US State Public Health Agencies' Use of Twitter From 2012 to 2022: Observational Study.

Background: Twitter (subsequently rebranded as X) is acknowledged by US health agencies, including the US Centers for Disease Control and Prevention (CDC), as an important public health communication tool. However, there is a lack of data describing its use by state health agencies over time. This knowledge is important amid a changing social media landscape in the wake of the COVID-19 pandemic.

Neuroendocrine and Developmental Impacts of Early Life Exposure to EDCs.

Polychlorinated biphenyls (PCBs) pose a global challenge to environmental and human health. Although toxic and carcinogenic at higher exposure levels, at lower concentrations they can act as endocrine-disrupting chemicals. Individuals are more vulnerable to endocrine-disrupting effects of PCB exposures during the perinatal period, when the neuroendocrine system is developing, although assessing the full impact of PCB exposure is difficult because of the often-latent onset of adverse effects.

The Complete Genome Sequence of (Fringillidae, Passeriformes), the Puerto Rican Euphonia.

The Puerto Rican Euphonia () was recognized as an endemic species in 2023 based solely on morphological differences. A brightly plumaged finch that inhabits a variety of habitats, including lowland dry, scrub forests and shade-coffee plantations (Carlo et. al 2004).

Growth of (Rainbow Trout) through a Recirculation System in the Foothills of the Extreme North of Chile.

Given the overexploitation of fisheries and the growing consumption of sea products, aquaculture is emerging as an alternative to meet the demand for protein at regional, national, and global levels. In northern Chile, the foothills of the Andes offer an opportunity for sustainable economic diversification. In this study, results of a rainbow trout () culture in a recirculation system are presented, analyzing its growth and performance under altitude conditions.
