Marfan Syndrome
An autosomal dominant disorder of CONNECTIVE TISSUE with abnormal features in the heart, the eye, and the skeleton. Cardiovascular manifestations include MITRAL VALVE PROLAPSE, dilation of the AORTA, and aortic dissection. Other features include lens displacement (ectopia lentis), disproportioned long limbs and enlarged DURA MATER (dural ectasia). Marfan syndrome is associated with mutations in the gene encoding fibrillin, a major element of extracellular microfibrils of connective tissue.
Acetylcholine
Nitric Oxide
A free radical gas produced endogenously by a variety of mammalian cells, synthesized from ARGININE by NITRIC OXIDE SYNTHASE. Nitric oxide is one of the ENDOTHELIUM-DEPENDENT RELAXING FACTORS released by the vascular endothelium and mediates VASODILATION. It also inhibits platelet aggregation, induces disaggregation of aggregated platelets, and inhibits platelet adhesion to the vascular endothelium. Nitric oxide activates cytosolic GUANYLATE CYCLASE and thus elevates intracellular levels of CYCLIC GMP.

Norepinephrine
Precursor of epinephrine that is secreted by the adrenal medulla and is a widespread central and autonomic neurotransmitter. Norepinephrine is the principal transmitter of most postganglionic sympathetic fibers and of the diffuse projection system in the brain arising from the locus ceruleus. It is also found in plants and is used pharmacologically as a sympathomimetic.
Apolipoproteins E
A class of protein components which can be found in several lipoproteins including HIGH-DENSITY LIPOPROTEINS; VERY-LOW-DENSITY LIPOPROTEINS; and CHYLOMICRONS. Synthesized in most organs, Apo E is important in the global transport of lipids and cholesterol throughout the body. Apo E is also a ligand for LDL receptors (RECEPTORS, LDL) that mediates the binding, internalization, and catabolism of lipoprotein particles in cells. There are several allelic isoforms (such as E2, E3, and E4). Deficiency or defects in Apo E are causes of HYPERLIPOPROTEINEMIA TYPE III.

RNA, Messenger
RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.
Aortic Arch Syndromes
Conditions resulting from abnormalities in the arteries branching from the ASCENDING AORTA, the curved portion of the aorta. These syndromes are results of occlusion or abnormal blood flow to the head-neck or arm region leading to neurological defects and weakness in an arm. These syndromes are associated with vascular malformations; ATHEROSCLEROSIS; TRAUMA; and blood clots.
Methylene Blue
A compound consisting of dark green crystals or crystalline powder, having a bronze-like luster. Solutions in water or alcohol have a deep blue color. Methylene blue is used as a bacteriologic stain and as an indicator. It inhibits GUANYLATE CYCLASE, and has been used to treat cyanide poisoning and to lower levels of METHEMOGLOBIN.
Mice, Knockout
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.

A molecular pathway revealing a genetic basis for human cardiac and craniofacial defects. (1/4396)
Microdeletions of chromosome 22q11 are the most common genetic defects associated with cardiac and craniofacial anomalies in humans. A screen for mouse genes dependent on dHAND, a transcription factor implicated in neural crest development, identified Ufd1, which maps to human 22q11 and encodes a protein involved in degradation of ubiquitinated proteins. Mouse Ufd1 was specifically expressed in most tissues affected in patients with 22q11 deletion syndrome. The human UFD1L gene was deleted in all 182 patients studied with 22q11 deletion, and a smaller deletion of approximately 20 kilobases that removed exons 1 to 3 of UFD1L was found in one individual with features typical of 22q11 deletion syndrome. These data suggest that UFD1L haploinsufficiency contributes to the congenital heart and craniofacial defects seen in 22q11 deletion. (+info)The cyclo-oxygenase-dependent regulation of rabbit vein contraction: evidence for a prostaglandin E2-mediated relaxation. (2/4396)
1. Arachidonic acid (0.01-1 microM) induced relaxation of precontracted rings of rabbit saphenous vein, which was counteracted by contraction at concentrations higher than 1 microM. Concentrations higher than 1 microM were required to induce dose-dependent contraction of vena cava and thoracic aorta from the same animals. 2. Pretreatment with a TP receptor antagonist (GR32191B or SQ29548, 3 microM) potentiated the relaxant effect in the saphenous vein, revealed a vasorelaxant component in the vena cava response and did not affect the response of the aorta. 3. Removal of the endothelium from the venous rings, caused a 10 fold rightward shift in the concentration-relaxation curves to arachidonic acid. Whether or not the endothelium was present, the arachidonic acid-induced relaxations were prevented by indomethacin (10 microM) pretreatment. 