Carbonic anhydrase 2-derived drug-responsive domain regulates membrane-bound cytokine expression and function in engineered T cells.

Adoptive cell therapies (ACT) have shown reduced efficacy against solid tumor malignancies compared to hematologic malignancies, partly due to the immunosuppressive nature of the tumor microenvironment (TME). ACT efficacy may be enhanced with pleiotropic cytokines that remodel the TME; however, their expression needs to be tightly controlled to avoid systemic toxicities. Here we show T cells can be armored with membrane-bound cytokines with surface expression regulated using drug-responsive domains (DRDs) developed from the 260-amino acid protein human carbonic anhydrase 2 (CA2).

Gender-Affirming Voice Therapy Duration and Satisfaction: Experiences from a Single Institution.

Objective: Current literature involving gender-affirming voice therapy (GAVT) for transgender and nonbinary (TGNB) individuals is limited. This study describes treatment duration and satisfaction at a single institution.

Study Design: Retrospective cohort.

10-Fold Increase in Hydrogen Atom Transfer Reactivity for a Series of = 1 Fe═O Complexes Over the = 2 [(TQA)Fe═O] Complex via Entropic Lowering of Reaction Barriers by Secondary Sphere Cycloalkyl Substitution.

Nonheme iron enzymes utilize = 2 iron(IV)-oxo intermediates as oxidants in biological oxygenations. In contrast, corresponding synthetic nonheme Fe═O complexes characterized to date favor the = 1 ground state that generally shows much poorer oxidative reactivity than their = 2 counterparts. However, one intriguing exception found by Nam a decade ago is the = 1 [Fe(O)(MeNTB)] complex (MeNTB = [tris((-methyl-benzimidazol-2-yl)methyl)amine], ) with a hydrogen atom transfer (HAT) reactivity that is 70% that of the = 2 [Fe(O)(TQA)] complex (TQA = tris(2-quinolylmethyl)amine, ).

Long Sleep Duration, Cognitive Performance, and the Moderating Role of Depression: A Cross-Sectional Analysis in the Framingham Heart Study.

Introduction: We investigated whether depression modified the associations between sleep duration and cognitive performance.

Methods: Multivariable linear regression models examined the associations between sleep duration and cognition in 1,853 dementia- and stroke-free participants from the Framingham Heart Study. Participants were categorized in four groups: no depressive symptoms, no antidepressants; depressive symptoms without antidepressants use; antidepressant use without depressive symptoms; both depressive symptoms and antidepressant use.
