Ali Eman, Serbülent G?khan Beyaz, Hasan Salam, Mustafa Emre Gürcü
Open Journal of Urology (OJU) , 2012, DOI: 10.4236/oju.2012.223031
Abstract: Prostate cancer is the most common urogenital malignity of western communities and is the second leading cause of cancer-related deaths in this population. Pain is often due to bone metastasis in prostate cancer. For the patient diagnosed with cancer and for his family, pain is the most feared aspect of cancer following the likelihood of failure to treat and death. Quality of life is severely impaired together with complaint of pain which arises high rates as 80% in advanced stage cancers.

Open Journal of Urology (OJU) , 2012, DOI: 10.4236/oju.2012.223029
Abstract: Purpose: To investigate electrocardiogram (ECG) changes after complete androgen blockade (CAB) achieved by either surgical or medical castration and compare the outcomes of the groups. Methods: Sixty-three consecutive men (between 58 - 86 years of age) requiring CAB for prostate cancer were enrolled in the study. Patients with diabetes mellitus, an additional malignancy, coronary heart disease, atrial fibrillation, heart failure or a medical history of cardiac event in the last 12 months were excluded from the study. Additionally, those who were taking medicine affecting heart rate were excluded. The participants were divided into two groups according to their modality of castration. The first group consisted of 35 patients who received bilateral orchiectomy plus anti-androgen medication. The second group contained 28 patients who accepted gonadotropin-releasing hormone (GnRH) plus anti-androgen therapy. After complete examinations and biochemical tests, the ECG leads of the patients were obtained conveniently. This was then repeated at three- and six-month visits. ECG findings (including heart rate, PR, QRS, QT, corrected QT (QTc) intervals and QT dispersion (QTd)) were recorded and analysed statistically. The groups were then compared in terms of pre- and post-treatment ECG outcomes. Results: Both groups revealed similarly lower heart rate and prolonged PR, QRS, QT, corrected QTc and QTd by the end of six months. By the end of three months, all variables had changed significantly in the orchiectomy group, whereas in the GnRH group, they had not. Conclusion: CAB may result in lower heart rate and prolonged QT, a condition associated with fatal cardiac arrhythmia and sudden death. Therefore, patients receiving CAB should be monitored closely for cardiac adverse effects.

Abstract: Purpose. We have investigated the effect of haemolysis on free and total prostate-specific antigen (PSA) in daily clinical practice. Materials and Methods. Thirty-nine consecutive men were enrolled in this study. With an 18 gauge (G) needle 4?cc of blood samples were drawn from the right arm and 2?cc of it was expelled gently in a Vacutainer for regular PSA assay and the remaining was emptied into a second tube for complete haemolysis. Simultaneously 2?cc of more blood were taken with a 26?G insulin needle from the left arm of the same patient and expelled into another Vacutainer with forcing. All three samples were assayed for free PSA (fPSA), total PSA (tPSA), and potassium (K). Results. The results of the first tube were fPSA 0,535?ng/mL; tPSA 2,493?ng/mL; K+ 4,178?mmol/L. The results from the haemolysis tube were 0,170?ng/mL; 0,929?ng/mL; 39,545?mmol/L for fPSA, tPSA, K+, respectively, ( value was 0,001 for all the changes). In the same order the third tube results were 0,518?ng/mL, 2,322?ng/mL, and 7,11?mmol/L. Conclusions. Haemolysis may result in interference by decreasing free and total PSA falsely in daily blood draw practice, that could lead to misinterpreting the case in which especially small amount of increase may be of value. 1. Introduction Discrimination between benign and malignant conditions of the prostate has been made mainly by using digital rectal examination and PSA elevation, and a suspected malignancy has been confirmed by biopsy of the prostate due to poor specific and sensitive properties of PSA. PSA and its derivatives, although having some limitations, have been extensively used in prostate cancer detection, staging, and followup of the patients after treatment [1, 2]. While it has also been a subject of an extensive debate in diagnosis and screening the prostate cancer, followup of the patients was achieved with less debate by use of PSA and its derivatives [3–5]. Management of cases may be apparent provided that PSA levels are markedly over or below the cutoff value, but the state that PSA values are around the cutoff value has been a challenge for urologists [6, 7]. In such conditions little changes of PSA or its derivatives, produced by hidden factors related to either biological variation of PSA or laboratory analysis, may have inevitable effect on selecting patients for prostate biopsy [8, 9]. Herein, we present a study about probable effects of blood draw method on free and total PSA to investigate if blood collection method is of value in clinical practice. 2.

