Identification and antimicrobial susceptibility patterns of Staphylococcus spp. isolated from canine chronic otitis externa
Silva, N.;
Arquivo Brasileiro de Medicina Veterinária e Zootecnia , 2001, DOI: 10.1590/S0102-09352001000200001
Abstract: swab samples obtained from 96 dogs with chronic otitis externa were cultured for the isolation of staphylococcus species. of 57 staphylococcal strains, 41 (72%) were coagulase-negative (cns). the identification of staphylococci strains was made by standard procedures for the routine identification of staphylococci in clinical practice. s. sciuri was the most frequent species isolated (22.8%) from chronic otitis externa in dogs followed by s. intermedius (12.3%), s. auricularis (10.5%) and s. aureus (8.8%). three (5.2%) cns strains could not be identified. bacterial isolates were susceptible to enrofloxacin, gentamicin, cephalothin, chloramphenicol and neomycin. resistance was most common to penicillin g, oxacillin and ampicillin.

Indicator of Agriculture Vulnerability to Climatic Extremes. A Conceptual Model with Case Study for the Northeast Brazil  [PDF]
Bruce Kelly N. Silva, Paulo Sergio Lucio
Atmospheric and Climate Sciences (ACS) , 2014, DOI: 10.4236/acs.2014.42034
Abstract:

The Northeast Brazil (NEB) is known for its temporal and spatial variability of precipitation. Several studies have investigated this variability in order to understand the damaging episodes such as droughts and floods. The phenomenon of drought in the NEB is a complex topic due to affecting millions of people and being the object of study in several fields of knowledge. One way to try to argue about this phenomenon is through the concept of vulnerability. The “operability” of this broad concept in natural disasters is a complex task. In order to measure an indicator of vulnerability it is necessary large amount of data from different areas of knowledge, among which include: meteorology, socio-environmental, economic, public health, among other areas. The main objective of this study is to create an index of vulnerability to climate extremes (drought and flood) for the NEB and to compare this rate with those found in the scientific literature. The data that will be used in this study are from ANA (Agência Nacional das águas), IBGE (Instituto Brasileiro de Georgrafia e Estatística), and Ministry of National integration.

El derecho internacional y las víctimas de crímenes de guerra en Colombia*
Estupi?án Silva,Rosmerlín;
Revista de Derecho , 2012,
Abstract: the concept of victim of war crimes has been the subject of major international developments. nevertheless, the victims of war crimes in colombia are subjects of parallel statutes that incorporate the content of state obligations, leaving, in some cases, a national margin of appreciation that exceeds the limits imposed by international law . the verification of the circumstances and content requires a kind of applied research in comparative law from the international criminal law and criminal law in colombia, including a review of what has been written to date on the subject and a specific case law study in the field.
EL EFECTO PLACEBO EN LOS ENSAYOS CLíNICOS CON ANTIDEPRESIVOS
Silva Ibarra,Hernán;
Acta bioethica , 2009, DOI: 10.4067/S1726-569X2009000200007
Abstract: recent studies determined that antidepressives of new generation were inadequate for moderate or severe depressions. the improvement these diseases show with medication or with a placebo isn?t very different, according to statistics. antidepressives seem to be efficient only upon patients that present an extreme depression. nevertheless, the apparent efficiency upon this group wouldn?t be due to the medication itself, but to a minor response to the placebo. another group of researchers came to very different conclusions employing a similar methodology. they assured that all antidepressives were superior compared to the placebo, although their real effect would be even minor if analysis of studies not yet published were included. this situation shows the difficulties the investigation on psychoremedies for depressions present and it revives the polemics about the utility and the ethical justification of employing placebos in this type of studies.
LA NOCHE BUENA EN LA ALAMEDA: DESCRIPCIóN DE UNA TRADICIóN EN TIEMPOS DE MODERNIZACIóN. SANTIAGO DE CHILE, SEGUNDA MITAD DEL SIGLO XIX
SILVA GUZMáN,ELISA;
Historia (Santiago) , 2012, DOI: 10.4067/S0717-71942012000100007
Abstract: the celebration of christmas eve on the alameda was one of the most important moments of the year in santiago during the second half of the nineteenth century. this article describes the evolution of this celebration from its materiality using press coverage from the time together with other written and visual sources. through a series of chronologically organized "scenes" we have a more detailed picture of the effects that the modernization process had on the daily lives of santiaguinos in their practices as well as in their aspirations. christmas commerce and the urban spaces where it took place provide an insight into how foreign influence fit between traditional practices amidst a constant social dispersion.
DEL ANACRONISMO EN HISTORIA Y EN CIENCIAS SOCIALES
Silva Olarte,Renán;
Historia Crítica , 2009,
Abstract: this article briefy examines a subject repeatedly addressed by historians: the anachronism. called the historian's "sin of sins" by lucien febvre, the article shows the current relevance of this issue and underscores the need to be continuously vigilant with respect to this obstacle to historical understanding, particularly since it is capable of assuming the most surprising forms.
La política en México: ideas, anteojos y cristales
Acosta Silva, Adrián;
Andamios , 2009,
Abstract: this is a brief essay about the relations between facts, ideas, and focusses that have marked various tendencies in mexican political science in the last thirty years. the central argument is that these works have taken shape in the "epistemological communities" that comprise contemporary political science in mexico. starting from a revision of literature produced from 1980 to 2008, we propose a general, preliminary map of the orientations, agendas, problems and methods of investigation that characterize mexican political analysis of recent years.
Mecanismos de acción de los estabilizadores del ánimo
Silva,Hernán;
Revista chilena de neuro-psiquiatría , 2001, DOI: 10.4067/S0717-92272001000300006
Abstract: objective: to analyze the progress made in the understanding of the mechanisms of action of mood stabilizers and their clinical relevance. method: a critical review of the literature with an emphasis on reviews and clinical reports. results: initial mechanisms of action of mood stabilizers are heterogeneous, but their common long-term actions are the most important. lithium and valproate inhibit the glycogen synthase kinase 3 beta and reduce the protein kinase c. the lithium reduction of protein kinase c is mediated by the depletion of inositol. lithium and valproate also affect g proteins, but these effects are not completely understood. these actions induce changes in transcriptional factors, the expression of early genes and the production of neurotrophic factors in the central nervous system. the result is a series of plastic changes in specific neuronal populations. conclusions: knowledge of the mechanisms of action of mood stabilizers, mainly their cellular, genetic and molecular effects, has increased. this knowledge can stimulate the development of new drugs for treating mood disorders
Nuevas perspectivas en la biología de la depresión
Silva,Hernán;
Revista chilena de neuro-psiquiatría , 2002, DOI: 10.4067/S0717-92272002000500002
Abstract: objective. to review the progress in the research about the biological basis of depression and the more recent hypothesis about their etiology. method. a select analysis of recent literature about the biology of depression was made. genetical, neurochemical, inmunological and endocrinological studies were reviewed. results. major progress in the study of biological basis of depression took place in recent years. childhood traumatic events can sensitize stress related neuroendocrine systems. this sensitization can induce enhanced responsiveness to stress in adult life, increasing the vulnerability for the development of anxiety and depressive disorders and predisposing to recurrence. conclusions. a significant development towards an integrative hypothesis about the biological basis of depression was made. this hypothesis would have importance for the development of new antidepressant drugs
