The sphingolipid metabolic pathway, an important signaling plays a crucial role in various physiological processes including cell proliferation, survival, apoptosis, and immune regulation. liver has the unique ability to regenerate using bioactive lipid mediators involving multiple sphingolipids, ceramide sphingosine 1-phosphate (S1P). Dysregulation of balance between sphingomyelin, ceramide, S1P been implicated regulation regeneration diseases, fibrosis hepatocellular carcinoma (HCC)....

Postoperative changes in body composition (BC) have not been clearly defined. The aim of this study was to clarify the impact postoperative comprehensive BC on long-term prognosis gastric cancer (GC) patients. A total 366 GC patients who underwent radical gastrectomy were included. skeletal muscle volume, fat and density investigated at six months postoperatively using computed tomography evaluated their association with survival. Patients decreased increased had a poor prognosis,...

Objective: The diagnostic efficacy of the apparent diffusion coefficient (ADC) on diffusion-weighted magnetic resonance imaging for lymph node metastasis in biliary tract cancer was investigated present study. Methods: Surgically resected 112 nodes from 35 (BTC) patients were examined this Values ADC mean and minimum nodes, as well short-axis long-axis diameters assessed by computed tomography (CT). relationship between these parameters presence histological evaluated. Results: Histological...
