A 3-D, unsteady, nonlinear, high-resolution model is used to estimate shelf/slope exchanges through Calvi Canyon (NW Corsica, Mediterranean Sea) in various regimes of stratification and wind patterns. To evaluate the alongshore and cross-shore fluxes within the canyon area as well as the water exchanges between the canyon and Calvi Bay, volume transports are computed at the sides of two closed, interconnected boxes encompassing the canyon on the shelf and slope domains. Model results show that water transports between Calvi Bay and the open sea are determined by flow modifications in the canyon area. The mean horizontal flow deviates southwestward upstream of the canyon, generating an onshore transport in the western part of Calvi Bay. Within the canyon, the circulation is cyclonic and is responsible for an offshore transport downstream of the canyon and in the eastern part of the bay. The effect of stratification is shown to limit the vertical extent of the influence of canyon topography so that the alongshore flow above the canyon is quasi-undisturbed in strong stratified conditions, resulting in weak cross-shore exchange. Wind events are shown to be responsible for a strong increase of cross-shore transports between the bay and the canyon area. (C) 2002 Elsevier Science B.V All rights reserved. [less ▲]

Using a first-principles approach based on density-functional theory, the electronic, dielectric, and dynamical properties of the two phases of lithium niobate are studied. In particular, the spontaneous polarization, the optical dielectric tensors, the Born effective charges, and the zone-center phonons are computed. The Born effective charges are found to be significantly larger than the nominal ionic charges of the ions, a feature similar to what is observed in related ABO(3) compounds and attributed to the hybridization between the O 2p and Nb 4d states. The analysis of the zone-center phonons in the paraelectric phase reveals an unstable A(2u) mode to be responsible for the phase transition. The origin of the structural instability is attributed to destabilizing long-range dipolar interactions, which are not fully compensated by stabilizing short-range forces. Finally, the identification of the E modes in the ferroelectric phase, which is still the cause for debates in spite of the numerous experimental and theoretical studies, is discussed and an assignation based on the analysis of the mode-oscillator strengths and the angular dispersion relation of extraordinary phonons is proposed.

We have designed new basic amphiphilic peptides, ppTG1 and ppTG20 (20 amino acids), and evaluated their efficiencies in vitro and in vivo as single-component gene transfer vectors. ppTG1 and ppTG20 bind to nucleic acids and destabilize liposomes consisting of 1-palmitoyl-2-oleoylphosphatidylcholine (POPC) and cholesterol (3:1 mol/mol) at pH 5 and pH 7. Complexes of plasmid DNA and ppTG1 gave rise to efficient transfection in a variety of human and murine cell lines at low charge ratios ([+/-] between 1 and 2). In cell culture experiments, such vectors were superior to the membrane-destabilizing peptide KALA. In comparison with cationic lipid-, dendrimer-, and polymer-based transfection agents like Superfect, polyethylenimine (PEI), and Lipofectin, ppTG1 vectors showed good transfection efficiencies, especially at low DNA doses. Moreover, we demonstrated for the first time successful gene transfer in living animals with a single-component peptide vector. In the mouse, intravenous injection of a luciferase expression plasmid complexed with ppTG1 or ppTG20 led to significant gene expression in the lung 24 hours after injection. Structure-function studies with ppTG1, ppTG20, and sequence variants suggest that the high gene transfer activity of these peptides is correlated with their propensity to exist in alpha-helical conformation, which seems to be strongly influenced by the nature of the hydrophobic amino acids.

MM is a B-cell malignancy mainly characterized by monoclonal expansion of plasma cells in the BM, presence of paraprotein in serum and occurrence of osteolytic bone lesions. MMPs are a family of proteolytic enzymes that can contribute to cancer growth, invasion, angiogenesis, bone degradation and other processes important in the pathogenesis of MM. We investigated MMP-9 production in the 5T33MM murine model. Expression of MMP-9 protein in supernatant and cell extracts was analyzed by gelatin zymography. The in vitro, stroma-independent variant 5T33MMvt showed no protein expression of MMP-9 in contrast to in vivo growing MM cells, 5T33MMvv. However, when 5T33MMvt cells were injected into naive mice and isolated after tumor take (5T33MMvt-vv), they secreted a significant amount of MMP-9. These results were confirmed by specific staining of cytospins with an anti-MMP-9 antibody. The MMP-9 production by 5T33MMvt-vv cells disappeared when the cells were recultured in vitro. These data demonstrated that upregulation of MMP-9 occurs in vivo and that this process is dependent on the microenvironment. Cocultures of 5T33MMvt cells with STR10 BMECs induced MMP-9 in MM cells, as determined by both gelatin zymography and flow-cytometric analysis. In conclusion, our results demonstrate that MMP-9 production by MM cells is upregulated in vivo by the interaction of MM cells with BMECs. [less ▲]

