Novel variant in ACTA1 identified in a fetus with akinesia deformation sequence and cortical development delay.

We present a case of fetal akinesia deformation sequence due to nemaline myopathy (NM). In addition to the muscle manifestations, prenatal observations included an enlarged subarachnoid space and delayed cortical development. Trio whole-exome sequencing revealed a de novo novel pathogenic variant in the ACTA1 gene, which encodes skeletal muscle alpha-actin.

Recent Advances in Bioelectrochemical Systems for Nitrogen and Phosphorus Recovery Using Membranes.

Bioelectrochemical systems (BESs) have emerged as a technology that is able to recover resources from different kinds of substrates, especially wastewater. Nutrient recovery, mostly based on membrane reactor configuration, is a clear niche for BES application. The recovery of nitrogen or phosphorus allows for treatment of wastewater while simultaneously collecting a concentrated stream with nutrients that can be reintroduced into the system, becoming a circular economy solution.

Closing nutrient loops in a maize rotation. Catch crops to reduce nutrient leaching and increase biogas production by anaerobic co-digestion with dairy manure.

Three catch crop species, ryegrass, forage rape and black oat, were grown between successive rotations of maize to reduce nitrogen leaching due to maize fertilization with digested dairy manure. Catch crops showed a high nutrient uptake, but with a wide range, depending on the year and the specie. Ensiling was shown to be a feasible storing method increasing catch crop methane production per hectare between 14-36% compared with fresh catch crop.

Autoimmune hemolytic anemia in pregnancy: a challenge for maternal and fetal follow-up.

Background: Autoimmune hemolytic anemia (AIHA) is a rare entity during pregnancy. The fetal risk is determined primarily by the ability of autoantibodies to cross the placental barrier. Currently, the establishment of a standardized antenatal care in cases with AIHA remains as a pending issue.
