Article Synopsis
  • - Cancer is the second leading cause of death globally, and about 50% of patients receive radiation therapy, predominantly photon radiation, despite advancements in proton radiation therapy (PBT) that aims to minimize damage to healthy tissue.
  • - Proton therapy utilizes the Bragg peak property of protons to deliver targeted radiation with potentially lower toxicity compared to photon therapy, but patients may still experience proton-specific side effects.
  • - Reported toxicities from proton therapy include issues related to the brain, lungs, heart, gastrointestinal system, and genitourinary system; while similar to those from photon therapy, they generally occur less frequently.

The Croton genus (Euphorbiaceae) is recognized as a promising source for identifying bioactive compounds with antiproliferative activity. However, knowledge on the chemical composition and activity of Croton floribundus, Croton echinocarpus, and Croton zehntneri is limited. Thus, this study aimed to investigate the antiproliferative activity of these species on cells derived from tumoral breast, lung, and melanoma cells, and primary fibroblasts derived from human skin.

Background And Aims: Acute-on-chronic liver failure (ACLF) is the most severe form of acutely decompensated cirrhosis and is characterized by the presence of intense systemic inflammation. Leucocyte quantification can serve as an indirect indicator of systemic inflammation. In our study, we investigated the predictive value of hematological ratios (neutrophils to lymphocytes, monocyte to lymphocytes, platelets to lymphocytes, lymphocytes to C-reactive protein, and neutrophils to lymphocytes and platelets) in acute decompensation (AD) and ACLF patients and their relation to disease severity and early mortality.
