A novel coronavirus disease (COVID-19) or severe acute respiratory syndrome-related coronavirus 2 (SARS-CoV-2), transmitted from person to person, has quickly emerged as the pandemic responsible for the current global health crisis. This infection has been declared a global pandemic, resulting in a concerning number of deaths as well as complications post-infection, primarily among vulnerable groups particularly older people and those with multiple comorbidities. In this article, we review the most recent research on the role of date palm (
Phoenix dactylifera
L.) fruits (DPFs) to prevent or treat COVID-19 infection. The mechanisms underlying this preventive or therapeutic effect are also discussed in terms of bioactivity potentials in date palm, e.g., antimicrobial, antioxidant, anticancer, anti-diabetic, anti-inflammatory, neuroprotective, and hemolytic potential, as well as prospect against COVID-19 disease and the potential product development. Therefore, it can be concluded that regular consumption of DPFs may be associated with a lower risk of some chronic diseases. Indeed, DPFs have been widely used in folk medicine since ancient times to treat a variety of health conditions, demonstrating the importance of DPFs as a nutraceutical and source of functional nourishment. This comprehensive review aims to summarize the majority of the research on DPFs in terms of nutrient content and biologically active components such as phenolic compounds, with an emphasis on their roles in improving overall health as well as the potential product development to ensure consumers’ satisfaction in a current pandemic situation. In conclusion, DPFs can be given to COVID-19 patients as a safe and effective add-on medication or supplement in addition to routine treatments.
A smell in industrial product design is defined as an awareness of the dimensions in design creation. Theoretical development for the role of smells in design has led to a significant increase in industrial design. However, despite numerous studies on smells within industrial design, a holistic overview through systematic reporting remains unavailable. In this paper, the authors conducted a systematic review of studies on smells in academic articles on industrial design. The review method was adopted from the Reporting Standards for Systematic Evidence Syntheses (ROSES). The academic databases involved are Scopus, Science Direct, Web of Science and Google Scholar. This study discovered that studies on smells in industrial design have researched the following aspects: 1) smells as design attributes; 2) users' perceptions based on smells; and 3) appraisals of smells embedded in products. Practitioners, educators and researchers can use this systematic review to examine the needs of smell-related sensorial concerns in the current product design applications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
