The aim of this in vitro study was to compare the microleakage of Er:YAG laser and diamond bur on different bonding systems in class V restorations. Class V cavities were prepared with Er:YAG laser or diamond bur on 80 intact human molars. Teeth were randomly distributed into ten groups and cavities were restored with CeramX duo (DENTSPLY) or Filtek Silorane (3M/ESPE) using different bonding materials (One Coat 7.0 (Coltène), XP Bond (DENTSPLY), Clearfil Protect Bond (Kuraray), AdperSE (3M/ESPE), and Silorane System Adhesive (3M/ESPE). All specimens were subjected to thermocycling and load cycling. After being immersed in silver nitrate dye, the specimens were sectioned. Microleakage was evaluated by stereomicroscope and SEM. Data were statistically analyzed by one-way ANOVA, Kruskal-Wallis, and Mann-Whitney tests. Statistically differences were found between groups (p > 0.05) and cavities prepared with the Er:YAG laser showed higher microleakage than diamond bur. The microleakage of different bonding systems was influenced by the choice of diamond bur or Er:YAG laser for class V composite cavity preparation. 相似文献

There are several side effects which have been reported during the infusion of peripheral blood progenitor cells (PBPCs) either due to the infusion or the content of the infusate. We have evaluated the side effects detected during PBPCs infusion in 194 autologous and 25 allogeneic transplantations. In autologous cryopreserved PBPCs infusion, we detected a total of forty-nine (25.25%) side effect events during and after the infusion period. Forty-six (23.71%) of these side effects were detected during the infusion period including fifteen (7.73%) cardiac side effects, which required stopping the infusion, and thirty-one (15.97%) non-cardiac side effects, which did not require cessation of the infusion. Sinus bradycardia after a minimum of 45 min after completing the infusion was seen in three (1.54%) patients. The median volume, dimethyl sulfoxide (DMSO) and total nucleated cell (TNC) content of the product were found to be significantly higher in patients with side effects compared to the group without any side effects (P<0.05). The median volume and DMSO content were found to be significantly higher in patients with cardiac side effects compared to non-cardiac side effects (P<0.05). There was no cardiac side effects in patients treated with an infusate containing 100 x 10(9) L(-1) leukocytes. We did not observe any infusion-related side effects in patients given allogeneic non-cryopreserved PBPCs. We have concluded that the volume, DMSO and TNC content of autologous cryopreserved PBPCs product are directly related to clinical side effects. 相似文献

BACKGROUND: Chronic myocardial ischaemia due to coronary artery stenosis or occlusion has been shown to increase the growth of coronary collateral circulation. Collateralization leads to increased oxygen delivery to the area at risk and hence may reduce ischaemia, prevent infarction and preserve contractile function. However, there is considerable variation among patient subsets in terms of the presence or degree of collateralization. We aimed to evaluate the relationship between obesity and coronary collateral development in patients with ischaemic heart disease. METHODS AND RESULTS: In all, 215 patients (mean age, 57.8+/-8.9 y) with body mass index (BMI)> or =30 kg/m(2) were enrolled into our study. A total of 90 age- and sex-matched patients (mean age, 58.7+/-10 y) with BMI<25 kg/m(2) and significant coronary artery disease were selected as a control group. The mean age and distribution of risk factors for coronary heart disease were not significantly different between two groups other than poorer HDL cholesterol and triglyceride profile in obese patients. The mean BMI was significantly higher in the patient group (33.3+/-2.4 vs 22.8+/-1.7, P<0.001). The mean number of diseased vessels and maximum lesion severity were not significantly different between the two groups. The mean Rentrop collateral score of the patient group was significantly worse than the control group (1.08+/-0.68 vs 2.10+/-0.72, P<0.001). CONCLUSIONS: Our findings suggest that collateral vessel development is poorer in obese patients (defined as BMI> or =30 kg/m(2)) with ischemic heart disease compared to normal range BMI, and the risk of having poor collateral vessel development is significantly increased. However, this might be reflecting the cluster of risk factors, associated with metabolic syndrome, in which insulin resistance plays a major role. 相似文献

Ruxolitinib was well tolerated and superior to best available therapy (including interferon [IFN]) in controlling hematocrit without phlebotomy eligibility, normalizing blood counts, and improving polycythemia vera-related symptoms in the Study of Efficacy and Safety in Polycythemia Vera Subjects Who Are Resistant to or Intolerant of Hydroxyurea: JAK Inhibitor INC424 (INCB018424) Tablets Versus Best Available Care (RESPONSE) studies. This ad hoc analysis focuses on ruxolitinib in relation to IFN in the RESPONSE studies, with attention on the following: (1) safety and efficacy of ruxolitinib and best available therapy in patients who received IFN before study randomization, (2) safety and efficacy of IFN during randomized treatment in best available therapy arm, and (3) use of ruxolitinib after crossover from best available therapy in IFN-treated patients. IFN exposure before randomization had little effect on the efficacy or safety of ruxolitinib. In the randomized treatment arms, ruxolitinib was superior to IFN in efficacy [hematocrit control (RESPONSE?=?60% of ruxolitinib vs 23% of IFN patients; RESPONSE-2?=?62% of ruxolitinib vs 15% of IFN patients)] and was tolerated better in hydroxyurea-resistant or hydroxyurea-intolerant patients. After crossing over to receive ruxolitinib, patients who had initially received IFN and did not respond had improved hematologic and spleen responses (62% of patients at any time after crossover) and an overall reduction in phlebotomy procedures. Rates and incidences of the most common adverse events decreased after crossover to ruxolitinib, except for infections (primarily grade 1 or 2). These data suggest that ruxolitinib is efficacious and well tolerated in patients who were previously treated with IFN. The RESPONSE (NCT01243944) and RESPONSE-2 (NCT02038036) studies were registered at clinicaltrials.gov. 相似文献

Coronary steal due to an unligated side branch of the internal mammary artery graft is a rare but important pathology causing ischaemia. We describe the case of a patient with significant ischaemia having an unligated side branch of the left internal mammary artery after coronary artery bypass surgery and who underwent coil embolization of the side branch. 相似文献
