BACKGROUND In a previous pilot study comparing insulin glulisine (GLU) with insulin aspart (ASP) administered by continuous subcutaneous insulin infusion (CSII), GLU-treated patients did show a trend toward fewer catheter occlusions compared with ASP-treated patients. Here we performed a randomized open-label, three-way crossover, controlled multicenter study comparing GLU with ASP and insulin ...

Cd from roots of maize was partitioned in seedlings exposed to 3 microM CdSO4 for 1 to 7 d. Most of the root Cd (92-94%) was buffer soluble and provided the classical metal-induced cysteine-rich, high-molecular-weight Cd-binding complex. This complex, however, bound only part of the Cd within the roots, from 19% after 1 d of exposure to 59% by d 7. Three families of peptides formed the Cd-bindi...

The influence of Glu298Asp endothelial nitric oxide synthase (eNOS) polymorphism in exercise-induced reflex muscle vasodilatation is unknown. We hypothesized that nonexercising forearm blood flow (FBF) responses during handgrip isometric exercise would be attenuated in individuals carrying the Asp298 allele. In addition, these responses would be mediated by reduced eNOS function and NO-mediated...

UNLABELLED The carcinogenic glutamic acid pyrolysis products 2-amino-6-methyldipyrido [1, 2-a: 3', 2'-d]imidazole (Glu-P-1) and 2-amino-dipyrido [1, 2-a: 3', 2'-d] imidazole (Glu-P-2), and their N-acetyl derivatives were measured in 24-h urine of individual subjects by high-performance liquid chromatography. These compounds were detected in all urine samples analyzed, although the contents vari...

The first purpose of this study was to investigate whether a glucose (GLU)+fructose (FRUC) beverage would result in a higher exogenous carbohydrate (CHO) oxidation rate and a higher fluid availability during exercise in the heat compared with an isoenergetic GLU beverage. A second aim of the study was to examine whether ingestion of GLU at a rate of 1.5 g/min during exercise in the heat would l...

Glial uptake of neurotransmitter glutamate (GLU) from the extracellular fluid was studied in vivo in rat brain by (13)C NMR and microdialysis combined with gas-chromatography/mass-spectrometry. Brain GLU C5 was (13)C enriched by intravenous [2,5-(13)C]glucose infusion, followed by [(12)C]glucose infusion to chase (13)C from the small glial GLU pool. This leaves [5-(13)C]GLU mainly in the large ...

We present key elements of a proof of a strong form of Arnold diffusion for systems of three and a half degrees of freedom. More exactly, let T3 be a 3-dimensional torus and B3 be the unit ball around the origin in R3. Fix ρ > 0. Our main result says that for a “generic” time-periodic perturbation of an integrable system of three degrees of freedom H0(p) + εH1(θ, p, t), θ ∈ T3, p ∈ B3, t ∈ T = ...

We have analyzed the performance of several widely used density functional theory procedures, namely B-P86, B-PW91, B-LYP, B3-P86, B3-PW91, and B3-LYP, for the E3 set of thermochemical properties. Each of these procedures employs a local density approximation (LDA) functional and a gradient correction for the correlation energy. We find that the VWN3 LDA functional in B-P86, B-PW91, B3-P86, and...

Introduction Licorice could exhibit beneficial effect in the management of insomnia by regulating key modulators such as GABA and serotonin, we therefore aimed to study potentail hypnotic licorice extract, glycyrrhizin (GCZ), on underlying mechanisms. Material methods Mice were randomly grouped a Control group, GCZ (low) (high) group DZP with 8 mice each group. Sleep latency, sleep duration loc...
