Abstract
This study aimed to determine whether Glutathione S-transferase M1 (GSTM1), P1 (GSTT1), NFKB1 polymorphisms confer susceptibility to systemic lupus erythematosus (SLE). We performed a meta-analysis on the associations between GSTM1 and GSTT1 null genotypes, and NFKB1 -94 ins/delATTG polymorphisms and SLE. In total, seven studies were considered for this meta-analysis, which comprised 2,119 SLE patients and 3,014 healthy controls. Meta-analysis of the GSTM1 null polymorphism in 869 SLE and 1,544 control subjects revealed an association between SLE and the GSTM1 null genotype (OR = 1.321, 95% CI = 1.103-1.583, p = 0.002). Stratification by ethnicity indicated an association between the GSTM1 null genotype and SLE in Asians (OR = 1.334, 95% CI = 1.096-1.623, p = 0.004). However, meta-analysis of the GSTT1 null polymorphism, comprising 717 SLE and 1,008 control subjects, revealed no association between SLE and the GSTT1 null genotype overall (OR = 0.850, 95% CI = 0.687-1.051, p = 0.113) or in an Asian population (OR = 0.794, 95% CI = 0.594-1.061, p = 0.119). Meta-analysis of the NFKB1 -94 ins/delATTG polymorphism, comprising 1,250 SLE and 1,127 control subjects, revealed an association between SLE and the NFKB1 D allele (OR = 1.127, 95% CI = 1.011-1.257, p = 0.031). Ethnicity-specific meta-analysis revealed an association between the NFKB1 D allele and SLE in Asians (OR = 1.155, 95% CI = 1.026-1.300, p = 0.017). This meta-analysis demonstrates that the functional GSTM1 and NFKB1 polymorphisms are associated with the SLE risk in Asians.

Abstract
OBJECTIVE The purpose of this study was to compare the diagnostic performance of anti-mutated citrullinated vimentin (anti-MCV) and anti-cyclic citrullinated peptide (anti-CCP) antibodies in rheumatoid arthritis (RA). METHODS We searched the Medline, Embase, and Cochrane library databases and performed two meta-analyses on the diagnostic accuracy of anti-MCV and anti-CCP in patients with RA compared to healthy controls. RESULTS We identified 12 studies that included a total of 2003 RA patients and 831 healthy controls for the meta-analysis. The pooled sensitivity and specificity of anti-MCV were 68.6% [95% confidence interval (CI) 66.6-79.7] and 94.2% (95% CI 92.4-96.7) and those of anti-CCP were 61.7% (95% CI 59.5-63.8) and 97.1% (95% CI 96.7-98.1), respectively. Anti-MCV PLR, NLR, and DOR were 12.99 (95% CI 8.013-21.27), 0.297 (95% CI 0.238-0.369), and 47.78 (95% CI 28.59-79.84), and those for anti-CCP were 16.71 (95% CI 11.42-24.47), 0.378 (95% CI 0.325-0.439), and 54.20 (95% CI 31.65-92.82), respectively. The AUC of anti-MCV was 0.886, and its Q* index was 0.817, indicating modest accuracy, while the AUC of anti-CCP was 0.946, and its Q* index was 0.885. The sensitivity of anti-MCV was significantly higher than that of anti-CCP in the diagnosis of RA (difference 0.069, 95% CI 0.039-0.098, p < 0.0001), but the specificity of anti-MCV was lower than that of anti-CCP (difference -0.029, 95% CI -0.051 to -0.006, p = 0.012). The Q* index of anti-MCV was significantly lower than that of anti-CCP (difference -0.068, 95% CI -0.070 to -0.065, p < 0.0001). CONCLUSION Our meta-analysis demonstrates that anti-MCV is more sensitive but less specific, and has lower diagnostic accuracy than anti-CCP in RA, although anti-MCV and anti-CCP showed comparable high PLRs.

