    ABSTRACT: The aim of this study was to investigate the mRNA expression levels of suppressor of cytokine signaling 1 (SOCS1) in patients with systemic lupus erythematosus (SLE) compared with healthy controls. The associations of systemic lupus erythematosus disease activity index scores and clinical features of SLE with the expression levels of SOCS1 mRNA were also evaluated. Real-time quantitative reverse transcription-polymerase chain reaction was applied to detect the mRNA expression levels of SOCS1 in peripheral blood mononuclear cells from 34 patients with SLE and 34 healthy controls. The mRNA expression level of SOCS1 was significantly decreased in SLE patients in comparison with healthy controls (Z = -4.207, P < 0.001). Lower SOCS1 mRNA expression was detected in active SLE patients when compared with inactive ones (Z = -2.428, P = 0.015). There was no significant difference found for the SOCS1 mRNA levels between SLE patients with nephritis and those without (Z = -0.642, P = 0.521). The presence of photosensitivity, proteinuria, positive antinuclear antibody, and C4 decline were associated with SOCS1 mRNA levels in SLE patients (all P < 0.05). Furthermore, the SOCS1 mRNA expression was negatively correlated with disease activity (r s = -0.372, P = 0.030). Our results suggest that the dysregulation of SOCS1 might be associated with the pathogenesis of SLE.

    ABSTRACT: Africa is a continent full of untapped natural resources ranging from biodiversity to vast water bodies but faced with food and energy crises. Prices of fuel are also escalating. With researchers and experts scrambling for the solution, biodiesel from vegetable oil will receive more attention. But the edible feedstock as the obvious cheapest choice will not be sustainable enough for the increasing energy and food demand; hence, there is a need for guaranteed feedstock. This study was therefore undertaken to explore feedstock that would not be suitable for food but useful for biodiesel in Africa. Among the highlight areas of the study include current energy situation in Africa, technologies of biodiesel production, current state of biodiesel in Africa, driving forces for increase in biodiesel production, current existing problems of biodiesel commercialization, potential benefits of biodiesel processes, need for non-edible oil plants, potential non-edible biodiesel feedstock, biology, distribution and chemistry of the selected non-edible oil plants. The study also throws light on the implication of biodiesel on the environment and the outlook. From the study, the use of non-edible oils can be guaranteed as sustainable feedstock for biodiesel since most of the non-edible plants can be grown on wastelands to reclaim them, not compete with food crops for limited lands, are relatively cheap, available and offer similar or even higher yields of biodiesel and fuel properties as the edibles. Developing biodiesel industry in Africa can help curb the high rate of unemployment through job creation as well as increase in income level of the rural populace. Weaning African economies from oil import dependencies could also be an economic achievement. It can be deduced from the study that there are promising non-edible oil resources in the system for biodiesel industrialization in Africa.

    ABSTRACT: Abstract Objectives: Previous published data indicated that interleukin-21 (IL-21) gene polymorphisms were shown to associate with multiple autoimmune diseases (ADs), but the results remain inconclusive. The aim of this study was to perform a meta-analysis to assess the overall association between IL-21 gene polymorphisms (rs907715, rs2221903) and multiple ADs. Methods: All eligible case-control studies were searched in the PubMed and Embase database. A meta-analysis was conducted on the association between the IL-21 gene variants and ADs using: (1) allelic contrast, (2) homozygote contrast, (3) the recessive model, and (4) the dominant model. Results: A total of 12 relevant studies including 10 535 cases and 19 356 controls were enrolled in this meta-analysis. A significant association between IL-21 rs907715 gene polymorphism and AD was found under the allelic (OR: 1.102, 95% CI: 1.057-1.149, p = 0.000), homozygous (OR: 1.220, 95% CI: 1.089-1.368, p = 0.001), dominant (OR: 1.160, 95% CI: 1.027-1.309, p = 0.017), and recessive genetic model (OR: 1.119, 95% CI: 1.055-1.187, p = 0.000) among Caucasian populations. However, there was no significant association between IL-21 rs2221903 polymorphism and AD in different genetic models. Conclusions: Data from the present study suggest that the IL-21 rs907715 polymorphism might be associated with multiple ADs susceptibility in Caucasians. Especially, the allele G of intronic rs907715 in IL-21 confers increased risk of ADs.

