Plasmodium vivax can cause severe malaria, however its pathogenesis is poorly understood. In contrast to P. falciparum, circulating vivax parasitemia is low, with minimal apparent sequestration in endothelium-lined microvasculature, and pathogenesis thought unrelated to parasite biomass. However, the relationships between vivax disease-severity and total parasite biomass, endothelial autocrine ...
Abstract In this experiment, the effect of the arbuscular mycorrhizal fungi (AMF) Glomus mosseae and G. etunicatum on root colonization, plant growth and nutrient uptake, chlorophyll content (a, b, total and cartenoid) and carbohy-drate content were studied in six genotypes of mint (Mentha spicata L.) in pots. The AM inoculation significant-ly increased the fresh and dry weight of sh...
The biomass supplier selection problem is characterized by a high degree of uncertainty because of subjective preferences/evaluations of decision makers, raw material cost fluctuations, variations in biomass seasonality and the dynamics of biomass demand. Designing a biomass supply chain often becomes a time-dependent problem that should be addressed by examining adequate supply schemes in diff...
Plant lignin is one of the major wall components that greatly contribute to biomass recalcitrance for biofuel production. In this study, total 79 representative Miscanthus germplasms were determined with wide biomass digestibility and diverse monolignol composition. Integrative analyses indicated that three major monolignols (S, G, H) and S/G ratio could account for lignin negative influence on...
Nine additive allometric equations for computing above-ground, standing biomass were developed for the plant community and for each of 18 single species typical of the Tamaulipan thornscrub of north-eastern Mexico. Equations developed using additive procedures in seemingly unrelated linear regression provided statistical efficiency in total biomass estimates at the scales of both individual spe...
Climate change is known as one of the most important environmental challenges. Sequestration of carbon in terrestrial ecosystems is a low-cost option that may be available in the near-term to mitigate increasing atmospheric CO2 concentrations, while providing additional benefits. In this study, we estimated the effects of planting density and grazing intensity on the potential of Atriplex canes...
In order to evaluate the response of rice genotypes to salinity stress, 16 rice genotypes were assessed to 4 salinity levels (0, 4, 8, 12, dS/m) through a split plot experiment based on completely randomized design at germination stage .Germination percentage, germination rate, length of radicle, length of shoot, radicle dry weight, shoot dry weight, total biomass, and total radicle-shoot weigh...
macrobentos frequency and biomass was investigated in the gorgan bay in 2011. five sampling sites were chosen to collect benthos and sediment from the bay using a van veen grab sampler. samples were collected seasonally. macrobenthos were indentified and their biomass was recorded. sediment heavy metals concentration were measured using atomic absorption spectroscopy. a total of 11 families bel...
