Rational Design of Hollow Structural Materials for Sodium-Ion Battery Anodes
Chem Rec. 2023 Sep 21:e202300206. doi: 10.1002/tcr.202300206. Online ahead of print.ABSTRACTThe development of sodium-ion battery (SIB) anodes is still hindered by their rapid capacity decay and poor rate capabilities. Although there have been some new materials that can be used to fabricate stable anodes, SIBs are still far from wide applications. Strategies like nanostructure construction and material modification have been used to prepare more robust SIB anodes. Among all the design strategies, the hollow structure design is a promising method in the development of advanced anode materials. In the past decade, research ...

Searching for bacteria able to metabolize polycyclic aromatic sulfur compounds in 12-years periodically fed bioreactor
This study aimed to identify microorganisms capable of degrading PASC in such environments. Among the 20 colonies isolated from an inoculum containing DBT as the sole sulfur source, only four isolates exhibited amplification of the dszA gene in the dszABC operon. The production of 2-hydroxybiphenyl (HPB) and a decrease in DBT were detected during the growth curve and resting cell assays. The isolates were identified using 16S rRNA sequencing belonging to the genera Stutzerimonas and Pseudomonas. These isolates demonstrated significant potential for biodesulfurization and/or degradation of PASC. All isolates possessed the p...

Impact of ecological stages on the soil microbiota and soil abiotic factors in tropical and subtropical Brazilian regions
Arch Microbiol. 2023 Sep 22;205(10):335. doi: 10.1007/s00203-023-03677-8.ABSTRACTOur aim was to test if ecological stages may influence the arbuscular mycorrhizal fungi (AMF), nematodes, and the soil chemical properties in agroforestry systems (AF), unassisted forest restoration (UFR), and natural ecosystem (Ne) located in the Brazilian Tropical and Subtropical regions. We collected soil samples to determine AMF, nematodes, soil pH, P, and soil organic carbon (SOC). AMF and nematode richness in the AF and Ne were similar in the tropical region. The redundancy analysis (RDA) indicated that the abundance of AMF and soil nema...

Oxidized galectin-1 in SLE fails to bind the inhibitory receptor VSTM1 and increases reactive oxygen species levels in neutrophils
Cell Mol Immunol. 2023 Sep 22. doi: 10.1038/s41423-023-01084-z. Online ahead of print.ABSTRACTInhibitory immune receptors set thresholds for immune cell activation, and their deficiency predisposes a person to autoimmune responses. However, the agonists of inhibitory immune receptors remain largely unknown, representing untapped sources of treatments for autoimmune diseases. Here, we show that V-set and transmembrane domain-containing 1 (VSTM1) is an inhibitory receptor and that its binding by the competent ligand soluble galectin-1 (Gal1) is essential for maintaining neutrophil viability mediated by downregulated reactive...

Plasticity of gastrointestinal vagal afferents in terms of feeding-related physiology and pathophysiology
J Physiol. 2023 Sep 22. doi: 10.1113/JP284075. Online ahead of print.ABSTRACTGastrointestinal vagal afferents play an important role in communicating food related information from the gut to the brain. This information initiates vago-vagal reflexes essential for gut functions, including gut motility and secretions. These afferents also play a role in energy homeostasis, signalling the arrival, amount and nutrient composition of a meal to the central nervous system where it is processed ultimately leading to termination of a meal. Vagal afferent responses to food related stimuli demonstrate a high degree of plasticity, resp...

Effects of Intra-Base Pair Proton Transfer on Dissociation and Singlet Oxygenation of 9-Methyl-8-Oxoguanine-1-Methyl-Cytosine Base-Pair Radical Cations
Chemphyschem. 2023 Sep 22:e202300511. doi: 10.1002/cphc.202300511. Online ahead of print.ABSTRACT8-Oxoguanosine is the most common oxidatively generated base damage and pairs with cytidine within duplex DNA. The 8-oxoguanosine-cytidine lesion, if not recognized and removed, not only leads to G-to-T transversion mutations but renders the base pair being more vulnerable to the ionizing radiation and singlet oxygen (1O2) damage. Herein, reaction dynamics of a prototype Watson-Crick base pair [9MOG·1MC]·+, consisting of 9-methyl-8-oxoguanine radical cation (9MOG·+) and 1-methylcystosine (1MC), was examined using mass spectr...

Analytical and preparative chiral supercritical fluid chromatography resolutions using crown ether-derived column
In this study, crown ether-derived column Crownpak® CR-I (+) was evaluated under SFC conditions using 12 primary amines, and the chromatographic results were compared against eight immobilized polysaccharide-based columns. Crownpak® CR-I (+) achieved a significantly higher success rate. It was found that the addition of 5% water to the modifier dramatically improved the peak shape for chiral separation of primary amines on Crownpak® CR-I (+). The first reported preparative SFC separations on Crownpak® CR-I (+) are shown, offering a new approach for the preparative resolution of primary amines. The case studies demonstr...

Rapid and Specific Detection of B. melitensis Targeting BMEI1661 Gene Using Loop-mediated Isothermal Amplification (LAMP) Combined With Lateral Flow immunoassay (LFIA)
Curr Microbiol. 2023 Sep 22;80(11):351. doi: 10.1007/s00284-023-03463-1.ABSTRACTB. melitensis is the most pathogenic zoonotic species of Brucella transmitted to animals through fetal secretions, placenta, and vaginal discharges of infected animals and humans by ingesting unpasteurized milk, dairy products, and raw meat. Early detection of B. melitensis is essential for timely intervention and control of the disease. The gold standard diagnostic methods, such as culture, are time-consuming and may take several weeks aiding to the disease spread. Loop-mediated isothermal amplification assay (LAMP) is widely used to detect in...

Identification and characterisation of a major outer membrane protein from Methylacidiphilum fumariolicum SolV
In this study, we identified and characterised a major outer membrane protein (WP_009059494) from Methylacidiphilum fumariolicum SolV. PRED-TMBB and AlphaFold2 predicted this protein to form a porin with a β-barrel structure consisting of ten antiparallel β-sheets and with a small amphipathic N-terminal α-helix in the periplasm. We purified soluble recombinant protein WP_009059494 from E. coli using Tris-HCl buffer with SDS. Antibodies were raised against two peptides in the two large extracellular loops of protein WP_009059494 and immunogold localisation showed this protein to be mainly present in the OM of strain SolV...
