LINC00882, transcriptionally activated by CEBP-β and post-transcriptionally stabilized by METTL14-mediated mA modification, exerts tumorigenesis by promoting PABPC1-mediated stabilization of ELK3 mRNA.

Breast cancer (BC) is the most common malignant tumor in women, and the majority of BC-related deaths are due to tumor metastasis. There is emerging evidence for the role of long noncoding RNAs (lncRNAs) in tumor progression. Nevertheless, lncRNAs that drive metastasis in patients with BC and the underlying mechanisms of lncRNAs are still largely elusive.

[Role and mechanism of platelet-derived growth factor BB in thrombocytosis in Kawasaki disease].

Objectives: To study the role and mechanism of platelet-derived growth factor BB (PDGF-BB) on platelet production in Kawasaki disease (KD) mice and human megakaryocytic Dami cells through and experiments.

Methods: ELISA was used to measure the expression of PDGF in the serum of 40 children with KD and 40 healthy children. C57BL/6 mice were used to establish a model of KD and were then randomly divided into a normal group, a KD group, and an imatinib group (30 mice in each group).

Extension of refocus depth range in digital holographic microscopy.

Digital holographic microscopy (DHM) suffers from a limited refocus depth range due to the employed microscope objective. The relationship between the refocus depth range of the DHM system and its optical parameters is studied theoretically and experimentally, and a method is proposed that combines wavefront coding with bicubic interpolation and extrapolation iteration to extend the refocus depth range. For obtaining a uniform point spread function on the refocus plane, a propagator kernel in numerical reconstruction is multiplied by a numerical logarithmic phase mask, and a deviation of the refocus distance is made.

High-Efficiency Automatic Recharging Mechanism for Cleaning Robot Using Multi-Sensor.

Cleaning robot has the highest penetration rate among the service robots. This paper proposes a high-efficiency mechanism for an intelligent cleaning robot automatically returns to charging in a short time when the power is insufficient. The proposed mechanism initially combines the robot's own motor encoder with neural network linear regression to calculate the moving distance and rotation angle for the location estimation of the robot itself.

Rational Design and Facial Synthesis of Li3V2(PO4)3@C Nanocomposites Using Carbon with Different Dimensions for Ultrahigh-Rate Lithium-Ion Batteries.

Li3V2(PO4)3 (LVP) particles dispersed in different inorganic carbons (LVP@C) have been successfully synthesized via an in situ synthesis method. The inorganic carbon materials with different dimensions including zero-dimensional Super P (SP) nanospheres, one-dimensional carbon nanotubes (CNTs), two-dimensional graphene nanosheets, and three-dimensional graphite particles. The effects of carbon dimensions on the structure, morphology, and electrochemical performance of LVP@C composites have been systematically investigated.

[Epidemiological investigation on the intermediate hosts of Paragonimus in Ninghai County of Zhejiang Province].

Freshwater crabs and snails were collected from Ninghai County in Zhejiang Province, and examined respectively for Paragonimus metacercariae and cercariae. Among 97 freshwater crabs found, the prevalence was 11.3% (11/97) with a mean intensity of 1 metacercariae per crab.

[Effects of simulated hypoxia on dielectric properties of mouse erythrocytes].

Aim: To explore the influence of simulated altitude hypoxia on dielectric properties of mouse erythrocytes.

Methods: Experimental animals were divided into the plain control group(control) and simulated altitude hypoxia group (altitude). The AC impedance of mouse erythrocytes was measured with the Agilent 4294A impedance analyzer, the influence of simulated altitude hypoxia on dielectric properties of mouse erythrocytes was observed by cell dielectric spectroscopy, Cole-Cole plots, loss factor spectrum, loss tangent spectrum, and curve fitting analysis of Cole-Cole equation.
