Abnormal cleavage patterns in equine in vitro‐produced embryos lead to higher early pregnancy loss
Summary Background Despite significant advances, in vitro production (IVP) of equine embryos continues to lack standardised embryo classification criteria and is associated with increased rates of early pregnancy loss compared with in vivo‐derived blastocysts.

Fibril Structure of Desiccation‐Protective Tardigrade Protein CAHS‐8
We present the atomic structure of the fibril formed by an intrinsically disordered protein that has been shown to be responsible for remarkable environmental stress in tardigrades. X‐ray crystallography reveals a unique mechanism of fibril assembly whereby a single helix forms a stable, antiparallel coiled‐coil dimer, which then assembles into a ...

We characterize the PLTL lectin from Photorhabdus laumondii, which adopts a unique TNF‐like fold. Binding assays reveal a preference for branched histo‐blood group oligosaccharides. Protein crystallography uncovers a novel hexameric assembly and identifies key residues involved in carbohydrate recognition.

Development of alternative plant vitrification solutions in droplet-vitrification procedures.
This study aimed at developing alternative vitrification solutions, modified either from the original PVS2 vitrification solution by increasing glycerol and sucrose and/or decreasing dimethylsulfoxide and ethylene glycol concentration, or from the original PVS3 vitrification solution by decreasing glycerol and sucrose concentration.

Electron microscopy‐based three‐dimensional subcellular imaging of plant male gametophyte
The Aquilos2 Cryo‐FIB workflows provide practical routes for cryo‐electron tomography and volume imaging in plant structural biology. ABSTRACT Understanding cellular events in three dimensions (3D) is of great importance for the annotation and illustration of biological processes in a contextual way. Imaging techniques based on electron microscopy (EM),

Precisely synthesized hexabrominated [9]cycloparaphenylene (CPP), accessed by a gold‐mediated method, enables efficient multisite post‐functionalization through cross‐coupling reactions. Late‐stage π‐extension on the CPP framework successfully affords armchair‐type chiral nanohoops exhibiting strong circularly polarized luminescence (|glum| = 0.100 ...

Summary Duckweeds (Lemnaceae) have excellent potential for fundamental and applied research due to ease of cultivation, small size, and continuous fast clonal growth. However, their usage as model organisms and platforms for biotechnological applications is often limited by the lack of universal genetic manipulation methods necessary for transgene ...

Ultrastructure of astrocytes using volume electron microscopy: A scoping review
Abstract figure legend A complete overview on astrocyte ultrastructure with volume electron microscopy. The morphology of astrocytes under physiological and pathological conditions plays a role in brain homeostasis, synaptic activity and structural support, but their morphological complexity and heterogeneity are still poorly quantified.

Predictive Model for Epoxy‐Amine Polymerizations at Decreased Tc Using Variable Frequency Microwaves
Two‐way interaction of basicity and entropy. ABSTRACT This study presents a predictive model for the thermo‐mechanical properties of epoxy polymers cured with Variable Frequency Microwave (VFM) processing. The model is based on properties derived from the structural features of the epoxide and amine precursors.
