Intrarenal artery injection of L-arginine inhibits spontaneous activity of renal afferent nerve fibers. (1/1054)

The purpose of this study was to determine the effect of intrarenal artery injection of L-arginine on multi- and single-unit spontaneous discharges of renal afferent nerve fibers in anesthetized rabbits. The results obtained are as follows: (1) intrarenal artery injection of L-arginine (0.05, 0.24, and 0.48 mmol/kg) decreased the renal afferent nerve activity (ARNA) in a dose-dependent manner with arterial pressure unchanged; (2) pretreatment with a nitric oxide synthase inhibitor L-NAME (N6-nitro-L-arginine methylester, 0.11 mmol/kg), completely abolished the effect of L-arginine; and (3) intrarenal artery injection of a nitric oxide donor SIN-1 (3-morpholinosydnonimine, 3.75 micromol/kg) also resulted in an inhibition of ARNA. The results suggest that intrarenal artery injection of NO precursor (L-arginine) and donor (SIN-1) can inhibit ARNA in anesthetized rabbits.  (+info)

A comparison of univariate, bivariate, and trivariate whole-genome linkage screens of genetically correlated electrophysiological endophenotypes. (2/1054)

We used a maximum-likelihood based multipoint linkage approach implemented in SOLAR to examine simultaneously linkage for three electrophysiological endophenotypes from the Collaborative Study of the Genetics of Alcoholism: TTTH1, TTTH2, and TTTH3. These endophenotypes have been identified as markers of alcohol dependence susceptibility. Data were from 905 individuals in 143 families. Measured covariates considered included sex, age at electrophysiology data collection, habitual smoking status, and the maximum number of drinks consumed in a 24-hour period. Comparisons were made among genome-wide univariate, bivariate, and trivariate linkage analyses using genotypes based on microsatellite markers supplied by the Center for Inherited Disease Research, and genotypes based on single-nucleotide polymorphism markers provided by Illumina. All LODs were corrected to a standard equivalent to 1 degree of freedom. Using the trivariate approach and the microsatellite-based genotypes, we estimated a maximum multipoint linkage signal of LOD = 2.66 on chromosome 7q at 157 cM. Analyses using the Illumina SNP genotypes produced similar results, yielding a maximum multipoint LOD of 2.95 on 7q at 174 cM. These regions of interest correspond to those identified in the univariate and bivariate linkage screens. Our results suggest that trivariate multipoint linkage analyses have utility in the further characterization of chromosomal regions potentially containing genes influencing the phenotypes being examined. Based on a comparison of the number of LOD scores achieving statistical significance, our results suggest that the microsatellite- and Illumina SNP-based genotypes have similar utility for detecting genomic regions of interest.  (+info)

Multivariate linkage analysis using the electrophysiological phenotypes in the COGA alcoholism data. (3/1054)

Multivariate linkage analysis using several correlated traits may provide greater statistical power to detect susceptibility genes in loci whose effects are too small to be detected in univariate analysis. In this analysis, we apply a new approach and perform a linkage analysis of several electrophysiological phenotypes of the Collaborative Study on the Genetics of Alcoholism data of the Genetic Analysis Workshop 14. Our approach is based on a variance-component model to map candidate genes using repeated or longitudinal measurements. It can take into account covariate effects and time-dependent genetic effects in general pedigree data. We compare our results with the ones obtained by SOLAR using single measurement data. Our multivariate linkage analysis found linkage evidence on two regions on chromosome 4: around marker GABRB1 at 51.4 cM and marker FABP2 at 116.8 cM (unadjusted p-value = 0.00006).  (+info)

A study of genetic association with electrophysiological measures related to alcoholism: GAW14 data. (4/1054)

