Challenging the idea of the inner nuclear membrane (INM) being an inert compartment, recent work in S. cerevisiae shows that the INM can metabolize lipids and that local lipid metabolism can regulate transcription in response to lipid availability, suggesting a functional role for the INM in cellular lipid homeostasis.

Protoderm formation is a crucial step in early embryo patterning in plants, separating the precursors of the epidermis and the inner tissues. Although key regulators such as ARABIDOPSIS THALIANA MERISTEM LAYER1 (ATML1) and PROTODERMAL FACTOR2 (PDF2) have been identified in the model plant Arabidopsis thaliana, the genetic pathways controlling protoderm specification remain largely unexplored. Here, we combined genetic, cytological, and molecular approaches to investigate the regulatory mechanisms of protoderm specification in Arabidopsis thaliana.

Nuclear pore complexes (NPCs) act as gateways across the nuclear envelope for molecular transport between the nucleus and the cytoplasm in eukaryotes. NPCs consist of several subcomplexes formed by multiple copies of approximately 30 different proteins known as nucleoporins (Nups). In the fission yeast Schizosaccharomyces pombe, the NPC structure is unique, particularly in its outer ring subcomplexes, where the cytoplasmic and nucleoplasmic outer rings are composed of distinct sets of proteins.

Objectives: Gadopiclenol is a q = 2 pyclen gadolinium-based contrast agent (GBCA) recently approved by the Food and Drug Administration, European Medicines Agency, and other European countries. The aim of this report is to demonstrate its stability in multiple stressed in vitro conditions and in vivo, in rat kidney, while maintaining its higher relaxivity compared with conventional GBCAs on the market.
Materials And Methods: Both gadopiclenol and its chemical precursor Pi828-Gd were characterized and compared with q = 1 gadolinium (Gd) complexes.

Oxygen vacancies in Ruddlesden-Popper (RP) perovskites (PV) [AO][ABO] play a pivotal role in engineering functional properties and thus understanding the relationship between oxygen-vacancy distribution and physical properties can open up new strategies for fine manipulation of structure-driven functionalities. However, the structural origin of preferential distribution for oxygen vacancies in RP structures is not well understood, notably in the single-layer ( = 1) RP-structure. Herein, the = 1 RP phase SrNdZnO was rationally designed and structurally characterized by combining three-dimensional (3D) electron diffraction and neutron powder diffraction.

Fish with unique life cycles offer valuable insights into retinal plasticity, revealing mechanisms of environmental adaptation, cell proliferation, and thus, potentially regeneration. The variability of the environmental factors to which Austrolebias annual fishes are exposed has acted as a strong selective pressure shaping traits such as nervous system plasticity. This has contributed to adaptation to their extreme conditions including the decreased luminosity as ponds dry out.