Répertoire de 48 termes méprisants ou insultants utilisés par des philosophes antagonistes pour qualifier leurs adversaires et leurs doctrines. On notera d’ailleurs qu’il existe également des auteurs qui écrivent leurs œuvres en igorant toute polémique et toute attaque personnelle. Ainsi Maņḍanamiśra (vers 700.). D’autres, au nombre de 26 ci-après, se laissent aller à la critique personnelle (sans d’ailleurs citer l’opposant par son nom) et à l’invective. L’article énumère les mots ainsi utilisés dans l’ordre alphabétique du sanskrit et y joint un bref commentaire. Voici quelques exemples. Le bouddhiste Dignāga décrit ses adversaires comme de « mauvais logiciens » (kutarka) imbus de leurs vues erronées (abhimāna). Tout en utilisant le terme de « votre honneur » (āyuṣmant , tatrabhavant) , on traitera l’opposant de « fou » (unmatta, jaḍa, mūrkha, pramatta, manda, mūḍha), de « gosse » (bāla), d’ « animal » (paśu). A noter l’expression devānāṃpriya « chéri des dieux » synonyme de « fou », qui équivaut mutatis mutandis à « imbécile heureux ». On peut ajouter des expressions d’indignation et de mépris comme « ah, la grande folie ! propos totalement stupide, propos d’aveugle, divagation, énormité ». [less ▲]

The phenomenon of ozone tolerance is described, but the underlying mechanisms remain unknown. We tested whether adaptation to multiday ozone exposure was related to an upregulated pulmonary antioxidant defence. Six calves were exposed to 0.75 ppm ozone, 12 h day(-1) for seven consecutive days. Pulmonary function tests and bronchoalveolar lavage (BAL) were performed before, after the first (D1), third (D3) and seventh (D7) exposure. Differential cell count, total proteins, 8-epi-PGF2alpha, glutathione and uric acid were determined in BAL. Dynamic lung compliance and arterial oxygen tension were significantly decreased and lung oedema impaired pulmonary function on D1. By repeating ozone exposures, progressive functional adaptation occurred. Ozone induced a significant increase of BAL neutrophil percentage on D1. On D3 and D7, neutrophil percentage was progressively decreased, but remained significantly elevated. BAL total proteins were significantly increased on D1 and decreased progressively until D7. 8-Epi-PGF2alpha was significantly increased on D1 and was returned to baseline on D3 and D7, whilst glutathione significantly increased on D3 and returned to baseline on D7. Uric acid was increased ten-fold on D1. On D3, uric acid was increased six-fold and was persistently elevated at D7. This study suggests that ozone adaptation of functional and inflammatory variables is accompanied with sustained BAL uric acid elevation. [less ▲]

Since the Earth Summit in Rio, declining biodiversity has become a subject of general concern for many countries. To counter these negative trends, government nature policies in Europe at least are now thought out primarily in terms of networks. They concern new areas outside nature reserves, new players and new management strategies. Consequently, these policies should themselves become the subject of new public debate. Our study concerns the analysis of the forms used to collect the data required to set up the European Union's Natura 2000 network and maps drawn as part of the Council of Europe's Pan-European Ecological Network strategy. The aim of this article, which takes the perspective developed by the sociology of science, will be to show how the forms and maps used in these new nature policies produce knowledge that precedes policy discussions to search for the best possible socio-political compromises. In other words, the knowledge that is collected in and by means of these documents, forms and maps offers a cognitive way of framing the subsequent public debates. [less ▲]

Purpose: We present results obtained by computer modeling of the thalamic network and differential gene expression analysis in a rat strain with absence epilepsy, the genetic absence epilepsy rat from Strasbourg (GAERS). Methods: (a) Computer modeling used equations from the Hodgking-Huxley model with a circuit of 13 reticular thalamic (nRt) and 39 thalamocortical (TC) neurons; (b) gene-expression analysis using differential mRNA display (DD), in situ hybridization, Northern blotting, and competitive reverse transcriptase-polymerase chain reaction (RT-PCR). Results: (a) Computer modeling showed an increased network synchrony in the thalamic circuit as the value of conductance of low-voltage activated calcium channel (LVACC) is increased. (b) Using differential mRNA display, a 40% upregulation of the H-ferritin mRNA in the hippocampus was demonstrated. Looking for some candidate genes of the VACC family, no difference was found in the alpha1G mRNA expression between GAERS and control animals, whereas a decreased expression of the alpha1E subunit was observed in the cerebellum and the brainstem of the GAERS. This phenomenon was not observed in young animals when the epileptic phenotype is not expressed. Conclusions: The use of computer modeling appeared to be an efficient way to evaluate the impacts of electrophysiologic findings in vivo from single cells on an entire circuit. No clear single gene defect was revealed so far in GAERS. More information could arise from linkage analysis. However, some brain structures like hippocampus or cerebellum classically not known to be involved in the production of absence spike-and-wave discharges could in fact participate in the development of this phenotype.

The paper discusses the ability of recognition models to classify malodours in the environment 3 years after their calibration, with the same sources releasing odours. Two methodologies applicable either in the lab or in the field are used. The effect of the long term drift of the sensors is highlighted on the results of principal component analysis (PCA) and of discriminant function analysis (DFA). The paper examines also the applicability of some drift counteraction methods proposed in the literature. Handled with some care, a correction based on the drift direction in the principal components subspace should be applicable to the classification of real odorous sources in the field. [less ▲]

The density functional theory (DFT) computation of electronic structure, total energy and other properties of materials, is a field in constant progress. In order to stay at the forefront of knowledge, a DFT software project can benefit enormously from widespread collaboration, if handled properly. Also, modern software engineering concepts can considerably ease its development. The ABINIT project relies upon these ideas: freedom of sources, reliability, portability, and self-documentation are emphasised, in the development of a sophisticated plane-wave pseudopotential code. We describe ABINITv3.0, distributed under the GNU General Public License. The list of ABINITv3.0 capabilities is presented, as well as the different software techniques that have been used until now: PERL scripts and CPP directives treat a unique set of FORTRAN90 source files to generate sequential (or parallel) object code for many different platforms; more than 200 automated tests secure existing capabilities; strict coding rules are followed; the documentation is extensive, including online help files, tutorials, and HTML-formatted sources.

