Abstract
Background Resilience is vital for improving mental health and well-being during adolescence, which is an important yet vulnerable period. Previous research has indicated that physical activity enhances individual resilience. However, limited studies have examined underlying psychological mechanisms between them. The current study aimed to investigate the effect of physical activity on adolescent resilience via self-efficacy and basic psychological needs. Methods A cross-sectional survey was conducted with 1,732 high school students aged 16 to 20 years old (mean age: 16.51 ± 0.77 years), with nearly equal number of boys (47.63%) and girls (52.37%). They each completed the Physical Exercise Questionnaire, Basic Psychological Needs in Exercise Scale, General Self-Efficacy Scale, and Resilience Scale, respectively. A serial indirect model was constructed to examine how physical activity influences resilience. Results Structural equation model analysis revealed that physical activity significantly and directly predicted resilience. When self-efficacy and basic psychological needs were included in the model, both direct and indirect effects were observed. Specifically, the positive relationship between physical activity and resilience was partially mediated by self-efficacy and basic psychological needs. In addition, basic psychological needs and self-efficacy were found to serially mediate the direct relathonship between physical activity and resilience. Conclusions The present study provides novel theoretical insights into sports psychology by establishing a link between basic psychological needs and self-efficacy. The findings have implications for school administrators and physical education instructors in designing targeted interventions to promote adolescent resilience. These interventions may involve creating supportive environment conductive to fulfilling students' basic psychological needs, implementing strategies to enhance self-efficacy beliefs, and providing opportunities for skill development and mastery experiences in sports and physical activities.

Abstract
Introduction: Chronic stress exposure is the main environmental factor leading to cognitive impairment, but the detailed molecular mechanism is still unclear. Adenosine Deaminase acting on double-stranded RNA1(ADAR1) is involved in the occurrence of chronic stress-induced cognitive impairment. In addition, dopamine and Adenosine 3'5'-monophosphate-regulated phospho-protein (DARPP-32) gene variation affects cognitive function. Therefore, we hypothesized that ADAR1 plays a key role in chronic stress-induced cognitive impairment by acting on DARPP-32. Methods: In this study, postnatal 21-day-old male BALB/c mice were exposed to chronic unpredictable stressors. After that, the mice were treated with ADAR1 inducer/inhibitor. The cognitive ability and cerebral DARPP-32 protein expression of BALB/c mice were evaluated. In order to explore the link between ADAR1 and DARPP-32, the effects of ADAR1 high/low expression on DARPP-32 protein expression in vitro were detected. Results: ADAR1 inducer alleviates cognitive impairment and recovers decreased DARPP-32 protein expression of the hippocampus and prefrontal cortex in BALB/c mice with chronic unpredictable stress exposure. In vivo and in vitro studies confirm the results predicted by bio-informatics; that is, ADAR1 affects DARPP-32 expression via miR-874-3p. Discussion: The results in this study demonstrate that ADAR1 affects the expression of DARPP-32 via miR-874-3p, which is involved in the molecular mechanism of pathogenesis in chronic unpredictable stress-induced cognitive impairment. The new findings of this study provide a new therapeutic strategy for the prevention and treatment of stress cognitive impairment from epigenetics.

Abstract
MOTIVATION The k-mer frequency in whole genome sequences provides researchers with an insightful perspective on genomic complexity, comparative genomics, metagenomics and phylogeny. The current k-mer counting tools are typically slow, and they require large memory and hard disk for assembled genome analysis. RESULTS We propose a novel and ultra-fast k-mer counting algorithm, KCOSS, to fulfill k-mer counting mainly for assembled genomes with segmented Bloom filter, lock-free queue, lock-free thread pool and cuckoo hash table. We optimize running time and memory consumption by recycling memory blocks, merging multiple consecutive first-occurrence k-mers into C-read, and writing a set of C-reads to disk asynchronously. KCOSS was comparatively tested with Jellyfish2, CHTKC and KMC3 on seven assembled genomes and three sequencing datasets in running time, memory consumption, and hard disk occupation. The experimental results show that KCOSS counts k-mer with less memory and disk while having a shorter running time on assembled genomes. KCOSS can be used to calculate the k-mer frequency not only for assembled genomes but also for sequencing data. AVAILABILITYAND IMPLEMENTATION The KCOSS software is implemented in C++. It is freely available on GitHub: https://github.com/kcoss-2021/KCOSS. SUPPLEMENTARY INFORMATION Supplementary data are available at Bioinformatics online.

