A Rel-related, mitogen-inducible, kappa B-binding protein has been cloned as an immediate-early activation gene of human peripheral blood T cells. The cDNA has an open reading frame of 900 amino acids capable of encoding a 97-kDa protein. This protein is most similar to the 105-kDa precursor polypeptide of p50-NF-kappa B. Like the 105-kDa precursor, it contains an amino-terminal Rel-related domain of about 300 amino acids and a carboxy-terminal domain containing six full cell cycle or ankyrin repeats. In vitro-translated proteins, truncated downstream of the Rel domain and excluding the repeats, bind kappa B sites. We refer to the kappa B-binding, truncated protein as p50B by analogy with p50-NF-kappa B and to the full-length protein as p97. p50B is able to form heteromeric kappa B-binding complexes with RelB, as well as with p65 and p50, the two subunits of NF-kappa B. Transient-transfection experiments in embryonal carcinoma cells demonstrate a functional cooperation between p50B and RelB or p65 in transactivation of a reporter plasmid dependent on a kappa B site. The data imply the existence of a complex family of NF-kappa B-like transcription factors. [less ▲]

GLOBOSA (GLO) is a homeotic gene whose mutants show sepaloid petals and carpelloid stamens. The similarity of Glo mutants to those of the DEFICIENS (DEFA) gene suggests that the two genes have comparable functions in floral morphogenesis. The GLO cDNA has been cloned by virtue of its homology to the MADS-box, a conserved DNA-binding domain also contained in the DEFA gene. We have determined the structure of the wild type GLO gene as well as of several glo mutant alleles which contain transposable element insertions responsible for somatic and germinal instability of Glo mutants. Analyses of the temporal and spatial expression patterns of the DEFA and GLO genes during development of wild type flowers and in flowers of various stable and unstable defA and glo alleles indicate independent induction of DEFA and GLO transcription. In contrast, organ-specific up-regulation of the two genes in petals and stamens depends on expression of both DEFA and GLO. In vitro DNA-binding studies were used to demonstrate that the DEFA and GLO proteins specifically bind, as a heterodimer, to motifs in the promoters of both genes. A model is presented which proposes both combinatorial and cross-regulatory interactions between the DEFA and GLO genes during petal and stamen organogenesis in the second and third whorls of the flower. The function of the two genes controlling determinate growth of the floral meristem is also discussed. [less ▲]

The galactose alpha 1-3 galactose (Gal alpha 1-3 Gal) residue is a carbohydrate widely distributed in many non-human mammals. Since Gal alpha 1-3 Gal residues are described on the cell surface of tumor cells, we have examined the possibility of their expression on human trophoblastic cells at different stages of placental implantation and in various pregnancy-associated conditions. Using immunohistochemical methods, Gal alpha 1-3 Gal was demonstrated on interstitial and vascular trophoblast during pregnancy. For villous trophoblast, the staining disappeared in second trimester pregnancies. The density of staining for Gal alpha 1-3 Gal was increased in highly invasive trophoblast (mole and choriocarcinoma) and decreased in poorly invasive specimens (spontaneous abortion, XO monosomia). No cells displaying Gal alpha 1-3 Gal at their surface were identified in some segments of spiral arteries from pre-eclamptic women. The anti-Gal antibody titer increased in the first trimester of pregnancy and in the sera of pre-eclamptic and eclamptic patients. These findings suggest that Gal alpha 1-3 Gal residues could be considered as markers for trophoblast invasive capacity and that the binding of maternal anti-Gal antibodies to the trophoblast could contribute to limit trophoblastic invasion and thus participate to the immunological control of implantation.

Obesity is a well-known risk factor for the development of non-insulin-dependent diabetes mellitus (NIDDM). Both insulin resistance and concomitant B-cell dysfunction are necessary for the development of NIDDM. Insulin resistance, probably genetically determined but worsened by obesity, appears to be the primary defect that leads to impaired glucose tolerance. However, B-cell dysfunction plays a critical role during progressive deterioration from mild impaired glucose tolerance to severe NIDDM. [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 ▲]

