A Pathology-Based Combined Model to Identify PAM50 Non-luminal Intrinsic Disease in Hormone Receptor-Positive HER2-Negative Breast Cancer
2019
No luminal; Subtipus intrínsec; Càncer de mama No luminal; Subtipo intrínseco; Cáncer de mama Non-luminal; Intrinsic subtype, Breast cancer Background: In hormone receptor-positive (HR+)/HER2-negative breast cancer, the HER2-enriched and Basal-like intrinsic subtypes are associated with poor outcome, low response to anti-estrogen therapy and high response to chemotherapy. To date, no validated biomarker exists to identify both molecular entities other than gene expression. Methods: PAM50 subtyping and immunohistochemical data were obtained from 8 independent studies of 1,416 HR+/HER2-negative early breast tumors. A non-luminal disease score (NOLUS) from 0 to 100, based on percentage of estr…
Real‐world evidence of tisagenlecleucel for the treatment of relapsed or refractory large B‐cell lymphoma
2021
Abstract Tisagenlecleucel (tisa‐cel) is a second‐generation autologous CD19‐targeted chimeric antigen receptor (CAR) T‐cell therapy approved for relapsed/refractory (R/R) large B‐cell lymphoma (LBCL). The approval was based on the results of phase II JULIET trial, with a best overall response rate (ORR) and complete response (CR) rate in infused patients of 52% and 40%, respectively. We report outcomes with tisa‐cel in the standard‐of‐care (SOC) setting for R/R LBCL. Data from all patients with R/R LBCL who underwent leukapheresis from December 2018 until June 2020 with the intent to receive SOC tisa‐cel were retrospectively collected at 10 Spanish institutions. Toxicities were graded accor…
Prevention of Hereditary Angioedema Attacks with a Subcutaneous C1 Inhibitor
2017
Prevenció; Atac d'angioedema; Inhibidor C1 Prevención; Ataque de angioedema; Inhibidor C1 Prevention; Angioedema attack; C1 inhibitor BACKGROUND: Hereditary angioedema is a disabling, potentially fatal condition caused by deficiency (type I) or dysfunction (type II) of the C1 inhibitor protein. In a phase 2 trial, the use of CSL830, a nanofiltered C1 inhibitor preparation that is suitable for subcutaneous injection, resulted in functional levels of C1 inhibitor activity that would be expected to provide effective prophylaxis of attacks. METHODS: We conducted an international, prospective, multicenter, randomized, double-blind, placebo-controlled, dose-ranging, phase 3 trial to evaluate the …
Oxamato/Oxamidato-Based Multifunctional Porous Coordination Polymers
2017
El principal objetivo de esta presente Tesis concierne el diseño y la síntesis de materiales multifuncionales, una línea de investigación de creciente interés dentro del campo de la Química de Materiales. Para llevar a cabo dicho objetivo, hemos aprovechado los avances que ha experimentado la química metalosupramolecular en los últimos años. Concretamente pretendemos hacer uso de los métodos de auto-ensamblaje programado basado en las diferentes preferencias que muestran los iones metálicos en sus entornos de coordinación y en la funcionalización de ligandos orgánicos. Para ello, hemos sintetizado ligandos derivados de grupos oxamato y oxamidato, que actuarán como moléculas de partida para …
The potential of serum neurofilament as biomarker for multiple sclerosis
2021
Abstract Multiple sclerosis is a highly heterogeneous disease, and the detection of neuroaxonal damage as well as its quantification is a critical step for patients. Blood-based serum neurofilament light chain (sNfL) is currently under close investigation as an easily accessible biomarker of prognosis and treatment response in patients with multiple sclerosis. There is abundant evidence that sNfL levels reflect ongoing inflammatory-driven neuroaxonal damage (e.g. relapses or MRI disease activity) and that sNfL levels predict disease activity over the next few years. In contrast, the association of sNfL with long-term clinical outcomes or its ability to reflect slow, diffuse neurodegenerativ…
Differentiating Multiple Sclerosis From AQP4-Neuromyelitis Optica Spectrum Disorder and MOG-Antibody Disease With Imaging.
2023
Background and ObjectivesRelapsing-remitting multiple sclerosis (RRMS), aquaporin-4 antibody–positive neuromyelitis optica spectrum disorder (AQP4-NMOSD), and myelin oligodendrocyte glycoprotein antibody–associated disease (MOGAD) may have overlapping clinical features. There is an unmet need for imaging markers that differentiate between them when serologic testing is unavailable or ambiguous. We assessed whether imaging characteristics typical of MS discriminate RRMS from AQP4-NMOSD and MOGAD, alone and in combination.MethodsAdult, nonacute patients with RRMS, APQ4-NMOSD, and MOGAD and healthy controls were prospectively recruited at the National Hospital for Neurology and Neurosurgery (L…
On the design of optimally inserted transmembrane helices
2017
La célula es la unidad básica estructural y funcional de la vida y todas las células están rodeadas y delimitadas por sus membranas biológicas. Las membranas juegan un papel crucial en la existencia de las células delimitándolas y conectándolas con su entorno. Las membranas biológicas están formadas principalmente por lípidos y proteínas. Mientras que los lípidos forman una bicapa que impide la difusión libre de la mayoría de moléculas e iones, las proteínas controlan el tráfico molecular y el flujo de información a través de la membrana. A estas proteínas insertadas en la membrana biológica se les denomina proteínas de membrana, caracterizadas por la presencia de regiones adaptadas para in…
Biochemical and molecular basis involved in the synthesis of melatonin and other derivatives of aromatic amino acids in Saccharomyces cerevisiae
2021
Recientemente, el metabolismo de los aminoácidos aromáticos en levaduras se ha relacionado con la síntesis de moléculas bioactivas (melatonina, serotonina, tirosol, hidroxitirosol, etc...) que podrían ser relevantes desde diferentes aspectos relacionados tanto con la regulación de las levaduras como con la salud humana. Las actividades de estos compuestos como potenteantioxidante y otros aspectos beneficiosos para la salud del consumidor hacen que sea realmente interesante estudiar su síntesis. Sin embargo, se conoce poca información sobre la síntesis de estas moléculas bioactivas por la levadura porque es un tema de estudio muy reciente. Por tanto, la hipótesis de trabajo de la presente te…
