Impact of a novel prognostic model on allogeneic hematopoietic stem cell transplantation outcomes in patients with CMML

Jian‐Ying Zhou, Song Wang, Hai‐Long Yuan, Ya‐Jing Xu, more

American Journal of Hematology > 98 > 9 > 1394 - 1406

Chronic myelomonocytic leukemia (CMML) is a clonal hematopoietic stem cell malignancy, and allogeneic hematopoietic stem cell transplantation (allo‐HSCT) is the only curable treatment. The outcomes after transplant are influenced by both disease characteristics and patient comorbidities. To develop a novel prognostic model to predict the post‐transplant survival of CMML patients, we identified risk...

Shuming Chen, Jintao Wang, Ning Jiang, Zhenyu Wang, more

physica status solidi (RRL) – Rapid Research Letters > 17 > 5 > n/a - n/a

Perovskite solar cells (PSCs) have broad application prospects in the field of renewable energy. The photovoltaic performance and long‐term stability of PSCs are important factors for the industrialization of PSCs. Passivation of perovskite films by antioxidants is an effective approach to not only reduce the density of defect states but also improve the environmental stability of the device. Herein,...

Advanced Materials > 35 > 13 > n/a - n/a

Manual intervention in the self‐organization of soft matter to obtain a desired superstructure is a complex but significant project. Specifically, optical components made fully or partially from reconfigurable and stimuli‐responsive soft materials, referred to as soft photonics, are poised to form versatile platforms in various areas; however, a limited scale, narrow spectral adaptability, and poor...

Source Lithology and Magmatic Processes Recorded in the Mineral of Basalts from the Parece Vela Basin

Long YUAN, Quanshu YAN

Acta Geologica Sinica ‐ English Edition > 96 > 6 > 1991 - 2006

Since the Early Cenozoic, the Philippine Sea Plate (PSP) has undergone a complex tectonic evolution. During this period the Parece Vela Basin (PVB) was formed by seafloor spreading in the back‐arc region of the proto‐Izu‐Bonin‐Mariana (IBM) arc. However, until now, studies of the geological, geophysical, and tectonic evolution of the PVB have been rare. In this study, we obtained in situ trace element...

Shishuai Yan, Quanshu Yan, Xuefa Shi, Long Yuan, more

Geological Journal > 57 > 10 > 4074 - 4089

The Yap trench‐island arc system, where three tectonic plates (i.e., the Philippine Sea Plate, Pacific Plate, and Caroline Plate) interact, has undergone a relatively complicated geological evolution. East of the system, the Caroline Plateau are being subducted, and the plateau has been rifted into east and west Caroline ridges by the development of the Sorol Trough. However, until now, knowledge...

Nurul Aida Mohd Mortar, Mohd Mustafa Al Bakri Abdullah, Kamarudin Hussin, Rafiza Abdul Razak, more

Archives of Metallurgy and Materials > 2022 > Vol. 67, iss. 4 > 1349--1354

This paper details a finite element analysis of the behaviour of Si-Al geopolymer concrete beam reinforced steel bar under an impulsive load and hyper velocity speed up to 1 km/s created by an air blast explosion. The initial torsion stiffness and ultimate torsion strength of the beam increased with increasing compressive strength and decreasing stirrup ratio. The study involves building a finite...

Genome‐wide gene expression profiles of the pea aphid (Acyrthosiphon pisum) under cold temperatures provide insights into body color variation

Li Zhang, Zhou‐Rui Zhang, Yong‐Qiang Zheng, Li‐Jun Zhang, more

Archives of Insect Biochemistry and Physiology > 108 > 1 > n/a - n/a

Cold temperatures are one of the factors influencing color polymorphisms in Acyrthosiphon pisum, resulting in a change from a red to greenish color. Here we characterized gene expression profiles of A. pisum under different low temperatures (1°C, 4°C, 8°C, and 14°C) and durations (3, 6, 12, and 24 h). The number of differentially expressed genes (DEGs) increased as temperatures decreased and time...

