The propagation of light in linearly birefringent and optically active media, such as Bi12SiO20 crystals (BSO), has been widely studied by several workers. Various measurement methods of the electro-optic coefficient r41 have been described. One family of those methods consisting in measurement of the light polarization ellipticity after travelling through the crystal has been analysed. Due to the high reflectivity of such crystals, we show that the effect of the secondary reflections can not be neglected. We present the theoretical description and analysis of this effect for one of these methods and we propose a corrective algorithm. [less ▲]

Because a wide variety of conditions can be diagnosed hysteroscopically, hysteroscopy has become a diagnostic gold standard. Through "operative" hysteroscopes, both the electrical current of the resectoscope and the energy of the neodymium:yttrium-aluminum-garnet laser have been effective tools in many cases and presented a new alternative to laparotomy and hysterectomy. The most frequent procedures are 1) endometrial ablation and partial endometrial ablation, 2) myomectomy for submucous myomas, 3) two-step myomectomy for large submucosal and intramural myomas, 4) hysteroscopic management of müllerian defects, and 5) hysteroscopic management of intrauterine adhesions.

The 67-kd high-affinity laminin receptor (67 LR) is a gene product whose expression appears to be associated with the invasive and metastatic phenotype of a variety of human cancer cells. Northern blot hybridization has been routinely used to quantify the level of 67 LR mRNA from total cellular RNA extracts of homogenized tissue specimens or in vitro grown cell populations. This technique is useful to assess the average expression of the 67 LR mRNA of a particular sample but does not provide information about expression in specific cell types nor about heterogeneity of expression from cell to cell. In this study, we analyzed the expression of 67 LR mRNA in four human cancer cell lines with varying degrees of expression of 67 LR protein (renal cancer A-704, breast carcinoma MCF-7/4 and MCF-7/7, and pancreatic cancer Panc-1) using in situ hybridization performed with 67 LR riboprobes. Total cellular RNA was simultaneously extracted from the cell lines and hybridized on Northern blots with a 67 LR cDNA probe to assess the validity of the mRNA detection by in situ hybridization. Sixty-seven LR mRNA expression was higher in Panc-1 and MCF-7/4 cells than in MCF-7/7 and renal carcinoma A-704. There was a direct correlation (R2 = 0.88) between the in situ hybridization analysis and the mRNA levels detected by Northern blot analysis. The in situ hybridization method showed a heterogeneous expression of the 67 LR mRNA in the four cell lines with different subpopulations of cells showing a range from negative to high levels of the message. Sixteen freshly frozen human colorectal tissues (seven adenocarcinomas, five matched normal mucosae, and four adenomas) were also analyzed by in situ hybridization. The 67 LR mRNA was localized in normal and neoplastic epithelial cells. Adenocarcinoma cells showed a 1.6- to 5-fold higher expression (P < 0.02 according to the Wilcoxon-Mann-Whitney test) than did epithelial colonic cells from normal mucosae or adenomas. The signal tended to be stronger in poorly differentiated carcinomas and carcinomas with metastases than in moderately differentiated and nonmetastatic tumors. We conclude that the high expression of 67 LR mRNA in colorectal tumors is due to an increased production by tumor cells. Furthermore, in situ hybridization is an effective method to detect the expression of LR mRNA in cultured cell lines as well as in frozen tissue sections. [less ▲]

