Makale, WOS:000941436500004, Objective: This study was aimed to compare serum galectin-3 (Gal-3) levels in gestational diabetes mellitus (GDM) and healthy pregnant women and to evaluate the relationship between insulin resistance parameters and serum Gal-3 levels. Materials and Methods: Fifty-nine pregnant women who were screened for GDM with oral glucose tolerance tests (OGTT) at the 24th-28th gestational weeks were included in the study. According to the results of OGTT, 34 pregnant women were included in the GDM group and 25 pregnant women were included in the control group. Results: Serum Gal-3 value was found to be similar in the GDM and control group (P < 0.471). However, there was a significant positive association between Gal-3 and fasting insulin (r = 0.509, P < 0.001) and homeostasis model assessment of insulin resistance (HOMA-IR) (r = 0.479, P < 0.001) in the whole pregnancies, and between Gal-3 levels and fasting insulin (r = 0.608, P < 0.001), HOMA-IR (r = 0.609, P < 0.001), and OGTT 60 min glucose (r = 0.444, P = 0.016) in the GDM patients. Conclusions: There was no difference in the last trimester serum Gal-3 levels between GDM and healthy pregnant women. However, a significant positive correlation was determined between Gal-3 and fasting insulin, HOMA-IR, and OGTT 60 min glucose values in the GDM group, and fasting insulin and HOMA-IR values in whole pregnancies. The results of our study support previous data reporting the relationship between Gal-3 and GDM through insulin resistance., Scientific Research Projects (BAP) Coordination Unit of Selcuk University

Early Acsess In this study, it was aimed to assess effects of subclinical hyperthyroidism (SH) on bone metabolism using osteoprotegerin (OPG), sclerostin, Dickkopf-1 (DKK1) and biochemical parameters. This cross-sectional prospective study included 40 patients with SH and 40 euthyroid controls. Serum OPG, sclerostin, DKK-1, type-1 procollagen, C-terminal polypeptide (CTx) and 24-hours urine N-terminal telopeptide (NTx) were measures using ELISA kit. Bone mineral density measurements were performed using dual energy X-ray absorptiometry (DEXA). Risk for 10-years hip and major fracture was estimated by Turkish version of FRAX. No significant difference was detected in age, gender, body mass index, smoking and menopause rates between SH and control groups. The risk for 10-years hip fracture and major osteoporotic fracture were estimated as 4.45% and 0.55% in SH group, respectively. The OPG levels were significantly lower in patients with SH than controls (P = 0.017). No significant difference was detected in other bone formation and degradation parameters. No significant correlation was detected between OPG level and risk for major osteoporotic fracture (P > 0.05); however, a negative correlation was detected between OPG level and risk for hip fracture (rho = 0.233; P = 0.038). Serum OPG is markedly affected in patients with SH. In addition, OPG seemed to be associated with osteoporotic fracture risk. Available data show that SH is significantly associated with risk for fracture; thus, it is important to assess risk for fracture in patients with SH.

