    The possible role of aero-allergens in the epidemic of asthma deaths (1981)

    Notes: The ‘epidemic’ of asthma deaths observed m the mid 1960s remains unexplained; various aetiological factors having been suggested. We suggest that aero-allergenic factors may have been important based on an analysis of aero-allergens in Cardiff over a 17-year period: a striking temporal association exists between the concentration of hyaline ascospores and increased asthma deaths. These spores, which are particularly prevalent in the summer months, have been inadequately studied as a cause of severe asthma.

    Notes: Abstract The rate equations of a restricted set of gas-phase chemical reactions occuring in an expanding circumstellar envelope are integrated numerically on the assumption that no chemical evolution has occurred in the stellar atmosphere. Abundances of all species are found to peak at a time on the order ofr 0/u 0, wherer 0 is the initial radius andu 0 the expansion velocity. After this time geometrical dilution dominates. For an initial density of 108 cm−3, on the order of 1% of hydrogen is converted to H2, and CH and CO have comparable densities of ∼10−6 relative to H, OH and O2 remain very low in abundance. For higher initial densities, H and H2 are more nearly comparable, and nearly all carbon is in CO, CH, OH and O2 remain low in abundance. The relevance of these results to M giants and other objects is discussed.

    Notes: Abstract A chemical network determining the formation and destruction of C+, C, and CO and other species is set up and applied to spherical clouds in the normal interstellar radiation field. The spherical geometry adopted gives results which are different from those for slab models. The sensitivity of chemical species to chemical and astronomical parameters is explored. The relevance of this work to the observations is discussed.

    Slow amphibian muscle fibres become less sensitive to Ca2+ with increasing sarcomere length (1983)

    Notes: Abstract Here we report that mechanically skinned muscle preparations from slow amphibian muscle fibres become less sensitive to Ca2+ when the sarcomere length is increased beyond the value corresponding to optimum filament overlap. This effect is opposite to that observed in all other studies on vertebrate myofibrillar preparations from twitch (Endo, 1972a; 1972b; Moisescu & Thieleczek, 1979; Stephenson & Williams, 1982) and cardiac muscles (Fabiato & Fabiato, 1978). This finding shows that stretch-induced increase in Ca2+ sensitivity is not a general property of the contractile apparatus and suggests that differences in the ultrastructure between these muscle fibre types could be responsible for the opposite length effects. Furthermore, these results allow a more detailed understanding of the processes behind the stretch effects observed in intact slow and twitch amphibian muscle fibres (Lännergren, 1975).

    Activation of skinned arthropod muscle fibres by Ca2+ and Sr2+ (1980)
    Springer
    Journal of muscle research and cell motility 1 (1980), S. 73-87 
    Details
    ISSN: 1573-2657
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary Mechanically skinned skeletal muscle fibres of three crustaceans (barnacle, crayfish and crab) and two insects (cockroach and cricket) were activated in Ca2+- and Sr2+-buffered solutions of different concentrations and the isometric force response was determined. The maximum force response induced by Sr2+ (P 0 Sr ) was only 0–10% of that induced by Ca2+ (P 0 Ca ) in all crustacean muscles, but approached 90% in insects. Experiments on barnacle muscle fibres activated simultaneously by Ca2+ and Sr2+ suggested that Sr2+ competes with Ca2+ for binding onto the regulatory sites without, however, being able to turn all of them ‘on’ as efficiently as Ca2+. Interestingly, the ratioP 0 Sr /P 0 Ca and the sensitivity for both Sr2+ and Ca2+ increased substantially after 4–6 h following the dissection of the animals in most intact decapod muscle fibres and after 24 h in most barnacle muscle fibres. The steepness of the activation curves for both Ca2+ and Sr2+ was similar for each muscle regardless of the age of the fibre and implied that more than 2 Ca2+ (2 Sr2+) were involved in the activation process of each muscle. A Ca2+-induced Ca2+ release mechanism of physiological importance was found to operate in all arthropod muscle fibres investigated.