Airborne atmospheric and in-situ soil gas analyses demonstrate that distal gas leaks are non-existent at Piton de la Fournaise (PF) despite frequent eruptions. Airborne traverses made at a constant altitude indicated that no detectable large-scale CO2 degassing occurs from the volcano. In-situ soil gas traverses (CO2, He-4, Rn-222) across the active riftzones, the summit crater and the caldera rims, show both a lack of positive anomalies and evidence of strong depleted concentrations for He and CO2 with respect to air. Depletions in soil He is explained by intense rain water infiltration. A more unexpected result lies in the very low CO2 concentrations (down to 92 ppm) in bare soils in the summit region. Such a depletion was not previously reported and is attributed to considerable basalt weathering operating as the result of huge runoff. A model has enabled both the runoff and the CO2 consumption occurring within the basaltic layers to be calculated. Data obtained are consistent with values expected from large-scale erosion models and with the local calculated diffusive flux of CO2 in soils. The huge runoff, together with the basaltic lithology of the volcano, are found to be the main factor controlling the soil gas signatures at PF. (C) 2002 Elsevier Science B.V. All rights reserved.

A hydride generation flame atomic absorption spectrometric method was developed and optimized to quantitate arsenic (As) in foods. A wet digestion of the samples with HNO3 + H2O2 was performed and excess oxidants were eliminated by addition of hydrochloric acid and urea. As5+ in As3+ was then reduced by potassium iodide. The As3+ solution was analyzed by generation of arsine with sodium tetrahydroborate. As determination ranged from 2.5 to 20 microg/L, with a determination coefficient of 0.997. The limits of detection (LOD) and quantitation (LOQ) were 0.6 and 2.1 microg/L, respectively. The method was validated and good results were obtained for recovery, precision, accuracy, LOD, and LOQ. This method is now used to analyze foods from Rwanda. [less ▲]

BACKGROUND: A number of challenge studies have reported abnormalities of serotonergic function in borderline personality disorder (BPD). There are, however, problems with the pharmacological probes used in these studies since fenfluramine and m-CPP are not only serotonergic agents but also induce release of catecholamines, particularly dopamine. Therefore, we tested whether subjects with BPD showed a blunted prolactin (PRL) response to flesinoxan, a highly potent and selective 5-HT1A agonist. METHODS: Flesinoxan challenge test was carried out in 20 BPD in-patients and 20 healthy controls matched for gender but not for age. Since 16 BPD in-patients exhibited major depressive co-morbidity, a group of 20 depressed in-patients matched for gender but not for age was also included. RESULTS: BPD in-patients exhibited blunted PRL responses as compared to controls, whereas depressed in-patients did not differ from controls. Moreover, PRL responses were lower among BPD in-patients than among depressed in-patients. Among the BPD in-patients, PRL responses to flesinoxan were lower in patients with past history of suicide attempts (N = 8) than in those with a negative history. CONCLUSIONS: The results show major involvement of serotonergic function in BPD and are consistent with previous studies linking lower serotonergic activity with impulsivity. More particularly, our data suggest that BPD is characterized by lower 5-HT1A receptor sensitivity. Moreover, the data support the involvement of 5-HT1A activity in suicidal behaviour. However, this conclusion is limited because other hormonal responses such as ACTH and cortisol were not assessed, and because BPD was assessed by a self-report questionnaire and not a structured clinical interview.

Thallium L-III-edge x-ray absorption and iron-57 and tin-119 Mossbauer spectral measurements have been carried out to probe the electronic structure of the three sites in the filled skutterudite TlxCo4-yFeySb12 and TlxCo4Sb12-zSnz compounds with a range of x, y, and z values. The thallium L-III-edge x-ray absorption spectra are independent of x, y, and z and are well reproduced by full multiple scattering calculations with a cluster with a radius of 8.5 Angstrom centered on thallium. The iron-57 Mossbauer spectra consist of two doublets and the major component is assigned to iron on the cobalt sublattice in view of its hyperfine parameters. The origin of the minor component is uncertain and is tentatively assigned to either iron with thallium vacancies as next nearest neighbors or to iron in the voids. The tin-119 Mossbauer spectral hyperfine parameters clearly indicate that tin substitutes for antimony in the skutterudite structure. Further, the tin electronic configuration is very similar to that of antimony and is insensitive to the thallium content. (C) 2002 American Institute of Physics. [less ▲]

