Interaction of glutamate and aspartate with the oxoglutarate carrier was investigated in rat heart mitochondria or inverted submitochondrial particles. With mitochondria, glutamate and aspartate had no effect on the initial rate of oxoglutarate or malate uptake. With inverted submitochondrial vesicles, binding experiments indicated that aspartate bound to the oxoglutarate carrier on its matricial face and increased the affinity of the substrate binding site for malate but did not change the affinity for oxoglutarate. Glutamate had no effect on both substrate bindings. The dissociation constants of the binary substrate-carrier complexes on the matricial side were determined (1.28 +/- 0.15 mM for oxoglutarate and 2.22 +/- 0.26 mM for malate). These values, compared with those obtained previously on the cytosolic side of intact mitochondria, confirmed the asymmetry of the carrier in the native membrane (higher affinities on the cytosolic face). It is concluded that (1) aspartate and glutamate are not cytosolic effectors of the oxoglutarate carrier, (2) matricial aspartate is a positive effector of the binding of malate on the matricial side of the oxoglutarate carrier, and (3) such a characteristic may play a role in the regulation of the oxoglutarate carrier. Thus, it may be emphasized that (1) this observation is the first clear evidence of a well-defined 'sophisticated regulation' (allosteric) of a mitochondrial metabolite carrier, and (2) this regulation of the oxoglutarate carrier may have important consequences on the efficiency of reducing equivalent import in the matrix space by the malate-aspartate shuttle.

In the population who look advice from our interdisciplinary team, penile prosthesis is estimated been indicated in about 13% of the cases. Among these 13% of patients to whom a penile implant was proposed, only 32% agreed to undergo the operation. From this statement, we wondered why some men require penile implantation and other ones resign. A follow-up survey allowed to compare the experience of 19 implants recipients to the experience of 17 patients who have refused this solution. The cost of the device appears being a very determinant argument in the decision to reject penile implantation. Our study fails to distinguls clearly the two groups of subjects on the basis of another motivation criterion. [less ▲]

Thermal conductivity of two Bi-based high temperature superconducting ceramics, 2212 and 2223, with a markedly different microstructure have been examined. A pulse technique has been used. Depending on the heating pulse duration, the more weak-links-containing 2223 sample shows either equilibrium or nonequilibrium behavior. The temperature dependence of the thermal conductivity between 110 K and 180 K is found to obey the Arrhenius law. The experimental observations are interpreted as a thermally activated heat flux motion through the polycrystalline grain boundaries with an energy barrier of nearly 10meV. It is likely due to a phase slip mechanism. An extra relaxation process due to the pore content/structure is thus emphasized in such regimes. [less ▲]

The effects of various muscarinic antagonists on acetylcholine (ACh)-induced pulmonary oedema were studied in isolated perfused rabbit lungs. ACh induced a dose-dependent increase in the capillary filtration coefficient (Kf,c). This effect has been previously related to the activation of the capsaicin-sensitive nerve fibres and the release of substance P. Atropine, pirenzepine (M1-selective antagonist) and 4-DAMP (M3-selective antagonist) altered this response, producing a dose-dependent shift to the right of the ACh concentration-Kf,c response curve. By contrast, the M2-selective antagonist AFDX-116 shifted the ACh concentration-response curve to the left. Atropine, pirenzepine and 4-DAMP also significantly reduced the capsaicin-induced increase in the Kf,c, while AFDX-116 enhanced it. We conclude that multiple muscarinic receptor subtypes are present in the rabbit lung, located on the C-fibres, and are involved in the ACh-induced pulmonary oedema. M1 and M3 receptors seem to stimulate the release of neuropeptides from C-fibres, whereas M2 receptors have an inhibitory effect on these fibers. [less ▲]

