BACKGROUND The budding yeast Saccharomyces cerevisiae can bud in two spatially programmed patterns: axial or bipolar. In the axial budding pattern, cells polarize and divide adjacent to the previous site of cell separation, in response to a cell-division remnant, which includes Bud3p, Bud4p and septin proteins. This paper investigates the role of an additional component of the cell-division rem...

Both sex allocation and sexual conflict can be modulated by spatial structure. However, how the interplay between type of dispersal scale competition simultaneously affects these traits in sub-divided populations is rarely considered. We investigated evolution meta-populations spider mite Tetranychus urticae evolving under budding (pairing females from same patch) or random different patches) e...

During mitosis in budding yeast, cortically anchored dynein generates pulling forces on astral microtubules to position the mitotic spindle across the mother-bud neck. The attachment molecule Num1 is required for dynein anchoring at the cell membrane, but how Num1 assembles into stationary cortical patches and interacts with dynein is unknown. We show that an N-terminal Bin/Amphiphysin/Rvs (BAR...

In most meiotic systems, recombination is essential to form connections between homologs that ensure their accurate segregation from one another. Meiotic recombination is initiated by DNA double-strand breaks that are repaired using the homologous chromosome as a template. Studies of recombination in budding yeast have led to a model in which most early repair intermediates are disassembled to ...

background the aim of the present study was to compare two analgesic techniques for transrectal ultrasound (trus)-guided biopsy: diclofenac patch versus periprostatic nerve block with 1% lidocaine. objectives to study the efficacy of and compare diclofenac patch and periprostatic nerve block as analgesia in trus-guided prostate needle biopsy. patients and methods in total, 60 patients were pros...

GTPases are widespread in directing cytoskeletal rearrangements and affecting cellular organization. How they do so is not well understood. Yeast cells divide by budding, which occurs in two spatially programmed patterns, axial or bipolar [1-3]. Cytoskeletal polarization to form a bud is governed by the Ras-like GTPase, Bud1/Rsr1, in response to cortical landmarks. Bud1 is uniformly distributed...

In this paper, we propose a new compact quasi-fractal shaped microstrip antenna that consists of a hexagonal patch as the main radiator and a complementary stacked patch as the parasitic element. The overall surface of the proposed quasi-fractal patch is about 55% lower than the conventional hexagonal patch. Using of stacked technique, the gain reduction of compression technique is almost compe...
