Intramolecular Phenyl Transfer from Boron to Lithium, Sodium, and Copper: Defining the Limits of Transmetalation

open access: yesHelvetica Chimica Acta, EarlyView.
Abstract Transmetalation is a key elementary step in organometallic chemistry, for which reason there is a keen interest in better understanding the factors governing this reaction. We have previously reported the unusual transfer of a phenyl anion from boron to lithium in the gas‐phase dissociation of [LiBr(tBu)(Ph)Bpin]− (Chem. Eur. J.

Potential Spectral Tuning of the Tapetum Lucidum in a Broadly Distributed Ungulate

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT The tapetum lucidum, a biological reflector system found in the eyes of many vertebrate species, enhances visual sensitivity in low light conditions by reflecting light back through the retina. The structure of the ungulate tapetum fibrosum is unique, and its reflectance varies temporally in reindeer (Rangifer tarandus).

Multi‐Scale Analysis of Regional Pathology in the Human Trapezium During Osteoarthritis Progression

open access: yesJournal of Orthopaedic Research, EarlyView.
ABSTRACT Trapeziometacarpal (TMC) osteoarthritis (OA) is a prevalent condition that significantly impacts hand function and quality of life. In this study we sought to close gaps in knowledge related to the initiation and progression of TMC OA on the tissue scale by evaluating the morphology and gross appearance, wear patterns, mechanical properties ...

Impaired physical fitness in pediatric inflammatory bowel disease

open access: yesJournal of Pediatric Gastroenterology and Nutrition, EarlyView.
Abstract Objective There are only a few studies on physical fitness in pediatric inflammatory bowel disease (PIBD). We compared physical fitness in PIBD patients versus healthy controls and analyzed the role of contributing disease‐ and patient‐related factors.
