Scattering Studies with Low-Energy Kaon-Proton Femtoscopy in Proton-Proton Collisions at the LHC
2020
The study of the strength and behaviour of the antikaon-nucleon ($\mathrm{\overline{K}N}$) interaction constitutes one of the key focuses of the strangeness sector in low-energy Quantum Chromodynamics (QCD). In this letter a unique high-precision measurement of the strong interaction between kaons and protons, close and above the kinematic threshold, is presented. The femtoscopic measurements of the correlation function at low pair-frame relative momentum of (K$^+$ p $\oplus$ K$^-$ $\overline{\mathrm{p}}$) and (K$^-$ p $\oplus$ K$^+$ $\overline{\mathrm{p}}$) pairs measured in pp collisions at $\sqrt{s}$ = 5, 7 and 13 TeV are reported. A structure observed around a relative momentum of 58 Me…
Antidepressive-like Behavior-Related Metabolomic Signatures of Sigma-1 Receptor Knockout Mice
2022
Sigma-1 receptor (Sig1R) has been proposed as a therapeutic target for neurological, neu-rodegenerative, and psychiatric disorders, including depression and anxiety. Identifying metabolites that are affected by Sig1R absence and cross-referencing them with specific mood-related behaviors would be helpful for the development of new therapies for Sig1R-associated disorders. Here, we examined metabolic profiles in the blood and brains of male CD-1 background Sig1R knockout (KO) mice in adulthood and old age and correlated them with the assessment of depression-and anxiety-related behaviors. The most pronounced changes in the metabolic profile were observed in the plasma of adult Sig1R KO mice.…
Veinte años de intervención en drogodependencias: una perspectiva desde Proyecto Hombre de Valencia
2005
A lo largo de estos últimos veinte años, la realidad del consumo de drogas en nuestro país, y su evolución y cambios de paradigmas, ha sido una constante. En función de dichos cambios a su vez ha ido evolucionando la realidad de las intervenciones en este campo. Este artículo pretende ser una breve visión de esta evolución de veinte años desde la perspectiva de una organización como Proyecto Hombre en Valencia, evolución que también lo ha sido de esta misma organización, ya que hace precisamente veinte años iniciamos nuestra andadura con este propósito en la ciudad de Valencia y para toda la comunidad, para convertirnos en el referente que pretendemos ser hoy día.
Decorated pottery study: Analysis of pigments by x-ray absorbance spectroscopy measurements
2007
Characterization of pigments on decorated pottery fragments has been fully carried out by nondestructive x-ray absorbance spectroscopy (XAS). The samples were a series of pottery shards excavated from the archeological site of Caltagirone (Sicily, Italy), a well-known ceramic production center. Aesthetical criteria and morphological observations allowed us to attribute the samples to quite different historical periods, starting from the 18th century B.C. up to the 16th century A.D. An extensive time interval led us to suppose that different materials and techniques were used for the production of the ceramic paste and also for the preparation of pigments. XAS measurements were performed at …
Social suffering as structural and symbolic violence. LGBT experiences in the Face of AIDS film archive
2018
The chapter aims to summarize the main sociological approaches that acknowledge the link that exists between AIDS and the stigmatization of nonnormative sexual conducts and then we will address the issue of structural violence and how it can be discerned in the impact of HIV/AIDS on oppressed and marginalized groups on a global scale, as manifested in the Face of AIDS film archive.
Experiences of students with HIV/AIDS in rural, post-conflict Uganda
2015
The roll out of Anti-Retroviral Therapy across Sub-Saharan Africa has given rise to a new generation of adolescents that previously would not have survived into their teen years. The aim of this research is to give voice to these young people, specifically HIV positive students, in the rural, post-conflict area of Katakwi, Uganda. Through the lens of empowerment, which focuses on participation, capacity building, leadership potential, and relationships, this research examines the factors in these students’ lives that contribute to their empowerment, or the absence of these factors that then have the potential to disempower them. It considers the way the students themselves see both the prot…
Anorectal malformations and pregnancy-related disorders: a registry-based case-control study in 17 European regions
2013
Objective To identify pregnancy-related risk factors for different manifestations of congenital anorectal malformations (ARMs).Design A population-based case-control study.Setting Seventeen EUROCAT (European Surveillance of Congenital Anomalies) registries, 1980-2008.Population The study population consisted of 1417 cases with ARM, including 648 cases of isolated ARM, 601 cases of ARM with additional congenital anomalies, and 168 cases of ARM-VACTERL (vertebral, anal, cardiac, tracheo-esophageal, renal, and limb defects), along with 13371 controls with recognised syndromes or chromosomal abnormalities.Methods Multiple logistic regression analyses were used to calculate adjusted odds ratios …
Is mental health literacy for depression associated with the intention toward preventive actions? A cross-sectional study among university students
2021
Objective Mental Health Literacy (MHL) might play an important role in preventing depression. This study assessed the MHL level for depression of university students and its association with intentions toward preventive actions against depression. Participants: University students (n = 315) were surveyed online. Methods: MHL level and group differences were analyzed using t-tests and one-way ANOVA. To investigate the relation between MHL and the intention for preventive actions against depression, correlation and regression analyses were performed. Results: The mean MHL level of the participants was reasonably high (42.65 of 75 points). MHL levels differed significantly between different gr…
Trans-epithelial transport of the betalain pigments indicaxanthin and betanin across Caco-2 cell monolayers and influence of food matrix.
2012
Purpose: This study investigated the absorption mechanism of the phytochemicals indicaxanthin and betanin and the influence of their food matrix (cactus pear and red beet) on the intestinal transport. Methods: Trans-epithelial transport of dietary-consistent amounts of indicaxanthin and betanin in Caco-2 cell monolayers seeded on TranswellR inserts was measured in apical to basolateral (AP-BL) and basolateral to apical (BL-AP) direction, under an inwardly directed pH gradient (pH 6.0/7.4, AP/BL) mimicking luminal and serosal sides of human intestinal epithelium. The effect of inhibitors of membrane transporters on the absorption was also evaluated. Contribution of the paracellular route was…
Effect of simulated gastrointestinal digestion on plant sterols and their oxides in enriched beverages
2013
Abstract This study evaluates the bioaccessibility (percentage of soluble compound available for absorption) of plant sterols (PS) and their oxides (phytosterol oxidation products, POPs) after simulated gastrointestinal digestion in fruit (Fb), milk (M) and fruit-based milk beverages with (FbM a ) or without (FbM b ) tangerine juice. In beverages and their bioaccessible fraction (BF), campesterol, campestanol, stigmasterol, β-sitosterol and sitostanol were detected. Bioaccessibility of total PS ranged between 2.62 and 6.48%, FbM b yielding the highest value, followed by FbM a > Fb > M. Campesterol/campestanol were the most bioaccessible PS. Only oxides of β-sitosterol were detected in beve…
