  • Chronic inflammation has been implicated as one of the important etiological factors in insulin resistance and type 2 diabetes mellitus (T2DM). To investigate the role of anti-inflammatory cytokines in the development of T2DM, we conducted a case-control study to assess the association between IL4/IL4R polymorphisms and disease risk. We firstly identified single nucleotide poly-morphisms (SNP) at IL4 and IL4RA loci by sequencing the loci in Korean participants. Case-control studies were conducted by genotyping the SNPs in 474 T2DM cases and 470 non-diabetic controls recruited from community-based cohorts. Replication of the associated signals was performed in 1,216 cases and 1,352 controls. We assessed effect of IL4 -IL4RA interaction on T2DM using logistic regression method. The functional relevance of the SNP associated with disease risk was determined using a reporter expression assay. We identified a strong association between the IL4 promoter variant rs2243250 and T2DM risk (OR=0.77; 95% CI, 0.67~0.88; p=$1.65{\times}10^{-4}$ in the meta-analysis). The reporter gene expression assay demonstrated that the presence of rs2243250 might affect the gene expression level with ~1.5-fold allele difference. Our findings contribute to the identification of IL4 as a T2D susceptibility locus, further supporting the role of anti-inflammatory cytokines in T2DM disease development.

  • Colangiocarcinoma (CCA) is a progressively fatal disease which generally occurs due to malignant transformation of hepatic biliary cholangiocytes. The incidence of CCA has been increasing worldwide and there is an urgent requirement for effective diagnosis and treatment strategies against this devastating disease. Different factors including liver-fluke infestation, viral hepatitis, exogenous nitrosamine-mediated DNA damage, and chronic inflammation have been linked to CCA genesis. However, the risk factors and underlying complex mechanisms leading to development of CCA are not sufficiently understood to devise an effective targeted treatment therapy. In this review, we summarize currently known epidemiological and pathological aspects of the disease and briefly describe various potential biomarkers and experimental anticancer phytochemicals related to CCA research. In addition, we also sum up recent findings that link chronic inflammation of hepatic biliary cholangiocytes with CCA. The collective information concisely presented in this article would provide useful insights into the current understanding of this cancer.

  • Cancer cachexia는 지방조직과 근육계 조직의 손실에 따른 체중의 현격한 감소를 특징으로 하고 있어 궁극적으로는 암 치료제에 대한 반응을 낮출 뿐만 아니라, 삶의 양은 물론 질도 낮추게 되는 시급히 해결되어야 하는 미충족 의료수요 중의 하나이다. 아직까지 임상에서는 수많은 노략에도 불구하고 일부 완화시킬 수 있는 약제가 있기는 하나, 전반적으로 해결이 가능한 약제나 치료 방법이 아직은 없는 실정이다. 그러므로 이를 해결할 수 있는 방법으로 동물모델이 필요한 질환이라 하겠다. 이러한 배경하에 연구자 등은 우선 동물모델을 수립하고 이를 기반으로 적절한 치료제를 개발하기 목적으로 본 연구에서는 C26 대장 선암 세포를 이용한 Cancer cachexia 동물모델을 수립하여 이 모델에서의 변화를 소개함으로써 향후 더 진보된 치료제 개발이나 병태생리를 연구하는데 도움을 주고자 본 연구를 시행하여 다음과 같은 결과를 얻을 수 있었다. C26 adenocarcinoma를 대퇴부 주입 후 시간 경과에 따라 몸무게의 변화가 현저하여 2주 이후에 유의한 몸무게의 감소, 식욕부진, 활동감소가 관찰되었고, 이때의 혈청 Cytokine 및 이를 조절하는 여러가지 전사인자의 변화가 선행되었고, 현저한 근육계의 근감소가 관찰되었으며, 실험동물은 3주에 40%가 사망하는 변화를 보였다. 연구자 등은 본 동물모델은 향후 새로운 치료약제 개발이나 Cancer cachexia 병태생리 연구에 매우 도움이 되는 수립하기 간편하며, 기저 분자생물학적 변화를 관찰할 수 있는 우수한 Cancer cachexia 모델이라 결론지을 수 있었다.

