Childhood-Onset Lupus Nephritis in the Childhood Arthritis and Rheumatology Research Alliance Registry: Short-Term Kidney Status and Variation in Care. Arthritis Care Res (Hoboken) 2023; 75:1553-1562. [PMID: 36775844 PMCID: PMC10500561 DOI: 10.1002/acr.25002] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2021] [Revised: 07/14/2022] [Accepted: 08/16/2022] [Indexed: 11/10/2022]
Abstract
OBJECTIVE The goal was to characterize short-term kidney status and describe variation in early care utilization in a multicenter cohort of patients with childhood-onset systemic lupus erythematosus (cSLE) and nephritis. METHODS We analyzed previously collected prospective data from North American patients with cSLE with kidney biopsy-proven nephritis enrolled in the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry from March 2017 through December 2019. We determined the proportion of patients with abnormal kidney status at the most recent registry visit and applied generalized linear mixed models to identify associated factors. We also calculated frequency of medication use, both during induction and ever recorded. RESULTS We identified 222 patients with kidney biopsy-proven nephritis, with 64% class III/IV nephritis on initial biopsy. At the most recent registry visit at median (interquartile range) of 17 (8-29) months from initial kidney biopsy, 58 of 106 patients (55%) with available data had abnormal kidney status. This finding was associated with male sex (odds ratio [OR] 3.88, 95% confidence interval [95% CI] 1.21-12.46) and age at cSLE diagnosis (OR 1.23, 95% CI 1.01-1.49). Patients with class IV nephritis were more likely than class III to receive cyclophosphamide and rituximab during induction. There was substantial variation in mycophenolate, cyclophosphamide, and rituximab ever use patterns across rheumatology centers. CONCLUSION In this cohort with predominately class III/IV nephritis, male sex and older age at cSLE diagnosis were associated with abnormal short-term kidney status. We also observed substantial variation in contemporary medication use for pediatric lupus nephritis between pediatric rheumatology centers. Additional studies are needed to better understand the impact of this variation on long-term kidney outcomes.

Intraarticular steroids as DMARD-sparing agents for juvenile idiopathic arthritis flares: Analysis of the Childhood Arthritis and Rheumatology Research Alliance Registry. Pediatr Rheumatol Online J 2022; 20:107. [PMID: 36434731 PMCID: PMC9701017 DOI: 10.1186/s12969-022-00770-y] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/13/2022] [Accepted: 11/08/2022] [Indexed: 11/26/2022] Open
Abstract
BACKGROUND Children with juvenile idiopathic arthritis (JIA) who achieve a drug free remission often experience a flare of their disease requiring either intraarticular steroids (IAS) or systemic treatment with disease modifying anti-rheumatic drugs (DMARDs). IAS offer an opportunity to recapture disease control and avoid exposure to side effects from systemic immunosuppression. We examined a cohort of patients treated with IAS after drug free remission and report the probability of restarting systemic treatment within 12 months. METHODS We analyzed a cohort of patients from the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry who received IAS for a flare after a period of drug free remission. Historical factors and clinical characteristics and of the patients including data obtained at the time of treatment were analyzed. RESULTS We identified 46 patients who met the inclusion criteria. Of those with follow up data available 49% had restarted systemic treatment 6 months after IAS injection and 70% had restarted systemic treatment at 12 months. The proportion of patients with prior use of a biologic DMARD was the only factor that differed between patients who restarted systemic treatment those who did not, both at 6 months (79% vs 35%, p < 0.01) and 12 months (81% vs 33%, p < 0.05). CONCLUSION While IAS are an option for all patients who flare after drug free remission, it may not prevent the need to restart systemic treatment. Prior use of a biologic DMARD may predict lack of success for IAS. Those who previously received methotrexate only, on the other hand, are excellent candidates for IAS.

