Background: Increasing evidence has shown that elevated Thyroid stimulating hormone (TSH) levels are positively correlated with atherosclerosis (ATH) in patients with subclinical hypothyroidism (SCH). Some researchers found that the dysfunction of Endothelial Cells (ECs) in SCH plays an important role in the pathogenesis of ATH in SCH, but the association remains controversial.
Objectives: To determine the expression profiles of serum microRNAs critical to the function of Endothelial cells (ECs) may help reanalyze the possible mechanism underlying ATH in SCH and the association between ATH and SCH.
Methods: We used qRT-PCR to perform microRNA profiling and analysis in normal control subjects (NC), patients with SCH alone (SCH), patients with SCH and ATH (SCH+ATH), and patients with ATH without SCH (ATH).
Results: Both miR-221-3p and miR-222-3p showed a decreasing expression trend between the SCH and SCH+ATH groups. In addition, miR-126-3p and miR-150-5p showed a stepwise decrease from the NC to SCH groups and then to the SCH+ATH or ATH group. miR-21-5p was unregulated in the SCH, SCH+ATH, and ATH groups. Furthermore, elevated levels of miR-21-5p in SCH+ATH group were higher than SCH and ATH group. No differences were found in the levels of miR-150, miR-126, miR-221 and miR-222 between the ATH and the SCH+ATH subjects.
Conclusions: miR-21-5p may be involved in the atherosclerosis process in patients with SCH (SCH and SCH+ATH groups). miR-150-5p may be sensitive risk markers for predicting endothelial dysfunction in patients with ATH (ATH and SCH+ATH groups).

Background Subclinical hypothyroidism (SCH) in pregnancy poses serious maternal and fetal risks, including miscarriage, gestational diabetes, and neurodevelopmental impairment. Despite clear international guidelines like those from the American Thyroid Association (ATA), global practice remains inconsistent. In Saudi Arabia, where SCH prevalence among pregnant women is notably high (13%), there is limited national data on how closely physicians follow these guidelines.

Phosphorylation plays an important role in the activity of CDK2 and inhibitor binding, but the corresponding molecular mechanism is still insufficiently known. To address this gap, the current study innovatively integrates molecular dynamics (MD) simulations, deep learning (DL) techniques, and free energy landscape (FEL) analysis to systematically explore the action mechanisms of two inhibitors (SCH and CYC) when CDK2 is in a phosphorylated state and bound state of CyclinE. With the help of MD trajectory-based DL, key functional domains such as the loops L3 loop and L7 are successfully identified.

Background: Polycystic ovary syndrome (PCOS) is a prevalent endocrine and metabolic disorder affecting 5%-10% of reproductive-age women, accounting for 50%-70% of anovulatory infertility. Thyroid function, particularly the relationship between subclinical hypothyroidism (SCH) and PCOS, has garnered attention due to its potential impact on metabolic and reproductive health.
Methods: This study included 143 infertile women with PCOS diagnosed based on the Rotterdam criteria.

An Ag-functionalized structural color hydrogel (Ag-SCH) sensor is constructed for colorimetric detection of glutathione (GSH). The hydrogel is prepared by using the coordination of Ag and 1-vinylimidazole (1-VI) as cross-linking network. GSH acts as a competitive ligand to break the coordination between Ag and 1-VI, leading to the expansion and structural color change of the hydrogel.

Background: As students' use of mobile devices during school hours continues to increase, cyberbullying and online sexual harassment now occur during school hours, on school grounds via personal devices. Despite this growing reality, there is little knowledge about secondary school efforts to address it.
Methods: To understand what is needed to construct or reform policies that reflect students' online experiences, we used a mixed method approach to identify and analyze language (e.
