New Rapid Derivative Spectrophotometric and Chromatographic Methods for Assay of Loratadine in Tablets and Syrups

New rapid first-derivative spectrophotometric (UVDS) and a stability-indicating high performance liquid chromatographic (HPLC) methods were developed, validated and successfully applied in the analysis of loratadine (LT) in tablets and syrups. In the UVDS method, 0.1 M HCl was used as solvent. The measurements were made at 312.4 nm in the first order derivative spectra. The HPLC method was carried out on a RP-18 column with a mobile phase composed of methanol-water-tetrahydrofuran (50:30:20, v/v/v). UV detection was made at 247 nm. For HPLC methods the total analysis time was <3min, adequate for routine quality control of tablets and syrups containing loratadine.

Cancer knowledge and skills of interns in Australia and New Zealand in 2001: comparison with 1990, and between course types

Objective: To compare the cancer knowledge and skills of interns in 2001 who graduated from graduate medical program (GMP) courses with those from non-GMP courses, and to compare the cancer knowledge and skills of interns in 2001 with those who completed a similar survey in 1990. Design: Questionnaire survey of recently graduated interns in a random sample of Australian and New Zealand hospitals. The questionnaire was designed to allow direct comparison with the 1990 survey, and was guided by the Australian Cancer Society's Ideal Oncology Curriculum for Medical Schools. Results: 443 interns completed the survey (response rate, 62%; 42 were excluded, leaving 401 surveys for analysis: 118 from GMP courses and 283 from non-GMP courses). Interns from GMP courses felt more competent than those from non-GMP courses at discussing death (P= 0.02), breaking bad news (P= 0.04) and advising on smoking cessation (P= 0.02), but less competent at preparing a patient for a hazardous procedure (P= 0.02). Mote GMP interns would refer a breast cancer patient to a multidisciplinary clinic (83% versus 70%; P= 0.03). Knowledge about cancer risks and prognosis was significantly less in GMP interns, but GMP interns rated their clinical skills, such as taking a Pap smear, higher than non-GMP interns. The GMP and non-GMP groups did not differ in their exposure to cancer patients, but compared with 1990 interns recent graduates had less exposure to patients with cancer. Conclusions: GMP curricula appear to have successfully introduced new course material and new methods of teaching, but have not always succeeded in producing doctors with better knowledge about cancer. Recent graduates have less exposure to cancer patients than those who trained 10 years ago.

Language and trade: the (new) route of portuguese in the 21st century

Globalisation has eliminated frontiers and in the case of Europe helped the crossing of borders and changed forever the concept of social (and I would also say individual) geography: the rest of the world is out there; we can pretend not to see it, but we cannot avoid it. Moreover, Europe is undergoing a serious crisis, also economic, and new markets and business partners are welcome. In this context, cultural bonds like a common language can open new investment paths and give rise to successful stories. In this paper we intend to present an example of how low linguistic distance can lead to good business, even if a) in the internationalization process of the companies’ language is often forgotten as a management element and b) consumers of language products (like User Guides) are also not stimulating investment in language by the companies. Through the results of 2 studies carried out in 2010 and 2011 we will show how a pluricentric language like Portuguese is managed in multinational companies (MC) and Small and medium Enterprises (SMEs). The second study is based on an online survey questioning the effectiveness, efficiency and general quality of User Guides and the reaction of consumers to language. Results show that although playing a role in the internationalization process of companies in the same linguistic space, language is opportunistically used. On the other hand, Portuguese and Brazilian consumers show a very functional perception of the Portuguese language...

Spatial analysis of new cases of leprosy in the State of Espírito Santo, Brazil, between 2004 and 2009

INTRODUCTION: Leprosy in Brazil is a public health issue, and there are many regions in the State of Espírito Santo with high endemic incidence levels of leprosy, characterizing this state as a priority for leprosy programs. The aim of this study was to determine the spatial distribution of coefficients of new cases of leprosy in the State of Espírito Santo, Brazil. METHODS: We conducted a descriptive and ecologic study based on the spatial distribution of leprosy in the State of Espírito Santo between 2004 and 2009. Data were gathered from the available records of the Espírito Santo State Health Secretary. The global and local Bayesian empirical methods were used to produce an estimate of leprosy risk, smoothing the fluctuation effects of the detection coefficients. RESULTS: The study resulted in a coefficient adjustment of new cases in 10 towns that changed their classification, among which, 2 went from low to medium, 4 from medium to high, 3 from high to very high, and 1 from very high to hyper-endemic. An average variation of 1.02, fluctuating between 0 and 12.39 cases/100,000 inhabitants, was found in a comparative calculation between the Local Ebest value and the average coefficient of new leprosy cases in the State of Espírito Santo. CONCLUSIONS: The spatial analysis of leprosy favors the establishment of control strategies with a better cost-benefit relationship since it reveals specific and priority regions, thereby enabling the development of actions that can interfere in the transmission chain.