Abstract
Type 2 diabetes (T2D) patients with SARS-CoV-2 infection hospitalized develop an acute cardiovascular syndrome. It is urgent to elucidate underlying mechanisms associated with the acute cardiac injury in T2D hearts. We performed bioinformatic analysis on the expression profiles of public datasets to identify the pathogenic and prognostic genes in T2D hearts. Cardiac RNA-sequencing datasets from db/db or BKS mice (GSE161931) were updated to NCBI-Gene Expression Omnibus (NCBI-GEO), and used for the transcriptomics analyses with public datasets from NCBI-GEO of autopsy heart specimens with COVID-19 (5/6 with T2D, GSE150316), or dead healthy persons (GSE133054). Differentially expressed genes (DEGs) and overlapping homologous DEGs among the three datasets were identified using DESeq2. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes analyses were conducted for event enrichment through clusterProfile. The protein-protein interaction (PPI) network of DEGs was established and visualized by Cytoscape. The transcriptions and functions of crucial genes were further validated in db/db hearts. In total, 542 up-regulated and 485 down-regulated DEGs in mice, and 811 up-regulated and 1399 down-regulated DEGs in human were identified, respectively. There were 74 overlapping homologous DEGs among all datasets. Mitochondria inner membrane and serine-type endopeptidase activity were further identified as the top-10 GO events for overlapping DEGs. Cardiac CAPNS1 (calpain small subunit 1) was the unique crucial gene shared by both enriched events. Its transcriptional level significantly increased in T2D mice, but surprisingly decreased in T2D patients with SARS-CoV-2 infection. PPI network was constructed with 30 interactions in overlapping DEGs, including CAPNS1. The substrates Junctophilin2 (Jp2), Tnni3, and Mybpc3 in cardiac calpain/CAPNS1 pathway showed less transcriptional change, although Capns1 increased in transcription in db/db mice. Instead, cytoplasmic JP2 significantly reduced and its hydrolyzed product JP2NT exhibited nuclear translocation in myocardium. This study suggests CAPNS1 is a crucial gene in T2D hearts. Its transcriptional upregulation leads to calpain/CAPNS1-associated JP2 hydrolysis and JP2NT nuclear translocation. Therefore, attenuated cardiac CAPNS1 transcription in T2D patients with SARS-CoV-2 infection highlights a novel target in adverse prognostics and comprehensive therapy. CAPNS1 can also be explored for the molecular signaling involving the onset, progression and prognostic in T2D patients with SARS-CoV-2 infection.

Abstract
Multiobjective multitasking optimization (MTO), which is an emerging research topic in the field of evolutionary computation, was recently proposed. MTO aims to solve related multiobjective optimization problems at the same time via evolutionary algorithms. The key to MTO is the knowledge transfer based on sharing solutions across tasks. Notably, positive knowledge transfer has been shown to facilitate superior performance characteristics. However, how to find more valuable transferred solutions for the positive transfer has been scarcely explored. Keeping this in mind, we propose a new algorithm to solve MTO problems. In this article, if a transferred solution is nondominated in its target task, the transfer is positive transfer. Furthermore, neighbors of this positive-transfer solution will be selected as the transferred solutions in the next generation, since they are more likely to achieve the positive transfer. Numerical studies have been conducted on benchmark problems of MTO to verify the effectiveness of the proposed approach. Experimental results indicate that our proposed framework achieves competitive results compared with the state-of-the-art MTO frameworks.

