ObjectiveThe purpose of this laboratory study is to evaluate the application of a pre-sintered surface augmentation to zirconia (Zir) and lithium disilicate (LDS) ceramics on the delamination strength of adhesive resin cement. The applied surface augmentation was the ruling of lines to the pre-sintered surface of the ceramics.MethodsNinety milled Zir and sixty pressed LDS specimens (3 mm × 0.5 mm × 25 mm) were created and divided into five groups (n = 30). Group 1: Zir no surface treatment (control Zir-NT); Group 2: Zir airborne particle abraded (Zir-APA) with 30 μm CoJet; Group 3: Zir pre-sintered surface augmentation (Zir-SA); Group 4: LDS etched (control LDS-etched) and; Group 5: LDS with pre-sintered surface augmentation and etching (LDS-SA). A resin adhesive cement (3 mm × 1 mm × 8 mm) was then applied and cured to the ceramic specimens. The delamination strength values of the resin cement from the ceramic were recorded. The delamination strength data were analysed statistically using one-way ANOVA and Turkey post hoc analysis.ResultsThe mean delamination strength and standard deviation, when comparing only the Zir-SA to the resin cement were statistically different (p < 0.001); Zir-SA 63.42 ± 11.85, Zir-NT 26.82 ± 12.07, and Zir-APA 48.11 ± 17.85 MPa. Comparison between LDS groups were not significantly different (p = 0.193); LDS-etched 33.49 ± 16.07 and LDS-SA 28.83 ± 10.15 MPa. The delaminated Weibull modulus was highest for surface augmentation Zir specimens (m = 13.56) but decreasing to less than half for Zir-APA (m = 6.27) and Zir-NT (m = 5.68). The Weibull values for the LDS-SA and LDS-etched specimens was 5.63 and 3.38 respectively.SignificanceIncorporating the pre-sintered surface augmentation to zirconia improved the delamination strength and reliability of Zir to the resin cement but not for LDS. 相似文献

The authors report a case of a dorsal dislocation of the fifth metatarsophalangeal joint that could not be reduced by closed manipulation, and instead required open reduction with Kirschner-wire fixation to maintain alignment. Although metatarsophalangeal joint dislocation is not unheard of, it is not common for the deformity to resist efforts at closed reduction and immobilization or percutaneous pin fixation. One year after surgery, the patient described in this article had returned to his baseline activity level, and was ambulating without pain while demonstrating full range of motion in the fifth metatarsophalangeal joint. 相似文献

Introduction
Cystatin C could be a relevant residual glomerular filtration rate marker during hemodialysis (HD), and a high cytokine plasma (p) rate is associated with an increase in mortality during sepsis. To the best of our knowledge, cytokines and cystatin C kinetics during and after HD during sepsis have never been studied. In this study, we described p cytokines and cystatin C variations during and after hemodialysis in septic-shock patients with acute kidney injury (AKI). 相似文献105.

INTRODUCTION: This retrospective study analyses causes as well as clinical, immunological and virological consequences of antiretroviral treatment interruptions (Ti) of more than 30 days in HIV-1 infected adults. METHODS: This causes were classified as related to drug toxicity, therapeutic or adherence failure. We studied therapeutic regimens before Ti and after treatment reinitiation (TR), clinical events related to Ti, CD4 cells and viral loads before Ti and at months 3, 6, 9, and 12 after TR. RESULTS: Out of 188 Ti analysed, 42.6% were related to therapeutic failure, 33.5% to drug toxicity, and 23.9% to adherence failure. Eight Aids defining clinical events were reported during Ti, in patients with low CD4 cells and high viral load (P < 0.05). Viral loads evolution after TR was better if Ti was related to treatment failure (P < 0.05), was prolonged (P < 0.05), and if CD4 cells were high before Ti and at TR (P < 0.05). Median CD4 cells was of 296/mm(3) at month 12 after TR vs 382 before Ti. CONCLUSIONS: Ti consequences are strongly related to CD4 cells, which decrease sharply during Ti, increasing Aids defining events probability. Prospective randomised clinical studies are needed to define usefulness of Ti. 相似文献

Objective
The aim of this study was to investigate the correlation between levels of depression symptoms and age, thyroid-stimulating hormone levels, and stressful life events of the participants.Method
Patients above 18 years old, with any thyroid disorders, and without psychiatric disorders were included in this study. All participants completed the Depression Anxiety Stress Scale 21 (DASS-21). The depression symptom score was calculated and interpreted as follows: less than 9: no depression; between 10 and 13: mild depression; between 14 and 20: moderate depression; between 21 and 27: severe depression, and more than 28: extremely severe depression.Results
The total number of participants in this study was 199. There was no correlation between age, thyroid stimulating hormone, and the DASS score. There was also no significant difference in the DASS-21 score between genders. However, there was a positive correlation between depression symptoms and stressful life events (r = 0.201, n = 199, p < 0.05).Conclusions
These findings would suggest that increased depression symptom scores correlate with increased stressful life events. A larger study should be undertaken to confirm these findings. 相似文献108.

Frequent loss of heterozygosity (LOH) and mutations of the tumor suppressor gene PTEN (phosphatase and tensin homologue deleted from chromosome 10) have been found in sporadic gliomas. The most documented regions of allelic losses include 9p21, 10q23-25 and 17p1 3 whereas PTEN aberrations are preferentially found in glioblastoma multiformes. This research aimed to detect the incidence of allelic losses on chromosomes 10q, 9p, 17p and 13q and mutations on exons 5, 6 and 8 of PTEN in malignant gliomas. Malignant glioma specimens obtained were classified histopathologically according to the WHO criteria. Each tumor was then subjected to polymerase chain reaction (PCR)-LOH analysis using microsatellite markers and single-stranded conformational polymorphism (SSCP) analysis. Twelve of 23 (52%) malignant glioma cases showed allelic losses whereas 7 of 23 (30%) samples showed aberrant band patterns and mutations of PTEN. Four of these cases showed LOH in 10q23 and mutations of PTEN. The data on LOH indicated the involvement of different genes in the genesis of glioma whereas mutations of PTEN indicated the role of PTEN tumor suppressor gene in the progression of glioma in Malay population. 相似文献
