State of Manganese in Manganese Oxides [PDF]

Nature, 1949
CHEMICAL estimation of trivalent manganese has been possible using a stable complex ion formed with acetylacetone. This complex is formed from solutions of red manganic sulphate and also when γ-Mn2O3 is dissolved in concentrated hydrochloric acid in the presence of acetylacetone.

Electrodeposition of Manganese Metal and Co-production of Electrolytic Manganese Dioxide Using Single-membrane Double-chamber Electrolysis

Electrochemistry, 2021
Given the problems of high energy consumption, low resource utilization, and severe environmental pollution in traditional electrolytic manganese or manganese dioxide, this study puts forth a single-membrane double-chamber electrolysis method for the ...

Pathways of methane removal in the sediment and water column of a seasonally anoxic eutrophic marine basin

Frontiers in Marine Science, 2023
Methane (CH4) is a key greenhouse gas. Coastal areas account for a major proportion of marine CH4 emissions. Eutrophication and associated bottom water hypoxia enhance CH4 production in coastal sediments.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

FEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Is a Combination of Metals More Toxic to Mosses Than a Single Metal?

Plants, 2023
Increasing pollution in the environment calls for the precise determination of metal toxicity in plants as they are at the base of the food chain. Mosses are often employed as biomonitors and provide good models for testing metal adsorption.

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

Molecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

Molecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...
