Abstract
Objective: Immaturity of the digestive tract and enteric nervous system is a widely accepted theory for infantile colic (IC) etiopathogenesis. The study aimed to show whether neurotrophins that are necessary for normal functioning and development of the gastrointestinal system have a role in the pathogenesis of IC. Materials and Methods: The IC group (n = 75) comprising the mothers of infants with IC and the control group (n = 75) were included to this cross-sectional case-control study. Brain-derived neurotrophic factor (BDNF), glial cell-derived neurotrophic factor (GDNF), ciliary neurotrophic factor (CNTF), and nerve growth factor (NGF) levels of breast milk samples were evaluated by immunosorbent analysis method. Results: The mean age of infants with IC was 7.3 ± 2.8 weeks, while the mean age of the control group was 8.1 ± 2.9 weeks (p = 0.110). No significant difference was found between the breast milk BDNF, GDNF, CNTF, and NGF levels of two groups (p = 0.941, p = 0.510, p = 0.533, p = 0.839, respectively). Conclusions: This is the first report comparing the neurotrophin levels of the breast milk samples taken from the mothers of infants with and without IC. The study demonstrated that breast milk neurotrophin levels of the mothers did not differ significantly between the infants with and without IC.

Abstract
INTRODUCTION We aimed to investigate serum galanin-like peptide (GALP) levels and their correlation with hormonal and metabolic parameters in patients with polycystic ovary syndrome (PCOS). MATERIAL AND METHODS The study included 48 women (age range, 18-44 years) with a diagnosis of PCOS, and a control group that included 40 healthy females (age range, 18-46 years). Waist circumference, body mass index (BMI), and Ferriman-Gallwey score were evaluated and plasma glucose, lipid profile, oestradiol, progesterone, total testosterone, prolactin, insulin, dehydroepiandrosterone sulphate (DHEA-S), follicle-stimulating hormone (FSH), luteinizing hormone (LH), thyroid-stimulating hormone (TSH), 25-hydroxyvitamin D (25(OH)D), fibrinogen, d-dimer, C-reactive protein (CRP), and GALP levels were measured in all study subjects. RESULTS Waist circumference (p = 0.044) and Ferriman-Gallwey score (p = 0.002) were significantly higher in patients with PCOS compared to the control group. Among the metabolic and hormonal parameters studied, only total testosterone was significantly higher in patients with PCOS (p = 0.002). Also, the serum 25(OH)D level was significantly lower in the PCOS group (p = 0.001). CRP, fibrinogen, and D-dimer levels were all similar between the 2 groups. Serum GALP level was significantly higher in PCOS patients (p = 0.001). GALP was negatively correlated with 25(OH)D (r = -0.401, p = 0.002) and positively correlated with total testosterone values (r = 0.265, p = 0.024). Multiple regression analysis revealed that both total testosterone and 25(OH)D significantly contributed to GALP levels. CONCLUSIONS Our study is the first in the literature to evaluate serum GALP levels in patients with PCOS. Increased GALP levels in PCOS and its association with total testosterone levels might show that GALP can act as an intermediary in increased GnRH-mediated LH release, which is one of the underlying pathogenetic mechanism of PCOS.

Abstract
PURPOSE Obesity, a low-grade systemic inflammatory disease, causes inflammation in metabolic tissues. Galectin-3(Gal-3) is one of the lectin molecules involved in inflammatory processes. We evaluated the possible relationship between Gal-3 level and the metabolic inflammatory process before and after obesity surgery. METHODS One hundred participants were included in the study and classified as normal weight, overweight, Class I, II, and III obese. Class III obese group underwent bariatric surgery and evaluated in the 3rd and 6th months after surgery. Glucose, insulin, glycated hemoglobin A1c (HbA1c), homeostatic model assessment of insulin resistance (HOMA-IR), high sensitivity C-reactive protein (hsCRP), Gal-3, interleukin (IL)-6, IL-10, adiponectin, and leptin levels were determined. RESULTS Gal-3 levels were higher in Class III obese compared to the normal weight group. Postoperative leptin and hsCRP levels were decreased significantly, but the decrease in IL-6 and Gal-3 levels were not significant. Postoperative increased adiponectin and IL-10 levels were significant. Gal-3 was found significantly higher in insulin resistant group. The correlation between Gal-3 with BMI, adiponectin, leptin, hsCRP levels, and HOMA-IR was found weak. CONCLUSION These findings might support the fact that Gal-3 is one of the molecules involved in the linkage between insulin resistance and meta-inflammation in morbid obese.

