Rapid Determination of Chemical Oxygen Demand (COD) Using Focused Microwave Digestion Followed by a Titrimetric Method

open access: yesAnalytical Sciences, 2001
water-pollution control analysis. It is closely related to the organic contamination level of a water or wastewater sample. The Cr-COD method is used as the standard in USA and Taiwan. Compared to Japanese Mn-COD method, it has a higher detection limit and severe chloride ion interference because of the stronger oxidant and the longer digestion time ...

The C‐terminal domain of yeast Arginyltransferase1 is essential for its catalytic activity

open access: yesFEBS Open Bio, EarlyView.
Arginyltransferase 1 (Ate1), a eukaryotic enzyme, catalyses arginylation, transferring arginine from tRNA‐Arg to the amino terminus of the target protein. Overexpression of Ate1 in yeast is lethal and is dependent on arginylation. This study elucidates how mutations in the cofactor‐binding and active site of Ate1 and truncation of its structural ...

MARK4 enhances stress granule formation under oxidative stress and increases tau accumulation

open access: yesFEBS Open Bio, EarlyView.
MARK4 (red dots) localizes to stress granules (orange dots) and promotes their formation under oxidative stress by modulating TIA1 (blue dots). MARK4 and TIA1 synergistically increase tau (purple) accumulation, and the reduction of the TIA1 ortholog suppresses neurodegeneration in a fly model.

Bioremediation of synthetic dairy effluent using microalgae for biomass production and the removal of organic pollution load [PDF]

open access: yesE3S Web of Conferences
Dairy wastewater is distinguished by higher BOD and COD levels, as well as substantial amounts of dissolved or suspended solids such as fats, oils, and grease, nutrients such as ammonia or minerals and phosphates, and so demonstrates the significance of ...

Identification and characterization of a gene conferring stress resistance in Escherichia coli and cyanobacteria

open access: yesFEBS Open Bio, EarlyView.
Functional screening identified PcSyn14890, a cyanobacteria‐specific protein that enhances growth and stress resistance in E. coli and Synechocystis PCC6803. Although we expected it to function as a molecular chaperone, it was unable to protect against thermal aggregation of GAPDH.

Seasonal Dynamics and Interconnected Physico-Chemical and Biological Water Quality Parameters in the Muari River, West Papua Province, Indonesia [PDF]

open access: yesBIO Web of Conferences
Understanding seasonal dynamics in tropical rivers is crucial to link land use, geomorphology, and ecosystem health. This study examined the seasonal dynamics and interconnections among physico-chemical, sediment, and biological parameters in the Muari ...

Selective elimination of quiescent cancer cells by dequalinium chloride via ROS‐mediated ferroptosis

open access: yesFEBS Open Bio, EarlyView.
Dequalinium chloride (DQ) selectively eliminates quiescent cancer cells (QCCs) by amplifying mitochondrial ROS. QCCs exhibit elevated basal ROS and limited redox‐buffering capacity, making them vulnerable to further ROS increases. DQ‐induced ROS exceeds the tolerance threshold, triggering lipid peroxidation and ferroptosis, whereas proliferating cells ...

TRPML1 agonist ML‐SA5 attenuates pulmonary fibroblast activation by suppressing mTOR and restoring autophagic flux

open access: yesFEBS Open Bio, EarlyView.
TGF‐β1 stimulation downregulates lysosomal channel TRPML1 in pulmonary fibroblasts. The TRPML1 agonist ML‐SA5 suppressed fibroblast‐to‐myofibroblast activation and collagen production. Mechanistically, ML‐SA5 inhibited mTOR phosphorylation, restored autophagic flux, and its effects were enhanced by rapamycin (mTOR inhibitor) and reversed by MHY1485 ...

Fluorination: A strategy to tune the interactions of molecules and nanoscale systems with biological matter

open access: yesFEBS Open Bio, EarlyView.
This minireview explores fluorination as a key strategy to optimize therapeutic molecules and nanocarriers. By incorporating different fluorinated motifs—from single atoms to linear and branched chains—drug delivery, cellular uptake, and colloidal stability can be improved and fine‐tuned.
