High beta-carotene maize, biofortified with beta-carotene through plant breeding, is being developed as a cost-effective, sustainable agronomic approach to alleviating the problem of vitamin A deficiency in Africa. We used high beta-carotene maize (10.49+/-0.16 microg beta-carotene/g) to prepare
In the current study, African catfish, Clarias gariepinus, was exposed to a sublethal concentration of carbofuran (CF) to investigate its negative effects on biochemical and oxidative stress biomarkers. Also, the putative role of lycopene (LYC) administration in alleviating these negative effects
Maize (Zea mays L.) is a staple crop providing food security to millions of people in sub Saharan Africa. Fusarium verticillioides, an important fungal pathogen, infects maize causing 'Fusarium Ear Rot' disease, which decreases maize kernel yield and the quality of the crop
A synthesis of available agronomic datasets and peer-reviewed scientific literature was conducted to: (1) assess the status of micronutrients in sub-Saharan Africa (SSA) arable soils, (2) improve the understanding of the relations between soil quality/management and crop nutritional quality and (3)
Physiological and molecular responses to phosphorus (P) supply and mycorrhizal infection by Glomus intraradices were compared in European (River) and African (H511) maize (Zea mays) cultivars to examine the extent to which these responses differed between plants developed for use in high- and
Vegetable milks were developed from fermented and unfermented African yam bean (AYB) flours and their maize blends. AYB was cleaned, dehulled, milled and fermented for 24 hours by the natural microflora present in the legume flour. Maize was fermented for 48 hours. A ratio of 70:30 (protein basis)
Maize streak virus (MSV), the causal agent of maize streak disease (MSD), is the most important viral pathogen of Africa's staple food crop, maize. Previous phylogeographic analyses have revealed that the most widely-distributed and common MSV variant, MSV-A1, has been repeatedly traversing Africa
Peanut oils were obtained from the United States (NAPNO), Africa (APNO), and South America (SAPNO) and their effects on atherosclerosis in rabbits fed 2% cholesterol were determined. The major differences among the oils were in the content of oleic (NAPNO, 48.9%; APNO, 58.6%; SAPNO, 36.4%) and
The effects of organic nitrogen, nitrate, phosphorus, potassium and water content of leaves of intact maize plants, grown in a gravel culture system, on the fitness of the African armyworm, Spodoptera exempta (Walker)(Lepidoptera: Noctuidae) were studied. Organic nitrogen concentrations ranged from
The current study examined how African American fathers' dietary practices were associated with their children's dietary consumption. The sample consisted of one hundred and two African American fathers, who had children between the ages of three and thirteen. The fathers provided self-reports of
To determine whether proximity to flowering maize enhances the development of larval anopheline mosquitoes breeding in turbid water and when crowded, we evaluated the development of larval Anopheles arabiensis under various conditions of turbidity, larval density, and proximity to pollen-shedding
BACKGROUND
The consumption of added sugars (eg, white sugar, brown sugar, and high-fructose corn syrup) displaces nutrient-dense foods in the diet. The intake of added sugars in the United States is excessive. Little is known about the predictors of added sugar intake.
OBJECTIVE
To examine the
BACKGROUND
Larviciding is a key strategy used in many vector control programmes around the world. Costs could be reduced if larvicides could be manufactured locally. The potential of natural products as larvicides against the main African malaria vector, Anopheles gambiae s.s was
Cotesia flavipes (Cameron) (Hymenoptera: Braconidae) is used as a classical biological control agent against Chilo partellus (Swinhoe) (Lepidoptera: Crambidae), a serious exotic pest of cereal crops in eastern and southern Africa. This parasitoid has been introduced into several African countries
The genus Striga comprises about 30 obligate root-parasitic plants, commonly known as witchweeds. In particular, S. hermonthica, S. asiatica and S. gesnerioides cause immense losses to major stable crops in sub-Saharan Africa. Most Striga species parasitize grass species (Poaceae), but Striga
