We isolated and characterized As-resistant endophytic bacteria (AEB) from two arsenic hyperaccumulators. Their plant growth promoting traits and the relation between As tolerance and transformation were evaluated. A total of 41 and 33 AEB were isolated from Pteris vittata (PV) and Pteris multifida (PM) respectively. PV AEB represented 2genera while PM AEB comprised of 12 genera, with Bacillus s...

We propose a conceptual framework for restoration of threatened plant species that encourages integration of technological, ecological, and social spheres. A sphere encompasses ideas relevant to restoration and the people working within similar areas of influence or expertise. Increased capacity within a sphere and a higher degree of coalescing among spheres predict a greater probability of suc...

Rhythmic spontaneous bursting is a fundamental hallmark of the immature hippocampal activity recorded in vitro. These bursts or giant depolarizing potentials (GDPs) are GABA- and glutamatergic-driven events. The mechanisms of GDPs generation are still controversial, since although a hilar origin has been suggested, GDPs were also recorded from isolated CA3 area. Here, we have investigated the o...

BACKGROUND Prenatal protein malnutrition disrupts the pattern of maturation and development of the hippocampus and its neuroanatomy and increases inhibition of the granular cell layer of the fascia dentata. If local gamma-aminobutyric acid inter-neurons are partly responsible for inhibition of the hippocampus, it is reasonable to assume that there may be an increase in the gamma-aminobutyric ac...

Ixeris dentata var. albiflora is considered as a potential therapeutic agent against mithridatism, calculous, indigestion, pneumonia, hepatitis, and tumors as well as good seasoned vegetable in Far East countries. Phytoene synthase (PSY), phytoene desaturase (PDS) ξ-carotene desaturase (ZDS), lycopene β-cyclase (LCYB), lycopene ε-cyclase (LCYE), ε-ring carotene hydroxylase (CHXB), and zeaxanthi...

ETHNOPHARMACOLOGICAL RELEVANCE People living in the tropical rain forest of South-Western Nigeria use Rinorea dentata (P. Beauv.) Kuntze (Violaceae) in ethno-veterinary medicine to facilitate parturition. There are no evidence-based pharmacological investigations for the uterotonic activity of this plant. AIMS OF STUDY (i) Collection of data about the ethnopharmacological uses of R. dentata a...

The southern Neotropical genus Anahi Martínez is comprehensively revised and now includes three species: A. dentata Ocampo Ruiz-Manzanos new species, A. guaraniticus Martínez, and A. oblivia Ocampo Ruiz-Manzanos new species. The new species extend the distribution of the genus from Paraguay and Bolivia to Argentina. A. guaraniticus is redescribed and the characters that define the genus are ext...

Intensive botanical exploration of the Marquesas Islands (French Polynesia) for the Vascular Flora of the Marquesas Islands and Flore de la Polynésie française projects has resulted in numerous additional new collections from these islands. Study of these collections has brought to light 11 new species of pteridophytes (ferns and lycophytes) which are described herein: Blechnum pacificum Lorenc...
