A cardiac transcriptional enhancer is repurposed during regeneration to activate an anti-proliferative program.

Zebrafish have a high capacity to regenerate their hearts. Several studies have surveyed transcriptional enhancers to understand how gene expression is controlled during heart regeneration. We have identified REN or the runx1 enhancer that during regeneration regulates the expression of the nearby runx1 gene.

Influence and presumption of the vaccine against Covid-19 in South American families.

Faced with the uncertainty of whether the vaccines against Covid-19 are effective or not and faced with living or dying, it is important to know the perception and expectation of their acceptance. The main aim of the study to analyze the perception and expectation of the vaccine against Covid- 19 that South American families have in an urban area of De Pasco. Descriptive, cross-sectional study, simple random sampling of 197 families.

Impact of Early Enteral Nutrition on the Hospital Stay of Pediatric Patients Undergoing Mechanical Ventilation.

Early initiation of enteral nutrition (EN) in pediatrics has been associated with improved clinical outcomes in critically ill pediatric patients. This research study aimed to measure the effect of early EN in intubated children on the length of stay (LOS) and days of mechanical ventilation (DMV). A retrospective cohort observational study was performed on patients admitted to the pediatric intensive care unit (PICU).

Non-structural carbohydrates mediate seasonal water stress across Amazon forests.

Non-structural carbohydrates (NSC) are major substrates for plant metabolism and have been implicated in mediating drought-induced tree mortality. Despite their significance, NSC dynamics in tropical forests remain little studied. We present leaf and branch NSC data for 82 Amazon canopy tree species in six sites spanning a broad precipitation gradient.

Potential point of care tests (POCTs) for maternal health in Peru, perspectives of pregnant women and their partners.

Background: Globally, no qualitative studies have explored the perspectives of women and their partners about the integration of technology - and specifically diagnostic testing technologies - into antenatal care. The study objective was to describe the demand side for pregnancy-related diagnostic tests from the perspective of Peruvian consumers, including female and male community members, by engaging participants about their awareness of and care-seeking for pregnancy-related diagnostic tests and their preferred characteristics and testing conditions for pregnancy-related point-of-care diagnostic tests (POCTs).

Methods: Sixty-seven mothers and fathers of children under one from the peri-urban coast and the peri-urban and rural highlands and jungle of Peru participated in ten focus groups.
