Rectal Absorption of E-2078 (Dynorphin Analogue Peptide) in Rats
No full textAbstract
The plasma levels in rats of a dynorphin analogue peptide (E-2078) after rectal administration have been studied. The bioavailabilities of E-2078 after rectal administration, subcutaneous injection, intramuscular injection, and oral administration were 21·6, 67·8, 67·1, 0·7%, respectively. The effect of dose, pH, osmolarity and viscosity on the rectal absorption of E-2078 were studied. A sigmoid relationship between the dose and the AUC was observed on rectal administration, while there was a linear relationship on intramuscular administration. The AUC was increased in acidic solution and highly viscous solution. The osmolarity did not affect the absorption of E-2078. In microscopic studies, E-2078 caused little or no damage to the rectal mucosa in rats.</jats:p
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Systemic effects of E-2078, a stabilized dynorphin A(1–8) analog, in rhesus monkeys
Full text link Rationale : E-2078 ([ N -methyl-Tyr 1 , N -methyl-Arg 7 , d -Leu 8 ] dynorphin A(1–8) ethylamide) is a dynorphin A(1–8) analog with a reduced tendency to be biotransformed, when compared to the unmodified opioid peptide. E-2078 has been found to produce κ-opioid agonist effects in vivo in rodents. Objective : In the present studies, we investigated whether systemically administered E-2078 could produce κ-agonist effects in rhesus monkeys, in tests of antinociception, diuresis and ethylketocyclazocine (EKC) discrimination. Methods : E-2078 (0.32–18 mg/kg, SC, IM or IV) was tested in the warm water (50°, 55°C) tail withdrawal assay of thermal antinociception. The diuretic effects of E-2078 (0.056– 1.8 mg/kg, SC) were also compared to those of the κ-agonist, U69,593 (0.01–0.32 mg/kg, SC). Lastly, the effects of E-2078 (0.1–3.2 mg/kg, SC or IV) were studied in rhesus monkeys trained to discriminate EKC (0.0056 mg/kg SC) from vehicle, in a food-reinforced operant procedure. Results : E-2078 did not produce thermal antinociception in rhesus monkeys following SC or IM administration, up to the largest doses presently studied (i.e., 18 and 10 mg/kg, respectively). E-2078 caused thermal antinociception by the IV route, but this effect was not apparently mediated by κ- or µ-opioid receptors, as shown by its insensitivity to quadazocine (1 mg/kg) pretreatment. However, SC E-2078 caused diuresis, and this effect was blocked by quadazocine pretreatment, consistent with mediation by κ-opioid receptors. E-2078 generalized in EKC-discriminating monkeys, but only after the largest dose (3.2 mg/kg), and only following IV administration. Conclusions : The present studies suggest that systemically administered E-2078 can produce some κ-receptor mediated effects in rhesus monkeys, but its profile of action is not identical to non-peptidic κ-agonists following all routes of administration, or across all experimental situations.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/41963/1/213-143-2-190_91430190.pd
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