Social determinants of health influence disease activity and functional disability in Polyarticular Juvenile Idiopathic Arthritis. Pediatr Rheumatol Online J 2022; 20:18. [PMID: 35255941 PMCID: PMC8903717 DOI: 10.1186/s12969-022-00676-9] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/30/2021] [Accepted: 02/07/2022] [Indexed: 11/23/2022] Open
Abstract
BACKGROUND Social determinants of health (SDH) greatly influence outcomes during the first year of treatment in rheumatoid arthritis, a disease similar to polyarticular juvenile idiopathic arthritis (pJIA). We investigated the correlation of community poverty level and other SDH with the persistence of moderate to severe disease activity and functional disability over the first year of treatment in pJIA patients enrolled in the Childhood Arthritis and Rheumatology Research Alliance Registry. METHODS In this cohort study, unadjusted and adjusted generalized linear mixed effects models analyzed the effect of community poverty and other SDH on disease activity, using the clinical Juvenile Arthritis Disease Activity Score-10, and disability, using the Child Health Assessment Questionnaire, measured at baseline, 6, and 12 months. RESULTS One thousand six hundred eighty-four patients were identified. High community poverty (≥20% living below the federal poverty level) was associated with increased odds of functional disability (OR 1.82, 95% CI 1.28-2.60) but was not statistically significant after adjustment (aOR 1.23, 95% CI 0.81-1.86) and was not associated with increased disease activity. Non-white race/ethnicity was associated with higher disease activity (aOR 2.48, 95% CI: 1.41-4.36). Lower self-reported household income was associated with higher disease activity and persistent functional disability. Public insurance (aOR 1.56, 95% CI 1.06-2.29) and low family education (aOR 1.89, 95% CI 1.14-3.12) was associated with persistent functional disability. CONCLUSION High community poverty level was associated with persistent functional disability in unadjusted analysis but not with persistent moderate to high disease activity. Race/ethnicity and other SDH were associated with persistent disease activity and functional disability.

Reproducibility of liver R2* quantification for liver iron quantification from cardiac R2* acquisitions. Abdom Radiol (NY) 2021; 46:4200-4209. [PMID: 33982186 PMCID: PMC8346410 DOI: 10.1007/s00261-021-03099-4] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2020] [Revised: 04/14/2021] [Accepted: 04/21/2021] [Indexed: 01/19/2023]
Abstract
OBJECTIVES To evaluate the reproducibility of liver R2* measurements between a 2D cardiac ECG-gated and a 3D breath-hold liver CSE-MRI acquisition for liver iron quantification. METHODS A total of 54 1.5 T MRI exams from 51 subjects (18 women, 36 men, age 35.2 ± 21.8) were included. These included two sub-studies with 23 clinical MRI exams from 19 patients identified retrospectively, 24 participants with known or suspected iron overload, and 7 healthy volunteers acquired prospectively. The 2D cardiac and the 3D liver R2* maps were acquired in the same exam. Either acquisitions were reconstructed using a complex R2* algorithm that accounts for the presence of fat and residual phase errors due to eddy currents. Data were analyzed using colocalized ROIs in the liver. RESULTS Linear regression analysis demonstrated high Pearson's correlation and Lin's concordance coefficient for the overall study and both sub-studies. Bland-Altman analysis also showed good agreement, except for a slight increase of the mean R2* value above ~ 400 s-1. The Kolmogorow-Smirnow test revealed a non-normal distribution for (R2* 3D-R2* 2D) values from 0 to 600 s-1 in contrast to the 0-200 s-1 and 0-400 s-1 subpopulations. Linear regression analysis showed no relevant differences other than the intercept, likely due to only 7 measurements above 400 s-1. CONCLUSIONS The results demonstrate that R2*-measurements in the liver are feasible using 2D cardiac R2* maps compared to 3D liver R2* maps as the reference. Liver R2* may be underestimated for R2* > 400 s-1 using the 2D cardiac R2* mapping method.

