Abstract
Social novelty is a cognitive process that is essential for animals to interact strategically with conspecifics based on their prior experiences. The commensal microbiome in the gut modulates social behavior through various routes, including microbe-derived metabolite signaling. Short-chain fatty acids (SCFAs), metabolites derived from bacterial fermentation in the gastrointestinal tract, have been previously shown to impact host behavior. Herein, we demonstrate that the delivery of SCFAs directly into the brain disrupts social novelty through distinct neuronal populations. We are the first to observe that infusion of SCFAs into the lateral ventricle disrupted social novelty in microbiome-depleted mice without affecting brain inflammatory responses. The deficit in social novelty can be recapitulated by activating calcium/calmodulin-dependent protein kinase II (CaMKII)-labeled neurons in the bed nucleus of the stria terminalis (BNST). Conversely, chemogenetic silencing of the CaMKII-labeled neurons and pharmacological inhibition of fatty acid oxidation in the BNST reversed the SCFAs-induced deficit in social novelty. Our findings suggest that microbial metabolites impact social novelty through a distinct neuron population in the BNST.

Abstract
BACKGROUND/AIM Identifying pathogens with culture-negative pyogenic spondylitis is difficult. Shotgun metagenomic sequencing is an unbiased and culture-free approach in the diagnosis of infectious diseases. There are, however, a variety of contaminating factors that can confound the precision of metagenomic sequencing. CASE REPORT In a 65-year-old man suffering from culture-negative L3-5 spondylitis, metagenomics was applied to facilitate the diagnosis. The patient underwent percutaneous endoscopic lumbar discectomy. We applied metagenomic sequencing with a robust contamination-free protocol to the bone biopsy. By comparing the abundance for each taxon between the replicates and negative controls, we reliably identified Cutibacterium modestum as having a statistically higher abundance in all replicates. The patient's antibiotic therapy was switched to penicillin and doxycycline based upon the resistome analysis; the patient fully recovered. CONCLUSION This application of next-generation sequencing provides a new perspective in the clinical approach to spinal osteomyelitis and illustrates the potential of this technique in rapid etiological diagnosis.

Abstract
Previous studies have explored the role of the microbiome in attention-deficit/hyperactivity disorder (ADHD). However, whether the microbiome is correlated with emotional-behavioral disturbances, the most common comorbid symptom of ADHD, remains unclear. We established a cross-sectional study in which 6- to 18-year-old children with ADHD who were receiving no medication and a healthy control group of children without ADHD were recruited to analyze their microbiome composition. Microbiota of fecal samples were collected and analyzed using a 16s rRNA gene sequencing approach. In comparison with the healthy control group, the gut microbiota in children with ADHD exhibited significantly lower beta diversity. The abundance of the phylum Proteobacteria and the genera Agathobacter, Phascolarctobacterium, Prevotella_2, Acidaminococcus, Roseburia, and Ruminococcus gnavus group was increased in the ADHD group compared with the healthy group. Linear discriminant effect size (LEfSe) analysis was used to highlight specific bacteria phylotypes that were differentially altered between the ADHD and control groups. A regression analysis was performed to investigate the association between microbiota and emotional-behavioral symptoms in children with ADHD. A significant association was noted between withdrawal and depression symptoms and Agathobacter (p = 0.044), and between rule-breaking behavior and the Ruminococcus gnavus group (p = 0.046) after adjusting for sex, age, and the ADHD core symptoms score. This study advances the knowledge of how gut microbiota composition may contribute to emotional-behavioral symptoms in children with ADHD. The detailed mechanisms underlying the role of the gut microbiota in ADHD pathophysiology still require further investigation.

Abstract
OBJECTIVE Chronic obstructive pulmonary disease (COPD) is a global disease characterised by chronic obstruction of lung airflow interfering with normal breathing. Although the microbiota of respiratory tract is established to be associated with COPD, the causality of gut microbiota in COPD development is not yet established. We aimed to address the connection between gut microbiota composition and lung COPD development, and characterise bacteria and their derived active components for COPD amelioration. DESIGN A murine cigarette smoking (CS)-based model of COPD and strategies evaluating causal effects of microbiota were performed. Gut microbiota structure was analysed, followed by isolation of target bacterium. Single cell RNA sequencing, together with sera metabolomics analyses were performed to identify host responsive molecules. Bacteria derived active component was isolated, followed by functional assays. RESULTS Gut microbiota composition significantly affects CS-induced COPD development, and faecal microbiota transplantation restores COPD pathogenesis. A commensal bacterium Parabacteroides goldsteinii was isolated and shown to ameliorate COPD. Reduction of intestinal inflammation and enhancement of cellular mitochondrial and ribosomal activities in colon, systematic restoration of aberrant host amino acids metabolism in sera, and inhibition of lung inflammations act as the important COPD ameliorative mechanisms. Besides, the lipopolysaccharide derived from P. goldsteinii is anti-inflammatory, and significantly ameliorates COPD by acting as an antagonist of toll-like receptor 4 signalling pathway. CONCLUSION The gut microbiota-lung COPD axis was connected. A potentially benefial bacterial strain and its functional component may be developed and used as alternative agents for COPD prevention or treatment.

Abstract
This study examined the differences in factors affecting mortality between urban and rural areas in Taiwan. A retrospective study design was adopted by using the older adult health examination data during 2013-2019 from Hualien, Taiwan. The overall mortality risk in rural areas was significantly higher than urban areas. However, there was no significant difference in the mortality risk between the urban and rural older adults with unhealthy behaviors. Betel nut chewing was a significant risk factor of mortality among the rural older adults, while alcohol consumption was a protective factor; smoking, hepatitis C, and mental illness were significant risk factors among the urban older adults. The rural older adults had a higher rate of death from heart disease and lower rate of death from sepsis than the urban older adults. This study highlights the importance of individualized health promotion strategies for urban and rural areas for reducing mortality from disease.

