Bioactivity-guided Study of Passiflora caerulea L. Leaf Extracts
Passiflora species were known by their anticonvulsant, anxiolytic and sedative activities. The aim of this study was to investigate the chemical composition of the most active leaf extract of Passiflora caerulea L. grown in Egypt. The ethanolic extract of the leaves exhibited higher activity than aqueous extract as anticonvulsant (63% potency relative to carbamazepine), analgesic (70% potency r...
متن کاملDeformable Spectrograms
Speech and other natural sounds show high temporal correlation and smooth spectral evolution punctuated by a few, irregular and abrupt changes. In a conventional Hidden Markov Model (HMM), such structure is represented weakly and indirectly through transitions between explicit states representing ‘steps’ along such smooth changes. It would be more efficient and informative to model successive s...

متن کاملAchyranthes Aspera Leaf Extracts Inhibited Fungal Growth
The aim of the study was investigate antifungal activity of the various leaves extracs of Achyranthes aspera Linn.The aqueous,ethanol and methanol leaves extracts of Achyranthes aspera Linn. (Family:Amaranthaceae) were evaluated for antifungal activity against clinically important fungal spp viz. Candida albicans (MTCC 227), C.tropicalis (MTCC 750), C.krusei (ATCC 6258), C.kefyr (ATCC 4235), C....
متن کاملPhase-Encoded Speech Spectrograms
Spectrograms of speech and audio signals are time-frequency densities, and by construction, they are non-negative and do not have phase associated with them. Under certain conditions on the amount of overlap between consecutive frames and frequency sampling, it is possible to reconstruct the signal from the spectrogram. Deviating from this requirement, we develop a new technique to incorporate ...
