[Show abstract][Hide abstract] ABSTRACT: Objectives: Positive relation between body mass and bone mineral density (BMD) is thought to be due to weight bearing
effect. However, adipose tissue derived adipokines may have important effects on bone. Obese women have decreased levels
of omentin in circulation which is related with adverse metabolic events. The hypothesis was that performed in this study, we
aimed to study the association of omentin levels with body composition and BMD in non-diabetic postmenopausal women.
Methods: Postmenopausal women aged 40 to 70 years, scheduled for BMD testing were prospectively evaluated. Patients
with known diabetes, chronic renal failure, chronic liver disease, malabsorption, inflammatory bowel disease, <40 and >70
years of age were excluded. BMD and body composition were measured by DXA (GE-Lunar DPX pro). Fasting blood samples
were obtained for analysis of complete blood count, glucose, creatinine, lipid profile and omentin. Statistical analyses were
performed by using SPSS version 18 for windows. P<0.05 was considered statistically significant.
Results: Mean age of the patients in the osteoporosis group was higher than that of the control group (59.1±7.6 vs 53.3±5.7,
p<0.05). Mean omentin level was higher in osteoporosis group than in osteopenia and control groups (479.7±141.6 vs
342.3±173.6 and 346.8±127.2, p<0.05). Total body fat mass, muscle mass and the T score of lumbar spine had a negative
correlation with omentin levels (r=-0.252, -0.276, -0.344, p<0.05).
Conclusions: Body composition does not seem to effect omentin levels. Women with a lower BMI have increased omentin
levels. Higher omentin levels are associated with lower T scores at the lumbar spine.
[Show abstract][Hide abstract] ABSTRACT: The aim of this study was to determine serum and aqueous xanthine oxidase (XO) levels, and mRNA expression in anterior lens epithelial cells in pseudoexfoliation (PEX).
In this prospective study, serum, aqueous and anterior lens capsules were taken from 21 patients with PEX and 23 normal subjects who had undergone routine cataract surgery. Serum and aqueous XO levels were analyzed using the colorimetric method. mRNA expression of XO in anterior lens epithelial cells was evaluated using reverse transcription polymerase chain reaction analysis.
Serum XO levels (means ± standard deviations) were 207.0 ± 86.1 IU/mL and 240.6 ± 114.1 IU/mL in the normal and PEX groups, respectively (p = 0.310). Aqueous XO levels (means ± standard deviations) were 65.5 ± 54.3 IU/mL in the normal group and 130.5 ± 117.4 IU/mL in the PEX group (p = 0.028). There was a 2.9 fold decrease in mRNA expression in anterior lens epithelial cells of PEX, which is significantly lower than the normal group (p = 0.01).
Higher aqueous XO levels lacking associated different serum XO suggests higher oxidative stress in the aqueous. Higher aqueous XO levels in PEX with decreased mRNA expression in anterior lens epithelial cells indicate possible overexpression of XO in other structures related to the aqueous.

[Show abstract][Hide abstract] ABSTRACT: Purpose. The pathogenesis of pseudoexfoliation (PEX), the most common cause of secondary glaucoma, has not been clearly identified, but there is increasing evidence that points out the role of oxidative stress. The aim of this study is to evaluate some of the most commonly used blood parameters, hemoglobin (Hb), red blood cell count (RBC), alanine aminotransferase (ALT), and uric acid (UA) levels, in subjects with PEX. Materials and Methods. This study is performed in a state hospital between November 2011 and December 2012. Retrospective chart review of subjects who underwent cataract surgery was performed. Thirty-one healthy subjects with PEX and 34 healthy subjects without PEX were evaluated. Hb, RBC, ALT, and UA levels were recorded. Student's t-test was used to compare the two groups. Results. The mean age was 73.6 ± 14.1 years in PEX group and 70.1 ± 12.7 in control group (í µí± = 0.293). Hb, RBC, ALT, and UA levels did not show a statistically significant difference among PEX and control groups (í µí± > 0.05 for all). Conclusion. Serum levels of Hb, RBC, ALT, and UA levels were similar in subjects with and without PEX. Further studies are needed to clarify the precise role of Hb, RBC, ALT, and UA in the pathogenesis of PEX.

