Alarin: A new predictive marker in infertile women with polycystic ovary syndrome: A case-control study.

AIM: There is scant evidence concerning the relationship of alarin concentrations for polycystic ovary syndrome (PCOS) status in the existing literature. Therefore, we aimed to reveal the relationship about predictive value of serum alarin concentrations for PCOS risk in infertile women. METHODS: This prospective case-control study included a total of 151 infertile women who met eligibility criteria of the study. Infertile women diagnosed with PCOS formed the study group (n = 80). Women with diagnoses of unexplained infertility constituted the control group (n = 71). The biochemical analyses of serum concentrations of lipid profiles, estradiol (E2), follicle-stimulating hormone (FSH), luteinizing hormone (LH), anti-Mullerian hormone (AMH) and alarin were performed. RESULTS: There were no differences for the study parameters, including age, body mass index, fasting glucose, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, total triglyceride, E2, and FSH levels in either group. Serum LH, AMH, alarin concentrations, and antral follicle counts had higher values in the PCOS group compared with the controls. Correlation analysis revealed that serum alarin levels were significantly positively correlated with LH and AMH levels, only in the PCOS group. Multivariate binary logistic regression analysis demonstrated that infertile women with high alarin concentrations were significantly more likely to develop PCOS (OR = 1.77, 95% CI = 0.095-0.332, p < 0.001). CONCLUSION: Higher serum concentrations of alarin and a positive correlation with serum LH levels were found in infertile women with PCOS. This evidence supported that high alarin concentrations might play a role in the development of PCOS.

The effects of galangin in prepulse inhibition test and experimental schizophrenia models.

OBJECTIVE: Acetylcholinesterase inhibitors are the focus of interest in the management of schizophrenia. We aimed to investigate the effects of acute galangin administration, a flavonoid compound with acetylcholinesterase inhibiting activity, on schizophrenia-associated cognitive deficits in rats and schizophrenia models in mice. METHODS: Apomorphine-induced prepulse inhibition (PPI) disruption for cognitive functions, nicotinic, muscarinic, and serotonergic mechanism involvement, and brain acetylcholine levels were investigated in Wistar rats. Apomorphine-induced climbing, MK-801-induced hyperlocomotion, and catalepsy tests were used as schizophrenia models in Swiss albino mice. The effects of galangin were compared with acetylcholinesterase inhibitor donepezil, and typical and atypical antipsychotics haloperidol and olanzapine, respectively. RESULTS: Galangin (50,100 mg/kg) enhanced apomorphine-induced PPI disruption similar to donepezil, haloperidol, and olanzapine (p < 0.05). This effect was not altered in the combination of galangin with the nicotinic receptor antagonist mecamylamine (1 mg/kg), the muscarinic receptor antagonist scopolamine (0.05 mg/kg), or the serotonin-1A receptor antagonist WAY-100635 (1 mg/kg) (p > 0.05). Galangin (50,100 mg/kg) alone increased brain acetylcholine concentrations (p < 0.05), but not in apomorphine-injected rats (p > 0.05). Galangin (50 mg/kg) decreased apomorphine-induced climbing and MK-801-induced hyperlocomotion similar to haloperidol and olanzapine (p < 0.05), but did not induce catalepsy, unlike them. CONCLUSION: We suggest that galangin may help enhance schizophrenia-associated cognitive deficits, and nicotinic, muscarinic cholinergic, and serotonin-1A receptors are not involved in this effect. Galangin also exerted an antipsychotic-like effect without inducing catalepsy and may be considered as an advantageous antipsychotic agent.

The circulating alarin level was elevated in infertile women with poor ovarian reserve.

OBJECTIVE: We aimed to reveal the association of serum alarin level with POR status of the infertile women in the present study. METHODS: The eligibility criteria for this prospective cross-sectional study included a total of 92 infertile women attending the Hitit University Hospital, and all participant women were categorized into two main groups of ovarian reserve: (i) Poor ovarian reserve (POR) group (n = 40) based on ESHRE consensus and (ii) Control group (NOR) (n = 52). RESULTS: The mean adjusted-ages and BMI values of the NOR and POR groups were statistically comparable (p = .057 and p = .600, respectively). The mean E2, FSH, and LH levels were elevated in the POR group (p < .001, for all). The mean AFC and AMH concentration were significantly reduced in the POR group (p < .001, for both). In addition, there was a significant increase in the serum alarin level in the POR group (p < .001). Pearson's analysis revealed that the mean BMI value of the POR group had a weak and negative correlation (r = 0.318, p = .046). Also, there was no correlation between serum alarin with E2 and FSH levels in both study groups. A weak and positive correlation was found between serum alarin and LH concentration only in the POR group (r = 0.318, p = .045). The mean AMH and AFC values were not significantly correlated with serum alarin levels. CONCLUSION: The circulating alarin level was significantly elevated in infertile women with POR patterns. In addition, the alarin level was significantly correlated with the serum LH concentration in the POR pattern.

