The Korean-American Church In The 21st Century; A How To Model For Church Growth

Although Korean-Americans have high religious affiliation, they have a low religious commitment. Many Korean-Americans think of the church as a place for relaxation and social connection rather than a place of worship. With the distorted perspective towards the church, the Korean-American churches experience split and division; the church\u27s growth stagnates or declines, and the church is no longer healthy. This project provides suggestions for becoming a healthy church through a case study of the Lord-Jesus Korean Church (LJKC) in Richmond, VA. Based on questionnaires, the project evaluates the effectiveness of the ministries of the LJKC and suggests recommendations for becoming a healthy church

Measuring the Thermal Conductivity of Flowing Liquid Samples Using the Three Omega Method

The thermal conductivity of a liquid is generally measured under conditions that suppress bulk flow in the sample. However, in situ measurement of the thermal conductivity of a flowing liquid would be useful in various scientific and engineering applications. This work demonstrates that a thermal wave technique, such as the three omega method, can effectively measure the thermal conductivity of flowing liquid if the frequency range is adjusted such that the thermal boundary layer is sufficiently thinner than the momentum boundary layer. A new dimensionless number was defined to assess the convection effects, and a criterion for thermal conductivity measurements was obtained for water flowing in a circular tube

Self-assembled nanocomplex between polymerized phenylboronic acid and doxorubicin for efficient tumor-targeted chemotherapy

Since the discovery that nano-scaled particulates can easily be incorporated into tumors via the enhanced permeability and retention (EPR) effect, such nanostructures have been exploited as therapeutic small molecule delivery systems. However, the convoluted synthetic process of conventional nanostructures has impeded their feasibility and reproducibility in clinical applications. Herein, we report an easily prepared formulation of self-assembled nanostructures for systemic delivery of the anti-cancer drug doxorubicin (DOX). Phenylboronic acid (PBA) was grafted onto the polymeric backbone of poly(maleic anhydride). pPBA-DOX nanocomplexes were prepared by simple mixing, on the basis of the strong interaction between the 1,3-diol of DOX and the PBA moiety on pPBA. Three nanocomplexes (1, 2, 4) were designed on the basis of [PBA]:[DOX] molar ratios of 1: 1, 2: 1, and 4: 1, respectively, to investigate the function of the residual PBA moiety as a targeting ligand. An acid-labile drug release profile was observed, owing to the intrinsic properties of the phenylboronic ester. Moreover, the tumor-targeting ability of the nanocomplexes was demonstrated, both in vitro by confocal microscopy and in vivo by fluorescence imaging, to be driven by an inherent property of the residual PBA. Ligand competition assays with free PBA pre-treatment demonstrated the targeting effect of the residual PBA from the nanocomplexes 2 and 4. Finally, the nanocomplexes 2 and 4, compared with the free DOX, exhibited significantly greater anti-cancer effects in vitro and even in vivo. Our pPBA-DOX nanocomplex enables a new paradigm for self-assembled nanostructures with potential biomedical applications.115Ysciescopu

Unilateral Nevoid Telangiectasia Associated with Ipsilateral Melorheostosis

Melorheostosis is a rare disorder characterized by irregular, flowing hyperostosis in long bones, commonly described on radiographs as wax flowing down a candle. In addition to bony sclerosis, cutaneous manifestations overlying the involved bones have been reported including linear scleroderma, neurofibromatosis, and vascular and lymphatic malformations. Unilateral nevoid telangiectasia (UNT) is a rare primarily cutaneous condition characterized by linearly arranged small dilated blood vessels in dermatomal or Blaschkoid patterns on the skin. Here, we present the case of a nine-year-old Korean male with UNT associated with ipsilateral melorheostosis

Cutaneous Metastasis of Choriocarcinoma : A Case Report

Choriocarcinoma is one of the malignant tumors of trophoblastic cells characterized by the secretion of human chorionic gonadotrophin (hCG) (1-3). Cutaneous metastasis is a rare presentation of choriocarcinoma but a poor prognostic sign because it is associated only with widespread disease (3-5). A 52-yr-old female complaining of dyspnea for 2 months, presented with fingertip sized erythematous nodules on the left side of the neck and the right side of the upper back of 1 month duraton. She has suffered from Behçet's disease since 1999. Microscopic examination of a nodule of upper back demonstrated biphasic pattern of cytotrophoblasts and hCG-positive syncytiotrophoblasts, and the typical histologic features of choriocarcinoma. She was referred to the gynecological oncology department. After 17 cycles of combination chemotherapy, the serum hCG level has fallen from 700,000 to under 2.0 mIU/mL and the skin lesions have almost disappeared. However, after 3 months, total abdominal hysterectomy and bilateral salpingo-oophorectomy were performed due to elevated serum hCG level (4,447.7 mIU/mL), and she is scheduled to receive post-operative adjuvant chemotherapy

