Iron‐dependent lysosomal LDL oxidation induces the expression of scavenger receptor A in human THP‐1 monocytes

open access: yesFEBS Open Bio, EarlyView.
In human monocytic cells THP‐1, a limited uptake of native—not oxidized—LDL/VLDL induced expression of scavenger receptor A and cellular adhesion. Induction was inhibited by lysosomotropic (WR‐1065) and lipophilic (BHT) antioxidants and by siRNAs against ferritinophagy.

Characteristics of gasoline flash boiling atomization triggered by iso-pentane blends at different ratio

open access: yesCase Studies in Thermal Engineering, 2023
Flash boiling spray can improve fuel atomization efficiency via fierce phase change of the fuels both inside and outside the nozzle. Typically, active flash boiling atomization is achieved by heating the fuel before injection, which would require ...

Thermodynamic Analysis of Ozone-Safe Low Boiling Working Media for Turbo-Expander Plants

open access: yesИзвестия высших учебных заведений и энергетических объединенний СНГ: Энергетика, 2020
The article considers 46 low-boiling working media (LBWM) with zero potential for ozone layer destruction. Out of them, 14 ones are single-component hydrofluorocarbon refrigerants, 28 ones are multi-component mixtures of hydrofluorocarbon refrigerants ...

The impact of frailty syndrome on skeletal muscle histology: preventive effects of exercise

open access: yesFEBS Open Bio, EarlyView.
Frailty syndrome exacerbates skeletal muscle degeneration via increased ECM deposition and myofiber loss. This study, using a murine model, demonstrates that endurance exercise attenuates these histopathological alterations, preserving muscle integrity. Findings support exercise as a viable strategy to counteract frailty‐induced musculoskeletal decline

Short peptide perturbs spermatogenesis via immune microenvironment dysregulation and mitochondrial imbalance

open access: yesFEBS Open Bio, EarlyView.
In the blood–testis barrier, occludin is crucial for tight junctions. This study demonstrates that occludin‐targeting short peptides disrupt junction integrity, inducing immune cell infiltration, tumor necrosis factor‐α/interleukin‐6 secretion and mitochondrial dysfunction, ultimately triggering apoptosis.

Analysis of the regulation of undecaprenyl diphosphate dephosphorylation in Escherichia coli

open access: yesFEBS Open Bio, EarlyView.
BacA, PgpB, and YbjG phosphatases are involved in undecaprenyl phosphate (C55P) synthesis in Escherichia coli. We analyzed the lipid contents and the gene expression in the gene‐disruption strains. Undecaprenyl diphosphate (C55PP) level increased in the bacA, ybjG double‐disruption strain, but C55P levels were similar in all strains.

Purification of artemisinin precursor amorphadiene from microbial metabolites containing isomeride farnesene: Solid-Pd chemocatalysis of farnesene to squalene with high boiling point

open access: yesCatalysis Communications, 2023
Due to complex chemical mechanism of sesquiterpene synthases, amorpha-4, 11-diene (AD) from microbial fermentation contained isomeride β-farnesene (FA) with similar boiling point.
