Hong Kong, as a special administrative region of the People’s Republic of China, is a metropolitan city in Asia with a population of approximately 7.4 million. This paper reflects the oral health care situation in Hong Kong. Water fluoridation was introduced in 1961 as the primary strategy for the prevention of dental caries. The fluoride level is currently 0.5 parts per million. Dental care is mainly provided by private dentists. The government’s dentists primarily serve civil servants and their dependents, with limited emergency dental service for pain relief offered to the general public. Nevertheless, the government runs the school dental care service, which provides dental treatments to primary school children through dental therapists. They also set up an oral health education unit to promote oral health in the community. Hong Kong had 2280 registered dentists in 2017, and the dentist-to-population ratio was about 1:3200. The Faculty of Dentistry at the University of Hong Kong is the only institution to provide basic and advanced dentistry training programs in Hong Kong. Dental hygienists, dental surgery assistants, dental therapists, and dental technicians receive training as paradental staff through the university or the government.

Conventional fluorescent probes with weak fluorescence signals and aggregation-caused quenching effect limits in biomarkers detection, thus requiring many labeled target molecules to combine their output to achieve higher signal-to noise. Here, we harness a "immune-sandwich" based affinity sensor with development of ultrabright aggregation-induced emission luminogens (AIEgens) microspheres as signal reporter. The fabricated sensor can simultaneously permit triple detection formats by naked eye, spectrum, and computer vision counting (termed "NeSCV sensor").

Lead (Pb), a highly toxic heavy metal, poses a significant global health risk, particularly to children. Widely used in paint manufacturing for its remarkable corrosion-resistance properties Pb exposure has been linked to severe health issues, including reduced neurotransmitter levels, organ damage, potentially leading to death in extreme cases. Children Are particularly vulnerable, with Pb toxicity primarily affecting the brain, reproductive, kidneys, and cardiovascular systems.

This paper aims to highlight the significant role of culture in human responses to global environmental challenges. Specifically, it discusses three thematic clusters of research, which demonstrate that: (i) culture can influence pro-environmental behavior through shaping values and moderating the relationship between psychological determinants and such behavior; (ii) perceptions of nature and its relationships with humans vary across cultures; and (iii) consumption behaviors are often shaped by practices that constitute social life within communities. Evidence from these research clusters suggests that understanding cultural dynamics is essential for designing effective, context-sensitive interventions aimed at driving sustainability transitions.

Background: Gut microbiota plays an important role in multiple human physiological processes and an imbalance in it, including the species, abundance, and metabolites can lead to diseases. These enteric microorganisms modulate immune homeostasis by presenting a myriad of antigenic determinants and microbial metabolites. Medicinal and food homologous (MFH) plants, edible herbal materials for both medicine and food, are important parts of Traditional Chinese Medicine (TCM).
