The aim of this study is to compare the metallic and natural fiber reinforced polymer composite bone plates used in humerus fractures. A 3D finite element model was developed to analyze the performance of both types of plates. This study proposed on fabrication of natural fiber powdered material (like Sisal (Agave sisalana), Banana (Musa sapientum) and Roselle (Hibiscus sabdariffa)) Reinforced ...

A smpile, rapid and accurate method for the determination of main mono and divalent inorganic anions in Roselle (Hibiscus sabdariffa L.) has been developed. The quantitative determination of anions F-, Cl-, NO2, Br ,NO3, HPO 24,SO 24, and I was accomplished by suppressed conductimetric ion chromatography (IC). The separation is achieved on shim-pack IC-SA2 250 mmL X 4.0 mm ID Peak. column opera...

In this study, the forty Thai medicinal plants were used to screen the antibacterial activity against Campylobacter jejuni. Crude 95% ethanolic extracts of each plant were prepared. Antibacterial activity was investigated by the disc diffusion assay, and MICs and MBCs were determined by broth microdilution. The results of antibacterial screening showed that five plants have activity against C.j...

The antioxidant bioactivities of the whole isolated anthocyanins from Hibiscus sabdariffa (HS) calyx were evaluated and compared with the bioactivity of vitamin C as a standard water soluble antioxidant vitamin. They were assessed for antioxidant activity based on their ability to impair 2, 4-dinitrophenylhydrazine (DNPH)-induced oxidative tissue damage in toxicant exposed rabbits. Exposure of ...

According to reports, Candida albicans is believed to be the leading cause of fungal urinary tract infections, otherwise known as Candiduria. Prevention of candiduria using natural products is desirable and should be investigated. The current study reports the antimicrobial effect of H. sabdariffa (Roselle) extract, a common herbal drink, in combination with voriconazole or fluconazole against ...

Natural colorants have been widely used in food and cosmetic products. Nonionic and anionic surfactants are also usually added as solubilizers and stabilizers in the products. Surfactants form a special structure, a so-called micelle. Micelles can alter stabilities and physicochemical properties of other chemicals in the system. The objectives of this study were to determine stabilities in mice...
