Article Abstract

We present a recombineering-based method for editing the genome of a temperate phage. The method uses the lambda Red recombination system to edit the genome of a lysogenized host with a prophage compatible with bacteriophage lambda. Linear DNA is used as the recombination substrate and antibiotic resistance is used as the basis for selection of recombinants. The method enables the genetic manipulation of a prophage in 3-5 days.

Amyloidosis encompasses a spectrum of rare disorders characterized by extracellular amyloid deposition. Achieving an accurate early diagnosis of systemic amyloidosis necessitates biopsy-specific pathological evaluation. Formalin-fixed, paraffin-embedded liver biopsy specimens were examined using Congo red staining, electron microscopy, immunohistochemistry (IHC), immunofluorescence, and Congo red-assisted laser microdissection with mass spectrometry (LMD/MS).

Background: Hexavalent chromium ions (Cr(VI)), a notorious toxic heavy metal pollutant with proven carcinogenicity, endangers human health and the environment. Meanwhile, l-ascorbic acid (L-AA), a vital biological antioxidant, has abnormal levels closely tied to various diseases. Developing efficient synchronous detection methods for these two key analytes is of great value in clinical and environmental monitoring.

The development of multifunctional nanoplatforms capable of drug delivery and real-time cellular imaging remains a key challenge in cancer theranostics. Herein, we report the development of a casein-protected maleic acid-derived nitrogen-doped carbon dot-based luminescent nanoplatform (MNCD@Cas NPs) for efficient delivery of the anticancer drug doxorubicin hydrochloride (DOX) to triple-negative breast cancer cells. Synthesized via a facile two-step method, the MNCD@Cas NPs exhibit bright blue fluorescence (λ = 390 nm), high water dispersibility, excellent colloidal stability, and substantial DOX loading capacity (∼84%) driven by electrostatic interactions.

Circularly polarized room-temperature phosphorescent (CP-RTP) materials have been attracting great attention due to their potential applications in anticounterfeiting. In this study, we designed and synthesized a host-guest copolymer () with strong phosphorescence emission and a long emission lifetime using a self-doping strategy. The co-assembled liquid crystal polymer networks / doped with demonstrated a stronger RTP emission and longer lifetime (τ = 148 ms).

A single fluorescent probe for simultaneous detection of polarity, viscosity, and esterase.

State Key Laboratory of Applied Organic Chemistry and College of Chemistry and Chemical Engineering, Lanzhou University, Lanzhou, 730000, China. Electronic address:

Background: The dynamic interplay between esterase activity and physicochemical microenvironments-such as polarity and viscosity-is critical for decoding early cellular dysfunction in processes like apoptosis, ferroptosis, and drug-induced toxicity. However, conventional probes typically report only a single parameter, obscuring interdependent changes in enzyme activity and membrane properties. This technological gap limits our ability to capture real-time, spatially resolved fluctuations within subcellular compartments.
