Učestalost epilepsije među studentima Sveučilišta Canakkale Onsekiz Mart, Turska

The aim of this study was to investigate the frequency of epilepsy among students of the Canakkale Onsekiz Mart University. This cross sectional epidemiological study was performed on 4762 of 19,988 Canakkale Onsekiz Mart University students in the academic year 2007-2008. Participants that answered “epilepsy” to the question “Do you have any disease diagnosed by a doctor?” in a questionnaire including 4 subgroups were identified. Data were transferred to the Epi-Info Version 6.0 statistics program and controlled data were analyzed in the SPSS 15.0 statistics program. There were 53.1% of female and 46.9% of male students, mean age 20.4±2.1 (range 17-43) years. Twelve (0.25%) students had epilepsy diagnosis, eight (66.7%) female and four (33.3%) male, mean age 20.8±1.8 years. In our study, epilepsy was detected in 0.25% of students (n=12). Age specific prevalence studies related to epilepsy epidemiology are extremely rare, especially in university students with average intelligence. Thus, we considered that it would be epidemiologically significant to share the results of our cross sectional study with all those involved in epilepsy epidemiology and management.Cilj istraživanja bio je ispitati učestalost epilepsije među studentima Sveučilišta Canakkale Onsekiz Mart, Turska.

Vitamin D receptor gene polymorphisms in multiple sclerosis disease: A case-control study

Multiple sclerosis (MS) is a common neurologic disorder that is a chronic inflammatory, demyelinating, and neurodegenerative disease of the central nervous system (CNS). Its etiology remains unknown. Several recent studies have found that decreased susceptibility to vitamin D deficiency is also associated with a decreased risk of MS. The role of vitamin D receptor (VDR) gene and its polymorphisms are highlighted as susceptible components. In this study, we aimed to identify the relationship between ApaI (rs7975232), BsmI (rs 1544410), and TaqI (rs731236) gene polymorphisms with MS. ApaI, BsmI, and TaqI genotypes were determined in 70 patients with MS and in 70 control subjects. DNA was isolated from blood samples, and then ApaI, BsmI and TaqI gene polymorphisms were identified using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay. The distribution of BsmI and TaqI polymorphisms did not show any significant differences in MS patients and controls; however, increased A allele of ApaI polymorphism was found in MS patients. Our findings suggest that the ApaI gene polymorphism might be associated with MS. Investigation of a larger population and functional work on these gene structures and function in MS patients are recommended

Kurt, Ozlem Kar/0000-0002-4641-2866; Dursun, A. Berna/0000-0002-6337-6326; Karasoy, Duru/0000-0002-2258-4479WOS: 000337624500004PubMed: 24659211Several studies have shown gender differences in prevalence of asthma but there is little information about asthma control. in this study, we aimed to evaluate the effect of gender on asthma control in adult asthmatics. Medical records of 242 patients older than 18 years of age who regularly visited the allergy unit were evaluated. Standardized asthma questionnaires like the asthma control test (ACT) were performed. ACT scores, clinical characteristics, and demographic data such as smoking status, education, duration and severity of asthma, atopic status, family history of asthma, analgesic hypersensitivity, number of emergency visits, and hospitalization in the previous year were compared based on gender. in this study, 77.3% of the patients were female. Mean age, body mass index, and duration of asthma were 39.0 +/- 0.7, 27.3 +/- 0.3, and 6.6 +/- 0.4 years, respectively. of the total, 14.9% of the patients were smokers. Also, 55.8% of them were graduated from middle school, 22.7% from high school, and 14% from university. Atopy rate was 57%. Analgesic hypersensitivity was found in 18.6% of them. There was 30.2% family history of asthma. the asthma severity was mild in 45.5%, moderate in 40.9%, and severe in 13.6% of the patients. One-third of the patients were admitted to emergency room; 1/10th were hospitalized due to asthma in the previous year. ACT scores indicated complete control in 67.8%, partial control in 17.8%, and uncontrolled asthma in 14.5%. Comparing the results of males with females having asthma, there was no statistically significant difference between the two gender according to ACT scores and clinical characteristics. Finally, the results conclude that there was no effect of gender on asthma control assessed with standardized questionnaire in adult asthmatics

