Orientador: Ranulfo Monte AlegreDissertação (mestrado) - Universidade Estsadual de Cam,pinas, Faculdade de Engenharia de AlimentosResumo: O interesse pela produção de ácido láctico tem crescido fortemente nos últimos anos desde a descoberta das propriedades de seus polímeros, os que apresentam caraterísticas de biodegradabilidade e biocompatibilidade; e sua aplicação como solvente ¿verde¿ ou ambientalmente saudável para os processos de misturas de solventes na indústria química. Dado o potencial econômico do ácido láctico, são necessários processos mais eficazes para sua síntese e redução dos custos de produção. Este trabalho visou aperfeiçoar o processo de produção fermentativa do ácido láctico, determinando formulações do meio de cultura que auxiliarão no desenvolvimento de tecnologias competitivas de produção. Além disso, esse trabalho propõe a utilização de matérias-primas de baixo custo e grande disponibilidade no mercado brasileiro como por exemplo melaço de cana e água de maceração de milho. A espécie selecionada para o estudo foi Lactobacillus delbrueckii, duas linhagens foram estudadas, selecionando-se a que apresentou maior velocidade de crescimento e produção de ácido láctico no meio de cultura padrão. O estudo de otimização da produção de ácido láctico foi realizado utilizando a estratégia de planejamentos experimentais. O uso de melaço de cana e água de maceração de milho como fonte de carbono e nitrogênio, em concentração de 240 gL-1 e 14 gL-1 respectivamente, possibilitou produtividade de até 57,17 gL-1 após 96 horas, com eficiência de 82% (gramas de ácido láctico produzido / grama de substrato utilizado)Abstract: The interest in lactic acid has grown strongly in the last years since the discovery of its properties of application in production of biodegradable and biocompatible polylactate polymers and their application as "green solvent¿ or ¿safety solvent¿ to processes of mixtures of solvents in the chemical industry. Considering the commercial potential of lactic acid, more efficient processes are needed for its synthesis, reducing costs of production and turning its industrial application more atractive, as its cost still prevents it from being used in some areas. This work aimed at improving the process of fermentative lactic acid production, determining formulations that will help develop competitive technologies of production. Furthermore, the use of low cost raw materials, easily available on the brazilian market, such as sugarcane molasses and corn steep liquor is proposed. The species selected for the study was Lactobacillus delbrueckii, two strains were studied, Lactobacillus delbrueckii spp. bulgaricus, shown the greatest growth speed and lactic acid production in the standard culture medium. The optimization study of lactic acid production was performed using the strategy of experimental design, using sugarcane molasses as a carbon source and corn steep liquor as a nitrogen source allowed a productivity of up to 57,17 gL-1 after 96 hours, with 82% lactic acid yield efficiency (g lactic acid produced / g substrate utilized) using an initial concentration of 240 gL-1 and 14 gL-1 of sugarcane molasses and corn steep liquor respectivelyMestradoEngenharia de AlimentosMestre em Engenharia de Alimento

The trophectoderm acts as a niche for the inner cell mass through C/EBPα-regulated IL-6 signaling

Gene regulation; Somatic cell reprogramming; TrophectodermRegulación de genes; Reprogramación de células somáticas; TrofoectodermoRegulació de gens; Reprogramació de cèl·lules somàtiques; TrofectodermaIL-6 has been shown to be required for somatic cell reprogramming into induced pluripotent stem cells (iPSCs). However, how Il6 expression is regulated and whether it plays a role during embryo development remains unknown. Here, we describe that IL-6 is necessary for C/EBPα-enhanced reprogramming of B cells into iPSCs but not for B cell to macrophage transdifferentiation. C/EBPα overexpression activates both Il6 and Il6ra genes in B cells and in PSCs. In embryo development, Cebpa is enriched in the trophectoderm of blastocysts together with Il6, while Il6ra is mostly expressed in the inner cell mass (ICM). In addition, Il6 expression in blastocysts requires Cebpa. Blastocysts secrete IL-6 and neutralization of the cytokine delays the morula to blastocyst transition. The observed requirement of C/EBPα-regulated IL-6 signaling for pluripotency during somatic cell reprogramming thus recapitulates a physiologic mechanism in which the trophectoderm acts as niche for the ICM through the secretion of IL-6.We thank C. Berenguer for help with B cell reprogramming and bone marrow collection; S. Nakagawa and B. Pernaute for advice on pre-implantation embryo culture and manipulation, and Kyle M.

