Experiments were conducted to further characterize the age-related decline in reproductive capability previously described in the male Japanese quail. Behavioral testing of a large number of males in several age groups confirmed earlier results that showed a significant reduction in courtship and mating behavior by 80 weeks of age. Intact males, 78 weeks of age, that showed no reproductive behavior were given Silastic implants containing testosterone. This treatment restored behavior in 80% of the males. Gonadal regression induced by exposure to shortened photoperiod followed by transfer to a stimulatory photoperiod did not successfully restore the endocrine or behavioral components of reproduction. Males of two age groups, 42 and 208 weeks of age, were categorized as behaviorally active or inactive and then castrated. Eight weeks later they were given implants containing testosterone. Older males required longer exposure time to the exogenous steroid and in some cases, an additional implant to restore mating behavior as compared to younger males. The presence or absence of behavioral activity prior to castration did not affect the length of time required for restoration of behavior. Challenge with exogenous luteinizing hormone-releasing hormone revealed that there was reduced release of luteinizing hormone in aged, behaviorally inactive males as compared to young males. Results of these experiments in addition to previous data give evidence that age-related changes occur at the level of the hypothalamus and pituitary as well as at the level of the gonads. [less ▲]

Follicular dendritic cells (FDC) are able to fix high amounts of immune complexes by C3b or Fc receptors without endocytosis and for long periods of time. In order to determine the function of this retention, we analysed the secretion of prostaglandin E2 (PGE2) by FDC in vitro; indeed, it is well-known that immune complex fixation on cells may induce PGE2 production. FDC were isolated by enzymic digestion of lymph follicles dissected under the biomicroscope from human tonsils or adenoids. Isolated FDC appeared as spherical clusters where they enveloped lymphoid cells with their cytoplasmic extensions. Tests were performed in synthetic culture media or in media supplemented with foetal calf serum. PGE2 production in FDC suspensions was compared to that of lymphocyte or macrophage-enriched populations prepared from the same human tonsils. In all experimental conditions, FDC and macrophage-enriched cell populations produced high levels of PGE2, inversely to lymphoid cell populations. This secretion was inhibited by indomethacin. At the ultrastructural level, we also showed that 3H-arachidonic acid was metabolized in cell membranes of all three cell types. The PGE2 produced in the culture media, according to our experimental conditions, do not influence cell proliferation, as assessed by 3H-thymidine incorporation tests on phytohaemagglutinin-stimulated lymphocytes.

This paper studies the level of concentration of several agricultural products exports whose roles are important in developing countries. The Gini index was determined as it measures the level of competition within the different markets. After a description of the index, eight products were studied : bovine meat, poultry meat, eggs in the shell, rice, sugar, tea, rubber and palm oil. For each of them, the Gini index was calculated according to the data of the Food and Agriculture Organization in 1965, 1970, 1975, 1980 and 1985. A comparison was made between the years 1965 and 1985 in order to show the evolution of the relative importance of the different exporting countries. ln conclusion, the successes, failures or changing goals of the agricultural policy of these countries could be evaluated.

The cytoarchitectural analysis of the preoptic-anterior hypothalamic region of the Japanese quail reveals a sexual dimorphism in the total volume of the medial preoptic nucleus (significantly larger in males than in females). Different nuclei of the region (dorsal preopticus, suprachiasmaticus) do not show any statistically significant difference. The sex-related difference is more consistent comparing the distribution of dark volume. This last is due to a larger number of cells containing high amount of Nissl's substance in male than in female. Present findings represent the first example of sexual dimorphism in the avian hypothalamus. [less ▲]

Using monoclonal anti-trinitrophenyl (TNP) antibodies complexed to TNP-myoglobin-coated gold particles, we analysed at the ultrastructural level the retention by follicular dendritic cells (FDC) of immune complexes containing various antibody isotypes. Gold-labelled immune complexes were injected subcutaneously or intravenously into naive mice and, after 24 h, germinal centres of draining lymph nodes or spleen were examined by electron microscopy. FDC generally retained complexes containing IgG2a and IgG2b better than those formed with IgG1 or IgG3. IgM was rarely retained. FDC isolated from lymph nodes or spleens were incubated in vitro with gold-labelled complexes in a serum-free medium. IgG2a and IgG2b complexes were also retained in vitro in large quantities by FDC; IgG1 and IgG3 complexes were retained in smaller quantities or in highly variable quantities compared with IgG2; IgM complexes were rarely seen on FDC. There was no difference between FDC isolated from lymph nodes or from spleen with respect to the Ig isotypes required for Fc-mediated retention of immune complexes. [less ▲]

