Programa de higiene bucal, y su impacto en flora bacteriana
NAVARRETE C,AILEEN; BURGOS A,ABED;
Revista chilena de pediatría , 2008, DOI: 10.4067/S0370-41062008000300004
Abstract: objective: to evalúate the presence of supragingival bacterial plaque and porphyromona gingivalis before and after the implementation of an educational program for oral hygiene. methods: 30 scholars were enrolled for 3 months, in order to strenghten their oral hygiene technique and obtain a gingival sulcus bacterial plaque sample monthly. results: porphyromona gingivalis was present in 100% of cases. after 30 days of intervention, oral hygiene reduction in o'leary rate was 21.15%) and bacteria colony forming units in 21.51%o. after 60 days, o'leary índex declined in 29.45%> and bacteria colony forming units in 16.12%o. conclusions: the implementation of an oral hygiene program has a direct impact in the composition of the gingival sulcus bacterial plaque and the decrease of porphyromona gingivalis colony forming units, mainly at 30 days intervention
Programa de higiene bucal, y su impacto en flora bacteriana Oral Hygiene Program and its impact in Bacterial Flora
AILEEN NAVARRETE C,ABED BURGOS A
Revista chilena de pediatría , 2008,
Abstract: Objetivo: Evaluar antes y después de la aplicación de un programa de intervención de higiene bucal la presencia de placa bacteriana supragingival y de Porphyromona gingivalis. Pacientes y Método: A 30 escolares se les realizó mensualmente un muestreo de placa bacteria del surco gingival, índice de OEeary y reforzamiento de la técnica de higiene bucal; durante tres meses. Resultados: La bacteria Porphyromona gingivalis estuvo presente en el 100% de los casos durante todo el período de intervención. A los 30 días de la intervención de higiene bucal la disminución del índice de OEeary fue de un 21,15% y las unidades formadoras de colonias bacterianas en un 21,51%o. Luego a los 60 días el índice de OEeary disminuyó en un 29,45%o y las unidades formadoras de colonias en un 16,12%o. Conclusión: Se concluye que la implementación de un programa de intervención de higiene bucal influye directamente en la composición de la placa bacteriana del surco gingival disminuyendo el número de unidades formadoras de colonias de Porphyromona gingivalis en la medida que la higiene bucal mejora. La mayor disminución fue a los 30 días Objective: To evalúate the presence of supragingival bacterial plaque and Porphyromona gingivalis before and after the implementation of an educational program for oral hygiene. Methods: 30 scholars were enrolled for 3 months, in order to strenghten their oral hygiene technique and obtain a gingival sulcus bacterial plaque sample monthly. Results: Porphyromona gingivalis was present in 100% of cases. After 30 days of intervention, oral hygiene reduction in O'Leary rate was 21.15%) and bacteria colony forming units in 21.51%o.

Estudio cualitativo del uso de plantas medicinales en forma complementaria o alternativa con el consumo de fármacos en la población rural de la ciudad de Bulnes, Región del Bío-Bío, Chile
Abed N. BURGOS,Miguel A. MORALES
Boletín Latinoamericano y del Caribe de Plantas Medicinales y Aromáticas , 2010,
Abstract: En una población rural de la Comuna de Bulnes, VIII región de Chile, fue valorado el consumo de plantas medicinales y fármacos. A través de 168 encuestas fue valorado el consumo de 5 plantas medicinales, su aplicación, las partes mas usadas de las plantas, tipo de consumo, preparación, porcentaje del rango etáreo que consume mayoritariamente plantas medicinales, porcentaje de la población sin y con consumo de fármacos, el porcentaje de las enfermedades presentes en la población en estudio y de los fármacos consumidos. Se obtuvo que las plantas medicinales más consumidas fueron la menta (Mentha piperita), manzanilla (Matricaria recutita), ruda (Ruta graveolens), orégano (Origanum vulgare) y poleo (Mentha pulegium). El consumo de las plantas medicinales fue principalmente de tipo complementario. El uso terapéutico de las plantas medicinales en la población rural de Bulnes, es principalmente de tipo digestivo no relacionándose con las enfermedades de mayor presencia en la población. Dicho uso es probablemente para disminuir las molestias digestivas causadas por el consumo de fármacos. Es necesario realizar mas estudios tendientes a esclarecer este punto de importancia relevante.
