Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen.
A nicotinic cholinergic antagonist often referred to as the prototypical ganglionic blocker. It is poorly absorbed from the gastrointestinal tract and does not cross the blood-brain barrier. It has been used for a variety of therapeutic purposes including hypertension but, like the other ganglionic blockers, it has been replaced by more specific drugs for most purposes, although it is widely used a research tool.

Strains of mice in which certain GENES of their GENOMES have been disrupted, or "knocked-out". To produce knockouts, using RECOMBINANT DNA technology, the normal DNA sequence of the gene being studied is altered to prevent synthesis of a normal gene product. Cloned cells in which this DNA alteration is successful are then injected into mouse EMBRYOS to produce chimeric mice. The chimeric mice are then bred to yield a strain in which all the cells of the mouse contain the disrupted gene. Knockout mice are used as EXPERIMENTAL ANIMAL MODELS for diseases (DISEASE MODELS, ANIMAL) and to clarify the functions of the genes.

Early specification of sensory neuron fate revealed by expression and function of neurogenins in the chick embryo. (1/953)

The generation of sensory and autonomic neurons from the neural crest requires the functions of two classes of basic helix-loop-helix (bHLH) transcription factors, the Neurogenins (NGNs) and MASH-1, respectively (Fode, C., Gradwohl, G., Morin, X., Dierich, A., LeMeur, M., Goridis, C. and Guillemot, F. (1998) Neuron 20, 483-494; Guillemot, F., Lo, L.-C., Johnson, J. E., Auerbach, A., Anderson, D. J. and Joyner, A. L. (1993) Cell 75, 463-476; Ma, Q., Chen, Z. F., Barrantes, I. B., de la Pompa, J. L. and Anderson, D. J. (1998 Neuron 20, 469-482). We have cloned two chick NGNs and found that they are expressed in a subset of neural crest cells early in their migration. Ectopic expression of the NGNs in vivo biases migrating neural crest cells to localize in the sensory ganglia, and induces the expression of sensory neuron-appropriate markers in non-sensory crest derivatives. Surprisingly, the NGNs can also induce the expression of multiple pan-neuronal and sensory-specific markers in the dermomyotome, a mesodermal derivative. Taken together, these data suggest that a subset of neural crest cells may already be specified for a sensory neuron fate early in migration, as a consequence of NGN expression.  (+info)

Rhythmic swimming activity in neurones of the isolated nerve cord of the leech. (2/953)

1. Repeating bursts of motor neurone impulses have been recorded from the nerves of completely isolated nerve cords of the medicinal leech. The salient features of this burst rhythm are similar to those obtained in the semi-intact preparation during swimming. Hence the basic swimming rhythm is generated by a central oscillator. 2. Quantitative comparisons between the impulse patterns obtained from the isolated nerve cord and those obtained from a semi-intact preparation show that the variation in both dorsal to ventral motor neurone phasing and burst duration with swim cycle period differ in these two preparations. 3. The increase of intersegmental delay with period, which is a prominent feature of swimming behaviour of the intact animal, is not seen in either the semi-intact or isolated cord preparations. 4. In the semi-intact preparation, stretching the body wall or depolarizing an inhibitory motor neurone changes the burst duration of excitatory motor neurones in the same segment. In the isolated nerve cord, these manipulations also change the period of the swim cycle in the entire cord. 5. These comparisons suggest that sensory input stabilizes the centrally generated swimming rhythm, determines the phasing of the bursts of impulses from dorsal and ventral motor neurones, and matches the intersegmental delay to the cycle period so as to maintain a constant body shape at all rates of swimming.  (+info)

Physiological properties and receptive fields of mechanosensory neurones in the head ganglion of the leech: comparison with homologous cells in segmental ganglia. (3/953)

