Item Assessments Regarding the Legal Status of Afghans Who are Irregular Migrants in Turkey(2022) Koca, Sema Cortoglu; IZP-7037-2023In this study, the legal statuses of Afghans who are irregular migrants in our country, due to the events in Afghanistan, have been explored. To begin with, it has been attempted to determine which of the international protection types such as refugee, conditional refugee and subsidiary protection statuses can or cannot be obtained, as well as the examples of judicial decisions. The international protection application procedure has also been discussed while making this determination. When the international protection applicants and international protection status holders in Turkey are examined, it is discovered that the majority of these groups are Afghans. The issues to be considered in the individual evaluations of the administration in terms of each applicant while granting international protection status are also discussed. Moreover, regarding the evaluations made in terms of the applicant, the decisions of the European Court of Human Rights and the Turkish court decisions are included. Our study has also evaluated whether Afghan citizens can get temporary protection status and immigrant status. Citizens of the Syrian Arab Republic who came to or crossed our borders from Syria for temporary protection as a result of the events in Syria have been granted temporary protection. In our study, the case in which it is possible to grant Afghan citizens temporary protection has been evaluated. Moreover, it has been discussed whether it is possible to grant immigrant status to Afghan citizens of Turkish origin in the past. Finally, in the study, the types of residence permit that Afghan citizens who are irregular immigrants in the country can obtain in order to legally reside in Turkey are mentioned.Item How to Approximate Cosine Curve with 4(Th) and 6(Th) Order Bezier Curve in Plane?(2022) Kilicoglu, Seyda; Yurttancikmaz, SemraThere are many ways to approximate cosine curve. In this study we have examined the way how the cosine curve can be written as any order Bezier curve. As a result using the Maclaurin series we have examined cosine curve as the 4(th) and the 6(th) order Bezier curve based on the control points with matrix form in E-2. We give the control points of the 4(th) and the 6(th) order Bezier curve based on the coefficients. Also we give the coefficients based on the the control points of the 4(th) and the 6(th) order Bezier curve too.Item Ticaret hukukunda güncel gelişmeler(2016) Güven, KudretItem Long-Term Oral Nutrition Supplementation Improves Outcomes in Malnourished Patients With Chronic Kidney Disease on Hemodialysis(2014) Sezer, Siren; Bal, Zeynep; Tutal, Emre; Uyar, Mehtap Erkmen; Acar, Nurhan Ozdemir; 24436491Background: There is no consensus on the type, time of initiation, or duration of use of enteral nutrition in patients with chronic kidney disease (CKD). This study aimed to compare the effects of a renal-specific oral nutrition supplement (RS-ONS) and a standard recommended nutrition regime on biochemical and nutrition markers in malnourished patients with CKD on hemodialysis. Methods: Sixty-two malnourished patients with CKD, divided into experimental (RS-ONS; n = 32; mean [SD] age, 62.0 [11.3] years; 55.2% female) and control (CON; n = 30; mean [SD] age, 57.2 [12.3] years; 31% female) groups, were evaluated for anthropometric, biochemical, and inflammatory parameters. Results: Mean (SD) serum albumin levels were significantly increased in the RS-ONS group from 3.5 (0.3) g/dL at baseline to 3.7 (0.2) g/dL at 6 months (P = .028). Significantly fewer patients had serum albumin levels of <3.5 g/dL after month 6. Dry weight of patients significantly increased in the RS-ONS but decreased in the CON groups (P < .001 for each). Percent change from baseline revealed negative results for bioelectrical impedance analysis (P < .001) in the CON group. Malnutrition inflammation score at 6 months (P = .006) and erythropoietin (EPO) dose requirements were higher in the CON group (P = .012). Conclusions: Our findings indicate that consuming RS-ONS improves serum albumin and anthropometric measures, as well as reduces EPO dose, in patients with CKD.Item New-Onset Diabetes and Glucose Regulation Are Significant Determinants of Left Ventricular Hypertrophy in Renal Transplant Recipients(2015) Sezer, Siren; Uyar, Mehtap Erkmen; Tutal, Emre; Bal, Zeynep; Guliyev, Orhan; Colak, Turan; Hasdemir, Efe; Haberal, Mehmet; 25945353Background. New-onset diabetes after transplantation (NODAT) is associated with decreased graft survival and an increased risk for cardiovascular disease. The objective of this study was to evaluate the risk factors for development of NODAT and its' relationship with arterial stiffness and left ventricular mass index (LVMI) in kidney transplant recipients. Methods. 