Abstract
Worldwide abuse of tetracycline (TC) seriously threatens environmental safety and human health. Metal-TC complexes formed by residual TC in the environment can also contribute to the spread of antibiotic resistance. Therefore, monitoring of TC residues is still required. Here, we report novel aggregation-induced emission carbon dots (AIE-Cdots) as nanoaggregate probes for the rapid and selective detection of TC residue. Riboflavin precursors with rotational functional groups led to the development of AIE-Cdots. The aggregation of AIE-Cdots was induced selectively for Al3+, amplifying the fluorescence signals owing to the restricted rotation of the side chains on the AIE-Cdot surface. The fluorescence signal of such Al3+-mediated nanoaggregates (Al3+-NAs) was further triggered by the structural fixation of TC at the Al3+ active sites, suggesting the formation of TC-coordinated Al3+-NAs. A linear correlation was observed in the TC concentration range of 0-10 μM with a detection limit of 42 nM. In addition, the strong Al3+ binding affinity of AIE-Cdots produced similar NAs and enhanced fluorescence signals in Al3+-TC mixtures. These AIE-Cdots-based nanoplatforms have a rapid response, good selectivity, and reliable accuracy for detecting TC or aluminum complexes, meeting the requirements for hazardous substance monitoring and removal in environmental applications.

Abstract
To develop a biosensing platform for precise diagnosis and management of thyroid-related diseases, the sensitive and selective recognition and identification of L-thyroxine (T4), a thyroid hormone, remains challenging. We herein introduce T4-imprinted mesoporous organosilica (T4-IMO) for sensitive and specific detection of T4 via the sophisticated engineering of pore surfaces using additives with different polarities. The pore surface of T4-IMO emitting a stable fluorescence signal is simply modified by fixed additives. Additives embedded in the pore surface promote the rebinding response of T4 into the recognized cavities, subsequently sensitizing T4 detection. Notably, T4-IMO containing abundant fluorine elements on the pore surface shows a high affinity toward T4, remarkably boosting the rebinding capacity. In addition to good selectivity to T4, the "turn-off" fluorescent signal exhibits a linear relationship with the logarithm of T4 concentration in a range of 0-500 nM with a detection limit of 0.47 nM in synthetic urine samples. Our findings can establish an insightful strategy for the rational design of molecular-recognition-based sensor systems for the selective and sensitive detection of target analytes.

Abstract
Nanomaterial development has been extensively investigated for several decades to realize sensitive and accurate imaging of tumors in vivo. The manufacturing of nanoparticles with highly efficient tumor targeting and excellent optical properties is still an important research topic. The structure and composition ratio of materials that decisively contribute to the brightness and size of nanoparticles have a great influence on image sensitivity and tumor targeting efficiency. In this study, we developed aggregation-induced emission (AIE) nanoparticles with a widened light absorption window (nanoPMeOCN/BDP) to enable sensitive in vivo tumor imaging. The signal of nanoparticles is enhanced by integrating a high-density AIE polymer (PMeOCN) and light-absorbing fluorescent dye (BDP) in a nanoscopic space. BDP not only improves the light absorption of particles but also enhances the fluorescence signal of particles by effectively transferring absorbed energy to PMeOCN. The physically blended nanoPMeOCN/BDP show strong light absorption and improved sensitivity for the imaging of biological tissues because of their excellent optical performance compared to nanoPMeOCN of similar nanosizes (∼19 nm in size). In vivo imaging results further confirm that nanoPMeOCN/BDP can provide amplified signals with the successful accumulation of tumor tissue through the enhanced permeability and retention effect. We expect that the design strategy of nanoparticles with improved light absorption will provide a simple and general method for improving the accuracy of disease diagnosis.

