Abstract
The purpose of this study was to investigate the volatile flavor changes in silver carp mince (SCM) gel glycated with different reducing sugars (glucose, L-arabinose, and xylose) based on E-nose, GC-IMS, and sensory evaluation. These results showed that glycation reduced the fishy smell of SCM gel and increased the meaty, toasty, and burnt smell. A total of 10 volatile compounds were considered as characteristic flavor compounds and potential markers. Among them, the main contributors of fishy included hexanal, heptanal, n-nonanal, octanal, etc. Toasty and burnt were mainly related to the production of 3-methylbutanal and furfurol. These results heralded that glycation could be used to improve the volatile flavor of SCM. This research provided a theoretical basis and technical support for glycation in aquatic food flavor quality control, aquatic pre-made food development, and aquatic leisure food processing.

Abstract
OBJECTIVES We aimed to explore the level of protective behaviors against COVID-19 and its association with psychological factors in China and South Korea during the Omicron wave. STUDY DESIGN Cross-sectional study. METHODS We conducted a population-based cross-sectional survey from March 15 to 30, 2023 in China and South Korea. Demographic characteristics, health status, protective behaviors, and psychological factors (including perceived risks, efficacy belief, attribution of disease, fear of COVID-19, trust and evaluation, fatalism, resilience, and pandemic fatigue) were investigated. After adjusting for sociodemographic and health-related factors, multivariable regression models were constructed to explore the psychological influencing factors of protective behavior. RESULTS A total of 3000 participants from China and 1000 participants from Korea were included in the final analysis. The mean performance score for protective behaviors among all respondents was 2.885 in China and 3.139 in Korea, with scores ranging from 1 to 4. In China, performance scores were higher in those who were female, aged 30-39, employed, married, living in urban areas, having the highest income level, having the best subjective health status, and having a history of chronic disease (P-value <0.05). In Korea, performance scores were higher for individuals who were female, over 50 years old, educated to high school or below, unemployed, married, had a history of chronic disease, and had never been infected with SARS-CoV-2 (P-value <0.05). In the multivariable regression model, perceived severity (β = 0.067), attribution of disease (β = 0.121), fear of COVID-19 (β = 0.128), trust and evaluation (β = 0.097), psychological resilience (β = 0.068), and efficacy belief (β = 0.216) were positively associated with the performance scores, pandemic fatigue (β = -0.089) was negatively associated with performance scores in China (P-value <0.05). However, in Korea, perceived susceptibility (β = 0.075), fear of COVID-19 (β = 0.107), and efficacy belief (β = 0.357) were positively associated with protective behaviors (P-value <0.05), trust and evaluation (β = -0.078) and pandemic fatigue (β = -0.063) were negatively associated with performance scores (P-value <0.05). CONCLUSIONS Populations in both China and Korea demonstrated great compliance with protective behaviors during the Omicron wave. Because of the sociocultural, economic, and political differences, there were differences in the association between psychological factors and protective behaviors in the two countries. This study, from the perspective of psychological factors in different cultural contexts, would provide references for increasing adherence to protective guidelines in future outbreaks of emerging infectious diseases.

Abstract
Breathing techniques, particularly slow-paced breathing (SPB), have gained popularity among athletes due to their potential to enhance performance by increasing cardiac vagal activity (CVA), which in turn can help manage stress and regulate emotions. However, it is still unclear whether the frequency of SPB affects its effectiveness in increasing CVA. Therefore, this study aimed to investigate the effects of a brief SPB intervention (i.e., 5 min) on CVA using heart rate variability (HRV) measurement as an index. A total of 75 athletes (22 female; Mage = 22.32; age range = 19-31) participated in the study, attending one lab session where they performed six breathing exercises, including SPB at different frequencies (5 cycles per minute (cpm), 5.5 cpm, 6 cpm, 6.5 cpm, 7 cpm), and a control condition of spontaneous breathing. The study found that CVA was significantly higher in all SPB conditions compared to the control condition, as indexed by both root mean square of the successive differences (RMSSD) and low-frequency HRV (LF-HRVms2). Interestingly, LF-HRVms2 was more sensitive in differentiating the respiratory frequencies than RMSSD. These results suggest that SPB at a range of 5 cpm to 7 cpm can be an effective method to increase CVA and potentially improve stress management and emotion regulation in athletes. This short SPB exercise can be a simple yet useful tool for athletes to use during competitive scenarios and short breaks in competitions. Overall, these findings highlight the potential benefits of incorporating SPB into athletes' training and competition routines.

Abstract
Hemerocallis citrina Borani is a commonly consumed food in Asia and possesses many biologically active ingredients. In this study, a protein named Hemerocallis citrina Borani protein (HcBP) was purified using ammonium sulfate fractionation and anion exchange chromatography. Protease assays revealed that HcBP has peroxidase activity. Meanwhile, the UV absorption spectrum showed that HcBP contains heme. Notably, HcBP showed significant inhibitory effects on human hepatoma cancer cell proliferation. Mechanism investigations indicated that HcBP treatment resulted in overproduction of reactive oxygen species (ROS) and induced mitochondria-dependent apoptosis in human hepatoma cancer cells. Furthermore, we found HcBP not only downregulated pyruvate kinase M2 (PKM2) activity but also decreased the expression and nuclear levels of PKM2. The inhibition of PKM2 led to the downregulation of GLUT1, LDHA and PDK, and thus caused the suppression of glycolysis. In summary, our results suggested that HcBP has potential anti-hepatocellular carcinoma activity.

Abstract
Introduction: The effective and persistent suppression of hepatitis B surface antigen (HBsAg) in patients with chronic HBV infection (CHB) is considered to be a promising approach to achieve a functional cure of hepatitis B. In our previous study, we found that the antibody E6F6 can clear HBsAg through FcγR-mediated phagocytosis, and its humanized form (huE6F6 antibody) is expected to be a new tool for the treatment of CHB. Previous studies have shown that the glycosylation of Fc segments affects the binding of antibodies to FcγR and thus affects the biological activity of antibodies in vivo. Methods: To further improve the therapeutic potential of huE6F6, in this study, we defucosylated huE6F6 (huE6F6-fuc-), preliminarily explored the developability of this molecule, and studied the therapeutic potential of this molecule and its underlying mechanism in vitro and in vivo models. Results: huE6F6-fuc- has desirable physicochemical properties. Compared with huE6F6-wt, huE6F6-fuc- administration resulted in a stronger viral clearance in vivo. Meanwhile, huE6F6-fuc- keep a similar neutralization activity and binding activity to huE6F6-wt in vitro. Immunological analyses suggested that huE6F6-fuc- exhibited enhanced binding to hCD32b and hCD16b, which mainly contributed to its enhanced therapeutic activity in vivo. Conclusions: In summary, the huE6F6-fuc- molecule that was developed in this study, which has desirable developability, can clear HBsAg more efficiently in vivo, providing a promising treatment for CHB patients. Our study provides new guidance for antibody engineering in other disease fields.

