To examine the angiographic and hemodynamic determinants of dipyridamole-induced ST segment depression in patients with coronary artery disease, 41 patients with angiographically documented coronary disease who underwent dipyridamole-thallium-201 myocardial scintigraphy were studied. Dipyridamole-induced ST depression occurred in 14 (34%) of the 41 patients. Stepwise multivariate logistic regression was performed to compare the predictive value of angiographic findings (good coronary collateral vessels, jeopardized collateral vessels, multivessel disease), hemodynamic changes (changes in heart rate, systolic pressure, diastolic pressure and rate-pressure product), thallium-201 results (perfusion defect, thallium-201 redistribution) and demographic data (age, gender, medications). Only the presence of good coronary collateral vessels (p less than 0.02) and increases in rate-pressure product after dipyridamole infusion (p less than 0.02) were significant multivariate predictors of dipyridamole-induced ST depression. Good collateral vessels were more common in the group with ST depression (11 [79%] of 14) than they were in the group without ST depression (6 [22%] of 27; p less than 0.001). Rate-pressure product increased 2,835 +/- 1,648 beats/ Hg in the group with ST depression compared with 1,179 +/- 1,417 beats/ Hg in patients without ST depression (p less than 0.005). In conclusion, dipyridamole-induced ST segment depression in patients with coronary artery disease appears to be related to 1) the presence of good coronary collateral vessels, which may act by facilitating "coronary steal", and 2) increases in rate-pressure product, reflecting increased myocardial oxygen demand. These observations may explain the lack of prognostic value of dipyridamole-induced ST segment depression described in previous reports.

The natural process of endothelialization, pseudointimal formation, and connective tissue incorporation of the expanded PTFE grafts in the goat was documented through histologic examination of specimens harvested at 2, 4, 6, and 8 weeks. The goats demonstrated a progressive increase in pseudointimal pannus ingrowth from the anastomoses at a rate of 11.3 mm over a 12 week period. Histologic changes according to time of vascular graft incorporation in the goat model were found to be comparable to those of the dog, pig, and calf models reported in the literature. Platelet-inhibiting drugs, aspirin, dipyridamole, nifedipine, and ibuprofen were administered to goats after replacement of their infrarenal aorta with 5 cm of 8 mm diameter expanded PTFE grafts. The effects of the drugs on graft endothelialization and anastomotic pseudointimal formation was compared with those in the untreated control group after 12 weeks. Aspirin and dipyridamole had no detrimental effect on the healing process compared with the untreated control group. Studies with nifedipine and ibuprofen did not demonstrate a decrease in pseudointimal hyperplasia. Antiplatelet treatment resulted in no significant change in the rate of endothelialization of expanded PTFE grafts.

The patients with perfusion abnormalities on ungated rest, ungated stress, or end-systolic stress images had significantly longer minimum QRS duration at rest. These QRS values correlated with SRS and SSS (r: 0.528, P: 0.01 and r: 0.47, P: 0.024, respectively). Analysis of perfusion and functional data demonstrated an inverse correlation between left ventricular ejection fraction (LVEF) and ESS (r: -0.671, P < 0.0001). The patients with end-systolic perfusion abnormalities had significantly lower LVEF rates when compared with the patients with normal perfusion on end-systolic images.

We report the case of a 25-year-old man with abdominal pain, purpura on the legs and proteinuria occurring 2 weeks after acute tonsillitis, and admitted to our hospital with suspected Henoch-Schönlein purpura nephritis (HSPN). He had increased anti-streptolysin O (ASO) titer and hypocomplementemia. A renal biopsy specimen showed endocapillary proliferative changes, which are typical of acute poststreptococcal glomerulonephritis (APSGN). However, immunofluorescence study revealed predominant IgA and C3 deposits in mesangial lesions, indicating a diagnosis of HSPN. Because of massive proteinuria initially, the treatment with a combination of prednisolone, cyclophosphamide, dipyridamole and warfarin was started along with 3 plasma exchanges. Angiotensin-converting enzyme inhibitor was also given. Response to the treatment was favorable. A follow-up biopsy was performed 8 months after the first biopsy. The renal biopsy specimen showed a figure of typical HSPN. To further investigate the cause of glomerular changes in our patient, an immunofluorescent study of nephritogenic nephritis-associated plasmin receptor (NAPlr) of group A, beta-hemolytic streptococci was performed. NAPlr was significantly positive in the glomeruli in the first biopsy specimen, but not in the second. His clinical course and pathological findings suggest that NAPlr may be related to the pathogenesis in a part of patients with HSPN, especially in patients with high ASO titer and hypocomplementemia.