Abstract
The association between the gut microbiota and the development of lupus is unclear. We investigated alterations in the gut microbiota after induction of lupus in a murine model using viral peptide of human cytomegalovirus (HCMV). Three treatment arms for the animals were prepared: intraperitoneal injection of HCMVpp65 peptide, adjuvant alone, and PBS injection. Feces were collected before and after lupus induction biweekly for 16S rRNA sequencing. HCMVpp65 peptide immunization induced lupus-like effects, with higher levels of anti-dsDNA antibodies, creatinine, proteinuria, and glomerular damage, compared with mice treated with nothing or adjuvant only. The Simpson diversity value was higher in mice injected with HCMVpp65 peptide, but there was no difference in ACE or Chao1 among the three groups. Statistical analysis of metagenomic profiles showed a higher abundance of various families (Saccharimonadaceae, Marinifiaceae, and Desulfovibrionaceae) and genera (Candidatus Saccharimonas, Roseburia, Odoribacter, and Desulfovibrio) in HCMVpp65 peptide-treated mice. Significant correlations between increased abundances of related genera (Candidatus Saccharimonas, Roseburia, Odoribacter, and Desulfovibrio) and HCMVpp65 peptide immunization-induced lupus-like effects were observed. This study provides insight into the changes in the gut microbiota after lupus onset in a murine model.

Abstract
Background: The development of nursing students’ ability to practice humanistic care is extremely important. Methods: This study explored students’ learning experience when providing humanistic care for older adults with chronic diseases while employing intergenerational narrative learning. An exploratory descriptive qualitative study design was adopted. Results: We analyzed evaluations from 35 students who completed the course, in which intergenerational narrative learning was employed. Evaluations contained open-ended questions that asked students to reflect upon their experiences and describe their perceptions, thoughts, and feelings after the course. Three main themes were revealed by thematic analysis: direct interaction supersedes knowledge in books, the framework for improving humanistic caring, and internalization of the importance of humanistic care in nursing. Conclusion: An awareness of patients’ perspectives inspired the students in their development toward a more profound caring attitude. The intergenerational narrative learning teaching strategy could foster professional and humanistic-centered care in nursing students.

Abstract
SCOPE A causal relationship between circadian misalignment and microbiota dysbiosis has been discussed recently, due to their association to pathogenesis. Herein, the possible impact of pterostilbene (PSB) and resveratrol (RES) on the gut microbiota brought by chronic jet-lag in mice is investigated. METHODS AND RESULTS Dietary supplement of RES and PSB (0.25%) are given to 16 week-jetlagged mice to examine the effects on microbiota and physiological functions. Jetlag significantly induces weight gained that could be effectively prevented by PSB. Both supplements also retain oscillation patterns that found to be lost in jetlag induced (JLG) group, including serum biochemical parameters and gut microbiota. The results of beta diversity suggest the supplementations efficiently lead to distinct gut microbial composition as compared to JLG group. Besides, the supplementation forestalls some microbial elevation, such as Eubacterium ventriosum and Acetitomaculum. Growth of health beneficial bacteria like Blautia and Lachnospiraceae UCG-001 is facilitated and abundance of these bacteria could be correlated to oscillation of biochemical parameters. Result of KEGG indicates distinct effect brought by microbial re-shaping. CONCLUSION The result suggests that supplementation of RES and PSB could potentially dampen some adverse effects of gut microbiota dysbiosis, and at the same time, re-composite and facilitate the growth of health beneficial microbiota.

Abstract
Background Gut microbiome has been associated with the efficacy of immune checkpoint inhibitors (ICI) in patients with various types of cancers but not yet in hepatocellular carcinoma (HCC). Aims To investigate the association between gut microbiome and efficacy of ICI in patients with HCC. Methods Patients with HCC who were scheduled to receive ICI were prospectively enrolled. Fecal samples were collected within 7 days before initiation of ICI (baseline) and 8 weeks later. Gut microbiome was assessed using 16S rRNA sequencing and shotgun whole-genome sequencing and correlated with objective response (complete or partial response), disease control (objective response or stable disease for ≥16 weeks), and overall survival. Results Thirty-six patients with HCC were enrolled, and 20 of them provided both baseline and 8-week feces. Alpha diversity, richness, and compositions of baseline gut microbiome indicated no difference between responders and nonresponders or between disease control and nondisease control groups. For the 20 paired feces, immunotherapy did not change any of the major microbiome features. No specific taxa were enriched in patients with objective response. Three taxa-Bifidobacterium, Coprococcus, and Acidaminococcus-were enriched in patients with disease control. However, the baseline abundance of these three taxa did not predict overall survival benefit. Conclusions In this exploratory study, we failed to disclose any overt association of gut microbiome with the efficacy of ICI in patients with HCC. A larger prospective study is warranted for definite conclusion.

Abstract
The aim of the present study was to evaluate whether probiotic administration could slow declining renal function. C57BL/6 mice (6–8 weeks of age, male) were fed a diet supplemented with adenine to induce chronic kidney disease (CKD). The experimental groups were additionally supplemented with 109 colony-forming units (CFU)/day (high-dose) and 107 CFU/day (low-dose) probiotics containing Lactobacillus acidophilus (TYCA06), Bifidobacterium longum subspecies infantis (BLI-02), and B. bifidum (VDD088). Renal function and histology were examined. Patients with stage 3–5 CKD and not on dialysis were recruited from July 2017 to January 2019. Two capsules of probiotics containing 2.5 × 109 CFU with the same composition were administered twice daily for 6 months. The decline in the estimated glomerular filtration rate (eGFR) was measured before and after the intervention. In addition, changes in the serum endotoxin and cytokine levels, gastrointestinal symptom scores, and the stool microbiota were measured. Probiotics could attenuate renal fibrosis and improve renal function in CKD mice. Thirty-eight patients completed the 6-month study. The mean baseline eGFR was 30.16 ± 16.52 ml/min/1.73 m2. The rate of decline in the eGFR was significantly slower, from −0.54 (−0.18, −0.91) to 0.00 (0.48, −0.36) ml/min/1.73 m2/month (P = 0.001) after 6 months of treatment. The serum levels of TNF-α, IL-6, IL-18, and endotoxin were significantly decreased after probiotic administration. Borborygmus and flatulence scores, as well as stool formation improved significantly. The abundance of B. bifidum and B. breve in the stool microbiota increased significantly. In conclusion, a combination of probiotics might attenuate renal function deterioration in CKD mice and human patients.