Abstract
Paclitaxel-induced peripheral neuropathy (PIPN) is a neurological disorder resulting from paclitaxel (PTX) treatment for cancer patients. There are currently no drugs available that can definitively prevent or treat PIPN. Exosomes are cell-secreted nanoscale vesicles that mediate communication between neurons and glial cells. We found that Schwann cell-derived exosomes (SC-EXOs) robustly improved PIPN both in vitro and in vivo. In vivo studies showed that SC-EXOs were able to alleviate PTX-induced mechanical nociceptive sensitization in rats. Pathomorphological analysis showed that SC-EXOs ameliorated PTX-induced plantar intraepidermal nerve fiber loss and dorsal root ganglion (DRG) injury. Additionally, the results of in vitro studies showed that SC-EXOs had significant protective effects on the DRG cells damaged by PTX, and did not affect the antitumor effect of PTX against Hela cells. Further, mechanism research revealed that SC-EXOs promoted axonal regeneration and protected damaged neurons by upregulating miR-21 to repress the phosphatase and tensin homolog (PTEN) pathway, which could improve PIPN. Taken together, these findings suggest that SC-EXOs ameliorate PTX-induced peripheral neuropathy via the miR-21-mediated PTEN signaling pathway, which provides a novel strategy for the treatment of PIPN.

Abstract
The interfacial void and delamination between the hydrogel electrolyte and flexible electrode caused by the inconformal contact and weak adhesion lead to serious performance degradation of solid-state-sandwiched supercapacitors (SCs) upon repetitive deformation. Herein, we propose a hydrogel polymer electrolyte (HPE) engineering strategy for enhancing the interfacial adhesion (Γ) to achieve extremely durable SCs via the soft, tough, and self-adhesive HPE. Using a self-cross-linked poly(N-hydroxyethyl acrylamide)/H3PO4 (PHEAA/H3PO4) HPE as the model, the interfacial adhesion between HPE and polyaniline (PANI)-modified carbon cloth (CC) electrode (CC/PANI) reaches up to 556 J/m2, leading to excellent durability of electrochemical performance under long-term repetitive deformations. The as-assembled sandwiched SC retains 94.14 and 93.62% of initial capacitance after 180° bending and twisting for 100,000 cycles, respectively. Furthermore, benefiting from the addition of H3PO4, the flexible sandwiched SC displays excellent tolerance to low temperatures and delivers a capacitance retention of 98.03% after 180° bending for 10,000 cycles at -20 °C. This work highlights the importance of interfacial adhesion engineering for the design of extremely deformation-tolerable SCs.

Abstract
Paclitaxel-induced peripheral neuropathy (PIPN) is one of the common adverse effects during the paclitaxel (PTX) treatment of cancer. In this study, we investigated the neuroprotective effects and mechanisms of thymoquinone (TQ) in the PIPN model. Through pain behavioral assays and histological assessment, we demonstrated that TQ significantly alleviated the nociceptive behavior, modulated the pathological changes in peripheral nerves, and decreased the expression of inflammatory factors TNF-α, IL-1β, and IL-6 induced by PIPN in mice. In addition, TQ significantly reversed the reduced viability and inflammatory response of primary DRG neurons caused by PTX. Moreover, the gene expression of related pathways was detected by Western blot, qPCR, and immunofluorescence, and the results showed that TQ exerts neuroprotective effects by regulating TLR4/MyD88 and its downstream NF-κB and MAPKs inflammatory pathways in vivo and in vitro. The treatment with TLR4 antagonist TAK-242 further indicated the important role of the TLR4/MyD88 signaling pathway in PIPN. Furthermore, molecular docking and a cellular thermal shift assay were used to confirm the interaction of TQ with TLR4. In summary, our study shows that TQ can inhibit inflammatory responses against PIPN by regulating TLR4 and MyD88 and its downstream inflammatory pathways.

Abstract
Indole derivatives have garnered considerable attention in the realm of biochemistry due to their multifaceted properties. In this study, we undertake a systematic investigation of the vibrational characteristics of a model indole derivative, 6-isocyano-1-methyl-1H-indole (6ICMI), by employing a combination of FTIR, IR pump-probe spectroscopy, and theoretical calculations. Our findings demonstrate a strong dependence of the isonitrile stretching frequency of 6ICMI on the polarizability of protic solvents and the density of hydrogen-bond donor groups in the solvent when the isonitrile group is bonded to aromatic groups. Both experimental and theoretical analyses unveil a significant correlation between the isonitrile stretch vibration of 6ICMI and the solvent acceptor number of alcohols. Furthermore, the polarization-controlled infrared pump-probe conducted on 6ICMI in dimethyl sulfoxide provides additional support for the potential use of the isonitrile stretching mode of 6ICMI as an effective infrared probe for local environments.

Abstract
Postoperative intrauterine adhesion (IUA), caused by endometrial basal layer injury, is one of the main causes of female infertility. The excessive deposition of fibrin as well as fibroblast is considered the root cause of IUA. However, few clinical strategies are effective in preventing extracellular matrix (ECM) deposition at endometrial wounds that include protein and cell deposits. Herein, the injectable granular poly(N-(2-hydroxyethyl) acrylamide) (PHEAA) hydrogel (granular PHEAA gel), which presents excellent antifouling properties and remarkably prevents protein and cell adhesions, is used to prevent postoperative IUA. The granular PHEAA gel with a jammed network structure exhibits outstanding injectability and superior stability. Compared with the IUA group, the granular PHEAA gel can promote regeneration of the endometrium while reducing the area of endometrial fibrosis. Immunohistochemical staining experiments indicate that the granular PHEAA gel can improve the proliferation of the endometrium, promote vascularization, and enhance anti-inflammatory effect in IUA rats. And the granular PHEAA gel can effectively slow down the fibrosis of uterine tissue. Importantly, the number of embryos is significantly increased after injecting granular PHEAA gel, inferring that there is an obvious reproductive function recovery of injured endometrium.

Abstract
Oro-maxillofacial cone-beam CT (CBCT) is the most widely used three-dimensional imaging method in the field of oral and maxillofacial radiology. It has been widely used in China, while radiation safety, examination indications and other issues still lack comprehensive regulations and standards. Over the years, clinical guidelines and position statements for the rational use of CBCT examinations have been issued in the world, providing standardized instructions for local practitioners. This paper reviewed these guidelines to provide reference for the formulation of relevant guidelines in China.

Abstract
In basic experimental acupuncture research, rats are commonly used as laboratory animals. However, it is difficult for them to maintain a fixed posture. During electroacupuncture procedures, proper immobilization of rats is essential. Various methods of rat fixation are currently used, including anesthesia fixation, high-platform fixation, binding fixation, and fixation with a self-made rat coat. However, these methods have their limitations, which may affect the efficiency and operability of the experiment to some extent. This protocol introduces a method of suspending and fixing rats using rat clothes. Firstly, rats are clothed with rat jackets that match their body shape, taking advantage of their preference for darkness and burrowing. The needling operation can then be carried out after the rats have worn rat clothes. When suspended, the rats are relatively still, as their limbs cannot move. This fixation method offers not only economical and user-friendly benefits but also ensures a stable and reliable fixation of the rats in a comfortably relaxed position. It also effectively minimizes time consumption, experimental space, and manpower resources. Additionally, this method allows for the exposure of most acupoints used for acupuncture in rats. This article primarily concentrates on the device's composition, encompassing a specially designed rat jacket, an elevated fixation rack, and their connecting structures. Additionally, an illustrative example will be presented to demonstrate the application of the rat clothing-based suspension fixation method in rat electroacupuncture procedures.

