Abstract
OBJECTIVES Colistin is a vital antibiotic used in multidrug-resistant infections. Its most important side effect is nephrotoxicity. Colistin is a weak acid. This study aims to evaluate whether urine alkalinization is protective in the nephrotoxicity of colistin. METHODS Twenty-eight male Sprague-Dawley rats were divided into groups. Group I (n = 4) was injected with intramuscular distilled water twice a day for 7 days. Group II (n = 8) was injected with 750,000 IU/kg/day colistin for 7 days. Group III (n = 8) was injected with the same dose of colistin after their urinary pH was ≥7 through the addition of bicarbonate in their drinking water. Group IV (n = 8) was injected with the same dose of colistin after their urine density fell below 1010 through the addition of NaCl molds in their food and 12.6 mg/L NaCl in their drinking water. RESULTS According to tubular degenerations (scored 0-5), group I scored 0, group II scored 4.25, group III scored 2, and group IV scored 1.5. In groups III and IV, protection was achieved (p = 0.001). The bicarbonate group was not superior to the NaCl group (p = 0.789). In transmission electron microscopy, group III had more microvilli integrity and autophagic vacuoles compared to group IV. Group IV had mitochondrial swelling and cristae lysis. A lower urine density was related to lower tubular scores (p = 0.001). CONCLUSIONS Colistin was highly nephrotoxic without protection. Light microscopy findings revealed that urinary alkalinization and NaCl hydration were similarly protective. Urine alkalinization further prevents ultrastructural changes as revealed by electron microscopy.

Abstract
INTRODUCTION Lifestyle modification is an important component of the secondary prevention strategies; and a healthy diet is one of the cornerstones in management of the coronary heart disease. We aimed to investigate the dietary habits of the patients with history of coronary revascularization, characteristics of the ones with good adherence by using alternate MedDiet questionnaire. METHODS We included outpatients who had a history of coronary revascularization at least 6 months prior to enrollment. Each participant filled out a questionnaire to collect the data of demographics and clinical characteristics. Alternate MedDiet score was calculated to evaluate the Mediterranean style dietary adherence. Alternate MedDiet was originally based on 14-item questionnaire; we adjusted it to our population (max 13 points). RESULTS We enrolled 226 consecutive outpatients (age 61.7±10.9 years, 72% males). The median duration after revascularization was 60 months. A total of 112 (49.6%) patients had previous percutaneous coronary intervention (PCI), 77 (34.1%) had coronary by-pass graft surgery (CABG), and 36 (15.9%) had both revascularization procedures. The median MedDiet score was 6. Patients were stratified into two subgroups (MedDiet score ≥7 vs. <7). A total of 61 (26.9%) patients had MedDiet score ≥7. By univariate analysis, good MedDiet scores were associated with older age, waist circumference, body mass index, high education level, regular follow-up, duration after first revascularization and revascularization with CABG+PCI. In the multivariate analysis, high education level (P=.002, OR=8.212, 95%CI: 2.155-31.291) and duration after revascularization (P=.034, OR=1.007, 95%CI: 1.001-1.013) were independent predictors of good MedDiet scores. CONCLUSION The adherence rate to a healthy diet was low in patients with previous coronary revascularization. MedDiet score seems to be practical and useful item to evaluate the dietary habits in outpatient setting. Mediterranean diet adherence rates were associated with high education level, and duration after revascularization.

Abstract
AbstractThe aim of this study is to determine uranium (238U), potassium (40K) and thorium (232Th) in the radioactive elements by measuring the natural rocks in the vicinity of Antalya province by using High-purity Germanium (HPGe) Detector with gamma spectrometry 69. At the end of the measurements, total absorbed dose rates of the rock samples have been found to be within the normal range of values between 3.10 nGy/h and 117.35 nGy/h. While the minimum value of Raeq has been determined to be 6.36 Bq/kg at sample S8, the maximum value has been determined as 250.15 Bq/kg at sample S4. All of the values obtained at the end of the study have been determined to be lower than the maximum Raeq value (370 Bq/kg) and the limit values for industrial products which ranges between 370 – 740 Bq/kg. ARa, ATh and AK; 232Th, 40K and 226Ra of radionuclides are the activity concentrations in terms of Bq/kg. The hex value should be less than 1. The value is based on the upper limit of Raeq (370 Bq/kg). All of the results obtained are less than the limit value of 1.