Abstract
OBJECTIVES Biological variation is defined as the variation in analytical concentration between and within individuals, and being aware of this biological variation is important for understanding disease dynamics. The aim of our study is to calculate the within-subject (CVI) and between-subject (CVG) biological variations of serum creatinine, cystatin C and Beta trace protein (BTP), as well as the reference change value (RCV) and individuality indexes (II), which are used to calculate the glomerular filtration rate while evaluating kidney damage. METHODS Blood samples were collected from 22 healthy volunteers for 10 consecutive weeks and stored at -80 °C until the day of analysis. While the analysis for serum creatinine was performed colorimetrically with the kinetic jaffe method, the nephelometric method was employed for cystatin C and BTP measurements. All analyses were carried out in a single session for each test. RESULTS Analytical coefficient of variation (CVA) for serum creatinine, cystatin C and beta trace protein was 5.56, 3.48 and 5.37%, respectively. CVI and CVG: for serum creatinine: 3.31, 14.50%, respectively, for cystatin C: 3.15, 12.24%, respectively, for BTP: 9.91, 14.36%, respectively. RCV and II were calculated as 17.94%, 0.23 for serum creatinine, 13.01%, 0.26 for cystatin C, 31.24%, 0.69 for BTP, respectively. CONCLUSIONS According to the data obtained in our study, serum creatinine and cystatin C show high individuality, therefore we think that the use of RCV instead of reference ranges would be appropriate. Although II is found to be low for BTP, more studies are needed to support this finding.

Abstract
C-reactive protein-to-albumin ratio (CAR) has been used as an indicator of prognosis in various diseases. Here, we intended to assess the CAR’s diagnostic power in early differentiation of hospitalized severe COVID-19 cases. In this retrospectively designed study, we evaluated 197 patients in total. They were divided into two groups based on their severity of COVID-19 as non-severe (n = 113) and severe (n = 84). The comparison of groups’ demographic data, comorbidities, clinical symptoms, and laboratory test results were done. Laboratory data of the patients within the first 24 h after admission to the hospital were evaluated. The calculation of receiver operating characteristic (ROC) curve was used to determine the diagnostic power of CAR in differentiating severity of COVID-19. Independent risk factors predictive of COVID-19 severity were determined by using logistic regression analysis. Although lymphocyte count levels were lower, severe COVID-19 patients had higher mean age, higher levels of neutrophil count, CRP, aspartate aminotransferase (AST), ferritin, and prothrombin time (P < 0.05). Compared with non-severe patients (median, 0.23 [IQR = 0.07–1.56]), patients with severe COVID-19 had higher CAR levels (median, 1.66 [IQR = 0.50–3.35]; P < 0.001). Age (OR = 1.046, P = 0.003), CAR (OR = 1.264, P = 0.037), and AST (OR = 1.029, P = 0.037) were independent risk factors for severe COVID-19 based on the multivariate logistic regression analysis. ROC curve analysis assigned 0.9 as the cut-off value for CAR for differentiation of severe COVID-19 (area under the curve = 0.718, 69.1% sensitivity, 70.8% specificity, P < 0.001). CAR is a useful marker in early differentiation of severity in patients hospitalized due to COVID-19 that have longer hospital stay and higher mortality.

Abstract
CA 15-3 is a tumor-associated antigen and is overexpressed in breast tumors, and may also be high in some other non-cancerous conditions. The aim of this study was to investigate the effect of megaloblastic anemia due to vitamin B12 or folic acid deficiency on the levels of tumor markers. Five-year patient data were retrospectively analyzed. The associations between megaloblastic anemia due to vitamin B12 deficiency and CA 15-3, CA 125, CA 19-9, CEA, and AFP levels were analyzed. Furthermore, association between CA 15-3 level and megaloblastic anemia due to folic acid deficiency was evaluated. Median CA 15-3 level was 38.1 U/mL in the group with megaloblastic anemia due to vitamin B12 deficiency(n = 15), 46.7 U/mL in the group with megaloblastic anemia related to folic acid deficiency (n = 3), and 17.8 U/mL in the normal group(n = 1724). CA 15-3 levels were significantly higher among patients with vitamin B12- and folic acid-associated megaloblastic anemia compared to the normal group (p = 0.001 and p = 0.005, respectively). Megaloblastic anemia due to vitamin B12 deficiency was not associated with any significant differences in CA 125, CA 19-9, CEA, or AFP levels compared to the normal group (p = 0.777, p = 0.327, p = 0.577, and p = 0.197, respectively). The numbers of anemic and normal subjects compared in these tests were 12 vs. 1501, 17 vs. 1827, 4 vs. 897, and 8 vs. 1041, respectively. In conclusion, megaloblastic anemia results in ineffective erythropoiesis, and increased levels of CA 15-3 may be associated with this issue. Clinicians should take this into account when evaluating for a pre-diagnosis of breast cancer.

