Abstract
Currently, high-performance polymerized small-molecule acceptors (PSMAs) based on ADA-type SMAs are still rare and greatly demanded for polymer solar cells (PSCs). Herein, two novel regioregular PSMAs (PW-Se and PS-Se) are designed and synthesized by using centrosymmetric (linear-shaped) and axisymmetric (banana-shaped) ADA-type SMAs as the main building blocks, respectively. It is demonstrated that photovoltaic performance of the PSMAs can be significantly improved by optimizing the configuration of ADA-type SMAs. Compared to the axisymmetric SMA-based polymer (PS-Se), PW-Se using a centrosymmetric SMA as the main building block exhibits better backbone coplanarity thereby resulting in bathochromically shifted absorption with a higher absorption coefficient, tighter interchain π-π stacking, and more favorable blend film morphology. As a result, enhanced and more-balanced charge transport, better exciton dissociation, and reduced charge recombination are achieved for PW-Se-based devices with PM6 as polymer donor. Benefiting from these positive factors, the optimal PM6:PW-Se-based device exhibits a higher power conversion efficiency (PCE) of 15.65% compared to the PM6:PS-Se-based device (8.90%). Furthermore, incorporation of PW-Se as a third component in the binary active layer of PM6:M36 yields ternary devices with an outstanding PCE of 18.0%, which is the highest value for PSCs based on ADA-type SMAs, to the best of the knowledge.

Abstract
BACKGROUND In this study, we aimed to identify the risk factors for new-onset atrial fibrillation (NOAF) after postcoronary intervention in patients with acute myocardial infarction (AMI) and to establish a nomogram prediction model. METHODS The clinical data of 506 patients hospitalized for AMI from March 2020 to February 2023 were retrospectively collected, and the patients were randomized into a training cohort (70%; n = 354) and a validation cohort (30%; n = 152). Independent risk factors were determined using least absolute shrinkage and selection operator and multivariate logistic regression. Predictive nomogram modeling was performed using R software. Nomograms were evaluated based on discrimination, correction, and clinical efficacy using the C-statistic, calibration plot, and decision curve analysis, respectively. RESULTS The multivariate logistic regression analysis showed that P-wave amplitude in lead V1, age, and infarct type were independent risk factors for NOAF, and the area under the receiver operating characteristic curve of the training and validation sets was 0.760 (95% confidence interval [CI] 0.674-0.846) and 0.732 (95% CI 0.580-0.883), respectively. The calibration curves showed good agreement between the predicted and observed values in both the training and validation sets, supporting that the actual predictive power was close to the ideal predictive power. CONCLUSIONS P-wave amplitude in lead V1, age, and infarct type were independent risk factors for NOAF in patients with AMI after intervention. The nomogram model constructed in this study can be used to assess the risk of NOAF development and has some clinical application value.

Abstract
Abstract
Introduction/Objective
Rhabdomyosarcoma (RMS), mesenchymal derived tumor, is predominantly diagnosed in the pediatric population but may present at any age. Less than 1% of all adult solid malignant cancers are sarcomas, and rhabdomyosarcoma comprises <0.001% of adult sarcomas. Primary intracranial RMS is rare and has been reported in the cerebrum, cerebellum, brainstem, and the meninges. The occurrence of a primary intracranial RMS arising from the pineal gland is exceedingly rare.
Methods/Case Report
An adult male presented to the ED with complaint of several months of headaches, progressive confusion, forgetfulness and most recently difficulty in finding words. CT scan showed a large mass arising from the pineal gland causing obstructive hydrocephalus. Subsequently, the patient underwent excisional biopsy. The histopathology examination revealed small round basophilic cells and large polygonal cells with large eccentric nuclei and prominent nucleoli, abundant eosinophilic cytoplasm containing globular paranuclear eosinophilic inclusions, characteristic of rhabdoid cells. Immunohistochemical (IHC) showed tumor cells are positive for Desmin, MyoD1, CK8/18, INI1 (hSNF5; SMARCB1) with retained nuclear expression and faint positivity for Synaptophysin and focally positivity for Neurofilament. The tumor cells showed negative staining for Pankeratin, SOX10, Oct4, SALL4, INSM1, LCA AND CD30, which excluded the possibility of Germ cell tumor and Pineoblastoma. The case was finalized as primary malignant neoplasm, consistent with Embryonal Rhabdomyosarcoma of pineal gland.
Results (if a Case Study enter NA)
NA
Conclusion
This case highlights the rare occurrence of rhabdomyosarcoma originating from the pineal gland in an adult male. Morphologic and immunohistochemical findings were consistent with embryonal rhabdomyosarcoma. Since primary rhabdomyosarcoma of the pineal gland is rare, this case contributes to the limited body of literature on such cases. It underscores the importance of considering unusual entities in intracranial tumors. The distinct morphology and the use of IHC aids in diagnosing this rare entity.