Abstract
Rationale: Hydrogen peroxide (H2O2) provides an important mechanism for resisting infectious pathogens within the respiratory tract, and accordingly, the in situ analysis of H2O2 generation in real time provides a valuable tool for assessing immune response. Methods: In this study, we applied a chemiluminescent nanoparticle-based real-time imaging approach to noninvasive evaluation of the Duox2-mediated H2O2 generation after viral infection, and assessed its usefulness for analytical purposes in mouse nasal mucosa. The chemiluminescent nanoprobe employed herein (BioNT) possesses appropriate physicochemical properties, such as high sensitivity and selectivity toward H2O2, no background noise, deliverability to the respiratory tract, and capability of multiple injections to a single animal subject for long-term repetitive imaging. Results: The favorable characteristics of BioNT allowed for a longitudinal study with the same mice to noninvasively evaluate the long-term evolution of endogenous H2O2 in the nasal epithelium after infection with influenza A virus (WS/33/H1N1). We found that nasal epithelial cells by themselves respond to viral infection by generating H2O2, and that the in vivo cumulative H2O2 level in the nasal mucosa peaks at day 3 post-infection. Such in vitro and in vivo temporal behaviors of the endogenous H2O2 generation showed a good correlation with those of Duox2 expression after infection. This correlation could be further confirmed with Duox2-deficient subjects (Duox2-knockdown NHNE cells and Duox2-knockout mutant mice) where no H2O2-induced chemiluminescence was detectable even after viral infection. Importantly, upon knock-down of Duox2 expression, the condition of mice caused by viral infection in the upper airway was significantly aggravated, evidencing the involvement of Duox2 in the immune defense. Conclusion: All these results reveal a critical role of Duox2 in the infection-induced H2O2 production and the H2O2-mediated immune response to infection in the respiratory tract, well elucidating the potential of BioNT as a noninvasive tool for fundamental in vivo studies of infectious diseases.

Abstract
OBJECTIVE The aim of this study was to determine whether polymorphisms in solute carrier family 2 and facilitated glucose transporter member 9 (SLC2A9) are associated with susceptibility to gout. METHODS A meta-analysis was conducted on associations between the rs12510549, rs16890979, and rs1014290 polymorphisms of SLC2A9 and gout susceptibility using fixed and random effects models. RESULTS Eleven comparative studies comprising 1,472 patients and 3,269 controls from Caucasian and Asian populations were included in this meta-analysis. The meta-analysis identified a significant negative association between gout and allele 2 (minor) of the rs12510549 polymorphism in the overall population (OR = 0.641, 95 % CI = 0.540-0.761, P = 4.1 × 10-7). Stratification by ethnicity identified a significant negative association between this polymorphism and gout in Caucasians (OR = 0.647, 95 % CI = 0.542-0.771, P = 1.2 × 10-6) but not in Asians (OR = 0.515, 95 % CI = 0.214-1.236, P = 0.137). The meta-analysis showed a significant negative association between gout and allele 2 of the rs16890979 polymorphism in all study subjects (OR = 0.229, 95 % CI = 0.084-0.628, P = 0.004). Stratification by ethnicity identified a significant negative association between this polymorphism and gout in Caucasians (OR = 0.469, 95 % CI = 0.317-0.695, P = 1.6 × 10-6) and in Asians (OR = 0.192, 95 % CI = 0.072-0.513, P = 0.001). A significant negative association was found between allele 2 of the rs1014290 polymorphism and gout susceptibility in Asians (OR = 0.597, 95 % CI = 0.478-0.746, P = 5.4 × 10-6) but not in Caucasians (OR = 0.778, 95 % CI = 0.595-1.043, P = 0.095). CONCLUSIONS This meta-analysis shows that the rs12510549, rs16890979, and rs1014290 polymorphisms of SLC2A9 protect against the development of gout in Caucasians and/or Asians.

Abstract
Objective We aimed to evaluate the relationship between telomere length and systemic lupus erythematosus (SLE). Methods PUBMED and EMBASE databases were searched; meta-analyses were performed comparing telomere length in SLE patients and healthy controls, and on SLE patients in subgroups based on ethnicity, sample type, assay method and data type. Results Eight studies including 472 SLE patients and 365 controls were ultimately selected which showed that telomere length was significantly shorter in the SLE group than in the control group (standardized mean difference (SMD) = -0.835, 95% confidence interval (CI) = -1.291 to -0.380, p = 3.3 × 10-4). Stratification by ethnicity showed significantly shortened telomere length in the SLE group in Caucasian, Asian and mixed populations (SMD = -0.455, 95% CI = -0.763 to -0.147, p = 0.004; SMD = -0.887, 95% CI = -1.261 to -0.513, p = 3.4 × 10-4; SMD = -0.535, 95% CI = -0.923 to -0.147, p = 0.007; respectively). Furthermore, telomere length was significantly shorter in the SLE group than in the control group in whole blood and peripheral blood mononuclear cell groups (SMD = -0.361, 95% CI = -0.553 to -0.169, p = 2.3 × 10-4; SMD = -1.546, 95% CI = -2.583 to -0.510, p = 0.003; respectively); a similar trend was observed in leukocyte groups (SMD = -0.699, 95% CI = -1.511 to -0.114, p = 0.092). Meta-analyses based on assay method or data type revealed similar associations. Conclusions Our meta-analysis demonstrated that telomere length was significantly shorter in patients with SLE, regardless of ethnicity, sample type or assay method evaluated.

