The mitochondrial genome (mitogenome) is an important topic for comparative and evolutionary genomics, as well as phylogenetic and population genetics. However, there are limited data regarding the mitochondrial genome available of Pyraloidea, one of the largest superfamilies in Lepidoptera. In this report, we present the complete mitogenome of the meadow moth, Loxostege sticticalis L. (Lepidoptera: Pyraloidea: Crambidae), which is a serious economic pest of both crops and weedsworldwide, thereby enhancing the available genomic information for Pyraloidea. This circular genome is 15,218 bp in length, containing 13 protein-coding genes (PCGs), two rRNA genes (rRNAs), and 22 tRNA genes (tRNAs), with a typical gene orientation and order comparable to other sequenced Pyraloidea insects. The genome composition of the major strand exhibits highly AT bias (80.82%), with a slightly positive AT skew indicating the occurrence of more As than Ts. The L. sticticalis mitogenome has a total of 130 bp of intergenic spacer sequences spread over 15 regions, ranging in size from 1 to 48 bp, of which only two are common among the 23 total Pyraloidea moths that have data collected on the mitogenome (one is located between tRNAGln and ND2 with variation change in length and a limited sequence conservation, and the other is located between tRNASer(UCN) and ND1 with a conserved 6 bp motif ‘ATACTA’). The A + Trich region of 331 bp in the genome is comprised of non-repetitive sequences but contains an ATAGN motif followed by a poly-T stretch of 17 bp, a microsatellite-like (TA)11 element preceded by an ATTTA motif, and a poly-A stretch upstream tRNAMet. These conserved structures identified in the A + T-rich region are presented in all of the sequenced Pyraloidea species. We provide a mitogenome-based phylogeny of Pyraloidea species, in which L. sticticalis shares close ancestry to Ostrinia species with substantial evidence. Our phylogenetic analyses strongly divide Crambidae into two sister lineages, one consisting of Pyraustinae and Spilomelinae, while the other contains Crambinae, Acentropinae, Scopariinae, Schoenobiinae and Glaphyriinae. The mitogenome dataset also supports the basal split between Pyraustinae and Spilomelinae.

In this study, peanut hulls powder (PHP) wastreated via mechanical activation (MA) and divided intothree groups (control, PHP150 and PHP250). Physicochemicalproperties including mean particle size distribution(MPSD), powder properties, solubility and in vitro proteindigestibility of PHP were then investigated. The resultsshowed that MA could decrease the particle size of PHP bydestroying its crystal structure, resulting in an increase ofamorphization and a decrease of crystallinity and crystallinesize. The results of in vitro protein digestibility and crudefi ber contents showed that MA increased the protein digestibilityof PHP by 43.32% and 74.70% ( P < 0.05), while crudefi ber content was decreased by 0.42% and 26.65% ( P < 0.05). These fi ndings indicated a large application potential of MAin PHP treatment.

This paper presents an improved method for predicting the bearing capacity of single jacked pile based on piezocone penetration test (CPTu) data which contain tip resistance (qt), side friction ( fs) and excess dynamic pore water pressure (u2). Firstly, the average value of qt was determined to calculate the pile unit base resistance according to the influence zone of the logarithmic spiral concerning the effect of soil types. Secondly, fs and u2 were used to calculate the pile unit shaft resistance considering the effect of friction fatigue. The pile jacking force was obtained in terms of unit base resistance and unit shaft resistance. The ultimate bearing capacity was finally determined using pile jacking force multiplied by a force ratio denoted as Rf. The ultimate bearing capacities calculated for two case projects show a good agreement with the measured results, which indicates that the proposed method is feasible and effective. Reliability assessment was carried out on the proposed method and other five estimation methods with respect to the reliability index obtained by advanced first-order second-moment (AFOSM) method. Comparison result showed that the method proposed in this study has a higher reliability index over other five existing methods. Therefore, the proposed method can be used as a reliable alternative to predict the bearing capacity in the engineering practice of jacked pile foundation.