Zeno of Elea Shines a New Light on Quantum Weirdness  [PDF]
María Esther Burgos
Journal of Modern Physics (JMP) , 2017, DOI: 10.4236/jmp.2017.88087
Abstract: After a brief reference to the quantum Zeno effect, a quantum Zeno paradox is formulated. Our starting point is the usual version of Time Dependent Perturbation Theory. Although this theory is supposed to account for transitions between stationary states, we are led to conclude that such transitions cannot occur. Paraphrasing Zeno, they are nothing but illusions. Two solutions to the paradox are introduced. The first as a straightforward application of the postulates of Orthodox Quantum Mechanics; the other is derived from a Spontaneous Projection Approach to quantum mechanics previously formulated. Similarities and differences between both solutions are highlighted. A comparison between the two versions of quantum mechanics, supporting their corresponding solutions to the paradox, shines a new light on quantum weirdness. It is shown, in particular, that the solution obtained in the framework of Orthodox Quantum Mechanics is defective.
Unravelling the Quantum Maze  [PDF]
María Esther Burgos
Journal of Modern Physics (JMP) , 2018, DOI: 10.4236/jmp.2018.98106
Abstract: The restoration of philosophical realism as the basis of quantum mechanics is the main aim of the present study. A spontaneous projection approach to quantum theory previously formulated achieved this goal in cases where the Hamiltonian does not depend explicitly on time. After discussing the most relevant flaws of orthodox quantum mechanics, a formulation of the spontaneous projections approach in the general case is introduced. This approach yields experimental predictions which in general coincide with those of the orthodox version and overcomes its main flaws.
Avian Influenza Outbreaks in Southeast Asia Affects Prices, Markets and Trade: A Short Case Study
Sigfrido Burgos,Sergio A. Burgos
International Journal of Poultry Science , 2007,
Abstract: Poultry deaths caused by Highly Pathogenic Avian Influenza (HPAI), loss of consumer confidence, government-mandated culling and export bans are some of the reasons for reduced supply of poultry products to food markets. Reluctance to purchase poultry and its products due to fears of disease contraction has increased demand for other sources of animal protein, which in turn raised prices for other meats. HPAI and its effect on poultry meat consumption disrupt poultry trade patterns.
The Role of Chickens in Vitamin Discoveries
Sigfrido Burgos,Sergio A. Burgos
International Journal of Poultry Science , 2006,
Abstract: Animal models (bioassays) have been of great service to humanity in all sorts of scientific-related advancements. Aves, specifically chickens, played an important role in vitamin discoveries, as it was the first species to be used in 1890`s to study beriberi. We briefly review its 30-year trajectory as an investigational tool in science and medicine.
Influenza A Viruses in Poultry: A Condensed Review
Sigfrido Burgos,Sergio A. Burgos
International Journal of Poultry Science , 2007,
Abstract: Influenza A viruses are comprised of 8 negative-sense RNA segments coding 11 proteins; divided into low and high pathogenicity. They use recombination, deletions and insertions to escape immune system detection. Its epidemiology is defined by interactions between the host, agent and environment. Wild birds are their natural reservoirs; they replicate in the intestinal tract, shed in faeces and transmitted by faecal-oral transmission. They attach to host cells by binding to sialosaccharides on the host cell surface, predominantly to type II pneumocytes, alveolar macrophages and nonciliated cuboidal epithelial cells in terminal bronchioles. High mortality rates of 61% in humans and 90-100% in poultry are seen.
HPAI H5N1 in Europe 2007: Poultry and Wild Birds
Sigfrido Burgos,Sergio A. Burgos
International Journal of Poultry Science , 2008,
Abstract: There were 308 HPAI cases in wild birds, most of them in Germany and 13 HPAI outbreaks in poultry, with clear spatial and temporal infectious patterns. Grebes, swans, ducks, chickens and turkeys got most frequently infected. The United Kingdom, Czech Republic and Germany hosted many viral incursions.
Environmental Approaches to Poultry Feed Formulation and Management
Sigfrido Burgos,Sergio A. Burgos
International Journal of Poultry Science , 2006,
Abstract: Increasing environmental pressures on the poultry industry challenge the status quo of ecological stewardship. Faced with this critical oversight, nutritionists, poultry and soil scientists, and pollution specialists are creatively proposing bundled strategies dealing with various practices related to dietary manipulation, poultry litter management and feed additive utilization to palliate the potential environmental impact of poultry production. Their implementation has proved beneficial to both, the poultry industry and the environment.