Our study aimed to investigate the neuroprotective and anti-oxidant effects of glycyrrhizic acid on focal cerebral ischemia in rats. Twenty-four rats were divided equally into three groups. A middle cerebral artery occlusion model was performed in this study where sham and glycyrrhizic acid were administered intraperitoneally following middle cerebral artery occlusion. Group I was evaluated as control. Malondialdehyde (MDA), superoxide dismutase (SOD), and nuclear respiratory factor-1 (NRF1) levels were analyzed biochemically on the right cerebral hemisphere, while ischemic histopathological studies were completed to investigate the anti-oxidant status. Biochemical results showed that SOD and NRF1 levels were significantly increased in the glycyrrhizic acid group compared with the sham group while MDA levels were significantly decreased. on histopathological examination, cerebral edema, vacuolization, degeneration, and destruction of neurons were decreased in the glycyrrhizic acid group compared with the sham group. Cerebral ischemia was attenuated by glycyrrhizic acid administration. These observations indicate that glycyrrhizic acid may have potential as a therapeutic agent in cerebral ischemia by preventing oxidative stress

Expression of obestatin and ghrelin in papillary thyroid carcinoma

Ghrelin and obestatin are two peptide hormones with opposing roles in the control of appetite: orexigenic and anorexigenic, respectively. Loss of appetite is a common, serious complication of many forms of malignancy. The goals of this study were to investigate: (i) whether there are differences in ghrelin and obestatin peptide expression in thyroid tissues from a series of papillary carcinoma cases and normal controls, and (ii) whether there are correlations between tissue ghrelin and obestatin levels in series of papillary carcinoma cases and normal controls. Immunohistochemical analysis showed that in sections of benign human thyroid tissue, anti-ghrelin antibody reacted with intense staining in colloid-filled follicles. In benign thyroid tissues, colloids displayed plentiful dispersion in comparison with papillary microcarcinomas, whereas colloids in malignant thyroid tissues were uncommon. We found markedly lower tissue ghrelin levels in thyroid tissue of patients with papillary carcinomas, compared with normal thyroid tissues (P = 0.001). Immunohistochemical analysis also showed that obestatin in papillary carcinoma stained positively to various degrees. Obestatin tissue levels in papillary carcinomas tended to be slightly higher than those in normal thyroid tissue, but this was not statistically significant (P = 0.29). We also report that thyroid tissue of patients with Hashimoto's thyroiditis produced ghrelin and obestatin at similar levels as in normal thyroid tissue, even though colloid in Hashimoto's disease is scarce. We conclude that depressed expression of ghrelin, but not obestatin, is specific to papillary carcinoma, and this difference might constitute a diagnostic tool to differentiate papillary carcinoma from normal thyroid tissue. We currently do not know how these peptides are regulated and what factors are involved in papillary carcinoma, which inhibit the expression of ghrelin but not obestatin. This issue warrants further studies.Ghrelin and obestatin are two peptide hormones with opposing roles in the control of appetite: orexigenic and anorexigenic, respectively.

Neuroprotective effects of daidzein on focal cerebral ischemia injury in rats

Daidzein, a plant extract, has antioxidant activity. It is hypothesized, in this study, that daidzein exhibits neuroprotective effects on cerebral ischemia. Rat models of middle cerebral artery occlusion were intraperitoneally administered daidzein. Biochemical and immunohistochemical tests showed that superoxide dismutase and nuclear respiratory factor 1 expression levels in the brain tissue decreased after ischemia and they increased obviously after daidzein administration; malondialdehyde level and apoptosis-related cysteine peptidase caspase-3 and caspase-9 immunoreactivity in the brain tissue increased after ischemia and they decreased obviously after daidzein administration. Hematoxylin-eosin staining and luxol fast blue staining results showed that intraperitoneal administration of daidzein markedly alleviated neuronal damage in the ischemic brain tissue. These findings suggest that daidzein exhibits neuroprotective effects on ischemic brain tissue by decreasing oxygen free radical production, which validates the aforementioned hypothesi