Protective effects of anandamide against cisplatin-induced peripheral neuropathy in rats

Background/aim: Cisplatin (CIS) is an effective antineoplastic agent used in the treatment of several cancer types. Peripheral neuropathy is a major dose-limiting side-effect in CIS therapy. Cannabinoids may alleviate this painful side effect. This study investigated the analgesic effects of anandamide (AN) on CIS-induced peripheral neuropathy, in vitro effects of AN in CIS neurotoxicity, and the contribution of nitric oxide (NO) in this effect. Materials and methods: This is an experimental animal study. Primary dorsal root ganglion (DRG) cultures were prepared from one-day-old rats for in vitro investigations. DRG cells were incubated with CIS (100­300 M), and AN (10, 50, 100, and 500 µM) was administered with the submaximal concentration of CIS. Female Sprague Dawley rats were divided into control, CIS, CIS+AN, CIS+AN+L-NG-nitro arginine methyl ester (LNAME). CIS was administered 3 mg/kg i.p once weekly for 5 weeks. AN (1 mg/kg i.p) or in combination with 10 mg/kg i.p LNAME was administrated 30 min before CIS injection. Mechanical allodynia, thermal hyperalgesia, and tail clip tests were performed. After intracardiac perfusion, sciatic nerves (SN), and DRGs were isolated and semi-thin sections were stained with toluidine blue and investigated histologically. SPSS v. 21.0 and Sigma STAT 3.5 were used for statistical analysis. One/two way ANOVA, Kruskal­Wallis, and Wilcoxon signed ranks tests were used. A p-value of 0.05 was accepted as significant. Results: CIS caused significant mechanical allodynia. AN and AN+LNAME significantly increased hind paw withdrawal latency in mechanical allodynia test. The degenerated axons significantly increased in CIS group, while decreased in AN group. The frequency of larger neurons seemed to be higher in CIS+AN group. Conclusion: AN may be a therapeutic alternative for the treatment of CIS-induced peripheral neuropathy. However, its central adverse effects must be considered.

Compulsory Vaccination and the Turkish Constitutional Court.

As vaccine hesitancy is on the rise around the world, apex courts in some countries have confronted the difficult task of striking a fair balance between individual rights and the common good. Against this background, the article discusses the compulsory vaccination cases heard by the Turkish Constitutional Court (TCC). The TCC's case law illustrates that any interference with bodily integrity must first comply with the principle of lawfulness and its rulings addressed an important shortage of the current Turkish compulsory childhood vaccination policy. The article suggests that the principle of lawfulness in compulsory vaccination cases should not be taken lightly, even if it serves compelling public interests.

Effect of CYP3A5 and ABCB1 Gene Polymorphisms on Tacrolimus Blood Concentration in Renal Transplant Recipients.

BACKGROUND: Tacrolimus (Tac) is a calcineurin inhibitor (CNI). Its therapeutic range is narrow and pharmacokinetic properties vary among patients. CYP3A5 and MDR1 single-nucleotide polymorphisms (SNPs) are the most effective polymorphisms that play an significant role in the pharmacokinetics of Tac. METHODS: We investigated the influence of CYP3A5 (A6986G) and MDR1 (C3435T) gene polymorphisms on Tac trough concentration (C0), dose requirements (mg/kg), and dose-adjusted concentrations (ng/mL per mg/kg/d). CYP3A5 [*1/*1 (expresser), *1/*3 (expresser); *3/*3 (non-expresser)] and MDR1 (CC, CT, TT) gene polymorphisms were determined by allele-specific polymerase chain reaction in 67 adult Turkish renal transplant patients. The Tac dose (mg/kg/d) and C0 of each patient was acquired from the patient's file and dose-adjusted concentrations (ng/mL per mg/kg/d) were calculated at the 1st, 3rd, 6th, and 12th months after transplantation. The correlated serum hematocrit, platelet, urea, creatinine, and albumin were also determined. RESULTS: The CYP3A5*1/*3 and CYP3A5*3/*3 allelic frequencies were 5.97% and 94.03%, respectively. There were no patients with the CYP3A5*1/*1 genotype. Tac dose was significantly lower in *3/*3 genotype than in *1/*1 genotype (3rd and 6th months: p ≤ 0.001; 12th month: p ≤ 0.05). Dose-adjusted Tac concentration was statistically higher in the *3/*3 genotype than in *1/*1 genotype at the 3rd and 6th months (p ≤ 0.05). The allelic frequencies of MDR1 CC, CT, and TT were 26.87%, 49.25%, and 23.88%, respectively. No statistically significant differences were detected between MDR1 genotypes and in all analyzed laboratory parameters. CONCLUSIONS: CYP3A5 but not MDR1 genetic polymorphisms affected the Tac pharmacokinetics and dose requirements in renal transplant recipients. Pharmacogenetic methods can be used for selecting the initial dose to individualize immunosuppressive therapy.