Plasmatic immunoreactive trypsin (IRT), thromboxane and trypsin-like enzymatic activity were measured in 117 patients at risk of developing adult respiratory distress syndrome (ARDS) (53 multiple injury, 30 abdominal surgery, 17 acute pancreatitis, 12 burnt and 5 disseminated intravascular coagulation patients). 69 of these patients developed ARDS. Immunoreactive trypsin and thromboxane were measured by radio-immuno-assay and trypsin-like enzymatic activity by spectrophotometry, using a specific chromogenic substrate. Mean IRT value was 675 ng/ml in ARDS and 265 ng/ml in non ARDS patients (p less than 0.05). Mean IRT value was 685 ng/ml in septic and 170 ng/ml in non septic patients (p less than 0.01). An abnormal trypsin-like enzymatic activity was measured in 26 ARDS patients. In 60 patients (37 ARDS and 23 non ARDS), thromboxane appeared in plasma simultaneously or about 24 hours after the beginning of IRT release. The importance of thromboxane release parallels the intensity of IRT. Originating from pancreas, trypsin can appear in plasma either by absorption from gastrointestinal tract or after pancreatic ischemia. [less ▲]

We have theoretically studied the electronic autoionization between 17 and 18.3 eV of Rydberg series converging to the B 2Sigma+ state of CO+ (RB series). We have obtained partial and vibrationally resolved differential and total photoionization cross sections by combining ab initio electronic quantities with a variant of the two-step multichannel quantum defect theory (MQDT). The formalism of the Feshbach projection operators is used to separate the electronic quantities needed in the first and second steps of the MQDT. We have introduced the vibrational motion within the Condon approximation. Our results lead to new unambiguous assignments of the RB series. The vibrationally resolved cross sections, the associated branching ratios, and the background and resonant features are discussed in detail and compared with the available experimental data. There is an overall agreement between theory and experiement except for the angular distribution of photoelectrons. [less ▲]

Contingent negative variation (CNV), an event-related slow cerebral potential, was analyzed in 79 consecutive headache patients. Compared to normal controls (n = 33), CNV did not differ in tension headache (n = 21) or in combined headaches with a predominant tension component (n = 13). The mean amplitude of CNV was significantly (p less than 0.001) increased in migraine (n = 29) as well as in combined headache with predominant migraine (n = 16). All migraineurs were studied between attacks and without prophylactic treatment. CNV may be a useful diagnostic test in headache. Its increased amplitude in migraine might reflect central catecholaminergic hyperactivity. [less ▲]

Essai de typologie industrielle des communes belges La typologie industrielle proposée dans cet article est sans conteste le premier essai de classification des communes belges intégrant à la fois l'importance du fait industriel dans la commune et le type d'industries présentes. Au départ des 36 données sélectionnées dans les statistiques du Cadastre et de l'O.N.S.S., 11 variables ont été construites. L'analyse en composantes principales a permis d'individualiser quatre facteurs rendant compte de près de 80% de la variation totale; ces quatre composantes sont représentatives de la grande industrie, de l'industrie légère, du poids industriel (part relative de l'industrie dans la commune) et des fabrications métalliques. Sur base des scores obtenus sur ces quatre composantes, il a été ensuite possible d'établir une typologie des communes en huit classes ayant chacune un profil précis, profil qui, par ailleurs, oppose sou¬vent Flandre et Wallonie, communes rurales et centres urbains.

Serum total creatine kinase (CK), CK-MB and myoglobin (Mb) were serially determined in 17 patients who underwent endomyocardial biopsy. Mean total CK levels increased from 36 +/- 27 U/l 30 min before biopsy to a maximum of 112 +/- 77 U/l 8 h following the procedure (p less than 0.05). Similarly, Mb concentrations rose from 57 +/- 55 micrograms/l to 119 +/- 57 micrograms/l 30 min after biopsy (p less than 0.05). Normalization of total CK and Mb levels occurred within 16 and 8 h, respectively. A new immunoenzymetric assay (IEMA) was used to measure the mass concentration of the CK-MB molecule. The initial CK-MB levels were 0.2 +/- 0.4 microgram/l; a small but significant elevation was recorded as early as 2 h after biopsy (1.6 +/- 1.5 micrograms/l, p less than 0.05). CK-MB returned to initial concentration 16 h after the beginning of the procedure. Comparison with the maximum CK-MB levels recorded in 16 myocardial infarction patients (258 +/- 172 micrograms/l, range 90-680 micrograms/l) indicated that the modest increase of CK-MB level detected after biopsy probably reflects a limited endomyocardium lesion at the sampling site, excluding any significant myocardial damage. Total CK and Mb, which showed more pronounced elevations than CK-MB, are likely to originate from other sources than the myocardium. [less ▲]

A new solid-phase enzyme immunoassay measuring the gelatin-binding capacity of plasma fibronectin has been developed. This assay is based on the direct and high-affinity interaction between fibronectin and gelatin coated to polyvinyl chloride plates. The amount of fibronectin bound to gelatin is then measured by sequential incubation with a specific rabbit anti-human fibronectin antiserum, with horseradish peroxidase-conjugated goat anti-rabbit IgG antibodies and with substrate. The final degradation of the substrate is read at 492-650 nm in an ELISA processor. The assay allows the accurate detection of fibronectin concentrations ranging from 1 to 20 micrograms/ml, is inhibited by the addition of gelatin to plasma, is highly reproducible (interplate CV less than 10%), requires 100 microliter of plasma only and has been fully automated. Significant linear correlations were noted between total antigenic fibronectin (measured by laser nephelometry) and fibronectin gelatin-binding capacity in plasma from 310 blood donors. Both parameters were higher in men than in women and significantly increased according to age. Dissociation between immunoreactive fibronectin and fibronectin gelatin-binding capacity was observed in two polytraumatized patients. This enzyme immunoassay therefore provides a new method to investigate functional alterations of the gelatin-binding domain of fibronectin in various pathological conditions. [less ▲]

