Ocean acidification at the crossroads I: Harmonizing unpurified and purified meta‐cresol purple spectrophotometric pHT measurements based on absorbance data

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Consistent monitoring of seawater spectrophotometric pH on the total hydrogen ion scale (pHT) has been questioned by an evolving method, with changes in parameterization and the purity of the meta‐cresol purple (mCP). Using real seawater samples, we demonstrate that spectrophotometric pHT measurements obtained with unpurified (UNPUR) and ...

Bioengineered Bacterial Vesicles and Biomimetic Hybrids Eliminate Biofilms and Balance the Gut Microbiome

open access: yesSmall, EarlyView.
Biomimetic nanocarriers based on liposomes and Myxobacteria outer‐membrane vesicles (OMVs) are effective antibiotic delivery systems. Hybrids have a higher drug loading and can target intracellular pathogens, while OMVs evade immune clearance. Biomimetic nanoantibiotics effectively eliminate the biofilms of Gram‐negative bacteria. Besides, Myxobacteria

Organelle Sorting and Proteomic Analysis to Identify Proteins Involved in the Uptake and Intracellular Trafficking of Nanoparticles

open access: yesSmall Methods, EarlyView.
A new method to identify proteins involved in the uptake and intracellular trafficking of nanoparticles is presented. After nanoparticle uptake, cells are lysed and the organelles with nanoparticles are purified using fluorescence assisted cell sorting. Next, their composition is determined by proteomic analysis.

Can Fecal T3 Metabolite Level Fluctuations in European Roe Deer (Capreolus capreolus) Give Insights on Body Condition and Thermal Stress?

open access: yesIntegrative Zoology, EarlyView.
European roe deer fecal samples were assayed to investigate the potential fluctuations of fecal thyroid hormone metabolites (FTMs) in response to environmental (e.g., the temperature, local densities) and individual (e.g., sex, age, body, and nutritional conditions) variables.