Jahn–Teller Disproportionation Induced Exfoliation of Unit‐Cell Scale ϵ‐MnO₂

Yilan Jiang, Long Yuan, Xiyang Wang, Wei Zhang, more

Angewandte Chemie > 132 > 50 > 22848 - 22855

Exfoliation of non‐layered (structurally) bulk materials at the nanoscale is challenging because of the strong chemical bonds in the lattice, as opposed to the weak van der Waals (vdW) interactions in layered materials. We propose a top‐down method to exfoliate ϵ‐MnO₂ nanosheets in a family of charge‐ordered La_1−xAE_xMnO₃ (AE=Ca, Sr, Ba) perovskites, taking advantage of the Jahn–Teller disproportionation...

Comparative transcriptomic analysis of fireflies (Coleoptera: Lampyridae) to explore the molecular adaptations to fresh water

Qi‐Lin Zhang, Hong‐Wei Li, Zhi‐Xiang Dong, Xiao‐Jie Yang, more

Molecular Ecology > 29 > 14 > 2676 - 2691

Aquatic insects are well adapted to freshwater environments, but the molecular basis of these adaptations remains largely unknown. Most firefly species (Coleoptera: Lampyridae) are terrestrial, but the larvae of several species are aquatic. Here, larval and adult transcriptomes from Aquatica leii (freshwater) and Lychnuris praetexta (terrestrial) were generated to test whether the genes associated...

Zhijun Dong, Aissa Bouaissi, Xianfeng Wang, Yijiao Huang, more

Advanced Engineering Materials > 21 > 11 > n/a - n/a

Reducing the emission of CO₂ into the atmosphere is a challenge due to rapid industrial development, particularly in developing countries. Ordinary Portland cement (OPC) is the second‐most‐consumed material just after water. It is estimated that the production of one ton OPC generates ≈0.87 ton CO₂. Geopolymers are considered as the sustainable materials that possess similar or even better mechanical...

Kun Gui, Cong-long Yuan, Shan-shan Zhang, Jian-dong Wang, more

SID Symposium Digest of Technical Papers > 50 > S1 > 632 - 634

Wide viewing angle is a critical optical specification for liquid crystal displays (LCDs), particularly in automotive displays. We proposed an optimized compensation film which consists of a biaxial positive B film and a negative B film to improve the viewing angle of LCDs with Super Fine TFT (SFT) mode. Under optimized retardations, minimum contrast ratio in area A can tremendously reach 0.59 times...

An immunosuppressive peptide from the horsefly inhibits inflammation by repressing macrophage maturation and phagocytosis

Ran Chen, Long Yuan, Nengqi Cao, Pengpeng Li, more

Journal of Cellular Biochemistry > 120 > 8 > 14116 - 14126

Ectoparasites repress host immune responses while they obtain nutrition from their hosts. Understanding the immunosuppressive mechanisms between ectoparasites and their hosts will provide new strategies to develop potential immunosuppressive drugs against immune disorder diseases. Previously, we have discovered that a small peptide, immunoregulin HA, from the horsefly (Hybomitra atriperoides) may...

Computational and Applied Mathematics > 2019 > 38 > 3 > 1-29

In this paper, we develop a plane wave discontinuous Galerkin method combined with local spectral element method for the elastic wave propagation in two and three space dimensions. We derive the error estimates of the approximation solutions in the mesh-dependent norm and the mesh-independent norm. Some dependence of the error bounds on the orders q of local spectral elements and the number p of plane...

Mengna Duan, Xiaofeng Wu, Long Yuan, Zhiying Zhang, more

Chemical Research in Chinese Universities > 2019 > 35 > 4 > 686-692

Compared with the traditional dental implant, TixOs® manufactured by direct laser metal forming(DLMF) technology exhibits improved capability for bone osteointegration due to its porous surface structure, and has achieved remarkable clinical effect. However, like the traditional titanium and other alloyed implants, the porous titanium implant TixOs® also has relatively weak bioactivity. To address...
