The importance of anion-π interactions as a driving force for chemical and biological processes is increasingly being recognized. In this communication, we describe for the first time its key participation in light-induced reactions. We show, in particular, how transient complexes formed through noncovalent anion-π interactions between electron-poor N-aryloxyamides and multiply-charged anions (such as carbonate or phosphate) can undergo facile light-promoted N-O cleavage, affording amidyl radicals that can subsequently be trapped by (hetero)aromatics.

Introduction: Unmet health care needs are seen as a key indicator of equity in access to health care. With younger people, they can lead to poorer health outcomes in adulthood, and in older people they can be associated with an increased risk of mortality. The presence of a disability is considered a risk factor for unmet needs.

Controlling hypertension has become an important issue in the elderly population in whom neurological comorbidities are highly prevalent. Most of the large-scale trials focusing on hypertension management in older populations have excluded patients with comorbid neurological disorders. However, this population requires special considerations, as the benefits of antihypertensive agents are mostly uncertain and there is a higher risk of adverse events.

Background: Candida albicans is the primary cause of vulvovaginal candidiasis, a worldwide health concern for women. The use of supplemental methods, such as antimicrobial photodynamic therapy (aPDT) and probiotics, was promoted by the ineffectiveness of the existing antifungal drugs.
Methods: This study examines the combined effects of probiotics (Bacillus and Enterococcus isolated from the fermented pickles) and PDT (using red laser (655 nm, 18 J/cm) as a light source and methylene blue dye (30 mg/mL) as a photosensitizer) on the in vitro virulence activity of C.

B-box proteins (BBX) play pivotal roles in the regulation of numerous growth and developmental processes in plants, particularly the light-mediated biosynthesis of pigments. To elucidate the role of BBX transcription factors in the anthocyanin biosynthetic pathway of Lagerstroemia indica leaves, this study identified 41 BBX genes in the L. indica genome.
