Improving the porosity of solid acids is essential for the catalytic conversion of macromolecular biomass. This work prepared mesoporous polymeric solid acids (HCPSA-NAP-x) by adjusting the copolymerization ratio of naphthalene and benzene and further sulfonated, and their catalytic activities in cellulose hydrolysis and oleic acid esterification were investigated. The effects of the ratio of naphthalene to benzene on the pore structure and the density of –SO3H were systematically investigated by Fourier transform infrared spectrometry (FT-IR), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), N2-physisorption and acid density titration. The characterization results demonstrated that HCPSA-NAP-x with a larger mesoporous volume could be prepared by adjusting the ratio of naphthalene to benzene. At the same time, the appropriate increase in the naphthalene ratio facilitated the introduction of –SO3H in HCPSA-NAP-x. The catalytic experiments showed that HCPSA-NAP-4, which has the largest mesoporous volume and higher –SO3H density in HCPSA-NAP-x, exhibited excellent catalytic activities and stabilities in cellulose hydrolysis and oleic acid esterification.

This paper studies computational methods for quasi-stationary distributions (QSDs). We first proposed a data-driven solver that solves Fokker–Planck equations for QSDs. Similar to the case of Fokker–Planck equations for invariant probability measures, we set up an optimization problem that minimizes the distance from a low-accuracy reference solution, under the constraint of satisfying the linear relation given by the discretized Fokker–Planck operator. Then we use coupling method to study the sensitivity of a QSD against either the change of boundary condition or the diffusion coefficient. The 1-Wasserstein distance between a QSD and the corresponding invariant probability measure can be quantitatively estimated. Some numerical results about both computation of QSDs and their sensitivity analysis are provided. [ABSTRACT FROM AUTHOR]

Background: PET-based radiomics features could predict the biological characteristics of primary prostate cancer (PCa). However, the optimal thresholds to predict the biological characteristics of PCa are unknown. This study aimed to compare the predictive power of 18F-PSMA-1007 PET radiomics features at different thresholds for predicting multiple biological characteristics. Methods: One hundred and seventy-three PCa patients with complete preoperative 18F-PSMA-1007 PET examination and clinical data before surgery were collected. The prostate lesions' volumes of interest were semi-automatically sketched with thresholds of 30%, 40%, 50%, and 60% maximum standardized uptake value (SUVmax). The radiomics features were respectively extracted. The prediction models of Gleason score (GS), extracapsular extension (ECE), and vascular invasion (VI) were established using the support vector machine. The performance of models from different thresholding regions was assessed using receiver operating characteristic curve and confusion matrix-derived indexes. Results: For predicting GS, the 50% SUVmax model showed the best predictive performance in training (AUC, 0.82 [95%CI 0.74–0.88]) and testing cohorts (AUC, 0.80 [95%CI 0.66–0.90]). For predicting ECE, the 40% SUVmax model exhibit the best predictive performance (AUC, 0.77 [95%CI 0.68–0.84] and 0.77 [95%CI 0.63–0.88]). As for VI, the 50% SUVmax model had the best predictive performance (AUC, 0.74 [95%CI 0.65–0.82] and 0.74 [95%CI 0.56–0.82]). Conclusion: The 18F-1007-PSMA PET-based radiomics features at 40–50% SUVmax showed the best predictive performance for multiple PCa biological characteristics evaluation. Compared to the single PSA model, radiomics features may provide additional benefits in predicting the biological characteristics of PCa. [ABSTRACT FROM AUTHOR]