Abstract
OBJECTIVE To investigate the role(s) of hyaluronan synthase 2 (HAS2) and hyaluronan in disease progression of endometriosis and epidermal growth factor (EGF)-induced motility changes of endometriotic cells. DESIGN A case-control experimental study and in vitro primary cell culture study. SETTING University hospital-affiliated research centers. PATIENTS A total of 21 women with stage I/II endometriosis, 33 women with stage III/IV endometriosis with endometrioma, and 32 women without endometriosis were included in our study. INTERVENTIONS Serum, eutopic endometrial tissues, and/or ectopic endometriotic tissues were collected. Primary eutopic endometrial stromal cells (EuESCs) and ectopic ovarian endometriotic stromal cells (OvESCs) were isolated and cultured from women with ovarian endometrioma, and then treated with or without EGF. MAIN OUTCOME MEASURES The concentrations of EGF and hyaluronan in serum were analyzed by enzyme-linked immunosorbent assay. The expressions and localizations of EGF receptor (EGFR), phosphorylated-(p)EGFR, HAS2, and hyaluronan receptor CD44 in tissues were examined by immunohistochemistry. The mRNA and protein levels of HAS2 in EuESCs and OvESCs were examined by reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and western blot, respectively, and the concentrations of hyaluronan in conditioned medium were examined by enzyme-linked immunosorbent assay (ELISA). Cell motility was evaluated by transwell migration/invasion assays. RESULTS Serum EGF and hyaluronan concentrations were higher in women with stage III/IV endometriosis than in women with stage I/II or without endometriosis. EGFR, pEGFR, HAS2, and CD44 were immunolocalized in eutopic endometrium and ectopic endometriotic lesions, and the expressions of pEGFR and HAS2 were elevated in ectopic endometriotic lesions compared to eutopic endometrium. Treatment with EGF upregulated HAS2 and hyaluronan expression as well as cell migration and invasion in both EuESCs and OvESCs, and pharmaceutical blocking of EGFR abolished these effects. In addition, knockdown of HAS2 by small interfering RNA attenuated both basal and EGF-induced hyaluronan expression and cell motility changes. Notably, ERK1/2 and AKT signaling pathways were shown to be downstream of EGF in regulating HAS2 and hyaluronan expression as well as cell migration and invasion. CONCLUSION EGF increased the expression of endometriosis-associated hyaluronan and its synthase HAS2, both of which mediated EGF-induced stromal cell migration and invasion in women with endometriosis.

Abstract
S100 calcium-binding protein A6 (S100A6) is up-regulated in many malignancies and overexpression of S100A6 has been identified associated with proliferation, migration and invasion phenotype in several cancer cells. In the present study, we explored whether S100A6 plays a role in the development of endometriosis. Significantly higher levels of mRNA and protein expression of S100A6 were observed in ectopic endometrial tissues compared to eutopic and normal endometrial tissues. Silencing of S100A6 in ectopic endometrial stromal cells (ESCs) significantly inhibited cell viability, migration and invasion. Moreover, knockdown of S100A6 suppressed p38/MAPK activity in ectopic ESCs, which can be partially attenuated by CacyBP/SIP phosphorylation inhibitor. In conclusion, our results suggest that the abnormal expression of S100A6 may contribute to the pathogenesis of endometriosis and the S100A6/CacyBP/p38 signaling may provide as a promising treatment target.

