Evaluating microvascular invasion in hepatitis B virus-related hepatocellular carcinoma based on contrast-enhanced computed tomography radiomics and clinicoradiological factors.

Background: Microvascular invasion (MVI) is a significant indicator of the aggressive behavior of hepatocellular carcinoma (HCC). Expanding the surgical resection margin and performing anatomical liver resection may improve outcomes in patients with MVI. However, no reliable preoperative method currently exists to predict MVI status or to identify patients at high-risk group (M2).

Computed tomography-based radiomics to predict early recurrence of hepatocellular carcinoma post-hepatectomy in patients background on cirrhosis.

Background: The prognosis for hepatocellular carcinoma (HCC) in the presence of cirrhosis is unfavourable, primarily attributable to the high incidence of recurrence.

Aim: To develop a machine learning model for predicting early recurrence (ER) of post-hepatectomy HCC in patients with cirrhosis and to stratify patients' overall survival (OS) based on the predicted risk of recurrence.

Methods: In this retrospective study, 214 HCC patients with cirrhosis who underwent curative hepatectomy were examined.

Field emission and optical properties of ZnO nanowires grown directly on conducting brass substrates.

Large-area and uniform ZnO nanowires have been produced directly on a conducting brass substrate by annealing a Cu0.66Zn0.34 foil under a mixture of argon and oxygen.

Direct growth of quasi-aligned ultrafine ZnS nanowire arrays on conducting zinc foils and their field emission properties.

Quasi-aligned ultrafine ZnS nanowire arrays have been grown directly on zinc substrates via a simple hydrothermal method. The morphology, structure, and composition are characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy and energy-dispersive X-ray spectroscopy. The single-crystalline ultrafine ZnS nanowires have a hexagonal structure with typical diameters of 5-15 nm and lengths of up to micrometers.

Synthesis and field emission properties of rutile TiO2 nanowires arrays grown directly on a Ti metal self-source substrate.

Large-area and uniform quasi-aligned titanium oxide (TiO2) nanowire arrays have been produced in situ on a titanium (Ti) foil by a simple high-temperature oxidation process with acetone as the oxidant. The products are characterized by X-ray diffraction, electron microscopy, energy-dispersive X-ray spectroscopy, X-ray photoelectron spectroscopy, and Raman spectroscopy. The TiO2 nanowires have a rutile single-crystalline structure.
