Astragalus hamosus and corniculatus were examined for the presence of flavoalkaloids, acylated highly glycosylated flavonoids. Non-purified extracts overground parts species subjected to ultra-high performance liquid chromatography – high resolution electrospray ionisation mass spectrometry (UHPLC-HRESIMS) analysis results compared authentic reference substances. A flavoalkaloid kaempferol was ...

BACKGROUND Biering-Sørenson (1984) found that individuals with less lumbar extensor muscle endurance had an increased occurrence of first episode low back pain. As a result, back endurance tests have been recommended for inclusion in health assessment protocols. However, different studies have reported markedly different values for endurance times, leading some researchers to believe that the b...

In order to understand the bioaccumulation of essential metals in filter-feeding mollusks living in soft sediments, the uptake and depuration kinetics of three elements (Co, Mn and Zn) were investigated in the king scallop Pecten maximus exposed via seawater, food, or sediment, using radiotracer techniques. The scallops were collected in April 2005 in the Pertuis Breton, France and acclimated t...

The phylogeny of symbiotic genes of Astragalus glycyphyllos L. (liquorice milkvetch) nodule isolates was studied by comparative sequence analysis of nodA, nodC, nodH and nifH loci. In all these genes phylograms, liquorice milkvetch rhizobia (closely related to bacteria of three species, i.e. Mesorhizobium amorphae, Mesorhizobium septentrionale and Mesorhizobium ciceri) formed one clearly separa...

Introduction. Pastures are the primary source of food in livestock systems and can be a suitable niche for insects with beneficial harmful functions. Objective. To estimate entomofauna associated three species pastures, Cenchrus ciliaris, Chloris gayana, Megathyrsus maximus, conditions Colombian Caribbean. Materials methods. Ten samplings were carried out two contrasting periods (August to Octo...

Several introduced African grasses are known to present recurring patterns of invasiveness and cause a severe impact on the diversity functioning ecosystems worldwide. Megathyrsus maximus (Guinea grass), forage grass species native South Africa, is reported be highly invasive pose serious threat biodiversity in range. Despite ecological threats posed by M. worldwide, there dearth information ag...
