- MakaleAçık Erişim2012Is Increased Mean Platelet Volume a Risk Factor in Patients with Acute Deep Vein Thrombosis?
Kalkan, Asim; Memetoglu, Mehmet Erdem; Bilir, Ozlem; Ersunan, Gokhan; Kutlu, Rasim; Tutar, Nuri
Objectives The purpose of this retrospective study was to compare the mean platelet volume between the patients with acute deep vein thrombosis (DVT) and control subjects. Methods Data were collected retrospectively from the patients' medical records. The study group consisted of 110 patients with newly diagnosed acute DVT in the lower extremities. An age, gender, and body mass index-matched control group consisted of 98 patients with normal duplex ultrasound findings. We compared the mean platelet volume in patients with acute DVT and control participants. Results There was no significant difference between the study and control groups in mean platelet volume (8.8 +/- 1.6 vs 8.7 +/- 1.3 fl, respectively; p>0.05). Age (p=0.899), body mass index (p=0.43), gender (p=0.466), and platelet count (p=0.886) were statistically similar in both groups. Conclusions There was no significant difference in mean platelet volume between patients with acute DVT and the control group. According to our result, we propose that mean platelet volume should not be considered as an index of acute DVT.

Ertas, Gokhan; Kozdag, Guliz; Emre, Ender; Akay, Yasar; Ural, Dilek; Hebert, Kathy
Mean platelet volume (MPV) is increased in chronic heart failure (CHF) and is an independent predictor of mortality in CHF patients. It is not known whether enhanced external counterpulsation (EECP) therapy leads to decreased MPV values or not. The purpose of this study was to examine the effects of EECP on platelet count and MPV values and to assess the influence of MPV on the risk of death and recurrent ischemic events in ischemic CHF patients. A total of 68 ischemic heart failure patients with CHF symptoms and refractory angina pectoris were included in the study, 47 consecutive patients (39 males and eight females) aged 44-82 years. Although follow-up period started after completion of EECP in treated patients, control group follow-up started at the end of 7-week treatment without EECP. All patients were monitored for a mean duration of 13 +/- 8 months (range, 1-36 months). The primary endpoints of the study were effects of EECP treatment on platelets after treatment period (7 weeks) and the recurrence of ischemic events. Secondary endpoint was cardiovascular death during the follow-up period. We observed a significant increase in platelet count and decrease in MPV levels (P=0.044 and P=0.004, respectively) in the control group. There were no significant differences in platelet count and MPV levels in the EECP group (P>0.05). After the treatment period, New York Heart Association functional classification (2.60 +/- 0.75 vs. 1.72 +/- 0.68, P<0.001) and Canadian Cardiovascular Society functional classification of angina (2.50 +/- 0.90 vs. 1.60 +/- 0.74, P<0.001) improved in patients with EECP treatment. In our study, we found that EECP therapy had a neutral effect on MPV values and platelet count Blood Coagul Fibrinolysis 23:127-131 (C) 2012 Wolters Kluwer Health vertical bar Lippincott Williams & Wilkins.

Akpinar, Salih; Temiz, Semsettin; Aydin, Murat Demir; Özel, Adnan
In this work, elasto-plastic stress analysis of single lap joints with and without protrusion in adhesive bondline subjected to tension and bending was carried out using 2D non-linear finite element analysis and confirmed experimentally. AA 2024-T3 aluminum adherends were bonded with SBT 9244 film adhesive. The protrusion was obtained by extending the adhesive film by 2 mm from the overlap length at both overlap ends. Three different adherend thicknesses and overlap lengths for each loading and bondline type were used. The joints with and without protrusion, for comparison, were loaded with the same load for each adherend thickness and overlap length. Finally, it was observed that the protrusion reduces the strength in the joint under tension, while the protrusion increases the strength in the joint under bending.

