OBJECTIVES An experimental rabbit model was used to test the null hypothesis, that there is no difference in new bone formation around uncoated titanium discs compared with coated titanium discs when implanted into the muscles of rabbits. METHODS A total of three titanium discs with different surface and coating (1, porous coating; 2, porous coating + Bonemaster (Biomet); and 3, porous coatin...

OBJECTIVES The shear bond strength of three glass ionomer cements (GIC) to enamel and dentine was evaluated. STUDY DESIGN Sound permanent human molars (n=12) were grinded perpendicular to their axial axes, exposing smooth, flat enamel and dentine surfaces. The teeth were embedded in resin and conditioned with polyacrylic acid (25%; 10s). Twenty four specimens of each GIC: Fuji IX (FJ-GC), Ket...

Background: The anti-inflammatory, antioxidant, antiviral, antibacterial, antitumor, antiarthritic, and anti-diabetic properties of aloe vera has been well documented in the literature. Considering its antibacterial evaluating benefits as mouth rinse oral diseases may facilitate patients getting cheaper safer herbal remedy to clean their cavities. Objective: To evaluate Antibacterial efficacy a...

Neem (Azadirachta indica) and Tamarind (Tamarindus leaves are used worldwide for their wide range of medicinal properties like antibacterial, antiprotozoal, hepato-protective other properties. The present study was conducted to observe the effects as anthelmintics in cattle. Animals were selected grouped into four groups where Group A considered control, B treated with grinded leaves,...

BACKGROUND Moringa oleifera belongs to plant family, Moringaceae and popularly called "wonderful tree", for it is used traditionally to cure many diseases including cancer in Africa and Asia, however, there is limited knowledge on cytotoxic activity of Moringa oleifera seeds on MCF7 breast cancer cell. The present study evaluated antiproliferative effect on MCF7 of the seed. MATERIALS AND MET...

BACKGROUND The galvanic coupling intra-body communication has low radiation and strong anti-interference ability, so it has many advantages in the wireless communication. METHOD In order to analyze the effect of muscle tissue's characteristics upon the communication channel, we selected the muscle of pig buttock as the experimental sample, and used it to study the attenuation property with th...

PURPOSE The aim of this study was to evaluate the effect of paracetic acid (PAA) and ozone disinfection on the tensile bond strength (TBS) of silicone-based resilient liners to acrylic resins. MATERIALS AND METHODS One hundred and twenty dumbbell shaped heat-polymerized acrylic resins were prepared. From the mid segment of the specimens, 3 mm of acrylic were grinded off and separated parts we...

A method of direct lipid analysis by MALDI mass spectrometry in intact membranes, without prior extraction/separation steps, is described. The purple membrane isolated from the extremely halophilic archaeon Halobacterium salinarum was selected as model membrane. Lyophilized purple membranes were grinded with 9-aminoacridine as dry matrix and the powder mixture crushed in a mechanical die press ...

Structurally different carbon materials with an increasing sp2/sp3 ratio were synthesized by pyrolizing cellulose materials at 400, 600, 800 and 1000 oC . The hybridization ratios and the internal structures in these sampleswere determined by using High Resolution Transmission Electron Microscopy, Electron Energy Loss Spectroscopy, Raman spectroscopy, IR spectroscopy and elemental combustion an...

The potential use of water hyacinth dry matter for removing heavy metals from wastewater is studied by combining various spectroscopic techniques and quantum chemical ab initio calculations. The aquatic plant water hyacinth was treated with 0.025, 0.050, 0.100, 0.200, and 0.400 M acetic acid for different times up to 19.0 hours. The plant was divided into root and shoot then dried and grinded i...
