Laboratory assessment of the hypertensive individual. Value of the main guidelines for high blood pressure

OBJECTIVE: To determine if abnormal laboratory findings are more common in individuals with hypertension and in those with other risk factors, such as obesity, smoking and alcohol ingestion. METHODS: A study was carried out in the general outpatient clinics of a university hospital (145 individuals without previous diagnosis of hypertension) and the following variables were assessed: high blood pressure (as defined by the VI Joint National Committee on Prevention, Detection and Treatment of High Blood Pressure - VI JNC), obesity [calculated using body mass index (BMI)], tobacco use, and alcoholic ingestion. The laboratory examinations consisted of the following tests: hemogram, glycemia, uric acid, potassium, total/HDL-fraction cholesterol, triglycerides, calcium and creatinine. RESULTS: High blood pressure was not associated with a higher number of abnormal laboratory tests. Hypertensive individuals with a BMI > or = 25kg/m² or normotensive obese individuals, however, had a higher frequency of diabetes (12X), hypertriglyceridemia (3X), and hypercholesterolemia (2X), as compared with hypertensive individuals with BMI <25kg/m² and preobese/normal weight normotensive individuals. CONCLUSION: High blood pressure is not associated with a higher frequency of abnormal laboratory tests. The association of high blood pressure and obesity, however, increases the detection of diabetes and dyslipidemias.

Diseño y Desarrollo de Nuevas Entidades Químicas de Interés Farmacéutico. Design and Development of New Chemical Entities of Pharmaceutical Interest.

Este proyecto de investigación se basa fundamentalmente en diversas actividades concernientes a la investigación y desarrollo de nuevos fármacos. Estos estudios se llevan a cabo sobre nuevos derivados de las siguientes drogas líderes utilizadas en el tratamiento del SIDA: zidovudina (AZT), lamivudina (3TC), didanosina (ddI) y un tipo particular de Inhibidores No Nucleosídicos de la Transcriptasa Reversa (INNTR) conocidos como "diarilpirimidinas" (DAPYs). Se plantean para el presente proyecto los siguientes objetivos específicos:1. Diseño racional y síntesis de nuevos compuestos,2. Evaluación de actividades biológicas y citotoxicidad,3. Estudio de las propiedades fisicoquímicas de interés biológico y farmacéutico,4. Estudios farmacocinéticos y biofarmacéuticos.De esta manera, se ha considerado un estudio integrador, tendiente a conocer y entender el posible comportamiento en el organismo de nuevas entidades químicas de interés farmacéutico (NEQF). Así, nuestra hipótesis de trabajo se sustenta en que la variación de las propiedades fisicoquímicas y farmacocinéticas de las drogas actualmente en uso o en etapas de experimentación, podrá incidir favorablemente en la farmacoterapia del SIDA.Cabe destacar que la aplicación de diversos métodos computacionales, constituye una herramienta muy importante que se utilizada para cada uno de los objetivos planteados ya que brinda información complementaria y una ayuda invalorable para el diseño racional de drogas.Así, se diseñarán, prepararán y caracterizarán NEQF, estudiando en detalle sus propiedades moleculares. Se espera que la información generada represente una contribución para el desarrollo de nuevas opciones terapéuticas efectivas frente al agente causativo del SIDA, enfermedad para la cuál la opción de una terapia efectiva está lejos de ser la ideal.Como el proyecto se desarrolla dentro de un ámbito académico, las actividades previstas permitirán a los becarios y tesistas: 1) ampliar y profundizar los conocimientos teóricos relacionados con los temas de estudio; 2) desarrollar su capacidad creativa; 3) posibilitar el trabajo multidisciplinario. Es decir, se formarán recursos humanos altamente capacitados en el diseño y desarrollo de NEQF, finalizando las tesis doctorales en ejecución e incorporando nuevos jóvenes farmacéuticos.A partir de los resultados que se logren en el campo científico y académico, se espera contribuir a la promoción del conocimiento en el área del diseño y del desarrollo de Compuestos Farmacéuticos Activos. Es de nuestro especial interés que los resultados lleven a un posicionamiento del grupo en el área de la Química Medicinal, de la Bioorgánica y de la Biofarmacia.Con relación a la importancia del proyecto, cabe destacar que la Química Medicinal es una disciplina poco desarrollada en nuestro país, por lo tanto contribuirá no sólo a la generación de conocimiento en el área, sino también a la formación de recursos humanos. Cabe destacar la participación de jóvenes farmacéuticos que son los beneficiarios de dicho proceso de formación. Por otra parte, el desarrollo de NEQF conlleva en sí mismo un impacto social y económico importante, y redunda en beneficio de la salud de la población. Teniendo en cuenta la realidad actual, y considerando que la solución final para el tratamiento del SIDA aún no se ha alcanzado, optimizar la actividad/efectividad de fármacos conocidos y estudiar nuevas moléculas que actúen sobre diversas dianas biológicas constituye una esperanza para el tratamiento eficaz de esta enfermedad. Finalmente, teniendo en cuenta que la finalidad del proyecto es desarrollar nuevos agentes anti VIH con potencial aplicación clínica, es de esperar poder interaccionar con la industria farmacéutica y transferir los resultados a la misma.