Abstract
Gut microbiota (GM) dysbiosis has been increasingly associated with Alzheimer's disease (AD). However, the association between APOE4, the most common genetic risk factor for sporadic AD, and GM in AD remains unclear. In this study, we conducted a comparative analysis of the GM of participants from China and the USA, with and without APOE4 genes and with or without AD (67 AD cases, 67 control cases). Our results revealed that the GM alpha diversity was not different between groups (AD_APOE4, Control_APOE4, AD_non-APOE4, and Control_non-APOE4) (419.031 ± 143.631 vs 391.091 ± 126.081, 351.086 ± 169.174 and 386.089 ± 177.200, respectively. P > 0.05). Interestingly, individuals in the AD_APOE4 group had different bacterial compositions and bacterial biomarkers. The Kruskal-Wallis rank sum test indicated that the abundances of many bacterial species in the AD_APOE4 patients differed from those in control individuals, including decreases in unclassified_g__Escherichia-Shigella (1.763 ± 6.73, 4.429 ± 11.13, 8.245 ± 16.55, and 5.69 ± 13.91 in four groups, respectively; P < 0.05), and unclassified_g_Clostridium_sensu_stricto_1 (0.1519 ± 0.348, 2.502 ± 5.913, 0.5146 ± 0.9487, 1.063 ± 3.428 in four groups, respectively; P < 0.05), and increases in gut_metagenome_g_Faecalibacterium (2.885 ± 4.47, 2.174 ± 3.957, 0.5765 ± 1.784, 1.582 ± 2.92 in four groups, respectively. P < 0.01) and unclassified_g_Bacteroides (3.875 ± 3.738, 2.47 ± 2.748, 2.046 ± 3.674, 3.206 ± 3.446 in four groups, respectively; P < 0.05). In the KEGG pathway level 2 analysis, we identified three significant differences in relative abundances of predicted functions between AD_APOE4 and AD_non-APOE4_carrier groups: neurodegenerative diseases (0.0007 ± 0.0005 vs 0.0009 ± 0.0004; P < 0.01), metabolism (0.0240 ± 0.0003 vs 0.0250 ± 0.0003; P < 0.05), and biosynthesis of other secondary metabolites (0.0094 ± 0.0002 vs 0.0090 ± 0.0002; P < 0.05). Receiver operating characteristic curves further demonstrated an area under the curve (AUC) of 0.74 for the discrimination of AD_APOE4_carrier and AD_non-APOE4_carrier individuals.

Abstract
Abstract
Introduction/Objective
Acute respiratory distress syndrome (ARDS) is a type of respiratory failure caused by diffuse injury to surfactant-producing cells and fluid buildup in the alveoli. ARDS impairs lung's ability and is potentially fatal. Tumor lysis syndrome is an oncologic emergency mostly triggered by the initiation of chemotherapy causing life- threatening metabolic cascades even with preventable therapies.
Methods/Case Report
We report an autopsy case of a 71-year-old male who was referred to the Emergency Department with complaints of poor appetite, dizziness, nausea. He was found to have a white blood cell count over 1,000,000, with hemoglobulin of 7.7, platelet count of 95, uric acid 11.5, LDH 486. He was diagnosed with mantle cell lymphoma (MCL) involving peripheral blood and received Allopurinol for tumor lysis syndrome prophylaxis. He started to receive Rituximab. Soon after, he became lethargic and more hypoxemic and needed intubation. But he became pulseless and he did not recover.
Results (if a Case Study enter NA)
The autopsy revealed an extensive spread of the lymphoma to multi-organs, including the esophagus, spleen, liver, kidney, heart, prostate. Bone marrow and lymph nodes were diffusely infiltrated by atypical medium lymphocytes. Stains on lymph nodes show the atypical lymphocytes are positive for CD20, CD5, Cyclin D1, Bcl2, negative for CD23, Bcl6, with a Ki-67 proliferative index around 40%, consistent with MCL. The patient's lungs were heavy and microscopic examination confirmed ARDS.
Conclusion
We, here describe a patient with MCL who developed tumor lysis syndrome with Rituximab monotherapy and died of ARDS shortly after. It's rarely reported that tumor lysis syndrome results in fatal ARDS.

