On the meromorphic and schechter-shapiro operational calculi
No full textThe well-known Dunford-Taylor operational calculus for closed linear operators in Banach spaces has been generalized in two different ways: First, by H. A. Gindler (Nagoya Math. J. 26 (1966), 31–38) and B. Nagy (Acta Math. Acad. Sci. Hungar. 33 (1979), 379–390), to include meromorphic functions with poles in the extended spectrum which are not eigenvalues. Second, by M. Schechter and J. Shapiro (Trans. Amer. Math. Soc. 175 (1973), 439–467), to include functions analytic on a neighborhood of the Fredholm spectrum. In this paper we give several results about the meromorphic calculus, in particular, spectral mapping theorems for essential spectra; and we apply our results to the study of the solutions of some integro-differential equations. Moreover, for functions admissible in both calculi, we verify that with suitable choice of quasi-resolvent and contour of integration, the Schechter-Shapiro calculus yields an extension of the operator provided by the meromorphic calculus
Involvement of 5-HT1A serotonergic receptor on Δ9-Tetrahydrocannabinol (Δ9-THC)-induced emotional response in rats
No full textThe major psychoactive constituent of cannabis, Δ9-THC, affects emotional reactivity in humans (Porter and Felder, 2001) and laboratory animals by activating brain cannabinoid receptors (Onaivi et al. 1990; Berrendero and Maldonado 2002). The 5HT system plays a key modulatory role in CNS processes that appear to be dysregulated in psychiatric disorders such as anxiety, fear, depression or aggression (Griebel, 1995). The role of 5HT1A serotonergic receptor, located in serotonergic patways projecting from mid-brain raphe nuclei to limbic areas, in the modulation of anxious states has been particularly well studied (Handley, 1995; Barnes and Sharp, 1999). To date, there is only one report on the involvement of 5HT1A serotonergic receptor in anxiogenic-like response induced by CP 55,940 (Marco et al., 2004). The aim of the present work was to further elucidate the role of 5-HT1A serotonergic receptor on emotional reactivity induced by cannabinoids in rats using the elevated plus-maze (EPM) and forced swimming test (FST). D9–THC (0.015-3 mg/kg), was studied in a EPM apparatus according to Pellow et al. (1985). The test length was 5 min, the total time spent in each arm and the number of arm entries were scored by trained observers in male Sprague-Dawley rats, 30 min after treatment. The FST, evaluated according to Porsolt et al., (1977), consisted in two swimming sessions where the time of immobility during the 2nd 5-min session was an indicator of antidepressant activity. D9–THC showed a biphasic effect being anxiolytic at a low (0.75 mg/kg) and anxiogenic at a high (3 mg/kg) dose. Lower doses as 0.015 and 0.075 mg/kg significantly reduced the immobility time in the FST, showing an antidepressant activity. Pre-treatment with the 5-HT1A serotonergic receptor antagonist, WAY 100635 (0.3 mg/kg) given s.c. 1h before D9–THC, significantly reversed its anxiolytic effect. A synergistic action on anxiolytic effect, when the 5-HT1A serotonergic receptor agonist 8-OH-DPAT (0.0075 mg/kg) was given in combination with D9–THC, was observed. These findings support a key role of 5-HT1A serotonergic receptor in the regulation of D9–THC-induced emotional states
AM 404 leads to neuroprotection against ischemia-induced neuronal injury
No full textAnandamide and 2-AG, the most endocannabinoids studied, are produced “on demand” after cerebral ischemia from membrane associated precursors (Baker et al., 2003). As soon as anandamide is released, the diffusion process is accelerated by a rapid and selective carrier system (Piomelli 2003). The development of a series of anandamide transport inhibitors, to slow its elimination and to magnify its beneficial effects, such as AM404, can provide a new tool to investigate the role of endocannabinoids (Piomelli, 2003). Since it is well known the protective role of anandamide in processes occurring during cerebral ischemia (van der Stelt et al., 2001; Berger et al, 2004), the aim of the present work was to investigate the effect of AM404 against neuronal injury in vivo. The animal model we used was the transient global cerebral ischemia induced by Bilateral Carotid Arteries Occlusion (BCAO) in mongolian gerbils. The compound was given i.p. 5 min after BCAO in a range of doses between 0.01 and 1 mg/kg. To quantify the ischemic damage we measured from 1 hour to 7 days after recirculation, electroencephalographic (EEG) mean total spectral power, spontaneous motor activity, cognitive function, rectal temperature and hippocampal neuronal count, all parameters known to be hardly influenced by BCAO (Peruche et al., 1995). AM404 antagonized hyperlocomotion, evaluated in an “activity cage” on Day 1 and the EEG flattening, on Day 7. AM 404 also induced a significant decrease of rectal temperature, within the first hour, and reversed ischemia-induced cognitive deficit, evaluated through the passive avoidance test, on Day 3. Finally, histological examination, carried out on Day 7 with cresyl violet staining, showed that AM404 protected against neuronal loss in CA1 hippocampal subfield. These results, taken together, demonstrate the anti-ischemic effect of AM 404 suggesting a protective role of endocannabinoids in events occurring during cerebral injury. Since it’s well documented an affinity for vanilloid receptors, experiments are in progress to clarify the mechanism by which AM404 shows its protective effect