Abstract
In the first experiment, the effect of two novel Lactobacillus plantarum strains was studied on the fermentation of spent mushroom substrate (SMS) through 10d of ensiling. Based on lactic acid production and lactic acid bacteria population, L. plantarum KU5 was identified as the best strain for fermentation with a 5-L bag silo. Spent mushroom substrate was ensiled with 0.5% (v/w) L. plantarum KU5 without or with 5% molasses. Silages treated with microbial inoculant and molasses had the lowest pH and the highest fermentative odors. In a second set of experiments similar to the above 5-L silo study, the simultaneous application of L. plantarum KU5 inoculant and molasses to 80-L silos improved fermentability and aerobic stability of SMS silages. For similar treatment using ton-bag silos, aerobic stability decreased and NH3-N content increased dramatically. In conclusion, sawdust-based SMS for animal use was successfully ensiled with L. plantarum KU5 inoculant and molasses.

Abstract
Background The continuing growth of the ethanol industry has generated large amounts of various distillers grains co-products. These are characterized by a wide variation in chemical composition and ruminal degradability. Therefore, their precise formulation in the ruminant diet requires the systematic evaluation of their degradation profiles in the rumen. Methods Three distillers grains plus soluble co-products (DDGS) namely, corn DDGS, high-protein corn DDGS (HP-DDGS), and wheat DDGS, were subjected to an in situ trial to determine the degradation kinetics of the dry matter (DM) and crude protein (CP). Soybean meal (SBM), a feed with highly degradable protein in the rumen, was included as the fourth feed. The four feeds were incubated in duplicate at each time point in the rumen of three ruminally cannulated Hanwoo cattle for 1, 2, 4, 6, 8, 12, 24, and 48 h. Results Wheat DDGS had the highest filterable and soluble A fraction of its DM (37.2 %), but the lowest degradable B (49.5 %; P < 0.001) and an undegradable C fraction (13.3 %; P < 0.001). The filterable and soluble A fraction of CP was greatest with wheat DDGS, intermediate with corn DDGS, and lowest with HP-DDGS and SBM; however, the undegradable C fraction of CP was the greatest with HP-DDGS (41.2 %), intermediate with corn DDGS (2.7 %), and lowest with wheat DDGS and SMB (average 4.3 %). The degradation rate of degradable B fraction (% h−1) was ranked from highest to lowest as follows for 1) DM: SBM (13.3), wheat DDGS (9.1), and corn DDGS and HP-DDGS (average 5.2); 2) CP: SBM (17.6), wheat DDGS (11.6), and corn DDGS and HP-DDGS (average 4.4). The in situ effective degradability of CP, assuming a passage rate of 0.06 h−1, was the highest (P < 0.001) for SBM (73.9 %) and wheat DDGS (71.2 %), intermediate for corn DDGS (42.5 %), and the lowest for HP-DDGS (28.6 %), which suggests that corn DDGS and HP-DDGS are a good source of undegraded intake protein for ruminants. Conclusions This study provided a comparative estimate of ruminal DM and CP degradation characteristics for three DDGS co-products and SBM, which might be useful for their inclusion in the diet according to the ruminally undegraded to degraded intake protein ratio.

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
Objective This study aimed to explore whether TYK2 polymorphisms are associated with susceptibility to autoimmune rheumatic diseases. Methods We conducted a meta-analysis on the association between TYK2 polymorphisms and autoimmune rheumatic diseases. Results Twelve studies with a total of 16,335 patients and 30,065 controls were included in the meta-analysis. Meta-analysis revealed an association between rheumatic diseases and the 2 allele of the TYK2 rs2304256 (OR = 0.885, 95% CI = 0.802–0.978, p = 0.016). Furthermore, stratification by ethnicity identified a significant association between this polymorphism and rheumatic diseases in Caucasians (OR = 0.822, 95% CI = 0.706–0.889, p = 9.5 × 10−7), but not in Asians (OR = 1.127, 95% CI = 0.835–1.522, p = 0.434). Meta-analysis by rheumatic disease type revealed a significant association between the 2 allele of the TYK2 rs2304256 and SLE in Caucasians (OR = 0.737, 95% CI = 0.673–0.808, p < 1.0 × 10−8) but not in Asians (OR = 1.211, 95% CI = 0.813–1.804, p = 0.347). Meta-analysis revealed that the rs12720356 polymorphism was associated with susceptibility to rheumatic diseases in Caucasians (OR = 0.812, 95% CI = 0.661–0.997, p = 0.046) but not in Asians. Interestingly, the rs280519 polymorphism was significantly associated with susceptibility to SLE both in Caucasians and Asians. However, no associations were found between the rs12720270, rs280500, rs280523 and rs8108236 polymorphisms and susceptibility to rheumatic diseases. Conclusions This meta-analysis demonstrates that the TYK2 rs2304256 and rs12720356 polymorphisms are associated with susceptibility to rheumatic diseases, rs2304256 polymorphism is associated with SLE in Caucasians, and rs280519 polymorphism is associated with SLE in Caucasians and Asians.

