Green microalga conserves substrate uptake pattern but changes their metabolic uses across trophic transition.

The terrestrial green alga is an emerging model species with potential applications including production of triacylglycerol or astaxanthin. How interacts with the diverse substrates during trophic transitions is unknown. To characterize its substrate utilization and secretion dynamics, we cultivated the alga in a soil-based defined medium in transition between conditions with and without glucose supplementation.

Iron rescues glucose-mediated photosynthesis repression during lipid accumulation in the green alga Chromochloris zofingiensis.

Energy status and nutrients regulate photosynthetic protein expression. The unicellular green alga Chromochloris zofingiensis switches off photosynthesis in the presence of exogenous glucose (+Glc) in a process that depends on hexokinase (HXK1). Here, we show that this response requires that cells lack sufficient iron (-Fe).

Postoperative Patient Portal Messaging Is Associated With Return to the Emergency Department After Lumbar Spine Surgery.

Study Design: Retrospective study.

Objective: To explore the association between patients undergoing lumbar spine surgery who message their care team via an electronic patient portal (EPP) postoperatively and emergency department (ED) visits within 90 days of surgery.

Summary Of Background Data: Secure patient messaging through electronic patient portals has grown over recent years.

Phylogenetically diverse wild plant species use common biochemical strategies to thrive in the Atacama Desert.

The best ideotypes are under mounting pressure due to increased aridity. Understanding the conserved molecular mechanisms that evolve in wild plants adapted to harsh environments is crucial in developing new strategies for agriculture. Yet our knowledge of such mechanisms in wild species is scant.

Hospital Discharge Planners Need More Information When Referring Patients to Home Health Care: Insights From the Coronavirus Disease 2019 Pandemic.

Hospital discharge planners play an important role in helping patients choose appropriate home health care. However, during the COVID-19 pandemic, they may not have had enough information to make the best decisions for their patients. A study of 58 discharge planners from Michigan hospitals found that 90% of them wanted information about the quality of home health agencies and whether they were prepared for COVID-19.
