New, puzzling insights from comparative myological studies on the old and unsolved forelimb/hindlimb enigma

open access: yesBiological Reviews of The Cambridge Philosophical Society, 2013
Most textbooks and research reports state that the structures of the tetrapod forelimbs and hindlimbs are serial homologues. From this view, the main challenge of evolutionary biologists is not to explain the similarity between tetrapod limbs, but ...

Getting back on your hindlimbs [PDF]

open access: yesNature Reviews Neuroscience, 2018
A combination of electrochemical neuromodulation of spinal leg circuits and physical training in a robotic rehabilitation system restored volitional locomotion in rodents with severe spinal cord injury.

Morphology and function of pinniped necks: The long and short of it

open access: yesThe Anatomical Record, EarlyView.
Abstract Terrestrial vertebrates from at least 30 distinct lineages in both extinct and extant clades have returned to aquatic environments. With these transitions came numerous morphological adaptations to accommodate life in water. Relatively little attention has been paid to the cervical region when tracking this transition.

The morphology of the oval window in Paranthropus robustus compared to humans and other modern primates

open access: yesThe Anatomical Record, EarlyView.
Abstract The oval window (OW) is an opening connecting the inner and middle ear. Its area has been shown to consistently scale with body mass (BM) in primates, and has been used alongside semi‐circular canal (SCC) size to differentiate Homo sapiens and fossil hominins, including Paranthropus robustus.

Omega-3 Fatty Acids Improve Recovery, whereas Omega-6 Fatty Acids Worsen Outcome, after Spinal Cord Injury in the Adult Rat [PDF]

open access: yes, 2006
Spinal cord injury (SCI) is a cause of major neurological disability, and no satisfactory treatment is currently available. Evidence suggests that polyunsaturated fatty acids (PUFAs) could target some of the pathological mechanisms that underlie damage ...

Technological Innovations and Applications of Spatial Transcriptomics in Livestock and Poultry Research

open access: yesAnimal Research and One Health, EarlyView.
The paper is divided into three main sections: a review of the development of spatial transcriptomics technology, its applications in livestock and poultry research, and its future prospects. This article provides an overview of the current state of spatial transcriptomics in animal research, exploring its integration with multiomics technologies as ...

Hand and foot pressures in the aye-aye (Daubentonia madagascariensis) reveal novel biomechanical trade-offs required for walking on gracile digits [PDF]

open access: yes, 2010
Arboreal animals with prehensile hands must balance the complex demands of bone strength, grasping and manipulation. An informative example of this problem is that of the aye-aye (Daubentonia madagascariensis), a rare lemuriform primate that is unusual ...

The Link Between TGF‐β Signaling and Chromatin Dynamics Takes an Unexpected Path

open access: yesBioEssays, EarlyView.
A recent study uncovered a novel mechanism by which Tgfbr1 regulates morphogenesis: not by directly controlling the expression of genes regulating cell fate but by globally modulating chromatin accessibility, thus determining which enhancers are available to other morphogenetic factors, ultimately enabling the activation of specific developmental ...

Monocyte activation in angiogenesis and collateral growth in the rabbit hindlimb.

open access: yesJournal of Clinical Investigation, 1998
We have previously shown that monocytes adhere to the vascular wall during collateral vessel growth (arteriogenesis) and capillary sprouting (angiogenesis).

A Persistent Hindlimb Ischemia Model in the Rabbit

open access: yesJournal of Investigative Surgery, 1994
The study of new approaches for the treatment of limb-threatening ischemia has been hampered by the lack of a suitable animal model of persistent limb ischemia. We describe the development and evaluation of an animal model of persistent hindlimb ischemia, in which ischemia was induced in the left hindlimb of 28 rabbits by ligation of the distal ...
