Hyponeurotrophinemia in Serum of Women with Polycystic Ovary Syndrome as a Low Grade Chronic Inflammation

Introduction: This study aimed to discuss about neuroimmune-pathophysiology of polycystic ovary syndrome (PCOS). Nerve growth factor (NGF) as modulator of neuro-endocrine-immune (NEI) system plays a critical role in tissue survival and homeostasis maintenance. It is a strong marker for sympathetic nerve activity. Women with PCO have enhanced ovarian NGF production. Over the past few decades, PCOS has been discussed as a low grade chronic inflammatory disease. In this study, we investigated the neuromodulator role of serum NGF and inflammatory cytokines (IL-1α, β, 17A and TNF-α) in women with PCOS. Material and Methods: 171 patients were investigated in two groups: study (n = 85 PCO) and control (n = 86). Serum levels of NGF-α and interleukins IL-1α, IL-1β, IL-17A and TNFα were determined in both groups by ELISA kit. Results: Data of this study showed that the level of NGF-α and IL-17A in serum of PCO women were lower than control group (p α, IL-1β were higher than control group in PCO women (p < 0.001). Conclusion: Probably inflammatory background in PCOS is the main cause of increased serum levels of IL-1α, IL-1β. Reduction of IL-17A and NGF in serum of PCO patients might be under the direct influence of the hyperactivity of sympathetic nervous system (SNS).

Synchrony between Ovarian Function &Sleep in Polycystic Ovary Syndrome Patients

Polycystic ovary syndrome (PCOS) is a complex, multifaceted, heterogeneous disorder, affecting 4% to 18% of reproductive-aged women and is associated with reproductive, metabolic and psychological dysfunction. In this study we determined the relationship between the time to sleep and serum levels of neurohormones in polycystic ovary syndrome (PCOS). Totally 77 PCO patients(case group) and 97 non-PCOS infertile women (control subjects) participated in this study between February 2012 and February 2013. A PSQI sleep questionnaire was completed by each patient in both groups. PSQI sleep questionnaire score and serum concentration of adrenaline, noradrenaline, melatonin, β-endorphin, cortisol and progesterone were compared in two groups. The results of the study indicate that serum levels of melatonin and β-endorphin were lower in women with PCOS. Serum level of stress hormones, adrenaline and noradrenaline were significantly correlated with patients’ sleep time in study group. Serum level of adrenaline in control group was significantly lower in women who wake up earlier in the morning. All hormones except for cortisol had no significant correlation with PSQI global score in both groups and also the people who sleep less than 8 hours had lower cortisol level. These data showed that changes in cortisol in PCO women were due to damage of disturbed sleep at night. Our preliminary work provided this study with new insight into the interactions between sleep-wake cycles in PCO women with specific sleep patterns.

Preparation of a novel, efficient, and recyclable magnetic catalyst,γ-Fe2O3@HAp-Ag nanoparticles, and a solvent- and halogen-free protocol for the synthesis of coumarin derivatives

In this protocol, Ag supported on the hydroxyapatite-core–shell magnetic γ-Fe2O3nanoparticles（γFe2O3@HAp-Ag NPs） as a novel, efficient, and magnetically recyclable catalyst is synthesized, and characterized by transmission electron microscopy（TEM）, scanning electron microscopy（SEM）, Fourier transform infrared spectroscopy（FT-IR）, X-ray diffraction（XRD）, and vibrating sample magnetometry（VSM）. The use of the catalyst is described in the synthesis of coumarin derivatives by the Pechmann condensation of various phenols with β-ketoesters under solvent- and halogen-free conditions at 80℃.This novel and inexpensive method offers advantages, such as recyclability simple experimental protocol, short reaction time, minimal work-up procedure, and excellent yields of products, together with desirable, eco-friendly, green aspects by avoiding toxic elements and solvents, and ease of recovery from the reaction mixture using an external magnet.
