    Background and Aim: Polycystic ovary syndrome (PCOS) is the most common endocrine disorder among women of reproductive age. The hypothalamus-pituitary-ovary axis dysregulates in PCOS, ultimately leading to hyperandrogenisms. Consequently, it is associated with hirsutism, dyslipidemia, obesity, infertility, menstrual disturbance, and insulin resistance. To our knowledge, there is no detailed investigation of these manifestations. That is why, this study aimed to evaluate manifestations of hyperandrogenism, hirsutism in particular. Methods: This study was performed on 39 women with an initial diagnosis of polycystic ovary syndrome. Rotterdam criteria including Oligo- or anovulation, hyperandrogenism clinical and/or biochemical signs, and ultrasound appearance of polycystic ovaries used as diagnostic criteria. Hirsutism scoring was carried out according to Freeman-Gallwey’s definition of hirsutism. The patients were analyzed for other skin problems including male pattern baldness, acanthosis nigricans, and acne as well as demographic features. Results: Hirsutism was observed in the majority of our patients (91%) ranging from mild to severe. Concerning the distribution of hirsutism on various parts of the body, severe hirsutism was observed more on the groin, abdominal area, and chin respectively. Male pattern baldness, acanthosis nigricans, and acne, and dysregulated menstruation were reported in these patients. Conclusion: This investigation found that skin manifestations, especially hirsutism, are highly frequent in patients with PCOS. *Corresponding Author: Hashem Nayeri; Email: [email protected]; [email protected] Please cite this article as: Masaeli A, Nayeri H, Mirzaei M.

    Background: Polycystic ovarian syndrome (PCOS) is an endocrine disorder that affects women’s fertility and causes alterations such as obesity, insulin resistance, menstrual irregularities, and polycystic ovaries. The results of the studies show that the issue of vitamin D and vitamin D receptor (VDR) is controversial for PCOS susceptibility. Objective: To investigate the association of BsmI polymorphism in the VDR gene with metabolic parameters in obese PCOS women. Materials and Methods: In this case-control study, 38 obese subjects with PCOS and 40 unrelated obese individuals were evaluated to determine the allelic and genotypic frequency of BsmI variant by Polymerase Chain Reaction Restriction Fragment Length Polymorphism method. Body Mass Index, parathyroid hormone, phosphorus, and calcium were evaluated in all participants. Results: BsmI (rs1544410), (A/G) AA, AG, GG, A, and G percentage of genotypic/allelic frequencies were 65.8, 26.3, 7.9, 78.9, and 21.1 in cases and 57.5, 40, 2.5, 77.5, and 22.5 in controls, respectively. Statistical analysis revealed that the differences in genotypic (p = 0.31)/allelic (p = 0.83) frequencies and dominant (p = 0.45)/recessive (p = 0.35) models between the cases and controls were not significant. This study indicates no association between the BsmI genotypes and metabolic parameters. Conclusion: It can be concluded that VDR BsmI (rs1544410) Intron 8 (A > G) was not associated with obesity along with PCOS susceptibility in the studied groups. Key words: Vitamin D receptor, Polycystic ovary syndrome, Genetic association study

    Abstract &nbsp;&nbsp; BACKGROUND: Atherosclerosis is the most important underlying cause of cardiovascular diseases (CVD) which recently has been classified as an inflammatory disorder. Accumulation of large amounts of oxidized LDL in the intima during local inflammation reaction led to increase several factors such as C -reactive protein (CRP). It has also been reported that CRP is able to bind with modified forms of LDL as well as oxidized LDL. These findings suggest possible positive or negative involvement of this protein in atherogenesis. The main objective of the present study was to assess the influence of CRP on LDL oxidation and the possible physical \changes of LDL in the presence of CRP in vitro. &nbsp;&nbsp; METHODS: In this study, the susceptibility of purified LDL to oxidation was assayed by monitoring of formation of conjugated dienes in different physiological concentrations of CRP (0 - 0.5 -2&nbsp; &micro;g/ml) using a shimadzu spectrophotometer. Electrophoresis was used to determine the electrophoretic mobility of LDL in those conditions. &nbsp;&nbsp; RESULTS: CRP significantly reduced the susceptibility of Cu++ -induced LDL oxidation through increasing the lag timeand there was positive relationship between these findings and CRP concentration (P &lt; 0.05). CRP caused a significant reduction in the electrophotretic mobility of LDL compared to native LDL (n-LDL) (P&lt;0.05).&nbsp; &nbsp;&nbsp; CONCLUSION: A considerable reduction was shown in LDL oxidation, in higher concentration of CRP, via an unknown mechanism. The electrophoretic mobility of LDL, in the oxidative condition, decreases in the presence of CRP compared to n-LDL, which can be indicative of the effect of this protein on the physical and chemical properties of LDL. It seems that, other pathway than LDL oxidation is responsible for the effect of CRP on the atherogenesis processes. &nbsp; &nbsp;&nbsp; Keywords: Atherosclerosis, Creactive protein, Low-density lipoprotein, Inflammation. &nbsp;</p
