These results revealed that fasting and 2-hr plasma glucose levels, as well as the proinsulin/insulin ratio before transplantation, are both possible indicators of beta-cell dysfunction and may be predictors for the development of PTDM. Furthermore, beta-cell dysfunction, rather than insulin resistance, was proven to be the main factor for the pathogenesis of PTDM.

OBJECTIVE: Phyto-oestrogens are plant compounds with both oestrogenic and anti-oestrogenic properties. However, it is not known whether natural phyto-oestrogens are beneficial or harmful in human osteoporosis. This study was performed to investigate the relationships between urinary phyto-oestrogens and bone mineral density (BMD) in Korean postmenopausal women. DESIGN: The subjects were classified into osteoporotic, osteopenic and normal groups according to their BMD as defined by WHO criteria.

Hippo signaling acts as a tumor suppressor pathway by inhibiting the proliferation of adult stem cells and progenitor cells in various organs. Liver-specific deletion of Hippo pathway components in mice induces liver cancer development through activation of the transcriptional coactivators, YAP and TAZ, which exhibit nuclear enrichment and are activated in numerous types of cancer. The upstream-most regulators of Warts, the Drosophila ortholog of mammalian LATS1/2, are Kibra, Expanded, and Merli

Obesity is associated with numerous metabolic comorbidities. Weight loss is an effective measure for alleviating many of these metabolic abnormalities. However, considering the limited success of most medical weight-management approaches in producing a sustained weight loss, approaches that improve obesity-related metabolic abnormalities independent of weight loss would be extremely attractive and of practical benefit. Metabolically healthy obesity supports the notion that a better metabolic pro

AIMS: To investigate the association of clinical and immunological markers with diabetes classification in newly diagnosed young diabetic patients at disease onset. METHODS: Eighty-two diabetic patients recruited within 1 year of onset (mean age 23.0 +/- 7.1, M:F = 46:36) were divided into three groups, namely: a low fasting C-peptide (FC) level at baseline group (the low FC group (n = 14, FC < 0.18 nmol/l)), an intermediate FC group (n = 29, 0.18 nmol/l < or = FC < 0.37 nmol/l), and a high FC g

Glioblastoma multiforme (GBM) is the most aggressive type of brain tumor, characterized by its heterogeneity in cellular components, including reactive astrocytes and microglia. Since neuroimmune responses like astrogliosis and microgliosis gain recognition as vital factors in brain tumor progression, there is a growing need for clinically relevant models that assess the interactions between astrocytes, microglia, and GBM. Here, a NEuroimmune-Oncology Microphysiological Analysis Platform (NEO-MA

Purpose: Pembrolizumab is currently used to treat advanced triple-negative breast cancer (TNBC) and high-risk early TNBC with neoadjuvant chemotherapy (NAC). The tumor-infiltrating lymphocyte (TIL) level and programmed cell death ligand 1 (PD L1) status are predictors of response to NAC and immune checkpoint inhibitor treatment. We aimed to investigate whether the PD-L1 status in core needle biopsies (CNBs) could represent the whole tumor in TNBC. Materials and Methods: A total of 49 patients di

Background: The Bethesda System for Reporting Thyroid Cytopathology (BSRTC) uses six diagnostic categories to standardize communication of thyroid fine-needle aspiration (FNA) interpretations between clinicians and cytopathologists. Since several studies have questioned the diagnostic accuracy of this system, we examined its accuracy in our hospital. Methods: We calculated the incidences and malignancy rates of each diagnostic category in the BSRTC for 1,730 FNAs that were interpreted by four cy

Purpose Forkhead box C1 (FOXC1) is critical for maintaining bone marrow microenvironments during hematopoiesis, but its role in hematological malignancies remains obscure. Here, we investigated whether FOXC1 regulates tumor dormancy and activation in the microenvironments of T and natural killer (NK) cell lymphomas. Materials and Methods One hundred and twenty cases of T and NK cell lymphomas were included; the immunohistochemical expression of FOXC1 was investigated in stromal cells, and number

Background/Aims: As compared with the general population, patients with schizophrenia have a higher risk of obesity and glucose metabolism impairment. Moreover, some antipsychotic drugs add to this risk owing to side effects such as weight gain. However, few reports exist regarding the pathophysiology of insulin resistance in drug-naive or drug-free schizophrenic patients. Therefore, the aim of the present study was to investigate the factors that contribute to insulin resistance in antipsychoti

Hepatocellular carcinoma (HCC) has heterogeneous molecular and pathological features and biological behavior. Large-scale genetic studies of HCC were accumulated, and a pathological-molecular classification of HCC was proposed. Approximately 35% of HCCs can be classified into distinct histopathological subtypes according to their molecular characteristics. Among recently identified subtypes, macrotrabecular massive HCC, neutrophil-rich HCC, vessels encapsulating tumor clusters HCC, and progenito

649 BACKGROUND: Post-transplant diabetes (PTDM) is a common complication in renal transplant recipients and the prevalence is 3 times greater than that of normal population in Korea. Understanding the nature of PTDM is important for an adequate management of diabetes, but the exact mechanism of PTDM is not clear, yet. METHOD: We performed an oral glucose tolerance test (OGTT) and insulin response to OGTT pre- and post-transplant, and measured basal insulin, proinsulin levels post-transplant in 5

본 연구는 이전에 타당화 된 반사회적 성격 평가 척도 (Antisocial Process Screening Device; 이하 APSD)를 재타당 화 하는 것을 목적으로 한다. 국내의 만 15세에서 18세 일반 청 소년 400명(남,여 각각 200명)을 대상으로 진행하였다. 탐색적 요인분석(EFA)을 실시하여 APSD의 요인구조를 알아보았다. 그 후 차별기능문항(Differential Item Function; 이하 DIF) 분석을 통하여 성별 간 다르게 기능하는 문항을 알아보고자 하였다. 마 지막으로 문항반응이론(Item Response Theory; 이하 IRT) 분 석을 통하여 APSD의 요인 별 문항 기능을 점검하고자 하였다. 그 결과 APSD는 4요인 구조로 나타났다. 요인 1은 ‘조종 (Ma)’ 요인, 요인 2는 ‘반사회성(Ant)’ 요인, 요인 3은 ‘자기애 (Nar)’ 요인, 요인 4는 ‘무기력(Leth)’ 요인으로 구성되었다. 총 20문항 중 세 문항(3번, 18번,
