Ultrasound assisted meth...

The cytotoxicity of the biomaterials is a key issue that should be addressed prior to pre-clinical applications. This study was designed to evaluate and compare the cytotoxixity of two forms of bioactive glasses:nanopowder:andmicropowder. Human HGF1-PI53 gingival fibroblast cells were used to evaluate the cytotoxicity of 0.5, 1, 1.5, 2, 5, 10, 15 and 20 mg/mL concentrations of the two bioactive...

Nano Bioactive glass material of the type CaO–P2O5–SiO2 was obtained by the sol-gel processing method at considerably lower temperatures than required for conventional melting methods. As a new modification, volume of solution was changed in order to investigate its effects on the properties of bioglass samples. The obtained material was characterized by X-ray powder diffraction (XRD), surface ...

Green algae as one of the marine natural resources which is included in main seaweed found many coastal areas In-donesia. The bioactive component that acts an antibacterial agent green type Ulva lactuca ulvan polysaccharide extract. Ulvan a cell wall accounts for 9-36% dry weight biomass and mainly composed rhamnose sulfate, uronic acid (glucuronic iduronic acid) xylose. Polysaccharide extracte...

Caffeic acid phenethyl ester (CAPE) is a bioactive component isolated from propolis. A series of CAPE analogues was synthesized and their antiradical/antioxidant effects analyzed. The effect of the presence of the double bond and of the conjugated system on the antioxidant effect is evaluated with the analogues obtained from 3-(3,4-dihydroxyphenyl) propanoic acid. Those obtained from 2-(3,4-di...

Biochemical processes are gaining industrial importance because of their inherent advantages like mild operating conditions and versatility of the processes which mean lower operating costs in terms of lesser energy requirements and a number of industrially important products that could be made from a general process setup. These features have made the biochemical processes the target of intens...

We investigated the interwire distance dependence on the growth kinetics of vertical, high-yield InAs nanowire arrays on Si 111 grown by catalyst-free selective area molecular beam epitaxy MBE . Utilizing lithographically defined SiO2 nanomasks on Si 111 with regular hole patterns, catalyst-free and site-selective growth of vertically 111 -oriented InAs nanowires was achieved with very high yie...

The use of natural excipients to deliver the bioactive agents has been hampered by the synthetic materials. However advantages offered by these natural excipients are their being non-toxic, less expensive and freely available. The performance of the excipients partly determines the quality of the medicines. The traditional concept of the excipients as any component other than the active substan...
