    Molecular analysis of the lac operon encoding the binding-protein-dependent lactose transport system and β-galactosidase in Agrobacterium radiobacter (1992)
    Oxford, UK : Blackwell Publishing Ltd

    Notizen: The genes coding for the binding-protein-dependent lactose transport system and β-galactosidase in Agrobacterium radiobacter strain AR50 were cloned and partially sequenced. A novel lac operon was identified which contains genes coding for a lactose-binding protein (lacE), two integral membrane proteins (lacF and lacG), an ATP-binding protein (lacK) and β-galactosidase (lacZ). The operon is transcribed in the order lacEFGZK, The operon is controlled by an upstream regulatory region containing putative -35 and -10 promoter sites, an operator site, a CRP-binding site probably mediating catabolite repression by glucose and galactose, and a regulatory gene (lacl) encoding a repressor protein which mediates induction by lactose and other galactosides in wild-type A. radiobacter (but not in strain AR50, thus allowing constitutive expression of the lac operon). The derived amino acid sequences of the gene products indicate marked similarities with other binding-protein-dependent transport systems in bacteria.

    Muscarinic involvement in vascular and adrenal medullary responses to splanchnic nerve stimulation in conscious calves (1994)
    Springer

    Notizen: Abstract Stimulation of the peripheral end of the right splanchnic nerve (4 Hz for 10 min) in the presence of hexamethonium caused a small but significant rise in mean aortic blood pressure which was subsequently abolished by atropine. There were also small but significant increases in the outputs of catecholamines, [Met5]-enkephalins and corticotrophin releasing factor (CRF) from the right adrenal gland. The catecholamine response was roughly halved after atropine while the outputs of enkephalins and CRF were unaffected. It is concluded that splanchnic sympathetic postganglionic neurones supplying the vasculature are completely blocked by cholinergic blockade whereas adrenal medullary responses persist in an attenuated form.

    Thema: Medizin
    Notizen: Summary Progressive disseminated histoplasmosis (PDH) has been described in only six patients with hairy cell leukemia (HCL). Herein we describe an additional patient with HCL and disseminated histoplasmosis. Additionally, we note that three of seven cases of disseminated histoplasmosis and HCL have occurred in East Texas. PDH is to be suspected in febrile HCL patients in an endemic area who fail to respond to antibacterial therapy. We emphasize that serologic studies are useful in the diagnosis of PDH in HCL patients, and these patients respond well to therapy.

    Concentration fluctuation data from dispersion experiments carried out in stable and unstable conditions (1994)
    Springer
    Boundary layer meteorology 67 (1994), S. 41-74 
    Details
    ISSN: 1573-1472
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Geologie und Paläontologie , Physik
    Notizen: Abstract Experiments have been carried out to investigate the dispersion of plumes at short range in the atmospheric boundary layer during stable and unstable conditions. The experiments and measurement system are described, and the results are compared with those of previous experiments. The slow meandering under stable conditions found by Mylne (1992) is not present here (probably because of topographic effects), so the plume is present on the mean centreline more often, and timescales are shorter, under stable conditions. Associated with this, statistics during stable conditions exhibit greater stability to changes in total sampling time. Intensity is found to be greater under unstable conditions, but there do not appear to be large differences in the shape of the probability density function between stable and unstable conditions. The intermittency is calculated using several variations on the conventional definition. The values obtained vary substantially according to which definition is used (although they are always higher in the stable than in the unstable experiments), demonstrating the sensitivity to both the precise definition and to measurement system characteristics. It is shown that even at very short range the mean and variance of concentration are determined almost entirely by the fluid not emanating from the source. Thus the partition between source and non-source fluid suggested by Chatwin and Sullivan (1989), while providing a more scientifically sound definition of intermittency, does not have an obvious direct practical application.