This paper reviews the use of acarbose in the prevention and treatment of hypoglycaemia. In diet- or sulfonylurea-treated patients, acarbose may reduce the incidence of late postprandial hypoglycaemia. In insulin-treated patients, acarbose treatment usually requires reduction of the insulin dose; one study has shown that 100 mg acarbose at night significantly reduces the incidence of mid-evening and nocturnal hypoglycaemia. Several studies have suggested acarbose to be a useful adjunct to the management of reactive hypoglycaemia in the non-diabetic patients. Long-term prospective studies are still needed to document this last indication of acarbose or other alpha-glycosidase inhibitors. [less ▲]

We study the diffusion of helium and other heavy elements in the solar interior by solving exactly the set of flow equations developed by Burgers for a multicomponent fluid, including the residual heat-flow terms. No approximation is made concerning the relative concentrations, and no restriction is placed on the number of elements considered. We give improved diffusion velocities for hydrogen, helium, oxygen, and iron, in the analytic form derived previously by Bahcall & Loeb. These expressions for the diffusion velocities are simple to program in stellar evolution codes and are expected to be accurate to similar to 15%. We find that the inclusion of the residual heat flow terms leads to an increase in the hydrogen diffusion velocity. We compare our numerical results-with those obtained analytically by Bahcall & Loeb using a simplified treatment, as well as with those derived numerically by Michaud & Proffitt. We find that for conditions characteristic of the Sun, the results of Bahcall & Loeb for the hydrogen diffusion velocity are smaller than our more accurate numerical results by similar to 30%, except very near the center where the error becomes larger. The Michaud & Proffitt results differ from the numerical results derived here by less than or similar to 15%. Our complete treatment of element diffusion can be directly incorporated in a standard stellar evolution code by means of an exportable subroutine, but, for convenience, we also give simple analytical fits to our numerical results.

Expression of the gene coding for tryptophan oxygenase (TO) is switched on in rat liver about two weeks after birth. We identified two clusters of DNaseI hypersensitive (HS) sites in the TO gene upstream region; one near the promoter, the other at a distant upstream location (-8.5 kb). Hypersensitivity of upstream sites was present in adult and in 7 day old rat liver, but absent in kidney. To investigate their role in transcriptional regulation, a reporter gene controlled by both HS site regions was used to generate transgenic mice. In these animals the transgene followed the cell specific and developmental regulation of the endogenous gene: inactive after birth and active in adult liver. Transgenes containing only the promoter proximal HS site were non-functional. [less ▲]

In many instances amiodarone-induced hyperthyroidism has been reported as mild, thyroid functions returning to normal after discontinuation of the drug. Nevertheless, life-threatening amiodarone-induced thyrotoxicosis has also been described. Conventional treatments such as with antithyroid drugs (Thionamide) and corticosteroids are essentially ineffective or fail to stop the dramatic course of the thyroid crisis. This limited efficacy of medical therapy, particularly in patients with previously--neglected or unknown--thyroid disease, prompted us to intervene surgically. We report a series of six patients who underwent total or nearly total thyroidectomy as first line therapy for four of them. Surgery resulted in rapid resolution of thyrotoxicosis with an uneventful postoperative course. This approach has the advantage of immediate and safe efficacy, low risk of relapse and finally, appears to be the only antithyroid treatment that permits continued therapy with amiodarone. [less ▲]

Parameters derived from the non-invasive and simple monofrequency forced oscillation technique were compared with classical parameters of ventilatory mechanics in order to assess its usefulness for the investigation of pulmonary function in calves. To facilitate this comparison, theoretical derivations were coupled with in vitro measurements, using an artificial lung model, and with in vivo studies. These studies compared the oscillatory resistance parameters (Ros and Re) and the respiratory system compliance (Crs) against the classical pulmonary resistance (RL) and the dynamic compliance (Cdyn), respectively. Ros and Re were highly correlated (r > or = 0.87) with RL and the comparison between Crs and Cdyn gave a similarly high correlation (r > or = 0.88). Given its simplicity, its correspondence with classical parameters and its rapidity and reproducibility, monofrequency forced oscillation technique seems well suited for the investigation of pulmonary function under field conditions.

