The Effect of Variations in Temperature and Contact Time of Zingerone, [6]-Gingerol and Shogaol as Disinfectants on Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Candida albicans

Microorganisms
Rising microbial resistance to synthetic disinfectants has intensified the search for chemically synthesized natural alternatives, such as ginger-derived bioactive compounds. Several bioactive compounds, including Zingerone, Gingerols, and Shogaols, have

Glucocorticoid Receptor Signaling in Myeloid Cells Orchestrates Inflammation Resolution and Muscle Repair

Advanced Science, EarlyView.
Glucocorticoids (GC) are widely used to reduce inflammation. We show that the glucocorticoid receptor in myeloid cells regulates macrophage cell cycle and genome integrity during muscle regeneration. We demonstrate that dexamethasone administration during the early inflammatory phase delays muscle repair by increasing macrophage proliferation ...

Protamine-induced permeabilization of cell envelopes of gram-positive and gram-negative bacteria

, 1997
The inhibitory effect of the cationic peptide protamine on Listeria monocytogenes, Escherichia coli, and Shewanella putrefaciens has been studied in detail, The addition of protamine (10 to 1,000 mu g/ml) resulted in inhibition of oxygen consumption ...

An Injectable, Self‐Expanding Hemostatic Foam for Field‐Compatible Postpartum Hemorrhage Management

Advanced Science, EarlyView.
Postpartum hemorrhage is the leading cause of maternal death worldwide, yet many treatments are hard to use outside well‐equipped hospitals. This work introduces an easy‐to‐use device that rapidly delivers a degradable foam into the uterus. The foam stops bleeding through pressure and clotting support, offering a practical option for low‐resource ...

Helicobacter pylori‐Induced Persistent IGF2BP1 Activation Promotes Ferroptosis Resistance in Gastric Tumorigenesis

Advanced Science, EarlyView.
Helicobacter pylori infection induces sustained upregulation of the RNA‐binding protein IGF2BP1 in gastric epithelial cells, establishing a persistent epitranscriptomic program. IGF2BP1 stabilizes SLC7A11 mRNA in an m6A‐dependent manner to suppress ferroptosis and promote epithelial survival under oxidative stress. Pharmacological inhibition of IGF2BP1

Synthetic Shewanella‐Bacillus Microbial Consortia for Enhanced Metal Oxide Leaching From Spent Lithium‐Ion Batteries Using Brewing Wastewater as Leaching Agent

Advanced Science, EarlyView.
A recycling approach of spent lithium‐ion batteries is developed using brewing wastewater as the leaching agent and an engineering microbial consortium as the biocatalyst. Shewanella oneidensis reduces spent LiNixCoyMn1‐x‐yO2 cathodes via extracellular electron transfer, while Bacillus subtilis removes residual ethanol to eliminate inhibition.

Targeting the YAP‐BST2 Axis Overcomes Intrinsic Anti‐PD‐1 Resistance in Metastatic Gastric Cancer

Advanced Science, EarlyView.
Concurrent YAP hyperactivation and Tp53 loss in Atp4b‐expressed parietal cell lineage drives gastric cancer initiation, multi‐organ metastasis, and intrinsic resistance to anti‐PD‐1 therapy. BST2 emerges as a direct YAP‐TEAD transcriptional target that engages PIRA2 on myeloid cells to establish an immunosuppressive microenvironment.
