Doxorubicin (DOX) cardiotoxicity is a significant side effect in cancer survivors. DOX and its metabolites alter cardiac gene expression and affect metabolic energy-related peptides. Adropin, copeptin, irisin and TRPM2 are produced locally in the heart and play a role in energy homeostasis. We investigated the fates of adropin, copeptin, irisin and TRPM2 in serum and cardiac tissues of DOX treated rats. Animals were divided into three groups of six: 1) untreated controls, 2) DOX treated and 3) saline treated. The rats were fed a standard diet ad libitum for 14 days then were sacrificed and heart and serum samples were taken. Adropin, copeptin, irisin levels in tissue homogenates and serum were measured using ELISA. Immunoreactivity of heart tissue adropin, copeptin, irisin and TRPM2 also were investigated. The peptides increased in both serum and cardiac tissue homogenates in animals treated with DOX compared to the other groups. DOX increased adropin in endocardial and myocardial cells, but it decreased expression of copeptin. DOX did not affect endocardial irisin and TRPM2 expressions, but myocardial irisin and TRPM2 expressions were increased. Serum adropin, irisin and copeptin were increased in DOX treated rats. Cardiac adropin, copeptin, irisin and TRPM2 are affected by DOX and may play a role in DOX cardiotoxicity.

PurposePrimary dysmenorrhea (PD) is a common cause of pelvic pain that can cause limitations in daily activities. Treatment options sometimes result in failure, suggesting that different mechanisms may be effective in etiopathogenesis. Eosinophils are cells that are present in endometrium only in the perimenstrual period. The aim of this study was to evaluate the levels of eotaxin, a potent eosinophilic chemoattractant, in patients with PD.Patients and methodsThirty patients with PD and thirty healthy women were included in the study. Venous blood sample of 10 mL was collected from each participant. Blood samples were taken in the first 2 days of the menstrual cycle at any period of the day. Serum eotaxin levels were determined by enzyme-linked immunofluorescence assay.ResultsThere were no statistically significant differences between the demographic properties of groups in terms of age and body mass index. Eotaxin levels were significantly different in patients with PD than the control subjects (p=0.012).ConclusionDetection of different levels of eotaxin in patients with PD may be a new and important step in determining the factors contributing to the pathogenesis of dysmenorrhea.

Background and Aims. Pulmonary thromboembolism (PTE) is a frequent disease with difficult diagnosis and high mortality. Misdiagnosis occurs in 2/3 patients and mortality rates reach up to 30%. The aim of our study was to investigate the role of adiponectin used in emergency service in diagnosis of PTE. Materials and Methods. 95 patients with suspected PTE included in the study. Plasma adiponectin and D-dimer levels were measured and chest X-ray and multidetector row computed tomography scan obtained. Diagnosis was supported by vascular filling defect on tomography. Control group consisted of patients with suspected PTE and normal chest computed tomography findings. Results. Mean D-dimer level was 4241.66 ± 1082.98 ng/mL in patients and 2211.21 ± 1765.53 ng/mL in the control group (p ≤ 0.05). Mean adiponectin level was 5.46 ± 4.39 μg/mL in patients and 7.68 ± 4.67 μg/mL in the control group (p ≤ 0.05). Wells and Geneva scores were higher in patients compared to the control group. Conclusions. As a result, we conclude that lower adiponectin levels have an important role in the diagnosis of PTE.