Abstract
OBJECTIVE To prepare the human bone morphogenetic protein-2(hBMP-2)/human insulin-like growth factor-1(hIGF-1)coating titanium(Ti)and assess its performance as a dental implant material. METHODS hBMP-2 and hIGF-1 were coated to the smooth surface of a Ti plate, and its efficacy for promoting bone formation and bone integration was compared with a pristine Ti plate.The surface characteristics of the metal samples were evaluated using scanning electron microscope (SEM) and by contact angle measurement.MG63 cells were seeded on the surface of the Ti plates, and MTT assay and alizarin red staining was used to examine the cell proliferation and formation of calcified nodules, respectively.Alkaline phosphatase (ALP)secretion of the cells was examined with ELISA, and cellular expressions of osteocalcin and osteopontin were detected with Western blotting for assessing osteogenesis. RESULTS SEM examination showed that the surface of Ti with hBMP-2 and hIGF-1 coating presented with a radial pattern resembling snowflakes.The contact angles of non-coated Ti, hBMP-2-coated Ti, hIGF-1-coated, and hBMP-2/-hIGF-1-coated Ti samples were 83.2°, 54°, 56° and 54°, respectively.Compared with the non-coated Ti plate, the surface-modified Ti samples showed a significantly smaller contact angle (P=0.032, 0.029, and 0.028), indicating a good hydrophilicity of the samples.MTT assay showed that MG63 cells grew well on the surface of the coated Ti plates.The hBMP-2/IGF-1 coating significantly induced cellular secretion of ALP(P=0.021, 0.014)and obviously promoted osteogenesis of MG63 cells (P < 0.05).Western blotting results showed that hBMP-2/IGF-1 coating significantly enhanced the expressions of osteocalcin and osteopontin in the seeded cells (P < 0.05). CONCLUSION hBMP-2 and hIGF-1 coating of Ti material can promote osteogenesis of the cells seeded on its surface to improve the performance of such Ti material as dental implants.

Abstract
We present a method for using dynamic light scattering in the single-scattering limit to measure the viscoelastic moduli of soft materials. This microrheology technique only requires a small sample volume of 12 μL to measure up to six decades in time of rheological behavior. We demonstrate the use of dynamic light scattering microrheology (DLSμR) on a variety of soft materials, including dilute polymer solutions, covalently-crosslinked polymer gels, and active, biological fluids. In this work, we detail the procedure for applying the technique to new materials and discuss the critical considerations for implementing the technique, including a custom analysis script for analyzing data output. We focus on the advantages of applying DLSμR to biologically relevant materials: breast cancer cells encapsulated in a collagen gel and cystic fibrosis sputum. DLSμR is an easy, efficient, and economical rheological technique that can guide the design of new polymeric materials and facilitate the understanding of the underlying physics governing behavior of naturally derived materials.

Abstract
The present study aims to investigate the protective effects of Dendrobine and its underlying mechanisms on liver injury induced by isoniazid (INH) and rifampicin (RIF). A mouse model of liver injury was induced by intragastrically administration of 100 mg/kg INH and 100 mg/kg RIF for 14 days. The mice were intragastrically administrated with Dendrobine (50, 100, and 200 mg/kg) before the administration of INH and RIF. Serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were determined. Oxidative stress markers including glutathione, superoxide dismutase, and malondialdehyde in the liver were measured and liver histopathological examinations were performed. Quantitative reverse transcription polymerase chain reaction (qRT-PCR) and Western blot were applied to determine the mRNA and protein expressions, respectively. Luciferase reporter assay was used to evaluate the interactions between miR-295-5p and CYP1A2. Dendrobine significantly decreased serum ALT and AST and inhibited the liver index and ameliorated the liver histological changes induced by INH and RIF. Besides, Dendrobine also regulated oxidative stress status in the liver by the regulation of CYP1A2. Moreover, mmu-miR-295-5p was identified to target CYP1A2 and to regulate the expression of CYP1A2. In summary, Dendrobine ameliorated INH and RIF induced mouse liver injury by miR-295-5p-mediated CYP1A2 expression.

