Abstract

The small cabbage white butterfly, , is a major agricultural pest of cruciferous crops and has been introduced to every continent except South America and Antarctica as a result of human activities. In an effort to reconstruct the near-global invasion history of , we developed a citizen science project, the "Pieris Project," and successfully amassed thousands of specimens from 32 countries worldwide. We then generated and analyzed nuclear (double-digest restriction site-associated DNA fragment procedure [ddRAD]) and mitochondrial DNA sequence data for these samples to reconstruct and compare different global invasion history scenarios. Our results bolster historical accounts of the global spread and timing of introductions. We provide molecular evidence supporting the hypothesis that the ongoing divergence of the European and Asian subspecies of (∼1,200 y B.P.) coincides with the diversification of brassicaceous crops and the development of human trade routes such as the Silk Route (Silk Road). The further spread of over the last ∼160 y was facilitated by human movement and trade, resulting in an almost linear series of at least 4 founding events, with each introduced population going through a severe bottleneck and serving as the source for the next introduction. Management efforts of this agricultural pest may need to consider the current existence of multiple genetically distinct populations. Finally, the international success of the Pieris Project demonstrates the power of the public to aid scientists in collections-based research addressing important questions in invasion biology, and in ecology and evolutionary biology more broadly.

Abstract

Based on the traditional Wifi positioning algorithm, the offline Wifi fingerprint database has a large number of redundant APs, which is easy to cause dimensionality disaster. Based on this situation, this paper proposes a Wifi positioning algorithm based on SVM-kmeans-ReliefF-SAE. First, the wifi fingerprint database is divided into building and floors by SVM algorithm, and the intra-floor region is divided by the K-means algorithm. Then the feature selection of the constructed Wifi fingerprint database is carried out. The redundant wifi offline fingerprint database of the divided area is removed by ReliefF algorithm, and the reduced offline fingerprint database is established. Finally constructing a deep neural network for the reduced wifi offline fingerprint database through the stack auto encoder. By pre-training the deep neural network, we can obtain a more accurate Wifi indoor positioning model. The experimental results by using the standard database UJIIndoor Loc show that the algorithm can effectively remove the redundant AP information in the offline Wifi fingerprint database and improve the positioning efficiency.

Abstract

The small cabbage white butterfly, Pieris rapae, is a major agricultural pest of cruciferous crops and has been introduced to every continent except South America and Antarctica as a result of human activities. In an effort to reconstruct the near-global invasion history of P. rapae, we developed a citizen science project, the “Pieris Project,” and successfully amassed thousands of specimens from 32 countries worldwide. We then generated and analyzed nuclear (double-digest restriction site-associated DNA fragment procedure [ddRAD]) and mitochondrial DNA sequence data for these samples to reconstruct and compare different global invasion history scenarios. Our results bolster historical accounts of the global spread and timing of P. rapae introductions. We provide molecular evidence supporting the hypothesis that the ongoing divergence of the European and Asian subspecies of P. rapae (∼1,200 y B.P.) coincides with the diversification of brassicaceous crops and the development of human trade routes such as the Silk Route (Silk Road). The further spread of P. rapae over the last ∼160 y was facilitated by human movement and trade, resulting in an almost linear series of at least 4 founding events, with each introduced population going through a severe bottleneck and serving as the source for the next introduction. Management efforts of this agricultural pest may need to consider the current existence of multiple genetically distinct populations. Finally, the international success of the Pieris Project demonstrates the power of the public to aid scientists in collections-based research addressing important questions in invasion biology, and in ecology and evolutionary biology more broadly.

177. Is olaparib cost effective in metastatic castration-resistant prostate cancer patients with at least one favorable gene mutation in BRCA1, BRCA2or ATM?

Author

Li, Yiyuan, Lin, Shen, Zhong, Lixian, Luo, Shaohong, Huang, Xiaoting, Huang, Xiaojia, Dong, Liangliang, Xu, Xiongwei, and Weng, Xiuhua

Abstract

Aim:To compare the cost–effectiveness of olaparib versus control treatment in metastatic castration-resistant prostate cancer patients with at least one gene mutation in BRCA1, BRCA2or ATMfrom the US payer perspective. Methods:A Markov model was constructed to assess the quality-adjusted life years (QALYs) and incremental cost–effectiveness ratios. Sensitivity analyses and scenario analyses were conducted to explore the impact of uncertainties. Results:The base-case result indicated that, for patients with specific gene mutations, olaparib gained 1.26 QALYs and USD$157,732 total cost. Compared with control treatment, the incremental cost–effectiveness ratio of olaparib was USD$248,248/QALY. The price of olaparib was the most influential parameter. Conclusion:Olaparib is not cost effective in comparison with control treatment in metastatic castration-resistant prostate cancer patients with specific gene mutations.

Abstract

Objective: To explore the effectiveness of the insulin‐like growth factor 1 receptor (IGF‐1R)/PI3K/AKT pathway in promoting the synthesis of the auricular chondrocyte extracellular matrix (ECM) using concentrated growth factor (CGF). Methods: Chondrocytes isolated from the remnant auricular cartilage of microtia patients were randomly divided into different experimental and control groups, then stimulated with a reagent. IGF‐1 released by CGF was quantified by enzyme‐linked immunosorbent assay. Glycosaminoglycan (GAG), proteoglycan, and type II collagen (COLAII) were examined by histological and immunohistological analysis. Expression levels of IGF‐1R, pIGF‐1R, PI3K, pPI3K, AKT, pAKT, COLAII, and Aggrecan were detected by western blot analysis technique and gene expression was tested by real‐time polymerase chain reaction. Results: CGF significantly stimulated the synthesis of COLAII and Aggrecan and increased the phosphorylation levels of IGF‐1R, PI3K, and AKT. Small interfering RNA IGF‐1 blocked ECM synthesis, COLAII and Aggrecan gene expression, and IGF‐1R/PI3K/AKT activation. Inhibitor AG1024 and LY294002 significantly inhibited ECM synthesis and the phosphorylation of IGF‐1R, PI3K, and AKT. Conclusion: CGF‐released IGF‐1 stimulates the synthesis of the auricular chondrocyte ECM via the IGF‐1R/PI3K/AKT signaling pathway. [ABSTRACT FROM AUTHOR]

Abstract

A 51-year-old male presented with chest pain after swallowing a fishbone and was hospitalized. Gastroscopy did not reveal any signs of a foreign body, but a chest CT scan showed a sharp object that had penetrated the thoracic aorta. The patient was diagnosed with an aorto-oesophageal fistula and underwent emergency surgery to repair the injured aorta. Further imaging indicated that a fishbone had also penetrated the hepatic artery, and the patient underwent another surgery to repair the artery. The patient recovered well without complications.