60,000 years of interactions between Central and Eastern Africa documented by major African mitochondrial haplogroup L2

Mitochondrial DNA (mtDNA) haplogroup L2 originated in Western Africa but is nowadays spread across the entire continent. L2 movements were previously postulated to be related to the Bantu expansion, but L2 expansions eastwards probably occurred much earlier. By reconstructing the phylogeny of L2 (44 new complete sequences) we provide insights on the complex net of within-African migrations in the last 60 thousand years (ka). Results show that lineages in Southern Africa cluster with Western/Central African lineages at a recent time scale, whereas, eastern lineages seem to be substantially more ancient. Three moments of expansion from a Central African source are associated to L2: (1) one migration at 70-50 ka into Eastern or Southern Africa, (2) postglacial movements (15-10 ka) into Eastern Africa; and (3) the southward Bantu Expansion in the last 5 ka. The complementary population and L0a phylogeography analyses indicate no strong evidence of mtDNA gene flow between eastern and southern populations during the later movement, suggesting low admixture between Eastern African populations and the Bantu migrants. This implies that, at least in the early stages, the Bantu expansion was mainly a demic diffusion with little incorporation of local populations.

El problema que abordaremos es la transformación y la toma de decisiones en los procesos de formación y capacitación de las instituciones de seguridad, específicamente, los motivos y fundamentos de los cambios en los planes de estudios, en relación a los contenidos curriculares de los institutos de formación de los profesionales en seguridad. Esto sobre la hipótesis de que las organizaciones educativas policiales y penitenciarias han llevado a cabo transformaciones en su organización y gestión curricular para adecuarse a las nuevas demandas sociales y políticas. El objetivo del presente proyecto es analizar críticamente los contenidos curriculares de los institutos de formación y capacitación de la Policía y Servicio Penitenciario de la Provincia de Córdoba. Abordaremos el análisis de los planes de dichas instituciones en los últimos 10 años, sus modificaciones y criterios utilizados para responder a los nuevos escenarios sociales. Se hará una exploración de la información y la documentación existente en los ámbitos oficiales. Asimismo, la investigación contará con la realización de entrevistas y encuestas a directivos, docentes, alumnos y demás actores claves, con la finalidad de recabar la opinión de los mismos respecto de las transformaciones en la educación policial y penitenciaria. A partir del proyecto de investigación se pretende construir conocimiento acerca de las políticas educativas en el área de seguridad especialmente sobre la formación y capacitación de recursos profesionales específicos, dentro del ámbito local. De tal modo, se pretende aportar elementos teóricos de análisis al modo en que se han instituido la oferta educativa y las transformaciones en los planes de estudios en las instituciones de formación profesional de la seguridad y cómo éstos han sido implementados a la luz de los nuevos escenarios políticos y sociales. Esto nos permitirá aportar al incipiente campo de los estudios sobre la seguridad, específicamente sobre la formación de los profesionales en seguridad, poniendo a diposición de los responsables gubernamentales e institucionales un estudio que explora y sistematiza las transformaciones y fundamentos de la politica de educación en el campo de la seguridad provincial. Este desarrollo investigativo nos permitirá inagurar la actividad de producción de conocimiento dentro del ámbito académico de la Licenciatura en Seguridad de la Universidad Nacional de Villa María a través del presente proyecto que describirá el proceso de formación y capacitación policial y penitenciaria y los cambios que con el transcurso del tiempo se han verificado.

The Paranuclear corpuscles in poikilothermic vertebrates: description of a new species of Pirhemocyton in Iguana iguana of Venezuela, with remarks on the nature of these organisms and their relation to applied parasites

This paper discusses the relations between the genera Toddia and Pirhemocyton, describing certain cytochemical reactions that clarify their nature, and discussing the position of these organisms as being of a parasitic or viral nature. A new species of Pirhemocyton is described form Iguana iguana from Mamo, Marapa (Dto. Federal) of Venezuela; characterized by rectangular globoids with rounded borders. Attempts at experimental infections of other genera of lizerds indicate that the new species, Pirhemocyton iguanae, is specific to the natural host, Iguana iguana. The course of the parasitemia in the lizard is described.

Characterization of Trypanosoma rangeli Strains Isolated in Central and South America: an Overview

Trypanosoma rangeli is a hemoflagelate parasite that infects domestic and sylvatic animals, as well as man, in Central and South America. T. rangeli has an overlapping distribution with T. cruzi, the etiological agent of Chagas disease, sharing several animal reservoirs and triatomine vectors. We have isolated T. rangeli strains in the State of Santa Catarina, in southern Brazil, which dramatically increased the distribution area of this parasite. This brief review summarizes several studies comparing T. rangeli strains isolated in Santa Catarina with others isolated in Colombia, Honduras and Venezuela. The different methods used include indirect immunofluorescence and western blot assays, lectin agglutination, isoenzyme electrophoresis and random amplified polymorphic DNA analysis, triatomine susceptibility, in vitro cell infection assays, and mini-exon gene analysis.