Abstract
Background Gut and oral microbes form complex communities and play key roles in co-evolution with their hosts. However, little is understood about the bacterial community in lizards. Results In this study, we investigated the gut and oral bacterial communities in Japalura sensu lato from Sichuan Province, China, using 16S rRNA gene sequencing. Results showed that Bacteroidota (36.5%) and Firmicutes (32.8%) were the main phyla in the gut, while Proteobacteria, Bacteroidota, Firmicutes, and Actinobacteriota were the dominant phyla in the oral cavity. 16 S rRNA sequencing analysis of fecal samples showed that: (1) Bacteroidota was the most abundant in Japalura sensu lato, which was different from the bacterial community of insectivorous animals; (2) Bacteroidota, Firmicutes, Actinobacteriota, Fusobacteriota, and Cyanobacteria were the most abundant phylum in Japalura sensu lato. (3) Proteobacteria was the dominant phylum in Japalura sensu lato and other domestic insectivorous lizards (Shinisaurus crocodilurus, Phrynocephalus vlangalii, and Takydromus septentrionalis); (4) Comparing with the bacterial community of Shinisaurus crocodilurus, Phrynocephalus vlangalii, Takydromus septentrionalis, Liolaemus parvus, L. ruibali, and Phymaturus williamsi, Desulfobacterota was uniquely present in the gut of Japalura sensu lato. 16 S rRNA sequencing of oral samples showed that Chloroflexi and Deinococcota phyla were enriched in the oral cavity, which may have a significant influence on living in extreme environments. Conclusions Thus, based on 16 S rRNA sequencing analysis of the community composition of the gut and oral microbiomes, this study firstly represents a foundation for understanding the gut and oral microbial ecology of Japalura sensu lato, and constitutes a detail account of the diversity of the microbiota inhabiting the gut and oral cavity of Japalura sensu lato. Further researches will continue to reveal how gut and oral microbial communities may be impacting the ecology and evolution of lizards.

Abstract
Budgerigar fledgling disease virus (BFDV) is the causative polyomavirus of budgerigar fledgling disease, an important avian immunosuppressive disease in budgerigars (Melopsittacus undulatus). In the current study, we explored the etiological role and molecular characteristics of BFDV. We identified a novel BFDV strain, designated as SC-YB19, belonging to a unique cluster with three other domestic strains (WF-GM01, SD18, and APV-P) and closely related to Polish isolates based on complete sequences. Sequence analysis showed that SC-YB19 had an 18-nucleotide (nt) deletion in the enhancer region, corresponding to the sequence position 164–181 nt, which differed significantly from all other BFDV strains. Based on sequence alignment, three unique nucleotide substitutions were found in VP4 (position 821), VP1 (position 2,383), and T-antigen (position 3,517) of SC-YB19, compared with SD18, WF-GM01, QDJM01, HBYM02, APV7, and BFDV1. Phylogenetic analyses based on complete sequences suggested that SC-YB19, along with the domestic WF-GM01, SD18, and APV-P strains, formed a single branch and were closely related to Polish, Japanese, and American isolates. These results demonstrate that BFDV genotype variations are co-circulating in China, thus providing important insight into BFDV evolution.

Primary cutaneous anaplastic large cell lymphoma (PC-ALCL) is the second most type of cutaneous lymphoma of T cell origin. Although PC-ALCL is considered clinically indolent with an excellent overall survival rate, very few studies have examined the epidemiology and survival of this disease in significant depth. Here we have used the National Cancer Institute’s Surveillance, Epidemiology, and End Results (SEER) database to identify the cases of PC-ALCL with immunohistologic or molecular confirmation and analyzed disease-specific survival across various epidemiological factors.
Methods/Case Report
We identified patients with PC-ALCL from the SEER database from 1975 - 2017. Cases with only histological and immunohistochemical or molecular evidence of diagnosis were included in the study. Age, sex, and race-standardized incidence rates (IR) were calculated. Survival was assessed using Kaplan-Meier curves and Cox proportional hazards models.
Results (if a Case Study enter NA)
93 individuals were identified with a diagnosis of PC-ALCL. Increased age correlated significantly with the total number of cases within age groups, suggesting an associated risk. Males were significantly overrepresented in the disease population at 62%. The racial distribution of patients with PC-ALCL did not significantly differ from the racial distribution in the US. Kaplan-Meier DSS analysis was performed to assess possible influence of race, sex, age, or primary site location on the prognosis in patients with PC-ALCL. Age appears to be one of the greatest factors influencing survival, and while this trended strongly, it was not a statistically significant observation. Although males were disproportionately represented among PC-ALCL patients, sex did not affect survival. Similarly, the patient’s race had no significant effect on the length of survival. The location of the primary tumor trends towards affecting survival, and while this is quantitatively the most impressive observation, it does not reach the threshold of statistical significance.
Conclusion
We performed a comprehensive review of the clinical and epidemiological features present in PC-ALCL. We found age to be the most significant factor in the risk of development of PC-ALCL, and while our study lacks the statistical power to demonstrate it, age may also be the most significant factor in survival.