Abstract
Biothiols and hydrogen sulfide, as critical sulfur-containing reactive substances, serve essential functions in various human pathological processes, making it challenging to simultaneously distinguish them due to their similar reactivity and structures (-SH). Here, we rationalized the development of a single-wavelength excitation near-infrared (NIR) fluorescence probe, FC-NBD, for distinguishing GSH/H2S and Cys/Hcy by separated fluorescence dual channels. In this probe, FC-NBD, composed of coumarin-benzopyrylium derivatives linked with nitro benzoxadiazole (NBD) via ether bonds, could quantitatively and selectively distinguish GSH/H2S and Cys/Hcy with a low limit of detection (LOD) of 0.199/0.177 μM and 0.106/0.076 μM, respectively. As expected, under single-wavelength excitation (470 nm), FC-NBD demonstrated distinctly separable green and NIR fluorescence emissions towards Cys/Hcy at 550 and 660 nm, but only exhibited a noticeable NIR fluorescence emission towards GSH/H2S at 660 nm. Moreover, FC-NBD could simultaneously visualize and discriminate GSH/H2S and Cys/Hcy in living cells as well as zebrafish through green and NIR channels at a single excitation wavelength.

Abstract
325 Background: In the pivotal CheckMate-649 trial, nivolumab in combination with chemotherapy (nivo + chemo), compared with chemotherapy alone (chemo), demonstrated superior efficacy in patients with previously untreated, advanced gastric, gastro-esophageal junction, or esophageal adenocarcinoma (collectively: gastroesophageal adenocarcinoma). This study aimed to describe the real-world patterns of use and effectiveness of nivo + chemo for first-line (1L) treatment of advanced gastroesophageal adenocarcinoma. Methods: Patients aged ≥18 years, newly diagnosed with unresectable, advanced or metastatic, HER2-negative gastroesophageal adenocarcinoma, who received nivo + chemo or chemo only between 4/1/2021 and 5/31/2022 were identified from the Flatiron Health database. Chemo regimens included FOLFOX or CAPEOX. Patients were followed from index date (start of 1L therapy) until death, loss of data availability, or end of data abstraction (05/31/2022), whichever occurred first. Results: 352 patients with advanced or metastatic gastroesophageal adenocarcinoma were eligible for the analysis (N=158 in the nivo + chemo group and N=194 in the chemo group). Baseline demographic and clinical characteristics were balanced between groups. Median follow-up was 3.6 (interquartile range [IRQ]: 1.5–8.1) months for nivo + chemo and 4.4 (IQR: 1.9–7.6) months for chemo. 44.3% of patients in the nivo + chemo group and 36.1% in the chemo group had <3 months of follow-up available. Median overall survival (OS) from index date was not reached (95% confidence interval [CI]: 9.0 months, –) in the nivo + chemo group and was 10.0 (95% CI: 8.5, 11.6) months in the chemo group. 43 patients (27.2%) in the nivo + chemo group died during the study period compared with 64 patients (33.0%) in the chemo group. Median progression-free survival (PFS) from index date in patients who received nivo + chemo was 6.9 (95% CI: 5.6, 8.2) months compared to 5.5 (95% CI: 4.8, 7.4) months in patients who received chemo. Similar trends were observed in the subgroup of patients with a PD L1 combined positive score (CPS) ≥1, while data on the CPS ≥5 subgroup were not mature enough for meaningful analyses. Conclusions: The addition of nivolumab to chemotherapy for 1L treatment of advanced or metastatic gastroesophageal adenocarcinoma showed a trend towards survival benefit in the real-world setting. The study is ongoing. Subsequent analyses will capture a larger patient sample and longer follow-up, and describe PD L1 CPS-based subgroups. [Table: see text]

Abstract
Purpose The aim of this study was to investigate the diagnostic ability and prognostic value of miR-342-3p in SLE patients by detecting the expression level of serum miR-342-3p in SLE patients. Patients and Methods The expression level of serum miR-342-3p in all subjects was determined by qRT-PCR technology, and the correlation of miR-342-3p with SLEDAI scores was evaluated using Spearman correlation coefficient. The diagnostic value of miR-342-3p in SLE was assessed using ROC curve. The prognostic value of miR-342-3p in SLE patients was analyzed by Kaplan-Meier survival curve and multivariate COX regression. Results The qRT-PCR results showed that the expression level of serum miR-342-3p in SLE patients was significantly lower than that in healthy controls (P < 0.001). Serum miR-342-3p expression level was negatively correlated with SLEDAI scores (r = - 0.810, P < 0.001). The ROC curve suggested that serum miR-342-3p expression level was discriminative between SLE patients and healthy controls. Survival analysis results indicated that SLE patients with low serum miR-342-3p expression had a higher probability of poor prognosis of SLE (Log rank P = 0.003). Conclusion The expression level of serum miR-342-3p was valuable in the diagnosis of SLE. Meanwhile, the low expression level of serum miR-342-3p was associated with the poor prognosis of SLE.

Abstract
DNA methyltransferase 3 A (DNMT3A) is the most frequently mutated gene in acute myeloid leukemia (AML). Although chemotherapy agents have improved outcomes for DNMT3A-mutant AML patients, there is still no targeted therapy highlighting the need for further study of how DNMT3A mutations affect AML phenotype. Here, we demonstrate that cell adhesion-related genes are predominantly enriched in DNMT3A-mutant AML cells and identify that graphdiyne oxide (GDYO) display an anti-leukemia effect specifically against these mutated cells. Mechanistically, GDYO directly interacts with integrin β2 (ITGB2) and c-type mannose receptor (MRC2), which facilitate the attachment and cellular uptake of GDYO. Furthermore, GDYO binds to actin and prevents actin polymerization, thus disrupting the actin cytoskeleton and eventually leading to cell apoptosis. Finally, we validate the in vivo safety and therapeutic potential of GDYO against DNMT3A-mutant AML cells. Collectively, these findings demonstrate that GDYO is an efficient and specific drug candidate against DNMT3A-mutant AML. DNA methyltransferase 3A, a mutated gene associated with hematologic malignancies in age-related clonal haematopoiesis lacks targeted therapies. Here, the authors screen carbon nanomaterials and find graphdiyne oxide binds to mutant cells and disrupts cellular processes with a therapeutic effect in vitro and in vivo.

Abstract
Hydrogels have been widely used in wet tissues. However, the insufficient adhesion of hydrogels for wound hemostasis remains a grand challenge. Herein, a facile yet effective strategy is developed to fabricate tough wet adhesion of hydrogen-bond-based hydrogel (PAAcVI hydrogel) using copolymerization of acrylic acid and 1-vinylimidazole in dimethyl sulfoxide followed by solvent exchange with water. The PAAcVI hydrogel shows equally robust adhesion (>400 J m-2) to both wet and dry tissues. Moreover, the PAAcVI hydrogel also exhibits strong long-term stable adhesion underwater and in various wet environments. Meanwhile, the adhesion of PAAcVI hydrogel can be adjusted through Zn2+-ion-mediated on-demand debonding, which makes it easy to peel off from the tissue reducing pain during dressing removal and avoiding secondary injury. The PAAcVI hydrogel displays efficient hemostasis in the mice-tail docking model and mice-liver bleeding model. This hydrogen-bond-based hydrogel shows tough wet adhesion, and its adhesion is controllable, demonstrating its promising application in moisture-resistant adhesives, medical adhesives, and hemostatic materials.

