Oryzalin, a dinitroaniline herbicide, was previously reported to bind to plant tubulin with a moderate strengthe interaction (dissociation constant [Kd] = 8.4 [mu]M) that appeared inconsistent with the nanomolar concentrations of drug that cause the loss of microtubules, inhibit mitosis, and produce
Extracts of maize (Zea mays L.) plants contain substances which, in vitro, inhibit an indoleacetic acid (IAA) oxidase enzyme from maize. The extracts can be freed of inhibitors by dialysis or by passage through columns of polyvinylpyrrolidone powder. Inhibitor-free extracts contain an IAA oxidase
In this randomized and placebo-controlled trial, safety and lipid-lowering effect of fish and corn oils rich in polyunsaturated fatty acids compared with sesame oil that is mainly saturated were studied in 60 hemodialysis cases allocated to 4 different treatment groups. Each group (n = 15) received
Flow-injection Donnan dialysis is demonstrated for the extraction of lead in sweeteners using flame atomic absorption spectroscopy (FAAS). For spiked concentrations in the low microgram per gram range, recoveries were greater than 90%, and the relative standard deviation was typically less than 10%
Because of excessive eltrafiltration (UF), the RP 6 dialyzer requires a closed recirculating dialyzate delivery system. The purpose of this study is to present the characteristics of the RP 6 dialyzer on a single needle system which programs the UF rate of this dialyzer. The single needle system
Since fish oil has been reported to reduce platelet aggregability, to reduce blood viscosity by increasing red blood cell deformability and to lower blood pressure, we studied the effect of dietary supplementation with fish oil on the occurrence of adverse effects in patients receiving recombinant
BACKGROUND
A low serum albumin concentration < 3.8 g/dL, a marker of malnutrition-inflammation complex syndrome, is observed in approximately half of all maintenance hemodialysis (MHD) patients in the United States and is strongly associated with increased mortality.
OBJECTIVE
We hypothesized that a
A novel supersaturable self-emulsifying drug delivery system (S-SEDDS) of cyclosporine A (CyA)-a poorly water-soluble immunosuppressant-was constructed in order to attain an apparent concentration⁻time profile comparable to that of conventional SEDDS with reduced use of oil, surfactant, and
Extracts of immature kernels of Zea mays catalysed the synthesis of indol-3-ylacetyl-myo-inositol galactoside from indol-3-ylacetyl-myo-inositol and UDP-galactose. Addition of 2-mercaptoethanol was required for stability of the catalytic activity during dialysis. The enzyme could be fractionated
The formation of Cu-alginate complexes and the impact of free or bound copper on the oxidative stability of model water/oil mixtures containing edible sunflower or corn oil were examined. Equilibrium dialysis showed that copper binding capacity of alginate increased proportionally with copper
The properties of homoserine dehydrogenase (EC 1.1.1.3) isolated from shoots of young etiolated seedlings of Zea mays L. var. earliking can be reversibly altered by dialysis against an appropriate buffer. Treatment with 500 millimolar potassium phosphate buffer (pH 7.5) in the absence of l-threonine
The sulfonylurea herbicide chlorsulfuron and the imidazolinone herbicide imazaquin were shown to be noncompetitive and uncompetitive inhibitors, respectively, of purified acetolactate synthase from barley (Hordeum vulgare L.) with respect to pyruvate. From double-reciprocal plots of the
The absorption profile of phenytoin Na emulsion were examined compared to that of phenytoin suspension after oral administration in the rat. The corn oil-in-water emulsion, particle size of 184+/-57.8 nm, was prepared using a microfludizer, and phenytoin Na added by shaft homogenizer. The phenytoin
Three apparently different glucosephosphate isomerases are found in the developing seeds of maize (Zea mays L.). Glucosephosphate isomerase I is found in both the endosperm and embryo. It is separable by column chromatography from glucosephosphate isomerase II of the developing endosperm and
OBJECTIVE
This study sought to examine the effect of n-3 supplementation on lipoprotein(a) (Lp(a)) levels in end-stage renal disease (ESRD) patients undergoing chronic hemodialysis.
METHODS
The present study was conducted using a double-blind, permuted-randomized, controlled experimental
