We analyzed the chirp sound and behavior of Teleogryllus emma with observation system, which was consisted of computer, ccd-camera and microphone. Computational methods of wavelet transformation and Self-Organizing Maps (SOM) were utilized to characterized the chirp sound of insect species for automatic counting in this study. Wavelets were initially applied to feature extraction of the chirp sound. Wavelet coefficients were accordingly calculated based on the basis function (e.g., Morlet). The obtained coefficients were subsequently provided to count number of chirps in each song. Sound structure of insect specimens consisted with long chirp and short chirp and the patterns of song were grouped by frequency of long chirp and short chirp. The song patterns of insect specimens were divided by Self-Organizing Map (SOM) that was used number of chirp as input data. Application of computational methods to automatic detection of chirp sound was further discussed for obtaining objective assessment in behavior science.

Identification of a sensitive urinary biomarker, selenium-binding protein 1, for early detection of acute kidney injury

Kim, Kyeong Seok,Yang, Hun Yong,Song, Hosup,Kang, Ye Rim,Kwon, JiHoon,An, JiHye,Son, Ji Yeon,Kwack, Seung Jun,Kim, Young-Mi,Bae, Ok-Nam,Ahn, Mee-Young,Lee, Jaewon,Yoon, Sungpil,Lee, Byung μ,Kim, Hyung TAYLOR & FRANCIS 2017 Journal of Toxicology and Environmental Health Vol.80 No.9

<P>Acute kidney injury (AKI) is associated with increased mortality rate in patients but clinically available biomarkers for disease detection are currently not available. Recently, a new biomarker, selenium-binding protein 1 (SBP1), was identified for detection of nephrotoxicity using proteomic analysis. The aim of this study was to assess the sensitivity of urinary SBP1 levels as an early detection of AKI using animal models such as cisplatin or ischemia/reperfusion (I/R). Sprague-Dawley rats were injected with cisplatin (6 mg/kg, once i.p.) and sacrificed at 1, 3, or 5 days after treatment. Ischemia was achieved by bilaterally occluding both kidneys with a microvascular clamp for 45 min and verified visually by a change in tissue color. After post-reperfusion, urine samples were collected at 9, 24, and 48 hr intervals. Urinary excretion of protein-based biomarkers was measured by Western blot analysis. In cisplatin-treated rats, mild histopathologic alterations were noted at day 1 which became severe at day 3. Blood urea nitrogen (BUN) and serum creatinine (SCr) levels were significantly increased at day 3. Levels of urinary excretion of SBP1, neutrophil gelatinase-associated lipocalin (NGAL), and a tissue inhibitor of metalloproteinase-1 (TIMP-1) were markedly elevated at day 3 and 5 following drug treatment. In the vehicle-treated I/R group, serum levels of BUN and SCr and AST activity were significantly increased compared to sham. Urinary excretion of SBP1 and NGAL rose markedly following I/R. The urinary levels of SBP1, NGAL, TIMP-1, and KIM-1 proteins excreted by AKI patients and normal subjects were compared. Among these proteins, a marked rise in SBP1 was observed in urine of patients with AKI compared to normal subjects. Based upon receiver-operator curves (ROC), SBP1 displayed a higher area under the curve (AUC) scores than levels of SCr, BUN, total protein, and glucose. In particular, SBP1 protein was readily detected in small amounts of urine without purification. Data thus indicate that urinary excretion of SBP1 may be useful as a reliable biomarker for early diagnosis of AKI in patients.</P>

Deposition samples were collected in wet gauge and dry gauge containers at downtown of Iksan city, located southwest of the Korean peninsula, from April 20 to May 1, 2004. The volume of 30-50㎖ deionized water was added for wet gauge before sampling, but dry gauge was installed in the dry state with no deionized water adding. These samples were collected twice a day during daytime and nighttime and were analyzed for anions(Cl^(-), NO^(3-), SO₄^(2-)) and cations (NH₄^(+), Na^(+), K^(+), Mg^(2+), Ca^(2+)) using ion chromatography. Data quality was checked by the data obtained from re-injection of standard solution, Dionex cross check standard solutions, and random several deposition samples, and measured data was estimated to be reliable. Considering the deposition sample volume, the sampling time, the surface area of sampling container, and the ion concentration measured, the deposition amounts were calculated in mg/㎡/day. The sum of ion dry deposition amounts for dry gauge and wet gauge was 9.1±6.7 mg/㎡/day and 26.5±9.1 mg/㎡/day, respectively. A significant increase in deposition amount during rainfall days and Asian yellow dust period was observed for both wet gauge and dry gauge, especially during rainfall days having no difference of deposition amount between in wet gauge and in dry gauge. The mean deposition of all ions measured in this study were higher in wet gauge than in dry gauge because of the surface difference of the sampling container. The mean deposition amount of NH₄^(+), SO₄^(2-), and NO^(3-) in wet gauge were found to be about 27.6 times, 5.5 times, and 3.4 times higher. than that in dry gauge, while the rest of the chemical species were equal or a little higher in wet gauge than in dry gauge. Dominant species in dry gauge were SO₄^(2-) and Ca^(2+), accounting for 14.7% and 47.3% of the total ion dry deposition, whereas those in wet gauge were SO₄^(2-) and NH₄^(+), accounting for 27.7% and 27.1% of the total ion dry deposition, respectively.