Abstract
Viral infections have been proven a severe threat to human beings, and the pandemic of Coronavirus Disease 2019 (COVID-19) has become a societal health concern, including mental distress and morbidity. Therefore, the early diagnosis and differentiation of viral infections are the prerequisite for curbing the local and global spread of viruses. To this end, carbon nanotubes (CNTs) based virus detection strategies are developed that provide feasible alternatives to conventional diagnostic techniques. Here in this review, an overview of the design and engineering of CNTs-based sensors for virus detection is summarized, followed by the nano-bio interactions used in developing biosensors. Then, we classify the viral sensors into covalently engineered CNTs, non-covalently engineered CNTs, and size-tunable CNTs arrays for viral detection, based on the type of CNTs-based nano-bio interfaces. Finally, the current challenges and prospects of CNTs-based sensors for virus detection are discussed.

Abstract
Chemotherapy induced peripheral neuropathy (CIPN) is a severe neurodegenerative disorder caused by chemotherapy drugs. Berberine is a natural monomer compound of Coptis chinensis, which has anti-tumor effect and can improve neuropathy through anti-inflammatory mechanisms. Transient receptor potential vanilloid (TRPV1) can sense noxious thermal and chemical stimuli, which is an important target for the study of pathological pain. In both vivo and in vitro CIPN models, we found that berberine alleviated peripheral neuropathy associated with dorsal root ganglia inflammation induced by cisplatin. We confirmed that berberine mediated the neuroinflammatory reaction induced by cisplatin by inhibiting the overexpression of TRPV1 and NF-κB and activating the JNK/p38 MAPK pathways in early injury, which inhibited the expression of p-JNK and mediated the expression of p38 MAPK/ERK in late injury in vivo. Moreover, genetic deletion of TRPV1 significantly reduced the protective effects of berberine on mechanical and heat hyperalgesia in mice. In TRPV1 knockout mice, the expression of NF-κB increased in late stage, and berberine inhibited the overexpression of NF-κB and p-ERK in late injury. Our results support berberine can reverse neuropathic inflammatory pain response induced by cisplatin, TRPV1 may be involved in this process.

Abstract
OBJECTIVE The aim of this study was to assess postoperative pregnancy outcomes in patients with different types of submucous myomas after hysteroscopic resection. MATERIALS AND METHODS This retrospective unicentric study used data from the electronic medical records system of the hospital. All patients (n = 77) who underwent hysteroscopy for submucous myomas between November 2010 and December 2018 were included. Patients were divided into three groups according to the myoma classification (G0, G1, and G2). Medical files were reviewed and phone questionnaires were conducted to evaluate demographic characteristics, clinical features, surgical treatment, and pregnancy outcomes. RESULTS The median age of the patients was 32 (30.0, 34.0) years. The myoma diameter was 2.9 (2.0, 3.8) cm. The operation duration was 50.0 (30.0, 75.0) min. There were 15 patients in Group G0, 20 patients in Group G1, and 37 patients in Group G2. Follow-up data were available for 65 of the 77 patients. The total pregnancy rate was 58 (89.2%) of 65. The live birth rate was 41 (70.7%) of 58. There was no significant difference in pregnancy rate (G0 100% vs. G1 76.5% vs. G2 91.2%; p = 0.097) or in live birth rates among the three groups (G0 78.6% vs. G1 53.8% vs. G2 74.2%; p = 0.325). CONCLUSION There was no difference in pregnancy outcome among the three types of submucosal myomas. Our results support the idea that hysteroscopic myomectomy is an effective option for submucous myomas with good long-term pregnancy outcomes.

Abstract
BACKGROUND Among the factors influencing academic performance (AP), individual differences at the trait level such as personality and emotional competences (EC) have been found to play a critical role, similarly to state variables such as perceived stress (PS). Participants And Procedure The aim of this study was to clarify whether the influence of personality (Big Five) and EC on AP (general point average) is direct and/or mediated via PS. 537 undergraduate students from a French university (112 male and 425 female, Mage = 19.84 years, SDage = 1.74 years, range = 18-30 years; first year: n = 293, 55%; second year: n = 162, 30%, third year: n = 82, 15%) filled out the test battery around three weeks before the final examination. RESULTS Path analysis showed that AP was directly predicted by conscientiousness (+), neuroticism (+), extraversion (-) and perceived stress (-), while perceived stress was predicted by neuroticism (+) and by intrapersonal EC (-). CONCLUSIONS The results illustrate the robust influence of conscientiousness on AP, while EC was not found to influence AP directly, but indirectly via its effect on PS.

Abstract
Body pigmentation is an important character of insects in adapting to biotic and abiotic environmental challenges. Additionally, based on the relative ease of screening, several genes involved in insect melanization have been used in classic genetic studies or as visual markers in constructing transgenic insects. Here, a homologue of the Bombyx mori melanization-inhibiting gene ebony, associated with the conversion of dopamine to N-β-alanyl dopamine, was identified in a global pest, Plutella xylostella. The CRISPR/Cas9 system was applied to generate multiple Pxebony knockout alleles which were crossed to produce a Pxebony knockout strain, showing darker pigmentation in larvae, pupae and adults, compared with wildtype. Interestingly, we observed that Pxebony heterozygotes displayed an intermediate darkened phenotype, indicating partial dominance between the knockout and wildtype alleles. The fitness costs of Pxebony deficiency were also assessed in the mutant strain, indicating that embryo hatchability and larval survival were significantly reduced, while the eclosion rate was not obviously affected. Our work provides a potential target for exploring CRISPR-based genetics-control systems in this economically important pest lepidopteran.

Abstract
BACKGROUND To analyze the relationship between the peripheral blood absolute lymphocyte count (ALC)/absolute monocyte count (AMC) ratio, soluble interleukin 2 receptor (sIL-2R) level, serum programmed cell death 1 (PD-1) level, and the prognosis of patients with diffuse large B-cell lymphoma (DLBCL). METHODS A total of 78 patients with DLBCL admitted to hospital and 30 healthy controls were enrolled as the case group and control group between August 2019 and June 2020, respectively. The ALC/AMC ratio and the levels of sIL-2R and serum PD-1 between the 2 groups and among patients with different prognoses were compared. The evaluation efficiency of these 3 factors for the prognosis of DLBCL patients was analyzed by receiver operating characteristic (ROC) curves. The risk factors affecting the 1-year survival rate were analyzed by the Cox hazard model. RESULTS The levels of sIL-2R, AMC, and PD-1 in the case group were significantly higher than those in the control group, while the ALC/AMC ratio was lower than that in the control group (P<0.05). The levels of sIL-2R and PD-1 in the poor prognosis group were significantly higher than those in the good prognosis group, while the ALC/AMC ratio was lower than that in the good prognosis group (P<0.05). The areas under the ROC curve (AUCs) of sIL-2R level, serum PD-1 level, and the ALC/AMC ratio in evaluating the prognosis of DLBCL patients were 0.805 (95% CI: 0.700-0.886), 0.825 (95% CI: 0.722-0.902), 0.792 (95% CI: 0.685-0.876), respectively. The critical values were 474.80 µg/L, 206.85 pg/mL and 3.01, respectively. The differences in the 1-year survival rate among DLBCL patients with different tumor sizes, B symptoms, sIL-2R levels, and ALC/AMC ratios were statistically significant (P<0.05). B symptoms (RR =1.721) and ALC/AMC ratio lower than 3.01 (RR =1.484) were independent influencing factors of the 1-year survival rate in DLBCL patients (P<0.05). CONCLUSIONS The ALC/AMC ratio, sIL-2R level, and serum PD-1 level can effectively assess the prognosis of DLBCL patients. B symptoms and ALC/AMC ratio lower than 3.01 are risk factors affecting the 1-year survival rate of patients.