    ABSTRACT: The aim of this study was to determine the risk factors for avascular necrosis (AVN) in patients with systemic lupus erythematosus (SLE). Four electronic databases (PubMed, EMBASE, Ovid, and Science Direct) were searched for. The search was performed to identify the articles as to SLE with AVN before September 2013. The clinical and laboratory data were extracted, and a meta-analysis was performed to identify the risk factors for AVN in patients with SLE. Publication bias was assessed with funnel plot and Egger's test. A total of 995 papers were found from the four databases; 16 studies were finally included. Pooled analysis showed the following result. The result showed that arthritis (odds ratio (OR) = 2.448, 95 % confidence interval (CI) = 1.617-3.707), cushingoid (OR = 3.890, 95 % CI = 1.591-9.510), gastrointestinal involvement (OR = 2.054, 95 % CI = 1.283-3.290), hypertension (OR = 1.482, 95 % CI = 1.093-2.008), oral ulcers (OR = 1.877, 95 % CI = 1.182-2.979), pleuritis (OR = 2.302, 95 % CI = 1.325-4.001), renal disease (OR = 1.475, 95 % CI = 1.124-1.936), and vasculitis (OR = 2.591, 95 % CI = 1.358-4.944) were relevant with AVN in SLE patients. Cytotoxic drug (OR = 1.834, 95 % CI = 1.065-3.156, P = 0.029), the total cumulative dose (Standard Mean Difference (SMD) = 1.104, 95 % CI = 0.118-2.090, P = 0.028), maximum daily dose (SMD = 0.484, 95 % CI = 0.288-0.678, P < 0.001), and mean daily dose (SMD = 1.305, 95 % CI = 0.061-2.549, P = 0.040) were significantly higher in AVN group. There were no significantly laboratory features that appeared in this pooled analysis. We conclude that arthritic, cushingoid, gastrointestinal involvement, hypertension, oral ulcers, pleuritis, renal disease, vasculitis, cytotoxic drug, and steroid treatment may contribute to AVN in SLE patients.

    ABSTRACT: Abstract The purpose of this study was to evaluate whether a single-nucleotide polymorphism (SNP), rs2243188 of interleukin-19 (IL-19), show significant evidence for association with SLE in a Chinese population. A total of 545 SLE patients and 613 healthy controls were collected in the present study. The genotyping of IL-19 rs2243188 polymorphism was detected by TaqMan allele discrimination assay on the 7300 real time polymorphism chain reaction system. The minor C allele of rs2243188, relative to the major A allele, appeared to have a significantly lower frequency in SLE patients (31.0%) as compared with controls (35.5%) (χ(2) = 5.19, p = 0.023). We also discovered a statistical significance in the dominant model (CC + CA versus AA: OR = 0.755, 95% CI = 0.598-0.953, p = 0.018). However, no significant difference in genotype distribution was found between SLE patients and controls (p = 0.056). Furthermore, an increased frequency of CC genotype were also detected in lupus nephritis (LN) groups as compared with non-LN groups (p = 0.024). Besides, the individuals with CC genotype had a 2.201-fold higher risk for the susceptibility to LN than those A allele carriers (AA + CA) (p = 0.006). Unfortunately, the analyses on the relationship of IL-19 rs2243188 with several clinical manifestations of SLE failed to find any significant results. In conclusion, our observations suggested the minor C allele of SNP rs2243188 might be a protective factor for SLE in a Chinese Han population. Moreover, the subgroup analysis highlighted that IL-19 rs2243188 SNP was associated with the susceptibility to LN patients.

    ABSTRACT: Abstract Objective: To determine whether the cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) CT60 polymorphism (rs3087243) confers susceptibility to autoimmune thyroid disease (AITDs). Methods: A meta-analysis was performed using: (1) allelic contrast, (2) recessive model and (3) dominant model. Electronic search of PubMed, Medline and Chinese National Knowledge Infrastructure (CNKI) was conducted to select studies. Results: Finally, a total of 20 separate studies were available for the current meta-analysis: Graves' disease (GD): 18 studies including 1 Iranian, 6 Caucasian and 11 Asian populations; Hashimoto's thyroiditis (HT): seven studies including one Iranian, three Caucasian and three Asian populations. A significant association was found between the CTLA-4 CT60 polymorphism (rs3087243) and GD, with regard to comparisons between allele and genotype frequencies (all p < 0.001). After stratification by ethnicity, significant relationships were consistently identified both in Caucasian and Asian populations. Furthermore, the association between this allelic variant and HT risk was also found in overall and Asian populations (OR: 1.26, 95% CI: 1.10-1.44; OR: 1.45, 95% CI: 1.19-1.76, respectively). Conclusion: Taken together, our study suggested that the CT60 polymorphism (rs3087243) in CTLA-4 gene might confer susceptibility to the AITDs (GD/HT).

