results phylogenetic analysis of the partial ns5b region demonstrated the relatedness of isolate fsm165 to the new subtype reported from iran in 2006. moreover, some core/e1 and ns5b sequences that had a high level of similarity with fsm165 isolate were found through searching the hcv database. these sequences were previously either misclassified or could not be accurately classified. phylogene...

Total phenolic content and antioxidative properties of Taraxacum officinale leaves and flowers extract was studied. Extracts was made with different solvents: classical organic and surfactant solutions. The results showed that all examined extracts contain some polyphenols and have antioxidant potential against DPPH radical and reducing power (Fe3+ Fe2+). Leaf extracts made with organic solvent...

Using the field pot-culture and sample-analysis method, 54 weed species belonging to 20 families and 31 weed species belonging to 17 families were systematically examined as to whether they can exclude the uptake of heavy metals. After a systematic identification, it was determined that Oenothera biennis and Commelina communis were Cd-excluders and Taraxacum mongolicum was a Zn-excluder. O. bie...

Extract of Taraxacum platycarpum (AF-343) has been reported to have several biological properties such as skin hydration and anti-inflammatory effects. Although clinical evidences of skin hydration and antiinflammatory effect were proven in clinical trial, precise mechanism of skin hydration was not fully understood yet. In this study, we have focused skin hydration mechanism related filaggrin,...

background and objectives: petroleum hydrocarbons are harmful to the environment, human health, and all other living creatures. oil and its byproducts in contact with water block sunshine to phytoplanktons and thus break the food chain and damage the marine food source. this study aims to isolate the crude oil degrading and biosurfactant producing bacteria from the oil contaminated soils of gac...

321 honey samples from Switzerland were collected. The botanical authenticity of 176 honey samples was confirmed by the determination of electrical conductivity, sugar composition, pH-value, free acidity, and microscopical pollen analysis [2], as well as the sensory evaluation by three experts. The honey samples were assigned to one of the following groups: floral honeys from acacia (Robinia sp...

uricase or urate oxidase (urate:oxygen oxidoreductase, ec 1.7.3.3), a peroxisomal enzyme which is found in many bacteria, catalyzes the oxidative opening of the purine ring of urate to yield allantoin, carbon dioxide, and hydrogen peroxide. in this study, the phylogeny of urate oxidase (uricase) producing bacteria was studied based on gene sequences of 16s rrna and uricase protein. representati...

The notion of a Persistent Phylogeny generalizes the well-known Perfect phylogeny model that has been thoroughly investigated and is used to explain a wide range of evolutionary phenomena. More precisely, while the Perfect Phylogeny model allows each character to be acquired once in the entire evolutionary history while character losses are not allowed, the Persistent Phylogeny model allows eac...