Abstract
BACKGROUND Diabetes is a common metabolic disease with an increasing incidence in middle-aged and elderly people in recent years. Chronic hyperglycemia is the basic feature of diabetes, which can cause long-term damage to eyes, kidneys, nerves, heart, and blood vessels, resulting in functional decline or even failure. Glycosylated hemoglobin (HbA1c) can be used as an indicator of an individual's blood sugar status over the past 3 months; however, it is slightly affected by ischemic anemia. METHODS The data retrieval was performed in the databases of PubMed, Embase, and Ovid-Medline from their inception to April 2021, including keywords such as iron deficiency anemia (IDA), diabetes, HbA1c, immunoassay, and ion-exchange chromatography. After passing of sensitivity and heterogeneity analysis, Review Manager 5.3 was employed for meta-analysis. RESULTS A total of 6 studies were included in this paper. The analysis results showed that IDA could be considered to have an impact on HbA1c outcomes in non-diabetic populations. In people with diabetes, IDA is not thought to have an impact on HbA1c outcomes. DISCUSSION A total of 6 articles were included to discuss the effects of IDA on blood HbA1c in diabetic patients. The study found that when patients with diabetes were tested for blood sugar, the HbA1c did not accurately reflect their blood sugar control over the past 3 months.

Abstract
Background We have previously obtained a mouse anti-hepatitis B surface antigen (HBsAg) antibody E6F6 with long-lasting serum HBsAg clearance effects. The E6F6 epitope-based protein CR-T3-SEQ13 (HBsAg aa 113-135) vaccination therapy in cynomolgus monkeys induced long-term polyclonal antibodies-mediated clearance of HBsAg in the HBV transgenic (HBV-Tg) mice. Methods We isolated monoclonal antibodies from CR-T3-SEQ13 vaccinated cynomolgus monkeys, compared their therapeutic effects with E6F6, identified their epitopes on HBsAg, determined the pharmacokinetics and studied their physical property. Results A panel of anti-HBsAg mAbs was generated through memory B cell stimulatory culture. Two lead monkey-human chimeric antibodies, C1-23 and C3-23, effectively suppressed HBsAg and HBV DNA in HBV-Tg mice. The humanized antibodies and humanized-mouse reverse chimeric antibodies of two antibodies exhibited comparable HBsAg clearance and viral suppression efficacy as those versions of E6F6 in HBV-Tg mice. Humanized antibody hu1-23 exhibited more efficacy HBsAg-suppressing effects than huE6F6-1 and hu3-23 in HBV-Tg mice at dose levels of 10 and 20 mg/kg. Evaluation of the binding sites indicates that the epitope recognized by hu1-23 is located in HBsAg aa 118-125 and 121-125 for hu3-23. Physical property study revealed that hu1-23 and hu3-23 are stable enough for further development as a drug candidate. Conclusions Our data suggest that the CR-T3-SEQ13 protein is a promising HBV therapeutic vaccine candidate, and hu1-23 and hu3-23 are therapeutic candidates for the treatment of chronic hepatitis b. Moreover, the generation of antibodies from the epitope-based vaccinated subjects may be an alternative approach for novel antibody drug discovery.

Abstract
Heart rate variability (HRV) biofeedback, referring to slow-paced breathing (SPB) realized while visualizing a heart rate, HRV, and/or respiratory signal, has become an adjunct treatment for a large range of psychologic and medical conditions. However, the underlying mechanisms explaining the effectiveness of HRV biofeedback still need to be uncovered. This study aimed to disentangle the specific effects of HRV biofeedback from the effects of SPB realized alone. In total, 112 participants took part in the study. The parameters assessed were emotional (valence, arousal, and control) and perceived stress intensity as self-report variables and the root mean square of the successive differences (RMSSD) as a physiologic variable. A main effect of condition was found for emotional valence only, valence being more positive overall in the SPB-HRVB condition. A main effect of time was observed for all dependent variables. However, no main effects for the condition or time x condition interaction effects were observed. Results showed that for PRE and POST comparisons (referring, respectively, to before and after SPB), both SPB-HRVB and SPB-NoHRVB conditions resulted in a more negative emotional valence, lower emotional arousal, higher emotional control, and higher RMSSD. Future research might investigate psychophysiological differences between SPB-HRVB and SPB-NoHRVB across different time periods (e.g., long-term interventions), and in response to diverse psychophysiological stressors.

Abstract
As a toxic substance, mercury can easily cause harm to organisms and humans. The development of methods that allow rapid detection of low concentrations of mercury ions has a positive effect on the natural environment and human health. The fluorescent probe RBSH reported in this paper has a detection limit as low as 5.9 nM, and a fast response time and allows naked eye detection. We characterized its structure by nuclear magnetic resonance and mass spectrometry, and explored the response mechanism of the probe using Job's plot, and 1H NMR and mass spectrometry. UV-vis spectrophotometry and fluorescence spectroscopy show the excellent optical properties of the probe RBSH. The low toxicity and high cell penetration capacity demonstrated by the cellular assay open up the possibility of biological experiments. By selecting hosts (natural water samples, soybean plants and zebrafish) where mercury ions are likely to be present in the biological chain for low concentration Hg2+ detection, the results all demonstrated the excellent performance of the probe RBSH.

Abstract
Background/objectives According to the reported cases, more than 100 athletes were infected with severe acute respiratory syndrome coronavirus 2 in March 2020 alone, and this has created an increased interest in the effect of coronavirus disease (COVID-19) on athletes. This promoted us to study the spread of COVID-19 in athletes and formulate prevention strategies. Methodology We collected and analyzed the demographic information, such as nationality, sex, age, name, sport played, sport level, source and cause of infection, date of symptoms onset or confirmation of positive status, date of recovery, location of infection contraction, symptoms, and the people infected by the contracted athletes, of 521 infected athletes worldwide, as of the end of July, 2020. Results The cohort comprised 95.49% male athletes; 57.2% were aged 19–35 years, with the average age 23 years. Most of these cases emerged in March 2020 (27.3%) and June 2020 (30.1%), 90.8% of cases were active athletes and 74.2% were professional players, 45.2% of infected athletes exhibited mild symptoms and 30.6% of them were asymptomatic; however, 23.1% of the cases died, including cases aged less than 40 years. Most infected athletes represented soccer (46.6%), football (15.9%), and basketball (10.9%). Most of the infected athletes were from the United States, Western Europe, and Eastern Asia. The athletes primarily contracted the infection in the United States, Western Europe, and Japan. The spread of COVID-19 in these athletes primarily occurred during training- and game-related activities. More than 60% of the infected athletes were unaware of their source of infection. Conclusion It found that the halting of training and matches, isolation of athletes at home, and timely testing can effectively control the spread of COVID-19 among athletes, and it is recommended that athletes discontinue international travel, especially to countries with a high epidemic risk.

