Emergence of Staphylococcus aureus Resistance to Antimicrobial Peptides Nisin, NZ2114 and Bacitracin Involves Multiple Phenotypic Changes

open access: yesAnimal Research and One Health, EarlyView.
The AMP‐induced mutant Staphylococcus aureus strain nzR showed increased resistance, five gene mutations, and decreased surface anion levels. AMPs affect the NDH‐2 protein encoded by ndh gene inhibiting the growth of S. aureus. The deletion of the ndh gene promotes the development of AMPs resistance.

The effect of sodium nitroprusside in scaffolds for synergetic gas‐photothermal therapy of osteosarcoma

open access: yesBMEMat, EarlyView.
The PCLA‐SNP scaffolds can produce photothermal agents in situ under ultraviolet radiation. Then, the scaffold can release nitric oxide gas spontaneously and generate hyperthermia under near‐infrared laser to enhance ablation of bone tumors. Furthermore, the calcium and iron ions released from PCLA‐SNP scaffolds can accelerate bone regeneration ...

Simvastatin overcomes the pPCK1‐pLDHA‐SPRINGlac axis‐mediated ferroptosis and chemo‐immunotherapy resistance in AKT‐hyperactivated intrahepatic cholangiocarcinoma

open access: yesCancer Communications, EarlyView.
Abstract Background Intrahepatic cholangiocarcinoma (ICC) is a challenging cancer with an increasing incidence. The Phase III TOPAZ‐1/KEYNOTE‐966 study demonstrated chemo‐immunotherapy (CIT) as a significant advancement, potentially replacing traditional chemotherapy for advanced biliary tract cancer.

Cytotoxic Activity of Opopanax hispidus (Friv.) Griseb.: Characterization of a New Chalcone‐type Compound

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT The present study aimed to investigate cytotoxic compounds of Opopanax hispidus (Friv.) Griseb. through in vitro, in silico, and phytochemical analyses. The cytotoxic activity of O. hispidus was evaluated against four different cancer cell lines – lung (A549), breast (MCF‐7), liver (HepG2), and cervix (HeLa) – as well as one healthy cell line (

Boosting Antibiotic Efficacy of Azole Drugs against Methicillin‐Resistant Staphylococcus Aureus by Coordination to Rhenium Carbonyl Complexes

open access: yesChemBioChem, EarlyView.
Coordination of antifungal azoles to rhenium di‐ and tricarbonyl complexes results in compounds with enhanced antimicrobial efficacy—up to 32‐fold minimum inhibitory concentration improvement—against methicillin‐sensitive and methicillin‐resistant Staphylococcus aureus over parent azoles.

Myocardial inflammation is associated with impaired mitochondrial oxidative capacity in ischaemic cardiomyopathy

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1246-1255, April 2025.
Abstract Aims Myocardial inflammation and impaired mitochondrial oxidative capacity are hallmarks of heart failure (HF) pathophysiology. The extent of myocardial inflammation in patients suffering from ischaemic cardiomyopathy (ICM) or dilated cardiomyopathy (DCM) and its association with mitochondrial energy metabolism are unknown.

Inconsistent Transcriptomic Responses to Hexabromocyclododecane in Japanese Quail: A Comparative Analysis of Results From Four Different Study Designs

open access: yesEnvironmental Toxicology and Chemistry, EarlyView.
Abstract Efforts to use transcriptomics for toxicity testing have classically relied on the assumption that chemicals consistently produce characteristic transcriptomic signatures that are reflective of their mechanism of action. However, the degree to which transcriptomic responses are conserved across different test methodologies has seldom been ...
