BACKGROUND Benign paroxysmal positional vertigo (BPPV) is a condition with recurrent attacks in a significant proportion of patients. The present case- control study was conducted to assess the influence of serum vitamin D normalization on recurrent attacks of vitamin D deficient patients. METHODS Diagnosis of BPPV was made based on history and clinical examination and exclusion of other cond...

Vitamin D has been associated with decreased risk of several cancers. In experimental studies, vitamin D has been shown to inhibit cell proliferation and induce differentiation and apoptosis in normal and malignant breast cells. Using a population-based case-control study on Long Island, New York, we examined the association of breast cancer with plasma 25-hydroxyvitamin D (25-OHD) levels, a me...

the dried plant was extracted with dichloromethane and after defatting with hexane, transferred repeatedly on silica columns using dichloromethane-hexane and ethyl acetate-hexane as mobile phases. finally the fractions were purified by high performance liquid chromatography using a pack-sil column and hexane: ethyl acetate as mobile phase. the structures of the isolated compounds included: cycl...

In recent years it has been shown that vitamin D deficiency is associated with an increased incidence as well as the progression of a broad range of diseases including osteoporosis, rickets, cardiovascular disease, autoimmune disease, multiple sclerosis and cancer. Consequently, requests for the assessment of vitamin D status have increased dramatically. Despite significant progress in the anal...

Purpose The primary aim is to compare the change in serum 25OHD concentration between three forms of supplemental vitamin D3: a lipid-emulsified form administered in a sesame oil base, a non-emulsified chewable tablet, and a non-emulsified form administered to 25-hydroxycholecalciferol (25-OHD) insufficient <33ng/ml (75 nmol/ml) patients. The secondary aim is to compare the proportion of partic...

Serum 24,25-dihydroxy vitamin D (24,25(OH)2D) and 25-hydroxy vitamin D (25-OHD) concentrations and the ratio between the two were measured in 31 Israeli children and adolescents receiving long-term treatment with phenobarbitone or phenytoin and in controls. 24,25 (OH)2D concentrations were significantly depressed in the patients, although the 25-OHD concentrations were similar to those in the h...

A key question for healthcare is how to operationalize the vision of the Learning Healthcare System, in which electronic health record data become a continuous information source for quality assurance and research. This project presents an initial, ontology-based, method for secondary use of electronic dental record (EDR) data. We defined a set of dental clinical research questions; constructed...
