Corticomuscular Coherence Existed at the Single Motor Unit Level.

The monosynaptic cortico-motoneuronal connections suggest the possibility of individual motor units (MUs) receiving independent commands from motor cortex. However, previous studies that used corticomuscular coherence (CMC) between electroencephalogram (EEG) signals and electromyogram (EMG) signals have not directly explored the corticospinal functionality at the single motoneuron level. The objective of this study is to find out whether synchronous activities exist between the motor cortex and individual MUs.

Optimizing Triage in Chemical Disasters: Validation of Modified IGSA Criteria for Hydrofluoric Acid Exposure.

Objective: This study aimed to develop and validate the modified irritant gas syndrome agent (IGSA) criteria, utilizing readily available triage information and epidemiologic data to efficiently segregate patients based on the severity of hydrofluoric acid (HFA) exposure.

Methods: A retrospective analysis of 160 patients exposed to HFA was performed to develop the criteria and assess the criteria's efficacy, focusing on age, respiratory rate, and compliance with IGSA standards. The criteria's validity was assessed by comparing clinical outcomes between patients meeting the modified IGSA (mIGSA) criteria and those who did not as external and internal.

Natural and anthropogenic factors controlling organic carbon storage in riverine wetlands along South Korea's four rivers.

This study explores carbon sequestration in South Korea's riverine wetlands, focusing on the four major rivers: Han, Yeongsan, Geum, and Nakdong. Field data from the Yeongsan River wetland, including 3D topography surveys, grainsize analyses, and loss-on-ignition measurements, were used to assess carbon stocks and their environmental drivers. The Yeongsan River was selected as a representative site due to its geomorphological, hydrological, and climatic similarities with the other three major rivers, which influence sediment transport and carbon dynamics.

The purpose of this study was to evaluate whether the optimal operating points of adult-oriented artificial intelligence (AI) software differ for pediatric chest radiographs and to assess its diagnostic performance. Chest radiographs from patients under 19 years old, collected between March and November 2021, were divided into test and exploring sets. A commercial adult-oriented AI software was utilized to detect lung lesions, including pneumothorax, consolidation, nodule, and pleural effusion, using a standard operating point of 15%.

Enhancing toxicity prediction for natural products in herbal medicine and dietary supplements: Integrating (Q)STR models and in vitro assays.

New approach methods (NAMs) are required to predict human toxicity effectively, particularly due to limitations in conducting in vivo studies. While NAMs have been established for various industries, such as cosmetics, pesticides, and drugs, their applications in natural products (NPs) are lacking. NPs' complexity (multiple ingredients and structural differences from synthetic compounds) complicates NAM development.

Discontinuation rates, clinical effects and provocation factors of SGLT-2 inhibitor in the real world.

Sodium-glucose cotransporter 2 (SGLT-2) inhibitors are the only medications that improve clinical outcomes regardless of baseline left ventricular ejection fraction. Despite the recognized effectiveness of SGLT-2 inhibitors, there remains a paucity of research on the discontinuation of these medications. The objective of this study is to analyze the rate of discontinuation of SGLT-2 inhibitors, to evaluate the impact of discontinuation on the clinical outcome, and to identify the factors associated with discontinuation.

Investigations on the Origin of Topotactic Phase Transition of LaCoO Thin Films with In Situ XRD and Ambient Pressure Hard X-ray Photoelectron Spectroscopy.

With the applications of in situ X-ray diffraction (XRD), electrical - measurement, and ambient pressure hard X-ray photoelectron spectroscopy (AP-HAXPES), the characteristics of the topotactic phase transition of LaCoO (LCO) thin films are examined. XRD measurements show clear evidence of structural phase transition (SPT) of the LCO thin films from the perovskite (PV) LaCoO to the brownmillerite (BM) LaCoO phases through the intermediate LaCoO phase at a temperature of 350 °C under high-vacuum conditions, ∼10 mbar. The reverse SPT from BM to PV phases is also found under ambient pressure (>100 mbar) of air near 100 °C.

Development of a multi-scale nanofiber scaffold platform for structurally and functionally replicated artificial perforating arteries.

Experimental models for exploring abnormal brain blood vessels, including ischemic stroke, are crucial in neuroscience; recently, significant attention has been paid to artificial tissues through tissue engineering. Nanofibers, although commonly used as tissue engineering scaffolds, undergo structural deformations easily, making it challenging to create uniform tissue, especially for the smallest-diameter ones such as perforating arteries. This study focused on the development of a platform capable of reconstructing structurally and functionally replicated perforating arteries.