Eight respiratory-deficient mutants of Chlamydomonas reinhardtii have been isolated after mutagenic treatment with acriflavine or ethidium bromide. They are characterized by their inability to grow or their very reduced growth under heterotrophic conditions. One mutation (Class III) is of nuclear origin whereas the seven remaining mutants (Classes I and II) display a predominantly paternal mt- inheritance, typical of mutations residing in the mitochondrial DNA. Biochemical analysis has shown that all mutants are deficient in the cyanide-sensitive cytochrome pathway of the respiration whereas the alternative pathway is still functional. Measurements of complexes II + III (antimycin-sensitive succinate-cytochrome c oxido-reductase) and complex IV (cytochrome c oxidase) activities allowed to conclude that six mutations have to be localized in the mitochondrial apocytochrome b (COB) gene, one in the mitochondrial cytochrome oxidase subunit I (COI) gene and one in a nuclear gene encoding a component of the cytochrome oxidase complex. By using specific probes, we have moreover demonstrated that five mutants (Class II mutants) contain mitochondrial DNA molecules deleted in the terminal end containing the COB gene and the telomeric region; they also possess dimeric molecules resulting from end-to-end junctions of deleted monomers. The two other mitochondrial mutants (Class I) have no detectable gross alteration. Class I and Class II mutants can also be distinguished by the pattern of transmission of the mutation in crosses. An in vivo staining test has been developed to identify rapidly the mutants impaired in cyanide-sensitive respiration. [less ▲]

The structural changes of two faujasite type zeolites in the course of aromatic chlorinations by sulfuryl chloride, SO2Cl2, were investigated by X-ray powder diffraction. Both catalysts examined, the NaX zeolite, which promotes catenar side-chain chlorination, and the ZF520 zeolite, which promotes nuclear electrophilic chlorination, are strongly altered in the acidic reaction medium (hydrochloric acid and sulfur dioxide are evolved continually as the reaction proceeds). In the presence of residual humidity, progressive dealumination of the ZF520 catalyst occurs without destruction of the zeolite framework. It gives rise to the formation of an alum type structure, for which the molecular formula (H3O)Al(SO4)2.12 H2O has been suggested. Rapid degradation of the NaX zeolite is accompanied by the formation of sodium chloride and of the sodium aluminium sulfate hexahydrate, NaAl(SO4)2.6 H2O. These compounds indeed catalyze the side-chain chlorination of toluene by SO2Cl2. Under water exclusion, structural degradation of both zeolites is slowed down; formation of hydrated sulfates is prevented; however the efficiency of the catalysts is also reduced. [less ▲]

IGF-I and II genes expression has been localized by in situ hybridization in testis and epididymis of immature hypophysectomized rats treated in vivo with either pFSH, hLH, bGH, hPRL or with saline. IGF-I mRNA expression was found in both Sertoli and Leydig cells after treatment with either FSH or LH. IGF-I mRNA was highly expressed in germ cells after FSH stimulation and to a lesser extent after GH or LH treatments. However, its expression was very low in hypophysectomized control or PRL treated rats. IGF-I mRNA was also expressed in stromal cells of epididymis after LH treatment and to a lesser extent after GH stimulation. In contrast, IGF-II mRNA expression was detected in all testicular cell types whatever the hormonal treatment (FSH, LH, GH, PRL). For each hormonal treatment testicular sections were examined after immunohistochemical staining with specific antisera against IGF-I and IGF-II. Both in situ hybridization and immunohistochemical data were examined in order to determine the testicular sites of synthesis of IGF-I and IGF-II. [less ▲]

The synthesis of various [F-18]fluoroaromatic aldehydes using activated nitro precursors and aminopolyether supported nucleophilic substitution with F-18(-) is reported. These radiolabelled fluorinated aldehydes (radiochemical yields: 50-75%) are powerful key intermediates leading after treatment with NaBH4 and SOBr2 (SOCl2) to further active intermediates for example substituted [F-18]fluorobenzyl bromides (yields 30-50% EOB). These benzaldehydes and bromides are particularly useful for the preparation of new radiopharmaceuticals (e.g. fluorotroprapride, fluorodexetimide) either by reductive amination or by aromatic N-alkylation. The preparation of various amino acids in D, L (50:50) or enriched L form by asymmetric synthesis is also possible (e.g. L-6-[F-18]fluorodopa, L-4-[F-18]fluoro-m-tyrosine). It can be anticipated that the F-18-labelled fluoroaldehydes will find widespread application in radiopharmaceutical chemistry. [less ▲]