This research has mostly concerned itself with relations between psychopathology and transsexualism. Practically non-existent are studies investigating the psychological conditions that permit, shape or induce sex change requests in individuals. Transsexuals request the removal of their genitals through mutilation surgery, which can be seen as subjects literally crying out to be castrated. This request is all the more surprising given that castration, in psychoanalytic terms, is considered to be the most severe punishment that an individual (woman or man) can be threatened with. Therefore, we asked ourselves which psychic conditions could motivate such as request. Based on any earlier study where answers (some explicit, others symbolic) given by sex-change applicants tested on the Rorschach were analysed, results seemed to suggest a counter-phobic attitude underlying sex-reassignment requests (28). According to these hypotheses, the fear of castration (banal as such) can only be overcome through the active search for castration itself. In opting for castration, the transsexual puts an end to the states of anxious waiting that are dominated by feelings of the incertitude and unpredictability of an eventual castration. Once obtained, the threat it constituted disappears, and with it so does the fear. Thus, by taking this active and voluntary step, the subject is no longer exposed to an imminent danger in a passive manner. This in itself creates a great feeling of relief, if not of actual pleasure in the subject (28). In this article, we postulated in a purely speculative manner, the existence of one or several modalities in the transsexual dynamics. Nevertheless, one can ask oneself about the possibility of a request based on a desire rather than on a defense, or even on the existence of a defensive process diametrically opposed to the counter-phobic attitude and which, instead of actively provoking the dreaded reality, would privilege its avoidance and the search of passivity. This latter hypothesis has the advantage of being rather easy to explore with the Rorschach because, according to Exner, the predominance of passive compared to active human movement responses (which he terms the Snow White Syndrome) indicates the propensity to escape into passive fantasies and the tendency to avoid the initiative for behaviour or decision-making, if other people can do it in the subject's place (12). Our results largely confirmed the hypothesis of the existence of an opposite mechanism, as a third of subjects (n = 26) presented Snow White Syndrome. According to Exner, these transsexuals are typically characterized by hiding into a world of make believe, avoiding all responsibility, as well as any decision-making. This passivity in our Snow White Syndrome group was all the more remarkable in that, on the whole, it infiltrated into all the movement responses and seemed to define a rigid style of thinking and mental elaboration, in addition to a suggestive content of passivity. However, this condition cannot be associated with a general lack of dynamism or energy. In fact, the treatment of information, which provides data concerning the motivation to treat a stimulus field of the stimulus--whether this concerns the capture (L) of the stimulus or the elaboration (DQ+) of the response--displayed a sufficient amount of motivation. Furthermore, internal resources (EA) were considerable and were brought into play whenever it was necessary to adopt a behaviour or make a decision. Furthermore, based on these Rorschach findings, we note that in transsexuals with Snow White Syndrome, there is a stereotyped tendency to shy away from difficulties by seeking refuge in realistic representations (but that lack in variety), which could be materialized by actions, but where the initiative is delegated to others. These transsexuals appear to shy away from the difficulties of life by seeking refuge into a world of fantasy, which they fill with the representations borrowed from reality (rather than fantasy) and consequently that are liable to be transposed, if necessary, back into reality. Therefore, one can better understand why they shun away from the deceiving reality that their physical sex represents, into the satisfying dream where they possess the genitals of the opposite sex, that is, a perfectly real organ, no longer the result of the subject's fantasy world.

ENDIT ("European Nicotinamide Diabetes Intervention Trial") is a large placebo-controlled randomised clinical trial that aimed at studying the efficacy of nicotinamide in the prevention of type 1 diabetes mellitus among first-degree relatives of type 1 diabetic patients with positive islet cell antibodies (ICA). The results presented at the last congress of the European Association for the Study of Diabetes (EASD) in Budapest do not evidence any significant difference in the risk of developing overt diabetes mellitus in the patients treated with nicotinamide (n = 274) as compared to those receiving placebo (n = 275) after 5 years of follow-up. Despite these negative results, positive lessons could be drawn from ENDIT: 1) the feasibility of a large long-standing multicentre European trial in a difficult research area; 2) the importance of large randomised controlled clinical trials to bring the evidence requested by "Evidence-Based Medicine"; 3) the predictive value of various risk markers to progress toward type 1 diabetes in first-degree relatives, especially the number of positive auto-antibodies; and 4) the urgent need to continue intensive research in this important field of preventive medicine.

Data on the distribution of the partial pressure of CO2 (pCO2) were obtained during six cruises off the Galician coast, a region characterized by a seasonal upwelling. The values of pCO2 over the continental shelf are highly variable and range between 265 and 415 matm during the upwelling season and between 315 and 345 matm during the downwelling season. Both the continental shelf and off-shelf waters behave as significant net sinks of atmospheric CO2. The computation of the air-sea fluxes of CO2 over the continental shelf yields a net influx in the range of 2.3 (±0.6) to 4.7 (±1.0) mmol C m 2 d 1 during the upwelling season and 3.5 (±0.8) to 7.0 (±1.5) mmol C m 2 d 1 on an annual basis. During the upwelling season and on an annual basis, although the observed air-sea gradients of CO2 over the continental shelf are significantly stronger than those in off-shelf waters, the computed air-sea CO2 fluxes are not significantly different because of the important incertitude introduced in the calculations by the estimated error on wind speed measurements. The presence of upwelling filaments increases the influx of atmospheric CO2 in the off-shelf waters. During summer, important short-term variations of pCO2 are observed that are related to both upwelling and temperature variations. During winter the cooling of water causes important undersaturation of CO2 related to the effect of temperature on the dissolved inorganic carbon equilibrium constants. [less ▲]