Patient-reported pain and patient global assessment were the most responsive outcomes, whereas joint counts had similar responsiveness to patient-reported stiffness and physical function. Composite scores were as responsive as VAS pain, and these results encourage further elaboration and validation of composite scores in HOA in larger studies.

Studies of the uptake of [3H]adenosine ([3H]ADO) were performed using brush border membrane vesicles (BBMV) from normal (N) and hypothyroid (Tx) rat kidneys, to test if decreased Na+ reabsorption in hypothyroidism might be associated with abnormalities in ADO transport. [3H]ADO uptake (1-10 micromol) for both conditions was measured in the presence of Na+ (10-150 mmol/l); the effects of dipyridamole (10 micromol/l) and 1, 3-dipropyl-8-(2-amino-4-chlorophenyl)xanthine (PACPX, 10 micromol/l) were also studied. Na+-stimulated ADO uptake was decreased in Tx BBMV. Michaelis-Menten constants showed a decreased ADO carrier affinity (Km 2.46 +/- 0.14 in N, vs Km 4.46 +/- 0.88 micromol/l in Tx, P<0.05), with no change in the number of carriers (Vmax 295 +/- 25 in N, vs 229.2 +/- 56 protein in Tx). Na+ affinity remained unchanged (K Na+ 11.5 +/- 3.5 in N, vs K Na+ 12.72 +/- 0.7 mmol/l in Tx). Inhibition of Na+-dependent ADO transport was 50% in N as opposed to 58% in Tx with dipyridamole, and 72% in N versus 47% in Tx with PACPX. These results suggest that decreased Na+-dependent ADO cotransport contributes to the diminished tubular reabsorption that occurs in hypothyroidism.

Fifty-one patients were approached to participate of whom 48 consented to be interviewed at 6 weeks and 47 at 6 months. At 6 weeks, 36 of 38 (95%) were compliant with aspirin, 12 of 13 (92%) dipyridamole, 8 of 9 (88%) warfarin, 36 of 41 (88%) statins, 33 of 38 (87%) antihypertensive medications, and 7 of 7 (100%) diabetes medications. At 6 months, 97% were compliant with aspirin, 100% dipyridamole, 100% warfarin, 94% statins, 91% antihypertensive medications, and 100% diabetes medications. Natural or herbal remedy use was reported by 10 of 48 (21%) at 6 weeks and 11 of 47 (23%) at 6 months. Blister packs were used by 8 of 48 (17%) at 6 weeks and 5 of 47 (11%) at 6 months.

One of the coronary disease diagnostic methods of big sensitivity and specificity is perfusive effort scintrigraphy of myocardium by means of thallium-201. For few years the dipyridamole test has been applied instead of the effort test. Perfusive scintigraphy of myocardium after provocative treatment by means of dipyridamole and then selective coronary arteriography of coronary vessels, have been carried out at 25 patients with ischemia. These studies showed almost 100% of conformability with exposing the ischemia zones in scintigraphy and coronary arteriography in cases of coronary vessels contraction over 50%. The dipyridamole test also revealed the ischemzones in myocardium that are in agreement with coronary vascularization deficiency. That test can be utilized in revealing the coronary disease and is helpful in qualifying patients for coronary arteriography. At the same time studies that have been carried out prove that applying dipyridamole is absolutely contraindicated in treating of coronary disease of the organic background.