Human placental lactogen B (hCS-B) promoter activity is strongly stimulated by triiodothyronine (T3) in pituitary GC cells through interaction between the thyroid receptor and a thyroid receptor-binding element (TBE) spanning coordinates -67 to -41. This TBE is adjacent to the binding site for pituitary factor GHF1 (-95 to -68) which seems necessary for T3 stimulation of hCS-B promoter activity (M. L. Voz, B. Peers, A. Belayew, and J. A. Martial, J. Biol. Chem. 266:13397-13404, 1991). We here demonstrate actual synergy between the thyroid receptor and GHF1. Indeed, in placental JEG-3 cells devoid of factor GHF1, hCS promoter activity is barely stimulated by T3, while a strong response is observed in pituitary GC cells. In the latter, furthermore, neither the TBE nor the GHF1-binding site alone is sufficient to render the thymidine kinase promoter responsive to T3, while in combination they promote strong T3 stimulation. Close proximity between these sites is required for optimal synergy: T3 stimulation globally decreases with increased spacing. Furthermore, synergy occurs not only with a GHF1-binding site but also with all other factor recognition sequences tested (Sp1, NF1, CP1, Oct1, and CACCC boxes) and even with two other copies of the TBE. Nor is it specific to hCS TBE, since the palindromic sequence TCAGGTCA TGACCTGA (TREpal) also exhibits cooperativity. [less ▲]

Two mathematical models for the study of mesoscale (tides, storm surges ...) and macroscale (general circulation ...) motions are described. Both models are derived from the GHER 3-D baroclinic turbulent closure primitive equation model and adapted to the specific spectral windows of, respectively, mesoscale and macroscale processes. Numerical methods are discussed: 3-D finite differences, mode-splitting, sigma-transform ... The mesoscale model is applied to the simulation of the M2 tide on the North-Western European Continental Shelf. The residual circulation model is based on time averaged primitive equations which explicitly include mesoscale Reynolds stresses that are computed by the mesoscale model. Preliminary results of the application of this model in typical summer conditions are presented. [less ▲]

In summary, we established that a significant production of the monokines interleukin-6, tumor necrosis factor apha, and interleukin-1 occurred during orthotopic liver transplantation whereas the lymphokines interferon gamma and interleukin-2 were not detected. Levels of interleukin-6 reached their maximum values before and especially at the end of the anhepatic phase. They remained high after the anhepatic phase, i. e. after reperfusion of the new livers. Tumor necrosis factor alpha and interleukin-1 reached their maximum values after the anhepatic phase. Not only were interleukin-6, tumor necrosis factor alpha, and interleukin-1 present in the serum but they could also be detected in the bile produced by these new livers. Mechanisms of monokine production during orthotopic liver transplantation is multifactorial in origin and further studies will have to evaluate the relative contribution of the various factors involved. The possibility of an association between peroperative monokines and transplant outcome and their potential clinical implication will have to be elucidated. [less ▲]

A preliminary ''small-perturbation'' analytical study of a non-dissipative idealized model of the Algerian Current is made, with the aim of identifying major characteristic scales and investigating the reality of possible classical instability mechanisms. The simple configuration is shown to be stable, from a linear perturbation point of view. The GHER 3D Primitive Equation Model is then applied to a more realistic investigation of the Algerian Current. The GHER model is non-linear, three-dimensional, with turbulent closure, mode splitting and a sigma-Coordinate formulation. The numerical simulation shows the development and mature pattern of the instability in excellent agreement with the observations. The relative importance of the existence of a coastal boundary layer, the nature of the initial perturbation, baroclinic and non-linear effects on the instability mechanism is discussed. [less ▲]

Spiraeoside (quercetin-4'-glucoside) is the major and most caharacteristic flavonoid of Filipendula ulmaria flowers and is not found in the leaves and stems. This paper describes a quantification of spiraeoside by HPTLC densitometry after derivatization with diphenylboric acid -2-aminoester. The fluorescence of this flavonoid was measured at 330 nm. the spiraeoside content in batches of Filipendula ulmaria flowers ranged from 3 to 4.3 %. It is of note that these results are similar to those published elsewhere after HPLC analysis of other batches. [less ▲]

