Abstract
OBJECTIVES We aimed to investigate the effects of asprosin on diabetes with a focus on serum glucose, irisin, ghrelin, leptin levels and hepatic levels of triglycerides (TG), cholesterol, low-density lipoprotein (LDL). METHODS Asprosin (10 µg/kg) was administered intraperitoneally four times at 3-day intervals and then blood and hepatic parameters above mentioned were investigated in control and diabetic mice. RESULTS The administration of asprosin increased blood glucose level in healthy animals (p = .05) whereas it did not change blood glucose level in diabetic animals. In addition, while asprosin decreased irisin level and increased ghrelin level, it did not change leptin level in diabetic mice. Therewithal, asprosin decreased the increasing levels in hepatic TG, cholesterol, and LDL in diabetic mice. CONCLUSIONS Our novel findings implicate that asprosin may be a target molecule in preventing the development and complications of diabetes.

Abstract
Excessive high fructose corn syrup (HFCS) consumption is known to cause oxidative stress, which induces transient receptor potential melastatin type 2 (TRPM2) channel gating. Oxidative stress-induced TRPM2 gating is suggested to play an important role in neurons, indicating a role for the TRPM2 channel in a variety of neuropsychiatric disorders including depression and anxiety. We investigated the effects of HFCS and chronic immobilization stress (CIS) on TRPM2 channel immunoreactivity, anxiety, and depressive-like behaviors in adult male rats. The male rats (n=8/group) were divided into 4 groups: Control, 20% HFCS (F20), 40% HFCS (F40), and stress. The control group received tap water, and F20 and F40 groups were exposed to HFCS 20% and 40% respectively for 14 consecutive days. Rats in the stress group were subjected to immobilization stress for 3 or 6 hours daily in the first and second weeks to induce CIS. Then, light/dark tests, open field tests (OFT), and tail suspension tests (TST) were performed, respectively. In the light/dark test, the time spent in the dark chamber significantly increased in all groups vs the control group (P<0.01). In support of this result, time spent in the light chamber significantly decreased in all groups vs the control group (P<0.01). Besides, CIS significantly increased depressive-like behavior in the stress group vs the control group (P<0.05). In serum hormone levels, corticosterone (CORT) levels significantly increased in the F40 and stress groups vs the control group (P<0.01). TRPM2 immunoreactivity significantly increased in the hippocampus, prefrontal cortex (PFC), nucleus accumbens (NaC), and amygdala regions by HFCS and CIS treatments. For the first time in the present study, showed that f increased immunoreactivity of the TRPM2 cation channels may be linked to the anxiety-like behavior induced by HFCS.

Abstract
OBJECTIVES The aim of our study is to examine maternal serum Elabela levels in pregnancy with intrauterine growth retardation (IUGR). IUGR is one of the most important causes of perinatal mortality and morbidity. IUGR is also related future comorobidities such as diabetes mellitus, hyperlipidemia, hypertension and coronary artery disease. MATERIAL AND METHODS Fifty pregnancies diagnosed as IUGR (Group 1) and fifty healthy pregnancies (Group 2) enrolled into the study. Obstetric and demographic characteristics of the patients, serum elabela levels, ultrasound parameters, cord pH value and APGAR scores of the newborns were recorded. In the study, which was planned as a prospective case-control study, an independent t test was used for the evaluation of continuous data and the Mann Whitney U test was used for the statistical evaluation of ordinal data. p < 0.05 was considered significant. RESULTS The mean gestational age of the cases at delivery was 36.35 ± 1.29 in Group 1 and 38.16 ± 0.94 weeks in Group 2 (p < 0.05). Mean serum Elabela levels were 15.05 ± 9.03 in Group 1 and 8.96 ± 4.33 ng/mL in Group 2 (p < 0.0001). Mean newborn weights were 2498.20 ± 465.92 in Group 1 and 3179.44 ± 387.99 gr. in Group 2 (p < 0.0001). Systolic and diastolic blood pressure measurements taken on the day of delivery were higher in Group 1, and diastolic blood pressure was 77.0 ± 9.53 in Group 1 and 72.60 ± 13.37 mmHg in Group 2 (p < 0.05). Bilateral uterine artery Pulsatile Index (PI) and umbilical artery PI value were significantly higher in Group 1 (p < 0.05), and middle cerebral artery PI and cerebroplacental ratio were significantly lower in Group 1 compared to Group 2 (p < 0.05). Although the cord pH value, 1st and 5th minute APGAR scores were lower in Group 1 compared to Group 2, no statistically significant difference was found (p > 0.05). CONLUSIONS In our study, it was found that serum Elabela levels increased significantly in pregnancies complicated by IUGR compared to the control group.