4. In the saphenous vein, PGE2 was respectively a 50 and 100 fold more potent relaxant prostaglandin than PGI2 and PGD2. Pretreatment with the EP4 receptor antagonist, AH23848B, shifted the concentration-relaxation curves of this tissue to arachidonic acid in a dose-dependent manner. 5. In the presence of 1 microM arachidonic acid, venous rings produced 8-10 fold more PGE2 than did aorta whereas 6keto-PGF1alpha and TXB2 productions remained comparable. 6. Intact rings of saphenous vein relaxed in response to A23187. Pretreatment with L-NAME (100 microM) or indomethacin (10 microM) reduced this response by 50% whereas concomitant pretreatment totally suppressed it. After endothelium removal, the remaining relaxing response to A23187 was prevented by indomethacin but not affected by L-NAME. 7. We conclude that stimulation of the cyclo-oxygenase pathway by arachidonic acid induced endothelium-dependent, PGE2/EP4 mediated relaxation of the rabbit saphenous vein. This process might participate in the A23187-induced relaxation of the saphenous vein and account for a relaxing component in the response of the vena cava to arachidonic acid. It was not observed in thoracic aorta because of the lack of a vasodilatory receptor and/or the poorer ability of this tissue than veins to produce PGE2. (+info)Enantioselective inhibition of the biotransformation and pharmacological actions of isoidide dinitrate by diphenyleneiodonium sulphate. (3/4396)
1. We have shown previously that the D- and L- enantiomers of isoidide dinitrate (D-IIDN and L-IIDN) exhibit a potency difference for relaxation and cyclic GMP accumulation in isolated rat aorta and that this is related to preferential biotransformation of the more potent enantiomer (D-IIDN). The objective of the current study was to examine the effect of the flavoprotein inhibitor, diphenyleneiodonium sulphate (DPI), on the enantioselectivity of IIDN action. 2. In isolated rat aortic strip preparations, exposure to 0.3 microM DPI resulted in a 3.6 fold increase in the EC50 value for D-IIDN-induced relaxation, but had no effect on L-IIDN-induced relaxation. 3. Incubation of aortic strips with 2 microM D- or L-IIDN for 5 min resulted in significantly more D-isoidide mononitrate formed (5.0 +/- 1.5 pmol mg protein(-1)) than L-isoidide mononitrate (2.1 +/- 0.7 pmol mg protein(-1)) and this difference was abolished by pretreatment of tissues with 0.3 microM DPI. DPI had no effect on glutathione S-transferase (GST) activity or GSH-dependent biotransformation of D- or L-IIDN in the 105,000 x g supernatant fraction of rat aorta. 4. Consistent with both the relaxation and biotransformation data, treatment of tissues with 0.3 microM DPI significantly inhibited D-IIDN-induced cyclic GMP accumulation, but had no effect on L-IIDN-induced cyclic GMP accumulation. 5. In the intact animal, 2 mg kg(-1) DPI significantly inhibited the pharmacokinetic and haemodynamic properties of D-IIDN, but had no effect L-IIDN. 6. These data suggest that the basis for the potency difference for relaxation by the two enantiomers is preferential biotransformation of D-IIDN to NO, by an enzyme that is inhibited by DPI. Given that DPI binds to and inhibits NADPH-cytochrome P450 reductase, the data are consistent with a role for the cytochromes P450-NADPH-cytochrome P450 reductase system in this enantioselective biotransformation process. (+info)Effect of acute and long-term treatment with 17-beta-estradiol on the vasomotor responses in the rat aorta. (4/4396)
1. This study sought to evaluate whether the effects of acute and long-term treatment with 17-beta-estradiol on the vasomotor responses in rat aortic rings are mediated through the same mechanism. 2. Ovariectomized rats were treated daily with either 17-beta-estradiol-3-benzoate (100 microg kg(-1)) or vehicle for 1 week. 3. The effect of long-term 17-beta-estradiol treatment on the responses to cumulative doses of phenylephrine, 5-HT, calcium, potassium and 17-beta-estradiol was determined in aortic rings. In the same rings, the effect of acute exposure to 17-beta-estradiol (5 and 10 microM) on the dose response curves for phenylephrine, 5-HT, calcium, potassium and acetylcholine were estimated. The measurements were made in rings with and without intact endothelium. The tone-related basal release of nitric oxide (NO) was measured in rings with intact endothelium. 4. Long-term 17-beta-estradiol treatment reduced the maximum developed contraction to all contracting agents studied. This effect was abolished in endothelium denuded vessels. Acute 17-beta-estradiol treatment also reduced maximal contraction. This effect, however, was independent of the endothelium. 