This paper uses the Continued Fraction Expansion (CFE) method for analog realization of fractional order differ-integrator and few special classes of fractional order (FO) controllers viz. Fractional Order Proportional-Integral-Derivative (FOPID) controller, FO[PD] controller and FO lead-lag compensator. Contemporary researchers have given several formulations for rational approximation of frac...

Analysis of viral RNA encapsidation assay provides a rapid means of assaying which of the progeny RNA are competent for packaging into stable mature virions. Generally, a parallel analysis of total RNA and RNA obtained from purified virions is advisable for accurate interpretation of the results. In this, we describe a series of in vivo assays in which viral RNA encapsidation can be verified. T...

Olive mill wastewaters (OMW) are rich in water-soluble polyphenolic compounds that show remarkable antioxidant properties. In this work, the recovery yield of compounds, such as hydroxytyrosol and tyrosol, as well as total phenols (TPh) from real OMW was investigated. Antioxidants were recovered by means of liquid-liquid solvent extraction. For this purpose, a laboratory-scale pilot unit was es...

It has been demonstrated that the presence of cancer results in detectable changes to uninvolved tissues, collectively termed cancer field effects (CFE). In this study, we directly assessed the ability of Raman microspectroscopy to detect CFE via in-vitro study of organotypic tissue rafts approximating human skin. Raman spectra were measured from both epidermis and dermis after transfer of the ...

Natural products in Chonnam, Korea were screened via anti-angiogenesis experiments, and 1 candidate product was identified, Corni fructus, which exerted dose-dependent inhibitory effects against angiogenesis, adipogenesis, and cell adhesion. C. fructus extract (CFE) exhibits an angiogenesis inhibitory effect superior to that of the EGCG from green tea leaves. The expression level of angiogenesi...

Leaves of Tabernaemontana divaricata extracts in petroleum ether, ethanol chloroform, methanol and aqueous were analyzed for their phytochemical screening. Qualitative quantitative analysis was performed to identify the presence various phytoconstituents with standard procedures. The Alkaloids, Glycosides, Flavonoids, Diterpenes, Phenol, Proteins, Carbohydrate, Saponins Tannins. For estimation ...

CFE-1 is a unique plasmid-encoded AmpC β-lactamase with the regulator gene ampR. It imparts high resistance to most cephalosporins with constitutive high-level β-lactamase activity. Here, the β-lactamase activities and expression levels of ampC with or without ampR were investigated. Results suggested that the resistance of CFE-1 to cephalosporins is caused by a substitution in AmpR, in which t...
