In this study, we found that pancreatic progenitor cell differentiation and proliferation factor (PPDPF) is upregulated in ESCC and its expression level is associated with lymph node metastasis. PPDPF was found to promote tumorigenesis, lymph node metastasis and distal metastasis of ESCC cells.

Understanding the correlation between crystal structure variation and photoluminescence (PL) quenching is significant to achieve anti-thermal quenching (anti-TQ) phosphors. Herein, we unveil a universal principle governing switchable TQ and anti-TQ behaviors in zero-dimensional (0D) organic-inorganic hybrid manganese bromides.

Disruption of the blood-brain barrier (BBB) is considered one of the key mechanisms underlying POD. Therefore, the present study aimed to investigate the effects of different BBB permeability alteration pathways on POD in mice of various ages.

Monitoring peripheral blood lymphocyte subsets level (PBLSL) can predict treatment response and prognosis with immune checkpoint inhibitors. This study investigated the heterogeneity of PBLSL in response to chemoradiotherapy (CRT) or combined with immunotherapy (CRIT) in advanced lung cancer patients.

However, it also has great development potential in the conversion of space light to guided waves. In this paper, we propose a compact structure consisting of silicon nanoantennas and waveguides for controlling the conversion of linearly polarized light in free space into guided waves and propagating along the waveguide.

Biomarkers associated with potential therapeutic effects were also explored.
Methods: Patients with previously untreated ES-SCLC were enrolled at Shandong Cancer Hospital and Institute (Jinan, China).
This article analyzes the geographical distribution of poets in Song China based on Complete Song Poetry (Quansongshi), which includes poems from over 9000 poets, with 6056 of them having clear native place. Visualization strategy is used to present the geographical distribution of these 6056 poets, and its formation factors are also analyzed. The results reveal that majority of the poets come from Zhejiang, Henan and Sichuan provinces, with Guangdong province also exceeding a hundred poets despite its remote location.

As a free radical and endogenous effector molecule, mammalian endogenous nitric oxide (NO) is mainly derived from nitric oxide synthase (NOS) via L-arginine. NO participates in normal physiological reactions and provides immune responses to prevent the invasion of foreign bacteria. However, NO also has complex and contradictory biological effects.

Addressing the shortcomings of traditional methods, such as poor adaptability and low sensitivity in optical and visual tube detection, and aiming to reduce the computational and detection time costs introduced by neural networks, this paper proposes a lightweight yarn spool detection model based on YOLOv8. The model utilizes Darknet-53 as the backbone network, and due to the dense spatial distribution of yarn spool targets, it incorporates large selective kernel units to enhance the recognition and positioning of dense targets.
