Simultaneous serotonin and dopamine monitoring across timescales by rapid pulse voltammetry with partial least squares regression.

Many voltammetry methods have been developed to monitor brain extracellular dopamine levels. Fewer approaches have been successful in detecting serotonin in vivo. No voltammetric techniques are currently available to monitor both neurotransmitters simultaneously across timescales, even though they play integrated roles in modulating behavior.

Extended Perinatal Mortality Audit in a Rural Hospital in India.

Objective: The aim of the study is to describe the status of perinatal mortality (PM) in an Indian rural hospital.

Study Design: Retrospective analysis of data was compiled from PM meetings (April 2017 to December 2018) following "Making Every Baby Count: audit and review of stillbirths and neonatal deaths (ENAP or Every Newborn Action Plan)."

Results: The study includes 8,801 livebirths, 105 stillbirths (SBs); 74 antepartum stillbirths [ASBs], 22 intrapartum stillbirths [ISBs], and nine unknown timing stillbirths [USBs]), 39 neonatal deaths or NDs (perinatal death or PDs 144).

Metabolic versatility of freshwater sedimentary archaea feeding on different organic carbon sources.

Members of the phylum Bathyarchaeota and the class Thermoplasmata are widespread in marine and freshwater sediments where they have been recognized as key players in the carbon cycle. Here, we tested the responsiveness of archaeal communities on settled plant debris and sediment from a karstic lake to different organic carbon amendments (amino acids, plant-derived carbohydrates, and aromatics) using a lab-scale microcosm. Changes in the composition and abundance of sediment and biofilm archaeal communities in both DNA and RNA fractions were assessed by 16S rRNA gene amplicon sequencing and qPCR, respectively, after 7 and 30 days of incubation.

Supporting the caregiver-child dyad's relationship: An evaluation of implementation quality in the Chilean Crecer Jugando program.

This study presents an evaluation of the implementation quality of the Chilean program Crecer Jugando (CJ), a 16 weekly sessions group-based parenting program for children 0 to 4 years old and their primary caregivers aiming at promoting positive caregiver-child interaction. The implementation of CJ in two public health care centers (HCC) in Chile's Metropolitan Region was assessed based on Donabedian's theoretical model, focusing on the dimensions of the program's structure (e.g.

Abundance and Co-Distribution of Widespread Marine Archaeal Lineages in Surface Sediments of Freshwater Water Bodies across the Iberian Peninsula.

Archaea inhabiting marine and freshwater sediments have a relevant role in organic carbon mineralization, affecting carbon fluxes at a global scale. Despite current evidences suggesting that freshwater sediments largely contribute to this process, few large-scale surveys have been addressed to uncover archaeal diversity and abundance in freshwater sedimentary habitats. In this work, we quantified and high-throughput sequenced the archaeal 16S rRNA gene from surficial sediments collected in 21 inland waterbodies across the Iberian Peninsula differing in typology and trophic status.
