The Parkinson's disease associated protein α-synuclein (αS) has been found to contain numerous post-translational modifications (PTMs), in both physiological and pathological states. One PTM site of particular interest is serine 87, which is subject to both O-linked β-N-acetylglucosamine (gS) modification and phosphorylation (pS), with αS-pS enriched in Parkinson's disease. An often-overlooked aspect of these PTMs is their effect on the membrane-binding properties of αS, which are important to its role in regulating neurotransmitter release.

Associations between trauma-related guilt, symptoms of posttraumatic stress disorder, and problematic alcohol use.

Psychiatry Res

August 2023

Department of Psychiatry and Behavioral Sciences, Keck School of Medicine, University of Southern California, 669W 34th street, Los Angeles CA 90089, United Sates.

Trauma-related guilt, or a belief that one should have felt, thought, or acted differently during a traumatic event in which someone's life or physical integrity was threatened, has been consistently associated with mental health disorders such as posttraumatic stress disorder (PTSD). Theories of trauma-related guilt suggest that some avoidant coping behaviors, such as problematic alcohol use, are crucial pathways connecting trauma-related guilt to PTSD but have not been thoroughly investigated. The present study uses data from a longitudinal cohort of veterans to examine two models: the first assessed problematic alcohol use as a mechanism linking trauma-related guilt and PTSD.

Mediating Photochemical Reaction Rates at Lewis Acidic Rare Earths by Selective Energy Loss to 4f-Electron States.

J Am Chem Soc

August 2023

P. Roy and Diana T. Vagelos Laboratories, Department of Chemistry, University of Pennsylvania, 231 S. 34th Street, Philadelphia, Pennsylvania 19104, United States.

Manifesting chemical differences in individual rare earth (RE) element complexes is challenging due to the similar sizes of the tripositive cations and the corelike 4f shell. We disclose a new strategy for differentiating between similarly sized Dy and Y ions through a tailored photochemical reaction of their isostructural complexes in which the f-electron states of Dy act as an energy sink. Complexes RE(hfac)(NMMO) (RE = Dy () and Y (), hfac = hexafluoroacetylacetonate, and NMMO = -methylmorpholine--oxide) showed variable rates of oxygen atom transfer (OAT) to triphenylphosphine under ultraviolet (UV) irradiation, as monitored by H and F NMR spectroscopies.

Borane-Catalyzed Tandem Cyclization/Hydrosilylation Towards Enantio- and Diastereoselective Construction of trans-2,3-Disubstituted-1,2,3,4-Tetrahydroquinoxalines.

Angew Chem Int Ed Engl

August 2023

Roy and Diana Vagelos Laboratories, Penn/Merck Laboratory for High-Throughput Experimentation, Department of Chemistry, University of Pennsylvania, 231 South 34th Street, PA 19104-6323, Philadelphia, USA.

Recent years have witnessed marked progress in the efficient synthesis of various enantioenriched 1,2,3,4-tetrahydroquinoxalines. However, enantio- and diastereoselective access to trans-2,3-disubstituted 1,2,3,4-tetrahydroquinoxalines remains much less explored. Herein we report that a frustrated Lewis pair-based catalyst generated via in situ hydroboration of 2-vinylnaphthalene with HB(C F ) allows for the one-pot tandem cyclization/hydrosilylation of 1,2-diaminobenzenes and 1,2-diketones with commercially available PhSiH to exclusively afford trans-2,3-disubstituted 1,2,3,4-tetrahydroquinoxalines in high yields with excellent diastereoselectivities (>20 : 1 dr).

For decades, the spontaneous organization of nanocrystals into superlattices has captivated the scientific community. However, achieving direct control over the formation of the superlattice and its phase transformations has proven to be a grand challenge, often resulting in the generation of multiple symmetries under the same experimental conditions. Here, we achieve direct control over the formation of the superlattice and its phase transformations by modulating the thermal energy of a nanocrystal dispersion without relying on solvent evaporation.
