Exposure to Sodium Hypochlorite or Cigarette Smoke Induces Lung Injury and Mechanical Impairment in Wistar Rats.
Inflammation
August 2022
Article Synopsis
- Pulmonary irritants like cigarette smoke and sodium hypochlorite can worsen lung health in cleaning workers, leading to changes in lung mechanics and inflammation in Wistar rats.
- Exposure to cigarette smoke alone caused increased airway inflammation and mucus production, while sodium hypochlorite elevated certain immune cell counts and inflammatory markers.
- Interestingly, when both irritants were present together, they increased mucus acidity and altered lung structure, suggesting a potential adaptive response that might protect the lungs from further damage despite reduced overall inflammation.
Intrauterine exposure to particulate matter (PM) has been associated with an increased risk of asthma development, which may differ by the age of asthma onset, sex, and pollutant concentration. To investigate the pulmonary effects of in utero exposure to concentrated urban ambient particles (CAPs) in response to house dust mite (HDM) sensitization in juvenile mice. Mice were exposed to CAPs (600 μg/m PM) during the gestational period.

During adolescence, transformations result in the development of autonomy. Adolescents with Down syndrome (ADS) have perceptual-cognitive limitations and few opportunities to acquire autonomy.

It has been recommended that medical students work as volunteers, undergo appropriate training, not undertake any activity beyond their level of competence, and receive continuous supervision and adequate personal protective equipment. However, the motivation of medical students must be evaluated to make volunteering a more evidence-based initiative.

Methods: To study the impact of sleep quality, daytime somnolence, and sleep deprivation on medical students, we analyzed data from a multicenter study with medical students in Brazil (22 medical schools, 1350 randomized medical students). We applied questionnaires of daytime sleepiness, quality of sleep, quality of life, anxiety and depression symptoms and perception of educational environment.
