Background: Shoulder horizontal adduction (HA) is performed in many activities of daily living. The limited range of motion (LROM) of HA is affected by the tightness of the posterior deltoid, infraspinatus, teres major, and posterior capsule of glenohumeral joint. The LROM of shoulder HA contributes to excessive scapular abduction. Objects: The aim of this study is to compare the scapular abduction distance and three dimensional displacement of the scapula during shoulder horizontal adduction between subjects with and without the LROM of shoulder HA. Methods: 24 subjects (12 people in LROM group and 12 people in normal ROM group) participated. Subjects with less than 115° of HA ROM were included in LROM group. Shoulder HA was performed 3 times for measuring scapular abduction distance and three-dimensional displacement of the scapula. Tape measure was used for measuring scapular abduction distance. Scapular abduction distance was normalized by dividing the scapular size. Polhemus Liberty was used for measuring the three dimensional displacement of the scapula. Results: Normalized scapular abduction distance was significantly greater in LROM group than normal ROM group (p<.001). Three-dimensional displacement of the scapula during shoulder HA was greater in LROM group than normal ROM group (p<.05). Conclusion: LROM group had a greater scapular abduction and three-dimensional displacement of the scapula during shoulder HA compared to normal ROM group.

Background: Standing biomass, litter production, rate of litter decomposition, amount of litter on forest floor, and amount of soil organic carbon distribution were investigated from March 2016 to November 2018 in order to evaluate the ecosystem value through organic carbon distribution in the Pinus densiflora forest at Namsan, Seoul Metropolitan City. Results: The amount of organic carbon in the Pinus densiflora forest was 261.09 ton C ha^-1 during the research period, and fixed organic carbon in plant through net photosynthesis was 3.2 ton C ha^-1 year^-1. The organic carbon in plant was 62.77 ton C ha^-1 (24.04%), in litter on the forest floor was 3.65 ton C ha^-1 (1.40%), and in soil was 194.67 ton C ha^-1 (74.56%). The value of plant, litter on forest floor, and soil organic carbon distribution were each 6,277,000 won ha^-1, 365, 000 won ha^-1, and 19,467,000 won ha^-1. The value per ton of fixed organic carbon in plant through net photosynthesis was 320,000 won ha^-1 year^-1 and the value of ecosystem services stored in carbon in the Namsan forest ecosystem was about 26.1 million won ha^-1 for 3 years. Conclusions: The results of this study suggest that the pine forests of Namsan rapidly decompose leaves due to the high atmospheric temperature and accumulate a large amount of organic carbon in the soil to provide climate control regulatory service function.

Ha ,, Seongmin,Kim ,, Jae‐,Kwang,Choi, Aram,Kim, Youngsik,Lee, Kyu Tae WILEY‐VCH Verlag 2014 ChemPhysChem Vol.15 No.10

<P>Impressive developments have been made in the past a few years toward the establishment of Na-ion batteries as next-generation energy-storage devices and replacements for Li-ion batteries. Na-based cells have attracted increasing attention owing to low production costs due to abundant sodium resources. However, applications of Na-ion batteries are limited to large-scale energy-storage systems because of their lower energy density compared to Li-ion batteries and their potential safety problems. Recently, Na-metal cells such as Na-metal halide and Na-air batteries have been considered to be promising for use in electric vehicles owing to good safety and high energy density, although less attention is focused on Na-metal cells than on Na-ion cells. This Minireview provides an overview of the fundamentals and recent progress in the fields of Na-metal halide and Na-air batteries, with the aim of providing a better understanding of new electrochemical systems.</P>

Reports : Structure-activity relationships of the intramolecular disulfide bonds in coprisin, a defensin from the dung beetle

( Jae Ho Lee ),( Da Eun Lee ),( Hye Min Choi ),( Ha Hyung Kim3 ),( Ho Kim ),( Jae Sam Hwang ),( Dong Gun Lee ),( Jae Il Kim ) 생화학분자생물학회 2014 BMB Reports Vol.47 No.11

Defensins, which are small cationic molecules produced by organisms as part of their innate immune response, share a common structural scaffold that is stabilized by three disulfide bridges. Coprisin is a 43-amino acid defensin-like peptide from Copris tripartitus. Here, we report the intramolecular disulfide connectivity of cysteine-rich coprisin, and show that it is the same as in other insect defensins. The disulfide bond pairings of coprisin were determined by combining the enzymatic cleavage and mass analysis. We found that the loss of any single disulfide bond in coprisin eliminated all antibacterial, but not antifungal, activity. Circular dichroism (CD) analysis showed that two disulfide bonds, Cys20-Cys39 and Cys24- Cys41, stabilize coprisin’s α-helical region. Moreover, a BLAST search against UniProtKB database revealed that coprisin’s α-helical region is highly homologous to those of other insect defensins. [BMB Reports 2014; 47(11): 625-630]

Changes of the spectroscopic characteristics of the organic matter fractions and circular filter paper chromatograph were assessed for the bark and piggery manure composts during the composting. as an approach to base the criteria of the compost maturity evaluation. Contents of humic acid-C (HA-C) and fulvic acid-C (FA-C) in both bark and piggery manure composts were decreased as the composting got closer to maturity, but the ratios of HA-C/FA-C were increased. During the composting. Δlog K values were decreased, but RF values were increased. Humic acid of the mature bark compost after 120 days of composting was A-type, as compared to Rp-type for the raw bark and B-type for the immature compost. However. humic acid of the mature piggery manure composts after 40 days of composting was B-type, indicating the humification of the organic matter fractions continued at this stage. Circular filter paper chromatograph of the mature bark compost exhibited the regular sawteeth pattern at the edge, but that of the mature piggery manure showed an irregular sawteeth pattern. Results demonstrated that spectroscopic characteristics and circular filter paper chromatograph of the organic by-product composts might be employed for the compost stability assessment.

