The nanoscale microstructure and chemistry of a transparent gahnite glass-ceramic its precursor glass were investigated using atom probe tomography, transmission electron microscopy, nuclear magnetic resonance spectroscopy. In the annealed glass, statistically significant ZrO clustering was observed along with Si depletion within 2 nm clusters. This is expected to be first step in nucleation cr...

Angiotensin-converting enzyme (ACE) and the Alzheimer’s disease amyloid precursor protein are two examples of membrane-bound proteins that are released in a soluble form by a post-translational proteolytic cleavage event involving a secretase. Site-specific antibodies and matrixassisted laser desorption ionization-time-of-flight (‘MALDI-TOF ’) MS have been used to map the secretase cleavage sit...

We have constructed a cDNA library from the mRNA of a rat liver cell line (BRL-3A) and characterized cDNA clones encoding the protein precursor of the rat insulin-like growth factor II (pre-pro-rIGF-II). This precursor, inferred from the nucleotide sequence, consists of a signal peptide, the rIGF-II sequence, and a trailer polypeptide of unknown significance. The characterized cDNA sequence (10...

Objective To investigate the effects of repetitive peripheral magnetic stimulation (rPMS) on the vastus lateralis (VL) in the early stage after hip replacement surgery. Methods Twenty-two patients who underwent hip replacement after proximal femur fracture were included in this study. After hip surgery, the experimental group was applied with 15 sessions of 10 Hz rPMS over the VL 5 times per ...

INTRODUCTION Both conservative and operative management have been described in the literature for the management of chronic Achilles tendon ruptures with surgical management generally having more favourable results. In our institution, the favoured reconstructive technique was the use of 2 turndown tendon fl aps fashioned from the proximal Achilles tendon augmented by a tenomyodesis of the flex...

Progenitor cells capable of giving rise to functional macrophages in in vitro culture were first detectable in the fetal yolk sac of the mouse between day 7 and 8 of gestation. Macrophage progenitors were not detectable outside the yolk sac until day 11. Although the early yolk sac contained macrophage precursors, no cells with the morphologic or functional characteristics of mouse promonocytes...

PURPOSE To determine whether bovine retinal endothelial cells (BRECs) bind, synthesize, and respond to vasculotropin-vascular endothelial growth factor (VAS-VEGF). METHODS Cultured BRECs were tested for their ability to bind 125I VAS-VEGF and their response to the growth and migration-promoting effect of VAS-VEGF. Total RNAs extracted from BRECs were reverse transcribed and amplified by polym...
