Groundwater serves as an indispensable resource for freshwater, but its quality has experienced a notable decline over recent decades. Spatial prediction of groundwater quality (GWQ) can effectively assist managers in groundwater remediation, management, and risk control. Based on the traditional intrinsic groundwater vulnerability (IGV) model (DRASTIC) and three vegetation (V) indicators (NDVI, EVI, and kNDVI) and four human activity (H) indicators (land use, GDP, urbanization index, and nighttime light), we constructed four models for GWQ spatial prediction in the Jianghan Plain (JHP), namely DRASTI, DRASTIH, DRASTIV, and DRASTIVH, excluding the conductivity (C) indicator due to its uniformly low values.

By employing DCE as the solvent, we obtained a variety of chiral hydrindanes containing an all-carbon quaternary carbon center and a tertiary carbon chiral center in good yields with excellent enantioselectivities. With alcohols as the solvent, the valuable chiral hydrindanes with one quaternary stereocenter and two tertiary centers were constructed with a high level of enantioinduction.

Objective: This study aimed to investigate the malocclusion associated with TMJ ADD and CR in adolescents.
Methods: This cross-sectional study included a clinical examination of adolescent patients aged 11-19 years.
A novel iridium-catalyzed [3 + 2] annulation of naphthylamines and α-diazocarbonyl compounds was developed for the rapid assembly of densely functionalized indoles. This new catalytic process represents the first example of a cascade intramolecular nucleophilic cyclization by the N-H insertion of amines. Various naphthylamines and α-diazocarbonyl compounds could be obtained in high yields with excellent functional group tolerance.

The aim of the study was to systematically evaluate the main factors associated with lung cancer incidence in China and provide reference for developing successful lung cancer interventions and accelerating progress against cancer. All publications related to the influencing factors of lung cancer incidence were retrieved from four databases from their date of inception through September 2022. Eight Medical Subject Headings and corresponding keywords were utilized to identify eligible trials in China National Knowledge Infrastructure (CNKI), Wanfang Database, Chinese Scientific Journals Database (VIP), and China Biology Medicine Database (CBM).

However, excessive and uncontrolled use has also caused some adolescents to develop short-form video addiction (SFVA). Although parental phubbing has been shown to be a risk factor for SFVA in adolescents, its intermediate mechanisms, particularly the emotional mediation mechanisms, remain unclear.
View Article and Find Full Text PDFTemporomandibular joint osteoarthritis (TMJOA) is a commonly encountered degenerative joint disease in oral and maxillofacial surgery. Recent studies have shown that the excessive unbalanced activation of Wnt/β-catenin signaling is connected with the pathogenesis of TMJOA and due to the inability to inhibit the over-activated Wnt pathway, while Wnt16-deficient mice has a more severe Knee OA. However, the efficacy of direct intra-TMJ injection of Wnt16 for the relief of TMJOA is still not directly confirmed.
