Soil Carbon in Agroforestry Systems: An Unexplored Treasure?

Soil organic matter (SOM), which contains more reactive organic carbon (C) than any other single terrestrial pool, plays a major role in determining C storage in ecosystems and regulating atmospheric concentrations of carbon dioxide (CO2)^1^. Agroforestry, the practice of growing trees and crops in interacting combinations on the same unit of land^2^, primarily by resource-poor smallholder farmers in developing countries, is recognized as a strategy for soil carbon sequestration (SCS) under the Clean Development Mechanism (CDM) of the Kyoto Protocol^3^. The understanding about C storage and dynamics under agroforestry systems (AFS), however, is minimal. Our studies under various AFS in diverse ecological conditions in five countries showed that tree-based agricultural systems, compared to treeless systems, stored more C in deeper soil layers up to 1 m depth under comparable conditions. More C is stored in soil near the tree than away from the tree; higher SOC content is associated with higher species richness and tree density; and C3 plants (trees) contribute to more C in the silt- + clay-sized (<53 µm) fractions that constitute more stable C, than C4 plants, in deeper soil profiles4 - 8. These results provide clear indications of the possibilities for climate change mitigation through SCS in AFS, and opportunities for economic benefit - through carbon trading - to millions of smallholder farmers in developing countries

Saizu: A Very Big Loanword in Japanese

The tradition of student-centered active learning for development of critical thinking at Miyazaki International College provides valuable opportunities for discovery in the classroom. This brief paper outlines the results of one such student project in LL3141, Topics in Linguistics, taught by Debra J Occhi in fall semester of 2013. Students were inspired to undertake this research while reading and discussing Language Contact Meets Cognitive Linguistics: A Case of Getto-suru in Japanese (Horie & Occhi 2001). This paper reviews those findings, presents issues students found especially relevant about loanword behavior discussed in Olah (2007) and about English made in Japan (wasei eigo, discussed in Miller 1997), lists noun loanwords found in Japanese-English dictionaries, presents and analyzes instances of use of the loanword saizu (from English “size”)

マウスの胸腺と脾臓におけるIgE転写の比較

1週齢から5週齢BALB/cマウスの抗体遺伝子の転写を,胸腺と脾臓で比較した。調べた抗体のクラスのなかで,IgEの転写量に関しては,胸腺と脾臓で明瞭な差異が認められた。胸腺では,雌雄ともに,IgEは1週齢から転写されていた。脾臓では3週齢までは検出できなかった。雌では,3週齢から4週齢の間で,脾臓でもIgEの転写が検出され始めた。雄では,5週齢まででは,脾臓でIgEの転写は検出できなかった。IgEの転写に関して胸腺と脾臓で明瞭な差異が認められることから,胸腺で抗体遺伝子を転写している細胞は,胸腺内の血管内のBリンパ球ではなく,また,脾臓で分化したBリンパ球が流入したものでもなく,発生段階で流入した幹細胞から胸腺内で分化したリンパ球であると考えられる。Immunoglobulin heavy chain gene transcription was investigated by reverse transcription PCR both in the thymus and in the spleen of BALB/c mice of age 1 to 5 weeks old. A definitive difference in IgE transcriptions was found between in the thymus and in the spleen. IgE transcriptions were demonstrated clearly in the thymus of all mice, while, in the spleen, not detected in 1 to 3 weeks old. Therefore, the cells transcribing antibody genes in the thymus of mouse are neither B lymphocytes in blood vessels, nor invaded B lymphocytes after proliferation and development in the spleen. Those will be specific cells which proliferate and develop in the thymus from stem cells which immigrated at embryonic stage

The Japanese Clinical Practice Guidelines for Management of Sepsis and Septic Shock 2016 (J-SSCG 2016)

Background and purposeThe Japanese Clinical Practice Guidelines for Management of Sepsis and Septic Shock 2016 (J-SSCG 2016), a Japanese-specific set of clinical practice guidelines for sepsis and septic shock created jointly by the Japanese Society of Intensive Care Medicine and the Japanese Association for Acute Medicine, was first released in February 2017 and published in the Journal of JSICM, [2017; Volume 24 (supplement 2)] https://doi.org/10.3918/jsicm.24S0001 and Journal of Japanese Association for Acute Medicine [2017; Volume 28, (supplement 1)] http://onlinelibrary.wiley.com/doi/10.1002/jja2.2017.28.issue-S1/issuetoc.This abridged English edition of the J-SSCG 2016 was produced with permission from the Japanese Association of Acute Medicine and the Japanese Society for Intensive Care Medicine.MethodsMembers of the Japanese Society of Intensive Care Medicine and the Japanese Association for Acute Medicine were selected and organized into 19 committee members and 52 working group members. The guidelines were prepared in accordance with the Medical Information Network Distribution Service (Minds) creation procedures. The Academic Guidelines Promotion Team was organized to oversee and provide academic support to the respective activities allocated to each Guideline Creation Team. To improve quality assurance and workflow transparency, a mutual peer review system was established, and discussions within each team were open to the public. Public comments were collected once after the initial formulation of a clinical question (CQ) and twice during the review of the final draft. Recommendations were determined to have been adopted after obtaining support from a two-thirds (> 66.6%) majority vote of each of the 19 committee members.ResultsA total of 87 CQs were selected among 19 clinical areas, including pediatric topics and several other important areas not covered in the first edition of the Japanese guidelines (J-SSCG 2012). The approval rate obtained through committee voting, in addition to ratings of the strengths of the recommendation, and its supporting evidence were also added to each recommendation statement. We conducted meta-analyses for 29 CQs. Thirty-seven CQs contained recommendations in the form of an expert consensus due to insufficient evidence. No recommendations were provided for five CQs.ConclusionsBased on the evidence gathered, we were able to formulate Japanese-specific clinical practice guidelines that are tailored to the Japanese context in a highly transparent manner. These guidelines can easily be used not only by specialists, but also by non-specialists, general clinicians, nurses, pharmacists, clinical engineers, and other healthcare professionals

Complications of Non-Alcoholic Fatty Liver Disease in Extrahepatic Organs

Non-alcoholic fatty liver disease (NAFLD) is now recognized as the most common chronic liver disease worldwide, along with the concurrent epidemics of metabolic syndrome and obesity. Patients with NAFLD have increased risks of end-stage liver disease, hepatocellular carcinoma, and liver-related mortality. However, the largest cause of death among patients with NAFLD is cardiovascular disease followed by extrahepatic malignancies, whereas liver-related mortality is only the third cause of death. Extrahepatic complications of NAFLD include chronic kidney disease, extrahepatic malignancies (such as colorectal cancer), psychological dysfunction, gastroesophageal reflux disease, obstructive sleep apnea syndrome, periodontitis, hypothyroidism, growth hormone deficiency, and polycystic ovarian syndrome. The objective of this narrative review was to summarize recent evidences about extrahepatic complications of NAFLD, with focus on the prevalent/incident risk of such diseases in patients with NAFLD. To date, an appropriate screening method for extrahepatic complications has not yet been determined. Collaborative care with respective experts seems to be necessary for patient management because extrahepatic complications can occur across multiple organs. Further studies are needed to reveal risk profiles at baseline and to determine an appropriate screening method for extrahepatic diseases
