Abstract: As studying with population carrying no classical cardiovascular risk factors seems to be an advantage in isolating effects of regular exercise on endothelial functions, inflammatory and thrombotic activity; the present study was designed to evaluate the clear effects of long-term regular exercise in middle-aged, healthy men. A total of 32 regularly exercising (three times per week, 12.8 ± 6.8 years) men (Group I, mean age = 53.2 ± 6. 1 yrs) and 32 sex- and age-matched sedentary subjects (Group II, mean age = 51.0 ± 7.7 yrs) were involved in the study. All participants were non-smokers and with no history of hypertension and diabetes. During one day preceding tests, the subjects refrained from training and maintained their normal diet. In all subjects, body mass index (BMI), percentage of body fat (% BF) and maximal oxygen uptake (VO2max) were calculated. Serum uric acid, glucose, HbA1c, lipids, high-sensitive C-reactive protein (hs-CRP), fibrinogen levels, white blood cell (WBC) and platelet count were measured. Resting heart rates and blood pressures were recorded and standard exercise stress test was applied using the modified Bruce protocol. Flow-mediated and nitrate-induced dilatation (FMD and NID) of the brachial artery and carotid intima-media thickness (cIMT) were evaluated as markers of endothelial functions and early atherosclerosis. Mean BMI, % BF, systolic and diastolic blood pressures, WBC and platelet count, HbA1c, total and LDL cholesterol, hs-CRP and fibrinogen levels were similar between the groups. Group I had significantly lower serum glucose, uric acid and triglyceride (p < 0.05, p < 0.005 and p < 0.05, respectively) and higher HDL cholesterol levels (p < 0.0001) than in Group II. FMD values were significantly higher in Group I than in Group II (p < 0.005) while there were no significant differences in NID and cIMT measures between the groups. VO2max and cIMT showed a negative correlation in Group I (r = -0.463, p < 0.0001). Negative correlations also existed between VO2max and fibrinogen levels in both Group I and II (r = -0.355, p < 0.05 and r = -0.436, p < 0.05, respectively). These results are concordant with the concept of favorable effects of regular physical exercise on cardiovascular health based on enhancement of endothelial functions even in subjects who have low cardiovascular risk profile.

Abstract: Aim: The aim of this study is to evaluate the demographic and other characteristics of the patients hospitalized patients with COPD exacerbations. Material and Methods We evaluated the characteristics of hospitalized patients with COPD retrospectively to determine the causes of hospitalization. Results: Eighty-one patients with COPD were hospitalized 197 times within a year. Hospitalized ones were usually hypercapnic severe COPD patients and patients with a concomitant disease had prolonged hospitalizations. Conclusion: Severe and very severe COPD patients were hospitalized more often. Hospital stay in very severe COPD patients were longer and these patients needed non-invasive and invasive mechanical ventilatory support. Patients with concomitant disease and who were smokers hospitalized more and hospital stay was longer. Mortality was also higher in these patients.

Abstract: The main purpose of the study is to investigate the inversion/eversion muscle strength balance of the ankle in patients with medial tibial stress syndrome (MTSS). A dysbalance of these muscles may play a role in the pathophysiology of MTSS. Another aim is to measure the medial longitudinal arch and navicular drop in patients with MTSS. A total of 11 patients diagnosed with MTSS in the outpatient clinic of Ege University School of Medicine Sports Medicine Department were enrolled in this study. The control group consisted of 11 regularly exercising individuals. The mean age of the patient group and the control group was 21. 0 ± 1.9 years (18-23 years) and 23.2 ± 2.9 years (18-27 years), respectively. A detailed exercise questionnaire was administered to all subjects. Isokinetic muscle strength testing was performed at 30°/sec and 120°/sec to assess invertor and evertor muscle strength of the ankle. Photographs of the weight bearing and non-weight bearing foot were taken to measure the medial longitudinal arch deformation and the navicular drop. At 30°/sec, the average eversion concentric strength was significantly higher in the patient group, and the inversion/eversion strength ratio was significantly higher in the control group (p < 0.05). At 120°/sec velocity, average concentric eversion strength was significantly higher in the patient group (p < 0.05). The measurements of pronation indicators did not reveal any statistically significant differences between the two groups (p > 0.05). MTSS may occur without an increase of pronation indicators like medial longitudinal arch deformation or navicular drop. In such cases, one of the predisposing factors may be the strength dysbalance of the invertor/evertor muscles in favour of the evertor muscles. This observation may be of additional value in the prevention and therapy of MTSS.

