Abstract
We examined large-scale patterns of morphology, genetic structure and ecological correlates of Fraxinus excelsior and the closely related species Fraxinus angustifolia in France, in order to determine the degree of hybridization between them. We sampled 24 populations in two putative hybrid zones (Loire and Saône), and five control populations of each species. We measured foliar characteristics of adult trees and used five nuclear microsatellites as molecular markers. Canonical discriminant analysis indicated that the two species differ in morphology, but that intermediate types are common in the Loire region but less frequent in the Saône region. Bayesian population assignment identified one F. angustifolia and two F. excelsior gene pools. Most Loire individuals clustered genetically with the F. angustifolia gene pool. In contrast, the Saône region presented individuals belonging mostly to F. excelsior pools, although the F. angustifolia type was frequent in certain populations. The lowest F(ST) values were found between the Loire and F. angustifolia controls that also exhibited no significant isolation by distance. The proportion of the F. angustifolia gene pool in each locality was negatively correlated with winter temperatures, suggesting that a cold climate may be limiting. Hybridization is probably favoured by the intermediate climatic conditions in the Loire region that allow both species to occur, but is somewhat hampered by the harsher winters in the Saône area where morphological introgression has apparently not yet occurred.

Abstract
Studies in nonhuman primates indicate that changes in the thickness and integrity of the vaginal epithelium affect the transmission rates of HIV-1, but few studies have examined the normal variations that may occur in the vagina of normal macaques as a result of aging or changes in the menstrual cycle. This study was conducted to determine if differences occur in the thickness of the vaginal mucosa with age or menses. Vaginal mucosal thickness was compared in 46 rhesus macaques grouped as juvenile (1-3 years old), mature cycling (3-21 years old), and geriatric (> 21 years old). Epithelia of mature cycling macaques were also compared at different stages of the menstrual cycle. Older females (> 21 years) had the thinnest and least keratinized epithelium of all groups, followed by the youngest females (< 3 years). The vaginal epithelium was also thinner in cycling macaques during menses compared to the follicular stage. In addition, young, geriatric, or cycling macaques during menses had minimal keratinization. We hypothesize that normal physiologic changes in the vaginal epithelium of women occur with age and menses, which may affect a woman's susceptibility to HIV-1 transmission and other sexually transmitted diseases. Also, age and menstrual cycle should be considered when designing vaginal transmission experiments in rhesus macaques.

Abstract
Cytosine-phosphate-guanine class C (CpG-C) immunostimulatory sequence oligodeoxynucleotides (ISS-ODNs) activate human B cells and dendritic cells (DCs), properties that suggest potential use as a novel adjuvant to enhance vaccine efficacy. After demonstrating that the CpG-C ISS-ODN C274 activates macaque DCs, we examined in vitro activation of macaque B cells by C274 as a prelude to evaluation of this molecule as an adjuvant in the testing of candidate human immunodeficiency virus vaccines in the rhesus macaque-simian immunodeficiency virus (SIV) model. C274 induced macaque CD20(+) B cells to proliferate more strongly than CD40 ligand or CpG-B ISS-ODN. C274 enhanced B cell survival; increased viability was most evident after 3-7 days of culture. Increased expression of CD40, CD80, and CD86 by B cells was apparent within 24 h of exposure to C274 and persisted for up to 1 week. C274-stimulated, B cell-enriched and peripheral blood mononuclear cell suspensions from naïve and immunodeficiency virus-infected monkeys secreted several cytokines [e.g., interleukin (IL)-3, IL-6, IL-12, interferon-alpha] and chemokines [e.g., monocyte chemoattractant protein-1/CC chemokine ligand 2 (CCL2), macrophage-inflammatory protein-1alpha/CCL3, IL-8/CXC chemokine ligand 8]. In comparison, exposure of macaque B cells to SIV had minimal impact on surface phenotype, despite inducing cytokine and chemokine production in cells from infected and uninfected animals. These observations emphasize the need to identify strategies to optimally boost immune function, as immunodeficiency viruses themselves only partially activate B cells and DCs. The ability of C274 to stimulate B cells and DCs in healthy and infected monkeys suggests its possible use as a broad-acting adjuvant to be applied in the rhesus macaque model for the development of preventative and therapeutic vaccines.

