8-F2-isoprostane, thioredoxin and thioredoxin reductase levels in children with obsessive-compulsive disorder
(Taylor & Francis Ltd, 2018) Bilgic, Ayhan; Sivri, Rukiye Colak; Kilinc, Ibrahim
Purpose: Accumulating data demonstrate that oxidative stress may play a crucial role in obsessive-compulsive disorder (OCD). This study aimed to investigate the role of 8-F2-isoprostane, thioredoxin (Trx), and thioredoxin reductase (TrxR) in children with OCD.Materials and methods: Thirty-three drug-free children with OCD and 35 healthy controls were included in this study. The severity of OCD symptoms was assessed via the Children's Yale Brown Obsessive-Compulsive Scale. The severity of anxiety levels was determined through the Screen for Child Anxiety-Related Emotional Disorders. Plasma levels of 8-F2-isoprostane, Trx, and TrxR were measured using commercial enzyme-linked immunosorbent assay kits.Results: Plasma 8-F2-isoprostane, Trx, and TrxR levels did not show any significant differences between patient and control groups. There were no significant correlations between plasma levels of these antioxidants and severity of OCD.Conclusions: Findings of this study did not support the involvement of oxidative stress in the etiology of childhood OCD.
Acute and subacute effects of thymoquinone on acute methanol intoxication: An assessment based on serum TBARS and BDNF levels in rat model
(Marmara Univ, Fac Medicine, 2022) Kozak, Hasan Huseyin; Kilinc, Ibrahim; Ozkurkculer, Alpaslan
Objectives: Previous studies have shown the role of oxidative stress in methanol (MeOH) neurotoxicity. In clinical practice ethanol (EtOH) was used for the treatment of MeOH intoxication. Treatment with EtOH results in depression of the central nervous system, which may occur even at therapeutic doses. It also induces oxidative stress. Antioxidant and neuroprotective effects of thymoquinone (TQ) are known in different models of neurotoxicity. There are no studies investigating the protective effect of TQ against acute MeOH intoxication. We aimed to evaluate the effect of TQ administration on serum thiobarbituric acid reactive substances (TBARS) and Brain-Derived Neurotrophic Factor (BDNF) levels in rats with experimentally-induced MeOH intoxication. Materials and Methods: Six groups were constituted. Methotrexate (Mtx) treatment (0.3 mg/kg/day) intraperitoneally (i.p.) was given for 7 days to slow down the formate metabolism of all rats except controls in order to create a MeOH intoxication similar to that in humans. On the 8th day of the experiment, 3 g/kg MeOH was injected i.p. in MeOH, EtOH and TQ groups. Four hours after MeOH administration, 0.5 g/kg EtOH was injected i.p. in EtOH group and 30 mg/kg TQ was administered i.p. in TQ1 and TQ2 groups. In addition, a total of 5 doses of 30 mg/kg TQ was injected i.p. 24, 48, 72 and 96 hours after the first dose in TQ2 group. Saline solution was given i.p. in the other groups. Blood samples were obtained for evaluating serum TBARS and BDNF levels. Results: The highest TBARS level was found in MeOH+MTx group and this increase was statistically significant as compared to control and Mtx groups (p<0.001) . A statistically significant reduction was detected in serum TBARS levels in MeOH+Mtx+EtOH, MeOH+Mtx+TQ1 and MeOH+Mtx+TQ2 groups (p<0.001). Maximum serum BDNF level elevation was found in MeOH+Mtx group and this increase was statistically significant as compared to control and Mtx groups (p<0.001). Serum BDNF levels were higher in MeOH+Mtx+EtOH, MeOH+Mtx+TQ1 and MeOH+Mtx+TQ2 groups and the difference was statistically significant (p<0.001). Conclusions: Thymoquinone could suppress proinflammation and lipid peroxidation in MeOH intoxication, lead to rapid toxicity adaptation, and play the role of neuroprotection more effectively than EtOH. These results may suggest that TQ could be used as an alternative treatment option in MeOH intoxication.