We have identified a serum-inducible gene, relB, which encodes a protein of 558 amino acids containing a region with high similarity to c-Rel and other members of the Rel family. Transcriptional activation analysis of GAL4-RelB fusion proteins in yeast cells reveals that RelB contains in its C-terminal 180 amino acids a transcriptional activation domain. The N-terminal part including the region of similarity with the Rel family shows no detectable transcriptional activity. RelB does not bind with high affinity to NF-kappa B sites, but heterodimers between RelB and p50-NF-kappa B do bind to different NF-kappa B-binding sites with a similar affinity to that shown by p50-NF-kappa B homodimers. However, RelB/p50-NF-kappa B heterodimers, in contrast to p50-NF-kappa B homodimers, transactivate transcription of a promoter containing a kappa B-binding site. [less ▲]

While neuroleptic therapy with classical compounds has frequently been associated with extrapyramidal side effects, clozapine has revealed an interesting antipsychotic profile without producing any clearcut motor side effects. However, some adverse reactions remained that stimulated the search for improved antipsychotic agents. The aim of this study was to characterize the behavioural and neurochemical profiles of typical neuroleptics (chlorpromazine, haloperidol), clozapine, and four newly synthesized clozapine-analogues. Affinity for dopaminergic (D1,D2), serotonergic (5-HT(2)) and cholinergic (muscarinic) receptors were measured and the ratios of these different binding affinities were determined and correlated with the behavioural effects of the drugs in a complex temporal regulation task in the dog. The four clozapine-analogues showed most of the behavioural characteristics previously described for neuroleptics and their neurochemical profile, particularly their 5-HT(2)/D2 pKi ratio, was compatible with an atypical antipsychotic effect. Among these drugs, JL5 and JL13 showed a high degree of similarity with clozapine. Like clozapine, they did not induce catalepsy and stereotypy/hyperkinesia. Moreover, other motor effects were also reduced (ataxia, akinesia, dystony). and tremor and sialorrhea were completely absent with these two molecules. [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 ▲]

A pharmacological manipulation of cryptocrine cell-to-cell signaling was tested by the investigation of the immunomodulatory properties of novel cyclic hexapeptide oxytocin (OT) antagonists (MSD Research Laboratories). The compounds were found to significantly inhibit the productions of IL-1ß and IL-6 elicited by anti-CD3 treatment oh human whole blood cells cultures (WBC). Cytokine productions were more significantly reduced by OT antagonists in WBC derived from female volunteers than in those obtained from male donors, suggesting an influence of sex steroids on the expression of NHP receptors by immune cells. These observations support the concept of novel immunomodulating approaches through immune-specific neuropeptide antagonists, as well as the pharmacological value of such strategies in selective immunotherapy.

Exteroceptive suppression (ES) of temporalis muscle activity, particularly the multisynaptic ES2, has been reported to be significantly reduced in tension type headache, but not in migraine. We re-evaluated the methods of optimally analysing the single shock technique and its intra- and inter-individual variability in 26 normal subjects. These data were compared with the results in patients with migraine, post-lumbar puncture headache, headache due to meningitis, tension-type headaches in HIV infection and patients with symptomatic headache of various etiologies. ES2 was absent in about 50% of tension-type headache patients, but only in one normal subject. With the methods used here and when patients with absent ES2 were excluded, mean duration of ES2 was not significantly different between the various groups. It seems therefore necessary, in spite of increased discomfort for patients, to use complementary methods, such as averaging 16-32 responses and applying various stimulation sets, if one wants to increase the potency of temporalis ES2 as a diagnostic and pathophysiologic tool in headache.

The present paper will review the main problems occurring with the classical subcutaneous insulin therapy and the possible solutions given by the use of new devices, including more particularly insulin jet injectors, pens, and portable pumps. This review has to be considered as an introduction to the presentations of this symposium devoted to implantable pumps, glucose sensors, and artificial pancreas, respectively. [less ▲]

The effects of within-sample selection on the outcome of analyses detecting linkage between genetic markers and quantitative traits were studied. It was found that selection by truncation for the trait of interest significantly reduces the differences between marker genotype means thus reducing the power to detect linked quantitative trait loci (QTL). The size of this reduction is a function of proportion selected, the magnitude of the QTL effect, recombination rate between the marker locus and the QTL, and the allele frequency of the QTL. Proportion selected was the most influential of these factors on bias, e.g., for an allele substitution effect of one standard deviation unit, selecting the top 80%, 50% or 20% of the population required 2,6 or 24 times the number of progeny, respectively, to offset the loss of power caused by this selection. The effect on power was approximately linear with respect to the size of gene effect, almost invariant to recombination rate, and a complex function of QTL allele frequency. It was concluded that experimental samples from animal populations which have been subjected to even minor amounts of selection will be inefficient in yielding information on linkage between markers and loci influencing the quantitative trait under selection.