A study of the head ganglion of the leech was made to compare the properties of specific sensory cells in this ganglion with those of homologous neurones in the segmental ganglia. 1. In the head ganglion, cells were identified that had electrical properties, sensory modalities and adaptation properties similar to those of touch (T), pressure (P) and nociceptive (N) cells in the segmental ganglia. The cell bodies of these neurones were situated in characteristics positions that could be correlated with those in the segmental ganglia. Several lines of evidence suggested that they were primary sensory neurones. Fewer T, P and N neurones were identified in the head ganglion than would be expected from its six constituent segmental ganglia. 2. The receptive fields of identified T, P and N cells were situated on the external surface of the head and the interior of the mouth with considerable overlap. They were generally smaller in size than those situated on the main part of the body. The receptive fields were also displaced anteriorly so that some of them were situated in segments anterior to those of the innervating cells. 3. The morphology of the sensory cells in the head ganglion was studied by intracellular injection of horseradish perioxidase. The general branching characteristics of the cells and the structural appearance of their processes resembled those of homologous cells in the segmental ganglia. However, the routes taken to the periphery by some of the cells were not constant from head ganglion to head ganglion. This variability was confirmed by electrophysiological evidence, and differed from the constancy seen in segmental sensory cells.  (+info)

Receptive fields, geometry and conduction block of sensory neurones in the central nervous system of the leech. (4/953)

1. In segmental ganglia of the leech, the cutaneous mechanosensory neurones responding to to touch innervated the skin of their own segment and of part of the anterior and posterior adjacent segments. Each touch receptive field could be divided into three non-overlapping areas: a central part innervated by the branches of the cell which ran in the nerve roots of the ganglion containing the cell body, and anterior and posterior parts innervated by its branches which ran in the nerve roots of the anterior and posterior adjacent ganglia. 2. Impulses originating from the anterior and posterior parts of the receptive fields were susceptible to conduction block within the central nervous system when the touch cells fired repetitively at frequencies that could readily be elicited with weak mechanical stimulation. In contrast, impulses originating from the central part of the receptive fields were less susceptible to block. 3. The morphology of touch cells revealed by intracellular injection of horseradish peroxidase suggested that conduction block occurred at specific bifurcation points where small cell processes joined the main process. Different physiological experiments supported this conclusion. 4. In some touch cells, bifurcation points with particularly low safety margins of conduction operated as low-pass filters, limiting the frequency of impulses capable of invading certain branches. 5. The results suggest that mechanical stimuli which would likely be encountered by the animal can lead to conduction block within its central nervous system and as a result modify its integrative activities.  (+info)

Dopaminergic synapses mediate neuronal changes in an analogue of operant conditioning. (5/953)

Feeding behavior in Aplysia can be modified by operant conditioning in which contingent reinforcement is conveyed by the esophageal nerve (E n.). A neuronal analogue of this conditioning in the isolated buccal ganglia was developed by using stimulation of E n. as an analogue of contingent reinforcement. Previous studies indicated that E n. may release dopamine. We used a dopamine antagonist (methylergonovine) to investigate whether dopamine mediated the enhancement of motor patterns in the analogue of operant conditioning. Methylergonovine blocked synaptic connections from the reinforcement pathway and the contingent-dependent enhancement of the reinforced pattern. These results suggest that dopamine mediates at least part of the neuronal modifications induced by contingent reinforcement.  (+info)

Detection of caprine herpesvirus 1 in sacral ganglia of latently infected goats by PCR. (6/953)

A study of the latency of caprine herpesvirus 1 (CpHV.1) was carried out with four latently infected goats. Three goats were treated with dexamethasone and euthanized after 4 and 6 days. PCR and virus isolation allowed us to detect CpHV.1 only in the third and fourth sacral ganglia of the two animals euthanized 6 days after the start of treatment.  (+info)

Extraventricular neurocytoma with ganglionic differentiation associated with complex partial seizures. (7/953)

We report an unusual case of extraventricular ("cerebral") neurocytoma with ganglion cells located in the right temporal lobe in a 9-year-old girl with complex partial seizures and precocious puberty. CT showed a calcified mass with central cystic zones. MR imaging showed a markedly hyperintense predominately solid tumor on both T1- and T2-weighted images, without appreciable contrast enhancement. Cerebral neurocytomas are histologically benign and radical surgery is curative; they should be included in the differential diagnosis of temporal lobe tumors in children.  (+info)

An analysis of herpes simplex virus gene expression during latency establishment and reactivation. (8/953)

