Multiomics dissection of human RAG deficiency reveals distinctive patterns of immune dysregulation but a common inflammatory signature.

Human recombination-activating gene (RAG) deficiency can manifest with distinct clinical and immunological phenotypes. By applying a multiomics approach to a large group of -mutated patients, we aimed at characterizing the immunopathology associated with each phenotype. Although defective T and B cell development is common to all phenotypes, patients with hypomorphic variants can generate T and B cells with signatures of immune dysregulation and produce autoantibodies to a broad range of self-antigens, including type I interferons.

Factors influencing workload and stress during resuscitation - A scoping review.

Aim: This scoping review aimed to identify potential variables influencing healthcare provider's perceived workload or stress when performing resuscitation on patients in cardiac arrest.

Methods: We searched Medline, EMBASE, PsycINFO, Cochrane, and Allied Health Literature (CINAHL) to identify studies published prior to February 1, 2024. We used a PECO format for this review: the population were healthcare providers performing resuscitation during simulated or real cardiac arrest; the exposure was the presence of any factor that could impact perceived workload or stress; and the comparator was the absence of any specific factor.

Characterization and functional analysis of type III polyketide synthases in Selaginella moellendorffii.

The evolutionary conservation of type III polyketide synthases (PKS) in Selaginella has been elucidated, and the critical amino acid residues of the anther-specific chalcone synthase-like enzyme (SmASCL) have been identified. Selaginella species are the oldest known vascular plants and a valuable resource for the study of metabolic evolution in land plants. Polyketides, especially flavonoids and sporopollenin precursors, are essential prerequisites for plant land colonization.