Alpha-Amanitin Poisoning, Nephrotoxicity and Oxidative Stress: An Experimental Mouse Model
(Kowsar Publ, 2015) Ergin, Mehmet; Dundar, Zerrin Defne; Kilinc, Ibrahim; Colak, Tamer; Oltulu, Pembe; Girisgin, Abdullah Sadik
Background: Alpha-amanitin (alpha-AMA) plays a major role in Amanita phalloides poisoning, showing toxic effects on multi-organs, particularly on the liver and kidneys. Studies have shown a relationship between alpha-AMA-related injuries and reactive oxygen species. Objectives: We aimed to investigate whether there is renal injury and its relationship with oxidative stress after intraperitoneal injection of alpha-AMA in mice experimental poisoning models. Materials and Methods: There were 37 male BALB/c laboratory mice treated with alpha-AMA, according to the study groups: control group (n = 7); low dose (0.2 mg/kg) (n = 10); moderate dose (0.6 mg/kg) (n = 10), and high dose (1 mg/kg) (n = 10). The sample size was detected according to the ethical committee's decision as well as similar studies in the literature. After a 48-hour follow-up period, all the subjects were sacrificed for pathological and biochemical assays. The study was held in Turkey. Results: alpha-AMA poisoning in mice results in inflammatory changes and necrosis in renal structures. There were statistically significant differences between the study groups regarding measured levels of catalase, superoxide dismutase, glutathione peroxidase, total antioxidant status (TAS), total oxidant status (TOS) and malonyl dialdehyde in renal homogenates of mice (P < 0.001, P < 0.001, P < 0.001, P < 0.001, P < 0.001, and P = 0.001, respectively). The TOS and TAS measurements helped to eliminate cumbersome analysis of diverse oxidant and antioxidant molecules. The TOS levels in renal homogenate of mice were significantly higher in all the intoxication groups compared to the control group (5.73, 7.02, 7.77, and 9.65 mmol trolox eq/g protein and P = 0.002, P = 0.001, and P = 0.001, respectively). The TAS levels in moderate and high-dose groups were significantly lower than all the other groups treated with alpha-AMA (0.130, 0.152, 0.065, and 0.087 mmol trolox eq/g protein and P = 0.031, P = 0.001, and P = 0.001, respectively). Conclusions: Our results indicated that alpha-AMA poisoning in mice led to inflammatory changes and necrosis in renal structures. Biochemical analysis showed a shift in the oxidative/anti-oxidative balance towards the oxidative status.

(Turkish Assoc Trauma Emergency Surgery, 2020) Toguslu, Gokhan; Erdi, Mehmet Fatih; Arac, Densel; Keskin, Fatih; Kilinc, Ibrahim; Cuce, Gokhan
BACKGROUND: Adalimumab (ADA), which is a new-generation recombinant human monoclonal antibody for tumor necrosis factor a (TNF alpha), has strong anti-inflammatory effects. The role of enhanced inflammation is well established for the development and progression of cerebral vasospasm. Investigated in the present study is the probable ameliorating and neuroprotective effects of ADA in rabbits using a cerebral vasospasm model with biochemical and histopathological methods. METHODS: Thirty male New-Zealand white rabbits were randomly divided into control, subarachnoid hemorrhage (SAH) only and SAH plus ADA treatment groups. SAH was established as a single cisterna magna autologous arterial blood injection. ADA treatment was started just after intracisternal blood injection and continued for 72 hours once a day. The animals were sacrificed 72 hours after the induction of SAH, serum and brainstem tissue obtained for investigations. RESULTS: Brainstem tissue and plasma levels of tumor necrosis factor-alpha and Interleukin-1 beta, brainstem tissue Matrix metalloproteinase-9 levels increased after SAH and partly decreased after treatment. Plasma levels of brain-derived neurotrophic factor decreased after SAH and partly restored after treatment. ADA treatment significantly increased the mean cross-sectional area of the vasospastic basilar arteries, reduced the basilar artery wall thickness and also ameliorates enhanced endothelial apoptosis. CONCLUSION: Findings obtained in this study suggest that ADA is an effective neuroprotective agent for ameliorating cerebral vasospasm in experimental rabbit vasospasm.

