Many students compensate for lack of sleep through weekend catch-up sleep (CUS), however the degree of effectiveness is unclear. This study aimed to determine the association between weekend CUS and perceived stress in a large, school-based Korean adolescent sample. Data from the Korean Youth Risk Behavior Web-based Survey 2020 (KYRBWS) was used. The participants included 46,187 middle and high school students in the Republic of Korea who participated in self-administered questionnaire surveys. Weekend CUS was divided into four categories: 0 h, 0-1 h, 1-2 h, and ≥ 2 h. Odds ratios (ORs) with 95% confidence intervals (CIs) were derived using logistic regression analyses. We found that the risk of perceived stress decreased significantly in weekend CUS groups (0 < CUS < 1 [OR]: 0.879, [95% CI: 0.808-0.957]; 1 ≤ CUS < 2 [OR]: 0.852, [95% CI: 0.785-0.924]; 2 ≥ CUS [OR]: 0.836, [95% CI: 0.775-0.902]) compared to the non-CUS group after adjusting for several confounding variables. Furthermore, the higher CUS group tended to have a lower risk of perceived stress. However, in the Grade 12 participants, in both the unadjusted and adjusted models, the weekend CUS groups did not show a significant association with the risk of perceived stress.

However, studies on the role of Claudin-18.2 in pancreatic cancer are scarce, and a systematic exploration of its mechanisms of action in disease progression is missing. This research sought to reveal the detailed mechanisms by Claudin-18.2 impacts pancreatic cancer development and metastasis. Claudin-18.2 expression levels in pancreatic cancer were investigated through The Cancer Genome Atlas (TCGA) database, with subsequent validation by immunohistochemistry and quantitative reverse transcription polymerase chain reaction analysis. The potential regulatory transcription factors (TFs) for Claudin-18 were forecasted by the KnockTF database. Pearson's correlation was applied to ascertain the correlation between Claudin-18 and ZIC2, and the Molotool was utilized to analyze their potential binding sites. The TCGA database facilitated our analysis of ZIC2 expression levels within pancreatic cancer. Activation of the ERK signaling pathway was validated by western blot (WB). The colony formation assay evaluated cell proliferation, while the cell scratch and Transwell assays were used to determine cell migration and invasion abilities. WB was used to detect the expression of E-cadherin, N-cadherin and Vimentin associated with epithelial-mesenchymal transition. The ZIC2-Claudin-18.2 regulatory axis, via ERK1/2 signaling pathway activation, enhanced the malignant behaviors of pancreatic cancer. Claudin-18.2, when highly expressed in pancreatic cancer, facilitated tumor malignancy, primarily through activating the ERK1/2 signaling pathway. Additionally, ZIC2 was identified as an upstream regulatory molecule for Claudin-18.2.

RASSF8-AS1 was significantly upregulated not only in cartilage and synovium from OA patients, but also in IL-1β- or LPS-induced cells, compared to normal controls. A decrease in RASSF8-AS1 level increased the expression of chondrogenic markers, but reduced the expression of genes encoding matrix-degrading proteases, thereby reducing cell apoptosis.
