Acute ocular hypertension (AOH) is a condition found in acute glaucoma. The purpose of this study is to investigate the protective effect of Lycium barbarum polysaccharides (LBP) and its protective mechanisms in the AOH insult. LBP has been shown to exhibit neuroprotective effect in the chronic ocular hypertension (COH) experiments. AOH mouse model was(More)
PURPOSE Endothelin-1 (ET-1), synthesized in vascular endothelial cells, is a potent vasoconstrictor. ET-1-related vascular abnormality has been known to be important in the pathogenesis of glaucoma, especially in normal tension glaucoma. However, the long-term effect of increased vascular ET-1 on the retinal tissue is still unclear. METHODS The mice with(More)
In this paper, we describe a longitudinal user study with athletes using a cognitive training tool, equipped with an interactive pen interface, and think-aloud protocols. The aim is to verify whether cognitive load can be inferred directly from changes in geometric and temporal features of the pen trajectories. We compare trajectories across cognitive load(More)
The proliferation of vascular smooth muscle cells (VSMCs), remodeling of the vasculature, and the renin-angiotensin system (RAS) play important roles in the development of essential hypertension (EH), which is defined as high blood pressure (BP) in which secondary causes, such as renovascular disease, are absent. The calcium-sensing receptor (CaSR) is(More)
Photocrosslinked methacrylated hyaluronic acid (MeHA) hydrogels support chondrogenesis of encapsulated human mesenchymal stem cells (hMSCs). However, the covalent crosslinks formed via chain polymerization in these hydrogels are hydrolytically non-degradable and restrict cartilage matrix spatial distribution and cell spreading. Meanwhile, cells are known to(More)
BACKGROUND Information regarding association between cytomegalovirus (CMV) infection and essential hypertension (EH) risk is not consistent across studies. Therefore, we conducted a meta-analysis to investigate the association in detail. METHODS We comprehensively searched the published literature from the PubMed and Embase databases for any study(More)
Because of the non-linearity, time-delay existing in alkaline pefoxide mechanical pulp (APMP) wastewater treatment process, a fuzzy expert control strategy based on DCS was proposed in this paper. A feedforward and feedback plus PID control scheme based on expert system (ES) for dissolved oxygen (DO) value control was designed, by which different control(More)
An improved generalized predictive control (GPC) algorithm has been proposed in this paper. In order to cut off computation burden and get good performance of disturbance rejection, receding feedback correction mechanism is used to reject the disturbance instead of the traditional online identification mechanism. Furthermore, two factors are presented to(More)
The steam system is an important part of chemical utility system, but there are widespread phenomenon about lack of testing information, energy consumption configuration depend on given experience and wasting energy. So this paper puts forward a method about the steam pipe network system's status identification of different energy consumption based on the(More)
Typical soil crust surrounding the magnesite mining area can adversely affect local environment and inhibit the growth of crops. In order to study the forming mechanism of it, scanning electron microscopy (SEM), X-ray powder diffraction (XRD) and the adiabatic method were used to analyzed different layers of these typical crusts collected from magnesite(More)