(Elsevier France-Editions Scientifiques Medicales Elsevier, 2017) Ozer, Erdem Kamil; Goktas, Mustafa Tugrul; Kilinc, Ibrahim; Bariskaner, Hulagu; Ugurluoglu, Ceyhan; Iskit, Alper Bektas
Background: The cyclooxygenase (COX)-2 overexpression is associated with vascular injury and multiple organ failure in sepsis. However, constitutive COX-1 and basal COX-2 expressions have physiological effects. We aimed to investigate the effects of partial and selective COX-2 inhibition without affecting constitutive COX-1 and basal COX-2 activities by celecoxib on mesenteric artery blood flow (MABF), vascular reactivity, oxidative and inflammatory injuries, and survival in septic rats accomplished by cecal ligation and puncture (CLP). Methods: Wistar rats were allocated into Sham, CLP, Sham + celecoxib, CLP + celecoxib subgroups. 2 h after Sham and CLP operations, celecoxib (0.5 mg/kg) or vehicle (saline; 1 mL/kg) was administered orally to rats. 18 h after drug administrations, MABF and responses of isolated aortic rings to phenylephrine were measured. Tissue samples were obtained for biochemical and histopathological examinations. Furthermore, survival rate was monitored throughout 96 h. Results: Celecoxib ameliorated mesenteric hypoperfusion and partially improved aortic dysfunction induced by CLP. Survival rate was % 0 at 49th h in CLP group, but in CLP + celecoxib group it was 42.8% at the end of 96 h. Serum AST, ALT, LDH, BUN, Cr and inflammatory cytokine (tumor necrosis factor-alpha, interleukin-1 beta and interleukin-6) levels were increased in CLP group that were prevented by celecoxib. The decreases in liver and spleen glutathione levels and the increases in liver, lung, spleen and kidney malondialdehyde levels in CLP group were blocked by celecoxib. The histopathological protective effects of celecoxib on organ injury due to CLP were also observed. Conclusions: Celecoxib has protective effects on sepsis due to its preservative effects on mesenteric perfusion, aortic function and its anti-inflammatory and antioxidative effects.

Claudin-5, occludin, zonulin and tricellulin levels of children with attention-deficit/hyperactivity disorder
(Elsevier Espana Slu, 2024) Ferahkaya, Hursit; Akca, Omer Faruk; Baysal, Tamer; Kilinc, Ibrahim
Background and objectives: Accumulating studies have pointed out that gut-blood and blood -brain barrier dysfunctions due to the alterations in permeability may play a role in the patho-physiology of neurodevelopmental disorders. Tight junctions are crucial components of these barriers and some peptides including claudin-5, occludin, zonulin and tricellulin are important components of these structures. This study aimed to investigate the relationship between these molecules and attention deficit hyperactivity disorder (ADHD) in children and adolescents.Methods: A total of 57 children with ADHD and 60 controls aged between 6 and 12 years were included in the study. The severity of ADHD symptoms was assessed through a parent-rated questionnaire, and Conner's Continuous Performance Test was administered to the study group. Serum levels of biochemical variables were measured using enzyme-linked immunosorbent assay kits. Biochemical parameter levels and scale scores were compared using Mann-Whitney U or Student's t tests. In addition, a multivariate analysis of covariance (MANCOVA) and a one-way analysis of covariance (ANCOVA) was performed on the outcome variables. Finally, a hierarchical regression model was conducted on the study group.Results: Serum claudin-5 and tricellulin levels were significantly lower in the ADHD group compared to the control group. The difference between the groups in terms of serum claudin-5 and tricellulin levels remained significant after controlling for confounding factors such as age, gender and autistic characteristics. There was no significant difference between the groups in terms of serum zonulin and occludin levels.Conclusion: These results reveal that claudin-5 and tricellulin levels vary in patients with ADHD. Alterations in these peptides may affect the brain by leading to a dysregulation in intestinal or blood-brain barrier permeability. The causal relationship between these peptides and ADHD requires further investigation.(c) 2023 Sociedad Espanola de Psiquiatna y Salud Mental. Published by Elsevier Espana, S.L.U.

