삿갓이 완전히 펴진 표고버섯의 부위別에 따른 脂質의 特性과, 삿갓이 펴지지 않은 표고버섯의 乾燥方法에 따른 脂質의 變化를 硏究한 結果는 다음과 같다.<br/> 1. 삿갓이 펴진 표고버섯의 삿갓部位의 總脂質 含量은 4.58%이었고 자루部位는 2.6%이었으며 거의 大部分이 中性脂質(46.7~48.8%)과 憐脂質(42.0~43.8%)로 구성되어 있었으며 糖脂質은 적었다(9.2~9.5%)<br/> 2. 中性脂質의 主要成分은 tryacylglycerol이었고 憐脂質은 phosphatidyl ethanolamine이었다. 또한 脂質酸의 組成은 各脂質 및 部位에 따라 현격하게 달랐으며 C_(18:2), C_(16:1) 및 C_(18:1) 脂肪酸 順으로 含有되어 있었다.<br/> 3. 삿갓이 펴지지 않은 표고버섯의 總脂質은 2.5%(자루)~3.7%(삿갓)이었고 總脂質含量, 過酸化物價 및 카아보닐價는 乾燥方法에 따른 差異를 보이지 않았으며 總脂質의 酸價는 日乾試料가 生試料 및 熱風乾燥試料 보다 약간 낮았으나 日乾試料 中의 中性脂質含量은 다른 試料보다 높았다.<br/> 4. 가장 많은 部分을 차지한 中性 및 憐脂質의 主要成分의 삿갓이 완전히 펴진 표고버섯과 같았고 糖脂質은 digalactosyldiglycerol이었으며 日乾試料의 憐脂質中 phosphatidiyl ethanolamine과 phosphatidyl choline함량은 生試料 및 熱風乾燥試料보다 낮았다.<br/> 5. 모든 건조시료의 各 脂質 中의 主要 지방산조성은 삿갓이 펴진 시료의 경우와 비슷하였고 日乾試料의 C_(18:2) 脂肪酸함량은 다른 시료보다 높은 반면 C_(16:0) 지방산은 낮았다. 한편일건시료 중의불포화지방산 함량은 열풍건조시료 및 生시료보다 낮았다. The properties of lipids in cap and stalk of "Koshin" (Shiitake, Lentinus edodes, withxpanded cap) were studied. It was also carried out that the characteristics of lipids in fresh "Donko"(unexpanded cap) and the changes of lipids in those samples by various drying process. The total lipid (TL) content in the cap and stalk of "Koshin" were 4.58% and 2.65% respectively. It was found that the contents of neutral lipids (NL, 46.7~48.8%) and phospholipids (PL, 42.0~43.8%) were high, while that of glycolipids(GL, 9.2~9.5%) was low. The main lipid in NL was triacylglycerol (TG, 58.0~58.5%) followed by sterolester (SE, 16.9~17.4%), sterol (ST, 15.6~16.4%), diacylglycerol (DG, 5.8~6.0%) and monoacylglcerol (MG, 1.1~1.3%). The main lipids in PL was phosphatidyl ethanolamine (PE, 58.3~6.02%) followed by phosphatidyl choline (PC, 17.3~19.5%), cardiolipin (CA, 12.8~14.0%) and lyso-phophatidyl choline (LPD, 4.8~6.6%). Fatty acid composition was significantly different among TL, NL, GL and PL contained in cap and stalk. The main fatty acids was C_(18:2) followed by C_(16:0) and C_(18:1) acids. The TL contents in cap and stalk of fresh "Donko" were 3.7% and 2.5%. The changes of TL contents, PoV by drying were not almost observed. AV(acid value) of TL in the sun dried samples was a little lower than those of the fresh and hot air dried samples, on the contrary NL content in TL of the former was a little higher than those of the latters. The main lipid in NL of the three samples was TG followed by SE, ST, DG, MG and free fatty acid (FFA). In the above lipids, FFA contents in NL of the sun dried sample was a little higher than those of the fresh and hot air dried samples, but TG content in NL of former was a little lower than those of the latters. The main lipid in GL of the three samples was digalactosydiglycerol (DGDG) followed by acylsterylglucoside(ASG), sterylglucoside (SG), monogalactosyldiglycerol (MGD) and cerebroside (CER). Influence of drying on these lipid content were nol almost recognized. The main lipid in PL of the three samples was PE followed by PC, CA, LPC and phosphat idyl serine (PS). In the above lipids, PE and PC contents in PL of the sun dried one were a little lower than those of the fresh and hot air dried ones. The main fatty acid in TL, NL, GL and PL of the three samples was C_(18:2) followed by C_(16:0), C_(18:1). The C_(18:2) acid contents of the sun dried sample was a little lower than those of the fresh and hot air dried ones, while C_(16:0) content of the former was a little higher than those of the former was a little lower than those of the latters.

