Multicenter Study on Transarterial Chemoembolization Combined with Radiofrequency Ablation for Early-Stage Hepatocellular Carcinoma: Primary versus Recurrent HCC.

Purpose: To evaluate the efficacy of transarterial chemoembolization (TACE) combined with radiofrequency ablation (RFA) for both primary and recurrent early-stage hepatocellular carcinoma (HCC) and to analyze the significant prognostic factors.

Patients And Methods: Data from patients with early-stage primary or recurrent HCC who underwent TACE plus RFA between August 2019 and May 2024 were collected from three major general hospitals. 158 patients were divided into a primary group and a recurrent group on the basis of their baseline characteristics.

Effects of external electric field on the sensing property of volatile organic compounds over Janus MoSSe monolayer: a first-principles investigation.

Janus 2D transition metal dichalcogenide (TMD) is a new generation 2D material with a unique asymmetric structure. This asymmetric structure (or out-off plane symmetric geometry) of Janus 2D TMD has been reported to yield tunable electronic properties through strain and electric field, which can also be applied in gas sensing. In this work, we performed DFT calculations to investigate the gas sensing property of cyclohexane and acetone on MoS and Janus MoSSe monolayers under external electric fields.

Z-Ligustilide Induces c-Myc-Dependent Apoptosis Activation of ER-Stress Signaling in Hypoxic Oral Cancer Cells.

Z-ligustilide (or ligustilide) is found in () and may exert potential benefits in cancer treatment. Previous research has reported that ligustilide has anti-cancer effects on several types of cancer cells. However, studies of ligustilide on oral cancer cells have not been reported, especially under hypoxic conditions.

Evaluation of efficacy of transcatheter arterial chemoembolization combined with computed tomography-guided radiofrequency ablation for hepatocellular carcinoma using magnetic resonance diffusion weighted imaging and computed tomography perfusion imaging: A prospective study.

Background: The purpose of this study is to evaluate the efficacy of transcatheter arterial chemoembolization (TACE) combined with computed tomography-guided radiofrequency ablation (CT-RFA) in the treatment of hepatocellular carcinoma (HCC) using magnetic resonance diffusion weighted imaging (MR-DWI) and CT perfusion imaging (CT-PI).

Methods: From January 2008 to January 2014, a total of 522 HCC patients receiving TACE combined with CT-RFA were included in this study. All patients underwent TACE followed by CT-RFA, and 1 day before treatment and 1 month after treatment they received MR-DWI and CT-PI.

Evaluation of the characteristics of hepatic focal nodular hyperplasia: correlation between dynamic contrast-enhanced multislice computed tomography and pathological findings.

Objective: To evaluate the characteristics of enhancement of focal nodular hyperplasia (FNH) of the liver by analyzing the dynamic contrast-enhanced multislice computed tomography (MSCT) features and correlating them with pathological findings.

Patients And Methods: Nine males and 16 females with pathologically confirmed FNH and complete preoperative contrast-enhanced MSCT data were recruited for this study. The imaging features of FNH on the pre- and postcontrast MSCT were analyzed by two experienced radiologists by consensus.

Anomalous optical absorption in metallic gratings with subwavelength slits.

The absorption in metallic gratings with subwavelength slits is theoretically investigated. Anomalous optical absorption occurs over a wide range of incident angles for both polarizations. In particular, a nearly perfect absorbance up to 99.

Multiple Fano resonances in metallic arrays of asymmetric dual stripes.

Characteristics of Fano resonances in metallic arrays of asymmetric dual stripes are theoretically investigated. The structure consists of two perfect metal stripes with unequal sizes in a unit cell. In addition to the total reflection that usually occurs in single-stripe arrays, the dual-stripe arrays exhibit two extra pairs of reflection peaks and dips, which are identified as the Fano resonance with the reflection line shape characterized by a Fano formula.

[Feasibility study on CT guided percutaneous incisional needle biopsy for deep pelvic masses by different puncture approaches].

Objective: To explore the feasibility of CT guided percutaneous incisional needle biopsy (PINB) for deep pelvic masses at different locations via various puncture approaches.

Methods: PINBs under CT guidance were performed in 70 patients with 72 pelvic lesions through different puncture approaches. Their pathological findings and safety were evaluated after follow-up of a period of 1-34 months.