Spontaneous triplet pregnancy and trap sequence, case report.

BACKGROUND: Spontaneous multiple pregnancies are rare, and the incidence of spontaneous triplet pregnancy is about 1/4000. TRAP (Twin Reversed Arterial Perfusion) sequence has acardiac foetus with non-viable multiple anomalies, and there is a pump foetus which feeds this foetus with placental anastomoses. TRAP sequence phenomena is quite rare in triplet pregnancies. CASE PRESENTATION: The patient who applied to our clinic was 30 years old. Monochorionic diamniotic triplet pregnancy was detected by ultrasonographic examination. First amniotic sac had one foetus (Foetus A). Ultrasonographic evaluation of Foetus A revealed gestational age of 31 weeks, adequate amniotic fluid and no fetal structural anomalies. The second amniotic sac contained 2 foetuses and polyhydromnios. Ultrasonic measurements of Foetus B were consistent with 32 weeks gestational age. Color flow doppler indicated Foetus B was the pump foetus. Foetus C was an acardiac foetus with no sonographic visualization of cranium, thoracic organs or extremities, but abdominal circumference consistent with 28 weeks. Pregnancy was followed conservatively and evaluated regularly by ultrasonography twice a week. When prolonged bradycardia was detected in fetus B at 35 4/7 weeks, emergency cesarean section was performed. Two healthy fetuses weighing 2 kg were delivered each with an 8/10 APGAR score (Appearance, Pulse, Eye Insertion, Activity, Respiration). CONCLUSION: This case was managed without any invasive procedures and demonstrates that treatment of TRAP sequence cases can be individualized considering clinical conditions, the size of the acardia twin and extent of placental venous anastomoses.

A Case-Control Study on the Oxidative Status in Women with Polycystic Ovary Syndrome Treated with Clomiphene Citrate.

BACKGROUND Polycystic ovary syndrome (PCOS) is associated with infertility or subfertility due to impaired ovulation. Clomiphene citrate is a first-line treatment option for the induction of ovulation in women with PCOS. The study aimed to compare markers of oxidative stress or the total oxidative status (TOS), total antioxidant status (TAS), and levels of paraoxonase-1 (PON-1) before and after day 21 of the menstrual cycle in women with PCOS treated with clomiphene citrate to induce ovulation. MATERIAL AND METHODS The study included 75 women who were divided into a control group (n=25) that included healthy untreated women, untreated women with PCOS (n=24) who had spontaneous ovulation, and women with PCOS who were treated with clomiphene citrate for subfertility or infertility (n=26) (the PCOS-CC group). The study group was treated for five days with clomiphene citrate (50 mg/day). Peripheral venous blood was sampled on day 3 and day 21 of the menstrual cycle from women in all three groups, and TAS, TOS, and PON-1 levels were measured. RESULTS In all three groups, TAS and PON levels were significantly reduced and TOS values were significantly increased on day 21 of the menstrual cycle. Comparison of TAS, TOS, and PON-1 levels between the three study groups on day 3 and day 21 of the menstrual cycle showed no significant difference (p=0.600, p=0.223, p=0.956, respectively). CONCLUSIONS This study showed that spontaneous ovulation occurs in association with an oxidative state in healthy women and women with PCOS, and women with PCOS following treatment with clomiphene citrate.

Can the negative effects of ketamine abuse on female genital organs be prevented by nimesulide? An experimental study.