Abstract
e16165 Background: Immunotherapy with checkpoint inhibitors (ICI) is a promising treatment for unresectable hepatocellular carcinoma (HCC), but lack of effective biomarker to predict treatment response. Gut microbiome could modulate tumor response to immunotherapy in melanoma; but its effects on HCC are still unclear. Methods: From May 2018 to April 2020, 94 patients received ICI treatment for unresectable HCC (uHCC) in Taipei Veterans General Hospital, the feces samples were prospectively collected before ICI treatment. Finally, 20 patients with radiology proven objective tumor responses (OR; 3 complete responses and 17 partial responses) following immunotherapy, and 21 randomly selected patients with progressive disease (PD) were enrolled for fecal microbiota and metabolites investigation. In addition, feces from 17 healthy volunteers were taken as normal control. Results: Although the alpha diversity was not significantly different among groups, the principal component analysis of Bray-Curtis distance showed a significant clustering of fecal microbiota between HCC patients and healthy volunteers. The significant bacterial dissimilarity was observed between OR and PD patients following immunotherapy (p = 0.016 and 0.019 by Anoism and Adonis tests, respectively). According to linear discriminant analysis (LDA) effect size (LEfSe), a prominence of Prevotella usually regarded as a pathogenic bacterium, was more abundant in HCC patients with PD to ICI treatment. While Veillonella, Lachnospiraceae, Lachnoclostridium, Lactobacillales, Streptococcaceae and Ruminococcaceae were predominant in patients with OR (LDA score [log10] > 3). In addition, primary bile acids, including murocholic acid, α and β-muricholic acids, and secondary bile acids, including ursodeoxycholic acid, ursocholic acid, tauro-ursodeoxycholic acid, and taurohyocholic acid were significantly dominant in the feces of patients with OR to ICI treatment. Correlation network analysis in patients with OR showed significant linkages between Lachnoclostridium, Ruminococcus and secondary bile acids. Conclusions: Fecal microbiota and bile acids are associated with the response to immunotherapy for uHCC patients. These findings highlight the potential role of microbiota as a biomarker and strategy to enhance response to immunotherapy by modifying gut microbiota for uHCC.

Abstract
Most microbiome studies of dairy cows have investigated the compositions and functions of rumen microbial communities in lactating dairy cows. The importance of the relationships among hosts, microbiota, diet composition, and milk production remains unknown in dry dairy cows. Thus, in the present study, the composition of the rumen microbiome in cows from three dairy farms was investigated to identify core bacteria contributing to various physiological roles during rumen fermentation in dry dairy cows. The results indicated that ruminal fluid in dry dairy cows from different regional farms had core rumen microbiota that could be clearly distinguished from that of cows of the other farms. Further identification of key microorganisms associated with each farm revealed that Prevotella, Methanobrevibacter, Pseudobutyrivibrio, Ruminococcus, Bacteroides, and Streptococcus were major contributors. Spearman's correlation indicated that the abundance of genera such as Prevotella and Ruminococcus in dry dairy cows could indicate milk yield in the previous lactating period. Functional pathway analysis of the rumen bacterial communities demonstrated that amino acid metabolism and carbohydrate metabolism were the major pathways. Our findings provide knowledge of the composition and predicted functions of rumen microbiota in dry dairy cows from regional farms, which underscore the importance of the relationships among hosts, microbiota, diet composition, and milk production.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is the most common cause of liver disease due to lipid accumulation in the hepatocyte. Diet, especially a high-fat diet, is one risk factor that leads to NAFLD. Many natural compounds such as isoflavones have antiobesity effects. Therefore, intake of these functional compounds through daily dietary choices is a method of improving health. Miso is a kind of fermented soy paste, which is rich in isoflavones and has a different biological activity. In this study, we investigated the effects of different concentrations of fermented soy paste on NAFLD in high-fat-diet (HFD)-fed Sprague-Dawley (SD) rats. The results showed that 2% fermented soy paste decreased serum triacylglycerol (TG) and alanine aminotransferase (ALT) and reduced lipid accumulation in the liver through induced fatty acid oxidation by activating the adenosine 5'-monophosphate -activated protein kinase (AMPK) pathway and increasing PGC1α and CPT1α protein expression. Furthermore, we found that 2% fermented soy paste increased the abundance of Prevotellaceae NK3B31 and Desulfovibrio. Taken together, fermented soy paste improved HFD-induced lipid accumulation in the liver by activating fatty acid oxidation and modulating gut microbiota.

Abstract
Chronic kidney disease (CKD) is a serious healthcare dilemma, associated with specific changes in gut microbiota and circulating metabolome. Yet, the functional capacity of CKD microbiome and its intricate relationship with the host metabolism at different stages of disease are less understood. Methods: Here, shotgun sequencing of fecal samples and targeted metabolomics profiling of serum bile acids, short- and medium-chain fatty acids, and uremic solutes were performed in a cohort of CKD patients with different severities and non-CKD controls. Results: We identified that levels of 13 microbial species and 6 circulating metabolites were significantly altered across early to advanced stages or only in particular stage(s). Among these, Prevotella sp. 885 (decreased) was associated with urea excretion, while caproic acid (decreased) and p-cresyl sulfate (elevated) were positively and negatively correlated with the glomerular filtration rate, respectively. In addition, we identified gut microbial species linked to changes in circulating metabolites. Microbial genes related to secondary bile acid biosynthesis were differentially abundant at the early stage, while pathway modules related to lipid metabolism and lipopolysaccharide biosynthesis were enriched in the CKD microbiome at the advanced stage, suggesting that changes in microbial metabolism and host inflammation may contribute to renal health. Further, we identified metagenomic and metabolomic markers to discriminate cases of different severities from the controls, among which Bacteroides eggerthii individually was of particular value in early diagnosis. Conclusions: Our dual-omics data reveal the connections between intestinal microbes and circulating metabolites perturbed in CKD, which may be of etiological and diagnostic importance.

Abstract
The interplay of the gut microbes with gut-producing nephrotoxins and the renal progression remains unclear in large human cohort. Significant compositional and functional differences in the intestinal microbiota (by 16S rRNA gene sequencing) were noted among 30 controls and 92 (31 mild, 30 moderate and 31 advanced) patients at different chronic kidney disease (CKD) stages (discovery cohort). A core CKD-associated microbiota consisted of 7 genera (Escherichia_Shigella, Dialister, Lachnospiraceae_ND3007_group, Pseudobutyrivibrio, Roseburia, Paraprevotella and Ruminiclostridium) and 2 species (Collinsella stercoris and Bacteroides eggerthii) were identified to be highly correlated with the stages of CKD. Paraprevotella, Pseudobutyrivibrio and Collinsella stercoris were superior in discriminating CKD from the controls than the use of urine protein/creatinine ratio, even at early-stage of disease. The performance was further confirmed in a validation cohort comprising 22 controls and 76 peritoneal dialysis patients. Bacterial genera highly correlated with indoxyl sulfate and p-cresyl sulfate levels were identified. Prediction of the functional capabilities of microbial communities showed that microbial genes related to the metabolism of aromatic amino acids (phenylalanine, tyrosine, and tryptophan) were differentially enriched among the control and different CKD stages. Collectively, our results provide solid human evidence of the impact of gut-metabolite-kidney axis on the severity of chronic kidney disease and highlight a usefulness of specific gut microorganisms as possible disease differentiate marker of this global health burden.