cAMP strongly stimulates the activity of the human prolactin (hPRL) promoter. We have previously shown that two types of cis-element are required for this cAMP regulation; binding sites for the pituitary-specific factor Pit-1, and the sequence spanning nucleotides -115 to -85 (named sequence A). Sequence A contains the TGACG motif found in the consensus sequence of the cAMP-responsive element (CRE). In this study, we show that a mutation in the TGACG motif of sequence A strongly reduces not only the cAMP regulation but also the Ca2+ regulation and basal activity of the hPRL promoter. Furthermore, gel-shift assays indicate that the mutation prevents binding of a ubiquitous factor which is not the CRE-binding protein. Southwestern experiments suggest that this ubiquitous factor's molecular mass is approximately 100 kDa. We conclude that binding of a 100-kDa ubiquitous factor to sequence A is required for full basal and hormonal regulation of hPRL-promoter activity. [less ▲]

This study was to investigate whether the monofrequency forced oscillation (MFO) technique could be accurately used for pulmonary function testing in calves. The airflow resistance measured by this technique was compared to the resistance measured by the classical reference method by an in vitro study, using an artificial lung model, and by an in vivo study, using 11 healthy calves. The effect of the reference impedance of this oscillation equipment was also investigated. The results show linear relationships (r2 > 0.924, P < 0.001) in the resistance ranges 0 to 0.7 kPa litre-1 s and 0 to 1.0 kPa litre-1 s with a reference impedance of 1.0 kPa litre-1 s and 2.0 kPa litre-1 s, respectively. The MFO resistance values lower and higher than 0.4 kPa litre-1 s are slightly overestimated and underestimated, respectively. It was shown that, if some technical requirements are met, the MFO technique is a simple, reproducible, fast and accurate method which allows measurement of airflow resistance even in field conditions.

We studied 114 patients (out of a cohort of 797 consecutive patients admitted with abdominal aortic aneurysm) who were denied any immediate operation because of patient's refusal, high surgical risk, or small transverse diameter as assessed by CT scanning and ultrasonography. All patients not operated on, underwent from two to six repeated examinations during an average follow-up period of 16.8 months (range, 3 to 132). Forty-seven patients (41.2%) were subsequently operated on electively because of marked increase of transverse diameter of the aneurysm (n = 44) or for other reasons (n = 3), with a death rate of 0%. Eighteen other patients underwent emergency operation for leaking or ruptured aneurysms, and there were five deaths. The incidence of rupture was clearly related to the final diameter value, rising from 0% in aneurysms less than 40 mm to 22% in large size aneurysms (> or = 50 mm). Among the 49 patients not operated on, one died of rupture before operation and five of causes unrelated to the disease. Using individual serial measurements, we determined the linear expansion rate of the aneurysm, which proved to be related to initial diameter values: 5.3 mm/year for diameters less than 40 mm (n = 49), 6.9 mm/year in the 40 to 49 mm group (n = 41), and 7.4 mm/year for diameters of 50 mm or more (n = 24). We also fitted an exponential model to the patient data and determined in each case an "exponential" expansion rate expressed in year-1. The overall mean was equal to 0.129 year-1, and individual values were found to be independent of initial diameter size. The superiority of the exponential model over the linear model was shown to be statistically significant. Our study confirms that expansion of aneurysms is related to initial diameter values and shows that the time evolution of the disease process can be adequately described by an exponential model. It also suggests that rupture of aneurysms is not only related to their size but also to their rate of expansion. [less ▲]

