Article Synopsis
  • Metastatic disease and cancer recurrence are major causes of cancer-related deaths, largely driven by circulating tumor cells (CTCs) and disseminated tumor cells (DTCs).
  • Liquid biopsy, which uses rare CTCs for early-stage tumor detection, is a promising minimally invasive technique that enhances tumor management.
  • To effectively utilize liquid biopsy, precise isolation of CTCs and their molecular identification through advanced technologies is essential for understanding cancer heterogeneity and improving diagnosis and monitoring.

Article Synopsis
  • - Cancer is a top cause of death globally, and understanding its complex mechanisms is essential for developing effective treatments, making innovative approaches crucial.
  • - Organ-on-a-chip (OoC) technology is emerging as a promising solution for the pharmaceutical industry, helping to reduce research costs and improve cancer treatment simulations in a 3D microenvironment.
  • - This article reviews recent advancements in OoC systems, highlighting their potential for better tumor modeling, and examines both the benefits and drawbacks of using this technology in cancer therapy.

The heterogeneity of the solid tumor microenvironment (TME) impairs the therapeutic efficacy of standard therapies and also reduces the infiltration of antitumor immune cells, all of which lead to tumor progression and invasion. In addition, self-renewing cancer stem cells (CSCs) support tumor dormancy, drug resistance, and recurrence, all of which might pose challenges to the eradication of malignant tumor masses with current therapies. Natural forms of oncolytic viruses (OVs) or engineered OVs are known for their potential to directly target and kill tumor cells or indirectly eradicate tumor cells by involving antitumor immune responses, including enhancement of infiltrating antitumor immune cells, induction of immunogenic cell death, and reprogramming of cold TME to an immune-sensitive hot state.

Plant-derived immunomodulators and antitumor factors have appealed lots of attention from natural product scientists for their efficiency and safety and their important contribution to well-designed targeted drug action and delivery mechanisms. Zerumbone (ZER), the chief component of Zingiber zerumbet rhizomes, has been examined for its wide-spectrum in the treatment of multi-targeted diseases. The rhizomes have been used as food flavoring agents in numerous cuisines and in flora medication.

Immunotherapies using immune checkpoint inhibitors (ICIs) and chimeric antigen receptor (CAR) T-cell therapy have achieved successful results against several types of human tumors, particularly hematological malignancies. However, their clinical results for the treatment of solid tumors remain poor and unsatisfactory. The immunosuppressive tumor microenvironment (TME) plays an important role by interfering with intratumoral T-cell infiltration, promoting effector T-cell exhaustion, upregulating inhibitory molecules, inducing hypoxia, and so on.

In this study, an essential application of remote sensing using deep learning functionality is presented. Gaofen-1 satellite mission, developed by the China National Space Administration (CNSA) for the civilian high-definition Earth observation satellite program, provides near-real-time observations for geographical mapping, environment surveying, and climate change monitoring. Cloud and cloud shadow segmentation are a crucial element to enable automatic near-real-time processing of Gaofen-1 images, and therefore, their performances must be accurately validated.

Objective: To evaluate whether cesarean delivery is a risk factor for emergent postpartum hysterectomy.

Methods: We performed a case-control study of patients who delivered at Women & Infants Hospital between January 1989 and February 2000. Fifty cases of emergent postpartum hysterectomy performed within 14 days of delivery met our inclusion criteria.
