Introduction: Colonic manometry (CM) is a diagnostic procedure used to evaluate pediatric patients with refractory constipation, fecal incontinence, Hirschsprung disease, and pediatric intestinal pseudo-obstruction. Pan-colonic high-amplitude propagated contractions (HAPCs), measured by CM, reflect an intact neuromuscular function of the colon. Current guidelines recommend starting CM with fasting recording for 1-2 h, but no prior evaluation has determined the diagnostic yield of the fasting phase.

The research aims to investigate the mechanical response of footfalls at different velocities to understand the mechanism of heel injury and provide a scientific basis for the prevention and treatment of heel fractures. A three-dimensional solid model of foot drop was constructed using anatomical structures segmented from medical CT scans, including bone, cartilage, ligaments, plantar fascia, and soft tissues, and the impact velocities of the foot were set to be 2 m/s, 4 m/s, 6 m/s, 8 m/s, and 10 m/s. Explicit kinetic analysis methods were used to investigate the mechanical response of the foot landing with different speeds to explore the damage mechanism of heel bone at different impact velocities.

Objective: This study compared the fracture load, stress distribution, and survival probability under cyclic loading of extensively restored teeth treated with multisonic irrigation with those treated with conventional instrumentation, with or without a post.

Methods: Mesial-occlusal-distal cavities were prepared in 30 human mandibular premolars. The teeth were randomly divided into 3 groups of 10 based on the endodontic and restorative procedures: (1) Root canal treatment (RCT) followed by resin composite restoration (control group), (2) RCT followed by a glass fiber post restoration (conventional group), and (3) minimal instrumentation plus multisonic irrigation followed by resin composite restoration (GW group).

Di-(2-ethylhexyl) phthalate (DEHP) is widely utilized as a plasticizer in industrial manufacturing to enhance the durability and flexibility of plastics. Studies have depicted that DEHP exposure may be associated with multiple cancers, including colorectal, liver and prostate cancer. However, the effects and underlying mechanisms of DEHP on bladder cancer progression remain unspecific.

Rationale And Objectives: To assess the predictive value of MRI-based radiomics of periprostatic fat (PPF) and tumor lesions for predicting Gleason score (GS) upgrading from biopsy to radical prostatectomy (RP) in prostate cancer (PCa).

Methods: A total of 314 patients with pathologically confirmed prostate cancer (PCa) after radical prostatectomy (RP) were included in the study. The patients were randomly assigned to the training cohort (n = 157) and the validating cohort (n = 157) in a 1:1 ratio.

Mechanical ventilation (MV) remains a cornerstone of critical care; however, its prolonged application can exacerbate lung injury, leading to ventilator-induced lung injury (VILI). Although previous studies have implicated ferroptosis in the pathogenesis of VILI, the underlying mechanisms remain unclear. This study investigated the roles of ferritinophagy in ferroptosis subsequent to VILI.

Background: Tumor-specific antigens play an important role in dendritic cell (DC)-based immunotherapy. The acquisition of tumor-specific antigens, which are essential for DC-based immunotherapy, poses a significant challenge. This study aimed to explore the efficacy of hypoxia inducible factor-1α (HIF-1α) overexpression tumor antigens in DC-based immunotherapy.

Introduction: Lung injury, a common complication of sepsis, arises from elevated reactive oxygen species (ROS), mitochondrial dysfunction, and cell death driven by inflammation. In this study, a novel class of ultrasmall nanoparticles (CuO USNPs) was developed to address sepsis-induced lung injury (SILI).

Methods: The synthesized nanoparticles were thoroughly characterized to assess their properties.

Examining whether nitrogen (N) enrichment promotes secondary tree growth in both young (YF) and old-growth forests (OF) is crucial. This will help determine how N addition influences plant carbon sequestration across successional phases in temperate forests. We conducted an eight-year N addition experiment (0, 25, 50, 75 kg N ha yr) in YF and OF in northeast China to investigate the effects of enhanced in situ N deposition on tree growth.

Background: Environmental factors have been identified as primary risk factors for type 2 diabetes mellitus (T2DM). However, studies on the association between environmental factors and T2DM have mainly focused on morbidity and mortality, which do not fully reflect the disease burden stemming from air pollution. Therefore, we aimed to evaluate the correlation between air pollution and T2DM, including hospital length of stay (LOS) and costs.

Objective: We aim to investigate whether Coronavirus disease 2019 (COVID-19) worsens chronic hepatitis B virus(HBV)infection and explore the incidence of long COVID symptoms in patients with chronic hepatitis B virus infection.

Methods: Patients with chronic HBV infection and COVID-19 patients attending the hepatitis clinic or fever clinic were included in the study. Clinical manifestations of COVID-19 and information about long COVID were collected for all patients.

Whether an increased genetic risk of steatotic liver disease (SLD) can be offset by maintaining a healthy weight remains unknown. We aimed to clarify the associations among the body mass index (BMI) and its change patterns with SLD and assess whether genetic susceptibility can modify these associations in Chinese people. A total of 10,091 and 6124 participants from the Health Omics Preventive Examination (HOPE) Program were enrolled in cross-sectional and follow-up analyses, respectively.

Background: Bioelectrical impedance is used clinically to assess body composition. To determine true (rather than chance/measurement error) change in bioelectrical impedance analysis measurements over time, it is necessary to know their least significant change. Least significant change represents values exceeding the 95% prediction interval of the precision error of repeat measurements.

Article Synopsis
  • This study examined how cullin-1 (CUL1) affects chronic obstructive pulmonary disease (COPD) through experiments on both mouse models and cell cultures.
  • CUL1 levels were found to be lower in COPD, but increasing CUL1 helped improve cell health by promoting cell survival, reducing cell death, and decreasing inflammation and oxidative stress.
  • The protective effects of CUL1 were linked to its ability to inhibit the p53 signaling pathway, which plays a role in the disease's progression.

Purpose: In preimplantation genetic testing for monogenic/single gene disorders (PGT-M) cycles, direct detection of the pathogenic mutation combined with indirect haplotype analysis are recommended to achieve accurate diagnosis. However, it poses a challenge to conduct haplotype analysis for patients carried de novo pathogenetic mutations or without no identified haplotype in families. Herein, the strategy of affected-embryo-based haplotype analysis was implemented in clinical practice to provide a convenient, economical and effective way for such patients.

In temperate mixed forests, dominant ectomycorrhizal (EM) tree species usually coexist with diverse arbuscular mycorrhizal (AM) understorey tree species. Here, we investigated the spatial associations between AM and EM trees in two > 20 ha temperate forest mega-plots to better understand the observed 'EM-dominant versus AM-diverse' coexistence. Overall, we found that positive spatial associations (e.

Article Synopsis
  • Plant functional traits significantly influence how trees respond to environmental changes, impacting population dynamics like growth, mortality, and recruitment in temperate forests.
  • The study examined 35 species in secondary poplar-birch and Korean pine forests in Northeast China, finding correlations between tree growth and mortality that varied by forest type and successional stage.
  • Results showed that xylem hydraulic and anatomical traits were better predictors of population dynamics in late-successional forests, indicating a stronger relationship between functional traits and tree life processes as the forest matures.

Distinguishing between long-term and short-term effects allows for the identification of different response mechanisms. This study investigated the long- and short-run asymmetric impacts of climate variation on tuberculosis (TB) and constructed forecasting models using the autoregressive distributed lag (ARDL) and nonlinear ARDL (NARDL). TB showed a downward trend, peaking in March-May per year.
