PURPOSE: Polycystic ovary syndrome (PCOS) is the most common endocrine disorder that affects women of reproductive age and is characterized by ovulatory dysfunction and/or androgen excess or polycystic ovaries. Women with PCOS present a number of systemic symptoms in addition to those related to the reproductive system. It has been associated with functional derangements in adipose tissue, metabolic syndrome, type 2 diabetes, and an increased risk of cardiovascular disease (CVD). METHODS: A detailed literature search on Pubmed was done for articles about PCOS, adipokines, insulin resistance, and metabolic syndrome...

Obesity in many current pre-clinical animal models of obesity and diabetes is mediated by monogenic mutations; these are rarely associated with the development of human obesity. A new mouse model, the FATZO mouse, has been developed to provide polygenic obesity and a metabolic pattern of hyperglycemia and hyperinsulinemia, that support the presence of insulin resistance similar to metabolic disease in patients with insulin resistance/type 2 diabetes. The FATZO mouse resulted from a cross of C57BL/6J and AKR/J mice followed by selective inbreeding for obesity, increased insulin and hyperglycemia...

The FATZO/Pco mouse is the result of a cross of the C57BL/6J and AKR/J strains. The crossing of these two strains and the selective inbreeding for obesity, insulin resistance and hyperglycemia has resulted in an inbred strain exhibiting obesity in the presumed presence of an intact leptin pathway. Routinely used rodent models for obesity and diabetes research have a monogenic defect in leptin signaling that initiates obesity. Given that obesity and its sequelae in humans are polygenic in nature and not associated with leptin signaling defects, the FATZO mouse may represent a more translatable rodent model for study of obesity and its associated metabolic disturbances...

The purpose of this study was to compare the prevalence of pelvic floor dysfunction (PFD) symptoms in patients with and without polycystic ovary syndrome (PCOS) and among different PCOS phenotypes. This was a case-control study. All participants were assessed using ultrasonography to determine the presence or absence of polycystic ovaries (PCO) and allocated to the case or control group (having healthy females whose husbands were diagnosed with male infertility). The case group was then further subdivided into the three phenotypes according to the presence or absence of menstrual dysfunction (M), hyperandrogenism (HA) and PCO on ultrasonography...

We describe the reactivity of the 2-phosphaethynolate anion (PCO(-)) towards enantiomerically pure α-amino acids (AAs) resulting in the formation of novel salts of phosphinecarboxamides bearing chiral functionalities. These transformations occurred quantitatively with all but one of the amino acids trialled (the basic amino acid arginine was found to be unreactive). The resulting ionic species can be readily protonated to afford N-(phosphanyl)carbonyl-amino acids, a novel group of amino acids bearing primary phosphine functionalities...

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder affecting young women. Even though the definition of PCOS has changed over the years, all diagnostic criteria include two or more of the following: oligomenorrhea/oligoovulation/anovulation, androgen excess and polycystic ovaries (PCO). Traditional method of assessing the ovarian morphology has been transvaginal pelvic ultrasound. Recent studies support that serum anti-Mullerian hormone (AMH) levels correlate with the number of ovarian follicles and cysts...

INTRODUCTION: Neuronal oscillations synchronize processing in the brain over large spatiotemporal scales and thereby facilitate integration of individual functional modules. Up to now, the relation between the phases of neuronal oscillations and behavior or perception has mainly been analyzed in sensor space of multivariate EEG/MEG recordings. However, sensor-space analysis distorts the topographies of the underlying neuronal sources and suffers from low signal-to-noise ratio. Instead, we propose an optimized source reconstruction approach (Phase Coupling Optimization, PCO)...

Oxidative stress has been suggested to play a role in hypertension- and hypertension-induced organ damage. The effect of antihypertensive drug treatments on oxidative stress markers has not been well assessed. Therefore, in this study we investigated the effect of enalapril on oxidative stress markers in hearts of hypertensive rat models such as spontaneously hypertensive rats (SHR) and SHRs administered N-nitro-L-arginine methyl ester (SHR+L-NAME rats). Male rats were divided into four groups: SHRs, SHR+enalapril (SHR-E) rats, SHR+L-NAME rats, SHR+enalapril+L-NAME (SHRE+L-NAME) rats...

Three newly synthesized [Na(+)(221-Kryptofix)] salts containing AsCO(-), PCO(-), and PCS(-) anions were successfully electrosprayed into a vacuum, and these three ECX(-) anions were investigated by negative ion photoelectron spectroscopy (NIPES) along with high-resolution photoelectron imaging spectroscopy. For each ECX(-) anion, a well-resolved NIPE spectrum was obtained, in which every major peak is split into a doublet. The splittings are attributed to spin-orbit coupling (SOC) in the ECX(•) radicals. Vibrational progressions in the NIPE spectra of ECX(-) were assigned to the symmetric and the antisymmetric stretching modes in ECX(•) radicals...

Posterior capsular opacification (PCO) is a major post-operative complication of cataract surgery. Epithelial-mesenchymal transition (EMT) contributes to PCO. We previously indicated that Wnt3a induces the EMT of human lens epithelial cells (LECs) and plays an important role in the development of PCO. The present study aimed to test the potential effect of Dickkopf-1 (Dkk1) on Wnt3a-induced cell migration and the EMT of LECs and to explore possible cellular mechanisms. The secretion of Dkk1 was reduced in the rabbit PCO model, and Dkk1 injected into the eyes post-surgical manipulation prevented PCO formation...

Although BH3 simply coordinates the endocyclic P of (phospholidino)phosphaketene 1(Dipp) , the bulkier B(C6F5)3 gives rise to a zwitterionic diphosphirenium, which is a novel type of 2π-electron aromatic system as shown by the calculated NICS values. While the reaction of 1(Dipp) with Na[PCO(dioxane) x ] is unselective, the same reaction with the sterically bulky (phospholidino)phosphaketene 1(Ar**) [Ar** = 2,6-bis[di(4-tert-butylphenyl)methyl]-4-methylphenyl selectively affords a sodium bridged dimer containing a hitherto unknown λ(3),λ(5),λ(3)-triphosphete core...

Microbial anaerobic conversion of carbon monoxide (CO) and syngas (mainly composed of CO, CO2 and H2) leads to the production of important industrial products, such as acetate and ethanol. The composition of CO- and syngas-converting microbial communities, and the microbial interactions involved are still largely unknown. The main objectives of this study were 1) to understand the effects of CO, CO2 and H2 on the structure and function of a CO-consuming microbial community, and 2) to identify key carboxidotrophs in the mixed culture...
