Covalent Immobilisation of PVA‐MA Hydrogels on Plasma‐Activated Coatings: Achieving Superior Adhesion by Reagent‐Free Formation of a Nanoscale Primer Layer

Advanced NanoBiomed Research, EarlyView.
Robust attachment of hydrogels to solid substrates is critical to success in cell culture where hydrostatic and contractile forces can contribute to delamination of weakly adhered gels. This novel approach forms a nanometer‐scale, reagent‐free hydrogel primer layer to provide improved resistance to delamination of subsequent bulk hydrogel layers in a ...

Catalysis by a Metastable Photoswitchable Cage

Angewandte Chemie International Edition, EarlyView.
A self‐assembled heteroleptic cage is formed by isomerizing a photoswitchable ligand to its metastable Z‐isomeric form (Z‐1) using green light and combining with a non‐switchable ligand (2) and palladium(II) ions. The metastable [Pd2(Z‐1)2(2)2]4+ cage is an out‐of‐equilibrium self‐assembled catalyst, and can be reversibly assembled and disassembled ...

Cortical bone distribution in the human mandibular symphysis: Ontogenic and morphometric approaches in archeological context

The Anatomical Record, EarlyView.
Abstract The human mandibular symphysis concentrates multiaxial loads during function and remodels throughout growth, but the precise mechanisms underlying cortical bone shape during growth remain relatively unexplored. Approaches based solely on thickness or external cortical contours provide only partial insights and do not capture the functional ...

MicroCT reinvestigation of the only articulated fossil anostomid fish reveals synonymy of Arhinolemur Ameghino, 1898 and Megaleporinus Ramirez et al., 2017

The Anatomical Record, EarlyView.
Abstract Arhinolemur scalabrinii† Ameghino, 1898 was originally described as a strepsirrhine primate (Mammalia) but has been recognized as an anostomid fish since 2012. It remains the only extinct anostomid species known from complete cranial material.

Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny

The Anatomical Record, EarlyView.
Abstract Cynodontia is an important subclade of Therapsida that first occurred in the late Permian. It includes extinct subclades which are the non‐mammaliaform cynodonts and Mammaliaformes, with the latter ultimately giving rise to crown mammals. The systematics of non‐mammaliaform cynodonts has been extensively studied and is relatively well‐resolved,

Proximal Contact Status and Its Association with Caries and Food Impaction in Teeth Adjacent to Fixed Prostheses: A Cross-Sectional Study

Bangladesh Journal of Dental Research & Education
Background: The longevity of fixed prostheses (FPDs) depends on ideal interproximal contacts between adjacent natural teeth or dental restorations. Although the proximal contact status (PCS) is a known determinant of periodontal health, scant data is ...