Abstract
OBJECTIVE Recent studies have revealed that long noncoding RNAs (lncRNAs) play important roles in the progression of tumorigenesis. Oral squamous cell carcinoma is a disease widely widespread all over the world. The aim of this study was to identify how lncRNA INHBA-AS1 functions in the progression of OSCC. PATIENTS AND METHODS LncRNA INHBA-AS1 expression in both OSCC cells and 48 paired tissue samples was detected by Real Time-quantitative Polymerase Chain Reaction (RT-qPCR). The function of INHBA-AS1 was identified by the transwell assay, wound healing assay, and proliferation assay in vitro. Meanwhile, the role of INHBA-AS1 was investigated through tumor formation assay in vivo. Furthermore, the underlying mechanism was explored by the luciferase assays and RNA immunoprecipitation assay (RIP). RESULTS INHBA-AS1 was highly expressed in OSCC tissues when compared with adjacent tissue samples. The proliferation, invasion, and migration of OSCC cells were significantly inhibited after the knockdown of INHBA-AS1 in vitro. Meanwhile, the knockdown of INHBA-AS1 remarkably inhibited tumor growth and metastasis in vivo. Besides, miR-143-3p was down-regulated after the knockdown of INHBA-AS1 in vitro. The expression of miR-143-3p was negatively correlated with the expression of INHBA-AS1 in OSCC tissues. In addition, miR-143-3p was directly targeted by INHBA-AS1. CONCLUSIONS The knockdown of INHBA-AS1 repressed cell migration, invasion, and proliferation in OSCC by sponging miR-143-3p, which might offer a new therapeutic intervention for OSCC patients.

Abstract
With the increasing prevalence of obesity in women of reproductive age there is a need to understand the ramifications of this on offspring. The purpose of this study is to investigate the programming effects of maternal obesity during preconception and the preconception/gestational period on adiposity and adipose tissue inflammation in offspring using an animal model. Adult female C57Bl/6J mice were assigned either normal diet, high fat diet (HFD) prior to pregnancy, or HFD prior to and through pregnancy. Some offspring were maintained on normal diet while others started HFD later in life. Offspring were assessed for body composition and metabolic responses. Lipid storing tissues were evaluated for expansion and inflammation. Male offspring from the preconception group had the greatest weight gain, most subcutaneous adipose tissue, and largest liver mass when introduced to postnatal HFD. Male offspring of the preconception/gestation group had worsened glucose tolerance and an increase in resident (CD11c−) adipose tissue macrophages (ATMs) when exposed to postnatal HFD. Female offspring had no significant difference in any parameter between the diet treatment groups. In conclusion, this study demonstrates that prenatal and pregnancy windows have independent programming effects on offspring. Preconception exposure affects body composition and adiposity while gestation exposure affects metabolism and tissue immune cell phenotypes.

Abstract
To analyze the correlation of the level of serum heat shock protein 90α (HSP-90α) in healthy and breast cancer patients, studying the evaluation of neoadjuvant efficacy and Clinical value of relapse monitoring.
A total of 102 healthy women were selected, 51 cases of breast benign tumor ,423 cases of female breast cancer all diagnosed by pathology,other system malignancies 62 cases. ALL the serum samples HSP-90αwas detected by double-antibody ELISA. The CEA, CA125,CA15-3 were detected by Roche Cobas ECL analyzer. The ROC curve was used to analyze the effectiveness of serum HSP-90α in the early diagnosis of breast cancer. The dynamic changes of HSP-90αlevel before and after treatment were analyzed by Wilcoxon's rank test. Moreover, we also combine the HSP-90αwith CEA,CA125,CA15-3 to evaluate the clinical value of monitoring the recurrence of breast cancer.
The levels of serum HSP-90α (123.49 ± 105.1ng / ml) in breast cancer patients wes significantly higher than that in healthy controls (40.33 ± 14.18ng / ml), benign breast disease (80.15 ± 103.09ng / ml) and carcinoma in situ (34.7 ± (114.31 ± 146.91ng / ml),the difference was statistically significant (P <0.001). .According to the ROC curve analysis of patients and healthy subjects, the cut-offvalue was set as HSP-90=59.7ng / ml, AUC=0.834, the sensitivity and specificity to diagnosis of breast cancer was 90.3% and 78.6% respectively ,the negative predictive value was 93.88%.The levels of serum HSP-90α was significantly decreased (P <0.05) after tumor resection and the patients who obtain PR from the neoadjuvant chemotherapy. When HSP-90=43.22ng / ml was set as the cut-off value for diagnosing the recurrence of breast cancer, AUC=0.877,the sensitivity and specificity were 95.7% and 74.5% respectively, and the negative predictive value was 96.2%. At the same time, we find that combined HSP-90α with CEA, CA125, CA15-3 can improve the accuracy of recurrence prediction.
Serum HSP-90α has a good clinical diagnostic value in breast cancer and can be used as a recurrence monitoring tool for post-adjuvant treatment patients.