Bacteria can have population structures ranging from the fully sexual to the highly clonal. Despite numerous studies, the population structure of Pseudomonas aeruginosa is still somewhat contentious. We used a polyphasic approach in order to shed new light on this issue. A data set consisting of three outer membrane (lipo)protein gene sequences (oprI, oprL and oprD), a DNA-based fingerprint (amplified fragment length polymorphism), serotype and pyoverdine type of 73 P. aeruginosa clinical and environmental isolates, collected across the world, was analysed using biological data analysis software. We observed a clear mosaicism in the results, non-congruence between results of different typing methods and a microscale mosaic structure in the oprD gene. Hence, in this network, we also observed some clonal complexes characterized by an almost identical data set. The most recent clones exhibited serotypes O1, 6, 11 and 12. No obvious correlation was observed between these dominant clones and habitat or, with the exception of some recent clones, geographical origin. Our results are consistent with, and even clarify, some seemingly contradictory results in earlier epidemiological studies. Therefore, we suggest an epidemic population structure for P. aeruginosa, comparable with that of Neisseria meningitidis, a superficially clonal structure with frequent recombinations, in which occasionally highly successful epidemic clones arise.

PURPOSE: We define guidelines for the exploration and treatment of adult mullerian duct cysts. MATERIALS AND METHODS: From January 1988 through September 1999 a diagnosis of enlarged prostatic utricle was made in 65 adults based on transrectal ultrasound findings. Echographic criteria to define simple versus complicated cysts were detailed. We reviewed the clinical presentation, diagnostic modalities, indications for invasive procedures and postoperative outcome. RESULTS: The usual clinical presentations were hematospermia in 40% of cases, other ejaculatory disturbances in 20%, recurrent testicular or pelviperineal pain in 33%, lower urinary tract irritation symptoms in 25%, lower urinary tract infection in 18.5%, male infertility in 12% and incidental finding in 18.5%. Cyst dimensions did not influence the indication for invasive procedures, which were performed in only 27 of the 65 patients (41.5%) to treat disabling symptoms in 28% and obstructive infertility in 5%, and investigate complicated cysts on transrectal ultrasound in 6%. These procedures included transperineal or transrectal puncture in 9 patients, simple endoscopic section of the utricle meatus in 12 and large marsupialisation in 6. Complete and sustained cure was noted in half of the patients treated with cyst puncture only, although echographic relapse was the rule. Endoscopic procedures definitely improved or cured 82% of the patients at a mean followup of 51 months, during which neither early nor late complications were noted. CONCLUSIONS: Since almost 60% of adults diagnosed with a mullerian duct cyst did not experience any cyst related symptoms or ejaculatory-fertility impairment, we recommend that investigation and/or treatment should only be done in symptomatic or infertile patients.

Besides genetic predisposition, obesity is the most important risk factor for the development of type 2 diabetes mellitus. Even modest weight reduction can improve blood glucose control in overweight subjects. After failure of lifestyle modifications, antiobesity drugs such as orlistat, a potent and selective inhibitor of gastric and pancreatic lipases that reduces lipid intestinal absorption, or sibutramine, a noradrenaline and 5-hydroxytryptamine reuptake inhibitor that regulates food intake, may be considered to favour weight loss and/or weight maintenance. Several placebo-controlled studies have recently demonstrated that both drugs are able to promote weight loss in obese type 2 diabetic patients treated with diet alone, sulphonylureas, metformin or insulin. The greater weight reduction as compared to placebo was associated with a significant reduction of glycated haemoglobin levels and/or of the doses of classical antihyperglycaemic agents, especially in good responders who lost at least 10% of initial body weight. In addition, vascular risk factors associated to insulin resistance were also reduced after weight loss. These antiobesity agents may also contribute to delay or prevent the progression from impaired glucose tolerance to overt type 2 diabetes in at risk obese individuals ("Xenical in the prevention of diabetes in obese subjects" trial). Large long-term prospective studies, such as the "Sibutramine cardiovascular and diabetes outcome study" should better determine the place of pharmacological anti-obesity strategy in the overall management of obese patients with impaired glucose tolerance or type 2 diabetes.

Development of a soft-tissue sarcoma is an infrequent but well-known long-term complication of radiotherapy. Malignant fibrous histiocytomas, extraskeletal osteosarcomas, fibrosarcomas, malignant peripheral nerve sheath tumors, and angiosarcomas are most frequently encountered. Radiationassociated synovial sarcomas are exceptional. We report the clinicopathologic, immunohistochemical, and molecular features of two radiationassociated synovial sarcomas. One tumor developed in a 42-year-old female 17 years after external irradiation was given for breast carcinoma; the other occurred in a 34-year-old female who was irradiated at the age of 7 years for a nonneoplastic condition of the left hand. Both lesions showed morphologic features of monophasic spindle cell synovial sarcoma, were immunoreactive for cytokeratins, epithelial membrane antigen, CD99, CD117 (c-kit), and bcl-2 and bore the t(X;18) (SYT-SSX1) translocation. We conclude that synovial sarcoma has to be added to the list of radiation-associated soft-tissue sarcomas. Mod Pathol 2002;15(9):998–1004 [less ▲]

Some odorant lactones are naturally present in fruits or in fermented products; they can also be used as food additives and can be produced by microorganisms at the industrial scale by biotechnological processes. Gamma-decalactone was previously shown to have antimicrobial properties. We determined by infrared spectroscopy measurements that this compound rapidly diffused into model phospholipid bilayers (within 2 min), modifying the general physical state of a dimyristoyl-L-alpha-phosphatidylcholine (DMPC) film. In vivo, the lactone strongly increased membrane fluidity in the model yeast Yarrowia lipolytica, as evaluated by fluorescence anisotropy measurements. This effect was more important than that of benzyl alcohol, which is known as a fluidizing agent in living cells, and may explain the toxic action of gamma-decalactone in microorganisms. [less ▲]

