The unexpected PD-L1 suppression function of celery-derived extracellular vesicles improves lung cancer chemotherapy efficacy.

The article explores celery-derived extracellular vesicles (CDEVs), characterized by high cellular uptake, low immunogenicity, and high stability, as a therapeutic strategy for antitumor nanomedicines. The methods employed in this study include cell experiments such as co-culture, Western Blot, and flow cytometry. experiments were conducted in C57BL/6 tumor-bearing mice subcutaneously injected with Lewis lung carcinoma (LLC) cells.

Z-residual diagnostic tool for assessing covariate functional form in shared frailty models.

Survival analysis often involves modeling hazard functions while considering frailty to account for unobserved cluster-level factors in clustered survival data. Shared frailty models have gained popularity for this purpose, but assessing covariate functional form in these models presents unique challenges. Martingale and deviance residuals are commonly used for visually assessing covariate functional form against continuous covariates.

Association between COVID-19 anxiety syndrome and COVID-19 vaccine hesitancy in the postpandemic era: a cross-sectional study in Hong Kong.

Background: The COVID-19 pandemic has had profound psychophysiological and socioeconomic effects worldwide. COVID-19 anxiety syndrome (CAS) is a specific cluster of maladaptive coping strategies, including perseveration and avoidance behaviours, in response to the perceived threat and fear of COVID-19. CAS is distinct from general COVID-19 anxiety.

Establishment and internal validation of a model to predict the efficacy of Adalimumab in Crohn's disease.

Background: Clinically, the ability to distinguish which Crohn's disease patients can benefit from Adalimumab is limited.

Aims: This study aimed to develop a model for predicting clinical remission probability for Crohn's disease patients with Adalimumab at 12 weeks. The model assists clinicians in identifying which Crohn's disease patients are likely to benefit from Adalimumab treatment before starting therapy, thus optimizing individualized treatment strategies.

Prognostic stratification of gastric cancer patients by intratumoral microbiota-mediated tumor immune microenvironment.

Gastric cancer (GC) is a leading cause of cancer-related deaths worldwide, and therapeutic options for advanced GC are limited. Here, we observe that intratumoral microbiota controls chemokine expression, which in turn recruits immune cells into the tumor, and that immune infiltration is strongly associated with patient survival and disease attributes. Furthermore, microbiota regulation of chemokines is differentiated in GC patients with different survival risks.
