Background: Hepatocellular carcinoma (HCC) is a significant health problem associated with several risk factors, increasingly driven by non-alcoholic steatohepatitis and metabolic syndrome. This association poses a challenge for the primary treatments of HCC, which may include immune checkpoint inhibitors and vascular endothelial growth factor inhibitors, due to their potential cardiotoxic effect. Therefore, it is imperative to balance the therapeutic effects of these agents with their potential cardiovascular adverse events.

  • The localization and prognosis evaluation of peripheral nerve injuries is difficult in acute cases, but high-resolution ultrasound (HRUS) may provide a cost-effective imaging solution.
  • A systematic review and meta-analysis of 15 studies demonstrated HRUS's high diagnostic accuracy for traumatic nerve injuries, with sensitivity at 92% and specificity at 86%.
  • The findings suggest that HRUS can effectively complement existing diagnostic methods, but further research is needed to explore the ultrasound characteristics of these injuries.

Artemisinin-based combinational therapies (ACTs) constitute the first line of malaria treatment. However, due to its trichome-specific biosynthesis, low concentration, and poor understanding of regulatory mechanisms involved in artemisinin biosynthesis and trichome development, it becomes very difficult to meet the increased demand for ACTs. Here, we have reported that a bHLH transcription factor, AaMYC2-type, plays an important role in regulating GST development and artemisinin biosynthesis in Artemisia annua.

Forecasting mortality rates is crucial for evaluating life insurance company solvency, especially amid disruptions caused by phenomena like COVID-19. The Lee-Carter model is commonly employed in mortality modelling; however, extensions that can encompass count data with diverse distributions, such as the Generalized Autoregressive Score (GAS) model utilizing the COM-Poisson distribution, exhibit potential for enhancing time-to-event forecasting accuracy. Using mortality data from 29 countries, this research evaluates various distributions and determines that the COM-Poisson model surpasses the Poisson, binomial, and negative binomial distributions in forecasting mortality rates.
