Implementation of the Indigenous Health Policy: an ethnographic analysis of healthcare practices in the Upper Solimões River.

This study analyzes the implementation of the Indigenous Health Policy, focusing on the care practices of health teams of the Indigenous Health Care Subsystem in the Upper Solimões River in the Amazon region. Using ethnography as a methodological resource, the dynamics among participants, discourses, and power in the implementation of the policy are investigated, revealing a complex interconnection between practices and other contextual realities. Three phenomena emerge as critical influences on care practices: the medical-care model, the sanitation model, and the culture of performance.

Decoding epigenetic markers: implications of traits and genes through DNA methylation in resilience and susceptibility to mastitis in dairy cows.

Cattle farming faces challenges linked to intensive exploitation and climate change, requiring the reinforcement of animal resilience in response to these dynamic environments. Currently, genetic selection is used to enhance resilience by identifying animals resistant to specific diseases; however, certain diseases, such as mastitis, pose difficulties in genetic prediction. This study introduced the utilization of enzymatic methyl sequencing (EM-seq) of the blood genomic DNA from twelve dairy cows to identify DNA methylation biomarkers, with the aim of predicting resilience and susceptibility to mastitis.

Is prolonged luteal phase a problem in lactating Holstein cows?

In this study, the main objective was to assess if long luteal phases could have causes other than pregnancy loss. We enrolled Holstein dairy cows ≥50 DIM from a commercial herd in Brazil from October 2016 to August 2017. All cows received an estradiol-based synchronization protocol, and, on the day of insemination (d 0), were randomly assigned either an AI or a placebo insemination (PBO) in a 3:1 ratio.
