A species of cyclopoid copepod Anthessius cucullatus Lee and Kim, 2021 (Anthessiidae) is newly recorded based on both sexes collected from three species of the sea slug genus Aplysia Linnaeus, 1767, i.e., Ap. dactylomela Rang, 1828, Ap. juliana Quoy and Gaimard, 1832, and Ap. kurodai Baba, 1937, from coastal waters of Kagoshima Prefecture, southern Japan. The copepod is characterized by having the following characters in the female: 1) the genital double somite covered with a hood-like dorsal lobe; 2) the antenna with four unequal claws and three setae at the distal tip; 3) the maxilla has a spinulose basal lobe; 4) leg 5 with irregular marginal rows of spinules. Furthermore, the male has 5) the third endopodal segment of leg 4 bearing a curved third inner spine. The findings of An. cucullatus in this study represent the second record of the copepod from all around the world as well as the first record from Japanese waters with the detailed description of the morphological characters based on the specimens. Aplysia dactylomela and Ap. juliana are new host records of the copepod.

We herein report a case of peripheral neuropathy following exposure to large amounts of glyphosate-based herbicide. A 70-year-old man suffered from pain and purpura in the left sole following exposure to glyphosate-based herbicide. Pain and purpura spread to the opposite side and increased in severity. Mild weakness of the lower limbs was also observed. A sural nerve biopsy revealed the infiltration of lymphocytes around small vessels in the epineurium with numerous eosinophils, deposition of hemosiderins and focal axonal degeneration, compatible with findings of vasculitic neuropathy. Glyphosate-based herbicides should be recognized as a causative agent of vasculitic neuropathy.

Maintaining a good ventricular systolic function is important in the long-term therapy of dogs with supraventricular tachyarrhythmia (SVTA). The objective of this study was to evaluate the inhibitory effect of telmisartan on myocardial injury and the resulting ventricular systolic dysfunction in a canine model of SVTA. A total of 14 dogs were randomly assigned to a Telmisartan (oral telmisartan, 1.0 mg/kg daily, n=7) or a Control (no drug administration, n=7) group; the duration of rapid atrial pacing (RAP) was 3 weeks for both groups. The cardiac troponin I (cTnI) concentration in the Control group was significantly increased after 3 weeks compared to that before RAP initiation (baseline), but no significant difference was observed in the Telmisartan group. Moreover, the cTnI concentration at 3 weeks was significantly lower in the Telmisartan group than in the Control group. The left ventricular fractional shortening was significantly decreased at 3 weeks compared to that at baseline in both groups. However, fractional shortening at 3 weeks was significantly higher in the Telmisartan group than in the Control group. The cardiac output values in the Control group were significantly decreased at 3 weeks compared with those at baseline, but no significant difference was observed in the Telmisartan group. This study demonstrates that telmisartan inhibits the reduction in ventricular systolic function and prevents myocardial injury in a canine model of SVTA. Therefore, telmisartan is suggested as a novel treatment for canine SVTA.