Abstract
Abstract
Introduction/Objective
Epithelioid sarcoma (ES) is a rare, malignant mesenchymal neoplasm that has a known tendency for local recurrence, regional lymph node involvement, and distant metastases. Two histologic variants have been recognized: classic ES also known as the distal type, and proximal-type ES (PES). The classic ES is common in young adults. It occurs more frequently in the distal upper extremities followed by the distal lower limbs and has a male prevalence of 2:1. Conversely, PES commonly involves deep tissues in the pelvic region, including the genital area. It tends to occur in older patients and follows a more aggressive clinical course. In the female genital tract, PES occurs most frequently in the vulva. The incidence of primary sarcoma of the vulva accounts for 1.5-5% of all malignant tumors, making PES a very rare incidence.
Methods/Case Report
Here we report a 60-year-old female diagnosed with vulvar epithelioid sarcoma treated with a right radical vulvectomy and bilateral inguinal lymph node dissection in 2008. In 2017, further surgery and adjuvant radiation were given for local recurrence. In 2020, the patient developed left hip pain and was found to have an expansile lytic lesion in the left proximal femur. Extensive resection was performed. Grossly the vulvar lesion was nodular with diffuse hemorrhage, degeneration, and necrosis. Microscopically, the tumor cells had large vesicular nuclei, prominent nucleoli, and abundant eosinophilic cytoplasm. Histologically, the morphology of the tumor cells are similar for the primary vulvar specimen and the bone metastases. Immunohistochemically, the tumor cells are positive for vimentin, GATA, FLI-1, SMA, SMHC, partially positive for CAM5.2, AE1/AE3, CD31, and CD163. Immunohistochemistry was negative for CDX2, CD56, S-100, TTF-1, CK5/6, CK20, P40, mammoglobin, MOC31, ER, CK7, CK903, HMB45, PAX8. A Ki-67 proliferative index was around 30-40%. NGS molecular testing detected a SMARCB1 mutation with loss of exons 1-3 and exons 7-9 supporting the diagnosis of epithelioid sarcoma.
Results (if a Case Study enter NA)
NA
Conclusion
In summary, we report a case of PES of the vulva in a 60 year old female. Grossly, the lesion was nodular with histology showing large vesicular nuclei, prominent nucleoli, and abundant eosinophilic cytoplasm. It showed loss of INI1/SMARCB1 nuclear expression. The patient is receiving further adjuvant treatment and shows no new metastases.

Abstract
Prevention of bacterial infection and reduction of hemorrhage, the primary challenges posed by trauma before hospitalization, are essential steps in prolonging the patient's life until they have been transported to a trauma center. Extracellular matrix (ECM) hydrogel is a promising biocompatible material for accelerating wound closure. However, due to the lack of antibacterial properties, this hydrogel is difficult to be applied to acute contaminated wounds. This study formulates an injectable dermal extracellular matrix hydrogel (porcine acellular dermal matrix (ADM)) as a scaffold for skin defect repair. The hydrogel combines vancomycin, an antimicrobial agent for inducing hemostasis, expediting antimicrobial activity, and promoting tissue repair. The hydrogel possesses a porous structure beneficial for the adsorption of vancomycin. The antimicrobial agent can be timely released from the hydrogel within an hour, which is less than the time taken by bacteria to infest an injury, with a cumulative release rate of approximately 80%, and thus enables a relatively fast bactericidal effect. The cytotoxicity investigation demonstrates the biocompatibility of the ADM hydrogel. Dynamic coagulation experiments reveal accelerated blood coagulation by the hydrogel. In vivo antibacterial and hemostatic experiments on a rat model indicate the healing of infected tissue and effective control of hemorrhaging by the hydrogel. Therefore, the vancomycin-loaded ADM hydrogel will be a viable biomaterial for controlling hemorrhage and preventing bacterial infections in trauma patients.

Abstract
Many people experience high burden by the outbreak of the coronavirus disease (COVID-19) and its consequences for health and everyday life. The present cross-national study investigated potential factors that can reduce the burden by COVID-19 in China and Germany. Cross-sectional and longitudinal (China: N = 474, baseline, BL: 2015, follow-up, FU: 2020; Germany: N = 359, BL: 2019, FU: 2020) data on physical activity (e.g., jogging) (BL/FU), positive mental health (PMH) (BL/FU), and burden by COVID-19 (FU) were collected via online surveys. In both countries, physical activity was positively associated with PMH, and both variables were negatively related to burden by COVID-19. Furthermore, PMH mediated the link between physical activity and burden. The mediation model was significant when physical activity and PMH were assessed at the BL, while burden was measured at the FU; and it was also significant when all variables were assessed at the FU. The present findings reveal that physical activity in combination with PMH can reduce the experience of burden by COVID-19. Conscious fostering of physical activity and PMH is supported as an effective strategy to reduce the negative impact of the pandemic outbreak on mental and physical health. Additional benefits such as increased adherence to governmental measures around COVID-19 are discussed.

