[The interface between public policies for the unhoused population: an integrative review].

The heterogeneous and vulnerable nature of the unhoused population reveal the complexity of living on the street and call for the State to play a fundamental role in the provision of health and social care policies. The scope of this study was to evaluate the intersectorality between health policies, social protection and organized civil society actions for the unhoused population in Brazil, based on an integrative literature review. To achieve this, a search was conducted in the SciELO, LILACS and PubMed databases, from which ten articles published between 2004-2021, all of a qualitative nature, were selected.

An optical aptasensor for real-time quantification of endotoxin: From ensemble to single-molecule resolution.

Endotoxin is a deadly pyrogen, rendering it crucial to monitor with high accuracy and efficiency. However, current endotoxin detection relies on multistep processes that are labor-intensive, time-consuming, and unsustainable. Here, we report an aptamer-based biosensor for the real-time optical detection of endotoxin.

Sleep deprivation affects sexual behavior and tyrosine hydroxylase (TH) levels in sexually experienced male rats.

Paradoxical sleep deprivation (PSD) produces alterations in dopaminergic systems and also modifies sexual behavior. In this work we evaluated PSD effects on the sexual response and tyrosine hydroxylase (TH) expression in dopaminergic pathways related to sexual behavior of naive and sexual experienced rats. Male Wistar rats had their sexual behavior evaluated in 6 copulatory tests, with a 4 days interval.