Sevim, Baris; Altunisik, Ahmet Can; Bayraktar, Alemdar; Akköse, Mehmet; Adanur, Suleyman
Using experimental methods, this study presents the estimation of the dynamic and static ( secant) elasticity modules of a prototype arch dam. These experimental methods are ambient vibration tests, uniaxial compression tests, and ultrasonic velocity tests. Implementation of the methods on a prototypical arch dam-reservoir-foundation model of the dam, constructed under laboratory conditions, allows estimation of the elasticity modules. Random impact loads excite the arch dam during ambient vibration testing, which creates response signals for measurement. Commercially available software transfers the signals, and processing those signals allows estimation of the experimental natural frequencies of the arch dam. Analysis of a three-dimensional (3D) finite element model (FEM) of the arch dam determines natural frequencies. The estimation of the elasticity modules of the arch dam arises from a comparison of the experimental and analytical frequencies. The uniaxial compression tests use several specimens of the fresh and hardened concrete of the prototype model, and those tests provide the compressive strengths and stress-strain relationships. The ultrasonic velocity tests apply several velocity measurements to the arch dam and foundation, resulting in estimation of the elasticity modulus from empirical equations related to concrete mix design, compressive strength, and velocity values. This study discusses the difficulties of the determination of the elasticity modulus and suggests that ambient vibration testing and the finite element method are useful for overcoming these difficulties.

Atamturktur, S.; Sevim, B.
This article discusses a combined analytical and experimental study on the nonlinear seismic performance of two Guastavino-style masonry domes located in the United States. The seismic performance of these masonry domes is simulated with nonlinear finite-element (FE) models. To support the assumptions and decisions established during the development of the FE models, the vibration response of the domes is measured on-site and systematically compared against the numerical model predictions. Linear FE models are developed that are in close agreement with the measured natural frequencies and in visual agreement with the measured mode shapes. Next, these linear models are extended into the nonlinear range by incorporating the Drucker-Prager damage criterion. Finally, nonlinear FE models are used to assess the performance of these two domes under seismic loadings obtained from the 1940 El Centro earthquake acceleration records. The predicted displacements and internal tensile stress levels are used to make inferences about the potential behavior of these two buildings under the selected earthquake load.

Çobanoglu, Ufuk; Melek, Mehmet; Kara, Volkan; Mergan, Duygu
Aim: The aim of this study was to review cases with isolated hemothorax after thoracic trauma, to assess the diagnostic and treatment methods, and to discuss the determining factors of morbidity and mortality. Material and Method: A total of 57 patients were examined retrospectively. All patients underwent tube thoracostomy and underwater seal as the initial treatment approach. Emergency thoracotomy was performed on cases with continuing drainage from the chest tube, expanding hemothorax on the posteroanterior (PA) chest x-ray, and with hemodynamic instability. Result: Hemothorax occurred as a result of penetrating trauma in 31 (54.38%) and due to blunt trauma in 26 (45.61%) cases. Of the cases, 49 (85.96%) underwent tube thoracostomy drainage. All the 8 cases (14.03%) that underwent emergency thoracotomy had penetrating trauma. Mortality occurred in one patient (1.75%) who had penetrating trauma and who underwent emergency thoracotomy. The morbidity rate in patients with blunt trauma was significantly higher than those with penetrating trauma (p<0.0001). Discussion: Accurate diagnosis and appropriate surgical intervention in cases with traumatic hemothorax is essential for reducing the morbidity and mortality. Chest tube insertion and underwater seal application should be the initial treatment modality and successful in most cases. Emergency thoracotomy is life-saving in indicated patients. The need for thoracotomy is higher in isolated hemothorax due to penetrating chest trauma.

PURPOSE We aimed to present the short- to mid-term results of endovenous laser ablation (EVLA) procedures that were used to treat great saphenous vein (GSV) insufficiency. MATERIALS AND METHODS This prospective study was conducted between December 2009 and January 2011. A total of 112 incompetent GSVs were treated using EVLA with a 940 nm wavelength laser. Ninety patients were treated for varicose veins with saphenous reflux, including 36 females (40%) and 54 males (60%). These patients' ages ranged from 17 to 79 years (median, 48 years). After the EVLA, the patients were monitored using duplex ultrasonography and were assessed clinically at 1 week and 1, 3, 6, and 12 months after the surgery. The patients were scheduled for a three-day examination after the EVLA to assess the level of pain that each patient was experiencing in each limb. RESULTS At the end of a one-year follow-up period, the postprocedural duplex scans revealed a total occlusion of the treated GSVs in 88 (97%) patients and a sub-total occlusion in two (2%) patients. The average modified clinical, etiological, anatomical, and pathological score was significantly decreased at 12 months. The following complications were observed in the present study: hypoesthesia (11%), swelling and induration (5%), skin pigmentation (5%), deep vein thrombosis (1%), erythema (1%), and bleeding (1%). The mean visual analog pain score for the entire procedure was 3.14 +/- 1.06. CONCLUSION Our short- and mid-term results of the EVLA procedure were satisfactory, and the results of this study reaffirmed the safety and effectiveness of an EVLA using a 940 nm wavelength for the treatment of GSV insufficiency.