We obtained a stable transformed fish (EPC) cell line containing a reporter gene under the control of the tilapia HSP70 promoter. Expression of the reporter gene, coding for a green fluorescent protein (GFP)-luciferase fusion protein, was assessed by measuring the luciferase enzymatic activity by luminometry and the GFP expression by fluorescence microscopy and flow cytometry. The clone was characterized for its capacity to respond to heat shock treatment. The results show high induction after 1 h at 37 degrees C of treatment, up to 500-fold. In addition, its convenience to detect a large range of cellular stressors was evaluated. We observed high induction when Cd2+, Zn2+, Hg2+ or Cu2+ was added, but not Pb2+. In addition, activation of the reporter gene was observed in the presence of other compounds such as acetyl chloride, tetrachlorophenol, chloroacetamide and sodium arsenite. In conclusion, this cell line can be used as a rapid, cheap and easy biological test to determine cellular stress induced by environmental pollutants, alone or in conjunction with other, more specific assays.

New 1,3-diarylimidazol(in)ium chlorides bearing phenyl, 1-naphthyl, 4-biphenyl, 2-tolyl, 2,6-dimethylphenyl, and 3,5-dimethylphenyl substituents were synthesized. They were combined with [RuCl2 (p-cymene)](2) and potassium tert-butoxide or sodium hydride to generate the corresponding ruthenium-N-heterocyclic carbene complexes in situ. Catalyst precursors derived from imidazol(in)ium salts bearing the 2,4,6-trimethylphenyl (mesityl) and the 2,6-diisopropylphenyl groups were also prepared. The catalytic activity of all these species in the photoinduced ring-opening metathesis polymerization of cyclooctene was investigated. The C4-C5 double bond in the imidazole ring of the N-heterocyclic carbene ligands was not crucial to achieve high catalytic efficiencies. The presence or the absence of alkyl groups on the ortho positions of the phenyl rings had a more pronounced influence. Blocking all the ortho positions was a requisite for obtaining efficient catalysts. Failure to do so probably results in the ortho-metallation of the carbene ligand, thereby altering the coordination sphere of the ruthenium active centers. [less ▲]

BACKGROUND: It is now well established that after conventional allogeneic hematopoietic stem-cell transplantation (HSCT), erythropoietic recovery is impaired because erythropoietin (Epo) production remains inadequate for prolonged periods of time. However, erythropoietic reconstitution after nonmyeloablative SCT (NMSCT) has never been characterized. METHODS: Twelve patients received a nonmyeloablative conditioning regimen consisting of 2 Gy total body irradiation (TBI) alone (n=6), 2 Gy TBI and fludarabine (n=3), or cyclophosphamide and fludarabine (n=3), followed by transplantation of allogeneic peripheral blood stem cells. Graft-versus-host-disease (GvHD) prophylaxis was carried out with mycophenolate mofetil (from day -1 to day 28) plus cyclosporine (from day -1 to day 120 or longer in case of chronic GvHD). Erythropoiesis was quantitated by soluble transferrin receptor (sTfR) levels, and the adequacy of Epo production was evaluated by the observed-to-predicted Epo ratio (O/P Epo). RESULTS: Mean sTfR levels decreased following the conditioning regimen but remained well within the normal range throughout the posttransplant period. The O/P Epo ratio presented an initial surge quite similar to that observed after conventional conditioning. Thereafter, the O/P Epo ratio normalized rapidly, and Epo levels remained adequate during the whole observation period. CONCLUSION: Contrarily to what is observed after myeloablative transplant, Epo levels remained adequate after NMSCT, resulting in normal erythropoiesis. These results suggest that the administration of erythropoietin therapy (rHuEpo) could be less effective after NMSCT than after conventional allogeneic transplant. [less ▲]

BACKGROUND: The in vivo interdependence between the phenotypic characteristics of dermal cells and the strain imposed on the tissue has not been studied thoroughly in humans. In particular the mechanical force modulation of Factor XIII a expression in dermal dendrocytes (DD) remains unknown. MATERIALS AND METHODS: The present study compares the numerical density of Factor XIII a-positive DD and the in vivo shear wave velocity in the skin. The investigation was performed in 20 men of normal weight and 20 obese men before and after entering a slimming process. RESULTS: Excess cutaneous fat places the skin under increased intrinsic tension. The resonance running time measurement (RRTM) and the DD density were significantly reduced in overweight individuals. After a short-term but intense slimming process, the same individuals showed a trend to normalization of these two parameters without, however, reaching significance. Pooling all data yielded a significant logarithmic correlation between RRTM values and densities in Factor XIII a-positive DD. CONCLUSION: Factor XIII a expression in human DD may be partially regulated by the intrinsic resting tensions in the skin. [less ▲]