In order to facilitate an analysis of the pattern of herpes simplex virus gene expression during latency establishment and reactivation, recombinant viruses containing the lacZ reporter gene under control of either the immediate early 110 (IE110) promoter or the latency-associated promoter have been constructed. Histochemical staining of ganglia taken from mice infected with these viruses allows for the rapid identification and quantification of sensory neurones in which these two promoters are active. Using the mouse ear model, this study demonstrates that, during the establishment of latency in vivo, IE110 promoter activity is only detectable in ganglia which provide innervation to the site of virus inoculation. Latency, however, is efficiently established not only in these ganglia, but also in adjacent ganglia whose neurones do not innervate the ear, and in which there was no evidence of IE110 expression during the acute phase of infection. This implies that replication-competent virus can efficiently establish latency in the absence of detectable IE110 expression. In addition, it has been possible to investigate viral gene expression in neurones following ganglionic explant culture by monitoring IE110 promoter-driven lacZ expression within reactivating neurones. This study shows that virus can be reactivated from all latently infected ganglia, but that reactivation appears to be more efficient from ganglia which provide innervation to the site of infection. The implications of these results for the mechanisms involved in latency establishment and reactivation are discussed.  (+info)

The Central Ganglion was a science fiction fanzine published by David Gordon-McDonald, Paula Johanson, E.B. Klassen, and Garth Spencer. Emerging from Victoria, British Columbia, Canada in the Spring of 1982, The Central Ganglion was conceived of by the editors as an interclub newsletter. The editors, calling themselves The Ganglion of Four, hoped to improve communications between Victorias four or five warring clubs and factions. Robert Runté wrote, It was one of Canadas better club newsletters, especially considering it didnt actually have its own club. The fanzine ran for approximately 11 issues, with the last issue appearing in November of 1983. Contributions included artwork by Dan Cawsey. David Gordon MacDonald as also a co-editor of Atavachron. Garth Spencer was also publishing The Maple Leaf Rag at the same time as The Central Ganglion. ...
The major function of the peripheral ganglia is to connect the central nervous system to the different parts of the body. The peripheral ganglia are found near target organs in the upper area of the body, more specifically, in the head. You can also find them in the abdomen, thorax, stomach, spleen, and liver kidney along the pelvis area, which act as the target organs. The genital organs and small intestines are also involved and they respond to innervations initiated by the postganglionic neurons. The peripheral ganglia are responsible in coordinating innervations coming from other organs and cells to the central nervous system.. ...
Today 56 newspapers in 45 countries take the unprecedented step of speaking with one voice through a common editorial. We do so because humanity faces a profound emergency.. Unless we combine to take decisive action, climate change will ravage our planet, and with it our prosperity and security. The dangers have been becoming apparent for a generation. Now the facts have started to speak: 11 of the past 14 years have been the warmest on record, the Arctic ice-cap is melting and last years inflamed oil and food prices provide a foretaste of future havoc. In scientific journals the question is no longer whether humans are to blame, but how little time we have got left to limit the damage. Yet so far the worlds response has been feeble and half-hearted.. Climate change has been caused over centuries, has consequences that will endure for all time and our prospects of taming it will be determined in the next 14 days. We call on the representatives of the 192 countries gathered in Copenhagen not to ...
Somehow the problem just keeps getting worse. Because we are unwilling to face a future without cars--in fact, we seem to be quite willing to sacrifice the world on the altar of the car--we seem willing to do anything to keep the cars rolling. Biofuels are one such approach; sequester carbon in plants, then convert the plants to usable fuel, and burn the fuel to keep the cars rolling while re-emitting the same carbon. The thinking is that this is, if not a zero-sum game, at least a significant reduction in the amount of carbon being added to the atmosphere. And its a great way to subsidize farmers (something all governments try to do) and an opportunity for big capital to open up a brand new market (with significant government subsidy. Without which, big capital doesnt do shit). But, of course, things arent as simple as they seem. Thus this article in the 25 March 2008 Guardian ...