In 127 volunteers, serial rest-stress positron emission tomography scans using rubidium-82 with various adenosine infusion protocols identified (1) the protocol with maximum stress perfusion and CFR, (2) test-retest precision in same subject, (3) stress perfusion and CFR after adenosine compared with dipyridamole, (4) heterogeneity of coronary flow capacity combining stress perfusion and CFR, and (5) potential relevance for patients with risk factors or coronary artery disease. The adenosine 6-minute infusion with rubidium-82 injection at 3 minutes caused CFR that was significantly 15.7% higher than the 4-minute adenosine infusion with rubidium-82 injection at 2 minutes and significantly more homogeneous by Kolmogorov-Smirnov analysis for histograms of 1344 pixel range of perfusion in paired positron emission tomographies. In a coronary artery disease cohort separate from volunteers of this study, compared with the 3/6-minute protocol, the 2/4-minute adenosine protocol would potentially have changed 332 of 1732 (19%) positron emission tomographies at low-risk physiological severity CFR ≥2.3 to CFR <2.0, thereby implying high-risk quantitative severity potentially appropriate for interventions but because of suboptimal stress of the 2/4 protocol in some patients.

Several antiplatelet drugs (aspirin, sulfinpyrazone, hydroxychloroquine, dipyridamole, BL-3459, pyridinolcarbamate) were assayed for their ability to prevent the generalized Shwartzman reaction initiated by endotoxin in the pregnant rat, and compared to glucocorticoids (dexamethasone, hydrocortisone). The drugs were administered in a single large dose a few hours before provocation of the reaction. In opposition to glucocorticoids and beside BL-3459 which interfere with other mechanisms involved in the phenomenon, the tested inhibitors of platelet aggregation were found incapable of preventing or reducing the severity of the Shwartzman reaction.

The response rate was 11 to 14% for the i.v. push schedules and 21 to 36% for the 24-h continuous infusion regimens. The responses lasted for a median of 4.5 months and 12 months, respectively, if bolus or infusion schedules were applied. Median time to tumor progression was 4.5 months and 7 months for continuous infusion. The median patient survival was 10 to 12.7 months (bolus regimens) and 13 to 15 months for infusional 5-FU schedules.

Very low density lipoproteins (VLDL) and low density lipoproteins (LDL) were isolated from serum of hypercholesterolemic guinea-pigs, and the effect of these lipoproteins on guinea-pig platelets was studied. VLDL (greater than 100 microgram/ml) and LDL (greater than 400 microgram/ml) were found to cause aggregation of gel-filtered platelets (GFP), although the extent of GFP aggregation by LDL was smaller than that by VLDL. In platelet-rich plasma, however, lipoproteins could not induce platelet aggregation. VLDL and LDL even at the low concentrations at which lipoproteins alone could not induce aggregation potentiated ADP-induced aggregation of GFP. VLDL-induced aggregation of GFP was inhibited by apyrase (0.2--1.0 mg/ml) in a concentration-related manner. Prostaglandin E1, dipyridamole, potassium cyanide and ethylenediaminetetraacetic acid inhibited VLDL- and ADP-induced aggregation of GFP in the almost same degree. Inhibitions of VLDL-induced GFP aggregation by acetylsalicylic acid and albumin were slightly stronger than that of ADP-induced aggregation. These findings suggest that lipoproteins modulate platelets so that endogenous ADP can be released from platelets.

The modified base queuine is inserted posttranscriptionally into the first position of the anticodon of tyrosine tRNA, histidine tRNA, asparginine tRNA, and aspartic acid tRNA. Phorbol-12,13-didecanoate (PDD) effects a decrease in the queuine content of tRNA in cultured human foreskin fibroblasts. The present data suggest that this results from a PDD-mediated inhibition of queuine uptake. Nonsaturable uptake was observed for tritiated dihydroqueuine (rQT3) for up to 2 hr at 10 to 1000 nM concentrations, while saturation of uptake was observed after 3 to 4 hr. Lineweaver-Burke analysis of concentration versus uptake revealed biphasic uptake kinetics with high and low Km components of approximately 350 and 30 nM, respectively. Competition by queuine of rQT3 uptake indicated that both compounds have equal affinity for the uptake mechanism. PDD inhibited rQT3 uptake but required 30 to 60 min of exposure before the uptake was completely blocked. The rQT3 efflux rate from cells was found to be 3 to 4 times greater than that of uptake, and PDD also inhibited the efflux reaction. The potential inhibitors furosemide, nitrobenzylthioinosine, ouabain, 7-methylguanine, 7-deazaguanine, guanine, guanosine, adenine, adenosine, hypoxanthine, and epidermal growth factor had no effect on rQT3 uptake. However, dipyridamole was immediately effective at reducing rQT3 uptake.