Abstract
We investigated changes in concentrations of ADP (adiponectin), LEP (leptin), BHBA (beta-hydroxybutyric acid), NEFA (non-esterified fatty acid), Glucose (Glu) and INS (insulin) in serum of healthy perinatal dairy cows and cows with ketosis. Twenty-one healthy cows and seventeen cows with ketosis from a herd of a total 60 Holstein cows (near dry period i.e. 56 days antepartum) were selected. Blood was collected through the tail vein every 7 days, from 56 day antepartum to 56 day postpartum. Serum ADP, LEP, BHBA, NEFA, Glu, and INS concentrations were determined, and ketosis was diagnosed through serum BHBA (≥1.2 mmol/L). We showed the concentration of serum adipokines and energy balancing indices were stable during antepar- tum period. However, ADP concentration increased while LEP decreased, and there were a significant increase in cows with ketosis compared to that of in healthy cows. Serum BHBA and NEFA concentrations increased significantly at first, and then gradually decreased in both healthy cows and cows with ketosis. However, cows with ketosis showed higher concentrations of BHBA and NEFA which restored later. The serum concentration of Glu in both healthy dairy cows and cows with ketosis showed a decreasing trend. INS concentration in healthy cows was decreased while it was increased in cows with ketosis. The results reflect the extent of hypo- glycemia and lipid mobilization postpartum, suggest IR exists in cows with ketosis while serum ADP and LEP might play roles in the development of ketosis.

Abstract
Nonfullerene acceptors are being investigated for use in polymer solar cells (PSCs), with their advantages of extending the absorption range, reducing the energy loss and therefore enhancing the power conversion efficiency (PCE). However, to further boost the PCE, mobilities of these nonfullerene acceptors should be improved. For nonfullerene acceptors, the π-π stacking distance between cofacially stacked molecules significantly affects their mobility. Here, we demonstrate a strategy to increase the mobility of heteroheptacene-based nonfullerene acceptors by reducing their π-π stacking distances via control over the bulkiness of lateral side chains. Incorporation of 2-butyloctyl substituents into the nonfullerene acceptor (M36) leads to an increased mobility with a reduced π-π stacking distance of 3.45 Å. Consequently, M36 affords an enhanced PCE of 16%, which is the highest among all acceptor-donor-acceptor-type nonfullerene acceptors to date. This strategy of control over the bulkiness of side chains on nonfullerene acceptors should aid the development of more efficient PSCs.

Abstract
Objective: To explore the effects of two dimensional gray-scale blood flow imaging (hereinafter referred to as " B-flow" ) combined with color Doppler flow imaging (CDFI) in guiding arterial puncture and catheterization through wounds in patients with large burns. Methods: Sixty-seven patients with large burns who met the inclusion criteria and hospitalized in the First Hospital of Jilin University from January 2017 to January 2019 were enrolled in the prospectively randomized control study. According to the random number table, CDFI alone group was allocated with 35 patients (23 males and 12 females) and B-flow+ CDFI group with 32 patients (22 males and 10 females), aged 19-60 and 18-58 years, respectively. According to the progress of the disease, arterial puncture and catheterization were performed in the right time. During the operation, CDFI was used alone for guidance in patients of CDFI alone group, while B-flow and CDFI were used together for guidance in patients of B-flow+ CDIF group. Based on the first time of catheterization, the catheterization location, one-time catheterization success rate, post-back stitching re-catheterization success rate, catheterization failure rate, catheterization duration, and incidences of wound sepsis, catheter-related bloodstream infection, and arterial thrombosis within post catheterization day (PCD) 3 of patients in the two groups were recorded. Data were statistically analyzed with the independent-sample t test, chi-square test or Fisher's exact probability test. Results: (1) All the patients underwent catheterization through wounds, and there was no statistically significant difference in catheterization location of patients between the two groups (χ(2)=0.574, P>0.05). The one-time catheterization success rate of patients in B-flow+ CDFI group was 81.25% (26/32), which was obviously higher than 51.43% (18/35) in CDFI alone group (χ(2)=6.594, P<0.05). The catheterization failure rate of patients in B-flow+ CDFI group was 3.12% (1/32), which was obviously lower than 20.00% (7/35) in CDFI alone group (P<0.05). The post-back stitching re-catheterization success rate of patients was similar between the two groups (χ(2)=1.029, P>0.05). (3) The catheterization duration of patients was (15.7±1.1) min in B-flow+ CDFI group, which was obviously shorter than (17.1±2.2) min in CDFI alone group (t=11.316, P<0.01). (4) Within PCD 3, the incidences of wound sepsis and catheter-related bloodstream infection of patients in CDFI alone group were 2.86% (1/35) and 0, close to 0 and 3.12% (1/32) in B-flow+ CDFI group (P>0.05); the incidence of arterial thrombosis of patients in B-flow+ CDFI group was 0, which was obviously lower than 20.00% (7/35) in CDFI alone group (P<0.05). Conclusions: Compared with CDFI alone, B-flow combined with CDFI can improve the success rate of arterial puncture and catheterization through wounds in large area burn patients, shorten the catheterization duration, and effectively reduce the incidence of arterial thrombosis after catheterization, with a good clinical application value.

