Not only are they the site of conversion of 7-dehydrocholesterol (7DHC) to vitamin D3 following UVB-radiation [2], [4], [5], but they also express enzymes to hydroxylate vitamin D3 to the hormonally active form known as calcitriol or 1,25-dihydroxyvitamin D3 (1,25(OH)2D3).
Conversion of 25-hydroxyvitamin D (25(OH D) to 1,25-dihydroxyvitamin D (1,25(OH)2D), the active vitamin D metabolite, occurs in the endometrium (11, 12), although the main site of conversion is the kidney (4).
From these observations, we can infer the sites of conversion of PrPc to PrPd and the inter and intracellular trafficking of PrPd in two strains of sheep scrapie.
It happened also to be the site of his conversion to chuting, fourteen years earlier.
Marijanovic, Z., Caputo, A., Campana, V. & Zurzolo, C. Identification of an intracellular site of prion conversion.
The site of the Conversion of Paul was traditionally identified with the small village of Kokab, north-east of Quneitra, on the road to Damascus.
Since the cell surface is a possible site of the conversion of PrPC to PrPSc [12], [13] the effect of glimepiride on the PrPSc content of ScGT1 cells was determined.
Placental accumulation of PrPSc in sheep is limited by the effect of fetal genotype [ 9, 32, 33] because the fetal trophoblast is a major site of PrPSc conversion or accumulation in the placenta.
The unstructured nature of this region has led some investigators to consider this stretch of residues as a potential nucleation site for conversion of PrPsen to PrPres (37 ).
New York has also been the site of numerous conversions (the famed Plaza hotel will close this spring, and reopen in 2006 with more condos than hotel rooms), as have cities such as Philadelphia and Washington, D.C., where the old Columbia Women's Hospital is being turned into the Columbia, a high-priced condo development.
However, as the experiment proceeds an improvement on the corrosion behaviour of the sample was observed, which was interpreted on the basis of self-healing properties of the Ce conversion layer as well as on the blocking of the defective sites of the conversion coating by corrosion products.
