Abstract
Migraine is a common and disabling primary headache disorder and inflammation is a proposed factor in the complex ethiology of the disease. Gasdermin D (GSDMD) is a membrane pore-forming protein acting through the caspase system. End result is cell death caused by leakage of intracellular components to extracellular space which also results in inflammation. Stemming from this knowledge, the potential role of GSDMD in migraine was investigated in this prospective study. This prospective study was conducted between September 2022 to April 2023. 47 patients with migraine were designated as the patient group, whereas 47 healthy volunteers were designated as the control group. Serum GSDMD levels of both groups were compared, with an additional comparison between migraine patients during symptom-free and attack periods. Migraine related characteristics of the patients were also included in the study. Median GSDMD levels of the patient and control group did not reveal a significant difference. Nausea, vomiting and severity of headache were found to be correlated with GSDMD levels in migraine patients. Patients with nausea revealed a higher GSDMD level compared to patients without nausea during both symptom-free and attack periods (p = 0.021 and p = 0.01, respectively). Nausea was correlated to higher GSDMD levels in the patient population during symptom-free period (p = 0.030). The severity of pain was positively correlated with GSDMD levels during the attack period (p < 0.001). Gasdermin family and GSDMD in particular are promising prospects for therapy in a wide spectrum of disorders. Gasdermin proteins are candidates to be the focus for future studies both related to pathogenesis and drug therapy in migraine and varying inflammatory-driven clinical pictures.

Abstract
Crohn's disease is a chronic inflammatory disease of the gastrointestinal tract. Immunosuppressive therapy is the main treatment modality in Crohn's disease. Herpes zoster (HZ), caused by Varicella-zoster virus, is a relatively common albeit burdensome clinical picture mainly affecting adult population with immunosuppressive status. In this paper, we aimed to report a Crohn's disease patient with HZ to raise awareness on vaccination. There are commercially available vaccines that are shown to be safe and effective against HZ reactivation. Crohn's disease patients should be evaluated and informed about preventive options against HZ to prevent unwanted HZ-related complications.

Abstract
OBJECTIVES In this study, we presented neuroradiologic findings and diagnoses of neurologic complications in a series of heart transplant recipients. MATERIALS AND METHODS A retrospective review was conducted at Başkent University Hospital. We searched the hospital and radiology databases and identified 109 heart transplant recipients. Thirty-one of these recipients had neuroradiologic evaluations secondary to presentation of neurologic symptoms after heart transplant, with 18 patients evaluated with computed tomography and 22 patients evaluated with magnetic resonance imaging (overlap of imaging-defined groups occurred in 9 recipients). Computed tomography and magnetic resonance imaging studies were retrieved from the Picture Archiving and Communication System, with each type of imaging retrospectively evaluated on consensus by 2 radiologists. RESULTS Radiopathologic findings related to symptoms were detected in 12 of the 31 study patients. The most common abnormality was posterior reversible leukoencephalopathy syndrome (5 patients, 4.6%). The other abnormalities were ischemic stroke (3 patients, 2.8%), hemorrhagic stroke (1 patient, 0.9%), intracranial abscess (2 patients, 1.8%), and intracranial dissemination of sinusoidal fungal infection and related hemorrhagic infarct (1 patient, 0.9%). The other 19 heart transplant recipients who underwent computed tomography and/or magnetic resonance imaging for neurologic complaints showed no neuroradiologic findings related to neurologic symptoms. CONCLUSIONS Posterior reversible leukoencephalopathy syndrome and ischemic stroke were the most common neurologic complications in our heart transplant recipients. The other complications were hemorrhagic stroke, intracranial abscess, and intracranial dissemination of sinusoidal fungal infection. Neurologic complications are common in heart transplant recipients and should be identified promptly for early treatment. For the recognition of these complications, computed tomography should be performed for initial evaluation to rule out edema or hemorrhage. However, in the presence of serious neurologic symptoms that cannot be explained by computed tomography, magnetic resonance imaging should be indicated.

