Proton-irradiated breast cells: molecular points of view

2019

Abstract Breast cancer (BC) is the most common cancer in women, highly heterogeneous at both the clinical and molecular level. Radiation therapy (RT) represents an efficient modality to treat localized tumor in BC care, although the choice of a unique treatment plan for all BC patients, including RT, may not be the best option. Technological advances in RT are evolving with the use of charged particle beams (i.e. protons) which, due to a more localized delivery of the radiation dose, reduce the dose administered to the heart compared with conventional RT. However, few data regarding proton-induced molecular changes are currently available. The aim of this study was to investigate and descri…

Taxonomical and Functional Assessment of the Endometrial Microbiota in A Context of Recurrent Reproductive Failure: A Case Report

2019

Investigation of the microbial community in the female reproductive tract has revealed that the replacement of a community dominated by Lactobacillus with pathogenic bacteria may be associated with implantation failure or early spontaneous abortion in patients undergoing assisted reproductive technology (ART) treatment. Herein we describe taxonomically and functionally the endometrial microbiome of an infertile patient with repeated reproductive failures (involving an ectopic pregnancy and two clinical miscarriages). The microbiological follow-up is presented over 18-month in which the microbiota was evaluated in six endometrial fluid samples. The microbial profile of 16S rRNA gene sequenci…

Dinámica de la microbiota en niños, adolescentes y adultos

2022

La microbiota intestinal se implanta a lo largo del desarrollo del individuo y su composición y funciones difieren según la edad. Conocer los cambios que se producen en la microbiota intestinal a lo largo de la vida puede ayudar al diagnóstico, tratamiento y prevención de enfermedades relacionadas con alteraciones metabólicas e inmunitarias. Con este trabajo pretendemos contribuir a la comprensión del proceso de desarrollo de la microbiota intestinal, centrándonos en dos períodos que han recibido poca atención: los primeros años y la adolescencia. Hemos determinado la composición y la función de la microbiota a través de enfoques metagenómicos de genoma completo y basados ​​en ARN ribosómic…

Study of the interactions between Broad bean wilt virus 1 and its host plants

Broad bean wilt virus 1 (BBWV-1) is the type member of the Fabavirus genus, in the Secoviridae family. BBWV-1 is worldwide distributed and infects important horticultural and ornamental crops causing considerable economic losses. However, information about the biological and molecular characteristics of BBWV-1 isolates is scarce. BBWV-1 is composed of two molecules of positive single-stranded RNA (ssRNA+) that are separately encapsidated in virions of icosahedral morphology. Each ssRNA+ encodes polyproteins which are processed by proteolytic cleavage into functional peptides. RNA1 (~ 5.8 kb) encodes for one polyprotein that renders proteins involved in viral replication: a protease cofactor…