Two Cases of Acute Leukopenia Induced by Colchicine with Concurrent Immunosuppressants Use in Behçet's Disease

Colchicine-induced leukopenia usually occurrs in intentional or accidental overdoses or inappropriate use in combination with intravenous and oral colchine; however, there have been several reports of hematologic toxicity in short-term and small-dose colchicine medication courses. We present two cases of leukopenia induced by colchicine use concurrent with immunosuppressants in Behçet's disease. We postulate that the mechanism of colchicine-induced leukopenia might be the destruction of circulating leukocytes and an inhibition of leukocyte production by the immediate and direct toxic effect of colchicine on idiosyncrasies unique to each patient. The concurrently administered immunosuppressant might decrease the threshold for hematologic toxicity of colchicine in the leukocytes and their precursor cells

Association of TNFA Promoter Region Haplotype in Behçet's Disease

Although the etiology of Behçet's Disease (BD; MIM 109650) remains to be clearly elucidated, levels of tumor necrosis factor alpha (TNF-α) have been reported to be significantly elevated in BD patients, and TNF-α blockers have been demonstrated to exhibit some degree of therapeutic efficacy for a certain subset of BD sufferers. In this study, we have conducted an analysis of the TNFA haplotypes in the promoter response element that affect the binding affinity of specific transcription factors, in order to characterize their association with the clinical features of BD. Six polymorphisms in the promoter region of TNFA were genotyped in 254 BD patients and 344 control subjects, via the PCR-RFLP technique. TNFA -1031*C, -863*A and -308*G alleles were associated with an increased risk of BD (p=0.030, OR=1.4; p=0.008, OR=1.5; p=0.010, OR=1.8, respectively). The sole TNFA haplotype -1031C-863A-857C-376G-308G-238G, was associated with a 1.6 fold increase in the risk of BD, whereas the TNFA haplotype -1031T-863C-857C-376G-308A-238G was associated with a 0.6 decreased risk of BD. The TNFA -1031*C, -863*A, -857*C and -308*G alleles were significantly associated with BD. The findings of this study, collectively, indicate that TNFA haplotypes in the promoter response elements may exert significant influence on susceptibility to BD

Expression of Pro-inflammatory Protein S100A12 (EN-RAGE) in Behçet's Disease and Its Association with Disease Activity: A Pilot Study

BACKGROUND: S100A12 is a member of the S100 family of calcium-binding proteins and is secreted either in inflamed tissues or in the bloodstream by activated neutrophils. Expression of S100A12 has been reported in various diseases, especially non-infectious inflammatory diseases, such as Kawasaki disease, giant cell arteritis and inflammatory bowel disease. OBJECTIVE: This study was conducted to determine both the tissue expression and the serum levels of S100A12 in Behçet's disease (BD) patients and the correlation of the S100A12 serum level with disease activity of BD. METHODS: We included in this study ten BD patients who fulfilled the criteria for diagnosis, according to the International Study Group for BD. The activity of BD was calculated using the BD Current Activity Form. The serum concentrations of both S100A12 and interleukin-8 were measured by the enzyme-linked immunosorbent assay, before and after treatment. Immunohistochemical studies were also performed to detect S100A12 expression in the skin. RESULTS: The serum S100A12 level was significantly increased in the active BD period (p<0.001), in the inactive BD period (p=0.041) and in patients with active Kawasaki disease (p=0.028), compared with the serum level in the healthy controls. The serum S100A12 level decreased significantly from baseline, compared to post-treatment (p=0.017). The activity score of BD was significantly correlated with the serum level of S100A12 (Spearman's coefficient=0.464, p=0.039). Immunohistochemical studies showed that S100A12 was strongly expressed in the erythema nodosum-like skin lesions of patients. CONCLUSION: S100A12 contributes to the pathogenesis of BD related to neutrophil hyperactivity and reflects the disease activity in BD patientsope
