A series of 1,3-diaryl-2-propenones 2a-j and analogous 2-benzylidene-1,3-indandiones 3a-j were evaluated against various neoplasms and normal cells. In general, greater cytotoxic potencies and selective toxicity to human malignant cells were observed by the compounds in series 2 rather than 3. In particular, 2i emerged as a lead molecule having an average CC(50) figure of 8.6 µM and a selective index value of 18. Various physicochemical features of 2a-j were correlated with the cytotoxic potencies to neoplastic cell lines which provide guidelines for expansion of this series of compounds. The enone 2i induced internucleosomal DNA fragmentation and activated caspase-3 in HL-60 cells suggesting that one of the ways in which the cytotoxicity of the compounds in series 2 is mediated towards some of the cell lines used in this study is by apoptosis. Neurotoxicity in mice was generally lower in series 2 than 3a-j.

Gastric cancer is a significant health concern worldwide, and its diagnosis and management are of paramount importance. Ectopic pancreas (EP) refers to an embryological abnormality where healthy pancreatic tissue develops without anatomical, vascular, or neural communication with the normal pancreas. We report the case of a patient whose initial endoscopic evaluation suggested early gastric cancer, but computed tomography scan (CT scan) and endoscopic ultrasound (EUS) indicated a locally advanced tumor.

Background: Palliative spine radiation therapy is prone to treatment at the wrong anatomic level. We developed a fully automated deep learning-based spine-targeting quality assurance system (DL-SpiQA) for detecting treatment at the wrong anatomic level. DL-SpiQA was evaluated based on retrospective testing of spine radiation therapy treatments and prospective clinical deployment.

Cyclooxygenase-2 (COX-2) plays a crucial role in inflammation and has been implicated in cancer development. Understanding the behavior of COX-2 in different cellular contexts is essential for developing targeted therapeutic strategies. In this study, we investigate the fluorescence spectrum of a fluorogenic probe, NANQ-IMC6, when bound to the active site of human COX-2 in both its monomeric and homodimeric forms.
