    Notes: Background Asthma is accepted as a disease characterized by airway inflammation, with evidence that airway structural changes, or ‘remodelling’ occurs. There are few studies relating airway physiology, inflammation and remodelling, however. We have carried out a study of inter-relationships between airway inflammation, airway remodelling, reticular basement membrane (RBM) thickening, and bronchial hyper-reactivity (BHR), before and after high-dose inhaled corticosteroid (fluticasone propionate 750 μg b.d.), in a group of relatively mild but symptomatic, steroid naïve asthma patients.Methods Double-blind, randomized, placebo-controlled, parallel group study of inhaled corticosteroid (ICS) in 35 asthmatics, with bronchoalveolar lavage (BAL) and airway endobronchial biopsy (EBB) for inflammatory cell profiles and EBB for airway remodelling carried out at baseline, 3 and 12 months.Results At baseline RBM thickening was related to BAL mast cells and EBB eosinophil counts. In turn baseline log EBB EG2 eosinophil count, log%BAL epithelial cells and log RBM thickness explained 55% of the variability in BHR.Conclusion We provide new information that airway inflammation, remodelling, and BHR in asthma are inter-related and improved by ICS therapy. Our data potentially support the need for early and long-term intervention with ICS even in relatively mild asthmatics, and the need to further assess the potential merit of longitudinal BHR testing in management of some patients, as this may reflect both airway inflammation and remodelling.

    Notes: Discriminant function analyses of infection parameters of parasitic helminths revealed that abundances of seven helminth species contributed significantly to the delineation of four host populations of winter flounder Pleuronectes americanus from the central and south-west Scotian Shelf and the north-east Gulf of Maine (NAFO subdivision 4WX-5Z). These were adult digeneans, Derogenes varicus, Genolinea laticauda, Steganoderma formosum and Steringophorus furciger, metacercariae of the digenean, Stephanostomum baccatum, and larval nematodes, Anisakis simplex and Hysterothylacium aduncum. The correct classification rate was 84% overall, with Georges Bank (5Z) and Sable Island Bank (4W) winter flounder being the most accurately classified samples at 98 and 88%, respectively. Winter flounder from south-west Nova Scotia (4X), an inshore sample from St Marys Bay and offshore fish from Browns Bank, had the lowest rates of correct classification (76 and 71%, respectively) due, primarily, to cross-misclassification between the two samples. Winter pairwise comparisons of four microsatellite markers identified significant genetic differences between all populations sampled with the Georges Bank population being the most genetically distinct overall, and St Marys Bay and Browns Bank fish being the least dissimilar.

    Notes: To explore the population structure of Atlantic halibut Hippoglossus hippoglossus, 160 fish from four locations in the north-west Atlantic (Bay of Fundy, Scotian Shelf, Gulf of St Lawrence and Iceland) were examined for evidence of population structure using 18 microsatellite markers. Pair-wise FST and a model-based cluster analysis revealed no significant differentiation between samples, although uncertainties surrounding Atlantic halibut reproductive behaviour made it difficult to ascertain that only a single breeding population had been sampled at each location

    Notes: Abstract Apparent molal volumes and compressibilities are reported for dilute aqueous solutions of cyclic ethers, simple carbohydrates, and related polyhydroxy compounds. The results for carbohydrates are considered in the light of two theoretical descriptions of such systems, i.e., the semiideal solution approach of Stokes and Robinson, and the McMillan-Mayer theory ty[e of approach as employed by Kozak, Knight, and Kauzmann. It is concluded that neither model is satisfactory, and that for these solutions a specific hydration model, described in more detail in another paper, is more satisfactory.

    Notes: Abstract The effect of hydroxyl substitution on the nature of the hydration of an alkane chain has been studied by calorimetric techniques. Static permittivities (ɛ0) of a range of monosaccharides and related compounds in aqueous solution have also been determined. The (ɛ0) data, suitably processed, have provided information about the solute dipole moments. In conjunction with earlier results from volumetric, compressibility, and relaxation studies, the specific hydration model is further developed and the relationships between solute molecular conformations and solute-water interactions are discussed.

