Role of soft tissue and bone interactions in the developmental integration and modularity of the skull in neural crest‐specific gap junction alpha‐1 knockout mice

The Anatomical Record, EarlyView.
Abstract The vertebrate skull is composed of bones derived from neural crest cells and mesoderm. The evolutionary capacity of the skull has been linked, in part, to the emergence of neural crest cells; however, this increased capacity for evolutionary change requires that variation within neural crest‐ and mesoderm‐derived bones remains partly ...

Clade‐wide morphological and functional variation of the sauropsid columella

The Anatomical Record, EarlyView.
Abstract The columella (=stapes) is the middle ear bone of reptiles that transmits vibrations from the environment to the inner ear. It has been shown to exhibit extensive interspecific morphological disparity in several clades; however, its morphological variation and associated functional consequences remain poorly described.

Arthroscopy‐Assisted Fixation of Combined Coracoid Fracture and Acromioclavicular Dislocation: A Minimalist Approach

Arthroscopy Techniques, EarlyView.
Abstract Combined acromioclavicular dislocation and coracoid process fracture disrupts the superior shoulder suspensory complex, leading to shoulder instability that often requires surgical intervention. This rare injury, increasingly identified through advanced diagnostics, lacks consensus on the optimal treatment. We describe a minimalist arthroscopy‐

Transtibial Anterior Cruciate Ligament Reconstruction Using a Synthetic Graft Combined With Remnant Repair: A Hybrid Technique

Arthroscopy Techniques, EarlyView.
Abstract The purpose of this technical note is to describe a hybrid arthroscopic technique that combines anterior cruciate ligament reconstruction using a synthetic graft with concomitant remnant repair. Following diagnostic arthroscopy and assessment of remnant quality, tibial and femoral tunnels are created using a transtibial approach with attention

Microbiome and aging: Trajectories of microbiome age across human ecosystems and their systemic effects

iMeta, EarlyView.
Microbiome age (MA) has emerged as an innovative biomarker of biological aging, reflecting host aging trajectories through dynamic alterations in microbial composition, function, and host–microbe interactions across multiple body ecosystems. Diverse computational strategies—including traditional machine learning, deep learning, and multi‐omics ...

A Coarse Geometric Approach to Graph Layout Problems

Journal of Graph Theory, EarlyView.
ABSTRACT We define a range of new coarse geometric invariants based on various graph–theoretic measures of complexity for finite graphs, including treewidth, pathwidth, cutwidth and bandwidth. We prove that, for bounded degree graphs, these invariants can be used to define functions which satisfy a strong monotonicity property, namely, they are ...

Stable Cuts, NAC‐Colourings and Flexible Realisations of Graphs

Journal of Graph Theory, EarlyView.
ABSTRACT A (2‐dimensional) realisation of a graph G $G$ is a pair ( G , p ) $(G,p)$, where p $p$ maps the vertices of G $G$ to R 2 ${{\mathbb{R}}}^{2}$. A realisation is flexible if it can be continuously deformed while keeping the edge lengths fixed, and rigid otherwise.

A single intra‐articular stromal vascular fraction with platelet‐rich plasma injection yields superior clinical outcomes than a hyaluronic acid injection in patients with knee osteoarthritis: A prospective comparative study

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose The present study aimed to compare the efficacy and safety of a combined injection of stromal vascular fraction (SVF) and platelet rich plasma (PRP) versus a high molecular weight (HMW) hyaluronic acid (HA) injection in patients with knee osteoarthritis (KOA).

Kuga–Satake Construction on Families of K3 Surfaces of Picard Rank 14

Mathematische Nachrichten, EarlyView.
ABSTRACT The isometry between the type IV6 and the type II4 hermitian symmetric domains suggests a possible relation between suitable moduli spaces of K3 surfaces of Picard rank 14 and of polarized abelian 8‐folds with totally definite quaternion multiplication. We show how this isometry induces a geometrically meaningful map between such moduli spaces

Amenability Constants for Unconditional Sums of Banach Algebras

Mathematische Nachrichten, EarlyView.
ABSTRACT We study Johnson amenability for unconditional direct sums of Banach algebras. Given a family (Ai)i∈I$(A_i)_{i\in I}$ of Banach algebras and a Banach sequence lattice E$E$ on I$I$, the E$E$‐sum ⨁i∈IAiE${\bigl (\bigoplus _{i\in I} A_i\bigr)}_{\!E}$ carries a natural Banach algebra structure via coordinatewise multiplication.
