Riboflavin overproduction from diverse feedstocks with engineered.

Riboflavin overproduction bywas achieved by screening synthetic operons, enabling fine-tuned expression of the riboflavin biosynthetic genesThe synthetic operons were designed by means of predicted translational initiation rates of each open reading frame, with the best-performing selection enabling riboflavin overproduction without negatively affecting cell growth. Overexpression of the fructose-1,6-bisphosphatase () and 5-phosphoribosyl 1-pyrophosphate aminotransferase () encoding genes was then done to redirect the metabolic flux towards the riboflavin precursors. The resulting strain produced 8.

Genome-based analyses to learn from and about Paenibacillus sonchi genomovar Riograndensis SBR5T.

Paenibacillus sonchi genomovar Riograndensis SBR5T is a plant growth-promoting rhizobacterium (PGPR) isolated in the Brazilian state of Rio Grande do Sul from the rhizosphere of Triticum aestivum. It fixes nitrogen, produces siderophores as well as the phytohormone indole-3-acetic acid, solubilizes phosphate and displays antagonist activity against Listeria monocytogenes and Pectobacterium carotovorum. Comprehensive omics analysis and the development of genetic tools are key to characterizing and engineering such non-model microorganisms.

Efficacy of Oral Furosemide Test for Primary Aldosteronism Diagnosis.

Factors associated with diet quality among Brazilian individuals with cardiovascular diseases.

Background: An individual's dietary pattern contributes in different ways to the prevention and control of recurrent cardiovascular events. However, the quality of the diet is influenced by several factors. The present study aimed to evaluate the quality of the diet of individuals with cardiovascular diseases and determine whether there is an association between sociodemographic and lifestyle factors.

Metabolic engineering of thermophilic Bacillus methanolicus for riboflavin overproduction from methanol.

The growing need of next generation feedstocks for biotechnology spurs an intensification of research on the utilization of methanol as carbon and energy source for biotechnological processes. In this paper, we introduced the methanol-based overproduction of riboflavin into metabolically engineered Bacillus methanolicus MGA3. First, we showed that B.

Intra-individual Variability of Serum Aldosterone and Implications for Primary Aldosteronism Screening.

Context: Primary aldosteronism (PA) screening relies on an elevated aldosterone to renin ratio with a minimum aldosterone level, which varies from 10 to 15 ng/dL (277-415.5 pmol/L) using immunoassay.

Objective: To evaluate intra-individual coefficient of variation (CV) of aldosterone and aldosterone to direct renin concentration ratio (A/DRC) and its impact on PA screening.

Solidarity, citizenship and social justice: perceptions of social actors about public responses to COVID-19.

This qualitative study aimed to analyze the social actors' perceptions of public responses during the COVID-19 pandemic. We conducted semi-structured interviews with eleven civil society representatives and social movement leaders. We also performed triangulation based on the systematization of opinion papers authored by humanitarian organizations and civil society leaders and published in large-circulation newspapers.

Reflections on research ethics in a public health emergency: Experiences of Brazilian women affected by Zika.

In Brazil, the epicenter of the Zika crisis, brown, black, and indigenous poor women living in municipalities with scarce resources were disproportionally affected. The gendered consequences of the epidemic exposed how intersectional lenses are central to understand the impact of public health emergencies in the lives of women and girls. The demand for Zika-affected children and women to be research participants is relevant for an ethical analysis of participant protection procedures during a crisis.

Improvement of 2,2'-Azobis(2-Methylpropionamidine) Dihydrochloride-Induced Hepatic Redox Imbalance in Swiss Mice and HepG2 Cells by Rutin.

Redox imbalance can lead to irreversible damages to biological functions. In this context, rutin stands out for its antioxidant potential. The objective of this study was to evaluate the acute and chronic effect of rutin on the hepatic redox imbalance.

From Brown Seaweed to a Sustainable Microbial Feedstock for the Production of Riboflavin.

The increasing global demand for food and energy production encourages the development of new production strategies focused on sustainability. Often, microbial bioprocesses rely on food or feed competitive feedstocks; hence, there is a trending need for green substrates. Here, we have proven the potential of brown seaweed biomass as microbial feedstock on account of its content of mannitol and the glucose polymer laminarin.

Evaluation of Heterologous Biosynthetic Pathways for Methanol-Based 5-Aminovalerate Production by Thermophilic .

The use of methanol as carbon source for biotechnological processes has recently attracted great interest due to its relatively low price, high abundance, high purity, and the fact that it is a non-food raw material. In this study, methanol-based production of 5-aminovalerate (5AVA) was established using recombinant strains. 5AVA is a building block of polyamides and a candidate to become the C5 platform chemical for the production of, among others, δ-valerolactam, 5-hydroxy-valerate, glutarate, and 1,5-pentanediol.

Does Interrupting Prolonged Sitting With 10- or 20-Min Standing Attenuate Postprandial Glycemia and Blood Pressure in Middle-Aged and Older Adults With Type 2 Diabetes?

We carried out three types of 2-hr experimental sessions with middle-aged and older adults with Type 2 diabetes in order to examine the acute effect of interrupting prolonged sitting with varying periods of standing on postprandial glycemia and blood pressure (BP): (a) prolonged sitting after breakfast; (b) standing for 10 min, 30 min after breakfast; and (c) standing for 20 min, 30 min after breakfast. Glucose and BP were assessed before and after breakfast. A generalized linear model revealed no significant differences for the incremental area under the curve of glucose between standing for 10 min, 30 min after breakfast, versus prolonged sitting after breakfast (β = -4.

Genomic and Transcriptomic Investigation of the Physiological Response of the Methylotroph to 5-Aminovalerate.

The methylotrophic thermophile can utilize the non-food substrate methanol as its sole carbon and energy source. Metabolism of L-lysine, in particular its biosynthesis, has been studied to some detail, and methanol-based L-lysine production has been achieved. However, little is known about L-lysine degradation, which may proceed via 5-aminovalerate (5AVA), a non-proteinogenic ω-amino acid with applications in bioplastics.
