    Notes: Summary Venous occlusion plethysmography has been used to measure sympathetic vasoconstrictor responses in the feet and hands to a deep breath and body cooling and to assess blood flow variability. Measurements were made in 14 non-diabetic control subjects and 52 diabetic patients, 30 of whom had evidence of peripheral neuropathy. All the measurements were significantly reduced in the feet of patients with neuropathy. Vasoconstrictor responses were not significantly impaired in the hands of these patients. Cardiovascular autonomic function was assessed in the same subjects by standard tests of reflex heart rate responses and compared to sympathetic vasoconstrictor function as determined by the response to a deep breath. Eighteen of the 30 diabetic patients with peripheral neuropathy had impairment of both cardiovascular and sympathetic vasoconstrictor functon. Five had normal vasoconstrictor but impaired cardiovascular responses and two had normal cardiovascular but impaired vasoconstrictor function. It may therefore be important to assess both systems in diabetic patients.

    Observations on size composition and breeding of Northumberland populations of Zirphaea crispata (Pholadidae: Bivalvia) (1969)
    Springer
    Marine biology 3 (1969), S. 269-275 
    Details
    ISSN: 1432-1793
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Along the Northumberland coast, Zirphaea crispata (Linné) occurs in soft shales from approximately 1 ft (0.2 m) above datum to at least 20 fathoms (37 m). It also occurs sublittorally in dumped power station fly ash wastes. The populations are polymodal. Growth rate is estimated at approximately 8 mm a year with a life span of approximately 5 years in the case of those found intertidally and 6 to 7 years in the case of the sublittoral populations. Although breeding occurs from March to October, there is evidence that there are two main breeding peaks, one from March to May and the other from August to October. Differences in shell shape between different populations can probably be explained by the differences in effort required to drill into the substratum.

    Effect of tidal submersion on lysozyme activity in Mytilus edulis and Tellina tenuis (1983)
    Springer
    Marine biology 75 (1983), S. 57-61 
    Details
    ISSN: 1432-1793
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Changes in mean style weight and in lysozyme activity of the style, digestive gland, gill and mantle of Mytilus edulis and Tellina tenuis from the Clyde Sea area, Scotland, were investigated over tidal cycles in March and August, 1981. For M. edulis, significant changes occurred in the style weight, style lysozyme activity and digestive gland lysozyme activity during a 22 h period. These appear to be related to a diurnal cycle rather than a tidal cycle. Changes in the weight of the style of M. edulis may be caused by dissolution during feeding, and style lysozyme may be secreted independently of the style matrix. The activity of lysozyme in T. tenuis is unaffected by the tide, suggesting that this intertidal bivalve can feed throughout the tidal cycle.

    Notes: [Auszug] During a survey of the sublittoral fauna of the Clyde sea area from 1949 onwards, it has been observed that the shells of many living molluscs are encrusted with a black deposit. In particular, this was the case of molluscs taken from muds and sandy-muds at depths of 15-105 fathoms. Although this ...

    Notes: [Auszug] In connexion with some investigations on the salting-out of oxygen in aqueous electrolytes, a number of determinations of the solubility of oxygen in distilled water at 25 C. were made over a period of several months. The Winkler method, modified to the extent that 0-01 N thiosulphate instead of 0 ...

    Notes: [Auszug] Barometric pressure records from both stations were sampled every 2 h throughout 1965. The year was divided into nine periods, eight of 40 days and the last one of 45 days. The analysis first estimates the autocovariance and then takes its Fourier transform to calculate the spectral density or ...
