Abstract: Esta investigación objetiva describir al perfil de las embarazadas en la 13a Coordenaduría Regional de Salud (2003) en las dimensiones del acompa amiento pre-natal, inmunizaciones y gestantes con menos de 20 a os. El estudio es de tipo descriptivo-exploratorio. De entre las mujeres embarazadas menores de 20 a os, se destacan las ciudades de Candelária (53,3%), Herveiras (50,0%), Venancio Aires (30%) y Santa Cruz do Sul (28,9%). En cuanto al porcentaje sobre la realización de las inmunizaciones, excepto Santa Cruz do Sul (74,7%) y Venancio Aires (72,5%), los otros fueron superiores al 85%. Santa Cruz do Sul y Venancio Aires también, presentaron los más bajos porcentajes pare el pre natal en el 1° trimestre, excepto Mato Leit o y Herveiras (94,1% y 94,6%, respectivamente), los otros municipios presentaron porcentajes abajo del 77%. Estos datos sugieren acciones más eficaces en el campo de la salud preventiva, lo cual podría atenuar los niveles elevados de gestantes menores de 20 a os en esta región.

Arquivos Brasileiros de Cardiologia , 2010, DOI: 10.1590/S0066-782X2010005000046
Abstract: background: during childhood and adolescence, physical inactivity, excess weight, and poor nutrition are risk factors for chronic diseases, especially obesity, hypertension, and diabetes mellitus. early intervention can prevent the development of these complications. objective: to determine the presence of cardiovascular risk (obesity and hypertension) in schoolchildren and its potential interactions with cardio-respiratory fitness. methods: this was a cross-sectional study conducted in a stratified cluster sample of 1,666 schoolchildren, aged between 7 and 17 years, 873 (52.4%) of them male and 793 (47.6%) of them female. the following variables were evaluated: systolic blood pressure (sbp), diastolic blood pressure (dbp), body mass index (bmi), body fat percentage (bf %), and cardio-respiratory fitness. sbp and dbp were correlated with waist circumference (wc), waist-hip ratio (whr), sum of skin folds (σsf), and cardio-respiratory fitness. results: a bmi assessment of the students showed that 26.7% of them were overweight or obese, and 35.9% had body fat percentage over moderately high. as to blood pressure, we found that 13.9% and 12.1% of the students were borderline or hypertensive, for sbp and dbp, respectively. there was an association among hypertension, obesity, and cardio-respiratory fitness. there was a significant correlation of sbp and dbp with all variables, and also a weak to moderate correlation with age, weight, height, bmi, and waist circumference. conclusion: the presence of hypertension associated with obesity and its effects on cardio-respiratory fitness stress the importance of recommending, since childhood, a more active and healthy lifestyle.
Nuclear Mitochondrial DNA Activates Replication in Saccharomyces cerevisiae

PLOS ONE , 2012, DOI: 10.1371/journal.pone.0017235
Abstract: The nuclear genome of eukaryotes is colonized by DNA fragments of mitochondrial origin, called NUMTs. These insertions have been associated with a variety of germ-line diseases in humans. The significance of this uptake of potentially dangerous sequences into the nuclear genome is unclear. Here we provide functional evidence that sequences of mitochondrial origin promote nuclear DNA replication in Saccharomyces cerevisiae. We show that NUMTs are rich in key autonomously replicating sequence (ARS) consensus motifs, whose mutation results in the reduction or loss of DNA replication activity. Furthermore, 2D-gel analysis of the mrc1 mutant exposed to hydroxyurea shows that several NUMTs function as late chromosomal origins. We also show that NUMTs located close to or within ARS provide key sequence elements for replication. Thus NUMTs can act as independent origins, when inserted in an appropriate genomic context or affect the efficiency of pre-existing origins. These findings show that migratory mitochondrial DNAs can impact on the replication of the nuclear region they are inserted in.

Abstract: the risk of developing cardiovascular disease (cvd) is related to lifestyle (e.g. diet, physical activity and smoking) as well as to genetic factors. this study aimed at evaluating the association between cvd risk factors and dna damage levels in children and adolescents. anthropometry, diet and serum cvd risk factors were evaluated by standard procedures. dna damage levels were accessed by the comet assay (single cell gel electrophoresis; scge) and cytokinesis-blocked micronucleus (cbmn) assays in leukocytes. a total of 34 children and adolescents selected from a population sample were divided into three groups according to their level of cvd risk. moderate and high cvd risk subjects showed significantly higher body fat and serum cvd risk markers than low risk subjects (p<0.05). high risk subjects also showed a significant increase in dna damage, which was higher than that provided by low and moderate risk subjects according to scge, but not according to the cbmn assay. vitamin c intake was inversely correlated with dna damage by scge, and micronucleus (mn) was inversely correlated with folate intake. the present results indicate an increase in dna damage that may be a consequence of oxidative stress in young individuals with risk factors for cvd, indicating that the dna damage level can aid in evaluating the risk of cvd.

M. E. Burgos
Journal of Modern Physics (JMP) , 2010, DOI: 10.4236/jmp.2010.12019
Abstract: In this paper, it showed that the orthodox version of quantum mechanics contradicts the idea that conservation laws are valid in individual processes of measurement.

M. E. Burgos
Journal of Modern Physics (JMP) , 2015, DOI: 10.4236/jmp.2015.611168
Abstract: We make a brief historical revision of action-at-a-distance in quantum mechanics. Non-locality has been mostly related to systems of two particles in an entangled state. We show that this effect is also apparent in some experiments with individual particles. An easily performed experiment in this regard is introduced.
Success and Incoherence of Orthodox Quantum Mechanics  [PDF]
M. E. Burgos
Journal of Modern Physics (JMP) , 2016, DOI: 10.4236/jmp.2016.712132
Abstract: Orthodox quantum mechanics is a highly successful theory despite its serious conceptual flaws. It renounces realism, implies a kind of action-at-a-distance and is incompatible with determinism. Orthodox quantum mechanics states that Schrödinger’s equation (a deterministic law) governs spontaneous processes while measurement processes are ruled by probability laws. It is well established that time dependent perturbation theory must be used for solving problems involving time. In order to account for spontaneous processes, this last theory makes use of laws valid only when measurements are performed. This incoherence seems absent from the literature.
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.