Coenzyme Q10 improves the survival, mesenteric perfusion, organs and vessel functions in septic rats
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2017) Ozer, Erdem Kamil; Goktas, Mustafa Tugrul; Kilinc, Ibrahim; Pehlivan, Sultan; Bariskaner, Hulagu; Ugurluoglu, Ceyhan; Iskit, Alper Bektas
Background: Coenzyme Q10 (CoQ10) is a naturally occurring, lipid-soluble antioxidant and an essential electron carrier in the mitochondrial respiratory chain. In sepsis, CoQ10 deficiency induced by mitochondrial failure can lead to hypoxia, hypoperfusion, oxidative organ damage and finally death. We aimed to investigate the effects of CoQ10 on survival, mesenteric artery blood flow (MABF), vascular reactivity, oxidative and inflammatory injuries in cecal ligation and puncture (CLP)-induced sepsis. Methods: Wistar rats were divided into Sham, CLP, Sham + CoQ10, CLP + CoQ10 subgroups. CoQ10 (10 mg/kg/day) or vehicle (olive oil; 1 mL/kg/day) was intraperitoneally injected for 15 days. At 16th day, Sham or CLP operation was performed. 20 h after the operations, MABF and phenylephrine responses of isolated aortic rings were measured. Tissue samples were obtained for histopathological and biochemical evaluations. Furthermore, survival rates were monitored throughout 96 h. Results: CoQ10 prevented mesenteric hypoperfusion and aortic dysfunction induced by CLP. Survival rate was % 0 at 46th h in CLP group, but in CLP + CoQ10 group it was 37.5% at the end of 96 h. CLP-induced elevations of serum AST, ALT, LDH, BUN, Cr and inflammatory cytokine (tumor necrosis factor-alpha, interleukin-1 beta and interleukin-6) levels were blocked by CoQ10. CoQ10 restored the increased liver, lung, spleen and kidney malondialdehyde levels and as well as reduced liver and spleen glutathione levels. The protective effects of CoQ10 on multiple organ damage were also observed histopathologically. Conclusions: CoQ10 showed protective effects in sepsis due to its preservative effects on mesenteric perfusion, aortic function and also its anti-inflammatory and antioxidative effects.

A cross-sectional study to assess the association between major depression and inflammatory markers in patients with acute ischemic stroke
(Wolters Kluwer Medknow Publications, 2019) Kozak, Hasan Huseyin; Uguz, Faruk; Kilinc, Ibrahim; Uca, Ali Ulvi; Tokgoz, Osman Serhat; Guney, Figen; Ozer, Nejla
Background: Increased interest in the relationship between affective disorder and long-term health consequences has generated recent examinations of depression and stroke. Observations suggest that depressive disorder is associated with abnormal physiological and immunological responses and a resultant increase in inflammatory markers. Given the high prevalence of stroke and associated costs for the community, it is important to understand the mechanisms that may impact on the outcome to achieve the best possible prognosis. Aims: The view that inflammatory factors contribute to depression is predicated on findings that circulating cytokines and other inflammatory factors are increased in depressed patients. Therefore, it has been hypothesized that inflammation could be one of the mechanisms by which depression increases risk for ischemic stroke. Our aim was to determine whether there is any relationship between major depression and tumor necrosis factor-alpha (TNF-alpha), interleukin-1 beta (IL-1 beta), IL-18, brain-derived neurotrophic factor (BDNF), and neuron-specific enolase (NSE) in patients with acute ischemic stroke (AIS). Study Design: This was as a cross-sectional design. Materials and Methods: This study has a cross-sectional design, and it was conducted in Necmettin Erbakan University, the Meram Faculty of Medicine in Konya, Turkey, between 2014 and 2015. Fifty-three AIS patients admitted to the hospital within the first 24 h after stroke onset were recruited. Major depression was ascertained by means of the structured clinical interview for the diagnostic and statistical manual of mental disorders, Fourth Edition/Clinical Version. The enzyme-linked immunosorbent assay was used to measure the serum levels of TNF-alpha, IL-1 beta, IL-18, BDNF, and NSE at admission. Results: A total of 53 patients with a mean age of 65.9 years were recruited. Of these patients, 17 (32.1%) had major depression. Depressive and nondepressive patients had similar demographical and clinical features. There was no significant statistical difference between depressive and nondepressive patients with AIS with respect to levels of TNF-alpha, IL-1 beta, IL-18, BDNF, and NSE. Conclusion: This study suggests that in patients who have experienced AIS, there is no significant relationship between major depression and basal proinflammatory cytokines (TNF-alpha, IL-1 beta, IL-18), BDNF, and NSE.