Recently, alcohol-related traits have been shown to have a genetic component. Here, we study the association of specific genetic measures in one of the three sets of electrophysiological measures in families with alcoholism distributed as part of the Genetic Analysis Workshop 14 data, the NTTH (non-target case of Visual Oddball experiment for 4 electrode placements) phenotypes: ntth1, ntth2, ntth3, and ntth4. We focused on the analysis of the 786 Affymetrix markers on chromosome 4. Our desire was to find at least a partial answer to the question of whether ntth1, ntth2, ntth3, and ntth4 are separately or jointly genetically controlled, so we studied the principal components that explain most of the covariation of the four quantitative traits. The first principal component, which explains 70% of the covariation, showed association but not genetic linkage to two markers: tsc0272102 and tsc0560854. On the other hand, ntth1 appeared to be the trait driving the variation in the second principal component, which showed association and genetic linkage at markers in four regions: tsc0045058, tsc1213381, tsc0055068, and tsc0051777 at map distances 53.26, 85.42, 89.31, and 172.86, respectively. These results show that the partial answer to our starting question for this brief analysis is that the NTTH phenotypes are not jointly genetically controlled. The component ntth1 displays marked genetic linkage.  (+info)

Linkage analysis of alcoholism-related electrophysiological phenotypes: genome scans with microsatellites compared to single-nucleotide polymorphisms. (5/1054)

P300 amplitude is an electrophysiological quantitative trait that is correlated with both alcoholism and smoking status. Using the Collaborative Study on the Genetics of Alcoholism data, we performed model-free linkage analysis to investigate the relationship between alcoholism, P300 amplitude, and habitual smoking. We also analyzed the effect of parent-of-origin on alcoholism, and utilized both microsatellites (MS) markers and single-nucleotide polymorphisms (SNPs). We found significant evidence of linkage for alcoholism to chromosome 10; inclusion of P300 amplitude as a covariate provided additional evidence of linkage to chromosome 12. This same region on chromosome 12 showed some evidence for a parent-of-origin effect. We found evidence of linkage for the P300 phenotype to chromosome 7 in non-smokers, and to chromosome 17 in alcoholics. The effects of alcoholism and habitual smoking on P300 amplitude appear to have separate genetic determinants. Overall, there were few differences between MS and SNP genome scans. The use of covariates and parent-of-origin effects allowed detection of linkage not seen otherwise.  (+info)

Comparison of the power between microsatellite and single-nucleotide polymorphism markers for linkage and linkage disequilibrium mapping of an electrophysiological phenotype. (6/1054)

We performed linkage and linkage disequilibrium (LD) mapping analyses to compare the power between microsatellite and single nucleotide polymorphism (SNP) markers. Chromosome-wide analyses were performed for a quantitative electrophysiological phenotype, ttth1, on chromosome 7. Multipoint analysis of microsatellite markers using the variance component (VC) method showed the highest LOD score of 4.20 at 162 cM, near D7S509 (163.7 cM). Two-point analysis of SNPs using the VC method yielded the highest LOD score of 3.98 in the Illumina SNP data and 3.45 in the Affymetrix SNP data around 152-153 cM. In family-based single SNP and SNP haplotype LD analysis, we identified seven SNPs associated with ttth1. We searched for any potential candidate genes in the location of the seven SNPs. The SNPs rs1476640 and rs768055 are located in the FLJ40852 gene (a hypothetical protein), and SNP rs1859646 is located in the TAS2R5 gene (a taste receptor). The other four SNPs are not located in any known or annotated genes. We found the high density SNP scan to be superior to microsatellites because it is effective in downstream fine mapping due to a better defined linkage region. Our study proves the utility of high density SNP in genome-wide mapping studies.  (+info)

The electrophysiological properties of HVC-RA synaptic transmission in the adult zebra finch in vivo. (7/1054)

The synaptic connection from high vocal center (HVC) to robust nucleus of the arcopallium (RA) is a pivotal part of vocal motor pathway in songbirds. Electrophysiological properties of HVC-RA synaptic transmission in adult male zebra finch (Taeniopygia guttata) in vivo was investigated by using field potential recording method. Following electrical stimulation of HVC, the evoked field potentials recorded in RA were feeble. The results showed that the remarkable paired-pulse facilitation was induced by paired-pulse stimulation at HVC-RA synapses. The results also showed that the evoked field potentials were significantly decreased after a conditioning tetanic stimulation and finally recovered gradually within 15 min, which indicates tetanic stimulation-induced transient depression is present at HVC-RA synaptic transmission. These results suggest that properties of synaptic transmission in this pathway might play a role in controlling song production.  (+info)