Abstract
OA is now well accepted as a low-grade inflammatory disease affecting the whole joint. In addition to mechanical loading, inflammation (particularly synovitis), contributes significantly to OA. Synovial macrophages act as immune cells and are of critical importance in the symptomology and structural progression of OA. Activated macrophages are regulated by mTOR, NF-κB, JNK, PI3K/Akt and other signaling pathways, and are polarized into either M1 or M2 subtypes in OA synovial tissues, synovial fluid, and peripheral blood. The activation state and the M1/M2 ratio is highly associated with OA severity. Aside from autocrine interactions, paracrine interactions between macrophages and chondrocytes play a vital role in the initiation and development of OA by secreting inflammatory cytokines, growth factors, matrix metalloproteinases (MMPs) and tissue inhibitor of metalloproteinases (TIMPs), which lead to subsequent cartilage degradation and destruction. Treatments targeting synovial macrophages relieve pain, and protect from synovitis, cartilage damage, and osteophyte formation during OA development. Macrophage reprogramming of transformation from the M1 to M2 subtype, more than a decrease in the quantity of activated macrophages, appears to be an effective treatment option for OA. This review provides a broad understanding of the contributions of polarized macrophages to joint health and disease. Multifunctional agents with immunomodulatory effects on macrophage reprogramming can skew the inflammatory microenvironment towards a pro-chondrogenic atmosphere, and are thus, potential therapeutic options for the treatment of OA and other immune diseases.

Abstract
AIMS Poly-γ-glutamic acid (γ-PGA) is an excellent water-soluble biosynthesis material. To confirm the rate-limiting steps of γ-PGA biosynthesis pathway, we introduced a heterologous Bacillus strain pathway and employed an enzyme-modulated dismemberment strategy in Escherichia coli. METHODS AND RESULTS In this study, we heterologously introduced the γ-PGA biosynthesis pathway of two laboratory-preserved strains-Bacillus amyloliquefaciens FZB42 and Bacillus subtilis 168 into E. coli, and compared their γ-PGA production levels. Next, by changing the plasmid copy numbers and supplying sodium glutamate, we explored the effects of gene expression levels and concentrations of the substrate l-glutamic acid on γ-PGA production. We finally employed a two-plasmid induction system using an enzyme-modulated dismemberment of pgsBCAE operon to confirm the rate-limiting genes of the γ-PGA biosynthesis pathway. CONCLUSION Through heterologously over-expressing the genes of the γ-PGA biosynthesis pathway and exploring gene expression levels, we produced 0·77 g l-1 γ-PGA in strain RSF-EBCAE(BS). We also confirmed that the rate-limiting genes of the γ-PGA biosynthesis pathway were pgsB and pgsC. SIGNIFICANCE AND IMPACT OF THE STUDY This work is beneficial to increase γ-PGA production and study the mechanism of γ-PGA biosynthesis enzymes.

Abstract
In order to achieve efficient bioconversion of biomass-derived sugars, acid hydrolysate of sweet sorghum juice (SSJAH) containing abundant fermentable sugars was used for coenzyme Q10 (CoQ10) fermentation by Rhodobacter sphaeroides CQ-09-1. The synthesis of CoQ10 was facilitated when the initial concentration of total sugar was 80.00 g L-1. And the highest CoQ10 titer was obtained when the pH and temperature were maintained at 7.00 and 30.00 °C, respectively. Moreover, corn steep powder (CSP) was proved to be an efficient nitrogen & salt supplement to SSJAH. Under the optimized conditions, the titer of CoQ10 reached 141.95 mg L-1 in a fed-batch fermentation. The CoQ10 titer reported was about two times higher than that obtained in the previous study using wild strains. This process introduces a potential way to produce CoQ10 using the concept of biorefinery, while making full use of sweet sorghum juice (SSJ).

Abstract
Effective cultivation methods, total cost, and biomass preservation are key factors that have a significant impact on the commercialisation and effectiveness of probiotics, such as Lactobacillus. Sugar polymers, milk and whey proteins have been suggested as good additives for industrial preparations. Alternative compounds, such as phytophenols, are a more attractive option, given their potential benefits to human health. The overall goal of this study was to determine if the addition of blueberry phytophenols improves the survival of Lactobacillus johnsonii N6.2 during the freeze-drying process. The addition of blueberry aqueous extract (BAE) stimulated the growth of L. johnsonii under aerobic conditions and improved the stationary phase survival of the bacteria. Furthermore, the addition of BAE to the culture media improved the endurance of L. johnsonii N6.2 to freeze-drying stress, as well as to storage at 4 °C for up to 21 weeks. Moreover, blueberry extract performed more effectively as a lyophilising additive compared to skim milk and microencapsulation with whey protein/sodium alginate. In sum, this study demonstrates that BAE is an effective additive to increase the growth and survival of L. johnsonii N6.2 when added to the culture medium and/or used as a lyophilising preservative. Moreover, BAE or other polyphenols sources might likely enhance growth and increase survival of more probiotic lactic acid bacterial strains.