5. Long-term 17-beta-estradiol treatment significantly increased the ability of the rings to dilate in response to acetylcholine whereas acute exposure to 17-beta-estradiol had no effect. The tone-related release of NO was significantly increased after long-term exposure to 17-beta-estradiol. 6. In conclusion, this study indicate that the acute and long-term effects of 17-beta-estradiol in the rat aorta are mediated through different mechanisms. The long-term effect is mediated through the endothelium most likely by increasing NO release. In contrast, the acute effect of 17-beta-estradiol seems to be through an effect on the vascular smooth muscle cells. (+info)Studies of the role of endothelium-dependent nitric oxide release in the sustained vasodilator effects of corticotrophin releasing factor and sauvagine. (5/4396)
1. The mechanisms of the sustained vasodilator actions of corticotrophin-releasing factor (CRF) and sauvagine (SVG) were studied using rings of endothelium de-nuded rat thoracic aorta (RTA) and the isolated perfused rat superior mesenteric arterial vasculature (SMA). 2. SVG was approximately 50 fold more potent than CRF on RTA (EC40: 0.9 +/- 0.2 and 44 +/- 9 nM respectively, P < 0.05), and approximately 10 fold more active in the perfused SMA (ED40: 0.05 +/- 0.02 and 0.6 +/- 0.1 nmol respectively, P < 0.05). Single bolus injections of CRF (100 pmol) or SVG (15 pmol) in the perfused SMA caused reductions in perfusion pressure of 23 +/- 1 and 24 +/- 2% that lasted more than 20 min. 3. Removal of the endothelium in the perfused SMA with deoxycholic acid attenuated the vasodilatation and revealed two phases to the response; a short lasting direct action, and a sustained phase which was fully inhibited. 4. Inhibition of nitric oxide synthase with L-NAME (100 microM) L-NMMA (100 microM) or 2-ethyl-2-thiopseudourea (ETPU, 100 microM) had similar effects on the vasodilator responses to CRF as removal of the endothelium, suggesting a pivotal role for nitric oxide. However the selective guanylate cyclase inhibitor 1H-[l,2,4]oxadiazolo[4,3-alpha]quinoxalin-1-one (ODQ, 10 microM) did not affect the response to CRF. 5. High potassium (60 mM) completely inhibited the vasodilator response to CRF in the perfused SMA, indicating a role for K channels in this response. 6. Compared to other vasodilator agents acting via the release of NO, the actions of CRF and SVG are strikingly long-lasting, suggesting a novel mechanism of prolonged activation of nitric oxide synthase. (+info)Protective effect of dietary tomato against endothelial dysfunction in hypercholesterolemic mice. (6/4396)
The effects of dietary ingestion of tomato were studied in mice that had been made hypercholesterolemic by feeding atherogenic diets. Mice which had been fed on the atherogenic diet without tomato for 4 months had significantly increased plasma lipid peroxide, and the vaso-relaxing activity in the aorta induced by acetylcholine (ACh) was harmed when compared with mice fed on a common commercial diet. On the other hand, mice which had been fed on the atherogenic diet containing 20% (w/w) lyophilized powder of tomato showed less increase in the plasma lipid peroxide level, and ACh-induced vaso-relaxation was maintained at the same level as that in normal mice. These results indicate that tomato has a preventive effect on atherosclerosis by protecting plasma lipids from oxidation. (+info)Effects of docosahexaenoic and eicosapentaenoic acid on lipid metabolism, eicosanoid production, platelet aggregation and atherosclerosis in hypercholesterolemic rats. (7/4396)
Exogenously hypercholesterolemic (ExHC) rats were fed on an atherogenic diet supplemented with 1% each of either ethyl ester docosahexaenoic acid [EE-DHA, 22:6(n-3)], ethyl ester eicosapentaenoic acid [EE-EPA, 20:5(n-3)] or safflower oil (SO) for 6 months. The rats fed on the diets containing EE-EPA or EE-DHA, compared with those fed on SO, had lower serum cholesterol and triacylglycerol levels, less aggregation of platelets and slower progress of intimal thickening in the ascending aorta. Relative to the SO-fed rats, both of the (n-3) fatty acid-fed rats had a significantly reduced proportion of arachidonic acid in the platelet and aortic phospholipids, and lower production of thromboxane A2 by platelets and of prostacyclin by the aorta. These results suggest that EPA and DHA are similarly involved in preventing atherosclerosis development by reducing hypercholesterolemia and modifying the platelet functions. (+info)Modulation of temperature-induced tone by vasoconstrictor agents. (8/4396)