목적: 이분절 이하의 퇴행성 요추부 질환에서 후측방 유합술과 후방 추체간 유합술의 임상적, 방사선학적 결과를 분석하여 두 수술을 비교해 보고자 하였다. 대상 및 방법: 이분절 이하의 요추 유합술 및 척추경 나사못 고정술, 감압술을 시행받고 추시관찰이 가능하였던 90명을 대상으로 하였으며 이 중 요추 후측방 유합술을 실시한 환자 45명을 Ⅰ군, 요추체간 유합술을 실시한 환자 45명을 Ⅱ군으로 분류하였다. 결과: 요추 전만도는 Ⅰ군에서 술 전 36.84±8.31°, 술 후 40.58±7.61°, 최종 추시 시 35.73±7.61°이었고, Ⅱ군에서는 31.53±7.09°, 39.11±7.21°, 35.47±7.76°이었다. 골유합은 Ⅰ군에서 45예 중 41예(91.1%), Ⅱ군에서는 45예 중 43예(95.6%)에서 얻었다. 합병증은 Ⅰ군에서 11예(24.4%), Ⅱ군에서는 1예(2.2%)에서 발생하였다. 결론: 이분절 이하의 퇴행성 요추부 질환에서 실시한 후측방 유합술과 후방 추체간 유합술 모두에서 만족할 만한 골유합률과 임상적 결과를 보였고, 두 군 사이의 유의한 차이는 없었다. 요추 전만도와 합병증에서는 후방 추체간 유합술에서 더 좋은 결과를 얻었으나, 임상과 방사선적 결과에 대해서는 좀 더 장기적인 연구가 필요하리라 생각된다. Purpose : This study compared the surgical treatment results between posterior lumbar interbody fusion (PLIF) and posterolateral fusion (PLF) with pedicle screw fixation in degenerative lumbar spinal disorders. Materials and Methods : In 45 cases of PLF (group Ⅰ) and 45 cases of PLIF (group Ⅱ), lumbar lordosis, segmental lordosis, bone union and complications were considered to be an evaluation criterion. Kim's functional evaluation scale was used for the clinical results. Results : The average lumbar lordosis in group I was 36.84±8.31° preoperatively, 40.58±7.61° postoperatively and 35.73±7.61o at the last follow up. On the other hand, the respective changes in the average lumbar lordosis were 31.53±7.09°, 39.11±7.21°, and 35.47±7.76° in group Ⅱ. Definitive solid union was obtained in 41 cases in group Ⅰ (91.1%) and 43 cases in group Ⅱ (95.6%). The rate of complications was 24.4% (11 cases) in group I and 2.2% (6 cases) in group II, and a satisfactory functional outcome were obtained in 43 cases (95.6%) in group Ⅰ and 41 cases (91.1%) in group Ⅱ. Conclusion : Both PLF and PLIF on short segment fusion provided satisfactory bone union and clinical results. In segmental lordosis, there were no significant differences between the two groups. However, PLIF was more effective in preventing lumbar lordosis and complications than PLF. A longer term follow up will be needed to evaluate the adjacent segmental degeneration and maintenance of the sagittal balance.

송명종,김세영,송효남,백남인 경희대학교 생명자원과학연구원 2004 硏究論文集 Vol.23 No.-

쑥갓의 지상부를 MeOH로 추출하고, 추출물을 EtOAc, n-BuOH 및 물로 분배, 추출하였다. n-BuOH분획으로부터 silica gel 및 ODS column chromatography를 반복하여 배당체를 분리하였다. 화합물의 화학구조는, MNR 및 MS 등의 스펙트럼을 해석하여 1-o-β-D-glucopyranosyl-3-hexenol으로 동정하였다. The aerial parts of Garland (Chrysanthemum coronarium L.) were extracted in MeOH and solvent fractionated with EtOAc, n-BuOH and water, successively. n-BuOH fraction gave a glycoside compound through application of silica gel column chromatographies including ODS. The chemical structure of the glycoside was determined by the interpretation of several spectral data, including NMR and MS as O-β-D-glucopyranosyl-3-hexenol (1).
