To investigate the effects of short-term administration of DDB(Biphenyl Dimethyl Dicarboxylate) for decreasing elevated serum aminotransferase levels in chronic liver diseases, authors applied 3 capsules of DDB per day at each meal time for 35 patients and compared with 35 patients treated with other conservative management. The following results were obtained. 1. Serum alanine aminotransferase (ALT) levels significantly decreased from 247.1± 180.0 IU/L of pretreatment level to 96.6±126.0 IU/L, 61.1±62.7 IU/L and 38.0±26.8 IU/L after 1, 3 and 6 months of treatment(p<0.05) and effective rates were observed in 60.0%, 71.4% and 88.6% of patients after 1, 3 and 6 months of treatment. 2. Serum aspartate aminotransferase (AST) levels decreased also significantly from 167.8±96.9 IU/L of pretreatment levels to 124.4±155.0 IU/L, 77.9±49.6 IU/L, 60.6± 46.9 IU/L after 1, 3 and 6 months of treatment(p<0.05), but decreasing pattern of serum AST was less significant than that of serum ALT. 3. No significant difference were observed in the serum ALT and AST changes according to the cause and duration of hepatitis. 4. No significant adverse effects were observed in whole patients treated with DDB. It is suggested that small dose administration of DDB is effective for decreasing serum aminotrans ferase levels in chronic liver disease in which other conservative management was not effective.

Purpose: To evaluate the treatment outcome and prognostic factor after postoperative radiotherapy in retroperitoneal sarcoma. Materials and Methods: Forty patients were treated with surgical resection and postoperative radiotherapy for retroperitoneal sarcoma from August 1990 to August 2008. Treatment volume was judged by the location of initial tumor and surgical field, and 45-50 Gy of radiation was basically delivered and additional dose was considered to the high-risk area. Results: The median follow-up period was 41.4 months (range, 3.9 to 140.6 months). The 5-year overall survival (OS) was 51.8% and disease free survival was 31.5%. The 5-year locoregional recurrence free survival was 61.9% and distant metastasis free survival was 50.6%. In univariate analysis, histologic type (p = 0.006) was the strongest prognostic factor for the OS and histologic grade (p = 0.044) or resection margin (p = 0.032) had also effect on the OS. Histologic type (p = 0.004) was unique significant prognostic factor for the actuarial local control. Conclusion: Retroperitoneal sarcoma still remains as a poor prognostic disease despite the combined modality treatment including surgery and postoperative radiotherapy. Selective dose-escalation of radiotherapy or combination of effective chemotherapeutic agent must be considered to improve the treatment result especially for the histopathologic type showing poor prognosis.

Molecularly Engineered Islet Cell Clusters for Diabetes Mellitus Treatment

Yook, Simmyung,Jeong, Jee-Heon,Jung, Yoon Suk,Hong, Sung Woo,Im, Bok Hyeon,Seo, Jin Won,Park, Jun Beom,Lee, Minhyung,Ahn, Cheol-Hee,Lee, Haeshin,Lee, Dong Yun,Byun, Youngro SAGE Publications 2012 CELL TRANSPLANTATION Vol.21 No.8

<P>Pancreatic islet transplantation is a promising method for curing diabetes mellitus. We proposed in this study a molecularly engineered islet cell clusters (ICCs) that could overcome problems posed by islet transplantation circumstances and host's immune reactions. A gene containing highly releasable exendin-4, an insulinotropic protein, was delivered into single islet cells to enhance glucose sensitivity; thereafter, the cells were reaggregated into small size ICCs. Then the surface of ICCs was modified with biocompatible poly(ethylene glycol)-lipid (PEG) (C18) for preventing immune reactions. The regimen of ICCs with low doses of anti-CD154 mAb and tacrolimus could effectively maintain the normal glucose level in diabetic mice. This molecularly engineered PEG-Sp-Ex-4 ICC regimen prevented cell death in transplantation site, partly through improving the regulation of glucose metabolism and by preventing hypoxia- and immune response-induced apoptosis. Application of this remedy is also potentially far-reaching; one would be to help overcome islet supply shortage due to the limited availability of pancreas donors and reduce the immunosuppressant regimens to eliminate their adverse effects.</P>

