Abstract
In this paper, humic acid (HA), known to play a large role in the binding and transport of pesticides in soil, was immobilized on a chromatographic support. Then, the association of some herbicides and rodenticides with the main soil component HA was examined using this novel chromatographic column. It appeared that HA has a lower affinity for neutral than for charged pesticides. Moreover, the influence of various parameters was investigated on the pesticide retention in order to providevaluable information about both the binding mechanism and the utilization conditions of the HA column. For all the pesticides studied, a change was clearly vizualized in the HA-pesticide association mechanism at a critical value of the Na+ concentration in the bulk solvent, x(c), equal to 0.6 M. Around this value, the HA structure balanced between a flexible linear conformation for x < x(c) and a random coil form for x > x(c). This work confirmed the conformation change on HA immobilized on silica. As well, only for the charged pesticides, it was clearly pointed out that below a Na+ concentration equal to 0.3 M, the pesticide binding to HA decreased when the salt concentration was enhanced due to an ion pair formation and a competition effect between the sodium cation and pesticide to bind to the HA molecule. Furthermore, it was established that the HA column was stable during an extended period of time, indicating that the HA column could soon become very attractive to determine the risk assessment of pesticides.

Abstract
The mechanisms of (i) the binding of two sex-hormones (i.e. progesterone and beta-estradiol) to human serum albumin (HSA) and (ii) the progesterone displacement of its HSA binding cavity by beta-estradiol were studied by biochromatography using three different methods. In the first time, zonal elution method was used to prove the direct competition effect between the two sex-hormone. In the second time, the competition effect between beta-estradiol and progesterone to bound on the same HSA site was analysed by the competitive bi-Langmuir approach. Finally, the thermodynamic data of these two binding processes were studied. The Gibbs free energy value (Delta(approximately)G degrees) of the displacement equilibrium was negative demonstrating that beta-estradiol displaced progesterone of its HSA binding cavity. Moreover, the effect of two chloride modifiers (i.e. Na(+), Mg(2+)) on these two binding processes were analysed. Results showed that in the salt biological concentration ranges, the Mg(2+) cation enhanced strongly the bioavailable progesterone, whereas the Na(+) cation interacted slowly on the progesterone displacement of its HSA binding site by beta-estradiol. This study showed that it must be useful to carry out more in vivo test on the magnesium supplementation effect for women who suffer from estrogen dominance syndrome.

Abstract
Phytoestrogens constitute a promising alternative in the treatment of diseases associated with menopause. Nevertheless, the lack of data concerning their pharmacology and their toxicology requires use precautions. After reminding the pharmacology of estrogen receptors, this review outlines the estrogenicity and the therapeutic potentialities of phytoestrogens according to their structure.

Abstract
The retention mechanism for a series of D,L-dansyl amino acids in high-performance liquid chromatography is investigated using a teicoplanin stationary phase and hydroxypropyl-beta-cyclodextrin (HP-beta-CD) as the mobile phase additive (0-16mM). A theoretical treatment is developed to determine the HP-beta-CD influence on the equilibrium between the teicoplanin phase and the aqueous medium, respectively. From the experimental data, the association constants of the D,L-dansyl amino acids-HP-beta-CD inclusion complexes are determined and discussed in relation to the enantiomer structure. A thermodynamic study confirms that both the retention and complexation mechanisms are independent of the dansyl amino acid molecular structure and its absolute carbon configuration.

Abstract
In this paper, a new and efficient method for synthesis of phloroglucinol with an overall yield of 60% was described. As well, the phloroglucinol association on an immobilized human serum albumin (HSA) column was analyzed in biochromatography by the determination of its Langmuir distribution isotherms. The role of the magnesium cation Mg2+ on the phloroglucinol-HSA binding process was as well analyzed. The results showed that in the Mg2+ concentration range (0.7-2 mM) (including its biological concentration range, i.e. 0.75-0.90 mM), increasing the Mg2+ concentration increased the fraction of free phloroglucinol (not linked with HSA) and thus its biological effect.

Abstract
The role of the Mg2+ cation on antihypertensive molecule binding on human serum albumin (HSA) was studied by affinity chromatography. The thermodynamic data corresponding to this binding were determined for a wide range of Mg2+ concentrations (c). For the nifedipine molecule, an increase in the Mg2+ concentration produced a decrease in binding due to a decrease in the electrostatic interactions. For verapamil and diltiazem, which have the highest solvent accessible surface area, the solute binding on HSA was divided into two Mg2+ concentration regions. For a low c value below c(c) (approximately 1.6 mmol/l), the binding dependence with c was similar to that of nifedipine. For c above c(c) the hydrophobic effect created in the bulk solvent associated with a decrease in the van der Waals interactions between the solute molecule and the HSA implied a decrease in its binding. These results showed that for patients with hypertension, an Mg2+ supplementation during treatment with these antihypertensive molecules can increase the active pharmacological molecule concentration.

Abstract
In high performance liquid chromatography (HPLC) using poly (octadecylsiloxane) as a stationary phase, phosphate buffer as a mobile phase, a series of R-S imidazole derivatives as solutes, and beta-CD (beta-CD) and hydroxypropyl-beta-CD (HP-beta-CD) as chiral selectors, a study on the hydrophobic effect on both the solute complexation with the chiral selector and chiral discrimination mechanisms was carried out by varying the sucrose concentration c in the mobile phase and the column temperature T. An original mathematical treatment was developed to calculate the degree of complexation, rho (the percent of complexed guest solute), and the number of sucrose molecules excluded from both the uncomplexed solute-RP18 stationary phase interface (when the solute transfer occurred) and the solute-CD interface during the complexation process. This number of sucrose molecules was an image of the relative intensity of the hydrophobic effect and the inclusion degree of the solute in the chiral selector. Different Van't Hoff plot shapes of the degree of complexation and sucrose molecule number were observed with beta-CD and HP-beta-CD indicating a change in the solute inclusion and chiral discrimination.

