We developed short tandem repeat markers for Palaemon septemtrionalis and tested their utility for analysing population genetics. Six markers were selected for their genotyping ability and suitability for population genetic analyses, and the genetic differences between two populations from different rivers were evaluated using these markers. The pairwise fixation index value between the two populations was 0.01756 (P=0.036), weak but statistically significant, suggesting a low level of genetic differentiation between the two populations. Although the results were not fully conclusive, we are confident these markers can be utilised for investigating the genetic population structure of P. septemtrionalis.

Juvenile muscular atrophy of the distal upper extremity (Hirayama disease) is a benign and non-progressive motor neuron disease. Application of a cervical collar is believed to prevent progression of symptoms in the early stages, but there is no effective therapy for the advanced disease. We found that tendon transfer improved the activities of daily living (ADL) of a patient with advanced Hirayama disease. An operative reconstruction can be valuable, even in patients with Hirayama disease who have developed impaired ADL due to extensive intrinsic hand muscle atrophy.
