Generational changes in lung function in adults from several world regions: results from the Burden of Obstructive Lung Disease study

This study estimated birth cohort effects on lung function using BOLD (Burden of Obstructive Lung Disease) data from 28 569 adults born between 1902 and 1976 across 41 sites in 34 countries. Forced vital capacity (FVC), forced expiratory volume in 1 s (FEV 1 ) and the FEV 1 /FVC...

Spatial Variation in Heavy-Metal Bioaccumulation and Associated Physiological Stress Biomarkers in Bufo regularis Across Three Different Locations in Southwestern Nigeria

Urbanisation is a major driver of environmental contamination, yet its physiological consequences for amphibians in rapidly developing regions remain poorly understood. This study investigated spatial variation in heavy-metal bioaccumulation and associated physiological stress bi...

Development and validation of Roots and Greens: a Whatsapp-based nutrition education program promoting indigenous produce among youth

The delivery of nutrition education through familiar social media platforms like WhatsApp provides the opportunity to facilitate positive dietary behaviors among young adults in low-resource settings. However, many WhatsApp nutrition education curricula were not developed using s...
