One important area for which little experimental evidence is available is the snowgrass country. There is a strong body of opinion that in the snowgrass the combined effects of fire and grazing have been responsible for deterioration in vegetative cover and stability. It seems likely that changes in the boundari~s between the snowgrass and fescue communiti~s have been due to, or aggravated by, ...

Elimination of Clostridium difficile spores from the clinical setting requires stringent application of infection control procedures including the use of hard-surface disinfectants. A unique combination of sodium taurocholate together with amino acids has been reported as an alternative approach to potentially eliminating spores of C. difficile by increasing their sensitivity to common disinfec...

Proteus mirabilis causes serious kidney infections which can involve invasion of host urothelial cells. We present data showing that the ability to invade host urothelial cells is closely coupled to swarming, a form of cyclical multicellular behavior in which vegetative bacteria differentiate into hyperflagellated, filamentous swarm cells capable of coordinated and rapid population migration. E...

Ultrastructural features of embryogenic pollen in Datura innoxia are described, just prior to, during, and after completion of the first division of the presumptive vegetative cell. In anther cultures initiated towards the end of the microspore phase and incubated at 28 degrees C in darkness, the spores divide within 24 h and show features consistent with those of dividing spores in vivo. Cytok...

Vegetative growth of four different strains of Hericium erinaceus was observed. The temperature suitable for optimal mycelial growth was determined to be 25℃, with growth observed in the extend temperature range of 20~30℃. The different strains of this mushroom showed distinct pH requirements for their optimum vegetative growth, with the most favorable growth observed at pH 6. Considering veget...

Polycomb group (PcG) protein-mediated gene silencing is a major regulatory mechanism in higher eukaryotes that affects gene expression at the transcriptional level. Here, we report that two conserved homologous PcG proteins, RING1A and RING1B (RING1A/B), are required for global H2A monoubiquitination (H2Aub) in Arabidopsis. The mutation of RING1A/B increased the expression of members of the SQU...

Modifications of the fatty acid composition of plant vegetative tissues produce deficient plant growth. To determine the expression of the seed high-saturated sunflower (Helianthus annuus L.) mutant character during the vegetative cycle, five sunflower mutant lines (three high-stearic and two high-palmitic) have been studied during their germination and vegetative cycle. No significant variatio...

The genetic basis of vegetative incompatibility in the cellular slime mold, Dictyostelium discoideum, is elucidated. Vegetatively compatible haploid strains from parasexual diploids at a frequency of between 10(-6) and 10(-5), whereas "escaped" diploids are formed between vegetatively incompatible strains at a frequency of approximately 10(-8). There is probably only a single vegetative incompa...

BACKGROUND Having a patient in a vegetative state in the family is a complicated and stressful experience. Caring for such patients with complete disability at home is very challenging. OBJECTIVES The present study aimed to explore the outcomes of caring for patients in a vegetative state for families and caregivers at home. PATIENTS AND METHODS In this qualitative study, 16 vegetative pati...
