During the 1990\u27s many "Poetry reading parties" were held in Tokyo, and many people enjoyed them. Recently, in the Kansai District, a similar "Poetry reading party" scheme was instituted. The "Poetry reading party" appeals to the narcissist, but from a viewpoint of "Poetry as Art", it serves no purpose. This essay is a manual of "Poetry reading", especially for beginners. However, as these people dislike training in "Poetry reading", this essay would be meaningless for them. Therefore this essay is paradoxical manual of "Poetry reading"

Estimation of Genetic Parameters, and Genetic and Environmental Effects on Progeny Carcass Traits of a Nucleus Breeding Population in Japanese Black Cattle

Genetic parameters of body weight at the start of fattening (BSF), carcass weight (CWT), subcutaneous fat thickness (SFT), rib thickness (RBT), meat quality grade (MQG), beef marbling score (BMS) and rib eye area (REA) in Japanese Black cattle were estimated. The effects of genetic and environmental factors on fattening performance and carcass quality traits of the progeny were also analyzed. The averages of BSF, CWT, SFT, RBT and REA were 189 kg, 408 kg, 24.9 mm, 69.3 mm and 47.5 cm^2, respectively. CWT was significantly affected (p<0.01) by sire, while BSF (p<0.01), CWT (p<0.01), SFT (p<0.01), RBT (p<0.01) and REA (p<0.05) were significantly affected by dam, indicating the scope of the applicability of selective breeding for improving the dam population for producing beef cattle with greater genetic ability to carcass traits. The sex of the calf had a significant (p<0.01 or p<0.05) effect on all the traits studied except REA. BSF, RBT, MQG and BMS were significantly (p<0.01) affected by the year and season of the birth of calves. The fattening farm exerted a significant influence (p<0.01) on BSF, CWT, MQG and BMS. The heritability estimates for BMS, CWT, RBT, BSF and MQG were 0.36, 0.34, 0.31, 0.26 and 0.23, respectively. Genetically, REA correlated negatively with BSF (-0.57) and SFT (-0.69), as did BMS with CWT (-0.35), SFT (-0.50) and RBT (-0.44). All the other traits correlated positively with one another

Integrated-gut-liver-on-a-chip platform as an in vitro human model of non-alcoholic fatty liver disease

非アルコール性脂肪性肝疾患を再現した腸・肝連結臓器チップの開発. 京都大学プレスリリース. 2023-04-07.Two-organ chip to answer fatty liver questions. 京都大学プレスリリース. 2023-04-07.Non-alcoholic fatty liver disease (NAFLD) afflicts a significant percentage of the population; however, no effective treatments have yet been established because of the unsuitability of in vitro assays and animal experimental models. Here, we present an integrated-gut-liver-on-a-chip (iGLC) platform as an in vitro human model of the gut-liver axis (GLA) by co-culturing human gut and liver cell lines interconnected via microfluidics in a closed circulation loop, for the initiation and progression of NAFLD by treatment with free fatty acids (FFAs) for 1 and 7 days, respectively. Co-cultured Caco-2 gut-mimicking cells and HepG2 hepatocyte-like cells demonstrate the protective effects from apoptosis against FFAs treatment, whereas mono-cultured cells exhibit induced apoptosis. Phenotype and gene expression analyses reveal that the FFAs-treated gut and liver cells accumulated intracellular lipid droplets and show an increase in gene expression associated with a cellular response to copper ions and endoplasmic reticulum stress. As an in vitro human GLA model, the iGLC platform may serve as an alternative to animal experiments for investigating the mechanisms of NAFLD

Isolation and characterization of a thermophilic, obligately anaerobic and heterotrophic marine Chloroflexi bacterium from a Chloroflexi dominated microbial community associated with a Japanese shallow hydrothermal system, and proposal for Thermomarinilinea lacunofontalis gen. nov., sp. nov.

A novel marine thermophilic and heterotrophic Anaerolineae bacterium in the phylum Chloroflexi, strain SW7T, was isolated from an in situ colonization system deployed in the main hydrothermal vent of the Taketomi submarine hot spring field located on the southern part of Yaeyama Archipelago, Japan. The microbial community associated with the hydrothermal vent was predominated by thermophilic heterotrophs such as Thermococcaceae and Anaerolineae, and the next dominant population was thermophilic sulfur oxidizers. Both aerobic and anaerobic hydrogenotrophs including methanogens were detected as minor populations. During the culture-dependent viable count analysis in this study, an Anaerolineae strain SW7T was isolated from an enrichment culture at a high dilution rate. Strain SW7T was an obligately anaerobic heterotroph grew with fermentation, and non-motile thin rods 3.5-16.5 μm in length and 0.2 μm in width constituting multicellular filament. Growth was observed between 37-65 ℃ (optimum 60℃), pH 5.5-7.3 (optimum pH 6.0), 0.5-3.5% (w/v) NaCl concentration (optimum 1.0%). Based on physiological and phylogenetic features of a new isolate, we propose a new species representing a novel genus Thermomarinilinea: the type strain of Thermomarinilinea lacunofontalis sp. nov., is SW7T (= JCM15506T = KCTC5908T)

Suppression of osteoclastogenesis via α2-adrenergic receptors

The sympathetic nervous system is known to regulate osteoclast development. However, the involvement of α2-adrenergic receptors (α2-ARs) in osteoclastogenesis is not well understood. In the present study, their potential role in osteoclastogenesis was investigated. Guanabenz, clonidine and xylazine were used as agonists of α2-ARs, while yohimbine and idazoxan were employed as antagonists. Using RAW264.7 pre-osteoclast and primary bone marrow cells, the mRNA expression of the osteoclast-related genes nuclear factor of activated T-cells, cytoplasmic 1 (NFATc1), tartrate-resistant acid phosphatase (TRAP) and cathepsin K was evaluated following induction with receptor activator of nuclear factor κB ligand (RANKL). TRAP staining was also conducted to assess effects on osteoclastogenesis in mouse bone marrow cells in vitro. Administration of 5-20 µM guanabenz (P<0.01, for RANKL-only treatment), 20 µM clonidine (P<0.05, for RANKL-only treatment) and 20 µM xylazine (P<0.05, for RANKL-only treatment) attenuated RANKL-induced upregulation of NFATc1, TRAP and cathepsin K mRNA. Furthermore, the reductions in these mRNAs by 10 µM guanabenz and 20 µM clonidine in the presence of RANKL were attenuated by 20 µM yohimbine or idazoxan (P<0.05). The administration of 5-20 µM guanabenz (P<0.01, for RANKL-only treatment) and 10-20 µM clonidine (P<0.05, for RANKL-only treatment) also decreased the number of TRAP-positive multi-nucleated osteoclasts. Collectively, the present study demonstrates that α2-ARs may be involved in the regulation of osteoclastogenesis
