Antimicrobial potential and alleviation of arsenic toxicity in human lymphocytes by bacterioruberin and selenium nanoparticles from Haloferax alexandrinus GUSF-1 (KF796625)

Discover Applied Sciences
Arsenic contamination is a significant environmental concern indirectly affecting human population. Application of haloarchaea and their biomolecules such as bacterioruberin (BR) and selenium nanoparticles (SeNPs) may play a role in alleviating arsenic ...

Halocins and C₅₀ Carotenoids from Haloarchaea: Potential Natural Tools against Cancer [PDF]

Marine Drugs
Haloarchaea are a group of moderate and extreme halophilic microorganisms, belonging to the Archaea domain, that constitute relevant microbial communities in salty environments like coastal and inland salted ponds, marshes, salty lagoons, etc.

Carotenoids from Halophilic Archaea: A Novel Approach to Improve Egg Quality and Cecal Microbiota in Laying Hens [PDF]

Animals
Carotenoids from different sources have different structures and functions, and their dietary components benefit the health of various organisms. The effects of halophilic Archaea-derived C50 carotenoids on poultry egg quality and gut microbiota remain ...

Life in the brine of Lunenburg, Germany: unveiling microorganisms associated with Zechstein salt deposits [PDF]

Frontiers in Microbiology
IntroductionThe presence of hypersaline brines on other planets and moons in the inner and outer Solar System has been well established. Hence, any theory of life on other planets must consider microorganisms adapted to high salt concentrations.

Bacterioruberin from <i>Haloferax mediterranei</i> Triggers Cytotoxic and Pro-Oxidant Effects in Different Solid Tumour Models, Effectively Targeting P-gp-Resistant Lung Cancer Cells. [PDF]

Int J Mol Sci
Bacterioruberin (BR), a C50 carotenoid produced by halophilic archaea, is emerging as a bioactive molecule with potential anticancer relevance, but its activity in solid tumour and multidrug-resistant (MDR) models remains poorly defined.

Inhalable nanocapsules for lung delivery of Pirfenidone and Bacterioruberin: Modulating macrophages to target pulmonary fibrosis

European Journal of Pharmaceutics and Biopharmaceutics
In this work, we developed an inhalable polymeric-lipid nanocapsule formulation with mucus-penetrating properties to co-encapsulate Pirfenidone (Pfd) and the carotenoid Bacterioruberin (BR), aiming to enhance anti-inflammatory, antioxidant, and antifibrotic effects by modulating pulmonary macrophage activity. Nanocapsules (pNC-BR-Pfd) were prepared via

The Role of Structural Order in the Mechanism of Charge Transport across Tunnel Junctions with Various Iron‐Storing Proteins

Small, Volume 18, Issue 42, October 20, 2022., 2022
Large proteins support remarkably high charge transport rates, but the factors that influence the charge transport mechanism are still unclear. This work shows the importance of structural order: ordered structures support coherent tunnelling pathways while charges “hop” across disordered structures.
