    A Study of the Barium-sensitive and -insensitive Components of the Action of Thyrotropin-releasing Hormone on Lumbar Motoneurons of the Rat Isolated Spinal Cord (1993)

    Notes: The electrophysiological action of thyrotropin-releasing hormone (TRH) on rat spinal motoneurons was studied in vitro using single-electrode voltage- and current-clamp techniques. In current-clamp conditions TRH elicited a slowly developing depolarization, associated with a large input resistance increase and sustained neuronal firing; the primary metabolites of TRH were ineffective. Under voltage-clamp conditions in the presence of tetrodotoxin, TRH evoked a large inward current (ITRH; peaking at approximately –40 mV) associated with a large input conductance fall. Only 44% of cells displayed ITRH reversal; when the chord conductance values of these cells were plotted against membrane potential, a bell-shaped relation occurred, indicating voltage-dependent block by TRH of a persistent conductance active over a wide range of membrane potentials. ITRH reversal values were shifted to more positive levels in high K+ solution in Nernstian fashion; hence a large proportion of the TRH response is suggested to be mediated by the block of a K+ conductance (IK(T)). IK(T) (and its voltage-dependent block by TRH) was resistant to certain K+ channel antagonists (tetraethylammonium, Cs+, 4-aminopyridine or apamin), but was depressed by Ba2+. The Ba2+-resistant fraction of ITRH was attenuated by Cd2+, Mn2+ or Co2+, indicating that it probably involved a Ca2+-sensitive inward current. Concomitant application of Ba2+ and Cd2+ induced a near-total block of the response to TRH. It is suggested that suppression of IK(T), associated with the onset of a Ca2+-sensitive current, can explain the excitatory effect of TRH on rat spinal motoneurons.

    The quantification of free sphingosine in the stratum corneum of patients with hereditary ichthyosis (1993)

    Notes: Sphingosine is a long-chain base which provides the back-bone of all sphingolipid molecules. Free sphingosine is found in normal epidermis, especially in the stratum corneum. As a free molecule it may modify epidermal cell proliferation and differentiation through its inhibition of protein kinase C. Using a thin-layer chromatography technique we have demonstrated in vitro that the erythrodermic ichthyoses show significantly lower levels of stratum corneum sphingosine than the non-erythrodermic types. The exact in vivo significance of this finding is unclear, but free sphingosine may have an important role in determining the inflammatory component of the hereditary ichthyoses.

    Quantification of stratum corneum ceramides and lipid envelope ceramides in the hereditary ichthyoses (1994)

    Notes: Ceramides (sphingolipids) are the main polar lipids of the stratum corneum and play an important role in skin barrier function, cell adhesion and epidermal differentiation. In view of the function of ceramides in normal skin, this study aimed to assess their levels in patients with various types of hereditary ichthyosis, in which epidermal homeostasis is markedly abnormal. Stratum corneum samples were collected from 80 patients and 23 normal controls, and the intercellular and lipid envelope ceramides were analysed by high-performance thin-layer chromatography. The covalently bound ceramides (ceramides A and B) of the lipid envelope were present in all patients studied, and showed no significant differences from control samples. Total ceramides (ceramides 1–6) were decreased in bullous ichthyosiform erythroderma, which is presumably a secondary phenomenon similar to that seen in patients with atopic dermatitis. Patients with non-erythrodermic lamellar ichthyosis showed a marked decrease in levels of the important acylceramide, ceramide 1, whereas those with other types of autosomal recessive ichthyosis (limited lamellar ichthyosis and non-bullous ichthyosiform erythroderma) had mean levels similar to the controls. Ceramide 1 deficiency may therefore define a subgroup within the autosomal recessive ichthyoses. Sjögren-Larsson syndrome (SLS) shows a deficiency of both acyl-ceramides (ceramides 1 and 6), which would seem likely to disrupt the normal skin barrier function. Furthermore, glucosyl-ceramides (cerebrosides) are known to be deficient in the neural tissue of patients with SLS. The relationship of these ceramide abnormalities to the underlying fatty alcohol oxidoreductase defect remains uncertain, but they may provide an interesting link between the nerve damage and cutaneous abnormalities seen in this rare neurodermatosis.

    Quantification of n-alkanes in stratum corneum in the hereditary ichthyoses (1992)

    Notes: Summary Chromatographic assay of n-alkanes in skin showed detectable levels in normal controls and in patients with various forms of hereditary ichthyosis. Raised n-alkanes were found in some, but not all, patients with non-bullous and bullous ichthyosiform erythroderma and in individual patients with lamellar ichthyosis, ichthyosis vulgaris and Netherton's syndrome.The finding of elevated scale n-alkanes is neither consistent in ichthyosis, nor specific to any one type of ichthyosis, and n-alkane assay is not helpful in distinguishing one type of hereditary ichthyosis from another. The source of n-alkanes in ichthyotic scale and their role, if any, in the pathogenesis of ichthyosis remain obscure.

    Multiple Personalities and Dionysiac Festivals: Dicaeopolis in Aristophanes' Acharnians (1993)

    Notes: A great deal has been written recently on Aristophanes, and the Achamians in particular; inevitably, this has not produced agreement on how to interpret the plays. Among the questions to which different answers are still being given, and probably always will be, are the following: How far did Aristophanes seek to persuade the Athenians of his own political views, whatever they may have been? If there was a conflict between the presentation of his political views and the development of comic inventions or the desire to win the prize, which took precedence? Did the Athenians expect serious political persuasion in their comedies, and was Aristophanes innovative or traditional in these respects? More particularly, what were Aristophanes' attitudes to the Peloponnesian War? Did they change? How far did he seek to push a particular view in favour of making peace in any of the surviving three so-called peace plays?

    Some asymptotics for multimodality tests based on kernel density estimates (1992)

    Notes: Summary A test due to B.W. Silverman for modality of a probability density is based on counting modes of a kernel density estimator, and the idea of critical smoothing. An asymptotic formula is given for the expected number of modes. This, together with other methods, establishes the rate of convergence of the critically smoothed bandwidth. These ideas are extended to provide insight concerning the behaviour of the test based on bootstrap critical values.
