Identification and Validation of Nicotinamide Metabolism-Related Gene Signatures as a Novel Prognostic Model for Hepatocellular Carcinoma.

Background: Nicotinamide (NAM+) regulates redox and metabolic activities in the mitochondria. The intention of the research was to identify key genes that relate to nicotinamide in hepatocellular carcinoma (HCC).

Methods: Relevant clinical information were collected as well as RNA-seq data using the Cancer Genome Atlas (TCGA) database.

Integrative analysis of lactylation-related genes and establishment of a novel prognostic signature for hepatocellular carcinoma.

Background: Lactylation has been found to involve in regulating many types of biological process in cancers. However, research on lactylation-related genes in predicting the prognosis of hepatocellular carcinoma (HCC) remains limited.

Methods: The differential expression of lactylation-related genes (EP300 and HDAC1-3) in pan-cancer were examined in public databases.

Fluorescent Laparoscopic Central Hepatectomy for Liver Cancer Using Indocyanine Green Negative Staining.

Laparoscopic hepatectomy is an important treatment method for liver cancer. In the past, the resection boundary was usually determined by intraoperative ultrasound, important vascular structures, and surgeon experience. With the development of anatomical hepatectomy, visual surgery technology has gradually been applied to this type of surgery, particularly indocyanine green (ICG)-guided anatomical hepatectomy.

Case Report: Hepatic Artery Infusion Chemotherapy After Stage I ALPPS in a Patient With Huge HCC.

Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) can induce rapid hypertrophy of the liver remnant. However, with a background of liver cirrhosis or other chronic liver diseases, patients with a huge hepatocellular carcinoma (HCC) may sometimes face insufficiency of hepatocellular regeneration after associating liver partition and portal vein ligation for staged hepatectomy (ALPPS). Herein, we report a 56-year-old male with a vast HCC (13.

Angiopoietin-2 induces angiogenesis via exosomes in human hepatocellular carcinoma.

Background: Hepatocellular carcinoma (HCC) is the most common primary liver cancer and is a highly vascularized solid tumor. Angiopoietin-2 (ANGPT2) has been described as an attractive target for antiangiogenic therapy. Exosomes are small extracellular vesicles secreted by most cell types and contribute to cell-to-cell communication by delivering functional cargo to recipient cells.

Hypersonic Aerodynamic Force Balance Using Micromachined All-Fiber Fabry⁻Pérot Interferometric Strain Gauges.

This paper presents high-sensitivity, micromachined all-fiber Fabry-Pérot interferometric (FFPI) strain gauges and their integration in a force balance for hypersonic aerodynamic measurements. The FFPI strain gauge has a short Fabry-Pérot cavity fabricated using an excimer laser etching process, and the deformation of the cavity is detected by a white-light optical phase demodulator. A three-component force balance, using the proposed FFPI gauges as sensing elements, was fabricated, calibrated, and experimentally evaluated.
