Betaine lipids overproduced in seed plants are excluded from plastid membranes and promote endomembrane expansion.

Plants and algae have to adapt to environmental changes and face various stresses that negatively affect their growth and development. One common stress is phosphate (Pi) deficiency, which is often present in the environment at limiting levels. In response to Pi deficiency, these organisms increase Pi uptake and remobilize intracellular Pi.

Clinical and functional assessment of SARS-CoV-2 sequelae among young marines - a panel study.

Background: Long-term SARS-CoV-2 adverse health outcomes are of significant concern, especially among young adults with the potential for the greatest long-term morbidity. We sought to assess and characterize these outcomes in a cohort of Marines.

Methods: We used a cohort of US Marines from a previous longitudinal, prospective observational study of acute SARS-CoV-2, most of whom were enrolled prior to infection.

Monogalactosyldiacylglycerol synthase isoforms play diverse roles inside and outside the diatom plastid.

Diatoms derive from a secondary endosymbiosis event, which occurred when a eukaryotic host cell engulfed a red alga. This led to the formation of a complex plastid enclosed by four membranes: two innermost membranes originating from the red alga chloroplast envelope, and two additional peri- and epiplastidial membranes (PPM, EpM). The EpM is linked to the endoplasmic reticulum (ER).

COVID-19 inpatient care performance in the unified health system, São Paulo state, Brazil: an application of standardized mortality ratio for hospitals' comparisons : COVID-19 inpatient care performance in SUS, Brazil.

Objective: To evaluate the variation in COVID-19 inpatient care mortality among hospitals reimbursed by the Unified Health System (SUS) in the first two years of the pandemic in São Paulo state and make performance comparisons within periods and over time.

Methods: Observational study based on secondary data from the Hospital Information System. The study universe consisted of 289,005 adult hospitalizations whose primary diagnosis was COVID-19 in five periods from 2020 to 2022.

Linking meta-learning to meta-structure.

We propose that a principled understanding of meta-learning, as aimed for by the authors, benefits from linking the focus on learning with an equally strong focus on structure, which means to address the question: What are the meta-structures that can guide meta-learning?
