Comparative study of molecular processes and factors affecting endometrial function in subfertile patients with uterine disorders
2021
El endometrio humano es un tejido dinámico y complejo que solo es receptivo al embrión durante un corto periodo de tiempo. Por lo tanto, la identificación de trastornos y factores que impidan que el endometrio adquiera un fenotipo receptivo es crucial para poder prevenir fallos de implantación embrionaria y aumentar las tasas de embarazo. Los trastornos uterinos son complejos, multifactoriales y poligénicos y a menudo comprometen la fertilidad femenina, aunque se desconoce con exactitud cómo afectan a la adquisición de la receptividad endometrial. Además, estos trastornos carecen actualmente de un tratamiento efectivo, a menudo presentan comorbilidad entre ellos y su incidencia aumenta con …

Visually induced motion sickness and presence in videogames: The role of sound
2012
Visually induced motion sickness (VIMS) is a well-known phenomenon in virtual environments, simulators, and videogames. We conducted an experiment to analyze the role of sound on the severity of VIMS and the feeling of presence in videogames. Thirty-two subjects first watched a pre-recorded sequence of the game “Mirrors Edge” and then played the game actively. Game-play sound was activated for half of the participants. VIMS was measured via the Simulator Sickness Questionnaire and the Fast Motion Sickness Scale, presence was captured using the Presence Questionnaire. Results showed severe VIMS in all participants during the passive video session, whereas active-play revealed only moderate …
Oxidatively generated DNA base modifications: Relation to eustress and distress
2020
Abstract Oxidative stress at the DNA, i.e., the generation of DNA damage by endogenously produced reactive oxygen species, is of particular concern as it can give rise to mutations and thereby an increased cancer risk. On the other hand, there is accumulating evidence that oxidized DNA bases, in particular 8-oxo-7,8-dihydroguanine (8-oxoG), are actively generated in mammalian cells as epigenetic marks and are involved in transcriptional regulation. To better understand this apparent paradox, this chapter first describes the types and mechanisms of DNA damage under conditions of exogenous and endogenous oxidative stress. It then summarizes the indications that oxidatively generated DNA damag…
Attitude and knowledge of pain management among Italian nurses in hospital settings
2015
Pain is multidimensional, and, as such, the chief reason patients seek urgent healthcare services. If inadequately assessed and untreated, pain may negatively impact on the quality of life of the patient. Treating pain is an important step in regaining control over quality of life. The objective of the present study is to examine the level of knowledge and types of approach among Italian nurses who deal with pain assessment and management. The Ferrell and McCaffery's Knowledge and Attitudes Survey Regarding Pain (KASRP) was distributed to 286 nurses employed in one of the biggest specialized hospitals in Rome, Italy. The interviewed staff work at three different settings, according to the h…
The FOXP2-Driven Network in Developmental Disorders and Neurodegeneration
2017
The transcription repressor FOXP2 is a crucial player in nervous system evolution and development of humans and songbirds. In order to provide an additional insight into its functional role we compared target gene expression levels between human neuroblastoma cells (SH-SY5Y) stably overexpressing either human FOXP2 cDNA or its orthologues from the common chimpanzee, Rhesus monkey, and marmoset, respectively. Subsequent RNA-seq led to identification of 27 genes with differential regulation under the control of human FOXP2, which were previously reported to have FOXP2-driven and/or songbird song-related expression regulation. Importantly, RT-qPCR and Western blotting indicated differential re…
Psychotropic drugs and driving: prevalence and types
2013
Background Some psychotropic medications (e.g., benzodiazepines, sedative antidepressants, etc.) may impair cognitive and psychomotor functions and, therefore, endanger traffic safety (Ravera, Br J Clin Pharmacol, 72(3):505–513, 2011). They affect detection, registration, and information processing, problem solving, and decision-making processes, and they also affect emotional and social aspects. The objective of this research was to clarify three closely related issues that are significant for traffic safety: the prevalence of psychotropic drugs on driving, the most frequently used psychotropic drugs to treat depression, anxiety, insomnia, or any tranquilizers (whether it is a medical pres…
Interleukin-22 and interleukin-22-producing NKp44+ natural killer cells in subclinical gut inflammation in ankylosing spondylitis
2012
Objective The intestinal inflammation observed in patients with ankylosing spondylitis (AS) is characterized by an overexpression of interleukin-23 (IL-23). IL-23 is known to regulate IL-22 production through lamina propria NKp44+ natural killer (NK) cells, which are thought to be involved in protective mucosal mechanisms. This study was undertaken to evaluate the frequency of NKp44+ NK cells and the expression of IL-22 in the ileum of AS patients. Methods Tissue NKp44+ NK cells, NKp46+ NK cells, and IL-22–producing cells were analyzed by flow cytometry. Quantitative gene expression analysis of IL-22, IL-23, IL-17, STAT-3, and mucin 1 (MUC-1) was performed by reverse transcriptase–polymeras…
The LuxR Regulators PcoR and RfiA Co-regulate Antimicrobial Peptide and Alginate Production in Pseudomonas corrugata
2018
Cyclic lipopeptides (CLPs) are considered as some of the most important secondary metabolites in different plant-associated bacteria, thanks to their antimicrobial, cytotoxic, and surfactant properties. In this study, our aim was to investigate the role of the Quorum Sensing (QS) system, PcoI/PcoR, and the LuxR-type transcriptional regulator RfiA in CLP production in the phytopatogenic bacterium, Pseudomonas corrugata based on our previous work where we reported that the pcoR and rfiA mutants were devoid of the CLPs cormycin and corpeptin production. Due to the close genetic link between the QS system and the RfiA (rfiA is co-transcribed with pcoI), it was difficult to ascertain the specifi…
Temporal dominance of sensations
2017
International audience; Sensory evaluation is a scientific discipline used to evoke, measure, analyse and interpret responses to products perceived through the senses of sight, smell, touch, taste and hearing. It is used to reveal insights into the way in which sensory properties drive consumer acceptance and behaviour, and to design products that best deliver what the consumer wants. It is also used at a more fundamental level to provide a wider understanding of the mechanisms involved in sensory perception and consumer behaviour. Sensory perception of products alters considerably during the course of consumption/use. Special techniques are used in product development to measure these chan…
