Diagnosis and Dentists' Treatment Preferences for Vestibular Enamel Defects—A Cross‐Sectional Survey

Journal of Esthetic and Restorative Dentistry, Volume 38, Issue 11, Page 2124-2132, November 2026.
ABSTRACT Objectives Vestibular enamel defects, including WSL, MIH, or fluorosis, can impair esthetics and patient well‐being, making accurate diagnosis essential for selecting appropriate treatment strategies. However, distinguishing these based solely on clinical images—an increasingly common scenario in digital communication—can be challenging.

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.

A General Stereochemical Model for Grignard Additions to α‐Alkoxy Nitrones: Density Functional Theory Evidence for an Intrinsic α‐Chelation‐Controlled Pathway

European Journal of Organic Chemistry, Volume 29, Issue 40, 27 October 2026.
A comprehensive DFT conformational study of Grignard additions to α‐alkoxy nitrones reveals that the reaction proceeds through a dinuclear α‐chelated transition structure in which the nitrone oxygen coordinates two magnesium centers. Other common additives, such as zinc dichloride, boron trifluoride, and dimethylaluminum chloride, were also studied ...

Medicinal Chemistry Aspects of Thiazole and Thiazolidine Derivatives as Fundamental Building Blocks to Design New NNRTIs Against HIV‐1 Reverse Transcriptase

ChemMedChem, Volume 21, Issue 19, 14 October 2026.
HIV‐1 reverse transcriptase (HIV‐1 RT) is a polymerase enzyme and a key target in HIV‐1 therapy. The discovery of selective HIV‐1 RT inhibitors has highlighted thiazole scaffolds and their derivatives, thiazolidine‐2‐one and thiazolidine‐2,4‐dione, as promising structures for the rational design of novel non‐nucleoside reverse transcriptase inhibitors (

Endocrine disruptors and spontaneous premature labor: a case control study

Environmental Health, 2007
Background Premature labor is a poorly understood condition. Estrogen is thought to play a key role and therefore the labor process may be affected by endocrine disruptors.
