Modulation of Irisin and Physical Activity on Executive Functions in Obesity and Morbid obesity

2016

Whether the executive profile is different between obesity (OB) and morbid obesity (MO) remains unclear. Recent evidence suggests that physical activity (PA) can act as a cognitive enhancer. Irisin is a recently discovered hormone associated with some of the positive effects of PA. The objective of the study was to investigate the executive profile in OB and MO, and to explore the role of PA and irisin. 114 participants were included (21 OB, 44 MO and 49 healthy controls-HC) in the study and assessed with the Wisconsin Card Sorting Test, Stroop Color and Word Test, and Iowa Gambling Task. All participants were female, aged between 18 and 60 years. Results showed a similar dysfunctional prof…

I Cannot Place You: Dementia and the Pandemic Experience in The Visiting Hour by Frank McGuinness

2021

This paper presents a new play by Frank McGuinness, a play which was streamed to audiences in April 2021 and published a few weeks later. Set in contemporary Ireland, it focuses on two themes which seem to preoccupy its author: dementia, to which he devoted another play, Hanging Gardens and the consequences of living in a time of Pandemic. In particular, I argue, McGuinness indirectly seems to address an important question: how can literature and theatre offer an opportunity for reflecting about what is happening around us? Can literature help us to better understand and face the world? The play foregrounds the restorative power of emotional authenticity as we see a father and his daughter …

La demostración matemática: problemática actual

2002

RESUMENAnalizamos la problemática actual en torno a la demostración matemática, con particular énfasis en las ideas introducidas por las demostraciones asistidas por ordenador y por la llamada matemática experimental. Examinamos además la influencia que pueden tener estas ideas sobre el concepto de demostración y proponemos una caracterización atendiendo a las diferentes funciones que puede desempeñar la demostración en su vertientes explicativa, comunicativa, sistematizadora, como incrementadora de la comprensión de resultados y como transmisora de conocimiento y convicción. Finalmente, se ofrecen algunas conclusiones sobre problemas relacionados con la intuición, la lógica, la certeza, el…

'[I]t wasn’t in the picture and is not': Blind Spots and Vanishing Points in Irish Poetical Self-Portraits

2016

International audience; Pictoriality and a propensity for self-examination and self-representation are characteristic of the poetry of Louis MacNeice, Derek Mahon, Seamus Heaney and Paul Muldoon. In many a poem, these four contemporary Irish poets try to capture their own portraits in words and images, through highly visual poems often inspired by paintings. This paper first examines how these poets use images and invest paintings, how verbal and iconic texts interact in their creations and to what extent self-exegesis is made possible and more successful through ekphrasis. With reference to Jacques Derrida’s essay on self-portraiture—Memoirs of the Blind: Self-Portraits and Other Ruins—thi…

Interaction between mesenchymal cells and the posterior iris epithelium in chicken embryos

1977

The iris anlage of 3--10 day old chicken embryos was studied by both light and electron microscopy. Serial semithin sections showed that some of the mesenchymal cells overlying the eye cup moved into the primitive eye cavity by the 3rd day of incubation. On the 4th day some of these cells came into close contact with the basement membrane of the dorsal iris epithelium. The bases of the epithelial cells were flat at this stage. Towards the 10th day they formed cytoplasmic processes which did not penetrate the basement membrane. Fine mesenchymal cytoplasmic processes and a large number of extracellular fibrils developed in the epithelial--mesenchymal interface. The fine mesenchymal processes …

Metabolic Profile in a Cohort of Young Sicilian Patients with Klinefelter’s Syndrome: The Role of Irisin

2022

Klinefelter’s syndrome (KS) is the main cause of hypogonadism and infertility in men and is often related to obesity, metabolic syndrome, and diabetes. The purpose of our real-life observational study was to investigate the metabolic and anthropometric parameters in a population of patients with Klinefelter syndrome compared to a group of healthy age-matched subjects. Methods. In our study, 25 consecutive Caucasian adult outpatients (age range 21–52 years, mean age 32.9 ± 12.2) with KS in testosterone replacement therapy and 30 healthy men (age range 25–45 years, mean age 32.4 ± 7.62) were studied. In both groups of subjects, anthropometric indices, lipid profile, glucose metabolic paramete…

Varieties of agencies during working life changes

2020

The aim of this study is to shed light on the varieties of workers´ agencies in working life change situations, which is an under-researched topic in the literature of workplace learning and in working life studies. The research questions are what kinds of agencies there are to be found when workers encounter changes and how the different kinds of agencies are connected together. The understanding of agency is grounded on the subject-centered socio-cultural approach, whereas the methodological approach is based on applying life-course perspective on research material consisting of 48 working life narratives written by Finnish adults. The narratives are analyzed by abductive content analysis…