Abstract
Objective This study aimed to systemically review the evidence regarding the relationship between circulating blood osteopontin (OPN) level and systemic lupus erythematosus (SLE), correlation between serum OPN levels and SLE activity, and association between OPN polymorphisms and SLE susceptibility. Methods We conducted a meta-analysis on the serum/plasma OPN levels in SLE patients and healthy controls, correlation coefficients between the circulating OPN level and SLE Disease Activity Index (SLEDAI) in SLE patients, and the association between OPN polymorphisms and SLE risk. Results Nine studies with 1938 SLE patients and 3037 controls were included. Meta-analysis revealed that, compared with the control group, the OPN level was significantly higher in the SLE group (SMD = 0.965, 95% CI = 0.337-1.393, p = 0.001) and in the SLE group with renal disease (SMD = 2.219, 95% CI = 0.681-3.757, p = 0.005). Meta-analysis of correlation coefficients showed a trend of positive correlation between the circulating OPN level and SLEDAI (correlation coefficient = 0.590, 95% CI = -0.025 to 0.881, p = 0.059). While no association was found between SLE and the OPN 707 T/C and 1083 G/A polymorphisms, a significant association was identified between the OPN 1239 C allele and SLE (OR = 1.192, 95% CI = 1.008-1.410, p = 0.040), and between the OPN 9250 C allele and SLE in Asians (OR = 2.070, 95% CI = 1.570-2.730, p = 2.5 × 10-7). Conclusions Our meta-analysis revealed a significantly higher circulating OPN level in SLE patients, a trend of positive correlation between OPN levels and SLE activity, and a significant association between OPN 1239 C/A and 9250 C/T polymorphisms, and SLE development.

Abstract
The aim of the study is to investigate whether the functional p53 codon 72 polymorphism is associated with susceptibility to SLE and its clinical features. A polymerase chain reaction of genomic DNA-restriction fragment length polymorphism was used to determine genotypes of the p53 codon 72 in 90 SLE patients and 114 healthy controls. Clinical/serological manifestations were analysed in each patient and correlated with the genotypes. The OR of the association of the Pro allele with SLE was 1.70 (95% CI, 1.15-2.53, P = 0.0079) and the OR of the Pro/Pro (a recessive model) was significantly increased (OR = 2.58, 95% CI = 1.24-5.39, P = 0.0093). The Armitage’s trend test indicated a significant dosage effect of the Pro allele for SLE (OR = 1.73, chi-square = 7.08, P = 0.0078). However, there was no significant association of the polymorphism with clinical/serological manifestations studied here. In conclusion, our finding suggests the functional p53 codon 72 polymorphism may be associated with SLE susceptibility, suggesting individuals who carry the Pro allele may have a higher risk to SLE susceptibility than those with the Arg allele. Further studies for replications are needed to confirm that the p53 polymorphism contributes to SLE.

