Item type:Publication, Association between foetal growth and different maternal metabolic characteristics in women with gestational diabetes mellitus(Macedonian Academy of Sciences and Arts/De Gruyter, 2009-12); ; Dimitrovski, ChedomirObjective: The aim of the study was to investigate the association between foetal growth and different maternal metabolic characteristics in women with gestational diabetes mellitus (GDM). Methods: The study group included 200 consecutive pregnant women who attended the Endocrinology, Diabetes and Metabolic Disorders Outpatient Department in the period from 02.2006 to 02.2009 with singleton pregnancy and GDM diagnosed following ADA criteria. The following parameters were studied: pre-pregnancy maternal body mass index (BMI), 3-hours 100g oral glucose tolerance test (OGTT) results, glycosylated haemoglobin (HbA1c), total lipids (TL), total cholesterol (TH), triglycerides (TG), HDL- and LDL-cholesterol levels at admission. Neonatal birth weight and the prevalence of being large for gestational age (LGA) was an end-point. Results: We found a significant association between birth weight and pre-pregnancy BMI, HDL-C and birth weight of a large child born previously. Birth weight of a large child born previously was the strongest independent predictor for LGA. The prevalence of LGA (from 27% to 80%) was related to a number of altered maternal characteristics. Conclusion: Pre-pregnancy BMI, HDL-C and birth weight of a large child born previously are the independent predictors for LGA, but results of glucose levels during OGTT are not useful in the prediction of LGA in GDM pregnancies. Probably more factors and other maternal metabolic parameters than glucose levels during OGTT are responsible for the risk of LGA. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Gestational Diabetes Mellitus - the impact of maternal body mass index and glycaemic control on baby's birth weight(Macedonian Academy of Sciences and Arts/De Gruyter, 2009-12); ; ; Objectives. To asses the influence of the maternal BMI and glycaemic control in women with GDM on the baby's birth weight (BW). Material and methods: We analysed 180 women with GDM. Macrosomia has been defined as BW > 4000 gm, small for gestational age < 2700 gm and appropriate for gestational age between both. According to the baby´s BW the pregnant women were divided into three groups: group 1 (G1) with BW < 2700 gm (n = 26); group 2 (G2) with BW between 2700 to 4000 gm (n = 117), and group 3 (G3) with BW > 4000 gm (n = 37). We also analysed BMI (kg/m²), HbA1c (%), PPG (mmol/L) and time of delivery (WG). Results: Comparisons between G1 and G2 showed: BMI (30.7 ± 5 & 31 ± 5.2; p < 0.7), HbA1c (6.4 ± 0.8 & 5.1 ± 0.8, p < 0.002), PPG (8.2 ± 1.7 & 6.9 ± 1.5, p < 0.02), time of delivery (35.2 ± 3.8 & 38.6 ± 1.5, p < 0.0001) and BW (2289 ± 504 & 3474 ± 334, p < 0.0001). Comparisons between G2 and G3 showed: BMI (31 ± 5. 2 & 33.4 ± 6.1; p < 0.02), HbA1c (5.2 ± 1.1 & 6.4 ± 2.3, p < 0.02), PPG (6.9 ± 1.5 & 8.2 ± 1.9, p < 0.02), time of delivery (38.6 ± 1.5 & 39.3 ± 1.4, p < 0.01) and BW (3474 ± 334 & 4431 ± 302, p < 0.0001). Comparisons between G1 and G3 showed the difference at delivery time and the baby's BW (p < 0.0001). Conclusions: Maternal obesity and PPG contribute to macrosomia and also PPG to SGE. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Erythropoietin reduces cumulative nephrotoxicity from cisplatin and enhances renal tubular cell proliferation(Macedonian Academy of Sciences and Arts, 2008-12); ; ; ; Cisplatin, a heavy metal complex, is one of the most active drugs used in the treatment of several human malignancies. However, high-dose therapy with cisplatin is limited by its cumulative nephrotoxicity. The main objectives of this study were to determine the role of recombinant human erythropoietin (Epoetin alfa) in the prevention of nephrotoxicity induced experimentally in Wistar rats by long-term administration of cisplatin (2 mg/kg/b.w./week) over eight weeks, and an evaluation of its effect on renal tubular cell proliferation. The animals were randomly assigned into three groups, each including 25 rats. Group 1 (CP) received only cisplatin (2 mg/kg/b.w./week), group 2 (CP+EPO) received cisplatin (2 mg/kg/b.w./week) and epoetin alfa (150 IE/kg/b.w./three times a week), and group 3 (control group) received only saline. During the study, the following tests for the assessment of the renal function and renal damages were performed: determination of concentration of serum creatinine and BUN and determination of total protein quantity in 24-hour urine samples. At the end of the study, the abdomen was opened and both kidneys of the rats were removed and sent for histological and morphometric analysis. Ki-67 was used as a tool to determine a proliferative index. The results obtained have shown that epoetin alfa significantly reduced the functional renal failures and renal damages, and increased toleration of high doses of cisplatin. At the same time, our results with regard to tubular proliferative index have confirmed that one of the possible mechanisms by which erythropoietin accomplishes its renoprotective effect is stimulation of tubular cell proliferation and regeneration. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Effects of Rosiglitazone on Metabolic Parameters and Adiponectin Levels in Fructose-Fed Rats(Scientific Foundation Spiroski (publications), 2009-03-01); ; ; ; Dimitrovski, ChedoAim. To investigate the effect of the peroxisome proliferators-activator receptor gamma agonist, rosiglitazone, on metabolic parameters and adiponectin levels in an animal model of the metabolic syndrome. Material and methods. Metabolic syndrome was induced in 32 male Wistar rats by adding a fructose in drinking water for 12 weeks. During the last 4 weeks, 16 rats were treated with rosiglitazone (5 mg/kg/day), while the remaining 16 did not receive any medication (fructose group). Another control group consumed standard rat chow and water for 12 weeks. Results. Chronic fructose administration induced a significant increase in systolic blood pressure (SBP), body weight, serum triglycerides (TG), free fatty acids (FFA), insulin, glucose AUC0-120 (during oral glucose tolerance test) and decreased serum high density lipoprotein (HDL) cholesterol and adiponectin concentrations compared with the control group. Treatment with rosiglitazone over the final 4 weeks reversed these effects and significantly reduced SBP, TG, FFA, insulin concentrations and glucose AUC0-120 compared with the fructose group. In addition, rosiglitazone increased serum levels of adiponectin twofold from 3.44 ± 0.46 to 7.03 ± 1.30 μg/ ml. Conclusion. This study indicates that rosiglitazone treatment improves the components of the metabolic syndrome, which is accompanied with an increase in adiponectin concentrations. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Effect of angiotensin II type 1 (AT1) receptor antagonist on the endothelial dysfunction in spontaneously hypertensive rats in correlation with the nitric oxide system(Comenius University, School of Medicine - AEPRESS SRO, 2003); ; ; Jovanoska, EHypertension is associated with impaired endothelial function, which can be explained by a decrease in nitric oxide (NO) generation or by an enhanced inactivation of NO after its release from endothelial cells. The aim of this study was to investigate the effect of long-term treatment with losartan, an angiotensin II (AT1) receptor antagonist, on endothelial dysfunction in an animal model of hypertension in relation to the nitric oxide system. Losartan was administered to 48 sixteen-week-old spontaneously hypertensive rats, in a dose of 10 mg/kg bw/daily in drinking water, for 12 weeks. Systolic blood pressure (SBP) was measured at the beginning, after 4, 8 and 12 weeks of treatment, by the tail-cuff plethysmographic method. At each mentioned time point, a group of 12 animals was sacrificed and blood was withdrawn from the abdominal aorta. Plasma samples were used for determination of total nitrate/nitirite levels, cyclic guanosine monophosphate (cGMP) and endothelin (ET) 1 levels. Statistical evaluation of the results was performed by the use of a computer statistical programme Statistica for Windows 5.0. Losartan produced a significant decrease of SBP at all time points. On the other hand, long-term treatment with this AT1 receptor antagonist produced a significant increase of nitrate/nitrite and cGMP plasma levels. When we compared the values of SBP with plasma nitrate/nitrite as well as with cGMP values, a statistically significant correlation was established. A statistically significant decrease in plasma endothelin 1 values was found during the whole study period. Also, a positive correlation between SBP and plasma endothelin 1 concentrations was observed. Long-term losartan (AT1 receptor antagonist) treatment, apart from its blood pressure lowering effect in hypertension, has beneficial effects on the endothelial dysfunction which is at least partially due to the activation of the nitric oxide system.

Item type:Publication, The changes of ACTH, cortisol, testosterone and testosterone/cortisol ratio in professional soccer players during a competition half-season(Comenius University, School of Medicine - AEPRESS SRO, 2006-02); ; ; Mickoska, EThe following up of some hormonal parameters during the professional soccer training process could be one of the indicators of the training effects. On the other hand, overreaching and overtraining as an opposite adaptation of supercompensation could be detected by following up some hormonal changes. The aim of this study is to evaluate the changes in some hormonal parameters in professional soccer players during a half-season competition. We included 30 professional soccer players from a soccer club of our National Soccer League in this study. All sport medical examinations were conducted tree times: before the preparation phase, before the competition phase (after previous phase) and after finishing the competition phase. There were significant differences in all evaluated hormones between three phases of soccer training process, including significant decrease in T/C of more than 30% at the end of the competition phase (phase III). The decrease in muscle mass after the preparation phase and the increase in fat mass at the end of competition phase were insignificant. The hormonal changes indicated that some indices could indicate overreaching and overtraining at the end of professional soccer competition season. Although insignificant, the decrease in muscle mass after the preparation phase and the increase in fat mass at the end of competition phase were undesirable effects for us (Tab. 4, Fig. 2, Ref. 19). - Some of the metrics are blocked by yourconsent settings