X-ray diffraction analyses have been carried out on 128 samples of Miocene to Quaternary sediments from ODP Sites 794, 795 and 797. Some clay fractions of samples from Site 797 have also been studied for rare earth elements and by Nd isotopic analyses. These three sites display similar lithological and clay assemblages (with dominant chlorite, illite and smectite) showing that the sedimentation was homogeneous throughout the whole Japan Sea Basin. Three mineralogical zones are recognized. The first zone (Lower Miocene sandy clay of Sites 794 and 797) is mainly composed of chlorite resulting from hydrothermal transformation of arc-derived smectite, due to sill injections during the initial oceanic spreading stage. The second zone (Lower Miocene to Lower Pliocene siliceous claystone and diatomaceous silty clay) is dominated by arc-derived smectite; the abundance of this mineral decreases upwards while illite and chlorite increase. This trend reflects a change of detrital source, from an eastern arc-derived source (epsilon(Nd)t > -3.3; variable LREE enrichment) to a western continental crust source (epsilon(Nd)t < -9.4; shale-like REE patterns); climatic modifications in the current dynamics are proposed as a cause for this change. The third zone (Upper Pliocene to Recent silty clay with minor diatom oozes) is characterized at Site 797 by increasing amounts of illite and chlorite. This reflects a more and more important western supply which is assumed to be related to tectonic rejuvenations of the Asian margin or climatic modifications affecting the alteration conditions or the current dynamics. At Sites 794 and 795, the more or less sharp supply of chlorite seems to be driven by the incipient subduction zone on the eastern margin of the Japan Sea. [less ▲]

We studied, by means of echocardiography in vivo, the cardiac consequences of the double-muscled character selection in beef cattle. Morphologic and functional echocardiographic variables were regularly estimated in 17 Friesian and 8 Belgian White and Blue calves during their growth. A total of 50 and 44 sets of data were collected in each group, respectively. Recordings were obtained, using 2-dimensional and M-mode echocardiography, and included measurements in long- and short-axis views of the heart. Most of the diastolic measurements of the left ventricle were not significantly different between breeds when normalized for body weight. To the contrary, systolic measurements of left ventricular wall thickness and dimensions were significantly (P less than or equal to 0.001) lower and greater, respectively, in Belgian White and Blue calves than in Friesian calves. This was interpreted as a result of significantly (P less than or equal to 0.001) lower left ventricular systolic functional indices in Belgian White and Blue than in Friesian calves. Echocardiographic evidence that the double-muscled selection in cattle induces alteration in morphologic variables of left ventricle was not found. However, results indicate that indices of left ventricular systolic function are lower in double-muscled calves than in calves with standard conformation. [less ▲]

Le thymus, organe lymphoïde primaire responsable du développement des lymphocytes T, est le site d'expression de différents peptides appartenant à des familles hormonales distinctes. Le modèle classique de la neurosécrétion établi pour l'axe hypothalamo-neurohypophysaire ne peut cependant s'appliquer à la sécrétion de tels signaux par les cellules épithéliales thymiques. Un nouveau modèle de communication cellulaire, celui de la communication cryptocrine, a été proposé par John W. Funder pour décrire les échanges d'information entre une cellule épithéliale fixe et des cellules mobiles en différenciation à leur contact. Dans le thymus, la communication cryptocrine est étroitement associée à la présentation de la structure moléculaire du Soi par les molécules d'histocompatibilité (CMH) aux lymphocytes T au cours de leur différenciation. Sur la base de nos observations, le modèle du répertoire thymique des autoantigènes neuroendocrines permet de transposer au niveau moléculaire le double rôle physiologique du thymus dans les phénomènes de sélections négative et positive des cellules T, et d'apporter un éclairage nouveau sur les mécanismes responsables de la tolérance immunitaire centrale aux fonctions neuroendocrines.

Using synchrotron radiation, we have investigated the threshold photoelectron spectrum of NH3 between 10-30 eV photon energy. In contrast to the He(I)-photoelectron spectrum, the threshold photoelectron spectrum shows three bands between 10 and 21 eV. The first band is dominated by the vibrational autoionization of the 5a1, the 6a1 and the 6pe Rydberg series. Between the first and second bands a new contribution, starting at 13.26 eV, is assigned to the autoionization of (a) member(s) of Rydberg series converging to the e-1 ionization continuum. Its (their) autoionization populates the upper vibrational levels of the NH3+ (X2A1) state. From about 14.5 eV the A2E band structures are identified. However, differences between the A2E band shapes in the He(I)- and the threshold photoelectron spectra suggest that very likely autoionization contributions are involved in the latter spectrum. These phenomena could play a role in the production of the NH2+ and NH+ fragment ions. The last very weak band, at about 25 eV in the photoelectron spectrum is assigned to the NH3+(B2A1) state.

