Radiation therapy is a popular and useful tool in the treatment of cancer. Melatonin participates in the regulation of a number of important physiological and pathological processes. Melatonin, a powerful endogenous antioxidant, plays a role in the reduction of oxidative damage. Thirty adult rats were divided into five equal groups. On the day of the experiment, groups I and II were injected with 5 or 10 mg/kg melatonin, respectively, while group III received isotonic NaCl solution. Thirty minutes ...

The infrastructure investments are analyzed by taking the EU 12 and EU 15 division into account as a contribution to previous studies. The study comprised the period between 1980-2010 for EU 15, EU 12 and EU 27 and used generalized momentum method (GMM). Results of the study show that telecommunications investments have positive effects on growth in all groups, energy investments have positive effects in EU 15-EU 27 groups and investments on railway and road have positive effects only in EU 27group.

Although there are many investigations on protein glycation in diabetic patients, many detailed studies are needed on this subject. In this study, the correlation between red cell membrane and serum protein glycation was investigated in NIDDM. The relation of membrane glycation to intracellular Na+ and K+ levels was also considered. Forty patients with NIDDM and 22 healthy subjects were included in the study. The membrane proteins were isolated, and total protein (TPm) and fructosamine (FAm) levels ...

Hematologic parameters such as mean platelet volume (MPV), red cell distribution width (RDW), and neutrophil to lymphocyte (N/L) ratio are associated with increased cardiovascular risk. We investigated the effect of atorvastatin on hematologic parameters in patients with hypercholesterolemia. A total of 79 patients with hypercholesterolemia and 47 normocholesterolemic healthy participants were included. Patients with hypercholesterolemia received 10 to 80 mg/d atorvastatin during a 24-week period. ...

A total of 34 pregnant women with FGR and 62 patients with uncomplicated pregnancy were included. Neopterin and CRP levels were measured at the time of diagnosis. The primary outcome of this study was to compare the neopterin and CRP levels in pregnant women with FGR and those with ...

In this paper, we consider a new approach for estimating the fundamental period in fetal ECG waveforms. The fundamental period contains information that is indicative of the physiological condition of the fetus such as hypoxia and acidemia. Our method is based on the minimization of a cost function that measures the differences between the discrete Fourier transform (DFT) of the fetal ECG waveform and the DFTs of its circularly shifted forms. By using the linear phase shift property of the DFT, we ...

A novel voltammetric method for boron determination in ppb level is described. Boron complexes with Alizarin Red S (ARS) and the complex, as well as the free ligand, both adsorbs on a hanging mercury drop electrode. The method is based on the monitoring the anodic peak of the complex at -0.47 V in ammonium acetate-phosphate buffer (pH 7). The maximum peak current was obtained by scanning the potential from -700 mV versus Ag/AgCl to more positive potentials without accumulation in the presence of 1 x ...
