ABSTRACTImmunotherapy has significantly advanced the field of oncology in recent decades. Understanding normal immunosurveillance, as well as the ways in which tumor cells have evolved to evade it, has provided the knowledge for development of drugs that allow one’s own immune system to target and destroy malignant cells (immunotherapy). Cutaneous malignancies are particularly sensitive to this class of drugs. In a very sensitive anatomic region such as the periocular tissue, where surgical excision may come with significant morbidity, this technology has had a strong impact in the successful treatment of historically challenging tumors. 相似文献

ObjectiveThe current study aimed at examining a fluoride containing bioactive glass (BiominF®) paste as a temporary filling material capable of remineralizing the demineralized enamel or dentin, and its ability to decrease a simulated dentinal fluids pressure on the resin/dentin interface, without affecting the shear bond strength of a universal bonding agent to enamel and dentin.Methods60 premolars were utilized for the acid resistance, trans-microradiography (TMR) and shear bond strength (SBS) experiments. Enamel and dentin discs were demineralized for 4 days to create a subsurface demineralized zone followed by applying BiominF® paste, 1.23% acidulated phosphate fluoride, or a temporary filling material for 24 h.30 extracted human non-carious third molars were utilized for the pulpal pressure experiment in which direct communication to the pulp chamber was created by cutting at a level approximately 1 mm below the cemento-enamel junction while the coronal enamel was ground to expose mid coronal dentin. The dentin surface was exposed to a simulated pulpal pressure. The dentin surfaces had BiominF® paste, an oxalate desensitizing agent, or temporary filling material followed by application of a universal adhesive system.ResultsOne way ANOVA showed that BiominF® paste remineralized effectively the demineralized enamel or dentin, did not affect the bond strength of the enamel and dentin surfaces to the tested adhesive system p < 0.05, and improved the acid resistance of the demineralized enamel and dentin against a secondary erosive challenge. Moreover, BiominF® paste decreased the nanoleakage expression in the dentin/adhesive interface exposed to a simulated pulpal pressure.SignificanceBiominF® paste may serve as a temporary filling material that may improve the longevity of adhesive restorations and help to conserve tooth structures by preserving the demineralized enamel and dentin form cutting during cavity preparation. 相似文献

Long-term care (LTC) physical and psychosocial mealtime environments have been inconsistently assessed due to the lack of a standardized measure. The purpose of this study was to examine the construct validity of a new standardized observational measure, the Mealtime Scan (MTS), using the Making Most of Mealtimes data collected on 639 residents in 82 dining rooms in 32 LTC homes. The MTS includes physical, social, and person-centered care summary scales scored from 1 to 8. Mean ratings on these summary scales were moderate for physical (5.6 SD 0.9), social (5.0 SD 0.9), and person-centered care (PCC; 5.5 SD 0.8). Regression analyses determined which items within the MTS were associated with these summary scales: physical – music (B?=?0.27, p?=?0.04), number of staff passing food (B?=??0.11, p?=?0.03), number of residents (B?=??0.03, p?=?0.01); social – social sound (B?= 0.31 p?0.0001), number of residents requiring eating assistance (B?=?0.11, p?=?0.02); PCC – lighting (B?=?0.01 p?=?0.04), and total excess noise (B?=?0.05, p?0.0001). The Mealtime Relational Care Checklist (M-RCC) was associated positively with ratings on all three summary scales. Correlations revealed that the MTS summary scales were associated with other constructs: Dining Environment Audit Protocol functionality scale, resident and dining room level M-RCC, Mini Nutritional Assessment- Short Form, and resident Cognitive Performance Scale. These results demonstrate that the MTS summary scales exhibit construct validity, as the ratings were associated with expected observed mealtime characteristics and correlated with dining room and resident level constructs in anticipated directions. 相似文献

Insufficient recovery after injury of a peripheral motor nerve is due to (1) inappropriate pathfinding as a result of axonal regrowth to inappropriate targets, (2) excessive collateral axonal branching at the lesion site, and (3) polyinnervation of the neuromuscular junctions (NMJs). The rat facial nerve model is often used because of its simple and reliable readout to measure recovery of function (vibrissal whisking). Over the last decades scientists have concentrated their efforts to combat mostly NMJ polyinnervation, because it turned out to be very difficult to reduce collateral axonal branching and impossible to navigate thousands of axons toward the original fascicles. In the past, several groups of scientists concentrated their efforts to reduce the activity-dependent polyinnervation of NMJs by electrical stimulation of the muscles (square 0.1 msec pulses at 5 Hz). The results showed no recovery of functions and a severe reduction in the number of innervated NMJs to approximately one fifth of those observed in intact animals. More recent experiments, however, have shown that motor recovery improved significantly following mechanical stimulation of the denervated facial muscles (vibrissal and orbicularis oculi) and that restored functions could invariably be linked to reduced polyinnervation at the NMJ while the number of innervated NMJ remained the same. These results suggest that clinically feasible and effective therapies could be developed and tested in the near future. Anat Rec, 302:1287–1303, 2019. © 2019 Wiley Periodicals, Inc. 相似文献

This review summarises all head and neck oncology and related papers published in the British Journal of Oral and Maxillofacial Surgery (BJOMS) during the period 2009-2010. A similar review, covering the years 2007-2008 was published in the Journal in 2009 and was well received by readers, as evidenced by the high number of downloads from the BJOMS website. In this article, we include all head and neck oncology-related articles published in the print version of the journal during 2009/10 and concentrate on summarising the full length article papers. Compared to the previous 2-year period, there has been a 25% increase in number of articles published in this sub-specialty. 相似文献

Acrylic resins are widely used in the fabrication of denture bases and have been shown to be cytotoxic as a result of substances that leach from the resin. The primary eluate is residual monomer. Numerous reports suggest that residual monomer may be responsible for mucosal irritation and sensitization of tissues. This information is important, not only to assess the biologic effects of such materials, but also to enable a comparison among the different polymerization methods, thus assisting the clinician in selecting a material with minimal cytotoxicity. This article reviews the literature published from 1973 to 2000, selected by use of a Medline search, associated with cytotoxic effects usually ascribed to acrylic denture base materials. 相似文献
