    Obtaining the Shear Stress Shear Rate Relationship and Yield Stress of Liquid Foods from Parallel Disk Data (2005)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: : In this article, Tikhonov regularization is used to process the steady-shear data generated in the parallel disk geometry by a commercial viscometer for a number of liquid foods. This way of processing parallel disk data has the advantage of being independent of any rheological model. The resulting shear stress versus shear rate relationships cover the maximum range of shear rates consistent with the experimental data. It will also be shown that if the liquid food being tested has a yield stress, Tikhonov regularization will automatically obtain an estimate of this stress. For each of the liquid foods investigated, the resulting rheological properties are used to back-calculate the torque and rotational speed data points and compare with the original experimental data.

    The vascular anatomy of the gills of the smooth toadfishTorquiginer glaber (Teleostei: Tetraodontidae) (1980)

    Topics: Biology
    Notes: Summary The branchial vasculature of the smooth toadfish,Torquiginer glaber, was studied by light microscopic examination of Microfil vascular casts, and scanning electron microscopy of critical point dried tissue and vascular corrosion casts. The anatomy of the respiratory vascular bed was similar to that described for other teleosts. An extensive non-respiratory vascular bed was also present in the gills. In each filament this comprised a series of capillaries arising mainly from the efferent side of the gill circulation (efferent filament artery, efferent lamellar arterioles, branches of the efferent branchial artery), but also from the afferent side (afferent filament artery, afferent lamellar arterioles, lamellar blood channels). The capillaries eventually connected to a system of broadly interconnected sinuses in the filament termed the central canal and the afferent and efferent companion vessels. The sinuses connected with a large subepithelial sinus and a pair of venolymphatic vessels in the gill arch. Connections between the subepithelial sinus of the arch and the anterior venous system were demonstrated. It is suggested that the non-respiratory capillaries serve a nutritive function, while the filament sinuses provide a combined venolymphatic drainage for the filament.

    Notes: Abstract The indirect immunofluorescence technique was used to determine the distribution of peptide-containing axons in the gall bladder of the cane toad, Bufo marinus. In addition, the adrenergic innervation of the gall bladder was examined by use of immunoreactivity to the catecholamine-synthesizing enzyme, tyrosine hydroxylase, and glyoxylic acid-induced fluorescence. On the basis of peptide coexistence, two intrinsic populations of neurones and their projecting fibres could be distinguished substance P neurones and vasoactive intestine peptide neurones. Neither of these two types of neurones contained any other colocalized neuropeptides. Four populations of nerve fibres arising from cell bodies outside the gall bladder were identified: nerves containing colocalized galanin, somatostatin and vasoactive intestinal peptide; nerves containing colocalized calcitonin gene-related peptide and substance P; adrenergic nerves containing neuropeptide Y; and nerves containing only adrenaline.

    Notes: Abstract The distribution and colocalization of neuropeptides and 5-hydroxytryptamine in the posterior portion of the large intestine of the toad was studied using single- and dual-label immunohistochemistry. Neurons containing colocalized galanin/somatostatin or vasoactive intestinal peptide alone were observed along intramural pelvic nerves. Some of the galanin/somatostatin neurons also contained 5-hydroxytryptamine. Synaptic boutons containing colocalized calcitonin gene-related peptide/vasoactive intestinal peptide were associated with the galanin/somatostatin neurons. The muscle of the large intestine was also innervated by axons containing galamin/somatostatin, vasoactive intestinal peptide/calcitonin gene-related peptide or vasoactive intestinal peptide alone. Nerve fibres containing calcitonin gene-related peptide/substance P, probably representing primary afferent nerves, were also associated with muscle bundles. Submucosal blood vessels carried dense plexuses of fibres containing vasoactive intestinal peptide alone or and calcitonin gene-related peptide/substance P. Adrenergic perivascular nerves also contained galanin and neuropeptide Y.

    Innervation of the gastrointestinal canal of the toad Bufo marinus by neurons containing 5-hydroxytryptamine-like immunoreactivity (1989)

    Notes: Summary The gut of the toad, Bufo marinus, was examined for evidence of enteric neurons containing 5-hydroxytryptamine-like immunoreactivity. Such neurons were absent from the stomach. They were present in the small intestine, with processes confined to the myenteric plexus. Immunoreactive nerve cell bodies lay on branches of the pelvic nerves supplying the large intestine; fibres were found in the submucosa of the posterior large intestine and in the muscularis externa of the anterior large intestine. It is concluded, on morphological grounds, that the neurons in the small intestine are interneurons, whereas those in the large intestine are postganglionic parasympathetic motoneurons.

    Immunohistochemical study of 5-HT-containing neurons in the teleost intestine: relationship to the presence of enterochromaffin cells (1988)

    Notes: Summary The formaldehyde-induced fluorescence technique had shown 5-hydroxytryptamine-containing enteric neurons in the intestine of the teleost Platycephalus bassensis, but did not reveal such neurons in the intestine of Tetractenos glaber or Anguilla australis. Re-examination of these animals with 5-hydroxytryptamine immunohistochemistry showed immunoreactive enteric neurons in the intestine of all three teleost species. The 5-hydroxytryptamine-containing enteric neurons showed essentially the same morphology in all species examined: the somata were situated in the myenteric plexus, extending down into the circular muscle layer, but none were found in the submucosa; processes were found in the myenteric plexus, the circular muscle layer and the lamina propria. It was concluded that the neurons may innervate the muscle layers or the mucosal epithelium, but were unlikely to be interneurons. In a range of teleosts, enterochromaffin cells were found in the intestine of only those species in which the formaldehyde technique did not visualize neuronal 5-hydroxytryptamine. Available evidence suggests that, in vertebrates, 5-HT-containing enterochromaffin cells are lacking only where there is an innervation of the gut mucosa by nerve fibres containing high concentrations of 5-HT.

    Evidence for 5-hydroxytryptamine in neurones in the gut of the toad, Bufo marinus (1984)

    Notes: Summary The stomach, small intestine and large intestine of the toad, Bufo marinus, were processed for formaldehyde-induced fluorescence histochemistry. After extrinsic denervation or pretreatment with 6-hydroxydopamine to remove catecholamine fluorescence, yellow fluorescence typical of 5-hydroxytryptamine was observed in neurones in the small intestine only. The cell bodies and their processes were confined to the myenteric plexus. Additional pretreatment with 5-hydroxytryptamine enhanced the fluorescence of neurones in the small intestine and revealed yellowfluorescent nerve fibres, but not cell bodies, in the longitudinal and circular muscle layers and myenteric plexus of the large intestine. No fluorescent neurones were observed in the stomach. Following reserpine treatment, which removed native yellow fluorescence in the small intestine, exposure to 5-hydroxytryptophan produced yellow fluorescence in axons in both small and large intestine; exposure to tryptophan never restored fluorescence. The neurotoxin, 5,7-dihydroxytryptamine had no effect on the distribution of yellow-fluorescent neurones in the small and large intestine. No 5-HT-containing mast cells were present in either the small or large intestine. Thin layer chromatography with three different mobile phases showed a 5-hydroxytryptamine-like compound in extracts of mucosa-free small and large intestine but not of stomach.
