DETERMINATION OF ABUSED SUBSTANCES IN BIOLOGICAL MATRICES FOR TOXICOLOGICAL AND FORENSIC PURPOSES
2019
During the year 2017, a research work was carried out at the Department of laboratory diagnostics - Toxicology and Biochemistry U.O.S. of ASP 6 in Palermo. The purpose of this investigation was to perform a second level analysis in order to look for abuse drugs. The sample used consisted of 73 serum tubes, which had previously tested positive for screen- ing tests. The result of the analysis of these samples revealed a false positivity in most cases. From the information gathered through the sampling reports, it appears that the age group with several drivers, who are subject to checks by the traffic police, is the one from 17 to 30 years, with 35 samples analysed (48%). It also emerged tha…
Fear of Childbirth, Self-Esteem and Birth Experiences: Pregnancy and Postpartum
2022
This dataset contains all three phases of data collection from the survey study Fear of Childbirth, Birth Experiences, Self-Esteem and Parental Burnout. The data contains answers from participants (n=125) in late pregnancy (30+ weeks in gestation) and postpartum (4-8 weeks after childbirth and 1 year after childbirth). The data is collected in 2020-2021 from four Finnish cities. Participants have completed background information (in pregnancy), fear of childbirth scale (W-DEQ, all three time points), Rosenberg self-esteem scale (all three time points), and Delivery Satisfaction scale (only 4-8 weeks postpartum). In addition, the data contains variables such as depression (BDI), satisfaction…
Internet out of control: The role of self-esteem and personality traits in pathological internet use
2017
Objective: Young people seem particularly likely to develop pathological Internet use (PIU) with the use of social networks, chat, and videos. Sensation-seeking, neuroticism, introversion, and low self-esteem are personality features frequently associated with the disease. The aim of this study was to replicate and to extend previous findings by exploring the combined effect of personality traits and self-esteem on PIU. Method: A sample of 652 male students attending vocational technical schools in Palermo (Southern Italy) was assessed using the following measures: the Zuckerman-Kuhlman Personality Questionnaire to evaluate personality traits; the Multidimensional Self-Concept Scale to asse…

In this paper the results on three simple flumes for flow measurements are discussed.
Consensus nomenclature for CD8(+) T cell phenotypes in cancer
2015
International audience; Whereas preclinical investigations and clinical studies have established that CD8+ T cells can profoundly affect cancer progression, the underlying mechanisms are still elusive. Challenging the prevalent view that the beneficial effect of CD8+ T cells in cancer is solely attributable to their cytotoxic activity, several reports have indicated that the ability of CD8+ T cells to promote tumor regression is dependent on their cytokine secretion profile and their ability to self-renew. Evidence has also shown that the tumor microenvironment can disarm CD8+ T cell immunity, leading to the emergence of dysfunctional CD8+ T cells. The existence of different types of CD8+ T…
A Process-Oriented View of Procedural Memory Can Help Better Understand Tourette’s Syndrome
2021
Tourette’s syndrome (TS) is a neurodevelopmental disorder characterized by repetitive movements and vocalizations, also known as tics. The phenomenology of tics and the underlying neurobiology of the disorder have suggested that the altered functioning of the procedural memory system might contribute to its etiology. However, contrary to the robust findings of impaired procedural memory in neurodevelopmental disorders of language, results from TS have been somewhat mixed. We review the previous studies in the field and note that they have reported normal, impaired, and even enhanced procedural performance. These mixed findings may be at least partially be explained by the diversity of the s…
Effets du bruit marin sur le changement des poissons sparidés juvéniles entre les espèces et les stades de développement
2023
International audience; Marine noise is an emerging pollutant inducing a variety of negative impacts on many animal taxa, including fish. Fish population persistence and dynamics rely on the supply of early life stages, which are often very sensitive to disturbance. Impacts of marine noise pollution (MNP) on juvenile fish have rarely been investigated in temperate regions. This is particularly true for the Mediterranean Sea, which is considered as an MNP hotspot due to intensive maritime traffic. In this study, we investigate the relationship between MNP related to boat traffic and (i) assemblage structure and (ii) the density of juvenile fishes (post-settlers at different stages) belonging…
Epigenetic regulation of sex differences in susceptibility to stress
2017
Under current diagnostics depression and stress related mood disorders have a higher occurrence in women than men. Little is known of the biological mechanisms contributing to these sex differences and how they may impact potential new therapeutics. Here we examine how DNA methylation contributes to sex specific stress vulnerability in adult animals. Mice of both sexes were exposed to variable stress and given a behavioral test battery to examine stress sensitivity. Female mice expressed depressionassociated behavior across all tests stress exposure whereas males were behaviorally resilient. Markers of pre and post-synaptic plasticity and spine morphology were examined using a combination o…
TALPID3/KIAA0586 Regulates Multiple Aspects of Neuromuscular Patterning During Gastrointestinal Development in Animal Models and Human
2021
TALPID3/KIAA0586 is an evolutionary conserved protein, which plays an essential role in protein trafficking. Its role during gastrointestinal (GI) and enteric nervous system (ENS) development has not been studied previously. Here, we analyzed chicken, mouse and human embryonic GI tissues with TALPID3 mutations. The GI tract of TALPID3 chicken embryos was shortened and malformed. Histologically, the gut smooth muscle was mispatterned and enteric neural crest cells were scattered throughout the gut wall. Analysis of the Hedgehog pathway and gut extracellular matrix provided causative reasons for these defects. Interestingly, chicken intra-species grafting experiments and a conditional knockou…
