The circalunidian hypothesis that tidal rhythms in coastal animals are controlled by two lunar-day (c.24.8 h) oscillators coupled in antiphase is challenged. Rhythmic locomotor activity patterns of the shore crab Carcinus maenas, and probably of some other species too, are more economically explained by interacting circadian (c.24 h) and true circatidal(More)
Respiratory currents in decapod Crustacea are produced by the rhythmic action of the exopodite (scaphognathite) of the maxilla which, in Carcinus and other crabs, is a flattened structure lying in the pre-branchial chamber in a plane roughly parallel to the direction of current flow (Borradaile, 1922). In Carcinus the action of the scaphognathite normally(More)
Sixteen patients with persistent (n = 11) or recurrent (n = 5) variceal bleeding after injection sclerotherapy and balloon tamponade were treated with an intravenous infusion of somatostatin 250 micrograms/h. Somatostatin infusion successfully controlled the bleeding in 15 of the 16 patients but one rebled after 72 h of treatment. In one patient with poor(More)
Twenty-two patients who experienced a severe haemorrhage from either oesophagitis (n = 8) or ulcers (n = 14) following injection sclerotherapy of their oesophageal varices were treated with intravenous administration of somatostatin (250 micrograms/h). Somatostatin was effective in controlling haemorrhage and preventing rebleeding in all eight patients(More)

The best general hypothesis for the control of 'spontaneous' tidal and daily patterns of behaviour in coastal animals postulates an endogenous physiological pacemaker system which generates approximate periodicity, together with environmental adjustment of the clock(s) to local time. Free-running endogenous rhythms of circatidal, circadian, circasemilunar(More)
Individuals of the shore crab Carcinus maenas were exposed to artificial cycles, applied in tidal antiphase, of pairs of the three major environmental variables that entrain circatidal rhythmicity in this species: salinity, temperature, and hydrostatic pressure. During entrainment, the observed locomotor activity patterns were dominated by exogenous(More)
In response to my advocacy of a circatidal/circadian model to explain behavioral rhythms in Carcinus (1), Palmer (2) raises questions concerning my initial premise, the nature of one of my model parameters, and the form of data analysis that I used. These questions are responded to and it is restated that the circatidal/circadian model of clock control(More)
The clinical and pathologic features of patients with cystic fibrosis are summarized, and generalized genotype or phenotype correlations are discussed in this article. Incorporation of modern molecular biologic techniques into a rapid, cost-efficient, and specific diagnostic laboratory test is outlined. The protocol for the multiplex polymerase chain(More)
