An Optical Wireless Communication System for Physiological Data Transmission in Small Animals.

In biomedical research, telemetry is used to take automated physiological measurements wirelessly from animals, as it reduces their stress and allows recordings for large data collection over long periods. The ability to transmit high-throughput data from an in-body device (e.g.

Dynamic representation of appetitive and aversive stimuli in nucleus accumbens shell D1- and D2-medium spiny neurons.

The nucleus accumbens (NAc) is a key brain region for motivated behaviors, yet how distinct neuronal populations encode appetitive or aversive stimuli remains undetermined. Using microendoscopic calcium imaging in mice, we tracked NAc shell D1- or D2-medium spiny neurons' (MSNs) activity during exposure to stimuli of opposing valence and associative learning. Despite drift in individual neurons' coding, both D1- and D2-population activity was sufficient to discriminate opposing valence unconditioned stimuli, but not predictive cues.

Seroprevalence of Hepatitis E Virus Among Schistosomiasis mansoni Patients Residing in Endemic Zone in Brazil.

The occurrence of hepatitis E virus (HEV) in patients with Schistosomiasis mansoni (SM) is still poorly understood in Brazil. The objective of this study was to estimate the seroprevalence of anti-HEV IgG in patients with SM and its association with the periportal fibrosis (PPF), assessed by serum markers and ultrasound criteria. This cross-sectional study was carried out in an endemic area in Pernambuco, Brazil, with schistosomal patients who underwent coproscopic survey.

Using expert-modeling videos in telesimulations to teach pediatric and neonatal nursing.

to assess the perception of self-efficacy, self-confidence, and satisfaction of undergraduate nursing students during the use of expert-modeling videos as a learning strategy in the period of social distancing. this was a descriptive study with undergraduates studying disciplines of caring for hospitalized newborns and children at a higher education nursing institution in the interior of the state of São Paulo, Brazil. Activities were organized in three moments, in real time: prebriefing, expert-modeling videos and debriefing.