Background: The difficulty of early diagnosis of bloodstream infection in the elderly patients leads to high mortality. Therefore, it is essential to determine some new methods of early warning of bloodstream infection in the elderly patients for timely adjustment of treatment and improvement of prognosis. Methods: Patients aged over 65 years with suspected bloodstream infections were included and divided into bloodstream infection (BSI) and non-bloodstream infection (non-BSI) groups based on blood culture results. The morphology of microparticles (MPs) was observed by using transmission electron microscopy, and the number of MPs was dynamically monitored by flow cytometry. Results: A total of 140 patients were included in the study: 54 in the BSI group and 86 in the non-BSI group. Total MPs (T-MPs) ≥ 6000 events/µL (OR, 7.693; 95% CI 2.944–20.103, P < 0.0001), neutrophil-derived MPs (NMPs) ≥ 500 events/µL (OR, 12.049; 95% CI 3.574–40.623, P < 0.0001), and monocyte counts ≤ 0.4 × 109/L (OR, 3.637; 95% CI 1.415–9.348, P = 0.007) within 6 h of fever were independently associated with bloodstream infection in the elderly patients. We also developed an early warning model for bloodstream infection in the elderly patients with an area under the curve of 0.884 (95% CI 0.826–0.942, P < 0.0001), sensitivity of 86.8%, specificity of 76.5%, positive predictive value of 70.8%, and negative predictive value of 89.8%. Conclusion: The early warning model of bloodstream infection based on circulating T-MPs, NMPs, and monocyte counts within 6 h of fever in the elderly patients was helpful in early detection of bloodstream infection and therefore promptly adjustment of treatment plan.

This paper studies the fuzzy hierarchical multimodal hub location problem for cargo delivery systems. It differs from traditional hub location problem in two ways. First, this paper constructs a hierarchical multimodal hub-and-spoke distribution network for the cargo delivery systems, which involves two transportation modes (road and air), two types of hubs (ground and airport) and three corresponding layers. Second, this paper develops a credibility-based fuzzy programming model capturing the uncertainty in travel time and handling time of the cargo delivery systems. This new model aims to minimize the latest arrival time (travel time plus handling time) for delivering cargoes from each pair of origin and destination nodes under diverse credibility of chance constraints. Under mild assumptions, the original model can be turned into an equivalent deterministic integer linear programming model. However, even for small instances of the problem, the equivalent model becomes too hard to be tackled by a general solver, e.g., CPLEX. This fact motivates the development of a two-stage heuristic procedure, wherein the first stage for the hub location subproblem is solved by a variable neighborhood search algorithm. These location solutions are then embedded into the second-stage process for the link assignment subproblem based on a shortest path method. To verify the proposed model and method, extensive numerical experiments are conducted on the well-known Turkish network data set. [ABSTRACT FROM AUTHOR]

Key message: Transcriptome analysis of maize embryogenic callus and somatic embryos reveals associated genes reprogramming, hormone signaling pathways and transcriptional regulation involved in somatic embryogenesis in maize. Somatic embryos are widely utilized in propagation and genetic engineering of crop plants. In our laboratory, an elite maize inbred line Y423 that could generate intact somatic embryos was obtained and applied to genetic transformation. To enhance our understanding of regulatory mechanisms during maize somatic embryogenesis, we used RNA-based sequencing (RNA-seq) to characterize the transcriptome of immature embryo (IE), embryogenic callus (EC) and somatic embryo (SE) from maize inbred line Y423. The number of differentially expressed genes (DEGs) in three pairwise comparisons (IE-vs-EC, IE-vs-SE and EC-vs-SE) was 5767, 7084 and 1065, respectively. The expression patterns of DEGs were separated into eight major clusters. Somatic embryogenesis associated genes were mainly grouped into cluster A or B with an expression trend toward up-regulation during dedifferentiation. GO annotation and KEGG pathway analysis revealed that DEGs were implicated in plant hormone signal transduction, stress response and metabolic process. Among the differentially expressed transcription factors, the most frequently represented families were associated with the common stress response or related to cell differentiation, embryogenic patterning and embryonic maturation processes. Genes include hormone response/transduction and stress response, as well as several transcription factors were discussed in this study, which may be potential candidates for further analyses regarding their roles in somatic embryogenesis. Furthermore, the temporal expression patterns of candidate genes were analyzed to reveal their roles in somatic embryogenesis. This transcriptomic data provide insights into future functional studies, which will facilitate further dissections of the molecular mechanisms that control maize somatic embryogenesis.

