During international air travel individuals stay in a closed environment which might lead to a risk of transmission of respiratory infectious diseases such as tuberculosis carried by infectious travellers. Tracing exposed passengers requires international cooperation and assistance from relevant authorities. We describe an investigation among fellow passengers to a traveller with sputum positive pulmonary tuberculosis.

Photothermal reactions, involving both photochemical and thermal reaction steps, are the most abundant sequences in photochemistry. The derivation of their rate laws is standardized, but the integration of these rate laws has not yet been achieved. Indeed, the field still lacks integrated rate laws for the description of these reactions' behavior and/or identification of their reaction order.

Oxygen controls most metazoan metabolism, yet in mammals, tissue O levels vary widely. While extensive research has explored cellular responses to hypoxia, understanding how cells respond to physiologically high O levels remains uncertain. To address this problem, we investigated respiratory epithelia as their contact with air exposes them to some of the highest O levels in the body.

Bisphenol A (BPA) is a monomer of plastic that can leach into water from scratched containers when used for an extended period. Arsenic (As) is an environmental toxicant, and people are exposed to both arsenic and BPA through drinking water and through scratched plastic containers used in contaminated areas. However, the combined effects of As and BPA on locomotor performance and neurobehavioral changes are yet to be investigated.

Background: Trace element and metal exposure is closely related to the occurrence of chronic diseases, particularly affecting blood pressure and blood glucose. Current studies suggest that heavy metal exposure is a risk factor for hypertension and diabetes. Aluminum can enter the human body through daily life and occupational exposure from food, environment, drugs, and other sources, affecting the cardiovascular, endocrine, and other systems.

Background: Arsenic emerges as most potent hazardous element ranked as number one in ATSDR (Agency for Toxic Substances and Disease Registry) list, can easily accumulate in fish, transported to humans via consumption and affect humans and aquatic organisms. Considering above, current experiment designed to evaluate cyto-genotoxicity and histological alterations induced by arsenic in Labeo rohita used as an animal model.
Methods: By applying complete randomized design sampling acclimatized individuals of Labeo rohita (10 batches of 10 each with triplicates) were exposed to nine definitive doses (12, 14, 16, 18, 20, 22, 24, 26 and 28 mgL) of arsenic in glass aquaria to determine 96-h lethal concentration (LC) of arsenic.
