This study evaluated the shear bond strength of different repair systems to nickel-chromium (NiCr) alloy after storage in water for either 24 hours or six months. One hundred cylindrical specimens (3 mm thick x 9 mm diameter) were fabricated using an NiCr alloy and embedded in a PVC ring, where they received one of five bonding and resin composite repair(More)
Neocarzinostatin (NCS) used for the chemotherapy of leukemia and cancers such as stomach, pancreas and bladder, has been pointed out to have the side effects mainly causing leukopenia. In order to prevent these side effects of NCS by systemic administration, we have attempted to inject NCS directly into the tumor tissues and to inactivate NCS leaked from(More)
1. Effects of inhibitors in the haemolymph from three silkworms on proteases from the alimentary canal of respective insects were studied as well as those on bovine trypsin and alpha-chymotrypsin. 2. In Bombyx haemolymph, three inhibitor fractions were separated by gel filtration on Sephadex G-75. These fractions differed in the specificity of inhibition(More)
STATEMENT OF PROBLEM Although titanium presents attractive physical and mechanical properties, there is a need for improving the bond at the titanium/luting cement interface for the longevity of metal ceramic restorations. PURPOSE The purpose of this study was to evaluate the effect of surface treatments on the shear bond strength (SBS) of resin-modified(More)
PURPOSE To evaluate the effect of surface treatments on the shear bond strength (SBS) of a resin cement to commercially pure titanium (CP Ti). MATERIALS AND METHODS Two hundred cast CP Ti disks were divided into 5 groups (n = 40), which were treated with one of the following air-abrasion techniques: (1) 50-µm Al2O3 particles; (2) 120-µm Al2O3 particles;(More)
Investigation of the effectiveness of surface treatments that promote a strong bond strength of resin cements to metals can contribute significantly to the longevity of metal-ceramic restorations. This study evaluated the effect of surface treatments on the shear bond strength (SBS) of a resin cement to commercially pure titanium (CP Ti). Ninety cast CP Ti(More)
This study evaluated the shear bond strength (SBS) and stability of commercially pure titanium (CP Ti)/repair material interfaces promoted by different repair systems. One hundred CP Ti cast discs were divided into five repair system groups: 1) Epricord (EP); 2) Bistite II DC (BT); 3) Cojet (CJ); 4) Scotchbond Multi-Purpose Plus (SB) (control group); and 5)(More)
STATEMENT OF PROBLEM A strong and durable bond between a metal framework and a resin-based luting agent is desired. Metal primers have been shown to be very effective on noble alloys. However, there is insufficient information about their effect on base metals. PURPOSE The purpose of this study was to evaluate the effect of metal primers on the shear bond(More)