Cytokine, chemokine and BDNF levels in medication-free pediatric patients with obsessive-compulsive disorder
(Springer, 2018) Sivri, Rukiye Colak; Bilgic, Ayhan; Kilinc, Ibrahim
The aim of this study was to investigate whether the serum levels of IL-12, IL-17, TGF beta, TNF-alpha, sTNFR1, sTNFR2, IL-1 beta, CCL3, CCL24, CXCL8, and BDNF are associated with obsessive-compulsive disorder (OCD) in medication-free children. A total of 44 (22 boys/22 girls) medication-free children with OCD and 40 (23 boys/17 girls) healthy controls were included in this study. The severity of the OCD symptoms were assessed by the Children's Yale-Brown Obsessive-Compulsive Scale and the Maudsley Obsessive-Compulsive Inventory. The Children's Depression Inventory and the Screen for Child Anxiety-Related Emotional Disorders were applied to the children in order to determine depression and anxiety levels. IL-17, IL-12, TGF beta, TNF-alpha, sTNFR1, sTNFR2, IL-1 beta, CCL3, CCL24, CXCL8, and BDNF levels were measured by enzyme-linked immunosorbent assay. Multivariate analysis of covariance (MANCOVA) revealed a significant main effect on both groups for the levels of serum cytokine, chemokine, and BDNF, an effect that was independent of severities of depression and anxiety [Pillai's Trace V = 0.371, F (11, 70) = 3.756, p < 0.001, hp(2) = 0.187]. Analysis of covariance (ANCOVA) indicated that serum TNF-alpha levels were significantly higher in the OCD group than in the control group (p < 0.001). In contrast, serum IL-12 levels were significantly lower in the OCD group than in the control group (p = 0.014). These findings suggest that TNF-alpha and IL-12 may play a role in the pathophysiology of OCD in children. The causal relationship between these proinflammatory cytokines and pediatric OCD requires further investigation.
Decreased plasma intercellular adhesion molecule-3 levels are associated with obsessive compulsive disorder in medication-free children
(Elsevier, 2020) Bilgic, Ayhan; Ileri, Betul Akbas; Kilinc, Ibrahim; Akca, Omer Faruk
The objective of this study was to evaluate whether the plasma levels of soluble intercellular adhesion molecule-1 (sICAM-1), intercellular adhesion molecule-3 (sICAM-3), vascular cell adhesion molecule-1 (sVCAM-1), and/or platelet endothelial cell adhesion molecule-1 (sPECAM-1) were associated with obsessive compulsive disorder (OCD) in childhood. A total of 42 (25 boys, 17 girls) medication-free children with OCD and 38 (18 boys, 20 girls) healthy controls aged 8-18 years were included in the study. The severity of the OCD symptoms was assessed using the Children's Yale-Brown Obsessive Compulsive Scale. The Children's Depression Inventory and the Screen for Child Anxiety-Related Emotional Disorders were used to measure the children's depression and anxiety levels. The sICAM-1, sICAM-3, sVCAM-1, and sPECAM-1 concentrations were measured using an enzyme-linked immunosorbent assay. A multivariate analysis of covariance revealed a significant main effect on both groups in terms of the concentrations of plasma adhesion molecules, which was independent of the severities of depression and anxiety, body mass index percentile, age, and sex. An analysis of covariance showed that plasma sICAM-3 concentrations were significantly lower in the OCD group than in the control group. These data suggest that sICAM-3 may play a role in the etiopathogenesis of OCD in children.
