The green rice leafhopper Nephotettix cincticeps (Uhler) is a commonly distributed pest of rice in East Asia. Early histological studies describe the presence of two bacteriome-associated symbionts and a rickettsial microorganism in N. cincticeps, but their microbiological affiliations have been elusive. We identified these bacterial symbionts using modern(More)
We examined the expression of the midkine (MK) and alpha-fetoprotein (AFP) genes in 15 paired human specimens obtained from hepatocellular carcinoma (HCC) and the corresponding noncancerous regions of the same patients. A total of 14 HCC but none of the noncancerous specimens were positive for the MK mRNA. In contrast, three HCC specimens and one(More)
RNA interference (RNAi) is a useful tool for gene functional studies in non-model insects and pest insects. Establishment of experimental conditions for RNAi, which differ from insect to insect, is important for evaluating the effect of dsRNA injection of relevant genes. When injecting dsRNA into the green rice leafhopper Nephotettix cincticeps (Uhler),(More)