The first series shows an intense discrete are in near corotation with the planet. The maximum apparent molecular hydrogen emission rate corresponds to an electron precipitation of similar to 1 watt per square meter, which is about 30,000 times larger than the solar heating by extreme ultraviolet radiation. Such a particle heating rate of the auroral upper atmosphere of Jupiter should cause a large transient temperature increase and generate strong thermospheric winds. Twenty hours after initial observation, the discrete are had decreased in brightness by more than one order of magnitude. The time scale and magnitude of the change in the ultraviolet aurora leads us to suggest that the discrete Jovian auroral precipitation is related to large-scale variations in the current system, as is the case for Earth's discrete aurorae.

The spatial patterns of nitrate, phytoplankton size-fractionated chlorophyll a, photosynthetic pigments detected by HPLC and primary production were studied at the end of the austral summer (February–March 1991), in the Strait of Magellan to provide insight into the mechanisms governing this seemi-enclosed periantartic ecosystem. Climatological peculiarities, hydrodynamic constraints, runoff and land forcing were considered. The most important features identified for this area were the confinement of the microphytoplankton fraction to the external parts of the Strait and the rather uniform dimensional structure of the phytoplankton communities ( < 5 μm) within the internal sectors. In particular, the nanoplanktonic fraction (10 - 2 μm) comprised 33 %, while the picoplanktonic one (2 - 0.5 μm) represented 62% of the total. The concentration of active Chl. a and plant pigments detected by HPLC, nitrate and primary production showed an uneven but similar distribution, allowing for the characterization of different sectors within the Strait, according to different types and intensities of forcing factors. The different ecological sectors identified along the Strait were associated with distinct hydrographic typologies: an oligotrophic, wind-mixed coastal area, adjacent to the Pacific opening; a high runoff fjord and a divergence zone in the Andean sectors; a stratified inland sea in the basin-like part of the channel (Paso Ancho) and a shallow, tidally mixed system in the Patagonian sectors. Areas of relatively low and high phytoplankton biomass and primary production alternate along the Strait, according to the hydrographic structures of the different sectors. Phytoplankton biomass, in terms of active Chl. a (spectrofluorometric determination) ranged between 10 and 51 mg m−2 and primary production between 275 and 1170 mg C m−2 d−1. The assemblage of plant pigments detected by HPLC indicated that the high levels of phytoplankton pigments and production were most likely attributable to Chlorophytes, Prasinophytes, Prymnesiophytes and/or Gyrodinium and Gymnodinium-like Dinoflagellates that were submitted to natural senescence and to superfluous feeding activity; while, when Diatoms, Cryptomonads and Prymnesiophytes were dominant, efficient zooplankton grazing occurred and characterized a balanced food chain. The spatial distribution of the parameters considered was related to hydrologic conditions indicating a Pacific water influence in the entire channel. [less ▲]

In this paper, we present a new one-point integration method generalizing Flanagan and Belytschko's method (Internat. J. Numer. Methods Engrg. 17 (1981) 679-706) and a modification of Belytschko and Bindeman's method (Comput. Methods Appl. Mech. Engrg. 88 (1991) 311-340), both in the frame of large deformation elastoplastic analysis. These stabilization methods are combined with the radial return method used to integrate the constitutive law. Plane strain problems are first considered, and the method is then generalized to axisymmetrical situations. The explicit time integration scheme with its critical timestep is also considered. A few examples are presented that show the great time savings that can be obtained with reduced integration without any loss of accuracy, and even with a gain in the solution quality, since the underintegrated elements prove to be 'flexurally superconvergent'.

