Volvamos Juntos: evaluation of the implementation of a Social Health Intervention to mitigate the impact of Covid-19 in businesses in Antofagasta, Chile.

Background: The COVID-19 pandemic has had an impact not only on healthcare but also on labor and socioeconomic sectors worldwide, leading to the development of strategies to mitigate the crisis' widespread repercussions. In Antofagasta, Chile, an innovation project entitled Volvamos Juntos ("Let's Return Together") was developed to support a diverse group of micro and small businesses. The project consisted of accompanying companies in the process of reopening safely and included interventions ranging from educating and testing employees for COVID-19 to developing protocols to avoid contagion and other preventive measures.

Declining activity of serum response factor in aging aorta in relation to aneurysm progression.

Age is a critical determinant of arterial disease, including aneurysm formation. Here, to understand the impact of aging on the arterial transcriptome, we leveraged RNA-sequencing data to define transcripts that change with advancing age in human arteries. Among the most repressed transcripts in aged individuals were those that are relevant for actomyosin structure and organization, including both myosin light chain kinase (MYLK) and smooth muscle γ-actin (ACTG2).

Dual neuromodulatory dynamics underlie birdsong learning.

Although learning in response to extrinsic reinforcement is theorized to be driven by dopamine signals that encode the difference between expected and experienced rewards, skills that enable verbal or musical expression can be learned without extrinsic reinforcement. Instead, spontaneous execution of these skills is thought to be intrinsically reinforcing. Whether dopamine signals similarly guide learning of these intrinsically reinforced behaviours is unknown.

Diversity, management, and uses of edible plants in a Ñäñho community of Southern Querétaro, Mexico.

Background: Mexico is one of the countries with the highest cultural, biological, and agrobiological diversity. However, an accelerated process of ancestral knowledge loss, related to the management of agrobiodiversity, native seeds, and other edible plant species management is affecting food sovereignty. This process of knowledge loss was documented at the Ñäñho region, of southern Querétaro, where our study took place.

Comprehensive analysis of antimicrobial resistance, biofilm formation and virulence factors of staphylococci isolated from bovine mastitis.

Bovine mastitis, a prevalent disease, is often attributed to staphylococci species. These microorganisms can express a diverse array of virulence genes and have the capability to form biofilms, establishing a robust defense against antimicrobials and host immune responses. In this study, we analyzed 191 spp.
