BACKGROUND Anxiety levels in rats are correlated with interleukin-2 (IL-2) levels in the brain. The aim of the present study was to investigate the effects of dioscorea (wild yam), a Chinese medicine, on emotional behavior and IL-2 levels in the brain of ovariectomized (OVX) rats. METHODS One month after ovariectomy, female Wistar rats were screened in the elevated plus-maze (EPM) test to mea...
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...
Dioscorea nipponica Makino, a perennial herb growing in mountainous areas of the Chinese Changbai mountains and Korean peninsula, has long been used as a folk medicine for bronchitis, asthma, and rheumatoid arthritis. Due to these therapeutic properties, wild Dioscorea nipponica Makino resources become less and less, some wild species have been tamed to be cultivated ones. In this paper, we com...
The present study was designed to determine the physicochemical properties of yam (Dioscorea) solution fermented by L. bulgaricus, the protective effect of fermented Dioscorea opposita Thunb. on stomach lesions, and the possibility of its application to fermented dairy products. When the concentration of yam increased, the pH increased in raw powder samples but not in extracted powder samples. ...
Dioscorea species, known as “Yams,” belong to family Dioscoreaceae. This genus consists ofmore than 600 species distributed from Africa, Asia, the Caribbean’s South America, and theSouth Pacific islands. Their organoleptic properties make them the most widely used carbohydratefood and dietary supplements. The underground and/or aerial tubers represent valuable sources...
PREMISE OF THE STUDY Dioscorea alata L. is one of the most widely distributed species of the genus in the humid and semihumid tropics and is associated with traditional agriculture. Only a few microsatellite markers have been developed so far for this and other Dioscorea species. METHODS AND RESULTS We isolated 14 codominant polymorphic microsatellite markers using a microsatellite-enriched g...
Extraction of RNA from Dioscorea is difficult because of rich mucilage and secondary metabolite content. High-quality RNA is required for RT-PCR and transcriptome analysis. Different protocols and common extraction kits were used for RNA extraction in Dioscorea, but the results were not satisfactory. A CTAB based protocol with lithium chloride precipitation yielded good quality RNA. The RNA iso...
The data presented in this article are related to research article titled "Effects of processing methods on nutrient and antinutrient composition of yellow yam (Dioscorea cayenensis) products" (Adepoju et al., 2016) [1]. This article documented information on nutrient and antinutrient composition as well as nutrient retention of Dioscorea cayenensis products. Fresh Dioscorea cayenensis tubers o...
In addition to the importance of many Dioscorea species (yams) as starchy staple food, some representatives are known and still used as a source for the steroidal sapogenin diosgenin, which, besides phytosterols derived from tall-oil, is an important precursor for partial synthesis of steroids for pharmaceutical research and applications. While in edible yams the diosgenin content should be as ...
ETHNOPHARMACOLOGICAL RELEVANCE Dioscorea nipponica (Dioscoreaceae) have been used as traditional medicines for diabetes, inflammatory and neurodegenerative diseases in Korea. The aim of the study was to isolate the bioactive components from the rhizomes of Dioscorea nipponica and to evaluate their anti-neuroinfalmmatory and neuroprotective activities. MATERIAL AND METHODS The phytochemical in...
