Modern survivors of previously more diverse lineages are regarded as living fossils, particularly when characterized by morphological stasis. Cycads are often cited as a classic example, reaching… (More)
Longitudinal chromatic aberration of the eye (LCA) produces "color fringes" at edges that specify focus. Fincham [(1951) British Journal of Ophthalmology, 35, 381-393] concluded that these chromatic… (More)
Phylogenetic analyses of partial phytochrome B (PHYB) nuclear DNA sequences provide unambiguous resolution of evolutionary relationships within Poaceae. Analysis of PHYB nucleotides from 51 taxa… (More)
We have investigated the spatiotemporal transfer function of human "reflex" accommodation. An accommodative mechanism that is sensitive to an intermediate temporal rate of retinal image contrast… (More)
Autosomal dominant familial partial lipodystrophy (FPLD) due to mutant LMNA encoding nuclear lamin A/C is characterized by adipose tissue repartitioning together with multiple metabolic disturbances,… (More)
The isolation of a novel complementary DNA (cDNA) clone coding for human calmodulin (CaM) is reported. Although it encodes a protein indistinguishable from the only known higher vertebrate… (More)
Previous studies have suggested that targets illuminated by monochromatic (narrow-band) light are less effective in stimulating the eye to change its focus than are black-white (broadband) targets.… (More)
OBJECTIVES
  Chitosan is widely used as a scaffold for bone tissue engineering. However, up-to-date, no previous detailed study has been conducted to elucidate any mechanism of osteogenesis by… (More)
Fetuin inhibits insulin-induced insulin receptor (IR) autophosphorylation and tyrosine kinase activity in vitro, in intact cells, and in vivo. The fetuin gene (AHSG) is located on human chromosome… (More)
