Síndrome de déficit de testosterona y disfunción eréctil
2010
OBJETIVOS Analizar la relacion entre el sindrome de deficit de testosterona (SDT) y la disfuncion erectil y sus implicaciones diagnosticas y terapeuticas. METODOS Revision bibliografica mediante la base de datos de Pubmed de la US National Library of Medicine. RESULTADOS La real prevalencia del SDT es desconocida, debido a la falta de criterios diagnosticos uniformes en cuanto a que fraccion de testosterona debe medirse (total, libre o biodisponible) y cuales deben ser los valores diagnosticos. A pesar de ello, se estima que entre un 5-15% de varones con disfuncion erectil presentan niveles sericos disminuidos de testosterona. Existe una solida base experimental que demuestra que la testost…

Riflessi dell'etnomusicologia in Sicilia: la "Due canzoni natalizie etnee trascritte dalla memoria per 11 strumenti" (1982-83) di Francesco Pennisi
2022
The text starts from some reflections on ethnomusicological research in Sicily and on the relationship between cultured composers and music of oral tradition. In particular, the genesis and compositional structure of the "Two Etna Christmas Songs transcribed from memory" of 1982-83 is reconstructed.

Studenti universitari: una riflessione
2021
The presence of foreign students in Italian universities intersects with the debate on citizenship, cooperation, integration and the opportunities offered by the labour market. Moreover, talking about foreign students enrolled in Universities implies the need to remember the heterogeneity between the types of students in relation not only to their origin, their motivations in choosing a course, but also to the problems connected to their legal status. In the text, reference will be made to data on foreign students who, at the end of their high school education, decided to continue their university studies by enrolling in a first-level or single-cycle university course in Italian universitie…
Nandrolone decanoate interferes with testosterone biosynthesis altering blood-testis barrier components
2017
Abstract The aim of this study was to investigate whether nandrolone decanoate (ND) use affects testosterone production and testicular morphology in a model of trained and sedentary mice. A group of mice underwent endurance training while another set led a sedentary lifestyle and were freely mobile within cages. All experimental groups were treated with either ND or peanut oil at different doses for 6 weeks. Testosterone serum levels were measured via liquid chromatography–mass spectrometry. Western blot analysis and quantitative real‐time PCR were utilized to determine gene and protein expression levels of the primary enzymes implicated in testosterone biosynthesis and gene expression leve…
Gut microbiota steroid sexual dimorphism and its impact on gonadal steroids: influences of obesity and menopausal status
2020
[Background]: Gonadal steroid hormones have been suggested as the underlying mechanism responsible for the sexual dimorphism observed in metabolic diseases. Animal studies have also evidenced a causal role of the gut microbiome and metabolic health. However, the role of sexual dimorphism in the gut microbiota and the potential role of the microbiome in influencing sex steroid hormones and shaping sexually dimorphic susceptibility to disease have been largely overlooked. Although there is some evidence of sex-specific differences in the gut microbiota diversity, composition, and functionality, the results are inconsistent. Importantly, most of these studies have not taken into account the go…
Effects of age and soccer expertise on general tests of perceptual and motor performance among adolescent soccer players.
2010
This study of perceptual and motor skills in soccer players was conducted on adolescent males. The goals were to monitor the development of general perceptual motor skills in nonsoccer-playing and soccer-playing groups ( n = 245), to examine the relationship between physical maturity and general perceptual motor skills ( n = 41), and to compare the differences in general perceptual motor skills between groups with different soccer expertise ( n = 142). The measured variables were simple reaction time, peripheral awareness, eye–hand–foot coordination, and testosterone blood level. The results suggested that general perceptual motor skills improved with age, the development of these skills w…
Socioeconomic position, immune function, and its physiological markers
2021
Abstract The development of costly traits such as immune function and secondary sexual traits is constrained by resource availability. The quality of developmental conditions and the availability of resources in ontogeny may therefore influence immune system functions and other biological traits. We analyzed causal pathways between family socioeconomic position, strength of immune response, and five physiological biomarkers in young Latvian men (n = 93) using structural equation modeling. Men from wealthier families had higher testosterone levels (rs = 0.280), stronger immune response (rs = 0.551), and higher facial attractiveness (rs = 0.300). There were weak, non-significant correlations …
