Can neutrophil-lymphocyte and platelet-lymphocyte ratios predict threatened abortion and early pregnancy loss?

Objectives: An investigation of the importance of hematological inflammatory markers on the prognosis of first trimesterpregnancies and their role in predicting threatened abortion and early pregnancy loss.Material and methods: This study was carried out in the Obstetrics and Gynecology Department of the Faculty of Medicine inour University between January 2018 and May 2019. Three-hundred individuals, 100 of them diagnosed with early pregnancyloss (EPL), 100 diagnosed with threatened abortion (TA) and 100 healthy control patients (HC), participated in the study.Results: There were no statistically significant differences in terms of hemoglobin, platelet, neutrophil count and NLRbetween the three groups. The RBC counts were significantly lower in EPL and TA compared to HC. Similarly, it was determinedthat the MPV value was significantly lower in EPL compared to HC. On the other hand, there was no difference inMPV between TA and HC. The PLR was higher in EPL and TA.Conclusions: MPV, RBCs and PLR values were strongly associated with first-trimester miscarriage. These economical andeasily measurable platelet indices can be used to predict fetal losses

Role of lymphadenectomy in disease-free and overall survival on low risk endometrium cancer patients

Objectives: Evaluation of the effect of lymphadenectomy in disease-free and overall survival on the low risk corpus cancer. Material and methods: Between 1994 and 2012, a total of 257 patients with endometrioid type, grade 1 or 2, myometrial invasion < 1/2, no intraoperative evidence of macroscopic extrauterine spread was treated surgically. Pelvic lymphadenec­tomy was performed in 184 cases, and not performed in 73 cases. Results: There was no difference between two groups about tumor sizes. Also lymphovascular space invasion and histo­logic grade of two groups were similar. Omission of LA did not worsen DFS and OS in early stage low risk corpus cancer. Conclusions: Patients who have low risk corpus cancer, can be treated optimally with hysterectomy only

Reply to Comments on Effect of heating rate on kinetic parameters of beta-irradiated Li2B4O7:Cu,Ag,P in TSL measurements

We appreciate the opportunity to respond to comments regarding the paper published by Ege et al (2007 Effect of heating rate on kinetic parameters of beta-irradiated Li2B4O7: Cu, Ag, P in TSL measurements Meas. Sci. Technol. 18 889). We would like to thank the authors for taking the time to tell us about their opinion, but unfortunately we do not agree with them completely. In the article presented by Kumar and Chourasiya some comment is advanced to the analysis of the glow curves measured with different heating rates, presented in our recent study. According to our study, the area under the glow curve decreases with increasing heating rate in TL-temperature plots due to the quenching effects. Contrary to this, Kumar and Chourasiya suggest that this decrease is due to the normalization process. Here we hope to clarify any confusion regarding our published study

Effect of heating rate on kinetic parameters of beta-irradiated Li2B4O7 : Cu,Ag,P in TSL measurments

The effect of heating rate on the thermally stimulated luminescence (TSL) emission due to the temperature lag (TLA) between the TSL material and the heating element has been investigated using Li2B4O7:Cu,Ag,P dosimetric materials. The TLA becomes significant when the material is heated at high heating rates. TSL glow curves of Li2B4O7:Cu,Ag,P material showed two main peaks after beta-irradiation. The kinetic parameters, namely activation energy (E) and frequency factor (s) associated with the high temperature main peak of Li2B4O7:Cu,Ag,P were determined using the method of various heating rates (VHR), in which heating rates from 1 to 40 K s(-1) were used. It is assumed that non-ideal heat transfer between the heater and the material may cause significant inconsistency of kinetic parameter values obtained with different methods. The effect of TLA on kinetic parameters of the dosimeter was examined

Could serum levels of irisin be used in gestational diabetes predicting?