[Show abstract][Hide abstract] ABSTRACT: Acute mesenteric ischemia (AMI) is an intestinal vascular disease with high mortality. Clinical diagnosis of acute mesenteric ischemia is difficult. Adipose tissue is an important mediator of metabolism and inflammation.Omentin is produced by visceral adipose tissue and decreased serum levels of omentin are associated with poor metabolic outcomes. We aimed to investigate whether serum omentin level predicts early diagnosis of AMI before development of transmural ischemia.
Twenty-four Sprague Dawley rats weighted about 200-250 gr grouped in 3 experimental groups as sham, transient ischemia and permanent ischemia. Each group consisted of 8 rats. Blood samples were evaluated to determine serum urea, creatinine, omentin and C-reactive protein (CRP) levels. A blinded histological examination performed with the same histologist for hemotoxileneosine painted ileal tissue samples.
Mean serum omentin level in sham group (27.5±4.67) was significantly elevated compared to rats in Ischemia-reperfusion (IR) group (10.9±9.01).The difference reached the statistical significance (p=0.004). Serum omentin levels were not correlated to urea, creatinine or CRPlevels.
Omentin levels may be a biochemical indicator to detect AMI. However, further human studies are needed (Tab. 3, Fig. 3, Ref. 34).

[Show abstract][Hide abstract] ABSTRACT: Chronic obstructive pulmonary disease (COPD) is a complex chronic inflammatory disease of the lungs in which inflammatory markers are involved with significant extrapulmonary effects that may contribute to its severity and complications. Moreover, some of the inflammatory markers such as C-reactive protein (CRP) are associated with COPD. Pentraxin 3 (PTX3) is the member of long pentraxins. The aim of the present study was to investigate the level of PTX3 in patients with COPD. Fifty-four COPD patients and 31 controls were enrolled in this study. Demographical data such as age, sex, cigarette smoking status, comorbidities, drugs, habits, and modified Medical Research Council (MMRC) dyspnea scores were recorded. All patients were asked for COPD Assessment Test™ (CAT). The mean age was 65.7 ± 9.8 years, 92 % male. Plasma levels of PTX3 were found to be markedly higher in COPD patients [1.65 (0.32-12.72) ng/ml] than in controls [1.05 (0.43-3.26) ng/ml; p = 0.005]. On the other hand, PTX3 values did not differ between COPD stages [A, 1.73 (0.69-11.03); B, 1.49 (0.84-12.52); C, 0.79 (0.52-1.06); and D, 2.09 (0.32-12.72); p = 0.27]. The plasma PTX3 levels were positively correlated with MMRC scores. We conclude that circulating PTX3 levels are elevated in COPD patients. Plasma levels of PTX3 were correlated with dyspnea (MMRC scores). But PTX3 levels were not correlated with the severity of COPD.
[Show abstract][Hide abstract] ABSTRACT: Purpose::
Omentin, a member of the adipocytokines family, is derived from adipose tissue and a lower level of serum omentin is considered as a metabolic risk factor. The aim of the present study is to evaluate the serum levels of omentin in patients with pseudoexfoliation syndrome (PES).
Materials and methods::
Patients without any systemic or ocular disease other than PES were included in the study. Age-matched and sex-matched healthy volunteers without PES were accepted as a control group. After detailed ophthalmologic examination, blood samples were obtained from a forearm vein. Serum levels of omentin were determined by the method of enzyme-linked immunosorbent assay.
The mean age of the PES group (12 females, 12 males, n=24) was 75.2±8.4 years, and the control group (10 females, 10 males, n=20) was 75±6.7 years. There was no difference between the groups in terms of age (P=0.93) and sex (P=0.9). The mean serum levels of omentin in the PES group were 801.5±317.1 ng/mL and in the control group were 1150.1±584.1 ng/mL. The mean serum omentin levels were significantly lower in patients with PES (P=0.016).
Lower levels of serum omentin in patients with PES compared with healthy subjects may support the theory of systemic nature of the disease.