Syringaldehyde exerts neuroprotective effect on cerebral ischemia injury in rats through anti-oxidative and anti-apoptotic properties

There are few studies on the neuroprotective effects of syringaldehyde in a rat model of cerebral ischemia. The study aimed to elucidate the mechanisms underlying the neuroprotective effects of syringaldehyde on ischemic brain cells. Rat models of cerebral ischemia were intraperitoneally administered syringaldehyde. At 6 and 24 hours after syringaldehyde administration, cell damage in the brain of cerebral ischemia rats was obviously reduced, superoxide dismutase activity and nuclear respiratory factor 1 expression in the brain tissue were markedly increased, malondiadehyde level was obviously decreased, apoptosis-related cysteine peptidase caspase-3 and -9 immunoreactivity was obviously decreased, and neurological function was markedly improved. These findings suggest that syringaldehyde exerts neuroprotective effects on cerebral ischemia injury through anti-oxidation and anti-apoptosis

Neuroprotective effect of p-coumaric acid in rat model of embolic cerebral ischemia

Objective(s): Stroke poses a crucial risk for mortality and morbidity. Our study aimed to investigate the effect of p-coumaric acid on focal cerebral ischemia in rats. Material and Methods: Rats were randomly divided into four groups, namely Group I (control rats), Group II (ischemia rats), Group III (6 hr ischemia + p-coumaric acid rats) and Group IV (24 hr ischemia + p-coumaric acid rats). Cerebral ischemia was induced via intraluminal monofilament occlusion model. In all groups, the brain was removed after the procedure and rats were sacrificed. Malondialdehyde, superoxide dismutase and nuclear respiratory factor-1 were measured in the ischemic hemisphere. The histopathological changes were observed in the right hemisphere within the samples. Functional assessment was performed for neurological deficit scores. Results: Following the treatment, biochemical factors changed significantly. Histopathologically, it was shown that p-coumaric acid decreased the oxidative damage. The neurological deficit scores of p-coumaric acid-treated rats were significantly improved after cerebral ischemia. Conclusion:Our results showed that p-coumaric acid is a neuroprotective agent on account of its strong anti-oxidant and anti-apoptotic features. Moreover, p-coumaric acid decreased the focal ischemia. Extra effort should be made to introduce p-coumaric acid as a promising therapeutic agent to be utilized for treatment of human cerebral ischemia in the future

The neuroprotective effect of Sulindac after ischemia-reperfusion injury in rats

PURPOSE: To investigate the neuroprotective effects of Sulindac on the hippocampal complex after global cerebral ischemia/reperfusion (I/R) injury in rats.METHODS: Thirty one Sprague-Dawley rats were used, distributed into group I (sham) n:7 were used as control. For group II (n:8), III (n:8) and IV (n:8) rats, cerebral ischemia was performed via the occlusion of bilateral internal carotid artery for 45 minutes and continued with reperfusion process. 0.3 mL/kg/h 0.9 % sodium chloride was infused intraperitoneally to the Group II rats before ischemia, 5&#956;g/kg/h/0.3 ml sulindac was infused intraperitoneally to the Group III rats before ischemia and 5&#956;g/kg/h/0.3 ml sulindac was infused intraperitoneally to the Group IV rats after ischemia and before reperfusion process. The levels of MDA, GSH and MPO activity were measured in the left hippocampus tissue. The hippocampal tissue of all group members were taken for histopathological study.RESULTS: The MDA and MPO levels increased from group I (control) to group II (I/R) (P<0.05) and decreased from group II (I/R) to group III (presulindac + I/R) and IV (postsulindac + I/R) (P<0.05). Beside these, the GSH levels decreased from group I (control) to group II (I/R) (P<0.05) and increased from group II (I/R) to group III (presulindac + I/R) and IV (postsulindac + I/R) (P<0.05).The number of apoptotic neurons increased from group I (control) to group II (I/R) (P<0.05) and decreased from group II (I/R) to group III (presulindac + I/R) and IV (postsulindac + I/R) (P<0.05).CONCLUSION: The Sulindac may have neuroprotective effects on ischemic neural tissue to prevent the reperfusion injury after ischemia