The objective of this study is to investigate the effects of nimesulide on ketamine-induced ovarian and uterine toxicity by biochemical and histopathological examinations. Ketamine is an anesthetic agent whose use leads to overproduction of catecholamines. Nimesulide is a cyclooxygenase-2 inhibitor, which has also been reported to exert a significant antioxidant effect. Wistar albino female rats were randomly divided into three groups as follows: ketamine group (60 mg/kg), ketamine (60 mg/kg) + nimesulide (50 mg/kg) group, and a healthy control group. Then, the biochemical levels and histopathological findings in the ovaries and uteri of the rats were examined for malondialdehyde, myeloperoxidase, total glutathione and superoxide dismutase. The study demonstrated that, in the uterine and ovarian tissues of rats that have been administered ketamine, there was a decrease in the levels of total glutathione and superoxide dismutase, while malondialdehyde and myeloperoxidase was increased: however it was observed that these ratios were reversed in the ketamine+nimesulide group. It was also proved that the negative effects of ketamine can be corrected with nimesulide when the myometrial and endometrial thicknesses are compared. Antioxidants such as nimesulide may protect against the damage caused by ketamine to the genital organs in young women.

The relationship of hyperemesis gravidarum with sleep disorders, anxiety and depression.

The purpose of this study was to compare patients who were diagnosed with hyperemesis gravidarum (HG) with the control group by identifying anxiety, depression, sleep disorder levels and the relationship between them. This study involved 98 first-trimester pregnant women (46 HG patients and 52 control group patients) who applied to the Hitit University Medicine Faculty Obstetrics and Gynecology clinic. Statistically significant differences were found between HG patients and the control group according to the Beck Anxiety Inventory (BAI) and Beck Depression Inventory (BDI) scores (p < .001 and p < .001, respectively). In addition, a significant relationship was found between the classification performed according to the Pittsburgh Sleep Quality Index (PSQI) scores and HG (p < .001). According to PSQI scores, while 60.9% of HG patients had severe sleep disorders, 7.7% of the patients in the control group had severe sleep disorders. These findings clearly show that the PSQI scores increased as a result of nausea and vomiting. Impact statement What is already known on this subject? The aetiology of hyperemesis gravidarum has not yet been clarified. There are some studies that relate pregnancy to anxiety and depression. What the results of this study add? In our study, we aimed to evaluate first-trimester vomiting with psychological disorders. What the implications are of these findings for clinical practice and/or further research? There was a statistically significant relationship between PSQI scores and BAI and BDI scores in the HG group. However, this relationship was not detected in the control group. Also, PSQI scores increased as a result of nausea and vomiting in HG cases.

The Effect of Religious Belief on the Attitudes of Pregnant's Toward the Fetal Health.

The purpose of this study is to identify the effect of religious beliefs on the attitudes of pregnant women toward the health of the fetus. Pregnancy, one of the important periods of life, is a special period in terms of affecting both the mother's and the baby's health. Health beliefs and attitudes are the factors that have effects on mother-baby death rates (mortality)-which is one of the most important criteria showing health level of societies. However, the literature has limited number of studies on this issue. Volunteer participants who applied to the Gynecology and Obstetrics Polyclinic were administered a questionnaire in order to identify the frequency of performing worship practices. Women's beliefs about their roles in determining their fetus's health were measured using Fetal Health Locus of Control (FHLC) scale. FHCL scale is composed of 3 sub-scales which include Internality Locus of Control (FHLC-I), Chance Locus of Control (FHLC-C), and Powerful Others Locus of Control (FHLC-P). Non-normally distributed scale scores were analyzed with Mann-Whitney U test for two independent groups and Kruskal-Wallis test for three independent groups. The scores obtained from all the sub-scales of the FHLC scale according to the praying groups were statistically significant (p = 0.008, p < 0.001, p < 0.001, respectively). The sub-scale scores were not statistically significant according to the tendency of giving alms (p = 0.269, p = 0.695, p = 0.079, respectively). The FHLC-I and FHLC-P scores did not indicate differences according to the tendency of going to pilgrimage (p = 0.914, p = 0.578), but FHLC-C scores were significantly higher in those who tended to go to pilgrimage (p = 0.004). There was a significant relationship between the tendency of performing prayer and going to pilgrimage and attitudes toward performing double-triple tests and oral glucose tolerance test (p = 0.002, p = 0.035, respectively). Religious beliefs were influential on the attitudes of pregnant women toward the health of the fetal. Gynecologists should consider patients' religious belief sensitivity while recommending them screening tests or planning their medication.

