OBI-992, a Novel TROP2-Targeted Antibody-Drug Conjugate, Demonstrates Antitumor Activity in Multiple Cancer Models.

Trophoblast cell surface antigen 2 (TROP2) is highly expressed in multiple cancers relative to normal tissues, supporting its role as a target for cancer therapy. OBI-992 is an antibody-drug conjugate (ADC) derived from a novel TROP2-targeted antibody linked to the topoisomerase 1 (TOP1) inhibitor exatecan via an enzyme-cleavable hydrophilic linker, with a drug-antibody ratio of 4. This study evaluated and compared the antitumor activity of OBI-992 with that of benchmark TROP2-targeted ADCs datopotamab deruxtecan (Dato-DXd) and sacituzumab govitecan (SG) in cell line-derived xenograft (CDX) and patient-derived xenograft (PDX) models.

Engaging and supporting young adults in smoking cessation: Insights from a mobile-based cessation program in China.

Objective: Evidence-based smoking cessation treatments are underutilized by young adult smokers. This study explored young smokers' experiences with a mobile-based smoking cessation program that included a Quit & Win contest at a university in Zhuhai, China, aiming to identify key engagement and cessation mechanisms.

Methods: Twenty participants (aged 18-25 years) were selected through purposive sampling.

Analysis of Current Status and Influencing Factors of Psychological Distress Tolerance in Liver Cancer Patients after Interventional Therapy.

Background: Interventional therapy, currently, has become a major method for the clinical treatment of liver cancer patients. However, interventional therapy can also lead to various toxic side effects, and combined with the impact of the disease itself, liver cancer patients often experience more severe emotional distress. Improving individuals' levels of psychological distress tolerance may reduce sensitivity to negative life events and experiences.

Trends in Obesity Prevalence Among Adults With Hypertension in the United States, 2001 to 2023.

Background: Obesity is a factor contributing to the occurrence of hypertension and a risk factor for adverse outcomes in populations with hypertension. The changes in the prevalence of obesity in populations with hypertension remain unclear. Investigating the changes in the prevalence of obesity in populations with hypertension can provide information for the treatment and management of hypertension.

Enhancement of Osseointegration via Endogenous Electric Field by Regulating the Charge Microenvironments around Implants.

The regulation of the charged microenvironment around implants is an effective way to promote osseointegration. Although homeostasis of the charged microenvironment plays an integral role in tissues, current research is externally invasive and unsuitable for clinical applications. In this study, functional materials with different surface potential differences are prepared by changing the spatial layout of Ta and Ag on the surface of a Ti-6Al-4V alloy (TC4).
