Accurately detecting cysteine (Cys) in vivo is crucial for diagnosing Cys-related diseases. A novel ratiometric fluorescent probe featuring dual near-infrared emission is developed in this study for the in vivo ratio imaging of Cys. The probe comprises a hemicyanine organic small-molecule dye (HCy-CYS) with specific Cys recognition capabilities covalently coupled with carbon dots (CDs) synthesized using glutathione (GSH) as the carbon source (GCDs), forming a unique composite nanofluorescent probe (GCDs@CYS).

In this study, an mRNA-initiated autonomous multi-shRNA nanofactory (RNF@CM) is designed for in vivo amplification imaging and precise cancer treatment. The RNF@CM consists of a gold nanoparticle core, an interlayer of two types of three-stranded DNA/RNA hybrid probes, one of which is bound to aptamer-inhibited DNA polymerases, and an outer layer of the cancer cell membrane.

Copper peptide, a low molecular weight peptide composed of glycyl-L-histidyl-l-lysine-copper, possesses anti-aging, anti-inflammatory, and wound healing properties. In this study, we investigated the effects of a combination agent CP-AcT, composed of palmitoyl copper peptide (pal-GHK-Cu) and acetyl tyrosine (N-Acetyl-l-tyrosine), on melanin production in the human malignant melanoma cell line A375 and the mouse melanoma cell line B16. Firstly, the cytotoxicity of CP-AcT at various concentrations (0-8 μg/mL) on HaCat, HFF, A375, and B16 cells was evaluated.

The strains were acquired from athickened sludge in a fluorine chemical park. Each strain's EPS were isolated by heating and centrifugation, and their growth, metabolic activity, and EPS alteration research pre- and post-stress were assessed and compared.

While numerous methods exist for diagnosing tumors through the detection of miRNA within tumor cells, few can simultaneously achieve both tumor diagnosis and treatment. In this study, a novel graphene oxide (GO)-based DNA nanodevice (DND), initiated by miRNA, was developed for fluorescence signal amplification imaging and photodynamic therapy in tumor cells. After entering the cells, tumor-associated miRNA drives DND to Catalyzed hairpin self-assembly (CHA).

We previously reported that vitamin B-6 inhibits macrophage-mediated inflammasome activation.
Objectives: We sought to examine whether the prophylactic use of vitamin B-6 prevents HFpEF.
Nanocatalytic medicine, which aims to accurately target and effectively treat tumors through intratumoral in situ catalytic reactions triggered by tumor-specific environments or markers, is an emerging technology. However, the relative lack of catalytic activity of nanoenzymes in the tumor microenvironment (TME) has hampered their use in biomedical applications. Therefore, it is crucial to develop a highly sensitive probe that specifically responds to the TME or disease markers in the TME for precision diagnosis and treatment of diseases.

Methods: Using data from the UK Millennium Cohort Study, we examined the associations of prospectively collected individual ACEs, ACE scores, and poverty with excessive recreational screen time (>4 hours) across different media types. We ran further analyses to investigate sex differences in the associations of ACEs with excessive screen time.
Background: Cancer stem cells (CSCs) play a significant role in the recurrence and drug resistance of esophageal carcinoma (ESCA). Ferroptosis is a promising anticancer therapeutic strategy that effectively targets CSCs exhibiting high tumorigenicity and treatment resistance. However, there is a lack of research on the combined role of ferroptosis-related genes (FRGs) and stemness signature in the prognosis of ESCA.

However, for ratiometric fluorescence sensors, the output signal is a change in the intensity ratio of two or more emission peaks. The fluorescence intensity of these emission peaks is similarly affected by external factors; thus, these sensors have the ability to self-correct, which can greatly improve the accuracy and reliability of the detection results.