Abstract
Physical exercise and body muscle/fat mass are known to affect the endocrine system, puberty onset and reproductive health. However, the potential effects of irisin, an adipo-myokine and exercise-induced hormone, have not yet been fully elucidated on reproductive maturation. Therefore, the present study aimed to determine the effects of irisin administration on pubertal maturation and reproductive system in female and male rats. Daily i.p. injection of irisin (100 ng/kg; from postnatal day 21 for about 10 weeks) delayed the ages at the vaginal opening (as an external index of puberty onset) and first estrus. Furthermore, continuous administration of irisin to female rats caused a significant decrease in serum follicle-stimulating hormone levels and an increase in serum luteinizing hormone and 17β-estradiol levels, as well as causing histopathological changes in the ovarian tissue. On the contrary, irisin administration to male rats did not modify the timing of puberty, as estimated by age at preputial separation. However, chronic exposure to irisin produced significant increases in serum luteinizing hormone and testosterone levels and also sperm concentration and seminiferous tubule diameter in male rats. In conclusion, irisin exposure has different effects on both pubertal maturation and reproductive system in female and male rats. The present findings reveal that chronic irisin exposure may lead to disorders in the female reproductive system and may have androgenic potential on the hypothalamic-pituitary-gonadal axis in males.

Abstract
OBJECTIVES Reproduction is one of the physiological functions that are often negatively affected by chronic stress. We aimed to examine effects of two distinct 7-day chronic immobilization stress (IMO) models on gonadotropins levels and depression-like behaviors in female rats. METHODS Adult Wistar albino female rats were divided into three groups as follows (n=7 for each group): control, IMO-1 (45 min daily for 7-day) and IMO-2 (45 min twice a day for 7-day). Neuropsychiatric behaviors were determined by using forced swimming test (FST) and open field test (OFT). Gonadotropins were analyzed using ELISA tests. RESULTS In FST, swimming was lower, and immobility was higher in the IMO-1 group and IMO--2 group. Climbing score of the IMO-2 group was higher compared to the control group. In OFT, there was no significant alteration in the mean velocity, total distance, duration of time spent in the central area and duration of latency in the central area between the stress groups and the control group. Final body weight and percentage of body weight change were lower in both stress groups. The follicle-stimulating hormone level was lower only in the IMO-2 group, and the luteinizing hormone concentrations were significantly lower in the IMO-1 group and IMO-2 group. CONCLUSIONS Our results indicated that depression-like behaviors increased, and gonadotropins decreased in the female rats exposed to 7-day chronic IMO.

Abstract
The aim of the study was to examine possible impacts of paroxetine and agomelatine on the levels of some components that constitute the seminal vesicle fluid. As a second purpose, it was also aimed to examine how possible negative effects induced by paroxetine on seminal vesicle fluid components were affected by kisspeptin and RF9 (an RFamide-related peptide antagonist, RFRP). Forty-two male rats, aged 21 days, divided into six groups; control, sham, paroxetine, agomelatine, paroxetine + kisspeptin and paroxetine + RF9. Paroxetine (3.6 mg/kg) and agomelatine (10 mg/kg) were administrated by oral gavage. Kisspeptin (1 nmol) and RF9 (20 nmol) were administered intracerebroventricular (i.c.v). The experiments were ended on post-natal 120 days; fructose, vitamin E, sodium, potassium and magnesium levels were measured in seminal vesicle fluid. Fructose, vitamin E, magnesium and potassium levels were significantly decreased in seminal vesicle fluid from the rats treated with paroxetine but did not show significant differences following agomelatine administration. The co-administration of kisspeptin or RF9 with paroxetine prevented the paroxetine-induced negative effects on seminal vesicle fluid components. These results suggest that reduction in sperm fertilising ability caused by changes in seminal vesicle fluid can be seen in long-term antidepressant use. RF-9 and kisspeptin might have positive effects on long-term antidepressant use-induced infertility.

