The osteoporosis was common complication of ankylosing spondylitis (AS), but it was frequently unrecognized in the initial stage of the disease. This study was to compare areal bone mineral density (BMD) of hip joints in early AS patients with that in healthy controls, to explore the progress of bone loss in cortex and spongiosa in early AS.Quantitative computed tomography (QCT) of hip was performed in 60 AS patients (modified New York criteria for AS, with grade 2 sacroiliitis in computed tomography) and 57 healthy controls.

Article Synopsis
- Ergosterol is a key component of yeast membranes, affecting fluidity and permeability, and is also important for vitamin D2 production.
- The ERG5 gene encodes an enzyme essential for the formation of a double bond in the ergosterol biosynthesis pathway and was cloned and over-expressed in yeast for study.
- The study involved amplifying the ERG5 gene, creating a recombinant plasmid for expression, and comparing sterol profiles of yeast strains to see the effects of ERG5 over-expression on ergosterol production.
