01 Oct 2020TL;DR: Paradigmatic transition is the idea that ours is a time of transition between the paradigm of modernity, which seems to have exhausted its regenerating capacities, and another, emergent time, of which so far we have seen only signs as discussed by the authors.
Abstract: Paradigmatic transition is the idea that ours is a time of transition between the paradigm of modernity, which seems to have exhausted its regenerating capacities, and another, emergent time, of which so far we have seen only signs. Modernity as an ambitious and revolutionary sociocultural paradigm based on a dynamic tension between social regulation and social emancipation, the prevalent dynamic in the sixteenth century, has by the twenty-first century tilted in favour of regulation, to the determent of emancipation. The collapse of emancipation into regulation, and hence the impossibility of thinking about social emancipation consistently, symbolizes the exhaustion of the paradigm of modernity. At the same time, it signals the emergence of a new paradigm or new paradigms. This updated 2020 edition is written for students taking law and globalization courses, and political science, philosophy and sociology students doing optional subjects.

TL;DR: An efficient computational implementation of a path deletion K shortest paths algorithm and a new algorithm for the same problem that avoids the last K−1 executions of a shortest path algorithm are presented, resulting in a suprising and very substantial reduction in the execution time.

TL;DR: This work proposes that tau phosphorylation represents a compensatory response mounted by neurons against oxidative stress and serves a protective function, which opens a new window of knowledge with broad implications for both the understanding of mechanisms underlying disease pathophysiology and the design of new therapeutic strategies.

TL;DR: It is shown that BDNF acutely up-regulates the protein levels of AMPA receptor subunits in hippocampal neurons and induces the delivery ofAMPA receptors to the synapse.

TL;DR: There is evidence for the coexistence of two reciprocal antagonistic interactions between A(2A) and D(2) receptors in the same neurons, the GABAergic enkephalinergic neurons, which will have implications for the pathophysiology and treatment of basal ganglia disorders and drug addiction.
Abstract: Adenosine A(2A)-dopamine D(2) receptor interactions play a very important role in striatal function. A(2A)-D(2) receptor interactions provide an example of the capabilities of information processing by just two different G protein-coupled receptors. Thus, there is evidence for the coexistence of two reciprocal antagonistic interactions between A(2A) and D(2) receptors in the same neurons, the GABAergic enkephalinergic neurons. An antagonistic A(2A)-D(2) intramembrane receptor interaction, which depends on A(2A)-D(2) receptor heteromerization and G(q/11)-PLC signaling, modulates neuronal excitability and neurotransmitter release. On the other hand, an antagonistic A(2A)-D(2) receptor interaction at the adenylyl-cyclase level, which depends on G(s/olf)- and G(i/o)-type V adenylyl-cyclase signaling, modulates protein phosphorylation and gene expression. Finally, under conditions of upregulation of an activator of G protein signaling (AGS3), such as during chronic treatment with addictive drugs, a synergistic A(2A)-D(2) receptor interaction can also be demonstrated. AGS3 facilitates a synergistic interaction between G(s/olf) - and G(i/o)-coupled receptors on the activation of types II/IV adenylyl cyclase, leading to a paradoxical increase in protein phosphorylation and gene expression upon co-activation of A(2A) and D(2) receptors. The analysis of A(2)-D(2) receptor interactions will have implications for the pathophysiology and treatment of basal ganglia disorders and drug addiction.