Identificación de plataformas regionales de monitoreo de alta montaña en Colombia

Las áreas montañosas cubren aproximadamente el 25% de la superficie terrestre del mundo y son reconocidas como importantes centros de biodiversidad a nivel regional y mundial (Mittermeier et al. 2011). Dadas las variaciones, a menudo extremas, del clima y la topografía entre distancias geográficas relativamente cortas, las regiones montañosas comúnmente presentan altas tasas de endemismo y gran diversidad biológica a nivel genético, de especies y de ecosistemas (Egan & Price 2017). Por ejemplo, en las montañas se encuentra más del 85% de las especies de anfibios, aves y mamíferos, muchas de las cuales tienen distribuciones restringida (Rahbek et al., 2019). Particularmente, su importancia para la biodiversidad es reconocida en los trópicos, en donde se consideran puntos calientes de riqueza de especies (Rahbek et al. 2019)BogotáCiencias Básicas de la Biodiversida

Global hyperactivation of enhancers stabilizes human and mouse naïve pluripotency through inhibition of CDK8/19 Mediator kinases

Pluripotent stem cells (PSCs) transition between cell states in vitro and reflect developmental changes in the early embryo. PSCs can be stabilized in the naïve state by blocking extracellular differentiation stimuli, particularly FGF-MEK signaling. Here, we report that multiple features of the naïve state in human and mouse PSCs can be recapitulated without affecting FGF-MEK-signaling or global DNA methylation. Mechanistically, chemical inhibition of CDK8 and CDK19 kinases removes their ability to repress the Mediator complex at enhancers. Thus CDK8/19 inhibition increases Mediator-driven recruitment of RNA Pol II to promoters and enhancers. This efficiently stabilizes the naïve transcriptional program and confers resistance to enhancer perturbation by BRD4 inhibition. Moreover, naïve pluripotency during embryonic development coincides with a reduction in CDK8/19. We conclude that global hyperactivation of enhancers drives naïve pluripotency, and this can be achieved in vitro by inhibiting CDK8/19 kinase activity. These principles may apply to other contexts of cellular plasticity

Factors associated with the need of parenteral nutrition in critically ill patients after the initiation of enteral nutrition therapy

Background and aimsDespite enteral nutrition (EN) is the preferred route of nutrition in patients with critical illness, EN is not always able to provide optimal nutrient provision and parenteral nutrition (PN) is needed. This is strongly associated with gastrointestinal (GI) complications, a feature of gastrointestinal dysfunction and disease severity. The aim of the present study was to investigate factors associated with the need of PN after start of EN, together with the use and complications associated with EN.MethodsAdult patients admitted to 38 Spanish intensive care units (ICUs) between April and July 2018, who needed EN therapy were included in a prospective observational study. The characteristics of EN-treated patients and those who required PN after start EN were analyzed (i.e., clinical, laboratory and scores).ResultsOf a total of 443 patients, 43 (9.7%) received PN. One-third (29.3%) of patients presented GI complications, which were more frequent among those needing PN (26% vs. 60%, p = 0.001). No differences regarding mean energy and protein delivery were found between patients treated only with EN (n = 400) and those needing supplementary or total PN (n = 43). Abnormalities in lipid profile, blood proteins, and inflammatory markers, such as C-Reactive Protein, were shown in those patients needing PN. Sequential Organ Failure Assessment (SOFA) on ICU admission (Hazard ratio [HR]:1.161, 95% confidence interval [CI]:1.053–1.281, p = 0.003) and modified Nutrition Risk in Critically Ill (mNUTRIC) score (HR:1.311, 95% CI:1.098–1.565, p = 0.003) were higher among those who needed PN. In the multivariate analysis, higher SOFA score (HR:1.221, 95% CI:1.057–1.410, p = 0.007) and higher triglyceride levels on ICU admission (HR:1.004, 95% CI:1.001–1.007, p = 0.003) were associated with an increased risk for the need of PN, whereas higher albumin levels on ICU admission (HR:0.424, 95% CI:0.210–0.687, p = 0.016) was associated with lower need of PN.ConclusionA higher SOFA and nutrition-related laboratory parameters on ICU admission may be associated with the need of PN after starting EN therapy. This may be related with a higher occurrence of GI complications, a feature of GI dysfunction.Clinical trial registrationClinicalTrials.gov: NCT03634943

