Refining techniques for high‐frequency monitoring of chlorophyll a fluorescence in estuarine systems

Limnology and Oceanography: Methods, EarlyView.
Abstract Concentrations of the photosynthetic pigment chlorophyll a are commonly used as a proxy for phytoplankton biomass in aquatic systems. Traditional methods for extracting chlorophyll a in discrete samples limit measurement frequency, while in situ sensor technology provides high frequency chlorophyll a fluorescence measurements at a more ...

From the sea to DNA barcode: Optimized preservation method for gelatinous zooplankton integrative taxonomy

Limnology and Oceanography: Methods, EarlyView.
Abstract Assigning taxonomic identity and thus assessing taxonomic diversity in gelatinous zooplankton is challenging due to their fragility and difficult preservation. Formalin fixation compromises DNA integrity, while flash‐freezing, ethanol, and acetone preservation affect morphological features. In this study, we developed a methodological protocol

Laparoscopic Methylene Blue Photodynamic Therapy for Intraabdominal Infection: A Preclinical Feasibility Study in a Rabbit Model of Perforated Appendicitis

Lasers in Surgery and Medicine, EarlyView.
ABSTRACT Objectives Perforated appendicitis commonly results in intra‐abdominal infection requiring prolonged antibiotic therapy. Intraoperative antimicrobial adjuncts are limited, and photodynamic therapy (PDT) may provide a targeted, resistance‐independent approach.

Species richness and intraspecific variation interactively shape marine diatom community functioning

Limnology and Oceanography Letters
Biodiversity generally increases productivity in ecosystems; however, this is mediated by the specific functional traits that come with biodiversity loss or gain and how these traits interact with environmental conditions.

The Use of Blue Light as an Antimicrobial Treatment Against Staphylococcus aureus: A Systematic Review

Lasers in Surgery and Medicine, EarlyView.
ABSTRACT Background Staphylococcus aureus (S. aureus) is a major cause of skin, wound, and device‐related infections. Blue light (405–470 nm), shows promise for treating this organism. However, the translatability, dosing parameters, safety, and effectiveness remain unclear, and no systematic review currently exists.

Advancing Therapies for Mycobacterial Diseases: From Small Molecules to Host‐Directed Strategies

Medicinal Research Reviews, EarlyView.
ABSTRACT The global burden of multidrug‐resistant tuberculosis (MDR‐TB) and the rising incidence of nontuberculous mycobacterial (NTM) infections highlight the urgent need for innovative therapeutic strategies. Current treatments are prolonged, toxic, and increasingly compromised by resistance and limited diagnostic capacity.

Spatiotemporal distribution patterns and assembly mechanisms of eukaryotic plankton communities in Liujiaxia Reservoir at the northeastern edge of the Tibetan Plateau

Microbiology Spectrum
Eukaryotic plankton are important parts of the aquatic ecosystem and their community composition and spatiotemporal distribution patterns are affected by environmental factors.

Drivers of stability in plankton communities: dominance, asynchrony, and averaging effects across temporal, spatial and trophic scales

Oikos, EarlyView.
The origins of ecosystem stability have long intrigued ecologists. Recent theoretical advancements highlight three primary mechanisms driving stability: dominance, asynchrony and averaging. While plant community stability has been extensively studied, our understanding of marine community stability remains limited. Plankton, as key components of marine