Delirium in patients with acute ischemic stroke admitted to the non-intensive stroke unit: Incidence and association between clinical features and inflammatory markers
(Termedia Publishing House Ltd, 2017) Kozak, Hasan Huseyin; Uguz, Faruk; Kilinc, Ibrahim; Uca, Ali Ulvi; Tokgoz, Osman Serhat; Akpinar, Zehra; Ozer, Nejla
Background: Stroke patients with development of delirium have unfavorable outcomes, higher mortality, longer hospitalizations, and a greater degree of dependence after discharge. Studies suggest that delirium is associated with abnormal immunological responses and a resultant increase in inflammatory markers. Objective: Our aim was to determine whether there is an entity relationship between delirium, inflammation and acute ischemic stroke (AIS). Methods: Sixty AIS patients admitted to the hospital were consecutively recruited. Delirium was diagnosed with the clinical assessment according to the Statistical Manual of Mental Disorders, Fifth Edition (DSM-V) criteria. Enzyme-linked immunosorbent assay (ELISA) was used to measure serum levels of Interleukin-1 beta (IL-1 beta), Interleukin 18 (IL-18), Tumor Necrosis Factor-alpha (TNF-alpha), Brain-Derived Neurotrophic Factor (BDNF), and Neuron Specific Enolase (NSE) at admission. Results: Eleven (18.3%) of 60 patients were diagnosed with delirium, and the majority (n = 8, 72.7%) was the hypoactive type. Delirious and non-delirious patients had similar demographic and clinical features. Delirious patients had significantly higher lengths of hospital stay, National Institutes of Health Stroke Scale (NIHSS) at admission and discharge compared to non-delirious patients. In addition, there was no significant statistical difference between delirious and non-delirious patients with AIS in respect of levels of TNF-alpha, IL-1 beta, IL-18, BDNF and NSE. This study suggests that delirium is not scarce in patients with AIS admitted to the non-intensive stroke unit, and that delirium developing after AIS seems not to be associated with serum TNF-alpha, IL-1 beta, IL-18, BDNF and NSE but is associated with length of hospital stay and stroke severity.

(Galenos Publ House, 2017) Ozer, Muhammet Rasit; Ergin, Mehmet; Kilinc, Ibrahim; Dundar, Zerrin Defne; Ozer, Nejla; Onal, Mehmet Akif; Girisgin, Abdullah Sadik
Aim: The aim was to evaluate the levels of serum pentraxin-3 (PTX-3) and neutrophil gelatinase-associated lipocalin (NGAL) and the efficiency of making a diagnosis and to estimate the prognosis in patients with chest pain. Materials and Methods: The study was conducted in the Necmettin Erbakan University Meram Medicine School Emergency Department. Patients who had chest pain and met the inclusion criteria were accepted. They were divided into the following groups: acute coronary syndrome (ACS), a diagnosis other than ACS (non-ACS), and control. The patients in theACS and non-ACS groups were divided into five sub-group - groups: ST Elevated Myocardial Infarction (STEMI) Non-ST Elevated Myocardial Infarction (NSTEMI), Unstable Angina Pectoris (USAP), stable angina, and pulmonary embolus. For all patients, serum PTX-3, serum NGAL, troponin I, and creatine kinase-MB fraction (CK-MB) levels were measured. Results: There were 199 patients in the ACS and non-ACS groups and 30 patientsin the control group. There was no significant difference among the study groups in terms of age and PTX-3 and NGAL levels. When comparing survival and non-survival in terms of in-hospital death, CK-MB and troponin I levels were significantly higher in the ACS and non-ACS groups than in the control groups, whereas there was no significant difference in terms of PTX-3 and NGAL levels. Conclusion: The results of our study demonstrated that PTX-3 and NGAL are not effective biomarkers in the differential diagnosis and the determination of in-hospital mortality in ACS. However, the limitations of the study should be considered. The results confirmed that CK-MB and Troponin I can be safely used in the differential diagnosis and the prediction of mortality.
Does Estradiol Level in Platelet-Rich Plasma Improve Efficacy of Androgenic Alopecia Treatment?