[Show abstract][Hide abstract] ABSTRACT: Background:
Inflammatory mechanisms are reported to play important roles in the pathophysiology of schizophrenia. The neutrophil-lymphocyte ratio (NLR) is a simple and easily accessible indicator of the systemic inflammatory response. Our goal was to investigate whether NLR was higher in patients with schizophrenia than in healthy comparison subjects similar in age, sex, and body mass index.
Subjects and methods:
In this multicenter cross-sectional study, we analyzed 156 non-obese patients with schizophrenia and 89 healthy control subjects for complete blood count. The Brief Psychiatric Rating Scale was used to determine the severity of clinical pathology.
The mean ± SD NLR of patients with schizophrenia was significantly higher than that of healthy controls (2.6 ± 1.1 vs. 1.9 ± 0.6, respectively, p < 0.001). NLR did not significantly correlate with severity and duration of schizophrenia (r = 0.065. p > 0.05).
Our findings suggest that NLR levels are increased in physically healthy, non-obese, patients with schizophrenia when compared with physically and mentally healthy individuals. To our knowledge, this is the first study that demonstrated the association between NLR and schizophrenia.
[Show abstract][Hide abstract] ABSTRACT: AimPsoriatic arthritis (PsA) is an inflammatory form of arthritis typically associated with psoriasis and/or psoriatic nail disease. Adipocytokines were once thought to influence development of (only) insulin resistance and diabetes mellitus. However, it is now clear that adipocytokines play important roles in development of the inflammation associated with either autoimmune or auto-inflammatory disorders. In the present study, we measured changes in the serum levels of adiponectin, resistin and visfatin, and the associations of such changes with the extent of disease activity and insulin resistance in PsA patients.Material and methodsA total of 67 subjects (28 with PsA and 39 healthy controls) without hypertension or diabetes mellitus were enrolled. Adiponectin, resistin and visfatin levels, and the extent of insulin resistance (assayed using the homeostasis model [HOMA-IR]), were measured in all subjects. Assessment of PsA disease activity was done with the Disease Activity Index for Psoriatic Arthritis (DAPSA).ResultsPsoriatic arthritis patients had considerably higher serum levels of adiponectin, resistin and visfatin than did healthy controls (all P < 0.05). In the logistic regression analysis, the following variables may contribute to complex pathogenesis of PsA: adiponectin (P = 0.001, OR = 3.1, 95% CI = 1.6–6.0), resistin (P = 006, OR = 1.8, 95% CI = 1.2–2.9) and visfatin (P = 0.031, OR = 3.9, 95% CI = 1.1–13.9). In contrast, we have not detected any correlation between DAPSA and adipocytokine serum levels (P > 0.05).Conclusion
There is no correlation between adipocytokines and disease activity. Although serum adiponectin, resistin and visfatin levels are higher in patients with PsA, pathophysiological significance of the result has to be evaluated with more extensive studies.

