Portulaca umbraticola, commonly known as "Eleven o'clock", is a popular ornamental plant in Brazil, but its potential as a non-conventional food source remains underexplored. Assessing its genetic and cytogenetic diversity is crucial for breeding and selecting optimal accessions. In this study, we analyzed the genetic diversity of P.

Comminuted fractures associated with tissue loss can adversely affect bone regeneration. Biomaterials enriched with mesenchymal stem cells (MSCs) employed for supporting osteosynthesis and potentiating osteoconduction are necessary to fill these bone defects. Natural compound biomaterials, similar to bone tissue, have been extensively tested in animal models for clinical use.

Yet there are no industry standards for comparing the performance of antibodies in various applications. We describe a knockout cell line-based antibody characterization platform, developed and approved jointly by industry and academic researchers, that enables the systematic comparison of antibody performance in western blot, immunoprecipitation and immunofluorescence.

Methods: Prospective, multinational, cohort study involving 15 hospitals that monitored preterm newborns to hospital discharge. Measures/exposures: maternal demographics; etiologically-based preterm birth sub-groups; very, moderate and late preterm categories, and feeding.
Article Synopsis
- A rare case of diprosopia, a condition with facial abnormalities, was observed in a blue shark embryo from the South Atlantic Ocean.
- The embryo had significant deformities, including two faces and a twisted spinal column, but most internal organs appeared normal upon microscopic analysis.
- This study marks the first documentation of internal organ morphology in a diprosopia specimen, suggesting that the embryo's survival may depend on its feeding ability and predator evasion skills post-birth.
