    Corticotrophin-Releasing Hormone Receptor Type 1: Generation and Characterization of Polyclonal Antipeptide Antibodies and their Localization in Pituitary Cells and Cortical Neurones in vitro (1996)

    Notes: Corticotrophin-releasing hormone (CRH) is a 41 amino acid neuropeptide which plays a major role in regulating the endocrine response to stress. CRH acts by first binding to specific receptors on the plasma membrane of target cells. A CRH receptor from a human corticotroph adenoma and rat brain has recently been cloned (CRH-R1). In this paper, we have chosen three different peptide sequences within the CRH-R1 molecule which bear no similarity to other members of this receptor subfamily (or indeed any known protein) and which are likely to be exposed on the surface of the native protein, for antibody production. Some of these fragments produced anti-peptide antibodies of good titre which cross-reacted with the CRH-R1 receptor expressed in transiently transfected COS-7 cells and in tissue extracts from rat cerebellum, cortex, pituitary gland and human myometrium, both in Western blots and in liquid-phase radioimmunoassay. We used immunofluorescence techniques to localize the CRH receptor in transiently transfected COS-7 cells, primary cultures of rat anterior pituitary (AP) cells, the corticotroph-tumour cells AtT20 D16–16 and cortical neurons in primary culture. Our results indicate IR-CRH-R1 receptors have a punctate distribution on the plasma membrane of AP cells and AtT20 D16–16 cells. Whilst in AP cells their appearance is a fine punctate pattern, in AtT20 cells, they appear as large patches which could account for receptor clusters. Within primary cortical neurons, their distribution does not appear to be polarized. Our results suggest that distribution of CRH-R1 receptors within the different cell-types investigated depends not only on the amino acid sequence but also on cellular factors.

    Growth rate dependence of solventogenesis and solvents produced byClostridium beijerinckii (1988)

    Notes: Summary Acidogenesis and solventogenesis byClostridium beijerinckii NRRL B-593 has been studied in batch growth, and in sucrose-limited chemostat and recycling fermentor growth. Cells grown in batch culture without pH control primarily produced either butyric and acetic acids, or these acids plus butanol, ethanol and isopropanol in ratios depending on the medium's content of reducing agent, calcium and iron. Cells in chemostat-culture at a mass doubling time (td) of 5.8 h produced primarily butyric and acetic acids at pH 6.8 and these acids plus butanol, ethanol and isopropanol at pH 4.8. Cells grown in a recycling fermentor (in which the td continuously increases) at pH 6.8 entered solventogenesis at a td of 43 h, producing primarily propanol, ethanol and butanol, along with butyric acid, but with greatly decreased production of acetic acid. Although “clostridial form” morphology, succeeded by sporulation, usually accompanied solventogenesis, the association was not invariant so that solventogenesis and sporogenesis can occur separately in this species.

    A Generalized Sampling Theorem with the Inverse of an Arbitrary Square Summable Sequence as Sampling Points (1995)

    Notes: Abstract In this article a generalized sampling theorem using an arbitrary sequence of sampling points is derived. The sampling theorem is a Kramer-type sampling theorem, but unlike Kramer's theorem the sampling points are not necessarily eigenvalues of some boundary value problems. The theorem is then used to characterize a class of entire functions that can be reconstructed from their sample values at the points tn = an + b if n = 0, 1, 2, ... and tn = an + c if n = 0, -1, -2, ..., where a, b, c are arbitrary constants. The reconstruction formula is derived explicitly in the form of a sampling series expansion. When a = 1, b = 0 = c, the famous Whittaker-Shannon-Kotel'nikov sampling theorem is obtained as a special case.

    Description / Table of Contents: Résumé On sait que la pleuropneumonie du mouton et de la chèvre cause de sérieuses pertes économiques dans beaucoup de pays, dont l'Arabie Saoudite. Une recherche préliminaire a été entreprise sur 163 chèvres et 130 moutons montrant des symptômes cliniques ou des lésions à l'autopsie. Des prélèvements du tractus respiratoire de chèvres et de moutons vivants ou abattus (respectivement 183 et 160 échantillons) ont été mis en culture pour la recherche de mycoplasmes. Sur les 343 cultures de mycoplasmes examinées, 211 souches (soit 61,5%) ont été caractérisées au point de vue biochimique. 116 souches ont pu être identifiées sérologiquement comme étantM. mycoides sub.mycoides, M. ovipneumoniae, M. conjunctivae, M. agalactiae sub.agalactiae, M. putrefaciens etM. arginini. Les autres souches de mycoplasmes n'ont pas été identifiées. La signification des souches identifiées et leur effet pathogène probable sur le tractus respiratoire des chèvres et des moutons sont discutés. Leur pouvoir pathogène demande à être expérimentalement établi avant de mettre en place un programme de contrôle de la maladie dans le Royaume.
    Abstract: Resumen Se llevó a cabo una investigación preliminar en 163 cabras y 130 ovejas las cuales mostraron síntomas clínicos o lesiones postmortem de pleuroneumonía contagiosa. Se cultivaron en medios especiales muestras patológicas del tracto respiratorio de cabras y ovejas vivas (183 y 160 muestras respectivamente. De 343 cultivos examinados, 211 (61·5%) aislamientos se caracterizaron bioquímicamente. Un total de 116 aislamientos se caracterizaron serológicamente comoM. mycoides, subsp.mycoides, M. ovipneumonia, M. conjuntivae, M. agalactiae subsp.agalactiae, M. putrifaciens yM. arginini. Los restantes micoplasmas aislados no fueron identificados. Se discute el significado de los aislamientos identificados y su posible efecto patógeno en el tracto respiratorio de cabras y ovejas. Es necesario establecer la patogenicidad experimentalmente antes de iniciar un programa de control en el Reino.
    Notes: Summary Pleuropneumonia of goats and sheep has been known to cause serious economic losses in many countries including Saudi Arabia. A preliminary investigation was carried out on 163 goats and 130 sheep which showed clinical symptoms or post-mortem lesions of pleuropneumonia. Pathological samples from the respiratory tract of live or slaughtered goats and sheep (183 and 160 samples respectively) were cultured for mycoplasmas. Of 343 mycoplasma cultures examined 211 (61·5%) isolates were characterised biochemically. A total of 116 isolates were serologically identified asM. mycoides subsp.mycoides, M. ovipneumonia, M. conjunctivae, M. agalactiae subsp.agalactiae, M. putrifaciens andM. arginini. The remaining mycoplasma isolates were not identified. The significance of the identified isolates and their probable pathogenic effect on the respiratory tract of goats and sheep are discussed. Their pathogenicity needs to be established experimentally before initiating a control programme in the Kingdom.

    Description / Table of Contents: Summary A description and a review of the Hilbert transform procedures for detecting and quantifying structural non-linearity in frequency response functions obtained during modal testing is presented in this paper. A method of minimizing the effect of residual modes of vibration, previously a problem with the numerical Hilbert transform, is also described.
    Notes: Sommario Si descrivono e si riesaminano le procedure di trasformazione Hilbert per la scoperta e la quantificazione della non linearità strutturale nelle funzioni di risposta alla frequenza ottenute durante le prove modali. Si descrive anche un metodo per minimizzare l'effetto dei modi residui di vibrazione, già problematico per quanto riguarda la trasformazione numerica Hilbert.
