Objective: There has been growing body of literatures showing that chronic inflammation might play an important role in cancer development. This meta-analysis aimed to assess the association between the dietary inflammation index (DII) score and gynecological cancers. Methods: A systematic search of PubMed, EMBASE and Web of Science up until October 20, 2018 was carried out to retrieve all related cohort and case-control studies. The summary risk assessments were pooled using random-effects models. The dose-response relationship was estimated by linear relationship model. Results: Twelve case-control studies (10,774 cases/15,958 controls) and six prospective cohort studies (330,363 participants/23,133 incident cases) were included in this meta-analysis. The pooled adjusted relative risk (RR) of gynecological cancers for the highest DII category compared to the lowest category was 1.38, (95% confidence intervals [CIs], 1.21–1.56, p<0.001]. A positive dose-response relationship was also noticed. Stratified by study design indicated that, the pooled RRs was significantly higher for case-control studies than cohort studies (p for interaction<0.001), for studies conducted among participants with body mass index (BMI) ≥25 kg/m2 than participants with BMI <25 kg/m2 (p for interaction=0.026), among participants with ovarian cancer and endometrial cancer than participants with breast cancer (p for interaction = 0.038). Meta-regression analysis further confirmed that study design significantly contributed to inter-study heterogeneity (p<0.001). Conclusion: This meta-analysis suggests that elevated DII is independently associated with a higher risk of gynecological cancers, especially patients with ovarian cancer and endometrial cancer and among obese participants.

There is an increasing worldwide interest in bioethanol production from agricultural, industrial, and urban residues for both ecological and economic reasons. The acid hydrolysis of cassava pulp to reducing sugars and their fermentation to ethanol were evaluated in a fibrousbed bioreactor with immobilized Δldh, a genetically engineered Thermoanaerobacterium aotearoense. A maximum yield of total reducing sugars of 53.5% was obtained after 8 h of hydrolysis at 85oC in 0.4 mol/L hydrochloric acid with a solid-to-liquid ratio of 1:20, which was optimized by using an orthogonal design based on preliminary experiments. In the FBB, the fed-batch fermentation, using glucose as the sole carbon source, gave a maximum ethanol production of 38.3 g/L with a yield of 0.364 g/g in 100 h; whereas the fed-batch fermentation, using xylose as the sole carbon source, gave 34.1 g/L ethanol with a yield of 0.342 g/g in 135 h. When cassava pulp hydrolysate was used as a carbon source, 39.1 g/L ethanol with a yield of 0.123 g/g cassava pulp in185 h was observed, using the fed-batch fermentation model. In addition, for repeated batch fermentation of cassava pulp hydrolysate carried out in the fibrous-bed bioreactor, long-term operation with high ethanol yield and volumetric productivity were achieved. The above results show that the acid hydrolysate of cassava pulp can be used for ethanol production in a fibrous-bed bioreactor, although some inhibition phenomena were observed during the process of fermentation.

Effect of temperature on the development of Echinothrips americanus Morgan (Thysanoptera: Thripidae) with special reference to the number of generations

Liang Zhu,Ze-Hua Wang,Ya-Jun Gong,Li-Jun Cao,Shu-Jun Wei 한국응용곤충학회 2017 Journal of Asia-Pacific Entomology Vol.20 No.4

The thrips Echinothrips americanus Morgan (Thysanoptera: Thripidae) was recently reported in China. The effect of temperature on its development was investigated and the potential area of further dispersal was predicted by estimation of its generations in China. First instar larvae developed to adults on green peppers Capsicum anuum at all constant temperatures (16, 19, 22, 25, 28, 31 and 34 °C) except for 34 °C, at which they developed only as far as the second instar. The percentage surviving of immature stages were not significantly different at the other six temperatures (range 32.10%–52.72%). The developmental times from egg to adult ranged from 11.68 to 45.13 days and were negatively correlated with temperature. There were significant differences between male and female immature stages in their developmental time at 22 °C and 25 °C. Regression analysis indicated that both the Lactin and linear models could describe the relationship between developmental rate and temperature for immature stages but a slightly higher coefficient of determination was obtained with the Lactin model. The high-temperature threshold and the optimum temperature for development were 32.04 °C and 31.79 °C, respectively, estimated by the Lactin model. The low-temperature threshold for development was 11.35 °C and thermal constant was 229.76 degree-days for immature stages, estimated by the linear model. The models predicted that E. americanus could have produced 8–10 generations per year under field conditions in Beijing (N39°56′, E116°17′) and Yangling (N34°12′, E108°7′) from 2002 to 2012. The potential risk posed by E. americanus to crops in different regions of China was discussed.

