Mechanisms of dual modulatory effects of spermine on the mitochondrial calcium uniporter complex.

The mitochondrial Ca uniporter is the Ca channel responsible for mitochondrial Ca uptake. It plays crucial physiological roles in regulating oxidative phosphorylation, intracellular Ca signaling, and cell death. The uniporter contains the pore-forming MCU subunit, the auxiliary EMRE protein, and the regulatory MICU1 subunit, which blocks the MCU pore under resting cellular Ca concentrations.

Enhancing Activation Energy Predictions under Data Constraints Using Graph Neural Networks.

Accurately predicting activation energies is crucial for understanding chemical reactions and modeling complex reaction systems. However, the high computational cost of quantum chemistry methods often limits the feasibility of large-scale studies, leading to a scarcity of high-quality activation energy data. In this work, we explore and compare three innovative approaches (transfer learning, delta learning, and feature engineering) to enhance the accuracy of activation energy predictions using graph neural networks, specifically focusing on methods that incorporate low-cost, low-level computational data.

Maternal Infections, Antibiotics, Steroid Use, and Diabetes Mellitus Increase Risk of Early-Onset Sepsis in Preterm Neonates: A Nationwide Population-Based Study.

The global evolution of pathogens causing early-onset sepsis (EOS), a critical condition in preterm infants, necessitates a re-evaluation of risk factors to develop updated prevention and treatment strategies. This nationwide case-control study in Taiwan analyzed data from the National Health Insurance Research Database, Birth Reporting Database, and Maternal and Child Health Database from 2010 to 2019. The study included 176,681 mother-child pairs with preterm births.

Investigating the Pulmonary Host Response of Infection-Associated Pneumonia by Metagenomic Next-Generation Sequencing.

For investigating the host response in associated pneumonia, we analyzed the host genetic sequences obtained from metagenomic next-generation sequencing (mNGS). The samples for mNGS were bronchoalveolar lavage fluid (BALF) collected from the lungs of patients infected with and from patients without bacterial infections. BALF samples from patients with pneumonia were collected from the lungs of patients infected with with New Delhi metallo-β-lactamase (NDM, before treatment), A.
