Revista de Obstetricia y Ginecología de Venezuela , 2004,
Abstract: Objetivo: Comparar los gérmenes aislados en el tracto genital inferior de pacientes con el virus de la inmunodeficiencia humana positivas con las negativas. Método: Estudio prospectivo, comparativo, analítico y descriptivo de 106 pacientes, 53 VIH positivo y 53 negativas. Ambiente: Servicio 4. Departamento Obstétrico del Servicio Autónomo Hospital Universitario de Maracaibo, "Maternidad Dr. Armando Castillo Plaza". Maracaibo, Estado Zulia. Resultados: De las 106 pacientes estudiadas, 53 eran virus; positivo 35 de ellas (66,03%) estaban embarazadas y 18 (33,96%) no. Las 53 pacientes negativas estaban embarazadas. El mayor grupo de virus positivas, 40 casos (75,47%) tenían edades comprendidas entre 21 y 35 a os y de las negativas, 36 casos (67,92%) entre 21 y 30 a os. El número de parejas entre las VIH positivo fue de 3 (37,73%), y en las negativas fue de 1 (41%). Los resultados de los cultivos mostraron 26,11% de flora vaginal normal en ambos grupos. El principal agente infeccioso presente en la embarazada fue la Candida albicans con 20,75% en los dos grupos estudiados. Conclusiones: Es necesario realizar cultivo en las pacientes con virus de la inmunodeficiencia humana como negativas, para utilizar el tratamiento adecuado, evitar la destrucción de la barrera mucosa y en especial cuando ocurren asociaciones entre gérmenes, y en el caso de las VIH positivas disminuir la capacidad de la mucosa vaginal como reservorio y sitio de replicación del virus.

Abstract: Introduction. Intestinal parasitic infections, especially due to helminths, increase anemia in pregnant women. The results of this are low pregnancy weight gain and IUGR, followed by LBW, with its associated greater risks of infection and higher perinatal mortality rates. For these reasons, in the setting of no large previous studies in Venezuela about this problem, a national multicentric study was conducted. Methods. Pregnant women from nine states were studied, a prenatal evaluation with a coproparasitological study. Univariated and multivariated analyses were made to determine risk factors for intestinal parasitosis and related anemia. Results. During 19 months, 1038 pregnant women were included and evaluated. Intestinal parasitosis was evidenced in 73.9%: A lumbricoides 57.0%, T trichiura 36.0%, G lamblia 14.1%, E hystolitica 12.0%, N americanus 8.1%, E vermicularis 6.3%, S stercoralis 3.3%. Relative risk for anemia in those women with intestinal parasitosis was 2.56 (P<.01). Discussion. Intestinal parasitoses could be associated with conditions for development of anemia at pregnancy. These features reflect the need of routine coproparasitological study among pregnant women in rural and endemic zones for intestinal parasites. Further therapeutic and prophylactic protocols are needed. Additional research on pregnant intestinal parasitic infection impact on newborn health is also considered.
Pertinencia de la noción de capacidades societales de innovación en las corporaciones venezolanas*
Colina,Belinda;
Revista de Ciencias Sociales , 2006,
Abstract: the objective of this research is to analyze the pertinence of the notion of societal capacities for innovation by venezuelan corporations. the research is analytical and its design is non-experimental. the technique of documentary observation was used. the results determined that corporations in general do not do specify their responsibility in creating and facilitating conditions for the construction of societal capacities for innovation of traditional and nontraditional economic social actors, and also show little responsibility in the diffusion of innovations in venezuelan corporations which must be due to the limitations and difficulties in industrial and business management formation with industrial vocation on the part of venezuelan business men. the most important conclusion is that the notion of societal capacities comprehended by most venezuelan corporations is incomprehensible when taking into account of innovative processes in venezuelan corporations.