Human Papilloma Viruses and Their Genotype Distribution in Women with High Socioeconomic Status in Central Anatolia, Turkey: A Pilot Study.

BACKGROUND In the present study we retrospectively evaluated the results of outpatients who had an HPV analysis, and present objective evidence for the administration of preventive inoculation in our area. MATERIAL AND METHODS We retrospectively reviewed 532 outpatients who visited a single center between 2012 and 2016 and had an HPV infection analysis. The criteria for inclusion of patients with unhealthy cervix in the study were: erosion, chronic cervicitis, healed lacerations, hypertrophied cervix, and abnormal discharges from the cervix. RESULTS We found that 122 out of 532 patients were infected with HPV, and the rate of multiple infections was 59.0% (72/122). HR-HPV (group 1 carcinogens HPV-16 (18.9%, 23/122), HPV-18 (13.1%, 16/122), HPV- 31 (4.9%, 6/122), HPV-33 (3.3%, 4/122), HPV-35 (7.4.9%/122), HPV-39 (5.7%, 7/122), HPV-45 (5.7%, 7/122), HPV-51 (11.5%, 15/122); Group 3 LR-HPV; HPV-6 (31.1%, 38/122), HPV-11 (26.2%, 32/122), HPV-42 (9.0%, 11/122) and HPV-43 (4.9%, 6/122). In terms of linear-by-linear association test, no significant statistical difference was identified between years. The P value for HPV infection rate on year basis was P>0.05. CONCLUSIONS In this hospital-based retrospective analysis, HPV types were found to be similar to HPV types reported in developed countries. We firmly suggest that patients should be informed about the risk of HPV infection at early ages.

Thrombophilia and Recurrent Pregnancy Loss: The Enigma Continues.

BACKGROUND Thrombophilic gene polymorphism is known to be a risk factor for recurrent pregnancy loss (RPL), but few studies have confirmed a possible role of thrombophilic genes polymorphism in RPL risk. This study was conducted to understand the relationship of the mutations of some thrombophilia-associated gene polymorphism (heterozygous/homozygous) with RPL. We compared patients with 2 abortions to patients with 3 or more abortions among Turkish women. MATERIAL AND METHODS In this study, patients previously diagnosed with habitual abortus at Obstetrics and Gynecology outpatient clinics in Turkey between 2012 and 2016 were included. In their peripheral blood, we detected factor V Leiden H1299R, prothrombin G20210A, MTHFR C677T, MTHFR A1298C, PAI-1 4G/5G, and PAI-1 4G/4G gene mutations. RESULTS In this study, we have observed statistically meaningful data (P<0.01) related to the relationship between RPL and thrombophilia-associated gene polymorphisms such as heterozygous factor V Leiden H1299R, heterozygous prothrombin G20210A, PAI-1 4G/5G, and PAI-1 4G/4G. CONCLUSIONS We found that diagnosis of thrombophilic genes polymorphism is useful to determine the causes of RPL, recognizing that this multifactorial disease can also be influenced by various acquired factors, including reproduction-associated risk factors and prolonged immobilization.

Serum orexin-A (OXA) level decreases in polycystic ovarian syndrome.

AIM: In the current study, we aimed to investigate whether serum orexin-A (OXA) levels are different in polycystic ovary syndrome (PCOS) subjects. MATERIALS AND METHODS: Thirty-six women with PCOS and 40 healthy, age and body mass index-matched controls were included in the prospective cross-sectional study. All subjects underwent venous blood draws during the early follicular phase after overnight fasting. Serum OXA levels were measured with an enzyme immunoassay (EIA). The relationships between the serum OXA levels and the anthropometric and metabolic parameters were also assessed. RESULTS: The serum OXA levels were lower in the women with PCOS compared to the control group. The serum OXA levels were correlated negatively with systolic blood pressure, the Ferriman-Gallway score and LH and free testosterone levels. CONCLUSION: Our results indicate that serum OXA levels decrease in the serum of women with PCOS.

Antinociceptive effects of gabapentin & its mechanism of action in experimental animal studies.