Abstract
OBJECTIVE Hydrazone compounds and their derivatives are a kind of special Schiff bases. The multiple hydrazone compounds and their derivatives have a variety of biological activities. This study aims to report the synthesis of diverse hydrazone derivatives and to explore the potent antitumor activities. MATERIALS AND METHODS A series of aromatic heterocyclic sulfonyl hydrazones W1-W15 synthesized from hydrazine or acylhydrazine and aldehydes or ketones were estimated for their in vitro antitumor activities against human cancers. Through the spectral (FT-IR, 1H-NMR, MS) methods, the structure of the compounds was determined. Using MTT (3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide) method, the effects of different concentrations of compounds on growth inhibition and viability of HepG-2 cells were detected. RESULTS Compound W9 exhibited anti-proliferation activity with IC50 values of 63.91 μmol/L in HepG-2 cell line. In addition, mechanism studies indicated that compound W9 could distinctly prohibit the propagation of HepG-2 cells by arresting the cell cycle at G2/M and inducing apoptosis. Furthermore, we investigated the effectiveness of drug combination treatment with W9 and cis-platinum (cis-DDP) or 5-fluorouracil (5-FU) on HepG-2 cell line. CONCLUSIONS Our results indicated that W9 with synergic treatment of 5-FU or cis-DDP shows better inhibitory cell growth. The combination of the two drugs blocks HepG-2 cells in the G2/M phase. The inhibitory effect of W9 on cell apoptosis was decreased with the increase of drug concentration.

Abstract
Multifunctional nano-biomaterials with the integration of diagnostic and therapeutic functions have shown great promise in improving the efficacy of cancer therapy. Herein, a new nanoplatform based on functionalized Cu3BiS3 nanoparticles (NPs) is fabricated for tumour-targeted combination phototherapy. The as-synthesized hydrophobic Cu3BiS3 NPs are modified with DSPE-PEG/DSPE-PEG-NH2, followed by the conjugation of the photosensitizer chlorin e6 (Ce6) and the target ligand folic acid (FA). The introduced Ce6 can further form a chelate complex with Gd3+. The rationally designed Cu3BiS3-PEG-(Ce6-Gd3+)-FA NPs, which have high physiological stability and good biocompatibility, can specifically target FA-receptor over-expressed tumour cells. The Cu3BiS3-PEG-(Ce6-Gd3+)-FA NPs exhibit effective dual-modal CT and MR imaging in the xenografted HeLa tumours. Importantly, excellent in vivo anti-tumour effects have been achieved by synergistic photothermal/photodynamic therapy using the multifunctional NPs. We expect that this versatile nanoplatform will play a role in exploring precise cancer diagnosis and therapy.

Abstract
Macrophages are distributed throughout the body and are crucial for the restoration of damaged tissues. However, their characteristics in the cornea and roles in the repair of corneal injures are unclear. Here we show that corneal macrophages can be classified as CCR2- macrophages, which already exist in the cornea at embryonic day 12.5 (E12.5) and are similar to yolk sac-derived macrophages, microglia, in phenotype and gene expression, and CCR2+ macrophages, which do not appear in the cornea until E17.5. At a steady state, CCR2- corneal macrophages have local proliferation capacity and are rarely affected by monocytes; however, following corneal epithelial abrasion, most CCR2- corneal macrophages are replaced by monocytes. In contrast, CCR2+ macrophages are repopulated by monocytes under both a steady-state condition and following corneal wounding. Depletion of CCR2+ macrophages decreases corneal inflammation after epithelial abrasion, whereas depletion of CCR2- macrophages increases inflammation of the injured cornea. Loss of either cell type results in a delay in corneal healing. These data indicate that there are two unique macrophage populations present in the cornea, both of which participate in corneal wound healing by balancing the inflammatory response.

Abstract
OBJECTIVE Articular chondrocyte activation, involving aberrant proliferation and prehypertrophic differentiation, is essential for osteoarthritis (OA) initiation and progression. Disruption of mechanistic target of rapamycin complex 1 (mTORC1) promotes chondrocyte autophagy and survival, and decreases the severity of experimental OA. However, the role of cartilage mTORC1 activation in OA initiation is unknown. In this study, we elucidated the specific role of mTORC1 activation in OA initiation, and identify the underlying mechanisms. METHOD Expression of mTORC1 in articular cartilage of OA patients and OA mice was assessed by immunostaining. Cartilage-specific tuberous sclerosis complex 1 (Tsc1, mTORC1 upstream inhibitor) knockout (TSC1CKO) and inducible Tsc1 KO (TSC1CKOER) mice were generated. The functional effects of mTORC1 in OA initiation and development on its downstream targets were examined by immunostaining, western blotting and qPCR. RESULTS Articular chondrocyte mTORC1 was activated in early-stage OA and in aged mice. TSC1CKO mice exhibited spontaneous OA, and TSC1CKOER mice (from 2 months) exhibited accelerated age-related and DMM-induced OA phenotypes, with aberrant chondrocyte proliferation and hypertrophic differentiation. This was associated with hyperactivation of mTORC1 and dramatic downregulation of FGFR3 and PPR, two receptors critical for preventing chondrocyte proliferation and differentiation. Rapamycin treatment reversed these phenotypes in KO mice. Furthermore, in vitro rescue experiments demonstrated that p73 and ERK1/2 may mediate the negative regulation of FGFR3 and PPR by mTORC1. CONCLUSION mTORC1 activation stimulates articular chondrocyte proliferation and differentiation to initiate OA, in part by downregulating FGFR3 and PPR.