Results of meta-analysis of 90 publications concerning cardiac stress-tests carried out to patients before operations on vessels and abdominal aorta are presented; 11,778 patients were included in the system review Diamox 250mg Tab Salt . On the basis of literary data advantages and disadvantages of diverse diagnostic tests and contra-indications to them were analyzed. Findings prove that pharmacological stress-tests have the highest sensitivity and specificity. Out of various diagnostic tests--treadmill test with ECG control, Holter monitoring, radioisotope imaging with thallium-201, and dipyridamole, and stress-echocardiography with dobutamine--the last one is the most informative in predective value of positive result, relative risk of possibility development of negative cardiac event (myocardial infarction or patient's death in consequence of myocardial infarction), likelihood ratio, sensitivity and specificity. Furthermore, during stress-echocardiography with dobutamine examination of myocardial contractility and evaluation of ejection fraction are available what makes it a method of choice in cardiac risk stratification in patients before reconstructive vascular surgery.

Dipyridamole thallium-201 tomographic imaging has good sensitivity (100%) in detecting esophagogastric mucosal erosions, but its poor specificity (33-57%) results in an unacceptable accuracy as a screening test. Additionally, the cost of radiopharmaceuticals requires that sensitivity and specificity be at least equal to that of endoscopy for this test to be clinically valuable as a screening test. However, a noninvasive test for these diseases is inherently appealing, and further research in this Bystolic 10 Mg Cost area seems to be warranted.

The human concentrative (Na(+)-linked) plasma membrane transport proteins hCNT1 and hCNT2 are selective for pyrimidine nucleosides (system cit) and purine nucleosides (system cif), respectively. Both have homologs in other mammalian species and belong to a gene family (CNT) that also includes hfCNT, a newly identified broad specificity pyrimidine and purine Na(+)-nucleoside symporter (system cib) from the ancient marine vertebrate, the Pacific hagfish (Eptatretus stouti). We now report the cDNA cloning and characterization of cib homologs of hfCNT from human mammary gland, differentiated human myeloid HL-60 cells, and mouse liver. The 691- and 703-residue human and mouse proteins, designated hCNT3 and mCNT3, respectively, were 79 Prevacid 45 Mg % identical in amino acid sequence and contained 13 putative transmembrane helices. hCNT3 was 48, 47, and 57% identical to hCNT1, hCNT2, and hfCNT, respectively. When produced in Xenopus oocytes, both proteins exhibited Na(+)-dependent cib-type functional activities. hCNT3 was electrogenic, and a sigmoidal dependence of uridine influx on Na(+) concentration indicated a Na(+):uridine coupling ratio of at least 2:1 for both hCNT3 and mCNT3 (cf 1:1 for hCNT1/2). Phorbol myristate acetate-induced differentiation of HL-60 cells led to the parallel appearance of cib-type activity and hCNT3 mRNA. Tissues containing hCNT3 transcripts included pancreas, bone marrow, trachea, mammary gland, liver, prostate, and regions of intestine, brain, and heart. The hCNT3 gene mapped to chromosome 9q22.2 and included an upstream phorbol myristate acetate response element.

