Fluoride is emitted into the air not only through gas emissions but also from volcanic ash, leading to contact via inhalation. Therefore, the objective of the present study was to evaluate the cellular and biochemical responses in the A549 cell line after exposure to NaF (sodium fluoride) concentrations lower than those previously used in other studies to determine the impact on the lung epithelium. A549 cells were exposed to different concentrations (0.

Background Chronic obstructive pulmonary disease (COPD) is a progressive respiratory condition characterised by airflow limitation and reduced exercise capacity. The Six-Minute Walk Test (6MWT) and Two-Minute Walk Test (2MWT) are commonly used to assess functional exercise capacity in COPD patients. This study aims to evaluate the correlation between the distance covered in the 2MWT and 6MWT with spirometric indices (such as Forced Expiratory Volume in 1 second (FEV₁), Forced Vital Capacity (FVC), and FEV₁/FVC) in COPD patients.

This was an original article, mainly explored the effects of the first frozen-thawed embryo transfer (FET) time on pregnancy outcomes after progestin primed ovarian stimulation (PPOS) regimen. Our study implemented a retrospective analysis of 315 infertile patients who underwent in vitro fertilization and embryo transfer (IVF-ET) treatment from January 2021 to June 2023. Patients were divided into three groups based on their first FET time.

Purpose: Opioid misuse is increasingly recognized as a relevant problem among patients with cancer. However, the applicability of these concerns for patients with metastatic disease is complicated by shorter prognoses and greater symptom burden. This study aimed to investigate whether nonmedical opioid use (NMOU) was identified as contributing to opioid-related healthcare encounters among patients with metastatic cancer receiving long-term prescribing.