Abstract
When packed columns filled with porous particles are used for the separation of macromolecules, either size exclusion chromatography (SEC), hydrodynamic chromatography (HDC), or a combination of both determine the macromolecule retention mechanism. This paper develops a simple mathematical model to describe a molecular weight calibration graph, which includes both HDC and SEC. There is a transition between the HDC calibration region at higher molecular weights to an SEC region at lower molecular weights. The degree to which SEC and HDC are mixed depends on the particle diameter, the relative size of the pores, and the macromolecule size. In addition, using fractal considerations, the fractal character of the apparent selectivity between two adjacent peaks on the chromatogram is shown. This model constitutes an attractive tool to enhance the expansion of these two chromatographic techniques for the separation of biological or synthetical macromolecules.

Abstract
Novel equations (Guillaume Y. C.; et al. Anal. Chem. 2000, 72, 853) were developed to describe the large double-stranded DNA molecule retention in slalom chromatography (SC). These equations were applied for the first time to model both the "apparent selectivity" and the resolution between two eluted DNA fragments on a chromatogram. A study of the column efficiency corroborated the fact that slalom chromatography is not based on an adsorption or equilibrium phenomenon, but can be attributed to a hydrodynamic phenomenon. Using a combination of the dynamics of DNA fragment progression in the column and fractal considerations, it was shown that the apparent selectivity depends both on the DNA fragment sizes and mobile-phase flow rate and therefore a balance between two hydrodynamic regimes. A chromatographic response function was also used to obtain the most efficient separation conditions for a mixture of DNA fragments in a minimum analysis time. The chromatographic data confirmed that in SC the flow rate can increase or maintain the separation efficiency with an associated decrease in the analysis time. This constitutes an attractive outcome in relation to the classical chromatographic separation.

Abstract
Molecular modeling used to compare 64 immunostimulant compounds with pyrrolie quinolein or purine nuclei has pointed out that a common spatial structure is found in most of the active compounds. An additional study of immunostimulants (levamisole, muramyldipeptide) or immunosuppressive molecules (rapamycin) was performed. A common pharmacophore was found on every studied compound. It was composed of three neighboring electroattractive atoms and a further fourth atom. The favorable conformation of rapamycin for immunosuppressive action, which is not the more stable conformation, could explain the loss of its activity, or those of related macrolides, when some minor chemical modifications are tested. These findings validate the proposed concept and provide a view of the mechanism of action of most of the immunomodulator compounds for preparing novel compounds

Abstract
Stressful events induce responses in the endocrine and immune systems. The authors analysed the influence of repetitive noise stress on peritoneal macrophage oxidative and phagocytic responses. Plasma corticosterone levels were also measured. Different groups of 6- to 8-week-old C57BL/6 male mice were exposed for 1 night (n = 14) and 3 nights (n = 21) to a sound stress of 110 dB in an audiogenic stress chamber. Control animals were submitted to a sham stress for 1 night (n = 13) and 3 nights (n = 17). A marked decrease was observed in the phagocytic response to yeast (P = 3 x 10(-4)) while a mild increase in the oxidative response stimulated by opsonized zymosan was noted only after the 3 night stress (P = 0.02). Corticosterone levels of control and stressed mice did not differ. These results indicate that the stress resulting from repetitive noise causes modifications in peritoneal macrophage activity, and that these changes are dependent on the duration of stress. These functional alterations seem more complex than a simple general suppression or activation.

Abstract
The use of optical fiber in a temperature probe or sensor for optical pyrometry in the 100-1000 °C range is affected by the low thermal stability of classical fibers. We have studied the different sources of perturbations induced by exposure to high temperature. Two specific fibers especially suited for a high-temperature environment were tested and compared. Low (100 °C/min) and very fast (100 °C/s) fiber heating was performed to evaluate its influence on the guided flux and the induced error on temperature measurement. The metallic-coated fiber shows a reproducible temperature error that can be predicted. This important result permits the development of an uncooled fiber probe for temperature monitoring in high-temperature environments such as aerospace engines.

Abstract
A series of 6,8-dioxo-3-thia-1,7-diazabicyclo[3.3.0]octanes and a series of 6,8-dioxo-3-thia-1,7-diazabicyclo[3.3.0]octane 2-spiro derivatives were synthesized from L-(-)-R-cysteine ethyl ester in two steps. The synthetic route involved condensation of the amino acid with an appropriate aldehyde or ketone, then a further condensation of the resultant ethyl thiazolidine-4-carboxylate with an isocyanate or an isothiocyanate. The proliferative response to human lymphocyte mitogen (phytohemagglutinin) was used as a primary screening assay for most of the thiadiazabicyclic compounds in comparison with levamisole. Furthermore, the most active compounds were tested for ability to release soluble receptors (sRIL-2) after mitogenic stimulation of T cells and for ability to activate macrophage oxidative metabolism measured by chemiluminescence. Most compounds were active in all three tests and some showed dose-dependent activity.
