OBJECTIVES To determine whether proton magnetic resonance spectroscopy (MRS), a newer radiographic technology, would be useful in the evaluation of the thalamus of patients in vegetative states resulting from traumatic brain injury. METHODS 14 victims of severe traumatic brain injury who were in the vegetative state and whose magnetic resonance images of the thalamus were normal underwent bil...

Colletotrichum orbiculare is the causative agent of anthracnose disease on cucurbitaceous plants. Several signaling pathways, including cAMP-PKA and mitogen-activating protein kinase (MAPK) pathways are involved in the infection-related morphogenesis and pathogenicity of C. orbiculare. However, upstream regulators of these pathways for this species remain unidentified. In this study, CoIRA1, en...

In an effort to elaborate the elements of actinidia micropropagation methodology, 2 varieties male form
 (Kamandor, Pryvabny) and female form (Sentyabrskaya, Prevoshodnaya) were selected. The shoot tips forms
 buds lignified shoots forms used as initial explants. regenerative ability explants at stage in vitro culture induction was defined by plant genotype type explant selected: expl...

Vegetative propagule pressure may affect the establishment and structure of aquatic plant communities that are commonly dominated by plants capable of clonal growth. We experimentally constructed aquatic communities consisting of four submerged macrophytes (Hydrilla verticillata, Ceratophyllum demersum, Elodea nuttallii and Myriophyllum spicatum) with three levels of vegetative propagule pressu...

Plant architecture is commonly defined by the adjacency of organs within the structure and their properties. Few studies consider the effect of endogenous temporal factors, namely phenological factors, on the establishment of plant architecture. This study hypothesized that, in addition to the effect of environmental factors, the observed plant architecture results from both endogenous structur...

sand dune habitats in desert regions have harsh conditions for plant establishment and survival. ammodendron persicum, an psamophyte shrub plant belongs to leguminosae family, which grows over the desert sand dunes of zirkohgaen, gezik and khash  along east part of iran. recognizing the adaptive features of the plant species may help towards its conservation and introducing to other sand dune h...

Quantitative transmission electron microscopy was used to study pore density (mean pore number ± standard deviation/nuclear envelope area) on developing pollen nuclei of alfalfa. We found that pore density is essentially uniform around the vegetative nucleus (VN) at an early developmental stage (29 ±6 pores fan'), but later, •when the VN forms a close physical association with the generative ce...

1. The vegetative forms of amebae may be developed in vitro from the cysts. 2. The cysts of Entamoeba tetragena and Entamoeba coli each produce only a single vegetative individual. It has not been observed in vitro that a number of daughter amebae, corresponding to the number of nuclei present in the cyst, emerge from the mother cyst, as claimed by Casagrandi and Barbagallo, Schaudinn, and a nu...
