    Abstract Brachial plexus avulsion (BPA), which commonly occurs in neonatal birth injuries and car accidents, severely disrupts spinal cord segments and nerve roots. Avulsion is usually located in the transitional zone at the junction of spinal nerve roots and starting point of the spinal cord, which places heavy disability burdens on patients due to sensory and motor function loss in the innervated areas. Primary mechanical injuries and secondary pathogenesis, such as inflammatory infiltration and oxidative stress, lead to inefficient management and poor prognosis. Astaxanthin (AST) has a strong ability to bleach singlet oxygen and capture free radicals, quench singlet oxygen and trap free radicals, and folic acid (FC) can effectively inhibit the inflammatory response. This study aimed to investigate the therapeutic effects of AST and FC on BPA. The 24 h after BPA was considered the acute phase of the injury, and the combination of AST and FC had the best therapeutic effect due to the synergistic effect of AST's antioxidant and FC's anti-inflammatory properties. At 6 weeks after BPA, AST-FC promoted the recovery of biceps motor functions, increased myofiber diameter, enlarged the amplitude of musculocutaneous nerve-biceps compound action potential, and improved Terzis grooming test (TGT) scores. Meanwhile, more functional ventral horn motor neurons in the spinal cord were maintained. In conclusion, AST-FC combined therapy has a potential role in the clinical management of BPA since it can effectively alleviate oxidative stress and the inflammatory response in the acute phase of BPA, increase the survival rate of neurons, and promote neuronal regeneration and recovery of motor functions in the late stage of BPA.

    Abstract Traffic flow forecasting is challenging due to the intricate spatio-temporal correlations in traffic flow data. Existing Transformer-based methods usually treat traffic flow forecasting as multivariate time series (MTS) forecasting. However, too many sensors can cause a vector with a dimension greater than 800, which is difficult to process without information loss. In addition, these methods design complex mechanisms to capture spatial dependencies in MTS, resulting in slow forecasting speed. To solve the abovementioned problems, we propose a Fast Pure Transformer Network (FPTN) in this paper. First, the traffic flow data are divided into sequences along the sensor dimension instead of the time dimension. Then, to adequately represent complex spatio-temporal correlations, Three types of embeddings are proposed for projecting these vectors into a suitable vector space. After that, to capture the complex spatio-temporal correlations simultaneously in these vectors, we utilize Transformer encoder and stack it with several layers. Extensive experiments are conducted with 4 real-world datasets and 13 baselines, which demonstrate that FPTN outperforms the state-of-the-art on two metrics. Meanwhile, the computational time of FPTN spent is less than a quarter of other state-of-the-art Transformer-based models spent, and the requirements for computing resources are significantly reduced.

    Abstract Dissolved black carbon (DBC) is an important constituent of the natural organic carbon pool, influencing the global carbon cycling and the fate processes of many pollutants. In this work, we discovered that DBC released from biochar has intrinsic peroxidase-like activity. DBC samples were derived from four biomass stocks, including corn, peanut, rice, and sorghum straws. All DBC samples catalyze H₂O₂ decomposition into hydroxyl radicals, as determined by the electron paramagnetic resonance and the molecular probe. Similar to enzymes that exhibit saturation kinetics, the steady-state reaction rates follow the Michaelis−Menten equation. The peroxidase-like activity of DBC is controlled by the ping-pong mechanism, as suggested by parallel Lineweaver−Burk plots. Its activity increases with temperature from 10 to 80 °C and has an optimum at pH 5. The peroxidase-like activity of DBC is positively correlated with its aromaticity as aromatics can stabilize the reactive intermediates. The active sites in DBC also involve oxygen-containing groups, as inferred by increased activity after the chemical reduction of carbonyls. The peroxidase-like activity of DBC has significant implications for biogeochemical processing of carbon and potential health and ecological impacts of black carbon. It also highlights the need to advance the understanding of the occurrence and role of organic catalysts in natural systems.

    Abstract Lily (Lilium spp.) is one of the main ornamental plants grown in the world. In addition, bulbs of lily have been extensively used as edible and medicinal herbs in northern and eastern Asia, especially in China (Yu et al. 2015; China Pharmacopoeia Committee 2020; Tang et al. 2021). In August of 2021, a disease of stem and leaf rot was observed on lily cultivar 'White planet' with approximately 25% disease incidence in the greenhouse and fields at the Institute of Vegetables and Flowers, Chinese Academy of Agricultural Sciences (Beijing, China). The bulbs of symptomatic plants were brown and rotten, with sunken lesions. Symptomatic plants showed short, discolored leaves, and eventually lead to stem wilt and death of the whole plants. Infected bulbs were surface sterilized in 75% ethanol for 30 s, then in 2% sodium hypochlorite for 5 min, and rinsed three times with sterile distilled water. A 0.5×0.5 cm2 tissue piece was then placed on potato dextrose agar (PDA) medium and incubated at 25±1℃. After 5 days, the isolate was purified by single spore isolation technique. The singled-spored fungal colony was characterized by fluffy white aerial mycelia, and produced orange pigments with age. After seven days on Spezieller Nahrstoffarmer agar (SNA), conidia produced from simple lateral phialides. Macroconidia have pronounced dorsiventral curvature typical, significantly enlarged in the middle, a tapered whip-liked pointed apical cell and characteristic foot-shaped basal cell, 3 to 6 septate, measuring 18.71 to 43.01×2.89 to 5.56 μm with an average size of 26.98×3.90 μm (n=30). Microconidia were not observed. Typical verrucose thick chlamydospore with rough walls were profuse in chains or clumps, ellipsoidal to subglobose. These morphological characteristics were consistent with Fusarium spp. (Leslie et al. 2006). For molecular identification, the internal transcribed spacer (ITS), translation elongation factor subunit 1-alpha (TEF1-α) and RNA polymeraseⅡsubunit 2 (RPB2) genes were amplified using primers ITS1/ITS4, EF1/EF2 and 5F2/7cR respectively and sequenced (White et al. 1990; Jiang et al. 2018; O'Donnell et al. 2007). Sequences were submitted to GenBank under accession numbers OM078499 (ITS), Accession OM638086 (TEF1-α) and OM638085 (RPB2). BLAST analysis showed that ITS, TEF1-α and RPB2 sequences shared 100%, 99.8%, 99.2% identity to F. equiseti (OM956073, KY081599, MW364892) in GenBank, respectively. In addition, ITS, TEF1-α and RPB2 sequences shared 100%, 99.53%, 100% identity with Fusarium lacertarum (LC7927, Fusarium incarnatum-equiseti species complex) in the Fusarium-ID database. Based on the morphological characteristics and molecular sequences, the isolates were identified as Fusarium equiseti. A pathogenicity test was performed on potted lily ('White planet') under greenhouse conditions (25±1℃ with a 16 h light and 8 h dark cycle). Three healthy lily bulbs were selected and one bulb was planted in each pot filled with sterilized soil. Each pot was inoculated with 5 mL of conidia suspension (1×107 conidia/mL) in te soil around bulbs with a stem length of 3 cm, with an equal amount of sterilized water as a control. This test had three replicates. After 15 days of inoculation, typical symptoms of bulb rotten, like those observed in the greenhouse and fields, developed on the inoculated plants but not on the controls. The same fungus was consistently reisolated from the diseased plants. To our knowledge, this is the first report that F. equiseti caused bulb rot on Lilium in China. Our result should help with future monitoring and control of lily wilt disease.
