LINC00638/hsa-miR-29b-3p axis-mediated high expression of CDCA4 correlates with tumor immune infiltration and hepatocellular carcinoma progression.

Background: This study sought to explore the role of cell division cycle-associated protein 4 (CDCA4) in liver hepatocellular carcinoma (LIHC) patients.

Methods: The RNA-sequencing raw count data and the respective clinical information of 33 different LIHC cancer and normal tissues were collected from the Genotype Tissue Expression (GTEX) and The Cancer Genome Atlas (TCGA) databases. The expression of CDCA4 in LIHC was determined via the University of Alabama at Birmingham Cancer Data Analysis Portal (UALCAN) database.

Different Effect Mechanisms of Supercritical CO on the Shale Microscopic Structure.

To better understand how supercritical carbon dioxide (CO) enhances shale gas production, it is necessary to study the interaction of supercritical CO with shale and its impact on shale microstructure. The different mechanisms by which supercritical CO changes the shale pore structure were studied by X-ray diffraction analyses, scanning electron microscopy (SEM), nuclear magnetic resonance spectroscopy, and low-pressure nitrogen gas adsorption tests on shale samples before and after treatment with different pressures and gases (CO and Ar). The results showed that after treatment with CO, the mineral content of shale changed significantly, and in particular, the proportions of calcite and dolomite decreased.

Prenatal ultrasound diagnosis of chordee without hypospadias.

Chordee without hypospadias (CWH) is an extremely rare condition. Here, we describe a case of CWH diagnosed accurately on prenatal ultrasound at 25 weeks' gestation. Physical examination of the newborn confirmed the sonographic findings.
