A meta-analysis on individual differences in primary emotional systems and Big Five personality traits.

Sci Rep 2021 Apr 2;11(1):7453. Epub 2021 Apr 2.

Department of Molecular Psychology, Institute for Psychology and Education, Ulm University, Helmholtzstraße 8/1, 89081, Ulm, Germany.

The Affective Neuroscience Personality Scales (ANPS) were constructed as a self-report assessment to measure individual differences in Jaak Panksepp's cross-species primary emotional systems: SEEKING, PLAY, CARE (positive emotions) and FEAR, SADNESS, ANGER (negative emotions). Beginning with the first published work on the ANPS in 2003, individual differences on the ANPS measures of these six primary emotional systems have been consistently linked to Big Five personality traits. From a theoretical perspective, these primary emotional systems arising from subcortical regions, shed light on the nature of the Big Five personality traits from an evolutionary perspective, because each of these primary emotional systems represent a tool for survival endowing mammalian species with inherited behavioral programs to react appropriately to complex environments.

How Can Malnutrition Affect Autophagy in Chronic Heart Failure? Focus and Perspectives.

Int J Mol Sci 2021 Mar 24;22(7). Epub 2021 Mar 24.

Department of Internal Medicine, University of Cagliari, 09124 Cagliari, Italy.

Chronic heart failure (CHF) is a disease with important clinical and socio-economic ramifications. Malnutrition and severe alteration of the protein components of the body (protein disarrangements), common conditions in CHF patients, are independent correlates of heart dysfunction, disease progression, and mortality. Autophagy, a prominent occurrence in the heart of patients with advanced CHF, is a self-digestive process that prolongs myocardial cell lifespan by the removal of cytosolic components, such as aging organelles and proteins, and recycles the constituent elements for new protein synthesis.

Role of Charge Transfer in Halogen Bonding.

J Phys Chem A 2021 Apr 2;125(14):2944-2953. Epub 2021 Apr 2.

Department of Nanoscience, Joint School of Nanoscience and Nanoengineering, University of North Carolina at Greensboro, Greensboro, North Carolina 27401, United States.

Halogen bonding has received intensive attention recently for its applications in the construction of supramolecular assemblies and crystal engineering and its implications and potentials in chemical and biological processes and rational drug design. Peculiarly, in intermolecular interactions, halogen atoms are known as electron-donating groups carrying partial negative charges in molecules due to its high electronegativity, but they can counterintuitively act as Lewis acids and bind with Lewis bases in the form of a halogen bond. The unsettling issue regarding the nature of the halogen bonding is whether the electrostatics or charge transfer interaction dominates. Read More

Do Changes in Synaptic Autophagy Underlie the Cognitive Impairments in Huntington's Disease?

J Huntingtons Dis 2021 Mar 23. Epub 2021 Mar 23.

Department of Neurology, Columbia University, New York, NY, USA.

Although Huntington's disease (HD) is classically considered from the perspective of the motor syndrome, the cognitive changes in HD are prominent and often an early manifestation of disease. As such, investigating the underlying pathophysiology of cognitive changes may give insight into important and early neurodegenerative events. In this review, we first discuss evidence from both HD patients and animal models that cognitive changes correlate with early pathological changes at the synapse, an observation that is similarly made in other neurodegenerative conditions that primarily affect cognition.

Public Epistemologies and Intellectual Interventions in Contemporary Italy.

Int J Polit Cult Soc 2021 21;34(1):47-68. Epub 2019 Dec 21.

University of Cambridge, Cambridge, UK.

Building on recent work in the sociology of intellectual interventions, the study of cultural boundaries of science, and the role of ideas in politics, the article develops a theory of public epistemologies as argumentative tools people use to support or oppose political positions. Two prominent public epistemologies that have recently crystallized in Italian politics are taken as illustrations, with special attention paid to the role of two academics (an economist and an immunologist) turned public intellectuals. The article argues that the rise of populism in Italy has contributed to unusual alignments between political and epistemological positions, which has made questions about science and expert knowledge much more relevant in contesting and supporting political decisions.
