BACKGROUND Haemofiltrate reinfusion (HFR) is a form of haemodiafiltration (HDF) in which replacement fluid is constituted by ultrafiltrate from the patient 'regenerated' through a cartridge containing hydrophobic styrene resin. Bicarbonate-based dialysis solutions (DS) used in routine haemodialysis and HDF contain small quantities of acetate (3-5 mMol/L) as stabilizing agent, one of the major c...

Metabolism of acetate from colonic fermentation was investigated in dogs. Beagle dogs (n = 9) were fed a control diet for 17 d followed by a 3% inulin-enriched diet (from chicory) for 4 and 21 d. On 3 occasions, the dogs were administered simultaneously infusions of [1-(13)C]acetate i.v. and [1,2-(13)C(2)]acetate intrarectally. Peripheral acetate concentration and turnover did not change over t...

Measurement of 13C-labeled fatty acid oxidation is hindered by the need for acetate correction, measurement of the rate of CO2 production in a controlled environment, and frequent collection of breath samples. The use of deuterium-labeled fatty acids may overcome these limitations. Herein, d31-palmitate was validated against [1-13C]palmitate during exercise. Thirteen subjects with body mass ind...

Introduction.-It has been shown earlierl 2 that the synthesis of the isoprenoid, rubber, by a rubber-bearing plant, guayule (Parthenium argentatum), involves acetate as an, intermediate. Not only does the administration of acetate to this plant result in a net increase in the amount of rubber formed, but, in addition, rubber synthesized by plants supplied with doubly C"4-labeled acetate possess...

OBJECTIVE To evaluate the clinical and hormonal response of topically applied cyproterone acetate, oral cyproterone acetate, and placebo lotion in women with acne. DESIGN Placebo-controlled, randomized study. SETTING Patients were recruited from the Institute of Endocrine Cosmetics, Vienna, Austria. PATIENTS Forty women with acne. INTERVENTIONS Treatment with oral medication consisting ...

The dynamic structure factor is given by F (k, ω) = 1 2π ∞ −∞ S(k, t)e iωt dt (1) with the intermediate scattering S(k, t) = G(r, t)e −i k r d r (2)

The present study was designed to evaluate the antioxidant activity of 5 organic solvent extracts (petroleum ether, n-hexane, chloroform, ethyl acetate and methanol) of wheat grains, 3, 5 and 7 days old wheat seedlings. To determine the antioxidant activity of five extracts of four different samples, 1,1-diphenyl-2-picrylhydrazyl and 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) radica...

Learning can rely on stimulus quality, stimulus intensity, or a combination of these. Regarding olfaction, the coding of odour quality is often proposed to be combinatorial along the olfactory pathway, and working hypotheses are available concerning short-term associative memory trace formation of odour quality. However, it is less clear how odour intensity is coded, and whether olfactory memor...

AIMS   This work aimed to characterize microbial tolerance to 1-ethyl-3-methylimidazolium acetate ([C2mim][OAc]), an ionic liquid that has emerged as a novel biomass pretreatment for lignocellulosic biomass. METHODS AND RESULTS   Enrichment experiments performed using inocula treated with [C2mim][OAc] under solid and liquid cultivation yielded fungal populations dominated by Aspergilli. Ionic...

We study the solvation properties of the ionic liquid 1-ethyl-3-methylimidazolium acetate ([EMIM](+)[ACE](-)) and the resulting dynamic behavior for differently charged model solutes at room temperature via atomistic molecular dynamics (MD) simulations of 300 ns length and 200 ns equilibration time. The solutes are simple model spheres which are either positively or negatively charged with a va...