Abstract
OBJECTIVE To investigate the prevalence of hypertension in ocean seamen and major influencing factors, as well as the association between hypertension and serum microRNA21 and microRNA133a. METHODS Health examination and a questionnaire survey were performed for 780 ocean seamen who underwent physical examination in an international travel healthcare center in Fujian, China from January to June, 2014. TaqMan RT-qPCR was used to measure the serum levels of microRNA21 and microRNA133a in seamen with hypertension. RESULTS The prevalence of hypertension differed significantly between the ocean seamen with different ages, education levels, marital status, body mass index (BMI) values, drinking frequencies, and numbers of sailing years (P<0.05). The prevalence rate of hypertension in the ocean seamen increased with the increasing drinking frequency (χ(2)=9.02, P<0.05) , decreased with the increase in degree of education (χ(2)=11.578, P<0.05) , and increased with the increase in the number of sailing years (χ(2)=28.06, P<0.05). The hypertensive ocean seamen had significantly higher expression levels of microRNA21 and MicroRNA133a than the healthy ocean seamen (microRNA21: 7.87±5.46 vs 1.03±0.80, P<0.05; MicroRNA133a: 7.45±1.94 vs 4.52±1.15, P<0.05). The multivariate analysis showed that a high level of microRNA21 (OR=1.61, 95% CI: 1.22~2.11) , a high level of microRNA133a (OR=1.52, 95% CI: 1.24~1.87) , drinking (OR=1.64, 95% CI: 1.08~2.50) , overweight based on BMI (OR=1.18, 95%CI: 1.07~1.30) , and many sailing years (OR=2.89, 95% CI: 1.14~7.30) were risk factors for hypertension. CONCLUSION The prevention and treatment of hypertension in ocean seamen should be enhanced. Excessive drinking should be controlled, and sailing time should be arranged reasonably. The microRNA21 and microRNA133a may be associated with the development and progression of hypertension in ocean seamen.

Abstract
Objective: To analyze the effect of gender on the prognosis of patients with non-small cell lung cancer (NSCLC). Methods: Data of 1 195 patients with NSCLC were analyzed by Chi-square, Kaplan-Meier, log-rank tests and Cox regression models. Results: Women had a longer survival than men (median overall survival 31.64 versus 22.71 months, P<0.01) in the participants of this study. Differences seen in overall survival remained the similar, after stratified by age, pathologic types, clinical stage, sizes, pleural effusion and surgery of the patients, respectively. Data from the multivariate analysis revealed that factors as smoking, clinical stage, metastatic when diagnosis was made and surgery, but not gender, were independent prognostic factors for patients with NSCLC. After adjustment for potential confounders, we found that smoking was a major confounding factor, affecting the relationship between gender and prognosis of NSCLC. Conclusion: Gender did not seem an independent prognostic factor for NSCLC patients while the survival advantages of females might be attributed to the lower prevalence of smoking in this population.

Abstract
Acrolein is a highly electrophilic alpha,beta-unsaturated aldehyde that is present in cigarette smoke. Heme oxygenase-1 (HO-1) is a cytoprotective enzyme activated by various such electrophilic compounds. In this study, the regulatory effects of acrolein upon the expression of HO-1 were investigated in endothelial cells (ECs). We demonstrate that acrolein induces the elevation of HO-1 protein levels, and subsequent enzyme activity, at non-cytotoxic concentrations. An additional alpha,beta-unsaturated aldehyde, cinnamaldehyde, was also found to increase HO-1 expression and have less cytotoxicity than acrolein. Moreover, acrolein-mediated HO-1 induction is abrogated in the presence of actinomycin D and cycloheximide. Nrf2 is a transcription factor involved in the induction of HO-1 through an antioxidant response element (ARE) in the promoter region of the HO-1 gene. We show that acrolein induces Nrf2 translocation and ARE-luciferase reporter activity. Acrolein was also found to induce the production of both superoxide and H2O2 at levels greater than 100 microM. However, with the exception of NAC, no antioxidant generated any effect upon acrolein-dependent HO-1 expression in ECs. Our present findings suggest that reactive oxygen species (ROS) may not be a major modulator for HO-1 induction. Using buthionine sulfoximine to deplete the intracellular GSH levels further enhanced the effects of acrolein. We also found that cellular GSH level was rapidly reduced after both 10 and 100 microM acrolein treatment. However, after 6 h of exposure to ECs, only 10 microM acrolein treatment increases GSH level. In addition, only the JNK inhibitor SP600125 and tyrosine kinase inhibitor genistein had any significant inhibitory impact upon the upregulation of HO-1 by acrolein. Pretreatment with a range of other PI3 kinase inhibitors, including wortmannin and LY294002, showed no effects. Hence, we show in our current experiments that a sublethal concentration of acrolein is in fact a novel HO-1 inducer, and we further identify the principal underlying mechanisms involved in this process.

