Sedimentary biogeochemical provinces in the northern limit of the oxygen minimum zone from the northeastern Mexican Pacific

open access: yesSedimentology, EarlyView.
ABSTRACT Continental margins are reservoirs of materials of terrestrial and marine origin, and they play a crucial role in understanding the spatial and temporal variability of biogeochemical cycles. This, in turn, provides insights into the development and intensity of oxygen minimum zones (OMZs).

Optical Coherence Tomography for Detection of Dental Cracks and Vertical Root Fracture: A Scoping Review

open access: yesClinical and Experimental Dental Research, Volume 12, Issue 2, April 2026.
ABSTRACT Objectives Vertical root fractures (VRFs) pose significant clinical challenges and may result in tooth loss. Current diagnostic methods, including conventional radiography and CBCT, are challenging to detect VRFs, especially in the early stages. Optical coherence tomography (OCT) has recently been introduced as a non‐invasive imaging technique

Information Gaps and Practical Barriers in the Recommendation of Cosmetic Products by Dermatologists: Evidence From a Brazilian Study

open access: yesDermatological Reviews, Volume 7, Issue 2, April 2026.
ABSTRACT Background The recommendation of cosmetic products in dermatological practice has become increasingly common, driven by the evolution of formulations and active ingredients that sometimes mirror pharmacological effects. This convergence has blurred the boundaries between cosmetics and medications, creating uncertainty among professionals ...

Strontium Incorporating Hypochlorous Acid as a Novel Conditioner for Improvement of Self‐Etch Adhesive Dentin Bond Performance

open access: yesNatural Sciences, Volume 6, Issue 2, April 2026.
ABSTRACT We developed a novel strontium‐incorporating hypochlorous acid (Sr/HOCl) conditioner to improve dental adhesive performance. Human dentin surfaces were pretreated with four protocols: untreated control, pure HOCl, HOCl with subsequent application of sulfinate agent (HOCl + SA), and Sr/HOCl.

Long‐Term Reorganization of Ocean Nutrient Distribution

open access: yesAGU Advances, Volume 7, Issue 2, April 2026.
Abstract Nutrient availability is a major driver of ocean biodiversity and productivity, yet long‐term global changes remain poorly constrained. Using over 14 million nitrate and phosphate measurements collected between 1925 and 2025, we quantify long‐term trends in nutrient concentrations across ocean biomes and depths.

Molecular Mechanisms of Algicidal Bacteria in Controlling Harmful Algal Blooms: Advances in Bacteria‐Algae Interactions

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 2, April 2026.
This review elucidates the molecular mechanisms of algicidal bacteria, highlighting critical behaviours like chemotaxis, quorum sensing and extracellular vesicle release. It details how these actions disrupt algal cellular integrity, photosynthesis and calcium homeostasis, providing a theoretical foundation for controlling harmful algal blooms ...

Clinical Practice Patterns in Bone Health Assessment and Management in Endogenous Cushing's Syndrome

open access: yesClinical Endocrinology, Volume 104, Issue 4, Page 302-311, April 2026.
ABSTRACT Objective Skeletal fragility is a common complication of endogenous Cushing's Syndrome (CS), although specific guidelines for managing bone health are lacking. This study aimed to assess clinicians' current engagement with bone health assessment and management in patients with endogenous CS. Design Retrospective‐cohort design. Patients Seventy‐

Surface wear and roughness of experimental composites containing calcium orthophosphate particles following toothbrush abrasion

open access: yesEuropean Journal of Oral Sciences, Volume 134, Issue 2, April 2026.
Abstract This study evaluated experimental composites containing dicalcium phosphate dihydrate (DCPD) particles for toothbrush wear and roughness. Composites containing bisphenol‐A glycidyl dimethacrylate/triethylene glycol dimethacrylate with 50 vol% inorganic fraction consisting of barium glass and DCPD (35:15 and 15:35 vol%) or barium glass only ...