Abstract
BACKGROUND A comprehensive metabolomics-based approach to address the impact of specific gut microbiota on allergen sensitization for childhood rhinitis and asthma is still lacking. METHODS Eighty-five children with rhinitis (n = 27) and with asthma (n = 34) and healthy controls (n = 24) were enrolled. Fecal metabolomic analysis with 1 H-nuclear magnetic resonance (NMR) spectroscopy and microbiome composition analysis by bacterial 16S rRNA sequencing were performed. An integrative analysis of their associations with allergen-specific IgE levels for allergic rhinitis and asthma was also assessed. RESULTS Amino acid, β-alanine, and butanoate were the predominant metabolic pathways in the gut. Among them, amino acid metabolism was negatively correlated with the phylum Firmicutes, which was significantly reduced in children with rhinitis and asthma. Levels of histidine and butyrate metabolites were significantly reduced in children with rhinitis (P = 0.029) and asthma (P = 0.009), respectively. In children with asthma, a reduction in butyrate-producing bacteria, including Faecalibacterium and Roseburia spp., and an increase in Clostridium spp. were negatively correlated with fecal amino acids and butyrate, respectively (P < 0.01). Increased Escherichia spp. accompanied by increased β-alanine and 4-hydroxybutyrate appeared to reduce butyrate production. Low fecal butyrate was significantly associated with increased total serum and mite allergen-specific IgE levels in children with asthma (P < 0.05). CONCLUSION A reduced fecal butyrate is associated with increased mite-specific IgE levels and the risk of asthma in early childhood. Fecal β-alanine could be a specific biomarker connecting the metabolic dysbiosis of gut microbiota, Clostridium and Escherichia spp., in childhood asthma.

Abstract
Background This study examined how intracranial large artery stenosis (ILAS), symptomatic and asymptomatic ILAS, and risk factors affect unfavorable outcome events after medical treatment in routine clinical practice. Methods This was a 24-month prospective observational study of consecutively recruited stroke patients. All participants underwent magnetic resonance angiography, and their clinical characteristics were assessed. Outcome events were vascular outcome, recurrent stroke, and death. Cox regression analyses were performed to identify potential factors associated with an unfavorable outcome, which included demographic and clinical characteristics, the risk factors, and stenosis status. Results The analysis included 686 patients; among them, 371 were assessed as ILAS negative, 231 as symptomatic ILAS, and 84 as asymptomatic ILAS. Body mass index (p < .05), hypertension (p = .01), and old infarction (p = .047) were factors relating to vascular outcomes. Hypertension was the only factor for recurrent stroke (p = .035). Poor glomerular filtration rate (< 30 mL/min/1.73 m2) (p = .011) and baseline National Institutes of Health Stroke Scale scores (p < .001) were significant predictors of death. Conclusions This study extended previous results from clinical trials to a community-based cohort study by concurrently looking at the presence/absence of stenosis and a symptomatic/asymptomatic stenotic artery. Substantiated risk factors rather than the stenosis status were predominant determinants of adverse outcome. Although the degree of stenosis is often an indicator for treatment, we suggest risk factors, such as hypertension and renal dysfunction, should be monitored and intensively treated.

Abstract
Low response rate and recurrence are common issues in lung cancer; thus, identifying a potential compound for these patients is essential. Utilizing an in silico screening method, we identified withaferin A (WA), a cell-permeable steroidal lactone initially extracted from Withania somnifera, as a potential anti-lung cancer and anti-lung cancer stem-like cell (CSC) agent. First, we demonstrated that WA exhibited potent cytotoxicity in several lung cancer cells, as evidenced by low IC50 values. WA concurrently induced autophagy and apoptosis and the activation of reactive oxygen species (ROS), which plays an upstream role in mediating WA-elicited effects. The increase in p62 indicated that WA may modulate the autophagy flux followed by apoptosis. In vivo research also demonstrated the anti-tumor effect of WA treatment. We subsequently demonstrated that WA could inhibit the growth of lung CSCs, decrease side population cells, and inhibit lung cancer spheroid-forming capacity, at least through downregulation of mTOR/STAT3 signaling. Furthermore, the combination of WA and chemotherapeutic drugs, including cisplatin and pemetrexed, exerted synergistic effects on the inhibition of epidermal growth factor receptor (EGFR) wild-type lung cancer cell viability. In addition, WA can further enhance the cytotoxic effect of cisplatin in lung CSCs. Therefore, WA alone or in combination with standard chemotherapy is a potential treatment option for EGFR wild-type lung cancer and may decrease the occurrence of cisplatin resistance by inhibiting lung CSCs.

Abstract
Telecare is defined as care practiced at a distance. It is an effective strategy for improving the self-health care management of home-patients with chronic diseases. The purpose of this study was to explore the intent to use of telehealth patients. The correlation between the self-care behaviors, the intent to use of telehealth, and the effects on physiological indicators of patients with chronic disease at home were studied. A cross-sectional study design employing purposive sampling was selected. The structured questionnaire ‘Telecare Usage Intention Scale and Self-Care Behavior Scale’ were used, ‘HbA1c, glucose levels and monthly blood pressure measurements’ were analyzed in this thirteen month study. The self-care behaviors of the participants were positively correlated with their intent to use telehealth (p < 0.01). The results also indicated that HbA1c, glucose levels and frequency BP measurement of the participants improved significantly after using telecare (p < 0.005). The results indicated a strong intent to use telehealth and positive perception of telecare services by in-home patients with a chronic disease. Telehealth improves the self-care behavior of in-home chronic disease patients and enhances medical professionals’ ability to deliver quality and effective healthcare.

