Reprogramming of gene expression in Escherichia coli cultured on pyruvate versus glucose
(Springer, 2019-07-30)
Previous studies revealed important roles of small RNAs (sRNAs) in regulation of bacterial metabolism, stress responses and virulence. However, only a minor fraction of sRNAs is well characterized with respect to the spectra ...
Clinical factors associated with a Candida albicans Germ Tube Antibody positive test in Intensive Care Unit patients
(BioMed Central, 2011-03)
Background: Poor outcomes of invasive candidiasis (IC) are associated with the difficulty in establishing the microbiological diagnosis at an early stage. New scores and laboratory tests have been developed in order to ...
Composition and conservation of the mRNA-degrading machinery in bacteria
(BioMed Central, 2011)
RNA synthesis and decay counteract each other and therefore inversely regulate gene expression in pro- and eukaryotic cells by controlling the steady-state level of individual transcripts. Genetic and biochemical data ...
Prokaryotic Capability to Use Organic Substrates Across the Global Tropical and Subtropical Ocean
(Frontiers Media, 2020)
Prokaryotes play a fundamental role in decomposing organic matter in the ocean, but little is known about how microbial metabolic capabilities vary at the global ocean scale and what are the drivers causing this variation. ...
Graphene Oxide–Silver Nanoparticle Nanohybrids: Synthesis, Characterization, and Antimicrobial Properties
(MDPÎ, 2020-02-21)
Drug resistance of pathogenic microorganisms has become a global public health problem, which has prompted the development of new materials with antimicrobial properties. In this context, antimicrobial nanohybrids are an ...
Regulation of Energy Metabolism by the Extracytoplasmic Function (ECF) σ Factors of Arcobacter butzleri
(Public Library of Science, 2012-09-18)
The extracytoplasmic function (ECF) σ factors are fundamental for bacterial adaptation to distinct environments and for survival under different stress conditions. The emerging pathogen Arcobacter butzleri possesses seven ...
Isolation of Cancer-Derived Exosomes Using a Variety of Magnetic Nanostructures: From Fe3O4 Nanoparticles to Ni Nanowires
(MDPI, 2020-08-25)
Isolating and analyzing tumor-derived exosomes (TEX) can provide important information about the state of a tumor, facilitating early diagnosis and prognosis. Since current isolation methods are mostly laborious and ...

Elucidating the role of shape anisotropy infaceted magnetic nanoparticles using biogenicmagnetosomes as a model
(Royal Society of Chemistry, 2020-08-14)
Shape anisotropy is of primary importance to understand the magnetic behavior of nanoparticles, but a rigorous analysis in polyhedral morphologies is missing. In this work, a model based on finite element techniques has ...
Magnetosomes could be protective shields against metal stress in magnetotactic bacteria
(Nature, 2020-07)
Magnetotactic bacteria are aquatic microorganisms with the ability to biomineralise membrane-enclosed magnetic nanoparticles, called magnetosomes. These magnetosomes are arranged into a chain that behaves as a magnetic ...