Abstract
Adenomyosis (AM) is a disease in which endometrial tissue invades the myometrium and has a 10–60% prevalence in reproductive-aged women. TSC2 regulates autophagy via mTOR1 signalling in colorectal cancer and endometrial carcinoma. Dysregulation of autophagy is implicated in adenomyosis pathogenesis. However, whether TSC2 participates in adenomyosis via autophagy remains obscure. Here, we found that the expression of TSC2 in adenomyosis was significantly decreased than that in normal endometrium during the secretory phase. Moreover, TSC2 and autophagy marker expression was significantly lower in ectopic lesions than in eutopic samples. TSC2 downregulation inhibited autophagy through mTOR1 signalling pathway activation in endometrial cells, leading to excessive proliferation, migration, and EMT; TSC2 overexpression induced the opposite effects. Rapamycin treatment suppressed cell proliferation, migration and EMT in the absence of TSC2. In parallel, an autophagy-specific inhibitor (SAR-405) restored migration and EMT under rapamycin treatment in TSC2-knockdown Ishikawa cells. Finally, SAR-405 treatment promoted EMT and migration of overexpressing cells. Collectively, our results suggest that TSC2 controls endometrial epithelial cell migration and EMT by regulating mTOR1-autophagy axis activation and that hypo-expression of TSC2 in the endometrium might promote adenomyosis.

Abstract
Nanomaterial-biology interaction is the critical step in the fate of biomedical nanomedicines, influencing the consequent biological outcomes. Herein, we present two-dimensional carbon-based nanomaterials-graphdiyne oxide (GDYO) nanosheets that interact with an intracellular protein corona consisting of signal transducer and activator of transcription 3 (STAT3), inducing the reeducation of immunosuppressive macrophages. The interaction at the GDYO-STAT3 interface, driven by structure matching, hydrogen bonding, and salt bridges, simultaneously triggers the immune response in the tumor microenvironment, facilitating cancer immunotherapy. For the first time, our data reveal an interaction mechanism between the nanoparticle-protein interfaces inevitably formed inside the cells that determines the macrophage phenotype. Our results suggest that GDYO nanosheets could be applied for local immunomodulation due to their function and structural organization of the intracellular protein corona occurred inside macrophages.

Abstract
Melanoma as a very aggressive type of cancer is still in urgent need of improved treatment. Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) and arginine deiminase (ADI-PEG20) are two of many suggested drugs for treating melanoma. Both have shown anti-tumor activities without harming normal cells. However, resistance to both drugs has also been noted. Studies on the mechanism of action of and resistance to these drugs provide multiple targets that can be utilized to increase the efficacy and overcome the resistance. As a result, combination strategies have been proposed for these drug candidates with various other agents, and achieved enhanced or synergistic anti-tumor effect. The combination of TRAIL and ADI-PEG20 as one example can greatly enhance the cytotoxicity to melanoma cells including those resistant to the single component of this combination. It is found that combination treatment generally can alter the expression of the components of cell signaling in melanoma cells to favor cell death. In this paper, the signaling of TRAIL and ADI-PEG20-induced arginine deprivation including the main mechanism of resistance to these drugs and exemplary combination strategies is discussed. Finally, factors hampering the clinical application of both drugs, current and future development to overcome these hurdles are briefly discussed.

Abstract
Abstract
Arginine (Arg) deprivation can inhibit tumors which do not express argininosuccinate synthetase (ASS), a key enzyme for synthesis of Arg. Arg deiminase (ADIPEG20) has shown antitumor activity in such tumors, including melanoma and mesothelioma. Resistance to this treatment occurs due to re-expression of ASS. We have shown that this is mediated via cMyc (positive regulator) and HIF1α ( negative regulator ). Arg starvation rapidly induces chromatin remodeling complex P300-HDAC2-Sin3A which epigenetically deacetylates H3K14ac and H3K27ac at the ASS promoter. Following the PHD2-derived HIF1α-degrading system, the promoter-bound HIF1α is degraded (Sci Rep 7:10814). This allows cMyc (an E-Box binder), to turn on ASS. Arg starvation rapidly triggers externalization of Gas6 to interact with its receptor tyrosine kinase (RTK) Axl. This activates the downstream Ras-PI3K/AKT/GSK3β pathway, resulting in stabilization of cMyc. However, this activation also turns on PDL1 gene expression. This is not surprising since cMyc has been shown to bind to PDL1 promoter and increase its expression. Thus, re-expression of ASS also leads to PDL1 expression. We studied these findings in two other cell lines, Mel114 and Skmel2, and obtained similar results, Interestingly, in three cell lines with high levels of antiapoptotic protein Bcl-2, Arg starvation only leads to growth inhibition, with only less than 2 fold increase in ASS and no PDL1 expression. These results suggest that increased Bcl-2 expression negates the necessity to increase PDL1 and ASS to prevent cell death from nutritional stress. In contrast, transfection of ASS in A2058, A375, Mel1220 and SkMel2 will only confer resistance to Arg starvation, and does not affect PDL1, Bcl2 expression or other alterations in PI3K/AKT pathway. Furthermore, in samples from patients who failed ADIPEG20 due to increased ASS expression, the primary cultures or re-biopsy tumor also exhibited high levels of PDL1 expression, which most likely will make them susceptible to anti PDL1 treatment. On the other hand, six primary cultures derived from patients who failed BRAF/MEK inhibitor (BMR) also showed low levels of ASS and increase in PDL1 expression (1.5-4 fold increase both in mRNA and proteins level compared to their parental cells). These results also applied to 5 pairs of BMR cell lines (A375/BMR, A2058/BMR, Skmel2/BMR, UACC62/BMR, MelRR/BMR). These cells also are very susceptible to combination of ADIPEG20 and PD-L1 treatment. Overall, our data suggest that combination of Arg deprivation and check point inhibitors is effective in patients whose tumors do not express ASS and as salvage therapy for BRAF/MEK inhibitor resistant patients.

Abstract
Designing emotional intelligence training programs requires first testing the effectiveness of techniques targeting its main dimensions. The aim of this study was to investigate the effects of a brief slow-paced breathing (SPB) exercise on psychophysiological variables linked to emotion regulation, namely cardiac vagal activity (CVA), as well as perceived stress intensity, emotional arousal, and emotional valence. A total of 61 participants completed a 5-min SPB exercise and a control condition of a 5-min rest measurement. CVA was indexed with the root mean square of successive differences (RMSSD). Participants were also asked to rate their perceived stress intensity, emotional arousal, and emotional valence. Results showed that CVA was higher during SPB in comparison to the control condition. Contrary to our hypothesis, perceived stress intensity and emotional arousal increased after SPB, and perceived emotional valence was less positive after SPB. This could be explained by experiencing dyspnea (i.e., breathing discomfort), and the need to get acclimatized to SPB. Consequently, we may conclude that although physiological benefits of SPB on CVA are immediate, training may be required in order to perceive psychological benefits.

Abstract
MicroRNAs (miRNAs) are endogenous short non-encoding RNAs which play a critical role on the output of the proteins, and influence multiple biological characteristics of the cells and physiological processes in the body. Mesenchymal stem/stromal cells (MSCs) are adult multipotent stem cells and characterized by self-renewal and multidifferentiation and have been widely used for disease treatment and regenerative medicine. Meanwhile, MSCs play a critical role in maintaining homeostasis in the body, and dysfunction of MSC differentiation leads to many diseases. The differentiation of MSCs is a complex physiological process and is the result of programmed expression of a series of genes. It has been extensively proven that the differentiation process or programmed gene expression is also regulated accurately by miRNAs. The differentiation of MSCs regulated by miRNAs is also a complex, interdependent, and dynamic process, and a full understanding of the role of miRNAs will provide clues on the appropriate upregulation or downregulation of corresponding miRNAs to mediate the differentiation efficiency. This review summarizes the roles and associated signaling pathways of miRNAs in adipogenesis, chondrogenesis, and osteogenesis of MSCs, which may provide new hints on MSCs or miRNAs as therapeutic strategies for regenerative medicine and biotherapy for related diseases.