One of the primary cardiovascular adjustments to hyperthermia is a sympathetically mediated increase in vascular resistance in the viscera. Nonneural factors such as a change in vascular tone or reactivity may also contribute to this response. Therefore, the aim of this study was to determine whether vascular smooth muscle tone is altered during heating to physiologically relevant temperatures >37 degrees C. Gradually increasing bath temperature from 37 degrees C (normothermia) to 43 degrees C (severe hyperthermia) produced graded contractions in vascular ring segments from rat mesenteric arteries and thoracic aortae. In untreated rings these contractions were relatively small, whereas hyperthermia elicited near-maximal increases in tension when rings were constricted with phenylephrine or KCl before heating. In phenylephrine-treated mesenteric arterial rings, the contractile responses to heating were markedly attenuated by the Ca2+ channel antagonists nifedipine and diltiazem. Diltiazem also blocked the contractile responses to heating in thoracic aortic rings. These results demonstrate that hyperthermia has a limited effect on tension generation in rat vascular smooth muscle in the absence of vascular tone. However, in the presence of agonist-induced tone, tension generation during heating is markedly enhanced and dependent on extracellular Ca2+. In conclusion, these data suggest that local regulation of vascular tone can contribute to the hemodynamic adjustments to hyperthermia. (+info)

- In this work, a semi-automatic software package that allows the assessment of thoracic aorta diameters from baseline and follow-up CTs (and their differences), was presented, and demonstrated high accuracy and low inter-observer variability. (eur.nl)
Aortic injury3
- However, most patients that have a thoracic aortic injury do not live for 24 hours. (wikipedia.org)
- It is difficult to rely on symptoms to diagnose a thoracic aortic injury. (wikipedia.org)
- Repair of a thoracic aortic injury is associated with significant morbidity. (openanesthesia.org)
Supravalvular aorta1
- Normal ascending aorta: aortic root, sinotubular junction, and supravalvular aorta. (bmj.com)
Left ventricle2
- The aorta originates from the left ventricle of the heart. (healthline.com)
- The initial part of the aorta, the ascending aorta, rises out of the left ventricle, from which it is separated by the aortic valve. (wikipedia.org)
Coarctation3
- Surgical treatment of the thoracic coarctation did not influence blood pressure which remained normal. (ebscohost.com)
- The effect of cardiac motion on aortic flow is important when assessing sequelae in this region including coarctation of the aorta (CoA) or regurgitant fraction. (asme.org)
- Advancements in this area are particularly important for patients diagnosed with coarctation of the aorta (CoA) [ 13 - 19 ]. (asme.org)
Myoblast cells1
- Fluorescence emission intensity from a culture of embryonic rat thoracic aorta medial layer ( A-10 line) myoblast cells that were transfected with a pEYFP-Actin plasmid subcellular localization vector. (microscopyu.com)
Injuries4
- There are different grades to injuries to the aorta depending on the extent of injury, and the treatment whether surgical or medical depends on that grade. (wikipedia.org)
- Injuries to the aorta are usually the result of trauma, such as deceleration and crush injuries. (wikipedia.org)
- Many of these injuries are fatal, however those that survive deserve immediate attention - a 15 year series of 114 thoracic aorta ruptures following blunt-trauma (Maryland Shock Trauma) showed that, despite a 78% initial survival rate (resuscitation) the overall survival rate was only 47% [Cowley RA et al. (openanesthesia.org)
- However, the vast majority of thoracic aortic injuries from full frontal impacts take place when the Delta V is between 28 MPH and 84 MPH. (ligorilaw.com)
Vessel4
- Ascending thoracic aortic aneurysms are associated with compositional remodeling and vessel stiffening but not weakening in age-matched subjects. (semanticscholar.org)
- One LifeLike Thoracic Aorta vessel including a resealable pouch to keep product moist. (fauxmedical.com)
- Sharpness of the thoracic aorta was also evaluated quantitatively at three levels by generating a line profile across the aortic vessel wall and calculating the point spread function. (biomedcentral.com)
- The purpose of this study was to investigate 3D flow patterns and vessel wall parameters in patients with dilated ascending aorta, age-matched subjects, and healthy volunteers. (biomedcentral.com)
Surgical3
- 3 ] To date, two interventions are mainly used to manage this condition: The surgical repair and thoracic endovascular aortic repair. (lww.com)
- For patients with more complex conditions, open surgical repair of the aorta may be combined with another catheter-based procedure. (templehealth.org)