BACKGROUND & OBJECTIVES: Several studies have shown the possible analgesic effects of gabapentin, widely used as an antiepileptic. Thus, clinical studies have been carried out especially for neuropathic syndroms. This study was undertaken to investigate experimentally whether gabapentin has analgesic effects in mice and rats. METHODS: The mice were divided into 10 groups (n=7) with various treatments to assess central and peripheral antinociceptive activity of gabapentin. Hot plate, tail clip and tail flick tests were applied for the investigation of central antinociceptive activity and the writhing test was applied for the investigation of peripheral antinociceptive activity. In addition, we also evaluated the levels of PGE 2 and nNOS on perfused hippocampus slices of rats. RESULTS: Gabapentin showed a peripheral antinociceptive effect at all doses and a central antinociceptive effect at 30mg/kg dose. While the L-NAME and cyproheptadine changed the central and peripheral effects of gabapentin, naloxone did not change these effects. In vitro studies showed that gabapentin significantly increased nNOS level. PGE 2 and nNOS were found to have an important role in the antinociceptive effects of gabapentin at all doses and its combinations with L-NAME, cyproheptadine, indomethacine, and naloxone. As expected, PGE 2 levels decreased in all groups, while nNOS levels increased, which is believed to be an adaptation mechanism. INTERPRETATION & CONCLUSIONS: Our findings indicate that arachidonate, nitrergic and serotonergic systems play an important role in the antinociceptive activity of gabapentin except for the opioidergic system. Additionally, this effect occured centrally and peripherally. These effects were also mediated by nNOS and PGE2.

Copeptin: A potential marker for the prediction of poor ovarian reserve in the infertile women.

Objective: There is actually no evidence regarding the physiological effects of copeptin in infertile women with different ovarian reserve types. This study aimed to investigate the relationship of serum copeptin level with poor ovarian reserve (POR) and to reveal the predictive value of copeptin for POR development in the infertile women. Materials and Methods: All participant women were classified as the control group (n=77) included the women with diagnosis of unexplained infertility and the POR group (n=61) was composed of the women who met the European Society of Human Reproduction and Embryology consensus on POR [serum anti-Müllerian hormone (AMH) concentrations below 1.1 ng/mL]. The biochemical tests, including estradiol (E2), follicle stimulating hormone (FSH), luteinizing hormone, AMH and copeptin were analysed. The analyses of serum copeptin concentrations were measured by the means of competitive enzyme immunoassay. Results: A significant increase in the serum copeptin level existed only in the POR group. There was a significant positive correlation between serum copeptin with E2 and FSH levels in the POR group. Significant negative correlations between copeptin and AMH concentrations (r=-0.310, p=0.015) and between copeptin concentration and antral follicle counts (r=-0.284, p=0.027) were detected only in the POR group. The estimated areas under receiver operating characteristic curves for serum concentration were found to be statistically significant with a cut-off value of 3.52 (95% confidence interval 0.519-0.709), sensitivity 0.90 and specificity 0.72. Conclusion: This study confirmed that there was an elevated serum copeptin concentration in the infertile women with POR and that serum copeptin concentration may have a predictive value for POR diagnosis.

Can pycnogenol prevent cisplatin-induced damage in uterus and ovaries?

Introduction: Cisplatin is an antineoplastic agent, which is thought to act on tissues with increased levels of reactive oxygen species and decreased levels of antioxidants. Pycnogenol is a potent antioxidant that is used in medical conditions caused by oxidative stress. The aim of our study is to demonstrate the effects of pycnogenol on cisplatin-induced uterine and ovarian damage in rats. Material and methods: Wistar albino female rats were randomly divided into 3 groups before the experiment as follows: a 2.5 mg/kg cisplatin group (CG; n = 10), a 40 mg/kg pycnogenol + 2.5 mg/kg cisplatin group (PCG; n = 10), and a healthy control group (HG; n = 10). Then, the ovaries and uteri of the rats were examined to determine malondialdehyde (MDA), total glutathione (tGSH) and superoxide dismutase (SOD) biochemical levels and the histopathological findings. Results: Our study demonstrated that, in uterine and ovarian tissues of rats administered with cisplatin, there was a decrease in the levels of tGSH and SOD, while MDA was increased; however, it was observed that these ratios were reversed in the PCG group (p < 0.05). The number of follicles in the ovarian tissues was examined in all 3 groups. When the CG group was compared with the other two groups, the number of primordial, developing and atretic follicles was low, but there was no difference in the corpus luteum count. Conclusions: Pycnogenol pretreatment alleviates cisplatin-induced uterine and ovarian injury in rats because of its antioxidative effect.