What pulmonologists think about the asthma–COPD overlap syndrome

Background: Some patients with COPD may share characteristics of asthma; this is the so-called asthma–COPD overlap syndrome (ACOS). There are no universally accepted criteria for ACOS, and most treatments for asthma and COPD have not been adequately tested in this population. Materials and methods: We performed a survey among pulmonology specialists in asthma and COPD aimed at collecting their opinions about ACOS and their attitudes in regard to some case scenarios of ACOS patients. The participants answered a structured questionnaire and attended a face-to-face meeting with the Metaplan methodology to discuss different aspects of ACOS. Results: A total of 26 pulmonologists with a mean age of 49.7 years participated in the survey (13 specialists in asthma and 13 in COPD). Among these, 84.6% recognized the existence of ACOS and stated that a mean of 12.6% of their patients might have this syndrome. In addition, 80.8% agreed that the diagnostic criteria for ACOS are not yet well defined. The most frequently mentioned characteristics of ACOS were a history of asthma (88.5%), significant smoking exposure (73.1%), and postbronchodilator forced expiratory volume in 1 second/forced vital capacity ,0.7 (69.2%). The most accepted diagnostic criteria were eosinophilia in sputum (80.8%), a very positive bronchodilator test (69.2%), and a history of asthma before 40 years of age (65.4%). Up to 96.2% agreed that first-line treatment for ACOS was the combination of a long-acting β2-agonist and inhaled steroid, with a long-acting antimuscarinic agent (triple therapy) for severe ACOS. Conclusion: Most Spanish specialists in asthma and COPD agree that ACOS exists, but the diagnostic criteria are not yet well defined. A previous history of asthma, smoking, and not fully reversible airflow limitation are considered the main characteristics of ACOS, with the most accepted first-line treatment being long-acting β2-agonist/inhaled corticosteroids

TRY plant trait database - enhanced coverage and open access

Plant traits—the morphological, anatomical, physiological, biochemical and phenological characteristics of plants—determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research spanning from evolutionary biology, community and functional ecology, to biodiversity conservation, ecosystem and landscape management, restoration, biogeography and earth system modelling. Since its foundation in 2007, the TRY database of plant traits has grown continuously. It now provides unprecedented data coverage under an open access data policy and is the main plant trait database used by the research community worldwide. Increasingly, the TRY database also supports new frontiers of trait‐based plant research, including the identification of data gaps and the subsequent mobilization or measurement of new data. To support this development, in this article we evaluate the extent of the trait data compiled in TRY and analyse emerging patterns of data coverage and representativeness. Best species coverage is achieved for categorical traits—almost complete coverage for ‘plant growth form’. However, most traits relevant for ecology and vegetation modelling are characterized by continuous intraspecific variation and trait–environmental relationships. These traits have to be measured on individual plants in their respective environment. Despite unprecedented data coverage, we observe a humbling lack of completeness and representativeness of these continuous traits in many aspects. We, therefore, conclude that reducing data gaps and biases in the TRY database remains a key challenge and requires a coordinated approach to data mobilization and trait measurements. This can only be achieved in collaboration with other initiatives
