When stained by using an indirect fluorescent-antibody technique, Methylosinus trichosporium displayed an uneven fluorescence. Exospores and the polar tips of some vegetative cells displayed a more intense fluorescence than the other cells. Cross-absorption of the specific anti-M. trichosporium immunoglobulin G with exospores resulted in no fluorescence of exospores or exospore regions of sporu...
The objective of this study was to determine the integrity of the homoeostatic coupling relationship between neuronal electrical function and cerebral metabolism in the vegetative and minimally conscious states. Ten patients who met recognised diagnostic criteria (six in the vegetative state and four minimally conscious) were investigated using simultaneous electroencephalography and positron e...
In double fertilization, the vegetative cell of the male gametophyte (pollen) germinates and forms a pollen tube that brings to the female gametophyte two sperm cells that fertilize the egg and central cell to form the embryo and endosperm, respectively. The 5-methylcytosine DNA glycosylase DEMETER (DME), expressed in the central cell, is required for maternal allele demethylation and gene impr...
Although the general observation that the longer the duration of the vegetative state, the lower the probability of emerging from it remains true, reports of late improvement are ever more common in the literature. The aim of this study was to verify evolution from Vegetative State in a group of inpatients in a Neurorehabilitation facility and to identify the parameters increasing the likelihoo...
The repair of deoxyribonucleic acid (DNA) in germinating spores was studied in comparison with that in vegetative cells. Radiation-induced single-strand breaks in the DNA of spores and of vegetative cells of Bacillus subtilis were rejoined during postirradiation incubation. The molecular weight of single-stranded DNA was restored to the level of nonirradiated cells. The rate of the rejoining of...
fruit yield efficiency and some vegetative characteristics of commercial and spur type apple. cultivars was evaluated in dr. nakhjavani field station, orumieh, iran, in 2008 and 2009 growing seasons. apple cultivars included: red spur, red chief, golden spur, yellow spur, fujii, red delicious, cooper spur, red cooper spur, jonathan, golden delicious, oregon spur, jonagold. the experimental desi...
Washed vegetative cells of Bacillus mycoides obtained and treated under specified conditions have been found to sporulate when shaken in distilled water under specified conditions. Within limitations of the methods, a heat-resistant cell (spore) is produced for each heat-sensitive vegetative cell present initially. Several different experiments designed to detect massive lysis and cell growth d...
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...

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...
