The study of sporadic Alzheimer’s disease etiology, now more than ever, needs an infusion of new concepts. Despite ongoing interest in Alzheimer’s disease, the basis of this entity is not yet clear. At present, the best-established and accepted “culprit” in Alzheimer’s disease pathology by most scientists is the amyloid, as the main molecular factor(More)
Amyloid precursor protein cleavage through β- and γ-secretases produces β-amyloid peptide, which is believed to be responsible for death of neurons and dementia in Alzheimer’s disease. Levels of β- and γ-secretase are increased in sensitive areas of the Alzheimer’s disease brain, but the mechanism of this process is unknown. In this review, we prove that(More)
Autophagy is a major intracellular degeneration pathway involved in the elimination and recycling of damaged organelles and long-lived proteins by lysosomes. Many of the pathological factors, which trigger neurodegenerative diseases, can perturb the autophagy activity, which is associated with misfolded protein aggregates accumulation in these disorders.(More)
The interaction between brain ischemia and Alzheimer's disease (AD) has been intensively investigated recently. Nevertheless, we have not yet understood the nature and mechanisms of the ischemic episodes triggering the onset of AD and how they influence its slow progression. The assumed connection between brain ischemia and the accumulation of amyloid-β(More)
UNLABELLED Anaemia of prematurity (AOP) is caused by a deficiency of erythropoietin, which stimulates differentiation, and growth of erythroid progenitors. The previous standard of therapy of AOP was erythrocyte transfusions. Following successful clinical trials using recombinant human eryrthropoietin (rHuEpo) to treat adults, the rHuEpo has been used to(More)
BACKGROUND Brain ischemia may be causally related with Alzheimer's disease. Probably, presenilin gene dysregulation may be associated with Alzheimer's disease neuropathology. Consequently, we have examined quantitative changes in both presenilin 1 and 2 genes in the medial temporal lobe cortex following 10-min global brain ischemia in rats. METHODS Global(More)
Brain ischemia may be causally related with Alzheimer's disease. Presumably, β-secretase and amyloid-β protein precursor gene expression changes may be associated with Alzheimer's disease neuropathology. Consequently, we have examined quantitative changes in both β-secretase and amyloid-β protein precursor genes in the medial temporal lobe cortex with the(More)
OBJECTIVES The serum concentration of dehydroepiandrosterone sulfate (DHEAS) in relation to serum levels of follicle stimulating hormone, estradiol, insulin-like growth factor I (IGF-I) and height and weight velocity in girls during puberty were studied. MATERIAL AND METHODS One hundred and forty nine healthy girls aged from 9.8 to 14.7 years were(More)
The aim of the study was to establish the trend of physical growth in low-birth-weight (LBW) children, to predict the best method for early diagnosis of growth failure and to make use of biological growth standards for estimation of their postnatal growth. Physical growth of 283 LBW children was longitudinally analysed. The investigated children were(More)