    ABSTRACT: Our previous study revealed that Schisandra polysaccharide (SCPP11) exerted excellent antitumor and immunomodulatory activities. In this investigation, the structure of SCPP11 was elucidated. The results indicated that SCPP11 has a backbone that is composed of 1,4-disubsituted-β-gal, 1,4-disubsituted-α-glu, 1,6-disubsituted-β-man and 1,4,6-disubsituted-α-gal. The branches was composed of 1,4-disubsituted-α-glu and 1-substitued-β-glu. The Mw and [Formula: see text] of the polymer molecules in 0.1M NaCl were 1.793×10(4)Da and 11nm, respectively. The exponent of [Formula: see text] versus Mw (0.39) suggested SCPP11 adopted a globular conformation with seldom random coil. Circular dichroism analysis revealed the presence of ordered structures in SCPP11. AFM and TEM further confirmed the agglomerated morphologies of SCPP11. In addition, it inferred the agglomerated conformation, branching structure and flexibility of chain are beneficial for exerting excellent activities. This information will be helpful in the recognition of biological systems for polysaccharides and the selection of active polysaccharide.

    ABSTRACT: The aim of this study was to estimate the associations between tumor necrosis factor (TNF) gene polymorphisms and type 1 diabetes (T1D) using meta-analysis. Relevant studies were searched using PubMed and Embase up to August 2013. A total of 32 comparisons from 21 studies examining the associations between TNF polymorphisms and T1D were included in the present meta-analysis. Our meta-analysis identified a significant association between TNF -308 A/G polymorphism A allele and T1D in all subjects [odds ratio (OR) 2.001, 95 % confidence interval (CI) 1.732-2.312). Significant associations of AA and AA+AG genotype of TNF -308 A/G polymorphism with genetic susceptibility to T1D were also found (OR 3.203, 95 % CI 2.373-4.324; OR 2.232, 95 % CI 1.881-2.649). After stratification by ethnicity, significant associations of T1D with TNF -308 A/G polymorphism under all genetic models (A allele and AA, AA+AG genotype) were still detected in European (OR 1.952, 95 % CI 1.675-2.274; OR 3.108, 95 % CI 2.169-4.455; OR 2.249, 95 % CI 1.870-2.706, respectively) and non-European populations (OR 2.152, 95 % CI 1.488-3.112; OR 3.439, 95 % CI 2.000-5.914; OR 2.207, 95 % CI 1.496-3.257, respectively). Our meta-analysis also revealed an association of TNF -857 T/C polymorphism T allele with T1D risk (OR 1.647, 95 % CI 1.431-1.896). Furthermore, analysis of TT and TT+TC genotype indicated the same result patterns as shown by the TNF -857 T/C polymorphism T allele (OR 2.206, 95 % CI 1.467-3.317; OR 1.762, 95 % CI 1.490-2.083). In conclusion, our meta-analysis results indicate that TNF -308 A/G and -857 T/C polymorphisms are involved in the genetic background of T1D.

    ABSTRACT: Yarrowia lipolytica is an oleaginous yeast capable of metabolizing glucose to lipids, which then accumulate intracellularly. However, it lacks the suite of cellulolytic enzymes required to break down biomass cellulose and cannot therefore utilize biomass directly as a carbon source. Toward the development of a direct microbial conversion platform for the production of hydrocarbon fuels from cellulosic biomass, the potential for Y. lipolytica to function as a consolidated bioprocessing strain was investigated by first conducting a genomic search and functional testing of its endogenous glycoside hydrolases. Once the range of endogenous enzymes was determined, the critical cellulases from Trichoderma reesei were cloned into Yarrowia.