[Show abstract][Hide abstract] ABSTRACT: Aims:
We aimed to investigate plasma omentin concentrations in non-obese, drug-free patients with schizophrenia in comparison with healthy volunteers.
Thirty-two patients with schizophrenia and 33 control subjects were recruited. Plasma omentin levels were determined by enzyme-linked immunosorbent assay.
Plasma levels of omentin (ng/ml) were found to be markedly lower in patients with schizophrenia (median = 7.7, 25th percentile = 6.3, 75th percentile = 604.9) than in controls (median = 486, 25th percentile = 326, 75th percentile = 794.2, p < 0.01). No significant difference was found between drug-free (n = 23) and drug-naive (n = 9) patients with respect to plasma omentin levels. Omentin concentrations correlated negatively with severity of illness, suggesting that patients with more severe pathology had lower fasting levels of omentin (n = 32; r = -0.387; p = 0.029).
The present results suggest that plasma omentin levels are decreased in physically healthy, non-obese, antipsychotic-free patients with schizophrenia when compared with physically and mentally healthy individuals. To our knowledge, this is the first study that demonstrated the association between omentin and schizophrenia.
[Show abstract][Hide abstract] ABSTRACT: Objective:
To evaluate intraperitoneal administration of Nigella sativa (NS) to prevent postoperative intraperitoneal adhesion (PPA) after surgical manipulation of rat uterine horn.
Materials and methods:
Two forms of NS were used in the study (Volatile oil (NSVO) and the ethanolic extract (NSEE)). A total of 50 rats were randomly assigned to the sham group (n = 10), control group (n = 10), NSVO group (n = 10), NSEE group (n = 10), and the Seprafilm group(n = 10). After 14 days, rats were sacrificed. Adhesions were examined macroscopically, and degree of adhesions was scored. A part of horn was excised, and superoxide dismutase (SOD) and glutathione peroxidase activities as well as malondialdehyde levels were evaluated, and histological score was calculated.
Total microscopic score of the NSEE group was significantly lower than the control group (p = .001) and was marginally significantly lower than the seprafilm group (p = .005). Collagen formation score was higher in the seprafilm group compared to the sham and NSEE groups (p < 0.001, p = .003, respectively). Apoptotic cells were lower in the NSEE group compared to the control group (p = .003) and also lower in the NSEE and NSVO groups compared to the seprafilm group (p = .001, p < .001, respectively). Only SOD activity was higher in the NSVO and seprafilm groups compared to the control group (p < .001).
NSEE form seems to have a possible effect in the prevention of PPAs. This may occur by its effect in decreasing collagen formation and by decreasing apoptosis in the injured tissues. NSVO form seems to induce SOD. Therefore, combined use of NSVO with seprafilm may increase the adhesion preventive effect of seprafilm.

[Show abstract][Hide abstract] ABSTRACT: Introduction:
Many of studies have shown that increased lipid levels play a significant role in the pathogenesis of atherosclerosis after splenectomy. We investigated the effects of N-acetyl cysteine (NAC) on lipid parameters and leukocyte and platelet (PLT) levels following splenectomy.
Materials and methods:
32 Sprague-Dawley rats weighing from 200 to 250 g were placed into four experimental groups. For 42 days post-operatively, all rats were fed standard rat food and water and the rats in the first group ( n = 8) received no intraperitoneal infusion. Rats in the second group ( n = 6) were given a 50 mg/kg saline solution (SF); those in the third group ( n = 8) received 50 mg/kg NAC and the rats in the fourth group ( n = 8) were administered a 100 mg/kg NAC infusion intraperitoneally.
All parameters other than white blood cell count were significantly different between the four groups. There were no significant differences between the control and SF groups in terms of total cholesterol and PLT levels. Triglyceride (TG), very-low-density lipoprotein (VLDL) and high-density lipoprotein (HDL) levels were significantly elevated in the SF group compared with the control rats. There was no statistically significant difference between the SF and NAC 50/100 groups in terms of low-density lipoprotein levels. Total cholesterol, TG, HDL and VLDL levels were significantly reduced and the PLT level was significantly elevated in the NAC 50 and NAC 100 groups compared with the SF group.
Serum VLDL and TG levels should be monitored in patients after splenectomy. For reduction in these lipid parameters, early NAC treatment should be initiated. More prospective larger studies are needed to confirm our results.

[Show abstract][Hide abstract] ABSTRACT: Acute pancreatitis is an acute inflammation of the parenchyma of the pancreas. Several adipokines have been investigated in acute pancreatitis, and these cytokines contribute to inflammation in acute pancreatitis. However, not enough data exist regarding omentin in injuries of the pancreas. Because of a possible common pathogenesis, we aimed to study the association between pancreatic damage and serum omentin levels.
wenty-four Sprague Dowley rats weighing 200-250 g were randomly placed into three groups: a sham group (n=8), an acute pancreatitis group (n=8), and a chronic pancreatitis group (n=8). Both rats in the sham group underwent laparotomy, and 0.1 cc of saline solution was injected through the pancreatic canal. On the seventh day, a blood sample was obtained by abdominal aorta puncture, and the pancreas was resected for histological examination. In the acute and chronic pancreatitis groups, 0.1 cc of 4.5% Sodium Taurocholote was injected through the pancreatic canal. Blood samples were obtained and pancreatic resection was performed after 24 hours for the acute pancreatitis group and after 7 days for the chronic pancreatitis group.
Serum omentin levels of rats with chronic pancreatitis (49.37±2.82 ng/ml) were increased compared to both acute pancreatitis (37.79±1.24 ng/ml) (p<0.01) and sham rats (22.49±1.4 ng/ml) (p<0.01). In addition, the omentin level of rats with acute pancreatitis was significantly increased compared to the sham group (p<0.01).
The elevation in omentin levels in rats in the early stage of pancreatitis was due to the anti-inflammatory effects of omentin; hence, elevated omentin levels improved insulin resistance and caused a significant reduction in glucose levels.

