The DeoR-like pleiotropic regulator SCO1897 controls specialised metabolism, sporulation, spore germination, and phosphorus accumulation in Streptomyces coelicolor.

Streptomycetes are bacteria of significant biotechnological interest due to their production of bioactive specialised metabolites used in medicine and agriculture. In these bacteria, specialised metabolism and morphological differentiation are linked and typically repressed under high phosphate conditions. This study characterises a DeoR-like transcriptional regulator, SCO1897, in Streptomyces coelicolor, whose expression increases during sporulation.

Essential Genes Discovery in Microorganisms by Transposon-Directed Sequencing (Tn-Seq): Experimental Approaches, Major Goals, and Future Perspectives.

Essential genes are crucial for microbial viability, playing key roles in both the primary and secondary metabolism. Since mutations in these genes can threaten organism viability, identifying them is challenging. Conditionally essential genes are required only under specific conditions and are important for functions such as virulence, immunity, stress survival, and antibiotic resistance.

Reproductive Decision Making of Spanish Women Living With HIV: A Constructivist Grounded Theory Study.

The process of reproductive decision making among women living with HIV is intricate and multifaceted, influenced by health considerations, societal factors, and personal values. In this study, we employed Charmaz's Constructivist Grounded Theory to understand how Spanish women living with HIV make decisions regarding reproduction. We conducted 26 face-to-face interviews until data saturation was achieved.

Single cell ICP-MS to evaluate the interaction behaviour for Cd, Ce and U with Streptomyces coelicolor spores.

Streptomyces are important soil bacteria used for bioremediation of metal-contaminated soils, however, it is still unknown how metal-selective Streptomyces are and which mechanisms are involved during their capture. In this work, we exposed S. coelicolor spores to environmentally relevant concentrations (0.

Critical thinking among institutional academic advisors and sociodemographic, professional and academic variables: A multicenter correlation study.

Background: In nursing education, essential skills include Critical Thinking (CT). There is scant evidence on how nurse educators could promote CT in students in a clinical context.

Objective: To analyse the level of CT and correlated variables in healthcare nurses overseeing the clinicals of nursing undergraduates.
