National scale evaluation of nutrient purification capacity in marine sediments along the coast of South Korea: A mesocosm study based in situ assessment.

The ecosystem regulating services from tidal flats, such as removal of organic pollutants, provided by natural tidal flats are being increasingly recognized, yet quantitative evaluation remains limited. Here we evaluated a nationwide capacity of natural purification in tidal flats. Using in situ sediments from five along the Korean coast (Incheon, Gunsan, Sinan, Gwangyang, and Busan), we applied a mesocosm system informed by 18 years of riverine monitoring data from national surveys.

Physiological effects of suspended sediments on marine fish across habitat, development, and behavioral factors.

This study evaluated the physiological responses of four marine fish species (Lateolabrax japonicus, Sebastes schlegelii, Platichthys stellatus, and Paralichthys olivaceus) to suspended sediments (SS) generated by marine sand mining. Using oxygen consumption rate (OCR), osmolality, and mortality as endpoints, the effects of SS concentrations ranging from 0 to 10,000 mg L were assessed. L.

Efficacy of brain-computer interface training with motor imagery-contingent feedback in improving upper limb function and neuroplasticity among persons with chronic stroke: a double-blinded, parallel-group, randomized controlled trial.

Background: Brain-computer interface (BCI) technology can enhance neural plasticity and motor recovery in persons with stroke. However, the effects of BCI training with motor imagery (MI)-contingent feedback versus MI-independent feedback remain unclear. This study aimed to investigate whether the contingent connection between MI-induced brain activity and feedback influences functional and neural plasticity outcomes.

Experiences of Surgical Approach for Aortoduodenal Fistula Repairs in Abdominal Aortic Aneurysm Patients.

Purpose: This study aimed to analyze the characteristics and outcomes of patients with an aortoduodenal fistula (ADF) who underwent surgical treatment at a single institution.

Materials And Methods: The data of patients diagnosed with ADF at the Yonsei University Gangnam Severance Hospital, South Korea, between 2019 and 2022 were included. Primary repair and segmental resection of the duodenum with duodeno-jejunostomy were the two main methods used to repair ADF.

Mitochondrial Transplantation Ameliorates Pulmonary Fibrosis by Suppressing Myofibroblast Activation.

Idiopathic pulmonary fibrosis (IPF) is a pulmonary disease characterized by excessive extracellular matrix protein deposition in the lung interstitium, subsequently causing respiratory failure. IPF still has a high medical unmet requirement due to the lack of effective treatments to inhibit disease progression. The etiology of IPF remains unclear, but mitochondrial dysfunction is considered to be associated with IPF development.
