Biomotors were once described into two categories: linear motor and rotation motor. Recently, a third type of biomotor with revolution mechanism without rotation has been discovered. By analogy, rotation resembles the Earth rotating on its axis in a complete cycle every 24. h, while revolution resembles the Earth revolving around the Sun one circle per 365. days (see animations The action of revolution that enables a motor free of coiling and torque has solved many puzzles and debates that have occurred throughout the history of viral DNA packaging motor studies. It also settles the discrepancies concerning the structure, stoichiometry, and functioning of DNA translocation motors. This review uses bacteriophages Phi29, HK97, SPP1, P22, T4, and T7 as well as bacterial DNA translocase FtsK and SpoIIIE or the large eukaryotic dsDNA viruses such as mimivirus and vaccinia virus as examples to elucidate the puzzles. These motors use ATPase, some of which have been confirmed to be a hexamer, to revolve around the dsDNA sequentially. ATP binding induces conformational change and possibly an entropy alteration in ATPase to a high affinity toward dsDNA; but ATP hydrolysis triggers another entropic and conformational change in ATPase to a low affinity for DNA, by which dsDNA is pushed toward an adjacent ATPase subunit. The rotation and revolution mechanisms can be distinguished by the size of channel: the channels of rotation motors are equal to or smaller than 2. nm, that is the size of dsDNA, whereas channels of revolution motors are larger than 3. nm. Rotation motors use parallel threads to operate with a right-handed channel, while revolution motors use a left-handed channel to drive the right-handed DNA in an anti-chiral arrangement. Coordination of several vector factors in the same direction makes viral DNA-packaging motors unusually powerful and effective. Revolution mechanism that avoids DNA coiling in translocating the lengthy genomic dsDNA helix could be advantageous for cell replication such as bacterial binary fission and cell mitosis without the need for topoisomerase or helicase to consume additional energy. © 2014 Elsevier Inc.

The effects of plateau width and step-edge kinking on carbon monoxide (CO)-induced restructuring of platinum surfaces were explored using molecular dynamics (MD) simulations. Platinum crystals displaying four different vicinal surfaces [(321), (765), (112), and (557)] were constructed and exposed to partial coverages of carbon monoxide. Platinum-CO interactions were fit to recent experimental data and density functional theory (DFT) calculations, providing a classical interaction model that captures the atop binding preference on Pt. The differences in Pt-Pt binding strength between edge atoms on the various facets were found to play a significant role in step-edge wandering and reconstruction events. Because the mechanism for step doubling relies on a stochastic meeting of two wandering edges, the widths of the plateaus on the original surfaces were also found to play a role in these reconstructions. On the Pt(321) surfaces, the CO adsorbate was found to assist in reordering the kinked step edges into straight {100} edge segments. © 2016 American Chemical Society.

DNA-damaging antibiotics such as ciprofloxacin induce biofilm formation and the SOS response through autocleavage of SOS-repressor LexA in Pseudomonas aeruginosa. However, the biofilm-SOS connection remains poorly understood. It was investigated with 96-well and lipid biofilm assays. The effects of ciprofloxacin were examined on biofilm stimulation of the SOS mutant and wild-type strains. The stimulation observed in the wild-type in which SOS was induced was reduced in the mutant in which LexA was made non-cleavable (LexAN) and thus SOS non-inducible. Therefore, the stimulation appeared to involve SOS. The possible mechanisms of inducible biofilm formation were explored by subproteomic analysis of outer membrane fractions extracted from biofilms. The data predicted an inhibitory role of LexA in flagellum function. This premise was tested first by functional and morphological analyses of flagellum-based motility. The flagellum swimming motility decreased in the LexAN strain treated with ciprofloxacin. Second, the motility-biofilm assay was performed, which tested cell migration and biofilm formation. The results showed that wild-type biofilm increased significantly over the LexAN. These results suggest that LexA repression of motility, which is the initial event in biofilm development, contributes to repression of SOS-inducible biofilm formation. © 2013 Institut Pasteur.