Philomycus bilineatus is a highly common gastropod mollusk pest in China and is also utilized to treat infectious diseases. However, no genomic resources are available for this non-model species. In the present study, the transcriptomic analysis of P. bilineatus was completed. After sequencing using the next generation sequencing technology, 9.11 Gb of clean reads were obtained, which led to the assembly and annotation of 145,523 transcripts and 125,690 unigenes. Unigenes were functionally classified using Gene Ontology (GO), euKaryotic Ortholog Groups of proteins (KOG), and Kyoto Encyclopedia of Genes and Genomes (KEGG). A total of 27,554 unigenes were assigned into 55 GO terms, 13,989 unigenes were differentiated into 26 KOG categories, and 16,368 unigenes were assigned to 229 KEGG pathways. Furthermore, 16,614 simple sequence repeats (SSRs), 38 olfactory genes, and 40 antimicrobial peptide/protein genes were identified. The transcriptome profile of P. bilineatus will provide a valuable genomic resource for further study, will promote the development of new pest management strategies through interference of chemosensory communication, and will support potential medicinal uses of this species.

Objectives: To investigate the role of methylation levels of the IFN regulatory factor 8 (IRF8) gene promoter in the development of ankylosing spondylitis (AS). Methods: In this study, we compared the methylation levels of the IRF8 gene promoter between 99 AS patients and 99 healthy controls using MethylTarget approach. Quantitative real-time reverse transcription-polymerase chain reaction (qRT-PCR) was performed to compare the mRNA levels of the IRF8 gene in the other 19 AS patients and 19 healthy controls. Results: Differential methylation was found in 91 CpG sites of the IRF8 gene promoter, and 4 CpG regions were highly methylated in AS patients compared to healthy controls (p < 0.05). In the verification stage, we found that the mRNA levels of the IRF8 gene in AS patients were significantly lower than that in controls (AS 0.77 (0.39–1.74), P = 0.038). Positive correlations between methylation of the IRF8 gene and the duration of disease, BASFI, and ESR were observed in AS patients. Conclusions: We found a significant hypermethylation of the IRF8 gene promoter and a downregulation of the mRNA levels of the IRF8 gene in AS patients. This suggests that aberrant methylation of the IRF8 gene promoter may probably contribute to the development and pathogenesis of AS through regulating the expression of mRNA. [ABSTRACT FROM AUTHOR]

Various studies have investigated the serum sclerostin and bone morphogenetic protein-2 (BMP-2) levels in patients with ankylosing spondylitis (AS), but the results were inconsistent. The aim of this meta-analysis was to synthetically assess the associations of serum levels of sclerostin and BMP-2 with AS. Multiple electronic databases were searched to locate relevant articles published before November 2018. Pooled standard mean difference (SMD) with 95% confidence interval (CI) was calculated by the random-effect model. Totally, 21 studies were included. Meta-analysis results showed no significant difference between AS group and control group in serum sclerostin levels (SMD = 0.098, 95% CI - 0.395 to 0.591, p = 0.697). Nevertheless, serum BMP-2 levels in AS patients were higher than that in controls (SMD = 1.184, 95% CI 0.209 to 2.159, p = 0.017). Subgroup analysis demonstrated that European and South American AS patients had lower serum levels of sclerostin than controls. AS patients with age ≥ 40 years, erythrocyte sedimentation rate (ESR) ≤ 20 mm/h and Bath Ankylosing Spondylitis Functional Index (BASFI) < 4 had statistically significant lower serum sclerostin concentrations compared to controls. Chinese and Korean AS patients as well as patients with lower CRP had higher serum BMP-2 levels than controls, and country may be a source of heterogeneity across the studies. No publication bias existed and sensitivity analysis confirmed the stability of results. Serum BMP-2, but not sclerostin levels may be closely related to the development of AS.

