Objective: Insulin resistance is a core feature of polycystic ovary syndrome (PCOS), thus, it may be the common link between PCOS and type 2 diabetes (T2DM).Although the etiology of PCOS has not been elucidated, a number of studies have suggested that genetic factors may play important roles in its etiology and pathogenesis. If PCOS and T2DM share a common genetic background, genetic variants determining the risk of T2DM may also be associated with PCOS....

The metabolic features of Polycystic ovary syndrome (PCOS) can vary based on the definition used. The aim of this study is to compare the metabolic characteristics of PCOS according to the phenotypes from various diagnostic criteria and help to establish a optimal diagnostic criteria.Subjects with PCOS defined by the NIH criteria (n=494) and the Rotterdam criteria (n=568) and regular cycling non-hirsuite control women (n=1000) were r...

Purpose: For vaginoplasty of Rokitansky syndrome, we use oxidized regenerated cellulose instead of bio-craft that has been used in the past because it requires a less invasive and more physiological surgery. However, the mechanism of epithelialization of this procedure is still not clear. There is a report that differentiation and proliferation of the vaginal epithelium of newborn mice is promoted by administration of basic fibroblast growth factor (bFGF).<p class="abstext...

Both low-frequency electro-acupuncture (EA) and manual acupuncture improve menstrual frequency and decrease circulating androgens in women with polycystic ovary syndrome (PCOS). We sought to determine whether low-frequency EA is more effective than manual stimulation in regulating disturbed estrous cyclicity in rats with PCOS induced by 5α-dihydrotestosterone (DHT). To identify the central mechanisms of the effects of stimulation, we assessed hypothalamic mRNA expression ...

Purpose: The aim of this study in new diagnosed adult women with polycystic ovary syndrome (PCOS) was to evaluate carotid intima media thickness (CIMT) and visceral fat thickness (VFT) measurement by ultrasonography and which method can be used for atherosclerosis risk follow-up.Methods: A case-control study was conducted on 22 PCOS women (18–30 years of age) and 22 controls. BMI was matched volunteer controls. Two different criteria were used to as...

Insulin resistance is one of the common features of the polycystic ovary syndrome (PCOS), and recent studies indicate the possible role of vitamin D in the pathogenesis of insulin resistance and inflammatory response. We aimed to investigate the association between 25-hydroxyvitamin D (25(OH)D) and insulin resistance and inflammatory marker in obese women with PCOS and controls.We recruited 50 obese women with PCOS (age 25±5 years, BMI 27.5±2.3...

Introduction: Pegvisomant is indicated for acromegaly. Doses >20 mg are not commercially available, although daily doses up to 30 mg are approved.Objectives: 1. To estimate the relative bioavailability (relBA) of single-dose pegvisomant s.c. administrations, one injection of 30 mg/ml (1×30) vs two injections of 15 mg/ml (2×15), and 2. To evaluate their pharmacokinetics (PK), safety and tolerability.Methods: This was a...

Introduction: To date, several mutations have been identified as the underlying cause of hypogonadotropic hypogonadism. However, they account for a small minority of cases, suggesting that other genes play a significant role in the pathogenesis. The aim of the present study was to examine the prevalence of KAL1, GnRH1, GnRHR, PROK2 and PROKR2 mutations. Because it has several advantages over traditional screening methods, multiplex ligation dependent probe amplification (MLPA)...

Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders affecting reproductive women. Treatments with Chinese herbal mixtures (HM) and electro-acupuncture (EA) have been proven efficient in clinic. This study evaluated the peripheral and central effects of HM and EA in dihydrotestosterone (DHT)-induced PCOS rats. The female Wistar rats were divided into control (C), control with placebo (CP), DHT-induced PCOS model (PCOS), PCOS model exposed to herbal mi...

Introduction: C-reactive protein (CRP), an acute reactant protein and member of the pentraxins family has a primitive defense function against exogenous organisms. Although its production is predominantly under the control of IL-6, IL-1 and tumor necrotic factor also contribute to hepatic synthesis and CRP secretion. CRP is mainly produced in the liver and possibly other tissues, such as atherosclerotic lesions. C-reactive protein (CRP) is associated with increased risk for ca...