  • Background: Chronic myelocytic leukemia is a disease that threatens both adults and children. Great progress has been achieved in treatment but protein-protein interaction networks underlining chronic myelocytic leukemia are less known. Objective: To develop a protein-protein interaction network for chronic myelocytic leukemia based on gene expression and to predict biological pathways underlying molecular complexes in the network. Materials and Methods: Genes involved in chronic myelocytic leukemia were selected from OMIM database. Literature mining was performed by Agilent Literature Search plugin and a protein-protein interaction network of chronic myelocytic leukemia was established by Cytoscape. The molecular complexes in the network were detected by Clusterviz plugin and pathway enrichment of molecular complexes were performed by DAVID online. Results and Discussion: There are seventy-nine chronic myelocytic leukemia genes in the Mendelian Inheritance In Man Database. The protein-protein interaction network of chronic myelocytic leukemia contained 638 nodes, 1830 edges and perhaps 5 molecular complexes. Among them, complex 1 is involved in pathways that are related to cytokine secretion, cytokine-receptor binding, cytokine receptor signaling, while complex 3 is related to biological behavior of tumors which can provide the bioinformatic foundation for further understanding the mechanisms of chronic myelocytic leukemia.

  • The purpose of this study was to develop the strategy on activation of village by forest healing. Researcher conducted the questionnaire survey for forest healing village development to classify the mountain's characteristics by the three factors(linkage resource, program, facilities). In result, village characteristics were divided into two types: single element outstanding type(resource), complex element outstanding type(resource+program, resource+facilities). The development of forest healing village have to focused on the forest healing service recipient and mountain village characteristics. In conclusion, relationship between forest healing recipient and mountain characteristics was as follows: single type (resource) - public; complex type (resource+program) - chronic disease, social vulnerable people; complex type (resource+facilities) - severe disease. The detailed guideline for forest healing village needs to be established according to the mountain characteristics.

  • The silkworm, Bombyx mori, is prone to infection of various pathogenic organisms. Pebrine, one of the deadliest disease of silkworm caused by highly virulent parasitic microsporidian, Nosema bombycis has been understood since long. Infections of the disease range from chronic to highly virulent and can result in complete loss to the sericulture industry. Several strains and species of microsporidians have since been isolated from the infected silkworms; the disease is becoming increasingly more and more complex. Epizootiology, development of immunodiagnostic kit, use of chemotherapy and thermotherapy techniques has been addressed for identification and control of the disease. A technique of delayed mother moth examination, which plays a decisive role in the detection of the disease and harvestation of stable cocoon crop, has been described. An attempt has been made to review briefly the literature available on various aspects of the pebrine disease in order to develop efficient model(s) for the prevention and control of the disease and to suggest future avenues of investigation in the field of pebrine disease management.

  • Background: Celiac disease (CD) is a chronic autoimmune enteropathy. It results from genetic predisposition and exposure to gluten-containing food. The prevalence and presentation of CD vary among populations. Purpose: This study aimed to describe the prevalence and clinical characteristics of CD in children in Bahrain. Methods: We retrospectively reviewed the medical records of children diagnosed with CD in the pediatric department, Salmaniya Medical Complex, Bahrain, in 1988-2018. Their clinical, biochemical, serological, and histopathological findings were documented. Adherence to the recommended gluten-free diet (GFD) was assessed. Results: Of 86 patients with CD, 67 were included. The CD prevalence was 0.02%. A significant increase in prevalence in the last decade was observed (P<0.0001). Thirty-eight patients (56.7%) were males. The median (interquartile range) age at presentation was 4.45 (1.5-7.3) years. A family history of CD was positive in 13 out of 43 patients (30.2%). Pallor and failure to thrive were the most common presentations. The most frequent associated disease was iron-deficiency anemia in 23 patients (69.7%). Positive serology was found in 32 of 45 patients (71.1%). Marsh-Oberhuber type III was found in 16 of 35 patients (45.7%). Seropositive patients were significantly older (P=0.025) and had more severe duodenal histology (P=0.002). Adherence to GFD was poor in 27 patients (64.3%). Conclusion: This study revealed a significant increase in CD prevalence over the last decade. Atypical presentations were frequent. Most patients had poor adherence to GFD.