Abstract
We investigate the coupling of dipole resonances induced in a heteromaterial system composed of a high-refractive-index nanoparticle and a highly reflective substrate. A broad scattering signal and strong electric near-field enhancement in the near-infrared region are generated by a hybrid Si nanoparticle on a gold-film system under oblique illumination. Dark-field microscopy investigations of the scattering signal measurement reveal the resonance shifts of the dipole mode of silicon nanoparticles on gold films. Further, the scattering signal is enhanced for p-polarized illumination in the near-infrared region. The results indicate that the coupling of Si nanoparticles on a gold-film system facilitates a possible application for both surface-enhanced fluorescence and surface-enhanced Raman scattering.

Abstract
RATIONALE Cancer stem cell (CSC) theory has drawn much attention, with evidence supporting the contribution of stem cells to tumor initiation, relapse, and therapy resistance. OBJECTIVES To screen drugs that target CSCs to improve the current treatment outcome and overcome drug resistance in patients with lung cancer. METHODS We used publicly available embryonic stem cell and CSC-associated gene signatures to query the Connectivity Map for potential drugs that can, at least in part, reverse the gene expression profile of CSCs. High scores were noted for several phenothiazine-like antipsychotic drugs, including trifluoperazine. We then treated lung CSCs with different EGFR mutation status with trifluoperazine to examine its anti-CSC properties. Lung CSCs resistant to epidermal growth factor receptor-tyrosine kinase inhibitor or cisplatin were treated with trifluoperazine plus gefitinib or trifluoperazine plus cisplatin. Animal models were used for in vivo validation of the anti-CSC effect and synergistic effect of trifluoperazine with gefitinib. MEASUREMENTS AND MAIN RESULTS We demonstrated that trifluoperazine inhibited CSC tumor spheroid formation and down-regulated the expression of CSC markers (CD44/CD133). Trifluoperazine inhibited Wnt/β-catenin signaling in gefitinib-resistant lung cancer spheroids. The combination of trifluoperazine with either gefitinib or cisplatin overcame drug resistance in lung CSCs. Trifluoperazine inhibited the tumor growth and enhanced the inhibitory activity of gefitinib in lung cancer metastatic and orthotopic CSC animal models. CONCLUSIONS Using in silico drug screening by Connectivity Map followed by empirical validations, we repurposed an existing phenothiazine-like antipsychotic drug, trifluoperazine, as a potential anti-CSC agent that could overcome epidermal growth factor receptor-tyrosine kinase inhibitor and chemotherapy resistance.

Abstract
Tumor recurrence is the most common cause of disease failure after surgical resection in early-stage lung adenocarcinoma. Identification of clinically relevant prognostic markers could help to predict patients with high risk of disease recurrence. A meta-analysis of available lung adenocarcinoma microarray datasets revealed that T-LAK cell-originated protein kinase (TOPK), a serine/threonine protein kinase, is overexpressed in lung cancer. Using stable cell lines with overexpression or knockdown of TOPK, we have shown that TOPK can promote cell migration, invasion, and clonogenic activity in lung cancer cells, suggesting its crucial role in lung tumorigenesis. To evaluate the prognostic value of TOPK expression in resected stage I lung adenocarcinoma, a retrospective analysis of 203 patients diagnosed with pathological stage I lung adenocarcinoma was carried out to examine the expression of TOPK by immunohistochemistry (IHC). The prognostic significance of TOPK overexpression was examined. Overexpression of TOPK (IHC score >3) was detected in 67.0% of patients, and these patients were more frequently characterized with disease recurrence and angiolymphatic invasion. Using multivariate analysis, patient age (>65 years old; P = 0.002) and TOPK overexpression (IHC score >3; P < 0.001) significantly predicted a shortened overall survival. Moreover, TOPK overexpression (IHC score >3; P = 0.005) also significantly predicted a reduced time to recurrence in the patients. Our results indicate that overexpression of TOPK could predetermine the metastatic capability of tumors and could serve as a significant prognostic predictor of shortened overall survival and time to recurrence.

Abstract
BACKGROUND Schizophrenia, bipolar disorder, and major depression are devastating mental diseases, each with distinctive yet overlapping epidemiologic characteristics. Microarray and proteomics data have revealed genes which expressed abnormally in patients. Several single nucleotide polymorphisms (SNPs) and mutations are associated with one or more of the three diseases. Nevertheless, there are few studies on the interactions among the disease-associated genes and proteins. RESULTS This study, for the first time, incorporated microarray and protein-protein interaction (PPI) databases to construct the PPI network of abnormally expressed genes in postmortem brain samples of schizophrenia, bipolar disorder, and major depression patients. The samples were collected from Brodmann area (BA) 10 of the prefrontal cortex. Abnormally expressed disease genes were selected by t-tests comparing the disease and control samples. These genes were involved in housekeeping functions (e.g. translation, transcription, energy conversion, and metabolism), in brain specific functions (e.g. signal transduction, neuron cell differentiation, and cytoskeleton), or in stress responses (e.g. heat shocks and biotic stress).The diseases were interconnected through several "switchboard"-like nodes in the PPI network or shared abnormally expressed genes. A "core" functional module which consisted of a tightly knitted sub-network of clique-5 and -4s was also observed. These cliques were formed by 12 genes highly expressed in both disease and control samples. CONCLUSIONS Several previously unidentified disease marker genes and drug targets, such as SBNO2 (schizophrenia), SEC24C (bipolar disorder), and SRRT (major depression), were identified based on statistical and topological analyses of the PPI network. The shared or interconnecting marker genes may explain the shared symptoms of the studied diseases. Furthermore, the "switchboard" genes, such as APP, UBC, and YWHAZ, are proposed as potential targets for developing new treatments due to their functional and topological significance.

