Nutritional and therapeutic potentials of Carica papaya Linn. seed: A comprehensive review

The health benefits and nutritional value of pawpaw or papaya (Carica papaya Linn.) are well established. The entire papaya plant—including the leaves, fruit, bark, root, juice, seeds and latex - is used for dietary, medicinal and other purposes. However, papaya seeds are the under-exploited part since they are typically seen as waste after the edible fruits have been processed and consumed. Hence, the aim of this review is to document the nutraceutical and therapeutic potential of Carica papaya seeds with a view of enhancing its prospect in drug development. The following title search criteria were used “Carica papaya” OR “Papaya” OR “Pawpaw OR C. papaya” AND “seed” OR “seed oil”; while “fruits OR leaves OR stem OR root OR juice OR latex” were excluded. The articles used for this research were limited to the original research articles and those written in English Language only. The seeds which are often seen as waste products offer countless possibilities for developing new nutritional supplements and medicines due to the huge vital micronutrients and a variety of secondary metabolites that have been reported to be embedded in them. Papaya seeds contain beneficial phytochemicals such as carotenoids, flavonoids, alkaloids, phytosterols and tocopherols. These substances, have intriguing nutraceutical qualities and are important in the treatment and amelioration of several medical disorders. Benzyl glucosinolates, caricin, fatty acids, crude fibre, carpaine, glucotropaeolin, benzyl isothiocyanate, crude protein, benzyl thiourea, hentriacontane, ß-sitostrol and enzymes (myrosinase and papain) were discovered as nutritional components in papaya seeds. Papaya seeds may be used medicinally as antioxidant, antidiabetic, antiulcerogenic, liver cirrhosis treatment and menstrual cycle modulation.

Competing CO and HCOOH Pathways in CO2 Electroreduction

Human activities have significantly contributed to the increase in global carbon emissions, leading to adverse environmental effects such as global warming. Electrochemical reduction of carbon dioxide (CO2RR) presents a promising approach to mitigate carbon emissions. This process not only stores the low energy density renewable energies into high energy density chemical bonds, but also produces a variety of valuable products, including one‐carbon products like HCOOH and CO, as well as multi‐carbon products like CH3CH2OH and C2H4. Among them, HCOOH and CO can be produced with over 90% selectivity on various catalysts, indicating their potential for large‐scale applications. However, the precise reaction pathways toward CO and HCOOH remain unclear, and the competition between these pathways often leads to low product selectivity. This review provides an overview of current research on the selective reduction of CO2 to CO and/or HCOOH, encompassing theoretical simulations, catalyst design, and investigations into reaction mechanisms. Additionally, this review highlights the challenges and prospects for the further development and understanding of selective catalysts for CO and HCOOH production, aiming to provide valuable insights for future studies in this intriguing and significant research field.

Research Progress in the Detection of Aflatoxin B1 Based on Aptamers

Abstract: Aflatoxin B1 is highly toxic, mutagenic, teratogenic, and carcinogenic and is a class I carcinogen. Peanuts, cotton, and corn may be affected by AFB1 during cultivation, which can seriously jeopardize human health. Developing a simple, sensitive, and selective method for detecting AFB1 is imminent. Aptamers are obtained through in vitro screening of ligands by single-stranded oligonucleotides (DNA or RNA) through exponential enrichment (SELEX) technology. As emerging highly selective recognition molecules, they have the advantages of strong affinity, good stability, and strong specificity. Because it does not have the function of signal conversion, it cannot produce physicochemical signals that can be detected in the process of specific binding with target molecules, so it is necessary to convert the process of specific binding of aptamers to target molecules into a process of easily detectable physicochemical signal changes. According to different conversion methods, aptamer biosensors are divided into electrochemical aptamer sensors, fluorescent aptamer sensors, colorimetric aptamer sensors, surface Raman-enhanced aptamer sensors, and so on. Herein, the recent progress and application of aflatoxin B1 detection by nucleic acid aptamer biosensors based on the above signals are reviewed, and the future development prospects and challenges of this kind of biosensor are summarized.
