  • * A new magnetic resonance imaging (MRI) technique was used in this study to track the distribution of functionalized polystyrene microplastics (PS-MPs) in the liver of living organisms over 21 days.
  • * The study found severe toxic effects from PS-MPs on liver tissue, including cell death and inflammation, with more harmful effects observed from positively charged MPs, highlighting their disturbance of key liver metabolic processes.

Objective: This study aimed to investigate the impact of puerarin early intervention on growth parameters and Hepatic Fat Signal Fraction (HFF) quantification in Intrauterine Growth Restricted(IUGR)rats through Proton Magnetic resonance spectroscopy (1H-MRS).

Methods: Pregnant rats were divided into three groups: control, IUGR with puerarin treatment, and IUGR without treatment. The treatment and nontreatment groups were received a low-protein diet during pregnancy, while the control group received a normal diet.

Objectives: Magnetic resonance diffusion-weighted imaging (DWI) has important clinical value in diagnosis and curative effect evaluation on endometrial carcinoma. How to improve the detection rate of endometrial small lesions by DWI is the research focus of MRI technology. This study aims to analyze the image quality of small field MRI ZOOMit-DWI sequence and conventional single-shot echo-planar imaging (SS-EPI) DWI sequence in the scanning of endometrial carcinoma, and to explore the clinical value of ZOOMit-DWI sequence.

Introduction: This study aimed to investigate the possible associations between problematic smartphone use and brain functions in terms of both static and dynamic functional connectivity patterns.

Materials And Methods: Resting-state functional magnetic resonance imaging data were scanned from 53 young healthy adults, all of whom completed the Short Version of the Smartphone Addiction Scale (SAS-SV) to assess their problematic smartphone use severity. Both static and dynamic functional brain network measures were evaluated for each participant.

Objectives: To study the correlation of the expression of in visceral adipose tissue and in liver tissue with hepatic fat content in rats with intrauterine growth retardation (IUGR).

Methods: Pregnant rats were given a low-protein (10% protein) diet during pregnancy to establish a model of IUGR in neonatal rats. The pregnant rats in the control group were given a normal-protein (21% protein) diet during pregnancy.

In this study, we compared different anesthesia and operation methods for modeling VX2 hepatocarcinoma in rabbits. Forty New Zealand white rabbits were randomly divided into three groups: A, B, and C. Group A underwent ultrasound-guided implantation and intravenous anesthesia; Group B underwent ultrasound-guided implantation and inhalation anesthesia; Group C underwent laparotomy implantation and intravenous anesthesia.

Proton magnetic resonance spectroscopy (H-MRS) measurement of hepatic fat content in intrauterine growth restriction rats has rarely been reported. This study was to explore the association of peroxisome proliferator-activated receptor alpha and gamma (PPARα and PPARγ) expression with H-MRS quantified hepatic fat content in offspring of rats that experienced intrauterine growth restriction (IUGR). IUGR was established by feeding a low-protein diet to female rats during pregnancy.

Objective: Proton magnetic resonance spectroscopy (H-MRS) measurement of liver metabolism in intrauterine growth restriction rats has seldom been reported. This study investigated the application of H-MRS in assessing liver metabolism in newborn pups that experienced intrauterine growth restriction.

Methods: Intra-uterine growth restriction was established by feeding rats low-protein diets during pregnancy.

The present study aimed to assess the in vitro and in vivo magnetic resonance imaging (MRI) features of chlorotoxin (CTX)-conjugated superparamagnetic iron oxide (SPIO) nanoprobes. CTX-conjugated nanoprobes were composed of SPIO coated with polyethylene glycol (PEG) and conjugated with CTX. The nanoprobes were termed SPIO-PEG-CTX.

Purpose: To investigate the changes to diffusion-weighted imaging (DWI) correlated with histopathology after neoadjuvant chemotherapy (NACT) in patients with locally advanced cervical cancer (LACC).

Materials And Methods: Thirty-three patients with LACC were examined with 3T magnetic resonance imaging (MRI) with DWI and apparent diffusion coefficient (ADC) maps. MRIs were performed for each patient at three timepoints: before the first NACT, 2 weeks after the first NACT, and 2 weeks after the second NACT.

Purpose: To compare the characteristics of magnetic resonance perfusion-weighted imaging (MRPWI) scans before and after transcatheter arterial chemoembolization (TACE) treatment of hepatocellular carcinoma (HCC) and to apply MRPWI in evaluating the therapeutic effect of TACE and prognosis of HCC.

Materials And Methods: Thirty-five patients with HCC undergoing their first TACE treatment were enrolled in this study. T2WI, T1WI, and PWI of MRI were performed 24-48 h before TACE and 48-168 h after TACE.

Objective: The objective of this study was to investigate whether magnetic resonance diffusion-weighted imaging (DWI) of locally advanced cervical cancer (LACC) both in the sagittal and axial planes could be used to assess the response of LACC to neoadjuvant chemotherapy (NACT).

Methods: Thirty women with LACC received conventional magnetic resonance imaging and DWI at 3 different times (before NACT, 2 weeks after the first NACT, and 2 weeks after the second NACT). Treatment response was determined according to the change in tumor size 2 weeks after the second NACT, and they were classified as the effective group and the ineffective group.

A short half-life and low levels of growth factors in an injured microenvironment necessitates the sustainable delivery of growth factors and stem cells to augment the regeneration of injured tissues. Our aim was to investigate the ability of VEGF(165) expressing bone marrow mesenchymal stem cells (BMMSCs) to differentiate into hepatocytes when cultured with hepatocyte growth factor (HGF) and epidermal growth factor (EGF) in vitro. We isolated, cultured and identified rabbit BMMSCs, then electroporated the BMMSCs with VEGF(165)-pCMV6-AC-GFP plasmid.
