The gene environment aetiology of freezing and its relationship with internalizing symptoms during adolescence.

EBioMedicine

July 2022

Donders Institute for Brain Cognition and Behaviour: Centre for Cognitive Neuroimaging (DCCN). Kapitelweg 29, P.O. Box 9104, 6500 HE Nijmegen, The Netherlands; Behavioural Science Institute, Radboud University, Thomas van Aquinostraat 4, 6525 GD Nijmegen, Netherlands.

Background: The freezing response is a universal response to threat, linked to attentive immobility and action preparation. It is relevant for acute stress coping in animals and humans, and subtle deviations in toddler freezing duration (absence of, or excessively long reactions) have been linked to higher risk for internalizing symptoms in adolescence. Yet, while individual freezing tendencies are relatively stable throughout life, little is known about their gene-environment aetiology.

Combining multilayered wrinkled polymer SERS substrates and spectral data processing for low concentration analyte detection.

Anal Bioanal Chem

July 2022

Département de Chimie, Quebec Center for Advanced Materials, Regroupement Québécois Sur Les Matériaux de Pointe, and Centre Interdisciplinaire de Recherche Sur Le Cerveau Et L'apprentissage, Université de Montréal, CP. 6128 Succ. Centre-Ville, Montréal, QC, H3C 3J7, Canada.

A series of thermally shrinkable polymer surface-enhanced Raman scattering (SERS) substrates were prepared with bimetallic Au and Ag (oxidized or not) films and with Au nanoparticles (AuNPs) located at different places in the layered structure to evaluate the synergistic effect of different known SERS amplification methods to enhance the Raman signal for low concentration dopamine detection. A bimetallic Au and Ag layered structure improved the Raman signal by 5 and 2 times compared to the single-layered Au and Ag films. Oxidizing the Ag layer prior to deposition of Au further improved the signal by a factor of 2, while adding AuNP on wrinkled films increased another 10 times the intensity of the Raman signal.

Red Absorbing Cyclometalated Ir(III) Diimine Photosensitizers Competent for Hydrogen Photocatalysis.

Inorg Chem

April 2022

Institut de la Matière Condensée et des Nanosciences (IMCN), Molecular Chemistry, Materials and Catalysis (MOST), Université catholique de Louvain (UCLouvain), Place Louis Pasteur 1, bte L4.01.02, Louvain-la-Neuve 1348, Belgium.

Two new cyclometalated Ir(III) diimine complexes were used as photosensitizers for homogeneous hydrogen evolution reaction (HER). These complexes were characterized by electrochemistry, ultraviolet-visible absorption, time-resolved and steady-state photoluminescence spectroscopy as well as by theoretical methods. The metal-ligand-to-ligand charge transfer character of their lowest excited state was shown to be competent for efficient H photoproduction in the presence of [Co(dmgH)(py)Cl] as the hydrogen evolution catalyst, triethanolamine as the sacrificial electron donor, and HBF as the proton source.

The trisaccharide, prop-2-ynyl 5-acetamido-3,5-dideoxy-d-glycero-α-d-galacto-2-nonulopyranosylonic acid-(2 → 3)-β-d-galactopyranosyl-(1 → 4)-2-acetamido-2-deoxy-β-d-glucopyranoside (9) has been efficiently synthesized in a few steps without the need of conformationally constrained glycosyl donors and acceptors or enzymes. First, using the known prop-2-ynyl 2-acetamido-2-deoxy-6-O-tert-butyldiphenylsilyl-β-d-glucopyranoside as acceptor (2) and the peracetylated galactosyl trichloroacetimidate (3) as glycosyl donor, followed by protecting groups manipulation, prop-2-ynyl (6-O-tert-butyldiphenylsilyl-β-d-galactopyranosyl)-(1 → 4)-2-acetamido-2-deoxy-6-O-tert-butyldiphenylsilyl-β-d-glucopyranoside (6) was synthesized with exclusive O-4 regioselectivity due to steric hindrance of the upper face of the acceptor at O-3. Sialylation with the thiophenyl glycosyl donor (7) afforded the desired trisaccharide with the shortest number of steps and in higher overall yield than previously reported methodologies.

A pragmatic randomized controlled trial of a group self-management support program versus treatment-as-usual for anxiety disorders: study protocol.

BMC Psychiatry

February 2022

Centre de recherche Charles-Le Moyne, Department of Community Health Sciences, Faculty of Medicine and Health Sciences, Université de Sherbrooke, 3001, 12th Avenue North, Sherbrooke (Quebec), J1H 5N4, Canada.

Background: The integration of a personal recovery-oriented practice in mental health services is an emerging principle in policy planning. Self-management support (SMS) is an intervention promoting recovery that aims at educating patients on the nature of their mental disorder, improving their strategies to manage their day-to-day symptoms, fostering self-efficacy and empowerment, preventing relapse, and promoting well-being. While SMS is well established for chronic physical conditions, there is a lack of evidence to support the implementation of structured SMS programs for common mental disorders, and particularly for anxiety disorders.

Pathways for cross-boundary effects of biodiversity on ecosystem functioning.

Trends Ecol Evol

May 2022

Geobotany, Faculty of Biology, University of Freiburg, Schaenzlestr. 1, 79104 Freiburg, Germany; Department of Renewable Resources, Faculty of Agriculture, Life, and Environmental Sciences, University of Alberta, Edmonton, Alberta, Canada, T6G 2H1.

The biodiversity-ecosystem functioning concept asserts that processes in ecosystems are markedly influenced by species richness and other facets of biodiversity. However, biodiversity-ecosystem functioning studies have been largely restricted to single ecosystems, ignoring the importance of functional links - such as the exchange of matter, energy, and organisms - between coupled ecosystems. Here we present a basic concept and outline three pathways of cross-boundary biodiversity effects on ecosystem processes and propose an agenda to assess such effects, focusing on terrestrial-aquatic linkages to illustrate the case.
