Aim: The prognostic value of circulating antibodies to oxidized low-density lipoprotein (anti-oxLDL) in patients with coronary heart disease is not completely clear. We aimed to investigate the association between levels of anti-oxLDL in three groups of patients with different grades of severity of coronary heart disease. Patients and methods: The study included 101 patients classified into three groups: one (N=35) with acute myocardial infarction (AMI), a group (N=35) with angiographicallly proven coronary artery disease (APCAD), and a group without angiographicallly proven coronary artery disease (N=31) designated as a control group. Levels of IgG anti-oxLDL antibodies were meausured by enzyme-linked immunosorbent assay. Results: Mean anti-oxLDL value was significantly higher in patients with AMI than in patients with APCAS (1342.1±581.5 mIU/ml vs. 553.0±183.3 mIU/ml, p<0.001), as well as compared with control group (1342.1±581.5 mIU/ml vs. 246.5±114.3, p<0.001). Similarly, significant difference in anti-oxLDL levels was found between the patients with APCAS and control group (p<0.001). Conclusions: The present study showed that elevated levels of anti-oxLDL are positively related with a severity of coronary artery disease. Hence, elevated levels of anti-oxLDL may identify patients with unstable coronary heart disease. Oxidized LDL in circulating plasma could serve as a marker of cardiovascular events.

SUMMARY: We present the central velocity dispersion measurements of the nearby galaxies from the Sloan Digital Sky Survey (SDSS). Using the sample from the paper by Ho et al. 2009, we have selected 23 galaxies for which we calculate the velocity dispersion. We have used the Penalized Pixel-Fitting code (Cappellari and Emsellem2004) to measure the velocity dispersion throughout the four chosen spectral regions: (3800,4568)” (4568,5336)” (5336,6104) and (6104,6872)” In all these regions, we have separately calculated dispersions and corresponding errors. We found that the measured values may vary with the change of spectral region, but, if weighted properly with the measure of the goodness of the flt, the flnal results will be shifted coloser to those for the best fltting regions. We have also tested how the use of difierent spectral libraries (Miles, Valdes and Elodie databases) in∞uences measurements and we showed that they do not afiect measurements much. However, Elodie stellar library introduces the smallest errors in the velocity dispersion and it is the most stable throughout all four spectral regions. For these reasons it should be used preferentially when dealing with the SDSS spectra. We compare the results with the above mentioned paper and flnd a reasonable agreement. The agreement with the dispersions available in the HyperLeda database is very poor. The best agreement is obtained with SDSS measurements. We believe that our measurements are useful since SDSS velocity dispersions measurements are not available for many galaxies and the method of calculation of the velocity dispersion outlined in this work enables calculation of velocity dispersion for any galaxy. Of course, spectra with signal-to-noise ratio below 20 should be taken with caution.

UDK 582.475:577(497.6 Očevija) Priznatim biokemijskim biljezima analizirana je genetička struktura obične jele sa područja Očevije, u centralnom području Bosne i Hercegovine. Za analizu smo uporabili biokemijske biljege, i to 9 enzimskh sustava sa 16 genskih lokusa, odnosno 7 polimorfnih gen lokusa sa 25 alela. Prosječan broj alela po lokusu je 1,6471. Genetički multilokusni diverzitet je iznosio 28,42, a gen pool diverzitet 1,1682 , dok je stvarna heterozigotnost iznosila 0,1992. Ovi rezultati i njihova usporedba sa rezultatima drugih istraživanja ukazuju da populacija Očevija ima specifičnu genetičku strukturu karakterističnu za pionirske vrste ali sa autohtonim genofondom svojstvenim za Bosnu i Hercegovinu.
