BACKGROUND The exact etiology of recurrent tonsillopharyngitis in children is not clear. Recurrent tonsillitis in children has multifactorial etiology like most of the diseases in childhood. In this study, our aim was to determine the potential role of vitamin D in recurrent tonsillitis by measuring serum 25-OH vitamin D levels and determining the vitamin D receptor polymorphism among children ...

late-onset alzheimer's disease (ad), a genetically heterogeneous neurodegenerative disorder, is the most common form of dementia in people over 65 years old. the role of vitamin d in neuropsychiatric and neurodegenerative disorders such as ad has been supported by epidemiologic investigations and animal models, as well. we examined the association of the vitamin d receptor (vdr) gene polymorphi...

The aim of this study was to determine the frequency of vitamin D receptor and estrogen receptor genotypes and their relationship with the lumbar spine or femoral neck bone mineral density in healthy pre and perimenopausal women from Córdoba (Argentina) and adjacent areas. Genotypes were assessed by restriction fragment length polymorphism-polymerase chain reaction technique. Bsm I and Fok I fo...