Abstract
OBJECTIVE This study determined whether NLRP3 polymorphisms rs35829419 C/A and rs10754558 C/G were associated with autoimmune and inflammatory diseases. METHODS An association between the NLRP3 rs35829419 C/A and rs10754558 C/G polymorphisms and autoimmune and inflammatory diseases was determined by performing a meta-analysis by using (1) allele contrast, (2) recessive, (3) dominant, and (4) co-dominant models. RESULTS Thirty comparative studies involving 8069 patients and 8824 controls were included in the meta-analysis. No association was observed between autoimmune and inflammatory diseases and NLRP3 rs35829419 C allele (OR = 1.020, 95% CI = 0.804-1.295, p = 0.869). Stratification by ethnicity showed no association between the NLRP3 rs35829419 C allele and autoimmune and inflammatory diseases in European, Latin American, and Polynesian populations. Stratification by disease type showed no association between the NLRP3 rs35829419 C allele and gout, SLE, RA, celiac disease, and Crohn's disease. Moreover, no association was observed between autoimmune and inflammatory diseases and the NLRP3 rs10754558 C allele (OR = 1.057, 95% CI = 0.950-1.177, p = 0.310). However, stratification by ethnicity showed an association between the NLRP3 rs10754558 C allele and autoimmune and inflammatory diseases in the Latin American (OR = 1.399, 95% CI = 1.201-1.630, p = 1.6 × 10-6) but not in European and Asian populations. Further, stratification by disease type showed a significant association of the NLRP3 rs10754558 C allele with SLE (OR = 1.465 95% CI = 1.144-1.875, p = 0.002) but not with gout and celiac disease. The same pattern was observed for the NLRP3 rs10754558 C allele in the recessive model. CONCLUSIONS Our results indicated that the NLRP3 rs10754558 C/G polymorphism was associated with susceptibility to SLE and with autoimmune and inflammatory diseases in Latin American individuals.

Abstract
OBJECTIVE The aim of this study was to determine whether genetic polymorphisms in programmed cell death 1 (PDCD1 or PD1) are associated with susceptibility to rheumatoid arthritis (RA), ankylosing spondylitis (AS), and type 1 diabetes (T1D). METHODS We conducted a meta-analysis to investigate the association between PDCD1 polymorphisms and RA, AS, and T1D in the overall population and in specific ethnic populations. RESULTS Sixteen studies, comprising 13,210 patients and 17,073 controls, were conducted for the meta-analysis including 4 studies on RA, 4 on AS, and 8 on T1D. The meta-analysis showed an association between RA and the 2 alleles of the PD1.3 polymorphism in the overall population [odds ratio (OR) 1.183, 95 % confidence interval (95 % CI) 1.005-1.392, p = 0.043]. However, meta-analysis showed no association between RA and the 2 alleles of the PD1.1 and PD1.5 polymorphisms in the overall population. Meta-analysis identified an association between AS and the 2 alleles of the PD1.5 and PD1.9 polymorphisms in the Asian population (OR 1.251, 95 % CI 1.019-1.535, p = 0.033; OR 1.975, 95 % CI 1.286-3.034, p = 0.002, respectively). The meta-analysis revealed a significant association between T1D and the 2 alleles of the PD1.3 polymorphism in the European population (OR 1.098, 95 % CI 1.029-1.171, p = 0.005). The meta-analysis showed an association between the PD1.5 polymorphism and T1D in Asians (OR 1.332, 95 % CI 1.067-1.663, p = 0.011) and between the PD1.9 polymorphism and T1D in the Asian population (OR 1.363, 95 % CI 1.107-1.679, p = 0.004). CONCLUSION The meta-analysis suggests an association between the PD1.3 polymorphism and RA in the overall population and an association between the PD1.5 and PD1.9 polymorphisms, and AS in the Asian population. Furthermore, the PD1.3 , 5, and 9 polymorphisms were associated with T1D susceptibility in Europeans, or Asians.

