Multiple sclerosis (MS) may be associated with reduced bone mass and higher frequency of osteoporosis. Femoral and spinal bone mineral density (BMD) in 70 ambulatory MS patients (46 females and 24 males) was compared with 100 sex-, age-, and BMI-matched control individuals. BMD was reduced in male patients (lumbar spine 0.976 ± 0.114 g/cm(2) compared with(More)
The aim of this study was to compare between ambulatory patients with multiple sclerosis (MS) and control subjects, bone mineral density (BMD), and body composition, that is, percent of bone minerals (M%), fat (F%), and remaining substances (L%). Total body composition and BMD were measured by dual-energy X-ray absorptiometry in 68 patients with definite MS(More)
BACKGROUND Polymorphisms of the vitamin D receptor (VDR) gene have been linked to both multiple sclerosis (MS) and osteoporosis. We examined the frequency of the Taq-I and Bsm-I polymorphisms of the vitamin D receptor (VDR) gene in 69 patients with MS and 81 age and sex-matched healthy individuals. Genotyping of Taq-I (rs731236) and Bsm-I (rs1544410) was(More)
BACKGROUND Multiple sclerosis (MS) is a demyelinating inflammatory disease of the central nervous system originated by a complex interplay of environmental and genetic factors. The association of MS with the human leukocyte antigen (HLA) class II alleles was investigated in MS patients in northwest Greece, in the geographical region of Epirus. OBJECTIVE(More)
While traditional computer graphics research to this day still focuses on the production and assessment of photorealism, a relatively new field, the one of nonphotorealistic rendering (NPR), has produced results that focus on viewer engagement by the use of stylization, abstraction and expressiveness. In this paper we briefly describe some of the techniques(More)
