Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease characterized by loss of motor neurons in the spinal cord, brain stem and motor cortex which dramatically reduces life expectancy. ALS occurs either in familial or, more frequently, in sporadic forms. It finally results in death due to respiratory failure that occurs typically(More)
PURPOSE Symptoms of depression are present in 40 to 60 percent of patients with epilepsy. Prior research indicated significant correlation between the incidence and frequency of focal seizures and clinical depression, especially in patients with temporal lobe epilepsy. Anticonvulsive drugs and psychosocial factors contribute to the occurrence of depression(More)
Cytidine-5-diphosphocholine (CDP-choline, citicoline) is an endogenous nucleoside involved in generation of phospholipids, membrane formation and its repair. It demonstrates beneficial effects in certain central nervous system injury models, including cerebral ischaemia, neurodegenerative disorders and spinal cord injury. Defective neuronal and/or glial(More)
There is increasing evidence that so-called "autophagic cell death" participates in cell degeneration in certain pathological conditions. Autophagy might be involved in some neurodegenerative processes, including lateral amyotrophic sclerosis (SLA). The exact mechanism leading to progressive motor neuron (MN) loss remains unclear, but glutamate-mediated(More)
PURPOSE Lamotrigine (LTG) is a novel anticonvulsant drug that exerts an antiepileptic effect by decreasing glutamate release through inhibition of voltage-sensitive sodium channels. LTG has no effect on serum levels of most female reproductive hormones, but its effect on male reproductive hormones still remains unclear. Improvement in sexual function after(More)
Erythropoietin (EPO) is a chemokine hormone that is widely distributed throughout the body including nervous system. For last years its role as cytokine involved in many physiological processes out of the bone marrow has been suggested. Moreover, it plays a very important role in CNS as potential neuroprotective agent. There is much evidence that EPO(More)
The defective glial and/or neuronal glutamate transport may, in chronic neurotoxicity, contribute to several neurodegenerative diseases including amyotrophic lateral sclerosis (ALS)--a progressive neurodegenerative disorder of lower and upper motor neurons (MNs). To determine the detailed ultrastructural characteristics of excitotoxic motor neurons(More)
Chronic excitotoxicity mediated through defective glial and/or neuronal glutamate transport may contribute to several neurodegenerative diseases including amyotrophic lateral sclerosis (ALS). This study was performed to determine the ultrastructural characteristics of astroglial changes concomitant with motor neuron (MN) degeneration in a model of slow(More)
Both the neurotoxic and neuroprotective effects of zinc have been well established, but the exact mechanism of its dual abilities still remains unclear. It has been shown that zinc deficiency leads to progressive neuronal injury. Therefore a safe zinc concentration levels seem to be necessary in neuronal protection from different noxious factors. This study(More)
Meningiomas exhibit a broad spectrum of differentiation potency corresponding to different histological subtypes. The separate secretory or lipomatous transformation of meningothelial cells is uncommonly encountered in meningiomas classified into distinct secretory or lipomatous variants. The coexistence of these two different histological subtypes is(More)
