Measurement and analysis of photoacoustic pressure induced by weak microsecond pulsed light.

The photoacoustic effect (PAE) of weak microsecond pulsed light (WMPL) has immense potential for application to biomedical engineering. However, practical measurements and theoretical analysis of the photoacoustic pressure of WMPL are lacking. Hence, we constructed a WMPL photoacoustic pressure measurement system using an electret piezoelectric sensor and multi-wavelength parameter-adjustable pulsed light generator.

Unraveling the mechanisms of anammox coupled process with thiosulfate-driven denitrification: Community succession and substrate competition.

Thiosulfate-driven denitrification coupled with anammox (TDDA) has garnered interest for its efficient and innovative nitrogen removal capabilities. However, the intricate dynamics of the internal microbial community and the specific characteristics of anaerobic ammonium oxidizing bacteria (AnAOB) remain incompletely understood. This study combines experimental methods with density functional theory (DFT) calculations to address these gaps.

Objective: To investigate the failure patterns of recurrent nasopharyngeal carcinoma (NPC), especially to identify the relationship between the recurrent-prone anatomic structures and the tumor regression sites after the introduction of chemotherapy (IC).

Method: A cohort of 1121 non-metastatic patients with NPC was retrospectively enrolled. The pretreatment and recurrent images of each patient were registered to the planning CT.

Production cross sections of Rh and Ag in proton bombed Pb target with 400 MeV energy.

The accelerator-driven subcritical system (ADS) is a competitive option for next-generation nuclear energy systems. Production cross sections of long-lived residual radioactive nuclides in a proton-nuclide reaction are basic quantities for the calculation of accumulated radioactivity in the use of ADS systems. This work presents the production cross sections of Rh and Ag in a natural lead (Pb) target activated by 400 MeV protons.

Coordinating principal-agent and incentive strategy of cold chain logistics service in fresh food supply chain.

With the increasing production and circulation of fresh food, society's requirements for product quality have also increased. Currently, upstream and downstream enterprises in the fresh food supply chain tend to delegate the cold chain transportation of fresh food to third-party cold chain logistics (CCL) service providers who offer more professional integrated preservation services. This study adopts coordination theory to research the delegation, coordination, and incentive strategies between a Fresh Food Producer, Distributor, and CCL Service Provider.

Exploring the mechanism of Cinnamomi Cortex against morphine addiction using network pharmacology and molecular docking analyses.

Cinnamomi Cortex is a commonly used herb with a variety of pharmacological effects. We investigated the molecular mechanisms by which Cinnamomi Cortex antagonises morphine addiction (MA) using network pharmacology and molecular docking techniques in a morphine-dependent rat withdrawal model. The antagonistic effect of Cinnamomi Cortex was observed by inducing withdrawal symptoms in morphine-dependent rats through a dose-escalation method.

Value of Combined Optical Coherence Tomography and Optical Flow Ratio Measurements After Percutaneous Coronary Intervention.

Background: Optical flow ratio (OFR) is a novel computational fractional flow reserve derived from optical coherence tomography (OCT). However, the impact of combining post-stenting morphology (OCT) and physiology (OFR) remains largely unknown.

Methods: OCT and OFR were analysed at an independent core laboratory.

Placental ischemia-upregulated angiotensin II type 1 receptor in hypothalamic paraventricular nucleus contributes to hypertension in rat.

Preeclampsia (PE) is associated with increased angiotensin II sensitivity and poor neurological outcomes marked by temporal loss of neural control of blood pressure. Yet the role of centrally expressed angiotensin II type 1 receptor (AT1R) within the paraventricular nucleus of the hypothalamus (PVN) in the PE model is not understood. In a PE rat model with reduced placental perfusion pressure (RUPP) induced on gestational day 14 (GD14), the PVN expression and cellular localization of AT1R were assessed using immunofluorescence and western blotting.

Clinical analysis of 10 cases with subcutaneous panniculitis-like T-cell lymphoma and tissue AURKA expression.

Background: Due to its rarity, subcutaneous panniculitis-like T-cell lymphoma (SPTCL) is often misdiagnosed as benign panniculitis, and there are no standardized treatment guidelines for SPTCL. Aurora kinase A (AURKA) plays a regulatory role in both mitosis and meiosis. Cells treated with an AURKA inhibitor showed severe mitotic delay, which triggered apoptosis.

Five-year follow-up of OCT-guided percutaneous coronary intervention in patients with ST-segment elevation myocardial infarction.

Background: Compared with intravascular ultrasound guidance, there is limited evidence for optical coherence tomography (OCT) guidance during primary percutaneous coronary intervention (pPCI) in ST-segment elevation myocardial infarction (STEMI) patients.

Aims: We investigated the role of OCT in guiding a reperfusion strategy and improving the long-term prognosis of STEMI patients.

Methods: All patients who were diagnosed with STEMI and who underwent pPCI between January 2017 and December 2020 were enrolled and divided into OCT-guided versus angiography-guided cohorts.
