The productive efficiency of rearing herds in Pastaza, Ecuador

Diócles Benítez Verena Torres Julio César Vargas Burgos Sandra Soria

in the rearing- fattening system in Pastaza province, located in the Ecuadorian Amazonia, a non-experimental design was used which controlled the effects of the climatic areas and height levels. For the information processing the Statistical Model of Impact Measuring (MEMI) was applied. It was found that the factors which determine the efficiency of meat production in cattle rearing were reproduction, land relief and looses in the herd, these factors explain 85.54% of the system accumulated variance. These factors are related with the productive process efficiency, relief characteristics, environmental degradation and animals looses. The rearing- fattening systems are classified in four groups, differentiated by the herd size which exploit, the relief where are located, the production process efficiency and the impact they have on the environment. The productive efficiency is low and it correspond with the widespread exploitation alternatives, which are not fit to the environment demands, and with the ability to use the land on which these production processes are developed. It is possible to implement sustainable alternatives of meat production from cattle rearing-fattening systems, if the production systems are fit to the environments demands where these systems are developed. Key words: animal husbandry, impact model, productive chain, Amazonia

Detección y prevalencia de patógenos periodontales de una población con periodontitis crónica en Uruguay mediante metodología convencional y metagenómica

Odontoestomatología (2015)

Virginia Papone Carolina Verolo Lourdes Zaffaroni Alicia Batlle Claudia Capó

Periodontal diseases are a major problem in human health. Decades of research have shown that the most common disease is chronic periodontitis, cha-racterized by a slow evolution with the formation of periodontal pockets, subsequent alveolar bone resorption, loss and destruction of teeth and bone tissue. While we know the multifactorial origin of the development of periodontitis, the participation of subgingival microbiota is relevant in the etiology of periodontal disease. Some pathogenic bacteria species that have been associated with the develo-pment of periodontal disease are Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Prevotella intermedia, Tannerella forsythia, Fusobac-terium nucleatum, among others. In this work we studied which of these five species were present in the periodontal pockets of 51 Uruguayan patients with chronic periodontitis. To achieve the results a conventional microbiological technique and meta-genomics (multiplex-PCR) were used. The results of the microbiological conventional technique showed the presence of A. actinomycete-mcomitans (33%) and black pigmented anaerobic bacteria (100%) in the samples. From the results obtained in the multiplex-PCR we saw that the most prevalent species were F. nucleatum (100%), T. forsythia (92%) and P. gingivalis (88%). In con-trast, lower prevalence species were P. intermedia (39%) and A. actinomycetecomitans (33%).

New insights on transcriptional responses of genes involved in carbon central metabolism, respiration and fermentation to low ATP levels in Escherichia coli

Journal of Basic Microbiology (2012)

Sandra Soria R. Anda Noemí Flores Susana Romero-García Guillermo Gosset

Abstract Adenosine‐5‐triphosphate (ATP) plays a fundamental role in many cellular processes such as transport, central carbon metabolism, biosynthetic reactions, macromolecular synthesis, signal transduction and cellular division. In addition, the intracellular [ATP]/[ADP] ratio in Escherichia coli plays an important role in controlling the specific rates of growth (µ), glucose consumption (q Glc ) and oxygen uptake (q O2 ), as well as the transcriptome pattern in the cell, as was recently reported. In the current study, the energetic level (expressed as [ATP]/[ADP] ratio) was substantially reduced in E. coli strains by either over‐expressing the F 1 ‐ATPase activity (JMAGD + ) or inactivating ATP synthase (JM at − ). The physiological characterization of the wild‐type JM101 strain and its derivative JMAGD + and JM atp − strains was conducted in bioreactors containing minimal medium with glucose. The inactivation of the atp operon and F 1 ‐ATPase overexpression significantly diminished the energetic level and cAMP concentration in derivative strains. Relative transcription levels of 105 genes involved in glucose transport, glycolysis, tricarboxylic acid (TCA) cycle, fermentation, respiration, transcriptional regulators, transcription and genes involved in stress were determined by using qPCR. Interestingly, in the JMAGD + and JM atp − strains, having a reduced energetic level, many transcripts of glycolysis, TCA cycle and respiratory genes were down‐regulated when compared to wild type JM101. The transcriptional responses, detected in the strains with reduced energetic level show down‐regulation of genes involved in central carbon metabolism and respiration, these results are apposite to the observed trends of increased metabolic fluxes in glucose consumption, glycolysis, acetate synthesis, TCA cycle and respiration. Regulation mediated by CRP‐cAMP complex may explain some observed transcriptional responses of TCA cycle genes, since cAMP concentration and crp transcript level were significant reduced in the JM atp − mutant. Therefore, the substantial reduction of [ATP]/[ADP] ratio had a relevant effect on the CRP‐cAMP regulatory system (among other global regulators), which may trigger an extensive transcriptional response.