Abstract
Sensitive imaging of inflammation with a background-free chemiluminescence (CL) signal has great potential as a clinically relevant way of early diagnosis for various inflammatory diseases. However, to date, its feasibility has been limitedly demonstrated in vivo with locally induced inflammation models by in situ injection of CL probes. To enable systemic disease targeting and imaging by intravenous administration of CL probes, hurdles need to be overcome such as weak CL emission, short glowing duration, or inability of long blood circulation. Here, we report a CL nanoprobe (BioNT) that surmounted such limitations to perform precise identification of inflammation by systemic self-delivery to the pathological tissues. This BioNT probe was engineered by physical nanointegration of multiple kinds of functional molecules into the ultrafine nanoreactor structure (∼15 nm in size) that combines solid-state fluorescence-induced enhanced peroxalate CL and built-in machinery to control the intraparticle kinetics of CL reaction. Upon intravenous injection into a normal mouse, BioNT showed facile blood circulation and generated a self-lighted strong CL torchlight throughout the whole body owing to the tiny colloidal structure with an antifouling surface as well as high CL sensitivity toward endogenous biological hydrogen peroxide (H2O2). In mouse models of local and systemic inflammations, blood-injected BioNT visualized precise locations of inflamed tissues with dual selectivity (selective probe accumulation and selective CL reaction with H2O2 overproduced by inflammation). Even a tumor model that demands a long blood circulation time for targeting (>3 h) could be accurately identified by persistent signaling from the kinetics-tailored BioNT with a 65-fold slowed CL decay rate. We also show that BioNT exhibits no apparent toxicity, thus holding potential for high-contrast diagnostic imaging.

Abstract
OBJECTIVE The aim of this study was to determine whether functional mannose-binding lectin gene (MBL) polymorphisms are associated with the susceptibility to rheumatoid arthritis (RA) or primary Sjögren's syndrome (pSS). METHODS A meta-analysis was conducted to investigate the potential association of RA or pSS with MBL polymorphisms, including the codon 54 (allele B), codon 57 (allele C), and codon 52 (allele D) variants of exon 1, and the - 550 (allele L) and - 221 (allele X) promoter variants. RESULTS A total of 12 comparative studies, including eight RA (1623 patients and 1671 controls) and four pSS (280 patients and 516 controls) studies, were included in the meta-analysis. The meta-analysis revealed no association between the MBL B allele and RA in the overall study population (odds ratio [OR] 0.991, 95 % confidence interval [CI] 0.726-1.355, p = 0.957). However, the meta-analysis showed significant associations between the MBL D, H, and X alleles and RA in the overall population (OR 1.708, 95 % CI 1.077-2.707, p = 0.023; OR 1.936, 95 % CI 1.218-3.078, p = 0.005; OR 1.582, 95 % CI 1.216-2.057, p = 0.001, respectively). An association was found between the MBL B allele and pSS in the overall study population (OR 0.691, 95 % CI 0.541-0.917, p = 0.010). Stratification by ethnicity indicated a trend toward an association between the B allele and pSS in European populations, but no association in Asian populations (OR 0.689, 95 % CI 0.465-1.021, p = 0.063; OR 0.896, 95 % CI 0.311-2.562, p = 0.838, respectively). CONCLUSION This meta-analysis demonstrated an association between the MBL D, L, and X alleles and the risk of RA. It also demonstrated an association between the MBL B allele and the susceptibility to pSS, suggesting a protective role of the MBL B allele against the development of pSS.

