    All Work and No Play? Facilitating Serious Games and Gamified Applications in Participatory Urban Planning and Governance

    As games and gamified applications gain prominence in the academic debate on participatory practices, it is worth examining whether the application of such tools in the daily planning practice could be beneficial. This study identifies a research–practice gap in the current state of participatory urban planning practices in three European cities. Planners and policymakers acknowledge the benefits of employing such tools to illustrate complex urban issues, evoke social learning, and make participation more accessible. However, a series of impediments relating to planners’ inexperience with participatory methods, resource constraints, and sceptical adult audiences, limits the broader application of games and gamified applications within participatory urban planning practices. Games and gamified applications could become more widely employed within participatory planning processes when process facilitators become better educated and better able to judge the situations in which such tools could be implemented as part of the planning process, and if such applications are simple and useful, and if their development process is based on co-creation with the participating publics

    Mini is beautiful:Playing serious mini-games to facilitate collective learning on complex urban processes

    Spatial planning projects can be conceived as processes of collective learning. Planners have been looking at games and playful approaches to support these processes. Considering that planning projects are long and complex, we propose to not reason for single, full-fledged and all-encompassing games, but instead work with strings of, so-called, serious mini-games that each addresses a specific learning goal, guided by a collective learning model. This paper conceptualizes a toolbox to support the development and contextualization of such strings of serious mini-games

    Anticancer Activity of Natural and Synthetic Chalcones

    Cancer is a condition caused by many mechanisms (genetic, immune, oxidation, and inflammatory). Anticancer therapy aims to destroy or stop the growth of cancer cells. Resistance to treatment is theleading cause of the inefficiency of current standard therapies. Targeted therapies are the most effective due to the low number of side effects and low resistance. Among the small molecule natural compounds, flavonoids are of particular interest for theidentification of new anticancer agents. Chalcones are precursors to all flavonoids and have many biological activities. The anticancer activity of chalcones is due to the ability of these compounds to act on many targets. Natural chalcones, such as licochalcones, xanthohumol (XN), panduretin (PA), and loncocarpine, have been extensively studied and modulated. Modification of the basic structure of chalcones in order to obtain compounds with superior cytotoxic properties has been performed by modulating the aromatic residues, replacing aromatic residues with heterocycles, and obtaining hybrid molecules. A huge number of chalcone derivatives with residues such as diaryl ether, sulfonamide, and amine have been obtained, their presence being favorable for anticancer activity. Modification of the amino group in the structure of aminochalconesis always favorable for antitumor activity. This is why hybrid molecules of chalcones with different nitrogen hetercycles in the molecule have been obtained. From these, azoles (imidazole, oxazoles, tetrazoles, thiazoles, 1,2,3-triazoles, and 1,2,4-triazoles) are of particular importance for the identification of new anticancer agents

    Lipophilicity as a Central Component of Drug-Like Properties of Chalchones and Flavonoid Derivatives

    Lipophilcity is an important physico-chemical parameter that influences membrane transport and binding ability to action. Migration distance following complete elution of compounds was used to calculate different lipophilicity-related parameters. The aim of this study is to show that lipophilicity is a central component of thiazole chalcones and flavonoid derivatives regarding their drug-like properties. Experimental and computational methods were used. This study considers 44 previously synthesized compounds (thiazole chalcones, flavanones, flavones, 3-hydroxyflavones, and their acetylated derivatives). The concerned compounds have shown antitumoral hallmarks and antibacterial activity in vitro. The experimental method used to determine compounds’ lipophilicity was the reverse-phase thin layer chromatography (RP-TLC). Lipophilicity related parameters—isocratic retention factor (RM), relative lipophily (RM0), slope (b), chromatographic hydrophobic index (φ0), scores of principal components (PC1/RM)—were determined based on reverse-phase chromatography results

    Serious Games, Mental Images, and Participatory Mapping: Reflections on a Set of Enabling Tools for Capacity Building

    Increasing complexity of societal questions requires participatory processes that engage with capable participants. We adopted Horellis’ stance on participation as not an isolated event but a constant communication between different groups that can be assured by using enabling tools. We applied the Capability Approach to frame a capacity-building process and understand how this framework can support a collective of entrepreneurs to become aware of their capabilities (and the impact of an ongoing urban renewal process on these capabilities). The Capability Approach emphasizes the personal and structural conditions that impact a person’s capability to choose—the conditions that affect the process of determining what a person values. The paper builds on a two year capacity-building process conducted in Genk, Belgium, and proposes a conceptual framework for building capacities, in which the process and outputs collide with ideas of choice, ability, and opportunity, notions central to the Capability Approach. The case study looks at one of the main commercial streets of the city (Vennestraat) and reflects on a set of enabling artefacts used to engage proprietors in the capacity-building process. This capacity-building process, characterized by the idea of space and capabilities, advances a critical viewpoint on issues related to participatory processes and gives practitioners a set of enabling tools to start a conversation over complex urban transformations, such as the one in Vennestraat

    Two Important Anticancer Mechanisms of Natural and Synthetic Chalcones

    No full text
    ATP-binding cassette subfamily G and tubulin pharmacological mechanisms decrease the effectiveness of anticancer drugs by modulating drug absorption and by creating tubulin assembly through polymerization. A series of natural and synthetic chalcones have been reported to have very good anticancer activity, with a half-maximal inhibitory concentration lower than 1 µM. By modulation, it is observed in case of the first mechanism that methoxy substituents on the aromatic cycle of acetophenone residue and substitution of phenyl nucleus by a heterocycle and by methoxy or hydroxyl groups have a positive impact. To inhibit tubulin, compounds bind to colchicine binding site. Presence of methoxy groups, amino groups or heterocyclic substituents increase activity