Rosaura Gutiérrez Valerio de May Elisa López Eluzinete Pereira Eduardo Campaña Sandra Soria

In the Amazon State University (UEA) in the Ecuadorian Amazon, a program was initiated Integral Human Development, applying the methodology of the TCI. As first results of the Chatting Circles (term used in the university context for TCI), the findings of the participants, highlighting that the topics serve them as a contribution to improve their own problems, they feel relief and greater confidence present, as well as greater confidence and solidarity with classmates. This confirms that the meetings contribute to the creation of solidarity networks.

Cadenas agroalimentarias territoriales. Tensiones y aprendizajes desde el sector lácteo de la Amazonía ecuatoriana

Lecturas de Economía (2016)

Sandra Ríos Diócles Benítez Sandra Soria

Farmers participating in the dairy food chain in the province of Pastaza, Ecuadorian Amazon, face major difficulties. Their weak bargaining power, cost structures above price, significant dependence on the market and low value added are important challenges for farmers themselves and for public management. In this sense, the Amazon Productive Transformation Agenda, a new paradigm for public policy in this territory, is a challenging initiative. This research analyzes the conditions that enable local producers, as actors of the agro-food chain, to strengthen their position before other subsectors. To this end, we use the methodological approach of Montpellier and territorial agro-food chains, both of which have allowed us to shape the low negotiating power of local actors as explained by poor collective action that limits the enhancement of endogenous resources in the territory.

The validity of impressions as a media dose metric in a tobacco public education campaign evaluation: an observational study (Preprint)

Journal of Medical Internet Research (2024)

Kevin Davis Laurel Curry Brian Bradfield David A Stupplebeen Rebecca J Williams

Background Evaluation research increasingly needs alternatives to target or gross rating points to comprehensively measure total exposure to modern multichannel public education campaigns that use multiple channels, including TV, radio, digital video, and paid social media, among others. Ratings data typically only capture delivery of broadcast media (TV and radio) and excludes other channels. Studies are needed to validate objective cross-channel metrics such as impressions against self-reported exposure to campaign messages. Objective This study aimed to examine whether higher a volume of total media campaign impressions is predictive of individual-level self-reported campaign exposure in California. Methods We analyzed over 3 years of advertisement impressions from the California Tobacco Prevention Program’s statewide tobacco education campaigns from August 2019 through December 2022. Impressions data varied across designated market areas (DMAs) and across time. These data were merged to individual respondents from 45 waves of panel survey data of Californians aged 18-55 years (N=151,649). Impressions were merged to respondents based on respondents’ DMAs and time of survey completion. We used logistic regression to estimate the odds of respondents’ campaign recall as a function of cumulative and past 3-month impressions delivered to each respondent’s DMA. Results Cumulative impressions were positively and significantly associated with recall of each of the Flavors Hook Kids (odds ratio [OR] 1.15, P<.001), Dark Balloons and Apartment (OR 1.20, P<.001), We Are Not Profit (OR 1.36, P<.001), Tell Your Story (E-cigarette, or Vaping, product use Associated Lung Injury; OR 1.06, P<.05), and Thrown Away and Little Big Lies (OR 1.05, P<.01) campaigns. Impressions delivered in the past 3 months were associated with recall of the Flavors Hook Kids (OR 1.13, P<.001), Dark Balloons and Apartment (OR 1.08, P<.001), We Are Not Profit (OR 1.14, P<.001), and Thrown Away and Little Big Lies (OR 1.04, P<.001) campaigns. Past 3-month impressions were not significantly associated with Tell Your Story campaign recall. Overall, magnitudes of these associations were greater for cumulative impressions. We visualize recall based on postestimation predicted values from our multivariate logistic regression models. Conclusions Variation in cumulative impressions for California Tobacco Prevention Program’s long-term multichannel tobacco education campaign is predictive of increased self-reported campaign recall, suggesting that impressions may be a valid proxy for potential campaign exposure. The use of impressions for purposes of evaluating public education campaigns may help address current methodological limitations arising from the fragmented nature of modern multichannel media campaigns.
