House Musk Shrews (Suncus murinus) Do Not Copulate in the Light Period when First Paired in the Dark
The copulatory behavior pattern of house musk shrews paired for 24 h starting at either 09:00 (light) or 20:00 (dark) was investigated. Ejaculatory behaviors were observed in both light and dark periods, when mating was started at 09:00. However, the males ejaculated only in the dark period when they were paired at 20:00
A Case of Hypocalcaemia Due to Vitamin D Deficiency in ‘Hikikomori’ Syndrome
Objective: To describe hypocalcaemia due to vitamin D deficiency in ‘hikikomori’ syndrome.
Materials and methods: A 37-year-old man with ‘hikikomori’ syndrome for a year was admitted with hypocalcaemia (serum ionic calcium 1.17 mmol/l). Serum 1,25(OH)2-vitamin D3 determined by liquid chromatography–tandem mass spectrometry was depressed at 12.1 pg/ml (29.0 pmol/l) and plasma intact PTH elevated at 324 ng/l. Administration of 1 μg/day 1α(OH)-vitamin D3 and 1 g/day calcium lactate for 1 week normalized calcium and PTH, and raised 1,25(OH)2-vitamin D3 to low normal levels.
Conclusion: This is the first report of hypocalcaemia due to vitamin D deficiency in a patient with ‘hikikomori’ syndrome

Copulatory behavior of male house musk shrews (Suncus murinus)
The copulatory behavior in male house musk shrews (Jic: SUN strain) aged 10-12 months was observed under the light (09:00-11:00) and dark (20:00-22:00) periods. The females of same strain were used as stimulus in copulatory behavior tests.Two-hour test sessions were recorded. All 14 males showed one ejaculation after a few intromissions within 2 hours. These values are similar to that of male guinea pigs. Comparing behavioral frequencies and latencies for males observed in thelight and dark periods, there were no significant differences between two groups. The present study is the first to clearly establish the pattern of copulatory behavior in male house musk shrews
Study of Negative-Ion TPC Using {\mu}-PIC for Directional Dark Matter Search
Negative-ion time projection chambers(TPCs) have been studied for low-rate
and high-resolution applications such as dark matter search experiments.
Recently, a full volume fiducialization in a self-triggering TPC was realized.
This innovative technology demonstrated a significant reduction in the
background with MWPC-TPCs. We studied negative-ion TPC using the {\mu}-PIC+GEM
system and obtained sufficient gas gain with CSgas and SF gas at
low pressures. We expect an improvement in detector sensitivity and angular
resolution with better electronics
