    Microscopic hematuria (1992)

    Notes: Abstract Asymptomatic microhematuria is not a rare phenomenon among apparently healthy individuals, and the incidence of such hematuria increases significantly with age. Some investigators report that the cause of hematuria is renal glomerular disease in more than 50% of patients, and urological malignancies in 1.0%–13%. On initial examination, urine sediments must be searched for evidence of renal glomerular disease, such as RBC casts and dysmorphic RBCs. If the patients were diagnosed to have glomerular disease, follow-up studies, without any extended examination or therapy are recommended, because their prognosis is usually favorable. The next step is to perform thorough urological examinations, including urine cytology, cystoscopy, abdominal ultrasound, and intravenous pyelography, to detect serious underlying disease. Even if no significant findings were observed after the extensive urological examinations, careful follow-up studies should be performed at 6–12-month intervals for 3 years, using the same methods.

    Sequence analysis of putative structural regions of hepatitis C virus isolated from 5 Japanese patients with hepatocellular carcinoma (1993)
    Springer
    Archives of virology 128 (1993), S. 163-169

    Notes: Summary The nucleotide sequences of the 5′-portion of the HCV genome, consisting of 2672 nucleotides, were determined by analysis of clones derived from 5 different patients with liver cirrhosis and hepatocellular carcinoma. Comparison of 5 genomes and 8 isolates already reported demonstrated the significant genome diversity in the structural regions. Genetic divergence was outstanding in the envelope regions (E1 and NS1/E2, 〉59.7% identity) in contrast to the sequence conservation of the 5′ non-coding (〉93.8% identity) or core regions (〉82.0% identity). Although hypervariable regions were found in the NS1/E2 region as reported, hydropathicity was maintained for all clones, reflecting the biological functions of these regions.

    Excess enthalpies and excess heat capacities of the binary mixtures of acetonitrile, dimethylformamide, and benzene at 298.15 K (1992)

    Description / Table of Contents: Zusammenfassung An binären Gemischen aus Acetonitril, Dimethylformamid und Benzol wurden bei 298.15 K die Überschußenthalpien und die isobaren Überschußwärmekapazitäten gemessen. Die Überschußenthalpie von Acetonitril + Benzol ist positiv, die von Acetonitril + Dimethylformamid ist negativ. Die Überschußenthalpie ist bei Dimethylformamid positiv und wie bereits berichtet [1] annähernd Null. Die Überschußwärmekapazität von Acetonitril + Benzol und Benzol + Dimethylformamid wechselt bei Zunahme von Benzol das Vorzeichen von negativ zu positiv. Die von Acetonitril + Dimethylformamid ist nicht einfach. An beiden Enden der Molenbruchskaie ist sie leicht positiv und nicht allzu negativ in der Mitte der Molenbruchskale. Die Kurve flacht in dieser Region ab.
    Notes: Abstract Excess enthalpies and excess isobaric heat capacities of binary mixtures consisting of acetonitrile, dimethylformamide and benzene were measured at 298.15 K. Excess enthalpy of acetonitrile + benzene is positive and that of acetonitrile + dimethylformamide is negative. That of dimethylformamide + benzene is positive and nearly equals to zero as shown in the previous report [1]. Excess heat capacities of acetonitrile + benzene and benzene + dimethylformamide change sign from negative to positive with increase of benzene. That of acetonitrile + dimethylformamide is not simple. It is slightly positive near both ends of mole fraction and not so large negative in the middle of mole fraction. The curve tends to flatten in that region.

    The nature of initiation sites on DNA for the core RNA polymerase (1971)
    Springer
    Molecular genetics and genomics 111 (1971), S. 66-76 
    Details
    ISSN: 1617-4623
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary The biological significance of the low level of symmetric and non-specific RNA synthesis catalyzed by the core RNA polymerase devoid of the sigma factor has been analyzed. Shearing of DNA's including T4 DNA markedly increased the template activities with the core enzyme but not with the holoenzyme. This finding suggests that RNA synthesis by the core enzyme increases concomittantly with the production of termini in DNA. Double-stranded circular DNA's such as λdv and fd-RFI were found to be inactive as templates for the core enzyme, but were made active by introduction of single-strand nicks with deoxyribonuclease. In contrast, single-stranded circular DNA (ϕX 174) served as a good template for RNA synthesis by the core RNA polymerase. These findings suggest that the sigma factor may activate double-stranded DNA at the promotor sites by creating proper initiation points for RNA synthesis. Partial separation of duplex DNA into single-stranded forms at the promotor sites could be one of the processes in the reaction catalyzed by the holoenzyme containing the sigma factor.
