The brown howler, , endemic to the Atlantic Forest of Brazil and Argentina, is threatened by habitat loss and fragmentation, hunting, and its susceptibility to yellow fever. Two subspecies have been recognized, but their names, validity, and geographic ranges have been controversial. We obtained samples covering the species' entire distribution in Brazil and Argentina to clarify these issues by investigating their genetic diversity and structure and assessing their evolutionary history.

Objective: To evaluate the performance of plasma metanephrine in AVS for determining aldosterone lateralization in PA, with or without mild autonomous cortisol secretion (MACS).
Methods: Sequential AVS under cosyntropin stimulation was conducted in 58 consecutive patients with PA and indication for AVS.
Purpose: We tested the differences in maximum strength and various parameters of sprint performance between youth backs and forwards. Additionally, we examined the associations among various strength-sprint measures, as well as between unresisted and heavy resisted sprints.
Methods: Thirty-two youth rugby players were assessed at the beginning of the season with the following tests: unresisted and resisted (50% body mass) 30-m sprints and 1-repetition maximum (1RM) in the squat exercise.
The absolute total cross section for electron collisions with acetic acid has been measured using an electrostatic electron spectrometer and linear transmission method for collision energies ranging from 0.4 to 300 eV. Elastic electron scattering from acetic acid within a low-energy range has also been studied theoretically using the Schwinger multichannel and R-matrix methods, in the static-exchange and static-exchange plus polarization levels of approximation for energies up to 15 eV.

These impairments hinder their ability to engage in social interactions and explore their surroundings. However, personalized and continuous sensory stimulation, particularly within the home environment, may play a crucial role in supporting motor and visual development in these children.