Abstract
Aim To compare the relationship between white matter hyperintensities (WMH) on brain magnetic resonance imaging and retinal nerve fiber layer (RNFL), choroid, and ganglion cell layer (GCL) thicknesses in migraine patients and healthy subjects. We also assessed the role of cerebral hypoperfusion in the formation of these WMH lesions. Methods We enrolled 35 migraine patients without WMH, 37 migraine patients with WMH, and 37 healthy control subjects examined in the Neurology outpatient clinic of our tertiary center from May to December 2015. RFNL, choroid, and GCL thicknesses were measured by optic coherence tomography. Results There were no differences in the RFNL, choroid, or GCL thicknesses between migraine patients with and without WMH ( p > 0.05). Choroid layer thicknesses were significantly lower in migraine patients compared to control subjects ( p < 0.05), while there were no differences in RFNL and GCL thicknesses ( p > 0.05). Conclusions The ‘only cerebral hypoperfusion’ theory was insufficient to explain the pathophysiology of WMH lesions in migraine patients. In addition, the thinning of the choroid thicknesses in migraine patients suggests a potential causative role for cerebral hypoperfusion and decreased perfusion pressure of the choroid layer.

Abstract
The aim of this study was to evaluate the effects of N-acetylcysteine (NAC) and desferoxamine (DFO) administered alone or in combination together in rats with doxorubicin (DOX)-induced nephrotic syndrome, by monitoring oxidative stress parameters and trace elements in renal tissue and erythrocytes. Fifty-four male Sprague-Dawley rats were included the study. Equal volume of isotonic saline was injected to control rats. After DOX administration, the animals were divided into four experimental groups: (a) rats given only DOX; (b) rats treated with NAC; (c) rats treated with DFO; (d) rats treated with NAC plus DFO. The combination of N-acetylcysteine and DFO has no beneficial effect on reducing proteinuria in experimentally nephrotic rats, although both of these agents ameliorate the condition when administered separately. It seems likely that detrimental effects of NAC plus DFO could be secondary to its effects on erythrocyte selenium levels demonstrated here. Consequently, the results may propose caution to the use of antioxidant therapeutic strategies such as NAC plus DFO against nephropathy.

Abstract
OBJECTIVE Determining the severity of sarcoidosis is based on the clinical and radiological findings of the disease and the changes in pulmonary function test results. On the other hand; studies are ongoing for objective and easy markers in this respect. Neutrophil/lymphocyte ratio (NLR) is shown as a good prognostic marker for inflammation due to tissue damage in recent clinical trials. In this study, we aimed to identify the possible relationship between NLR and radiological extent of sarcoidosis. PATIENTS AND METHODS Data of 122 patients included in the study were evaluated retrospectively in terms of age, gender, complete blood count parameters, erythrocyte sedimentation rate (ESR) and radiological findings at the time of diagnosis. RESULTS Mean NLR and ESR were significantly different between radiological stages according to chest radiography and also total HRCT score (THS) groups according to parenchymal involvement in thorax tomography (p <0.05). Mean NLR was found to be 1.28 in stage 0, 1.65 in stage 1, 2.88 in stage 2,5.47 in stage 3 and 8.48 in stage 4; 1.63 in THS group 1, 2.01 in group 2, 3.47 in group 3 and 5.46 in group 4. There were statistically significant positive correlations between NLR and WBC, NLR and THS, NLR and ESR, THS and ESR, ESR and platelet, WBC and #neutrophil, WBC and #lymphocyte. CONCLUSIONS Our findings suggest that NLR might be used as a prognostic marker in pulmonary sarcoidosis.

Abstract
INTRODUCTION Our aim was to determine the efficacy of trimetazidine on experimental sepsis rat model. MATERIAL AND METHODS Sixty rats were randomized into three groups. In Group 1, sepsis was induced. In Group 2, sepsis was induced and as a therapeutic agent trimetazidine was given. In Group 3, rats were sham operated. Serum interleukin-1 beta (IL-1ß), tumor necrosis factor alfa (TNF-α), superoxide dismutase (SOD), glutathion peroxidase (GSH-Px) and malondialdehyde (MDA) levels were determined in all groups. RESULTS In Group 2, serum GSH-Px and SOD levels were statistically significantly higher than in Group 1 (p< 0.05) and serum MDA levels were statistically significantly lower than in group 1 (p < 0.05). Trimetazidine also significantly decreased the levels of IL-1ß and TNF-a which are the proinflammatory cytokines (p < 0.05). CONCLUSION Trimetazidine treatment significantly improved inflammation, oxidative stress and membrane destruction in LPS-induced sepsis. As the proinflammatory cytokines are supposed to play a primary role in the pathogenesis of sepsis, we assumed that the trimetazidine treatment would give new insights into the treatment of sepsis (Tab. 1, Fig. 5, Ref. 29).