Evaluating different approaches to estimating vulnerability
No full textA number of researchers have recently proposed a variety of different `vulnerability'measures designed to capture the welfare consequences of risk for poor households, and also proposed a variety of different approaches to estimating these various measures of household vulnerability. However, it's possible to `mix-and-match'estimators and measures. Here we conduct Monte Carlo experiments designed to explore the performance of different estimators with different measures, under different assumptions regarding the underlying economic environment. We find that when the environment is stationary, and consumption expenditures are measured without error, that the best estimator is one proposed by Chaudhuri (2001), regardless of what measure of vulnerability is employed. If the vulnerability measure is risk-sensitive, but consumption is measured with error, a simple estimator proposed by the authors(2003) generally performs best. However, when the distribution of consumption is non-stationary, a modification of an estimator proposed by Pritchett et al. (2000) performs best. Future research should focus on combining the efficiency of the Chauduri estimator with the good properties of the authors (in environments with measurement error), and Pritchett (in non-stationary environments) estimators. However, even with present technology estimating vulnerability is simple, and much more informative, and useful than are static poverty measures, provided one has at least two rounds of panel data.Environmental Economics&Policies,Economic Theory&Research,Inequality,Poverty Lines,Consumption
A characterization of the Schechter essential spectrum on Banach spaces and applications
No full textAbstractIn a recent article by the author (C. R. Acad. Sci. Paris Sér. I 331 (2000) 525–530; Boll. Un. Mat. Ital. (2002), to appear) the Schechter spectrum of closed, densely defined linear operators has been characterized on spaces, which possess the Dunford–Pettis property or which are isomorphic to one of the spaces Lp(Ω), p>1. The purpose of the present work is to extend this analysis to the case of Banach spaces. Further we apply the obtained results to investigate the Schechter essential spectrum of one-dimensional transport equations with different boundary conditions
Gender confirmation surgery : guiding principles
No full textBackground At this time, no formal training or educational programs exist for surgeons or surgery residents interested in performing gender confirmation surgeries. Aim To propose guiding principles designed to aid with the development of formal surgical training programs focused on gender confirmation surgery. Methods We use expert opinion to provide a “first of its kind” framework for training surgeons to care for transgender and gender nonconforming individuals. Outcomes We describe a multidisciplinary treatment model that describes an educational philosophy and the institution of quality parameters. Results This article represents the first step in the development of a structured educational program for surgical training in gender confirmation procedures. Clinical Implications The World Professional Association for Transgender Health Board of Directors unanimously approved this article as the framework for surgical training. Strengths and Limitations This article builds a framework for surgical training. It is designed to provide concepts that will likely be modified over time and based on additional data and evidence gathered through outcome measurements. Conclusion We present an initial step in the formation of educational and technical guidelines for training surgeons in gender confirmation procedures. Schechter LS, D'Arpa S, Cohen MN, et al.

Possible Z-width probe of a "brane-world" scenario for neutrino masses
No full textThe possibility that the accurately known value of the Z width might furnish information about the coupling of two neutrinos to the Majoron (Nambu-Goldstone boson of spontaneous lepton number violation) is proposed and investigated in detail. Both the "ordinary" case and the case in which one adopts a "brane-world" picture with the Majoron free to travel in extra dimensions are studied. Bounds on the dimensionless coupling constants are obtained, allowing for any number of extra dimensions and any intrinsic mass scale. These bounds may be applied to a variety of different Majoron models. If a technically natural seesaw model is adopted, the predicted coupling constants are far below these upper bounds. In addition, for this natural model, the effect of extra dimensions is to decrease the predicted partial Z width, the increase due to many Kaluza-Klein excitations being compensated by the decrease of their common coupling constant
