If dwarf galaxies are primeval objects in the Universe, as hierarchical galaxy formation scenarios predict, they should show traces of their old stellar populations, perhaps distributed in extended, differentiated structures. The working hypothesis that such a structure could exist is tested for the case of DDO 187, a field dIrr galaxy showing a high gas fraction and low metallicity. For this p...
AIM To determine the factors affecting medical students' choice of the specialty of family medicine. METHODS The study was conducted in the period from 2004-2006 and comprised 770 first-year medical students from Ondokuz Mayis, Karadeniz Technical, Kocaeli, and Adnan Menderes Universities, Turkey.

AIM To evaluate whether pathologically early hepatocellular carcinoma (HCC) exhibited local tumor progression after radiofrequency ablation (RFA) less often than typical HCC. METHODS Fifty pathologically early HCCs [tumor diameter (mm): mean, 15.8; range, 10-23; follow-up days after RFA: median, 1213; range, 216-2137] and 187 typical HCCs [tumor diameter (mm): mean, 15.6; range, 6-30; follow-...
A 21-kD protein isolated earlier from potato tubers (Solanum tuberosum L.) has two isoforms, with pI 6.3 and 5.2, which were separated by fast protein ion-exchange chromatography on a Mono Q column. The primary structures of the two forms consisted of 187 and 186 amino acid residues. Both isoforms are composed of two polypeptide chains, designated A and B, linked by a single disulfide bond betw...
BACKGROUND AND PURPOSE The aim of this study was to investigate regional cerebral blood flow parameters during the postacute phase of unilateral ischemic stroke and to correlate them with clinical data. METHODS Regional cerebral blood flow was measured in 187 patients in the stabilized phase of stroke by the xenon-133 inhalation method with 32 extracranial detectors. Thirty-eight patients wer...