Abstract
Notwithstanding the progress recently made in immunology and virology, there is yet no effective, specific treatment for the common cold. Symptomatic treatment is minimally effective. An anecdotal report of rapid clearing of the common cold of recent onset after intranasal application of imiquimod in several subjects by one of the authors, made us test the hypothesis that this treatment works through the secretion of interferon by the nasal mucosa. We decided to do an animal study in primates (Indian Macaca Mulata): 5 treatment and 3 control animals were used. Imiquimod or placebo was massaged into the nares of the animals and periodic samples of post-nasal fluid were taken and measurements for Interferon alpha (IFNalpha) and Tumor Necrosis Factor alpha (TNFalpha) were made by ELISA methods, and kinetic studies. mRNA IFNalpha was also isolated and analyzed by quantitative competitive RT-PCR. The internal standard was constructed to be complementary to and compete with oligonucleotide primers and for amplification of target sequences. One intranasal application of imiquimod rapidly (1-4 Hours) induced high levels of mRNA for IFNalpha, and minimal levels in the control animals. Rapid induction of INFalpha, and proportional increase of TNFalpha sustained for 4 and 6 hours respectively were noted. No adverse reactions to treatment were found in macaques during this short period of intranasal imiquimod usage (except in one macaque with a short period of lacrimation). No animal had cytotoxic effects when examined at 6 hr, 12 hr, 24 hr or 48 hr, except one animal, which had an episode of lacrimation for 6 hr post treatment. Thus both safety and efficacy of short treatment with imiquimod is proven in this animal model. Proof of principle for intranasal treatment of the common cold with imiquimod is shown. We think that this work will encourage a number of double blind clinical trials to confirm the effectiveness of the intranasal treatment of the common cold with imiquimod.

Abstract
Common ash is a temperate forest tree with a colonizing behaviour, a discontinuous spatial distribution and a peculiar and poorly known mating system. Microsatellite markers were used to study the genetic structure in natural populations of common ash. Twelve populations located in northeastern France were analysed at five loci. Levels of genetic variability within and among stands were estimated for the seedling and adult stages. As expected for a forest tree, our results reveal high levels of intrapopulation diversity and a low genetic differentiation between stands. However, a general and significant heterozygote deficiency was found, with a mean F(IS) of 0.163 for the seedlings and of 0.292 for the adult trees. The different explanations for such an excess homozygosity are discussed: a nonMendelian inheritance of alleles, the presence of null alleles, a Wahlund effect and assortative mating.

Abstract
OBJECTIVES Present the method used to elaborate and formalize current scientific knowledge to provide physicians with tools available on the Internet, that enable them to evaluate individual patient risk, give personalized preventive recommendations or early screening measures. METHODS The approach suggested in this article is in line with medical procedures based on levels of evidence (Evidence-based Medicine). A cyclical process for developing recommendations allows us to quickly incorporate current scientific information. At each phase, the analysis is reevaluated by experts in the field collaborating on the project. The information is formalized through the use of levels of evidence and grades of recommendations. GLIF model is used to implement recommendations for clinical practice guidelines. RESULTS The most current scientific evidence incorporated in a cyclical process includes several steps: critical analysis according to the Evidence-based Medicine method; identification of predictive factors; setting-up risk levels; identification of prevention measures; elaboration of personalized recommendation. The information technology implementation of the clinical practice guideline enables physicians to quickly obtain personalized information for their patients. Cases of colorectal prevention illustrate our approach. CONCLUSIONS Integration of current scientific knowledge is an important process. The delay between the moment new information arrives and the moment the practitioner applies it, is thus reduced.

Abstract
A model representing the synthesis process of 4A zeolite from wastes of aluminum finishing plants was obtained and validated through statistical tests. From this model, the optimum values for the molar ratios SiO2/ Al2O3, Na2O/SiO2 and H2O/Na2O, which define the type and quality of the synthesized zeolite, were estimated for the use of these wastes as raw material. The obtained zeolites could be used as water softeners in the formulation of detergents. The resulting liquors could be reused in the cleaning of the extrusion matrices used for aluminum profiles or recycled for new zeolites synthesis.