Hepatorenal syndrome (HRS) is a severe complication of liver failure with high mortality. The pathogenesis of this reversible functional renal failure is not yet clearly understood. Diagnosis is based upon the association of clinical and biological criteria. A patient was admitted to our institution for severe liver failure secondary to an exacerbation of cirrhosis, where he developed a fulminant hepatorenal syndrome. Both, the renal and hepatic failure were successfully treated by orthotopic liver transplantation. Special attention was paid to the immunosuppressive treatment with Cyclosporine whose use, we believe, should be delayed until function has partially recovered. [less ▲]

The development of glomerulosclerosis was studied in murine chronic graft-versus-host disease (GvHD), which is a model for human systemic lupus erythematosus. The authors investigated the distribution patterns of six components of the extracellular matrix (ECM), i.e., laminin, fibronectin, collagen types I, III, IV, and VI during the course of the disease. All of these ECM components except collagen type I were found in the glomeruli of normal mice, where all of them were intrinsic constituents of the mesangium. Laminin, fibronectin, and collagen type IV were also found in the glomerular capillary walls. Starting 6 weeks after the induction of GvHD and continuing at week 8, the onset of an expansion of the mesangial matrix was observed. At the same time, the amounts of laminin, fibronectin, and collagen types IV and VI increased. Ten weeks after the onset of the disease, glomerulosclerosis developed. Traces of the interstitial collagen type I were found in sclerotic glomeruli. The levels of four ECM components, i.e., collagens III, IV, VI, and laminin were markedly decreased in the sclerotic glomeruli as compared with week 8. In contrast, the amount of fibronectin in the sclerotic glomeruli increased dramatically. Immunoelectron microscopic examination showed fibronectin in the sclerotic lesions, in contrast to laminin, collagen type I, and collagen type IV. It is concluded that the sclerotic lesions in murine chronic GvHD contain fibronectin. The small amounts of the ECM components laminin, as well as collagens III, IV, and VI in the sclerotic glomeruli in GvHD, might represent remnants of mesangial material and collapsed capillary walls. These components are probably replaced by increased production and/or accumulation of collagen type I and fibronectin. [less ▲]

The set of high-resolution infrared solar observations made with the Atmospheric Trace Molecule Spectroscopy (ATMOS) - Fourier transform spectrometer from onboard Spacelab 3 (30 April-1 May 1985) has been used to evaluate the total budgets of the odd chlorine and fluorine chemical families in the stratosphere. These budgets are based on volume mixing ratio profiles measured for HCl, HF, CH3Cl, ClONO2, CCl4, CCl2F2, CCl3F, CHClF2, CF4, COF2, and SF6, near 30-degrees north latitude. When including realistic concentrations for species not measured by ATMOS, i.e., the source gases CH3CCl3, and C2F3Cl3 below 25 km, and the reservoirs ClO, HOCl and COFCl between 15 and 40 km (five gases actually measured by other techniques), the 30-degrees-N zonal 1985 mean total mixing ratio of chlorine, Cl, was found to be equal to (2.58 +/- 0.10) ppbv (parts per billion by volume) throughout the stratosphere, with no significant decrease near the stratopause. The results for total fluorine indicate a slight, but steady, decrease of its volume mixing ratio with increasing altitude, around a mean stratospheric value of (1.15 +/- 0.12) ppbv. Both uncertainties correspond to one standard deviation. These mean springtime 1985 stratospheric budgets are commensurate with values reported for the tropospheric Cl and F concentrations in the early 1980s, when allowance is made for the growth rates of their source gases at the ground and the time required for tropospheric air to be transported into the stratosphere. The results are discussed with emphasis on conservation of fluorine and chlorine and the partitioning among source, sink, and reservoir gases throughout the stratosphere. [less ▲]

The synthesis of no-carrier-added 3-[F-18]fluoroanisole, 2-[F-18]fluoroanisole, [F-18]fluorobenzene and 4-[F-18]fluoroveratrole are reported. The strategy consists of amino-polyether supported nucleophilic substitution with [F-18]F- on activated nitro aromatic aldehyde precursors followed by decarbonylation using Tris(triphenylphosphine) rhodium (I) chloride. The experimental parameters for this reaction have been studied and optimized with 2-[F-18]fluoro-4-methoxybenzaldehyde and then successfully applied to four other F-18-fluorinated aromatic aldehydes. The decarbonylation yields obtained were 84 +/- 5% (corrected for decay) within 15 min at 150-degrees-C in 1,4-dioxan. [less ▲]

