Four hundred and sixty-six references with 625 data reports were included in our study. The high frequency of ratio OC/EC for PM was observed in 3.92-5.93; PM in 1.08-3.08; PM, 2.08-4.08; PM in 2.70-4.70 and TSP in 2.66-4.66. The rank order of areas based on the pooled concentration of OC bound to PM was traffic (17.893 µg/m) > industrial (10.58 µg/m) > urban (7.696 µg/m) > rural (4.08 µg/m). The rank order of areas based on the pooled (mean) concentration of EC in PM was traffic (17.893 µg/m) > industrial (2.65 µg/m) > Urban (1.48 µg/m) > rural (1.06 µg/m). The pooled concentrations of OC and EC bound to PM in traffic areas were higher than in other areas. Therefore, it is recommended that monitoring and effectively reducing concentration plans are carried out, especially in traffic areas.

Background: In 1962, the idea emerged that medical students' tolerance of uncertainty could determine their specialty choice. While some studies supported this claim, others refuted it, often using independently developed instruments. We explored whether the reported link between specialty choice and uncertainty tolerance is more myth than evidence by employing established instruments to investigate whether specialty choice could be explained by variance in uncertainty tolerance.

Clustered data are common in practice. Clustering arises when subjects are measured repeatedly, or subjects are nested in groups (e.g.

Background: We aimed to examine the relationship between disease symptoms and disease phenotype in a large Canadian cohort of persons with Crohn's disease (CD).
Methods: Adults (n=1515) with CD from 14 Canadian centers participated in the Mind And Gut Interactions Cohort (MAGIC) between 2018 and 2023. Disease activity was measured using the 24-item IBD Symptom Inventory-Short-Form (IBDSI-SF).

Although multiple magnetic resonance imaging (MRI) indices are known to be sensitive to the noninvasive assessment of myelin integrity, their relative sensitivities have not been directly compared. This study aimed to identify the most sensitive MRI index for characterizing myelin composition in the spinal cord's gray matter (GM) and white matter (WM). MRI was performed on a deer's ex vivo cervical spinal cord.

: Obstructive Sleep Apnea (OSA) is a prevalent sleep disorder characterized by intermittent upper airway obstruction, leading to significant health consequences. Traditional diagnostic methods, such as polysomnography, are time-consuming and resource-intensive. : This study explores the potential of proton-transfer-reaction mass spectrometry (PTR-MS) in identifying volatile organic compound (VOC) biomarkers for the non-invasive detection of OSA.
