This study investigated the spatiotemporal variation and long-range transport characteristics of atmospheric speciated mercury (ASM) along the West and East Channels surrounding Taiwan Island toward the South China Sea (SCS) in East Asia. Field sampling was conducted at three remote island sites, and potential sources of ASM were examined using backward trajectory clustering and regional fire maps. Seasonally, ASM concentrations followed the order: spring > winter > fall > summer, with higher ASM levels observed in the western waters of Taiwan Island than those in the eastern waters. Among the mercury species, gaseous elemental mercury (GEM) was predominant, and followed by particulate-bound mercury (PBM) and gaseous oxidized mercury (GOM), with total gaseous mercury (TGM = GEM+GOM) accounting for 92.1–98.4 % of ASM. Clustered trajectory analysis indicated that Asian Northeastern Monsoons (ANMs) may transport ASMs originating from continental sources in North and East Asia to the island sites via long-range transport. Slash-and-burn activities in the Indochina Peninsula and mainland China during spring and winter contributed to elevated ASM levels. The West Channel exhibited a pronounced “channel effect,” amplifying industrial emissions across the Taiwan Strait and resulting in higher ASM levels at the Penghu Islands. Conversely, the East Channel received diluted air masses through long-range transport from the Korean Peninsula and North China via Green Island and the Bashi Channel, leading to relatively lower ASM levels at the dongsha Island. Overall, this study highlights the importance of seasonal circulation patterns and regional combustion sources in shaping mercury distribution in the marine boundary layer of East Asia.

Geological structural and rainfall intensity causes the parameters of soil shear strength to decline, especially in the surface layer of soil in volcanic rocks that have not experienced weathering. Study of geological structures and rainfall intensity against the hazard of a landslide was destroyed on the slopes of Mount Abang in the Abang Batudinding Village. Soil investigations using the Geoelectric method and sampling at 6 boreholes. Geological analysis on interpretation of slope outcrops, average rainfall analysis of the Thiessen Polygon method and analysis of design flood discharge using the NHSU method. Analysis results show the morphology of the slopes of Mount Abang with a slope of more than 40% and lithology of weathered volcanic rocks consisting of volcanic breccias, and tuffs breccias in conditions rather mild to moderate weathering, if have average effective rainfall for 10-50 years at 238 mm/day. The results also show that the peak discharge of debris flow was 98.639 m3/sec with the volume of debris flow 50072.85 m3 and the width of the range was 49.5 m. This debris flow volume indicated that residents around the river with a range of 49.5 m are at risk of debris flow sediment with a thickness of 1-1.5 m.

Background: In post-stroke rehabilitation, functional connectivity (FC), motor-related cortical potential (MRCP), and gait activities are common measures related to recovery outcomes. However, the interrelationship between FC, MRCP, gait activities, and bipedal distinguishability have yet to be investigated. Methods: Ten participants were equipped with EEG devices and inertial measurement units (IMUs) while performing lower limb motor preparation (MP) and motor execution (ME) tasks. MRCP, FCs, and bipedal distinguishability were extracted from the EEG signals, while the change in knee degree during the ME phase was calculated from the gait data. FCs were analyzed with pairwise Pearson’s correlation, and the brain-wide FC was fed into support vector machine (SVM) for bipedal classification. Results: Parietal–frontocentral connectivity (PFCC) dysconnection and MRCP desynchronization were related to the MP and ME phases, respectively. Hemiplegic limb movement exhibited higher PFCC strength than nonhemiplegic limb movement. Bipedal classification had a short-lived peak of 75.1% in the pre-movement phase. These results contribute to a better understanding of the neurophysiological functions during motor tasks, with respect to localized MRCP and nonlocalized FC activities. The difference in PFCCs between both limbs could be a marker to understand the motor function of the brain of post-stroke patients. Conclusions: In this study, we discovered that PFCCs are temporally dependent on lower limb gait movement and MRCP. The PFCCs are also related to the lower limb motor performance of post-stroke patients. The detection of motor intentions allows the development of bipedal brain-controlled exoskeletons for lower limb active rehabilitation. © The Author(s) 2024.