We have generated 10 alanine mutants of human PRL (hPRL), a member of the PRL/GH family, to investigate the involvement of the highly conserved 58-74 region in the biological behavior of the protein. When treated with polyclonal anti-hPRL antibodies, all mutants were immunologically indistinguishable from the unmodified hPRL, and circular dichroism analyses indicated that their alpha-helix content was similar to that of the unmodified hormone. Mutations C58A, K69A, and, to a lesser extent, P66A affected drastically the ability of hPRL first to bind to the lactogenic receptor and second to stimulate the proliferation of Nb2 lymphoma cells, proving the importance of the 58-74 peptide segment for hPRL bioactivity. Binding affinities of these mutants to the Nb2 lactogenic receptor have been compared to lactogenic binding data previously obtained for several mutants of hGH. The comparison reveals that the residues involved in the biological properties of the two proteins are not at topologically equivalent positions. Hence, we suggest that the binding of these hormones to the lactogenic receptors occurs through a different molecular mechanism having distinct requirements at the residue level. [less ▲]

Two women, aged 44 and 29 years, respectively, were admitted to the hospital in early 1987 for recurrent pneumothorax, dyspnea and a diffuse reticulonodular pattern evidenced on the chest x-ray film. Lung biopsy confirmed LAM in both patients. Both were treated sequentially with medroxyprogesterone and a LHRH agonist (buserelin) to achieve reversible medical castration. Neither subjective nor objective improvement was noted after 13 and 5 months, respectively, of buserelin therapy (900 micrograms/day, nasal spray) despite an effective suppression of the pituitary-gonadal axis. Medroxyprogesterone also was ineffective. Buserelin thus failed to control pulmonary LAM in these two patients, in spite of effective medical castration. [less ▲]

Au début des années 1980, un inventaire des forêts wallonnes a été réalisé en vue de dresser rapidement, par échantillonnage systématique, un état aussi objectif que possible des ressources ligneuses régionales, principalement en termes de surfaces et de volumes sur pied. En 1990, en vue d’actualiser les données, un nouvel inventaire a été effectué sur un sous-échantillon du précédent.

Several lines of evidence suggest that dopamine might be involved in anxiety states. In this study, we assessed the growth hormone (GH) response to apomorphine (a dopaminergic agonist) 0.5 mg SC in nine drug-free inpatients meeting Research Diagnostic Criteria (RDC) for panic disorder who were age-matched and gender-matched with nine major depressive, and nine minor depressive inpatients. The three groups differed significantly in their mean GH peak response: 5.29 +/- 2.75 ng/ml in major depressives, 26.27 +/- 12.71 ng/ml in minor depressives, and 37.28 +/- 10.58 ng/ml in panics, with a significantly higher response in panic than in either minor or major depressive patients. These results support dopaminergic overactivity in panic disorder as compared with major and minor depression. [less ▲]

La superficie occupée par la culture de maïs en Lorraine belge n'a cessé d'augmenter depuis le début des années 70. Comme toutes les têtes de rotation, le maïs reçoit d'importantes quantités de fumier et de lisier. Ces concentrations élevées en matières organiques associées aux engrais minéraux sont très souvent à l'origine d'un bilan azoté déséquilibré. Dans ces conditions, les reliquats en azote généralement observés dans le sol au moment de la récolte constituent un danger réel pour la qualité des nappes phréatiques. Dans cet article, nous étudions un sous-semis de ray-grass (Lolium perenne L.). Le suivi concerne d'abord la compétition entre la culture de maïs et le sous-semis. Pour les conditions pédoclimatiques de l'essai, le sous-semis n'a pas concurrencé le maïs. L'étude porte ensuite sur l'efficacité de la technique comme moyen de lutte antipollution. Les différents profils de sol prélevés ont clairement montré l'effet d'un sous-semis, effet beaucoup plus marqué sur un limon sableux que sur un sable limoneux. [less ▲]