Abstract
Heme oxygenase-1 (HO-1) is a cytoprotective enzyme activated by various phytochemicals and we examined the ability of Epigallocatechin-3-gallate (EGCG), the major constituent of green tea, to upregulate HO-1 expression in endothelial cells (ECs). We demonstrate that EGCG induces HO-1 expression in a concentration- and time-dependent manner. Furthermore, EGCG-mediated HO-1 induction was abrogated in the presence of actinomycin D and cycloheximide, indicating that this upregulation of HO-1 occurred at the transcriptional level. EGCG also upregulates Nrf2 levels in nuclear extracts and increases ARE-luciferase activity. Furthermore, EGCG is the most potent inducer of HO-1 expression of the different green tea constituents that we analyzed, but had no detectable cytotoxic effects over the 25-100 microM dosage range. The inhibition of intracellular ROS production by N-acetylcysteine (NAC), glutathione (GSH), superoxide dismutase (SOD), catalase and the mitochondrial complex I inhibitor, rotenone, results in a decrease in EGCG-dependent HO-1 expression. In addition, we determined that tyrosine kinase is involved in EGCG induction of HO-1 as this is abrogated by genistein. ECs treated with EGCG exhibit activation of Akt and ERK1/2. In addition, pharmacological inhibitors of phosphatidylinositol 3-kinase and MEK1/2, which are upstream of Akt and ERK1/2, respectively, attenuate EGCG-induced HO-1 expression. On the other hand, pretreatment of these cells with EGCG exerts significant cytoprotective effects against H2O2, suggesting that the induction of HO-1 is an important component in the protection against oxidative stress. Hence, EGCG is a novel phytochemical inducer of HO-1 expression and we further identify the principal underlying mechanisms involved in this process.

Abstract
OBJECTIVE To evaluate the role of matrix metalloproteinases-9 (MMP-9) and tissue inhibitor of metalloproteinases-1 (TIMP-1) in the pathogenesis of chronic obstructive pulmonary disease (COPD). METHODS Five milliliters of peripheral venous blood were extracted form 36 patients with COPD, subdivided into stable group (CS group, n = 12), exacerbation group (CE group, n = 12), and exacerbation group with glucocorticosteroids treatment (CE + G group, n = 12), and 12 normal controls. The peripheral blood mononuclear cells (PBMCs) were isolated and the mRNA expressions of MMP-9 and TIMP-1 therein in each group were measured by RT-PCR quantitative analysis. The MMP-2 and MMP-9 levels in the plasma were studied by gelatin zymography. The relationship between MMP and pulmonary function was evaluated. RESULTS (1) The MMP-9 mRNA expression and MMP-9: TIMP-1 ratios in the samples obtained from patients with COPD were higher in comparison with those from the control group (all P < 0.05). (2) The MMP-9 levels in plasma were higher in the COPD groups than in the control group (P < 0.05). (3) In the COPD groups, the MMP-9 mRNA expression, MMP-9: TIMP-1 ratio, and MMP-9 level in plasma were negatively correlated with FEV(1.0)% of prediction (r = -0.789, P < 0.05; r = -0.53, P < 0.05; and r = -0.652, P < 0.05), and positively correlated with RV/TLC% (r = 0.375, P < 0.05; r = 0.44, P < 0.05; and r = 0.529, P < 0.05). CONCLUSION MMP-9 and the imbalanced ratio of MMP-9: TIMP-1 may not only play a role in the pathogenesis of COPD, but also relate to FEV(1.0)% of prediction and RV/TLC%.

