Yam (Dioscorea spp.) is a staple food crop and source of income for millions people in West Africa. Traditionally, Africa, yams are grown without any external inputs, leading to low tuber yields. The rapid decrease yield observed after the first yam cropping season has been ascribed nutrient depletion and/or accumulation yam-specific pests diseases. This led farmers grow on new surfaces under f...

Food poisoning is known to occur sporadically from time to time due to poor hygienic preparations. Its occurrence rarely assumes epidemic proportion. The objective was to report the occurrence of food poisoning due to yam flour among three families which occurred almost in quick succession between March and July 2007 among three families in Kano. They presented with diarrhea, vomiting, abdomina...

The effects of incorporating cyanoglucoside extracts from yam or dasheen into the diet of streptozotocin-induced diabetic Wistar rats were studied for four weeks. Intestinal lipase activity, and plasma glucose and lipid levels were determined. Also, liver total lipids, activities of ATP citrate lyase, pyruvate kinase and 6-phosphogluconate dehydrogenase were assessed. Dasheen extract significan...

When Guinea yam, Dioscorea rotundata Poir, was inoculated with Pratylenchus coffeae and Scutellonema bradys together, there was a 53% suppression of top growth, but when plants were inoculated separately there was a 29% suppression with P. coffeae and a 21% suppression with S. bradys. The reproduction of S. bradys was greatly inhibited when both nematode species were together on the same plant ...

The YAM++ system is a self configuration, flexible and extensible ontology matching system. YAM++ takes advantages of many techniques coming from different fields such as machine learning, information retrieval, graph matching, etc. in order to enhance the matching quality. In this paper, we briefly present the YAM++ approach and its results on OAEI 2012 campaign. 1 Presentation of the system Y...

Yam anthracnose disease (YAD), caused by the fungus Colletotrichum gloeosporioides Penz, is most damaging fungal of Dioscorea alata yam worldwide. Local varieties, which sustain Côte d'Ivoire’s farmers and other end-users livelihoods, are highly susceptible to this pathogen. Thus, there a need for developing new cultivars production in d'Ivoire. To achieve such objective, id...

The immunostimulating activities of mucilage fraction from yam were investigated. The proliferation of BSA-primed lymph node cells was enhanced between 4.1- to 10.9-fold compare to control, when cultured with 1 to 25 microg/mL of yam-mucilage fraction. It showed strong immunopotentiating activity than ginseng extract and as remarkable as Bifidobacterium adolescentis M101-4 known as a positive i...

INTRODUCTION Diabetic patients have a higher risk to osteoporotic fractures. Foods, such as yam, to oppose hyperglycemia, has been used to treatment of diabetes. OBJECTIVE The goal was assess the role of Brazilian yam (Dioscorea bulbifera) on glycemia and bone parameters of female diabetic rats. METHODS Female Wistar rats with 3 months age were allocated in three groups. Control group (C, n...

Smallholder farmers in southern Nigeria have relied on the cultivation of cassava, yam, maize and plantain for their livelihood generations. However, with rising climate variability soil degradation, many are adopting crop diversification as a viable alternative to improve productivity farmland by growing multiple crops. Therefore, this study was conducted examine factors that influence diversi...
