The aim of this study was to elucidate the mechanism of the healing process mediated by the flavonic fraction of Bidens aurea on chronic gastric ulceration induced by 5% acetic acid in rats. The diethyl ether extract (125 and 62.5 mg kg-1 body weight) was administered in a single doses, 7 and 14 days after provocation of lesions. Our results demonstrated that both doses significantly decreased ...

Prompt detection of declines in abundance or distribution of populations is critical when managing threatened species that have high population turnover. Population monitoring programs provide the tools necessary to identify and detect decreases in abundance that will threaten the persistence of key populations and should occur in an adaptive management framework which designs monitoring to max...

The aim of this paper is to present recent advances in the microbotanical analyses an organic residue on a potsherd from late Holocene hunter-gatherer site Argentine Patagonia, which first evidence kind for processing starchy food. Standard methods were carried out starch grain recovery and morphometric analysis, care being taken prevention cross-contamination evaluation post-depositional facto...

Abstract ?-Fe 2 O 3 nanoparticles were synthesized using Tabebuia aurea leaf extract by a facile approach. The signature peaks for Fe and in the EDX spectrum verified formation of nanoparticles. Cuboidal-shaped observed FE-SEM image. In XRD pattern, it was that belong to These particles pure crystalline with an average particle size 25.69 nm. signals at 538 494 cm ?1 FTIR image confirmed hemati...

Torbangun (Coleus amboinicus Lour) has been used as a breast milk stimulant (a lactagogue) by Bataknese people in Indonesia for hundreds of years. However, the traditional use of torbangun is not well documented, and scientific evidence is limited to establish coleus as a lactagogue. This Focus Group Discussion (FGD) study was conducted to gather information regarding the practice and cultural ...

In the framework of the correlation between chemotaxonomy and chemical analysis studies, the chemical composition of the essential oils of four varieties of Thuja species cultivated in Poland - T. occidentalis 'globosa', T. occidentalis 'aurea', T. plicata and T. plicata 'gracialis' - were investigated by GC and GC-MS. Thirty-one compounds were identified from T. occidentalis 'globosa', represe...

During an investigation of Trentepohliales (Ulvophyceae) from tropical areas in China, four species of the genus Phycopeltis were identified: Phycopeltis aurea, P. epiphyton, P. flabellata and P. prostrata. The morphological characteristics of both young and adult thalli were observed and compared. Three species (P. flabellata, P. aurea and P. epiphyton) shared a symmetrical development with di...
