Shan Gao (Gao 2011) recently presented a critical reconsideration of a paper I wote (Uffink 1999) on the subject of protective measurement. Here, I take the occasion to reply to his objections.

Yam (Dioscorea opposita) is commonly consumed in East Asia, but allergic reaction to this plant food is rare. To date, there is no report of anaphylactic reaction after ingestion of cooked yam. We described 3 cases with anaphylaxis after eating boiled yam and 1 present with oral allergy syndrome as well. Basophil activation test in patients showed positive reactivity to boiled yam extract. In i...

Dioscorea cayenensis and Dioscorea rotundata are among the most important yam species for the humid and sub-humid tropics. We isolated nine polymorphic microsatellite markers using a microsatellite-enriched genomic library technique. The nine primer pairs were validated in 22 D. cayenensis accessions, and were tested for transferability in 26 D. rotundata accessions. The number of bands ranged ...

Yams (Dioscorea spp.) are food crops of growing significance in sub Saharan Africa. Unfortunately, nematodes are major pests to their production. A study was undertaken in major yam growing areas of Uganda to investigate the association of plant parasitic nematodes with damage symptoms. Nematodes were assessed from tubers, roots and surrounding soil for seven cultivars belonging to Dioscorea al...

UNLABELLED PREMISE OF THE STUDY Microsatellite loci were isolated and characterized from enriched genomic libraries of two taxa of the Chilean Epipetrum group of Dioscorea to assess their levels of genetic diversity and population differentiation. • METHODS AND RESULTS Eleven microsatellite loci were identified. Six out of nine microsatellites from D. biloba amplified in D. humilis, and th...

Widely spread in the tropics, yams were introduced into Brazil during the colonial period and are currently grown throughout the country. Despite its importance as a pharmacological and food source, there is a lack of studies describing how and where this tuber is grown in Brazil. The aim of this study was to provide an overview of the cultivation and distribution of Dioscorea alata in differen...

The title compound, C(11)H(13)N(3)O, is a derivative of the anti-tuberculosis drug isoniazid [systematic name: pyridine-4-carbohydrazide]. The crystal structure consists of repeating hydrogen-bonded chains parallel to the b axis. Adjacent mol-ecules in the chains are linked by bifurcated N-H⋯(O,N) hydrogen bonds, which form an R(1) (2)(5) ring motif.

Yam (Dioscorea species) is a monocotyledonous tuber forming tropical vine which belongs to the order Liliflorae, family Dioscoreaceae, and genus Dioscorea. Conventional propagation of yam (Dioscorea spp.) limited due low rates highly infected by pests. However, In vitro clonal best alternative mass multiplication over conventional propagation. Moreover, shoot ...

The biochemical changes occurring during growth and storage of two yam cultivars (Dioscorea rotundata cv. Oshei and Dioscorea dumetorum cv. Jakri) were studied. Tubers were harvested at monthly intervals from the fourth to the tenth month after 50% emergence of the planted yam sets. For storage studies, Oshei and Jakri tubers were harvested 9.5 and 9 months post-emergence, respectively. These w...
