Here, we show that the polyamine spermidine plays a key role as a morphogenetic determinant during spermatid development in the water fern Marsilea vestita. Spermidine levels rise first in sterile jacket cells and then increase dramatically in spermatogenous cells as the spermatids mature. RNA interference and drug treatments were employed to deplete spermidine in the gametophyte at different s...

The objective of this study was to evaluate the cytotoxicity potential of aqueous extracts of Nepeta cataria, Fumaria indica, Borago officinalis, Adiantum capillus, Levandula stoeches on HeLa cell line. Leaves of plants were washed with distilled water, dried in shade, grinded to fine powder and stored in airtight container at room temperature in the dark until used. The powdered samples were s...

BACKGROUND This paper presents the first quantitative ethnobotanical study of the flora in Toli Peer National Park of Azad Jammu and Kashmir, Pakistan. Being a remote area, there is a strong dependence by local people on ethnobotanical practices. Thus, we attempted to record the folk uses of the native plants of the area with a view to acknowledging and documenting the ethnobotanical knowledge....

The aim of the present study was to investigate the anti-rheumatoid activity of secondary metabolites produced by endophytic mycobiota in Egypt. A total of 27 endophytic fungi were isolated from 10 dominant medicinal plant host species in Wadi Tala, Saint Katherine Protectorate, arid Sinai, Egypt. Of those taxa, seven isolates of Chaetomium globosum (CG1-CG7), being the most frequent taxon, wer...

Ayoola G.A. et al 3 used four medicianal plants ie, leaves of carica papaya Linn, stem bark of magnifera Indica Linn, leaves of Psidium guagava used in the treatment of malaria. One of the major reasons for the development of anemia in malaria seems to be oxidative stress. The immune system of the body is activated by infections, including malaria, thereby causing the release of reactive oxygen...
