Emerging evidence indicates that postmenopausal women with periodontitis have aggravated inflammation and prolonged course, with the detailed mechanisms largely unknown. This study aimed to determine the pathogenic role of aberrant extracellular vesicles due to imbalanced-polarized macrophages and explore the therapeutic approach for periodontitis in postmenopausal individuals. Periodontitis in ovariectomized (OVX) mouse models were established to simulate the aggravated periodontitis in postmenopausal women.

Producing clean, fresh drinking water from atmospheric water vapor can play an important role in alleviating water scarcity in drought-prone regions of the world. This perspective explores the current trends and future outlook for atmospheric water harvesting technologies.
To what extent is scientific research related to societal needs? To answer this crucial question systematically we need to contrast indicators of research priorities with indicators of societal needs. We focus on rice research and technology between 1983 and 2012. We combine quantitative methods that allow investigation of the relation between ‘revealed’ research priorities and ‘revealed’ societal demands, measured respectively by research output (publications) and national accounts of rice use and farmers’ and consumers’ rice-related needs.
