Reversing Temozolomide Resistance in Glioblastoma Based on Cuproptosis‐Mediated Positive Feedback Loop

Advanced Science, EarlyView.
To effectively reverse TMZ resistance, this work proposes a cuproptosis‐mediated positive feedback loop that integrates mitochondrial dysfunction, ATP depletion, AMPK‐p53 signaling, and glycolytic inhibition, ultimately amplifying cell death. This cuproptosis‐mediated feedback loop simultaneously disrupts multiple resistance pathways in GBM, including ...

Harmonizing Rigidity and Flexibility: Embedding COF Quantum Dots Into Extracellular Matrix Gel as Carbon Monoxide Depot for Acoustically Triggered Time‐Programmable Anti‐Infective Therapy

Advanced Science, EarlyView.
A rigid‑flexible integrated CO depot is engineered by embedding rigid COFQDs into a flexible ECM gel network. The rigid framework enables high‑capacity CO storage and sonodynamic bacterial killing, while the flexible ECM gel controls sustained CO release, collectively eradicating multidrug‑resistant infection and promoting scarless healing.

Pyrazole‐Derived Antibacterial Compounds Effectively Treat Methicillin‐Resistant Staphylococcus Aureus Infections by Inhibiting Aspartate Transcarbamoylase

Advanced Science, EarlyView.
This study unveils a novel antibacterial mechanism against MRSA, in which the compound Py‐27 selectively targets and inhibits aspartate transcarbamoylase (ATCase), a key enzyme in pyrimidine synthesis. This inhibition disrupts DNA replication, induces oxidative damage, leading to potent bactericidal activity.

MICROSCOPY | Confocal Laser Scanning Microscopy

, 2014
Confocal laser scanning microscopy (CLSM) is a versatile fluorescence-imaging tool that can visualize in situ microorganisms in their three-dimensional environments and probe their natural microhabitats (biofilms, food matrix, gut, etc.).

Towards many colors in FISH on 3D-preserved interphase nuclei [PDF]

, 2006
The article reviews the existing methods of multicolor FISH on nuclear targets, first of all, interphase chromosomes. FISH proper and image acquisition are considered as two related components of a single process.

Programmable Encapsulation Enables On‐Demand Proliferation of Therapeutic Bacteria for Potent Cancer Immunotherapy

Advanced Science, EarlyView.
A programmable encapsulation technology is developed to reduce bacterial immunogenicity and proliferation after systemic administration. The cross‐linked polymer networks around individual bacteria enable immunogenic shielding and permit selective proliferation in tumors, allowing the bacteria to convert tumor‐accumulated ammonia into L‐arginine and ...

Differences of size and shape of active and inactive X-chromosome domains in human amniotic fluid cell nuclei [PDF]

, 1993
It is a widely held belief that the inactive X-chromosome (Xi) in female cell nuclei is strongly condensed as compared to the largely decondensed active X-chromosome (Xa).

Nanovesicles With Mechanically Induced Adjuvanticity for Robust Melanoma Vaccination Toward Tumor‐Associated Macrophages

Advanced Science, EarlyView.
Rigidity‐tunable nanovesicle (P‐Pm) with mechanically induced adjuvanticity toward tumor‐associated macrophages (TAMs) was designed to engineer R848/gp100 antigen ‐loaded nanovaccine (P@Rg‐Pm), which achieved outstanding anti‐tumor outcomes in both therapeutic and preventive model of B16‐F10 melanoma.
