Respiratory diseases are a leading cause of morbidity in children globally, with significant healthcare costs. The overuse of conventional treatments like antibiotics has raised concerns about antibiotic resistance and side effects. GG (LGG), one of the most extensively studied probiotics, has gained attention as a potential adjunct therapies due to their ability to modulate the gut microbiota and immune responses.

Alveolar morphogenesis initiates at late gestation or postnatal stage during mammalian development and is mediated by coordination among multiple cell types. Here we show that fibroblast-derived Heparan Sulfate Glycosaminoglycan (HS-GAG) is essential for maintaining a niche that supports alveolar formation by modulating both biophysical and biochemical cues.

Background: The Wilms' tumor suppressor gene (WT1) is a critical regulator in kidney development and disease pathogenesis. With the identification of at least 36 isoforms in mammals, each potentially playing distinct roles, WT1's complexity is becoming increasingly apparent. The -KTS and +KTS isoforms, in particular, have been implicated in DNA and RNA regulation, respectively.

However, the similarities and differences in gene expression patterns and immune responses between these two sites have not been extensively studied.
Results: Four lines of matched nasal and bronchial airway epithelial cells obtained from the four patients were embedded in Matrigel and cultured in thechemically defined medium to generate patient-derived nasal organoids (NO) and bronchial organoids (BO).
Introduction: Clinical practice is a cornerstone of undergraduate training in Chinese medical education, ensuring the development of essential skills for future professionals. While flipped classrooms have gained popularity for their potential to enhance learning outcomes, the effectiveness of this approach in clinical settings remains underexplored. This study aims to address this research gap by consolidating evidence on the impact of flipped classrooms through a comprehensive meta-analysis.

The clinical presentation of the adenoviral pneumonia is varied; in severe cases, they may cause systemic multi-system damages. Currently, early clinical differential diagnosis is difficult under the existing testing methods, the study identified potential biomarkers by screening and validating differentially expressed proteins (DEPs), and aimed at distinguishing between severe and non-severe adenovirus pneumonia in children aged <14 years.

Bronchopulmonary dysplasia (BPD) frequently affects extremely preterm and low birth weight infants, with current treatments lacking specificity. Enhancing extra-uterine preterm alveoli development and repairing damage are crucial for BPD management. Here we show that exosomes derived from human umbilical cord mesenchymal stem cells (hucMSCs-Exos) can enhance fetal lung development in mice by delivering specific contents.

Targeting the fungal glycosylphosphatidylinositol acyltransferase GWT1 by manogepix is a promising antifungal strategy. However, the inhibitory mechanism of manogepix remains unclear.

RNA-binding proteins (RBPs) modulate all aspects of RNA metabolism, but a comprehensive picture of RBP expression across tissues is lacking. Here, we describe our development of the method we call HARD-AP that robustly retrieves RBPs and tightly associated RNA regulatory complexes from cultured cells and fresh tissues. We successfully use HARD-AP to establish a comprehensive atlas of RBPs across mouse primary organs.

Methods: In a phase 3, multicenter, double-blind, randomized, placebo-controlled trial conducted in China, we enrolled participants 1 to 24 months of age who were hospitalized with RSV infection.
Bronchopulmonary dysplasia (BPD) is a chronic lung disease of preterm infants, with its incidence rising due to improved survival rates of these infants. BPD results from a combination of prenatal and postnatal factors, such as mechanical ventilation, oxygen toxicity, and infections, all of which significantly impact the prognosis and growth of affected infants. Current treatment options for BPD are largely supportive and do not address the underlying pathology.

The maternal drug exposure birth cohort (DEBC) study, a prospective longitudinal investigation, aims to explore the correlation of maternal drug exposure during pregnancy with pregnancy outcomes, and establish a human biospecimen biobank. Here we describe the process of establishing DEBC and show that the drug exposure rate in the first trimester of pregnant women in DEBC (n = 112,986) is 30.
