Gastric cancer (GC) is a significant global health challenge, particularly in high-incidence regions like East Asia. Despite improvements in screening and treatment, the progressive nature of precancerous lesions-such as atrophic gastritis, intestinal metaplasia, and dysplasia-necessitates effective prevention strategies. This review evaluates the role of chemoprevention in GC, focusing on agents designed to target these precancerous lesions.

Introduction: Folate receptors (FR) have been considered a convenient target for different radiopharmaceuticals in recent years. Multifarious Ga-labeled folate conjugates have been proposed as promising agents for the PET imaging of FR-overexpressing malignant neoplasms. In addition, radiolabeled folate-based conjugates can be effective for imaging non-tumor pathological foci characterized by a pronounced cluster of activated macrophages.

Early recognition of acute kidney injury is essential to prevent progression to chronic kidney disease. We present the case of a 19-year-old man with multiple emergency department visits for fatigue, abdominal pain, and intermittent dark urine. Upon admission, he had pancytopenia with elements suggestive of hemolysis and acute kidney injury.

Inflammatory bowel disease (IBD) presents a significant therapeutic challenge due to the need for oral drug delivery systems that withstand acidic environment of stomach while effectively targeting intestinal inflammation. To address this issue, we created a novel hydrogel system based on a folic acid (FA)-dopamine (DA) conjugate, co-assembled with protocatechuic acid (PCA), to form F-DP hydrogels. These hydrogels demonstrated robust anti-gastric acid, mucosal adhesive, and injectable properties, enhancing their efficacy for targeted delivery.