Particle Deposition Velocity Onto EUVL Masks in Vertical Airflow

Won-Geun Kim,Handol Lee,Se-Jin Yook,Kwan-Soo Lee Institute of Electrical and Electronics Engineers 2014 IEEE transactions on semiconductor manufacturing Vol.27 No.3

<P>Extreme ultraviolet lithography (EUVL) masks are vulnerable to particulate contamination due to the unavailability of pellicles. Particle deposition velocity is used to assess the level of particulate contamination. The particle deposition velocity onto a circular disk or a square flat plate situated perpendicular to the airflow was investigated. The numerical and experimental methods employed in this paper were validated by comparing the numerically simulated mean Sherwood numbers or the experimentally determined particle deposition velocities with the theoretically predicted values for the circular disk, representing a wafer, exposed to vertical airflow. Then, an equation for predicting the particle deposition velocity onto a square flat plate, simulating a EUVL mask, in vertical airflow was suggested by numerically obtaining the mean Sherwood number correlation, and validated through experiments.</P>

( Jin Yoo ),( Eun-ji Oh ),( Ji-su Park ),( Deok-won Kim ),( Jin-hyeok Moon ),( Deok-hyun Kim ),( Daniel Obrist ),( Keun-yook Chung ) 한국공업화학회 2023 공업화학 Vol.34 No.6

The purpose of this study was to determine the inhibitory effect of heavy metals [Cd(II), Ni(II), and Zn(II)] on the growth of Rhodobacter species (Rhodobacter blasticus, Rhodobacter sphaeroides, and Rhodobacter capsulatus) and their potential use for Cd(II), Ni(II), and Zn(II) bioremoval from liquid media. The presence of toxic heavy metals prolonged the lag phase in growth and reduced biomass growth for all three Rhodobacter species at concentrations of Cd, Ni, and Zn above 10 mg/L. However, all three Rhodobacter species also had a relatively high specific growth rate against each toxic heavy metal stress test for concentrations below 20 mg/L and possessed a potential bioaccumulation ability. The removal efficiency by all strains was highest for Cd(II), followed by Ni(II), and lowest for Zn(II), with the removal efficiency of Cd(II) by Rhodobacter species being 66% or more. Among the three strains, R. blasticus showed a higher removal efficiency of Cd(II) and Ni(II) than R. capsulatus and R. sphaeroides. Results also suggest that the bio-removal processes of toxic heavy metal ions by Rhodobacter species involve both bioaccumulation (intracellular uptake) and biosorption (surface binding).

<P><B>Abstract</B></P> <P>The characteristics of fine particle emission from a light-duty diesel vehicle operated on a chassis dynamometer were investigated according to vehicle acceleration and road grade. Particle number (PN) concentration and particle mass (PM) concentration were measured using a Solid Particle Counting System (SPCS), an Engine Exhaust Particle Sizer (EEPS), and a Dekati Low Pressure Impactor (DLPI). In this study, actual mass distribution of particles emitted from the tested diesel vehicle was determined by sampling the particles on 25-mm Teflon-coated filters installed at 13 impactor stages of the DLPI and then compared with the particle mass distribution converted from the particle number distribution measured by the EEPS. In order to evaluate the characteristics of fine particle emission under various conditions of vehicle acceleration and road grade, testing was conducted with or without installing a Diesel Particulate Filter (DPF). In general, PN and PM concentrations increased with both increasing vehicle acceleration and increasing road grade.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Fine particle emission characteristics of a light-duty diesel vehicle were examined. </LI> <LI> A diesel vehicle was operated at various vehicle accelerations and road grades. </LI> <LI> Actual mass distribution of particles emitted from test diesel vehicle was obtained. </LI> <LI> Mass concentration increased as both vehicle acceleration and road grade increased. </LI> </UL> </P>