Abstract
We have followed the transmission of Ophiostoma ulmi s.l. chromosome length polymorphisms (CLPs) into the F2 generation to determine the reproducibility of a genome rearrangement culminating in the conversion of a 1.0 Mb chromosome into a 800 kb chromosome. The 1.0 Mb chromosome in strain CESS16K is thus far unique among O ulmi s.l. wild-type strains, as no other wild-type strains have been observed with chromosomes smaller than 2.3 Mb. It has been previously shown that the 1.0 Mb chromosome is mitotically stable, carries at least one normally expressed gene, and is transmitted through meiosis. In this study, a series of crosses were performed to further elucidate the pattern of inheritance of the 1.0 Mb chromosome and the process of conversion of the 1.0 Mb species to 800 kb. In crosses where the 1.0 Mb chromosome was allowed to pair with itself or with the 800 kb chromosome, all progeny inherited a copy of the 1.0 Mb or 800 kb form, further demonstrating the A-type nature of these small chromosomes. When a cross was repeated between the strains CESS16K (1.0 Mb chromosome) and FG245Br-O (no 1.0 Mb or 800 kb chromosome), the occurrence of a 800 kb chromosome was observed in 9% of the progeny. A reciprocal cross between an 800 kb strain and a strain with no 800 kb or 1.0 Mb chromosome was conducted, and a progeny strain containing a 1.0 Mb chromosome was recovered. The reproducibility and reciprocality of the 1.0 Mb to 800 kb chromosome conversion demonstrates that meiotic processes are responsible for this CLP, and that O. ulmi s.l. strains with various divergent genome architectures can remain sexually compatible.

Abstract
In 1981, a protocol was developed at the Institute Gustave-Roussy, utilizing combined interstitial hyperthermia and brachytherapy, to treat recurrent tumors in previously irradiated areas. This protocol consisted of interstitial hyperthermia, 44 degrees C for 45 minutes, followed immediately by iridium 192 curietherapy, delivering 30 Gy in 2 or 3 days to the tumor volume. Fourteen implantations have been performed in 11 patients. Complete eradication of tumor has been achieved thus far in 10 cases. Two patients were not evaluable because of rapid death resulting from diffuse metastases, and two patients demonstrated a partial response (greater than 50% tumor reduction). Treatment has been generally well tolerated despite prior high dose irradiation. There has been only one serious complication-a large area of painful necrosis following retreatment of a recurrent floor of mouth carcinoma. Special "metallic-plastic" tubes were developed to improve tissue tolerance. We were able to document that a high and homogeneous temperature could be delivered throughout the tumor volume. The technical innovations, and the techniques of implantation and temperature documentation are described below.

Abstract
Spontaneous spleen rupture during chronic pancreatitis is scarcely seen. About 2 personal cases, the authors study 15 published cases. The spleen break can occur in patients with a known chronic pancreatitis, or with pancreatic signs, or without any symptomatology. Diagnosis is hard: spontaneous spleen break often looks like an acute pancreatitis. The high frequency of associated left pleural effusion is significant. Arteriography is helpful when it is done. Splenectomy, often too late, is the right treatment.

Abstract
From 1968 to 1978 the authors treated 60 hydatid cysts of the liver. Echotomography and computerised axial tomography showed the topography of the cyst. However, coelio-mesenteric arteriography and cavography are essential before any kystectomy. In spite of its simplicity, resection of the salient dome of the diaphragm is less often used, owing to the risk of bile leakage and recurrence. Pericystectomy fulfils better our therapeutic objectives. It is more difficult to carry out for there is a risk of hemorrhage. Marsupialisation and hepatectomy are exceptional. Since 1974, 13 pericystectomies out of 15 patients have been carried out, whereas resection of the salient dome was previously the most commonly used procedure (40 out of 45 cases). Only regular immunological follow up is a reliable test of lasting cure.
