- Exploring perceived barriers to physical activity among older adults living in low-population density regions: gender differences and associations with activity dimensionsPublication . Rúa-Alonso, María; Bovolini, Antonio; Costa-Brito, Ana Raquel; Vaz, Cláudia; Marques, Ermelinda; Serra, Nuno; Lopes, Vitor P.; Vila-Chã, CarolinaOlder people in low-population density regions tend to have fewer resources to engage in regular physical activity (PA) compared to their counterparts in urban areas. Moreover, PA assumes different dimensions, and the amount of PA related to each dimension may differ between women and men, predisposing them to different PA practices. Therefore, this cross-sectional study aims to describe the prevalence of barriers to PA, gender differences, and their associations with different PA dimensions. A total of 259 older adults (153 women and 106 men; age, 75.17 8.05 years old) living in the community in the region of Guarda (Portugal) were interviewed face to face to record their sociodemographic characteristics, general health status (comorbidity index and self-reported health), PA behaviour, and barriers to PA.Women were more likely to report “low” income and living alone (p 0.05), while men reported a higher negative health status than women (p < 0.05). Two intrinsic (“Fear of injury” (40.1%) and “Need for rest” (26.3%)) and two extrinsic barriers (“Lack of nearby facilities” (30.5%) and “I don’t have transport” (25.6%)) were the most prevalent. For women, age, self-reported health, comorbidity index, and intrinsic and extrinsic barriers were similarly associated with the different PA dimensions. However, only self-reported health and extrinsic barriers were the variables associated with the different PA dimensions in men. Therefore, strategies to promote active ageing in low-population density regions should be focused on reducing intrinsic and extrinsic barriers based on gender and the PA dimension to be achieved.
- Sulfur-containing compounds from fungiPublication . Garcia, Juliana; Silva, Jani; Gouvinhas, Irene; Guimarães, Rafaela; Bovolini, Antonio; Saavedra, Maria José; Alves, Maria JoséSulfur contributes greatly to the chemical richness of nature and, due to its unique properties, enables essential biological interactions that no other element can. Sulfur-containing compounds are bioactive/nutraceuticals substances from different sources, including fungi. They comprise sulfur atoms that are cyclically or noncyclically bonded to a cyanate group or a carbon atom. Sulfur-containing compounds, already identified in various mushrooms species, include compounds such as ergothioneine (EGT), glutathione (GSH), and lenthionine (LT). These compounds exhibit important therapeutic properties such as antioxidant, antiinflammatory, anti-neurodegenerative, and antiplatelet characteristics potentially useful in the treatment of a variety of disorders and diseases, including neurodegenerative and cardiovascular diseases and even diabetes. The purpose of this chapter is to explain the generally recognized sulfur-containing compounds from fungi covering the distribution in species, and genera, as well as the extraction and identification by contemporary analytical techniques. The biosynthetic elements of fungal sulfur compounds, as well as the state of art concerning their biological activities, are also discussed.
