Eleven questions on Hantavirus cardiopulmonary syndrome management in the ICU

Hantavirus cardiopulmonary syndrome (HCPS) due to Andes virus (ANDV) is a fulminant yet potentially reversible cause of respiratory and circulatory failure requiring timely critical care. This article addresses eleven practical questions on ICU management, drawing on clinical exp...

Misunderstanding and Overprotection: The Impact of Research Ethics Committees on Social Disability Studies in Chile

This study explores the experiences of researchers in Chile when submitting disability-related projects to Research Ethics Committees. Through a qualitative approach involving 18 semi-structured interviews with researchers, the study identifies the barriers that arise from applyi...

Mating-Induced Behavioral Changes in Female Drosophila Are Modulated by Serotonin

Mating influences the physiology of female animals and induces changes in behaviors associated with securing resources for their offspring. Modulatory neurotransmitters are known to adjust behavioral responses of animals according to environmental cues and internal physiological...

Functional partitioning among core and peripheral bacteria shapes the giant kelp holobiont

The giant kelp Macrocystis pyrifera hosts diverse microbial communities integral to its ecological function, yet the distribution of microbial functions across different holobionts remains poorly resolved. Here, we used genome-resolved metagenomics to examine how microbial occupa...

The Resilient and the Vulnerable: Root-Associated Fungal Communities in the Regeneration of Nothofagus pumilio Forest Eight Years After Fire

Wildfires are increasing in frequency and severity worldwide, with long-lasting effects on forest vegetation and fungal communities essential for seedling establishment and forest resilience. Nothofagus pumilio, the dominant tree of South American temperate forests, forms key fun...

Tackling Waste of Fruits and Vegetables in Chilean Households with Tailored Informational–Enablement Interventions: A Randomized Controlled Pilot Study

Randomized Controlled Trials (RCTs) and direct measurement of waste are the gold standards for evaluating food waste interventions. This pilot RCT explored the effects of a 3-week tailored informational–enablement intervention to reduce the causes and amount of fruit and vegetabl...
