Kinetic Characterization of Secretory Transport of a New Ciprofloxacin Derivative (CNV97100) across Caco-2 Cell Monolayers**This work has been submit…
2002
The kinetics of transport of a new fluoroquinolone antibiotic (CNV97100) and its analogs were characterized using the Caco-2 cell culture model. Unidirectional permeabilities of these analogs were greater (p < 0.05) than that of ciprofloxacin. The absorptive permeabilities (P(AB)) of 4'-N-substituted analogs (CNV97101-104) were 400-600% greater, whereas the secretory permeability (P(BA)) was 25-80% greater than unsubstituted analogs because CNV97101-104 were poor substrates for efflux transporters (efflux ratio approximately 1). The transport of compounds without 4'-N-substitution (i.e., ciprofloxacin and CNV97100) favored secretion (efflux ratio approximately 4). Further characterization o…
368 Growth of Infant Fed Starter Formula Containing Prebiotics or Symbiotic
2010
Objective: To assess growth of infants fed starter formula supplemented with either prebiotics or symbiotic. In addition, gut microbiota was studied. Methods: Healthy, full term newborns (n= 240) were enrolled before the 14th day of their life and randomly assigned between 3 exclusively formula fed groups: starter IF, starter IF + prebiotics (CMOS+GOS), starter IF + prebiotics (CMOS+GOS) and probiotics (BL999 + LPR). Growth was assessed by body weight gain during 4 months. Gut microbiota profile was examined by measuring fecal counts in Bifidobacteria, Lactobacilli, Enterobacteria, Clostridium at 2 months of age. Incidence of morbidity was appraised. Results: Non inferiority in growth was e…
Optimization of alkali pretreatment to enhance rice straw conversion to butanol
2021
Abstract The use of rice straw (RS) was enhanced to produce biobutanol as biofuel, for which the NaOH pretreatment was optimized by considering the butanol-biomass ratio that quantify the mass balance efficiency of the three sequential stages of the process: pretreatment, enzymatic hydrolysis and fermentation by Clostridium beijerinckii. The optimum point (solid loading of 5% w/v with 0.75% w/v NaOH at 134 °C for 20 min) of the best cost-wise option yielded an enhanced biomass use of 77.6 g kg RS−1. A maximum butanol titer of 10.1 g L−1 was reached after 72 h of fermentation with the complete uptake of glucose and nearly complete uptake of xylose. The NaOH concentration was the most influen…
Thermophilic hydrogen production from cellulose with rumen fluid enrichment cultures: Effects of different heat treatments
2011
Elevated temperatures (52, 60 and 65 °C) were used to enrich hydrogen producers on cellulose from cow rumen fluid. Methanogens were inhibited with two different heat treatments. Hydrogen production was considerable at 60 °C with the highest H2 yield of 0.44 mol-H2 mol-hexose -1 (1.93 mol-H2 mol-hexose-degraded-1) as obtained without heat treatment and with acetate and ethanol as the main fermentation products. H2 production rates and yields were controlled by cellulose degradation that was at the highest 21%. The optimum temperature and pH for H2 production of the rumen fluid enrichment culture were 62 °C and 7.3, respectively. The enrichments at 52 and 60 °C contained mainly bacteria from …
In vitro enterococcus faecalis biofilm formation on five adhesive systems
2011
Objective: To determine the E. faecalis biofilm formation on the surface of five adhesive systems (AS) and its relationship with roughness. Study Design: The formation of E. faecalis biofilms was tested on the surface of four dual-cure AS: AdheSE DC, Clearfil DC Bond, Futurabond DC and Excite DSC and one light-cure antimicrobial AS, Clearfil Protect Bond, after 24 hours of incubation, using the MBEC high-throughput device. Results: E. faecalis biofilms grew on all the adhesives. The least growth of biofilm was on Excite DSC, Clearfil Protect Bond, and the control. Futurabond DC resulted in the greatest roughness and biofilm amount. There was a close relationship between the quantity of biof…

Dourges : projet d'extension de la plateforme multimodale Delta 3 : rapport de diagnostic
2014
Le diagnostic archéologique réalisé en amont de l'extension de la plateforme Delta 3 a permis de compléter et d'approfondir les connaissances concernant le territoire de Dourges. Les vestiges mis au jour couvrent plusieurs millénaires et concernent les périodes protohistoriques (âge du Bronze et Hallstatt) et historiques (de l'Antiquité jusqu'à l'époque moderne). Pour les périodes protohistoriques, il s'agit d'éléments épars qui ne semblent pas constituer à proprement parler un site. Cependant, des signes ténus d'occupation sont avérés dans ce secteur dés l'âge du Bronze ainsi que durant le premier âge du Fer. L'absence de vestiges de certaines périodes, particulièrement celles du second âg…
Izolacja oraz prawa i obowiązki skazanych odbywających karę pozbawienia wolności w zakładach karnych zamkniętych, o których mowa w art. 90 Kodeksu ka…
2020
Wykonywanie kary pozbawienia wolności związane jest z izolowaniem skazanych w zakładach karnych odpowiedniego typu. Warunki w zakładzie typu zamkniętego zostały tak określone, że prawa skazanych ograniczono głównie ze względu na konieczność utrzymania ładu i porządku wewnętrznego. Dlatego też takich skazanych jedynie uprawniono do przebywania w otwartych celach mieszkalnych, do zatrudnienia poza zakładem, do korzystania z zajęć kulturalnych i sportowych i nauki, do korzystania z własnej bielizny, obuwia i odzieży oraz widzeń (na określonych surowych zasadach). Z drugiej strony skazanych z tego typu zakładów zobowiązano do znoszenia ograniczeń w zakresie poruszania się po terenie zakładu or…
Reading the Web—Students' Perceptions about the Internet
2006
This study explores the perceptions of Finnish 15‐year‐olds on the advantages and disadvantages of the Internet. The data, students' written responses (N = 3112), were gathered in the context of the OECD Programme for International Student Assessment (PISA) in the spring of 2000 as a national option. The data were analysed by close reading and using the Atlas.ti application for coding. Students regard easy access to a variety of current information as the most important advantage of the Internet. Finding new friends and chatting with old ones was also emphasised, as well as the downloading capacities of the Internet. Although problems of finding reliable and truthful information were recogn…
