Membrane Proteins as Maxwell’s Demons and Their Significance for P Systems [PDF]

, 2008
The aim of these notes is to contribute to the dialog between P systems and Biological Sciences focussing on membrane proteins involved either in iron transport inside the bacterial cells or in elimination outside the bacterial cells of substances ...

Magnetic irreversibility and Verwey transition in nano-crystalline bacterial magnetite [PDF]

, 2007
The magnetic properties of biologically-produced magnetite nanocrystals biomineralized by four different magnetotactic bacteria were compared to those of synthetic magnetite nanocrystals and large, high quality single crystals.

A Comprehensive Study of Biohopanoid Production in Alphaproteobacteria: Biosynthetic, Chemotaxonomical, and Geobiological Implications

Geobiology, Volume 23, Issue 6, November/December 2025.
ABSTRACT Bacteriohopanepolyol derivatives (BHPDs) and dia‐ and catagenetic products formed from these bacterial membrane modifiers are extensively used as biomarkers in molecular ecological and geoscience studies. Some BHPDs can be assigned to specific phylogenetic bacterial groups. With the vastly increasing availability of complete bacterial genomes,

Magnetosomes - Bacterial Magnetic Nanoparticles

Communications, 2014
The magnetic properties, magneto-optical effects and hyperthermia effect were studied in solution of magnetosomes extracted from cultivated bacteria Magnetospirillum sp. AMB-1. The properties of magnetosomes were changed using different conditions during

Synthesis of the bacterial magnetosome: the making of a magnetic personality [PDF]

, 2010
Magnetotactic bacteria synthesize intracellular, enveloped, single magnetic domain crystals of magnetite Fe3O4, Fe2+Fe23+O4) and/or greigite (Fe3S4) called magnetosomes.

Multivariate Screening and Automated Clustering of Macrophage Immunoreactome to Nanoparticles and Photothermal Therapy

Advanced Science, Volume 12, Issue 31, August 21, 2025.
Predicting immune responses to treatments, including nanomedicines, with high throughput test is challenging due to the immunoreactome's complexity and plasticity. A predictive screening platform integrating pathway activation and gene profiling in macrophages has been developed as a versatile tool for designing effective immunotherapies.

Isolation, Characterization and Kinetics of Perchlorate ReducingMagnetospirillumSpecies

Geomicrobiology Journal, 2017
Perchlorate reducing bacteria reduce perchlorate to chlorate (ClO3−), which, in turn, is reduced to chlorite (ClO2−) and ultimately to chloride (Cl−). Magnetospirillum strains are reported to use chlorate/perchlorate as electron acceptors. This study describes the perchlorate reducing property of strain VITRJS5, a Magnetopsirillum isolated from ...

The biomineralization of magnetosomes in Magnetospirillum gryphiswaldense [PDF]

, 2010
Magnetotactic bacteria (MTB) are major constituents of natural microbial communities in sediments and chemically stratified water columns. The ability of MTB to migrate along magnetic field lines is based on specific intracellular structures, the ...

A genome phylogeny for mitochondria among alpha-proteobacteria and a predominantly eubacterial ancestry of yeast nuclear genes [PDF]

, 2004
Analyses of 55 individual and 31 concatenated protein data sets encoded in Reclinomonas americana and Marchantia polymorpha mitochondrial genomes revealed that current methods for constructing phylogenetic trees are insufficiently sensitive (or artifact ...

Micro‐ and nanomotors in biomedical applications

Responsive Materials, Volume 3, Issue 3, August 2025.
Micro‐ and nanomotors (MNMs), as autonomous devices converting chemical or external energy into mechanical propulsion, have emerged as transformative drug delivery platforms in biomedicine. This review systematically outlines the design principles governing MNMs' propulsion and operation, highlights the applications of MNMs in disease treatment, and ...
