Abstract: OBJECTIVE: Vascular calcifications and chronic inflammation are the main reasons of the decreased life span and prevalent morbidity for patients on renal replacement therapy due to chronic renal failure. Scoring systems used to determine the chance of cardiovascular (CV) risk and traditional CV risk factors frequently fail to identify the risk in these patients. New markers to predict the risk of CV disease continues to be investigated. One of the most studied marker in recent years is a serum glycoprotein fetuin-A, which is major calcification inhibitor. We aimed to study the relation between fetuin-A subclinical inflammation and cardiovascular risk factors in Peritoneal Dialysis (PD) patients and healthy volunteers.MATERIAL and METHODS: Forty-eight PD patients and 27 healthy volunteers were included in the study. Fetuin-A levels, body weight, body mass index, blood pressure, markers of inflammation (sedimentation, C-reactive protein, ferritin) and lipid profile tests were performed. The relationship between these parameters was compared with fetuin-A.RESULTS: CRP and sedimentation levels were significantly higher in the group of PD patients. Fetuin-A levels were significantly lower in PD patients than the control group. There was a negative correlation between serum fetuin-A levels, average arterial blood pressure and CRP.CONCLUSION: Fetuin-A can be used to predict subclinic inflammation, and cardiovascular mortality risk in PD patients.

Abstract: Objective: Methylphenidate is the most commonly prescribed psychostimulant and is indicated in the treatment of attention-deficit hyperactivity disorder. There have been concerns about potential adverse effects of long-term methylphenidate administration on the brain. The purpose of this study is to investigate antioxidant system and lipid peroxidation in order to evaluate the potential adverse effects of methylphenidate on the brain. Methods: Methylphenidate at doses of 2 mg/kg (n=10) and 10 mg/kg (n=10) via gavage was administered to young Wistar rats (n=10) for 5 weeks, whereas the controls (n=10) were given saline solution. Methylphenidate and saline solution were given orally and twice daily to match human medication. Superoxide dismutase, glutathione peroxidase, and malondialdehyde were measured in hippocampus, cerebellum, striatum, and frontal cortex of rat brains. Results: Methylphenidate at doses of 2 mg/kg and 10 mg/kg increased the levels of malondialdehyde in the striatum compared to the control group (p<0.01). At a dose of 10 mg/kg, methylphenidate decreased the superoxide dismutase activity in the frontal cortex compared to 2 mg/kg methylphenidate (p<0.05). However, there was no effect on glutathione peroxidase activity. Discussion: The present study suggests that at doses of both 2 mg/kg and 10 mg/kg, the long-term methylphenidate treatment causes lipid peroxidation in the striatum of rat brain. Future studies should be conducted to examine whether antioxidant supplementation can prevent the brain tissue from methylphenidate induced oxidative stress.

Abstract: Serious land degradation have been occurring during the building of new roads associated with the construction of Deriner Dam, one of 15 large dams planned by the General Directorate of State Hydraulic Affairs and implemented within the Coruh Dam Projects. In this study, whether terracing and planting of seedling efforts in degraded areas as a result of building new roads within erosion control and reforestation efforts have any effect on improving soil characteristics were investigated. In accordance with this purpose, parameters including soil texture, pH, organic matter, total nitrogen, total lime, and electrical conductivity were determined for 45 soil samples taken from three different areas; two of which were erosion control areas where terraces built and planted with acacia and yellow pine seedlings, along an undisturbed (control) area with natural forests. After evaluating statistical analyses run on the soils data, it was determined that the reforestation efforts have resulted in improvements of soil properties at some degree but when they are compared to the soils of the undisturbed natural forest, it is clear that the degree of improvement is not sufficient yet. For example, while the organic matter of 3.71% and pH of 7.69 were determined for the forest area, same parameters were found as 1.13% and 7.99 for the acacia and 0.86% and 7.93 for the yellow pine areas, respectively.
Frequent injuries in adolescent athletes

Abstract: As a result of the decrease in the age of starting doing sports and competition, the frequency and the variety of the athletic injuries in the childhood and adolescence have increased. The results of the similar traumas in the adulthood and adolescence are different from each other. While the rapid anatomic development and growing-up in adolescence affects the performance in a negative manner, it also increases the risks of the athletic injuries. In adolescence the frequency of both, microtraumatic overuse and uni-traumatic (in-or extrinsic) injuries are similar. The athletic injuries are closely related to the executed discipline. The apophysitis’, ligament injuries, stress fractures, tendonitis, ostheochondral injuries, syndesmosis injuries, avulsion fractures, impingement syndromes and spondylolyses are the mostly experienced ones.

Abstract: Using the basic ingredient of two-body problem, we propose accurate algebraic solutions in a closed form for the ground state of helium and helium-like atoms. These simple but explicit expressions involve exact screening parameters for each system considered and provide an insight into their physical structure. The energy eigenvalues have been exactly calculated for atoms with nuclear charge Z in the range 1 ≤ Z ≤ 12, clarifying the relation between the screening parameteter and Z.
The Performance of the Higher-Order Radiation Condition Method for the Penetrable Cylinder

Abstract: We have considered the scattering of a plane wave by a penetrable acoustic circular cylinder. The boundary conditions are continuity of the total pressure and the total velocity. The wave speed and density of the target are different from that of the surrounding medium. We investigated the performance of higher-order SRCs up to L4 operator in two dimensions. We assume that in the rectangular Cartesian system of axes, (x,y,z), the z axis coincides with the axis of the cylinder and an incident wave propagates in a direction perpendicular to the z axis. All the field quantities are then independent of z. Numerical results are added to present the change of the module of the total field and the magnitude of the far field with respect to θ.

Abstract: The research carried out with the permission of General Directorate of Monuments and Museums, Culture and Tourism Ministry of Turkish Republic, between 9 to 26 July 2010 in the center of Mu , Varto, Korkut and Hask y towns.In the research, cultural assets which were three churches, a store, a fountain, monument consisting of six houses and thirteen cemeteries were identified and examined.The houses in the center of Mu are generally made of mud brick with two-storey. The houses at Minaret, the castle and the River districts are disappearing rapidly, because they remain in the center of the city. They indicate the characteristic feature of Mu especially with front-side arrangements.The tombstones found in Varto district are noteworthy with human and animal figure forms. The tombstones identified in villages of Hask y and Korkut towns stand with the sword and shield motifs.Memorial monuments and tombstones vary in terms of materials, forms and style according to region and periods. The works identified usually belong to the Ottoman (XVI-XIX centuries) period.The searched cemeteries were found to be different from each other. It is important to demonstrate the richness of the geography of Mu . Some of the motifs over the Headstones indicate differences, especially compared to other provinces in the region.Historical graves in the cemetery are rapidly destroyed by natural and human factors gradually. In addition, all new burials in cemeteries today increase the destruction. zetT.C.
