Constraints on cosmic strings from the LIGO-Virgo gravitational-wave detectors. - Physical review letters
Cosmic strings can give rise to a large variety of interesting astrophysical phenomena. Among them, powerful bursts of gravitational waves (GWs) produced by cusps are a promising observational signature. In this Letter we present a search for GWs from cosmic string cusps in data collected by the LIGO and Virgo gravitational wave detectors between 2005 and 2010, with over 625 days of live time. We find no evidence of GW signals from cosmic strings. From this result, we derive new constraints on cosmic string parameters, which complement and improve existing limits from previous searches for a stochastic background of GWs from cosmic microwave background measurements and pulsar timing data. In particular, if the size of loops is given by the gravitational backreaction scale, we place upper limits on the string tension GÎ¼ below 10(-8) in some regions of the cosmic string parameter space.
Ureterovaginal fistula linked to a retained pessary. - International urogynecology journal
The vaginal pessary is a safe and effective method for the correction of uterovaginal prolapse. Complications are uncommon, but include fistula formation. We report a case of fistulous communication between the ureter and vagina that developed in a patient who had had a pessary for more than 8 years. She initially presented with urinary retention secondary to complete procidentia and declined surgical intervention. The patient was not compliant with follow-up. Eventually, she was scheduled for a vaginal hysterectomy and pelvic floor reconstruction, during which the communicating tract was discovered between the ureter and vagina. Ultimate treatment involved stenting of the ureter and interval ureteroneocystostomy. Fistulae can develop between the ureter and the vagina in the case of procidentia and a retained pessary.
Mapping of yeast Rpn4p transactivation domains. - FEBS letters
The 26S proteasome is a multi-subunit protease complex and plays an essential role in many basic cellular processes. The abundance of the 26S proteasome is controlled by a negative feedback circuit that involves the Rpn4p transcriptional activator. To date, the functional regions of Rpn4p are largely unknown. We mapped the Rpn4p transactivation domains by deletion analysis. The distal acidic domain has stronger transactivation potential than that of the proximal acidic domain. However, the N-terminal region, and not the acidic domains of Rpn4p, is crucial for Rpn4p function. Within the N-terminus, we mapped a novel transactivation domain, which may be regulated by some modification of lysines in a proteolysis-independent manner.
The use of reinforced composite resin cement as compensation for reduced post length. - The Journal of prosthetic dentistry
Cements that yield high retentive values are believed to allow use of shorter posts.This study investigated the use of reinforced composite resin cement as compensation for reduced dowel length.The retention values of stainless steel posts (parallel-sided ParaPost and tapered Dentatus in 5-, 8-, and 10-mm lengths) luted with Flexi-Flow titanium-reinforced composite resin and zinc phosphate cements were evaluated. Single-rooted extracted human teeth with crowns (n = 120), removed at the cementoenamel junction, were randomly divided into 4 groups of 30 samples each. Different post lengths were luted with either Flexi-Flow or zinc phosphate. Each sample was placed into a specialized jig and on a tensile testing machine with a crosshead speed of 2 mm/min, applied until failure. The effect of different posts and cements on the force required to dislodge the dowels was evaluated with multiple analyses of variance (ANOVA). One-way ANOVA with ScheffÃ© contrast was applied to determine the effect of different post lengths on the retentive failure of posts luted with the 2 agents.Flexi-Flow reinforced composite resin cement significantly increased retention of ParaPost and Dentatus dowels (P<.001) compared with zinc phosphate. One-way ANOVA revealed no statistically significant difference (P>.05) between mean retention of both dowels luted with Flexi-Flow for all posts length used (5 mm = 8 mm = 10 mm). Mean retention values of the groups luted with zinc phosphate showed a statistically significant difference (P<.001) for the different post lengths (10 > 8 > 5 mm). Parallel-sided ParaPost dowels demonstrated a higher mean retention than tapered Dentatus dowels (P<.001).In this study, Flexi-Flow reinforced composite resin cement compensated for the reduced length of shorter parallel-sided ParaPost and tapered Dentatus dowels.
