Comparison of the prevalence of calcidiol insufficiency in predialysis and osteoporotic populations
International Urology and Nephrology, 2008Calcidiol insufficiency is highly prevalent in chronic kidney disease (CKD) and osteoporotic patients. We assessed and compared calcidiol levels in these two groups from the same geographical area to differentiate environmental factors from characteristics related to CKD.We measured calcidiol levels in 160 predialysis (group 1) and 53 osteoporotic ...

The Journal of Steroid Biochemistry and Molecular Biology, 2005
Epidemiological studies suggest that serum calcidiol (25(OH)-Vitamin D3) seems to be associated with several cancers including prostate cancer. We have made several experimental studies in order to clarify the mechanism(s) involved in the association.

A synthesis of 17-epi-calcidiol
Tetrahedron Letters, 2004Abstract The first synthetic approach to 17- epi -calcidiol 4 and congeners is presented. Key steps of the synthesis involve Pd-catalyzed reaction of the androst-16-ene derivative 6 with alkyl diazoacetates producing the respective cyclopropane derivatives 5 , and lithium in liquid ammonia reduction of 5 leading to 17α-pregnane-20 ...

Intraocular calcidiol: Uncovering a role for vitamin D in the eye
The Journal of Steroid Biochemistry and Molecular Biology, 2020Vitamin D has emerged as a potentially important molecule in ophthalmology. To date, all ophthalmic data pertaining to vitamin D has been restricted primarily to tear and serum analysis in human patients. Considering the isolated nature of the eye, we sought to determine the presence of intraocular vitamin D in ocular disease.25-Hydroxyvitamin D3 (25 ...

Calcidiol and PTH Levels in Women Attending an Osteoporosis Program
Calcified Tissue International, 1999We performed a retrospective study of 237 patients attending a specialty osteoporosis practice. Secondary causes for reduced bone mineral density (BMD) were evaluated in 196 postmenopausal women and 41 premenopausal women; mean age was 56 +/- 13.8 years (mean +/- SD).
