The Effect of Trade and Foreign Direct Investment on Inequality: Do Governance and Macroeconomic Stability Matter?
Angeles-Castro, Gerardo;
Economía mexicana. Nueva época , 2011,
Abstract: through dynamic panel data techniques and applying the estimated household income inequality data-set (galbraith and kum, 2003), this paper is aimed at exploring the effect of economic variables such as trade, foreign direct investment (fdi) and inflation on inequality, under different scenarios of domestic efficiency and over time. trade benefits income distribution, whereas fdi and inflation increase inequality. the expansion of exports and employment based on the primary sector does not provide distributional effects, not even in low income countries. those economies associated with macroeconomic stability and a high governance indicator can mitigate the adverse effect of fdi on income distribution, and enhance the benefits of trade. in the longer run, employment in industry, trade and in particular manufactured exports, can exert more distributional effects, while the adverse effect of fdi and inflation decreases.
The Effect of Trade and Foreign Direct Investment on Inequality: Do Governance and Macroeconomic Stability Matter?
Gerardo Angeles-Castro
Economía Mexicana , 2011,
Abstract: A través de técnicas de panel de datos dinámicos y al aplicar la base de datos de estimadores de desigualdad de ingreso por hogares (Galbraith y Kum, 2003), este artículo explora los efectos de variables económicas tales como comercio, inversión extranjera directa (IED) e inflación sobre la desigualdad, en diferentes escenarios de eficiencia doméstica y a lo largo del tiempo. El comercio beneficia la distribución del ingreso, mientras que la ied y la inflación incrementan la desigualdad. El crecimiento de las exportaciones y el empleo basado en el sector primario no genera efectos distributivos, ni siquiera en países de bajo ingreso. Las economías asociadas con estabilidad macroeconómica y un alto indicador de gobernanza, pueden mitigar el efecto adverso de la IED en la distribución del ingreso e incrementar los beneficios del comercio. En el largo plazo, el empleo industrial, el comercio y en particular las exportaciones manufactureras pueden ejercer más efectos distributivos, mientras que el fecto adverso de la ied y la inflación decrece.
Parasites of Auchenipterus osteomystax (Osteichthyes, Auchenipteridae) from two different environments, Rosana’s reservoir and upper Paraná river floodplain, Brazil = Parasitos de Auchenipterus osteomystax (Osteichthyes-Auchenipteridae) de dois diferentes ambientes, reservatório de Rosana e planície de inunda o do alto rio Paraná, Brasil

Abstract: Surumanha, Auchenipterus osteomystax Miranda-Ribeiro, 1918 is aninsectivorous species that inhabits benthopelagic freshwater environments. In order to know the parasitic fauna and aspects of the host-parasite relationship in surumanhas from Rosana’s hydroelectric reservoir and the upper Paraná river floodplain, 36 specimens fromthe reservoir and 41 specimens from the floodplain were collected, using gill nets. The parasitic fauna of the hosts from the different environments presented low similarity; among ten parasite species present in A. osteomystax, only two were observed in bothenvironments. It was observed significant difference in the prevalence of the metacercariae of Strigeidae in relation to the sex of the hosts from the floodplain, indicating that males are more parasitized. Clinostomum complanatum was the only species that presented significant negative correlation with the relative condition factor (kn) of the host, indicating possiblepathogenicity. A surumanha, Auchenipterus osteomystax Miranda-Ribeiro, 1918 éuma espécie insetívora que habita ambientes bentopelágicos de água doce. Com o objetivo de conhecer a fauna parasitária e os aspectos da rela o parasito-hospedeiro em surumanhas do reservatório da Usina Hidrelétrica de Rosana e da Planície de Inunda o do alto rioParaná, 36 espécimes do reservatório e 41 espécimes da planície de inunda o foram coletados utilizando-se redes de espera. A fauna parasitária deste hospedeiro nos dois ambientes apresentou baixa similaridade, das dez espécies de parasites encontradas em A.osteomystax, somente duas foram observadas nos dois ambientes. Foi observada diferen a significativa na prevalência de parasitismo da metacercária de Strigeidae em rela o do sexo do hospedeiro na planície de inunda o, onde os machos foram mais parasitados.Clinostomum complanatum foi a única espécie que apresentou correla o negativa significativa com o fator de condi o relativo (kn) do hospedeiro, indicando uma possível patogenicidade.
Tumores endocrinos del estómago: Análisis de 13 casos
Angeles-Angeles, Arturo;
Gaceta médica de México , 2005,
Abstract: a thirteen patients with primary endocrine neoplasm of the stomach were studied for 20 years. six patients were male and 7 female with an age range of 33 to 77, mean age 57 years. nine cases corresponded to well differentiated carcinoids and four to neuroendocrine carcinomas. of the former, three were sporadic and six were associated with atrophic gastritis. these two forms of neoplasm showed important differences: those associated with atrophic gastritis had hypergastrinemia, all of the multiple small tumors confined to the corpus and fundus were well differentiated carcinoids associated with intestinal metaplasia and g cell hyperplasia in antrum and ecl cell hyperplasia in corpus and fundus. tumors were clinically benign, with an excellent prognosis. all patients are currently alive with no evidence of neoplasm. in only one of these cases, antiparietal cell antibodies were documented; in three of them, extensive intestinal metaplasia probably due to helicobacter pylori infection was found. in contrast, sporadic carcinoids were large isolated tumors originating in the antrum or corpus. two patients died as a consequence of the neoplasm; all of them were moderately differentiated and in none of the cases we found evidence of endocrine hyperplasia . aii were positive for generic endocrine markers and were focally positive to some of the specific hormone markers. aii four neuroendocrine carcinomas had a clinical course similar to that of gastric adenocarcinomas and were poorly differentiated large tumors. we conclude that gastric carcinoids associated with atrophic gastritis have an excellent prognosis. on the other hand, neuroendocrine carcinomas have a very poor prognosis with fatal outcome of patients. sporadic carcinoids have an intermediate prognosis.

Aeromonas is a Gram-negative bacterium that lives in aquatic habitats. It can be infective in humans. One of its remarkable attributes is the ability of biofilm formation. Many factors are involved in the construction of biofilms as has been described for Pseudomonas, Klebsiella, and Vibrio, among others. The aim of this work was to study the bacterial morphology during the establishment of biofilm through scanning electron microscopy (SEM) and transmission electron microscopy (TEM) with a modified microtiter plate assay and to determine the best conditions for the establishment of Aeromonas caviae Sch3 biolfilm in vitro. We observed several phenotypic changes, including surface appearance, size, presence of extracellular vesicles from 100 to 250 nm in diameter, and flagella. The best conditions for biofilm formation were to grow cultures at 28℃ at pH 6, as determined by the crystal violet assay. This is, to the best of our knowledge, the first study that describes the cell’s biological events involved in the establishment of biofilm formation of Aeromonas caviae Sch3 in vitro.

On the Nature of the Cartesian Stiffness Matrix
Angeles, Jorge;
Ingeniería mecánica, tecnología y desarrollo , 2010,
Abstract: the 6x6 stiffness matrix pertaining to a rigid body mounted on a linearly elastic suspension is revisited here, with the aim of shedding light on its nature via its associated eigenvalue problem. the discussion is based on screw theory and the eigenvalue problem thus arising, in its generalized form. the eigenvalues of the stiffness matrix are shown to occur in real, symmetric pairs, something that has been somehow overlooked in the literature, the product of each eigenvalue by the pitch of its corresponding eigenvector being shown to be non-negative.