Abstract
Abstract
Signal transduction pathways at cellular level require massive protein-protein interactions (PPIs) in response to different environmental cues. Diverse experimental techniques for detecting PPIs have been developed; however, the large amount of data accumulated from various sources has posed a grand challenge in data reliability for PPI. To evaluate the role of PPIs within signaling pathways, we have systematic profiled PPI residing in 28 KEGG pathways, for example mTOR, MAPK, Wnt, VEGF, and Hedgehog, and 3 cancer-related pathways stored in KEGG (http://www.genome.jp/kegg/). Of ∼60000 human PPI collected, 2786 PPI can be detected within targeted 14 pathways. To validate these PPIs, we used a newly developed Proximity Ligation Assay, which detects endogenous PPI through a pair of antibodies that bind to proteins in close proximity. Each PPI can be made visible through DNA amplification and quantified by counting fluorescent dots in the cell. Of 1,204 PPIs examined, 557 PPIs can be confirmed in HeLa cells. Specifically, 383 out of 557 validated PPIs residing within pathways in cancer and mTOR, Wnt and MAPK pathways are considered novel “links” based on annotations of KEGG. Moreover, 79 validated PPIs are cross-talk events among 35 signaling transduction and cancer related pathways. Surprisingly, only 16 PPIs (out of 557 confirmed PPIs) are highly correlated in 7 sets of cancer cells from NCI60 microarray dataset. In this large scale PPI profiling, 41 apoptosis related PPIs were further tested in 3 cancer cell lines to explore the possibility for drug screening. These systematic analyses of endogenous PPI pairs within and between pathways may set the foundation to disrupt the signaling pathways by targeting PPIs in cancer drug discovery.

Abstract
Sensitization of vagal lung C fibers has been postulated to contribute to the development of asthma, but support for this notion is still lacking. We investigated the characteristics and function of pulmonary C fibers (PCFs) in ovalbumin (OVA)-sensitized Brown Norway rats, an established animal model of asthma. Rats were sensitized with intraperitoneal injection of OVA or were treated with saline (control). In study 1, with the use of open-chest and artificially ventilated rats, inhalation of 5% OVA aerosol evoked an augmented increase in total lung resistance in the OVA-sensitized rats, compared with the control rats. Bilateral vagotomy or subcutaneous pretreatment with a high-dose of capsaicin for blocking of C-fiber function equally attenuated this augmented total lung resistance response, suggesting the involvement of PCFs. In study 2, with the use of anesthetized, spontaneously breathing rats, right atrial injection of capsaicin (1 microg/kg; a PCF stimulant) evoked an augmented apneic response in the OVA-sensitized rats, compared with the control rats. In study 3, with the use of open-chest, paralyzed, and artificially ventilated rats, the afferent PCF responses to right atrial injection of capsaicin (0.5 and 1.0 microg/kg), phenylbiguanide (8 microg/kg; a PCF stimulant), or adenosine (0.2 mg/kg; a PCF stimulant) were enhanced in the OVA-sensitized rats, compared with the control rats. However, the baseline activities of PCFs and their afferent responses to mechanical stimulation by lung hyperinflation in the OVA-sensitized and control rats were comparable. Our results suggested that OVA-sensitized Brown Norway rats possess sensitized vagal PCFs, which may participate in the development of the airway hyperreactivity observed in these animals.

Abstract
Twelve Gram-positive phthalate ester degraders were isolated from soil. Using Biolog GP2 plates, eight of them were identified as belonging to the Corynebacterium-Mycobacterium-Nocardia group, while the remaining four were unidentifiable. When cultured in the presence of di-butyl-phthalate (DBP) in basal salts solution, five of these isolates accomplished more than 90% of DBP degradation within 48 h (fast group), three were placed in the medium group, and the remaining four were placed in the slow group which caused less than 30% of DBP degradation within the same period of time. A 420 bp DNA fragment was amplified from six isolates and none of them fell within the slow group. When compared with the large subunit of phthalate dioxygenase gene (phtA) of Arthrobacter keyseri, 83% and 91% similarities were evident in the nucleotide and amino acid sequences, respectively. However, no correlation between cell surface hydrophobicity and phthalate degradation ability was evident. Six surfactants (Brij 30, Brij 35, Tergitoltype NP-10, Triton N-101, Triton X-100 and SDS) were tested for their abilities to increase degradation rate. When added at the critical micellar concentration (CMC), they all displayed strong growth inhibition against the three bacteria tested, with Brij 30 been the least toxic to isolates G2 and G11, and Brij 35 had the least inhibitory effect for G1. When half the CMC of Brij 30 was incorporated into the basal salts, the inhibitory effect on DBP degradation remained. Soil helped to minimize surfactant toxicity of surfactant and increase the degradation potential of some of the test bacteria. When DBP-amended soil had been aged for three months, decreases in bioavailability were observed but the effect varied tremendously between different organisms. For isolates G1, G2, G5, G7 and G17 the aging effects were almost non-exist. The present study indicates that selection of a suitable degrader may minimize the undesired effect of aging on bioremediation process.

Abstract
Hyperglycemia after stress is a very common clinical phenomenon. It is generally hypothesized that the underlying cause is a neuroendocrine-mediated deterioration in glucose metabolism. However, the detailed roles of insulin sensitivity, glucose effectiveness and acute insulin response to glucose load in response to stress have not been well established. Hernioplasty was used as a minor stress model for studying stress-induced hyperglycemia. Eleven healthy young men were enrolled voluntarily in this study. Their mean age was 22.0 +/- 0.9 yr and BMI 23.3 +/- 0.6 kg/m2. Frequently sampled i.v. glucose tolerance tests were performed one day before and one day after the surgery. Insulin sensitivity (SI), glucose effectiveness (EG) and area under acute insulin response (AIR) were calculated from "minimal model" algorithms. We also measured fasting concentrations of human GH, ACTH and F on the days of the test. Compared to the pre-operation data, levels of ACTH and F did not change significantly after the surgery. Only GH levels were marginally significant. On the other hand, the SI (0.75 +/- 0.1, 0.52 +/- 0.9 x 10(-5) min(-1)/pmol, p = 0.04), EG (0.023 +/- 0.03, 0.016 +/- 0.003 min(-1), p = 0.01) and AIR (6738.5 +/- 1111.6, 5130.0 +/- 1047.2 pmol, p = 0.005) were all significantly decreased after surgery. The percentages of decrease were 16.3 +/- 15.5, 32.1 +/- 10.3 and 17.8 +/- 10.3%, respectively. Finally, only the changes of EG positively correlate with the changes of ACTH before and after surgery. No significant changes were noted among other stress hormones and the changes of SI, EG and AIR. In conclusion, hernioplasty results in reduced SI, EG and AIR. Among them, although not statistically significant, the EG showed the most distinct decrease after the surgery, which has not been found in previous literature.

Abstract
Carcinoid tumors are uncommon tumors of the neuroendocrine system. They grow slowly and may remain silent for years before presenting with carcinoid syndrome. A diagnosis of asymptomatic carcinoid tumor is difficult. Wide resection of the primary tumor and metastatic lesions is the first choice of treatment. Primary carcinoid is sometimes distributed throughout the entire body, but it is rare in the spleen. We herein present a rare case of a symptomless carcinoid tumor that predominantly invaded the spleen with liver metastasis.