Key message: A Sec14-like protein, ZmSEC14p , from maize was structurally analyzed and functionally tested. Overexpression of ZmSEC14p in transgenic Arabidopsis conferred tolerance to cold stress. Abstract: Sec14-like proteins are involved in essential biological processes, such as phospholipid metabolism, signal transduction, membrane trafficking, and stress response. Here, we reported a phosphatidylinositol transfer-associated protein, ZmSEC14p (accession no. KT932998), isolated from a cold-tolerant maize inbred line using the cDNA-AFLP approach and RACE-PCR method. Full-length cDNA that consisted of a single open reading frame (ORF) encoded a putative polypeptide of 295 amino acids. The ZmSEC14p protein was mainly localized in the nucleus, and its transcript was induced by cold, salt stresses, and abscisic acid (ABA) treatment in maize leaves and roots. Overexpression of ZmSEC14p in transgenic Arabidopsis conferred tolerance to cold stress. This tolerance was primarily displayed by the increased germination rate, root length, plant survival rate, accumulation of proline, activities of antioxidant enzymes, and the reduction of oxidative damage by reactive oxygen species (ROS). ZmSEC14p overexpression regulated the expression of phosphoinositide-specific phospholipase C, which cleaves phosphatidylinositol 4,5-bisphosphate (PIP2) and generates second messengers (inositol 1,4,5-trisphosphate and 1,2-diacylglycerol) in the phosphoinositide signal transduction pathways. Moreover, up-regulation of some stress-responsive genes such as CBF3, COR6.6, and RD29B in transgenic plants under cold stress could be a possible mechanism for enhancing cold tolerance. Taken together, this study strongly suggests that ZmSEC14p plays an important role in plant tolerance to cold stress. [ABSTRACT FROM AUTHOR]

To identify the crosstalk between gene expression and metabolism in response to cold, drought and salt stresses, digital gene expression (DGE) analysis was performed on maize ( Zea mays L.) seedlings subjected to these stresses. A total of 103,953 (70.79 %), 111,130 (68.62 %), 94,435 (69.33 %) and 94,577 (68.92 %) tags were matched to reference genes. The most differentially regulated tags, with a log2 ratio ≥1 or ≤−1 ( P < 0.01 and FDR ≤0.001), were further analysed. Many genes and biological pathways were affected by multiple abiotic stresses. In particular, expression changes for the gibberellin (GA) metabolic genes could improve understanding of the molecular basis of the response of the GA pathway to stress conditions. In addition, a large dataset of tag-mapped transcripts was obtained that provide a strong basis for future research on the response to abiotic stress in maize. And a new list of candidate targets for functional studies on genes involved in cold, drought and salt stresses has been generated. In this study, we revealed complex changes at the transcriptional level in maize seedlings under different abiotic stresses. Such studies could lead to a better understanding of the genetic basis of the maize response to different environmental stimuli and would be essential for improving the abiotic stress tolerance of maize.

A proteomic approach based on two-dimensional electrophoresis (2-DE) and mass spectrometry was performed to investigate somatic embryogenesis in the H99 inbred maize line by comparing embryogenic and non-embryogenic callus. Protein spots ( n = 42) were differentially expressed between embryogenic calli and non-embryogenic calli according to our image analysis. Among them, 33 proteins were differentially expressed by at least threefold, with 15 up-regulated and 18 down-regulated in the embryogenic callus versus the non-embryogenic callus. However, only nine proteins were expressed in either of the calli. Twenty-nine protein spots were identified using mass spectrometry analysis and classified into several categories based on the matrix-science MASCOT and NCBI databases. These categories included cell proliferation (10.34 %), transcription and protein processing (17.24 %), stress response (10.34 %), signal transduction (3.45 %), metabolism and energy (48.28 %) and hypothetical function (10.34 %). Their putative roles are discussed according to their relevance in somatic embryogenesis. Real-time reverse transcription polymerase chain reaction analysis revealed that the expression levels of five selected genes were consistent with the profiles detected in the 2-DE gels, further confirming the proteomic analysis. This study is the first comparative proteome analysis between the embryogenic callus and the non-embryogenic callus of the H99 inbred line. Our results show the differentially expressed proteins between the two callus types and reveal some key proteins that may have significant roles in molecular events during somatic embryogenesis in this species.

