Novel Magnetic MnFeO-Decorated Graphite-Like Porous Biochar as a Heterogeneous Catalyst for Activation of Peroxydisulfate Toward Degradation of Rhodamine B.

A magnetic MnFeO-modified graphite-like porous biochar composite (MnFeO/KFS800) was synthesized by the hydrothermal method, and its catalytic activity was evaluated in the activation of peroxydisulfate toward degradation of Rhodamine B. After characterization by SEM, XRD, and the BET method, the specific surface area and total pore volume of the MnFeO/KFS800 catalyst reached 121 m/g and 0.263 m/g, and exhibited plate-like morphology with good crystallinity.

Cochlear transcript diversity and its role in auditory functions implied by an otoferlin short isoform.

Isoforms of a gene may contribute to diverse biological functions. In the cochlea, the repertoire of alternative isoforms remains unexplored. We integrated single-cell short-read and long-read RNA sequencing techniques and identified 236,012 transcripts, 126,612 of which were unannotated in the GENCODE database.

Preparation of Gold Nanoplates Using Ortho Carbonyl Compounds as Capping Agents for Electrochemical Sensing of Lead Ions.

In this study, gold nanoplates were synthesized using plant molecules (gallic acid) following a kinetic control mode. The growth of nanoplates is mainly due to the specific adsorption of capping agents on certain crystal facets. Through systematical characterizations, it is found that the distance between two oxygen atoms in ortho carbonyl compounds matches well with the lattice spacing of gold (111) facets exactly, which is beneficial to the formation of twin seeds and further the growth of plate-like gold nanoparticles.

TAOK1 positively regulates TLR4-induced inflammatory responses by promoting ERK1/2 activation in macrophages.

Thousand and one amino acid kinase 1 (TAOK1) is a member of Ste20-like kinases, but its function in regulating inflammatory responses remains largely unknown. In this study, we identify TAOK1 as a positive regulator of TLR4-triggered inflammatory responses in macrophages. TAOK1 increases LPS-induced production of pro-inflammatory cytokine such as IL-6, TNF-α and IL12p40 in macrophages.

The Diversity of the Endobiotic Bacterial Communities in the Four Jellyfish Species.

The associated microbiota plays an essential role in the life process of jellyfish. The endobiotic bacterial communities from four common jellyfish , and were comparatively analyzed by 16S rDNA sequencing in this study. Several 1049 OTUs were harvested from a total of 130 183 reads.

An integrated transcriptomic and proteomic analysis reveals toxin arsenal of a novel Antarctic jellyfish Cyanea sp.

Jellyfish is a common toxic zooplankton in ocean. We successfully captured a kind of jellyfish 200 m underwater in Antarctica, and identified it as a jellyfish Cyanea sp. through morphological examination and MT-CO1 phylogenetic analysis.

Stress-Induced Mucus Secretion and Its Composition by a Combination of Proteomics and Metabolomics of the Jellyfish .

Background: Jellyfish respond quickly to external stress that stimulates mucus secretion as a defense. Neither the composition of secreted mucus nor the process of secretion are well understood.

Methods: jellyfish were stimulated by removing them from environmental seawater.

De novo transcriptomic analysis of the venomous glands from the scorpion Heterometrus spinifer revealed unique and extremely high diversity of the venom peptides.

Scorpion, as an ancient species, has been widely used on dozens of human diseases in traditional Chinese Medicine. Although the scorpion venom from the Buthidae family with the potent toxicity attracts more interests, toxins from the non-Buthidae family draw great attention as well because of its abundance and complexity even without harm to mammals. Moreover, several toxic components of scorpion venom have been identified as valuable scaffolds for the drug design and development.