Abstract
Radioresistance is an important challenge for clinical treatments. The main causes of radioresistance include hypoxia in the tumor microenvironment, the antioxidant system within cancer cells, and the upregulation of DNA repair proteins. Here, a multiple radiosensitization strategy of high-Z-element-based radiation enhancement is designed, attenuating hypoxia and microRNA therapy. The novel 2D graphdiyne (GDY) can firmly anchor and disperse CeO2 nanoparticles to form GDY-CeO2 nanocomposites, which exhibit superior catalase-mimic activity in decomposing H2 O2 to O2 to significantly alleviate tumor hypoxia, promote radiation-induced DNA damage, and ultimately inhibit tumor growth in vivo. The miR181a-2-3p (miR181a) serum levels in patients are predictive of the response to preoperative radiotherapy in locally advanced esophageal squamous cell carcinoma (ESCC) and facilitate personalized treatment. Moreover, miR181a can act as a radiosensitizer by directly targeting RAD17 and regulating the Chk2 pathway. Subsequently, the GDY-CeO2 nanocomposites with miR181a are conjugated with the iRGD-grafted polyoxyethylene glycol (short for nano-miR181a), which can increase the stability, efficiently deliver miR181a to tumor, and exhibit low toxicity. Notably, nano-miR181a can overcome radioresistance and enhance therapeutic efficacy both in a subcutaneous tumor model and human-patient-derived xenograft models. Overall, this GDY-CeO2 nanozyme and miR181a-based multisensitized radiotherapy strategy provides a promising therapeutic approach for ESCC.

Abstract
The autoimmune diseases are characterized by overactivation of immune cells, chronic inflammation, and immune response to self-antigens, leading to the damage and dysfunction of multiple organs. Patients still do not receive desired clinical outcomes while suffer from various adverse effects imparted by current therapies. The therapeutic strategies based on mesenchymal stromal cell (MSC) transplantation have become the promising approach for the treatment of autoimmune diseases due to the immunomodulation property of MSCs. MSCs derived from perinatal tissues are collectively known as perinatal MSCs (PMSCs), which can be obtained via painless procedures from donors with lower risk of being contaminated by viruses than those MSCs from adult tissue sources. Therefore, PMSCs may be the ideal cell source for the treatment of autoimmune diseases. This article summarizes recent progress and possible mechanisms of PMSCs in treating autoimmune diseases in animal experiments and clinical studies. This review also presents existing challenges and proposes solutions, which may provide new hints on PMSC transplantation as a therapeutic strategy for the treatment of autoimmune diseases.

Abstract
Interleukin 12 (IL12) is a potent pro-inflammatory chemokine with multifunction, including promoting cytotoxic T-cell-mediated killing of cancer cells. IL12-based cancer gene therapy can overcome IL12's life-threatening adverse effects, but its clinical translation has been limited by the lack of systemic gene-delivery vectors capable of efficiently transfecting tumors to produce sufficient local IL12. Macrophages inherently excrete IL12, and tumor-associated macrophages (TAMs) are the major tumor component taking up a large fraction of the vectors arriving in the tumor. It is thus hypothesized that a gene vector efficiently transfecting both cancer cells and TAMs would make the tumor to produce sufficient IL12; however, gene transfection of TAMs is challenging due to their inherent strong degradation ability. Herein, an IL12 gene-delivery vector is designed that efficiently transfects both cancer cells and TAMs to make them as a factory for IL12 production, which efficiently activates anticancer immune responses and remodels the tumor microenvironment, for instance, increasing the M1/M2 ratio by more than fourfold. Therefore, the intravenously administered vector retards tumor growth and doubles survival in three animal models' with negligible systemic toxicities. This work reports the first nonviral IL12 gene delivery system that effectively makes use of both macrophages and tumor cells.

Abstract
Odorant binding proteins (OBPs) are critical components in insect olfactory systems where they bind, solubilize and transport odorant molecules to receptors. Here, we cloned three OBPs (PxylGOBP1, PxylGOBP2 and PxylOBP24) from the diamondback moth, Plutella xylostella, one of the most destructive pests of cruciferous crops. These three OBPs were expressed in Escherichia coli as recombinant proteins, purified and characterized by fluorescence binding assays with 39 ligands including sex pheromone and plant-derived chemical compounds. PxylGOBP1 and PxylGOBP2 showed significantly different binding affinities to theses ligands, suggesting distinct binding preferences of these two general odorant binding proteins. PxylOBP24 showed no or extremely low binding activities to selected ligands, suggesting it may be involved in non-olfactory functions. Circular dichroism spectral results demonstrated that PxylGOBP1 and PxylGOBP2 shared similar secondary structures while PxylOBP24 was significantly different. This study improves our knowledge of insect OBPs, which will assist in a better understanding of insect olfactory system and developing more environmentally friendly pest control strategies for P. xylostella.

Abstract
AIM To evaluate the clinical efficacy and safety of laparoscopic adenomyomectomy combined with intraoperative replacement of levonorgestrel-releasing intrauterine system (LNG-IUS) in the treatment of symptomatic adenomyosis. METHODS This is a case-series study in a university medical center. A total of 52 patients with symptomatic adenomyosis were treated by laparoscopic adenomyomectomy combined with intraoperative replacement of LNG-IUS from January 2015 to July 2018. Visual analog scale, menstrual flow and uterine volume were compared before and after the surgery (3, 12 and 24 months). Meanwhile, LNG-IUS-induced adverse reactions (e.g. irregular vaginal bleeding, amenorrhea, expulsion, and perforation) were also recorded. RESULTS All operations were successfully completed via laparoscopy without conversion to laparotomy. No severe complications were noted during the surgical procedure or follow-up period. The mean postoperative visual analog scale and menstrual flow scores and the volume of the uterus were significantly decreased (all P < 0.001) at 3, 12, and 24 months postoperatively, compared with preoperative scores. The clinical effective rates among the patients with dysmenorrhea were 98%, 96% and 96% at 3, 12 and 24 months after the operation, respectively. And the clinical effectiveness rate of menorrhagia was 97.6%, 95.2% and 95.2% at 3, 12 and 24 months after treatment, respectively. Among all related adverse reactions, amenorrhea was the most common (n = 12, 23.1%). There was one case of LNG-IUS perforation (1.9%) and two cases of expulsion (3.8%). CONCLUSION Laparoscopic adenomyomectomy combined with intraoperative replacement of LNG-IUS is a novel and effective conservative surgical procedure for symptomatic adenomyosis treatment.

