Objective: The interaction between T cells, particularly naïve CD4 T cells (CD4Tn), and colorectal cancer (CRC) is highly complex. CD4Tn play a crucial role in modulating immune responses within the tumor microenvironment, yet the precise mechanisms by which they influence tumor progression remain elusive. This study aims to explore the relationship between CRC and CD4Tn, identify biomarkers and therapeutic targets, and focus on the role of CD4Tn in shaping the immune environment of CRC.

Herein, an ER-targeting ˙OH fluorescent probe (ER-OH) has been developed, which showed a large fluorescence increase at 645 nm in response to ˙OH. ER-OH was applied to monitor ferroptosis by fluorescence imaging, revealing a significant increase of the ˙OH level in the ER during this process.

Some spirochetes are important human pathogens that utilize periplasmic flagella to achieve motility and host infection. The motors that drive the rotation of periplasmic flagella have a unique spirochete-specific feature, termed the collar, crucial for the flat-wave morphology and motility of the Lyme disease spirochete Borrelia burgdorferi.

A total of 46 patients were enrolled, receiving pyrotinib orally once daily and fulvestrant intramuscularly on days 1 and 15 of cycle 1, followed by monthly doses on day 1. The primary endpoint was progression-free survival (PFS), while secondary endpoints included overall survival (OS), objective response rate (ORR), disease control rate (DCR), and safety.

However, the comparison between the efficacy of CDK4/6i has been poorly explored before. Moreover, it remains unclear about the optimal choice of CDK4/6i in the first-line treatment for HR+/HER2- MBC patients in Asian, especially Chinese populations.

To obtain the backfat thickness of sows automatically, a backfat thickness estimation method based on machine vision is proposed. First, the backfat thickness values and 3D images of the buttocks of 154 Landrace-Yorkshire crossbred sows were obtained using a veterinary ultrasound backfat meter and Azure Kinect DK camera.

While activating pyroptosis represents a promising therapeutic strategy for cancer, the regulatory mechanisms governing GSDMD expression during cell death remain poorly understood. In this study, we identified METTL3 as a negative regulator of GSDMD-mediated pyroptosis, with high expression in breast cancer (BC) cells.

Objective: We aimed to compare the immune response to different viral pathogens to understand the connection between infections and cytokine storm syndromes.
Methods: We recruited children who sought care at the emergency department with fever for ≥3 days.
Objective: To characterize the inflammatory proteome in both serum and synovial fluid (SF) of patients with gout, in comparison to healthy controls and individuals with osteoarthritis (OA), by utilizing a high-quality, high-throughput proteomic analysis technique.
Methods: Using the Olink Target 48 Inflammation panel, we measured serum concentrations of 45 inflammatory proteins in gout, OA, and healthy controls. We analyzed protein levels in SF samples from gout and OA, performed ROC curve analyses to identify diagnostic biomarkers, evaluate efficacy, and set cut-off values.
Objective: The involvement of immune cells in colorectal cancer (CRC) and their interplay with metabolic disorders are yet to be fully elucidated. This study examines how peripheral immune cells, inferred genetically, affect CRC and investigates the intermediary roles of metabolites.
Methods: We employed a two-sample bidirectional Mendelian randomization (MR) approach to assess the causal influence of immune cells on CRC.
Purpose: The study aimed to develop a nomogram model for individual prognosis prediction in patients with hormone receptors positive (HR+) mucinous breast carcinoma (MBC) and assess the value of neoadjuvant chemotherapy (NAC) in this context.
Methods: A total of 6,850 HR+ MBC patients from the SEER database were identified and randomly (in a 7:3 ratio) divided into training cohorts and internal validation cohorts. 77 patients were enrolled from the Chongqing University Cancer Hospital as the external validation cohort.

As the thickness of an ultra-thin flattened heat pipe (UTHP) decreases, the fabrication difficulty increases exponentially, and the thermal performance deteriorates rapidly. In this study, three types of composite wicks were developed for UTHPs with a 0.6 mm thickness: copper foam and mesh wick (CFMW), two layers of different mesh wick (TDMW), and three layers of the same mesh wick (TSMW).

During the high-temperature selenization process of CZTSSe, the diffusion of various elements and chemical reactions significantly influence defect formation. In this study, a NaOH-Se intermediate layer introduced at the back interface can optimize CuZnSnS (CZTS)precursor films and subsequently adjust the Se and alkali metal content to favor grain growth during selenization.
