    Notes: Abstract Fourteen strains of the yeastSaccharomyces cerevisiae were isolated from three wineries in the Salnés wine region (N.W. Spain) at the three different periods of the natural fermentation. Each wild yeast was screened for production of acetaldehyde, ethyl acetate, isobutanol,n-propanol, amylic alcohol and other important enological compounds during laboratory scale fermentations of grape juice. After 25 days at 20°C, the analytical results evidenced variations in the production of acetaldehyde (from 13.1 to 24.3 mg/l), isobutanol (from 27.7 to 51.1 mg/l), amyl alcohols (from 111 to 183 mg/l) and ethyl acetate (from 19.3 to 43.7 mg/l). Although isolated from the same wine region, differences in the wine composition were observed depending on the particular yeast strain used for the vinification experiments.

    Notes: Abstract Fermentative behaviour and cell growth have been studied in grape juice inoculated either with two killerSaccharomyces cerevisiae wild strains or with their Acridine Orange-cured isogenic counterparts. The number of viable cells/ml at the beginning of the fermentation, as well as during exponential growth, were higher in grape juices inoculated with the cured strains. The CO2 production, fermentative rate and ethanol and acetic acid production were also higher in the cured strains, particularly during the stage of active fermentation. These differences, however, were minimal at the end of the fermentations.

    Notes: Abstract We report a 5-year experience performing vesicovaginal fascial sling operation (VVFSO) for the treatment of genuine stress incontinence associated with prolapse. This original technique, plus others to correct prolapse, was employed in 41 women evaluated preand postoperatively with traditional clinical and urodynamic methods. Essentially the procedure is a transvaginal retropubic urethrocystopexy by means of two fascial strips, obtained from the central part of the cystocele, crossed beneath the urethrovesical junction and fixed to the periostium of the lower retropubis on each side. All 41 patients were followed for 1–5 years, with 39 of them cured (95.1%) and 2 failed (4.9%). A significant postoperative increase in the maximal urethral closure pressure, from 10–35 cmH2O with a mean of 18, was found. The VVFSO is an easy vaginal procedure, which provides a high success rate in correcting GSI associated with prolapse.