Abstract
The present study examined Chinese students’ personal value orientations according to the Schwartz value theory in comparison with students from Germany and Russia. The theory postulates 10 value orientations grouped into four higher-order factors: conservation versus openness to change and self-transcendence versus self-enhancement. Schwartz’ value orientations have been extensively investigated in Europe but less in East Asian countries such as China. We hypothesized that Chinese students would score higher on conservation and self-enhancement than German and Russian students, but lower on self-transcendence. Regarding openness to change, a null hypothesis was formulated. Students from China ( n = 9,601), Germany ( n = 1,118), and Russia ( n = 3,890) completed the Portrait Values Questionnaire (PVQ-21). To ensure methodological preconditions for cross-cultural comparison, measurement invariance of the PVQ-21 was tested. In a first step, confirmatory Factor Analysis (CFA) was conducted separately for each country. Due to the high correlation between the 10 values, the four higher-order dimensions were studied separately. Configural, metric, and scalar invariance models were tested using multigroup CFA. Full metric and partial scalar invariance models held for all higher-order factors. Thereafter, latent means of values were compared across samples. As a result, Chinese students scored highest on the four higher-order dimensions when compared with Russian and German samples, thus the hypotheses were only partly confirmed. Results of this study could reflect the value conflicts emerging from various cultural influences in contemporary China: Young people are confronted with daily negotiation between Confucian tradition and the rapid economic development.

Abstract
This study investigated the prevalence, risk factors and association of occlusive wear with non-carious cervical lesions (NCCLs) in the general Chinese population. A total of 1320 subjects were recruited, and multistage and random sampling methods of survey spots were performed. All age groups comprised similar numbers of participants and equal numbers of males and females. Each subject completed a structured interview, and all teeth of each subject were examined by a practitioner to determine NCCLs and occlusive wear. Binary logistic regression was conducted by analysing the association of risk factors with the occurrence of NCCLs. Bivariate correlation analysis was performed by determining the association of NCCLs dimension or depth with the range of occlusive wear facets. Clinical assessment showed that the overall prevalence of subjects diagnosed with NCCLs was 63%. The proportion of subjects or teeth with NCCLs significantly increased with age. Pre-molars were the most commonly affected teeth. Single variables and interactive effects of variables associated with the occurrence of NCCLs include the following: age group, intensity of toothbrushing, frequency of fresh fruit consumption and interactive effect between intensity of toothbrushing and frequency of fresh fruit consumption. A weak positive correlation of the grading index was found between NCCLs dimension, size or depth and range of occlusive wear facets. This study reported the higher prevalence of NCCLs in the general Chinese population. Implementation of a combined strategy to reduce risk factors of NCCLs could be more effective than individual techniques; meanwhile, the occurrence of NCCL could be related to the wear degree of occlusive defects in the population studied.

Abstract
Inverted polymer solar cells (PSCs) with high open-circuit voltages of 1.00-1.06 V are fabricated by using an indenofluorene-containing copolymer (PIFTBT8) as an electron donor material and [6,6]-phenyl-C71-butyric acid methyl ester (PC71BM) as an electron acceptor material. To improve the photovoltaic performance, interface control of various low-temperature processed ZnO films as cathode buffer layers is systematically investigated for effective electron transportation, while transition metal oxides including MoO3, WO3, NiO, and Cu2O are employed as anode buffer layers for hole-extraction. Incorporation of optimized semiconducting metal oxide interlayers can minimize interfacial power losses, which thus affords large open-circuit voltages (Voc), increased short-circuit current densities (Jsc), and fill factors (FF), eventually contributing to higher power conversion efficiencies (PCEs) as well as better device stability. Due to the improved interfacial contacts and fine-matching energy levels, inverted PSCs with a device configuration of ITO/ZnO/PIFTBT8:PC71BM/MoO3/Ag exhibit a high PCE of 5.05% with a large Voc of 1.04 V, a Jsc of 9.74 mA cm(-2), and an FF of 50.1%. For the single junction inverted PSCs with efficiencies over 5.0%, 1.04 V is the largest Voc ever achieved. By controlling the processing conditions of the active layer, the Voc can further be improved to 1.05 and 1.06 V, with PCEs of 4.70% and 4.18%, respectively. More importantly, the inverted PSCs are ascertained to maintain a PCE of 4.55% (>90% of its initial efficiency) and a Voc of 1.05 V over 180 days, demonstrating good long-term stability, which is much better than that of the conventional devices. The results suggest that the interface engineering of metal oxide interlayers is an important strategy to develop PSCs with good performance.
