- Abstract
-
Carbamazepine and imipramine are drugs that have significant binding to human serum albumin (HSA), the most abundant serum protein in blood and a common transport protein for many drugs in the body. Information on the kinetics of these drug interactions with HSA would be valuable in understanding the pharmacokinetic behavior of these drugs and could provide data that might lead to the creation of improved assays for these analytes in biological samples. In this report, an approach based on peak profiling was used with high-performance affinity chromatography to measure the dissociation rate constants for carbamazepine and imipramine with HSA. This approach compared the elution profiles for each drug and a non-retained species on an HSA column and control column over a board range of flow rates. Various approaches for the corrections of non-specific binding between these drugs and the support were considered and compared in this process. Dissociation rate constants of 1.7 (±0.2) s―1 and 0.67 (±0.04)s―1 at pH 7.4 and 37 C were estimated by this approach for HSA in its interactions with carbamazepine and imipramine, respectively. These results gave good agreement with rate constants that have determined by other methods or for similar solute interactions with HSA. The approach described in this report for kinetic studies is not limited to these particular drugs or HSA but can also be extended to other drugs and proteins.

- Abstract
-
Focus of this work was the development and characterization of a new immobilized enzyme reactor (IMER) containing human recombinant butyrylcholinesterase (rBChE) for the on-line kinetic characterization of specific, pseudo-irreversible and brain-targeted BChE inhibitors as potential drug candidates for Alzheimer's disease (AD). Specifically, a rBChE-IMER containing 0.99 U of covalently bound target enzyme was purposely developed and inserted into a HPLC system connected to a UV-vis detector. Selected reversible cholinesterase inhibitors, (-)-phenserine and (-)-cymserine analogues, were then kinetically characterized by rBChE-IMER, and by classical in solution assays and their carbamoylation and decarbamoylation constants were determined. The results support the elucidation of the potency, inhibition duration, mode of action and specific structure/activity relations of these agents and allow cross-validation of the two assay techniques.

- Abstract
-
L'acétylcholinestérase est une enzyme très rapide, essentielle à la neurotransmission cholinergique. Elle est la cible de toutes les molécules actuellement utilisées dans le traitement de la maladie d'Alzheimer, et les progrès à venir dans la modulation de son activité ont besoin d'une connaissance plus fine de sa structure et de sa dynamique. L'exploration du paysage conformationnel d'une protéine par la méthode de cristallographie aux rayons X réclame l'utilisation d'astuces expérimentales afin de dépasser la nature généralement statique des résultats obtenus. Nous présentons ici trois approches expérimentales ayant permis d'obtenir des informations structurales sur la dynamique de l'acétylcholinestérase, lesquelles sont importantes, puisque pertinentes, pour le structure-based drug-design.

- Abstract
-
Different model food systems were made with iota- and kappa-carrageenans. Their viscoelastic characteristics were determined and four different systems were classified according to their gel strength by a sensory panel. The sensory results were in total agreement with the rheological parameters (storage and loss modulus). Flavour molecules from different chemical classes and with different chain lengths for the same chemical class were then incorporated in two of the most different systems. These samples were compared for their ortho- and retronasal intensities. No significant difference was perceived in odour intensity, except for ethyl hexanoate, which was found to be retained by iotacarrageenans. Nevertheless, in-mouth aroma perception was significantly different between the two systems. Aroma was perceived more intensely in the less firm system. The release kinetic results are interpreted in terms of partition and mass transfer coefficients. Sensory differences are not totally explained by physicochemical results, which suggests that interactions between senses may occur.

- Abstract
-
The long-term persistence of five volatiles in the breath was studied to determine the effects of respiration and the physical properties of each of the volatiles. The long-term persistence of each of the volatiles in the breath was modelled successfully and used to show that the breath volatile concentration 1 min after consuming the solution was greater when panelists exhaled at a slower rate. The air-water partition coefficient (Kaw) was influential in controlling the initial stages of persistence; compounds with a higher Kaw were found to decay at a much faster rate than compounds with a low Kaw. The decay rate during the later stages was constant for all the volatiles, which indicates that the rate-limiting factor during the later stages of persistence does not depend on the individual properties of the volatiles.

