Limnocharis flava is an edible wetland plant, whose phenolic acid and flavonoid compositions as well as bioactivities were underexplored. This study analyzed the profiles of selected hydroxybenzoic acids, hydroxycinnamic acids and flavonoids in the aqueous extracts of L. flava leaf, rhizome and root by high performance liquid chromatography (HPLC). Anti-lipoxygenase and antioxidant (iron chelat...

Abstract: On the basis of the materials obtained from the studies carried out from 2000 to 2015, we present the data on distribution of the Yellow Wagtail forms in the north of Western Siberia, i.e. within the overlapping boundaries of the ranges of a complex set of several polytypical forms – Motacilla flava sensu lato. Four forms have been identified here: two forms from the group of Western ...

This study describes the seasonal distribution of larvae, nymph, and adult life stages for 3 species of ixodid ticks collected by tick drag and sweep methods from various habitats in the Republic of Korea (ROK). Grasses less than 0.5 m in height, including herbaceous and crawling vegetation, and deciduous, conifer, and mixed forests with abundant leaf/needle litter were surveyed at United State...

Ticks were collected from 35 animals from 5 provinces and 3 metropolitan cities during 2012. Ticks also were collected by tick drag from 4 sites in Gyeonggi-do (2) and Jeollabuk-do (2) Provinces. A total of 612 ticks belonging to 6 species and 3 genera were collected from mammals and a bird (n=573) and by tick drag (n=39). Haemaphyalis longicornis (n=434) was the most commonly collected tick, f...

BACKGROUND Head or anterior body part regeneration is commonly associated with protostome, but not deuterostome invertebrates. However, it has been shown that the solitary hemichordate Ptychodera flava possesses the remarkable capacity to regenerate their entire nervous system, including their dorsal neural tube and their anterior head-like structure, or proboscis. Hemichordates, also known as ...

Switchgrass, Panicum virgatum L., is a perennial warm-season grass that has been identified as a model species for the development of bioenergy crops in the United States. The objectives of this research were to evaluate selected switchgrass populations for host suitability and differential resistance to potential aphid pests, determine the categories (antibiosis, antixenosis, and/or tolerance)...

The chemopreventive properties of the herbal teas rooibos (Aspalathus linearis) and honeybush (Cyclopia spp.) have been demonstrated on mouse skin in vivo but the underlying mechanisms are not clear. The aim of the current study was to determine the anti-proliferative and pro-apoptotic activity of methanol and aqueous extracts of rooibos and two Cyclopia species in different skin cells, using g...

The Yellow Wagtail, Motacilla flava Linnaeus, Motacillidae (Passeriformes : Aves) is a slender 15 16 cm long bird that inhabits open country near water such as wet meadows. Cytological investigation depicted the diploid chromosome count between 78 and 85 with 80 as modal value. No structural uncertainty was observed between macroand microchromosomes. Z W were fourth in order of size, both sub-m...

The activity of methacycline against microbial L-forms and their parent bacteria was compared with that of oxytetracycline, chlortetracycline, tetracycline, and demethylchlortetracycline, as well as with that of 22 other antibiotics which included examples of major groups of antibiotics. The L-forms and bacteria used were Streptococcus faecalis, S. faecium, S. faecalis var. zymogenes, Staphyloc...

The increasing global demand for petroleum oils has led to a significant increase in their cost and the search renewable alternative waste resources biodiesel synthesis production using novel environmentally sound acceptable methods. In current study, Kocuria flava lipase was immobilized on Fe3O4/cellulose nanocomposite; used as biocatalyst conversion of cooking oil wastes into through transest...