Abstract
OBJECTIVE The aim of this study was to determine whether the activity of topoisomerase I (topo I), the target of the anti-neoplastic drug camptothecin (CPT), is elevated in cervical cancer and whether CPT can radiosensitize cervical tumors. METHODS The topo I activity of 11 normal cervix and 30 cervical carcinoma tumors was assayed by measuring the relaxation of supercoiled DNA. Subconfluent or postconfluent CaSki human cervical carcinoma cells were exposed to CPT (1-5000 ng/ml) and immediately X-irradiated (0-800 cGy). Cell survival was determined by clonogenic assay. RESULTS Mean topo I activity in cervical cancer (3.0 +/- 0.06 h(-1)) was significantly greater than in normal cervix tissue (0.29 +/- 0.06 h(-1)). Stage 3 and 4 cervical carcinoma specimens displayed a trend of greater topo I activity (5.88 +/- 3.7 h(-1)) than stage 1 and 2 tumors (2.57 +/- 0.47 h(-1)). No correlation between topo I protein levels and catalytic activity was found. Combined treatment of subconfluent CaSki cells with CPT and ionizing radiation resulted in additive killing of cells. Combined treatment of postconfluent CaSki cells with low doses of radiation (200 and 400 cGy) and 1 or 10 ng/ml CPT for 2 or 48 h produced significant cytotoxicity compared to CPT or radiation alone, which were ineffective at these doses. CONCLUSIONS Topo I activity is elevated in cervical cancer compared to normal cervix. The radiosensitivity of noncycling cells within cervical tumors may be increased by simultaneous treatment with low doses of CPT or other topo I inhibitors.

Abstract
Conventional chromosome in situ hybridization procedures rely on fixation to glass slides followed by microscopic evaluation. This report describes the development of a microdrop in situ hybridization to chromosomes in suspension. Chromosomes encapsulated in gel microdrops (GMDs) composed of an agarose matrix withstood stringent hybridization and denaturation conditions. Because of the increased stability, hybridization to encapsulated chromosomes was detected by flow cytometry as well as conventional microscopy. Thus, the MISH method offers a means for chromosome hybridization without slides and may enable identification and isolation of chromosome using hybridization rather than nucleic acid binding dyes.

Abstract
Gastric xanthelasmas are macroscopically well demarcated yellow or yellow-white plaques, and microscopically composed of typical foamy macrophages. Of 3870 patients who underwent upper gastrointestinal panendoscopic examinations, 30 (0.8%) were found to have gastric xanthelasma. A moderate predominance of males over females (M:F = 3.3:1) was noted. The age ranged between 21 and 69 years (mean 46.7). Frequency peaked in those from 40 to 60 years of age (53.3%). Single lesions were found in 26 patients and multiple in 4, with diameters of 1-6 mm, nearly 66.7% of which were 2-3 mm. Gastric xanthelasmas are most frequently found in the antrum (67.8%), especially along the lesser curvature. Associated chronic gastritis in the xanthelasma surrounding mucosa was found in the 30 patients and intestinal metaplasia in 4 (13.3%). The cause of gastric xanthelasma is unknown, but chronic gastritis may be the most plausible etiologic factor.

Abstract
One rare case of Waldenström's macroglobulinemia with massive right-sided pleural effusion is reported. A 66-year-old woman was admitted to our hospital because of exertional dyspnea and chronic cough of three months' duration. Chest X-ray examination showed massive right-sided pleural effusion. Routine blood examination revealed severe anemia. Sternal bone marrow aspirate revealed a hypercellular marrow with replacement of 50% of the normal hematopoietic cells by a spectrum of lymphoid cells, including small lymphocytes, a few plasma-cytoid lymphocytes and immature plasma cells. The diagnosis was confirmed by serum protein electrophoresis and immunoglobulin assay. The effect of chemotherapy was satisfactory in the first two years as pleural effusion subsided completely and the marrow returned to near normal. But, the response was poor during the last 6 months. She died about 4 years after her first admission.