This study examined the effect of ageing on the swing phase mechanics of young and elderly gait. Sagittal plane marker trajectories and force plate data were collected while 10 young (24.9 ± 0.9 years) and eight elderly (68.9 ± 0.4 years) subjects walked at their preferred walking speeds. Comparison between young and elderly gait was made for a range of spatial-temporal, kinematic and kinetic variables with emphasis given to identifying possible differences at toe-off, minimum metatarsal-phalangeal joint clearance and heel contact. In order to control for the confounding effect of gait velocity on the dependent variables, a multivariate analysis of covariance was used to identify differences between the young and elderly subjects due to age. In contrast to studies that have reported lower preferred walking speeds in the elderly compared to the young [J.O. Judge, R.B. Davis III, S. Ounpuu, Step length reductions in advanced age: the role of ankle and hip kinetics, Journal of Gerontology: Medical Sciences 51 (1996) M303-312; D.C. Kerrigan, M.K. Todd, U. Della Croce, L.A. Lipsitz, J.J. Collins, Biomechanical gait alterations independent of speed in the healthy elderly: evidence for specific limiting impairments, Archives of Physical and Medical Rehabilitation 79 (1998) 317-322], no differences in walking speed nor in the spatial-temporal variables that determine walking speed were detected. The elderly were however, found to have a greater hip extension moment at the time of minimum metatarsal-phalangeal joint clearance, and a significantly higher anterior-posterior velocity heel contact velocity that was linked to a significantly higher shank and foot angular velocity at heel contact. Since many gait variables are highly correlated with walking speed [C. Kirtley, M.W. Whittle, R.J. Jefferson, Influence of walking speed on gait parameters, Journal of Biomechanical Engineering 7 (1985) 282-288; D.A. Winter, Biomechanical motor patterns in normal walking, Journal of Motor Behaviour 15 (1983) 302-330], differences between young and elderly gait found in the present study may therefore be attributed to ageing, rather than a secondary effect of differences in gait velocity.

- Abstract
-
A quantitative model of pheromone-receptor interaction and pheromone deactivation, the supposed rate-limiting processes underlying the receptor potential kinetics, is worked out for the moth Antheraea polyphemus. In this model, the pheromone interacts with the receptor molecule while bound to the reduced form of the pheromone binding protein. The receptor molecules-besides their receptor function-catalyze the observed shift of the pheromone-binding protein from the reduced to the oxidized form (Ziegelberger, G., Eur. J. Biochem., 232, 706-711, 1995), which deactivates the pheromone bound to pheromone binding protein. With the following parameters, the model fits morphological, radiometric, electrophysiological and biochemical data: a maximum estimate of 1.7 x 107 receptor molecules/cell (with 40 000 units/μm2 of receptor cell membrane), rate constants k1 = 0.2/(s. μM) for the association, k2 = 10/s for the dissociation of the ternary complex of binding protein, pheromone and receptor, and k3 = 10/s for the deactivation via the redox shift. With these parameters, the duration of elementary receptor potentials elicited by single pheromone molecules (∼50 ms) reflects the lifetime of the ternary complex, τ = 1/(k2 + k3). The receptor occupancy produced by the model for threshold stimuli fits the sensitivity of the receptor cell to single pheromone molecules.

- Abstract
-
Both for Aplysia and Drosophila a key role in the molecular mechanism of learning and memory processes has been assigned to the cAMP cascade. In any learning process a short-time stimulus has to be translated into long-lasting changes. The molecular correlate must be a cascade of biochemical reactions with different kinetics, functionally interlinked and operating in overlapping time ranges. Biochemical studies in Drosophila have led to the suggestion that one of these steps is a proteolytic modification of the regulatory subunits of protein kinase A. A quantitative analysis of the relaxation kinetics of a system of protein kinase A, phosphatases and a calcium-dependent protease can give an image of essential characteristics of learning behaviour in Drosophila.
