The lipophilicity of a series of Schiff base ligands and their complexes with nickel(II) and copper(II) has been determined by reversed-phase thin-layer chromatography using binary dioxane-water mobile phase. Chelate ligands were prepared by condensation of diamine and the corresponding beta-diketone. Copper(II) and nickel(II) complexes with chelate ligands containing ethane-1,2-diamine or prop...

Both genetic and musical sequences are ordered structures composed of combinations of a small number of elements, of nucleotides and musical notes. In the case of the genome, the emergence of cellular functions makes the order meaningful; in the case of musical sequences, the consequence of order is the production of mysterious esthetical effects in the human mind. Can any musical significance ...

Coleus aromaticus Benth (Lamiaceae) is known as a must-have plant in medicinal herb garden. The plant is well known for its antimicrobial and pharmacological activities. It is also reported to possess antioxidant and food additive properties. Antioxidant activity is reported to be mainly due to rosmarinic acid, chlorogenic acid and caffeic acid. The essential oil of Coleus aromaticus has great ...

The yeast Ipi3p is required for DNA replication and cell viability in Sacharomyces cerevisiae. It is an essential component of the Rix1 complex (Rix1p/Ipi2p-Ipi1p-Ipi3p) that is required for the processing of 35S pre-rRNA in pre-60S ribosomal particles and for the initiation of DNA replication. The human IPI3 homolog is WDR18 (WD repeat domain 18), which shares significant homology with yIpi3p....

In this article a hydrodynamic and rheological analysis of a continuous airlift bioreactor with high-cell-density system is presented. A highly flocculating recombinant strain of Sacharomyces cerevisiae containing genes for lactose transport (lactose permease) and hydrolysis (beta-galactosidase) was exploited to ferment lactose from cheese whey to ethanol. The magnetic particle-tracer method wa...

ABSTRACTUtilization of the hawaiian papaya fruit or local name “bird papaya” which is processed into fermented drinks (fruit wine) one way to increase added value and usefulness fruit. One alternative processing technologies for by cooking "Overripe" has potential be developed manufacture obtained fermentation. The production can done through alcoholic fermentation process juice. This run with ...

Peroxisomes have a central function in lipid metabolism, including the beta-oxidation of various fatty acids. The products and substrates involved in the beta-oxidation have to cross the peroxisomal membrane, which previously has been demonstrated to constitute a closed barrier, implying the existence of specific transport mechanisms. Fatty acid transport across the yeast peroxisomal membrane m...
