Studies on genetic diversity help us to unveil the evolutionary processes of species and populations and can explain several traits of diploid-polyploid complexes such as their distributions, their breeding systems, and the origin of polyploids. We examined the allozyme variation of Dryopteris aemula and D. oreades, diploid ferns with highly fragmented habitats, and the allotetraploid D. corley...

Multi agent systems (MAS) are popularly used in practice, however; a few studies have looked at MAS capabilities from the power engineering perspective. This paper presents the results of an investigation concerning the compatibility of MAS capabilities in different power engineering categories. Five MAS capabilities and seven power system categories are established. A framework for applying MA...

In this paper, we introduce a novel approach based on higher order energy functions which have the ability to encode global structural dependencies to infer articulated 3D spine models to CT volume data. A personalized geometrical model is reconstructed from biplanar X-rays before spinal surgery in order to create a spinal column representation which is modeled by a series of intervertebral tra...

Dans le cadre de son plan d’élimination de la transmission de la mère à l’enfant du VIH , le Sénégal a adopté depuis 2012 l’option B+ de l’OMS consistant en une mise sous trithérapie systématique des femmes enceintes séropositives, associée à l’allaitement maternel et la mise sous prophylaxie antirétrovirale (ARV) de leurs nourrissons. L’objectif de notre étude était d’étudier les risques de tr...

Diffuse neonatal hemangiomatosis (DNH) is characterized by multiple capillary or cavernous hemangiomas on the skin and internal organs occurring during the neo­ natal period. It is a life­threatening condition due to high­output heart failure with a mortality rate of 60­85% without proper treatment. The areas that are most commonly involved include the skin (100%), liver (64­100%), and central ...

The global burden of cancer continues to increase largely with the aging and growth of the world population. The purpose of the present work was to find new anticancer molecules from a natural source. We utilized chromatographic methods to isolate compounds from medicinal plant Dryopteris fragrans (L.) Schott. The structure of the new compounds was determined by spectroscopic and spectrometric ...

That Pteris aquilina, a spccies of fern, destroys thiamine, or possesses "anti thiamine activity" or "antianeurine factor" has been reported by Weswig (1), Thomas (2) and Evans (3). Similar factors, though somewhat weaker in activity, have also been found in Aspidium filix mas, Dryapteris austriaca and Nephrolepsis exaltata by Somogyi (4, 5, 6) and in Equisetum arvense by Evans et al. (7). Acco...

Dopp (1) demonstrated that the extract from mature prothalli of the fern species Ptcridiwtn1 aquiilinunil (L.) Kuhln hastened the onset of antheridium formation in young prothalli of this species by several days and in the prothalli of Dryopteris filixwwlas (L). Schott by several weeks. Dopp's conclusion that the prothalli of P. aquilinit elaborate a specific antheridium-inducing factor was con...