Abstract
The purpose of this study was to examine whether the monocyte chemoattractant protein-1 (MCP-1) promoter -2518 A/G polymorphism (rs1024611) is associated with susceptibility to vasculitis, rheumatoid arthritis (RA), or multiple sclerosis (MS). A meta-analysis was conducted on the association between the MCP-1 -2518 A/G polymorphism and vasculitis, RA, and MS. Fourteen studies from 13 articles, including six on vasculitis, five on RA, and three on MS, consisting of 3,038 patients and 3,545 controls were available for the meta-analysis. The meta-analysis revealed no association between the MCP-1 -2518 G allele and vasculitis (odds ratio [OR] = 0.990, 95% confidence interval [CI] = 0.749-1.309, p = 0.943). Stratification by ethnicity indicated no association between the G allele of the MCP-1 -2518 A/G polymorphism and vasculitis in Asians and Caucasians. Meta-analysis by vasculitis type revealed an association between the GG+GA genotype of the MCP-1 -2518 A/G polymorphism and Behçet's disease (BD; OR = 1.349, 95% CI = 1.013-1.796, p = 0.040). However, sensitivity analysis showed that the association was not statistically significant after removing a study that was conducted in China (OR = 1.030, 95% CI = 0.667-1.590, p = 0.895), which indicated that the association was not statistically robust. The meta-analysis revealed no association between the MCP-1 -2518 G allele and RA (OR = 0.986, 95% CI = 0.890-1.093, p = 0.793) or MS (OR = 1.281, 95% CI = 0.802-2.046, p = 0.301). Our meta-analysis demonstrates that the MCP-1 -2518 A/G polymorphism is not associated with susceptibility to vasculitis, RA, or MS.

Abstract
The infraorder Zoarcales (Cottoidei), or eelpouts, includes about 400 species of coldwater fishes concentrated mainly in the North Pacific. To date, the molecular phylogenetic methods in combination with morphological data have significantly contributed to understanding the taxonomic composition of this group and made it possible to confirm/refute validity of some families of obscure origin. In spite of the growing amount of new data on taxonomy and evolution of eelpouts, a consideration of the original and independent data is obviously needed to verify the existing knowledge of this taxon. In this study, which is based on concatenated matrix of Co-1 and Cyt-b mitochondrial genes, as well as relying on the samples from seven families and 45 species of eelpouts, we have reconstructed the phylogeny, which is generally consistent with previous inferences. Despite the resolution of the original data matrix is low, we have demonstrated the monophyletic origin of the families Zoarcidae and Anarhichadidae, as well as Neozoarcidae, previously related to Stichaeidae and recently revised Eulophiidae. The polyphyletic patterns amongst some subfamilies in Stichaeidae have been confirmed, whereas Opisthocentrinae and Pholidae seem to constitute a valid family-level taxon. Our results provide new opportunities with respect to taxonomic relationships in the complex and diverse group of eelpouts , whose part in the tree of life is not covered by recently flourishing multilocus phylogeny of teleost fishes. In light of the data obtained, the necessity of more unified and reproducible approaches to resolve the issues of evolution and taxonomy of such a complex group as Zoarcales becomes more evident.

Abstract
BACKGROUND Literature is lacking on the effects of feeding by-product feed (BF)-based silage on rumen fermentation parameters, nutrient digestion and nitrogen (N) retention in sheep. Therefore, this study was conducted to determine the effect of replacing rye straw with BF-based silage as a roughage source on ruminal parameters, total-tract apparent nutrient digestibility, and N balance in sheep. METHODS The by-product feed silage was composed of spent mushroom substrate (SMS) (45 %), recycled poultry bedding (RPB) (21 %), rye straw (11 %), rice bran (10.8 %), corn taffy residue (10 %), protected fat (1.0 %), bentonite (0.6 %), and mixed microbial additive (0.6 %). Six sheep were assigned randomly to either the control (concentrate mix + rye straw) or a treatment diet (concentrate mix + BF-based silage). RESULTS Compared with the control diet, feeding a BF-based silage diet resulted in similar ruminal characteristics (pH, acetate, propionate, and butyrate concentrations, and acetate: propionate ratio), higher (p < 0.05) ruminal NH3-N, higher (p < 0.05) ether extract digestibility, similar crude protein digestibility, lower (p < 0.05) dry matter, fiber, and crude ash digestibilities, and higher (p < 0.05) N retention (g/d). CONCLUSION The BF-based silage showed similar energy value, higher protein metabolism and utilization, and lower fiber digestion in sheep compared to the control diet containing rye straw.

