Re: Antimicrobial Resistance in More Than 100,000 Escherichia coli Isolates According to Culture Site and Patient Age, Gender, and Location
2011
ABSTRACT Escherichia coli and the antimicrobial pressure exerted on this microorganism can be modulated by factors dependent on the host. In this paper, we describe the distribution of antimicrobial resistance to amikacin, tobramycin, ampicillin, amoxicillin clavulanate, cefuroxime, cefoxitin, cefotaxime, imipenem, ciprofloxacin, fosfomycin, nitrofurantoin, and trimetoprim-sulfametoxazole in more than 100,000 E. coli isolates according to culture site and patient age, gender, and location. Bayesian inference was planned in all statistical analysis, and Markov chain Monte Carlo simulation was employed to estimate the model parameters. Our findings show the existence of a marked difference in…
Nitrofurantoīna kristalizācija un iegūto kristālisko formu ietekmējošie faktori
2017
Nitrofurantoīna kristalizācija un iegūto kristālisko formu ietekmējošie faktori. Trimdale A., darba vadītājs Dr. Chem. Bērziņš A. Maģistra darbs, 60 lappuses, 18 attēli, 13 tabulas, 7 pielikumi, 52 literatūras avoti. Latviešu valodā. Darbā apkopota informācija par cietvielu kristāliskajām formām, kristalizācijas procesu, to ietekmējošajiem faktoriem un kontroles iespējām, kristālisko fāžu un šķīdumu pētījumos izmantotajām metodēm (rentgendifraktometriju, termisko analīzi, protonu kodolmagnētiskās rezonanses spektroskopiju, infrasarkano spektroskopiju, kvantu ķīmiskajiem aprēķiniem) un nitrofurantoīnu. Eksperimentālajā daļā veikta kristalizēšana no dažādiem tīriem organiskajiem šķīdinātājiem…
Evaluation of Aspects Controlling Crystallization of Nitrofurantoin
2019
Nitrofurantoin was crystallized from multiple mixtures of water and organic solvents with and without additives to try to find and identify factors affecting phase obtained in crystallization and provide possible information on crystallization control. Obtained crystals were identified with powder X-ray diffractometry. Crystallization control possibilities were evaluated by using polymer additives and crystallization additives, by also using quantum chemical calculations to investigate the association of nitrofurantoin and additive molecules and calculate Gibbs energy of association.
Reductive and oxidative metabolism of nitrofurantoin in rat liver.
1980
The elimination of nitrofurantoin was studied in the isolated rat liver using a recirculating hemoglobin-free perfusion system. The most rapid clearance of nitrofurantoin (0.1 mM) was found under hypoxia (8 ml/min) or anoxia (11 ml/min) indicating a fast and oxygen-sensitive reductive metabolism. The hepatic elimination of nitrofurantoin under anaerobic conditions apparently is not catalyzed by xanthine oxidase, aldehyde oxidase or cytochrome P-450 as judged from the lack of influence of the inhibitors (0.1 mM) allopurinol, menadione, metyrapone, α-naphthoflavone or of carbon monoxide (50%; v/v). Under aerobic conditions the hepatic clearance of nitrofurantoin is rather low (1 ml/min) indic…
