Reassessment of palliative surgery in conversion therapy of previously unresectable hepatocellular carcinoma: Two case reports and review of literature.

Background: Most patients with hepatocellular carcinoma (HCC) have lost the opportunity for direct surgery at the time of diagnosis. Transarterial chemoembolization (TACE) combined with immune checkpoint inhibitors or tyrosine kinase inhibitors (TKI) can partially transform some unresectable HCC and improve the prognosis effectively. However, based on the promising prospects of combined targeted and immunotherapy for the effective treatment of HCC, the positive role of palliative surgery in the conversion treatment of advanced HCC urgently needs further intensive re-assessment.

Zinc finger BED-type containing 3 promotes hepatic steatosis by interacting with polypyrimidine tract-binding protein 1.

Aims/hypothesis: The relationship between metabolic dysfunction-associated steatotic liver disease (MASLD) and type 2 diabetes mellitus, insulin resistance and the metabolic syndrome is well established. While zinc finger BED-type containing 3 (ZBED3) has been linked to type 2 diabetes mellitus and the metabolic syndrome, its role in MASLD remains unclear. In this study, we aimed to investigate the function of ZBED3 in the context of MASLD.

The limited options especially toward HCC with metastasis prompts us to identify novel molecules for either diagnostic/prognostic or therapeutic purposes. GRPEL2 is well defined in maintaining mitochondrial homeostasis, which is critical to multiple biological processes for cancer survival.

The study of spectroscopy and vibrational assignments of high nitrogen material 1,1'-azobis-1,2,3-triazole.

Benefiting from the new strategy of oxidative azo coupling of the N-NH moiety, a series of energetic nitrogen-rich molecules with long catenated nitrogen chains have been successfully synthesized. As one of them, the synthesized 1,1'-azobis-1,2,3-triazole shows excellent thermal stability, great explosive performance, and special photochromic properties, which has caused widespread concern. To further characterize its performance, the structural, electronic, vibrational, mechanical, and thermodynamic properties of 1,1'-azobis-1,2,3-triazole were investigated based on the first-principles density functional theory calculations.
