Purpose: The aim of this study was to evaluate the efficacy of mesenchymal stem cells (MSCs) in a nitrofen-induced congenital diaphragmatic hernia (CDH) rat model.
Methods: Pregnant rats were exposed to nitrofen on embryonic day 9.5 (E9.5). MSCs were isolated from the enhanced green fluorescent protein (eGFP) transgenic rat lungs. The MSCs were transplanted into the nitrofen-induced E12.5 rats via the uterine vein, and the E21 lung explants were harvested. The study animals were divided into three: the control group, the nitrofen-induced left CDH (CDH group), and the MSC-treated nitrofen-induced left CDH (MSC-treated CDH group). The specimens were morphologically analyzed using HE and immunohistochemical staining with proliferating cell nuclear antigen (PCNA), surfactant protein-C (SP-C), and α-smooth muscle actin.
Results: The alveolar and medial walls of the pulmonary arteries were significantly thinner in the MSC-treated CDH group than in the CDH group. The alveolar air space areas were larger, while PCNA and the SP-C positive cells were significantly higher in the MSC-treated CDH group, than in the CDH group. MSC engraftment was identified on immunohistochemical staining of the GFP in the MSC-treated CDH group.
Conclusions: MSC transplantation potentially promotes alveolar and pulmonary artery development, thereby reducing the severity of pulmonary hypoplasia.

Lytic polysaccharide monooxygenases (LPMOs) are a unique group of monocopper enzymes that exhibit remarkable ability to catalyze the oxidative cleavage of recalcitrant carbohydrate substrates, such as cellulose and chitin, by utilizing O or HO as the oxygen source. One of the key challenges in understanding the catalytic mechanism of LPMOs lies in deciphering how they activate dioxygen using diverse reductants. To shed light on this intricate process, we conducted in-depth investigations using quantum mechanical/molecular mechanical (QM/MM) metadynamics simulations, molecular dynamics (MD) simulations, and density functional theory (DFT) calculations.

Background: The landscape of co-occurring birth defects among infants with congenital diaphragmatic hernia (CDH) remains underexplored.
Aims: This study aims to elucidate the complex patterns of co-occurring defects in Chinese population.
Materials And Methods: We analyzed cases from the Chinese Birth Defects Monitoring Network (2007-2019) with CDH that presented along with at least one additional defect but without a syndromic diagnosis.
Early Removal of the Abdominal Patch is Superior to Late Removal in Children With Congenital Diaphragmatic Hernia.

Introduction: Open repair of Congenital diaphragmatic hernia (CDH) in neonates often involves reconstruction of the abdominal wall using a patch. Data on predictors for the need of a patch and associated postoperative risks, such as infection or patch detachment, are limited. Specifically, the question regarding the ideal timepoint of patch removal remains unanswered.

Background/aim: Congenital diaphragmatic hernia (CDH) is a critical condition affecting newborns, which often results in long-term morbidities, including neurodevelopmental delays, which affect cognitive, motor, and behavioral functions. These delays are believed to stem from prenatal and postnatal factors, such as impaired lung development and chronic hypoxia, which disrupt normal brain growth. Understanding the underlying mechanisms of these neurodevelopmental impairments is crucial for improving prognosis and patient outcomes, particularly as advances in treatments like ECMO have increased survival rates but also pose additional risks for neurodevelopment.

Introduction: Timing of repair for infants with congenital diaphragmatic hernia (CDH) requiring extracorporeal life support (ECLS) remains controversial. Approaches include early repair on ECLS, late repair on ECLS, or repair after ECLS decannulation; all have potential risks and benefits. To mitigate risk and maximize benefit, our group developed an individualized hybrid model in 2016 in which approach is based on prenatal risk stratification.
