Abstract
Tumor necrosis factor-alpha (TNF-α) has an important role in hypoxia/reoxygenation (H/R)-induced intestinal damage. It was shown that blocking TNF-α with infliximab has beneficial effects on experimental necrotizing enterocolitis and hypoxic intestinal injury. However, there is no data about the effect of adalimumab on H/R-induced intestinal damage. Therefore, we aimed to determine potential dose-dependent benefits of adalimumab in such damage in neonatal rats. Wistar albino rat pups were assigned to one of the four groups: control group, hypoxia group, low-dose adalimumab (5 mg/kg/day) treated group (LDAT), and high-dose adalimumab (50 mg/kg/day) treated group (HDAT). On the fourth day of the experiment, all rats except for the control group were exposed to H/R followed by euthanasia. Malondialdehyde (MDA), myeloperoxidase (MPO), TNF-α, total antioxidant capacity (TAC), and total oxidant capacity (TOC) were measured in intestinal tissue. TAC and TOC values were used to calculate the oxidative stress index (OSI). Histopathological injury scores (HIS) were also evaluated in the tissue samples. MDA levels were significantly lower in the LDAT and HDAT groups (p < 0.001). TNF-α levels were significantly lower in the LDAT group (p < 0.001). OSI was significantly higher in the H/R group than in the control and LDAT groups (p < 0.001). Mean HIS values in the LDAT group were significantly lower than those in the H/R and HDAT groups (p < 0.001). This experimental study showed that low-dose adalimumab appears to have a beneficial effect on intestinal injury induced with H/R in neonatal rats.

Abstract
Many factors can cause depression including genes (DNA), brain chemistry or stress. Antidepressant drugs affect the brain, heart, liver and kidney. We investigated the effects of the antidepressant drugs, amitriptyline (AMI) and paroxetine (PARO) on kidney. We used 24 adult female rats that were ovariectomized bilaterally 7 days before the experiment. The ovariectomized (OVX) animals and healthy control rats were divided into four equal groups for 4 weeks: control group, OVX control group (sham), AMI group and PARO group. Following the experimental period, the Cavalieri method was applied to sections of the kidney. PARO produced adverse effects on distal and proximal tubule volume, but AMI had no effect on the volume of distal and proximal tubules. Both PARO and AMI decreased the volume of Bowman spaces. PARO also damaged the kidney tubules and cells.

Abstract
This study was designed to determine serum human leukocyte antigen-G (HLA-G) levels and establish whether serum HLA-G level is related with insulin resistance, oxidative stress, dyslipidemia and ovarian hyperandrogenism in women with polycystic ovary syndrome (PCOS). Twenty-five patients with PCOS and 23 healthy control women were evaluated in this study. Serum HLA-G, lipid fractions, glucose, insulin, malondialdehyde (MDA), glutathione (GSH), white blood cell (WBC), sex hormone-binding globulin (SHBG) and other hormone (gonadotropins and androgens) levels were measured. The estimate of insulin resistance was calculated by homeostasis model assessment (HOMA-IR). Serum luteinizing hormone (LH), total testosterone, fasting insulin, WBC levels and LH/follicle-stimulating hormone (FSH) ratio, free androgen index (FAI) and HOMA-IR values were significantly higher in patients with PCOS compared with healthy women. However, the women with PCOS had considerably lower serum FSH, SHBG, MDA, GSH and HLA-G levels than healthy subjects. HLA-G was inversely related with HOMA-IR, FAI, LH/FSH ratio and WBC, but positively with high-density lipoprotein cholesterol. Decreased serum HLA-G level may be related with insulin resistance, ovarian hyperandrogenism and oxidative stress in women with PCOS. Nevertheless, the exact role of HLA-G in the pathogenesis of the disease remains to be elucidated.