    Description / Table of Contents: Résumé Des mesures radiologiques de la masse minérale osseuse de la partie proximale du radius et l'épaisseur du muscle et du tissu graisseux sous-cutané de l'avant-bras ont été relevées chez l'homme et la femme adultes normaux. La masse minérale osseuse ne montre pas de modification significative jusqu'à 60 ans chez l'homme et 50 ans chez la femme, puis on observe une chute. L'épaisseur musculaire décroit, chez l'homme, à partir de 30 ans, alors que chez la femme on n'observe aucune modification significative avant 60 ans. Les corrélations entre ces variables diffèrent selon le sexe. Alors que la masse minérale et l'épaisseur musculaire varient positivement chez l'homme en fonction de l'âge, il n'y a pas de rapport significatif chez la femme, après 60 ans. Cependant, chez ces dernières, la masse osseuse et le tissu graisseux sous-cutané sont en corrélation nette après 60 ans, bien qu'aucun rapport significatif ne soit noté chez l'homme quel que soit le groupe d'âge. Chez des sujets ostéoporotiques, la masse minérale osseuse et l'épaisseur musculaire sont plus faibles chez les hommes par rapport à des sujets normaux du même âge. Chez des femmes ostéoporotiques, cependant, bien que la masse minérale osseuse et le tissu graisseux sous-cutané soient inférieures par rapport à des sujets normaux, l'épaisseur du muscle n'est pas modifiée.
    Abstract: Zusammenfassung Es wurden bei gesunden erwachsenen Männern und Frauen radiologische Messungen der Knochenmineralmasse im proximalen Radius, der Dicke des Muskels und des subkutanen Fettes des Vorderarmes durch die ganze Altersspanne durchgeführt. Die Knochenmineralmasse zeigte keine signifikante Veränderung bis zum 60. Altersjahr bei den Männern und bis zum 50. Altersjahr bei den Frauen; dann jedoch sank sie ab. Die Muskeldicke nahm bei den Männern über 30 Jahren ab, bei den Frauen konnte jedoch eine signifikante Abnahme erst ab 60 Jahren festgestellt werden. Die Korrelation zwischen diesen beiden Werten war bei Männern und Frauen ebenfalls verschieden. Während bei den Männern Knochenmineralmasse und Muskeldicke in jedem Alter meistens eine positive Korrelation zeigte, konnte bei den Frauen nach dem 60. Altersjahr keine signifikante Korrelation gefunden werden. Bei den Frauen zeigten hingegen Knochenmasse und subkutanes Fett eine deutliche Korrelation in der Gruppe nach dem 60. Altersjahr, während bei den Männern in keiner Altersgruppe eine signifikante Korrelation gefunden werden konnte. In einer osteoporotischen Gruppe waren Knochenmineralmasse und Muskeldicke niedriger bei Männern, verglichen mit Kontrollen bei Gesunden desselben Alters. Bei weiblichen osteoporotischen Patienten hingegen zeigte die Muskeldicke keinen Unterschied, während Knochenmineralmasse und subkutanes Fett niedriger waren als bei Gesunden.
    Notes: Abstract Radiologic measurements of bone mineral mass in the proximal radius, muscle width and thickness of the subcutaneous fat of the forearm were studied in normal men and women throughout the adult age range. Bone mineral mass showed no significant change to age 60 in men and age 50 in women, but fell thereafter. Muscle width declined from age 30 in the male population, though no significant reduction was found in women before age 60. The correlations between these variables also differed between males and females. While bone mineral mass and muscle width tended, in males, to be positively correlated at all ages, in females no significant correlation was found after age 60. In females, however, bone mass and subcutaneous fat were distinctly correlated in the over 60 age group, though no significant correlation was found in males in any age group. In an osteoporotic group, bone mineral mass and muscle width were lower in male patients than in normals of similar age. In female osteoporotic patients, however, while bone mineral mass and subcutaneous fat were less than in normals, muscle width showed no difference.

    Notes: Summary Irradiation of homogenates of etiolated barley leaves with red light resulted in an increase in the levels of gibberellin (GA)-like substances as compared to dark controls. When homogenates were fed with [3H]-GA9 there was as incorporation of the radioactivity into a number of other GA's: this process occurred to a greater extent in red light than in darkness, and could be inhibited by boiling the extract prior to addition of the [3H]-GA9.

    Notes: Summary Treatment of waterlogged tomato plants with benzyladenine relieved most of the symptoms of flooding injury. The effects of benzyladenine included maintenance of chlorophyll levels, reduced epinastic curvature of petioles, absence of adventitious roots, and stem growth greater than that of waterlogged control plants.