Objective: Gestational diabetes mellitus (GDM) is a metabolic disorder during pregnancy leading to acute and chronic complications in both mother and newborn. The pathogenesis of GDM has not been fully understood, However, since the disease shares risk factors with type 2 diabetes mellitus (T2DM), a relationship between these two disease states is plausible. The recently discovered peptide irisin has been hypothesized to be a regulator of body metabolism. However, studies ended up with controversial results. In the present study, we aimed to investigate the relationship between irisin levels and gestational diabetes mellitus and the possible benefits of the metabolic profile. Materials and methods: We performed a cross-sectional analysis of circulating levels of irisin in 100 pregnant women similar for age and body mass index and the groups included 50 gestational diabetic patients and 50 healthy pregnant volunteers. Serum irisin levels were measured by ELISA kit. Results: Mean age and body mass index levels were similar in both groups. Median HbA1c, fasting blood glucose, Glucose 1 h, Glucose 2 h and fasting insülin levels were higher in with gestational diabetic patients compared to the control group. In gestational diabetic group, the median irisin level was lower than in the control group. Conclusion: Serum irisin levels were lower in gestational diabetic patients. Further investigations are needed to explore the underlying biological effects of irisin on pregnant women. Keywords: Irisin, Gestational diabetes, Glucose intolerance, Hyperinsulinemia, Maternal insulin resistanc

Increased serum myonectin and irisin levels with myonectin and FNDC5 expressions in polycystic ovary syndrome: a case control study

The aim of this study is to assess the FNDC5 and myonectin expressions and serum levels of myonectin and irisin in women with PCOS. 90 participants were included in this case-control study. 45 of these participants were with PCOS, and 45 of them were healthy volunteers matched for age and body mass index (BMI). Serum irisin and myonectin levels were measured with commercially available enzyme-linked immune sorbent assay (ELISA) kits. Expression of the myonectin and FNDC5 genes were determined by RT-PCR analysis. It was found out that FSI, HOMA-IR, LH, LH/FSH, TT, serum irisin and serum myonectin levels, myonectin mRNA expression, and FNDC5 mRNA expression were higher in the PCOS group, whereas HDL-C level was lower in the PCOS group (p < .05). When the groups were compared, it was detected that IR and HA were significantly higher in the PCOS group (p < .05). Serum irisin and myonectin levels, and myonectin and FNDC5 mRNA expressions were increased in women with PCOS. These molecules can be target molecules in PCOS pathophysiology and treatment.IMPACT STATEMENT What is already known on this subject? Although the aetiology of PCOS is not fully understood, it is thought that insulin resistance may play a critical role. In recent studies, the relationship of cytokines secreted from skeletal muscle with insulin resistance has been shown. The effects of irisin and myonectin, which are members of the myokine family, on lipid and glucose metabolism are known. What do the results of this study add? Although there are many studies in the literature regarding serum irisin levels in women with PCOS, their results are confusing. There is a study in the literature investigating the relationship between myonectin and PCOS. In our study, we evaluated myonectin and FNDC mRNA expressions in addition to serum irisin and myonectin levels. As a result, we found that markers and their mRNA expressions were lower in patients with PCOS compared to controls. What are the implications of these findings for clinical practice and/or further research? We think that the results of our study will shed light on future studies. Due to their effects on adipose tissue, these markers may play a role in the aetiology of long-term complications of PCOS. Moreover, they can become pharmacological targets in preventing these complications

Luminescence from copper nanoparticles

The presence of copper nanoparticles in alumina and silica modifies their luminescence, and the changes in spectra are influenced by variations in the nanoparticle size distributions. Luminescence signals are sensitive to the total defect population. Thus the luminescence not only reflects changes caused by thermal annealing, which can modify both intrinsic defects and the copper nanoparticles, but also responds to the method of preparation of thin film layers. Copper nanoparticle influence on luminescence is reported both for ion-implanted bulk silica and for copper in pulsed laser deposition within alumina. Luminescence thus potentially offers a non-destructive monitor of the layer quality, reproducibility and growth conditions, as well as the state and size of the copper nanoparticles.We wish to thank the EPSRC, and BRITE EURAM for Contract No. BRPR-CT98-0616, Project No. BE 4427 (AMENIDAD), for financial support.Peer Reviewe