Although cardiovascular disease (CVD) is a major source of morbidity and mortality in the United States, a relatively small percentage of deaths related to CVD result from ischemic stroke. However, the impairment and costs associated with stroke are large--and largely preventable. Large-scale trials have demonstrated benefit with antihypertensive therapy for secondary prevention, showing significantly reduced rates of stroke and cardiovascular events. Statins have shown efficacy in primary stroke prevention, and Megaslim Slimming Tablets one trial showed reduced incidence of stroke and cardiovascular events in patients with recent stroke or transient ischemic attack (TIA). The merits of antiplatelet therapy in primary and secondary stroke prevention have been demonstrated across numerous trials and meta-analyses. Trials assessing aspirin plus clopidogrel or aspirin plus extended-release dipyridamole for preventing secondary stroke have produced somewhat contradictory findings. This review discusses the relationship between CVD and risk of secondary stroke or TIA and summarizes secondary prevention strategies, focusing on antiplatelet agents, to provide guidance for the practicing cardiologist. Certain combination therapies appear to be more effective for secondary prevention of stroke or TIA than therapy with single antiplatelet agents. The choice of agents may be important, based on results of several trials. The ongoing, large-scale, comparative Prevention Regimen for Effectively Avoiding Second Strokes (PR. FESS) trial should provide cardiologists with more definitive recommendations.

NB1011, a novel anticancer agent, targets tumor cells expressing high levels of thymidylate synthase (TS). NB1011 is converted intracellularly to bromovinyldeoxyuridine monophosphate (BVdUMP) which competes with the natural substrate, deoxyuridine monophosphate, for binding to TS. Unlike inhibitors, NB1011 becomes a reversible substrate for TS catalysis. Thus, TS retains activity and converts BVdUMP into cytotoxic product(s). In vitro cytotoxicity studies demonstrate NB1011's preferential activity against tumor cells expressing elevated TS protein levels. Additionally, NB1011 has antitumor activity in vivo. To identify drugs which interact synergistically with NB1011, we screened 13 combinations of chemotherapeutic agents with NB1011 in human tumor and normal cells. Dipyridamole and p-nitrobenzylthioinosine (NBMPR), potent inhibitors of equilibrative nucleoside transport, synergized with NB1011 selectively against 5-fluorouracil (5-FU)-resistant H630R10 colon carcinoma cells [combination index (CI)=0.75 and 0.35] and Tomudex-resistant MCF7TDX breast carcinoma cells (CI=0.51 and 0.57), both TS overexpressing cell lines. These agents produced no synergy with NB1011 in Det551 and CCD18co normal cells (CI > 1.1) lacking TS overexpression. Dipyridamole potentiated NB1011's cytotoxicity in medium lacking nucleosides and bases, suggesting a Buy Generic Cialis 20 Mg non-salvage-dependent mechanism. We demonstrate that nucleoside transport inhibitors, dipyridamole and NBMPR, show promise for clinically efficacious combination with NB1011.

A prospective, double-blind clinical study was performed to evaluate the combination of dipyridamole 225 mg/day and acetylsalicylic acid 1 gm/day prophylaxis of postoperative venous thromboembolism in elective total hip replacement. Patients were stratified according to age, and randomly assigned to receive drug or placebo. All patients were followed with 125I-labeled fibrinogen scanning for one week postoperatively, or until fully mobile. Venography was performed in 79/132 patients; in 36 patients the Bystolic Medication Information venogram was obtained to confirm a positive fibrinogen scan, in 43 patients an elective venogram was obtained on the seventh postoperative day to evaluate the operated thigh (a blind area for scanning). Thrombosis (by scan or venogram) was found in 17/68 (25%) in the control group, and in 23/64 (36%) in the treated group. Overall incidence was 40/132 (30%). Correlation of scan with venography was 90%. There were no clinically significant pulmonary emboli in either group. The combination of acetylsalicylic acid (ASA) and dipyridamole as given in this study is not effective prophylaxis in elective total hip replacement.

The agents used for nuclear stress testing (NST) including adenosine, dobutamine, and dipyridamole, are generally well tolerated and the incidence of serious complications associated with their use in NST is relatively low. Adenosine possesses a potent inhibitory effect on the atrioventricular (AV) node and may induce a transient conduction defect which could result in first-, second-, or third-degree heart block in some patients. The use of the potent AV nodal blocker adenosine for nuclear stress testing in patients with evidence of underlying conduction system disease may result in serious complications. We present the case of a 79-year-old man who had sustained second-degree AV block requiring permanent pacemaker implantation following adenosine infusion for nuclear stress testing. We also review the literature regarding the association between adenosine NST and AV block.
