Stromal immune cells expression of Siglec-15 is associated with lower T stage and better prognosis of urinary bladder cancer.

Introduction: Sialic acid-binding immunoglobulin-like lectin 15 (Siglec-15) is a novel immune checkpoint, similar to programmed death-ligand (PD-L1), and has emerged as a potential target for cancer immunotherapy. Until recently, little was known about the expression and role of Siglec-15 in bladder cancer (BC).

Methods: In this study, we used immunohistochemical staining to assess the expression of Siglec-15 and PD-L1 in 69 primary BC samples and analyzed their relationship with clinicopathologic characters and prognosis.

Psychiatric morbidity among SARS and COVID-19 survivors at 30 months post-infection.

Background: Severe acute respiratory syndrome (SARS) and COVID-19 are both highly infectious diseases that cause severe respiratory illness. This study aimed to compare survivors of SARS and COVID-19 and identify factors associated with long-term psychiatric comorbidities.

Methods: This was a retrospective cohort study of adult Chinese survivors of SARS and COVID-19 who had been admitted to the United Christian Hospital, Hong Kong.

Visualizing Hydrogen Peroxide Diffusion in Soils with Precipitation-Based Fluorescent Probe.

Hydrogen peroxide (HO)-based advanced oxidation technology has emerged as a cost-effective and green solution for tackling soil pollution. Given the highly heterogeneous nature of soil, the effectiveness of HO remediation is significantly influenced by its diffusion distance in soils. However, the dynamics of HO diffusion and its effective range remain largely unexplored, primarily due to the lack of analytical methods for mapping HO in soils.

Mechanistic insights into the anti-oxidative and anti-inflammatory functions of covalent-reactive cinnamyl compounds within Cinnamomum cassia.

Background: Cinnamomum cassia Presl (Lauraceae) is widely used as a medicinal plant in the folk medicine and pharmaceutic industry, for its promising anti-inflammatory, anti-oxidative, and anti-bacterial function. However, the major bioactive components were still in debate, and their underlying molecular mechanism was not yet fully understood.

Purpose: This study aimed to identify the bioactive ingredients of C.