Abstract
Abstract
Background: Metastatic breast cancer remains an incurable disease, and clinical benefit and progression-free survival are the main end points in advanced setting. Targeted therapies have shown promising potentials in HER2-positive breast cancer, but with uncertain effects in HER2-negative breast cancer, especially when the disease is progressing rapidly. The regimen of antiangiogenic therapy in combination with chemotherapy had been studied for years and gained improved efficacy. Apatinib is an oral, highly potent tyrosine kinase inhibitor targeting vascular endothelial growth factor receptor 2. PhaseIIclinical trials of Apatinib single agent had presented objective response and manageable toxicity in heavily pretreated, metastatic breast cancer. Oral vinorelbine represents a good choice for its toxicity and activity in anthracycline and taxane-pretreated breast cancer patients. This all-oral study aims to investigate the efficacy and safety of the oral vinorelbine-apatinib combination in pre-treated metastatic breast cancer. Methods: This study enrolled patients with HER2-negative advanced breast cancer, pretreated with anthracycline/taxanes, and who failed in the metastatic setting at least one prior chemotherapy or endocrine therapy when hormone receptor is positive. Patients were treated with apatinib 500mg/425mg daily plus oral vinorelbine 60mg/m2 day1,8,15 every 3 weeks/cycle. Patients eligible were evaluated by CT or MRI scan at baseline and every 2 cycles (6 weeks) there after until disease progressed. The primary endpoint wasPFS. The secondary endpoints were objective response rate, clinical benefit rate, OS, and safety. Results: 40 patients were enrolled with a median age of 55 (30-70) years. First 17 patients started apatinib at the dose of 500mg/day. Considering safety issues, a lower dose of apatinib 425mg/day was subsequently started as the initial dose after these 17 patients recruited. 26(65.0%) patients experienced treatment delay and 20(50.0%) patients experienced dose modification during treatment. Median follow-up time was 10.3 months. Of all 40 patients, median PFS was 5.4 months (95% CI, 3.4m–7.3m). Median OS was not reached. 32 patients were eligible for efficacy analysis. ORR was 15.6% (5/32). CBR was 46.9% (15/32). Patients with triple-negative breast cancer or who received combined therapy as second line treatment gained better ORR and longer median PFS. The most common adverse events of all grades included gastrointestinal reaction (70.0%), myelosuppression (67.5%), hypertension(62.5%), pain(60.0%), malaise(52.5%), anorexia(50.0%), elevated transaminase(47.5%), hand-foot reaction (47.5%), proteinuria (37.5%), and elevated bilirubin(32.5%). Proteinuria, treatment delay, and ECOG performance status were independent predictive factors for PFS.Conclusions: The all-oral therapy of antiangiogenic tyrosine kinase inhibitor apatinib plus vinorelbine presented objective efficacy in advanced HER2-negative breast cancer who failed from first-line therapy, with acceptable and manageable toxicity.

