Vitamin B1 (aneurin, thiamine) is a water-soluble vitamin necessary for the normal function of the nervous system, visual system and heart and is part of important enzymes in the body. Thiamine enables the normal use of glucose, other carbohydrates and proteins, and enables the supply of energy to the organism. The main sources of thiamine are exog...

We explored the relationship between acute ischaemic stroke (IS) early functional outcome and serum levels of homocysteine, vitamin B12, and D in a noninterventional prospective clinical study. We enrolled 50 patients with first-ever IS and performed laboratory tests and functional assessment at three time points: on admission and three and six mon...

Appearance of an overcompensated positive electric field in most vertical field measurements performed very close to the channel core (0.1 m from it) is explained using the extended generalized traveling current source (extended GTCS) return stroke model with current reflections from the ground. As suggested by experiments in triggered lightning co...
Conference Paper
A new form of the space charge distribution inside the channel corona sheath that represents a generalization of previously adopted or calculated space charge densities is numerically analyzed. On one hand, the use of appropriate parameter values produces the previously established corona charge densities as special cases of this generalized distri...
Conference Paper
The extended generalized traveling current source (extended GTCS) return stroke model with current reflections from the ground is used to explain the appearance of an overcompensated positive electric field in most vertical field measurements performed very close to the channel core. As suggested by experiments in triggered lightning conditions or...

Vitamins are necessary factors in human development and normal brain function. Vitamin C is a hydrosoluble compound that humans cannot produce; therefore, we are completely dependent on food intake for vitamin C. Ascorbic acid is an important antioxidative agent and is present in high concentrations in neurons and is also crucial for collagen synth...
Conference Paper
Full-text available
A model of corona sheath that surrounds the thin core of the lightning channel has been investigated by using a new space charge function. The lightning channel is modeled by a charged corona sheath that stretches around a highly conductive central core through which the main current flows. The channel core with the negatively charged outer channel...
Conference Paper
The generalized traveling current source return stroke model (GTCS), Cvetic and Stanic [1995] is extended to take into account current reflections occurring at ground and at the upper end of the lightning channel, as well as current attenuation along the channel. The ground reflection factor and the top reflection factor of the current pulses are t...

Creutzfeldt-Jakob disease (CJD) is a fatal neurodegenerative disease caused by conformational alteration of the ubiquitous prion protein. Sporadic CJD appears to progress faster if the basal ganglia are shown to be affected on magnetic resonance imaging. Transcranial B-mode sonography (TCS) enables visualization of differences in tissue echogenicit...

Vitamin A is essential for the early development and normal functioning of the brain throughout life. A deficiency of vitamin A is one of the leading causes of morbidity and mortality in developing countries, and subclinical deficiency is probably present worldwide. The main active molecule in vitamin A is retinoic acid, which is involved in vision...

Greek physicians of the Classical Era, considered that right brain hemisphere is specialized in perception, and left for understanding and comprehension. The raise of modern neuroscience intensified studies in differences between hemispheres. The present findings highlight the fact that there is asymmetry of the hemispheres at almost all levels, as...
Conference Paper

Generalized lightning traveling current source return stroke model (GTCS) has been used to calculate the dynamics of lightning channel corona sheath surrounding thin channel core during the return stroke stage. Using measured electric field waveforms of Miki et al., 2002 in the immediate vicinity of the lightning channel, the channel discharge func...

Vascular dementia (VaD) is the second most frequent dementia after Alzheimer's disease, and is diagnosed during lifetime in 20% of demented patients. Five-year survival rate in VaD is 39%, while it is estimated to be 75% in healthy persons of the same age. It is therefore important to make correct diagnosis of VaD early in the course of the disease...

Alzheimer's disease (AD), the most prevalent dementia, is characterized not only by cognitive but also behavioral changes that pose the heaviest burden to caregivers. Differences in the clinical picture depending on the time of disease onset have been observed. We correlated cognitive and behavioral deficits in patients with presenile- and senile-o...
Article
Although typically linked to aging, small vessel disease (SVD) is also observed in younger adult patients, with common vascular risk factors (RF). We aimed to investigate features of SVD occurrence at an early adult age. Vascular RF, functional and cognitive status and severity of lesions on MRI expressed as total score on Age-Related White Matter...

Hallucinations are a psychopathological phenomenon with neuropsychological, neuroanatomical and pathophys-iological correlates in specific brain areas. They can affect any of the senses, but auditory and visual hallucinations pre-dominate. Verbal hallucinations reveal no gross organic lesions while visual hallucinations are connected to defined bra...

Patients with schizophrenia display alterations in social cognition, as well as in the realm of neurocognition. It is still unclear to what extent these two cognitive domains represent two separate dimensions or different expressions of a unified deficit. Tasks used to assess social cognition subcomponents cover basic social cognition, such as ment...

Objective Traumatic brain injury (TBI) is recently recognized as a risk factor for hypopituitarism, presented most frequently with growth hormone deficiency (GHD). GHD is associated not only with changes in body composition, but also with impaired quality of life, cognitive dysfunctions and some psychiatric sequelae, usually classified as “depressi...

Antiphospholipid syndrome (APS) is an autoimmune disease with recurrent thromboses and pregnancy complications (90% are female patients) that can be primary and secondary (with concomitant autoimmune disease). Antiphospholipid antibodies are prothrombotic but also act directly with brain tissue. One clinical and one laboratory criterion is necessar...

Subcortical white matter (WM) plays an important role in speech production and language processing. Most frequently, cerebral WM lesions are secondary to small vessel disease in patients with vascular risk factors. We report the case of a 53-year-old man with history of hypertension and ischemic subcortical lesions, who presented with speech diffic...

To determine if the patients with bipolar affective disorder, after the depressive phase, would exhibit cognitive impairment in remission. Twenty-three euthymic patients with bipolar disorder were matched, on a case-by-case basis, to twenty-one healthy subjects in the control group, for the presence of the symptoms of depression. The patients and t...

Cerebral small vessel disease is rarely described in association with pseudoxanthoma elasticum (PXE), a hereditary connective tissue disorder with skin, eye and vascular manifestations. This autosomally inherited elastic tissue disease has been attributed to mutations in the ABCC6 gene located on chromosome 16p13.1. Different stroke mechanisms are...
