The investigation into the energy consumption in some Japanese fisheries and the measures to reduce CO2 emissions

Japan’s fish production volume in 2008 was 5.59million tons, it accounted for 4% of world’s production and consisted of catch (4.40million tons) and aquaculture (1.19 million tons). For the far sea fishery, its’ fishing grounds are in domestic and foreign countries’ exclusive economic zone and international waters, since the total production volume of this fishery has been declining, offshore and coastal fishery have become mainly in Japan. In this study, the estimation of the energy consumptions in a kelp aquaculture and three types of fisheries, such as squid, fixed net and gill net, is done for comparison to the consumptions of fisheries in foreign countries. The result reveals that the characteristics of these fisheries’ energy consumptions and the measures for reductions of energy use. Furthermore, in Minamikayabe as surveyed fishing village, the carbon dioxide balance in this village is evaluated. The carbon dioxide emissions from the energy (fuel and electricity) use and the escape Chlorofluorocarbons (CFCs) and Hydrochlorofluorocarbons (HCFCs) from freezers, refrigerators and ice manufacture machines in the village are calculated. Meanwhile, as forests and oceans are carbon dioxide sinks, it is possible to estimate the volume of carbon dioxide stored by woods and seaweed along the coast. Finally, several measures for carbon dioxide reductions are shown.

A Point Mutation of Tyr-759 in Interleukin 6 Family Cytokine Receptor Subunit gp130 Causes Autoimmune Arthritis

We generated a mouse line in which the src homology 2 domain–bearing protein tyrosine phosphatase (SHP)-2 binding site of gp130, tyrosine 759, was mutated to phenylalanine (gp130F759/F759). The gp130F759/F759 mice developed rheumatoid arthritis (RA)-like joint disease. The disease was accompanied by autoantibody production and accumulated memory/activated T cells and myeloid cells. Before the disease onset, the T cells were hyperresponsive and thymic selection and peripheral clonal deletion were impaired. The inhibitory effect of IL-6 on Fas ligand expression during activation-induced cell death (AICD) was augmented in gp130F759/F759 T cells in a manner dependent on the tyrosine residues of gp130 required for signal transducer and activator of transcription 3 activation. Finally, we showed that disease development was dependent on lymphocytes. These results provide evidence that a point mutation of a cytokine receptor has the potential to induce autoimmune disease

Comparison of severity classification in Japanese patients with antineutrophil cytoplasmic antibody-associated vasculitis in a nationwide, prospective, inception cohort study

OBJECTIVE: To compare disease severity classification systems for six-month outcome prediction in patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). METHODS: Patients with newly diagnosed AAV from 53 tertiary institutions were enrolled. Six-month remission, overall survival, and end-stage renal disease (ESRD)-free survival were evaluated. RESULTS: According to the European Vasculitis Study Group (EUVAS)-defined disease severity, the 321 enrolled patients were classified as follows: 14, localized; 71, early systemic; 170, generalized; and 66, severe disease. According to the rapidly progressive glomerulonephritis (RPGN) clinical grading system, the patients were divided as follows: 60, grade I; 178, grade II; 66, grade III; and 12, grade IV. According to the Five-Factor Score (FFS) 2009, 103, 109, and 109 patients had ≤1, 2, and ≥3 points, respectively. No significant difference in remission rates was found in any severity classification. The overall and ESRD-free survival rates significantly differed between grades I/II, III, and IV, regardless of renal involvement. Severe disease was a good predictor of six-month overall and ESRD-free survival. The FFS 2009 was useful to predict six-month ESRD-free survival but not overall survival. CONCLUSIONS: The RPGN grading system was more useful to predict six-month overall and ESRD-free survival than the EUVAS-defined severity or FFS 2009

Theorising about mathematics teachers\u27 professional knowledge: The content, form, nature, and source of teachers\u27 knowledge

The guiding philosophy of this theoretical work lays in the argument that mathematics_teachers’ professional knowledge is the integration of various knowledge facets derived_from different sources including teaching experience and research. This paper goes beyond_past trends identifying what the teachers’ knowledge is about (content) by providing new_perspectives, in particular, on how the knowledge is structured and organised (form), on_what teachers’ draw on their knowledge (source), and whether the knowledge is stable and_coherent or contextually-sensitive and fluid (nature)
