Four granular nentaticides were evaluated for control of the yam nematode, Scutellonema bradys (Steiner &LeHew) Andrassy, on Guinea yam, Dioscorea rotundata Poir, under field conditions prevelant in the tropics. A single application of nematicides (sidedressing) at the rate of 2 kg ai/ha as postplanting treatment at the onset of the rainy season depressed numbers of S. bradys attacking yams dur...

We examined the effects of raw Chinese yam (Dioscorea opposita), containing resistant starch (RS), on lipid metabolism and cecal fermentation in rats. Raw yam (RY) and boiled yam (BY) contained 33.9% and 6.9% RS, respectively. Male Sprague-Dawley rats were fed a cholesterol-free, control (C) diet supplemented with or without 15 and 30 g of RY or BY/100 g for 3 wk. Plasma total cholesterol conce...

We measured bone mineral density of the distal end of radius with dual energy X-ray absorptiometry, serum cross-linked N-telopeptides of type I collagen, serum bone-specific alkaline phosphatase, serum Ca, serum P, blood PCB level, blood PCQ level and blood PCDF level in Yusho. As a result, the osteoporosis group (< 70% of the young adult mean [YAM] bone mineral density [BMD]) was observed in 7...

Discovering correspondences between schema elements is a crucial task for data integration. Most schema matching tools are semiautomatic, e.g., an expert must tune certain parameters (thresholds, weights, etc.). They mainly use aggregation methods to combine similarity measures. The tuning of a matcher, especially for its aggregation function, has a strong impact on the matching quality of the ...

28 Yam mosaic virus (YMV; genus Potyvirus) is considered to cause the most economically important 29 viral disease of yams (Dioscorea spp.) in West Africa which is the dominant region for yam 30 production globally. 31 Yams are a vegetatively propagated crop and the use of virus-free planting material forms an essential 32 component of disease control. Current serological and PCR-based diagnost...

The compressional characteristics and tableting properties of starches from four yam species namely Dioscorea dumetorum Pax (Bitter); Dioscorea oppositifolia L (Chinese); Dioscorea alata L.DIAL2 (Water) and Dioscorea rotundata Poir (White) were investigated in comparison with corn starch. The physicochemical properties of the starches were evaluated using established methods while the compressi...

To evaluate the genetic diversity and understand the evolution of Yam mosaic virus (YMV), a highly destructive pathogen of yam (Dioscorea sp.), sequencing was carried out of the C-terminal part of the replicase (NIb), the coat protein (CP) and the 3'-untranslated region (3'-UTR) of 27 YMV isolates collected from the three main cultivated species (Dioscorea alata, the complex Dioscorea cayenensi...

Serum haematology and biochemical profile of weaner rabbits fed graded levels of yam peels replacing maize were evaluated. The experiment which lasted fifty-six days using 15 weaner rabbits was laid in a randomized complete block design using five dietary treatments with three replications each. The dietary treatments evaluated were 5%, 10%, 15%, 20% and 0% inclusion level of yam peels replacin...

Chinese yam is an important edible starch plant and widely cultivated in China. Its rhizome and bulbil are starch storage tissues below and above ground, respectively. In this paper, starches were isolated from the rhizome and bulbil of Chinese yam, and their structural and functional properties were compared. Both starches had an oval shape with an eccentric hilum and a CA-type crystalline str...
