Plants undergo two major post-embryonic developmental transitions--the juvenile-to-adult vegetative transition (vegetative phase change) and the adult-to-reproductive transition (flowering). In woody plants, these transitions can be separated by years, but in herbaceous species they are often very close together, making it difficult to differentiate the effects of vegetative phase change and fl...

OBJECTIVES To establish the prevalence of vegetative state in Dutch nursing homes, describe the patient characteristics, and highlight the possible influence of medical decisions at the end of life. DESIGN A cross-sectional survey. The vegetative state was defined according to the Multi Society Task Force on PVS. All Dutch nursing homes were approached to provide data on patients in a vegetat...

Clostridium perfringens vegetative cells cause both histotoxic infections (e.g., gas gangrene) and diseases originating in the intestines (e.g., hemorrhagic necrotizing enteritis or lethal enterotoxemia). Despite their medical and veterinary importance, the molecular pathogenicity of C. perfringens vegetative cells causing diseases of intestinal origin remains poorly understood. However, C. per...

Transition from vegetative cells to aerial mycelium and spores of Streptomyces collinus is accompanied by changes in the pattern of proteins phosphorylated. Preparation from spores exhibits lower phosphorylation activity than those of vegetative cells and aerial mycelium. Phosphorylation of proteins from aerial mycelium was markedly stimulated by the presence of Mn2+. Our data indicate that pho...

endocarditis is rarely reported in sheep and information presented for ovine endocarditis is based mostly on comparative findings in the cattle. infective vegetative endocarditis of the right heart was diagnosed in a 3-year-old fat-tailed ram. clinical findings included tachycardia, marked brisket edema, jugular veins distention and pulsation and pale mucous membranes. hematologic abnormality i...

The changes in the syntheses of macromolecules that accompany sporulation of Bacillus subtilis have been the subject of several recent reports. In brief, the available data show that as a rapidly growing culture of B. subtilis departs from strict logarithmic growth, the net synthesis of RNA is abruptly arrested although the protein and DNA content approximately double after that time.' De novo ...

The vegetative state may develop suddenly (as a consequence of traumatic or non-traumatic brain injury, such as hypoxia or anoxia; infection; or haemorrhage) or gradually (in the course of a neurodegenerative disorder, such as Alzheimer’s disease). Although uncommon, the condition is perplexing because there is an apparent dissociation between the two cardinal elements of consciousness: awarene...

Long-term potentiation (LTP) is a form of activity-dependent plasticity that occurs during learning. Potassium channels are the most diverse group of all ion channels that related to synaptic plasticity. Small-conductance calcium-activated potassium channels (SKs) are found in hippocampal CA1 neurons and by inhibiting of postsynaptic potentials are involved in synaptic transmission impairment. ...

Sir, Pyoderma gangrenosum (PG) is a sterile, pustular, ulcerative process of unknown cause (1). It is frequently associated with various systemic diseases, including inflammatory bowel disease, arthritis, monoclonal gammopathy, malignant disease (2) and, rarely, Behçet’s disease (3). Four clinical and histological variants have been recognized: ulcerative, pustular, bullous and vegetative. Vege...