Amaç: Artmış asimetrik dimetil arjinin (ADMA) düzeyleri başta kardiyovasküler sistem olmak üzere birçok sistemde nitrik oksit (NO) düzeylerini azaltarak olumsuz etkilere neden olur. Helicobacter pylori (H. pylori) enfeksiyonun ADMA düzeylerinde artışa neden olduğu bilinmektedir. Bu çalışmanın amacı H. pylori ile enfekte bireylerde eradikasyon tedavisinin ADMA ve diğer metilarjinin metabolizma ürünlerinin serum düzeylerine etkisini değerlendirmek olarak belirlendi.Yöntemler: 14C üre nefes testi ve gaita antijen testlerinin her ikisinde pozitiflik tespit edilen hastalar H. pylori ile enfekte kabul edildi. Hastalara 14 günlük eradikasyon tedavisi (günde 2 kez 40 mg pantoprazol, günde iki kez 1000 mg amoksisilin ve günde iki kez 500 mg klaritromisin) verildi. Eradikasyon tedavisi öncesinde ve eradikasyon sağlanan hastalarda tedaviden 3 ay sonra ADMA, simetrik dimetil arjinin (SDMA) ve N-monometil-L-arjinin (L-NMMA) serum düzeylerinin ölçümü için kan örnekleri alındı. Bulgular: Çalışmaya dahil edilen 45 hastadan 23'ü kadın ve 22'si erkek idi. Hastaların ortalama yaşı 32,4±8 idi. Hastaların serum ADMA, SDMA ve L-NMMA düzeylerinde eradikasyon tedavisi sonrasında, tedavi öncesine göre anlamlı düzeylerde azalma olduğu görüldü.Sonuç: Bu çalışmada H. pylori eradikasyonu ile plazma ADMA, SDMA ve L-NMMA düzeylerinde anlamlı azalma olduğu gösterildi. H. pylori eradikasyonuna bağlı azalan serum ADMA, SDMA ve L-NMMA düzeylerinin, başta kardiyovasküler sistem olmak üzere bütün sistemlerde oluşturabileceği yararlı etkilerin değerlendirilmesi için geniş çaplı, uzun süreli çalışmalara ihtiyaç vardır, Objective: Increased asymmetric dimethylarginine (ADMA) levels are associated with reduced nitric oxide (NO) levels in many systems, particularly the cardiovascular system, and cause adverse effects. The objective of this study is to evaluate the effect of eradication therapy in patients infected with Helicobacter pylori (H. pylori) on the serum level of ADMA and other metabolic products of methylarginine.Methods: Patients who were found positive both in urea breath tests and stool antigen tests were considered to have H. pylori infection. These patients received eradication therapy for 14 days (twice daily pantoprazole 40 mg, twice daily amoxicillin 1000 mg, and twice daily clarithromycin 500 mg). Blood samples were taken to measure serum ADMA, symmetric dimethylarginine (SDMA), and N-monomethyl-Larginine (L-NMMA) levels before eradication therapy and 3 months after the therapy for patients for whom eradication was achieved. Results: A total of 23 of the 45 patients included in the study were female, whereas 22 were male. The mean age of the patients was 32.4±8 years. Significant reductions in the serum ADMA, SDMA, and L-NMMA levels of the patients were observed post-eradication therapy versus pre-eradication therapy. Conclusion: This study demonstrated significant reductions in serum ADMA, SDMA, and L-NMMA levels with H. pylori eradication. Further extensive long-term studies are needed to evaluate the positive effects that reduced serum ADMA, SDMA, and L-NMMA levels after H. pylori eradication can have on all systems, particularly the cardiovascular system

Benzene is the basic member of organic compounds classified as aromatic hydrocarbons. In many studies, it is determined that the risk of acute myeloid leukaemia (AML) or other leukaemias increase in conditions of recurrent exposure of benzene and products containing benzene. Benzene exposure can be determined by the analysis of phenol in urine. The aim of this study is to assess retrospectively the biochemical and hematological markers of workers who exposed to benzene.189 patients were included in this study who referred to Ankara Occupational Diseases Hospital for periodical examination that had exposed to benzene. 151 persons were included as control group. Phenol analysis was made by Agilent Gas Chromatography device, biochemical parameters by Konelab Prime 60i device, whole blood analysis by Beckman Coulter LH780 device and sedimentation measurement by Alifax device.While there were not a significant difference between benzene exposed workers and control group in aspartate aminotranspherase (AST), alanine aminotranspherase (ALT), creatinine, C-reactive protein, sedimentation and lymphocyte levels (p values; 0.935, 0.576, 0.673, 0.110, 0.171, 0.157 respectively), there were a significant difference in erithrocyte, leukocyte, hemoglobine, neutrophil and blood urea nitrogen levels (p values; 0.021, 0.045, 0.001, 0.018, 0.017 respectively). The mean erythrocyte and hemoglobine values were lower in benzene exposed workers according to control group, but the mean leukocyte, neutrophil and blood urea nitrogen values were higher in benzene exposed workers according to control group.As a result, although hematological effects of benzene and the relation between benzene and AML or other leukaemias were retained, we think that it should be investigated in more detail the effects on other systems in case of chronic exposure.