Procesos adaptativos y dimensiones del comportamiento biosocial en cazadores recolectores del SW de la provincia de La Pampa.

Resumen del proyecto: Este resumen se incluirá en la base de datos de la Biblioteca Digital del Ministerio, por lo que se debe elaborar el mismo sobre la base de la siguiente estructura y completar todos los campos que se indican a continuación: identificación y caracterización del problema objeto del estudio, hipótesis, planteo de objetivos, materiales y métodos a utilizar, resultados esperados, importancia del proyecto (extensión del campo 4000 caracteres). Proyecto diseñado para aportar al conocimiento de los procesos adaptativos y la dinámica biosocial de las sociedades del pasado prehistórico argentino. Propone analizar y evaluar el potencial documental de los restos bioarqueológicos con fehaciente asociación contextual para posibilitar la realización de inferencias sobre procesos biosociales de naturaleza adaptativa o no adaptativa. Está centrado en el análisis osteológico y biocultural de materiales esqueletales (aproximadamente cien individuos) correspondientes a poblaciones aborígenes prehistóricas del actual territorio de la provincia de La Pampa (Médano Petroquímica, Departamento Puelén). Entre otros muchos aspectos, la importancia de estos materiales reside en que son asignables a sociedades con economía cazadora-recolectora y cuya cronología corresponde al Holoceno tardío final (Entierros datados en 393 ± 41 cal AP AMS.), una época particularmente interesante por la dinámica sucesión de eventos socioculturales y poblacionales que la caracterizan. La evidencia recuperada da cuenta de prácticas funerarias complejas que consisten en la realización de enterratorios colectivos, indirectos, secundarios, y presencia de eventos de violencia y/o tensión social. Los métodos y técnicas consisten en la descripción e identificación basados en observación y registro de marcadores esqueléticos conforme a prácticas estándares de nuestro laboratorio: Planillas de observación y registro durante excavaciones de la Archaeological Summer Field School (ASFS) de la Universidad de Chicago y planillas de los “Standards” de Buikstra y Ubelaker, modificadas y adaptadas por nuestro grupo de trabajo, entre otros). Los datos obtenidos serán empleados para graficación (estadística descriptiva) y también se realizará sobre ellos análisis multivariados y estadística no paramétrica (etapa inferencial). Se tendrán en cuenta aspectos descriptivos y analíticos vinculados con el reconocimiento de la edad y el sexo, hábitos dietarios (marcadores morfológicos y químicos de hueso y dientes), economía de subsistencia, patrones de diferenciación social, exploración de eventuales relaciones de parentesco, roles vinculados con el sexo, el uso del cuerpo, dieta, salud y enfermedad, en relación con la economía de subsistencia, etc. (Buikstra y Beck 2006, Larsen, 1997, White y Folkens 2000). Dado la naturaleza y complejidad de los hallazgos, caracterizados por la conformación de entierros colectivos secundarios e indirectos, un capítulo de interés lo constituye el análisis de las dimensiones sociales del comportamiento mortuorio y la discusión de los indicadores de violencia y/o tensión social asociados a los hallazgos (O´Shea 1984, Rakita et al. 2005, entre otros). Dado el hecho de que se cuenta con la disponibilidad de materiales adecuados para este tipo de estudios, la información relevante y los datos a analizar serán obtenidos mediante la aplicación de métodos y técnicas bioarqueológicas específicas antes mencionados, con la finalidad de observar y discutir tendencias y proponer modelos de interpretación sujetos a ulterior validación, particularmente toda vez que se cuente con una mayor representación numérica y casuística tanto a nivel de individuos como de sitios bioarqueológicos excavados. El proyecto se enmarca en la firma de un Convenio Específico de Trabajo entre la UNRC y el Gobierno de La Pampa. Palabras clave: Ingrese hasta 5 palabras clave, distintas de las utilizadas en el título del proyecto y que describan la naturaleza del objeto de estudio. bioarqueología economía cazadora-recolectora adaptación biosocial comportamiento mortuorio Violencia y tensión social. Abstract: Resumen del proyecto en inglés (extensión del campo 2000 caracteres). This project has been designed to improve the knoledge on adaptive processes and biosocial dynamics among aborigine past societies in Argentina. This research is focused on the analysis and evaluation of documentary potential of bioarchaeological skeletal remains with reliable contextual associations. It is specifically centered in the osteological as well as cultural analysis of more than one hundred skeletons from native prehistoric populations from a prehistoric collective burial site in La Pampa province. (Médano Petroquímica, Departamento Puelén). Among other aspects, the importance of the materials to be analyzed lies in the fact that they correspond to a subsistence economy based on hunting and gathering, and have been chronologically assigned to Late Holocene times (burials dated 393 ± 41 cal AP AMS), a period denoting particular interest due to the dynamic succession of sociocultural events that characterized it. Evidence so far recovered accounts for complex funerary practices consisting of indirect, secondary collective burials, as well as the presence of events of violence and/o social tension. Methods and techniques consist in the description and identification based on the observation, and recording of skeletal markers, according to laboratory as well as field work standards: The University of Chicago Archaeological Summer Field School (ASFS) forms, and the “Standards” forms from Buikstra y Ubelaker (1994), modified and adapted by our research team, among others. Data obtained shall be used for graphic (descriptive statistics) as well as multivariate analyses and non parametric statistics (inferential stage). Descriptive as well as analytical aspects such as those related to age and sex determination, feeding habits (morphological as well as chemical markers of bones and teeth), subsistence economy, patterns of social differentiation, kinship patterns, sex-linked roles, body use, diet, health and disease, all of them in close relationship with the hunter-gatherer subsistence economy (Buikstra y Beck 2006, Larsen, 1997, White y Folkens 2000). Given the nature and complexity of the burial disposals, characterized by complex collective burials, a core chapter of our interest is that of social dimensions of mortuary behavior as well as the discussion and interpretation of markers of violence and/or social tension. Given the amount of evidence gathered so far, relevant information as well as data to be analyzed will be obtained by specific bioarchaeological methods and techniques, trying to observe and discuss possible trends as well as to formulate interpretive models to be verified or rejected with the arrival of new, reliable data both at individual level as well as at the archaeological sites to be excavated. This project has been particularly considered in a bilateral agreement between UNRC and the Government of La Pampa Province.