Abstract
INTRODUCTION This study was conducted to evaluate the oxidant/antioxidant balance (oxidative stress status) and plasma essential trace element levels in patients with bronchial asthma or allergic rhinitis. METHODS A total of 94 individuals consisting of 19 allergic asthmatics; 17 non-allergic asthmatics; 22 patients with allergic rhinitis; and 36 healthy control people were enrolled into this study. Superoxide dismutase (CuZnSOD) and glutathione peroxidase (GSH-Px) activity as antioxidant defence mechanism parameters, along with malondialdehyde (MDA) as a marker of lipid peroxidation, were determined in erythrocytes of patient groups and controls. Plasma copper and zinc levels were also determined in all groups. RESULTS CuZnSOD activity was significantly lower in all groups of patients (p<0.001 for allergic asthmatics, p=0.008 for allergic rhinitis patients, and p<0.001 for non-allergic asthmatics) when compared to those of controls. Erythrocyte GSH-Px enzyme activity was not different when compared to that of the control group. Similarly, the patient groups had no difference from those of the controls with respect to erythrocyte MDA levels. While plasma Cu levels in all asthmatic patients were not different from those of the controls, allergic rhinitis patients had significantly elevated (p<0.001) Cu levels compared to those of the controls. No statistically significant difference was established between patient groups and controls with respect to plasma zinc levels. CONCLUSION While defective CuZnSOD activity observed in all patients groups was expected to cause an increase in lipid peroxidation indicated by high MDA levels in these patients groups, the fact that MDA levels were not different from those of controls in all patient groups indicates that other components of anti-oxidant defence system preserve their functions in these patients. On the other hand, statistically significant difference between all patients groups and controls with respect to trace elements was only observed in allergic rhinitis patients who had higher levels of Cu than those of controls.

Abstract
AIM The controversial data related to oxidative stress status in patients with chronic idiopathic urticaria (CIU) have been reported. Therefore, the present study was aimed to contribute to this debate by determining oxidative stress markers along with some trace element levels in patients with CIU. METHODS Twenty-five patients with CIU (10 males, 15 females) and 36 healthy controls were enrolled into the study. Erythrocyte lipid peroxidation status, scavenger enzyme activities and trace element levels were determined. RESULTS While erythrocyte MDA levels, erythrocyte GSH- Px activities and erythrocyte Zn levels showed no differences between the patient and control groups, a statistically significant decrease and increase were observed in erythrocyte CuZn-SOD activities and Cu levels, respectively, in the CIU patients when compared to those of the controls (p < 0.001 for both of them). CONCLUSION In conclusion, an oxidative burden which can be relieved by some preserved antioxidant mechanisms seems to be present in patients with CIU even if they are clinically stable and it may probably have a role in the pathogenesis.

Abstract
CD40 ligand interaction with its receptor (CD40) not only mediates lymphocyte communication, but also associates with chronic inflammation and atherothrombosis. High soluble CD40L (sCD40L) levels were reported in dyslipidemia, diabetes mellitus, and coronary disease. So far, there are no data about sCD40L levels in hypertension. We investigated sCD40L and high sensitive C reactive protein (hsCRP) levels in 30 nonobese young hypertensive men and 30 matched controls. sCD40L and hsCRP levels were not different, and there were no correlations between blood pressure and sCD40L or hsCRP levels. These results might indicate lack of any inflammatory state in new onset hypertension.

Abstract
BACKGROUND Various experimental models related to Adriamycin (ADR)-induced nephropathy have been reported. The purpose of the present study was to evaluate the efficacy of N-acetylcysteine (NAC), deferoxamine (DFO) and selenium in protection against renal injury in ADR nephropathy. METHODS The study included 53 Sprague Dawley male rats. Nephrotic syndrome was induced by injection of ADR 5 mg/kg intravenously (n=46). Control rats (n=7) were injected with an equal volume of isotonic saline. After ADR administration, they were divided into a group given only ADR (n=17) and 3 antioxidant treatment groups: (i) NAC (n=10), (ii) DFO (n=10) and (iii) selenium (n=9). In both renal tissue and erythrocytes, oxidative system parameters and trace elements were determined. RESULTS Nephrotic syndrome was proven in ADR-injected rats 4 weeks after injections, with proteinuria, higher blood lipids and hypoalbuminemia. All of the antioxidant agents used in the present study to prevent the development of nephrotic syndrome provided benefits for the nephrotic state. Of them, selenium seemed to offer relatively lower and statistically insignificant efficacy for preventing proteinuria compared with the others. CONCLUSIONS Our results showed that concomitant administration of some antioxidants with ADR injections seems to have beneficial effects on clinical parameters even if antioxidants were given in a single dose. NAC and DFO are more effective than selenium to prevent renal injury.