(Oxford Univ Press Inc, 2020) Ince, Bilsev; Kendir, Munur Selcuk; Kilinc, Ibrahim; Avunduk, Mustafa Cihat; Dadaci, Mehmet; Savaci, Nedim
Background: Although some studies in the literature report that autologous and homologous platelet-rich plasma (PRP) can be employed in the treatment of androgenic alopecia (AGA), no study, to the authors' knowledge, has examined the estrogen concentration of prepared PRP. Objectives: The authors aimed to determine the presence of estrogen in PRP and to investigate the effect of estrogen concentration of PRP on AGA treatment. Methods: Between 2017 and 2018, 30 male patients with hair loss complaints were included in this prospective study. Autologous PRP was injected in patients in Group 1. Homologous PRP with high estrogen levels was injected in the patients in Group 2. PRP was injected in both groups 4 times at 0,1, 3, and 6 months. The obtained photographs were evaluated and hair densities of each patient at controls were calculated. Results: The mean estrogen level measured in PRP was statistically significantly higher in Group 2. In both groups, the increase in hair density was observed from the first month, but this increase was statistically significantly higher in all controls in Group 2. In Group 2, there was a statistically significant increase in the 1st and 3rd months compared with the previous control, but there was no difference between the 6th and 12th months and the 3rd month. Conclusions: Increased hair density is greater and earlier in the group receiving estrogen-rich PRP than in the group utilizing autologous PRP. The authors think that estrogen-rich PRP may be employed in the treatment of AGA in the presence of an appropriate donor.

(Tubitak Scientific & Technological Research Council Turkey, 2018) Ince, Bilsev; Dadaci, Mehmet; Kilinc, Ibrahim; Oltulu, Pembe; Yarar, Serhat; Uyar, Mehmet
Background/aim: The aim of this study was to determine the specific component of Rosmarinus officinalis (RO) responsible for increased flap survival and how RO displays its efficacy. Materials and methods: Rectangular random-pattern flaps were elevated from the back of each rat. Group I was the control group. In group II 0.1 mL of cineole, in group III 0.1 mL of alpha-pinene, in group IV 0.1 mL of camphor, in group V 0.1 mL each of alpha-pinene and cineole, in group VI 0.1 mL each of alpha-pinene and camphor, in group VII 0.1 mL each of cineole and camphor, and in group VIII, 0.1 mL each of alpha-pinene, cineole, and camphor was orally administered once a day before surgery. The luminal area of the largest blood vessel in the proximal flap was measured. Interleukin-1, tumor necrosis factor alpha, thiobarbituric acid reactive substances, and vascular endothelial growth factor values were measured. Results: The mean percentage of the viable surface area was significantly greater in groups VIII, III, and V. The mean percentage of vessel diameter was significantly greater in groups V, VIII, and VII. Conclusion: We suggest that alpha-pinene and cineole were the components of RO that were responsible for increased flap survival. The most effective of feature of RO was the antiinflammatory effects.

(Springernature, 2022) Fidan, Esra; Gormus, Z. Isik Solak; Kilinc, Ibrahim; Iyisoy, Mehmet Sinan; Gormus, Niyazi
The objective of this study is to determine the synergistic effects of an antioxidant ion Mg+2, combined with selective serotonin reuptake inhibitor sertraline, in treatment or prevention of major depression and regulation of inotropic effect in the early postoperative period. Adult male 40 Wistar albino rats were randomly divided into 6 groups. Three to 4-mm long atrium strips were placed in organ bath, tension was adjusted to 2 g. Isometric contractions were induced with 10(-3) M adrenaline. Group 1 was the control group, cumulative sertraline was given to group 2, cumulative MgSO4 to group 3, combined cumulative sertraline and MgSO4 to group 4, intraperitoneal sertraline injection for 29 days to group 5, and intraperitoneal MgSO4 injection for 14 days to group 6. Changes in weight, tensions, bleeding/clotting time, and biochemical findings were evaluated statistically. Isometric tension relationship between groups 1 and 3 was statistically significant after 4 mmol/L MgSO4 (p < 0.05). A rapid inhibition of contraction was observed in group 4. Inhibition of spontaneous contractions of groups 5 and 6 was found to be statistically significant at close values, p < 0.05. When blood clotting times were compared, a statistically marked decrease was found in group 6, p < 0.05. Compared to control group, there was a significant decrease in blood lipids in group 4. While LDH and CK-MB increased from plasma enzymes in groups 5 and 6, no significant change was observed in NT-proBNP. Combined treatment of high dose MgSO4 with antidepressants for pre or post-operative depression may cause fatal risks. Shortening clotting time may increase the risk of embolism and stroke. In order to reduce the risk of post-operative depression preoperatively, care should be taken when using magnesium combined with antidepressants and more studies are needed to be considered.
