This study aimed to explore the impact of atmospheric pollutants on incidence tuberculosis (TB), and provide new ideas for prevention control TB in future.It explored relationship between air meteorological factors, as well heating through Spearman correlation analysis rank sum test. Additionally, it analyzed using general additive model. Statistical results at p<0.05 level were considered significant.Three months after exposure (PM2.5, SO2, NO2, CO) increased. However, increased 9 PM10. The...

Double-arm picking robots are widely used in agricultural production for their high collaborative efficiency. While picking, area planning and collision detection between the mechanical arms is a crucial challenge double-arm robot, which needs to establish collision-free path fruit picking. In this study, we developed cooperation method robotic of kiwifruit. Firstly, problem dividing was simplified into multiple traveling salesmen (MTSP) be solved. The sequence each arm formulated by...

Abstract The pea aphid, Acyrthosiphon pisum , has an incomplete immune system compared to those of other insect species; some conserved components and pathways in species are missing its genome. As a core component the system, prophenoloxidase (PPO) genes retained aphid. Early studies have also shown presence phenoloxidase activity specific tissues or cells aphid suggested involvement response challenges. In this study, we knocked down expression PPO using double‐stranded RNA‐based...

Kiwifruit harvesting with robotics can be troublesome due to the clustering feature. The gripper of end effector will easily cause unstable fruit grasping, or bending and separation action interfere neighboring because an inappropriate grasping angle, which further affect success rate. Therefore, predicting correct angle for each guide safely approach, grasp, bend separate fruit. To improve rate rate, this study proposed a detection method kiwifruit robot based on GG-CNN2. Based vertical...

Abstract The growth of endometrial stromal cells (ESCs) at implantation sites may be a potential factor affecting the success rate embryo implantation. Incremental proofs demonstrated that ncRNAs (e.g. miRNAs, lncRNAs and circRNAs) were involved in various biological procedures, including proliferation apoptosis. In this study, role miR‐100‐5p on apoptosis goat ESCs vitro vivo was determined. mRNA expression significantly inhibited receptive phase (RE) rather than pre‐receptive (PE)....

To address the issue of low positioning accuracy mobile robots in trellis kiwifruit orchards with weak signal environments, this study investigated an outdoor integrated method based on ultra-wideband (UWB), light detection and ranging (LiDAR), odometry (ODOM). Firstly, a dynamic error correction strategy using Kalman filter (KF) was proposed to enhance UWB. Secondly, particle algorithm (PF) employed fuse UWB/ODOM/LiDAR measurements, resulting extended (EKF) measurement value. Meanwhile,...

Epidemiological studies show a strong correlation between air pollution and fetal growth restriction (FGR), but existing results are controversial due to inherent limitations, such as causality of specific pollutants, developmental origin, maternal–fetal transmission. To address this controversy, we first conducted retrospective analysis 28,796 newborns revealed that maternal nitrogen dioxide (NO 2 ) exposure during the second trimester was positively associated with FGR, an adjusted odds...

Nutrients can greatly affect host immune defenses against infection. Possessing a simple system, insects have been widely used as models to address the relationships between nutrition and immunity. The effects of high versus low protein-to-carbohydrate ratio (P:C) diets on insect responses vary in different studies. To reveal dietary manipulation polyphagous agricultural pest oriental armyworm, we examined gene expression, phenoloxidase (PO) activity, phagocytosis investigate traits...

Homocysteine (Hcy) and its metabolically related aminothiols cysteine (Cys), cysteinylglycine (CysGly), glutathione (GSH) play important roles in the pathogenesis of uremia. Most these exist plasma as disulphide mixed forms. A new, simple, sensitive reliable precolumn derivatization HPLC method, with fluorescence detection, for determination four kinds aminothiols, including total, free reduced fractions, simultaneously was established validated. After a simple using N-(1-pyrenyl) maleimide...

To ensure that farmers can access high-quality seeds, it is essential to find a simple, rapid and accurate method assess seed purity. In recent years, heterosis in chieh-qua has been widely applied production. Using the whole genome sequence of chieh-qua, we designed simple repeat (SSR) primers specific for chieh-qua. The parental lines nine hybrids were screened using 200 SSR primers, seven which exhibited polymorphisms. bands clear, stable reproducible. We found dominant co-dominant...