A new approach to treating vascular blockages has been developed to overcome the limitations of current thrombolytic therapies. This approach involves biosafety and multimodal plasma-derived theranostic platelet vesicle incorporating iron oxide constructed nano-propellers platformed technology that possesses fluorescent and magnetic features and manifold thrombus targeting modes. The platform is capable of being guided and visualized remotely to specifically target thrombi, and it can be activated using near-infrared phototherapy along with an actuated magnet for magnetotherapy. In a murine model of thrombus lesion, this proposed multimodal approach showed an approximately 80 % reduction in thrombus residues. Moreover, the new strategy not only improves thrombolysis but also boosts the rate of lysis, making it a promising candidate for time-sensitive thrombolytic therapy. © 2023 The Authors

Industrial wastewater pollution harms ecosystems and hinders sustainable development growth. Particularly, hydroquinone (HQ) has transitioned from a commercial chemical to an environmental hazard because of its extensive use in beauty products, pharmaceuticals, chemicals, and food industries. Therefore, developing electrochemical sensors for the detection of HQ is very important for environmental safety. Herein, the 7-ACA monomer was electropolymerized on the glassy carbon electrode (GCE) surface to examine the electrochemical oxidation of HQ utilizing CV (cyclic voltammetry) and dPV (differential pulse voltammetry) techniques. Scanning electron microscopy (SEM) characterization verified the deposition of the p-7-ACA on the glassy carbon electrode (GCE) surface. The designed p-7-ACA@GCE sensor exhibited better electrocatalytic properties. The acquired dPV observations for the p-7-ACA@GCE demonstrated excellent limit of detection (LOd) 8.86 nmol L −1 and broad linear range (0.33 μM to 955 μM) for the detection of HQ. The developed sensor exhibits excellent repeatability, reproducibility, selectivity and better cyclic stability. In addition, the fabricated p-7-ACA@GCE was used to determine the HQ in a different environmental water sample.

Cytokines and chemokines play important roles in inflammation and repair following brain injury. M1 microglia are pro-inflammatory which produce cytokines and lead to neural injury;in contrast, M2 microglia are anti-inflammatory, release neurotrophic factors, and promote neural repair processes. Chemokine CCL5, increased after TBI, shows a neuroprotective function by reducing oxidative stress. CCL5 may contribute to the balance between oxidative stress and immune responses after brain injury. Herein, we investigated the role of CCL5 in microglial polarization after mild traumatic brain injury, focusing on the cerebral cortex.C57BL/6 and CCL5 knockout (CCL5-KO) mice were given a mild traumatic brain injury (TBI) using weight-drop. Neurological parameters such as motor and sensory functions were analyzed by mNSS score, accelerating rotarod, beam walking, and adhesive removal tests. Oxidative stress and neuron damage were measured by NAdph oxidase activity, hypoxyloprobe staining and FJC. Performance of motor and sensory functions in both WT and CCL5-KO mice were impaired after brain injury which recovered after 7 days-post-injury (dpi) in the WT group but only after 14 days in the CCL5-KO mouse group. RT-qPCR analysis revealed that pro-inflammation cytokines - IL-1β, TNF-α, and IL-6 were higher in CCL5-KO mice compared to WT mice at 4 and 14 dpi. In contrast, M2-like microglia markers - IL-10 and Agr-1 were increased in WT mouse cortical tissue at 4 dpi. Oxidative stress increased both M1 and M2- related cytokine expression in BV2 cells treated with H 2 O 2;CCL5 treatment increased M2- but suppressed M1- related cytokine gene activation. Intranasal delivery of CCL5 reduced neuronal oxidative stress, increased IL-10 expression and improved motor and sensory functions in CCL5-KO mice after brain *** summary, CCL5, which alters immune responses and protects neurons from TBI damage, has an important function in regulating M2-like microglial polarization during post-

Tropical cyclones are often accompanied by large amount of precipitation potentially impacting stream hydrochemistry. Global warming is altering typhoon disturbance regime. Little is known about how cyclone changes, especially cyclone-frequency reduction may affect stream hydrochemistry. In this study, we compared water and nutrient input via precipitation and output via streamflow between a frequent-typhoon period (2013–2017), with 1.2 typhoon yr −1 , and a no-typhoon period (2018–2022) at a long-term monitoring site, the Fushan Experimental Forest of Taiwan. Precipitation and streamflow quantities were not different between the two periods because typhoons increased the fluctuation but not the mean of monthly precipitation in the major typhoon months (July–September). Inputs of Mg 2+ , NO 3 − , and SO 4 2− via precipitation were greater in the frequent-typhoon period than the no-typhoon period while inputs of other ions were not different between the two periods. Only the output of Mg 2+ was different between the two periods, greater in the frequent-typhoon period. Output/input ratio of NO 3 − was greater in the no-typhoon period than the frequent-typhoon period despite the greater input in the frequent-typhoon period, while no differences were found for others. Increases in mineralization rates due to warming is suggested to be the cause of the greater NO 3 − output/input ratio during the no-typhoon period. Relationships between stream discharge and ion export were similar between the two periods both with and without removing typhoon events. The limited variation in hydrochemistry between periods of contrasting cyclone activities suggests high resilience of the undisturbed subtropical forests to changes in cyclone frequency at the decadal scale. A no-typhoon period (2018–2022) was observed in Taiwan despite an average of two typhoons per year in 1958–2017 Relationships between stream discharge and ion export were similar between the two periods Output/input rati
