Abstract: objective: this retrospective study aimed to investigate the relationship between admission levels of serum y-glutamyltransferase and poor myocardial perfusion after primary percutaneous coronary intervention in patients with acute myocardial infarction. introduction: reperfusion injury caused by free radical release and increased oxidative stress is responsible for the pathophysiology of the no-reflow phenomenon in patients with acute myocardial infarction undergoing primary percutaneous coronary intervention. serum ?-glutamyltransferase is an established marker of increased oxidative stress. methods: the study population consisted of 80 patients (64 men and 16 women, mean age = 67.5 + 6.6 years) with thrombolysis in myocardial infarction 0/1 flow pre-procedurally. the patients were divided into two groups according to thrombolysis in myocardial perfusion grades that were assessed immediately following primary percutaneous coronary intervention. the two groups (group 1 and group 2) each consisted of 40 patients with thrombolysis in myocardial perfusion grades 0-1 and thrombolysis in myocardial perfusion grades 2-3, respectively. results: admission pain to balloon time, ?-glutamyltransferase and creatine kinase-mb isoenzyme levels of group 1 patients were significantly higher than those of group 2 patients. pain to balloon time, ?-glutamyltransferase, peak creatine kinase-mb isoenzyme, low left ventricular ejection fraction and poor pre-procedural thrombolysis in myocardial infarction grade were significantly associated with poor myocardial perfusion by univariate analysis. however, only pain to balloon time and ?-glutamyltransferase levels showed a significant independent association with poor myocardial perfusion by backward logistic regression analysis. adjusted odds ratios were calculated as 4.92 for pain to balloon time and 1.13 for ?-glutamyltransferase. conclusion: high admission ?-glutamyltransferase levels are associated with poor myocardial perfusion in pa

Abstract: The article investigates the similarities and differences between all versions of Grand Theft Auto as an adventure game with the widest popularity in the last decade. The game is a story collection, a frame for performance, a virtual museum of vernacular culture and a widely circulated pop culture artifact whose double-voiced aesthetic has given rise to diverse interpretive communities. The aim of comparing the differences and similarities between different versions of the game is to be able to evaluate the game from the user’s point of view. With this aim, whether with the verisimilitude that the different versions offer makes GTA a product of an iterative design process or not will be displayed.

Abstract: Efforts to find an ideal model for pancreatitis date back to 1960’s. Many models are suggested since then. Every model has its own advantages and disadvantages. Some of these models test etiology while others simulate the complications of pancreatitis. An ideal model which by itself demonstrates all aspects of pancreatitis including systemic changes is yet to be described. In this review we tried to gather the basic, easy to construct models.
Towards Earthquake Shields: A Numerical Investigation of Earthquake Shielding with Seismic Crystals  [PDF]
Baris Baykant Alagoz, Serkan Alagoz
Open Journal of Acoustics (OJA) , 2011, DOI: 10.4236/oja.2011.13008
Abstract: Authors numerically demonstrate that the seismic surface waves from an earthquake can be attenuated by a seismic crystal structure constructed on the ground. In the study, seismic crystals with a lattice constant of kilometer are investigated in the aspect of band gaps (Stop band), and some design considerations for earthquake shielding are discussed for various crystal configurations in a theoretical manner. Authors observed in their FDTD based 2D wave simulation results that the proposed earthquake shield can provide a decreasing in magnitude of surface seismic waves. Such attenuation of seismic waves might reduce the damage in an earthquake.
Optic Nerve Head Drusen, Myopia and Ocular Hypertension: A Case Report  [PDF]

Open Journal of Ophthalmology (OJOph) , 2014, DOI: 10.4236/ojoph.2014.41001
Abstract:

A 20-year-old male patient presented at our clinic complaining of strange visual experiences (neither decreased nor blurred) and a mild headache while reading. His best corrected visual acuity revealed 20/20 with a fort myopic correction. Intraocular pressures measured with Dynamic Contour Tonometer (DCT) (Swiss Microtechnology AG, Port, Switzerland) were 23.3 mmHg in the right eye (OD) and 27.4 mmHg in the left eye (OS) with cenral corneal thicknesses (CCTs) of 588 (OD) and 591 (OS) microns, respectively. Optic discs were bilateral pale with indistinct and scalloped margins without cupping. Red free photos showed autofluorescence of both optic discs, representative of optic disc drusen. Visual field analysis (VFA) of both eyes revealed sensitivity depression with localized defects consistent with the Optical Coherence Tomography (OCT) findings. Optic nerve head drusen (ONHD), myopia and high intraocular pressures (IOPs), may cause ganglion cell damage resulting in RNFL thinning and visual field loss. Because of the difficulty in detecting the exact cause and the extent of the damage, patients with ONHD associated with high IOPs and myopia should be examined closely with serial monitoring using OCT and VFA. In case of RNFL thinning and visual field