Abstract
AIMS This study aimed to assess all-cause and cause-specific standardized mortality ratios (SMRs) in patients with systemic lupus erythematosus (SLE). METHODS We surveyed studies examining all-cause and/or cause-specific SMR in patients with SLE compared to the general population using PUBMED, EMBASE and Cochrane databases and manual searches. We performed a meta-analysis of all-cause, sex-specific, ethnicity-specific, and cause-specific SMRs in SLE patients. RESULTS Fifteen reports including 26,101 patients with SLE with 4640 deaths met the inclusion criteria. Compared to the general population, all-cause SMR was significantly increased 2.6-fold in patients with SLE (SMR 2.663, 95% CI 2.090-3.393, p < 1.0 × 10(-8)). Stratification by ethnicity showed that all-cause SMR was 2.721 (95% CI 1.867-3.966, p = 1.9 × 10(-6)) in Caucasians and 2.587 (95% CI 1.475-4.535, p = 0.001) in Asians. Sex-specific meta-analysis revealed that all-cause SMR was 3.141 (95% CI 2.351-4.198, p < 1.0 × 10(-8)) for women and 3.516 (95% CI 2.928-4.221, p < 1.0 × 10(-8)) for men. The risk of mortality was significantly increased for mortality due to renal disease (SMR 4.689, 95% CI 2.357-9.330, p = 1.10 × 10(-5)), cardiovascular disease (CVD) (SMR 2.253, 95% CI 1.304-3.892, p = 0.004), and infection (SMR 4.980, 95% CI 3.876-6.398, p < 1.0 × 10(-8)), although there was no significant increase in SMR for mortality due to cancer (SMR 1.163, 95% CI 0.572-2.363, p = 0.676). CONCLUSIONS Patients with SLE had higher rates of death from all causes, regardless of sex, ethnicity, renal disease, CVD or infection. However, the risk of death due to malignancy was not increased.

Abstract
OBJECTIVE The aim of this study was to determine whether polymorphisms of the Toll-like receptor (TLR) genes are associated with susceptibility to systemic lupus erythematosus (SLE). METHODS The authors conducted a meta-analysis of the relationship between 12 TLR polymorphisms and SLE susceptibility. RESULTS In total, 26 studies that involved 11,984 patients and 14,572 controls were included in the meta-analysis. The meta-analysis showed no association between the two alleles of the rs352140, rs5743836, and rs352139 polymorphisms of TLR9 and SLE, but indicated an association between the two alleles of the rs187084 polymorphism (TLR9) and SLE in the overall population (OR = 0.869, 95% CI = 0.762-0.992, P = 0.038). No association was detected between rs3764880 (TLR8) and SLE; however, our meta-analysis indicated an association between rs3764879 (TLR8) and SLE in Caucasians (OR = 1.414, 95% CI = 1.139-1.756, P = 0.002). An association between rs179008 (TLR7) and SLE was found in the African (OR = 0.430, 95% CI = 0.238-0.775, P = 0.005), but not in the Caucasian population (OR = 1.206, 95% CI = 0.932-1.614, P = 0.145). Furthermore, our meta-analysis indicated a significant association between rs3853839 (TLR7) and SLE in the Asian population (OR = 0.773, 95% CI = 0.735, 0.823, P < 1.0 × 10(-9)). No associations were found between rs5744168 (TLR5), rs4986791 (TLR4), rs4986790 (TLR4), and rs3775291 (TLR3) polymorphisms and SLE susceptibility. CONCLUSIONS Our meta-analysis suggests that TLR7, TLR8, and TLR9 polymorphisms are associated with the development of SLE in Caucasian, Asian, and African populations.