The aim of this study was to evaluate the effect of body positioning immediately after delivery on respiratory and metabolic adaptation to extra-uterine life in newborn calves. One hundred and one Belgian White and Blue calves were delivered at term by an elective caesarean section and were assigned into three categories according to the body position imposed immediately after umbilical cord rupture: 71 calves were placed in lateral recumbency; 16 calves were placed in sternal recumbency and 14 calves were suspended by the hind legs for less than 90 seconds (75 +/- 5 s). Following this initial body position, the calves were allowed to move without restraint. They were examined at birth, 5, 15, 30, 45 and 60 minutes, and 2, 3, 6, 12 and 24 hours after birth by the following measurements: physical examination, heart rate, arterial blood gas analysis, pulmonary function tests using the esophageal balloon catheter technique, arterial and venous blood acid-base balance analysis, rectal temperature, jugular venous blood sampling for the determination of blood glucose, plasma lactate and serum cortisol concentrations, haematologic variables and passive immune transfer variables. Body positioning immediately after delivery clearly influenced respiratory and metabolic adaptation to extra-uterine life in term calves delivered by an elective caesarean section. Systematic sternal recumbency and suspension by the hind legs for less than 90 seconds immediately after umbilical cord rupture had a positive functional impact on postnatal pulmonary mechanics and gas exchange and on postnatal correction of mixed acidosis present at birth, contributing in turn to an enhanced passive immune transfer. These two body positions should be encouraged to improve adaptation at birth in healthy term calves delivered by an elective caesarean section. Evaluation of possible side-effects is required before application in severely asphyxiated calves. [less ▲]

The selectivity of [F-18]MPPF (fluorine-18-labeled 4-(2'-methoxyphenyl)-1-[2'-(N-2"-pirydynyl)-p-fluorobenzamido]ethylpiperazine) for serotonergic 5-hydroxytryptamine(1A) (5-HT1A) receptors has been established in animals and humans. The authors quantified the parameters of ligand-receptor exchanges using a double-injection protocol. After injection of a tracer and a coinjection dose of [F-18]MPPF, dynamic positron emission tomography (PET) data Were acquired during a 160-minute session in five healthy males. These PET and magnetic resonance imaging data were coregistered for anatomical identification. A three-compartment model was used to determine six parameters: F-v (vascular fraction). K-1, k(2) (plasma/free compartment exchange rate). k(off). k(on)/V-r (association and dissociation rate), B-max (receptor concentration), and to deduce K-d (apparent equilibrium dissociation rate). The model was fitted with regional PET kinetics and arterial input function corrected for metabolites. Analytical distribution volume and binding potential Were compared With indices generated by Logan-Patlak graphical analysis. The 5HT(1A) specificity for MPPF was evidenced. A B-max of 2.9 pmol/mL and a K-d of 2.8 nmol/L were found in hippocampal regions, K-d and distribution volume in the free compartment were regionally stable. and the Logan binding potential was linearly correlated to B-max. This study confirms the value of MPPF in the investigation of normal and pathologic systems involving the limbic network and 5-HT1A receptors. Standard values can be used for the simulation of simplified protocols. [less ▲]

Collaborative work was financed by the EU to develop and assess new diagnostic tools that can differentiate between bovine brucellosis and bovine infections due to Yersinia enterocolitica O:9 either in conjunction with, or as an alternative to, the classical serological, bacteriological or allergic skin tests. Sixteen heifers were experimentally infected with Brucella abortus biovar 1 (five heifers), Brucella suis biovar 2 (two heifers), Y. enterocolitica O:9 (six heifers) and Y. enterocolitica O:3 (three heifers). Four heifers, naturally infected with Y. enterocolitica O:9 that presented aspecific brucellosis serological reactions were also included in the experiment. A self-limited infection was induced in cattle by B. suis biovar 2. All the brucellosis serological tests used, i.e. the slow agglutination test (SAW), the Rose Bengal test (RB), the complement fixation test (CFT), indirect and competitive ELISA's, lacked specificity when used to analyze sera from Y. enterocolitica O:9 infected animals. A Yersinia outer membrane proteins (YOPs)-ELISA was also used and although the test is able to detect a Yersinia group infection, it provided no evidence of whether or not there is a possible brucellosis infection when dual infections are present. The brucellergen IFN-gamma test showed a lack of specificity also. The only test that was proven to be specific is the brucellergen skin test. All brucellosis serological tests, except the indirect ELISA, were limited in their ability to detect B. abortus persistently infected animals. Based on these experimental studies, a strategy was implemented as part of the year 2001 Belgian Brucellosis Eradication Program to substantiate the eradication of bovine brucellosis. Epidemiological inquiries have identified risk factors associated with aspecific serological reactions, possible transmission and infection of cattle by B. suis biovar 2 from infected wild boars; and both legal and administrative measures taken by the veterinary services. No cases of bovine brucellosis have been confirmed in Belgium since March 2000. [less ▲]

The effect of hydrophobic chain length on surface properties of enzymatically prepared n-alkyl esters of glucuronic acid are examined. Dynamic parameters from Hua and Rosen's mathematical model and equilibrium surface tension are presented for esters with octyl, decyl, dodecyl, and tetradecyl alkyl segments. Increasing the alkyl chain length has a significant influence on the surface activity. Decyl and dodecyl glucuronate exhibit an interesting adsorption speed associated with foaming capacity. Octyl glucuronate exhibits a micellar organization as its bulk concentration is over 10.68 mM. (C) 2002 Elsevier Science (USA). [less ▲]

