A multidimensional feature fusion network based on MGSE and TAAC for video-based human action recognition.

With the maturity of intelligent technology such as human-computer interaction, human action recognition (HAR) technology has been widely used in virtual reality, video surveillance, and other fields. However, the current video-based HAR methods still cannot fully extract abstract action features, and there is still a lack of action collection and recognition for special personnel such as prisoners and elderly people living alone. To solve the above problems, this paper proposes a multidimensional feature fusion network, called P-MTSC3D, a parallel network based on context modeling and temporal adaptive attention module.

Deep Learning-Based Congestion Detection at Urban Intersections.

In this paper, a deep learning-based traffic state discrimination method is proposed to detect traffic congestion at urban intersections. The detection algorithm includes two parts, global speed detection and a traffic state discrimination algorithm. Firstly, the region of interest (ROI) is selected as the road intersection from the input image of the You Only Look Once (YOLO) v3 object detection algorithm for vehicle target detection.

Design and performance analysis of indoor cooperative IHDAF protocol-based spatial modulation-index modulation visible light communication system.

Spatial modulation (SM) has been employed in indoor visible light communication (VLC) systems because of its high data rate and low complexity transmission. However, the activated LED may have poor channel conditions in conventional SM VLC systems, which leads to significant performance degradation. In this paper, a cooperative incremental hybrid decode-amplify-forward (IHDAF) protocol-based SM-index modulation (SM-IM) VLC system is proposed.

Abrogating ClC-3 Inhibits LPS-induced Inflammation via Blocking the TLR4/NF-κB Pathway.

This study investigated the function of a chloride channel blocker, DIDS. Both in vitro and in vivo studies found that DIDS significantly inhibits lipopolysaccharide (LPS)-induced release of proin flammatory cytokines. Here, we show that DIDS inhibits LPS-induced inflammation, as shown by downregulation of inflammatory cytokines via inhibition of the TLR4/NF-κB pathway.

A novel fibrinogenase from Agkistrodon acutus venom protects against LPS-induced endotoxemia via regulating NF-κB pathway.

Context: Endotoxins including lipopolysaccharide (LPS) could cause endotoxemia which often results in excessive inflammation, organ dysfunction, sepsis, disseminated intravascular coagulation (DIC) or even death. Previously, a novel fibrinogenase (FII) showed protective effects on LPS-induced DIC via activating protein C and suppressing inflammatory cytokines.

Objective: To evaluate whether FII has protective effect on LPS-induced endotoxemia in mice and learn about the role of NF-κB pathway in TNF-α producing process.

Antagonism by salvianolic acid B of lipopolysaccharide-induced disseminated intravascular coagulation in rabbits.

The aim of the present study was to investigate the effects of salvianolic acid B on lipopolysaccharide (LPS)-induced disseminated intravascular coagulation (DIC) in rabbits. Continuous infusion of LPS was used to induce a DIC model in rabbits. Treatment with salvianolic acid B (1, 3 or 6 mg/kg) was started simultaneously with LPS infusion (0.

The ClC-3 chloride channel associated with microtubules is a target of paclitaxel in its induced-apoptosis.

Recent evidences show that cationic fluxes play a pivotal role in cell apoptosis. In this study, the roles of Cl(-) channels in paclitaxel-induced apoptosis were investigated in nasopharyngeal carcinoma CNE-2Z cells. Chloride current and apoptosis were induced by paclitaxel and inhibited by chloride channel blockers.

The correlation between calcaneus stiffness index calculated by QUS and total body BMD assessed by DXA in Chinese children and adolescents.

Few studies have shown comparison data between calcaneus stiffness index (SI) calculated by quantitative ultrasound (QUS) and bone mineral density (BMD) measured by dual-energy X-ray absorptiometry (DXA) in the Chinese population. This study was aimed to examine the correlations between calcaneus SI calculated by QUS and total body BMD and bone mineral content (BMC) measured by DXA in Chinese children and adolescents. We measured the total body BMD and BMC using Lunar Prodigy (GE Healthcare), and speed of sound (SOS), broadband ultrasound attenuation (BUA), and a calculated SI of the left os calcis using Lunar Achilles Express (GE Healthcare) in 392 healthy Chinese schoolchildren and adolescents aged 5-19 years.

[Role of chloride channels in gambogic acid-induced apoptosis of poorly differentiated nasopharyngeal carcinoma cells].

Objective: To investigate the role of chloride channels in the apoptosis of poorly differentiated nasopharyngeal carcinoma CNE-2Z cells induced by gambogic acid (GA).

Methods: MTT assay was applied to detect the proliferation of CNE-2Z cells after GA treatment, and the cell apoptosis was detected by Hoechst 33342 staining. Whole-cell patch clamp technique was employed to record GA-activated Cl(-) currents in the cells.

Lithium inhibits cell volume regulation by acting on chloride channels and modifies ultrastructures of the cell membrane in nasopharyngeal carcinoma cells.

Lithium salts have been used as a class of mood stabilizing agents to treat bipolar disorders for over a century. Although lithium is known to affect cell proliferation, apoptosis and migration, the underlying mechanisms have not been well-explored. Emerging evidence indicates that cell volume regulation and volume-activated chloride channels are involved in cell proliferation, apoptosis and migration.

[The effect of gastrodine on hepatitic cell line L02 injury induced by ethanol].

Aim: To explore the the effect of gastrodine on hepatitic cell line L02 injury induced by ethanol.

Methods: The growing L02 cells were treated with different concentrations of alcohol. For screening the proper concentration of alcohol, the proliferation of the cells were measured by MTT colorimetry.

[Construction of cyclin D1 recombinant plasmids and its expression in human nasopharyngeal carcinoma cells].

Objective: To construct the eukaryotic expression vectors of human cyclin D1 gene and express them in poorly differentiated nasopharyngeal carcinoma cells (CNE-2Z cells).

Chloride channels involve in hydrogen peroxide-induced apoptosis of PC12 cells.

Chloride channel activity is one of the critical factors responsible for cell apoptotic volume decrease (AVD). However, the roles of chloride channels in apoptosis have not been fully understood. In the current study, we assessed the role of chloride channels in hydrogen peroxide (H(2)O(2))-induced apoptosis of pheochromocytoma cells (PC12).
