ABSTRACT
Abstract The mitochondrial genome (mitogenome) characteristics of the monotypic Lasiocampoidea are largely unknown, because only limited number of mitogenomes is available from this superfamily. In this study, we sequenced the complete mitogenome of the lappet moth, Kunugia undans (Lepidoptera: Lasiocampidae) and compared it to those of Lasiocampoidea and macroheteroceran superfamilies (59 species in six superfamilies). The 15,570-bp K. undans genome had one additional trnR that was located between trnA and trnN loci and this feature was unique in Macroheterocera, including Lasiocampoidea. Considering that the two trnR copies are located in tandem with proper secondary structures and identical anticodons, a gene duplication event might be responsible for the presence of the two tRNAs. Nearly all macroheteroceran species, excluding Lasiocampoidea, have a spacer sequence (1-34 bp) at the trnS2 and ND1 junction, but most lasiocampid species, including K. undans, have an overlap at the trnS2 and ND1 junction, which represents a different genomic feature in Lasiocampoidea. Nevertheless, a TTAGTAT motif, which is typically detected in Macroheterocera at the trnS2 and ND1 junction, was also detected in all Lasiocampoidea. In summary, the general mitogenome characteristics of Lasiocampoidea did not differ greatly from the remaining macroheteroceran superfamilies, but it did exhibit some unique features.
ABSTRACT
Both vein and arterial involvements with various manifestations in Beh et's disease is defined as vasculo-Beh et's disease. Venous lesions such as thrombosis or varices are more common than arterial lesions. Aneurysms or arterial steno-occlusion involving large intracranial arteries are very rare. We report two cases of vasculo-Beh et's disease involving intracranial arteries. The one case presented with carotid-cavernous sinus fistula due to internal carotid aneurysm, and the other case was accompanied by cerebral infarct due to intracranial arterial stenosis.