Jiong-Feng Liang,Ze-Ping Yang,Ping-Hua Yi,Jian-Bao Wang 사단법인 한국계산역학회 2015 Computers and Concrete, An International Journal Vol.16 No.2

This paper reports the results of an experimental study on the compressive strength and the stress-strain curve (SSC) of recycled fine glass aggregate concrete with different replacement percentages of recycled fine glass aggregate. The results show that the recycled fine glass aggregate contents have significant impact on the workability, compressive strength, the elastic modulus, the peak and the ultimate strains of recycled fine glass aggregate concrete. Analytical expressions for the stress–strain relationship of recycled fine glass aggregate concrete are given, which can satisfactorily describe the effect of the recycled fine glass aggregate on the SSC.

Stress-strain relationship for recycled aggregate concrete after exposure to elevated temperatures

Jiong-Feng Liang,Ze-Ping Yang,Ping-Hua Yi,Jian-Bao Wang 사단법인 한국계산역학회 2017 Computers and Concrete, An International Journal Vol.19 No.6

In this paper, the effects of elevated temperatures on the strength and compressive stress-strain curve (SSC) of recycled coarse aggregate concrete with different replacement percentages are presented. 90 recycled coarse aggregate concrete prisms are heated up to 20, 200, 400, 600, 800°C. The results show that the compressive strength, split tensile strength, elastic modulus of recycled aggregate concrete specimens decline significantly as the temperature rise. While the peak strain increase of recycled aggregate concrete specimens as the temperature rise. Compared to the experimental curves, the proposed stress-strain relations for recycled aggregate concrete after exposure elevated temperatures can be used in practical engineering applications.

The alfalfa plant bug Adelphocoris lineolatus (Goeze) (Hemiptera: Miridae), a serious pest of several agricultural crops, is extremely attracted by flowering plants to perform season host switching. Generally, chemoreception of A. lineolatus plays a crucial role in detecting food sources, locating mates and oviposition sites. In addition, odorant carrier proteins are believed to participate in the initial chemical communication and perception in insects. In this work, we identified 31 putative odorant carrier protein genes from the antennal transcriptomes of A. lineolatus, including 17 new odorant binding proteins (OBPs), 10 new chemosensory proteins (CSPs) and four Niemann-Pick type C2 proteins (NPC2s). Phylogenetic analysis demonstrated that the OBP and CSP genes from four mirid bug species (A. lineolatus, Adelphocoris suturalis, Apolygus lucorum and Lygus lineolaris) had a relatively close evolutionary relationship. Regular patterns and key conserved motifs of OBPs and CSPs in Hemiptera insects are also identified by using Multiple EM for Motif Elicitation (MEME) tool. Tissue expression profiles analysis showed that nine of the 17 OBPs, 10 CSPs and two of the four NPC2s were primarily or uniquely expressed in the adult antennae suggesting their putative roles in chemoreception. Our study provides the first insight into the roles of odorant carrier proteins in chemoreception of A. lineolatus, which will help to facilitate biological functions of odorant carrier proteins and develop novel insect behavioral regulation strategy

Genome-wide identification and evolution of TC1/Mariner in the silkworm (Bombyx mori) genome

Li‑Qin Xie,Ping‑Lan Wang,Shen‑Hua Jiang,Ze Zhang,Hua‑Hao Zhang 한국유전학회 2018 Genes & Genomics Vol.40 No.5

TC1/Mariner transposons belong to class II transposable elements (TEs) that use DNA-mediated “cut and paste” mechanism to transpose, and they have been identified in almost all organisms. Although silkworm (Bombyx mori) has a large amount of TC1/Mariner elements, the genome wide information of this superfamily in the silkworm is unknown. In this study, we have identified 2670 TC1/Mariner (Bmmar) elements in the silkworm genome. All the TEs were classified into 22 families by means of fgclust, a tool of repetitive sequence classification, seven of which was first reported in this study. Phylogenetic and structure analyses based on the catalytic domain (DDxD/E) of transposase sequences indicated that all members of TC1/Mariner were grouped into five subgroups: Mariner, Tc1, maT, DD40D and DD41D/E. Of these five subgroups, maT rather than Mariner possessed most members of TC1/Mariner (51.23%) in the silkworm genome. In particular, phylogenetic analysis and structure analysis revealed that Bmmar15 (DD40D) formed a new basal subgroup of TC1/Mariner element in insects, which was referred to as bmori. Furthermore, we concluded that DD40D appeared to intermediate between mariner and Tc1. Finally, we estimated the insertion time for each copy of TC1/Mariner in the silkworm and found that most of members were dramatically amplified during a period from 0 to 1 mya. Moreover, the detailed functional data analysis showed that Bmmar1, Bmmar6 and Bmmar9 had EST evidence and intact transposases. These implied that TC1/Mariner might have potential transpositional activity. In conclusion, this study provides some new insights into the landscape, origin and evolution of TC1/Mariner in the insect genomes.