TY - JOUR. T1 - Spontaneous activity in the statoacoustic ganglion of the chicken embryo. AU - Jones, Timothy A.. AU - Jones, Sherri M.. PY - 2000/3/30. Y1 - 2000/3/30. N2 - Statoacoustic ganglion cells in the mature bird include neurons that are responsive to sound (auditory) and those that are not (nonauditory). Those that are nonauditory have been shown to innervate an otolith organ, the macula lagena, whereas auditory neurons innervate the basilar papilla. In the present study, single-unit recordings of statoacoustic ganglion cells were made in embryonic (E19, mean = 19.2 days of incubation) and hatchling (P6- P14, mean = 8.6 days posthatch) chickens. Spontaneous activity from the two age groups was compared with developmental changes. Activity was evaluated for 47 auditory, 11 nonauditory, and 6 undefined eighth nerve neurons in embryos and 29 auditory, 26 nonauditory, and 1 undefined neurons in hatchlings. For auditory neurons, spontaneous activity displayed an irregular pattern [discharge ...
Atrial ganglionated plexus Stimulation Prevents Myocardial Ischemia Reperfusion Arrhythmias by Preserving Connexin43 Protein. Background: Vagal nerve stimulation has been shown to provide protective effect against ischemia/reperfusion (I/R) arrhythmias. Since atrial epicardial ganglionated plexuses contain a large amount of parasympathetic elements, we hypothesize atrial epicardial ganglionated plexus stimulation (GP-S) may be an alternative to vagal nerve stimulation for preventing arrhythmias induced by myocardial I/R.. Methods and Results: Twenty one dogs were randomly divided into GP stimulation (GP-S) group (N=11) and control group (N=10). Myocardial I/R was induced by first 2 hours of reperfusion in dogs subjected to 45 minutes of ischemia with occlusion of the left anterior descending coronary artery (LAD).

