Supplementary material from \"Hoxa9/meis1-transgenic zebrafish develops acute myeloid leukaemia-like disease with rapid onset and high penetrance\"

Wei Wang, Hongji Li, Mengling Huang, Xue Wang, Wei Li, Xiaoqing Qian & Lili Jing
HOXA9 and MEIS1 are co-expressed in over 50% of acute myeloid leukaemia (AML) and play essential roles in leukemogenesis, but the mechanisms involved are poorly understood. Diverse animal models offer valuable tools to recapitulate different aspects of AML and link in vitro studies to clinical trials. We generated a double transgenic zebrafish that enables hoxa9 overexpression in blood cells under the draculin (drl) regulatory element and an inducible expression of meis1 through a heat shock...

In order to improve the output power of solar-pumped single-crystal fiber (SCF) lasers, a novel solar concentrating system is proposed, which consists of a parabolic mirror, a 3D-CPC, and a hollow-core reflector. By ray tracing with TracePro, influence of the fiber’s diameter and the hollow reflector’s shape on the solar absorption efficiency is theoretically investigated. A typical Nd:YAG SCF with a core-diameter of 1 mm, length of 150 mm and doping concentration of 1 at.%...

NUPR1 contributes to radiation resistance by maintaining ROS homeostasis via AhR/CYP signal axis in hepatocellular carcinoma

Yizhi Zhan, Zhanqiao Zhang, Yuechen Liu, Yuan Fang, Yuwen Xie, Yilin Zheng, Guoxin Li, Li Liang & Yi Ding
Abstract Background Radiotherapy (RT) is one of the major therapeutic approaches to hepatocellular carcinoma (HCC). Ionizing radiation (IR) inducing the generation of reactive oxygen species (ROS) leads to a promising antitumor effect. However, the dysregulation of the redox system often causes radioresistance and impairs the efficacy of RT. Increasing evidence indicates that nuclear protein 1 (NUPR1) plays a critical role in redox reactions. In this study, we aim to explore the role of NUPR1 in...

Results 1) differentially expressed protein-coding genes, miRNAs, and long non-coding RNAs in atm mutated flies were identified at physiological condition and...

Compressing and interpreting word embeddings with latent space regularization and interactive semantics probing

Haoyu Li, Junpeng Wang, Yan Zheng, Liang Wang, Wei Zhang & Han-Wei Shen
Word embedding, a high-dimensional (HD) numerical representation of words generated by machine learning models, has been used for different natural language processing tasks, for example, translation between two languages. Recently, there has been an increasing trend of transforming the HD embeddings into a latent space (e.g. via autoencoders) for further tasks, exploiting various merits the latent representations could bring. To preserve the embeddings’ quality, these works often map the embeddings into an even higher-dimensional latent...

Abstract Background Little is known about the effects of maintaining healthy sleep patterns on frailty transitions. Methods Based on 23,847 Chinese adults aged 30–79 in a prospective cohort study, we examined the associations between sleep patterns and frailty transitions. Healthy sleep patterns included sleep duration at 7 or 8 h/d, without insomnia disorder, and no snoring. Participants who persisted with a healthy sleep pattern in both surveys were defined as maintaining a healthy sleep pattern...

Fei Liu, Weiguang Shi, Tianbao Liu, Wei Li, Liang Sun, Xiangbin Liu, Changming Zhao, Benxian Li, Sunhua Deng, Zhaohui Dong, Chengwu Xu, Xiaofei Fu & Xiuling Yan
Oil shale kerogen is a kind of composite nature of fossil energy polymer. Kerogen pyrolysis is a feasible and alternative strategy to produce fossil fuels from shales. However, the disadvantages including the high energy consumption, the high cost, and the low hydrocarbon conversion, significantly hinder the development and utilization of unconventional hydrocarbon resources. Herein, the hexagonal crystal structural layered double hydroxides (LDHs) with the Ni/Fe ratio of 5.64:2.36 is proposed as pyrolysis catalyst to improve...