Aoyagi, Kota,Tsuyuki, Satoshi,Phua, Mui-How,Teo, Stephen Institute of Forest Science 2012 Journal of Forest Science Vol.28 No.3

Dipterocarps (Dipterocarpaceae) is a dominant tree family of tropical rainforest in Southeast Asia. Dipterocarps have been exploited for its timber and disappearing fast in East Kalimantan. In this study, we predicted the distribution of dipterocarpus, one of the main dipterocarps genera, by evaluating its habitat suitability using logistic regression analysis with specimen collection points and environmental factors from GIS data. Current distribution of dipterocarpus was generated by combining the habitat suitability classes with an updated forest cover map. Rainfall, soil type, followed by elevation was the main factors that influence the distribution of dipterocarpus in East Kalimantan. Dipterocarpus can be found in a quarter of the current forest cover, which is highly suitable as habitat of Dipterocarpus.

Prevalence of Complement-Mediated Cell Lysis-like Gene (sicG) in Streptococcus dysgalactiae subsp. equisimilis Isolates From Japan (2014–2016)

Takashi Takahashi,Tomohiro Fujita,Akiyoshi Shibayama,Yuzo Tsuyuki,Haruno Yoshida 대한진단검사의학회 2017 Annals of Laboratory Medicine Vol.37 No.4

Background: Streptococcus dysgalactiae subsp. equisimilis (SDSE; a β-hemolytic streptococcus of human or animal origin) infections are emerging worldwide. We evaluated the clonal distribution of complement-mediated cell lysis-like gene (sicG) among SDSE isolates from three central prefectures of Japan. Methods: Group G/C β-hemolytic streptococci were collected from three institutions from April 2014 to March 2016. Fifty-five strains (52 from humans and three from animals) were identified as SDSE on the basis of 16S rRNA sequencing data.; they were obtained from 25 sterile (blood, joint fluid, and cerebrospinal fluid) and 30 non-sterile (skin-, respiratory tract-, and genitourinary tract-origin) samples. emm genotyping, multilocus sequence typing, sicG amplification/sequencing, and random amplified polymorphic DNA (RAPD) analysis of sicG-positive strains were performed. Results: sicG was detected in 30.9% of the isolates (16 human and one canine) and the genes from the 16 human samples (blood, 10; open pus, 3; sputum, 2; throat swab, 1) and one canine sample (open pus) showed the same sequence pattern. All sicG-harboring isolates belonged to clonal complex (CC) 17, and the most prevalent emm type was stG6792 (82.4%). There was a significant association between sicG presence and the development of skin/soft tissue infections. CC17 isolates with sicG could be divided into three subtypes by RAPD analysis. Conclusions: CC17 SDSE harboring sicG might have spread into three closely-related prefectures in central Japan during 2014–2016. Clonal analysis of isolates from other areas might be needed to monitor potentially virulent strains in humans and animals.

Sire-maternal Grandsire Model and Sire Model in Estimation of Genetic Parameters for Average Daily Gain and Carcass Traits of Japanese Black Cattle

Kim, Jong-Bok,Lee, Chaeyoung,Tsuyuki, Tsutomu,Shimogiri, Takeshi,Okamoto, Shin,Maeda, Yoshizane Asian Australasian Association of Animal Productio 2006 Animal Bioscience Vol.19 No.12

The objectives of this study were to estimate genetic parameters and sire breeding values for average daily gain (ADG) and carcass traits using sire-maternal grandsire model with REML approach, sire model with REML approach, sire model without relationships among sires and with REML and ANOVA approach, and to investigate advantages and disadvantages of these methods. Data were collected from 42,325 Japanese Black steers and heifers finished and slaughtered from 1991 to 2004. Traits analyzed in this study were average daily gain (ADG) during the fattening period, live weight at slaughter (LW), cold carcass weight (CW), estimated lean yield percentage (LYE), longissimus muscle area (LMA), subcutaneous fat thickness (SFT), rib thickness (RT), and marbling score (BMS). Bivariate analyses were also performed to obtain genetic and phenotypic correlation coefficients among traits. Estimated breeding values were obtained from each model, and simple and rank correlations among breeding values from each model were calculated. Estimates of heritability using the four models ranged from 0.25 to 0.31 in ADG, from 0.21 to 0.24 in LW, from 0.23 to 0.27 in CW, from 0.10 to 0.17 in DP, from 0.40 to 0.42 in LYE, from 0.19 to 0.31 in LMA, from 0.31 to 0.34 in SFT, from 0.26 to 0.33 in RT, and from 0.18 to 0.44 in BMS. The differences in heritability estimates using the four models seemed to be feasible in ADG, CW, DP, LMA, RT, and BMS. Genetic correlation coefficients of ADG with CW, SFT, RT and BMS were moderate to high and positive while the genetic correlation coefficients between ADG and LYE was low and negative. Correlation coefficients of BMS with SFT were negligible for both genetic and phenotypic correlations. The correlations of estimates evaluated from sire models with those from sire-maternal grandsire model were not large enough to convincing that breeding values using a sire model were corresponding to those using a sire-maternal grand sire model. If information of maternal grand sires are not available, the sire model with incomplete pedigree information included only sire of sire (Model 2) is optimal among the sire models evaluated in this study.