Abstract
BACKGROUND The most common sources of error in the preanalytical phase are considered to be at the stage of patient preparation and sample collection. In order to reduce the preanalytical errors, we aimed to determine the level of phlebotomists knowledge about the preanalytic phase before and after planned trainings in the study. METHODS Training about preanalytical processes was given to the 454 health professionals and the majority of them were employed as nurse. Questionnaires before and after training were conducted. In order to assess the effect of the training into the process, preanalytical error rates were calculated before and after training. RESULTS The total correct answer rates of vocational school of health diplomaed were statistically lower than the total correct answer rates of other. It was observed significantly increase in the rate of correct answers to questionnaire and significantly decrease in preanalytical error rates after training. CONCLUSIONS The results of the survey showed that the attitudes of the phlebotomists were diverse in the preanalytical processes according to the levels of education and their practices. By providing training to all staff on a regular basis, their information about preanalytical phase could be updated and hence, it may possible to significantly reduce the preanalytical errors in health practice and nursing science.

Abstract
INTRODUCTION Although serum-providing blood tubes with a barrier are still widely used due to their significant advantages, the use of blood tubes with a barrier to provide plasma is becoming widespread. We compared 22 analytes in a BD Vacutainer® Barricor LH Plasma tube for local clinical validation of this new lithium heparin tube with a barrier. MATERIALS AND METHODS Samples from 44 volunteers were collected in different tubes (Becton Dickinson and Company): Z tube without additive (reference), clot-activator tube with gel (SST), lithium heparin tube without gel (LiH), and lithium heparin tube with barrier (Barricor). Analyte concentrations in different tubes were compared with the reference tube. All tubes were also evaluated according to additional testing (different centrifugation durations, blood-sampling techniques and individual differences). RESULTS Aspartate aminotransferase (AST), glucose (Glc), potassium (K), lactate dehydrogenase (LD), sodium (Na), and total protein (TP) had a significant bias in Barricor (9.19%, - 3.24%, - 4.88%, 21.60%, - 0.40%, 5.03%, respectively) relative to the reference tube. There was no statistical difference between different centrifugation durations and individual differences for AST, K and LD in LiH and/or Barricor (P > 0.05). There was a significant bias for LD between LiH and Barricor in terms of blood-sampling techniques (21.2% and 12.4%, respectively). CONCLUSIONS Recently, the use of plasma has become prominent due to some of its advantages. In this study, plasma AST, K, LD, Glc and TP levels in Barricor were clinically different in comparison to serum. The results of additional tests showed that higher levels of LD in Barricor did not result from haemolysis, and they might be related to other factors including number of platelets, cellular fragility, or functional environment.

Abstract
INTRODUCTION The incidence of heart failure (HF) has reached epidemic levels in western populations, and the majority of these patients are admitted to hospitals through the emergency department (ED). We aimed to aid clinicians assessing natriuretic peptide (NP) levels in cases with suspected HF. In this study, we investigated the effect of anemia on amino-terminal pro-BNP (NT-proBNP) and on B-type natriuretic peptide (BNP) levels. METHODS This retrospective study examined patients who were admitted to the ED with suspected HF. After admission, the treating physician requested complete blood count and creatinine tests with NT-proBNP (n=2.637) or BNP (n=11.159). The exclusion criteria were used to minimize the factors that could affect the NT-proBNP and BNP results. We examined the data using the Mann-Whitney U test, Chi-square test, Spearman correlation test, and multivariate linear regression analyses. RESULTS The NT-proBNP and BNP levels were statistically higher in the groups with anemia (p=0.016 and p=0.009, respectively). There was a statistically significant negative correlation between hemoglobin and NP levels (r=-0.272, p<0.001 for NT-proBNP and r=-0.179, p<0.001 for BNP). The results indicated that advanced age and low hemoglobin levels were significantly associated with the increase in NT-proBNP (p=0.024 and p=0.004, respectively). Advanced age, low hemoglobin and low GFR-MDRD levels were significantly associated with the increase in BNP (p<0.001, p=0.002 and p=0.013, respectively). DISCUSSION The data suggest that clinicians examining patients admitted to the ED with suspected HF should consider that anemia could lead to increases in NT-proBNP and BNP levels.

