Messenger RNA transport in the opportunistic fungal pathogen Candida albicans
Date: 2017-12-01
Creator: Anne E. McBride
Access: Open access
- Candida albicans, a common commensal fungus, can cause disease in immunocompromised hosts ranging from mild mucosal infections to severe bloodstream infections with high mortality rates. The ability of C. albicans cells to switch between a budding yeast form and an elongated hyphal form is linked to pathogenicity in animal models. Hyphal-specific proteins such as cell-surface adhesins and secreted hydrolases facilitate tissue invasion and host cell damage, but the specific mechanisms leading to asymmetric protein localization in hyphae remain poorly understood. In many eukaryotes, directional cytoplasmic transport of messenger RNAs that encode asymmetrically localized proteins allows efficient local translation at the site of protein function. Over the past two decades, detailed mechanisms for polarized mRNA transport have been elucidated in the budding yeast Saccharomyces cerevisiae and the filamentous fungus Ustilago maydis. This review highlights recent studies of RNA-binding proteins in C. albicans that have revealed intriguing similarities to and differences from known fungal mRNA transport systems. I also discuss outstanding questions that will need to be answered to reach an in-depth understanding of C. albicans mRNA transport mechanisms and the roles of asymmetric mRNA localization in polarized growth, hyphal function, and virulence of this opportunistic pathogen.

GREEN-PSO: Conserving function evaluations in Particle Swarm Optimization
Date: 2013-11-18
Creator: Stephen M. Majercik
Access: Open access
- In the Particle Swarm Optimization (PSO) algorithm, the expense of evaluating the objective function can make it difficult, or impossible, to use this approach effectively; reducing the number of necessary function evaluations would make it possible to apply the PSO algorithm more widely. Many function approximation techniques have been developed that address this issue, but an alternative to function approximation is function conservation. We describe GREEN-PSO (GR-PSO), an algorithm that, given a fixed number of function evaluations, conserves those function evaluations by probabilistically choosing a subset of particles smaller than the entire swarm on each iteration and allowing only those particles to perform function evaluations. The "surplus" of function evaluations thus created allows a greater number of particles and/or iterations. In spite of the loss of information resulting from this more parsimonious use of function evaluations, GR-PSO performs as well as, or better than, the standard PSO algorithm on a set of six benchmark functions, both in terms of the rate of error reduction and the quality of the final solution.
Galileo, poetry, and patronage: Iulio strozzi's venetia edificata and the lace of galileo in seventeenth-century talian poetry

Creator: Crystal Hall
Access: Open access
- The Venetian poet and librettist Giulio Strozzi (1583 -1652) spent much of his career glorifying he Serenissima through a series of theatrical pieces. His only epic poem, the Venetia edificata (1621, 1624), while ostensibly a celebration of the republic, shows a level of commitment to alileo Galilei (1564 -1643) and to Galileo's science that is unique among poets of the time, enetian or otherwise. It is the apex of Strozzi's artistic project to incorporate Galileo's discoveries nd texts into poetic works. The Venetia edificata also represents the culmination of a fifteen-year ffort to gain patronage from the Medici Grand Dukes in Florence. While the first, incomplete ersion is dedicated to the Venetian Doge, the second, finished version is dedicated to Grand DukeFerdinando II de' Medici of Florence. More than a decade after Galileo's departure from the eneto to Florence, Strozzi cites from Galileo's early works, creates a character inspired by Galileo, ncorporates the principles of Galileo's science into the organizing structure of the poem, and nswers one of Galileo's loudest complaints about Torquato Tasso's Jerusalem Delivered (1581). trozzi's strategies both in writing the Venetia edificata and in seeking patronage for it underscore he ambivalent response to Galileo in contemporary poetry.
