More than 15 million people have been affected by coronavirus disease 2019 (COVID‐19) and it has caused 640 016 deaths as of July 26, 2020. Currently, no effective treatment option is available for COVID‐19 patients. Though many drugs have been proposed, none of them has shown particular efficacy in clinical trials. In this article, the relationship between the Adrenergic system and the renin‐angiotensin‐aldosterone system (RAAS) is focused in COVID‐19 and a vicious circle consisting of the Adrenergic system‐RAAS‐Angiotensin converting (...) enzyme 2 (ACE2)‐severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) (which is referred to as the “ARAS loop”) is proposed. Hyperactivation of the ARAS loop may be the underlying pathophysiological mechanism in COVID‐19, and beta‐adrenergic blockers are proposed as a potential treatment option. Beta‐adrenergic blockers may decrease the SARS‐CoV‐2 cellular entry by decreasing ACE2 receptors expression and cluster of differentiation 147 (CD147) in various cells in the body. Beta‐adrenergic blockers may decrease the morbidity and mortality in COVID‐19 patients by preventing or reducing acute respiratory distress syndrome (ARDS) and other complications. Retrospective and prospective clinical trials should be conducted to check the validity of the hypothesis. Also see the video abstract here https://youtu.be/uLoy7do5ROo. (shrink)

Noradrenergic pathways are involved in mediating the central and peripheral effects of physiological arousal. The aim of the present study was to investigate the role of noradrenergic transmission in moral decision-making. We studied the effects in healthy volunteers of propranolol (a noradrenergic beta-adrenoceptor antagonist) on moral judgement in a set of moral dilemmas pitting utilitarian outcomes (e.g., saving five lives) against highly aversive harmful actions (e.g., killing an innocent person) in a double-blind, placebo-controlled, parallel group design. Propranolol (40 mg (...) orally) significantly reduced heart rate, but had no effect on self-reported mood. Importantly, propranolol made participants more likely to judge harmful actions as morally unacceptable, but only in dilemmas where harms were ‘up close and personal’. In addition, longer response times for such personal dilemmas were only found for the placebo group. Finally, judgments in personal dilemmas by the propranolol group were more decisive. These findings indicate that noradrenergic pathways play a role in responses to moral dilemmas, in line with recent work implicating emotion in moral decision-making. However, contrary to current theorising, these findings also suggest that aversion to harming is not driven by emotional arousal. Our findings are also of significant practical interest given that propranolol is a widely used drug in different settings, and is currently being considered as a potential treatment for post-traumatic stress disorder in military and rescue service personnel.

The human mind strives to maintain equilibrium between memory and oblivion and rejects irrelevant or disruptive memories. However, extensive amounts of stress hormones released at the time of a traumatic event can give rise to such powerful memory formation that traumatic memories cannot be rejected and do not vanish or diminish with time: Post-traumatic stress disorder may then develop. Recent scientific studies suggest that beta-blockers stopping the action of these stress hormones may reduce the emotional impact of disturbing (...) memories or prevent their consolidation. Using such an intervention could, in principle, help people who suffer from post-traumatic stress disorder, but the idea of doing so is controversial. I shall here discuss memory manipulation in this perspective. (shrink)

The usual strawsonian account of referring won't do for fictional entities. The problem is that we still don't have a sufficiently clear notion of ordinary referring, And the root of this problem is that referring is still perceived in terms of a paradigm relation of a description to an existing thing. But that relation is preceded by the more fundamental relation of thought to an object of thought, Whether real or imaginary. The conclusion reached is that fictional reference is an (...) institutionalized partial use of ordinary referring, Parasitic on it though leading a legitimate life of its own. (shrink)

An overview of Japanese philosophy from the seventh century to the present.

Blocker argues that the literary problem of absurdity is basically a metaphysical problem of being, focusing on the metaphysical distinction of being as essence and being as existence. This book compares philosophical prose with the fiction writing of four major absurdist writers—Camus, Sartre, Ionesco, and Beckett.

A defense of the embattled concept of aesthetic distance is achieved by reinstating a prominent feature of distance ignored in the current controversy. Distance is not the only supposed psychological posturing discussed by bullough, But also the space which is necessary to art between the art medium and the world represented therein. Examples from painting, Film and absurdist literature are discussed in terms of the historical tension between medium "opacity" and "transparency" in order to show how total transparency is avoided (...) to create the space between the art medium and reality, Without which art can neither "say" anything nor even exist.

This book brings philosophical aesthetics into a broader cultural interest in the fine arts and draws together the classics of the history of aesthetics, the mid-twentieth century or "Analytic" aesthetics, and late-twentieth century or "Continental" post-structuralist "theory.".