Southeastern Anatolia Project (GAP) region in Turkey is rich in water for irrigation and hydroelectric power. The Euphrates and Tigris Rivers represent over 28% of the nation's water supply by rivers, and the economically irrigable areas in the region make up 20% of those for the entry country. Turkey has a total gross hydropower potential of 433 GWh/yr, but only 125 GWh/yr of the total hydroelectric potential of Turkey can be economically used. By the construction of new hydropower plants, 36% of the economically usable potential of the country would be tapped. The GAP region has a 22% share of the country's total hydroelectric potential, with plans for 22 dams and 19 hydroelectric power plants. Once completed, 27 billion kWh of electricity will be generated annually. (C) 2011 Elsevier Ltd. All rights reserved.

Background: LigaSure™ (Covidien, Mansfield, MA) has been used in cases undergoing laparoscopic colon and rectal resections. This study aims to analyze the efficacy and safety of the 5-mm and 10-mm devices. Subjects and Methods: Patients who received a laparoscopic or hand-assisted laparoscopic operation for a tumor located in the sigmoid colon or rectum since 2006 were abstracted from a prospectively designed database, and findings were analyzed in two groups based on size of the device used during the procedure. The videotapes of the procedures were watched, and operation reports were read to obtain further information on specific intra- and postoperative complications. Demographics, tumor and operation-related information, and postoperative data were compared. Results: Among 215 (128 [59.5%] males; median age, 59.5±13.8 years) patients, data obtained from the 5-mm (n=32) and 10-mm (n=183) groups were identical regarding demographics and data related to tumor (localization and stage) and operation (number of harvested lymph nodes, conversion rates, operation time, intraoperative bleeding, transfusion requirement, reoperation rates, complications, 30-day mortality, and length of hospital stay). However, more patients underwent an anterior resection in the 10-mm group than in the 5-mm group (31.7% versus 15.6%, P<.05). Further analyses found device-related bleeding in 8 (3.7%) cases (2 [6.3%] versus 6 [3.3%] in the 5-mm versus 10-mm group, respectively, P>.05), requiring further attempts for hemorrhage control (n=6), conversion to open surgery (n=1), or relaparotomy (n=1). Conclusions: The 5-mm and 10-mm LigaSure devices are similarly effective and safe during laparoscopic sigmoid colon and rectal resections. Severe bleeding from larger vessels may be observed, requiring conversion to open surgery or relaparotomy.

Cakir, Tufan; Livaoglu, Ramazan
The paper describes a simple, efficient and reasonably accurate analytical model for analysis of backfill-rectangular tank-fluid interaction systems. The presented model uses Housner's two-mass approximation for fluid interaction and mass-spring-dashpot system for backfill interaction and accommodates a variety of features that may affect the behavior of rectangular tanks including fluid volume, backfill geometry, soil properties and flexible/rigid wall types. Unlike the conventional finite element and the finite difference models that require considerable effort and knowledge to prepare the input data, the proposed model requires only a few pieces of data to define the problem and control the analysis. A series of finite element simulations were also fulfilled on two real rectangular tanks subjected to backfill and fluid effects. A reasonably good accord was obtained comparing the analytical predictions to results from numerical simulations. Thus, it can be stated that the model may be used effectively to perform a broad suite of parametric studies at the design stage and also as a reliable tool for estimating the system behavior. The results obtained from parametric seismic analyses indicated that backfill interaction, wall flexibility and fluid interaction considerably affect the lateral displacements. The sloshing response, however, was not practically affected by the backfill interaction and the wall flexibility.

Öztürk, Serkan; Bayrak, Yusuf
A statistical analysis is made for the eastern part of Turkey in the beginning of 2009 by studying the phenomenon of seismic quiescence as a potential precursor of the main shocks. The results produced four areas having seismic quiescence in the beginning of 2009. These areas are observed to be centered at 39.96°N-40.69°E (around Aşkale, Erzurum), 39.36°N-39.74°E (around Ovaci{dotless}k, Tunceli), 39.02°N-40.52°E (including Elazi{dotless}ǧ and Bingöl), and 38.45°N-42.94°E (Van Lake). Based on the recent results showing 5 ± 1.5 years quiescence before the occurrence of an earthquake in this region, the future earthquake would be expected between 2009. 5 and 2010. 5. The future earthquake occurrence may reach 2012 if we consider the standard deviation of average seismic quiescence as ±1.5 years. We have found that the MW = 6.0 Elazi{dotless}ǧ earthquake on 8 March 2010, followed a seismic quiescence starting about 5 years before the main shock. Thus, special interest should be given to the other regions where the seismic quiescence is observed.