In this paper, we prove that if U is an increasing sequence of strictly positive and continuous functions on a locally compact Hausdorff space X such that VBAR congruent-to VBAR and C(X), then the Frechet space CU(X) is distinguished if and only if it satisfies Heinrich's density condition, or equivalently, if and only if the sequence U satisfies condition (H) (cf. e.g.`[1] for the introduction of (H)). As a consequence, the bidual lambda(infinity)(A) of the distinguished Kothe echelon space lambda-0(A) is distinguished if and only if the space lambda-1(A) is distinguished. This gives counterexamples to a problem of Grothendieck in the context of Kothe echelon spaces. [less ▲]

None produced the adhesins K99, Att25 (FY or F17) and Att111. The great majority (93.4%) of the CNF1+E coli possessed both properties. These properties allow CNF1+ to be distinguished from CNF-E coli. [less ▲]

This paper describes a new technique for locating DNA on semithin or ultrathin sections of aldehyde-fixed and plastic-embedded cells or tissues. Sections were incubated in a medium containing bromodeoxyuridine (BUdR) triphosphate and terminal deoxynucleotidyltransferase. The labeled nucleotides bound at the surface of the sections were subsequently detected with an anti-BUdR antibody and immunoglobulin-gold complex. On semithin sections, labeled nucleotide detection was achieved by an amplification step with silver enhancement. This technique was applied to a wide variety of biological materials allowing a sensitive detection of DNA-containing structures, even where these are present in very low amounts. Examples of high resolution and sensitive detection include the DNA present in mitochondria, chloroplasts, mycoplasmas, and DNA viruses. Special attention focused on the location of DNA inside the nucleolus. In Ehrlich tumor cell nucleoli, DNA was detected in the fibrillar centers and not in the dense fibrillar component. Identical results were found in the nucleoli of other cell types. These results contradict earlier data but conform with other recent immunocytochemical observations concerning the correlation between structure and function in the nucleolus. This method provides a useful tool for investigations requiring highly precise correlations between a molecular function and a given ultrastructural morphology. [less ▲]

Previous results indicate that the external glycoprotein gp51 of bovine leukemia virus plays an important role in the process of cell fusion induced by bovine leukemia virus (Bruck, C., Mathot, S., Portetelle, D., Berte, C., Franssen, J. D., Herion, P., and Burny, A. (1982) Virology 122, 342-352; Voneche, V., Portetelle., D., Kettmann, R., Willems, L., Limbach, K., Paoletti, E., Ruysschaert, J. M., Burny, A., and Brasseur, R. (1992) Proc. Natl. Acad. Sci. U. S. A. 89, 3810-3814) and suggest that a region encompassing residues 23 and 25 of gp51 is involved in this process (Portetelle, D., Couez, D., Bruck, C., Kettmann, R., Mammerickx, M., Van der Maaten, M., Brasseur, R., and Burny, A. (1989) Virology 169, 27-33; Mamoun, R., Morisson, M., Rebeyrotte, N., Busetta, B., Couez, D., Kettmann, R., Hospital, M., and Guillemain, B. (1990) J. Virol. 64, 4180-4188). X-ray diffraction studies performed on envelope glycoproteins of influenza virus indicate that the NH2-terminal part of the external glycoprotein lies very close to the fusion peptide. The same overall structure seems to exist in human immunodeficiency virus as suggested by site-directed mutagenesis followed by syncytia induction assays. Our theoretical studies indicate that a segment expanding between residues 19 and 27 of gp51 probably adopts an amphipathic beta-strand structure. We hypothesize that the amphipathic 19-27 structure of gp51 plays an important role in the process of membrane fusion by interacting with the fusion peptide or with another region of gp30. Mutational analysis disrupting the amphipathy of the 19-27 region strongly altered the fusogenic capacity of the gp51-gp30 complex. [less ▲]