[Show abstract][Hide abstract] ABSTRACT: Asymmetric dimethylarginine (ADMA), the main endogenous inhibitor of nitric oxide synthase, is considered to be associated with endothelial dysfunction. High ADMA levels have been shown to be related with disorders causing vascular inflammation such as hypertension, hypercholesterolemia, atherosclerosis, chronic heart failure, stroke and sepsis. Cutaneous anthrax (CA) is a serious infectious disease which may cause vasculitis. The aim of the study was to investigate the serum ADMA levels in patients with CA.
A total of 35 serum samples of the patients with CA and 18 control sera were tested for ADMA levels using ADMA ELISA kit (Immunodiagnostik AG, Bensheim, Germany).
ADMA levels were found to be significantly higher in the patients group than the controls (p < 0.001). In addition, ADMA levels were found to be positively associated with sedimentation rates (R = 0.413; p = 0.026), and inversely associated with international normalized ratio (INR) levels (R = -0.46; p = 0.011). A cut-off value of 0.475 of ADMA had a sensitivity of 74.3%, specificity of 77.8%, and accuracy of 75.5% in the diagnosis of CA.
Although the exact mechanism still remains unclear, ADMA levels could be related to immune activation in CA. In addition, these data might suggest the higher ADMA levels in patients could be due to the perivascular inflammation and vasculitis in CA.

[Show abstract][Hide abstract] ABSTRACT: The diagnosis of acute appendicitis is based on medical history and physical examination. Serum (S) amiloid A (AA) levels are elevated in many inflammatory conditions. Omentin is a recently discovered adipokine showing decreased levels associated with inflammatory conditions. We aimed to measure SAA and omentin levels in patients with acute appendicitis.
36 patients with a diagnosis of acute appendicitis and 30 healthy subjects were enrolled to this research study. A statistical analysis was performed using IBM SPSS Statistics Version 16.0 (SPSS Inc.®, Chicago, IL, United States).
Patients in study group were significantly older than healthy control subjects (p=0.013). Body mass index of the patients with acute appendicitis (23.2±1.3) was greater than that of the control group (22.7±1), but the difference did not reach the statistically significance (p=0.076). ). Mean level of SAA was significantly raised in study group compared to healthy control subjects (p< 0.001). Mean omentin level was significantly lower in study group compared to healthy subjects (p=0.013).
In conclusion, although diagnosis of acute appendicitis is mostly based on clinical findings, omentin and especially SAA measurement in serum may help surgeons to avoid negative laparatomy.