Thirty-three patients with common migraine underwent contingent negative variation (CNV) recordings before receiving prophylactic beta-blocker treatment with either metoprolol (27 patients) or propranolol (6 patients) at mean daily dosages of 110 mg and 122 mg, respectively. After 3 months the therapeutic efficacy of the beta-blocker was assessed in each patient by means of a global severity score and compared with the initial CNV recordings. The mean clinical improvement was 62%. A significant positive correlation was found between CNV amplitude before prophylaxis and the clinical response to beta-blockers: patients with higher CNV tended to respond better to therapy. Eight of 10 patients with a CNV amplitude higher than -25 microV had a more than 50% reduction of the severity score--that is, a good or excellent response to the beta-blocking agent--whereas only 2 of 9 patients with an amplitude lower than -20 microV had a good response.

Under certain pathological conditions the binding of various substances by serum proteins is altered. The plasma concentrations of alpha 1-acid glycoprotein, also known as orosomucoid are reported to be elevated in stressful situation and in certain disease states like acute myocardial infarction. The binding of aminopyrine to serum proteins and alpha 1-acid glycoprotein was determined using equilibrium dialysis. It appears that alpha 1-acid glycoprotein has specific binding sites for aminopyrine. Aminopyrine was also bound to other serum proteins. On addition the results indicate that an increase of alpha 1-acid glycoprotein to concentrations such as those seen in some pathological states does not really alter the percent of aminopyrine bind to serum proteins.

The main purpose of this critical overview of current knowledge in the field of the development of timing behavior in young children is to pave the way of future research. Traditional psycho-physiological methods have supplied coherent data on the estimation and perception of duration in children over age six. Only a few unsystematic studies have dealt with early temporal conditioning. To determine whether complex temporal regulations in the adult human are the result of a continuous process, deriving from elementary forms of temportal organization of activity, much more data are needed on infant adaptation to time, as well as on the role of language and capacities for inhibition in the evolution of temporal behavior. Furthermore, studies on the physiological bases of internal timing mechanisms and the ontogenesis of temporal regulation in young animals should help to assess the relative weight of early experience, maturation and cognitive development in the child.

The unexpected rediscovery of the Uranian rings in 1977 and the discovery of the faint Jovian rings in 1979 led to an intensified search for rings around Neptune. A description is given of observing programs at the European Southern Observatory (ESO) in Chile, which led to a discovery of such a ring, taking into account the utilization of the ESO 0.5 m and 1 m telescopes. The discovery is based on observations made on the night of July 22, 1984, in connection with a stellar occultation by the planet. Explanations for the observed differences in shape and timing of the occultation event, as recorded by both telescopes, are discussed. The obtained conclusions could be confirmed by a study of the results of a group of American astronomers working at the Cerro Tololo observatory. The observations strongly favor the existence of, at least, a part of a ring which has a width of roughly 10-15 km over a length of at least 100 km. [less ▲]

The authors report visual estimates and photometric observations in various wavelength ranges of the irregular variable V348 Sgr. They cover dramatic drops of brightness (from V â 12.5 to â 18) which occurred in 1972, 1973 and 1981 with a time scale much shorter than the characteristic time mentioned by previous observers. These deep minima are, to our knowledge, the best followed up to now. The maximum brightness of the object seems also to correspond to V â 12 and not 10.5 as reported earlier. The minima reach V â 18, but this might represent the nebular contribution while the star itself might even go fainter. The main conclusions of this compilation are probably that the characteristic times given by Herbig (1958) from appearances on Harvard plates are most likely incorrect and that it is impossible to give one at all. The field of V348 Sgr has also been observed in the uvby system and a sequence is provided in this paper. [less ▲]

The crystallographic structure of the penicillin-sensitive D-alanyl carboxypeptidase-transpeptidase from Streptomyces R61 has been solved to 2.8-A resolution. The 38,000-dalton serine peptidase has two regions of secondary structure, an alpha/beta cluster, and a region which contains five helical segments. The beta sheet is composed of five beta strands. The tertiary structure has no homology with the classic serine proteases or with the zinc carboxypeptidases. The binding at a common site of three types of beta-lactam (a penicillin, a cephalosporin, a monocyclic beta-lactam) and a desazacyclobutanone has been observed in Fourier difference maps. The binding site sequence is Val-Gly-Ser-Val-Thr-Lys. The beta-lactam ring lies near the enzyme's catalytic serine at position 37, and the C3 substituent of a cephalosporin falls near lysine 40.