    ABSTRACT: Advances in genomics have improved the ability to map complex genotype-to-phenotype relationships, like those required for engineering chemical tolerance. Here, we have applied the multiSCale Analysis of Library Enrichments (SCALEs; Lynch et al. (2007) Nat. Method.) approach to map, in parallel, the effect of increased dosage for >10(5) different fragments of the Escherichia coli genome onto furfural tolerance (furfural is a key toxin of lignocellulosic hydrolysate). Only 268 of >4,000 E. coli genes (∼6%) were enriched after growth selections in the presence of furfural. Several of the enriched genes were cloned and tested individually for their effect on furfural tolerance. Overexpression of thyA, lpcA, or groESL individually increased growth in the presence of furfural. Overexpression of lpcA, but not groESL or thyA, resulted in increased furfural reduction rate, a previously identified mechanism underlying furfural tolerance. We additionally show that plasmid-based expression of functional LpcA or GroESL is required to confer furfural tolerance. This study identifies new furfural tolerant genes, which can be applied in future strain design efforts focused on the production of fuels and chemicals from lignocellulosic hydrolysate.

    ABSTRACT: To develop a direct microbial sugar conversion platform for the production of lipids, drop-in fuels and chemicals from cellulosic biomass substrate, we chose Yarrowia lipolytica as a viable demonstration strain. Y. lipolytica is known to accumulate lipids intracellularly and is capable of metabolizing sugars to produce lipids; however, it lacks the lignocellulose-degrading enzymes needed to break down biomass directly. While research is continuing on the development of a Y. lipolytica strain able to degrade cellulose, in this study, we present successful expression of several xylanases in Y. lipolytica. The XynII and XlnD expressing Yarrowia strains exhibited an ability to grow on xylan mineral plates. This was shown by Congo Red staining of halo zones on xylan mineral plates. Enzymatic activity tests further demonstrated active expression of XynII and XlnD in Y. lipolytica. Furthermore, synergistic action in converting xylan to xylose was observed when XlnD acted in concert with XynII. The successful expression of these xylanases in Yarrowia further advances us toward our goal to develop a direct microbial conversion process using this organism.

    ABSTRACT: The aim of this study was to determine whether CTLA-4 gene variants were associated with susceptibility to inflammatory bowel disease (IBD). Meta-analysis was conducted on the association between CTLA-4 variants and IBD using: 1) allelic contrast, 2) the recessive model, and 3) the dominant model. A total of 9 relevant studies including 1,739 Crohn's disease (CD) cases, 10 relevant studies containing 1,017 ulcerative colitis (UC) cases and 2,685 healthy controls were involved in this meta-analysis. Overall, CTLA-4 +49A/G, -318C/T and CT60 variants were not associated with IBD susceptibility in all genetic models (P > 0.05). Stratification by ethnicity indicated a significant association between the CTLA-4 +49A/G variant and CD in Caucasian group (GG vs. GA + AA: OR = 0.723, 95% CI = 0.564-0.926, P = 0.010). In Asian group, meta-analysis showed a significant association between the CTLA-4 CT60 variant and UC (AA vs. AG + GG: OR= 0.375, 95% CI = 0.163-0.861, P = 0.021). Based on the published literature, this meta-analysis suggests that the CTLA-4 +49A/G variant may be related to CD susceptibility in Caucasians, and the CTLA-4 CT60 variant may be associated with UC susceptibility in Asians.

    ABSTRACT: This work presents a detailed review and comparative analysis of the process design and economics of n-butanol production using corn grain and corn stover. This includes reviewing the most recent n-butanol technologies; demonstrating the impact of key parameters (e.g. plant capacity, raw material pricing, yield) on the overall n-butanol process economics; and comparing how cellulosic biomass conversion technologies and challenges differ from traditional sugar-based n-butanol conversion technology. A major challenge of n-butanol production is the low n-butanol yield (compared to ethanol), resulting in higher production costs. However, recent research efforts have achieved significant yield improvements using a combination of genetic engineering, fermentation techniques, and integrated process development using continuous fermentation with online stripping to remove n-butanol during fermentation. This study presents the advances in n-butanol research for both sugar-based (corn) and cellulosic (corn stover) feedstocks, and also provides a comparison of overall process technologies and process economics. In addition, the results of a sensitivity analysis comparing various technologies, sugar yields, and coproduct distributions are discussed in order to provide research guidance. © 2013 Society of Chemical Industry and John Wiley & Sons, Ltd

