Influence of Ecklonia maxima Extracts on Growth, Yield, and Postharvest Quality of Hydroponic Leaf Lettuce
2021
Ecklonia maxima is a brown algae seaweed largely harvested over the last years and used to produce alginate, animal feed, fertilizers, and plant biostimulants. Their extracts are commercially available in various forms and have been applied to many crops for their growth-promoting effects which may vary according to the treated species and doses applied. The aim of the study was to characterize the effect of adding an Ecklonia maxima commercial extract (Basfoliar Kelp
Animal rennets as sources of dairy lactic acid bacteria
2014
ABSTRACT The microbial composition of artisan and industrial animal rennet pastes was studied by using both culture-dependent and -independent approaches. Pyrosequencing targeting the 16S rRNA gene allowed to identify 361 operational taxonomic units (OTUs) to the genus/species level. Among lactic acid bacteria (LAB), Streptococcus thermophilus and some lactobacilli, mainly Lactobacillus crispatus and Lactobacillus reuteri , were the most abundant species, with differences among the samples. Twelve groups of microorganisms were targeted by viable plate counts revealing a dominance of mesophilic cocci. All rennets were able to acidify ultrahigh-temperature-processed (UHT) milk as shown by pH …
The high-performance technology CRISPR/Cas9 improves knowledge and management of acute myeloid leukemia
2021
Knowledge on acute myeloid leukemia pathogenesis and treatment has progressed recently, but not enough to provide ideal management. Improving the prognosis of acute myeloid leukemia patients depends on advances in molecular biology for the detection of new therapeutic targets and the production of effective drugs. The CRISPR/Cas9 technology allows gene insertions and deletions and it is the first step in investigating the function of their encoded proteins. Thus, new experimental models have been developed and progress has been made in understanding protein metabolism, antitumor activity, leukemic cell maintenance, differentiation, growth, apoptosis, and self-renewal, the combined pathogene…
Murine liver organoids as a genetically flexible system to study liver cancer in vivo and in vitro.
2019
The rising incidence of cholangiocarcinoma (CCA) coupled with a low 5-year survival rate that remains below 10% delineates the urgent need for more effective treatment strategies. Although several recent studies provided detailed information on the genetic landscape of this fatal malignancy, versatile model systems to functionally dissect the immediate clinical relevance of the identified genetic alterations are still missing. To enhance our understanding of CCA pathophysiology and facilitate rapid functional annotation of putative CCA driver and tumor maintenance genes, we developed a tractable murine CCA model by combining the cyclization recombination (Cre)-lox system, RNA interference, …
Mecanismos de resistencia a piretroides en ácaros depredadores
2023
Los piretroides constituyen un grupo de plaguicidas catalogados como moduladores del canal de sodio (Grupo 3), según el comité de acción contra la resistencia a los insecticidas (IRAC). Estos plaguicidas son análogos sintéticos de las piretrinas, compuestos naturales con actividad insecticida que se encuentran en las flores de las plantas del género Chrysanthemum, popularmente conocidas como crisantemos. Actualmente, existen numerosos productos plaguicidas que contienen en su formulación piretroides, siendo ampliamente utilizados en el control de plagas en diferentes contextos como la agricultura, la ganadería, la apicultura e incluso a nivel doméstico, erigiéndose como uno de los grupos de…
El género Ulota Mohr en la Península Ibérica y una nueva visión del Complejo de U crispa (Hedw.) Brid. (Orthotrichaceae, Musci)
2015
La presente tesis doctoral tiene como objetivo general tratar de avanzar de una manera significativa en la taxonomía del género Ulota, sentando las bases para el estudio moderno de su diversidad. Para conseguirlo, primero se ha tratado de obtener una perspectiva general del género,centrada en el hemisferio norte aunque no restringida al mismo, mediante el estudio de más de 1.500 especímenes procedentes de numerosos herbarios (ALA, BCB, BM, BP, DUKE, FCO, FH, G, H, HIRO, LISU, MA, MAUAM, MHA, MO, MUB, NICH, NYBG, S, TU VIT, y herbarios personales de P. Boudier y D. Callaghan), así como de recolecciones realizadas ex profeso en diferentes partes del mundo por el equipo de trabajo (Turquía, Pe…
Cooperation between Different CRISPR-Cas Types Enables Adaptation in an RNA-Targeting System
2021
CRISPR-Cas systems are immune systems that protect bacteria and archaea against their viruses, bacteriophages. Immunity is achieved through the acquisition of short DNA fragments from the viral invader’s genome.
Investigating REPAIRv2 as a Tool to Edit CFTR mRNA with Premature Stop Codons
2020
Cystic fibrosis (CF) is caused by mutations in the gene encoding the transmembrane conductance regulator (CFTR) protein. Some CF patients are compound heterozygous or homozygous for nonsense mutations in the CFTR gene. This implies the presence in the transcript of premature termination codons (PTCs) responsible for a truncated CFTR protein and a more severe form of the disease. Aminoglycoside and PTC124 derivatives have been used for the read-through of PTCs to restore the full-length CFTR protein. However, in a precision medicine framework, the CRISPR/dCas13b-based molecular tool &ldquo
Da Crisp-Cas9 ecco il super pomodoro
2018
Una collaborazione internazionale ha usato la nuova tecnica di editing genomico per produrre una varietà di pomodoro molto ricca di licopene, una sostanza antiossidante preziosa per la salute. Il risultato è stato ottenuto in una sola generazione a partire dalla specie selvatica sudamericana Solanum pimpinellifolium, da cui sono derivate, dopo secoli di ibridazioni, le varietà di pomodoro che consumiamo oggi.