Abstract
Biological systems are equipped with a diverse repertoire of proteins that regulate DNA topology with precision that is beyond the reach of conventional polymer chemistry. Here, we harness the unique properties of topoisomerases to synthesize Olympic hydrogels formed by topologically interlinked DNA rings. Using dynamic light scattering microrheology to probe the viscoelasticity of DNA topological networks, we show that topoisomerase II enables the facile preparation of active, adenosine triphosphate-driven Olympic hydrogels that can be switched between liquid and solid states on demand. Our results provide a versatile system for engineering switchable topological materials that may be broadly leveraged to model the impact of topological constraints and active dynamics in the physics of chromosomes and other polymeric materials.

Abstract
The development of experimental techniques capable of probing the viscoelasticity of soft materials over a broad range of time scales is essential to uncovering the physics that governs their behavior. In this work, we develop a microrheology technique that requires only 12 μL of sample and is capable of resolving dynamic behavior ranging in time scales from 10-6 to 10 s. Our approach, based on dynamic light scattering in the single-scattering limit, enables the study of polymer gels and other soft materials over a vastly larger hierarchy of time scales than macrorheology measurements. Our technique captures the viscoelastic modulus of polymer hydrogels with a broad range of stiffnesses from 10 to 104 Pa. We harness these capabilities to capture hierarchical molecular relaxations in DNA and to study the rheology of precious biological materials that are impractical for macrorheology measurements, including decellularized extracellular matrices and intestinal mucus. The use of a commercially available benchtop setup that is already available to a variety of soft matter researchers renders microrheology measurements accessible to a broader range of users than existing techniques, with the potential to reveal the physics that underlies complex polymer hydrogels and biological materials.

Abstract
Originally, the middle longitudinal fascicle (MdLF) was defined as a long association fiber tract connecting the superior temporal gyrus and temporal pole with the angular gyrus. More recently its description has been expanded to include all long postrolandic cortico-cortical association connections of the superior temporal gyrus and dorsal temporal pole with the parietal and occipital lobes. Despite its location and size, which makes MdLF one of the most prominent cerebral association fiber tracts, its discovery in humans is recent. Given the absence of a gold standard in humans for this fiber tract, its precise and complete connectivity remains to be determined with certainty. In this study using high angular resolution diffusion MRI (HARDI), we delineated for the first time, six major fiber connections of the human MdLF, four of which are temporo-parietal and two temporo-occipital, by examining morphology, topography, cortical connections, biophysical measures, volume and length in seventy brains. Considering the cortical affiliations of the different connections of MdLF we suggested that this fiber tract may be related to language, attention and integrative higher level visual and auditory processing associated functions. Furthermore, given the extensive connectivity provided to superior temporal gyrus and temporal pole with the parietal and occipital lobes, MdLF may be involved in several neurological and psychiatric conditions such as primary progressive aphasia and other aphasic syndromes, some forms of behavioral variant of frontotemporal dementia, atypical forms of Alzheimer's disease, corticobasal degeneration, schizophrenia as well as attention-deficit/hyperactivity Disorder and neglect disorders.

Abstract
BACKGROUND AND PURPOSE MR imaging can be used to measure structural changes in the brains of individuals with multiple sclerosis and is essential for diagnosis, longitudinal monitoring, and therapy evaluation. The North American Imaging in Multiple Sclerosis Cooperative steering committee developed a uniform high-resolution 3T MR imaging protocol relevant to the quantification of cerebral lesions and atrophy and implemented it at 7 sites across the United States. To assess intersite variability in scan data, we imaged a volunteer with relapsing-remitting MS with a scan-rescan at each site. MATERIALS AND METHODS All imaging was acquired on Siemens scanners (4 Skyra, 2 Tim Trio, and 1 Verio). Expert segmentations were manually obtained for T1-hypointense and T2 (FLAIR) hyperintense lesions. Several automated lesion-detection and whole-brain, cortical, and deep gray matter volumetric pipelines were applied. Statistical analyses were conducted to assess variability across sites, as well as systematic biases in the volumetric measurements that were site-related. RESULTS Systematic biases due to site differences in expert-traced lesion measurements were significant (P < .01 for both T1 and T2 lesion volumes), with site explaining >90% of the variation (range, 13.0-16.4 mL in T1 and 15.9-20.1 mL in T2) in lesion volumes. Site also explained >80% of the variation in most automated volumetric measurements. Output measures clustered according to scanner models, with similar results from the Skyra versus the other 2 units. CONCLUSIONS Even in multicenter studies with consistent scanner field strength and manufacturer after protocol harmonization, systematic differences can lead to severe biases in volumetric analyses.

