Natural silk protein nanoparticles are a promising biomaterial for drug delivery due to their pleiotropic properties, including biocompatibility, high bioavailability, and biodegradability. Chinese oak tasar Antheraea pernyi silk fibroin (ApF) nanoparticles are easily obtained using cations as reagents under mild conditions. The mild conditions are potentially advantageous for the encapsulation...

-1. Wing epidermis from diapausing and non-diapausing silkmoths (Antheraea pernyi) was assayed for NADH [nicotinamide adenine dinucleotide (reduced form)] oxidase, NADHand succinate-cyctochrome c reductases, and cytochrome c oxidase. 2. Diapausing pupae showed a marked decline in activities after pupation and the same subsequent profile of very low activities reported for diapausing Cecropia si...

Larvae of the Chinese oak silkmoth (Antheraea pernyi) are often affected by AVD (A. pernyi vomiting disease), whose causative agent has long been suspected to be a virus. In an unrelated project we discovered a novel positive sense single-stranded RNA virus that could reproduce AVD symptoms upon injection into healthy A. pernyi larvae. The genome of this virus is 10,163 nucleotides long, has a ...

Ultrastructural study of the prothoracic glands of silkworms (Antheraea pernyi and Bombyx mori) at the last two larval stages has shown that the essential modifications which take place during each intermolt affect the chondriome of secretory cells. A description is given of the differentiation of macromitochondria from typical mitochondria by a general swelling, a clearing of the matrix, and t...

The complete mitochondrial genome (mitogenome) of Eriogyna pyretorum (Lepidoptera: Saturniidae) was determined as being composed of 15,327 base pairs (bp), including 13 protein-coding genes (PCGs), 2 rRNA genes, 22 tRNA genes, and a control region. The arrangement of the PCGs is the same as that found in the other sequenced lepidopteran. The AT skewness for the E. pyretorum mitogenome is slight...

The phylogenetic relationships between Bombyx mori and Bombyx mandarina species of Bombycidae, and Antheraea yamamai and Antheraea pernyi species of Saturniidae were investigated based on mtDNA RFLP and cytochrome oxidase I gene. The sizes of the mtDNA of all the species were estimated at approximately 16 kbp +/- 500 bp by total length of all the restricted fragments and no variation in size wa...
