PURPOSE The aim of this study was to evaluate the effects of 4 mouth rinses on the color stability of two different resin composites. MATERIALS AND METHODS A2 shade sonic-activated bulk fill material SonicFill (Kerr) and conventional nanohybrid composite Filtek Z550 (3M ESPE) were used. Forty disc-shaped specimens (10 mm x 2 mm) were fabricated for both composites and finished using 400-grit ...
BACKGROUND Each year almost one million newborns die from infections, mostly in low-income countries. Timely case management would save many lives but the relative mortality effect of varying strategies is unknown. We have estimated the effect of providing oral, or injectable antibiotics at home or in first-level facilities, and of in-patient hospital care on neonatal mortality from pneumonia a...
In situ forming Si-HA/BCP are potent injectable bone substitutes to regenerate defects.
BACKGROUND More than 40 million women use injectable contraceptives to prevent pregnancy, and most current or previous injectable users report being satisfied with the method. However, while women may find injectables acceptable, they may not always find them accessible due to stock-outs and difficulties with returning to the clinic for reinjections. FHI 360 is spearheading efforts to develop a...
Background and purpose: The use of bioactive glass-ceramics in medicine has been noticed because of their ability in directly connection to bony tissue and bone repairing. Chitosan is also nontoxic material and biologically is compatible with the capability of biodegradation. However, due to the minimally invasive nature of injectable systems and their ability to make scaffold in place of using...
Abstract Hydrogels have been extensively favored as drug and cell carriers for the repair of knee cartilage defects. Recruiting mesenchymal stem cells (MSCs) in situ to defect region could reduce risk contamination during delivery, which is a highly promising strategy enhance repair. Here, cell-free tissue engineering (TE) system was developed by applying an injectable chitosan/silk fibroin hyd...
The number of commercially available injectable soft tissue fillers has increased dramatically over the past decade. In the United States, a variety of temporary fillers have received Food and Drug Administration (FDA) approval. However, at the present time, there are no permanent soft tissue injectable fillers available. This article will discuss the authors' experience with some of the more p...
A total of 197 multidose injectable vials were collected from 10 different nursing stations and evaluated for sterility. Experimental contamination studies were undertaken, and the cost-effectiveness of multidose vials was compared with that of single-dose vials. Our results showed that bacterial contamination of multidose injectable vials was not a significant hazard; in addition, contrary to ...
Injectable Hydrogels In article number 2101284 by Chien-Chi Lin and co-workers, a biocompatible pH/thermo dual responsive injectable hydrogel is synthesized reversible addition-fragmentation chain-transfer (RAFT) polymerization acylhdrazone click chemistry. Upon injection, sol-gel transition occurs rapidly at body temperature the porous hydrogels degrade slowly under mild acidic condition due t...
IMPORTANCE After multiple sclerosis (MS) relapse while a patient is receiving an injectable disease-modifying drug, many physicians advocate therapy switch, but the relative effectiveness of different switch decisions is often uncertain. OBJECTIVE To compare the effect of the oral immunomodulator fingolimod with that of all injectable immunomodulators (interferons or glatiramer acetate) on re...
