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...

Patients with adult onset GHD (AO-GHD) manifest features of the metabolic syndrome (MetS) (abdominal obesity, dyslipidemia and insulin resistance), a condition associated with increased risk of diabetes mellitus (DM).We assessed metabolic status before and after 2 years of GH treatment and the occurrence of de novo DM in 712 patients with AO-GHD from HypoCCS drawn from the US (32.2%) and Europe (67.8%). Patients were divided into four BMI categori...

The risk of hypertension is 3-fold increased in women with Turner Syndrome (TS). Coarctation is a known cause of secondary hypertension but for others the aetiology of hypertension is unclear. Studies have demonstrated elevated plasma renin activity (PRA) in girls and young women with TS and hypothesized that the aetiology of hypertension is small vessel renovascular disease. To explore this possibility further blood pressure (BP) and PRA were measured routinely at the Adult T...

Growth hormone (GH) and testosterone are both potent anabolic hormones, but it is not known whether they interact to positively regulate protein metabolism. To address this question, we have carried out two studies, in which we have investigated the impact of GH alone, testosterone alone and combined GH+testosterone, on whole body protein metabolism in hypopituitary men.In the first study, ten subjects received either GH (1.5 units daily) or GH+testosterone (250 milligrams...

AIM: 1) To determine GH dose requirement in GH deficient patients aged over 60 years. METHODS: The study was approved by the local Ethics Committee. Patients were started on Genotropin 0.4 units (0.13 mg)/day after baseline assessment. Serum IGF-I was repeated at 2-weekly intervals. Maintenance GH dose was achieved when serum IGF-1 was between the median and upper end of the age-related range. RESULTS: 16 patients (10 men & 6 women) were recruited. Their median (range) age...

Introduction: While a great degree of focus has recently been placed on identifying novel steroidogenic pathways that are active in cancer development (e.g. Androgen metabolism and Androgen Receptor (AR) Signalling, Glucocorticoid Metabolism and Glucocorticoid receptor (GR) signalling) very few studies have examined these pathways in normal breast samples taken under non-pathological conditions. Furthermore, very few studies have examined the steroid levels in non-pathological...

Background: A variety of insulin analogs have been developed and used for the treatment of diabetes mellitus. We often experience elevated serum insulin levels when insulin analog is used, and thus have difficulty in assessing insulin resistance and secretion using serum insulin results. This study aimed to investigate the differences in serum fasting insulin level and insulin antibodies according to the type of insulin analogs.Method: We conducted a ret...

Cuscuta japonica chois (CJC) has been used traditionally to treat sexual disorder and skin problem such as pimples, freckles and melasma in Korea. The present study aimed to investigate the alleviating effect of CJC extract on surgical injury-induced ischemia in the hind-limb of mice. In this study, Female C57BL/6 mice were ovariectomized and excised the vessels of hind-limb after ligated by surgical silk (6-0). The mice were administered with CJC (150 or 450 mg/kg per day) fo...

Purpose: Papillary thyroid cancer (PTC) has a strong propensity for lymph node metastasis, which is related with local recurrence, and disease-specific survival in the elderly. We evaluated the association between lymph node metastasis and disease multifocality, bilaterality, and other clinicopathological variables to identify risk factors and aid surgical decision-making. The relationship between the number of foci and metastasis to cervical lymph node was also evaluated....

Background: We evaluated the impact of the multifocality on post-lobectomy recurrence in patients with differentiated thyroid cancer (DTC).Methods: We analyzed 1,684 patients with DTC who underwent thyroid lobectomy from 2008 to 2015 using logistic regression models to calculate the relative risk on post-lobectomy recurrence.Results: Tumor diameter increased from 4.9 mm to 8.1 mm and the proportion of extrathyroidal extension (ETE)...
