Objectives: To investigate the value of intralesional and perilesional radiomics based on computed tomography (CT) in predicting the bioactivity of hepatic alveolar echinococcosis (HAE).

Materials And Methods: In this retrospective study, 131 patients who underwent surgical resection and diagnosed HAE in pathology were included (bioactive, n=69; bioinactive, n=62). All patients were randomly assigned to the training cohort (n=78) and validation cohort (n=53) in a 6:4 ratio.

Circular RNAs (circRNAs) are known to play a crucial role in the progression of atherosclerosis (AS). In this study, we aim to explore the function of oxidized low-density lipoprotein (ox-LDL)-induced macrophage-derived exosomal circ_100696 in AS.THP-1 macrophages were induced by ox-LDL to mimic AS cell model.

Background: Circular RNAs (circRNAs) have shown important regulatory roles in cardiovascular diseases, including atherosclerosis (AS). However, the role and mechanism of circ_0026218 in AS remain unclear.

Methods: The cell model of AS in vitro was established by stimulating human umbilical vein endothelial cells (HUVECs) with oxidized low-density lipoprotein (ox-LDL).

Purpose: The aim of this study was to explore the improved image quality of the portal vein using the contrast-enhancement boost (CE-boost) technique for the improved visibility of abdominal-enhanced computed tomography (CT) scans in clinical practice.

Methods: This retrospective study included 50 patients in Group A who underwent routine abdominal-enhanced CT and 50 patients in Group B who underwent abdominal computed tomography angiography (CTA) with matched body mass index, age, and sex. Images in Group A were postprocessed with the CE-boost technique for further enhanced visibility of the portal vein.

Purpose: The objective of this study was to correlate multidetector computed tomography (MDCT) findings in hepatic alveolar echinococcosis (HAE) with intraoperative and postoperative histopathological results to identify reliable MDCT criteria for the diagnosis of HAE venous invasion.

Methods: A total of 136 HAE patients who underwent CT examination were included in this study. The lesion-vessel contact angle, irregular wall, lumen stenosis and occlusion were evaluated.

The degradation of methylene blue is a critical procedure in its wastewater remediation and thus has inspired wide catalysis research with semiconductors such as titanium dioxide (TiO) and rare metals such as gold (Au). In this study, we report bacterial cells assisting biosynthesis for Au@TiO as an efficient catalyst for the catalytic degradation of methylene blue. Multiple complementary characterization for bio-Au@TiO evidenced the evenly distributed Au nanoparticles (NPs) on the bio-TiO layers.

A unique porous TiO with CoO nanoparticles anchored in (CoO@TiO) is prepared by a dual-templating method for promoting electromagnetic microwave absorption (EMA). The as-prepared CoO@TiO possesses a three-dimensional (3D) ordered macroporous TiO skeleton and plenty of mesopores, as well as small CoO nanoparticles that coexisted in the macropore walls of the TiO skeleton. The introduction of CoO can increase the magnetic loss as well as suppress impedance mismatch, resulting in the regulation of the EMA performance.

Background: To evaluate the role of radiomics based on magnetic resonance imaging (MRI) in the biological activity of hepatic alveolar echinococcosis (HAE).

Methods: In this study, 90 active and 46 inactive cases of HAE patients were analyzed retrospectively. All the subjects underwent MRI and positron emission tomography computed tomography (PET-CT) before surgery.

Article Synopsis
  • - A survey analyzing 578 topsoil samples in Wuqing District, Tianjin identified concentrations of eight heavy metals: Cd, Pb, Cu, Zn, Cr, Ni, As, and Hg, with most levels exceeding natural-background values.
  • - Different sources contributed to heavy metal presence: natural sources for As, Ni, and Cr; a mix of natural materials and sewage for Cu and Zn; Pb and Cd mainly from non-point source pollution; and Hg predominantly from sewage irrigation.
  • - The study utilized various analytical methods, including descriptive statistics and geostatistical analysis, demonstrating that combining different technologies effectively identifies the sources of heavy metal pollution.

Objective: To analyse the results of posterior cruciate ligament-retained mobile-bearing total knee arthroplasty (TKA) in treatment of rheumatoid arthritis (RA) and to solve the problems often encountered during surgery.

Methods: From February 1999 to August 2005, the clinical data from 73 patients with RA undergoing TKA were analysed retrospectively. In 73 patients, 38 patients were treated with posterior cruciate ligament-retained mobile-bearing prosthesis (group A), while 35 patients were treated with posterior stabilized fixed-bearing prosthesis (group B).

Objective: To evaluate the usefulness of minimal incision technique in total knee arthroplasty (TKA) by comparing the early complications after minimal incision TKA and those after traditional incision.

Methods: From May 2004 to July 2005, 38 patients (46 knees) underwent TKA using the minimal incision technique (minimal incision group), and 43 patients (54 knees) underwent TKA using the traditional incision technique at the same period (traditional incision group). The minimal incision group included 12 male patients (12 knees) and 26 female patients (34 knees), and their ages ranged from 52 to 76 years.
