Recently, circular RNAs (circRNAs) have been revealed to be an important non-coding element of the transcriptome. The brain contains the most abundant and widespread expression of circRNA. There are also indications that the circular transcriptome un

Normal aging is associated with impairments in cognitive functions. These alterations are caused by diminutive changes in the biology of synapses, and ineffective neurotransmission, rather than loss of neurons. Hitherto, only a few studies, exploring

In this paper we present a generalized physicochemical model for carrier ampholyte isoelectric focusing techniques. Accurate analysis of electrokinetic phenomena can only be performed when the physicochemical interactions of the carrier matrix with t

In the present paper, we present our results from studies where the electrode solutions were separated from the carrier with the polytetrafluoroethylene-based membranes (Nafion®). We achieved a 40-fold decrease of the average ionic strength in the g

While studying the effect of electrochemical reactions occurring at the electrodes on achievement of steady state in isoelectric focusing (IEF) we observed an abnormal increase of the current. Because the magnitude of the current determines the progr

The process occurring as the background to IEF is electrolysis of water. During IEF the yield of water ions decreases, following a non-linear relationship similar to that of the current. Different extents of acidification and basification of the elec

A serious drawback of the carrier ampholyte isoelectric focusing is the undetermined ionic strength at which the proteins separate. We tried to study its effect in order to bridge the gap between theory and practice giving a quantitative and qualitat

To elucidate the functional role of the amyloid precursor protein (APP) during brain ontogeny, developmental changes of APP levels in growth cones and synaptosomes were studied from embryonic day 14 up to postnatal day (PD) 400 using Western analysis

The up-regulation of the angiogenic vascular endothelial growth factor (VEGF) in brains of Alzheimer patients in close relationship to beta-amyloid (Abeta) plaques, suggests a link of VEGF action and processing of the amyloid precursor protein (APP).

During synaptogenesis the plasma membrane of neurons undergoes considerable changes and large portions of it develop to synaptic membranes. This transformation is brought about by biochemical and morphological changes. The aim of the present investig