The expression of the 67-kD laminin receptor (67LR) and the 31-kD human laminin-binding protein (HLBP31), two proteins involved in cancer cell laminin interaction, was evaluated on 30 ovarian cancer specimens. Expression of the 67LR was increased (up to 2.5-fold, in 87% of the patients), while HLBP31 expression was downregulated in cancer cells compared with the normal tissue, as detected by northern blotting and immunohistochemistry. The immunohistochemical study demonstrated that the 67LR was significantly overexpressed (P < 0.05) in the group of patients whose cytoreductive surgery was suboptimal, and those with poor clinical outcome. No correlation was observed between HLBP31 expression and clinicopathological features. Increased expression of the 67LR appears to correlate with the invasive phenotype of ovarian cancer cells and suggests a role of the latter in ovarian cancer invasion. [less ▲]

We analyzed by different cytochemical and immunocytochemical approaches the biochemical compositon of coiled bodies in three different cultured cell lines. Coiled bodies are stained by the AgNOR staining method and by the EDTA regressive staining method preferential for ribonucleoprotein (RNP). Using the in situ polyadenylate nucleotidyl transferase-immunogold technique or anti-RNA antibodies, we decisively demonstrated the presence of appreciable amounts of RNA in coiled bodies. Neither the in situ terminal deoxynucleotidyl transferase-immunogold technique nor anti-DNA antibodies revealed any DNA in coiled bodies. Coiled bodies thus appear as distinct regions of cell nuclei involved in some steps of RNA metabolism but not directly in RNA synthesis. Their relationships with the dense fibrillar component of the nucleolus and with interchromatin granule clusters are discussed. [less ▲]

During an oceanographic cruise, carried out at the end of the austral summer (February-March 1991) in the Strait of Magellan, spatial patterns of size-fractionated chlorophyll and primary production were studied in relation to hydrographic patterns. Phytoplankton biomass, in terms of active Chl a, ranged between 10 and 51 mg m-2 and primary production between 275 and 1 170 mg C m-2 d-1. The most important features concern the confinement of the microphytoplanktonic fraction to the Pacific opening and to the embayements between the two Narrows. In the internal part of the Strait, an uniform dimensional structure (< 5 um) of phytoplankton communities was observed, with the picophytoplanktonic fraction always dominant. [less ▲]

Objective: To evaluate the role of GnRH agonist (GnRH-a) and/or drainage in the management of large endometriomas. DESIGN: This prospective clinical study was conducted in a parallel and randomized design. SETTING: Department of Gynecology, Cliniques Universitaires St. Luc, Brussels, Belgium. PATIENTS: Eight infertile women with laparoscopically confirmed ovarian endometriotic cysts. After laparoscopic drainage of the ovarian cyst, patients were randomized. Patients in group I (n = 40) received no therapy. Patients in group II (n = 40) received GnRH-a therapy for 12 weeks. A second-look laparoscopy was performed after 12 weeks in each woman. RESULTS: After drainage, a quick recurrence of the endometrial cyst was observed in only group I. Indeed, the score and the cyst size were similar to the values observed before the first laparoscopy. In group II, a significant decrease in score and cyst diameter was observed. Ovarian biopsies revealed significant reduction in the stromal vascularization and a significant reduction in the mitotic activity in the group of women treated with GnRH-a. CONCLUSION: The quick recurrence of the ovarian cyst after drainage proved that drainage alone is ineffective. Drainage followed by GnRH-a was effective in the reduction of cyst size and the glandular mitotic activity. [less ▲]

The proximal point algorithm has known these last years many developments connected with the expansion of the variational convergence theory. Motivated by this fact and inspired by the work of A.

