Mechanisms of Mitochondrial Toxicity and Cytotoxicity Caused by Pseudomonas aeruginosa Pyocyanin in Human Nasal Epithelial Cells

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Pseudomonas aeruginosa is an opportunistic pathogen in cystic fibrosis‐related chronic rhinosinusitis (CF‐CRS) that produces phenazine metabolites pyocyanin and 1‐hydroxyphenazine (1‐HP), which may have detrimental effects on mitochondria, reactive oxygen species (ROS), Ca2+ signaling, and apoptosis.

Optimization and verification of high‐fat diet formulation for establishing a rat model of obesity‐related precocious puberty

Animal Models and Experimental Medicine, EarlyView.
We identified 45% HFD as the optimal formulation to establish a juvenile rat model of obesity‐related precocious puberty. It elicits robust phenotypic (early vaginal opening, obesity), histological (advanced ovarian development), and endocrine (elevated HPG axis hormones) alterations, with leptin‐mediated GnRH secretion as a core mechanistic driver ...

Sex as a biological variable in nonclinical studies: Bridging scientific rigor, animal welfare, and regulatory expectations

Animal Models and Experimental Medicine, EarlyView.
Sex as a biological variable (SABV) is a critical determinant of pharmacokinetics, pharmacodynamics, and toxicity in nonclinical studies. This review highlights how inappropriate neglect of sex differences compromises animal welfare, scientific reproducibility, and regulatory compliance.

Nanomaterial‐Mediated Near‐Infrared Photothermal Neuromodulation for Neurologic Disorders

Advanced NanoBiomed Research, EarlyView.
This review summarizes how near‐infrared light activates photothermal nanomaterials to enable noninvasive neuromodulation with high spatiotemporal precision. It elucidates the underlying mechanisms, explores targeted therapeutic applications for neurological disorders, discusses integration with optogenetics and biosensors, and addresses future ...

Controlled Delivery and Light‐Induced Release of Magic Spot Nucleotides in Escherichia coli

Angewandte Chemie International Edition, EarlyView.
We synthesized photocaged, clickable and isotope‐labeled “magic spot” Nucleotides and delivered them into Escherichia coli comparing different approaches. Light‐controlled release inside living cells enabled tracking of their conversion from pppGpp to ppGpp by capillary electrophoresis mass spectrometry and revealed their impact on the growth rate of a