Abstract
It is commonly assumed that creatine kinase (CK) activity in plasma is related to the state of an inflammatory response at 24-48 h, and also it has shown biphasic patterns after a marathon run. No information is available on CK isoenzymes after an ultra-marathon run. The purpose of the present study is to examine the CK isoenzymes after a 200 km ultra-marathon run and during the subsequent recovery. Blood samples were obtained during registration 1 2 h before the 200-km race and during the race at 100 km, 150 km and at the end of 200 km, as well as after a 24 h period of recovery. Thirty-two male ultra-distance runners participated in the study. Serum CPK showed a marked increase throughout the race and 24 h recovery period (p < 0.001). Serum CK during the race occurs mostly in the CK-MM isoform and only minutely in the CK-MB isoform and is unchanged in the CK-BB isoform. High-sensitivity C-reactive protein (hs-CRP), oestradiol, AST and ALT increased significantly from the pre-race value at 100 km and a further increase took place by the end of the 200 km run. The results of our study demonstrate a different release pattern of creatine kinase after an ultra-distance (200 km) run compared to the studies of marathon running and intense eccentric exercise, and changes in several biomarkers, indicative of muscle damage during the race, were much more pronounced during the latter half (100–200 km) of the race. However, the increases in plasma concentration of muscle enzymes may reflect not only structural damage, but also their rate of clearance.

Abstract
This study aimed to explore whether the functional CD24 A57V and TG/del polymorphisms are associated with susceptibility to autoimmune diseases. A meta-analysis was conducted on the associations between the CD24 A57V and TG/del polymorphisms and autoimmune diseases using (1) allele contrast, and (2) the recessive, (3) dominant, and (4) co-dominant models. Twenty-six comparative studies with 7,507 patients and 8,803 controls were included in the meta-analysis. The meta-analysis revealed a significant association between autoimmune disease and the CD24 Val allele (OR = 1.285, 95% CI = 1.177-1.403, p = 1.0 × 10-9). Meta-analysis by autoimmune disease type showed a significant association between the CD24 Val allele and multiple sclerosis (MS) (OR = 1.420, 95% CI = 1.239-1.628, p = 4.7 × 10-8) and systemic lupus erythematous (SLE) (OR = 1.282, 95% CI = 1.081-1.521, p = 0.004), but not Crohn's disease (CD) (OR = 1.003, 95% CI = 0.826-1.218, p = 0.974). Meta-analysis of the CD24 Val/Val genotype showed an association with ulcerative colitis (OR = 1.778, 95% CI = 1.148-2.753, p = 0.010). In addition, meta-analysis by autoimmune disease type revealed a significant association between the CD24 TG-deletion allele and MS (OR = 0.596, 95% CI = 0.415-0.856, p = 0.005) and CD (OR = 1.594, 95% CI = 1.175-2.161, p = 0.003). This meta-analysis indicates that the functional CD24 A57V and TG/del polymorphisms are associated with susceptibility to multiple autoimmune diseases including SLE, MS, UC and CD.

Abstract
This study determined whether interleukin-1 (IL-1) polymorphisms are associated with susceptibility to rheumatoid arthritis (RA). A meta-analysis was conducted on the associations between the IL-1A, IL-1B, and IL-1 receptor antagonist (IL-1RN) polymorphisms and RA. A total of 16 studies involving 4,339 RA cases and 3,885 controls were included in the meta-analysis. Meta-analysis of the IL-1B -511 C/T polymorphism revealed an association between the IL-1B -511 T allele and RA in Caucasians (OR = 0.913, 95% CI = 0.840-0.992, p = 0.031), but not in Asians. Ethnicity-specific meta-analysis indicated an association between the TT+TC genotype of the IL-1B 3953 C/T polymorphism and RA in Caucasians (OR = 1.243, 95% CI = 1.008-1.533, p = 0.042) and in Asians (OR = 2.672, 95% CI = 1.662-4.296, p = 4.9x10-6). No association was between RA susceptibility and the IL-1A -889 C/T, IL-1A +4845 G/T, and IL-1RN +2018 C/T polymorphisms. This meta-analysis suggests the IL-1B -511 C/T polymorphism is associated with susceptibility to RA in Caucasians, and that the IL-1B +3953 C/T polymorphism is associated with susceptibility to RA in Caucasians and Asians.