In this study the relative potencies of four established molluscan cardioexcitatory agents were examined on Buccinum heart. The potencies were, in decending order: phenylalanine-leucine-arginine-phenylalanine-NH2 (FLRFamide) , phenylalanine-methionine-arginine-phenylalanine-NH2 (FMRFamide; 80% of maximum) , 5-hydroxytryptamine (5HT; 60% of maximum) , guanosine triphosphate (GTP; 15% of maximum). FMRFamide and FLRFamide had similar dose-response curve patterns with thresholds at 10−9 mol l−1 but FLRFamide was more potent than FMRFamide. The superfused atrium was much less sensitive to all agonists than the internally perfused ventricle. FLRFamide and FMRFamide induced small depolarizations (1-2 mV) which triggered a burst of action potentials of about 5 mV which on reaching 4 mV triggered a burst of fast twitch contractions. Lithium, at high concentrations inhibited FMRFamide and 5-HT responses of internally perfused ventricles. Neomycin also inhibited peptide responses, but was without ...
The recent implementation of PET with prostate specific membrane antigen (PSMA)-specific radiotracers into the clinical practice has resulted in the significant improvement of accuracy in the detection of prostate carcinoma (PCa). PSMA-expression in ganglia has been regarded as an important pitfall in prostate carcinoma-PET diagnostics but has not found any practical use for diagnosis or therapy. We explored this phenomenon and demonstrated the applicability of peripheral ganglia in healthy rats as surrogates for small PSMA positive lesions for the preclinical evaluation of diagnostic PCa PET probes. Healthy rats were measured with PET/CT using the tracers [18F]DCFPyL, [Al18F]PSMA-11 and [68Ga]PSMA-11. Sections of ganglia were stained with an anti-PSMA antibody. [18F]DCFPyL uptake in ganglia was compared to that in LNCaP tumor xenografts in mice. Whereas [18F]DCFPyL and [68Ga]PSMA-11 were stable in vivo and accumulated in peripheral ganglia, [Al18F]PSMA-11 suffered from fast in vivo deflourination
The transport of neuropeptides between central ganglia was studied in Aplysia. Peptide transport was determined by incubating ganglia with 35S-methionine and measuring the appearance of labeled peptides in connected ganglia. Selected interganglionic connectives were left intact and passed through a diffusion barrier separating the ganglia. Labeled peptides transported between ganglia included FMRFamide, myomodulin, and pedal peptide. Each of these peptides has been shown to be physiologically active in Aplysia. In addition to these previously characterized neuropeptides, a number of other as yet uncharacterized labeled peptides were also transported. All the peptides were transported by fast axonal transport as judged by the distance transported and/or the sensitivity to colchicine. Overall, FMRFamide and several unidentified peptides were the predominant transported peptides. However, the nature and amount of the peptides transported differed for each ganglia. These results support the ...
TY - JOUR. T1 - THE DISTRIBUTION OF SEVERAL AMINO ACIDS IN SPECIFIC GANGLIA AND NERVE BUNDLES OF THE LOBSTER. AU - Aprison, M. H.. AU - Mcbride, W. J.. AU - Freeman, A. R.. PY - 1973/7. Y1 - 1973/7. N2 - Using the technique of measuring DNP amino acid methyl esters by gas liquid chromatography, the distribution of alanine, proline, glycine, GABA, glutamate and aspartate was determined in individual ganglia and the associated nerve bundles between these ganglia after isolation from the nervous system of the lobster, Homarus americanus. The brain or supraesophageal ganglion (27.2 mg) and the next 5 thoracic ganglia (varying from 24 to 10 mg in a rostral caudal direction) as well as the nerve bundles connecting these ganglia were used. GABA and aspartate values varied the most among the individual ganglia; highest values were found in the second and third thoracic ganglia. The levels of alanine, proline, glycine and glutamate varied very little from ganglion to ganglion; however, the values for ...
Aplysia californica (Alacrity, Redondo Beach, CA), weighing 80-120 g, were anesthetized by injection of isotonic MgCl2, and their abdominal and pleural-pedal ganglia were removed. Prior to desheathing, ganglia were treated with 0.5% glutaraldehyde for 50 s to prevent contraction of muscle cells in the remaining sheath. Ganglia were secured with minuten pins on wax in a recording chamber and desheathed in a 1:1 mixture of MgCl2 and artificial sea water. In experiments on facilitation of depressed synapses, synaptic connections between LE siphon SNs and LFS MNs in the abdominal ganglion were recorded after the left ventral surface of the ganglion was desheathed. In experiments on spike broadening in SNs, pleural ganglia were desheathed to expose the SNs in the ventrocaudal (VC) cluster.. Experiments were performed at room temperature. Ganglia were superfused with high-Mg2+/high-Ca2+ culture medium (6 × normal Ca2+, 1.6 × normal Mg2+) (Goldsmith and Abrams 1991) to reduce polysynaptic input and ...
The Buccal neurons are divided into motoneurons, which innervate muscles and interneurons, which are mostly confined to the buccal ganglion. The interneurons are active in turn, with each type of nterneuron only active in one phase of the rhythm. Motoneurons may be active in more than one phase. the picture below shows a simplified diagram, showing which neurons are active in any one phase ...

This is the first article in a two-part series that looks at a hands-on approach to monitoring a data center using the open source tools Ganglia and Nagios. In Part 1, see how to install and configure Ganglia, the scalable, distributed monitoring system for high-performance clusters based on a hierarchical design. Also learn how to add more monitoring capability by writing Ganglia plug-ins and by enabling external-source spoofing.
If the ganglion is asymptomatic it may not require any treatment whatsoever.. Conservative management of a ganglion consists of aspiration of the jellylike fluid and an injection of a steroid solution into the ganglion sac. This may be effective in preventing long-term recurrence in approximately 30% of patients.. If a ganglion recurs following aspiration and is symptomatic it can be removed by a small operation which is normally carried out either by numbing the arm or under a general anaesthetic. This is usually successful in preventing long-term recurrence in 70-80% of patients.. ...
The default file name is nagios_ganglia.cache in your Ganglia installs conf_dir (check out your conf.php in ganglia-webs root directory). In my case, the file was a couple weeks old, which is considerably more than the default 45 second age it was configured for! When I looked at the working system in the other DC, I saw the file being updated multiple times per minute - more often than the 45 seconds configured in conf.php - so I began to suspect that the Nagios checks themselves were triggering the cache refresh. A quick check of /var/log/httpd/ganglia_error_log made it blindingly obvious ...
