Abstract Gastric cancer (GC) is the most common digestive system malignant tumor and second most common cause of cancer-related death. Even for the early gastric cancer, after radical operation, perioperative and postoperative chemotherapy the recurrence and metastasis are also high. 5-year overall survival of all GC patients is only 10–15%. Chemo-resistance still poses a major obstacle to successful treatment of GC. The aberrant expression of TUG1 (Taurine Upregulated Gene 1) was closely related to chemo-resistance and metastasis in many cancers. Here we over-expressed TUG1 in GC cell line SGC-7901 and MGC-803. We compared the migration ability and sensitivity of cisplatin (CDDP),… More >

Abstract Fatal traffic accidents in urban areas can adversely affect the urban road traffic system and pose many challenges for urban traffic management. Therefore, it is necessary to first classify emergency responses to such accidents and then handle them quickly and correctly. The aim of this paper is to develop an evaluation index system and to use appropriate methods to investigate emergency-response classifications to fatal traffic accidents in Chinese urban areas. This study used a multilevel hierarchical structural model to determine emergency-response classification. In the model, accident attributes, urban road network vulnerability, and institutional resilience were used as classification criteria. Each… More >

Abstract This study aimed to explore LncRNA TUG1 targeted miR-222-3p in the proliferation and invasion of breast cancer (BC) cells. Seventy-six BC patients admitted to our hospital and 62 health check-ups at the same time were selected as the research objects. Among them, the former was seen as the observation group (OG), and the latter was considered as the control group (CG). The clinical significance of LncRNA TUG1 and miR-222-3p in BC was detected. Human BC cell MCF7 and normal human breast epithelial cell MCF-10A were purchased. After cells were transfected with LncRNA TUG1 and miR-222-3p, their proliferation, invasion, and apoptosis… More >

Abstract Primary seed dormancy is an adaptive strategy that prevents germination for viable seeds in harsh environment, ensuring seeds germination under favorable condition. Accurately inducing seeds germination in a controllable manner is important for crop production. Thus searching the chemicals that efficiently breaks seed dormancy is valuable. DOG1 protein abundance in the freshly harvested seed is high, and its level is correlated to seed dormancy intensity, thus DOG1 is regarded as the timer to evaluate the seed dormancy degree. In this study, we found the carbon monoxide (CO) donor treatment, the transgenic line with high CO content, showed lower seed dormancy,… More >

Abstract Primary seed dormancy is a critical trait for sustainable agricultural development, ensuring seed germination under favorable conditions. The induction, maintenance and release of seed dormancy is a complicated physiological process that is strictly controlled by a variety of endogenous signals and environmental factors. In Arabidopsis, DOG1 (DELAY OF GERMINATION 1) is identi- fied as the main quantitative trait locus (QTL) of seed dormancy, which contributes to deep dormancy in the Cvi ecotype. In recent years, considerable progress has been made to elucidate the molecular regulatory mechanism by which DOG1 controls seed dormancy. In this review, we describe a series of… More >

Abstract This paper proposes a novel method of lane detection, which adopts VGG16 as the basis of convolutional neural network to extract lane line features by cavity convolution, wherein the lane lines are divided into dotted lines and solid lines. Expanding the field of experience through hollow convolution, the full connection layer of the network is discarded, the last largest pooling layer of the VGG16 network is removed, and the processing of the last three convolution layers is replaced by hole convolution. At the same time, CNN adopts the encoder and decoder structure mode, and uses the index function of the… More >

Abstract Genomic instability and mutations caused by increases in oxidative stress during pregnancy can damage the fetoplacental unit and can upshot preterm birth. Oxidative damage to DNA may possibly be involved in etiology of preterm birth (PTB) which can be repaired by DNA repair gene. In the present study, we assessed the association of base excision repair gene family by analyzing the association of single nucleotide polymorphisms and genes expression in 8-oxoguanine glycosylase-1 (OGG1) and apurinic-apyrimidinic endonuclease 1 (APE1) genes with risk of preterm birth in Saudi women. We analyzed genotypes of four single nucleotide polymorphisms (SNPs) (rs1052133, rs293795, rs2072668 and… More >

Abstract X-ray repair cross-complementing protein 1 (XRCC1) could repair cisplatin-induced DNA damage. XRCC1 Arg399Gln and Arg194Trp variants alter XRCC1 expression and function, leading to changes in cancer sensitivity to cisplatin treatment. This study aimed to investigate the effects of XRCC1 Arg399Gln and Arg194Trp polymorphisms on cell viability, apoptosis and XRCC1 expression in cisplatin-sensitive A549 and cisplatin-resistant A549/DDP nonsmall cell lung cancer (NSCLC) cells. Plasmids carrying XRCC1 Arg399Gln and Arg194Trp were constructed and transfected into A549 and A549/DDP cells. RT–PCR, Western blot, MTT assay, and flow cytometry analysis were performed to assess cell viability, apoptosis, and XRCC1 expression. Compared to control cells,… More >
