Comparative Evaluation of CEUS and CECT in the Detection of Liver Metastases of Middle and Low Rectal Cancer.

Objective: To explore the imaging manifestations and clinical application value of contrast-enhanced ultrasound (CEUS) in liver metastases of middle and low rectal cancer by performing CEUS in patients. Additionally, we compared the results of CEUS with those of abdominal contrast-enhanced computed tomography (CECT) to assess the reliability of diagnosing liver metastases in patients with middle and low rectal cancer.

Methods: Hepatic CEUS was performed in 1095 patients with middle and low rectal cancer, and all patients underwent abdominal CECT examinations to determine the presence or absence of liver metastases.

Numerical experiment of phase-matched ion-based high-order harmonic generation in the water-window x-ray spectral region via electromagnetic envelope equation.

We present a phase-matching scheme for efficient high-order harmonic generation in the water-window x-ray spectral region using a 405-nm driving pulse. A high-intensity pulse (∼10 W/cm) is used to produce He ions as the target medium, increasing the cutoff photon energy to the water-window x-ray spectral region. By adjusting the driving pulse divergence, the positive dipole phase variation balances the negative plasma dispersion and geometrical phase shift, achieving phase matching.

The Diagnostic Value of Musculoskeletal Ultrasound in the Quantitative Evaluation of Skeletal Muscle in Chronic Thyrotoxic Myopathy: A Single-Center Study in China.

Objective: This study aimed to evaluate the quadriceps femoris in patients with chronic thyrotoxic myopathy (CTM) using musculoskeletal ultrasound and to explore its practical clinical value for the diagnosis of CTM.

Methods: A total of 241 subjects recruited from the First Affiliated Hospital of Guangxi Medical University were surveyed for detailed medical history and underwent grip strength tests, fixed-distance walking, and quadriceps femoris ultrasound examinations. Differences in muscle parameters between the CTM, non-CTM, and healthy groups were analyzed.

The correlation between time-intensity curve parameters of transrectal contrast-enhanced ultrasound and pathological prognostic factors in rectal adenocarcinoma.

Aims: To investigate the correlation between time-intensity curve (TIC) parameters obtained from transrectal contrast-enhanced ultrasound (TR-CEUS) and important pathological prognostic factors in rectal adenocarcinoma.

Material And Methods:  We retrospectively included 477 patients with pathologically confirmed rectal adenocarcinoma. TIC parameters were derived from preoperative dynamic TR-CEUS images.

Assessment of the Effects of Sphingosine Kinase 1/Sphingosine-1-Phosphate on Microangiogenesis at Rat Myofascial Trigger Points Using Contrast-Enhanced Ultrasonography.

Purpose: Few studies have assessed the effects of sphingosine kinase 1/sphingosine-1-phosphate (SPHK1/S1P) on microangiogenesis at rat myofascial trigger points (MTrPs) using contrast-enhanced ultrasonography (CEUS). This study aimed to address these deficiencies. Here, we investigated the effects of SPHK1/S1P on MTrP microangiogenesis and the value of CEUS in evaluating these effects.

Contrast Enhanced Ultrasonography of Kidney in Chronic Intermittent Hypoxia Rat Model.

Objectives: The objective of our study was to assess the ability of contrast-enhanced ultrasound (CEUS) in evaluating renal microperfusion in an animal model.

Methods: Twenty Sprague-Dawley rats were subdivided into two groups: the normal and chronic intermittent hypoxia (CIH) groups. In the CIH model, 10 Sprague-Dawley rats were exposed to CIH for 8 weeks to mimic obstructive sleep apnea (OSA).

Ion-based high-order harmonic generation from water window to keV region with a transverse disruptive pulse for quasi-phase-matching.

A scheme for ion-based high-harmonic generation from water window to keV x-ray is investigated. He ions with 54.42-eV ionization potential extend the harmonic cutoff energy to 1 keV.

The Protective Effects of Sulforaphane on High-Fat Diet-Induced Obesity in Mice Through Browning of White Fat.

Sulforaphane (SFN), an isothiocyanate naturally occurring in cruciferous vegetables, is a potent indirect antioxidant and a promising agent for the control of metabolic disorder disease. The glucose intolerance and adipogenesis induced by diet in rats was inhibited by SFN. Strategies aimed at induction of brown adipose tissue (BAT) could be a potentially useful way to against obesity.

Sulforaphane Inhibits Osteoclastogenesis via Suppression of the Autophagic Pathway.

Previous studies have demonstrated that sulforaphane (SFN) is a promising agent against osteoclastic bone destruction. However, the mechanism underlying its anti-osteoclastogenic activity is still unclear. Herein, for the first time, we explored the potential role of autophagy in SFN-mediated anti-osteoclastogenesis in vitro and in vivo.

Sonographic Assessment of Oropharynx Movement During Deep Breathing.

To investigate the feasibility of ultrasonography in detecting the oropharynx movement during deep breathing and to quantitatively analyze oropharynx airway lumen changes during deep breathing. The motions of oropharynx were monitored, and sonographic measurements of airway lumen were obtained during deep breathing in 448 healthy volunteers. Adequate visualization of oropharynx movement was obtained on all healthy volunteers.

Contrast-enhanced Ultrasound in evaluating of angiogenesis and tumor staging of nasopharyngeal carcinoma in nude mice.

Objective: To explore the use of Contrast-enhanced Ultrasound (CEUS) in evaluating angiogenesis in a xenograft nasopharyngeal carcinoma (NPC) model in nude mice and the evolution of CEUS parameters according to the growth of NPC.

Methods: Nude mice were divided into three groups according to experiments conducted at various times from tumor implantation (8 mice/group; group A: 4 weeks from implantation; group B:6 weeks from implantation; group C:8 weeks from implantation). CNE-2 cells were transplanted in 24 nude mice and CEUS evaluations of the tumors were performed at 4, 6 or 8 weeks from implantation.

MG53 Inhibits the Progression of Tongue Cancer Cells through Regulating PI3K-AKT Signaling Pathway: Evidence from 3D Cell Culture and Animal Model.

MG53 is transcriptionally activated by the IRS-1/PI3K/AKT signal pathway, which is closely related with oncogenesis of several tumors. Here, the role of MG53 in the tumorigenesis of tongue cancer is analyzed in vitro and in vivo. The stable MG53 overexpression/knockdown SCC9 and SCC25 cells are constructed through retrovirus infection.