Abstract: Medial tibial stress syndrome (MTSS) is a common overuse injury of the lower extremity predominantly observed in weight bearing activities. Knowledge about the pathological lesions and their pathophysiology is still limited. Only a single study was found to have investigated tibial bone density in the pain region, revealing lower density in athletes with long standing (range, 5-120 month) MTSS. In a follow-up study, bone density was determined to return to normal levels after recovery. The purpose of the present study was to investigate tibial bone density in athletes with shorter MTSS history (range, 3-10 weeks). A total of 11 athletes (7 males, 4 females) diagnosed with medial tibial stress syndrome were included in the study. The control group consisted of 11 regularly exercising individuals (7 males, 4 females). Tibial, femoral and vertebral bone densities were measured by dual energy x-ray absorptiometry. Total calcium intake was calculated by evaluating detailed nutrition history. No statistically significant differences were found in the tibial, femoral and vertebral bone densities between the groups. No statistically significant difference was found among groups, considering for calcium intake. Tibial bone densities were not lower in athletes with MTSS of 5.0 weeks mean duration (range, 3-10 weeks) compared to the healthy control group. Longitudinal studies with regular tibial bone density measurements in heavily trained athletes are necessary to investigate tibial density alterations in MTSS developing athletes during the course of the symptoms

Abstract: Anterior cruciate ligament (ACL) is the primary stabilizer of the knee. An impairment of any of the dynamic or static stability providing factors can lead to overload on the other factors and ultimately to deterioration of knee stability. This can result in anterior tibial translation and rupture of the ACL. The purpose of this study was to examine the influence of tibial slope on ACL injury risk on soccer players. A total of 64 elite soccer players and 45 sedentary controls were included in this longitudinal and controlled study. The angle between the tibial mid-diaphysis line and the line between the anterior and posterior edges of the medial tibial plateau was measured as the tibial slope via lateral radiographs. Individual player exposure, and injuries sustained by the participants were prospectively recorded. Eleven ACL injuries were documented during the study period. Tibial slope was not different between soccer players and sedentary controls. Tibial slope in the dominant and non-dominant legs was greater for the injured players compared to the uninjured players. The difference reached a significant level only for the dominant legs (p < 0.001). While the tibial slopes of the dominant and non-dominant legs were not different on uninjured players (p > 0.05), a higher tibial slope was observed in dominant legs of injured players (p < 0.05). Higher tibial slope on injured soccer players compared to the uninjured ones supports the idea that the tibial slope degree might be an important risk factor for ACL injury.

Abstract: The present study investigated the effects of phytoadditive carvacrol on growth performance, feed utilization, hematological, non-specific immune and serum biochemical parameters in rainbow trout (Oncorhynchus mykiss). In trial, 240 rainbow trout which had average weight of 10.79 ± 0.57 was used. Fish were divided into four groups before being fed for 60 days with 0, 1 (C1), 3 (C3) or 5 (C5) g/kg of carvacrol. There were no particular differences in the growth performance, feed utilization, whole body composition, hematological parameters between the experimental group and the control group. However, as compared to control group, a significant increase of serum lysozyme activity was seen in groups receiving feed containing C3 and C5 groups after 30 days. The myeloperoxidase activity in groups (C1 and C3) was significantly higher on the 30th day of sampling. Myeloperoxidase activity of C5 treated group was significantly higher on the 60th day in comparison with the control group. Serum glucose levels significantly decreased on 60th day for C1, C3 and C5 treated groups. The serum total protein, globulin and triglyceride levels of C3 treated groups was significantly higher on the 60th day in comparison with the control and other carvacrol treated groups. The level of serum cholesterol in C5 treated groups was significantly lower on the 30th day in comparison with the control and other carvacrol treated groups. The results of the present study indicated that dietary supplementation of 3 g/kg of carvacrol in commercial diets could improve some non-specific and biochemical status in rainbow trout.

Mathematical Problems in Engineering , 2009, DOI: 10.1155/2009/527452
Abstract: Determination of exact standard time with direct measurement procedures is particularly difficult in companies which do not have an adequate environment suitable for time measurement studies or which produce goods requiring complex production schedules. For these companies new and special measurement procedures need to be developed. In this study, a new time estimation method based on different robust algorithms of artificial neural networks (ANNs) is developed. For the proposed method, the products that have similar production processes were chosen from among the whole product range within the cleansing department of a molding company. While using ANNs, to train the network, some of the chosen products' standard time that had been previously measured is used to estimate the standard time of the remaining products. The different ANN algorithms are trained and four of them, which are converged the data, are stated and compared in different architectures. In this way, it is concluded that this estimation method could be applied accurately in many similar processes using the relevant algorithms.
