Parkinson's disease (PD) consists of loss of pigmented dopamine-secreting neurons in the pars compacta of the midbrain substantia nigra. These neurons project to the striatum (putamen and caudate nucleus) and their loss leads to alterations in the activity of the neural circuits that regulate movement. In a simplified model, two dopamine pathways are(More)
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)
Paraneoplastic neurological syndromes are immune-mediated effects of cancer that involve the nervous system and are associated with various anti-neuronal antibodies. They can be associated with several cancers such as lung, gynecologic, thymic, testicular and others, but the diagnosis of cancer often becomes a challenge, since paraneoplastic neurological(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)
Central and peripheral nervous system toxicity are frequent complications of most chemotherapy regimens, often leading to reduction of dosages or cessation of the responsible drugs. However, sometimes the afflicted toxicity may not be reversible, especially if it is not recognized early, further compromising the quality of life of the cancer patients. The(More)
We have previously demonstrated the effectiveness of adenovirus-mediated expression of antisense urokinase-type plasminogen activator receptor (uPAR) and matrix metalloproteinase-9 (MMP-9) in inhibiting tumor invasion in vitro and ex vivo. However, the therapeutic effect of the adenovirus-mediated antisense approach was shown to be transient and required(More)
In gliomas, germline gene alterations play a significant role during malignant transformation of progenitor glial cells, at least for families with occurrence of multiple cancers or with specific hereditary cancer syndromes. Scientific evidence during the last few years has revealed several constitutive genetic abnormalities that may influence glioma(More)
Meningioma is a common intracranial tumor, originating from the meninges of the skull or spinal canal. Most meningiomas are benign tumors, however atypical or anaplastic tumors can be found in 6% of cases. Patients with asymptomatic small benign meningiomas can be followed without therapy, but in symptomatic patients complete surgical resection should be(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)
Multiple sclerosis (MS) is associated with reduced bone mass and higher frequency of osteoporosis. Although high-dose short-term intravenous glucocorticoid regimens cause a decrease in bone formation, this effect is usually reversible and osteoporosis in MS patients may be independent of the short-term corticosteroid treatment. Clinical evidence suggests an(More)