We herein report the results of a whole genome scan performed in a Pietrain x Large White intercross counting 525 offspring to map QTL influencing economically important growth and carcass traits. We report experiment-wide significant lod scores (> 4.6) for meatiness and fat deposition on chromosome SSC2, and for average daily gain and carcass length on chromosome SSC7. Additional suggestive lod scores (> 3.3) for fat deposition are reported on chromosomes SSC1, SSC7 and SSC13. A significant dominance deviation was found for the QTL on SSC1, while the hypothesis of an additive QTL could not be rejected for the QTL on SSC7 and SSC13. No evidence for imprinted QTL could be found for QTL other than the one previously reported on SSC2. [less ▲]

We determined the frequency of strength disorders in 26 athletes with a history of hamstring muscle injury and recurrent strains and discomfort. We also assessed the effectiveness of rehabilitation to correct muscle performance. After concentric and eccentric isokinetic assessment, 18 athletes were found to have strength deficits, as determined by statistically selected cutoffs of peak torque, bilateral differences, and the flexors/quadriceps ratio. The discriminating character of the eccentric trial was demonstrated, combining a preferential eccentric peak torque deficit and a significant reduction of the mixed eccentric flexors/concentric quadriceps ratio. The athletes with muscle imbalances followed a rehabilitation program individually adapted from their strength profile. Treatment length was from 10 to 30 sessions and resulted in isokinetic parameter normalization in 17 of 18 subjects. Isokinetically corrected subjects were observed for 12 months after return to athletics. None sustained a clinically diagnosed hamstring muscle reinjury. Subjective intensity of pain and discomfort were significantly reduced, and they all returned to their prior level of competition. These results demonstrate that persistent muscle strength abnormalities may give rise to recurrent hamstring injuries and discomfort. An individualized rehabilitation program emphasizing eccentric training based on specific deficits contributes to a decrease in symptoms on return to sports. [less ▲]

Bovine leukemia virus (BLV) is a complex retrovirus that belongs to the Deltaretrovirus genus, which also includes Human T-cell leukemia virus type 1 (HTLV-1). Both viruses contain an X region coding for at least four proteins: Tax and Rex, which are involved in transcriptional and posttranscriptional regulation, respectively, and the accessory proteins R3 and G4 (for BLV) and p12(I), p13(II), and p30(II) (for HTLV-1). The present study was aimed at characterizing the subcellular localization of BLV R3 and G4. The results of immunofluorescence experiments on transfected HeLa Tat cells demonstrated that R3 is located in the nucleus and in cellular membranes, as previously reported for HTLV-1 p12(1). In contrast, G4, like p13(II), is localized both in the nucleus and in mitochondria. In addition, we have shown that G4 harbors a mitochondrial targeting signal consisting of a hydrophobic region and an amphipathic alpha-helix. Thus, despite a lack of significant primary sequence homology, R3 and p12(1) and G4 and p13(II) exhibit similar targeting properties, suggesting possible overlap in their functional properties.

The purpose of this study was to describe the computed tomographic (CT) features of nasal aspergillosis in dogs. Initial (n = 35) and follow-up (n = 12) CT images were available from 35 dogs. The most commonly encountered CT findings were (1) moderate to severe cavitary destruction of the turbinates with presence of a variable amount of abnormal soft tissue in the nasal passages, (2) non-specific thickening of the mucosa adjacent to the inner surface of bones of the frontal sinus, maxillary recess and nasal cavity and, (3) thickened reactive bone. The findings were consistent with a disease initially affecting one nasal cavity then progressing into the ipsilateral frontal sinus, the contralateral nasal cavity and the contralateral frontal sinus. Two dogs with associated nasal foreign body had a more localized invasion of the nasal cavity. Attenuation values and contrast enhancement were not specific. With follow-up examinations, a reduction in the amount of abnormal soft tissue was observed in all dogs except one, but this reduction could not be quantified. [less ▲]

The prospective placebo-controlled LIPS study ("Lescol Intervention Prevention Study") demonstrated a significant cardiovascular protection by fluvastatin in patients with coronary artery disease (stable or unstable angina, silent ischemia), without major hypercholesterolaemia (135-270 mg/dl) following successful completion of their first percutaneous coronary intervention. When compared to the placebo group (n = 833), the fluvastatin group (n = 844) showed a relative risk reduction by 22% (relative risk: 0.78; 95% confidence interval: 0.64-0.95; p = 0.01) of major adverse cardiac events after a median time of follow-up of 3.9 years. This effect is observed independently of baseline total cholesterol, of the presence of diabetes mellitus or the existence of multivessel disease. These results suggest that fluvastatin may favorably influence the restenosis process after percutaneous coronary intervention, even in the absence of severe hypercholesterolaemia. [less ▲]

BACKGROUND/AIMS: Beyond subjective assessments, the effect of skin tensors is difficult to assess. The present 2-phase randomized double-blind split face study was designed to compare the effect of a gel containing 3% 2-dimethylaminoethanol (deanol, DMAE) with the same formulation without DMAE. METHODS: In a first pilot study, sensorial assessments and measures of the skin distension under suction were performed in eight volunteers. In a second study conducted in 30 volunteers, shear wave propagation was measured. RESULTS: Large interindividual variations precluded any significant finding in the first study. The DMAE formulation showed, however, a significant effect characterized by increased shear wave velocity in the direction where the mechanical anisotropy of skin showed looseness. CONCLUSION: The DMAE formulation under investigation increased skin firmness. [less ▲]
