Abstract BACKGROUND Cropland in Yangtze River Delta has declined drastically since economic reforms in 1978 that led to rapid economic development. Such cropland loss due to population growth has led to a decline in grain production. This study aimed at analyzing the impact of land use changes on grain production. To achieve this, the spatiotemporal dynamics of cropland during 1980–2010 were analyzed. Irrigation and soil fertility data were used as additional lines of evidence. RESULTS Cropland ...

Dysregulation of autophagy in endothelial cells plays a vital role in cardiovascular dysfunction and atherosclerosis. Accumulating evidence shows that miRNAs regulate autophagy in various cell types by targeting autophagy-related genes. In the present study, we found that a co-culture of human umbilical vein endothelial cells (HUVECs) with human aortic smooth muscle cells (HAoSMCs) inhibited autophagy activity in HUVECs. Furthermore, we isolated exosomes secreted by HAoSMCs, and confirmed that the ...

Myocardium regeneration in adult mammals is very limited, but has enormous therapeutic potentials. However, we are far from complete understanding the cellular and molecular mechanisms by which heart tissue can regenerate. The full functional ability of amphibians to regenerate makes them powerful animal models for elucidating how damaged mature organs are naturally reconstituted in an adult organism. Like other amphibians, such as newts and axolotls, adult Xenopus displays high regenerative capacity ...

The anisotropic removal behavior of single crystal calcium fluoride (CaF2) severely restricts the improvement of surface quality in ultra-precision machining. In this study, the anisotropic mechanical removal of CaF2 material was investigated quantitatively along various crystal orientations on CaF2(111), (110), and (001) surfaces by a conical diamond tip. With the increase of load, the wear of CaF2 material has an elastic–ductile–brittle transition, and the corresponding critical load and wear depth ...

Aim: This prospective study aimed to evaluate the relationship between the ratio of C-reactive protein-to-prealbumin (CRP/PAB) and clinical outcomes in medical intensive care unit patients. Materials & methods: All 240 consecutive adult patients were enrolled in this study with demographic and clinical features collected. Results: Compared with patients belonging to the CRP/PAB ≤0.24 group, hospital mortality and the total length of stay in hospital (TLSH) were significantly increased in patients in ...

Metasurface optics is a promising candidate for realizing the next generation of miniaturized optical components. Unlike refractive optics, these devices modify light over a wavelength-scale thickness, changing the phase, amplitude, and polarization. This review details recent developments and state-of-the-art metasurfaces realized using silicon nitride. We emphasize this material as to date it has the lowest refractive index with which metasurfaces have been experimentally demonstrated. The wide ...

Arabidopsis roots sense the moisture gradient in soils and grow toward an area with higher water potential – a process called hydrotropism. Our previous study has shown that the apoplastic proton extrusion in root tips is influenced by brassinosteroids (BRs) receptor BR-INSENSITIVE1 (BRI1) and is crucial for hydrotropic response in Arabidopsis. Here we show that BRI1 interacts directly not only with Arabidopsis plasma membrane H+-ATPase 2 (AHA2) but also with Arabidopsis plasma membrane H+-ATPase 7 (AHA7). ...

Nuclear factor (erythroid-derived 2)-like 2 (Nrf2) was closely involved in doxorubicin- (DOX-) induced cardiotoxicity. MicroRNA-200a (miR-200a) could target Keap1 mRNA and promote degradation of Keap1 mRNA, resulting in Nrf2 activation. However, the role of miR-200a in DOX-related cardiotoxicity remained unclear. Our study is aimed at investigating the effect of miR-200a on DOX-induced cardiotoxicity in mice. For cardiotropic expression, male mice received an injection of an adeno-associated virus 9 ( ...

Human activities do not only change the land use/land cover (LULC), but also release a large amount of anthropogenic heat through intensive activities above ground, which drives the formation of urban heat island (UHI). This study used the Nanjing metropolitan area as the research area and taken 2017 as the observation time and chosen land surface characteristic parameters, point of interest (POI) density and urban functional area data to quantify the driving mechanism of human activities at a grid ...

Reducing torque ripples in a permanent magnet (PM) synchronous machine (PMSM) system has been an essential requirement in some high-performance applications. To suppress the torque ripples caused by time harmonics and spatial harmonics, an approach based on injecting minimum harmonic currents is proposed here. The proposed method extracts torque ripples from speed fluctuations, and the gradient descent optimisation (GDO) is utilised to determine the injected harmonic currents which are the commands ...

Metasurface optics have demonstrated vast potential for implementing traditional optical components in an ultracompact and lightweight form factor. Metasurfaces, however, suffer from severe chromatic aberrations, posing serious limitations on their practical use. Existing approaches for circumventing this involving dispersion engineering are limited to small apertures and often entail multiple scatterers per unit cell with small feature sizes. Here, we present an alternative technique to mitigate ...
