Evaluation of Uliginosin B as a Modulator of the Ras Pathway: In Vivo Evidence From Caenorhabditis elegans and In Silico Insights

Chemistry &Biodiversity, Volume 23, Issue 8, August 2026.
This study performs in vivo and in silico assays with uliginosin B, targeting its activity in the Ras signaling pathway, demonstrating a possible allosteric interaction with the HRAS (human) and LET‐60 (nematode) proteins, and a decrease in the overexpression of the let‐60 gene in the nematode C. elegans.

Environmental and local habitat variables as predictors of trophic interactions in subtidal rocky reefs along the SE Pacific coast

Ecography, Volume 2026, Issue 8, August 2026.
Temperature generally drives latitudinal patterns in the strength of trophic interactions, including consumption rates. However, local community and other environmental conditions might also affect consumption, disrupting latitudinal gradients, which results in complex large‐scale patterns.

The Suppressive Activity of Fucofuroeckol-A Derived from Brown Algal Ecklonia stolonifera Okamura on UVB-Induced Mast Cell Degranulation

Marine Drugs, 2018
UV light, especially UVB, is known as a trigger of allergic reaction, leading to mast cell degranulation and histamine release. In this study, phlorotannin Fucofuroeckol-A (F-A) derived from brown algal Ecklonia stolonifera Okamura was evaluated for its ...

Advances in Pharmacological Therapy of Benign Tracheal Stenosis: A Meta‐Analysis of Preclinical Studies

Laryngoscope Investigative Otolaryngology, Volume 11, Issue 4, August 2026.
ABSTRACT Background Benign tracheal stenosis, characterized by granulation hyperplasia, is a rare and serious disease threatening human health. Interventional bronchoscopy demonstrates limited therapeutic efficacy and poses a risk of re‐injury to the airway.

Standardized 16S Meta‐Analysis Reveals Consistent Host‐Associated Patterns in Laminariales Epiphytic Microbiomes

MicrobiologyOpen, Volume 15, Issue 4, August 2026.
An integrated bioinformatic pipeline combining taxonomic, functional, and network analyses revealed host‐driven structuring of macroalgal microbiomes. Phaeophyceae hosted distinct epiphytic communities enriched in chemoheterotrophy and polysaccharide degradation, highlighting metabolic coupling, keystone taxa, and a standardized framework for ...

Holdfast adhesion in the kelp Alaria marginata: Cell wall polysaccharides and phenolics

Journal of Phycology, Volume 62, Issue 4, Page 1344-1355, August 2026.
Abstract Adhesion is a critical process in the survival of seaweeds, especially in wave‐swept environments. Kelp (Laminariales) sporophytes secrete adhesives from specialized rhizoid cells to anchor themselves to the substrate and withstand immense forces applied by waves.

Diversity of phlorotannin profiles among sargassasacean species affecting variation and abundance of epiphytes

, 2016
In general, epiphytes have detrimental effects on the growth of their basiphytes due to competition for light and nutrients. Therefore, basiphyte species must expend energy suppressing epiphytes. Some studies suggest that phlorotannins, i.e.
