Although potato leafhopper, Empoasca fabae (Harris) (Hemiptera: Cicadellidae), is highly polyphagous, classic host studies do not recognize grapevines (Vitis spp.), as suitable hosts. Recently, injury has been reported and reproduction documented within grape vineyards, suggesting a host expansion for the leafhopper. To document this apparent expansion in host use, we determined whether grape p...

introduction: in order to study the effects of turpentine oil on the concentration of lipids and lipoproteins of rabbit ( as an animal model for human studies )35 healthy female rabbits were chosen and then randomly allocated into 13 groups. different percents of turpentine oil and other oil compounds like vegetable oil, cholesterol and animal oil were given to each group ( 5 rabbits ) separate...

In Japan, few grape cultivars related to Vitis vinifera existed 200 years ago, on account of Japan's high rainfall. Many V. labruscana and vinifera cultivars were introduced to Japan in the 19th century. Labruscana was grown instead of vinifera, mainly because of severe disease problems and a high incidence of berry cracking. Grape breeding for table use started in the 20th century, with the go...

Background: Peptic ulcer disease is a most common disease, whose incidence is increasing presently on account of demanding stressful life. Objectives: To evaluate and compare the antiulcer activity of the extracts of seed and skin of Vitis Vinifera (Grape) using two different doses (100 & 200 mg/kg). Methods: The extracts of seed and skin of Vitis Vinifera were investigated for their anti-ulcer...

We gathered genomic data from grapes (Vitis vinifera ssp. vinifera), a clonally propagated perennial crop, to address three ongoing mysteries about plant domestication. The first is the duration of domestication; archaeological evidence suggests that domestication occurs over millennia, but genetic evidence indicates that it can occur rapidly. We estimated that our wild and cultivated grape sam...

A chitinase was purified from Vitis vinifera Manzoni Bianco grape juice and characterized. On the basis of proteomic analysis of tryptic peptides, a significant match identified the enzyme as a type IV grape chitinase previously found in juices of other V. vinifera varieties. The optimal pH and temperature for activity toward colloidal chitin were found to be 6 and 30 °C, respectively. The enzy...

Introduction Raisin allergy is uncommon despite worldwide cultivation of grapes, which belong to the Vitis vinifera species of the Vitaceae family. There have only been rare reports of anaphylaxis in adults related to the consumption of grapes, wine or other grape products, mostly in Europe [1-4]. In children, even fewer case reports to grape exist [5]. We report an 8-year-old patient who devel...
