TL;DR: An overview of the use of coumarins compounds in medicinal chemistry in treating many diseases and applications is provided to contribute to the development of new rational research projects for the treatment and diagnosis of pathologies using coumarin derivatives.
Abstract: Coumarins are natural products characterized as 1,2 benzopyrones widely distributed in plants, as well as, in many species of fungi and bacteria. Nowadays, many synthetic procedures allow the discovery of coumarins with expanded chemical space. The ability to exert noncovalent interactions with many enzymes and receptors in live organisms lead the coumarins to exhibit a wide range of biological activities and applications. Then, this manuscript provides an overview of the use of coumarins compounds in medicinal chemistry in treating many diseases. Important examples of the last years have been selected concerning the activities of coumarins as anticoagulant, anticancer, antioxidant, antiviral, anti-diabetics, anti-inflammatory, antibacterial, antifungal and anti-neurodegerative agents. Additionally, it also includes applications of coumarins as fluorescent sensors for biological systems. Thus, this work aims to contribute to the development of new rational research projects for the treatment and diagnosis of pathologies using coumarin derivatives.

TL;DR: The results suggested the prevalence of a resilient core microbial community that did not suffer any change related to land use, soil type or edaphic conditions and illustrated that the history of land use might influence present-day community structure.

TL;DR: In this paper, the authors used the Tsallis nonextensive statistical formulation of the Friedmann equation to explore the Barboza-Alcaniz and Chevalier-Polarski-Linder parametric dark energy models and the Wang-Meng and Dalal vacuum decay models.
Abstract: The accelerated expansion of the Universe is one of the greatest challenges of modern physics. One candidate to explain this phenomenon is a new field called dark energy. In this work we have used the Tsallis nonextensive statistical formulation of the Friedmann equation to explore the Barboza–Alcaniz and Chevalier–Polarski–Linder parametric dark energy models and the Wang–Meng and Dalal vacuum decay models. After that, we have discussed the observational tests and the constraints concerning the Tsallis nonextensive parameter. Finally, we have described the dark energy physics through the role of the q -parameter.

TL;DR: In this article, an alternative interpretation of the dynamical evolution of the Friedmann-Robertson-Walker universe was proposed, with the aid of Verlinde's formalism, based on the relationship between thermodynamics and gravity.
Abstract: Based on the relationship between thermodynamics and gravity we propose, with the aid of Verlinde's formalism, an alternative interpretation of the dynamical evolution of the Friedmann-Robertson-Walker Universe. This description takes into account the entropy and temperature intrinsic to the horizon of the universe due to the information holographically stored there through non-gaussian statistical theories proposed by Tsallis and Kaniadakis. The effect of these non-gaussian statistics in the cosmological context is to change the strength of the gravitational constant. In this paper, we consider the wCDM model modified by the non-gaussian statistics and investigate the compatibility of these non-gaussian modification with the cosmological observations. In order to analyze in which extend the cosmological data constrain these non-extensive statistics, we will use type Ia supernovae, baryon acoustic oscillations, Hubble expansion rate function and the linear growth of matter density perturbations data. We show that Tsallis' statistics is favored at 1σ confidence level.
