High-Efficiency Clustering Routing Protocol in AUV-Assisted Underwater Sensor Networks.

Currently, underwater sensor networks are extensively applied for environmental monitoring, disaster prediction, etc. Nevertheless, owing to the complicacy of the underwater environment, the limited energy of underwater sensor nodes, and the high latency of hydroacoustic channels, the energy-efficient operation of underwater sensor networks has become an important challenge. In this paper, a high-efficiency clustering routing protocol in AUV-assisted underwater sensor networks (HECRA) is proposed to address the energy limitations and low data transmission reliability in underwater sensor networks.

Epidemiological and clinical characteristics of open globe injuries in Southwest China.

Background: Open globe injuries (OGIs) are one of the leading causes of monocular vision loss, and the clinical characteristics of OGIs are region specific. The features and patterns of OGIs in Southwest China are poorly known and not well studied. Our study aimed to review the epidemiological and clinical characteristics of patients hospitalized for OGIs in Southwest China.

Path planning for mobile robots in complex environments based on improved ant colony algorithm.

Aiming at the problems of the basic ant colony algorithm in path planning, such as long convergence time, poor global path quality and not being suitable for dynamic environments and unknown environments, this paper proposes a path planning method for mobile robots in complex environments based on an improved ant colony (CBIACO) algorithm. First, a new probability transfer function is designed for an ant colony algorithm, the weights of each component in the function are adaptively adjusted to optimize the convergence speed of the algorithm, and the global path is re-optimized by using the detection and optimization mechanism of diagonal obstacles. Second, a new unknown environment path exploration strategy (UPES) is designed to solve the problem of poor path exploration ability of the ant colony algorithm in unknown environment.

Prevention of quality characteristic decline in freeze-thawed cultured large yellow croaker () using flammulina velutipes polysaccharide.

To investigate the cryoprotective effect of flammulina velutipes polysaccharide (FVP) on the quality characteristics in freeze-thawed cultured large yellow croaker, 0.050%, 0.075%, and 0.

Flammulina velutipes polysaccharide improves the water-holding capacity in the dorsal muscle of freeze-thawed cultured large yellow croaker (Larimichthys crocea).

To investigate the effect of Flammulina velutipes polysaccharide (FVP) on the water-holding capacity (WHC) in the dorsal muscle of freeze-thawed large yellow croaker, fresh fish were treated with FVP, commercial cryoprotectant (CC), and distilled water before freezing. The water-holding capacity (WHC) and related influencing factors were analyzed. The results showed that FVP was able to effectively improve the WHC by reducing thawing loss and cooking loss, and the effect was similar to that of the CC group.

Microbial Communities and Flavor Compounds during the Fermentation of Traditional Hong Qu Glutinous Rice Wine.

As a traditional Chinese rice wine, Hong Qu glutinous rice wine (HQW) is popular among consumers due to its unique flavor. However, its quality changes during fermentation, and the potential relationships between flavor and microbes have not been systematically researched. In this work, physicochemical properties (pH, total sugar, alcohol, amino acid nitrogen), flavor compounds (organic acids, free amino acids, and volatile compounds), and microbial communities were investigated.

mTORC1 Up-Regulates GP73 to Promote Proliferation and Migration of Hepatocellular Carcinoma Cells and Growth of Xenograft Tumors in Mice.

Background & Aims: Levels of the Golgi protein 73 (GP73) increase during development of hepatocellular carcinoma (HCC); GP73 is a serum marker for HCC. However, little is known about the mechanisms or effects of GP73 during hepatic carcinogenesis.

Methods: GP73 was overexpressed from a retroviral vector in HepG2 cells, which were analyzed in proliferation and migration assays.

[Efficacy of combination treatment of the inhibitor of phosphatidyl inositol-3-kinase/protein kinase B pathway BEZ235 and the inhibitor of extracellular regulated protein kinase/mitogen-activated protein kinase pathway U0126 in a tumor cell model].

Objective: To study the inhibitory effect of the dual usage of BEZ235 and U0126, the inhibitor of phosphatidyl inositol-3-kinase/protein kinase B pathway and extracellular regulated proteinkinase/mitogen-activated protein kinase pathway, respectively, on cell proliferation.

Methods: Phosphatase and tensin homolog knockout mouse embryonic fibroblast (PTEN-/-MEF) cell lines were used as the cellular model for malignant tumors. BEZ235, the dual inhibitor of phosphatidyl inositol-3-kinase and mammalian target of rapamycin, and U0126, the inhibitor of mitogen-activated protein kinase were used to treat the cells individually and in a combination manner.
