Bimetallic nanoreactor mediates cascade amplification of oxidative stress for complementary chemodynamic-immunotherapy of tumor.

As a promising tumor treatment, chemodynamic therapy (CDT) can specifically catalyze HO into the cytotoxic hydroxyl radical (·OH) via Fenton/Fenton-like reaction. However, the limited HO and weakly acidic pH in tumor microenvironment (TME) would severely restrict the therapeutic efficiency of CDT. Here, a weakly acid activated, HO self-supplied, hyaluronic acid (HA)-functionalized Ce/Cu bimetallic nanoreactor (CBPNs@HA) is elaborately designed for complementary chemodynamic-immunotherapy.

A GSH-responsive oxidative stress nanoamplifier for self-augmented chemo/chemodynamic therapy to reverse cisplatin resistance.

Drug resistance and off-target toxicity of cisplatin (CDDP) pose significant challenges in effectively treating non-small cell lung cancer (NSCLC). Recently, chemodynamic therapy (CDT), an emerging reactive oxygen species (ROS)-mediated tumor-specific therapeutic modality, has shown great potential in sensitizing multidrug resistance tumor cells. Herein, a glutathione (GSH)-responsive Pt(IV) prodrug-based oxidative stress nanoamplifier (CuBSO@Pt) was developed for effective chemo/chemodynamic therapy to reverse CDDP resistance in NSCLC.

Molecular Imaging of Ovarian Follicles and Tumors With Near-Infrared II Bioconjugates.

Follicular tracking is typically conducted using ultrasound technology, but its effectiveness is constrained by limited resolution. High-resolution imaging of deep tissues can be accomplished using luminescence imaging in the near-infrared II window (NIR-II, 1000-1700 nm); however, the contrast agents that are used lack specificity. Here, it is reported that the FDA-approved indocyanine green (ICG)-conjugated recombinant human chorionic gonadotropin (hCG) protein can target early follicles with long-term effectiveness.

However, there is a notable lack of research focusing on their prognostic implications specifically in the early stage of gastric cancer. This study aims to investigate the prognostic indicators of early gastric cancer (EGC), including neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), SII, PNI, and lymph node metastasis (LNM).

Liver cirrhosis complicated with pulmonary Nocardia infection: A case report and literature review.

Rationale: Nocardia is a conditionally pathogenic bacterium found in the natural environment and is an aerobic bacterium, which causes severe pneumonia relatively rarely. The diagnosis of primary Nocardia infection is always made late due to the nonspecific clinical presentation of patients with Nocardia infection and the time required for Nocardia culture. Due to its rarity and nonspecific clinical presentation, patient survival is often compromised due to misdiagnosis.

Progression and perspectives in disease modeling for Juvenile myelomonocytic leukemia.

Juvenile myelomonocytic leukemia (JMML) is a rare myeloproliferative neoplasm occurring in infants and young children. JMML has been shown to be resistant to all conventional cytotoxic chemotherapy drugs, and current curative therapies still rely on hematopoietic stem cell transplantation, which carries a high risk of relapse post-transplantation. This underscores the urgent need for novel treatment strategies.

Lactate/Cysteine Dual-Consuming Probiotic-Nanomedicine Biohybrid System for Enhanced Cancer Chemo-Immunotherapy.

Immunotherapy is revolutionizing oncology, but its therapeutic efficiency is still limited by the off-target toxicities and poor antitumor immune responses. By integrating the drug-loaded nanoparticles (DMnSH) with the unique metabolic traits of (Vei), a probiotic-nanomedicine conjugate Vei@DMnSH biohybrid is elaborately designed for enhanced cancer chemo-immunotherapy. Specifically, Vei@DMnSH can accumulate in hypoxic tumor sites and simultaneously consume lactate and cysteine to reverse the lactate-associated immunosuppression and impede the biosynthesis of GSH.