The effects of smoking on vascular endothelial growth factor and inflammation markers: A case-control study
(Wiley, 2018) Ugur, Merve Guzeldulger; Kutlu, Ruhusen; Kilinc, Ibrahim
Background and AimsChronic obstructive pulmonary disease (COPD) is a type of obstructive lung disease characterized by long-term poor airflow. Tobacco smoking is the most common cause of COPD. In this study, we aimed to assess the vascular endothelial growth factor (VEGF) and inflammation markers on smokers and non-smoking individuals. MethodsOur study was a case-control study and 175 individuals who want to give up smoking constituted the case group. As a control group, 175 individuals who never smoked. ResultsThe mean age of 350 participants was 35.8313.11 years. Educational status of the non-smokers was significantly higher than that of the smoking group (P<.001). When smoking and non-smoking groups were compared in terms of VEGF and interleukin-6 (IL-6), it was found that these values were statistically higher in smokers than non-smokers (P<.001). The levels of IL-10 were found to be higher in non-smokers than in smokers (P<.001). Although a moderate positive correlation was found between VEGF and IL-6 levels (r=.486, P<.001), there was a weak negative correlation between VEGF and IL-10 (r=-.210, P<.001). A weak negative correlation was found between IL-6 and IL-10 (r=-.185, P<.001). ConclusionsIn our study, IL-6 inflammatory marker and VEGF levels were found to be high and IL-10 anti-inflammatory marker was discovered to be low in smokers. For this reason, raising awareness in the society about the harms of smoking and encouraging people to give it up have become more challenging to counteract the inflammatory effects of smoking in human body and to prevent many smoking-related diseases.

Objective: The current study aimed to measure the levels of vitamin 25(OH)D in pregnant women and in the umbilical cord blood of newborns and to evaluate the association of vitamin D levels with birth parameters.Methods: This cross-sectional analytic investigation was performed in 100 pregnant women at term and in 100 newborns born to these mothers. Plasma vitamin D level was measured and birth parameters of the babies were recorded.Results: Mean vitamin D levels in pregnant women and cord blood were 11.396.24ng/ml and 8.00 +/- 4.95ng/ml, respectively. Vitamin D levels were found to be higher in the women who had received vitamin D support during pregnancy (p<.001). Height (p=.004), head circumference (p=.003), and chest circumference (p=.005) of newborns born to mothers who had received vitamin D support were higher compared to non-receivers. Maternal vitamin D deficiency (<10ng/ml) and insufficiency (10-30ng/ml) was detected in 53.0% and 47.0% of the cases, respectively. None of the women had sufficient levels of vitamin D.Conclusions: This study established that vitamin D levels were low in maternal and cord blood in spite of the administration program of Ministry of Health in pregnant women. The importance of vitamin D supplementation should be explained to the pregnant women in each visit.

This study aimed to investigate the role of leptin, ghrelin, neuropeptide Y, and nesfatin-1 in young children with autism spectrum disorder (ASD). A total of 44 children with ASD and 44 healthy controls aged 18-60 months were included. Plasma levels of hormones were measured using commercial enzyme-linked immunosorbent assay kits. Plasma leptin and ghrelin levels were significantly higher in the ASD group than in the control group. However, no significant difference for plasma neuropeptide Y and nesfatin-1 levels was detected between the groups. No relation was found between the severity of ASD symptoms, severity of eating problems, and plasma levels of hormones. Leptin and ghrelin may play a potential role in the pathogenesis of ASD.