Abstract
Extrarenal angiomyolipomas (AMLs) have been reported at various anatomical sites such as the liver, spleen, abdominal wall, retroperitoneum, oral cavity, penis, spermatic cord, skin, and lung but are infrequently described in gynecological regions. However, only a few cases of extrarenal AML in the uterus have been reported. The authors describe a case of uterine AML in a 41-year-old woman with evidence of tuberous sclerosis. Initial diagnosis concluded with myoma based on the interpretation of imaging and other pathological parameters. However, after successful laparoscopic surgical staging, AML was diagnosed. To date, the feasibility of laparoscopic surgical diagnosis and the risks associated with this technique have not been reported. The authors briefly review the implementation of laparoscopic surgical staging to diagnose uterine AML.

Abstract
A simple method of fabricating hemispherical nanostructures on a curved aluminum rod surface was presented. In conventional methods of fabricating nanopatterns on a curved aluminum surface, mechanical or chemical processes have been widely used for the lens technologies. Such processes are not only expensive with long processing times, however, but they also involve local fabrication and are limited in the dimension size. In this paper, a method of fabricating hemispherical nanostructures on a curved aluminum surface is suggested for a functional three-dimensional (3D) master using a low-temperature and high-voltage (LTHV) anodizing method. By reducing the aluminum reaction rate under a low-temperature environment, the reaction current density can be remarkably reduced even though a high voltage was induced. Using the LTHV anodizing method, the hemispherical pattern size can be easily controlled with respect to voltage variations. The sizes of the hemispherical nanopatterns were about 150-300 nm. Using the LTHV anodizing process, hemispherical nanostructures can be obtained on a curved aluminum surface with controllable pattern sizes of 150-300 nm without defects such as burring from Joule's heat, micro-scratches, and cracks. A curved 3D hemispherical nanostructure may be used as a master in the roll-to-roll process.

Abstract
BACKGROUND AND OBJECTIVE Carbamazepine (CBZ) is metabolized mainly by the CYP3A family of enzymes, which includes CYP3A4 and CYP3A5. Several studies have suggested that the CYP3A5*3 genotype influences the pharmacokinetics of CYP3A substrates. The present study aimed to assess the effect of the CYP3A5*3 genotype on serum concentration of CBZ at the steady-state in Korean epileptic patients. METHOD The serum concentrations of CBZ in 35 Korean epileptic patients were measured and their CYP3A5 genotype was determined. Fourteen patients were CYP3A5 expressors (two for CYP3A5*1/*1 and 12 for CYP3A5*1/*3) and 21 patients were CYP3A5 non-expressors (CYP3A5*3/*3). Dose-normalized concentrations (mean +/- SD) of CBZ were 9.9 +/- 3.4 ng/mL/mg for CYP3A5 expressors and 13.1 +/- 4.5 ng/mL/mg for CYP3A5 non-expressors (P = 0.032). The oral clearance of CBZ was significantly higher in CYP3A5 non-expressors than that of CYP3A5 expressors (0.056 +/-0.017 L/h/kg vs. 0.040 +/- 0.014 L/h/kg, P = 0.004). The CYP3A5 genotype affected the CBZ concentrations in Korean epileptic patients and is a factor that may contribute to inter-individual variability in CBZ disposition in epileptic patients.

Abstract
We compared genotyping by restriction fragment length polymorphism (RFLP) analysis of the amplified omp1 gene with serotyping by dot enzyme-linked immunosorbent assay (dot-ELISA) to determine the suitability of RFLP analysis for epidemiologic study. Fifteen prototypes of Chlamydia trachomatis and 30 clinical isolates were used in this study. To serotype with dot-ELISA, chlamydia antigen was spotted onto a series of replicate nitrocellulose membrane patches and reacted with 11 mAbs that distinguish the 15 known serovars of C. trachomatis. For RFLP analysis, the amplified chlamydia omp1 gene was digested with AluI to differentiate serovars A to K and L1 to L3. Serovars of C, H, I, J, and L3 were further typed by RFLP analysis after digestion with HinfI, and a combination of EcoRI and DdeI. PCR-based RFLP could identify serotype of 28 among 30 clinical isolates tested. The remaining two untypical isolates were probably due to double infections or mechanical transferring error. Serotyping of C. trachomatis isolates shows that serovars E, D, F, and H are the most prevalent types found in urogenital samples in Korea. In this study, we show that RFLP analysis of amplified omp1 gene may be useful in genotyping C. trachomatis isolates.