159 kidney transplant recipients were selected from our transplantation center who underwent renal transplantation between years 2007 and 2010. Results. Among 159 patients, 57 (32.2%) patients were with NODAT who were significantly older than patients without diabetes (P: 0.0001). Patients with NODAT had significantly higher pulse wave velocity (PWv) (P: 0.033) and left ventricular mass index LVMI (P: 0.001) compared to patients without NODAT. Further analysis was done according to LVMI as follows: LVMI > 130 g/m(2) (n: 57) and LVMI <= 130 g/m(2) (n: 102). We observed higher office systolic and diastolic BP, serum trygliceride, glucose, creatinine, age, and HbA1c (P: 0.0001) levels in patients with LVMI > 130 g/m(2). Linear regression analysis revealed that HbA1c was the major determinant of LVMI (P: 0.026, beta: 0.361). Conclusions. HbA1c is the major determinant of LVMI, so strict control of serum glucose levels is essential for preventing cardiovascular disease in patients with NODAT.Item Balloon Dilatation of Iatrogenic Ureteral Strictures after Upper Urinary Tract Reconstruction(2015) Duman, Enes; Yildirim, Erkan; Akillioglu, Ishak; Yucesan, SelcukPurpose: Open pyeloplasty is the gold standard treatment of uretero-pelvic junction (UPJ) stenosis. Although failure after open pyeloplasty or uretero-neosistosmy is not common, percutaneous or endoscopic interventions must be necessary in some cases. We present treatment of 6 pediatric patients by balloon dilatation after failed surgery. Material and Methods: Between 2008 and 2013 6 children were treated. Five patients had undergone open pyeloplasty for UP stenosis and, one has uretero-vesical anastomosis stricture after ureteroneosistostomy. Percutaneous antegrade balloon dilatation and double J stent placement were performed in three of six patients. In the other three patients retrograde endoscopic balloon dilatation and double J stent placement were performed. Results: Primary technical success was %50 and %100 for antegrade and retrograde approach respectively. Antegrade approach has failed in 3 patients (%50) and, retrograde approach and treatment were successful in all of these patients. Secondary and tertiary balloon dilatations were done through antegrade approach in 3 patients. Mean duration of double J stent was 114 days. As of today, five patients are followed smoothly. One patient who has UP stenosis underwent secondary open surgery. Conclusion: Balloon dilatation can be used safely in both antegrade and retrograde approaches because of lower profile of balloon catheters, so it could be considered as a first line treatment option after failed surgical treatment of upper urinary tract stenosis in children.Item Effect of the Bioadhesive, BioGlue, on Impaired Colonic Anastomose Healing in Rats(2015) Ekici, Yahya; Akcay, Eda Yilmaz; Moray, GokhanColonic anastomotic leakage is still a problem in general surgery practice. We sought to investigate the effect of a new tissue adhesive, BioGlue, on the healing of normal and impaired colonic anastomoses. Sixty-four rats were randomized into 4 groups. In all animals, a 1-cm segment of the left colon was resected, and an end-to-end sutured anastomosis was created. Animals were then divided into 2 groups: normal and impaired anastomosis. These 2 groups were further subdivided into 2 additional groups: animals that received BioGlue and those that did not. All rats received intraperitoneal injections of either 0.9% NaCl or 5-fluorouracil (5-FU). Anastomotic evaluation was done 7 days after surgery. Macroscopic healing, mechanical strength, and histopathologic healing parameters were evaluated. Leakage of the anastomosis was significantly higher in rats in the impaired group compared with those in the BioGlue groups (P = 0.043). The adhesion formation score was significantly higher in rats in the impaired anastomosis group compared with the other groups. Bursting