Abstract
This experiment was designed to investigate the lipid peroxidation and histological effects of chronic fluorosis on first and second generation rat lung tissues. Sixteen, virgin, female Wistar rats were mated with eight males (2:1) for approximately 12 h to obtain first-generation rats. Pregnant rats were divided into two experimental groups (control and fluoride supplemented). The pregnant rats in the fluoride-supplemented group were exposed to 30 mg/L sodium fluoride (NaF) in commercial drinking water containing 0.07 mg/L NaF throughout the gestation and lactation periods. After the lactation period, young animals (first generation; F1) were exposed to the same amount of NaF in drinking water for four months. At the end of the four-month experimental period, nine randomly-chosen male rats (F1) were sacrificed and lung tissues were removed for histopathological and enzymatic lipid peroxidation examination. The second generation rats were obtained from the remaining rats by the same method. They were also treated similarly. At the end of the four-month experimental period, nine randomly-chosen male rats (F2) were sacrificed, and the lungs were removed for histological and lipid peroxidation examination. The rats in the control groups underwent the same procedure without NaF supplementation. It was found that the plasma fluoride and the lung TBARS levels of fluoride supplemented F1 and F2 rats were higher than controls. There were marked histological changes in the lung tissues of fluoride supplemented F1 and F2 rats, as follows: in F1 rats; loss of alveolar architecture, emphysematous areas, descuamation of alveolar epithelium and alveolar congestion were observed. There were thickened interalveolar septae and congestion of alveolar septal vessels. Intraparenchymal thick-walled vessels were also observed. There were markedly perivascular and intraparenchymal focal mononuclear cell infiltrations. In F2 rats, in addition to these changes, there were lipid cell hyperplasia and increased connective tissue mass in the parenchymal areas. It is concluded that chronic fluorosis causes a marked destruction in lung tissues of F1 and F2 rats by causing lipid peroxidation. Toxicology and Industrial Health 2006; 22: 375-380.

Abstract
BACKGROUND Vitamin D deficiency and a high mean platelet volume (MPV) are related to cardiovascular disease. We investigated whether vitamin D deficiency is associated with high MPV. METHODS This study included 434 patients without chronic disease who were not taking vitamin D or calcium supplements. Vitamin D was measured by chemiluminescent microparticle immunoassay on the Architect-I2000 system (Abbott Diagnostics, USA), and MPV was measured on the Cell-Dyn Ruby analyzer (Abbott Diagnostics). Patients were divided into Groups 1 (138 [men/women, 46/92]), 2 (148 [men/women, 54/94]), and 3 (148 [men/women, 50/98]) according to vitamin D levels of <10 ng/mL, 10-20 ng/mL, and >20 ng/mL, respectively. RESULTS The vitamin D level in Group 1 (7.7±1.9 ng/mL) was lower than that in Group 2 (15.1±1.6 ng/mL, P<0.001) and Group 3 (25.6±6.3 ng/mL, P<0.001). The MPV in Group 3 (7.5±1.0 fL) was lower than that in Group 1 (8.1±1.1 fL, P<0.001) and Group 2 (7.9±1.0 fL, P=0.009). Linear regression analysis showed that low levels of vitamin D (β=-0.109, P=0.019) was independently associated with increased MPV. CONCLUSIONS There was a strong association between a low vitamin D level and a high MPV; therefore, vitamin D deficiency may be associated with increased MPV.

Abstract
The present study investigated the effect of chlorpyrifos on NMDA receptor subunits NR2A and NR2B in juvenile and adult rats. Chlorpyrifos was administered with the dose of 40 and 70 mg/kg to juvenile and adult rats, respectively. Chlorpyrifos significantly inhibited the AChE activity in juvenile and adult rats (p < .05). NR2A and NR2B levels significantly increased in juvenile and adult rats by chlorpyrifos application (p < .05). Increased NR2A and NR2B levels may reflect increased glutaminergic activity, consequently neuronal damage. In the case of neuronal damage, learning and memory could be affected negatively even though NR2A and NR2B increased.