The importance of this project is aimed at obtaining new electrochemical data for the indicated substrates and knowledge on the application of modified electrodes in preparation of biosensors and in the development of alternative techniques for the determination of the above-mentioned analytes.

An assessment of biological and population parameters of the Common whelk, Buccinum undatum (L.) in the region of the North West Irish whelk fishery

The Common whelk, Buccinum undatum (L.) is a conspicuous benthic scavenger in Irish waters, and is a valuable fisheries resource in South East Ireland. B. undatum is fished in many parts of its range, and previous studies have shown that certain life history parameters, which vary with location, make this species vulnerable to overexploitation. This makes research into each exploited stock essential to ensure sustainable fisheries management of the species. In 2003, interest in B. undatum as a complementary species in the inshore fishery east of the Inishowen Peninsula, North West Ireland, initiated investigation into fisheries related biological and population aspects of the species in this region. The current study presents estimates of spatial variation and density of the stock, size at age and growth rates, size and age at onset of sexual maturity, and timing of reproductive events in the region of the North West Irish whelk fishery for the period of June 2003 to May 2004. Analysis of variance of the total shell length of whelk landings to the fishery was conducted over spatial scales of fishing pot, fishing string and landings to vessels. Landings varied significantly in shell length at the spatial scale at which whelks are attracted to baited pots, but did not vary significantly over larger spatial scales. Depletion estimates of stock density from fisheries derived Catch per Unit Effort data and a mark re-capture experiment estimate 0.134 - 0.227 whelks per m2. Two independent methods of age determination found similar growth logistics functions for B. undatum.Modal analysis of length frequency distribution of landings to the fishery estimated symptotic length, Leo = 151.64 mm and Brody growth coefficient, K = 0.04. Analysis of the striae in individual opercula, where each stria was found to represent annual growth, estimated Loo = 137.73 mm and K = 0.12. Common whelks in the region of the North West Irish whelk fishery grow slowly and are long-lived, with 19 opercula striae recorded in one individual. Onset of sexual maturity is late, and no sex-specific differences in size or age at maturity were determined in the present study. Males were found to achieve sexual maturity at 83.30 ± 10.77 mm, and 8.9 - 11.1 years of age, and females at 82.62 ± 10.68 mm and 8.8 to 11.1 years of age. Systematic observations of reproductive events, including histological changes to the female ovary and male testis, and changes in the size and mass of body components, suggest that breeding occurred between the autumn and winter months of October and December 2003. Biological aspects of B. undatum in the study region are compared with previous studies from other regions, and discussed in relation to sustainable management of the fishery.