We study the perturbed version of this algorithm and establish a critical comparison with the perturbed proximal point algorithm. We apply this new algorithm to convex optimization and to variational inclusions or, more particularly, to variational inequalities. [less ▲]

RelB belongs to the family of Rel-related proteins, dimers of which determine NF-kappa B activity. The murine RelB protein has been reported to be a dimerizing partner in kappa B-binding complexes which are capable of transactivation. On the other hand, the I-Rel protein, the presumed human homolog of RelB, was proposed to be an inhibitor whose presence in dimeric complexes interfered with their kappa B binding and therefore interfered also with transactivation. We demonstrate that human RelB (I-Rel) forms with p50 and p52 (p50B) kappa B-binding heterodimeric complexes which potently transactivate kappa B-dependent constructs in transfection studies. It is concluded that human RelB (I-Rel) and murine RelB can both function as transactivators and that no significant species-specific differences exist. [less ▲]

The time spent under a shelter by 8 grazing fattening bulls of the Belgian Blue breed was recorded during 35 days using a time-lapse recorder with IR illumination. The observation period was divided into 166 hours with rain (20 %) and 674 hours without precipitation (80 %). An occupation rate was calculated for each hour as the sum of the time spent under the shelter by each of the 8 bulls divided by 480 (8 animals x 60 minutes). The average occupation rates were 15.4 +/- 29.1 % for the hours with rain and 4.5 +/- 14.8 % for the hours without precipitation (P<0.001). The occupation rate was significantly influenced by intensity and duration of the rain : the occupation rate being higher during rainfall than with dry weather when the intensity of the rain was at least 0.4 l/m2 and the duration more than 2 hours. There was no significant difference between the live weight gain of the animals with a shelter and of other bulls grazing on an adjacent pasture without shelter. Our observations suggested however that a shelter may improve the welfare of the animals. [less ▲]

The chloroquine-resistance of Plasmodium falciparum appeared first in Southeast Asia and South-America during the sixties. It reached further the african continent in 1977, through Kenya and Tanzania. In Africa, the front of the resistance spread from East to West, and now completely covers Black Africa with different degrees of resistance. Rapidly, "in vivo" and "in vitro" tests were developped to assess the sensitivity of P. falciparum strains against the different antimalarial drugs.

The lack of hemoglobin and of carbonic anhydrase in the blood of icefish suggest that substantial adaptations of the acid-base balance should occur in order to ensure blood pH homeostasis. The level of peptidic histidyl and of reactive -SH groups per unit of body mass in icefish plasma are 12-13 times higher that those of Notothenia rossii, a common red-blooded Antarctic species. It is proposed that the high level of imidazole ring in icefish plasma improves the non-bicarbonate buffering capacity and that the reactive sulfhydryls are involved om a redox buffer as in some other hypoxia tolerant species. After plasma fractionation on Ultrogel AcA 34, the two main icefish serum proteins have been purified by DEAE cellulose chromatography (IFI) and by HPLC on anion exchange column (IF2). IFI has been identified as a cysteine-rich para-albumin and IF2 as an histidine-rich immunoglobulin-like protein. [less ▲]

According to Einstein's general theory of relativity, a gravitational field bends electromagnetic waves in much the same way as low atmospheric air layers curve the trajectory of a propagating light ray. Large mass concentrations in the universe can thereby act as a type of lens, a gravitational lens. After briefly reviewing the history of gravitational lensing since the early thoughts of Newton in 1704 until the serendipitous discovery of the first gravitational lens system in 1979, the authors recall the basic principles of atmospheric and gravitational lensing. They then describe a simple optical gravitational lens experiment which has the merit of accounting for all types of image configuration observed among currently known gravitational lens systems. Various types of gravitational lens models are described in detail as well as the resulting image properties of a distant source. An updated list as well as colour illustrations of the best known examples of multiply imaged quasars, radio rings and giant luminous arcs and arclets are presented. Some of these observations are discussed in detail. Finally, the authors show how it is possible to use gravitational lensing as a cosmological and astrophysical tool, the most interesting applications being the determination of the Hubble parameter H[SUB]0[/SUB], the mass of very distant lensing galaxies as well as the distribution of luminous and dark matter in the universe. They also show how to determine the size and structure of distant quasars from observations of micro-lensing effects. [less ▲]
