Metabolomic Mapping of Greek Olive Leaves by Untargeted NMR‐Based Profiling and LC–HRMS Dereplication

Analytical Science Advances, Volume 7, Issue 2, December 2026.
ABSTRACT Olive tree leaves are phytochemically rich yet insufficiently valorised in terms of systematic cultivar‐based characterisation and exploitation, and are an abundant olive industry side‐product. This study represents the first large‐scale metabolome mapping based on 340 leaf extracts from five major Greek cultivars (Amfissis, Koroneiki, Manaki,

Melanoma and Other Melanistic Lesions in Brown Bullhead Ameiurus nebulosus From Waterbodies in the Northeastern United States and Canada: Identification of Risk Factors

Journal of Fish Diseases, Volume 49, Issue 11, November 2026.
ABSTRACT Melanistic lesions, including non‐raised black areas due to proliferations of melanocytes and melanomacrophages in the dermis and epidermis, as well as raised black areas consistent with melanoma, are described in brown bullhead (BBH) Ameiurus nebulosus from three water bodies in the northeastern United States and Quebec, Canada.

Systematic Optimization of an SLE‐DAPTAD LC–MS/MS Workflow for Simultaneous Quantification of Low‐Abundance Vitamin D3 Metabolites in Plasma

Rapid Communications in Mass Spectrometry, Volume 40, Issue 20, 30 October 2026.
ABSTRACT Rationale Liquid chromatography–tandem mass spectrometry (LC–MS/MS) analysis of vitamin D3 metabolites is analytically challenging because these compounds are structurally similar, strongly matrix‐associated, and have poor ionization efficiency.

The Skin‐Lightening Efficacy and Mechanisms of Botanical Extracts: A Comprehensive Review [PDF]

J Cosmet Dermatol
ABSTRACT Background Skin pigmentation is regulated by a complex network involving melanogenesis, melanosome transfer, oxidative stress, environmental stimuli, and epidermal turnover. Botanical extracts and phytochemicals have attracted increasing interest as potential skin‐lightening agents. This review evaluates their efficacy, mechanisms, and safety.
