Noxious Somatic Inputs to Hypothalamic-Midbrain Projection Neurones: a Comparison of the Columnar Organisation of Somatic and Visceral Inputs to the Periaqueductal Grey in the Rat

EXPERIMENTAL PHYSIOLOGY, Issue 2 2002
D. M. Parry
The induction of Fos protein was used to localise hypothalamic neurones activated by noxious somatic stimulation. This was combined with retrograde transport of fluorescent latex microspheres from identified ,pressor' and ,depressor' sites in the dorsolateral/lateral or ventrolateral columns of the periaqueductal grey (PAG). Fos-positive neurones were found throughout the rostral hypothalamus. Of those neurones activated by noxious somatic stimuli that projected to the PAG all but one was retrogradely labelled from sites that included the lateral column. Only one neurone was double labelled following injection of tracer at a depressor site in the ventrolateral PAG. This is in marked contrast to visceroresponsive hypothalamic neurones, a larger proportion of which project to the PAG and which, as reported previously, preferentially target depressor sites in the ventrolateral sector. These results are discussed in relation to the roles of the anterior hypothalamus and the different functional columns of the PAG in co-ordinating autonomic and sensory functions in response to nociceptive inputs originating in different peripheral domains.

Earliest complete hominin fifth metatarsal,Implications for the evolution of the lateral column of the foot

AMERICAN JOURNAL OF PHYSICAL ANTHROPOLOGY, Issue 3 2009
Bernhard Zipfel
Abstract StW 114/115, from Sterkfontein, South Africa, is the earliest complete hominin fifth metatarsal. Comparisons of StW 114/115 to modern humans, extant apes, and partial hominin metatarsals AL 333-13, AL 333-78, SKX 33380, OH 8, and KNM-ER 803f reveal a similar morphology in all six fossils consistent with habitual bipedality. Although StW 114/115 possesses some primitive characters, the proximal articular morphology and internal torsion of the head are very human-like, suggesting a stable lateral column and the likely presence of lateral longitudinal and transverse tarsal arches. We conclude that, at least in the lateral component of the foot of the StW 114/115 individual, the biomechanical pattern is very similar to that of modern humans. This, however, may not have been the case in the medial column of the foot, as a mosaic pattern of hominin foot evolution and function has been suggested. The results of this study may support the hypothesis of an increased calcaneo-cuboid stability having been an early evolutionary event in the history of terrestrial bipedalism.

Subacute Combined Degeneration Due to Copper Deficiency

JOURNAL OF NEUROIMAGING, Issue 4 2007
Joseph M. Ferrara MD
ABSTRACT There is growing clinical evidence supporting a connection between copper deficiency and subacute combined degeneration. While nearly half of patients with copper deficiency myelopathy exhibit MRI abnormalities, signal changes are often ill-defined in distribution. We report a patient with sensory ataxia and spastic paraplegia from copper deficiency whose MRI demonstrates abnormal signal restricted to the dorsal and lateral columns, providing clear radiological support of an association between hypocupremia and combined system degeneration.

Set in stone: monumental altar frames in Renaissance Florence

RENAISSANCE STUDIES, Issue 1 2010
Meghan Callahan
In 1864 the V&A (then the South Kensington Museum) purchased a large marble altar frame from a dealer in Florence. The quality of the frame identifies it as the product of a leading Florentine sculpture workshop, possibly that of Giuliano da Sangallo at the end of the fifteenth century. Its dimensions indicate that it would have housed a large altarpiece in one of the city's churches. The frame's provenance remains obscure, but this article offers the first critical evaluation of the object based on first-hand examination. Comparisons with similar frames in Florentine churches (surviving and documented) suggest that the V&A frame can be identified as an example of a particular category of monumental altar that was popular in the city in the decades around 1500. This type combined painted panel altarpieces with sculpture, integrating both within impressive architectural superstructures comprising lateral columns, elaborate entablatures, and arched lunettes. Identifiable examples housed altarpieces by Perugino, Lorenzo di Credi, Piero di Cosimo, and Ridolfo del Ghirlandaio, each juxtaposed with tin-glazed terracotta reliefs by the Della Robbia shop. The popularity of these arched frames was relatively short-lived, but their brief heyday provides important evidence for the gathering appreciation of aesthetic integration, formal order and spatial symmetry within Italian church interiors in the years around 1500.