Abstract
This study was designed to determine serum Fetuin-A levels and establish whether serum Fetuin-A level is related with insulin resistance, oxidative stress, ovarian hyperandrogenism and dyslipidemia in women with polycystic ovary syndrome (PCOS). Twenty-two patients with PCOS and twenty-one healthy control women were evaluated in this controlled clinical study. Serum Fetuin-A, lipid fractions, glucose, insulin, malondialdehyde (MDA), myeloperoxidase (MPO), glutathione (GSH), superoxide dismutase (SOD) and other hormone (gonadotropins, androgens) levels were measured. The estimate of insulin resistance was calculated by homeostasis model assessment (HOMA-R). The women with PCOS had significantly higher serum fasting glucose, insulin, luteinizing hormone (LH), MDA, Fetuin-A levels, and LH/follicle-stimulating hormone (FSH) ratio, free androgen index (FAI), HOMA-IR than healthy women. However, sex hormone-binding globulin (SHBG) and GSH levels were significantly lower in patients with PCOS compared with controls. Fetuin-A was positively correlated with insulin, HOMA-IR and FAI. Multiple regression analysis revealed that FAI was strong predictor of serum Fetuin-A level. Serum Fetuin-A level was related with insulin resistance and ovarian hyperandrogenism in women with PCOS. These results suggest that Fetuin-A may have a role in triggering the processes leading to insulin resistance and androgen excess in PCOS.

Abstract
The aim of this work was to evaluate the effects of therapeutic doses of Cimicifuga racemosa on cardiovascular parameters and on liver lipid metabolism and redox status in an animal model of estrogen deficiency associated with hypertension, a condition that could make the liver more vulnerable to drug-induced injuries. Female Wistar rats were subjected to the surgical procedures of bilateral ovariectomy (OVX) and induction of renovascular hypertension (two-kidneys, one-clip; 2K1C). These animals (OVX + 2K1C) were treated with daily doses of a C. racemosa extract, using a dose that is similar to that recommended to postmenopausal women (0.6 mg/kg), over a period of 15 days. The results were compared to those of untreated OVX + 2K1C, OVX, and control rats. The treatment with C. racemosa caused a significant reduction in blood pressure. In the liver, treatment did not prevent the development of steatosis, and it reduced the mitochondrial and peroxisomal capacity to oxidize octanoyl-CoA compared to the untreated animals. In addition, C. racemosa caused numerous undesirable effects on the liver redox status: it increased the mitochondrial reactive oxygen species generation, an event that was not accompanied by an increase in the activity of superoxide dismutase, and it induced a decrease in peroxisomal catalase activity. Although the reduced glutathione content had not been affected, a phenomenon that probably reflected the restoration of glucose-6-phosphate dehydrogenase activity by C. racemosa, oxidative damage was evidenced by the elevated level of thiobarbituric acid-reactive substances found in the liver of treated animals.

Abstract
Taking into account the sexual dimorphism previously reported regarding mitochondrial function and biogenesis in brown adipose tissue, the aim of the present study was to go further into these differences by investigating the effect of ovariectomy and 17-β estradiol (E2) replacement on brown adipose tissue mitochondrial function. In this study, fourteen-week-old control female and ovariectomized female Wistar rats were used. Rats were ovariectomized at 5 weeks of age and were treated every 2 days with placebo (OVX group) or E2 (10 μg/kg) (OVX+E2 group) for 4 weeks before sacrifice. We studied the levels of oxidative capacity, antioxidant defence and oxidative damage markers in brown adipose tissue. Moreover, the levels of key elements of mitochondrial biogenesis as well as UCP1 protein levels, as an index of mitochondrial thermogenic capacity, were also determined. In response to ovariectomy, mitochondrial proliferation increased, resulting in less functional mitochondria, since oxidative capacity and antioxidant defences decreased. Although E2 supplementation was able to restore the serum levels of E2 shown by control rats, the treatment reverted the effects of the ovariectomy only in part, and oxidative and antioxidant capacities in OVX+E2 rats did not reach the levels shown by control females. Taking these results into account, we suggest that ovarian hormones are responsible, at least in part, for the sexual dimorphism in BAT mitochondrial function. However, other signals produced by ovary, rather than E2, would play an important role in the control of mitochondrial function in BAT.