Abstract
OBJECTIVE The aim of this study was to explore whether the interferon (IFN)-γ +874 T/A polymorphism plays a role in modifying the risk of autoimmune diseases. METHODS A meta-analysis was conducted on the association between the IFN-γ +874 T/A polymorphism and autoimmune diseases. RESULTS Eighteen studies with a total of 2952 patients and 3832 controls were included in the meta-analysis. The meta-analysis revealed no association between autoimmune diseases and the IFN-γ +874 T allele in all study subjects (odds ratio (OR)=1.023, 95% confidence interval (CI) = 0.894-1.171, p = 0.738), but stratification by ethnicity indicated an association between the IFN-γ +874 T allele and autoimmune diseases in Latin American subjects (OR = 0.780, 95% CI = 0.629-0.953, p = 0.015). Meta-analysis also revealed an association between autoimmune diseases and the IFN-γ +874 T/A polymorphism in Caucasian and Middle Eastern subjects under a dominant inheritance model (OR = 0.686, 95% CI = 0.489-0.964, p = 0.003; OR = 1.414, 95% CI = 1.102-1.813, p = 0.006). Meta-analysis by autoimmune disease type indicated an association between ITP and the IFN-γ +874 T allele (OR = 1.753, 95% CI = 1.228-2.503, p = 0.002), but not for vasculitis, vitiligo, and auto-immune thyroid disease. Meta-analysis also showed a significant association between the IFN-γ +874 T/A polymorphism and systemic lupus erythematosus (SLE) under the dominant model (OR = 1.668, 95% CI = 1.114-2.497, p = 0.013). CONCLUSIONS This meta-analysis indicates that the IFN-γ +874 T/A polymorphism may play a significant role in modifying the risk of autoimmune diseases in Caucasian, Latin American, and Middle Eastern subjects, and in particular shows that the IFN-γ +874 T/A polymorphism is associated with increased genetic susceptibility to idiopathic thrombocytopenic purpura and SLE.

Abstract
Diabetes mellitus is closely related to oral-complicated diseases by oxidative stress. This study investigates whether cellular myeloblastosis (c-myb) could protect human dental pulp cells against glucose oxidative stress and regulate autophagy activity for pulp vitality. Diabetes mellitus was induced by streptozotocin in Sprague-Dawley rats, and their pulp tissue in teeth was analyzed in terms of pulp cavity and molecules by hematoxylin and eosin and immunohistochemistry staining. Human dental pulp cells were serially subcultured and treated with glucose oxidase in the presence of elevated glucose to generate glucose oxidative stress. The replication-deficient adenovirus c-myb and small interfering RNA c-myb were introduced for c-myb expression. The pulp tissue from the diabetic rats was structurally different from normal tissue in terms of narrow pulp capacity, reduced c-myb, and dentinogenesis molecules. Glucose oxidase treatment decreased c-myb and dentinogenesis molecules (bone morphogenetic protein 2 and 7, dentin matrix protein 1, and dentin sialophosphoprotein) in human dental pulp cells. However, overexpression of c-myb by adenovirus c-myb increased dentinogenesis, autophagy molecules (autophagy protein 5, microtubule-associated protein 1A/1B-light chain 3, and Beclin-1), and cell survival via p-AMPK/AKT signaling even with glucose oxidative stress. In contrast, the lack of c-myb decreased the above molecules and cell survival by downregulating p-AMPK/AKT signaling. The results indicate that diabetes leads to irreversible damage to dental pulp, which is related to downexpression of autophagy via the p-AMPK/AKT pathway by decline of c-myb. The findings of this study provide a new insight that c-myb could ameliorate autophagy activity and that it is applicable for monitoring complicated diseases of dental pulp. The involvement of c-myb in pulp pathology could serve a therapeutic target in oral-complicated diseases.