Background: Progastrin-releasing peptide (proGRP) is a recently identified biomarker of small cell lung cancer (SCLC). We aimed this study for evaluating the usefulness of automated proGRP measurement for diagnosis and treatment monitoring in patients with SCLC. Methods: From January 2011 to December 2013, plasma samples were prospectively collected from 452 [213 non-small cell lung cancer (NSCLC), 104 SCLC, 135 other diseases] patients visited for tissue diagnosis and tested by two-step automated immunoassay using the ARCHITECT proGRP assay kit (Abbott Diagnostics, USA). The cutoff level of proGRP was set at 63 pg/mL. Results: The mean proGRP was higher in SCLC (1823.0 ± 2684.0 pg/mL) than in NSCLC (61.0 ± 341.7 pg/mL) and other diseases (51.5 ± 222.6 pg/mL, p<0.001). The sensitivity of proGRP was 85.7% (90/105) in SCLC and 11.8% (25/212) in NSCLC. The specificity was 90.2%, positive predictive value was 72.5%, and negative predictive value was 95.4% in SCLC. The mean proGRP was higher in extensive disease (2158.1 ± 2980.6 pg/mL) than in limited disease (901.4 ± 1216.0 pg/mL, p=0.033). Among the 39 patients with SCLC could be followed, the mean proGRP levels of 23 responders were significantly decreased after chemotherapy (from 1651.5 ± 1386.4 pg/mL to 290.0 ± 524.8 pg/mL, p<0.001), whereas those of the 16 non-responders were not. (from 572.5 ± 790.3 pg/mL to 494.4 ± 610.9 pg/mL, p=0.583). Conclusion: Plasma proGRP could be a useful biomarker of SCLC for diagnosis and treatment monitoring. And the initial level may represent the tumor extent of SCLC.

The delivery of the proper care to the emergency dental patients is more important in the aspdect of community dental service. To attain such a purpose requires the sacred duty to the training of oral and maxillofacial surgeons. This is a retrospective study on the characteristics of dental injuries and diseases in emergency patients. Ths study was based on a series of 2,649 patients treated as dental emergency patients at K country hospital of medical college, from Jan. 1, 1993, to Dec. 31, 2000. The obtained results were as follows. The trauma(71.6%) was the most frequent cause in dental emergency patients, odontogenic infection and oral hemorrhage were next in order of frequency. The primary interdental wiring and transpalatal wiring were frequent proper methods with rubber drainage for prevention of hemorrhage and infection in the primary care of jaw fracture. The peak incidence(45.0%) about the infection group was occurred in the pulpitis of advanced dental caries, and common treatments were the medication of antibiotics & anagesics and I&D. In the dentoalveolar hemorrhage group, a major cause was postoperative hemorrhage(57.9%) and hemostasis was obtained by pressure dressing, suture and drainage of infected wound. About TMJ disorder group, the peak incidence was showed in the post-traumatic myofascial pain dysfunction syndrome and its primary care was medications(anagesics & sedatives). In the other groups, various irritable specific pains were complained, such as trigeminal neuralgia-form pain, acute stomatitis, chemical burn, terminal stage neuritis of head & nech cancer and their primary care methods were various individually. For the rapid and correct care of the emergency dental disease above, well-trained education should be presented in the intern and resident curriculum of oral & maxillofacial surgery.

Son, Jun Seong,Song, Jae-Hoon,Ko, Kwan Soo,Yeom, Joon Sup,Ki, Hyun Kyun,Kim, Shin-Woo,Chang, Hyun-Ha,Ryu, Seong Yeol,Kim, Yeon-Sook,Jung, Sook-In,Shin, Sang Yop,Oh, Hee Bok,Lee, Yeong Seon,Chung, Doo The Korean Academy of Medical Sciences 2010 JOURNAL OF KOREAN MEDICAL SCIENCE Vol.25 No.7

<P>Recent changes in healthcare systems have changed the epidemiologic paradigms in many infectious fields including bloodstream infection (BSI). We compared clinical characteristics of community-acquired (CA), hospital-acquired (HA), and healthcare-associated (HCA) BSI. We performed a prospective nationwide multicenter surveillance study from 9 university hospitals in Korea. Total 1,605 blood isolates were collected from 2006 to 2007, and 1,144 isolates were considered true pathogens. HA-BSI accounted for 48.8%, CA-BSI for 33.2%, and HCA-BSI for 18.0%. HA-BSI and HCA-BSI were more likely to have severe comorbidities. <I>Escherichia coli</I> was the most common isolate in CA-BSI (47.1%) and HCA-BSI (27.2%). In contrast, <I>Staphylococcus aureus</I> (15.2%), coagulase-negative <I>Staphylococcus</I> (15.1%) were the common isolates in HA-BSI. The rate of appropriate empiric antimicrobial therapy was the highest in CA-BSI (89.0%) followed by HCA-BSI (76.4%), and HA-BSI (75.0%). The 30-day mortality rate was the highest in HA-BSI (23.0%) followed by HCA-BSI (18.4%), and CA-BSI (10.2%). High Pitt score and inappropriate empirical antibiotic therapy were the independent risk factors for mortality by multivariate analysis. In conclusion, the present data suggest that clinical features, outcome, and microbiologic features of causative pathogens vary by origin of BSI. Especially, HCA-BSI shows unique clinical characteristics, which should be considered a distinct category for more appropriate antibiotic treatment.</P>