DNA methylation plays a vital role in tuning gene expression in response to environmental stimuli. Here, methylation-sensitive amplified polymorphisms (MSAP) were used to assess the effect of cold stress on the extent and patterns of DNA methylation in maize seedlings. Overall, cold-induced genome-wide DNA methylation polymorphisms accounted for 32.6 to 34.8% of the total bands at the different treatment time-points. It was demonstrated that the extent and pattern of DNA methylation was induced by cold stress through the cold treatment process and that the demethylation of fully methylated fragments was the main contributor of the DNA methylation alterations. The sequences of 28 differentially amplified fragments relevant to stress were successfully obtained. Under the cold stress, demethylation was detected in most fragments. BLAST results indicate that the homologues of these fragments are involved in many processes, including hormone regulation, cold response, photosynthesis, and transposon activation. The expression analysis demonstrated an increase in the transcription of five demethylated genes. Despite the fact that DNA methylation changes and cold acclimation are not directly associated, our results may indicate that the specific demethylation of genes is an active and rapid epigenetic response to cold in maize during the seedling stage, further elucidating the mechanism of maize adaptation to cold stress.

Somatic embryogenesis is a complex developmental process that offers great potential for plant propagation. Although many studies have shown that the generation of embryonic cells from somatic cells is accompanied by the synthesis of RNA and DNA and by elevated enzymatic activity, the mechanism of the onset of somatic embryogenesis is not well understood. cDNA-amplified fragment length polymorphism analysis was used to evaluate the gene expression pattern in embryogenic and non-embryogenic of the inbred maize line H99 during the process of embryogenesis. We identified a total of 101 candidate genes associated with the formation of maize embryonic calli. Based on the sequence analysis, these genes included 53 functionally-annotated TDFs involved in such processes as energy production and conversion, cell division and signal transduction, suggesting that somatic embryogenesis undergoes a complex process. Two full-length cDNA sequences, encoding KHCP (kinesin heavy chain like protein) and TypA (tyrosine phosphorylation protein A), and partial sequences, encoding ARF-GEP (guanine nucleotide-exchange protein of ADP ribosylation factor) homologs, were isolated from embryonic calli of maize and named ZmKHCP, ZmTypA and ZmARF-GEP, respectively. Finally, the real-time qRT-PCR results showed that the expression levels of the three genes were significantly higher in the embryonic calli than the non-embryonic calli. Thus, this study provides important clues to understanding the induction of somatic embryogenesis in maize. The candidate genes associated with the formation of embryonic calli may offer additional insights into the mechanism of somatic embryogenesis, and further research on the three candidate genes may determine their role in increasing the rate of induction of embryonic calli, which may aid in the development of cultivars through transgenic breeding.

This study was conducted to clarify the associations of tumor necrosis factor-α induced protein 3 (TNFAIP3) and TNFAIP3-interacting protein 1 (TNIP1) genetic polymorphisms with ankylosing spondylitis (AS) susceptibility. Five single nucleotide polymorphisms (SNPs) in TNFAIP3 gene and four in TNIP1 gene were genotyped in 667 AS patients and 667 matched healthy controls. Genotypes and haplotype analysis were conducted by using SPSS 23.0 and Haploview 4.2 software. The T allele and CT genotype in TNFAIP3 rs10499194 were significantly associated with a reduced AS risk (T allele vs. C allele, OR = 0.619, 95% CI = 0.430–0.889, P = 0.009; CT vs. CC, OR = 0.603, 95% CI = 0.416–0.875, P = 0.007). However, no association remained significant after Bonferroni correction. The rs13207033A- rs10499194T haplotype of TNFAIP3 conferred a protective effect on AS susceptibility. Stratification analyses suggested that rs10499194 polymorphism decreased the risk of AS in the male subgroup, subgroup aged ≥ 29, HLA-B27 positive subgroup as well as the subgroups of BASFI < 4 and BASDAI < 4 (all P < 0.05). Furthermore, the functional annotation suggested a potential function of rs10499194 mutation. Our results demonstrated that TNFAIP3 rs10499194 polymorphism may be associated with a reduced risk of AS. [ABSTRACT FROM AUTHOR]

