N1-Acetylspermidine is not detectable in rat heart, but its content greatly increases after a single injection of isoprenaline (10 mg/kg), reaching a concentration of about 10 nmol/g of tissue 4 h after the treatment. Part of the accumulated N1-acetylspermidine was split to putrescine. Isoprenaline also caused an increase of N1-acetylspermidine in the spleen, where its concentration increased 3...

It has been suggested that chronic alcoholism may lead to altered neural mechanisms related to inhibitory processes. Here, we studied auditory N1 suppression phenomena (i.e. amplitude reduction with repetitive stimuli) in chronic alcoholic patients as an early-stage information-processing brain function involving inhibition by the analysis of the N1 event-related potential and time-frequency co...

• P = {1, 2, 3, . . .} • Seq = {< n1, . . . , nk > | k > 0, n1, . . . , nk ∈ P}. p, q, r and s, possibly decorated, are metavariables ranging over Seq. • If p =< m1, . . . ,mk > and q =< n1, . . . , nl > then p ∗ q = 〈m1, . . . ,mk, n1, . . . , nl〉. • p ∗ 〈 〉 = 〈 〉 ∗ p = p for every p ∈ Seq. • p 6 q iff there is s such that p ∗ s = q. Definition 1.1 (Trees). T ⊆ Seq is a tree iff: 1. q ∈ T and ...

It is still a question of debate whether the N1-P2 complex is an index of low-level auditory processes or whether it can capture higher-order information encoded in the immediate context. To address this issue, the current study examined the morphology of the N1-P2 complex as a function of context regularities instantiated at the sublexical level. We presented two types of speech targets in iso...

The neuron-specific N1 exon of the mouse c-src transcript is normally skipped in nonneuronal cells. In this study, we examined the sequence requirements for the exclusion of this exon in nonneuronal HeLa cell nuclear extracts. We found that the repression of the N1 exon is mediated by specific intron sequences that flank the N1 exon. Mutagenesis experiments identified conserved CUCUCU elements ...

We compare the complexity of “internal” and “external” equivalence checking. The former is meant for proving the correctness of a synthesis transformation by which circuit N2 is obtained from circuit N1. The latter is meant for proving that circuits N1 and N2 are functionally equivalent without making any explicit assumptions about the origin of N1 and N2. We describe logic synthesis procedures...

Existing 67-channel event-related potentials, obtained during recognition and working memory paradigms with words or faces, were used to examine early visual processing in schizophrenia patients prone to auditory hallucinations (AH, n = 26) or not (NH, n = 49) and healthy controls (HC, n = 46). Current source density (CSD) transforms revealed distinct, strongly left- (words) or right-lateralize...

We discuss a discrete mutualism model with variable delays of the forms N1 n 1 N1 n exp{r1 n K1 n α1 n N2 n − μ2 n /1 N2 n − μ2 n − N1 n − ν1 n }, N2 n 1 N2 n exp{r2 n K2 n α2 n N1 n − μ1 n / 1 N1 n − μ1 n − N2 n − ν2 n }. By means of an almost periodic functional hull theory, sufficient conditions are established for the existence and uniqueness of globally attractive almost periodic solution ...

Previous studies have reported that individual variation in N1 amplitude is related to attentional problems and alcoholism. Using data from 651 twins and siblings from 292 families we examined whether variation in N1 amplitude and latency can be explained by genetic factors. In half of the subjects the age centered around 26 (young adult cohort), in the other half the age centered around 49 (mi...

OBJECTIVE Galvanic vestibular stimulation (GVS) delivered as zero-mean current noise (noisy GVS) has been shown to improve static and dynamic postural stability probably by enhancing vestibular information. The purpose of this study was to examine the effect of an imperceptible level noisy GVS on ocular vestibular-evoked myogenic potentials (oVEMPs) in response to bone-conducted vibration (BCV)...