1. Reflexes were elicited in the first dorsal interosseous muscle of seven normal subjects by electrical stimulation of the digital nerves of the index finger at 3 times perceptual threshold while subjects maintained a constant voluntary contraction of the muscle. The average response in the surface-rectified electromyogram (EMG) consisted of an early inhibitory (I1) component followed by a later excitation (E2). 2. Low intensity anodal electrical or magnetic scalp stimuli were given over the motor cortex in order to elicit muscle responses within the period of the I1 and E2 reflex components. 3. Compared with control responses elicited in the absence of digital nerve stimulation, responses to electrical cortex stimulation were suppressed in the I1 period and facilitated during the E2 period of the reflex. In contrast, responses evoked by magnetic stimulation were suppressed during I1 and also for the first 10 ms or so of the E2 response. Magnetically evoked responses were facilitated during the later part of the E2 reflex. 4. Similar effects were seen when the probability of firing of single motor units was studied. 5. In three subjects, small taps were given to the abducted index finger in order to stretch the first dorsal interosseous muscle and evoke reflexes which were of comparable size to the E2 reflex evoked by digital nerve stimulation. In contrast to the experiments in which digital nerve stimuli were given, responses evoked by magnetic stimulation over motor cortex were facilitated at all times during the course of the reflex evoked when the muscle was stretched. 6. We conclude that single electrical stimuli applied to the digital nerves can reduce for a short period the excitability of motor cortex to magnetic stimulation. This occurs at a time when the same stimulus is evoking an excitatory (E2) reflex in the average surface-rectified EMG. [less ▲]

Extracorporeal shockwave lithotripsy (ESWL) has been initially designed for stones located in the kidney and the upper ureter. Our lithotripter is no exception. Its components (the table and the orientation of the semi-ellipsoid reflector) are adapted for the treatment of kidney or lumbar ureter stones. However, the elements forming the unit of treatment (the table, the C-arm and the Tripter) can be modified in such a way that focalization of stones of the lower ureter becomes possible through a perineal exposure. The aim is to avoid the pelvic bone shield while a good focalization of the stone is realized. From June 1989 to March 1991, 35 patients were treated for distal ureteric stones by ESWL in this original positioning. [less ▲]

OBJECTIVE: To elucidate some biological characteristics of peritoneal endometriosis. DESIGN: A recently advanced stereographic computer technology was applied for the investigation of the three-dimensional (3-D) architectures of peritoneal endometriosis. SETTING: University Hospital of Gynecology. PATIENTS: Biopsies were taken from 42 women with peritoneal endometriosis. Twenty-six of them were in the luteal phase. Seventeen of them received Zoladex (ICI, Cambridge, United Kingdom) for 12 weeks before biopsy. RESULTS: Two different main types could be identified according to the presence or absence of ramifications. The apparently multifocal occurrence (in 2-D) of glandular epithelium was not confirmed by the 3-D study that showed that all epithelial glands are interconnected by luminal structures in each peritoneal lesion. Stereometric study suggests a stronger effect of gonadotropin-releasing hormone agonist therapy on the stroma than on the epithelium. CONCLUSIONS: The study evaluated the 3-D architectures of peritoneal endometriosis and identified two principal types of peritoneal endometriosis. [less ▲]

We studied the substrate properties of the phospholipid-cholesterol-apolipoprotein complexes generated with apo A-I, apo A-I-CNBr fragments, apo A-II and apo A-IV for cholesterol esterification by the enzyme lecithin-cholesterol acyltransferase (LCAT). The kinetic parameters determined with the different complexes as substrates, showed that the complexes containing apo A-I and apo A-IV were about 40-times more efficient than those generated with the apo A-I fragments. In this system, the substrates containing apo A-II had the lowest efficiency. In spite of the differences in the kinetic parameters observed with the various apolipoprotein-lipid complexes, the cholesterol inserted in the complexes was esterified for more than 90% after 24 h in all systems studied. Based upon the results of the kinetic experiments, we followed the transformation of the discoidal complexes into spherical particles, due to the formation of a cholesteryl esters core, in the presence of low-density lipoproteins as an external source of cholesterol. We observed the formation of spherical particles by electron microscopy, after incubation of the discoidal complexes with LCAT for 24 h. The average percentage of cholesteryl esters in the converted particles was around 60% of the total cholesterol, varying between 40% for the apo A-I-CNBr-1-DPPC-cholesterol complex and up to 86% for the apo A-I-DPPC-cholesterol complex. The secondary structure of protein in the complexes was not significantly modified. However, the phospholipid phase transition disappeared, together with the parallel orientation of the phospholipid acyl chains with the helical segments of the apolipoproteins, as the phospholipids are organized in a monolayer at the surface of the spheres.