Evidence of structural genomic region recombination in Hepatitis C virus
Juan Cristina, Rodney Colina
Virology Journal , 2006, DOI: 10.1186/1743-422x-3-53
Abstract: Putative recombinant sequences were identified with the use of SimPlot program. Recombination events were confirmed by bootscaning, using putative recombinant sequence as a query.Two crossing over events were identified in the E1/E2 structural region of an intra-typic (1a/1c) recombinant strain.Only one of 89 full-length strains studied resulted to be a recombinant HCV strain, revealing that homologous recombination does not play an extensive roll in HCV evolution. Nevertheless, this mechanism can not be denied as a source for generating genetic diversity in natural populations of HCV, since a new intra-typic recombinant strain was found. Moreover, the recombination break-points were found in the structural region of the HCV genome.Hepatitis C virus (HCV) is estimated to infect 170 million people worldwide and creates a huge disease burden from chronic, progressive liver disease [1]. HCV has become a major cause of liver cancer and one of the commonest indications of liver transplantation [2,3]. HCV has been classified in the family Flaviviridae, although it differs from other members of the family in many details of its genome organization from the original (vector-borne) members of the family [1]. Like most RNA viruses, HCV circulates in vivo as a complex population of different but closely related viral variants, commonly referred to as a quasispecies [4-7].HCV is an enveloped virus with an RNA genome of approximately 9400 bp in length. Most of the genome forms a single open reading frame (ORF) that encodes three structural (core, E1, E2) and seven non-structural (p7, NS2-NS5B) proteins. Short unstranslated regions at each end of the genome (5'NCR and 3'NCR) are required for replication of the genome. This process also requires a cis-acting replication element in the coding sequence of NS5B recently described [8]. Translation of the single ORF is dependent on an internal ribosomal entry site (IRES) in the 5'NCR, which interacts directly with the 40S ribosomal sub
Obtención y evaluación de arroz integral de cocción rápida
Colina,Jhoana; Guerra,Marisa;
Interciencia , 2009,
Abstract: the cereals of highest consumption in venezuela are corn, wheat and rice, the later having a higher yield and a better nutritional value that decreases with processing. brown rice is rich in vitamins and minerals and its consumption is low, due to its long cooking time (45-60min). in recent years there has been a boom in the development of healthy products of fast preparation. the objective was to obtain and evaluate a quick-cooking brown rice. a three-stage process was used: 1) soaking. the effects of dissolution, temperature and time on the water absorption, volume increase and humidity were evaluated. 2) cooking. the effects of temperature and time on water absorption, volume increase and gelatinization were studied, and the best treatment was compared with heating in an autoclave. 3) drying. two temperatures were used and the rehydration capacity was measured. the composition and mineral content of the raw brown rice and the quick cooking brown rice were determined. a quick cooking (25min) brown rice was obtained which maintained its nutritional characteristics in terms of protein, fat and minerals.
Cogestión de empresas y transformación del sistema económico en Venezuela: Algunas reflexiones
Vera Colina,Mary A;
Gaceta Laboral , 2006,
Abstract: in the face of new governmental policies related to business co-management in venezuela, this paper proposes some reflections related to the application of mechanisms for popular participation in the economic sphere, and in particular co-management and its possible effect in the transformation of the venezuelan economic system. documents related to these mechanisms are reviewed, and their economic implications are discussed. as a conclusion, it is proposed that the transformation in economic systems will depend greatly on the transparency of the objectives, on the combination of diverse public policies in a national economic project, and on the clarity and permanence of the rules applied by the state. we do not visualize sufficient reasons in the application of models of co-management and participation which would imply a radical change in the present economic system in venezuela.

Redes de innovación socio productivas en el desarrollo endógeno: caso Las Peonías
Colina,; Rojas,Thaís;
Revista de Ciencias Sociales , 2008,
Abstract: the objectives of this study are to determine favorable conditions for establishing socio-productive innovation networks (spin), as well as proposing their creation in the community of peonías, in the idelfonso vázquez parish, municipality of maracaibo, zulia. the methodology was qualitative, exploratory, descriptive and documentary, based on a case study; it is also a propositional study. documents about the aforementioned community were reviewed, official organisms were visited and a field investigation was conducted consisting of interviews with community leaders, inhabitants of the zone and representatives of some organisms. results indicated that joint capital in peonías is in an embryonic state of development. conclusions are: 1) the constitution of spin in peonías, within the endogenous development framework, must be sustained with proximity networks in the first instance, and secondly, with long distance networks. 2) it is important to fortify existing capacities and create new capacities in this community in order to forward endogenous development for the well-being and autonomy of this social group, which constitutes a natural, population, economic and cultural reservoir that has not been used and which has broad local, regional and national possibilities.
Cogestión de empresas y transformación del sistema económico en Venezuela: Algunas reflexiones Firm Co-Management and Changes in the Venezuelan Economic System: Some Reflections
Mary A Vera Colina
Gaceta Laboral , 2006,
Abstract: Ante la novedad de la política gubernamental relacionada con los modelos de cogestión de empresas, se propone un conjunto de reflexiones con respecto a la aplicación de mecanismos de participación popular en la esfera económica, particularmente sobre la cogestión, y su posible incidencia sobre la transformación del sistema económico venezolano. Para ello se revisan documentos que respaldan el empleo de esta figura, y se comentan sus implicaciones económicas. A manera de conclusión, se plantea que la transformación del sistema económico dependerá en buena parte de la transparencia de los objetivos, de la integración de las diferentes políticas públicas en un proyecto económico nacional, de la claridad y permanencia que tengan las reglas aplicadas por el Estado. No se visualiza en la aplicación de los modelos de cogestión y de participación, suficientes razones que impliquen un cambio radical en el sistema económico imperante en el país. In the face of new governmental policies related to business co-management in Venezuela, this paper proposes some reflections related to the application of mechanisms for popular participation in the economic sphere, and in particular co-management and its possible effect in the transformation of the Venezuelan economic system. Documents related to these mechanisms are reviewed, and their economic implications are discussed. As a conclusion, it is proposed that the transformation in economic systems will depend greatly on the transparency of the objectives, on the combination of diverse public policies in a national economic project, and on the clarity and permanence of the rules applied by the State. We do not visualize sufficient reasons in the application of models of co-management and participation which would imply a radical change in the present economic system in Venezuela.
