Abstract	A key aspect of "One Health" is to comprehend how antibiotic resistomes evolve naturally. In this issue, Nguyen and colleagues pioneered an in situ investigation on the impact of protist predations on the soil microbial community and its antibiotic resistance genes (ARGs). They found that bacterivorous protists consistently increased the abundance of ARGs, such as tetracycline resistant genes. Indeed, antibiotic production is a common strategy for bacteria to evade protist predation. The rise of ARGs can be explained by the balance between antibiotic producers and resisters shaped by predatory selection. This work suggests that ARG enrichment due to biotic interactions may be less worrisome than previously thought. Unless, these ARGs are carried by or disseminated among pathogens. Therefore, it is essential to monitor the occurrence, dissemination and pathogenic hosts of ARGs, enhancing our capacity to combat antibiotic resistance.

Abstract	Nucleoside phosphorylases (NPs) are the key enzymes in the nucleoside metabolism pathway and are widely employed for the synthesis of nucleoside analogs, which are difficult to access via conventional synthetic methods. NPs are generally classified as purine nucleoside phosphorylase (PNP) and pyrimidine or uridine nucleoside phosphorylase (PyNP/UP), based on their substrate preference. Here, based on the evolutionary information on the NP-I family, we adopted an insertions-deletions (InDels) strategy to engineer the substrate promiscuity of nucleoside phosphorylase

Abstract	Overyielding, the high productivity of multispecies plant communities, is commonly seen as the result of plant genetic diversity. Here we demonstrate that biodiversity-ecosystem functioning relationships can emerge in clonal plant populations through interaction with microorganisms. Using a model clonal plant species, we found that exposure to volatiles of certain microorganisms led to divergent plant phenotypes. Assembling communities out of plants associated with different microorganisms led to transgressive overyielding in both biomass and seed yield. Our results highlight the importance of belowground microbial diversity in plant biodiversity research and open new avenues for precision ecosystem management.

Abstract	Fabricated pea protein isolate (PPI) nanofibrils were used as nanocarriers to encapsulate, stabilize and deliver resveratrol (RES). PPI nanofibrils possessed a dramatically higher surface hydrophobicity than PPI (native), and PPI nanofibrils exhibited nanoscale widths of 10 nm and average lengths of 1.0 μm. Fluorescence analyses demonstrated PPI nanofibrils had high binding constant with RES. Compared with RES (free), the aqueous solubility of RES was improved by approximately 1000-fold with PPI nanofibrils complex. DPPH and ABTS radical scavenging activity assays showed that the antioxidant capacity of RES was pronouncedly enhanced through the nanocomplexation with PPI nanofibrils. RES-PPI nanofibrils complexes exhibited higher antiproliferative activities than RES (free), with the cell viabilities of 52.6% and 38.5% for RES (free) and RES-PPI nanofibrils complex at 20 μg/mL. This study demonstrates that PPI nanofibrils can be utilized as novel nanocarriers for improvements of the water solubility, chemical stability and in vitro biological activities of hydrophobic nutraceuticals.

Abstract	Objective: Hemorrhagic stroke is a leading threat to human's health. The fast-developing microwave-induced thermoacoustic tomography (MITAT) technique holds potential to do brain imaging. However, transcranial brain imaging based on MITAT is still challenging due to the involved huge heterogeneity in speed of sound and acoustic attenuation of human skull. This work aims to address the adverse effect of the acoustic heterogeneity using a deep-learning-based MITAT (DL-MITAT) approach for transcranial brain hemorrhage detection. Methods: We establish a new network structure, a residual attention U-Net (ResAttU-Net), for the proposed DL-MITAT technique, which exhibits improved performance as compared to some traditionally used networks. We use simulation method to build training sets and take images obtained by traditional imaging algorithms as the input of the network. Results: We present ex-vivo transcranial brain hemorrhage detection as a proof-of-concept validation. By using an 8.1-mm thick bovine skull and porcine brain tissues to perform ex-vivo experiments, we demonstrate that the trained ResAttU-Net is capable of efficiently eliminating image artifacts and accurately restoring the hemorrhage spot. It is proved that the DL-MITAT method can reliably suppress false positive rate and detect a hemorrhage spot as small as 3 mm. We also study effects of several factors of the DL-MITAT technique to further reveal its robustness and limitations. Conclusion: The proposed ResAttU-Net-based DL-MITAT method is promising for mitigating the acoustic inhomogeneity issue and performing transcranial brain hemorrhage detection. Significance: This work provides a novel ResAttU-Net-based DL-MITAT paradigm and paves a compelling route for transcranial brain hemorrhage detection as well as other transcranial brain imaging applications.

