Wireless In Situ Catalytic Electron Signaling‐Mediated Transcriptomic Reprogramming for Neuron Regeneration via Adaptable Antennas

open access: yesAdvanced Science, EarlyView.
A wireless‐charging sustained oxygen release from conductive microgels (SOCO) served as an antenna and an on‐demand O2 release for nerve regeneration is developed. Introducing “electromagnetic messenger”, using external alternating magnetic field (AMF) to enhance catalytic oxygen release and electrical stimulation to promote the reconstruction of blood

Sugar-binding and split domain combinations in repeats-in-toxin adhesins from Vibrio cholerae and Aeromonas veronii mediate cell-surface recognition and hemolytic activities

open access: yesmBio
Many pathogenic Gram-negative bacteria use repeats-in-toxin adhesins for colonization and biofilm formation. In the cholera agent Vibrio cholerae, flagellar-regulated hemagglutinin A (FrhA) enables these functions.

Fc-Galactosylation of Human Immunoglobulin Gamma Isotypes Improves C1q Binding and Enhances Complement-Dependent Cytotoxicity

open access: yesFrontiers in Immunology, 2017
Binding of the complement component C1q to the CH2 domain of antigen-bound immunoglobulin gamma (IgG) activates the classical complement pathway and depends on its close proximity to Fc fragments of neighboring antibodies. IgG subclasses contain a highly

Impact of Virus‐Mediated Modifications in Bacterial Communities on the Accumulation of Soil Organic Carbon

open access: yesAdvanced Science, EarlyView.
This study illustrates the impact of viruses on carbon cycling in soils with different availabilities of carbon. In conditions of low carbon availability, viruses adopt a lysogenic lifestyle, integrate into the host genomes and facilitate the degradation of carbon.

Inter-individual and inter-regional variability of breast milk antibody reactivity to bacterial lipopolysaccharides

open access: yesFrontiers in Immunology
Breast milk is a vital source of nutrients, prebiotics, probiotics, and protective factors, including antibodies, immune cells and antimicrobial proteins. Using bacterial lipopolysaccharide arrays, we investigated the reactivity and specificity of breast

Diatom-Specific Oligosaccharide and Polysaccharide Structures Help to Unravel Biosynthetic Capabilities in Diatoms

open access: yesMarine Drugs, 2015
Diatoms are marine organisms that represent one of the most important sources of biomass in the ocean, accounting for about 40% of marine primary production, and in the biosphere, contributing up to 20% of global CO2 fixation.

GlycanML: A Multi-Task and Multi-Structure Benchmark for Glycan Machine Learning [PDF]

open access: yesarXiv
Glycans are basic biomolecules and perform essential functions within living organisms. The rapid increase of functional glycan data provides a good opportunity for machine learning solutions to glycan understanding. However, there still lacks a standard machine learning benchmark for glycan property and function prediction.

Nanosurgery: Observation of Peptidoglycan Strands in Lactobacillus helveticus Cell Walls [PDF]

open access: yesarXiv, 2004
The internal cell wall structure of the bacterium Lactobacillus helveticus has been observed in situ in aqueous solution using an atomic force microscope (AFM). The AFM tip was used not only for imaging but presumably to remove mechanically large patches of the outer cell wall after appropriate chemical treatment, which typically leaves the bacteria ...

4,6‐O‐Phenylboronic Ester Protection for 1,2‐cis‐α‐Selective Glucosylation

open access: yesAsian Journal of Organic Chemistry, EarlyView.
The 4,6‐O‐phenylboronic ester protection for 1,2‐cis‐α‐selective glucosylation, previously reported by the Crich group, was revisited and the stereodirecting effect of the cyclic protecting group was unveiled. 4,6‐O‐Phenylboronic ester‐protected glucosyl and 2‐azido‐2‐deoxyglucosyl donors exhibited higher α‐selectivity of the glucosylation than the ...