Abstract
There is a wide variety of disorders associated with thrombosis of the superior sagittal sinus (SSS), including infectious disease. noninfectious conditions such as vasculitis and hypercoagulable states, and complications arising from pregnancy or use of oral contraceptive medications. Despite these well-defined associations, approximately 25% of the cases remain idiopathic. In this article the authors describe a patient who was found to have SSS thrombosis while experiencing a thyrotoxic phase of Graves disease. The patient presented with intracerebral hemorrhage, subarachnoid hemorrhage, seizure, coma, a raised fibrinogen concentration, low protein C activity, and atrial fibrillations. Thrombolysis was successfully performed despite the coexistence of thrombosis and intracranial hemorrhage. Patients with thyrotoxicosis and a diffuse goiter may be predisposed to the development of SSS thrombosis, as a result of hypercoagulation and stasis of local venous blood flow. In the present case, a patient in whom thrombosis coexisted with intracranial hemorrhage was successfully treated using thrombolytic therapy.

Abstract
Partial proteolysis of HTLV-1 Tax protein has revealed the region surrounding amino acid residues (88)KVL(90) to be highly exposed. The protein sequence surrounding this region ((81)QRTSKTLKVLTPPIT(95)) bears resemblance to the kinase-inducible domain (KID, (129)SRRPSYRKILNE(140)) of CREB and is involved in recruiting transcriptional coactivators, p300 and CBP, for trans-activating the viral long terminal repeat (LTR). Data have also revealed the KID-like region to be important for Tax binding to DNA. Here we report that single (K88A, V89A, L90A) and double alanine substitutions (V89A-L90A) in the (88)KVL(90) motif attenuate the ability of Tax to activate NF-kappaB. Deletions near or spanning this motif also had the same effect. The alanine substitutions affect HTLV-1 LTR activation and NF-kappaB activation differently, with K88A and V89A mutants showing much reduced activities for HTLV LTR activation while retaining attenuated but significant NF-kappaB-activating function. In contrast, although the L90A mutant is similarly attenuated for NF-kappaB activation, it showed significant activity in LTR trans-activation. Incorporation of both V89A and L90A substitutions in a V89A-L90A double mutant further reduced NF-kappaB activation and completely abrogated LTR trans-activation. In aggregate, these results demonstrate the importance of the KID-like domain of Tax and implicate its interaction with cellular factors other than p300/CBP in NF-kappaB activation.

Abstract
The human T-cell lymphotropic virus, type (HTLV)-1 trans-activator, Tax, coordinates with cAMP-responsive element-binding protein (CREB) and the transcriptional co-activators p300/CBP on three 21-base pair repeat elements in the proviral long terminal repeat (LTR) to promote viral mRNA transcription. Recruitment of p300/CBP to the activator-enhancer complex, however, is insufficient to support Tax-dependent LTR trans-activation. Here, we report that the p300/CBP-associated factor (P/CAF) is a critical and integral component of the functional HTLV-1 activator-enhancer complex. The HTLV-1 Tax protein directly binds P/CAF in vitro and co-immunoprecipitates with this co-activator in vivo. The Tax mutants (K88A and V89A) defective for p300/CBP-binding and LTR trans-activation, retained their abilities to interact with P/CAF. The M47 mutant (L319R, L320S) protein, which has previously been shown to interact with p300/CBP, by contrast, failed to form complexes with P/CAF and is impaired in LTR trans-activation. Furthermore, LTR trans-activation by Tax is competitively inhibited by the adenoviral E1A 12S gene product, which displaces P/CAF from p300/CBP and inhibits the histone acetyltransferase activities of both P/CAF and p300/CBP. This inhibition is partially reversed by exogenously added P/CAF. These results imply that simultaneous recruitment of two distinct co-activators (p300/CBP and P/CAF) by Tax is essential for the assembly of a trans-activation competent, nucleoprotein complex.

Abstract
To overcome the limitation of the microscope field, the study proposed an autostage sperm tracing system (ASTS), which could trace a particular sperm for a long time and distance. The ASTS was constructed by assembling a commercial microscope, an image frame grabber, a personal computer, and a motorized stage. Its performance was tested by evaluating 6 semen samples and by comparing the evaluation with those of other semen evaluations. The ASTS broke through the limitation of the microscope field and traced a particular sperm as long as possible. It analyzed the sperm track and calculated the motility parameters, such as curvilinear velocity (Vcl), straight-line velocity (Vsl), and linearity (L(in)). The sperm quality was then evaluated in real time, and the user could decide to capture or abandon a particular sperm in the IVF The ASTS enables users to evaluate sperm progression for a long time and to have the global quality of a particular sperm in real time. Its open structure has the flexibility for micromanipulating a semen sample, and has the potential application associated with a modern IVF technique.

Abstract
Cholecystokinin (CCK) plays an important role in regulating the biliary motility in herbivorous and carnivorous animals. Little is known about how the motility of the sphincter of Oddi (SO) is regulated through a somatic stimulation. It was our aim to test the hypothesis that somatic electrical nerve stimulation (SENS) affects SO motility in animals with different types of SO through CCK-related mechanisms. The activity of SO in anesthetized rabbits and cats was measured by using a continuously perfused open-tip manometric method. SENS was brought about by applying an electric current (2/15 Hz alternatively, 20 min) to two needles positioned near spinal nerves in the 6th and 7th intercostal space in the right midclavicular line. The SO motility before and X min after the start of SENS, designated as pre-SENS and SENS-X respectively, were recorded and saved in a computer equipped with off-line analysis software. The SO activity in rabbits, in terms of phasic contraction pressure and duration of summation peak during SENS were significantly higher than that before SENS. The phasic contraction pressure of pre-SENS, SENS-10, and SENS-16 were 6.83 +/- 0.39 mm Hg, 9.23 +/- 0.83 mm Hg and 10.46 +/- 0.81 mm Hg, respectively (P < 0.03, N = 13). The duration of summation peak in pre-SENS, SENS-10, and SENS-16 were 7.26 +/- 0.41 sec, 10.22 +/- 0.46 sec, and 13.49 +/- 2.31 sec, respectively (P < 0.05, N = 13). The SENS-induced SO hyperactivity was not inhibited by pretreatment with atropine, propranolol, phentolamine, or naloxone, but was blocked by pretreatment with the CCK receptor antagonist, proglumide, and by injection of anti-CCK-8 antibody during SENS in a dose-dependent manner. In contrast, SENS induced an inhibitory SO response in cats. However, in both circumstances, an obvious elevation of plasma CCK level determined by radioimmunoassay was noted after SENS. We conclude that SENS causes secretion of CCK, which in turn affects biliary tract motility in animals with different types of SO. This provides an easily applicable method for those patients who have hyperactive SO function.