Xanthine dehydrogenase (EC1.1.1.204; XDH) plays an important role in purine catabolism that catalyzes the oxidative hydroxylation of hypoxanthine to xanthine and of xanthine to uric acid. Long attributed to its role in recycling and remobilization of nitrogen, recently, XDH is implicated in plant stress responses and acclimation, such research efforts, however, have thus far been restricted to Arabidopsis XDH-knockdown/knockout studies. This study, using an ectopic overexpression approach, is expected to provide novel findings. In this study, a XDH gene from Vitis vinifera, named VvXDH, was synthesized and overexpressed in Arabidopsis, the transgenic Arabidopsis showed enhanced salt tolerance. The VvXDH gene was investigated and the results demonstrated the explicit role of VvXDH in conferring salt stress by increasing allantoin accumulation and activating ABA signaling pathway, enhancing ROS scavenging in transgenic Arabidopsis. In addition, the water loss and chlorophyll content loss were reduced in transgenic plants; the transgenic plants showed higher proline level and lower MDA content than that of wild-type Arabidopsis, respectively. In conclusion, the VvXDH gene has the potential to be applied in increasing allantoin accumulation and enhancing the tolerance to abiotic stresses in Arabidopsis and other plants.

Dynamic Characteristics of Saturated Soft Clays under Cyclic Loading in Drained Condition
Yong-hong Miao,Ruo-Yu Sheng,Jie Yin,Fan-Bo Zhou,Jian-fei Lu 대한토목학회 2020 KSCE JOURNAL OF CIVIL ENGINEERING Vol.24 No.2
This study presents an experimental investigation on the effects of cyclic loading waveform and cyclic stress ratio (CSR) on dynamic behaviors through laboratory tests on a source of soft clay under cyclic loading in drained condition. Test results showed that under different cyclic loading waveforms at a given frequency (f = 1 Hz) and CSR = 0.6, the axial strain increases significantly at a relatively lower number of cycles (N) and then became stable, while the axial strain consistently decreases with the increasing N and tend to be stable. At a given N, specimen under sine wave cyclic loads shows a higher axial strain rate than that under triangle wave or square cyclic loads. Test results also indicated that at different CSRs, the axial strain increases rapidly at a relatively lower N and then gradually tends to be stable with the increasing N at lower CSR yet there is no stable trend for specimens at higher CSR, which indicates there is a critical value of CSR. It is recommended to apply the cyclic loading in sine waveform with CSR close to and less than the critical value to get a better treatment effect.

The objective of this study was to analyze the target genes and regulatory function of miR-34a in Megalobrama amblycephala using second-generation highthroughput sequencing and bioinformatic tools. Functional enrichment analysis was performed by gene ontology. MiR- 34a and target gene expression levels were measured in M. amblycephala fed normal and high-carbohydrate diets. The results revealed that miR-34a was highly conserved in several species, and miR-34a of M. amblycephala has a close evolutionary relationship to that of zebrafish and common carp. miRanda, TargetScan, RNAhybrid predicted 5,185, 6,282 and 2,168 target genes, respectively, and 645 target genes were in common. According to annotation information, the target genes were enriched in phosphate metabolism, glycerophospholipid metabolism, Golgi vesicle transport, cell division, and other biological processes (P < 0.05). Pathway enrichment analysis revealed that these target genes were mainly enriched in alpha-linolenic acid and linoleic acid metabolism, ether lipid metabolism, VEGF signaling pathway, Fc epsilon RI signaling pathway, GnRH signaling pathway, and MAPK signaling pathway (P < 0.05). The regulatory role of miR-34a was more significant in the liver than in the brain of M. amblycephala. MiR-34a regulates glucose lipid homeostasis induced by high glucose diets by upregulating hepatic PI3K/Akt, FOXO, and TOR signaling pathways.
