The house musk shrew Suncus murinus has successfully been domesticated for laboratory use both in the United States and Japan. Animals of this species have been found to be useful for behavioural studies in comparative psychology and the related fields. This article dealt with basic characteristics, ecological modes, maintenance of laboratory shrews, basic patterns of behaviour, and assessment of the species as a laboratory animal for behavioural studies. Basic characteristics covered phylogenetic status, morphology, growth, sensory functions, and motor functions. Although its ecology has not yet b en systematically investigated due to the difficulties for observing animals in the wild, some findings on the seasonal and locational variations of the population density in its natural habitat were obtained on the basis of the result of trapping. Keeping and breeding the already domesticated animals in an artificial environment as well as domesticating wild-originating animals were described. Characteristics of the caravaning behaviour were mentioned in relation to its sensitive period, its formation patterns, and development of the sensory and motor functions. Those findings were discussed in connection with its adaptive significance. Also, characteristics of the reproductive behaviour were represented. Behavioural interaction between sexes is expected to determine mating outcome, since the female is an induced ovulator, having no ovarian, vaginal, or behavioural oestrus cycle. Sequential pattern of the behaviour was described with reference to the male's pacifying behaviours and the postejaculatory attack towards the partner female. Together with those two observations, the activity rhythm, aggressive and learning behaviours were mentioned. Lastly, this species was assessed as a laboratory animal for behavioural studies.

Bilateral phrenic nerve paralysis (BPP) is a relatively rare disease manifested by slight dyspnea at rest and on exertion in the sitting and standing positions and by dyspnea in the supine position. A 67-year-old man, who was a painter presented with severe pain in both shoulder regions that had evolved into orthopnea and forced him to sleep in a sitting position at night. Dyspnea and paradoxical respiratory movement in the supine position raised suspicions of BPP. The most striking feature in this case was that the rapid onset of pain in both shoulder regions was followed by BPP. The BPP was considered to be secondary to neuralgic amyotrophy (NA).

[Purpose] The characteristics of heart failure in hospitalized patients with poor self-care behaviors are unknown. We investigated factors associated with self-care behaviors by using the European Heart Failure Self-Care Behaviour Scale (EHFScBS) in heart failure patients based on three comprehensive concepts. [Participants and Methods] This was a cross-sectional single-center study of heart failure patients hospitalized at a tertiary-care hospital. We investigated age, gender, family living together/apart, employment, and the Specific Activity Scale (SAS). A physical therapist provided the EHFScBS one time to determine the patients’ pre-hospital self-care behavior status. The 12 items of the EHFScBS were classified into the following three categories: Maintenance, Monitoring, and Management. [Results] The median age of the 39 consecutive patients was 81 years. A multiple regression analysis revealed that the factors exhibiting significant associations were the SAS score (β=0.504) for Management and age (β=−0.403) for the total EHFScBS score (adjusted by the number of hospitalizations for heart failure). Maintenance and Monitoring were not significantly associated with the survey items. [Conclusion] These data indicate that self-care education for hospitalized patients with heart failure leads to individualized approaches based on characteristics such as age and physical activity capacity.

Insect odorant-binding proteins function in the sensing of odors, tastes, and pheromones. Genes encoding two odorant-binding proteins, Obp57d and Obp57e, were identified to be involved in the behavioral adaptation of Drosophila sechellia to its host plant. The two genes are expressed in cells associated with taste sensilla on the legs, and the expression pattern in the legs is conserved among closely related species. To identify the cis-regulatory elements necessary for the expression in the leg sensilla, the promoter sequences of Obp57d and Obp57e were compared among species. Two types of conserved sequence-motifs were found as candidate cis-regulatory elements. Functions of these conserved elements in the promoters of D. melanogaster Obp57d and Obp57e were examined by using a newly constructed vector that combines the advantages of φC31 integrase-based transformation and gypsy transposable-element-derived insulators. By GFP-reporter assay using the new vector, it was confirmed that these conserved elements are necessary for the expression in the legs, working synergistically with each other to affect the expression level. Single-nucleotide substitutions in these elements dramatically changed the promoter activity. These results provide insight into the molecular mechanism for evolution of adaptive behavior via modulation of OBP expression levels.