Uma raça cromossômica natural de Tityus bahiensis (Scorpiones-Buthidae)

A natural chromosomal race of Tityus babiensis (Scorpiones Buthidae) is described in the present paper. Five males and seven females received from St. Joaquim, State of S. Paulo, gave the following interesting results: All the spermatogonia of the five males were provided with 9 chromosomes of different sizes. All primary spermatocytes showed at metaphase one independent bivalent of normal shape and a complex group formed by 7 chromosomes which have exchanged parts. Some of the chromosomes associated in the complex group, to Judge by their behavior, were composed of fragments of three different chromosomes, being thus paired with three other members of the compound group. The manner in which all the 7 components of the group have paired with each other showed to be very constant. They gave always origin to a double-cross configuration, the longst branch of which being formed by a long chromosome paired with two components of the group and with a third chromosome that did not belong to the group. The chromosomes of the independent bivalent separate regularly, going to different poles. From the 7 elements of the compound group, 4 go to one pole and 3 to the opposite one. Consequently, secondary spermatocytes with 4 and 5 chromosomes are produced. The females, so far as it can be inferred from the study of the follicular cells of the ovariuterus, have 10 chromosomes. These females are, therefore, considered as being monogametic, that is, as producing eggs with 5 chromosomes. A sex-determining mechanism arose in this manner, the spermatozoa with 5 chromosomes giving origin to females and those with 4 to males. The fact that the sex chromosome is one of the elements taking part in the formation of the group, seems highly interesting to the author. Tetraploid cysts have been occasionally found in the testis. In one individual the chromosomes of the tetraploid primary spermatocytes behaved as expected, forming a group of 14 elements, and two independent pairs or a tetravalent group In another individual, the chromosomes of the tetraploid cells have formed two independent groups of 7, and two independent pairs, as if both chromosomal sets were by their turn entirely independent frcm one another. This fact is certainly not devoid of special interest. The males as well as the females studied in this paper differed in nothing from the typical members of the species. The unique differential character of the new race is found in the umber and behavior of its chromosomes. It is highly remarkable that the occurrences which have transformed the 6 chromosomes normally present in the species into a new set of 9 elements, 7 of which have been profoun- dly altered in their structure, do not show any influence on the morphology of the organism. This fact, together with those found in the salivary-chromosomes races of Drosophila and Sciara. compromises strongly the genetical concept of position effects.

A internação forçada do toxicodependente : uma perspectiva brasileira, sob um contraste lusitano, acerca da proporcionalidade da medida em face da dignidade da pessoa humana

A presente dissertação busca abordar a questão da restrição ao direito fundamental de liberdade da pessoa toxicodependente no Brasil, consistente, precisamente, na internação forçada para o tratamento de sua saúde e/ou para a segurança pública, sob o olhar do princípio constitucional da dignidade da pessoa humana em suas dimensões positiva, que exige uma obrigação de fazer por parte do Estado, e negativa, que cobra deste uma postura omissiva de proteção, em torno de um mesmo indivíduo; sem se olvidar do interesse público na execução da medida. Para tanto, ao longo do trabalho, a legislação brasileira atinente ao tema é posta em comparação com a sua correspondente portuguesa e, à luz, basicamente, das doutrinas desses países, são examinados direitos afetos à liberdade individual e ao direito social à saúde, sob a costura do apontado princípio estruturante das respectivas Constituições, de modo a permitir a visualização do amparo da medida restritiva no texto maior brasileiro e, ao final, uma análise crítica à ponderação de bens (direitos) realizada pelo legislador ordinário, com possíveis soluções para a sua aplicação em concreto, quando da análise da proporcionalidade da intervenção da liberdade pelo Poder Judiciário.