Abstract	Background: The development of transoral endoscopic vestibular approach thyroidectomy (TOETVA) has been limited by inherent defects, such as mental nerve injury and carbon dioxide (CO Methods: We reviewed 75 patients who successfully underwent gasless STET using novel instruments at our institution from November 2020 to November 2021. A main incision of approximately 2 cm was made in the natural submental crease line and then combined with two vestibule incisions to complete the procedure. Demographic data, surgical technique and perioperative outcomes were retrospectively recorded. Results: Thirteen male and sixty-two female patients with a mean age of 34.0 ± 8.1 years were enrolled in this study. Sixty-eight patients had papillary thyroid carcinomas and seven had benign nodules. We successfully performed all gasless STET without conversion to open surgery. The average postoperative hospital stay was 4.2 ± 1.8 days. One transient recurrent laryngeal nerve injury and two transient hypoparathyroidisms were observed. Three patients complained of slight lower lip numbness on the first postoperative day. One case of lymphatic fistula, subcutaneous effusion, and incision swelling occurred each, all of which were conservatively cured. One patient developed a recurrence six months after surgery. Conclusions: Gasless STET using our own designed suspension system is technically safe and feasible with reasonable operative and oncologic results.

Abstract	Ralstonia solanacearum PhcB and PhcA control a quorum-sensing (QS) system that globally regulates expression of about one third of all genes, including pathogenesis genes. The PhcB-PhcA QS system positively regulates the production of exopolysaccharide (EPS) and negatively regulates hrp gene expression, which is crucial for the type III secretion system (T3SS). Both EPS and the T3SS are essential for pathogenicity. The gene rsc2734 is located upstream of a phcBSR operon and annotated as a response regulator of a two-component system. Here, we demonstrated that RSc2734, hereafter named PrhX, positively regulated hrp gene expression via a PrhA-PrhIR-PrhJ-HrpG signalling cascade. Moreover, PrhX was crucial for R. solanacearum to invade host roots and grow in planta naturally. prhX expression was independent of the PhcB-PhcA QS system. PrhX did not affect the expression of phcB and phcA and the QS-dependent phenotypes, such as EPS production and biofilm formation. Our results provide novel insights into the complex regulatory network of the T3SS and pathogenesis in R. solanacearum.

Abstract	Background: The transoral endoscopic thyroidectomy vestibular approach (TOETVA) is receiving increased attention, frequently due to growing requirements for cosmetic incisions. Here, we report our initial experience and discuss the safety and efficacy of the innovative surgical working space suspension system for gasless TOETVA. Methods: We retrospectively analyzed 75 consecutive patients for whom gasless TOETVA with our novel working space suspension system was used. This suspension system included self-developed retractors, a sterile bandage, and an anesthesia stand. We also improved some main surgical instruments in gasless TOETVA. Results: The study included 75 patients who successfully underwent thyroidectomy and central neck dissection via gasless TOETVA. The mean operating time was 143.27 ± 34.60 min. The mean number of retrieved lymph nodes was 8.00 ± 5.39. Conversion to open surgery did not occur, nor did patients exhibit serious postoperative complications. Postoperative complications included 4 cases of transient recurrent laryngeal nerve (RLN) palsy, 9 of transient hypoparathyroidism, and 3 of transient mental nerve injury. One patient with subcutaneous fluid after surgery recovered after aspiration. Another patient with submental minor perforation recovered well after suturing. There was no evidence of specific complications related to self-designed retractors. Conclusion: The innovative working space suspension system for gasless TOETVA provided enough and stable working space and optimized the clarity of the surgical field without CO
