Apoptosis in metazoans is often accompanied by the destruction of DNA replication initiation proteins, inactivation of checkpoints and activation of cyclin-dependent kinases, which are inhibited by checkpoints that directly or indirectly require initiation proteins. Here we show that, in the budding yeast Saccharomyces cerevisiae, mutations in initiation proteins that attenuate both the initiat...

Budding hydromedusae have high reproductive rates due to asexual reproduction and can occur in high population densities along the coasts, specifically in tidal pools. In laboratory experiments, we investigated the effects of population density on the survival and reproductive strategies of a single clone of Eleutheria dichotoma. We found that sexual reproduction occurs with the highest rate at...

abstract persian walnut is one of the most important nut crops in iran. now the majority of orchards are seedling with a great diversity. for establishing uniform orchards and increasing the quantity and quality of yield, patch budding as the most suitable propagation methods, have still technical and practical problems in the country. in spite of high percent of primary success in patch buddin...

Stationary phase cultures of Candida albicans inoculated into fresh medium at 37 degrees C synchronously from buds at pH 4.5 and mycelia at pH 6.5. During bud formation, a filament ring forms just under the plasma membrane at the mother cell-bud junction at roughly the time of evagination. A filament ring also forms in mycelium-forming cells, but it appears later than in a budding cell and it i...

introduction between oil seeds, from the quality, quantity and nutrition index point of view, canola has the top level . because of the solubility of n fertilizers, the time of urea application, is very important and one of the main reasons of the reduction in n application efficiency is utilization of urea in an inappropriate time. by precisely foliar application of nitrogen, the efficiency of...

UNLABELLED The presence of "tumour budding", ie. single cancer cells, or a nest of poorly- differentiated cells at the front of invasion, in bowel cancer appears to be a new histopathological indicator of increased aggressiveness of colorectal carcinoma. The aim of this work was a retrospective evaluation of the front of invasion in preoperative biopsies of patients with rectal carcinoma (T1) a...

BACKGROUND Bro1 domains are elongated, banana-shaped domains that were first identified in the yeast ESCRT pathway protein, Bro1p. Humans express three Bro1 domain-containing proteins: ALIX, BROX, and HD-PTP, which function in association with the ESCRT pathway to help mediate intraluminal vesicle formation at multivesicular bodies, the abscission stage of cytokinesis, and/or enveloped virus bu...
