The daily calcium intake is associated with sarcopenia in older, non-obese koreans: the fourth korea national health an nutrition examination surveys (KNHANES IV) 2009

Park C. , Rhee E. , Oh K. , Park S. , Park S. , Kim S. , Lee W. , Seo M.

Backgroud: The association with daily calcium intake and sarcopenia has not been well established.Objective: The objective was to assess the associate of daily calcium intake and sarcopenia.Methods: We analysed the fourth Korea National Health and Nutrition Examination Survey (KNHANES) in old adult (over 50 years), conducted in 2009. A total of 1964 non-obese (body mass index (BMI) <25 kg/m2) old adults (871 men and ...

A Randomized controlled trial of the effect of internet based mentoring program for type 1 diabetes patients with inadequate glycemic control

Suh S. , Park S. , Cho Y. , Joung J. , Jin S. , Kim S. , Kim H. , Bae J. , Kim S. , Chung J. , Min Y. , Lee M. , Lee M. , Kim K. , Kim J.

Introduction: Widespread availability of internet makes it an attractive communication tool among patients and providers. However, the clinical benefit of telemedical support on diabetes care remains inconclusive. This study is to determine whether an internet based mentoring program can improve glycemic control in type 1 diabetes (T1DM) patients with inadequate glycemic control.Methods: Patients with T1DM on intensive insulin therapy and with HbA1c &#x2...

Diabetes insipidus could be the initial sign of primary hypophysitis

Suh S. , Park S. , Joung J. , Cho Y. , Jin S. , Kim S. , Kim H. , Bae J. , Kim J. , Kim S. , Chung J. , Min Y. , Lee M. , Lee M. , Kim K.

Introduction: The natural history of primary hypophysitis is incompletely understood and best treatment remains controversial.Methods: We performed a retrospective study of 19 patients (mean age of 47 years, fifteen women and four men) who were diagnosed with primary hypophysitis in Samsung Medical Center in Seoul, Korea, from January 2001 to October 2011.Results: Two patients had recent pregnancy and underlying autoimmunity. Most ...

Multiple enhancers regulate expression of the human LHX3 gene in the developing pituitary

Park S. , Mullen R. , Rhodes S.

LHX3 is a LIM homeodomain transcription factor necessary for proper development of the pituitary and central nervous system. Patients with mutations in coding regions of the LHX3 gene have complex syndromes including combined pituitary hormone deficiency and nervous system defects resulting in symptoms such as dwarfism, thyroid insufficiency, infertility, and developmental delay. Although previous studies from our group and others have identified promoter and intronic elements...

LHX3: an insightful model of pituitary hormone deficiency

Rhodes S. , Malik R. , Park S. , Prince K.

Our goal is to better understand the molecular and cellular nature of paediatric combined pituitary hormone deficiency diseases in order to facilitate improved diagnosis, treatment, and family counselling. LIM-homeodomain transcription factors regulate many aspects of development and mutations in the genes that encode these regulatory proteins are associated with several diseases. The LHX3 LIM-homeodomain protein is critical for pituitary gland organogenesis and some nervous s...

A case of pancytopenia with hyperthyroidism

Won K. , Park S. , Moon J. , Yoon J. , Lee H.

Atypical manifestations of hyperthyroidism include hematological, cardiovascular, dermatological manifestation. Especially single lineage abnormalities such as anemia (34%), leukopenia (5.8%), thrombocytopenia (3.3%) are reported, but pancytopenia is a rare presentation of hyperthyroidism. The suspected etiologic mechanisms include ineffective hematopoiesis, reduction in blood cell life span, autoimmune process, toxicity of thyroid hormone.We report a ca...

Predictive ability of prediabetes defined by fasting plasma glucose and HbA1c for progression to diabetes in Koreans

Kim C. , Kim H. , Kim E. , Bae S. , Park J.

Background: The predictive ability of prediabetes defined by HbA1c (5.7–6.4%) or fasting plasma glucose (FPG) criteria (5.6–6.9 mmol/l) for the development of diabetes may differ according to ethnic groups, but only limited longitudinal data are available in Asians. We examined the progression rate to diabetes in Korean adults diagnosed as prediabetes according to these two criteria.Methods: We analyzed data of 9432 Korean adults (age 20–7...

The Association of the severity of nonalcoholic fatty liver disease with development of type 2 diabetes: A 4-year longitudinal study

Choi J. , Bae J. , Park S. , Rhee E. , Park C. , Oh K. , Park S. , Kim S. , Lee W.

Aims: Nonalcoholic fatty liver disease (NAFLD) is reported to contribute to the development of type 2 diabetes, but it is largely unknown whether such a relationship between NAFLD and incident diabetes relates to the severity of NAFLD or it is independent. We aimed to evaluate the association of the severity of NAFLD with development of type 2 diabetes in a retrospective cohort of Korean subjects.Methods: This study included 7,849 individuals without dia...

Syntaxin-3 regulates recruitment and exocytosis of newcomer insulin granules and granule-granule fusion during biphasic glucose-stimulated insulin secretion in pancreatic β-cells

Zhu D. , Koo E. , Kwan E. , Kang Y. , Park S. , Xie H. , Sugita S. , Gaisano H.

Introduction: The molecular basis of exocytosis of secretory insulin-containing granules (SGs) during biphasic glucose-stimulated insulin secretion (GSIS) of pancreatic β-cells remains unclear. Syntaxins (Syns) Syn-1A and Syn-4 are t-SNARE proteins situated on the plasma membrane that have been well studied to mediate insulin exocytosis. However, Syn-3, peculiarly more abundant in insulin SGs, has unclear function in GSIS.Methods/Designs: Confocal m...

The level of Osterix expression in osteoblasts is important to prevent IL6-induced inflammatory-prone state

Baek W. , Kim Y. , Park S. , Kwon T. , Park K. , Kim J.

Osterix (Osx) is an essential transcription factor for osteoblast differentiation and bone formation. Osx null mutants died perinatally with a complete absence of bone formation and Osx conditional knockouts in osteoblasts showed the osteopenic phenotype after birth. Even in Osx heterozygous mice with normal bone morphology, the reduced cortical thickness and osteoblast differentiation were observed by QCT and in vitro cell culture, respectively. This result exhibited t...