    A standardized format for handling data on plasmids, viruses and transposons: The PVT database format (1992)
    Springer
    World journal of microbiology and biotechnology 8 (1992), S. 519-526 
    Details
    ISSN: 1573-0972
    Schlagwort(e): Database format ; plasmids ; transporsons ; viruses

    Thema: Biologie , Werkstoffwissenschaften, Fertigungsverfahren, Fertigung
    Notizen: Abstract The PVT format described here has been designed to store and retrieve genetic data on plasmids, viruses or transposons with special focus on their applications. Both naturally-occurring and engineered elements can be included in it. A variety of data can be accommodated in fields that are grouped in blocks: name and type of element, database administration, element administration, history, propagation, selection and host, biological properties, cloned insert and applications. The number of fields, now 157, can be expanded as required. Most properties can be described in simple logical fields. The format is organized to permit rapid searches and to facilitate communication between database and user; connection with culture and/or DNA collections is also envisaged and adequate fields for these tasks have been provided. The format allows cross-reference with that originated by the Microbial Information Network Europe (MINE) for computer storage and handling of bacterial or fungal strain data.

    The tumor promoter pristane activates transcription by a cAMP dependent mechanism (1992)
    Springer
    Molecular and cellular biochemistry 110 (1992), S. 75-81 
    Details
    ISSN: 1573-4919
    Schlagwort(e): pristane ; tumor promoter ; cAMP response element
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Biologie , Chemie und Pharmazie , Medizin
    Notizen: Abstract Pristane is a naturally occurring isoprenoid which is believed to be derived from the phytyl moiety of chlorophyll. Thus it is not surprising that pristane is present in many common fruits or vegetables and furthermore can be detected in tissues of fish and mammals. Using the rat as an animal model, pristane can function as a potent tumor promoter. It is conceivable that pristane could play a role in the development of certain malignancies in higher mammals since it is commonly found in the diet. At the molecular level, pristane can induce changes in the plasma membrane, alter the conformation of chromatin, as well as selectively activate gene expression. This study was undertaken to identify specific transcriptional motifs which are responsive to pristane. A transcriptional promoter which contained a cAMP response element (CRE) was consistently stimulated by pristane in several mouse and primate cell lines. A promoter construct which contained a single copy of the TPA response element (TRE) was also activated by pristane but surprisingly a promoter which contained multiple copies of the TRE was not. Activation of the TRE required 10 fold higher concentrations of pristane relative to activation of the CRE. Within two hours after addition of pristane to monkey fibroblasts (CV-1) levels of cAMP were increased more than two fold relative to controls. These data indicated that pristane can increase the level of cAMP in CV-1 cells and consequently stimulate transcriptional promoters which contain a CRE.

    Modified urethral sling for the treatment of genuine stress incontinence and latent incontinence (1994)
    Springer
    International urogynecology journal 5 (1994), S. 69-75 
    Details
    ISSN: 1433-3023

    Thema: Medizin
    Notizen: Abstract The results of 143 women who underwent a modified urethral sling using Marlex mesh for the correction of stress urinary incontinence and latent stress incontinence, as diagnosed by clinical and urodynamic testing, are examined. The overall success rate for the surgical correction of genuine stress urinary incontinence was 99% during a median follow-up time of 1 year (range 0.12–4 years). There was a 12% postoperative incidence of varying degrees of genital prolapse. Difficulty with voiding resulting in the need for self-catheterization occurred in 17% of patients in the first 6 weeks, but only 2.8% were needing self-catheterizing after 1 year. There was a difference in peak flow preoperatively compared with 1 year postoperatively (20.5 ml/s v 15.7 ml/s, P=0.0003). Patients with a normal peak flow preoperatively (〉20 ml/s) were more compromised at 1 year postoperatively (28 ml/s preoperatively, 18.4 ml/s postoperatively, P=0.00001), than women with an abnormal preoperative flow (〈20 ml/s), (13.2 ml/s preoperatively, 13.5 ml/s postoperatively). Whether the operation was done for overt or latent stress incontinence did not affect postoperative flow results. It was not possible to predict by preoperative uroflow testing which patients were likely to need intermittent self-catheterization postoperatively. One year after surgery there were no significant alterations in bladder capacity (CMG) or urethral pressure profile measurements. There were no statistically significant changes in uroflow patterns when comparing primary and secondary surgical groups.