Zinc and Magnesium Levels of Pregnant Women with Restless Leg Syndrome and Their Relationship with Anxiety: A Case-Control Study.

Restless leg syndrome (RLS) is a multifactorial movement disorder, and pregnancy is seen as a risk factor. This study aims to determine the clinical and psychiatric causes of RLS with a case-control study. The hemogram, biochemistry data, thyroid function tests, and serum element levels of healthy pregnant women (n = 134) and pregnant women diagnosed with RLS (n = 119) were compared. Total Ca, Mg, K, and Na concentrations were measured with an inductively coupled plasma optical emission spectrometry (ICP-OES), and an atomic absorption spectrophotometer was used to measure total concentrations of Zn in all samples. The Beck Anxiety Inventory (BAI), the Beck Depression Inventory (BDI), and the Pittsburg Sleep Quality Index (PSQI) scores were also compared in both groups. Sonographic measurements showed that the fetal biparietal diameter and femur lengths were higher in the RLS group (p = 0.001, p = 0.048, respectively), and abortion history was higher in the RLS group (p = 0.016). Magnesium and zinc levels were lower (p < 0.001 for both) and BAI and PSQI scores were higher (p < 0.001 for both) in the RLS group, and there was no difference between the BDI (p = 0.269) scores. A statistically significant relationship was detected between the BAI and RLS scores in the control and RLS groups (p < 0.001 for both). This is the first study to show that magnesium and zinc deficiency may play a role in the etiology of RLS during pregnancy; the results also showed adverse perinatal outcomes such as high miscarriage.

Effects of Oxygen Therapies in Experimental Acute Acoustic Trauma.

BACKGROUND: Acute acoustic trauma is defined as a sudden sensorineural hearing loss that occurs after an exposure to acoustic overstimulation. Increasing the oxygen in perilymph can be a treatment modality. Our study aims to investigate the influence of normobaric oxygen therapy on the recovery of acute acoustic trauma and to compare it with the hyperbaric oxygen therapy. METHODS: Three groups of rats (5 rats each) were exposed to white noise for 1 hour. Sensorineural hearing loss was identified using distortion product otoacoustic emission. Subsequently, the first group was treated with hyperbaric oxygen therapy, the second group was treated with normobaric oxygen therapy, and the third group did not receive any treatment and was used as a control group. RESULTS: There was a statistically significant difference within time for frequencies of 1, 1.5, and 2 kHz, but there was no statistically significant difference between groups. For frequencies of 3, 4, 5, and 6 kHz, there was a statistically significant difference within time and between groups. Between groups, recovery of distortion product otoacoustic emission values in all frequencies was better in the control group by the third, fifth, and seventh days. Comparing the values of hyperbaric oxygen therapy and normobaric oxygen therapy groups, it was observed that by the third day, the hyperbaric oxygen therapy values were better than those of the normobaric oxygen therapy values. However, by the fifth and seventh days, the normobaric oxygen therapy values were better (except at a frequency of 1 kHz). CONCLUSION: Because there is a high rate of spontaneous recovery, physicians should be more selective to treat patients with oxygen therapies.

Association of eleven single nucleotide polymorphisms with refractive disorders from Eskisehir, Turkey.

AIM: To investigate relationship between refractive errors and eleven single nucleotide polymorphisms (SNPs) in HGF, GC, MFN1, GNB4, and VDR genes in Turkish population. METHODS: A group of 212 participants with myopia (n=91), hyperopia (n=45), and emmetropia (n=76) were investigated in this study. SNPs in HGF, GC, MFN1, GNB4 and VDR genes were studied by SnapShot technique. RESULTS: The patients in this study consists of 47 female/44 male (age: 23.47±4.30) patients with myopia, 20 female/25 male (age: 31.20±8.02) with hyperopia and 33 female/43 male (age: 25.22±6.60) with emmetropia. The genotype distribution of the rs7618348 polymorphism, which was the only statistically significant one between myopia and emmetropia group. The genotype distribution of the rs3819545, rs3735520, rs7041, and rs2239182 polymorphisms, which were statistically significant between hyperopia and emmetropia groups. CONCLUSION: The importance of genetic predisposition to refractive errors with respect to etiology of the disease is revealed. It is known that polymorphism studies may differ because of genetic diversity among populations so larger cohort studies are required in different populations to enlighten the etiology of the refractive errors.