Abstract
OBJECTIVE Exercise is one of the most potent strategies available to support cognitive health with age, yet substantial variability exists. Sexual dimorphism is evident for brain and immune functioning, the latter being implicated as important pathway for exercise. We examined the moderating role of sex on the relationship between physical activity and systemic inflammatory and brain health outcomes in support of more personalized approaches to behavioral interventions. METHODS Our discovery cohort included 45 typically aging women matched on age (±5y) and education (±2y) to 45 men (mean age = 72.5; Clinical Dementia Rating = 0) who completed self-reported current physical activity (Physical Activity Scale for Elderly), blood draw, neuropsychological evaluation, and brain MRI. An independent sample of 45 typically aging women and 36 men who completed the same measures comprised a replication cohort. Plasma was analyzed for 11 proinflammatory cytokine and chemokine markers via MesoScale Discovery. RESULTS Discovery cohort: Reported physical activity did not differ between sexes (150 vs. 157, p = 0.72). There was a significant interaction between sex and physical activity on chemokine markers MDC, MIP-1b, MCP-4, and eotaxin-3 (ps < 0.03), with a similar trend for MCP-1 and INFγ (ps < 0.09). Men who reported greater activity demonstrated lower inflammatory markers, an effect attenuated-to-absent in women. An interaction between sex and physical activity was also observed for parahippocampal volumes (p = 0.02) and cognition (processing speed and visual memory; ps < 0.04). Again, the beneficial effect of physical activity on outcomes was present in men, but not women. Replication cohort analyses conferred a consistent effect of sex on the relationship between physical activity and immune markers; models examining neurobehavioral outcomes did not strongly replicate. Across cohorts, post-hoc models demonstrated an interaction between sex and activity-related inflammatory markers on total gray matter volume and visual memory. Men with higher inflammatory markers demonstrated poorer brain structure and function, whereas inflammatory markers did not strongly relate to neurobehavioral outcomes in women. CONCLUSIONS Greater physical activity was associated with lower markers of inflammation in clinically normal older men, but not women - an effect consistently replicated across cohorts. Additionally, men appeared disproportionately vulnerable to the adverse effects of peripheral inflammatory markers on brain structure and function compared to women. Immune activation may be a male-specific pathway through which exercise confers neurobehavioral benefit.

Abstract
AIMS This study evaluated the effects of exogenous lactic acid bacteria (LAB) on silage fermentation and bacterial community of reed canary grass (RCG) straw. METHODS AND RESULTS The leaf, stem and whole crop of RCG straw were separately ensiled in small bag silos, without (control) or with inoculation of two exogenous LAB (LP, Lactobacillus plantarum; LB, Lactobacillus buchneri), and stored at ambient temperature of <20°C. Inoculation of exogenous LAB decreased (P < 0·05) bacterial alpha diversity and shifted (P < 0·05) bacterial community compositions, but did not change (P> 0·05) the relative abundance of Lactobacillus. Particularly, inoculation of LB increased (P < 0·05) acetic acid and propionic acid contents, decreased (P < 0·05) butyric acid (BA) and ammonia-N contents, separated (P < 0·05) the bacterial community in silage. However, the exogenous LAB inoculated silages were characterized by main distribution of yeasts, presence of undesirable bacterial genera such as Clostridium and high levels of BA and ammonia-N. CONCLUSION Inoculation of exogenous LAB exerted a limited influence on the silage fermentation and bacterial community compositions of RCG straw on the Qinghai-Tibetan Plateau. SIGNIFICANCE AND IMPACT OF THE STUDY Commercial LAB inoculants are not always efficient on enhancing silage quality and stability. Thus, an alternative additive for inhibiting undesirable microbes during storage is important to improve RCG silage quality on the Qinghai-Tibetan Plateau.

Abstract
This study aimed to investigate the associations between individual difference factors (chronotype, Big Five, emotional competences) and perceived stress in French university students. In total, 362 students agreed to take part (M age = 20.19 ± 1.75 years). Participants completed the Caen Chronotype Questionnaire, Big Five Inventory, the Profile of Emotional Competences, and the Perceived Stress Scale. Results showed that chronotype amplitude (+), eveningness chronotype (+), neuroticism (+), conscientiousness (-), and intrapersonal emotional competences (-) were important for perceived stress. These findings have theoretical and practical implications in terms of identifying students who might benefit most from stress management interventions.

Abstract
Metal ions are essential components that help maintain the processes of normal life, and they can be used to fabricate self-assembled building blocks for peptide derivatives, proteins and nucleic acids. Here, we have developed a novel strategy to construct supramolecular hydrogels modulated using metal cations. Upon introducing a variety of metal ions into aqueous solutions of a gelator (naproxen-FF), including a nonsteroidal anti-inflammatory drug (NSAID) and dipeptide, we obtain stable hydrogels under neutral or alkaline conditions. It is found that these hydrogels with three-dimensional nanofiber networks exhibit excellent mechanical properties and thixotropy, as well as superb responsivity to multiple metal ions. Due to the significance of potassium ions in biological processes, the K-triggered hydrogel has been chosen as a model, and its self-assembly mechanism has been explored via various spectral analysis processes. In addition, the self-assembly performances of peptides are significantly affected by the chemical structures of the gelator molecules. This work provides deep insight into the aggregation mechanism of dipeptide-conjugating drug molecules through introducing a variety of metal ions, laying the foundation for further biological applications.

Abstract
We have reported that E6F6, a mouse monoclonal antibody, is a promising treatment option for patients with chronic hepatitis B (CHB). A humanized E6F6 antibody B11 with affinity loss was obtained by CDR-grafting approach. To address this issue, in silico affinity maturation through scanning mutagenesis using CHARMM force field methods was performed on an predicted immune complex model of the B11:HBsAg. We chose four variants with top increased interaction energy for further characterization. The antibody huE6F6-1 within two point mutations (Heavy Chain: Asp65Val; His66Leu) was identified to restore the parental antibody's high binding affinity, neutralization activity, and potent efficacy of viral suppression in vivo. Crystal structure (1.8 Å resolution) based molecular docking proved more stabilized and compact hydrogen bond interactions formed in huE6F6-1.The smaller and dispersed HBV immune complexes of huE6F6-1 by electron microscopy suggested it will have the same therapeutic efficacy as the parental E6F6 mAb. Preclinical study and pharmacokinetics of huE6F6-1 demonstrated that it is a stable and desirable lead candidate to improve the clinical management of CHB. Notably, our structure guided approach may facilitate the humanization and affinity maturation of other rodent antibody candidates during drug development.

Abstract
Mesenchymal stem cells (MSCs) have proven powerful potential for cell-based therapy both in regenerative medicine and disease treatment. Human umbilical cords and exfoliated deciduous teeth are the main sources of MSCs with no donor injury or ethical issues. The goal of this study was to investigate the differences in the biological characteristics of human umbilical cord mesenchymal stem cells (UCMSCs) and stem cells from human exfoliated deciduous teeth (SHEDs). UCMSCs and SHEDs were identified by flow cytometry. The proliferation, differentiation, migration, chemotaxis, paracrine, immunomodulatory, neurite growth-promoting capabilities, and acetaldehyde dehydrogenase (ALDH) activity were comparatively studied between these two MSCs in vitro. The results showed that both SHEDs and UCMSCs expressed cell surface markers characteristic of MSCs. Furthermore, SHEDs exhibited better capacity for proliferation, migration, promotion of neurite growth, and chondrogenic differentiation. Meanwhile, UCMSCs showed more outstanding adipogenic differentiation and chemotaxy. Additionally, there were no significant differences in osteogenic differentiation, immunomodulatory capacity, and the proportion of ALDHBright compartment. Our findings indicate that although both UCMSCs and SHEDs are mesenchymal stem cells and presented some similar biological characteristics, they also have differences in many aspects, which might be helpful for developing future clinical cellular therapies.
