To investigate whether nitrite levels were abnormally high in expired breath condensate (EBC) from workers with asthma-like syndrome. Materials and methods: We measured the nitrite levels in EBC from 48 volunteer workers, including 25 smokers, with asthma-like syndrome before and after SO2 exposure and compared these levels with those from 44 nonexposed control subjects, including 23 smokers. Results: Baseline concentrations of nitrite in the workers before SO2 exposure were higher (19.31 ± 1.06 nmol/mL) than in the controls (13.08 ± 1.36 nmol/mL; P < 0.001). Acute SO2 exposure produced a significant increase in concentrations of nitrite (23.62 ± 1.36) compared to the baseline value (P < 0.05). Preexposure nitrite concentrations were similar in smoking and nonsmoking workers (17.85 ± 1.72 and 20.20 ± 1.59; P > 0.05). Conclusion: We concluded that nitrite levels in EBC are increased in the asthma-like syndrome induced by …

To investigate the role of the oxidative stress status of drivers involved in traffic accidents as a risk factor. Materials and methods: Twenty-six drivers and 28 passengers involved in traffic accidents and 31 healthy control drivers and 30 healthy control pedestrians were enrolled in the present study. The total antioxidant status (TAS) and total oxidant status (TOS) were measured in blood samples. Results: The mean value of the TOS level in drivers involved in traffic accidents was significantly higher than that of the control pedestrians (P =< 0.05). The mean value of the TAS level in passengers involved in traffic accidents was significantly lower than that of the control drivers and pedestrians (P =< 0.001 and P =< 0.01, respectively). Conclusion: This is the first study assessing the oxidative markers of individuals involved in a traffic accident compared with a control group. The results reveal that involvement in a traffic accident has an effect on oxidative markers. However, further studies are required in order to use the oxidative stress status of drivers involved in traffic accidents as a marker for estimating the accident risk.

Turkish Journal of Medical Sciences
Aim: To examine the possible preventive effect of N-acetylcysteine (NAC) on biofilm formation in Staphylococcus epidermidis strains, which cause very important problems such as implant-associated infections in hospitalized and immunocompromised patients worldwide. Materials and methods: The effects of varying concentrations of NAC on the formation of biofilm by 28 strains of Staphylococcus epidermidis was investigated spectrophotometrically by micro-ELISA assay. Results: Significant differences in biofilm formation in the presence of various NAC concentrations were found in 15 methicillin-resistant Staphylococcus epidermidis and 13 methicillin-sensitive Staphylococcus epidermidis strains (P < 0.05). Conclusion: It was found that slime formation was decreased due to the increased concentrations of the NAC treatments. Based on these findings, it is possible to use NAC as an antibiofilm agent on medical devices or in catheter lock solutions to prevent colonization and implant-associated infections.

Btla (C272) Expression On Cd4+ T Cells In Behçet Patients, Nafi̇ye Fulya İlhan, Nesri̇n Demi̇r, Tamer Demi̇r, Ahmet Gödekmerdan
Turkish Journal of Medical Sciences
To investigate the peripheral blood levels of B and T lymphocyte attenuator (BTLA/CD272) on T cells and its role in Behçet disease (BD), and to define the role of inhibitory receptors on BD. Materials and methods: Included in this study were 25 patients with BD and 20 healthy control subjects, matched for age and sex. Results: CD4+CD272+ (P < 0.001) and CD3+CD272+ (P < 0.001) T cell levels were significantly higher in BD patients (active and remission) compared to the healthy controls. However, there was no difference between the active patients and those in remission in terms of CD4+CD272+ T cells, while CD3+CD272+ T cell levels were significantly higher in active-phase BD patients compared to patients in the remission phase (P < 0.05). Conclusion: Further functional studies could be implemented to investigate the effectiveness of the present research parameter in the diagnosis or follow-up of certain diseases similar to BD and with obscure etiology, as well as its contribution to immune dysregulation of BD. BTLA can additionally modulate T cell response in BD on different inflammatory areas and it can be upregulated in BD because of T cell activation. The results of the present study indicate that BTLA expression on CD4+ Th (T helper) cells might play a limiting role on the inflammation at peripheral sites or organs in BD.

The aim of this study was to evaluate shoulder functions after neck dissection with preservation of the spinal accessory nerve by objective physical examination, electromyographic findings, and subjective patient complaints, and also to investigate the effect of the type of neck dissection. Materials and methods: The present study included 29 patients on whom unilateral selective or modified radical neck dissection was performed for head and neck cancer and/or metastasis to the neck. Electromyographical findings, range of motion, and pain scores of the shoulder joint were determined for the operated and nonoperated (control) sides. Results: An electromyographic examination of the trapezius …

To analyze the characteristics of patients transferred by air ambulance in the eastern Anatolia region of Turkey. Materials and methods: We retrospectively evaluated the records of patients transferred by air ambulance between January 2010 and December 2010. Demographics and medical data of the patients, geographic conditions, and flight duration data were all analyzed. Results: A total of 241 patients were included in the study, of whom 51% were men and 49% were women. The majority of the patients were between 0 and 1 year old (40.2%). In the adult patients, the most commonly seen diagnoses were trauma (31.6%), obstetric problems …

We aim ed to predict mortality in stroke patients by using multilayer perceptron (MLP) neural networks. Materials and methods: A data set consisting of 584 stroke patients was analyzed using MLP neural networks. The effect of prognostic factors (age, hospitalization time, sex, hypertension, atrial fibrillation, embolism, stroke type, infection, diabetes mellitus, and ischemic heart disease) on mortality in stroke were trained with 6 different MLP algorithms [quick propagation (QP), Levenberg-Marquardt (LM), backpropagation (BP), quasi-Newton (QN), delta bar delta (DBD), and conjugate gradient descent (CGD)]. The performances of the MLP neural network algorithms were compared using the receiver operating characteristic (ROC) …

The aim of the present study was to investigate the relationship between liver damage induced by carbon tetrachloride (CCl_4) and adenosine deaminase (ADA), 5'-nucleotidase (5'NT), xanthine oxidase (XO) enzyme activities, and malondialdehyde (MDA) levels. The effect of stobadine on purine metabolism was also evaluated. Materials and methods: This study measured the effect of CCl_4 on ADA, 5'NT, XO enzyme activities, and MDA levels, and measured the histopathologic changes in liver cells. Results: Our research found that ADA, XO activities, and MDA levels increased in the CCl_4 group when compared with the control group. This was also supported by the histopathological …
