Isatis tinctoria L.—From Botanical Description to Seed-Extracted Compounds and Their Applications: An Overview
No full textInternational audienceIsatis tinctoria L. (Brassicaceae), also known as woad or dyer’s woad, is an ancient plant with a rosy future ahead. Most of the knowledge about woad is related to indigo dye production and its medicinal applications, especially its leaves. The general interest in woad has decreased with the rise of petroleum-based products. However, nowadays this plant is attracting interest again with industries reintroducing natural dyes. To meet the market demand in a sustainable manner, recent studies have focused specifically on woad seeds, leading to a valorization of the whole woad plant. This review provides an overview of the botanical, phytochemical composition, and properties of woad seeds, primarily supporting their cosmetic and pharmaceutical potential. From a chemical point of view, woad seeds mainly contain fatty acids, amino acids, phytosterols and glucosinolates. These compounds have been investigated through their extraction and analytical methods, as well as their properties and industrial applications

Exploring perceived barriers to physical activity among individuals with type 1 diabetes in the era of new technologies: An Analysis from the BETTER registry.
No full textInternational audienceObjectiveWe aimed to identify barriers to physical activity for people living with type 1 diabetes (PwT1D) and their relationship with sociodemographic and disease-specific factors.Methods- Cross-sectional study with BETTER registry participants (>14 years) who completed the BAPAD1 (Barriers to Physical Activity in T1D) questionnaire. An item with a score of 5 or more was defined as a barrier. Participants were categorized into 4 subgroups based on their insulin therapy and blood glucose monitoring modality: 1) multiple daily injections (MDI) without continuous glucose monitoring (CGM), 2) MDI with CGM, 3) continuous subcutaneous insulin infusion (CSII) with CGM, and 4) automated insulin delivery system (AID).ResultsAmong 1117 participants, the main perceived barrier was fear of hypoglycemia. BAPAD1 scores were similar across all subgroups, but more individuals in the AID group perceived "fear of hypoglycemia" and "loss of control over diabetes" as barriers. Being female, having a low income or education level, being overweight or obese, taking medication for depression, younger diabetes, higher HbA1c, presence of microvascular complications, and lack of confidence in managing hypoglycemia were associated with higher BAPAD1 score.ConclusionFear of hypoglycemia remains the main barrier to physical activity for PwT1D. Technological advances alone are not sufficient to reduce perceived barriers to physical activity, highlighting the need for complementary educational and behavioral interventions
Les valeurs multizétas tridendriformes et dendriformes par les arbres de Schroeder
No full textTo build new generalisations of Multiple Zeta Values, we define new spaces of formal series and formal integrals. We show that they are tridendriform and dendriform algebras. This allows us to reinterpret the fact that Multiple Zeta Values are algebra morphisms for shuffles of words in terms of finer tridendriform and dendriform structures. Applying universal properties of Schroeder trees we obtain generalisations of Multiple Zeta Values that are algebra morphisms for associative products. Hence we find new properties of Arborified Zeta Values and state how this enables the computation of some Shintani Zeta Values.Nous construisons de nouvelles généralisations des valeurs multizétas, nous définissons des nouveaux espaces de séries formelles et d'intégrales formelles. Nous montrons qu'il s'agit d'algèbres tridendriformes et dendriformes. Le fait que les fonctions multizétas soient des morphismes d'algèbres pour le produit de mélange des mots peut être réinterprété dans des structures tridendriformes et dendriformes. En appliquant des propriétés universelles propres aux arbres de Schroeder, nous obtenons des généralisations des fonctions multizétas qui restent des morphismes d'algèbres pour des produits associatifs. Ainsi, nous trouvons de nouvelles propriétés des multizétas arborifiées et nous remarquons que cela permet d'effectuer des calculs pour des fonctions multizétas de Shintani