This study aims to forecast the world's, European Union's (EU), and Turkey's electricity energy generation until 2030. For this purpose, the electricity energy sector of the world, EU, and Turkey was overviewed from past to present. The total electricity energy generation for the world, EU, and Turkey were then modelled by using historical energy generation data as years with regression analysis. Data from 1970 to 2004 for Turkey and data from 1980 to 2004 for the world and EU were used for the projections. Electricity energy productions have been forecasted up to year 2030. According to the results, it is determined that cubic (R2 = 0.997) and linear (R2 = 0.993) models for projection of the world's and EU's electricity energy generation, respectively, is fitness while the quadratic (R2 = 0.996) model fits for the projection of Turkey's total electricity energy generation and Turkey will have 0.995% of the world's electricity energy generation in 2030, while the EU will have 8.41% within the world's electricity energy generation in 2030 if the current trend continues.

Karsli, Orhan; Caran, Şemsettin; Dokuz, Abdurrahman; Çoban, Hakan; Chen, Bin; Kandemir, Raif
The Eastern Pontides is characterized by the many of intrusive bodies formed throughout the late Mesozoic-early Cenozoic. Most of these are I-type granitoids, but here, we present for the first time an A-type pluton from the region to assess source characteristics and geodynamic implications. The A-type Pirnalli pluton has a SHRIMP zircon U-Pb age of 81.2±1Ma. It is composed of granite, syenite and quartz monzonite, and its enclaves are monzonitic in composition with elevated Ga/Al ratios and low Mg# (<42). The pluton is dominantly metaluminous (A/CNK=0.88 to 1.00) and belong to shoshonitic and ultra-potassic series. The samples are highly enriched in LREE and show significant negative Eu (Eu/Eu *=0.33 to 0.92), Ba, Nb, Sr and Ti anomalies in the spidergrams. The host rocks and their enclaves posses quite similar Sr-Nd isotopic compositions (I Sr=0.70693 to 0.70736, ε Nd (81Ma)=-2.6 to -2.0, T DM=0.94 to 1.12Ga), pointing to a lower crustal parental magma with a minor contribution of lithospheric mantle. We hypothesize that upwelling of asthenosphere triggered melting of chemically enriched upper mantle and basic magma formed. Melting of lower crust was provided by the underplating of this basic magma. Mixing between lower crust- and mantle-derived melts at depths of lower crust appears to be most reasonable petrogenetic process responsible for generation of the pluton. Sr-Nd isotope modeling suggests mixing of 82-90% of the lower crustal-derived melt with ~10-18% of the mantle-derived melt. Then the hybrid melt ascended to shallower crustal level and underwent a limited fractionation process to generate a variety of rock types. Our data also suggest that the A-type Pirnalli pluton likely formed at an extensional environment of active continental margin throughout the late Cretaceous. Ongoing extension then led to opening of Black Sea as a back-arc basin further north of the Eastern Pontides.

The benefits of taking of aspirin, clopidogrel, and warfarin in relation to cardiovascular mortality and re-hospitalization in chronic heart failure (HF) patients have been called into question. We examined the outcomes (cardiac mortality and/or HF re-hospitalization) in patients discharged from our hospital between January 2003 and July 2009 after hospitalization for chronic decompensated HF. Of 580 HF patients (mean age, 63 ± 13 years; mean ejection fraction, 26 ± 9%, 63% with coronary disease and 37% without coronary disease), 207 patients (36%) died due to cardiovascular reasons, and 313 (54%) required HF re-hospitalization for decompensated HF during a 39 ± 14 month follow-up period. 101 (17%) patients were taking clopidogrel during enrollment in the study. When comparing patients who were on clopidogrel treatment with those who were not, clopidogrel was found to have a beneficial effect on cardiac mortality (27 vs. 38%, P = 0.04). In conclusion, in this observational prospective study, patients who used clopidogrel showed decreased cardiac mortality [HR, 0.566 (95% CI 0.332-0.964), P = 0.036] compared to patients who did not take clopidogrel. Clopidogrel had a beneficial effect on the survival of chronic HF patients in the long term.