Abstract
BACKGROUND Matrix metalloproteinases (MMPs) have been implicated in the remodelling of extracellular matrix (ECM), including basement membrane. ECM remodelling is associated with pathological processes, including hepatic fibrosis, tumor invasion and metastasis. Tissue inhibitors of metalloproteinase (TIMP)-1 and TIMP-2 were known to inhibit MMP-9 and MMP-2, respectively. In the present study, we examined the expression of TIMP-1 and TIMP-2 in surgical specimen pairs of hepatocellular carcinoma and nontumoral liver and the correlation between their expression and clinicopathological characteristics. METHODS The localization of both transcripts and protein of TIMP-1 and TIMP-2 was studied by using in situ hybridization and immunohistochemistry. RESULTS TIMP-1 and TIMP-2 mRNA transcripts were found in tumor cells, hepatocyte, sinusoidal cells, endothelial cells and stromal cells. Signal intensity of TIMP-1 was stronger than that of TIMP-2. The results of immunohistochemical stainings were concordant with those obtained by in situ hybridization. Expression of TIMP-1 and TIMP-2 was observed in tumorous tissue, in nontumorous tissue and in the portions of the tumors adjacent to the capsules. However, a clear difference in TIMP-1 and TIMP-2 mRNA expression was not observed among the three tissue types. The intensity of TIMP-2 expression was generally weaker than that of TIMP-1, and the intensity of TIMP-1 and TIMP-2 mRNA expression did not correlate with variable clinicopathological characteristics. CONCLUSION TIMPs was expressed in tumor cells and many cell types of the nontumoral liver. Further investigations for TIMPs' unknown functional role are needed.

Abstract
An ideal peptide vaccine should contain both B- and T-cell epitopes. Recognition of antigen by B cells is highly dependent on the three-dimensional conformation of the antigen whereas T cells recognize antigen only after it has been processed to release a peptide fragment which is bound to the major histocompatibility complex (MHC) class II molecule. However, T cells provide 'help' to B cells displaying the same processed, MHC-restricted form of the antigen, demonstrating that the T-cell response to a protein antigen is under genetic control. Thus, strategies for co-inclusion of T cell 'helper' epitopes with the B-cell determinant elicit immune responses that are in most cases genetically restricted to only one or a few alleles of the MHC with limited activity across divergent MHC class II haplotypes. This genetically restricted T cell stimulatory activity of peptides is a serious obstacle and consequently such constructs would be of limited practical value as a vaccine targeted to a majority of an outbred population. In the study described here, we have engineered two peptides to encompass the sequences from the universally immunogenic tetanus toxoid (TT) epitope and the contraceptive vaccine candidate lactate dehydrogenase C4 (LDH-C4). We demonstrate the feasibility of using 'promiscuous' T-cell epitopes colinearly constructed with a defined B-cell epitope to induce high titer antipeptide IgG antibodies specific for native protein antigen LDH-C4 in several inbred strains of mice, outbred mice and rabbits. There appears to be a strong correlation between the capacity for the hybrid peptides to be stimulatory for the corresponding T cells in C57BL/6 (H-2b) and C3H/HeJ (H-2k) mice and their ability to be immunogenic. This correlation, however, appears to break down in H-2d strains of mice since no antibodies were detected in BALB/c and barely detectable levels of antibodies in B10.D2 although activated T cells were detectable. Conversely, high titers of antipeptide antibodies are elicited in some strains (B10.BR (H-2k); C57BL/10 (H-2b) without detectable IL-2 responses. Finally, we show that a determinant which was previously restricted to H-2k can be rendered immunogenic in H-2b with the 'promiscuous' TT epitope. Thus, certain haplotype-restricted immune responses can be bypassed, setting forth the ground work for the design of a universal vaccine by broadening the effective response in a larger number of individuals typical of the genetically diverse outbred human population.