Abstract
The Culex pipiens mosquito complex is a group of evolutionarily closely related species including C. pipiens and Culex quinquefasciatus, both infected by the cytoplasmically inherited Wolbachia symbiont. A Wolbachia-uninfected population of C. pipiens was however described in South Africa and was recently proposed to represent a cryptic species. In this study, we reconsidered the existence of this species by undertaking an extensive screening for the presence of Wolbachia-uninfected C. pipiens specimens and by characterizing their genetic relatedness with known members of the complex. We first report on the presence of Wolbachia-uninfected specimens in several breeding sites. We next confirm that these uninfected specimens unambiguously belong to the C. pipiens complex. Remarkably, all uninfected specimens harbour mitochondrial haplotypes that are either novel or identical to those previously found in South Africa. In all cases, these mitochondrial haplotypes are closely related, but different, to those found in other C. pipiens complex members known to be infected by Wolbachia. Altogether, these results corroborate the presence of a widespread cryptic species within the C. pipiens species complex. The potential role of this cryptic C. pipiens species in the transmission of pathogens remains however to be determined. The designation 'Culex juppi nov. sp.' is proposed for this mosquito species.

Abstract
Multimaterial additive manufacturing or three-dimensional (3D) printing of hydrogel structures provides the opportunity to engineer geometrically dependent functionalities. However, current fabrication methods are mostly limited to one type of material or only provide one type of functionality. In this paper, we report a novel method of multimaterial deposition of hydrogel structures based on an aspiration-on-demand protocol, in which the constitutive multimaterial segments of extruded filaments were first assembled in liquid state by sequential aspiration of inks into a glass capillary, followed by in situ gel formation. We printed different patterned objects with varying chemical, electrical, mechanical, and biological properties by tuning process and material related parameters, to demonstrate the abilities of this method in producing heterogeneous and multi-functional hydrogel structures. Our results show the potential of proposed method in producing heterogeneous objects with spatially controlled functionalities while preserving structural integrity at the switching interface between different segments. We anticipate that this method would introduce new opportunities in multimaterial additive manufacturing of hydrogels for diverse applications such as biosensors, flexible electronics, tissue engineering and organ printing.

Abstract
Levosimendan is a calcium sensitizer that demonstrates enhanced myocardial contractility. There is little information concerning the effect of levosimendan on left ventricular tissue parameters and exercise capacity. We evaluated the effects of a 24-h course of levosimendan therapy on cardiac tissue parameters in 30 patients, aged 48-70 years, admitted to our hospital for the management of decompensated heart failure. All patients underwent echocardiographic examination using tissue Doppler imaging (TDI) and a 6-min walk test. Systolic myocardial velocity of the mitral annulus (Sm) was significantly increased in levosimendantreated patients compared with placebotreated patients. There was a positive correlation between Sm and exercise capacity. Levosimendan might be expected to increase cardiac contractile force, especially Sm velocity, in parallel with exercise tolerance. The study has also shown that the progress of ventricular function after levosimendan treatment in patients with exercise intolerance could be monitored effectively by Sm velocity measurements using TDI.

Abstract
Acetylcholine (ACh) is a central neurotransmitter that is used for signal transmission among neurons. For signal transmission in neurons, a neurotransmitter must bind to its receptor in order to produce an action potential. It is known that in Myasthenia Gravis (MG) cases, autoantibodies could block this binding. In the future, the treatment of MG could be achieved via modulation of molecular interaction between ACh and acetylcholine receptor (AChR). This study suggests that if an atom on a ligand (i.e. a neurotransmitter) is replaced with its isotope, it may cause charge redistribution such as that the binding between ligand and its receptor may be improved. Hence suggesting that with replacement of atoms with their isotopes in any biologically important ligand could alter its affinity towards its corresponding receptor, which would have a wide array of applications in medicine.

Abstract
For patients with type I diabetes, transition from pediatric to adult care is a challenge due to complex treatment requirements and the physical, psychological and social changes of adolescence. Members of the care team must recognize that while these emerging adults need to develop self-management skills, this may conflict at times with the developmentally appropriate desire for increasing autonomy. The role of nursing in coordinating a successful transition is critical for maintaining continuity of patient-centered care that responds to the specific needs of these young adults.