pressures were significantly lower in the impaired anastomosis group than in the other ones (P = 0.001). Neoangiogenesis and fibroblast activity were different among the groups (P = 0.001). Inflammatory cell infiltration and collagen deposition did not differ among the groups (P = 0.07). Immediate postoperative intraperitoneal administration of 5-FU after colonic anastomosis inhibits intestinal wound healing. Covering colon anastomoses with BioGlue after suturing conferred beneficial effect on healing.Item Evaluation of peripheral perfusion in term newborns before and after Yintang (EX-HN 3) massage(2015) Tugcu, Ali Ulas; Cabioglu, Tugrul; Abbasoglu, Aslihan; Ecevit, Ayse; Ince, Deniz Anuk; Tarcan, Aylin; 26742308OBJECTIVE: To identify how acupressure on the acupoint Yintang (EX-HN 3) impacts oxygen saturation, pulse rate, and peripheral perfusion in term-born infants without underlying disease. METHODS: Infants born between weeks 37 and 42 of gestation were included in this study. The polyclinic's neonatology room was noise-controlled and made half-dark to prevent the perfusion index from being confounded. A pulse oximeter was linked to the baby's left lower extremity. Acupressure was applied on Yintang (EX-HN 3) for 30 s clockwise, held for 30 s, and then acupressure was applied for another 30 s counterclockwise. The baby's SaO(2), pulse rate, and perfusion index were recorded for each minute before and after acupressure. RESULTS: When pre- and post-acupressure pulse rate values were compared, a significant decrease in pulse rate values after acupressure application was observed. When pre- and post-acupressure oxygen saturation values were compared, a significant increase in post-acupressure oxygen saturation was observed. In addition, peripheral perfusion increased significantly after acupressure. CONCLUSION: Acupressure application has been used in traditional medicine for many years. However, it is not yet widely used in modern medicine. This study shows the impact of acupressure on neonatal skin perfusion, oxygen saturation, and pulse rate. (C) 2015 JTCM.

Material and Method: Forty-six rats were randomized to sham (n=14), control (n=16), silymarin (n=16) groups. Each group had early and late subgroups. Silimarin was administered in the silimarin group and saline was administerd in control and sham groups. Artificial acute pulmonary damage associated with sepsis was provided with caecal ligation-perforation method in control and silimarin groups. Rats in the early subgroup Were terminated at the end of the 12th hour and threats in the late group were followed-up. Serum and bronchoalveolar lavage fluid (BAL) tumor necrosis factor (TNF)-alpha, interleukin (IL)-1beta, and IL-6; lung tissue malondialdehyde (MDA) and glutathione (GSH) levels; lung histopathologic examination; and lung wet-to-dry (w/d) weight ratio measurements were used to compare and evaluate the severity of lung injury between the groups. Results: Mortality rates for silymarin and control groups were 62.5% and 12.5%, respectively (log-rank p=0.0506). Compared with the silymarin group, the control group exhibited significantly more severe lung injury, as indicated by higher mean values for serum and BAL TNF-alpha, IL-1beta and IL-6 (p<0.05 for all measurements), total lung histopathologic injury score (p=0.001), w/d (p=0.019) and lung-tissue MDA (p=0.011) levels. Lung tissue GSH levels were significantly higher in silymarin group than control group (p=0.001). Conclusion: Silymarin reduces the severity of sepsis induced-acute lung injury and may also improve survival in a cecal ligation and perforation rat model. These beneficial effects of this agent are probably due to its inhibitory effects on inflammatory process and oxidative injury.Item Association between treatment with coil embolization of renal artery aneurysm and resistant hypertension(2016) Duman, Enes; Yildirim, Erkan; Ciftci, Ozgur; Cifci, EgemenHypertension is the number one risk factor in preventable causes of death in the world. Resistant hypertension is defined as blood pressure that remains uncontrolled despite at least three antihypertensive medications including a diuretic. Treatment of hypertension includes many modalities from lifestyle changing to multiple drug using, angioplasty. In this case report, we aim to emphasize the effects of renal artery aneurysm treatment on resistant hypertension.