Abstract
Many drugs act as sperm stimulants and are of clinical value for male infertility. Current research deals with the physiological mechanisms of sperm motility/sperm stimulation and how long the effect lasts. For such a study, long-term monitoring of sperm motility becomes essential for traditional semen evaluation. A new system was designed to deal with the microscopic images of semen. Its performance was evaluated by studying the effect of EDTA on sperm motility. EDTA increased sperm curvilinear velocity (Vcl) and straight-line velocity (Vsl) by 31 and 20%. EDTA also prolonged the duration of motility by 68 and 61%, respectively. However, EDTA had less effect on the linearity of forward progression (Lin). The proposed system can analyze semen and does well at monitoring sperm motility for short term and long term. It may be valuable to test the possible role of sperm stimulation for male infertility and assisted reproduction.

Abstract
The major surface promoter of human hepatitis B virus can produce three distinct groups of S transcripts. The initiation sites of these transcripts are in close proximity. Encompassing the ATG for the middle surface protein, the largest S transcript (+1) encodes the middle surface protein whereas the other two (+20 and +31) can only code for small surface protein. Sequence analysis does not reveal any TATA element. In this study, we employ deletion, linker scanning, and linker insertion analyses to study systematically the sequence requirements for the initiations of all three transcripts and their upstream regulatory sequences. Our study reveals that the sequence downstream of -16 is sufficient for precise initiation of all three groups of S transcripts. The 3' boundary of minimal promoter element is +15 for the +1 transcript, whereas it is +39 for both +20 and +31 transcripts. Furthermore, there are distinct sequence requirements for the initiations of three groups of S transcripts. The sequences from -17 to -10 and from -1 to +7 are required for the initiation of +1 transcript, the sequence from +16 to +39 is essential for the +20 transcript, and the sequences from -17 to -10 and from +24 to +39 are required for the + 31 transcript. Our results also suggest that the transcription initiations of major surface promoter may be mediated in part by initiators. The initiations of these three groups of S transcripts are under differential regulation. The region from -39 to -16 containing both negative and positive regulatory elements selectively regulates the transcription levels of the two major S transcripts. Most notably, mutation of the sequence from -17 to -10, which contains a Sp1 site, leads to an increase in the imprecise initiation at +1 site and depresses the initiation of +20 and, to a greater extent, +31 transcript. The relevance of differential regulation of major surface promoter to the varied production of different surface protein isoforms in viral life cycle is discussed.

Abstract
We have identified a novel 69-kD peptide autoantigen (ICA69) associated with insulin-dependent diabetes mellitus (IDDM) by screening a human islet lambda gt11 cDNA expression library with cytoplasmic islet cell antibody positive sera from relatives of IDDM patients who progressed to the overt disease. The deduced open reading frame of the ICA69 cDNA predicts a 483-amino acid protein. ICA69 shows no nucleotide or amino acid sequence relation to any known sequence in GenBank, except for two short regions of similarity with BSA. The ICA69 cDNA probe hybridizes with a 2-kb mRNA in poly(A+) RNA from human pancreas, brain, heart, thyroid, and kidney, but not with skeletal muscle, placenta, spleen, or ovary. Expression of ICA69 was also detected in beta cells and cell lines, as well as in tumoral tissue of islet cell origin. The native ICA69 molecule migrates to 69 kD in SDS-PAGE as detected with specific antibodies. Serum samples from relatives of IDDM patients specifically reacted with affinity-purified recombinant ICA69 on Western blotting. The structural gene for ICA69 was designated ICA1. A homologue in the mouse, designated Ica-1 was mapped to the proximal end of chromosome 6 (within 6 cM of the Met protooncogene). ICA69 adds a novel autoantigen to the family of identified islet target molecules, and by the manner of its identification and characterization large amounts of antigen are available for development of quantitative, convenient predictive assays for autoantibodies and analysis of the role of this molecule in diabetes autoimmunity, as well as its physiologic function.

Abstract
We prospectively studied 89 patients to assess the diagnostic use of renal allograft biopsy in the first three months after transplantation. These biopsies were done in patients in whom diagnosis was not clear or clinical rejection was deemed to be severe. Clinical diagnosis at initial biopsy was compared with the morphological diagnosis. To determine if morphological data improved the prognostic usefulness of the clinical data, we performed multiple logistic regression relating clinical variables at initial biopsy and histological changes in the transplant to the outcome of 120 patients one year after biopsy. The clinical and morphological diagnosis differed in 41 of 89 patients (46%). Of 120 patients in the prognostic study, 35 returned to dialysis during the first year following transplantation. Using multiple logistic regression, a categorical variable that took into account both the serum creatinine and its rate of change before biopsy was the best clinical predictor of return to dialysis. Further increase in chi 2 occurred with type of donor, number of transfusions, and age. Using the clinical variables we produced an index, from 0 to 1 to predict outcome. Only 8 had index less than 0.2, of whom 7 returned to dialysis. The best morphological predictor of outcome was interstitial hemorrhage. Further increase in chi 2 was obtained with vascular endothelial proliferation, glomerular endothelial swelling, and glomerular necrosis. With an index derived from the morphological variables only 11 had index less than 0.2, of whom 9 returned to dialysis. Combining both clinical and morphological data, the best predictor of return to dialysis was interstitial hemorrhage, followed by creatinine, glomerular endothelial swelling, and type of donor. Using both clinical and morphological variables we produced another index to predict outcome. A group of 65 patients had index greater than 0.8, of whom 63 (94%) did not return to dialysis, and 18 patients had index less than 0.2, 17 of whom returned to dialysis. The remaining 12 patients in the dialysis group and 15 in the nondialysis group had indices greater than 0.2 less than 0.8. We conclude that a transplant biopsy yields important diagnostic and prognostic information. Unexpected diagnoses were made in 46% of cases. The addition of morphological data to the clinical data available at time of biopsy greatly improved the prediction of return to dialysis.