Abstract
Aim The aim of the present study was to assess the protective effects of magnesium sulfate (MgSO4) on ischemia/reperfusion (I/R) induced ovarian damage in a rat ovarian torsion model. Methods Forty-two female Sprague Dawley rats were included in the study. They were divided into six groups as Group 1, sham; Group 2, bilateral ovarian torsion; Group 3, bilateral ovarian torsion–detorsion; Group 4, MgSO4–sham; Group 5, MgSO4–bilateral ovarian torsion; Group 6, bilateral ovarian torsion–MgSO4–detorsion. Both torsion and detorsion periods lasted 3 hours. In Groups 4, 5 and 6, MgSO4 (600 mg/kg) was administered by intraperitoneal route 30 minutes before sham operation, torsion and detorsion, respectively. At the end of the study period, both ovaries were removed. One of the ovaries was used for histopathological analyses and the other for biochemical analyses. Results In the torsion–detorsion group, all the histopathological scores were higher compared to the sham and torsion only group (p<0.05). Administration of MgSO4 only caused significant decrease in the inflammatory cell scores of the torsion–detorsion group (p<0.05). MgSO4, whether given before torsion or before detorsion, suppressed malondialdehyde levels when compared to the untreated groups (p<0.01 and p<0.001, respectively). Glutathione peroxidase activities were significantly higher in the MgSO4 applied torsion and detorsion groups than Groups 2 and 3 (p<0.05, for both). Administration of MgSO4 also caused an increase in glutathione levels in the torsion and detorsion groups compared to the torsion only and detorsion only groups (p<0.05, for both). Also, total oxidant status levels decreased in the MgSO4 applied torsion and detorsion groups compared to the untreated corresponding ones (p<0.01 and p<0.001, respectively). MgSO4 significantly decreased the Oxidative Stress Index levels in the torsion–detorsion group compared to Group 2 (p<0.001). Conclusion Histopathological and biochemical analysis revealed that prophylactic treatment with MgSO4 reduces the changes observed in I/R injury in a rat model.

Abstract
OBJECTIVES This study aimed to investigate the protective effect and antioxidant activity of an herbal product that made from multiple plants in a rat model of kidney dysfunction induced by intraperitoneal cisplatin. MATERIALS AND METHODS Twenty-four rats were divided into four different groups namely: Group 1 - control healthy animals without any specific medication, Group 2 - Herbal product only 5 mg/kg, Group 3 - cisplatin only and Group 4 - Herbal product 5 mg/kg + cisplatin. RESULTS Evaluation of our findings demonstrated a significant (p = 0.017) reduction in Catalase activities and a significant increase (p = 0.001) in renal tissue Malondialdehyde levels in cisplatin- treated rats when compared with the control group. Also, Glutathion and Glutathione peroxidase content revealed significant (p = 0.031) reduction in renal tissues of cisplatintreated rats compared with the control group. Pre-treatment of rats with the herbal product ameliorated these cisplatininduced changes of the antioxidant enzymes. No statistically significant changes were demonstrated in Superoxide dismutase activities in the tissue specimens of any group. CONCLUSIONS This potent antioxidant herbal medicine was found to have potential antioxidant activity, which may in turn to be effective in the protection of kidney tissue resulting from cisplatin application. Therefore, much attention should be given to the possible role of natural dietary antioxidants for protecting the kidney.
