Non-randomized controlled trial examining the effects of livestock on motivation and anxiety in patients with chronic psychiatric disorders.

Objectives: Patients with chronic schizophrenia exhibit negative symptoms, including decreased work motivation. Animal-assisted therapy programs have been reported to benefit such patients; hence, there is a possibility that sheep-rearing, rather than conventional employment training, may motivate these patients. Therefore, we investigated the effects of a one-day experiential learning program of sheep-rearing on the work motivation and anxiety of patients with chronic schizophrenia.

Effect of climatic factors on urinary cortisol and peripheral blood leukocytes in lambs grazing on a semi-natural grassland in the Hokuriku District of Japan.

The effects of climatic factors on stress and immune functions of grazing lambs in summer and autumn in the Hokuriku District of Japan were evaluated by determining urinary cortisol (U-COR) levels and peripheral blood leukocyte populations and comparing those with lambs kept indoors. Two groups of five lambs, consisting of those grazed on a semi-natural grassland (GRL) and those housed indoors in a domestic animal shelter (INL), were maintained at from July to October. The temperature-humidity index at each location was indicative of heat stress during summer; however, the U-COR elevation was not observed in both groups.

Generation of reconstituted hemato-lymphoid murine embryos by placental transplantation into embryos lacking HSCs.

In order to increase the contribution of donor HSC cells, irradiation and DNA alkylating agents have been commonly used as experimental methods to eliminate HSCs for adult mice. But a technique of HSC deletion for mouse embryo for increase contribution of donor cells has not been published. Here, we established for the first time a procedure for placental HSC transplantation into E11.

Improving quality of common reed (Phragmites communis Trin.) silage with additives.

Objective: Common reed (Phragmites communis Trin.) could potentially provide an alternative resource for silage; however, its silage quality is poor. The aim of this study was to investigate the factors in reed that contribute to poor quality and determine how the use of additives at ensiling could improve fermentation quality.

MafB is a critical regulator of complement component C1q.

The transcription factor MafB is expressed by monocytes and macrophages. Efferocytosis (apoptotic cell uptake) by macrophages is important for inhibiting the development of autoimmune diseases, and is greatly reduced in Mafb-deficient macrophages. Here, we show the expression of the first protein in the classical complement pathway C1q is important for mediating efferocytosis and is reduced in Mafb-deficient macrophages.

Digestibility of common reed (Pharagmites communis Trin.) silage as ruminant feed and effects of inclusion levels in the diet of breeding cows on feed intake, ruminal fermentation and blood metabolites.

To examine the digestibility of common reed (Pharagmites communis Trin.) silage and effects of inclusion levels in the diet of breeding cows on nutrient intakes, ruminal fermentation and nutrient status, two digestion trials using four sheep and cows, respectively, at the maintenance stage were conducted. In the trial using sheep, common reed silage contained 20% crude protein (CP) and 50% total digestible nutrients (TDN) on a dry matter basis.

Diversity in VP3, NSP3, and NSP4 of rotavirus B detected from Japanese cattle.

Bovine rotavirus B (RVB) is an etiological agent of diarrhea mostly in adult cattle. Currently, a few sequences of viral protein (VP)1, 2, 4, 6, and 7 and nonstructural protein (NSP)1, 2, and 5 of bovine RVB are available in the DDBJ/EMBL/GenBank databases, and none have been reported for VP3, NSP3, and NSP4. In order to fill this gap in the genetic characterization of bovine RVB strains, we used a metagenomics approach and sequenced and analyzed the complete coding sequences (CDS) of VP3, NSP3, and NSP4 genes, as well as the partial or complete CDS of other genes of RVBs detected from Japanese cattle.

Identification of further diversity among posaviruses.

Recently, there have been reports of new members of posavirus-like viruses in the order Picornavirales. In this study, using a metagenomics approach, 11 posavirus-like sequences (>7,000 nucleotides) were detected in 155 porcine fecal samples. Phylogenetic analysis revealed that the newly identified virus sequences, together with other posavirus-like viruses, form distinct clusters within the order Picornavirales, composed of eight genogroups and unassigned sequences based on amino acid sequences of the helicase and RNA-dependent RNA polymerase regions, with <40 % and <50 % sequence identity, respectively.

Effects of inclusion levels of pelleted silvergrass (Miscanthus sinensis Andress.) in the diet on digestibility, chewing activity, ruminal fermentation and blood metabolites in breeding Japanese Black cows.

To examine the effects of inclusion levels of pelleted silvergrass (PS) in the diet on digestibility, ruminal fermentation and nutrient status of breeding Japanese Black cows, four cows were allotted to a 4 × 4 Latin square design experiment. Treatments were control fed a diet consisting of 89.4% Sudangrass hay and 10.

Ground-based assessment of JAXA mouse habitat cage unit by mouse phenotypic studies.

The Japan Aerospace Exploration Agency developed the mouse Habitat Cage Unit (HCU) for installation in the Cell Biology Experiment Facility (CBEF) onboard the Japanese Experimental Module ("Kibo") on the International Space Station. The CBEF provides "space-based controls" by generating artificial gravity in the HCU through a centrifuge, enabling a comparison of the biological consequences of microgravity and artificial gravity of 1 g on mice housed in space. Therefore, prior to the space experiment, a ground-based study to validate the habitability of the HCU is necessary to conduct space experiments using the HCU in the CBEF.