Background: Rising prostate-specific antigen (PSA) levels following radical prostatectomy are indicative of a poor prognosis, which may associate with periprostatic adipose tissue (PPAT). Accordingly, we aimed to construct a dynamic online nomogram to predict tumor short-term prognosis based on 18F-PSMA-1007 PET/CT of PPAT.Data from 268 prostate cancer (PCa) patients who underwent 18F-PSMA-1007 PET/CT before prostatectomy were analyzed retrospectively for model construction and validation (training cohort: n = 156; internal validation cohort: n = 65; external validation cohort: n = 47). Radiomics features (RFs) from PET and CT were extracted. Then, the Rad-score was constructed using logistic regression analysis based on the 25 optimal RFs selected through maximal relevance and minimal redundancy, as well as the least absolute shrinkage and selection operator. A nomogram was constructed to predict short-term prognosis which determined by persistent PSA.The Rad-score consisting of 25 RFs showed good discrimination for classifying persistent PSA in all cohorts (all P < 0.05). Based on the logistic analysis, the radiomics-clinical combined model, which contained the optimal RFs and the predictive clinical variables, demonstrated optimal performance at an AUC of 0.85 (95% CI: 0.78—0.91), 0.77 (95% CI: 0.62—0.91) and 0.84 (95% CI: 0.70—0.93) in the training, internal validation and external validation cohorts. In all cohorts, the calibration curve was well-calibrated. Analysis of decision curves revealed greater clinical utility for the radiomics-clinical combined nomogram.The radiomics-clinical combined nomogram serves as a novel tool for preoperative individualized prediction of short-term prognosis among PCa patients.Methods: Rising prostate-specific antigen (PSA) levels following radical prostatectomy are indicative of a poor prognosis, which may associate with periprostatic adipose tissue (PPAT).

The aim of our study was to explore the relationship between circulating T cells and ankylosing spondylitis (AS) and to find the role of the CD8+CD122+ T cells in the pathogenesis and progression of AS. With the method of case-control design, flow cytometry was performed to quantitatively determine the percentage of circulating CD8+CD122+ T cells in peripheral blood mononuclear cells from established AS patients and age- and gender-matched healthy controls. Serum levels of inflammatory cytokines like interleukin-2, interleukin-10, interleukin-15, TGF-β1, and TNF-ɑ were detected by enzyme-linked immunosorbent assay. The t test was used to compare differences between groups, correlation analysis with Spearman rank test and Pearson correlation was performed. The percentage of circulating CD8+CD122+ T cells were significantly increased in AS patients compared with controls (Z = − 4.917, P = 0.001). Plasma IL-2, IL-10, IL-15, TGF-β1, and TNF-ɑ levels between cases and controls were analyzed but no statistically significant differences were found. The percentage of circulating CD8+CD122+ T cells were not significantly different in the two groups of patients with AS whether they were treated or not. In addition, the percentage of circulating CD8+CD122+ T cells was positively correlated with disease duration, CRP, and ASDAS-CRP. The CD8+CD122+ T cells in the peripheral blood of AS patients may be involved in the development of AS, and they may coordinate regulate inflammation and immune dysregulation in patients with AS, which may play an important role in the pathogenesis and prognosis of AS.The aim of our study was to explore the relationship between circulating T cells and ankylosing spondylitis (AS) and to find the role of the CD8+CD122+ T cells in the pathogenesis and progression of AS.

In addition, the percentage of circulating CD8+CD122+ T cells was positively correlated with disease duration, CRP, and ASDAS-CRP. The CD8+CD122+ T cells in the peripheral blood of AS patients may be involved in the development of AS, and they may coordinate regulate inflammation and immune dysregulation in patients with AS, which may play an important role in the pathogenesis and prognosis of AS.The aim of our study was to explore the relationship between circulating T cells and ankylosing spondylitis (AS) and to find the role of the CD8+CD122+ T cells in the pathogenesis and progression of AS. With the method of case-control design, flow cytometry was performed to quantitatively determine the percentage of circulating CD8+CD122+ T cells in peripheral blood mononuclear cells from established AS patients and age- and gender-matched healthy controls. Serum levels of inflammatory cytokines like interleukin-2, interleukin-10, interleukin-15, TGF-β1, and TNF-ɑ were detected by enzyme-linked immunosorbent assay. The t test was used to compare differences between groups, correlation analysis with Spearman rank test and Pearson correlation was performed. The percentage of circulating CD8+CD122+ T cells were significantly increased in AS patients compared with controls (Z = − 4.917, P = 0.001).
