Pesticide usage in agriculture has occurred for centuries and led to significant positive outcomes in food production and noticeable reduction in crop losses. However, pesticide usage on food crops often results in the presence of toxic pesticide residues on food produce, which is the main route of exposure to pesticides in humans. The toxicity of the pesticide residues can potentially cause debilitating effects to major human organs and body systems. Pesticide residue analysis addresses the issue of pesticide residues in foods by screening and quantifying the levels of pesticides in food commodities.
Oral malodour called halitosis, and commonly referred to as ‘bad breath’, is a socially offensive and discriminating occurrence that requires effective management for health improvement and avoidance of debasing stratification of sufferer. Halitosis has been reported to be prevalent in up to 50% of the general population in the USA, and about 6-23% in China. Between 80% and 85% of halitosis cases are caused by intraoral conditions. Literature on halitosis in Jamaica is either scarce or non-existent. Prior to the COVID-19 pandemic, a common malodour that seemed to be spreading among persons through oral interaction by face-to-face contact with a sufferer was observed among the general populace in Mandeville, Manchester, Jamaica.
Invasive alien species (IAS) are implicated in the extinction or decline of numerous native aquatic species worldwide. Their negative impacts occur through mechanisms including habitat alteration, competition, predation, hybridisation, and the spread of disease (Strayer et al. 2006). Small island ecosystems are most susceptible to the impacts of IAS. Once established, freshwater IAS are difficult to eradicate without negatively impacting native species.
Science and technology and its application to regional development
The malaria epidemic was responsible for about 241 million infectious cases and 627,000 deaths worldwide in 2020.[1] This infectious disease, transmitted by the female Anopheles mosquito, is caused by parasites of the genus Plasmodium namely P. falciparum, P. vivax, P. malariae, P. knowlesi, P. ovale curtisi and P. ovale wallikeri.[2,3] Also, malaria is found predominantly in the highlands of Africa which accounts for more than 90% of infections worldwide. While there has been some success in the treatment of malaria, its eradication has been negatively impacted by insecticide and drug resistance. With emergence of thiosemicarbazone as antimalarial agents, the combination of pyridine and amide or thioamide moieties into one scaffold makes for an interesting target.[4]
