The Poisson Distribution Is Applied to Improve the Estimation of Individual Cell and Micropopulation Lag Phases  [PDF]
Juan x Juan Aguirre, Carmen Bravo, Juan A. Ordó?ez, Gonzalo García de Fernando
Advances in Microbiology (AiM) , 2012, DOI: 10.4236/aim.2012.22020
Abstract: Many articles dealing with individual cell lag phase determination assume that growth, when observed, comes from one cell. This assumption is not in agreement with the Poisson distribution, which uses the probability of growth in a sample to predict how many samples contain one, two, or some other number of cells. This article analyses and compares different approaches to improve the accuracy of lag phase estimation of individual cells and micropopulations. It argues that if the highest initial load, as predicted by the Poisson distribution, is assigned to the sample with the shortest lag phase, the second highest to the sample with the second shortest lag phase and so on, the resulting lag phase distributions would be more accurate. This study also proposes the use of a robust test, permutation test, to compare lag phase distributions obtained in different situations.
An Approach for Micropropagation of Blueberry (Vaccinium corymbosum L.) Plants Mediated by Temporary Immersion Bioreactors (TIBs)  [PDF]
Ariel D. Arencibia, Carolina Vergara, Karla Quiroz, Basilio Carrasco, Carmen Bravo, Rolando Garcia-Gonzales
American Journal of Plant Sciences (AJPS) , 2013, DOI: 10.4236/ajps.2013.45126

A new procedure for blueberry (Vaccinium corymbosum L.) micropropagation in programmed Temporary Immersion Bioreactors (TIBs based on two separate bottles) was developed for the commercial genotypes Biloxi, Sharp Blue and Brillita. Plant cultures were developed in a controlled environment with 0.4 MPa CO2 enrichment, sucrose-reduced medium, and light intensity of 60 mM m-2·s-1. Principal component analysis showed that component 1 (C1) grouped 64.08% of the total variability, while the first two components accounted for 86.97%. Representation of the principal components demonstrated three clusters corresponding with the blueberry genotypes, and within each cluster plants micropropagated in agar-base medium grouped separately from those plants multiplied in TIBs. Both plant number and total internodes traits (related to the productive efficiency) were demonstrated superior in blueberries propagated in TIBs. Additionally, when transferred to greenhouse conditions, blueberries propagated in TIBs showed higher adaptability and growing rates than those cultured by the conventional approach, altogether evidencing the occurrence of a photomixotrophic stage in the vitroplantlets cultured in TIBs.

Abstract: domiciliary prison is an alternative for those inmates that having paid a fraction of their effective time term in prison are considered eligible to finish it off at their own homes. in the federal district, brazil, this process of social insertion is hindered by highly vulnerable conditions -social, spatial, individual and institutional- of this population. in order to reach a more in-depth knowledge of these questions, we interviewed, through a semi-structured format, 175 former inmates enjoying the aforementioned legal condition. we established that poor mental health, fueled by the consumption of alcohol and other drugs, aggravates the expected inequality of opportunities in education, health and decent employment suffered by this population, and hinder their social rehabilitation, increasing all along the probability of returning to a life of crime.

Abstract: El régimen penal de prisión domiciliaria está destinado principalmente a aquellas personas que habiendo pasado por un período de prisión efectiva, progresan hacia este tipo de medida como paso previo a la finalización de su condena. En el Distrito Federal de Brasil este proceso de inserción social se ve dificultado por las condiciones de vulnerabilidades sociales, individuales e institucionales de esta población. Con el fin de profundizar el conocimiento acerca de estas cuestiones fueron entrevistados 175 sujetos en esta condición sociojurídica, por medio de entrevistas semi-estructuradas. Como resultado se puede afirmar que las dificultades de acceso a educación, salud y condiciones dignas de empleo en general se suman a factores relacionados con la salud mental de esta población, entre ellos el consumo de alcohol y otras drogas, lo que dificulta su inserción social y aumenta las probabilidades de reincidencia penal.

Open Journal of Respiratory Diseases (OJRD) , 2012, DOI: 10.4236/ojrd.2012.22003
Abstract: Background: Pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) are serious diseases with similar pathophysiologic aspects. The prognosis of patients with these conditions is highly uncertain, particularly incident cases. Methods: A Cox proportional hazards model was applied to a group of 85 patients (81% women, mean age 52 (18 - 82) years) with PAH (80%) and non-surgical CTEPH (20%) to evaluate risk factors for mortality. The following variables were included in the model: age, etiology, baseline 6-minute walk test (6 mWT), cardiac index, and improvement in the 6 mWT following initiation of first medical treatment. Results: In the multivariate analysis, the response to treatment, assessed by an improvement on the 6 mWT, was the most relevant prognostic factor in these patients (RR, 4.832 (95% CI, 1.888 - 12.364); p = 0.001). The remaining variables studied in this model had less influence on the prognosis: age > 50 years (RR, 0.744 (95% CI, 0.26 - 2.133); p = 0.582); etiology of connective tissue disease-associated PAH (RR, 3.145 (95% CI, 0.995-9.946); p = 0.051) or CTEPH (RR, 0.654 (95% CI, 0.179 - 2.387); p = 0.521) with respect to idiopathic PAH; baseline 6 mWT (RR, 1.173 (95% CI, 0.599 - 4.895); p = 0.315); or cardiac index (RR, 2.295 (95% CI, 0.793 - 6.642); p = 0.125). Conclusions: There is a high degree of uncer-tainty regarding the prognosis of PAH and CTEPH at the start of appropriate treatment. Our results support the idea that the initial treatment response is of paramount importance as prognostic factor in these patients.

Abstract: In cultured neonatal rat ovaries, NGF increased VEGF mRNA and protein levels, whereas TGFbeta1 expression did not change. Sectioning of the superior ovarian nerve, which increases ovarian NGF protein content, augmented VEGF immunoreactivity and the area of capillary vessels in ovaries of prepubertal rats compared to control ovaries.Results indicate that NGF may be important in the maintenance of the follicular and luteal vasculature in adult rodents, either indirectly, by increasing the expression of VEGF in the ovary, or directly via promoting the proliferation of vascular cells. This data suggests that a disruption on NGF regulation could be a component in ovarian disorders related with impaired angiogenesis.Angiogenesis is an essential process in follicular development and luteogenesis [1,2]. Once the proliferation of new blood vessels is complete, a rapid capillary regression takes place in the non-fertile cycle which suggests a delicate coordination between angiogenesis inducers and inhibitors [3]. The intervention of ovarian vascularization has an adverse effect on the growth of the dominant follicle, the ovulation and the functioning of the corpus luteum and its ability to secrete progesterone [1,4].The regulation of cyclic angiogenesis in the ovary is commanded by a variety of growth factors; vascular endothelial growth factor (VEGF) playing a major role by stimulating vessel hyperpermeability, endothelial cell proliferation and migration [5]. Several splicing isoforms are generated from VEGF gene, and the proteins reach endothelial cells either by difussion of the shorter isoforms (VEGF 121, VEGF 165) or following proteolitic cleavage of longer ones (VEGF 189, VEGF 206) [3]. The mRNAs for the isoforms of 121 and 165 aminoacids are dominant in normal human ovaries [5]. In rodents, VEGF isoforms are one aminoacid shorter than in human, and have a similar distribution and function [6,7]. Another molecule that modulates angiogenesis is the transforming growth f