Identification and measurement of staphylococcal enterotoxin M from Staphylococcus aureus isolate associated with staphylococcal food poisoning. Lett Appl Microbiol 2017; 65:27-34.

Abstract
Staphylococcus aureus produces a wide variety of staphylococcal enterotoxins (SEs, SEA to SEX), which are responsible for staphylococcal food poisoning. This study is aimed to establish a system to detect staphylococcal enterotoxin M (SEM) protein in food matrixes. In the present study, sem gene was characterized in a S. aureus isolate H4 associated with food poisoning. The amino acid sequence of the deduced SEM protein was same as that of previously identified SEM from S. aureus 04-02981. Subsequently, mature SEM protein was expressed in Escherichia coli BL21 (DE3) cells and purified with a Ni-NTA spin column. The polyclonal and monoclonal antibody against it were prepared. Using these antibodies, a highly sensitive, specific sandwich enzyme-linked immunosorbent assay (ELISA) system was developed capable of detecting SEM in milk, meat and rice. Cross-reactivity with SEB, SEI and SEK in this method was insignificant. Quantification of SEM secretion in vitro using this novel capture ELISA revealed that SEM was mainly secreted during the transition from the exponential to the stationary phase. Furthermore, sem gene and SEM protein production were screened by PCR and the developed ELISA system. The results indicated that there were two SEM+ strains of 19 S. aureus isolates originating in cold dishes and humans suffering from food poisoning. The investigations make it possible to assess SEM in food hygiene supervision in near future. SIGNIFICANCE AND IMPACT OF THE STUDY Staphylococcal enterotoxins (SE) are the main causative agents of staphylococcal food poisoning. Unlike classical SEs (SEA to SEE), the relationship between newly identified SEs (SEG to SEX) and staphylococcal food poisoning has not been clearly elucidated. Recently, mild emetic potential of staphylococcal enterotoxin M (SEM) has been demonstrated, which indicated that SEM might be associated with food poisoning. However, there is currently no commercial enzyme-linked immunosorbent assay (ELISA) kit available for immunological detection of it. Therefore, we developed a highly sensitive, specific sandwich ELISA system and assayed SEM in food matrixes. This assay facilitates the study of SEM expression in vitro and in vivo. In addition, the investigations would be helpful in addressing the relative incidence of SEM+ strains in near future.

Abstract
AIMS Staphylococcus aureus (Staph. aureus) produces a wide variety of staphylococcal enterotoxins (SEs) and staphylococcal enterotoxin-like (SEl) proteins, which are the most causative agents of staphylococcal food poisoning. In contrast to classical SEs (SEA to SEE), the relationship between the novel SEs/SEls (SEG to SElX) and staphylococcal food poisoning is not elucidated. This study is aimed to establish a system to detect staphylococcal enterotoxin-like protein I (SElI) for analysis of staphylococcal food poisoning. METHODS AND RESULTS SElI was characterized in a Staph. aureus clinical isolate associated with food poisoning; there was an amino acid substitution Thr145Ala compared to previously identified SEI from Staph. aureus 04-02981. Subsequently, SElI was expressed, purified, and the poly- and monoclonal antibodies against it were prepared. Using these antibodies, a highly sensitive sandwich enzyme-linked immunosorbent assay (ELISA) that specifically detected and measured SElI secretion from the Staph. aureus clinical isolate in LB medium, milk and bloodstream was developed. CONCLUSIONS The ELISA system has been successfully applied for analysing SElI secretion in vivo and in vitro. SIGNIFICANCE AND IMPACT OF THE STUDY The highly sensitive ELISA should make it attractive for quantifying SElI in food hygiene supervision and clinical diagnosis in near future.