Error processing in Huntington's disease. (8/1054)

BACKGROUND: Huntington's disease (HD) is a genetic disorder expressed by a degeneration of the basal ganglia inter alia accompanied with dopaminergic alterations. These dopaminergic alterations are related to genetic factors i.e., CAG-repeat expansion. The error (related) negativity (Ne/ERN), a cognitive event-related potential related to performance monitoring, is generated in the anterior cingulate cortex (ACC) and supposed to depend on the dopaminergic system. The Ne is reduced in Parkinson's Disease (PD). Due to a dopaminergic deficit in HD, a reduction of the Ne is also likely. Furthermore it is assumed that movement dysfunction emerges as a consequence of dysfunctional error-feedback processing. Since dopaminergic alterations are related to the CAG-repeat, a Ne reduction may furthermore also be related to the genetic disease load. METHODOLOGY/PRINCIPLE FINDINGS: We assessed the error negativity (Ne) in a speeded reaction task under consideration of the underlying genetic abnormalities. HD patients showed a specific reduction in the Ne, which suggests impaired error processing in these patients. Furthermore, the Ne was closely related to CAG-repeat expansion. CONCLUSIONS/SIGNIFICANCE: The reduction of the Ne is likely to be an effect of the dopaminergic pathology. The result resembles findings in Parkinson's Disease. As such the Ne might be a measure for the integrity of striatal dopaminergic output function. The relation to the CAG-repeat expansion indicates that the Ne could serve as a gene-associated "cognitive" biomarker in HD.  (+info)

Electrical mapping of the heart is a procedure that is used to diagnose the origins of arrhythmias. This procedure uses an electrically sensitive catheter to map the electrical activity in the chambers of the heart.. An arrhythmia is a heartbeat thats too fast, too slow or irregular (uneven). Arrhythmias are caused by problems with your hearts electrical system. The electrical signals may fire too fast or too slowly, or in an uneven (irregular) way. Abnormal electrical signals can originate in different areas of the heart (such as the atria or ventricles) causing arrhythmias.. To begin an electrical mapping procedure, a thin tube called a catheter sheath is inserted into a small incision in the arm or upper thigh. This process is usually visualized using x-rays and a special dye that helps reveal the arteries (called angiography). This catheter is carefully guided through the blood vessels until it is inside the heart. A smaller electrically sensitive catheter is then inserted inside the ...

This is a strange query. My first impulse is to say that if you want to know what relevance LTP has for medicine and health you have no business studying LTP. My impression over many years that people (and government agencies) throwing time and money at practical questions almost never discover anything relevant either to basic science OR to the practical question. LTP is an electrophysiological phenomenon which is explored intensively at molecular levels because some think it is a model for very basic processes underlying memory formation. Do you think memory formation is relevant to health isssues? A synapse is a site/structure where one neuron communicates to another via a chemical messenger. Without synapses, our brains wouldnt work. Maybe this would be a health issue. There is no end to the list of physiological phenomena which have implications for medicine and health. Why pick on LTP?

Clinical electrophysiology is the application of electrophysiology principles to medicine. The two main branches of this discipline are electrotherapy and electrophysiologic testing (EEG, electromyography, etc.) Clinical electrophysiology can be utilized in the study and treatment of various physiological conditions, and most notably in clinical cardiac electrophysiology. Cardiac Electrophysiology (also referred to as clinical cardiac electrophysiology, arrhythmia services, or electrophysiology), is a branch of the medical specialty of clinical cardiology and is concerned with the study and treatment of rhythm disorders of the heart. Through the use of electrophysiological techniques, dissections of the visual system can be made. The use of both electrophysiological information in conjunction with other clinical tests, imaging, and field instrumentation, a deep and comprehensive assessment of the ocular and visual pathways can be made. Alone, electrophysiology can also monitor ocular disease, ...
