Immunotherapy is a novel treatment option for various types of cancers. However, the optimal timing for response evaluation has not been well defined. Here, we present a gastric cancer (GC) patient with microsatellite instability-high who experienced recurrence 5 years and 11 months after radical gastrectomy. Then, the patient was treated with radiotherapy, targeted drugs, and immunotherapy. Immunotherapy resulted in 5 months of continuous progression, accompanied by significantly increased tumor marker CA19-9. However, the patient exhibited a satisfactory response without altering the treatment. Based on this, we hypothesized that some persistent progression with elevated tumor markers, known as pseudoprogression (PsP), might be observed in patients with recurrent GC during immunotherapy. This process might be prolonged, but if the treatment is continued, it will eventually produce remarkable therapeutic effects. PsP might challenge the globally accepted immune response evaluation criteria for solid tumors.

Pressure Sensor Array Based on Four DNA-Nanoenzymes with Catalase-like Activity for Portable Multiple Detection of Foodborne Pathogens.

This study has developed a pressure sensor array based on four functionalized DNA-nanoenzymes with catalase-like activity for multiple detections of foodborne pathogens through a portable pressure manometer. Benefiting from functionalization of 4-mercaptophenylboronic acid and β-mercaptoethylamine, the diversity of nonspecific interactions between four DNA-nanoenzymes and each of the nine bacteria leads to differences in pressure response patterns by catalyzing HO to generate exclusive "fingerprints". As effective statistical tools for processing multivariate data, principal component analysis and hierarchical clustering analysis are employed to identify nine foodborne pathogens by analyzing pressure response patterns.

Background: Hyaluronic acid (HA) fillers are commonly used in esthetic medicine for facial contouring and rejuvenation. However, complications such as overcorrection, vascular occlusion, and irregular filler distribution necessitate the use of hyaluronidase to dissolve the fillers. This study aimed to evaluate the efficacy of hyaluronidase in degrading different types of HA fillers and provide clinical guidelines for its use based on filler type, dosage, and application techniques.

Traditionally, this state has been viewed as a tumor-suppressing mechanism that prevents the proliferation of damaged cells while activating the immune response for their clearance. However, senescence is increasingly recognized as a contributing factor to tumor progression.