Students’ performance awareness, motivational orientations and learning strategies in a problem-based electromagnetism course
Asia-Pacific Forum on Science Learning and Teaching , 2010,
Abstract: This study aims to explore problem-based learning (PBL) in conjunction with students’ confidence in the basic ideas of electromagnetism and their motivational orientations and learning strategies. The 78 first-year geology and geophysics students followed a three-week PBL instruction in electromagnetism. The students’ confidence was assessed through a diagnostic test on electromagnetism. The Motivated Strategies for Learning Questionnaire (MSLQ) was used to identify students’ motivational orientations and learning strategies. The results indicate that many students were confident in incorrect answers, and had inadequate use of cognitive and metacognitive learning strategies. Providing students with some formative assessments during the PBL process could help them to better judge their understanding, which, in turn, would result in better student calibration (i.e., students would be more confident in their correct answers, and less confident in their incorrect answers) in electromagnetism. Helping the first-year PBL students to obtain effective cognitive and metacognitive learning strategies early in the academic year could improve their understanding of physics concepts.
A study of a scale for the level of conscious consumerism
Halil ?brahim Salam
International Journal of Human Sciences , 2010,
Abstract: The purpose of this study is to develop a valid and reliable scale for measuring the levels of conscious consumerism of primary school students. The sample of the study is comprised of 113 4th grade students during the Educational Year 2009/2010 from a state school located in Sakarya, Turkey. For validity purposes, learned opinion was received for face validity and content validity. An exploratory factor analysis was conducted for construct validity. At first, values from the KMO and Barlett tests were taken into account in order to carry out a factor analysis. Since KMO test suggested a variance of .73 and Barlett Sphericity test a meaningful variation (χ2=480.64, p=.000), it was decided that it would be appropriate to conduct a factor analysis for the scale. During the exploratory factor analysis, the items 11, 12, 13, 22 and 23 were excluded from the scale since they distorted the construct. Afterward, a second factor analysis was conducted on the 19-item scale. The exploratory factor analysis concluded that the scale had a three-factor construct and was comprised of a total of 19 items. An overall look at the 19-item scale indicated that it accounted for 40.5 percent of the total variance and inner consistency coefficient was .77. All these values suggest that the scale is a valid and reliable one.

Uluslararas? Türk?e Edebiyat Kültür E?itim Dergisi , 2013, DOI: http://dx.doi.org/10.7884/teke.157
Abstract: Mahtumkulu, recognized as the greatest poet of Turkmen literature, was born in the 1724 and passed away in the 1807. His father, D vletmemmet Azadi (1700-1760), is one of the prominent representatives of Turkmen literature of the 18th century. Mahtumkulu was a poet and social leader who was not indifferent to the social problems of his era and tried to lead and give hope to his society. The poems of Mahtumkulu cover all aspects of Turkmen way of life. He was the voice of his people. Turkmen union, Turkmen spirit and consciousness, religion and Sufism, the comparison of good person and bad person, criticism of the individual and society, social justice, love, bad habits, education, helpfulness, and advice were the main themes of his poems. In this study, Mahtumkulu’s approach to the society and individuals, who make the society, will be addressed through his critical poems.Türkmen edebiyat n n en büyük airi say lan Mahtumkulu 1724 y l nda do mu , 1807 y l nda da vefat etmi tir.

Abstract: AIM: To investigate the effects of gallbladder stones on motor functions of the gallbladder and the dynamics of bile flow in asymptomatic gallstone disease.METHODS: Quantitative hepatobiliary scintigraphy was performed to detect the parameters of gallbladder motor function [gallbladder ejection fraction (GBEF), gallbladder visualization time (GBVT), gallbladder time to peak activity (GBTmax), gallbladder half emptying time (GBT1/2), and transit time of bile to duodenum (TTBD)] in 24 patients with asymptomatic cholelithiasis who were diagnosed incidentally during routine abdominal ultrasonographic examination and 20 healthy subjects with normal gallbladder.RESULTS: Even though there was no significant difference in the clinical and laboratory parameters between the patient and control groups, all parameters of gallbladder function except TTBD were found to differ significantly between the two groups. GBEF in the patient group was decreased (P = 0.000) and GBVT, GBTmax, GBT1/2 in the patient group were longer (P = 0.000, P = 0.015, P = 0.001, respectively).CONCLUSION: Our results showed that even if there were not any clinical and laboratory findings, gallbladder filling and emptying could be impaired in patients with gallstone disease.

Open Journal of Optimization (OJOp) , 2015, DOI: 10.4236/ojop.2015.43008
Abstract: We analyze a Coxian stochastic queueing model with three phases. The Kolmogorov equations of this model are constructed, and limit probabilities and the stationary probabilities of customer numbers in the system are found. The performance measures of this model are obtained and in addition the optimal order of service parameters is given with a theorem by obtaining the loss probabilities of customers in the system. That is, putting the greatest service parameter at first phase and the second greatest service parameter at second phase and the smallest service parameter at third phase makes the loss probability and means waiting time minimum. We also give the loss probability in terms of mean waiting time in the system.\"\" is the transition probability from j-th phase?to?\"\"?phase \"\" . In this manner while \"\" and \"\" this system turns into \"\" queueing model and while \"\" the system turns into Cox(2) queueing model. In addition, loss probabilities are graphically given in a 3D graph for corresponding system parameters and phase transient probabilities. Finally it is shown with a numeric example that this theorem holds.