Salud Pública de México , 1998, DOI: 10.1590/S0036-36341998000300009
Abstract: this paper examines the current health care reform issues in canada. the provincial health insurance plans of the 1960s and 1970s had the untoward effects of limiting the federal government?s clout for cost control and of promoting a system centered on inpatient and medical care. recently, several provincial commissions reported that the current governance structures and management processes are outmoded in light of new knowledge, new fiscal realities and the evolution of power among stake-holders. they recommend decentralized governance and restructuring for better management and more citizen participation. although canada?s health care system remains committed to safeguarding its guiding principles, the balance of power may be shifting from providers to citizens and "technocrats". also, all provinces are likely to increase their pressure on physicians by means of salary caps, by exploring payment methods such as capitation, limiting access to costly technology, and by demanding practice changes based on evidence of cost-effectiveness.

International Journal of Nephrology , 2013, DOI: 10.1155/2013/248416
Abstract: The present study was carried out to investigate independent relationship between daily physical activity, microalbuminuria, and kidney function. The demographic characteristics and laboratory parameters were recorded for all patients. The determination of daily activities was carried out by Nottingham Extended Activities of Daily Living Scale (NEADLS) which was performed for each patient in an interview. Totally 139 patients were enrolled. In the whole group NEADLS score was correlated with age (rho: ?0.759, ), clinical systolic blood pressure (rho: ?0.212, : 0.018), blood urea nitrogen (rho: ?0.516, ), creatinine (rho: ?0.501, ), uric acid (rho: ?0.308, ), albumin (rho: 0.382, ), total cholesterol (rho: ?0.194, : 0.022), LDL-cholesterol (rho: ?0.230, : 0.008), hemoglobin (rho: 0.256, : 0.002), creatinine clearance (rho: 0.565, ), 24-hour urinary protein excretion (rho: ?0.324, ), and 24-hour urinary albumin excretion (UAE) (rho: ?0.483, ). The multivariate linear regression of independent factors corelated with logarithmically converted NEADLS score (as a dependent variable) has shown that age ( ), presence of coronary artery disease ( : 0.011), hemoglobin ( : 0.020), 24-hour creatinine clearance ( : 0.004), and 24-hour urinary albumin excretion ( ) were independently corelated with NEADLS score. In conclusion, both UAE and kidney function were independently associated with daily physical activity. 1. Introduction Patients with chronic kidney disease (CKD) often have decreased physical fitness and activity [1]. The main causes are muscle atrophy [2], myopathy [3], inactivity [4], malnutrition [5], and lower albumin levels [6]. Besides, anemia, inflammation, and uremic acidosis also play a role [7]. It was well demonstrated that increased urinary protein and albumin excretion are well-known risk factors for cardiovascular end-organ damage [8, 9]. Emerging data suggest that greater physical activity may be associated with less albuminuria and physical activity could protect against albuminuria [10, 11]. However, the relationship between physical activity and albuminuria is not uniform. For example, in diabetic patients, physical activity is associated with lower albumin excretion, and physical activity has led to regression of albuminuria in interventional studies [12, 13]. However, in nondiabetics these associations were not observed [14, 15]. The relationship between physical activity and albumin/protein excretion become more complex by the phenomenon of postexercise proteinuria. Transient proteinuria, including albuminuria, is common after intense
Uniform 1-Cochains and Genuine Laminations

Abstract: We construct a pair of transverse genuine laminations on an atoroidal 3-manifold admitting transversely orientable uniform 1-cochain. The laminations are induced by the uniform 1-cochain and they are indeed the "straightening" of the coarse laminations defined in [Ca], by using minimal surface techniques. Moreover, when you collapse these laminations, you can get a topological pseudo-Anosov flow, as defined by Mosher, [Mo].
