Early career researchers (ECRs) are important stakeholders leading efforts to catalyze systemic change in research culture and practice. Here, we summarize the outputs from a virtual unconventional conference (unconference), which brought together 54 invited experts 20 countries with extensive experience ECR initiatives designed improve practice of science. Together, drafted 2 sets recommendations for (1) ECRs directly involved or activities practice; (2) who wish support these efforts....
ABSTRACT Salmonella enterica serovar Enteritidis causes a systemic, typhoid-like infection in newly hatched poultry and mice. In the present study, library of 54,000 transposon mutants S. phage type 4 (PT4) strain P125109 was screened for deficient vivo colonization BALB/c mouse model using microarray-based negative-selection screening. Mutants genes known to contribute systemic (e.g., pathogenicity island 2 [SPI-2], aro , rfa rfb phoP phoQ ) enteric SPI-1 SPI-5) this other serovars...
The need to protect public health during the current COVID-19 pandemic has necessitated conference cancellations on an unprecedented scale. As scientific community adapts new working conditions, it is important recognize that some of our actions may disproportionately affect early-career researchers and scientists from countries with limited research funding. We encourage all organizers, funders institutions who are able do so consider how they can mitigate unintended consequences travel we...
In the present work, we report use of bacterial cells for production CdS/CdSe Core/Shell quantum dots (QDs), a complex nanostructure specially designed to improve their performance as photosensitizer in photovoltaic devices. The method requires incorporation L-cysteine, CdCl2 and Na2SeO3 Escherichia coli cultures allows tight control QDs properties. obtained were photophysically structurally characterized. When compared CdS QDs, classical shift UV-visible spectra nanostructures was observed...
Abstract Background Microbes are present in almost every environment on Earth, even those with extreme environmental conditions such as Antarctica, where rocks may represent the main refuge for life. Lithobiontic communities composed of microorganisms capable colonizing and, it is a not so well studied bacterial community, they very interesting source diversity and functional traits potential biotechnological applications. In this work we analyzed ability Antarctic lithobiontic bacterium to...
Recently, we reported the production of Cadmium sulfide (CdS) fluorescent semiconductor nanoparticles (quantum dots, QDs) by acidophilic bacteria Acidithiobacillus genus. Here, report that addition inorganic phosphate to thiooxidans ATCC 19703 cultures favors biosynthesis CdS QDs at acidic conditions (pH 3.5). The effect pH, and cadmium concentrations on was studied using Response Surface Methodology (RSM), a multivariate technique for analytical optimization scarcely used in microbiological...
CuInS2 (CIS) nanoparticles have unique chemical, toxicological and optoelectronic properties that favor their technological applications. In the present work we report a novel one step biomimetic method for aqueous synthesis of CIS nanoparticles, is also low cost environmentally friendly. This uses only CuSO4 InCl3 as precursor salts, biological molecule glutathione sulfur donor stabilizer (NPs). The reaction performed at temperatures, under aerobic conditions atmospheric pressure. produced...
Background: Healthcare-associated infections (HAIs) significantly increase morbidity, mortality, and healthcare costs. Among HAIs, catheter-associated are particularly prevalent due to the susceptibility of catheters microbial contamination biofilm formation, especially with prolonged use. Biofilms act as infection reservoirs, complicating treatment often requiring catheter removal, thus extending hospital stays increasing Recent technological advances in design have focused on integrating...
The eLife Early-Career Advisory Group (ECAG), an international group of early-career researchers committed to improving research culture, calls for radical changes at and other journals address racism in the scientific community make science more diverse inclusive.
The availability of the complete genome sequence several Salmonella enterica serovars has revealed presence unstable genetic elements in these bacteria, such as pathogenicity islands and prophages. This is case serovar Enteritidis (S. Enteritidis), a bacterium that causes gastroenteritis humans systemic infection mice. whole analysis for S. unveiled regions are absent other serovars. These have been denominated "regions difference" (ROD). In this study we show ROD21, one regions, behaves an...
Salmonella enterica serovar Enteritidis has emerged as a major health problem worldwide in the last few decades. DNA loci unique to S. can provide markers for detection of this pathogen and may reveal pathogenic mechanisms restricted serovar. An silico comparison 16 genomic sequences revealed presence an approximately 12.5-kb island (GEI) specific sequenced strain NCTC13349. The GEI is inserted at 5' end gene ydaO (SEN1377), flanked by 308-bp imperfect direct repeats (attL attR), includes 21...
The renin-angiotensin system expressed in adipose tissue has been implicated the modulation of adipocyte formation, glucose metabolism, triglyceride accumulation, lipolysis, and onset adverse metabolic consequences obesity. As we investigated angiotensin II signal transduction mechanisms human preadipose cells, an interplay extracellular-signal-regulated kinases 1 2 (ERK1,2) Akt/PKB became evident. Angiotensin caused attenuation phosphorylated Akt (p-Akt), at serine 473; p-Akt/Akt ratio...
Early career researchers (ECRs) are important stakeholders leading efforts to catalyze systemic change in the conduct and communication of science. Here, we summarize outputs from a virtual unconventional conference (unconference), which brought together 54 invited experts 20 countries with extensive experience ECR initiatives designed improve The event was focused on why ECRs needed science obstacles they face when trying promote reform. Our discussions also highlighted additional that...
The eLife Early-Career Advisory Group discusses eLife's new peer review and publishing model, how the whole process of scientific communication could be improved for benefit early-career researchers entire community.
A.T. Still University School of Osteopathic Medicine in Arizona (ATSU-SOMA) has an established partnership with Family HealthCare Network (FHCN). Initial meetings the local community outreach department identified that a substantial majority Hispanic population served by this health center may lack access to education. In particular, Spanish-speaking patients at face language barriers impair transfer education between providers, patients, and their families.
