The Orienting Response in Healthy Aging: Novelty P3 Indicates No General Decline but Reduced Efficacy for Fast Stimulation Rates
2017
Automatic orienting to unexpected changes in the environment is a pre-requisite for adaptive behavior. One prominent mechanism of automatic attentional control is the Orienting Response (OR). Despite the fundamental significance of the OR in everyday life, only little is known about how the OR is affected by healthy aging. We tested this question in two age groups (19–38 years and 55–72 years) and measured skin-conductance responses (SCRs) and event-related brain potentials (ERPs) to novels (i.e., short environmental sounds presented only once in the experiment; 10% of the trials) compared to standard sounds (600 Hz sinusoidal tones with 200 ms duration; 90% of the trials). Novel and standa…
Walking Stroop carpet: an innovative dual-task concept for detecting cognitive impairment

However, current dual-task tests appear to be insufficient for early diagnosi…
Anti-senescence and Anti-inflammatory Effects of the C-terminal Moiety of PTHrP Peptides in OA Osteoblasts.
2016
Osteoarthritis (OA) is characterized by degenerative changes in the whole joint leading to physical disability in the elderly population. This condition is associated with altered bone metabolism in subchondral areas suggesting that therapeutic strategies aimed at modifying bone cell metabolism may be of interest. We have investigated the effects of several parathyroid hormone-related protein (PTHrP)-derived peptides (1-37): (N-terminal), (107-111) and (107-139) (C-terminal) on senescence features induced by inflammatory stress in human OA osteoblasts. Incubation of these primary cells with interleukin(IL)-1β led to an increased expression of senescence markers senescence-associated-β-galac…
Changes in spinal range of motion after a flexibility training program in elderly women
2014
Giuseppe Battaglia,1,2 Marianna Bellafiore,1,2 Giovanni Caramazza,2 Antonio Paoli,3 Antonino Bianco,1,2 Antonio Palma1,2 1Department of Law, Society, and Sport Sciences, University of Palermo, Palermo, Italy; 2Sicilian Regional Sports School of Italian National Olympic Committee (CONI), Sicily, Italy; 3Department of Biomedical Sciences, University of Padova, Padova, Italy Background: Aging-related reduced spinal mobility can interfere with the execution of important functional skills and activities in elderly women. Although several studies have shown positive outcomes in response to spinal flexibility training programs, little is known about the management of sets and repetitions in traini…
Experimental Procedures of Accelerated Aging and Evaluation of Effectiveness of Nanostructured Products for the Protection of Volterra (Italy) Panchi…
2022
The aims of the research were to evaluate the effectiveness of the application of nanostructured products on Volterra calcarenite stone and to define the experimental conditions and procedures of accelerated aging tests, able to simulate different degradation on the studied lithotype. The work focused on methods of performing accelerated aging tests in order to simulate different effects of environmental decay involving stone used on a historical site. The rock samples were examined before and after three treatment types: cyclic salt spray chamber, cycles of freezing–thawing and cycles of thermal shock. After each artificial aging cycle, changes in appearance were noted and chemical and phy…

Diet to Reduce the Metabolic Syndrome Associated with Menopause. The Logic for Olive Oil
2020
The rates of metabolic syndrome are increasing in parallel with the increasing prevalence of obesity, primarily due to its concomitant insulin resistance. This is particularly concerning for women, as the years around menopause are accompanied by an increase in visceral obesity, a strong determinant of insulin resistance. A fall in estrogens and increase in the androgen/estrogen ratio is attributed a determining role in this process, which has been confirmed in other physiological models, such as polycystic ovary syndrome. A healthy lifestyle, with special emphasis on nutrition, has been recommended as a first-line strategy in consensuses and guidelines. A consistent body of evidence has ac…
Rescue of ovarian function: stem cells and regenerative factors
2022
El envejecimiento y otras condiciones de daño adquiridas, como los tratamientos oncológicos, conducen a un deterioro de la función ovárica. Sin embargo, incluso cuando los ovarios dañados pierden su capacidad de ovular, permanece un conjunto residual de folículos quiescentes que podrían ser rescatados y desarrollados en un nicho ovárico adecuado, dando lugar a ovocitos maduros. Los factores solubles secretados por las células madre podrían proporcionar un entorno ovárico adecuado para mantener y promover el crecimiento folicular. Por lo tanto, la presente tesis doctoral tuvo como objetivo evaluar los efectos regenerativos de diferentes fuentes de factores secretados por células madre en mod…
Theologie des Alterns. Ein Beitrag von Papst Franziskus
2022
Obecny wzrost populacji osób starszych staje się nowym wyzwaniem dla teologii, w tym szczególnie antropologii teologicznej i teologii pastoralnej. Problem ten nie jest obcy aktualnemu nauczaniu papieskiemu. Świadczy o tym wyrażana przez papieży św. Jana Pawła II (1978–2005), Benedykta XVI (2005–2013) i Franciszka (2013–) troska o człowieka w podeszłym wieku w okolicznościowych przemówieniach, katechezach i homiliach. Zaangażowanie w promocję pozytywnej wizji starości i obronę godności osób starszych jest szczególnie obecne w nauczaniu papieża Franciszka. Celem artykułu była próba ukazania w świetle najnowszych rozważań papieża Franciszka o starości, z okazji ustanowienia 25 lipca 2021 roku …

Es una aproximación cualitativa al uso y percepción que tienen los mayores de 55 años, de las tecnologías de la comunicación e información (TIC); Concretamente del uso de las redes sociales online. Mediante la técnica de los grupos de discusión trataremos de buscar los prejuicios, mitos conocimientos, motivaciones, barreras, etc. del uso o no de las redes sociales online. It is a qualitative approach to the use and perception of over 55 years of technology and information communication technology (ICT), specifically the use of online social networks. By the technique of focus groups will try to find the prejudices, myths, knowledge, motivations, barriers, etc.. use or not online social netw…
