Covert variations of a musician's loudness during collective improvisation capture other musicians' attention and impact their interactions.

While research on auditory attention in complex acoustical environment is a thriving field, experimental studies thus far have typically treated participants as passive listeners. The present study-which combined real-time covert loudness manipulations and online probe detection-investigates for the first time to our knowledge, the effects of acoustic salience on auditory attention during live interactions, using musical improvisation as an experimental paradigm. We found that musicians were more likely to pay attention to a given co-performer when this performer was made sounding louder or softer; that such salient effect was not owing to the local variations introduced by our manipulations but rather likely to be driven by the more long-term context; and that improvisers tended to be more strongly and more stably coupled when a musician was made more salient.

Continuous colonization of the Atlantic coastal rain forests of South America from Amazônia.

The two main extensions of rain forest in South America are the Amazon (Amazônia) and the Atlantic rain forest (Mata Atlântica), which are separated by a wide 'dry diagonal' of seasonal vegetation. We used the species-rich tree genus to test if Amazônia-Mata Atlântica dispersals have been clustered during specific time periods corresponding to past, humid climates. We performed hybrid capture DNA sequencing of 810 nuclear loci for 453 accessions representing 164 species that included 62% of Mata Atlântica species and estimated a dated phylogeny for all accessions using maximum likelihood, and a species-level tree using coalescent methods.

Excipients in drug delivery systems: A comprehensive review of approved inactive ingredients for human ophthalmic formulations.

Pharmaceutical excipients, commonly known as inactive ingredients, encompass any substance aside from the active ingredient that fulfills a distinct and vital role in a formulation. Their purpose is to enhance specific characteristics, whether associated with the performance of the formulation or aspects related to patient comfort, safety, and acceptability. Because of the limited toxicity studies provided, and the several allergic and toxic side effects that have been reported throughout the years, it is not trivial for the regulatory agencies to approve inactive ingredients for human use.

Synergistic activity of Pitstop-2 and 1,6-hexanediol in aggressive human lung cancer cells.

Metastatic cancer cells undergo metabolic reprogramming, which involves changes in the metabolic fluxes, including endocytosis, nucleocytoplasmic transport, and mitochondrial metabolism, to satisfy their massive demands for energy, cell division, and proliferation compared to normal cells. We have previously demonstrated the ability of two different types of compounds to interfere with linchpins of metabolic reprogramming, Pitstop-2 and 1,6-hexanediol (1,6-HD). 1,6-HD disrupts glycolysis enzymes and mitochondrial function, enhancing reactive oxygen species production and reducing cellular ATP levels, while Pitstop-2 impedes clathrin-mediated endocytosis and small GTPases activity.