The question of where the low-metallicity globular clusters in early-type galaxies came from has profound implications for the formation of those galaxies. Our work supports the idea that the metal-poor globular cluster systems of giant early-type galaxies formed in dwarf galaxies that have been subsumed by the giants. To support this hypothesis, two linear relations, one involving globular cluster metallicity versus host galaxy luminosity and one involving metallicity versus velocity dispersion were studied. Tentatively, these relations show that the bright ellipticals do not obey the same trend as the dwarfs, suggesting that the low-metallicity globular clusters did not form within their parent bright ellipticals. © 2010 The American Astronomical Society.

This is a research report examining the influence of organizational politics perceptions on nurses work outcomes (job satisfaction, work stress, job burnout and turnover intention).Organizational politics is a phenomenon common in almost all institutions and is linked with undesirable consequences in employees.Despite the plethora of research around the world on this topic, studies describing organizational politics in nursing remain underexplored.A cross-sectional research design was utilized in this study. One hundred sixty-six (166) nurses participated. Five standardized tools were used: the Job Satisfaction Index, the Job Stress Scale, the Burnout Measure Scale, the Turnover Intention Inventory Scale and the Perception of Organizational Politics Scale.Nurses employed both in private and government-owned hospitals perceived moderate levels of organizational politics. Positive correlations were identified between perceived organizational politics and job stress, turnover intention and job burnout. Negative correlations were found between perceived organizational politics and job satisfaction.Perceptions of workplace politics in Filipino nurses were lower when compared to findingsin other international studies. A strong link was found between organizational politics perceptions and the four job outcomes (stress and burnout levels, turnover intention and job satisfaction).Use of a self-reporting questionnaire and exclusion of nurses from other provinces.Perceived organizational politics predicted nurses stress and burnout levels, turnover intention and job satisfaction.The findings of this study may provide a valuable perspective of this organizational issue and could assist policymakers and nurse administrators in formulating interventions that could minimize the effect of workplace politics.

DNA damage attacks on bacterial cells have been known to activate the SOS response, a transcriptional response affecting chromosome replication, DNA recombination and repair, cell division and prophage induction. All these functions require double-stranded (ds) DNA translocation by ASCE hexameric motors. This review seeks to delineate the structural and functional characteristics of the SOS response and the SOS-regulated DNA translocases FtsK and RuvB with the phi29 bacteriophage packaging motor gp16 ATPase as a prototype to study bacterial motors. While gp16 ATPase, cellular FtsK and RuvB are similarly comprised of hexameric rings encircling dsDNA and functioning as ATP-driven DNA translocases, they utilize different mechanisms to accomplish separate functions, suggesting a convergent evolution of these motors. The gp16 ATPase and FtsK use a novel revolution mechanism, generating a power stroke between subunits through an entropy-DNA affinity switch and pushing dsDNA inward without rotation of DNA and the motor, whereas RuvB seems to employ a rotation mechanism that remains to be further characterized. While FtsK and RuvB perform essential tasks during the SOS response, their roles may be far more significant as SOS response is involved in antibiotic-inducible bacterial vesiculation and biofilm formation as well as the perspective of the bacteria-cancer evolutionary interaction. © 2014 Wolfe et al.; licensee BioMed Central Ltd.

This integrated literature review examined factors associated with the ability of students to persist in an online course. Lack of persistence in online education and its' consequence of attrition, is an identified problem within the United States and internationally. Terminology has wavered between persistence and success, where each has been interchangeably used to characterize a student that completes a course and continues to program completion. Separate searchers were conducted in Academic Search Premier, CINAHL Plus, the Directory of Open Access Journals (DOAJ) Education Full Text, Ovid, and the Journal of Online Learning and Teaching (JOLT). Search terms included persistence, distance education, and online learning. Inclusion criteria included published after 1999, article from a peer-reviewed journal, and article addresses student factors leading to persistence. Exclusion criteria included article not related to factors of persistence, no original data, and article not written in English or not related to online courses. Factors associated with student persistence in an online program include satisfaction with online learning, a sense of belonging to the learning community, motivation, peer, and family support, time management skills, and increased communication with the instructor. Persistence carries the nuance of complexity beyond mere success. Factors unrelated to knowledge have the ability to provide support, thus allowing the student to overcome hardships in completing a course. If persistence factors are not present in sufficient quantity, the student may be at risk of withdrawing from an online course.
