Optimizing data collection for obstetrical ultrasound research at the primary health care level in rural Uganda.

Background: Neonatal and maternal mortality remains high in low- and middle-income countries (LMIC), especially in sub-Saharan Africa. Quality data collection is crucial to understand the magnitude of these problems and to measure the impact of interventions aimed at improving neonatal and maternal mortality. However, data collection in the low-income country setting, especially in rural areas, has been a challenge for researchers, policy makers, and public health officials.

High quality MAGs from lignocellulose-impacted environments elucidate metabolism and evolutionary mechanisms.

The archaeal class is widely and abundantly distributed in anoxic habitats. Metagenomic studies have suggested that they are mixotrophic, capable of CO fixation and heterotrophic growth, and involved in acetogenesis and lignin degradation. We analyzed 35 metagenome-assembled genomes (MAGs), including the first complete circularized MAG (cMAG) of the Bathy-6 subgroup, from the metagenomes of three full-scale pulp and paper mill anaerobic digesters and three laboratory methanogenic enrichment cultures maintained on pre-treated poplar.

Resolving the contrasting leaf hydraulic adaptation of C and C grasses.

Grasses are exceptionally productive, yet their hydraulic adaptation is paradoxical. Among C grasses, a high photosynthetic rate (A) may depend on higher vein density (D) and hydraulic conductance (K). However, the higher D of C grasses suggests a hydraulic surplus, given their reduced need for high K resulting from lower stomatal conductance (g).