[Show abstract][Hide abstract] ABSTRACT: Decreased plasma levels of omentin, a relatively novel adipokine, are shown to be associated with metabolic abnormalities and proinflammatory states. Although other adipokines such as leptin and adiponectin have been extensively investigated in patients with major depressive disorder (MDD), no studies have evaluated omentin levels in major depression. Therefore, this study sought to test the hypothesis that drug-naive patients with MDD would have lower serum omentin levels than a healthy control group similar in age, sex, and body mass index.
Thirty patients with MDD (10 men) and 30 healthy control subjects (10 men) were studied. Plasma concentration of omentin, along with other biochemical parameters, was measured after a period of fasting. The severity of depression was determined by the Beck Depression Inventory.
No significant difference was found between patients with MDD (723.3±233.8 ng/ml) and healthy comparison subjects (670.7±351.8 ng/ml) in mean plasma concentrations of omentin (p>0.05). There was no significant correlation between plasma omentin levels and depression severity (r=-0.147; p>0.05).
This is the first investigation of omentin levels in patients with MDD. The hypothesis that circulating omentin levels would be different in depressed patients than in healthy controls is not supported by our data.
[Show abstract][Hide abstract] ABSTRACT: Omentin is a new adipokine secreted mainly from visceral adipose tissue. Serum omentin is found to be reduced in patients with impaired glucose tolerance, type 2 diabetes mellitus, obesity and insulin resistant states. Despite the fact that pregnancy is also characterized with hyperinsulinemia, literature is lacking about data of omentin levels and its association with insulin resistance in pregnant women. We aimed to evaluate the association of omentin levels and insulin resistance in pregnant women and to compare these levels with those of non-pregnant, non-diabetic women.Uncomplicated pregnant women who admit to our outpatient clinics for routine follow-up were included in the study group. Non-pregnant women without diabetes mellitus were served as control group. Fasting glucose, insulin, omentin levels and HOMA IR were recorded. SPSS 15.0 for Windows was used for statistical analysis.There were 36 pregnant women in the study group and 37 healthy, non-pregnant women in the control group. Serum omentin and fasting glucose levels were significantly decreased and fasting insulin was significantly increased in the study group compared to control group.Omentin might be an indicator of insulin resistance in pregnant women. Larger prospective studies are needed to claim whether omentin can have a clinical use for diagnosis of gestational diabetes mellitus.
[Show abstract][Hide abstract] ABSTRACT: Unlabelled:
Hepcidin is a regulator of iron balance that is increased in obesity. It reduces the absorption of iron, reduces the transfer of iron from macrophages to the plasma and/or prevents mobilisation of stored iron. Obese patients with non-alcoholic fatty liver disease (NAFLD) demonstrate adipokine and cytokine release promoting inflammatory response. We aimed to analyse the hepcidin levels and iron metabolism in obese children with and without NAFLD and non-obese healthy controls. The study population consisted of 110 children aged 7-18 years in three groups: 50 obese patients without NAFLD, 30 obese patients with NAFLD, and 30 non-obese healthy controls. Serum hepcidin, ferritin, and iron levels, iron-binding capacity, lipid profile, and liver function tests were measured, and hepatic ultrasonography was performed in all participants. Obese patients' white blood cell counts, total cholesterol, triglyceride levels, and homeostatic model assessment of insulin resistance (HOMA-IR) were significantly higher than those of the control group. Iron-binding capacity was significantly higher in obese patients without NAFLD compared with obese patients with NAFLD (p = 0.002). Hepcidin levels were not significantly different between obese patients and the control group. However, hepcidin levels in obese patients with NAFLD were significantly higher than those in obese patients without NAFLD (p < 0.001).
Hepcidin levels were significantly higher in obese children with NAFLD than those without NAFLD. Obese children with NAFLD should receive attention regarding iron metabolism disorders. Serum hepcidin could be a marker of iron metabolism status and NAFLD in these groups of patients.

[Show abstract][Hide abstract] ABSTRACT: Ischemia-reperfusion (I-R) injury of the intestine is a significant problem because the initial damage caused by ischemia is exacerbated by reperfusion. In this study, we examined the protective effect of montelukast against I-R-induced intestinal tissue damage.
Eight-week-old male Sprague-Dawley rats were randomly divided into three treatment groups : a sham-operated group, a group receiving I-R, and a group receiving I-R plus montelukast (I-R/M). Tissue samples were evaluated and scored histologically. The blood levels of malondialdehyde (MDA), myeloperoxidase (MPO), glutathione (GSH), and cardiotrophin-1 (CT-1) were measured.
In the I-R group, the histological score and the levels of serum MDA and MPO were increased compared with those in the control group. In the I-R/M group, the histological score and serum MDA and MPO levels were significantly decreased compared with those in the I-R group. Additionally, compared with the IR group, the I-R/M group had increased serum GSH and CT-1 levels and a decreased intestinal injury score. Ileal sections from the I-R/M group showed minimal alterations, characterized by moderate lifting of the epithelial layer from the lamina propria, and few apoptotic enterocytes were observed compare with the number in the I-R group.
The findings of the present study demonstrated that montelukast can protect I-R-induced intestinal damage in rats.
