Accelerated Multi-b-Value DWI Using Deep Learning Reconstruction: Image Quality Improvement and Microvascular Invasion Prediction in BCLC Stage A Hepatocellular Carcinoma.

Rationale And Objectives: To investigate the effect of accelerated deep-learning (DL) multi-b-value DWI (Mb-DWI) on acquisition time, image quality, and predictive ability of microvascular invasion (MVI) in BCLC stage A hepatocellular carcinoma (HCC), compared to standard Mb-DWI.

Methods: Patients who underwent liver MRI were prospectively collected. Subjective image quality, signal-to-noise ratio (SNR), lesion contrast-to-noise ratio (CNR), and Mb-DWI-derived parameters from various models (mono-exponential model, intravoxel incoherent motion, diffusion kurtosis imaging, and stretched exponential model) were calculated and compared between the two sequences.

Mitigating the skin phototoxicity of sonodynamic therapy via singlet oxygen-consuming metal-organic frameworks.

Sonodynamic anti-cancer therapy relies on the highly active singlet oxygen to induce potent cell death. However, the non-specific biodistribution of sonosensitizers post systemic administration results in a significant accumulation in the skin, and hence the daylight-induced phototoxicity. Here, we report a smart metal-organic framework-based nanocarrier with titanium dioxide (TiO) as the sonosensitizer for reduced phototoxicity in the skin.

Redox-manipulating nanocarriers for anticancer drug delivery: a systematic review.

Spatiotemporally controlled cargo release is a key advantage of nanocarriers in anti-tumor therapy. Various external or internal stimuli-responsive nanomedicines have been reported for their ability to increase drug levels at the diseased site and enhance therapeutic efficacy through a triggered release mechanism. Redox-manipulating nanocarriers, by exploiting the redox imbalances in tumor tissues, can achieve precise drug release, enhancing therapeutic efficacy while minimizing damage to healthy cells.

Energy Metabolism Enhance Perylenequinone Biosynthesis in sp. Slf14 through Promoting Mitochondrial ROS Accumulation.

Perylenequinones (PQs) are important natural compounds that have been extensively utilized in recent years as agents for antimicrobial, anticancer, and antiviral photodynamic therapies.

Hypoxia-responsive micelles deprive cofactor of stearoyl-CoA desaturase-1 and sensitize ferroptotic ovarian cancer therapy.

Ferroptosis has been recognized as a promising therapeutic strategy for cancer due to its unique mechanism of action. However, the upregulation of stearoyl-CoA desaturase 1 (SCD1) in ovarian cancer leads to resistance to ferroptotic therapy. Zinc ion (Zn) serves as the cofactor of SCD1.

SOX11 as a prognostic biomarker linked to m6A modification and immune infiltration in renal clear cell carcinoma.

Background: The prognosis for patients with kidney renal clear cell carcinoma (KIRC) remains unfavorable, and the understanding of SRY-box transcription factor 11 (SOX11) in KIRC is still limited. The purpose of this paper is to explore the role of SOX11 in the prognosis of KIRC.

Methods: We analyzed SOX11 expression in KIRC and adjacent normal tissues using The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) databases.

Partial discharge detection, diagnosis, and location technology based on a novel transient earth voltage-ultrasonic integrated sensor used for switchgear equipment.

Medium-voltage (MV) switchgear and gas insulated switchgear (GIS) are essential components of power-grid systems. Their safe operation is crucial for the electricity consumption of users. However, insulation faults often occur during the operation of MV switchgear and GIS because of pollution, humidity, heat, mechanical shock, and other factors.

Efficacy analysis of mechanical thrombectomy combined with prolonged mild hypothermia in the treatment of acute middle cerebral artery occlusion: a single-center retrospective cohort study.

Objective: To determine the efficacy of mechanical thrombectomy combined with prolonged mild hypothermia compared with conventional treatment in managing acute middle cerebral artery occlusion, and to explore whether extending the duration of hypothermia can improve neurological function.

Method: From 2018 to June 2023, a retrospective analysis was conducted on 45 patients with acute middle cerebral artery occlusion treated at the NICU of Suzhou Kowloon Hospital, affiliated with Shanghai Jiao Tong University School of Medicine. After thrombectomy, patients were admitted to the neurological intensive care unit (NICU) for targeted temperature management.

PAS-7 is Superior to APAIS for Assessing Preoperative Anxiety in the Chinese Population.

Purpose: The purpose of this study was to analyze the reliability and validity of the Perioperative Anxiety Scale-7 (PAS-7), which was created by Chinese medical professionals, by using the State-Trait Anxiety Scale (STAI-S) as the standard for the diagnosis of preoperative anxiety, and to compare whether there is a difference between the PAS-7 and the Amsterdam Preoperative Anxiety and Information Scale (APAIS) in the diagnosis of preoperative anxiety in the Chinese population.

Design: This study was an observational study.

Methods: The PAS-7, APAIS, and STAI-S were all completed the day before surgery.

Bi-regional dynamic contrast-enhanced MRI for prediction of microvascular invasion in solitary BCLC stage A hepatocellular carcinoma.

Objectives: To construct a combined model based on bi-regional quantitative dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI), as well as clinical-radiological (CR) features for predicting microvascular invasion (MVI) in solitary Barcelona Clinic Liver Cancer (BCLC) stage A hepatocellular carcinoma (HCC), and to assess its ability for stratifying the risk of recurrence after hepatectomy.

Information infrastructure and corporate green innovation quality incentive.

We use a sample of Chinese firms from 2006 to 2020 to investigate the effect of information infrastructure on the quality of green innovation. Findings show that information infrastructure significantly improves corporate green innovation quality, and information infrastructure improves the pricing efficiency, improves valuation levels, accelerates the flow of innovation resources, and induces the growth effect of corporate innovation resources. Furthermore, we find that executive salary incentives, internal control quality, and market-oriented environmental regulation have adaptive incentives for information infrastructure to improve the quality of green innovation.