    ABSTRACT: The aim of this study was to perform a meta-analysis of eligible studies to derive precise estimation of the association of interleukin-1 (IL-1), IL-10 and tumor necrosis factor (TNF)-α polymorphisms with Behcet's disease (BD). Odds ratios (ORs) and 95% confidence intervals (CIs) were used to assess the strength of the association. A total of 4003 cases and 4748 controls in 19 eligible studies were included in the meta-analysis. We examined the relationship between seven single nucleotide polymorphisms (SNPs) in the above-mentioned three cytokine genes and susceptibility to BD. Meta-analysis indicated the association between the cytokine gene polymorphisms in all study subjects in the allelic model (TNF-α -308A/G: OR = 0.73, 95% CI: 0.61-0.88, P = 0.001; IL-10 -819C/T: OR = 0.72, 95% CI: 0.66-0.78, P < 0.001; IL-10 -592C/A: OR = 0.74, 95% CI: 0.64-0.86, P < 0.001); the dominant model (TNF-α -308A/G: OR = 0.77, 95% CI: 0.64-0.92, P = 0.004; IL-10 -1082G/A: OR = 1.64, 95% CI: 1.10-2.44, P = 0.014); the recessive model (TNF-α -308A/G: OR = 0.27, 95% CI: 0.12-0.65, P = 0.003; IL-10 -819C/T: OR = 0.71, 95% CI: 0.57-0.90, P = 0.004). However, no significant evidence for the associations of IL-1α -889C/T, IL-1β -551C/T, IL-1β -3962C/T polymorphisms with BD susceptibility was detected. The present study might suggest that TNF-α -308A/G, IL-10 -1082G/A, -819C/T, -592C/A polymorphisms are associated with BD susceptibility.

    ABSTRACT: Emerging evidences were accumulated to support the view that aberrant interleukin-7 (IL-7) signaling might be associated with autoimmunity. Former studies demonstrated the single nucleotide polymorphism (SNP) rs6897932 C/T in the IL-7 receptor (IL-7R) gene was associated with susceptibility to autoimmune diseases, including multiple sclerosis and type I diabetes. Given these, this study was conducted to investigate whether an association existed between SNP rs6897932 and the susceptibility to systemic lupus erythematosus (SLE), a severe systemic autoimmune disease. In this context, 816 SLE patients and 816 controls from a Chinese population were recruited for this study, and the results showed that the major allele C of rs6897932 showed a higher frequency in SLE patients compared with controls (P = 0.039, C versus T); significant difference was also detected under a recessive model with regard to the distribution of genotype frequencies between SLE patients and controls (P = 0.041, CC versus CT + TT), which was not consistent with the results under a dominant model (P = 0.349, CC + CT versus TT). Moreover, association studies were also performed contraposing the relationship between the SNP rs6897932 C/T and lupus nephritis as well as 10 clinical features of SLE; however, no significant association signal was found regarding the distribution of allele and genotype frequencies between SLE patients positive and negative for the presence of 11 sub-phenotypes. In conclusion, the major allele C of SNP rs6897932 may be associated with increased SLE risk in Chinese populations, and further studies are still encouraged to shed light on the true associations between SLE and its susceptibility genes with respect to IL-7R gene.

    ABSTRACT: Previous study indicated that the refined polysaccharide from Schisandra could improve the CTX-induced inhibition of T and B lymphocytes proliferation. Accordingly, the enhanced antitumor and reduced toxicity effects of a low molecular weight purified polysaccharide from Schisandra (SCPP11) were investigated in 5-Fluorouracil (5-Fu) treated Heps-bearing mice. The results revealed that the SCPP11 (oral administration) exhibited a significant enhanced effect of antitumor activity when combined with 5-Fu. Moreover, a increased effect was also observed in boosting immunity functions when the Heps-bearing mice receiving SCPP11 combination with 5-Fu administration, including increased in thymus indexes and enhancing serum IL-2 and TNF-α secretion. In addition, SCPP11 could ameliorate the hematological and biochemical parameters changes induced by 5-Fu to normal level, and reduce the formation of MDA and enhance the activities of SOD in liver to against 5-Fu induced free radical damage. The above results suggested that the SCPP11 combined with 5-Fu presented enhanced effects on antitumor activity and the SCPP11 could attenuate the 5-Fu-induced toxicity effect. It could serve as a new and promising adjuvant for chemotherapy drugs.
