Ectodermal Wnt signaling, cell fate determination, and polarity of the skate gill arch skeleton.
The gill skeleton of cartilaginous fishes (sharks, skates, rays, and holocephalans) exhibits a striking anterior-posterior polarity, with a series of fine appendages called branchial rays projecting from the posterior margin of...
Effect of Increased Salinity Concentrations on Gill Morphology and Gene Expression in Redear Sunfish (Lepomis microlophus)
Joel Haley
Jan 01, 0001
Changes in gill morphology have been observed in certain species of freshwater fish in response to increases in salinity. The purpose of this study was to observe the salinity tolerance and the osmoregulatory responses through...

Developmental evidence for serial homology of the vertebrate jaw and gill arch skeleton.
Gegenbaur's classical hypothesis of jaw-gill arch serial homology is widely cited, but remains unsupported by either palaeontological evidence (for example, a series of fossils reflecting the stepwise transformation of a gill...
The evolution of mendelian randomization for investigating drug effects.
Dipender Gill and Stephen Burgess discuss the accompanying study by James Yarmolinsky and colleagues investigating the associations between genetically-proxied inhibition of antihypertensive drug targets and risk of common...
Gill developmental program in the teleost mandibular arch.
Whereas no known living vertebrate possesses gills derived from the jaw-forming mandibular arch, it has been proposed that the jaw arose through modifications of an ancestral mandibular gill. Here, we show that the zebrafish...

Embryonic origin and serial homology of gill arches and paired fins in the skate, Leucoraja erinacea
Paired fins are a defining feature of the jawed vertebrate body plan, but their evolutionary origin remains unresolved. Gegenbaur proposed that paired fins evolved as gill arch serial homologues, but this hypothesis is now...

Palladium-catalysed C-H activation of aliphatic amines to give strained nitrogen heterocycles.
The development of new chemical transformations based on catalytic functionalization of unactivated C-H bonds has the potential to simplify the synthesis of complex molecules dramatically. Transition metal catalysis has emerged...
Enantioselective Intermolecular C-H Amination Directed by a Chiral Cation.
The enantioselective amination of C(sp3)-H bonds is a powerful synthetic transformation yet highly challenging to achieve in an intermolecular sense. We have developed a family of anionic variants of the...
