Evolution of the umbilical cord blood proteome across gestational development.

Neonatal health is dependent on early risk stratification, diagnosis, and timely management of potentially devastating conditions, particularly in the setting of prematurity. Many of these conditions are poorly predicted in real-time by clinical data and current diagnostics. Umbilical cord blood may represent a novel source of molecular signatures that provides a window into the state of the fetus at birth.

Everolimus Through Plasmatic Concentrations in Cancer Patients: Prospective Longitudinal Observational Multicentric Study (DIANA-1 Project).

Everolimus, an oral inhibitor of the mammalian target of rapamycin (mTOR), is actually used to prevent organ transplant rejection and treat metastatic breast, renal, and neuroendocrine cancers. Despite significant pharmacokinetic variability among patients, routine therapeutic drug monitoring (TDM) is not commonly used in oncology. The aim of this multicenter, prospective observational cohort study is to assess the prevalence of everolimus minimum concentration at a steady state (Cminss) falling outside the therapeutic range (10-26.

Non-pharmaceutical interventions to combat COVID-19 in the Americas described through daily sub-national data.

This dataset covers national and subnational non-pharmaceutical interventions (NPI) to combat the COVID-19 pandemic in the Americas. Prior to the development of a vaccine, NPI were governments' primary tools to mitigate the spread of COVID-19. Variation in subnational responses to COVID-19 is high and is salient for health outcomes.

Ectopic callose deposition into woody biomass modulates the nano-architecture of macrofibrils.

Plant biomass plays an increasingly important role in the circular bioeconomy, replacing non-renewable fossil resources. Genetic engineering of this lignocellulosic biomass could benefit biorefinery transformation chains by lowering economic and technological barriers to industrial processing. However, previous efforts have mostly targeted the major constituents of woody biomass: cellulose, hemicellulose and lignin.

Putative pectate lyase PLL12 and callose deposition through polar CALS7 are necessary for long-distance phloem transport in Arabidopsis.

In plants, the phloem distributes photosynthetic products for metabolism and storage over long distances. It relies on specialized cells, the sieve elements, which are enucleated and interconnected through large so-called sieve pores in their adjoining cell walls. Reverse genetics identified PECTATE LYASE-LIKE 12 (PLL12) as critical for plant growth and development.
