    Description / Table of Contents: Résumé Les préférences alimentaires des termites xylophages ont été mesurées en comparant les différentes biomasses de bois prélevées, les pourcentages de bois consommé et l'importance des dégâts en fonction de catégories arbitrairement définies. Quand les caractéristiques des bois examinés différent, par exemple la densité, ces comparaisons ne sont plus possibles. Nous avons examiné les réactions de Coptotermes formosanus Shiraki (Iso., Rhinitermitidae) en présence de bois différant par leurs caractéristiques physiques, par compression du bois jusqu'à une densité dépassant de 40% la densité naturelle. Les termites consomment alors significativement moins en pourcentage, mais les biomasses consommées sont voisines de celles que l'on observe avec du bois du pin normal. Par contre, elles consomment significativement plus de biomasse, mais les mêmes pourcentages d'acajou compressé ou normal. Savoir quel critère doit être préférentiellement utilisé: le pourcentage ou la fraction de biomasse prélevé, dépend de la nature des facteurs de régulation de la taille du repas chez les termites. Si les termites consomment des repas de biomasse déterminée, alors la biomasse consommée est un bon critère: s'ils consomment un repas de volume déterminé, alors le pourcentage prélevé est un critère satisfaisant.
    Notes: Abstract Feeding preferences of xylophagous termites have been determined by comparing differences in wood biomass removed, percentage of wood consumed or degree of damage rated in arbitrary categories. When test woods differ in physical characteristics such as density, these measures are not comparable. We examined the response of the Formosan termite, Coptotermes formosanus Shiraki (Isoptera: Rhinotermitidae) to wood that differed in physical characteristics by compressing blocks to 40% greater than the natural density. Termites ate significantly greater percentages, but similar amounts of biomass, of uncompressed over compressed natural pine. In contrast, they ate significantly greater amounts of biomass, but similar percentages, of compressed over uncompressed mahogany. Whether percentage or amount of biomass removed should be used as a measure of preference depends on what regulates insect meal size. If termites consume meals of fixed biomass, then biomass consumed is the correct measure; percentage removed is appropriate if they consume meals of fixed volume.

    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
    Keywords: Marlex mesh ; Suburethral sling ; Urinary incontinence

    Topics: Medicine
    Notes: 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.

    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
    Keywords: Database format ; plasmids ; transporsons ; viruses
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: 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.
