Hepatocellular carcinoma (HCC) is the sixth most common malignant tumor, highlighting a significant need for reliable predictive models to assess clinical prognosis, disease progression, and drug sensitivity. Recent studies have highlighted the critical role of various programmed cell death pathways, including apoptosis, necroptosis, pyroptosis, ferroptosis, cuproptosis, entotic cell death, NETotic cell death, parthanatos, lysosome-dependent cell death, autophagy-dependent cell death, alkaliptosis, oxeiptosis, and disulfidptosis, in tumor development. Therefore, by investigating these pathways, we aimed to develop a predictive model for HCC prognosis and drug sensitivity.

Background: Hepatocellular carcinoma (HCC) is the most common malignant liver disease in the world. Platelets (PLTs) are known to play a key role in the maintenance of liver homeostasis and the pathophysiological processes of a variety of liver diseases. Aspirin is the most classic antiplatelet agent.

Pseudoaneurysms of the neck are seldom, and those caused by neck infections especially parapharyngeal abscess are even rarer. However, it is life-threatening and may bring sudden death due to the obstruction of airway and the pseudoaneurysms rupture. We analyzed the clinical features, diagnosis and treatment of the disease through a case summary and literature review in order to guide clinical diagnosis and treatment of pseudoaneurysms.

Metabolomics has become a promising method for understanding pathological mechanisms. Plasma (PLS) is the most common sample type used for metabolomics studies, and dried blood spot (DBS) sampling has been regarded as a good strategy due to its unique characteristics. However, how results obtained from DBS can be correlated to results obtained from PLS remains unclear.

Background: With the withdrawal of paraquat from the market, diquat is widely used, so the treatment of diquat poisoning has become one of the focuses of emergency poisoning diagnosis and treatment.

Case Summary: We studied the case of a 17-year-old male patient who drank 200 mL (20 g/100 mL) of diquat solution two hours before arriving at the hospital. Despite the use of treatments such as gastric lavage, hemoperfusion, continuous hemodialysis, glucocorticoids, and organ support, the patient's condition rapidly progressed to multiorgan failure, and he died 23.

Article Synopsis
  • Bacteraemia (SAB) is a significant cause of both bacteraemia and infectious endocarditis (IE), with about 5-12% of SAB patients developing IE, particularly in adults with skin issues like epidermolytic hyperkeratosis (EHK).
  • A 43-year-old male presented with fever and skin diseases, later diagnosed with EHK following genetic tests, which contributed to his SAB and IE.
  • The combination of a compromised skin barrier due to EHK and poor sanitation led to bacterial infections; hence, it's crucial to diagnose and treat EHK early to prevent serious complications like IE and organ abscesses.

invasion syndrome (KPIS) is a critical multi-site infection that is usually caused by highly virulent . It is relatively common in Asian patients with diabetes and leads to sepsis, which has a high mortality rate. We report the case of a man in his early 40s who presented to the hospital with blurred vision in his left eye of 7 days' duration and fever of 1 day's duration.

Objective: To study the effect of outer membrane vesicles (OMVs) derived from (ST) on the ultrastructural features and immune function of dendritic cells (DC).

Methods: Mice bone marrow cells were collected aseptically, and myeloid DC were generated by the combined induction and amplification with recombinant mouse granulocyte-macrophage colony-stimulating factor (GM-CSF) and recombinant mouse interleukin-4 (rm IL-4). Cell morphology was observed under inverted phase contrast microscope and the phenotype was identified with flow cytometry.

Tissue inhibitor of metalloprotease-1 (TIMP-1) is a tissue inhibitor of matrix metalloproteinases (MMPs). It however exerts multiple effects on biological processes, such as cell growth, proliferation, differentiation and apoptosis, in an MMP-independent manner. This study aimed to examine the role of TIMP-1 in adipogenesis of adipose-derived stem cells (ASCs) and the underlying mechanism.

Targeting mGluR5 has been an attractive strategy to modulate glutamate excitotoxicity for neuroprotection. Although human clinical trials using mGluR5 negative allosteric modulators (NAMs) have included some disappointments, recent investigations have added several more attractive small molecules to this field, providing a promise that the identification of more additional strategies to modulate mGluR5 activity might be potentially beneficial for the advancement of PD treatment. Here, we determined the role of the interacting partner CAL (cystic fibrosis transmembrane conductance regulator-associated ligand) in mGluR5-mediated protection in vitro and in vivo.

Sensitive and specific non-invasive biomarkers are urgently needed in order to improve the survival of patients with pancreatic ductal adenocarcinoma (PDAC), which is the fourth leading cause of cancer-related death. We aim to identify serum hub miRNAs as potential diagnostic and prognostic biomarkers for PDAC. A total of 2578 serum miRNA expression data from 88 PDAC patients and 19 healthy subjects were downloaded from the Gene Expression Omnibus database.

  • * Findings indicated that while CTLA-4 inhibitors were associated with a slight increase in all-grade lipase elevation (RR 1.05), there was no significant increase in pancreatitis risk when compared to chemotherapy or placebo.
  • * Furthermore, the combination treatment of nivolumab and ipilimumab showed a notably higher risk of amylase and lipase elevations, but did not result in a significant rise in pancreatitis compared to control therapies.

The catalytic activity of counter electrodes (CEs) severely restricts the photovoltaic conversion efficiency of dye-sensitized solar cells. However, electrons trapped by bulk defects greatly reduce the catalytic activity of the CE. In this study, we report a novel InS-C-Au hybrid structure designed by simply decorating Au particles on the surface of carbon-coated hierarchical InS flower-like architectures, which could avoid the abovementioned problems.

Decorin (DCN) is a major member of the small leucine-rich proteoglycan (SLRP) family that is critically involved in tumorigenesis and the development of metastasis of cancers, including glioma. Overexpression of DCN was indicated to suppress glioma cell growth. However, the role of DCN in the migration of glioma cells remain elusive.

Glioma is a most common type of primary brain tumors. Extracellular vesicles, in the form of exosomes, are known to mediate cell-cell communication by transporting cell-derived proteins and nucleic acids, including various microRNAs (miRNAs). Here we examined the cerebrospinal fluid (CSF) from patients with recurrent glioma for the levels of cancer-related miRNAs, and evaluated the values for prognosis by comparing the measures of CSF-, serum-, and exosome-contained miR-21 levels.

The technology of virus-based genetic modification in tissue engineering has provided the opportunity to produce more flexible and versatile biomaterials for transplantation. Localizing the transgene expression with increased efficiency is critical for tissue engineering as well as a challenge for virus-based gene delivery. In this study, we tagged the VP2 protein of type 2 adeno-associated virus (AAV) with a 3×FLAG plasmid at the N-terminus and packaged a FLAG-tagged recombinant AAV2 chimeric mutant.

Exosomes secreted by various types of living cells are small vesicular bodies that contain many types of proteins and RNAs. Such membrane-coated nano-scale structures are extensively involved in the processes of intercellular material exchange and signal communication, thus to conduct important functions under physiological and pathological conditions. Exosomes exist in high abundance in a wide range of body fluids, including peripheral blood, urine, ascites, and amniotic fluid, etc.
