Selenium Methylation: Insights into Chemical Reactions and Enzymatic Pathways Open
Selenium, an essential metalloid, plays a dual role in biological systems: while crucial for maintaining normal biological processes, excessive levels can be toxic. Organisms mitigate selenium toxicity through a biochemical process known a…
Selenium Methylation: Insights into Chemical Reactions and Enzymatic Pathways Open
Selenium, an essential metalloid, plays a dual role in biological systems: while crucial for various physiological functions, its excess can lead to toxicity. Organisms mitigate selenium toxicity through a biochemical process known as meth…
Selenium health impacts and Sub-Saharan regional nutritional challenges: Review Open
Selenium is an important micronutrient that plays key functions in antioxidant defense, immune function, and thyroid health. However, its benefits and risks are closely linked to selenium methylation, a process that significantly influence…
Knowledge, Attitude, and Practices of Food Hygiene among Mothers from Rural Communities in Malawi Open
This study assessed knowledge, attitudes, and practices related to food hygiene among mothers from Malawi’s rural communities against the WHO Five Keys to Safer Food (WHO-FKSF) and good pre-and post-harvest practices (GPPHPs) as reference …
Methylation of arsenic in rice: Mechanisms, factors, and mitigation strategies Open
Arsenic contamination in rice poses a significant health risk to rice consumers across the globe. This review examines the impact of water source and type on the speciation and methylation of arsenic in rice. The review highlights that gro…
Safety of African grown rice: Comparative review of As, Cd, and Pb contamination in African rice and paddy fields Open
This review aimed to investigate the reported concentrations of arsenic (As), cadmium (Cd), and lead (Pb) in rice cultivated in Africa and African rice paddies compared to other regions. It also aimed to explore the factors influencing the…
Reduction of aflatoxins during brewing of a Malawian maize‐based non‐alcoholic beverage, <i>thobwa</i> Open
This study reports onthe effect of various production steps on levels of aflatoxins during preparation of thobwa , a traditional maize‐based fermented non‐alcoholic beverage, brewed across Malawi. The effect of boiling, fermentation and th…
Alleviating cobalt and lead toxicity in rice using zero valent iron (Fe°) amendments Open
Simultaneous impact of zero valent iron (Fe°) and rice cultivar on uptake, translocation, and bioaccumulation of cobalt (Co) and lead (Pb) in rice (Oryza sativa L.) was investigated to alleviate Co and Pb toxicity in rice. Kilombero and Fa…
Evaluation of Metal(loids) Concentrations in Soils of Selected Rice Paddy Fields in Malawi Open
The aim of this study was to obtain baseline data for heavy metal(loids) concentrations of rice paddy fields to evaluate the impacts of soil metal(loids) concentrations on quality of rice, and to identify sources of metal(loids) pollution …
Impact of soil-type, soil-pH, and soil-metal (loids) on grain-As and Cd accumulation in Malawian rice grown in three regions of Malawi Open
Impact of soil type, soil-metal(loids) and soil-pH of rice paddies on grain-arsenic (As) and cadmium (Cd) accumulation in Malawian rice was investigated to explore the extent to which Malawi's geographical location, soil types, soil-metal(…
