samples where the quality of the chromatographic separation (resolution) was lower in consequence of the co-solvent perturbation on the water layer formation at the surface of the stationary phase. Then, Berridge chromatographic response function (CRF), based on peak resolution, retention times and number of peaks, was used for the investigation of the best HILIC column configuration for future metabolomics studies. The best chromatographic configuration resulted in being the amide and zwitterionic HILIC stationary phases in combination with acetonitrile as organic co-solvent of the mobile phase. © 2017 The Royal Society of Chemistry.

- Abstract
Although bisphenol A (BPA) is commonly recognized as an endocrine disruptor, the metabolic consequences of its exposure are still poorly understood. In this study, we present a non-targeted LC-MS based metabolomic analysis in combination with a full-genome, high-throughput RNA sequencing (RNA-Seq) to reveal the metabolic effects and the subjacent regulatory pathways of exposing zebrafish embryos to BPA during the first 120 hours post-fertilization. We applied multivariate data analysis methods to extract biochemical information from the LC-MS and RNA-Seq complex datasets and to perform testable predictions of the phenotypic adverse effects. Metabolomic and transcriptomic data revealed a similar subset of altered pathways, despite the large difference in the number of identified biomarkers (around 50 metabolites and more than 1000 genes). These results suggest that even a moderate coverage of zebrafish metabolome may be representative of the global metabolic changes. These multi-omic responses indicate a specific metabolic disruption by BPA affecting different signaling pathways, such as retinoid and prostaglandin metabolism. The combination of transcriptomic and metabolomic data allowed a dynamic interpretation of the results that could not be drawn from either single dataset. These results illustrate the utility of -omic integrative analyses for characterizing the physiological effects of toxicants beyond the mere indication of the affected pathways. © 2017 Elsevier Ltd

In this work, an untargeted approach based on capillary electrophoresis-mass spectrometry (CE-MS) in combination with multivariate data analyses is proposed as a high-throughput general methodology for metabolomic studies. First, total ion electropherograms (TIEs) were considered for exploratory and classification purposes by means of principal component analysis (PCA) and partial least squares discriminant analysis (PLS-DA). Then, multivariate curve resolution alternating least squares (MCR-ALS) was applied to the multiple full scan MS data sets. This strategy permitted the resolution of a large number of metabolites being characterized by their electrophoretic peaks and their corresponding mass spectra. The proposed approach allowed solving additional electrophoretic issues, such as background noise contributions, low signal-to-noise ratios, asymmetric peaks and migration time shifts. The usefulness of the proposed methodology is demonstrated in a comparative study of the metabolic profiles from baker's yeast (Saccharomyces cerevisiae) samples cultured at two temperatures, 30°C and 37°C. A total number of 80 metabolites were relevant to yeast samples differentiation at the two temperatures and almost 50 of them were tentatively identified based on their accurate experimental molecular mass. The results show that changes in amino acid, nucleotide and lipid metabolic pathways participated in the acclimatization of yeast cells to grow at 37°C., The research leading to these results has received funding from the European Research Council under the European Union's Seventh Framework Programme (FP/2007-2013) / ERC Grant Agreement n. 32073. Some part of this study was also supported by a grant from the Spain’s Ministry of Education and Science (CTQ2011-27130). Also, recognition from the Catalan government (grant 2014 SGR 1106) is acknowledged. JJ acknowledges a CSIC JAE-Doc contract cofounded by the FSE.
