The chemically induced disturbance during the neurodevelopment stage could cause a serious disease. In vivo study is useful to discriminate against neurotoxic substances but is time-consuming and ethically problematic. So, we have previously established, developmental neurotoxicity test (DNT) in vitro method using Sox1-GFP. In this study we aimed to increase the predictability of discriminant function. The equation was statistically improved using thirty addi...

Butylparaben is an endocrine disrupting chemical (EDC) which is used as antimicrobial preservative in many cosmetic products. EDCs are structurally diverse class of synthetic and natural compounds. EDCs can cause non-communicable diseases such as obesity, type 2 diabetes, and neurodevelopmental disease. Present study investigated that whether exposure to butylparaben during maternal pregnancy could cause the offspring’s neuronal development disorder. In vitro stu...

Previously, we reported that aphidicolin acutely increases nitric oxide (NO) production in bovine aortic endothelial cells (BAECs) by increasing phosphorylation of endothelial nitric oxide synthase at serine 1179 (p-eNOS-Ser1179) and decreasing phosphorylation at serine 116 (p-eNOS-Ser116) without altering eNOS protein expression. Here, we demonstrate that prolonged treatment with aphidicolin (over 24 h) also increased NO production in BAECs. Unlike the a...

Background: The National Health Insurance Service of South Korea is considered to be one of the most effective systems in the world with high accessibility to health care for all Koreans including foreign residents in the country as many as 50 M people. The accumulative information on the behaviors and the statistics of healthcare use based on the National Health Insurance Sharing Service Database has become important for medical research as a nationwide surveillance.<p cl...

Introduction: Subclinical thyroid dysfunction is defined as an abnormal serum thyroid-stimulating hormone (TSH) level and free thyroxine (FT4) and triiodothyronin (T3) levels within their reference ranges. The prevalence of subclinical thyroid dysfunction has increased, especially in women older than 60 years. There is good evidence that subclinical hypothyroidism is associated with progression to overt disease, so screening is recommended for high-risk populations. FREND&#153...

Placenta exchanges vital factors including oxygen, carbon dioxide, cation (copper, iron, calcium) and glucose that are essential to fetal growth. Copper, iron, calcium cation and glucose transfer genes are regulated by reproduction-related hormones, vitamin D and human placental lactogen. These molecules are transferred by specific receptors located on cell membrane or cytoplasm in placenta. These substances disturb action of reproduction-related hormones (ex> estrogen, pr...

Heme oxygenase-1 (HO-1) catalyzes the conversion of heme to carbon monoxide, free iron, and biliverdin, which is then changed into bilirubin. These substances have been recently demonstrated to have antiatherogenic and antioxidative properties. The GT-repeat polymorphism is reported to be an independent risk factor for restenosis after coronary stenting and T (−413). A polymorphism increased the activity of HO-1 promoter, leading to reduce the incidence of ischemic heart...

Abstract: Somatostatin analogs (SSAs) constitute first-line treatment for patients with neuroendocrine tumors. Somatostatin receptors (SSTRs) are the most common therapeutic, radiotherapeutic, and imaging targets of SSAs. Some G-protein-coupled receptors, including SSTRs, regulate their responsiveness to continuous drug exposure with different degrees of receptor internalization. Thus, SSTR internalization seems to play an important role in predicting the response to SSAs in p...

Decamethylcyclopentasiloxane(D5) is one of the most common chemical ingredient for cosmetic products, cleansing agents, hairdye, dry cleaning solvent and personal hygiene supplies. D5 is also known as estrogenic chemical. It can be absorbed through skin, airosol, and even oraly. People are exposed to D5 in daily environment. However, the risk of prenatal exposure to D5 has not yet been fully understood. Recent research shows that imbalance of dam’s estrogen induces brain ...

Eating behavior is determined by both homeostatic and hedonic values. We investigated the association of hedonic value with striatal dopamine transporter (DAT) availability sub-regionally. An intravenous bolus injection of 18F-FP-CIT was administered after the infusion of glucose or placebo, and the emission data were acquired over 90 mins. DAT availability, binding potential (BPND), were measured via the simplified reference tissue method. Subje...
